Description

Technical Field

[0001] This application relates to the field of feed processing equipment, specifically a liquid feed sludge removal filter. Background Technology

[0002] Liquid feed production often involves impurities such as fibers and particles. Existing filters mostly use a single-layer filter structure, which suffers from low filtration efficiency, easy clogging, and difficult cleaning. Although some equipment is equipped with multi-layer filters, the accumulation of residue requires shutdown for cleaning, affecting continuous production. Therefore, there is an urgent need for a liquid feed residue removal device with high filtration efficiency and easy maintenance. Utility Model Content

[0003] The purpose of this utility model is to provide a liquid feed slag removal filter to solve the problems of uneven grinding effect, difficulty in controlling fineness, and the need for subsequent screening before utilization in existing traditional feed grinders. To achieve the above objective, this application provides the following technical solution: a liquid feed slag removal filter, comprising:

[0004] The cylinder has a cover at the top, which has a feed inlet and a bearing hole. The bottom of the cylinder is a hemispherical structure with a discharge outlet at the bottom.

[0005] A screen cylinder is disposed below the feed inlet. The screen cylinder has a cylindrical structure and is densely covered with screen holes around its perimeter.

[0006] A flow-cutting plate is disposed inside the cylinder and above the hemispherical structure. The flow-cutting plate is adapted to the inner wall of the cylinder. Multiple flow-guiding columns are evenly distributed on the flow-cutting plate. The flow-guiding columns penetrate the flow-cutting plate. Each flow-guiding column is provided with a cap above it. The cap is densely covered with flow-guiding holes.

[0007] A rotating shaft is disposed in the bearing hole, one end of which is connected to the first motor, and the other end is connected to the stirring mechanism via a connecting rod;

[0008] The stirring mechanism includes a U-shaped rod and an arc-shaped plate disposed on the U-shaped rod;

[0009] A central drive shaft passes through the hemispherical structure and the baffle plate and is disposed inside the cylinder. A stirring blade is coupled to the central drive shaft. The central drive shaft is connected to a second motor, which drives the stirring blade to rotate.

[0010] In a preferred embodiment of this technical solution, the U-shaped rods are symmetrically arranged inside the cylinder.

[0011] In a preferred embodiment of this technical solution, the U-shaped rod includes two symmetrically arranged vertical rods and a horizontal rod connecting the two vertical rods. The arc-shaped plates are arranged in pairs, with one end of each arc-shaped plate connected to the upper end of the vertical rod and the other end connected to the lower end of the other vertical rod, forming a spiral shape.

[0012] In a preferred embodiment of this technical solution, the center of the orthographic projection of the arc-shaped plate coincides with the center of the cylinder.

[0013] In a preferred embodiment of this technical solution, the stirring blade has a spiral structure, and the spiral angle of the stirring blade is 20°-30°.

[0016] In a preferred embodiment of this technical solution, the gap between the edge of the arc-shaped plate and the inner wall of the cylinder is 5-10mm.

[0017] In a preferred embodiment, the present technical solution further includes an observation hole, which is disposed on the side wall of the cylinder.

[0018] The preferred embodiment of this technical solution, compared with the prior art, has the following beneficial effects:

[0019] This invention utilizes a multi-stage filtration structure consisting of a sieve cylinder, a flow interceptor, and guide columns to progressively separate impurities from liquid feed. The sieve cylinder initially filters out large particles, while the guide columns and caps on the flow interceptor further refine the filtration, ensuring the uniformity and fineness of the liquid feed meet requirements and avoiding the uneven filtration problems of traditional equipment. A dual stirring mechanism—comprising a rotating shaft, a stirring mechanism, and a central drive shaft—is employed. A first motor drives the stirring mechanism for initial mixing of the liquid feed, while a second motor drives the stirring blades for secondary crushing and stirring of residual material. This ensures the continuity and efficiency of the filtration process, reducing manual intervention and downtime. Attached Figure Description

[0028] In order to solve the technical problems in the background art, such as Figure 1-3 As shown, this application provides a technical solution: a liquid feed slag removal filter, characterized as follows:

