Yet, also the individual components or the entire equipment group 44 of equipment group 44 can be arranged on the finishing station, so that can regulate with respect to base surface 19 and finishing station 20 no matter these.This freely selects according to the concrete condition of part and the requirement of equipment.
Turning up the soil to simplify with the ratio of amplifying and partial cutaway in Fig. 3 and 4 shows a separator, be separator 30 at this, and in order to understand the principle of work and power better, identical parts adopt and illustrate reference character identical in 1 and 2 and represent.For the simplification and the standard of accompanying drawing, at the construction package of this cooperation that does not illustrate with reference to previous drawings.
Comprise a housing 52 at the separator shown in this 30, it defines a collecting chamber 53.Above-mentioned discharge tube 33,34 and inflow pipe 40 feed in this collecting chamber 53.As mentioned above, extract out from negative pressure pond 14 to 16 through pipeline 40 under the mating reaction of negative pressure device 24 and cyclone separator 29 by the mixture that gas and liquid medium constitute, thereby in collecting chamber 53, form a liquid level 54.
By inflow pipe 40 is fed in the collecting chamber 53, preferably in the side regions on top,, when mixture enters in the collecting chamber 53, under the acting in conjunction of gravity, be separated into liquid and gaseous state composition here because the density of each component is different with proportion.Liquid constituent or medium 26 are deposited on the bottom section 55 of housing 52, and discharge tube 33 feeds in this housing 52.At relative with bottom section 55, the upside of housing 52 just, discharge tube 34 feeds collecting chambers 53 from the top area 56 of housing 52.As can be seen from the figure, the discharge tube 34 and first discharge tube 33 spatially separate, that is, one another is at bottom section 55 in top area 56, and wherein, liquid medium 26 is taken away by discharge tube 33, and gas medium is taken away from discharge tube 34.
A floating installation 57 also is set in collecting chamber 53, and it is connected with a controlling device 58 mating reactions ground.A closure 60 of a valving 61 is set in the zone of the port 59 of discharge tube 33 in collecting chamber 53, and it is connected with a controlling mechanism 62 of controlling device 58.Cooperating of controlling mechanism 62 by floating installation 57 and controlling device 58, when liquid level on the Vertical direction 54 changes, described controlling device 58 is adjusted to the enable possition with valve mechanism 61 from closing position as requested, like this, by the unlatching of valving 61, can discharge to cyclone separator 29 by discharge tube 33.
Advantageously, 64 direction is extended stretch into a guide element 63 in other words port 59 from port 59 along the longitudinal axis, and itself and closure 60 join, and like this, when regulating closure 60, guarantees longitudinal guide controlling mechanism 62 on the direction of the longitudinal axis 64 all the time.Preferably, selected sliding fit between the internal surface of port 59 and guide element 63 is so that can carry out smooth adjusting between these two members in opposite directions.It is favourable selecting the length 65 of guide element 63 like this, that is, guide element 63 is put in the port 59 all the time from closing position when move the enable possition of maximum, thereby constitute a support device 66.
For fear of gaseous medium being sucked discharge tube 33, liquid level 54 is selected like this with respect to port 59 on the direction of the longitudinal axis 64, that is, have only when the liquid level 54 of operating floating installation for the first time is located at the top of port 59, operate for the first time floating installation, thereby just closure is lifted from port 59.So just guaranteed that port 59 is arranged on below the liquid level 54, begun to move to the enable possition by floating installation 57 operation closures 60 from closing position in this liquid level.
In order guide element 63 in controlling mechanism 62, the particularly port 59 and closure 60 not to be obtained accurate adjustment movement under the situation of the supporting surface chamfered edge of the sealing on the port 59, advantageously, the controlling mechanism 62 of controlling device 58 is slidably supported in another support device 67 in a side relative with first support device 60 of housing 52, and this support device is aimed at coaxial in other words with first support device.By two such fraction support devices, controlling device 58 is accurately vertically regulated on the direction of the longitudinal axis 64, can also guarantee the supporting surface that closure 60 seals like this on port 59.Described another support device 67 is a cylinder piston device 68 at this, and wherein, piston 69 is connected with controlling mechanism 62.If piston 69 is designed to labyrinth sealing on its outer periphery, then between this piston and cylinder wall 70, form a kind of sealing, this sealing is simultaneously adjustable on the direction of the longitudinal axis 64.Like this, by piston 69 collecting chamber 53 of housing 52 and the cylinder chamber 71 of cylinder piston device 68 are almost separated on aeroseal ground.
