Description

CRUSHING PUMP STATION TECHNICAL FIELD The invention is generally referred to as pumps-crushers, in particular, the invention relates to stations used to house crusher pumps.

BACKGROUND INFORMATION 0 Currently, low-resourc- esystems, driven by crusher pumps, are a desired alternative for conventional gravity dewatering systems and the use of septic tanks. Pump systems - crusher Black waters are now widely accepted and popular means of managing residential waste, where conventional gravity drainage systems may not be practical, or are expensive, requiring high cost materials and significant labor. The environmental reasons have also forged many communities to look for alternatives for both conventional gravity drainage systems and the use of septage tanks. Keeping costs to a minimum and providing an effective storage of waste water, conditioning and transportation, the pump 5 crusher systems provide a rational and cost-effective alternative to conventional a u management systems. Of waste, Although the objects associated with the installation, fun < , ionaini ent o and mant n i n t i n g of the is < If the pump crusher rings are significantly smaller than those of the conventional gravity drainage systems, the installation of a crusher pump remains as a replacement for the total cost of a drainage pump crusher system. Pintos de The installation of a t ri-t ui adora pump, an engineer or topographer of-t epni nara typically the height of a housing for the crusher pump, change called a crusher pump station, needed for a particular site Despite this determination of pre-installation height, it is common to find obstructions in the field, eg, a rock deposit, etc., which sometimes require a more expensive excavation effort. An alternative for the additional excavation is the modification of the height of the crusher pump station in the field .. In the past, the preferred material for the crusher pump stations has been the r idrio 0 Although non-corrosive rglass has played its role satiaily, several disadvantages are now apparent. First and foremost, rglass is a relatively expensive material. The modification of the height in the field is also difficult with the glass r stations. Typically, the height adjustment is limited to long increments, such as 457.2 rnm. Long-term modifications, however, do not provide adequate flexi-ty on the adjustment of the height of pump stations in the field. Qtrct disadvantage associated with pump stations' > rglass crusher is that after installation, the wall-glass rglass can be pushed or pulled by buoyant forces of groundwater causing the stations to "float" on their locating installation. To prevent this movement, the 1U concrete of the stations is sometimes necessary. The ballasting with concrete, however, requires a greater effort of excavation and installation, finally adding an additional cost. Another problem encountered with the rglass crusher pump stations is the leak paths of the underground water that may arise through the walls of the stations. These leakage paths tend to occur where the entry, exit and adjoining surface openings are prepared in the field during installation. The pump stations r crusher glass also have a limited tolerance in the careless handling, which commonly occurs during boarding and installation. Transportation and installation is commonly agitated, and as a result, rglass stations may suffer structural damage during their bundle.

Unfortunately, however, the damage to the station can not be predictable until after the installation has been completed and the leak begins. The fiberglass also has a limited ability to withstand the abrasive effects associated with the drainage liquids. To compensate for the various disadvantages associated with fiberglass stations, it is believed that stations made of other materials are now available. A known turing pump station which is not made of fiberglass, includes a fully molded station formed of polypropylene. Although this known station avoids the use of glass fiber, retains many of the disadvantages associated with fiber stations < ie glass, including the difficult field height adjustment and limited structural integrity. In addition, this flexible propylene station is not available with the crusher bob installed in it, L5 and, therefore, its installation in the field is still laborious. The installation of the crusher in the field also exacerbates the emergence of underground water leakage paths through the various inlet and outlet openings. the station created during installation. In this way, there is a need for a crusher pump station that has an improved structural integrity, which has a simple installation, which allows height modification in the field in small increments without adjoining electrical and ventilation surfaces. , and that is highly resistant to corrosion, all at reasonable cost.

BRIEF DESCRIPTION OF THE INVENTION Briefly, the present invention is in need and overcomes the disadvantages of the prior art through the provision of a crusher producing station capable of having its height adjusted in the field during installation, which includes : a substantially cylindrical internal wall having an internal surface and an outer surface, on the inner surface of the Ll) internal wall I define a cavity for the insertion of a bornba crusher; an external cylindrical substance that has an internal surface and an external surface, wherein the external wall has a greater diameter than the inner wall; a plurality of rigid members that extend between the Internally substantial cylindrical internal wall and the substantial external cylindrical wall, each plurality of rigid members being fixed to the inner wall and each of the plurality of rigid members being hooked to the inner surface of the outer wall; and a willing base adjacent to a lower portion of the inner and outer walls.