[0029] The cylinder 1 is a vertically positioned cylindrical container with a removable cover 2 at the top. The cover 2 has an inlet 3 and a bearing hole 4. The inlet 3 is used to inject the liquid feed to be filtered, and the bearing hole 4 is used to install the rotating shaft 13. The bottom of the cylinder 1 is a hemispherical structure 5, with an outlet 6 at the center of the bottom for discharging the filtered liquid feed. A screen cylinder 7 is located below the inlet 3. The screen cylinder 7 is a cylindrical structure with densely packed screen holes 8 on its sidewalls. The diameter of the screen holes 8 is determined according to the feed slag removal requirements, generally 5-20mm. The screen cylinder 7 can be directly connected to the flange at the inlet 3 or to the cover 2. A baffle plate 9 is horizontally positioned inside the cylinder 1, above the hemispherical structure 5. The outer edge of the baffle plate 9 is tightly fitted against the inner wall of the cylinder 1 to prevent the liquid feed from bypassing the baffle plate 9. Multiple guide columns 10 are evenly distributed on the intercepting plate 9, penetrating the intercepting plate 9. Each guide column 10 is topped with a cap 11. The cap 11 is densely covered with guide holes 12, which are used to further filter fine impurities in the liquid feed. A rotating shaft 13 is vertically installed in the bearing hole 4. One end of the rotating shaft 13 is connected to the first motor 14, and the other end is connected to the stirring mechanism 16 via a connecting rod 15. The stirring mechanism 16 includes a U-shaped rod 17 and an arc-shaped plate 18 installed on the U-shaped rod 17. A central drive shaft 19 is vertically installed inside the cylinder 1. The central drive shaft 19 passes through the hemispherical structure 5 and the intercepting plate 9, and is connected to the second motor 21. A stirring blade 20 is coupled to the central drive shaft 19. The second motor 21 drives the stirring blade 20 to rotate, performing secondary crushing and stirring of residual residue in the liquid feed to prevent residue accumulation.

[0030] In operation, liquid feed enters the screen cylinder 7 through the inlet 3, undergoes preliminary filtration through the screen holes 8, and then flows into the upper area of ​​the intercepting plate 9. Guided by the guide column 10 and the cap 11, the liquid feed is further filtered, with fine impurities trapped above the cap 11. The filtered liquid feed flows through the guide holes 12 into the hemispherical structure 5 area and is finally discharged from the outlet 6. Simultaneously, the first motor 14 drives the stirring mechanism 16 to rotate, performing preliminary mixing of the liquid feed; the second motor 21 drives the stirring blades 20 to rotate, further crushing and stirring the remaining residue, ensuring the continuity and efficiency of the filtration process.

[0031] Furthermore, the U-shaped rod 17 has a symmetrical U-shaped structure. The symmetrical arrangement of the U-shaped rod 17 allows the stirring mechanism 16 to distribute the stirring force evenly when rotating, avoiding eddies or dead zones in the liquid feed inside the cylinder 1. At the same time, the symmetrically arranged arc-shaped plates 18 can perform bidirectional stirring of the liquid feed, further improving filtration efficiency and uniformity.

[0032] Furthermore, the U-shaped rod 17 consists of two vertically arranged vertical rods 21 and a horizontally arranged horizontal rod 22. The two vertical rods 21 are symmetrically fixed to the connecting rod 15 at the lower end of the rotating shaft 13, and the horizontal rod 22 connects the lower ends of the two vertical rods 21, forming a U-shaped structure. The length of the vertical rods 21 matches the height of the cylinder 1 at the top of the hemispherical structure 5, and the length of the horizontal rod 22 is slightly smaller than the inner diameter of the cylinder 1 to ensure that the U-shaped rod 17 will not collide with the inner wall of the cylinder 1 when rotating. The arc-shaped plates 18 are arranged in pairs, with one end of each arc-shaped plate 18 connected to the upper end of one vertical rod 21 and the other end connected to the lower end of the other vertical rod 21, forming a spiral structure. The spiral arrangement of the arc-shaped plates 18 enables the stirring mechanism 16 to generate a spiral liquid flow when rotating, guiding the liquid feed from the upper part to the lower part of the cylinder 1, while stirring the residue in the liquid feed to prevent the residue from accumulating at the bottom of the cylinder 1. The spiral structure also improves the mixing uniformity of the liquid feed and ensures the filtration effect.

