Description

Technical Field

[0001] This utility model belongs to the field of livestock manure fermentation technology, specifically relating to a livestock manure water treatment device based on microbial enhancement. Background Technology

[0002] Modern animal husbandry generates a lot of manure during the breeding process. Untreated manure is a major source of pollution in animal husbandry and urban life, producing foul odors that seriously affect the normal life and work of surrounding residents. In traditional technical solutions, microorganisms are often used for fermentation, which requires manual turning of the pile to allow oxygen to be exchanged within the manure. However, this turning process can easily produce foul odors, which can affect the health of operators and may increase the risk of infection. In addition, due to the limited efficiency of manual turning, uneven contact between microorganisms, manure pile, and oxygen is often produced. These problems need to be addressed. Utility Model Content

[0003] The purpose of this invention is to provide a microbial-enhanced livestock manure treatment device, which aims to solve the problem of poor working environment and low efficiency in the existing technology of manual turning of manure.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A microbial-enhanced livestock manure treatment device includes: a fermentation tank; a stirring mechanism comprising a drive unit and a telescopic assembly, the drive unit being mounted on the outer wall of the fermentation tank and its drive end being rotatably connected to the side wall of the fermentation tank; multiple telescopic assemblies being arranged horizontally at equal intervals along the rotation axis of the drive end, and their fixed ends being fixedly connected to the drive end; a squeezing mechanism being arranged opposite to the drive end and fixedly connected to the inner wall of the fermentation tank, capable of intermittently squeezing the telescopic assemblies in the horizontal direction to drive the telescopic parts of the telescopic assemblies to reciprocate in the horizontal direction; and multiple microbial carriers A, each of which has multiple through holes, and the multiple microbial carriers A being fixedly mounted on the telescopic parts of the multiple telescopic assemblies, with the direction of the through holes parallel to the direction of movement of the telescopic parts.

[0006] The beneficial effects of this utility model are as follows: By setting multiple through holes on the microbial carrier A, a large contact area between the microbial carrier A and the feces is ensured. The microbial carrier A is installed on the telescopic part of the telescopic component. As the drive end rotates, it plays a stirring role. At the same time, the telescopic part of the telescopic component intermittently reciprocates in the horizontal direction under the action of the extrusion mechanism. The microbial carrier reciprocates in the horizontal direction synchronously with the telescopic part of the telescopic component. During this process, the feces blocking the through holes can be shaken off, ensuring that the microbial carrier comes into contact with air and new feces.

[0007] Furthermore, each of the telescopic components includes a guide rod, a sliding sleeve, and an elastic reset member. The guide rod is horizontally arranged, and its first end is the fixed end. One end of the sliding sleeve is closed and slidably fitted onto the guide rod from its open end. One end of the elastic reset member is limited and abuts against the inner surface of the closed end of the sliding sleeve, and the other end is fixed to the second end of the guide rod. A plurality of bacterial carriers A are fixedly connected to the outer wall of the sliding sleeve, and the extrusion mechanism is driven and abuts against the closed end of the sliding sleeve.

[0008] A further beneficial effect of this utility model is that when the bacterial carrier A is installed on the sliding sleeve, the closed end of the sliding sleeve is squeezed by the squeezing mechanism, and slides along the guide rod, compressing the elastic reset member. When the closed end of the sliding sleeve is no longer subjected to the squeezing mechanism, the sliding sleeve makes a brief reciprocating motion along the guide rod under the action of the elastic reset member. During this process, the bacterial carrier A moves with the sliding sleeve, shaking off the feces in its through hole and re-exposing it to air. As the stirring mechanism runs, it re-exposes new feces and repeats this process.

[0009] Furthermore, the telescopic assembly also includes a limiting rod. The second end of the guide rod away from the driving end has a cavity and a through hole on its end face. The limiting rod is arranged parallel to the guide rod. One end passes through the through hole and is slidably connected to the end of the guide rod, and has a flange extending radially outward. The diameter of the flange is larger than that of the through hole. The other end abuts against the inner end face of the closed end of the sliding sleeve. The elastic reset member is a spring, which is sleeved on the outside of the limiting rod.

[0010] A further beneficial effect of this utility model is that the limiting rod prevents the sliding sleeve from displacing too far during the spring reset process, thus exceeding the original position of the sliding sleeve.

[0011] Furthermore, the stirring mechanism also includes a rotating support shaft and support rods. The rotating support shaft is arranged horizontally, with one end coaxially and fixedly connected to the drive end, and the other end rotatably connected to the inner side wall of the fermentation tank. The number of support rods corresponds one-to-one with the sliding sleeves, with one end hinged to the shaft of the rotating support shaft and the other end hinged to the outer side wall of the sliding sleeve.