DETAILED DESCRIPTION OF THE INVENTION Referring now to the drawings, and more particularly to the exterior view of Figure 1, a crusher pump station 10 is positioned substantially vertically on the floor. The crusher pump station 10 includes a lid assembly 22, an upper tank portion 1.4, a transition section 18, a lower tank portion 16 and a base 32. The outer walls of the upper tank portion 14 and the lower tank portion 15 are corrugated, while the outer side wall 17 of the transition section 18 is preferably smooth. Extending < * t through the side wall 17 of 1 »" -ec tion Ao transition 10 is an inlet opening 20 through which the black water to the crusher pump station * 3! 10, and a discharge opening 19, through which the processed sewage water leaves the crusher bornba station 10. Attached to the upper tank portion 14 is a lid assembly 22. Fi lid assembly 22 includes the adjacent, rich, and ventilating surfaces of the pump station with the crusher as will be described below and subsequently described herein, and an access hatch to enable a person between the inside of the crusher pump station 10. A protective conductor 26, fixed to one side of the lid assembly 22 by means of a guard 30 provides a pr-otector housing for an electric power cable 0. 32 is secured to the lower portion 16 of the tripping station 10. The pr Each of the aforementioned components, ie, the upper tank portion 14, lower tank portion 16, transition section IB, cover assembly 22 and base 32 are separately constructed and fixed to one another through several methods, which will be described later in detail. Figure 2 is a Latitudinal sectional view showing the interior of the LO crusher pump station. Mounted within the crusher pump station LO is a crusher pump unit 34. The crusher pump unit 34 includes a crusher head 36 for spraying sewage.

The 38 mc crusher pump carries a discharge housing 40, which is connected to a discharge outlet pipe 42. A liquid and airtight control housing contains the controls of the crusher block 34 (v.gr). ., pressure switches, start times, etc.), and a lower housing 44, a motor housing casting 47 accommodates an electric field (not shown) used to power both the crusher pump 38 or to the crushing head 35. T uming pump unit 34 employs one or more sensor tubes 6 to sense the pressure variations by measuring the increases in the level of black water stored in the LO water crusher. Until there is a predetermined level of sewage, the engine within the engine housing casting 47 will be energized. These sewage collected at the crusher bornba station 10 will then be crushed by the crusher head 36 and subsequently pumped by the crusher pump 38 from the discharge nozzle 40 to the discharge outlet pipe 42. From the outlet discharge pipe 42, the processed sewage will travel to a remote location, eg, to a master sewage pipeline and finally to a sewage treatment plant.

