Technical Field

[0001] This utility model relates to the technical field of solid-liquid separation equipment, specifically a solid-liquid separation device for alfalfa fermentation. Background Technology

[0002] Alfalfa is a high-quality forage resource. After fermentation, its nutritional value and palatability are further enhanced, making it widely used in animal husbandry. However, the product obtained after alfalfa fermentation is a solid-liquid mixture, which requires solid-liquid separation for subsequent processing and utilization.

[0003] Currently, commonly used solid-liquid separation equipment such as plate and frame filter presses and horizontal screw centrifuges can achieve solid-liquid separation to a certain extent, but some liquid will still remain in the alfalfa fermentation product, making it difficult to completely separate without applying external pressure.

[0004] Therefore, this utility model provides a solid-liquid separation device for alfalfa fermentation to solve the above problems. Utility Model Content

[0012] By adopting the above technical solution, power is provided to drive the funnel cylinder to rotate and generate centrifugal force.

[0013] Furthermore, a handle is fixedly connected to the outer wall of the top cover.

[0014] By adopting the above technical solution, it is easy to open and operate the top cover.

[0015] Furthermore, a reinforcing ring is fixedly connected to the outer wall of the conical cover.

[0017] Beneficial effects

[0018] This invention provides a solid-liquid separation device for alfalfa fermentation. Compared with the prior art, it has the following advantages:

[0019] 1. When the alfalfa fermentation solid-liquid separation equipment is running, open the top cover and put the material into the filter cylinder. After closing, start the servo motor, which drives the filter cylinder to rotate at high speed through the transmission rod and support column. Use centrifugal force to throw out the liquid. After stopping the rotation, start the hydraulic rod to press down the pressure plate to further press the material and improve the dehydration rate.

During operation, the base support column supports the filter cylinder, the auxiliary support restricts the deformation of the cylinder, and the pressure plate reinforcing ribs enhance its stress strength.

[0020] 2. The solid-liquid separation equipment for alfalfa fermentation has a handle for easy opening and operation of the top cover.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Reference Figures 1 to 4This application provides a solid-liquid separation device for alfalfa fermentation, including a support rod 1. A pressing assembly 2 is mounted on the top of the support rod 1. The pressing assembly 2 includes a mounting frame 21, which is fixedly connected to the top of the support rod 1. A material cylinder 22 is fixedly connected to the inner wall of the mounting frame 21. A top cover 23 is movably connected to the top of the material cylinder 22. A hydraulic rod 24 is fixedly installed inside the top cover 23. A pressure plate 25 is fixedly connected to the movable end of the hydraulic rod 24. An auxiliary support 27 is fixedly connected to the inner wall of the material cylinder 22. A funnel 28 is rotatably connected to the inner walls of the two auxiliary supports 27. A reinforcing rib 26 is fixedly connected to the top of the pressure plate 25, and one side of the reinforcing rib 26 is fixedly connected to the movable end of the hydraulic rod 24. A conical cover 211 is fixedly connected to the bottom of the material cylinder 22. A base 210 is fixedly connected to the inner wall of the conical cover 211. A support column 29 is rotatably connected to the top of the base 210, and one end of the support column 29 is fixedly connected to the bottom of the funnel 28. The pressing assembly 2 also includes an annular collection box 213, with a central cylinder 214 fixedly connected to the top of the annular collection box 213, and a conical sleeve 215 fixedly connected to the top of the central cylinder 214. The pressing assembly 2 also includes a servo motor 217, with a transmission rod 216 fixedly connected to the output shaft of the servo motor 217. One end of the transmission rod 216 is fixedly connected to one end of the support column 29, and the transmission rod 216 is rotatably connected to the inside of the side wall of the conical sleeve 215.

[0030] In practice: The fermentation material requiring solid-liquid separation is placed into the sieve cylinder 28 by opening the top cover 23. Then, the top cover 23 is closed, and the servo motor 217 is activated, driving the transmission rod 216 to rotate. The transmission rod 216 then drives the support column 29 to rotate, which in turn drives the sieve cylinder 28 to rotate rapidly, generating centrifugal force to throw out the liquid from the sieve cylinder 28. After a period of time, the servo motor 217 is turned off to stop the sieve cylinder 28 from rotating. Then, the hydraulic rod 24 is activated to drive the pressure plate 25 downwards, thus separating the liquid from the liquid inside the sieve cylinder 28. The material is pressed to completely squeeze out any residual liquid, thereby improving the dehydration rate. The liquid then falls from the outlet of the conical cover 211 onto the surface of the conical sleeve 215. Since the surface of the conical sleeve 215 is curved, the liquid will slide into the annular collection box 213 for collection. At the same time as the hydraulic rod 24 is activated, the support column 29 on the base 210 will support the sluice cylinder 28. The auxiliary support 27 will also restrict the cylinder body of the sluice cylinder 28 to effectively prevent deformation of the sluice cylinder 28. The reinforcing ribs 26 on the pressure plate 25 are also used to improve the overall stress strength of the pressure plate 25.

[0031] Reference Figures 1 to 4 In one aspect of this embodiment, a handle 218 is fixedly connected to the outer wall of the top cover 23. A reinforcing ring 212 is fixedly connected to the outer wall of the conical cover 211.

[0032] In practice: the handle 218 makes it easy to open and operate the top cover 23. As the hydraulic rod 24 is pressed down, its pressure will be transmitted to the conical cover 211 through the funnel 28, support 29, and base 210. The reinforcing ring 212 can encircle the conical cover 211 to improve its strength and prevent deformation.

[0033] All electrical devices in this plan are powered by an external power source.

[0034] Working principle: During the solid-liquid separation of fermentation materials, the top cover 23 is first opened via handle 218, and the material is fed into the sieve cylinder 28. The top cover is then closed. The servo motor 217 is started, and its power is transmitted via transmission rod 216, driving the support column 29 to rotate the sieve cylinder 28 at high speed. Under centrifugal force, the liquid in the material is quickly ejected. Once the centrifugation process is complete, the servo motor 217 is turned off, stopping the rotation of the sieve cylinder 28.

[0035] At this time, the hydraulic rod 24 is activated, which drives the pressure plate 25 to apply downward pressure, deeply squeezing the material in the sieve cylinder 28 to ensure that the residual liquid is fully squeezed out, significantly improving the dewatering efficiency. The separated liquid slides down the outlet of the conical cover 211 to the curved surface of the conical sleeve 215, and finally collects in the annular collection box 213;

[0036] During the downward pressing operation of the hydraulic rod 24, the support column 29 on the base 210 provides stable support for the sluice cylinder 28, the auxiliary support 27 effectively limits the deformation of the sluice cylinder 28 wall, and the reinforcing ribs 26 on the surface of the pressure plate 25 further enhance its compressive strength. The pressure generated during the entire pressing process is transmitted layer by layer to the conical cover 211 through the sluice cylinder 28, support column 29, and base 210. The reinforcing ring 212 reinforces the conical cover 211 by surrounding it, ensuring the structural stability of the conical cover 211 and ensuring the safe and reliable operation of the equipment.