[0033] Furthermore, the orthographic projection of the arc-shaped plate 18 is an arc, with its center coinciding with the center of the cylinder 1. This ensures that the arc-shaped plate 18 can evenly distribute the stirring force during rotation, preventing eddies or dead zones from forming in the liquid feed within the cylinder 1. The design of the arc-shaped plate 18's orthographic projection center coinciding with the center of the cylinder 1 allows the arc-shaped plate 18 to maintain a uniform gap with the inner wall of the cylinder 1 during rotation, ensuring a stable flow of the liquid feed within the cylinder 1. Simultaneously, this design also improves the working efficiency of the stirring mechanism 16 and reduces energy consumption.

[0034] Furthermore, the stirring blade 20 is fixed to the central drive shaft 19 and has a helical structure. The helix angle of the stirring blade 20 is 20°-30°, preferably 25°, to ensure that the stirring blade 20 can generate sufficient axial thrust when rotating, pushing the secondary crushed liquid feed towards the discharge port 6. The helical structure and helix angle design of the stirring blade 20 enable it to generate a combined axial and radial motion when rotating, effectively stirring the residue in the liquid feed and preventing residue from accumulating at the bottom of the cylinder 1. At the same time, the helix angle design also improves the working efficiency of the stirring blade 20 and reduces energy consumption.

[0035] Furthermore, multiple sets of stirring blades 20 are evenly arranged along the axial direction of the central drive shaft 19. A certain distance is maintained between each set of stirring blades 20 to ensure that the stirring blades 20 can cover the entire axial range of the cylinder 1. Each set of stirring blades 20 includes two helical blades to ensure that the stirring force is evenly distributed when the stirring blades 20 rotate, avoiding eddies or dead zones in the liquid feed within the cylinder 1. The design of multiple sets of stirring blades 20 evenly arranged along the axial direction of the central drive shaft 19 allows the stirring blades 20 to perform multi-stage stirring of the liquid feed when rotating, ensuring uniform flow of the liquid feed during the filtration process.

[0036] Furthermore, the bearing sleeve 23 is located in the middle of the crossbar 22 and rotates with the crossbar 22. The central drive shaft 19 is located inside the bearing sleeve 23. The bearing sleeve 23 serves to support and stabilize the central drive shaft 19 and reduce its frictional resistance during rotation, thereby ensuring the stable operation of the stirring blade 20.

[0037] Furthermore, the gap between the edge of the arc-shaped plate 18 and the inner wall of the cylinder 1 is 5-10 mm, preferably 8 mm, to ensure that the arc-shaped plate 18 can effectively stir the liquid feed without rubbing against the inner wall of the cylinder 1 when rotating. When the first motor 14 drives the rotating shaft 13 to rotate, the U-shaped rod 17 and the arc-shaped plate 18 rotate accordingly. The gap between the edge of the arc-shaped plate 18 and the inner wall of the cylinder 1 is 5-10 mm, which allows the arc-shaped plate 18 to evenly stir the liquid feed when rotating, guiding the liquid feed to flow from the upper part to the lower part of the cylinder 1, while stirring the residue in the liquid feed to prevent the residue from accumulating at the bottom of the cylinder 1.

[0038] Furthermore, the observation port 24 is a circular opening located in the middle of the side wall of the cylinder 1. A flange is provided around the edge of the observation port 24, and a transparent cover is installed on the flange. The transparent cover is made of a corrosion-resistant and high-temperature-resistant transparent material, such as tempered glass or polycarbonate, to allow observation of the filtration status inside the cylinder 1. The observation port 24, located on the side wall of the cylinder 1, allows operators to observe the flow of liquid feed and the accumulation of residue inside the cylinder 1 in real time, enabling timely adjustment of equipment operating parameters or maintenance.

[0039] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