Mo. 28,104 issued to the company, commonly owned by the present invention and the present invention, Lviron ont One Corporation, and entitled HJMP 10RAGE b GRINDER, the description herein is incorporated herein by reference. reference in its entirety to L idad. A preferred modality of the tank portions 14 and 16 of the crusher pump station 10 will be described below. Preferably, the portion of < nque superior 14 and The lower tank portion 16 are identical in all respects, apart from their relative height. Both the upper tank portion L4 as well as the lower tank portion 16 have a non-corroborated internal part of the Lindrica 5? secured to an outer wall corrugated substance Lrnent e Lín cilindrica 54. As seen from the side in Figures 1 and 2, the outer corrugated wall 54 is wave-shaped, forming a series of alternating ridges 56, that is, ridges and ribs 58, i.e., grooves. Preferably, each valley 5T of the corrugated par-ed 54 is secured, during the process of , to the inner wall 52. In the preferred embodiment, an extrusion manufacturing method is employed to form the corrugated configuration, while the outer cylindrical corrugated wall 54 and the inner cylindrical par'ed 52 form an integral double top tank portion wall 14 and a lower tank portion 16. The preferred double wall corrugated configuration provides hardness and structural rigidity. Also, the double-walled structure is less sucoptible to drilling. After installation on the floor, the ground will tend to get stuck between the alternating corrugations, thereby anchoring the station 10 securely therein, and eliminating s? time or reducing the need for a concrete ballast. Preferably, the portions of an 14 and 16 are constumed from a thermoplastic, such as high density polyethylene. High density polystyrene is preferred because it has the following characteristics: resistance to stress cracking; durability at low tempera tures; welding capacity; corrosive resistance to a wide variety of chemicals; impact resistance and mechanical strength. In case an obstruction is found during the installation in the field, the height of the upper tank portion J4 can be modified by an installer, who will simply use a common tool, such as a hand saw to cut it. unnecessary length of the tank. Preferably, the installer will remove the corrugated from the upper part or the corrugated part from the upper tank portion. If the installer needs to remove only one corrugate, the corrugated from the upper part will be removed. cut at its lower end - through the corrugated plus "Alto." Cutting only one corrugated, the height of the crusher bornba station 10 could be reduced approximately 79.38 nm, which is the length corresponding to corrugated of the L3 proffered modality. Although it is not commonly corrugated to approximately 3.30 mm, it is understood that other units can be manufactured with a different corrugation length, thus allowing a finer height modification. If an additional length is required to be removed from the upper tank portion 14, the installer can cut a series of corrugations, in case the length of the station is too short, a length can be added. additional to the share of your L4 er, through) a The provision of a known water-tight coating (not shown), which connects to a tank extension (not shown) of identical structure to the tank portions 14 and 16 .. Tai tight coupling ai water is manufactured by Advanced Drainage Systems of LudLow, Massachusett. Ib Each corrugation in the upper and lower tank portions 14 and 16 defines a hollow cavity 60 that extends around the periphery of the same. It must be understood, however, that each cavity 60 can be filled in. For the purposes of manufacturing economy and weight reduction total of the station, the corrugated of the hollow cavity is preferred. It should also be understood that the upper and lower tank portions may comprise certain circumstances of a smooth outer wall and / or a single wall structure, as long as the wall is of a '.- > "" Sufficient structural strength However, from the point of view of cost and structural rigidity, double-pair stiffness is preferable with < rrig-ac &on of external corrugated parod. certain adverse soil yields, eg, where clay and silt are present, it may be convenient to have a smooth cylindrical outer wall, instead of a corrugated external par'ed, for a crusher bornba 10 station. this way, various circumstances may favor a smooth outer wall on the corrugated outer wall 54 illustrated in Figures 1 and 2. Accordingly, in another embodiment of the present invention, as illustrated in Figs. 6-8. , an outer wall oiLindpca Lisa 55 can be fixed or otherwise hooked to a corrugated wall centirably disposed 54A "Pr, a smooth external wall 55 will be constructed of a material similar to the other walls of the pump station crusher 10. Co or illustrated in The Fixtures 6-8, The corrugated par 54A acts as the inner or central wall between the outer wall 55 and the inner wall 52. Essentially, the centrally disposed corrugated wall 54A defines a plurality of rigid members or pigeon members, that is, a series of crests 56A and valleys 53A, extending between the inner wall 52 and the outer wall l sa 55 so that each rigid member is fixed to or engaged with the outer surface of the inner wall 52 and the surface internal of the smooth outer wall 55. However, it should be noted that the present invention is not limited to a wall 'or? rugada < - in »r ** > I'm willing '0, but they can be Right'. Any rigid members that lie between the wall i and 52 and i-1 wall e terna 55 that are located between the two, provided that they facilitate the structural integrity of the crusher pump station 10. Poi For example, a series of rings, rings, or ribs could be used-like small pieces. As can be seen in the transverse section in FIGS. 7 op, on the wall 52 and the centrally disposed corrugated pair 54A, a plurality of hollow channels or cavities 60 extend as a + e + eve arc. the same. Similarly, between the corrugated wall 54A and the smooth outer wall 55, a plurality of channels 51 extend around the periphery of the crusher pump station 10. In order to increase the structural integrity of the crusher pump station 10, A filler material can be removed in some or all of the channels b and 61. Any known means can be fixed in the attachment and hooking of the smooth outer wall 55 to the corrugated wall 54A. For example, a smooth outer wall 55 can be placed * around and welded to the corrugated wall 54A (see Figure 7). Another method of attachment could be to extrude the outer wall 55 with a diameter slightly larger than the diameter of the corrugated wall 54A, and then to place it around the corrugated wall 54A and shrink it by heating to engage it with the corrugated stool 54A. The pan-d extern- »1 i - ^ r, 5 < Amblen can be formed integral to the corrugated pair-ed '> 4fl of the LO crusher pump, for the sake of it, ip d tan t o?

