Description

{livestock manure treatment machine} with multiple structure

The present invention relates to a livestock manure treatment machine having a multiple structure, and more specifically, to a livestock manure treatment machine having a multiple structure capable of treating a large amount of livestock manure at once by installing a plurality of rotating shafts, blades, and conveying screws inside a container body.

As the population increases and industrialization develops, a large amount of livestock waste (hereinafter referred to as “livestock waste”) is being dumped into rivers, oceans, and soil, causing major environmental pollution. In other words, the livestock waste that is dumped in this way produces a strong foul odor as it decomposes, and the pathogens that grow there have a direct or indirect negative effect on human health and hygiene, and also pollute water sources.

To solve these problems, methods have been proposed to mix and compost livestock manure with moisture regulators such as sawdust using a mixer and recycle it as compost and raw material for compost. However, livestock manure itself has a high moisture content and requires a lot of moisture regulators, so there have been difficulties in supply and demand due to shortages of moisture regulators such as sawdust. In addition, the monthly maintenance and operating costs that each livestock farm has to bear have reached a considerable amount, causing economic difficulties.

In addition, a method of converting livestock manure into liquid fertilizer (hereinafter referred to as “liquid fertilizer”) by fermenting and composting some of the manure using aerobic microorganisms has been proposed, but this also does not go through a sufficient composting process, so the total nitrogen (hereinafter referred to as “total N”) component, which is contained in large quantities in livestock manure itself, is high, resulting in a phenomenon of accelerating soil devastation rather than being considered a fertilizer.

Recently, some facilities have been released that view livestock manure purely as waste and focus on reduction, but most facilities lack specialized knowledge about the characteristics of microorganisms and the role of complementing conflicts between facilities, so they are unable to properly control the necessary control volume and focus only on competitive profit pursuit, resulting in an actual reduction rate of only about 15-25%. In addition, it is difficult to even expect liquefaction of reduced livestock manure due to the excessive total nitrogen content.

In the case of general equipment currently in circulation, although it is configured to evaporate the moisture in the contents by utilizing the decomposition heat of organic matter due to microbial reaction, there is a problem that the internal temperature does not exceed a certain temperature and drops, resulting in a significantly reduced reduction rate, because the amount of air required for microbial reaction is not sufficiently supplied. Therefore, a method is adopted to intentionally generate bubbles using a jetter and forcefully disperse the bubbles using a bubble motor located at the top of the reactor to increase the reduction efficiency. However, the bubbles generated in this way act like a blanket, which can be effective in maintaining the temperature, but actually have the opposite effect in reducing the evaporation. This can be seen from the actual statistics that the reduction rate of such systems is only about 15-25%. In addition, there is a problem that the residue of livestock manure dispersed through the discharge port pollutes the atmosphere and the natural environment.

As a prior art patent for solving such problems, registered patent No. 10-039195 discloses an intake pump (12) installed and operated on a supply pipe (12a) through which manure received in a storage tank is supplied to a reaction tank (10); a jetter (20) installed on one side of the reaction tank (10) to stir the manure received; an air supply device (30) configured to supply air into the reaction tank (10), wherein an exhaust pipe (34) having a closed type is installed to equalize air pressure within the reaction tank (10), a blower (31) is installed in a branch pipe (33) installed to be connected to the exhaust pipe so as to be able to suck in and supply air in the atmosphere, a plurality of branch pipes (36) are installed to be connected at predetermined intervals to the exhaust pipe, and an acoustic resonance diffuser (35) is installed in each branch pipe so as to spray the transported air; In the reaction tank (10), a suction pipe (41) is installed so as to extend upward from the manure accommodated therein, and a pump (43) is installed on the suction pipe (41) to transport the manure, and a fluid detection sensor (42) is installed to stop the operation of the pump (43) if it does not detect movement of the contents for a certain period of time, and an injection nozzle (44) is mounted on the end of the suction pipe to spray the sucked contents, and a foam detection sensor (45) is installed on the upper part of one side of the reaction tank (10) to automatically operate the pump (43) only when foam is detected, so that a foam removal device (40) is installed to remove foam generated on the upper surface of the manure in the reaction tank (10); a temperature maintenance means (50) is installed in the reaction tank (10) to maintain the temperature inside the reaction tank (10) at a constant level; an extraction pump (16) is installed and operated on a discharge pipe (16a) to discharge the remaining manure after the reaction in the reaction tank (10); A livestock manure treatment system is disclosed, characterized by including a control means (60) that calculates, processes, and controls input/output signals. However, the registered patent has the disadvantage that the process is complicated and the cost required for the equipment and the management and operation costs are excessive.