[0012] A further beneficial effect of this utility model is that the support rod provides support for the sliding sleeve without affecting its normal sliding.

[0013] Furthermore, the extrusion mechanism includes a protrusion mounting plate and protrusions. The protrusion mounting plate is arranged opposite to the drive end. One side of the plate is fixedly connected to the inner wall of the fermentation tank, and the other side of the plate has an annular groove along the circumference. The closed ends of the plurality of sliding sleeves are slidably connected to the groove wall. There are a plurality of protrusions, which are equally spaced in the groove and fixedly connected to the bottom of the groove.

[0014] Further beneficial effects of this utility model are: by using the chute to regulate the rotation trajectory of the sliding sleeve, and by arranging protrusions at intervals in the chute, the frequency of multiple sliding sleeves on the rotating frame being squeezed by the protrusions is increased, thereby increasing the frequency of the sliding sleeve carrying the bacterial carrier reciprocating along the horizontal direction, enhancing the turning effect, and making the feces more evenly dispersed.

[0015] Furthermore, the protrusion has an inclined surface along the rotation direction of the driving end.

[0016] A further beneficial effect of this utility model is that by setting an inclined surface on the protrusion, the closed end of the sliding sleeve can be smoothly squeezed along the guide rod after contacting the protrusion.

[0017] Furthermore, it also includes a solid-liquid separation mechanism, which is installed in the middle of the fermentation tank and divides the fermentation tank into upper and lower parts, with the stirring mechanism located in the upper part of the fermentation tank.

[0018] Furthermore, the solid-liquid separation mechanism includes a support plate and a filter column. The support plate is inverted conical with an opening in the middle, and its outer periphery is fixedly connected to the middle of the inner wall of the fermentation tank. The filter column is hollow inside, and its lower end passes through the opening and is fixedly connected to the support plate. The side wall of the filter column is provided with a first-stage filter hole, and the lower end of the filter column is provided with a second-stage filter hole.

[0019] Further beneficial effects of this utility model are: by setting a solid-liquid separation mechanism to filter out the liquid part of the fecal-water mixture, the water content of the upper fecal part is reduced, which facilitates fermentation; the primary filter holes on the side of the filter column and the secondary filter holes at the bottom can prevent soft feces from falling down through the filter column.

[0020] Furthermore, it also includes floats and chains. There are multiple floats arranged in the lower part of the fermentation tank. There are multiple chains, one end of which is fixedly connected to the inner bottom wall of the fermentation tank, and the other end is fixedly connected to the outer wall of the floats. Multiple microbial carriers are installed at intervals along the length of each chain.

[0021] A further beneficial effect of this invention is that a float ball is set in the lower part of the fermentation tank in conjunction with the microbial carrier, so that the microbial carrier is evenly distributed in the manure water for fermentation.

[0022] Furthermore, it also includes an aeration mechanism, which includes an aeration pipe and an air pump. The aeration pipe is arranged on the bottom surface inside the fermentation tank, and the air pump is arranged on the outside of the fermentation tank, with its air outlet passing through the side wall of the fermentation tank and communicating with the main pipe of the aeration pipe.

[0023] A further beneficial effect of this invention is that it utilizes an aeration device to continuously introduce air into the lower half of the fermentation tank. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] As shown in the figure, a microbial-enhanced livestock manure treatment device includes: a fermentation tank 1, a stirring mechanism 2, a pressing mechanism 3, and a microbial carrier A4. The fermentation tank 1 is a cylindrical body with an opening at the top, which serves as the material inlet. A light-shielding cover (not shown in the figure) is installed at the top opening. The stirring mechanism 2 includes a drive unit 210, a turntable 212, and a telescopic component 220. The drive unit 210 includes a rotary motor 211 and a turntable 212. The housing of the rotary motor 211 is installed on the outer wall of the fermentation tank 1, and the turntable... 212 is coaxially and fixedly connected to the motor shaft of the rotary motor 211 and rotatably connected to the inner wall of the fermentation tank 1. There are six telescopic components 220, all horizontally arranged and distributed circumferentially along the turntable 212. The fixed ends are mounted on the surface of the turntable 212, forming a cage-like structure with an approximately cylindrical outline. The extrusion mechanism 3 is arranged relative to the turntable 212 and mounted on the inner wall of the fermentation tank 1. As the telescopic components 220 rotate with the turntable 212, the extrusion mechanism 3 can intermittently extrude force on the telescopic ends of the telescopic components 220. (The text abruptly ends here, likely due to an incomplete sentence or missing information.) Multiple carriers A4, each rectangular in shape with chamfered edges, are provided. Each carrier A4 has multiple through-holes. These carriers are evenly arranged on the outside of the telescopic components 220 and fixedly connected to them. They can move synchronously with the telescopic components 220, and the axial direction of their through-holes is parallel to the horizontal direction of movement of the telescopic components 220. Through this technical solution, the present invention achieves the following effects: by providing multiple through-holes on the carriers A4, a large contact area between the carriers A4 and the feces is ensured. The carriers A4 are installed on the telescopic components 220 and, with the rotation of the turntable 212, act as a stirrer. Simultaneously, the telescopic components 220 intermittently reciprocate horizontally under the action of the extrusion mechanism 3. The carriers A4 reciprocate horizontally synchronously with the telescopic components 220. During this process, the feces blocking the through-holes are shaken out, ensuring contact between the carriers A4 and air, and allowing them to come into contact with new feces.