The wall «nx erna lisa 55 will create a sliding or sliding surface around the external surface of the crusher bornba station 10. Unlike a crusher pump station (this has a corrugated wall external 54, where adjacent corrugations tend to accumulate soil and materials between them, the outer surface of the smooth outer wall 55 prevents such accumulation. If a larger sliding surface, thin covering or fabric 57 (see Figure 8) is desired, such as a geotextile fabric or netting, it can also be placed around the smooth outer wall 55. Preferably, it should be left The fabric 57 slides in relation to the outer surface of the smooth outer wall 55 to facilitate an even surface sliding surface and other material that rests against the crusher pump station 10. The addition of a smooth outer wall 55 will improve the axial rigidity and overall resistance of the crusher bornba lü station. Due to the improved stiffness and durability resulting from a three-walled system, compared to) One-wall or two-wall systems can be reduced in size and cost, as illustrated in Figure 6, it is not It is essential that the outer wall Lisa 55 extend over the entire length of the crusher pump station LO.Therefore, it may be desirable to have an exterior wall that is smooth to extend approximately one portion of the longitudinal length of the station 10. For example, under certain circumstances, v, gr., where a freeze push is foreseen, can it be convenient to have a lower tank portion L5 of the tpt pump station? Remaining 10 corrugated m intro the sculpted tank portion 14 has a smooth outer wall 55 .. Depending on the environmental conditions, a turing pump station that has its outer wall partly corrugated and partially smooth may Increase Stability and Performance of the Est., in em However, other circumstances may determine a crusher pump station where the outer smooth wall extends to the entire longitudinal extent of the crusher-driven station 10, even if there is no transition friction L8. Within the crusher pump station 10, a dry well 62 and a wet well 54 are defined by the interior wall of the upper tank portion 14 and the interior parod of the lower tank portion 16, respectively. In this way, the dry well 62 is an internal cavity that 1H Corresponds the portion of you that superior l '+, and the wet well f-j os an intoxicated cavity that corresponds to the portion of inferior tank- Ib. The heating section 18 provides a protector between the dry well 62 and the wet well 64. The crushed pump unit 34 is secured to the "transitional 18" already in the wet well 64 to the length of the longitudinal axis of the tank portions 14 and 16. The sewage flows from the entrance nipple 66 to the opening 20 in the transition section 10 and into the wet well 64, where the sewage is subsequently processed in the turing pump unit 34. For detail, about the operation and structure of the dry well and wet well of the present invention, refer to US Patent No. 4,014,475, issued to Grace et al., commonly owned by the assignee of the present invention, Envi ronmont One Corporation, and entitled COTlBENfc.D IANWAY AND COL LL-IC TlüN TA K FOR SFUIAGE GRIMDER, the description of Which is incorporated herein by reference in its entirety, separating the portion of t The upper section 14 of the lower tank portion 16 is the transition section lñ, which is preferably composed and manufactured separately from the crushing station 10. The transition section 18 is substically cylindrical. in form, it has an uncorrugated outer wall to facilitate the formation of one or more inlet openings 20 and a discharge opening 19 through its openings, and it has an opening to L l .- »lar-j -» d < s that? * extends -: n (-1 mi mo.) As the fi rm is moved, the entree Ao 20 is preferable daily to the discharge opening 19. Li. The opening of the opening 20 as the outlet opening 19 is formed directly in the wall of the tension section 10 to avoid the need for penetration during installation in the field. A synthetic rubber ring 27 or the like is used in the inlet aperture 20 for the rat race or the coupling of the inlet tube 66, like a normal PVC tube. the unit of bo ba tpt? radoi 34, is assembled upwardly at 41 for vertical release through the wet well 64 (along the side of the crusher pump unit 34), passes upward from the wet well 62, it wraps around again on the 43, and connects to the top of a conventional ball valve assembly located at 21. A valve handle 121, reliable to the ball valve assembly 21, provides the to close the ball valve during the removal of the crusher pump unit 34 from the station 10. The tube 42 extends posteriorly from the bottom of the ball valve assembly 21, where it is fixed to a flange 13, which is located adjacent to the opening 19. A seal ring (not shown) can be used in conjunction with the discharge plumbing described herein to facilitate a leak-proof seal.