As a prior art patent for solving such problems, Republic of Korea Patent No. 10-2348205 discloses a livestock waste treatment device including: a hopper for receiving livestock waste; a supply conveyor for transporting livestock waste in the hopper; a livestock waste reduction device for fermenting and drying the livestock waste supplied from the supply conveyor to reduce the waste; a heating means installed in the livestock waste reduction device to heat the livestock waste; a discharge conveyor for discharging livestock waste reduced in the livestock waste treatment device to the outside; and a purification means for purifying water vapor discharged from the livestock waste reduction device.

However, in the case of the above registered patent, as shown in (a) and (c) of FIG. 9, since a plurality of blades installed to stir livestock manure inside the livestock manure reducer are spaced apart from each other in the direction of the rotation axis, livestock manure is stuck to the spaced area between neighboring blades on the inner wall of the livestock manure reducer, and there is a problem that heat transfer to the inside is not performed due to the livestock manure stuck to the inner wall, thereby reducing the reduction performance. In addition, in order to remove the livestock manure stuck to the inner wall, there is an inconvenience that the reducer must be stopped and the manager must apply impact with an extension such as a shovel to detach it from the inner wall, and in the case where the discharge conveyor at the bottom is driven to discharge the detached livestock manure to the outside, there is a risk that the discharge port may be blocked or the conveyor, etc. may be damaged if there is a large lump of livestock manure.

Meanwhile, the above-mentioned Republic of Korea registered patent No. 10-2348205 mentions a method of connecting multiple livestock manure reduction devices in series or in parallel. However, when multiple livestock manure reduction devices or processors are installed to process a large amount of livestock manure, facilities and processes for connecting each livestock manure reduction device or processor and transporting the processed and discharged livestock manure must also be added, which significantly increases facility costs, complicates the treatment process, and significantly increases the installation space.

Hereinafter, preferred embodiments of the present invention will be described in detail.

In explaining the present invention, if it is judged that a specific description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. In addition, the terms described below are terms defined in consideration of the functions in the present invention, and these may vary depending on the intention of the user or operator, precedents, etc. Therefore, the definitions should be made based on the contents throughout this specification.

Referring to FIGS. 1 and 2, the livestock manure treatment device (100) according to the present invention can be largely configured to include a container body (110), a rotating means (150), and a conveying screw (170). Here, the livestock manure may be manure discharged from livestock such as cows, pigs, chickens, ducks, goats, and sheep.

The above container body (110) accommodates livestock manure. It may be formed by including a pair of inner space portions (120) on the left and right sides having a cross-section of a shape, in which a pair of discharge groove portions (125) are formed with a structure in which the lower portions on the left and right sides are convex downwards, an outer space portion (130) surrounding an outer surface of the pair of inner space portions (120) excluding a pair of discharge groove portions (125) and accommodating a first heat medium (131) and a first heater (133) as a heating means, and a pair of outer lower space portions (135) in contact with the outer space portions (130) and surrounding each discharge groove portion (125) and accommodating a second heat medium (136) and a second heater (138) as a heating means.

The above-mentioned rotation means may be configured to include a pair of first and second rotation axes (151a, 151b) installed on the left and right sides with respect to the center of the inner space (120), a pair of left and right rotation axes, a plurality of support members (155) installed along the circumferential direction and longitudinal direction of each rotation axle, and a plurality of blades (157) installed on the support members (155).

And, an exhaust port (113) is installed at the top of the container body (110), a drain port is installed at the bottom, and a first motor (151) and a second motor (171) for driving the rotation means (150) and the transfer screw (170) are installed on one side.

Referring to FIG. 3, since two rotation axes are installed in this embodiment, livestock manure can be stirred in various ways. As in (a) of FIG. 3, the first rotation axis (151a) on the left can rotate counterclockwise and the second rotation axis (151b) on the right can rotate clockwise. As in (b) of FIG. 3, the first rotation axis (151a) on the left can rotate clockwise and the second rotation axis (151b) on the right can rotate counterclockwise. As in (c) of FIG. 3, both the first rotation axis (151a) on the left and the second rotation axis on the right can rotate counterclockwise or both can rotate clockwise. In addition, the livestock manure stirring methods exemplified in FIGS. 3 (a) to (c) can be combined. For example, in the case where livestock manure reduction treatment is performed for 12 hours, it can be exemplified that rotation is controlled to occur in the manner of (c) of Fig. 3 for 4 hours, rotation is controlled to occur in the manner of (b) of Fig. 3 for the next 4 hours, and rotation is controlled to occur in the manner of (a) of Fig. 3 for the remaining 4 hours.

