Abstract
Description
Technical Field
[0001] This utility model relates to the field of superior new breeds of livestock, poultry and aquatic products and healthy breeding technology, specifically a slanted screen solid-liquid separator with a primary screening and separation device. Background Technology
[0002] Inclined screen solid-liquid separators are widely used in the solid-liquid separation of agricultural waste (such as livestock and poultry manure), food processing waste, and papermaking sludge. The core principle is to use the filtering effect of the inclined screen to allow the liquid to pass through the screen and be discharged, while the solid material is intercepted on the screen surface and transported out, thus achieving preliminary dry-wet separation.
[0003] However, traditional inclined screen solid-liquid separators do not perform preliminary screening of the materials to be processed. The materials to be processed are often mixed with a large number of large particles (such as stones, unbroken hard blocks) and long fibrous materials (such as straw, hair, and strips of cloth). When these impurities and fibrous materials enter the fine inclined screen device, they can easily cause the screen to clog, entangle, and wear excessively. This not only forces the equipment to stop frequently for manual cleaning, which seriously reduces the processing efficiency and continuity, but also greatly shortens the service life of the core inclined screen device and increases maintenance costs. At the same time, the clogging problem also limits the overall processing capacity of the equipment and may lead to a high moisture content in the separated solid materials, affecting the subsequent storage, transportation, or resource utilization.
[0004] To address this, a slanted screen solid-liquid separator with a primary screening device was proposed. Utility Model Content
[0005] The purpose of this invention is to provide an inclined screen solid-liquid separator with a primary screening and separation device, which solves the technical problem that traditional devices do not perform preliminary screening of the materials to be processed, and achieves the purpose of preliminary screening and collection of the materials to be processed.

The extrusion rollers can facilitate further extrusion of the sieved material, the gear can facilitate one extrusion roller to drive the other extrusion roller to rotate, and the second servo motor can facilitate the rotation of the extrusion rollers.
[0010] Preferably, a guide plate is fixedly connected to the lower end of the inner wall of the discharge shell, and a discharge port is opened at the lower end of the outer wall of the rear end of the discharge shell. The guide plate facilitates the discharge of the screened and squeezed material, and the discharge port facilitates the discharge of the material.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0024] Example 1:
[0025] A preferred embodiment of the inclined screen solid-liquid separator with a primary screening device provided by this utility model is, for example... Figure 1-4As shown: A slanted screen type solid-liquid separator with a primary screening and separation device includes a machine body 1, a feed shell 2, a discharge shell 3, and a primary screening and separation component 4. The feed shell 2 is located at the upper end of the machine body 1, the discharge shell 3 is located at the lower end of the machine body 1, and the primary screening and separation component 4 is located on the feed shell 2. The primary screening and separation component 4 includes a primary screening plate 41, which is fixedly connected to the feed shell 2 by a connecting spring. A first vibration motor 42 is fixedly connected to the middle of the lower surface of the primary screening plate 41. A connecting block 43 is fixedly connected to the upper part of the outer wall of the front end of the feed shell 2. A sliding groove 44 is opened in the middle of the upper surface of the connecting block 43. A first servo motor 45 is fixedly connected to the middle of one side of the connecting block 43. A threaded rod 46 is fixedly connected to the output end of the first servo motor 45. A threaded sleeve 47 is sleeved on the outer side of the threaded rod 46 away from the first servo motor 45. A mounting frame 48 is fixedly connected to the upper surface of the threaded sleeve 47. A plurality of cleaning brushes 49 are provided on the lower surface of the mounting frame 48.
[0026] A first partition plate 410 is provided on the upper surface of the primary screening plate 41 near the first servo motor 45. The first partition plate 410 is fixedly connected to the feed shell 2. A collection box 411 is fixedly connected to the outer wall of the feed shell 2 near the first partition plate 410.
