Description

[0002] In recent years, with the rapid development of China's livestock and poultry breeding industry towards scale and intensification, the total amount of excrement generated by farms on a daily basis has increased significantly. If such excrement is directly discharged without effective treatment, it is easy to cause soil heavy metal exceeding standards, water body eutrophication and air odor pollution, which not only destroys the ecological environment, but also may affect human health through the food chain. Therefore, harmless treatment and resource utilization of livestock and poultry excrement has become one of the core needs for sustainable development of the breeding industry, and relevant treatment technologies are widely used in the excrement end-of-pipe treatment link of large-scale farms and the raw material pretreatment process of organic fertilizer production enterprises.

[0003] To solve the problem of excrement treatment, the existing extrusion type dry-wet separation equipment has become one of the mainstream treatment equipment due to its compact structure, simple operation, high separation efficiency and controllable cost. Such equipment usually transports excrement through a screw conveyor and realizes solid-liquid separation by the extrusion action of the filter cartridge and the screw. The solid residue separated can be further processed into organic fertilizer raw materials to realize resource recovery; the liquid separated can be used for irrigation of farmland or discharged after reaching the standard through subsequent processes such as anaerobic fermentation and biochemical treatment, so as to realize the reduction and resource utilization of excrement.

[0004] However, in the long-term continuous operation process of the existing extrusion type dry-wet separation equipment, the coarse fibers, impurity particles and other substances contained in the excrement are easy to adhere to the surface of the filter cartridge and gradually accumulate during the extrusion process, resulting in filter cartridge blockage, so that the liquid cannot pass through the filter cartridge smoothly, reducing the solid-liquid separation efficiency and affecting the discharge quality.

Moreover, the first feature "above", "over" and "on" the second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature.

[0022] As Figures 1 to 8As shown, the livestock and poultry manure comprehensive treatment system provided by the embodiment of the application comprises a manure dry-wet separation device. The manure dry-wet separation device is used for dry-wet separation of manure and other materials, and comprises a rack 110, a machine box 120, an auger assembly and a cleaning assembly. The rack 110 serves as a mounting base for other components including the machine box 120. The other components can be directly or indirectly mounted on the rack 110 to form a relatively integral whole. The machine box 120 is fixedly connected to the rack 110. The machine box 120 is provided with a feeding port 122 for conveying materials and a discharging port 123 for discharging materials. A material treatment cavity 121 is formed in the machine box 120 for accommodating materials.

[0023] A filter cartridge 210 is arranged in the material treatment cavity 121. The filter cartridge 210 is fixedly connected to the machine box 120. The inside of the filter cartridge 210 and the machine box 120 jointly form a solid-liquid separation cavity 211. One end of the solid-liquid separation cavity 211 is in communication with the feeding port 122, and the other end is in communication with the discharging port 123. The auger assembly comprises a rotating shaft 220 and an auger blade 221. The rotating shaft 220 is rotatably arranged in the solid-liquid separation cavity 211 and coaxially arranged in the inside of the filter cartridge 210. The rotating shaft 220 can rotate around its own axis. The auger blade 221 is spirally arranged around the central axis of the rotating shaft 220 and fixed to the outer wall of the rotating shaft 220. The auger blade 221 rotates synchronously with the rotating shaft 220 to continuously push and compress the materials. Further, the manure dry-wet separation device further comprises a pressing plate 212 and a hydraulic cylinder. The pressing plate 212 is arranged close to the discharging port 123. The hydraulic cylinder is fixedly arranged on the machine box 120. The output end of the hydraulic cylinder is fixedly connected to the pressing plate 212 to fix the position of the pressing plate 212, so that the pressing plate 212 has a certain gap with the discharging port 123.

[0024] Specifically, before the materials are put in, the rotating shaft 220 rotates around its own axis and drives the auger blade 221 to rotate synchronously. Then the materials are put into the solid-liquid separation cavity 211 from the feeding port 122. Under the action of the auger blade 221, the materials continuously advance towards the discharging port 123. As the materials are continuously conveyed to the discharging end, the front is blocked by the pressing plate 212, causing the materials to gradually accumulate and be subjected to high extrusion pressure between the discharging port 123 and the pressing plate 212 and in the area close to the discharging port 123 of the rotating shaft 220. Under the action of the high extrusion pressure, the liquid in the materials is forced to be extruded and discharged from the device through the filter cartridge 210. The remaining solid residues are pushed out from the gap between the pressing plate 212 and the discharging port 123 under the action of the continuous pushing force, completing the solid residue discharge and thus completing the solid-liquid separation operation. During the solid-liquid separation process, when the filter cartridge 210 is blocked, the cleaning assembly can spray the extruded liquid in the materials to the surface of the filter cartridge 210, thereby flushing the filter cartridge 210 and effectively relieving the blockage of the filter cartridge 210.