Meanwhile, referring to FIG. 4, according to another embodiment of the present invention, unlike the previously described embodiment, the container body (110) has an inner space portion. It has a cross-section of a shape and three discharge grooves (125) are formed, and the outer space (130) surrounds the outer surface of the inner space (120) except for the three discharge grooves (125) and accommodates a first heat medium (131) and a first heater (133) as heating means, and is configured to include three outer lower space parts (135) that surround each discharge groove part (125) and accommodate a second heat medium (136) and a second heater (138) as heating means. And the rotation means is configured to include three first, second, and third rotation axes (151a, 151b, 151c) installed respectively in the center and left and right sides of the inner space, a plurality of supporters (155) installed respectively along the circumferential direction and longitudinal direction of each rotation axle (151a, 151b, 151c), and a plurality of blades (157) installed on the supporters (155).

The above-mentioned transfer screw (170) is configured in a number corresponding to each rotation shaft (151a, 151b, 151c) and discharge groove (125).

The present invention may divide the container body and the inner space into a left and right pair as in the embodiments of FIGS. 1 to 3 and install two rotation axes, or divide them into three as in the embodiment of FIG. 4 and install three rotation axes.

The container body of this structure not only increases in volume, but also has the advantage of maximizing processing capacity and discharge speed compared to a single structure because the rotating shaft and blades installed in each compartment rotate to reduce material, and each transport screw can transport material individually.

Referring to FIG. 4 and FIG. 5 together, in this embodiment, the blades (157) coupled to the first and third rotation axes (151a, 151c) on the left and right may be arranged as ribbon-shaped blades (157), and the blade coupled to the second rotation axis (151b) in the center may be arranged as rod-shaped blades (157).

In addition, referring to FIG. 4 and FIG. 6 together, in this embodiment, the blades coupled to the left and right rotation axes as well as the blades coupled to the central rotation axes can be arranged as ribbon-shaped blades.

And the container body (110) may further include a control unit that measures the weight of livestock manure through a load cell and controls the heating temperature of the heater, heating time, and operation of the internal discharge conveyor until the livestock manure fed into the container body reaches a preset weight after reduction of livestock manure. The fed livestock manure may be decomposed or reduced through drying, and these two functions may be performed in combination. These functions are controlled through the control unit, and the properties or quality of the compost vary depending on the control method.

The above composting of livestock manure means that organic matter is decomposed by microorganisms and turned into compost, and at this time, the type of microorganism that acts is determined by the temperature. For example, mesophilic bacteria such as Bacillus genus bacteria and Aspergillus genus filamentous fungi and actinomycetes act specifically depending on the type of organic matter to carry out composting, and thermophilic bacteria such as Talaromyces thermophilus and Aspergillus candidus filamentous fungi and Bacillus coagulans bacterium can be exemplified.

For example, in the case of the above dry weight loss control, it can be achieved by heating livestock manure through a heater to generate steam and forcibly exhausting it to the outside.

Each discharge groove (125) is formed to extend from one side of the container body (110) to the other side along the direction of the rotation axis (153), and a discharge port (111) is installed on one side.

The present invention further includes an outer lower space (135) together with an outer space (130), and the outer lower space (135) is formed in each discharge groove (125).

More specifically, in Korean Patent No. 10-2348205, since it is composed only of an outer space and heating is performed only in the outer space, livestock manure accommodated in the discharge groove that accommodates the transport screw or the internal discharge conveyor is hardly dried by heating.

Accordingly, in the present invention, an outer lower space (135) surrounding a discharge groove (125) is installed, and a second heater (138) and a second heat medium (136), such as oil, are filled therein to heat the space, thereby improving drying performance.

However, it is preferable to control the first heater and the second heater to heat in the ranges of 100 to 190°C and 50 to 80°C, respectively.

The reason is that the first heater is intended to supply sufficient heat as the main heating means, so it heats at a relatively higher temperature than the second heater. However, in the case of the second heater, since heat is directly transferred to the metal material transfer screw, if expansion occurs due to high heat, the equipment may be damaged, so it is desirable to heat in the range of 50 to 80°C.

Meanwhile, although a conveying screw (170) is arranged in the discharge groove (125), livestock manure is deposited in the remaining space and is compressed to a high pressure due to the load of livestock manure filled on the upper side and the pressure when stirred by the rotating means. In this way, the livestock manure deposited in the discharge groove is not only in a state of being pressurized, but also hardly dried because no stirring occurs at all.

Therefore, in the present invention, it is more preferable to control the transport screw (170) to rotate in reverse as shown in Fig. 4 so that the livestock manure settled in the discharge groove (125) during the weight loss process is transported in the opposite direction of the discharge port (111) and mixed with the livestock manure received in the inner space (120) by the rotation means (150) while heating is performed in the outer lower space (135) surrounding the discharge groove (125).

However, since the amount of livestock manure settled in the discharge groove (125) is smaller than that of livestock manure accommodated in the inner space, it is desirable to set the time and interval for reverse rotation in advance through the control unit.