[0027] Furthermore, in this embodiment, the first vibration motor 42 drives the primary screening plate 41 to vibrate, thereby blocking large particles and long fibers in the material. Then, the first servo motor 45 drives the threaded rod 46 to rotate, and the threaded rod 46 drives the threaded sleeve 47 to move. The threaded sleeve 47 drives the cleaning brush 49 on the mounting frame 48 to collect the large particles and long fibers on the upper surface into the collection box 411 on one side. This removes large particles and long fibers from the material that are likely to cause blockage or entanglement in the subsequent inclined screen, protecting the subsequent fine inclined screen device from blockage, wear, or entanglement, ensuring that the inclined screen can operate stably and efficiently for a long time, while reducing the load on the inclined screen and improving the overall processing capacity.
[0028] Example 2:
[0029] Based on Embodiment 1, a preferred embodiment of the inclined screen type solid-liquid separator with a primary screening device provided by this utility model is, for example... Figure 1-4 As shown: Baffles 5 are fixedly connected to both sides of the upper surface of the machine body 1. A sieve plate 6 is fixedly connected to the middle of the baffle 5 through a connecting spring. Two second vibration motors 7 are fixedly connected to the middle of the lower surface of the sieve plate 6. A second partition plate 8 is fixedly connected to the upper end of the outer wall of the baffle 5 near the center of the machine body 1.
[0030] The discharge shell 3 has two rotatably connected extrusion rollers 9 inside. A gear 10 is fixedly connected to one side of the extrusion roller 9. A second servo motor 11 is fixedly connected to the outer wall of the discharge shell 3 away from the gear 10. The output end of the second servo motor 11 is fixedly connected to one side of the front extrusion roller 9.
[0031] A flow guide plate 12 is fixedly connected to the lower end of the inner wall of the discharge shell 3, and a discharge port 13 is opened at the lower end of the outer wall of the rear end of the discharge shell 3.
[0032] Multiple support legs 14 are fixedly connected to both sides of the lower surface of the machine body 1 and the feed shell 2. A drain valve 15 is provided at the lower part of the outer wall of the discharge shell 3 near the gear 10.
[0033] A control panel 16 is fixedly connected to the middle of the outer wall of one side of the support leg 14. The first vibration motor 42, the first servo motor 45, the second vibration motor 7, and the second servo motor 11 are all electrically connected to the control panel 16.
[0034] A connecting pipe 17 is fixedly connected to the outer wall near the lower end of the rear end of the feed housing 2. Multiple nozzles 18 are provided at the rear end of the connecting pipe 17, and a connecting hole 19 is provided in the middle of the upper surface of the connecting pipe 17.
[0035] Furthermore, in this embodiment, the second vibration motor 7 drives the sieve plate 6 to vibrate, separating the material into dry and wet components. Water is discharged from the drain valve 15, while the material on the upper surface is squeezed out by the second servo motor 11 driving the extrusion roller 9 to rotate. This not only effectively removes residual moisture from the material but also further compacts the material, facilitating subsequent processing and transportation.
[0036] In use, the material to be processed is placed on the upper surface of the primary screen plate 41. The primary screen plate 41 is vibrated by the first vibration motor 42, which can block large particles and long fibers in the material. Then, the threaded rod 46 is rotated by the first servo motor 45, and the threaded sleeve 47 is moved by the threaded rod 46. The threaded sleeve 47 drives the cleaning brush 49 on the mounting frame 48 to collect the large particles and long fibers on the upper surface into the collection box 411 on one side. This removes large particles and long fibers from the material that are easy to cause blockage or entanglement in the subsequent inclined screen, protects the subsequent fine inclined screen device, prevents blockage, wear or entanglement, ensures that the screen plate 6 can operate stably and efficiently for a long time, and reduces the load on the inclined screen and improves the overall processing capacity.
[0037] The sieved material falls onto the upper surface of the sieve plate 6. The second vibration motor 7 drives the sieve plate 6 to vibrate, separating the material into dry and wet components. The water flows into the discharge shell 3 and is discharged from the drain valve 15. The material on the upper surface of the sieve plate 6 falls between the extrusion rollers 9. The second servo motor 11 drives the front extrusion roller 9 to rotate, and then the gear 10 drives the rear extrusion roller 9 to rotate in the opposite direction, extruding the material and effectively removing residual moisture. This further compacts the material, facilitating subsequent processing and transportation. Finally, the material slides down from the guide plate 12 and is discharged from the outlet 13.
[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
