Description

Technical Field

[0001] This utility model relates to the field of animal husbandry technology, specifically to a solid-liquid separation device for animal husbandry manure. Background Technology

[0002] Livestock farming refers to the production activities of artificially raising and breeding livestock and poultry (such as pigs, cattle, sheep, chickens, ducks, etc.) to obtain products such as meat, eggs, milk, and fur. It is an important part of agriculture. Solid-liquid separation of livestock manure is a key link in the resource utilization and pollution control of manure. It separates the solid and liquid parts of manure through physical, mechanical, or chemical methods so that they can be processed and utilized separately. This process can reduce the difficulty of manure treatment and improve resource recovery efficiency. Mechanical separation is mainly divided into screw extrusion separators, inclined screen separators, and centrifugal separators.

[0003] Centrifugal separators utilize the centrifugal force generated by high-speed rotation to separate solids and liquids with different densities. When sewage enters the high-speed rotating separation cylinder, due to the density difference between solid particles and liquid, under the action of centrifugal force, the denser solid particles are thrown towards the cylinder wall, forming a sediment layer; the less dense liquid accumulates in the central area and is discharged through a special outlet.

[0004] While existing separation devices offer numerous advantages during use, they still suffer from several drawbacks. Their ability to clean the filter pores is inadequate. When solid particles are thrown against the cylinder wall, the loss of moisture causes them to clump together, and some solid material can clog the inner wall of the filter pores, making cleaning the separation cylinder difficult for operators. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a solid-liquid separation device for livestock manure.

[0006] The technical solution adopted by this utility model to solve its technical problem is a solid-liquid separation device for livestock breeding manure, including a shell, a cover plate and a separation cylinder. The cover plate is screwed to the upper outer wall of the shell, and a fixing ring is provided at the lower end of the cover plate. The fixing ring is located inside the shell, and a support bearing is interference-fitted to the inner wall of the fixing ring. The separation cylinder is interference-fitted to the inner ring of the support bearing. Vibration motors are screwed to both sides of the upper outer wall of the fixing ring. The outer wall of the separation cylinder has a circular array of filter holes, and the filter holes are opened at an inclined angle.

[0007] By adopting the above technical solution, the drive motor can drive the separation cylinder to rotate circumferentially inside the fixed ring via the linkage shaft and the support bearing. The support bearing maintains the position of the separation cylinder, ensuring the stability of the rotational position of the separation cylinder inside the shell. After the separation cylinder centrifuges and stops, the vibration generated by the vibrating motor will drive the fixed ring and the separation cylinder to vibrate synchronously through the shock absorber, preventing the vibration from being transmitted to the shell and the cover plate. The vibration of the separation cylinder will disperse and detach the solids attached to the inner wall of the separation cylinder, and the vibration will drive the solids blocked inside the filter holes to fall off, so that the separated solids are concentrated at the top of the sealing plate, which is convenient for the staff to collect the solids and improve the efficiency of solids recycling.

[0008] Specifically, a drain pipe is welded to one side of the lower end of the outer wall of the outer shell, and a feed pipe is welded to one side of the upper outer wall of the cover plate. Both the drain pipe and the feed pipe are connected to the inside of the outer shell.

[0009] By adopting the above technical solution, the sewage can enter the separation cylinder through the feed pipe, and the sewage can be collected through the separation cylinder. The separation cylinder is driven by the drive motor to rotate and centrifuge the sewage. The separated liquid can be thrown into the area between the outer shell and the separation cylinder. The liquid gathers at the bottom of the inner shell due to gravity and can be discharged through the drain pipe.

[0010] Specifically, the upper outer wall of the fixing ring is screwed with shock absorbers arranged in a circular array, and the upper outer wall of the shock absorbers is screwed to the lower outer wall of the cover plate.

[0011] By adopting the above technical solution, the vibration motor will generate high-frequency vibration when it is working. The shock absorber can buffer the transmission of vibration to the cover plate and the outer shell, thereby reducing the overall noise of the device.

[0012] Specifically, a drive motor is screwed to the upper end of the cover plate, a support frame is screwed to the upper end of the inner wall of the separator, a linkage shaft is screwed to the upper end of the support frame, and the linkage shaft is connected to the output end of the drive motor by a coupling.

[0013] By adopting the above technical solution, the drive motor is connected to the linkage shaft through a coupling, which has high transmission efficiency and can ensure that the separation cylinder obtains a stable speed. In addition, the coupling itself has a shock absorption function, which can prevent the transmission of the amplitude of the vibration of the separation cylinder to the drive motor and ensure the stable operation of the drive motor.