In addition, as described above, since the heating performance is improved through the combination of the configuration of heating in the outer lower space and reversely rotating the conveying screw, the width and height of the discharge groove can be configured to be larger than before, and by employing a conveying screw of a larger size than before, the processed livestock manure can be quickly discharged to the outside, which has the advantage of increasing the overall processing speed.

And when the reduction treatment of livestock manure is completed, the transport screw (170) is rotated forward to transport the livestock manure to the discharge outlet (111).

FIG. 9a is a drawing showing a state in which first and second supports having different lengths and four rows of ribbon-shaped blades are installed on a rotational axis of the present invention, and the four rows of ribbon-shaped blades are each installed with different waveforms based on the direction of the rotational axis, FIG. 9b is a drawing showing a state in which three rows of ribbon-shaped blades are installed on a rotational axis, unlike FIG. 9a, FIG. 9c is a drawing showing a state in which a ribbon-shaped blade and a rod-shaped blade are combined on a rotational axis, unlike FIGS. 9a and 9b, and FIG. 9d is a drawing corresponding to FIG. 9a showing a state in which four rows of ribbon-shaped blades are installed with two each forming the same waveform.

Referring to FIGS. 9A to 9D, the rotating means of the present invention may be configured to include a rotating shaft (153) installed horizontally within the container body (110), a plurality of supports (155) installed along the circumferential direction and longitudinal direction of the rotating shaft (153), and a plurality of blades (157) installed on the supports (155).

As shown in FIGS. 9a and 9b, the ribbon-shaped blades (157a) may be sequentially arranged in groups of three or four at regular intervals along the circumferential direction of the rotation axis (153).

Referring to FIG. 9a, when four ribbon-shaped blades are installed, the waveform of each ribbon-shaped blade is a structure that is shifted in parallel along the axial direction when compared to the waveform of the neighboring ribbon-shaped blade along the circumferential direction (clockwise), and the distance of the parallel shift can be exemplified as A/4 based on the distance (A) between a pair of first or second supports neighboring along the axial direction. That is, with respect to the ribbon-shaped blade (157a[1]) of the first row, the ribbon-shaped blade (157a[2]) of the second row moves in parallel by 1/4 A, and the ribbon-shaped blades (157a[3], 157a[4]) of the third and fourth rows move in parallel by 2/4 A and 3/4A, respectively.

Referring to FIG. 9b, when three ribbon-shaped blades are installed, the waveform of each ribbon-shaped blade is a structure that is translated in parallel along the axial direction when compared to the waveform of the neighboring ribbon-shaped blade along the circumferential direction, and the distance of the parallel translation can be exemplified as A/3 based on the distance (A) between a pair of first or second supports neighboring along the axial direction. That is, with respect to the ribbon-shaped blade (157a[1]) of the first row, the ribbon-shaped blade (157a[2]) of the second row translates in parallel by 1/3 A, and the ribbon-shaped blade (157a[3]) of the third row translates in parallel by 2/3 A.

In this way, when arranging multiple ribbon-shaped blades, if each ribbon-shaped blade is moved in parallel in the axial direction, the highest parts (crowns) of the waveforms do not overlap and are arranged continuously along the axial direction, which has the advantage of preventing livestock manure from sticking to the wall surface of the inner space.

In Korean Patent No. 10-2348205, since a plurality of blades are spaced apart from each other in the direction of the rotation axis, there was a problem that livestock manure was adhered to the spaced area between adjacent blades on the inner wall of the livestock manure reduction device, and heat transfer to the inside was not performed due to the livestock manure adhered to the inner wall, so that the reduction performance was deteriorated. However, in the present invention, a plurality of ribbon-shaped blades are employed, but the crests of the waveforms of each ribbon-shaped blade are arranged so as not to overlap each other, so that livestock manure is not adhered to the wall surface of the inner space, and thus the heat transfer performance supplied from the outer space is not deteriorated, so that efficient drying performance can be exhibited.

In addition, as shown in Fig. 9c, the above blades may be combined with the ribbon-shaped blade (157a) having a wave-shaped structure by repeatedly combining at each end of the first support (155a) and the second support (155b) that are alternately arranged, and the rod-shaped blade (157b) installed on one side of the first support (155a) or the second support (155b).

As described above, the ribbon-shaped blade (157a) prevents livestock manure from sticking by adjusting the gap so that the floor portion is adjacent to the inner space wall, and the rod-shaped blade (157b) arranged between the ribbon-shaped blade and the rotation shaft improves livestock manure stirring performance.

The present invention described above is merely exemplary, and those skilled in the art will readily appreciate that various modifications and equivalent other embodiments are possible therefrom. Therefore, it will be readily understood that the present invention is not limited to the forms mentioned in the detailed description above. Accordingly, the true technical protection scope of the present invention should be determined by the technical idea of the appended claims. In addition, the present invention should be understood to include all modifications, equivalents, and substitutes within the spirit and scope of the present invention defined by the appended claims.