By connecting discharge tube 34 and make throttle mechanism 39 coupled condition that mediates, under the mating reaction of negative pressure device 24 and cyclone separator 29, in collecting chamber 53, for example obtain-0.1 relative negative pressure of crust or the absolute negative pressure of 0.9 crust.Principal pressure in first discharge tube 33 is preferably-0.7 crust relative pressure or 0.3 crust absolute pressure.Because above-mentioned pressure reduction when liquid level 54 is low in collecting chamber 53, is sucked on the port 59 closure 60, like this, liquid medium 26 may flow out from collecting chamber 53 equably by discharge tube 33 hardly.Therefore, advantageously, the cylinder chamber 71 of cylinder piston device 68 on a side that deviates from controlling mechanism 62 of piston 69 passed piston 69 and controlling mechanism 62 and first discharge tube 33 and flowed and connect, and be like this, identical in the leading pressure in this cylinder chamber 71 and the discharge tube 33.This can for example realize like this that promptly, controlling mechanism 62 portion within it has a connecting hole 72, and it passes closure 60 and piston 69 extensions from discharge tube 33.
In addition, in order to obtain pressure ratio much at one, make the piston area 73 of piston 69 in the zone of cylinder chamber 71 corresponding with a cross section 74 of valve seat in the port 59 of first discharge tube 33 regional.
The extrusion equipment 1 of making article 5 according to predetermined in service, carry liquid mediums 26 by supplier 23 at least one negative pressure pond 14 to 16, and form discharge under the pressure condition less with respect to ambient atmosphere pressure a kind of by liquid medium and the gas medium mixture that constitutes of air particularly.Next this mixture is imported in the separator 30 to 32, in this separator at least in part, preferably almost entirely separate, and the liquids and gases medium is drawn in the shared cyclone separator 29 from separator 30 to 32 by the discharge tube that is separated from each other 33,34.
It is important in this that pumping liquid medium 26 just reaches the degree of predetermined minimum liquid level from separator 30 to 32, at this moment, has only liquid medium 26 to extract out from collecting chamber 53, and gas medium, particularly air are not extracted by discharge tube 33 out.Therefore, the design that cooperates with floating installation 57 of the liquid level in the collecting chamber 53 54 height has guaranteed almost to have avoided in other words above-mentioned situation.Preferred pump liquid medium with aspirator 25 from the bottom section of the internal cavities of cyclone separator 29 all the time, simultaneously, shared central negative pressure device 24, particularly one or two vacuum pump 37 be the intake-gas medium all the time.
From diagram 4, can more be clear that about separator 30, in the present embodiment, this separator has different spatial forms on its longitudinal extension section, almost be circular in the zone of inflow pipe 40, and roughly be oval-shaped in the zone of discharge tube 34.It is to be noted at this, the distribution of shown spatial form and floating installation 57, the controlling device 58 that has valving 61 and support device 66,67 and structural design are just exemplarily selected some possible schemes, also can select other distribution and structural design certainly.
In the present embodiment, by one in collecting chamber 53 support arm 75 of rotatable support device 76 with floating installation 57 fixed-site but rotatably be supported on the keeping arm of not describing in detail.From illustrating 3 and 4 as can be seen, a retaining mechanism 77 passes two support arms 75 and controlling mechanism 62, and with floating installation 57, particularly its support arm 75 is connected with controlling mechanism 62 motions of controlling device 58.By this Lever type device, when the liquid level in the collecting chamber 53 54 raises, be elevated to always closure 60 is lifted from the port 59 of discharge tube 33.By floating installation 57 and this mating reaction of controlling mechanism 62 and the unlatching and the sealing motion of closure 60, constituted to be used to regulate and entered the valving 61 that the discharge of discharge tube 33 is flowed from collecting chamber 53.
Point out at last, in order to understand the structure of supplier better, to amplifying and/or dwindle expression in not to scale (NTS) ground on its parts part.
From specification, can draw the basic goal of independently scheme of the present invention.
At first, each constitutes the theme of independently scheme of the present invention in the form of implementation shown in Fig. 1,2,3,4.Xiang Guan purpose of the present invention and scheme can draw from the description to these accompanying drawings therewith.