The axially extending opening of the IR ransition section Accommodates the axial insertion of the crusher pump unit 34, the Transition section L8 includes an inner diameter and an outer diameter. The integer diameter is defined by the axial opening, and the outer diameter is ine by the outer side wall 17. An internal comea wall 118 forms the upper interior portion of the transition section 18, where the par'ed comes 1J8. It widens inward from the outside diameter towards a close proximity to the inner diameter of the transition section. This conical shape provides structural rigidity for the transition section 18 and facilitates the insertion of the crusher pump unit 34 into the axial opening of the transition section J8. Also for facilitating the structural stiffness of the transition section 18, a plurality of elbows L20 may be deployed outwardly from the inner diameter toward a proximity close to the outer diameter of the bottom of the transition section J8. The crusher drive unit 34 is suspended in the po, or moj 64 through the support of the tension section 10. To facilitate the attachment of the crusher pump unit. 4 - »Ja < -element transition 10, peripheral edge 35 of the transition section 18 receives a peripheral rim 149 Ao? na top plate 4b of the crusher pump unit 54. The top plate 45 is integrated L aJ corit housing i oi 44 of the crusher bornba unit 34 .. The perimeter edge 35 includes a plurality of threaded inserts equal spaced J ?, each of which < -e is aligned with a corresponding plurality of equally spaced openings 39 of the slanted rim 149. Tubular combs (not shown) pass through the openings 39 and are screwed into the threaded inserts 37, thus mechanically securing and sealing the upper plate 45 of the crusher pump 34 to the transition section 18. Privilegedly, a connection to air and water tightness was achieved. Prefei ibl órnen, the transition section 18 is manufactured using an injection molding manufacturing method. Also, it is preferred that the transition section 18, as well as the upper tank portion 14 and the lower tank portion-Ib, be constructed of an oplasting device, such as the high density polyethylene. The transition section 18 is a component of the LO crusher pump station manufactured separately, separated from both the upper tank portion 14 and the lower tank portion 16 to which the transition section 13 is attached. Techniques have been developed to connect a moplast to Jesus, such as the high density polymer, of which the supepoi tank section 14, lower tank portion 16, transition section 10 and base 32 are preferably compounds.

Alternatively, an inductive soldering technique can be used, the extrusion soldering is also another known technique for joining tepnoplastic components together. The union of the components can also be controlled by mechanical means in conjunction with secondary sealing adhesives. To facilitate matching of the transition section J8 with the upper tank portion J4 and the lower tank portion 16, the upper and lower boards of the transition section 18 can have a b? sela »Jo pep Cerrico edge at 15, thus providing a greater surface contact for the matching components.

The access gate 24 is secured to the taff assembly 22 and provides a convenient opening or access to the dry well 62. The access gate 24 includes a packing (not shown) which is frictionally fitted to the assembly. of cover 2? , providing a leak proof seal. The access gate 24 includes an interior face that is exposed to the atmosphere. The outer port of the access gate is preferably in the form of a dome and may include a series of channels 29 to facilitate the drainage of liquids, such as water. The access gate 24 can be adjusted with a means for closing The access gate 24 to the tafia assembly 22. The access gate 24 is made prerequisite of a non-toiro ive, tai, or non-polyester material.