[0036] In some embodiments, the telescopic assembly 220 includes a guide rod 221, a sliding sleeve 222, and an elastic reset member 223. The guide rod 221 is a long, straight, round rod arranged horizontally, with one end fixed to the outer periphery of the turntable 212. The sliding sleeve 222 is closed at one end, has a long, straight, rectangular shape, and an internal cavity adapted to the guide rod 221. It is slidably sleeved on the guide rod 221. The elastic reset member 223 is located inside the cavity of the sliding sleeve 222, with one end fixedly connected to the inner surface of the closed end of the sliding sleeve 222, and the other end fixedly connected to the free end of the guide rod 221. The bacterial carrier A4 is fixed on the outer wall of the sliding sleeve 222. The extrusion mechanism... 3. The outer side of the closed end of the intermittently squeezed sliding sleeve 222. Through the above technical solution, the technical effects that this utility model can achieve are as follows: the bacterial carrier A4 is installed on the sliding sleeve. When the closed end of the sliding sleeve is squeezed by the squeezing mechanism, it slides along the guide rod and compresses the elastic reset member. When the closed end of the sliding sleeve is no longer subjected to the squeezing mechanism, the sliding sleeve makes a brief reciprocating motion along the guide rod under the action of the elastic reset member. During this process, the bacterial carrier A4 moves with the sliding sleeve, shaking the feces in its through hole and re-exposing it to air. With the operation of the stirring mechanism, it re-exposes new feces and repeats this process.

[0037] In some embodiments, the telescopic assembly 220 further includes a limiting rod 224. The guide rod 221 has a cavity at the end away from the turntable 212 and a through hole is reserved on the corresponding end face. The limiting rod 224 is arranged horizontally, with one end passing through the through hole and slidably connected to the end of the guide rod 221. The end of the limiting rod 224 passing through the through hole has a flange extending radially outward, and the diameter of the flange is larger than that of the through hole. The other end of the limiting rod 224 abuts against the inner surface of the closed end of the sliding sleeve 222. The elastic reset member 223 is a spring, sleeved on the outside of the limiting rod 224. In the initial state, the flange at the end of the limiting rod 224 contacts the inner end face of the guide rod 221 but does not have pressure, and the spring is in a normal state. Through the above technical solution, this embodiment uses the limiting rod 224 to prevent the sliding sleeve 222 from displacing too far during the spring reset process, exceeding the original position of the sliding sleeve 222.

[0038] In some embodiments, the stirring mechanism further includes a rotating support shaft 230 and a support rod 240. The rotating support shaft 230 is horizontally arranged, with one end coaxially fixedly connected to the turntable 212 and rotating with the turntable 212, and the other end rotatably connected to the inner wall of the fermentation tank 1. The number of support rods 240 corresponds one-to-one with the sliding sleeves 222. Multiple sets of ear plates are respectively provided on the shaft of the rotating support shaft 230 and the outer wall of the sliding sleeve 222. One end of the support rod 240 is hinged to the ear plate on the shaft of the rotating support shaft 230, and the other end is hinged to the ear plate on the outer wall of the sliding sleeve 222. In the initial state, the support rod 240 is perpendicular to the rotating support shaft 230 and the sliding sleeve 222. When the sliding sleeve 222 slides back and forth under the action of the extrusion mechanism 3 and the spring, the support rod 240 is offset with the sliding sleeve 222 with the ear plate on the rotating support shaft 230 as the axis. Through the above technical solution, this embodiment can use the support rod 240 to support the sliding sleeve 222 without affecting the normal sliding of the sliding sleeve 222.