[0014] Specifically, a guide plate is welded to the lower end of the outer wall of the separator cylinder. The diameter of the guide plate is larger than the inner diameter of the opening at the lower end of the outer shell. The lower outer wall of the separator cylinder adopts a conical shape design, and the lower end of the separator cylinder is located inside the opening at the lower end of the outer shell.

[0015] By adopting the above technical solution, the guide plate can block the opening at the lower end of the shell and guide the liquid on the outer wall of the separation cylinder, ensuring that the liquid is concentrated and gathered at the lower end of the shell, preventing the liquid from flowing out through the opening at the lower end of the shell. In addition, the conical structure can guide the solids to gather at the bottom, which is convenient for the subsequent centralized collection of solids.

[0016] Specifically, a sealing plate is provided at the lower end of the separation cylinder, and a sealing ring is bonded to the outer wall of the sealing plate. The sealing ring is in contact with the inner wall of the separation cylinder. A fixing frame is welded to the lower end of the sealing plate, and the fixing frame is screwed to the outer wall of the lower end of the separation cylinder.

[0017] By adopting the above technical solution, the sealing plate can seal the lower end of the separation cylinder through the sealing ring, ensuring that the sewage is fully subjected to centrifugal and vibration effects inside the separation cylinder, and ensuring thorough separation; when slag discharge is required, the sealing plate can be opened by removing the screws of the fixing frame.

[0018] The beneficial effects of this utility model are:

[0019] The solid-liquid separation device for livestock manure described in this utility model uses vibration of the separation cylinder to disperse and detach the solids attached to the inner wall of the separation cylinder, and the vibration also drives the solids blocking the filter holes to fall off, so that the separated solids are concentrated at the upper end of the sealing plate, which makes it easier for workers to collect the solids and improves the efficiency of solids recycling.

[0020] The livestock manure solid-liquid separation device of this utility model has a guide plate that can block the opening at the lower end of the outer shell and guide the liquid on the outer wall of the separation cylinder, ensuring that the liquid is concentrated at the lower end of the inner shell and ensuring the integrity of the liquid recovery.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the livestock manure solid-liquid separation device of this utility model includes a shell 1, a cover plate 2, and a separation cylinder 3. The cover plate 2 is screwed to the upper outer wall of the shell 1. A fixing ring 22 is provided at the lower end of the cover plate 2. The fixing ring 22 is located inside the shell 1. A support bearing 23 is interference-fitted to the inner wall of the fixing ring 22. The separation cylinder 3 is interference-fitted to the inner ring of the support bearing 23. Vibration motors 25 are screwed to both sides of the upper outer wall of the fixing ring 22. The outer wall of the separation cylinder 3 has a circular array of filter holes 33, which are opened at an inclined angle.

[0030] During use, the drive motor can drive the separation cylinder 3 to rotate circumferentially inside the fixed ring 22 via the support bearing 23 through the linkage shaft 32. The support bearing 23 maintains the position of the separation cylinder 3, ensuring the stability of the rotational position of the separation cylinder 3 inside the outer shell 1. After the separation cylinder 3 centrifuges and stops, the vibration generated by the vibrating motor 25 will drive the fixed ring 22 and the separation cylinder 3 to vibrate synchronously through the shock absorber 24, and prevent the vibration from being transmitted to the outer shell 1 and the cover plate 2. The vibration of the separation cylinder 3 will cause the solids attached to the inner wall of the separation cylinder 3 to disperse and detach, and the vibration will drive the solids blocked inside the filter holes 33 to fall off, so that the separated solids are concentrated at the top of the sealing plate 35, which is convenient for the staff to collect the solids and improve the efficiency of the solids recycling.

[0031] For example, for feeding and discharging materials, such as Figure 1 As shown, a drain pipe 11 is welded to one side of the lower end of the outer wall of the outer shell 1, and a feed pipe 21 is welded to one side of the upper end of the outer wall of the cover plate 2. Both the drain pipe 11 and the feed pipe 21 are connected to the inside of the outer shell 1.

[0032] In use, the sewage can enter the separation cylinder 3 through the feed pipe 21. The sewage is collected through the separation cylinder 3. The separation cylinder 3 is driven by the drive motor to rotate and centrifuge the sewage. The separated liquid can be thrown into the area between the outer shell 1 and the separation cylinder 3. The liquid gathers at the bottom of the inner shell 1 due to gravity and can be discharged through the drain pipe 11.