[0025] In one of the embodiments, a plurality of liquid outlet holes 223 are formed on the auger blade 221 near the discharge port 123 area, the liquid outlet holes 223 are arranged on the edge of the auger blade 221, and the openings of the liquid outlet holes 223 are directed to the surface of the filter cartridge 210; a plurality of liquid inlet holes 222 are formed on the rotating shaft 220 near the discharge port 123 area, and the liquid inlet holes 222 are arranged in a circumferential direction around the central axis of the rotating shaft 220. The rotating shaft 220 is fixedly provided with a blocking cylinder 231 inside, and the blocking cylinder 231 is coaxially and gapingly arranged with the rotating shaft 220. The blocking cylinder 231 and the rotating shaft 220 jointly form a containing cavity 241 for containing the liquid squeezed out from the material. The liquid outlet holes 223 and the liquid inlet holes 222 are both in communication with the containing cavity 241.

[0026] Further, the cleaning assembly includes a pneumatic unit, a reset unit, and a push rod 234. The pneumatic unit is used to periodically provide power for the push rod 234 to drive the push rod 234 to slide along the axis of the push rod 234, and the push rod 234 is coaxially arranged inside the blocking cylinder 231. It can be understood that the pneumatic unit drives the push rod 234 to slide at a constant power at a preset time interval.

[0027] Specifically, during the solid-liquid separation process, when the pneumatic unit is started, the push rod 234 is driven to slide to the left, i.e. Figure 8 the left and right directions, so that the area of the containing cavity 241 is increased, thereby enabling the liquid squeezed out from the material to be sucked into the containing cavity 241 through the liquid inlet holes 222. When the filter cartridge 210 is severely blocked, a large amount of liquid cannot be discharged in time through the filter cartridge 210 and accumulates in the solid-liquid separation cavity 211, and thus when the push rod 234 slides to the left, more liquid will be sucked into the containing cavity 241 through the liquid inlet holes 222. When the pneumatic unit stops providing power, the reset unit drives the push rod 234 to slide to the right to reset, the area of the containing cavity 241 is reduced, the liquid in the containing cavity 241 is pushed by the push rod 234, and the surface of the liquid inlet holes 222 is covered with material, so that the liquid is forced to be sprayed out through the liquid outlet holes 223. Since the liquid outlet holes 223 are located on the auger blade 221 near the inner surface of the filter cartridge 210, the liquid squeezed out from the liquid outlet holes 223 directly flushes the filter cartridge 210, effectively relieving the blockage of the filter cartridge 210. Further, one-way valves are arranged in the liquid inlet holes 222 and the liquid outlet holes 223. The one-way valve of the liquid inlet hole 222 only allows the liquid to flow from the solid-liquid separation cavity 211 to the containing cavity 241 in one direction, and the one-way valve of the liquid outlet hole 223 only allows the liquid to be sprayed out from the containing cavity 241 to the surface of the filter cartridge 210.

[0028] When the filter cartridge 210 is not severely clogged, most of the liquid can still be discharged normally through the filter cartridge 210, with only a portion of the liquid seeping out from the material and entering the receiving cavity 241. At this time, the push rod 234's reset process still pushes this portion of liquid out through the liquid outlet 223 and discharges it out of the equipment again through the filter cartridge 210. This process is equivalent to adding an auxiliary drainage path along the inside of the rotating shaft 220 for recirculation and discharge on the basis of the original filter cartridge 210 filtration area, indirectly expanding the effective liquid outlet area and helping to improve the solid-liquid separation efficiency.

[0029] In one embodiment, the pneumatic unit includes a first support shaft 232, a second support shaft 233, and an external air extraction system. The first and second support shafts 232 and 233 are coaxially sleeved together and both are fixedly connected to the housing 120. The second support shaft 233 is coaxially rotatably disposed at one end of the rotating shaft 220 near the discharge port 123. Both the first and second support shafts 232 and 233 are coaxially slidably connected to the push rod 234. An air extraction chamber 243 is formed inside the first and second support shafts 232. The push rod 234, the baffle 231, and the second support shaft 233 together form a sealed cavity 242. The sealed cavity 242, the air extraction chamber 243, and the receiving cavity 241 are all isolated from each other. The external air extraction system is used to extract air from the air extraction chamber 243 to drive the push rod 234 to slide along its own axial direction. Specifically, the push rod 234 is coaxially provided with a sliding sealing ring at the end of the air extraction chamber 243. The sliding sealing ring is slidably engaged with the first support shaft 232 and the second support shaft 233 to ensure the airtightness of the air extraction chamber 243.