[0039] In some embodiments, the extrusion mechanism 3 includes a protrusion mounting plate 310 and protrusions 320. The protrusion mounting plate 310 is arranged relative to the motor shaft of the rotary motor. One side of the plate is fixedly connected to the inner wall of the fermentation tank 1, and the other side of the plate is provided with an annular groove 311 along the circumference. The closed ends of multiple sliding sleeves 220 are inserted into the groove 311 and rotate along the groove 311. There are multiple protrusions 320, the number of which is the same as the number of sliding sleeves 222. The multiple protrusions 320 are arranged at equal intervals in the groove 311 and are fixedly connected to the bottom of the groove 311. Through the above technical solution, this embodiment uses the groove 311 to regulate the rotation trajectory of the sliding sleeves 222 and arranges the protrusions 320 at intervals in the groove 311 to increase the frequency of the multiple sliding sleeves 222 being extruded, thereby increasing the frequency of the sliding sleeves 222 and the bacterial carrier A4 reciprocating in the horizontal direction, enhancing the turning effect, and making the feces more evenly dispersed.

[0040] Based on the previous embodiment, the protrusion 320 is provided with an inclined surface along the rotation direction of the turntable 212, and the cross section of the protrusion 320 in the vertical direction is approximately trapezoidal. Through the above technical solution, the inclined surface is provided on the protrusion 320, so that the closed end of the sliding sleeve 222 can be smoothly squeezed along the guide rod 221 after contacting the protrusion 320.

[0041] In some embodiments, the inner wall of the open end of the sliding sleeve 222 is provided with an internal spline, and the outer wall of the guide rod 221 near the turntable 212 is provided with an external spline that matches the internal spline and is keyed to the open end of the sliding sleeve 222. Through the above technical solution, the technical effects achieved by this embodiment are: the meshing effect between the splines can be used to clean the feces adhering between the sliding sleeve 222 and the guide rod 221 during the sliding process of the sliding sleeve 222.

[0042] In some embodiments, a solid-liquid separation mechanism 5 is also included. The solid-liquid separation mechanism 5 is installed in the middle of the fermentation tank 1, dividing the fermentation tank 1 into upper and lower parts. The stirring mechanism 2 is located in the upper part of the fermentation tank 1. The solid-liquid separation mechanism 5 includes a support plate 510 and a filter column 520. The support plate 510 is inverted conical with an opening in the middle and its outer periphery is fixedly connected to the middle of the inner wall of the fermentation tank 1. The filter column 520 is hollow inside, with its lower end passing through the opening, and the column body is fixedly connected to the support plate 510. The side wall of the filter column 520 is provided with a primary filter hole 521, and the lower end of the filter column 520 is provided with a second-stage filter hole 522. In particular, the aperture of the second-stage filter hole 522 is smaller than that of the primary filter hole 521. Through the above technical solution, the technical effects that this embodiment can achieve are as follows: by setting the solid-liquid separation mechanism 5 to filter out the liquid part of the fecal-water mixture, the water content of the upper fecal part is reduced, which facilitates fermentation. The primary filter hole 521 on the side of the filter column 520 and the secondary filter hole 522 at the bottom can prevent soft feces from falling down through the filter column 520.

[0043] Based on the previous embodiment, the system further includes floats 6, chains 7, and microbial carriers B8. Multiple floats 6 are arranged in the lower part of the fermentation tank 1. Multiple chains 7 are attached, one end of which is fixedly connected to the inner bottom wall of the fermentation tank 1, and the other end is fixedly connected to the outer wall of the floats 6. Microbial carriers B8 are installed at intervals along the length of each chain 7. Through the above technical solution, the technical effects achieved by this embodiment are: by setting floats 6 in conjunction with microbial carriers B8 in the lower part of the fermentation tank 1, the microbial carriers B8 are evenly distributed in the manure water for fermentation.

[0044] In some embodiments, an aeration mechanism is also included, comprising an aeration pipe 9 and an air pump 10. The aeration pipe 9 is disposed on the bottom surface of the fermentation tank 1, and the air pump 10 is disposed on the outside of the fermentation tank 1, with its outlet end passing through the side wall of the fermentation tank 1 and communicating with the main pipe of the aeration pipe 9. Through the above technical solution, the technical effects achieved by this embodiment are: continuously supplying air to the lower half of the fermentation tank 1 using the aeration device.