The ventilator device 86 may be located adjacent to the electric quick disconnect RO, co, or shown in Figures 2, 4, and 5, or other Locifications O may be selected for the position of the ventilator '86 as length of the cable 20. Preferably the access path Limited air 84 does not extend over the entire length of the cable 28. For example, it is not necessary for the limited air access path 84 to extend from a point 5 per cent from the ventilator device 06 to the point where the cable 28 is connected to a power source (not mo strada). An encapsulation material 184 can be used to join the air access path 84 in such locations. 0 The flow of air from the respirator device 86 to the control housing 44 provides atmospheric pressure to the housing 44. In the case of (the dry well 62 is accidentally flooded with water, the ventilator device 06 avoids the flow of liquid towards the limited access path of air 04 5 of the electric cable 28. The ventilator device 86 includes a peripheral sleeve 88, which is hermetically secured on leakage around the air gap. electric 28. lli ai re '-14 iaja afia e1 * de? n Side of the peri ear cuff (38 and a tube 90 connected to the air side 94 for a * - * 26 air to the air access road limited by air 04 of the cable 20. While the air can pass through the protector 92, the liquid can not do it.A preferred material for the pr-otector 92 is GORE IFX. - 86, described above, or a place To the ventilating device '86, a breathing valve device (not shown) can be employed to prevent water from entering the inside of the rear window, the description of which can be found in FIG. '.LLCLCit? d of North American Patent pending Series No. 08/060, 430, presented above, common property of the assignee of the present invention, Environ ent One Corporation, and filed on May 1, 1993. This application for a pending document Nort earnen cana pr esont ada ant er lorrnent is expressly incorporated as reference at the moment. Briefly, this breathing valve device (not shown), by providing a movable activated pressure float, allows the flow of air to pass through it while avoiding the flow of the liquid at the same time. The base 32"is secured to the lower tank portion 16 using one of the known techniques, described above, to join together thermoplastic materials. Referring again to figure 2, base 32 is: configured in the form of a plate and preferably has a spherical inner bottom inferior 31. which is facing upwards. Fsfa confinura osfenca acts to force 27 gravitationally and hydrostatically The suspension of sewage to a central location of base 32. More particularly, the solid suspension of sewage is shoveled under The crusher head 36 for suction to the crusher pump unit 34 , preventing thus The corrosive and scouring effects of the particles The hard and stagnant effects of the black water inside the wet well 64,. The bale 32 includes • a pair-to-attach means-a conveyor belt (not shown), for example a pallet to secure rigid support during shipping. Means for joining may include a plurality of peripherally spaced apertures 33, which receive conventional bolts. After the manufacture of Lvidual.es induction crusher station components, described above, the individual components are insured at the factory. For example, the upper tank portion 14 is secured to the transition section 18, which in turn is secured to the lower tank portion Ib, which in turn is secured to the base 32. Then, the interface openings they are adjusted with corresponding washers, joints or similar. After assembly and attachment at the factory of the individual components of the extension 10, the crusher pump unit 34 is mechanically secured to the transition section 18 of the crusher pump station 10. The different conduits and cables are then joined; for example, the discharge duct 42 (d) extends in the interior of wet well 64 and the dry well 62 is attached to the ball valve 21, the flange 1.3, and a sealing washer (not shown). Now, the crusher pump station 10, which includes the crusher pump unit 34, is ready for e1barrage.Pre-boarding, typically, a consultant engineer or supervisor will determine the height of the station required for the operation. particular work .. Once the height of the station is determined, the management station 10, which includes a crusher pump unit 34 and associated piping, etc., will be delivered to the site, where excavation and installation If during the installation in the field it is verified that an alternate station height is necessary, the height of the station can be easily adjusted, for example, during the excavation, a bed of rocks can impede the excavation process In such a situation, the. Installer can avoid a more expensive excavation simply by modifying the height of the crusher pump station. If the height of the station needs to be reduced, the installer simply removes the lid assembly containing the electrical and ventilation interfaces and then uses a common tool such as a handsaw, to cut the unnecessary length of the upper tank position 14. In the case of ¡2 If additional tank length is required, airtight water-tight storage can be used (not shown) and a tank extension (not shown) will add-length. Although various aspects of the present invention have been described and depicted herein, those skilled in the art can perform alternative aspects to achieve the same objectives. For example, while the preferred embodiment employs a double-walled outer corrugated tank, a single wall station may be used under certain circumstances, or, under certain circumstances, a three-walled station having a double wall. Smooth outer can be preferred over a two-walled station having a corrugated outer wall.In addition, the tank may be formed in other configurations than the cylindrical one.Furthermore, although the specific manufacturing methods have been described herein, the different components of pump crusher station 10, other different methods may also be suitable. Also, although the transition section is described, some crusher pump stations, especially those that accommodate free-standing or rail-mounted crusher pump units, can operate without the need for a transition section. Therefore, it is intended that the aforementioned alternative aspects be covered by the appended claims, since they fall within the true spirit and scope of the invention.