[0030] Furthermore, the reset unit includes a tension spring 235. One end of the tension spring 235 is fixedly connected to the push rod 234, and the other end is fixedly connected to the second support shaft 233. The elastic force of the tension spring 235 always causes the push rod 234 to tend to slide away from the first support shaft 232.

[0031] Specifically, the external air extraction system periodically extracts air from the air extraction chamber 243 to drive the push rod 234 to slide to the left along its own axis. Figure 8 In the left-right direction, the tension spring 235 is stretched, increasing the area of ​​the receiving cavity 241, thereby drawing the liquid squeezed out from the material into the receiving cavity 241 through the liquid inlet 222. When the external suction system stops working, the tension spring 235 gradually returns to its original position, causing the push rod 234 to slide to the right along its own axis, reducing the area of ​​the receiving cavity 241, and forcing the liquid in the receiving cavity 241 to be ejected from the liquid outlet 223 on the auger blade 221.

[0032] In particular, the rotation shaft 220 and the auger blade 221 will have a high temperature after a long time of working, and the liquid entering the containing cavity 241 can cool the rotation shaft 220. When the liquid in the containing cavity 241 is discharged from the liquid outlet hole 223, the auger blade 221 can be cooled, thereby effectively prolonging the service life of the components.

[0033] In one of the embodiments, the feces and urine dry-wet separation device further comprises a driving mechanism 300, which is used to drive the rotation shaft 220 to rotate around its own axis.

[0034] Further, the driving mechanism 300 comprises a third support shaft 303, a motor 301 and a shaft coupling 302. The third support shaft 303 is rotationally connected with the cabinet 120, and the third support shaft 303 is coaxially fixedly arranged at one end of the rotation shaft 220 close to the feeding port 122. The shaft coupling 302 is connected with the third support shaft 303 and the motor 301. Therefore, the motor 301 provides power for the third support shaft 303 through the shaft coupling 302, thereby driving the rotation shaft 220 to rotate around its own axis.

[0035] In one of the embodiments, the liquid outlet hole 223 is inclined, and the inclined direction is at an angle with the tangent direction of the auger blade 221. Specifically, when the liquid in the containing cavity 241 is sprayed at high speed from the inclined liquid outlet hole 223 under the action of pressure, the liquid spraying will generate an auxiliary pushing force on the auger blade 221 in the same direction as the rotation direction of the auger blade 221, thereby further promoting the rotation of the auger blade 221 and the rotation shaft 220 in the normal rotation direction, thereby effectively reducing the load of the motor 301, playing a role of partial self-driving, and reducing energy consumption. It can be understood that the more the filter cartridge 210 is blocked, the more the liquid entering the containing cavity 241, the higher the spraying pressure, and the speed and flow of the sprayed liquid also increase, thereby generating a stronger auxiliary pushing force, and further relieving the blockage of the filter cartridge 210.

[0036] In one of the embodiments, the feces and urine dry-wet separation device further comprises a waste water tank 130, which is used to collect the liquid filtered by the filter cartridge 210.

[0037] The embodiment of the present application also provides a comprehensive treatment method for livestock and poultry feces, which is used to execute the comprehensive treatment system for livestock and poultry feces in any one of the above embodiments, and comprises the following working steps: S100, starting the motor 301 to drive the rotation shaft 220 to rotate around its own axis and drive the auger blade 221 to rotate synchronously.

[0038] S200, feeding the material into the solid-liquid separation cavity 211 from the feeding port 122, and the auger blade 221 pushes the material to the discharge port 123 to perform solid-liquid separation.

[0039] S210, under the continuous pushing force of the auger blade 221, the material is extruded in the gap between the pressing plate 212 and the discharge port 123, realizing solid-liquid separation.

[0040] S220, the liquid is filtered through the filter cartridge 210 and collected in the wastewater tank 130; the solid residue is discharged from the gap between the pressing plate 212 and the discharge port 123.

[0041] S300, the external suction system periodically drives the push rod 234 to slide leftward along its own axis, i.e. Figure 8 the left-right direction in the figure, the liquid squeezed out of the material is sucked into the containing cavity 241 through the liquid inlet hole 222 on the rotating shaft 220 (synchronized with S200-S220).

[0042] S310, when the filter cartridge 210 is seriously clogged, more liquid is sucked into the containing cavity 241; when the clogging is light, the amount of liquid sucked is reduced.

[0043] S320, the external suction system stops working, the tension spring 235 returns to its original length, driving the push rod 234 to slide rightward to reset, i.e. Figure 8 the left-right direction in the figure, the liquid in the containing cavity 241 is pushed out through the liquid outlet hole 223 on the auger blade 221, flushing the filter cartridge 210, thereby effectively solving the problem of clogging of the filter cartridge 210.

[0044] The technical features of the above embodiments can be combined arbitrarily, and to make the description concise, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present application.

[0045] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as limiting the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