[0033] To control the vibration range, for example, such as Figure 3 As shown, the upper outer wall of the fixing ring 22 is screwed with shock absorbers 24 arranged in a circular array, and the upper outer wall of the shock absorbers 24 is screwed to the lower outer wall of the cover plate 2.

[0034] When in use, the vibration motor 25 will generate high-frequency vibration. The shock absorber 24 can buffer the transmission of vibration to the cover plate 2 and the outer shell 1, thereby reducing the overall noise of the device.

[0035] To drive rotation, for example, such as Figure 3 As shown, a drive motor is screwed to the upper end of the cover plate 2, and a support frame 31 is screwed to the upper end of the inner wall of the separator 3. A linkage shaft 32 is screwed to the upper end of the support frame 31, and a coupling is used to connect the linkage shaft 32 to the output end of the drive motor.

[0036] During use, the drive motor is connected to the linkage shaft 32 via a coupling, which has high transmission efficiency and can ensure that the separation cylinder 3 obtains a stable speed. In addition, the coupling itself has a shock absorption function, which can prevent the transmission of the amplitude of the vibration of the separation cylinder 3 to the drive motor and ensure the stable operation of the drive motor.

[0037] For example, to facilitate liquid flow, such as Figure 5 As shown, a guide plate 34 is welded to the lower end of the outer wall of the separator 3. The diameter of the guide plate 34 is larger than the inner diameter of the lower opening of the outer shell 1. The lower outer wall of the separator 3 adopts a conical shape design, and the lower end of the separator 3 is located inside the lower opening of the outer shell 1.

[0038] When in use, the guide plate 34 can block the opening at the lower end of the outer shell 1 and guide the liquid on the outer wall of the separation cylinder 3, ensuring that the liquid is concentrated at the lower end of the inner shell 1, preventing the liquid from flowing out through the opening at the lower end of the outer shell 1. The conical structure can guide the solids to gather at the bottom, which is convenient for the subsequent centralized collection of the solids.

[0039] To ensure a tight seal, for example, such as Figure 4 As shown, a sealing plate 35 is provided at the lower end of the interior of the separation cylinder 3. A sealing ring is bonded and fixed to the outer wall of the sealing plate 35. The sealing ring is in contact with the inner wall of the separation cylinder 3. A fixing frame 36 is welded to the lower end of the sealing plate 35. The fixing frame 36 is screwed to the lower outer wall of the separation cylinder 3.

[0040] When in use, the sealing plate 35 can seal the lower end of the separation cylinder 3 through the sealing ring, ensuring that the feces and sludge are fully subjected to centrifugal and vibration effects in the separation cylinder 3, and ensuring thorough separation; when sludge discharge is required, the sealing plate 35 can be opened by removing the screws of the fixing bracket 36.

[0041] In use, the manure to be treated is conveyed through the feed pipe 21 on one side of the upper outer wall of the cover plate 2. The manure enters the separation cylinder 3 through the feed pipe 21. The drive motor at the upper end of the cover plate 2 is started. The drive motor is connected to the linkage shaft 32 through the coupling and transmits power to the linkage shaft 32. The linkage shaft 32 then drives the separation cylinder 3 to rotate through the support frame 31.

[0042] During the rotation of the separator 3, the internal fecal matter is centrifuged and separated. The separated liquid is thrown into the area between the outer shell 1 and the separator 3, while the solid matter adheres to the inner wall of the separator 3.

[0043] The liquid that enters the area between the outer shell 1 and the separation cylinder 3 will gather at the bottom of the inner side of the outer shell 1 due to gravity. The gathered liquid can be discharged through the drain pipe 11 on the lower side of the outer wall of the outer shell 1.

[0044] After centrifugation is completed and the machine is stopped, the vibration motors 25 on both sides of the upper outer wall of the fixed ring 22 are started. The vibration generated by the vibration motors 25 drives the fixed ring 22 and the separation cylinder 3 to vibrate synchronously through the shock absorber 24. The vibration of the separation cylinder 3 causes the solids attached to its inner wall to disperse and detach, and at the same time drives the solids blocked inside the filter holes 33 to fall off, so that the solids are concentrated and gathered at the upper end of the sealing plate 35.

[0045] After the vibration cleaning is completed, the staff removes the screws of the fixing frame 36, opens the sealing plate 35, and collects the solids that have gathered at the top of the sealing plate 35.
