Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to a flat plate centrifuge that facilitates slag discharge. Background Technology

[0002] Solid-liquid separation is a common operation in industrial production, and plate centrifuges, as an important solid-liquid separation device, are widely used in many industries such as chemical, pharmaceutical, and food processing. They achieve efficient separation of the solid and liquid phases in a mixture through centrifugal force generated by high-speed rotation, playing a crucial role in improving production efficiency and ensuring product quality.

[0003] In conventional flat-plate centrifuges, a motor typically drives a drum to rotate at high speed, causing solid-liquid separation of the material inside the drum under centrifugal force. Denser solid particles are thrown against the drum wall, forming a filter cake layer, while the less dense liquid flows out of the drum through the filter cake layer and small holes in the drum wall. For sludge removal, the filter cake is usually cleaned and discharged from the drum manually or using simple mechanical devices such as scrapers after the machine is stopped.

[0004] However, existing flat-plate centrifuges have a significant problem: they struggle to adapt to impurity layers of varying thicknesses. In actual production, due to differences in material properties and manufacturing processes, the thickness of the impurity layer entering the centrifuge is often not constant. When the impurity layer thickness changes, existing centrifuges cannot automatically adjust, resulting in uneven distribution of impurities within the drum. Thicker impurity layers concentrate in localized areas, which not only affects the uniformity of the centrifugal force field, significantly reducing the solid-liquid separation effect, but also adversely affects the high-speed rotation of the drum, increasing equipment instability and, in severe cases, even damaging the equipment. This greatly reduces the practicality and reliability of the flat-plate centrifuge. Therefore, a flat-plate centrifuge with easy slag discharge is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a flat-plate centrifuge that facilitates slag discharge, aiming to improve the existing technology's inability to adapt to impurity layers of varying thicknesses, resulting in uneven distribution of impurities within the drum. Thicker impurity layers concentrate in localized areas, affecting the uniformity of the centrifugal force field.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flat-plate centrifuge for easy slag discharge includes a support, a base plate fixedly connected to the top of the support, a support plate fixedly connected to the outer wall of the base plate, a sealing cover rotatably connected to the top of the base plate, a rotating feed column fixedly connected inside the sealing cover, a reaction vessel fixedly connected to the top of the base plate, an opening and closing assembly provided on the top of the base plate, and a rotating assembly provided on the top of the sealing cover.

[0008] The rotating assembly includes a first support block, the bottom of which is fixedly connected to the top of the sealing cover. A second hydraulic cylinder is rotatably connected to the inner wall of the first support block. A third connecting block is fixedly connected to the output end of the second hydraulic cylinder. A second rotating plate is rotatably connected to the inner wall of the third connecting block. A connecting column is fixedly connected to the side wall of the second rotating plate. A collar is rotatably connected to the outer wall of the connecting column. The outer wall of the collar is fixedly connected to the inside of the sealing cover.

[0009] As a further description of the above technical solution:

[0010] The opening and closing assembly includes a first connecting block, the bottom of which is fixedly connected to the top of the base plate. A first hydraulic cylinder is rotatably connected inside the first connecting block. A second connecting block is fixedly connected to the output end of the first hydraulic cylinder. A first rotating plate is rotatably connected to the side wall of the second connecting block. A limit block is fixedly connected to the bottom of the first rotating plate. The bottom of the limit block is fixedly connected to the top of the support plate. The bottom of the first rotating plate is fixedly connected to the top of the sealing cover.

[0011] As a further description of the above technical solution:

[0012] One end of the connecting column is fixedly connected to a first fixing block, a hollow block is fixedly connected to the side wall of the first fixing block, and a fixing column is slidably connected to the inner wall of the hollow block.

[0013] As a further description of the above technical solution:

[0014] A scraper is fixedly connected to one end of the fixed column, and the side wall of the scraper is slidably connected to the inner wall of the filter screen.

[0015] As a further description of the above technical solution:

[0016] The side wall of the fixed column is provided with a first spring, one end of which is fixedly connected to one end of the fixed column, and the other end of which is fixedly connected to the inside of the hollow block.

[0017] As a further description of the above technical solution:

[0018] A transmission structure is fixedly connected to the bottom of the base plate, a transmission shaft is fixedly connected to one side of the transmission structure, and a second fixing block is fixedly connected to the side wall of the transmission shaft.

[0019] As a further description of the above technical solution:

[0020] The top of the second fixed block is fixedly connected to a second support block, and the inner wall of the second support block is rotatably connected to a third rotating plate, and the inside of the third rotating plate is rotatably connected to a bolt.

[0021] As a further description of the above technical solution:

[0022] The outer wall of the bolt is threaded into the inside of the second fixing block, and a pressing column is fixedly connected to the bottom of the third rotating plate. The outer wall of the pressing column is set inside the filter screen.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the third connecting block is driven to move by the second hydraulic cylinder. During the movement of the third connecting block, the second rotating plate on the inner wall will rotate. During the rotation of the second rotating plate, the connecting column will rotate. This achieves the effect of adapting to impurity layers of different thicknesses. It solves the problem that the centrifuge cannot adapt to impurity layers of different thicknesses, which will cause the impurities to be unevenly distributed in the drum. Thicker impurity layers are concentrated in local areas, affecting the uniformity of the centrifugal force field. This improves the practicality of the flat plate centrifuge.

[0025] 2. In this invention, rotating the bolt causes it to rotate inside the second fixed block. After the bolt disengages from the third rotating plate, the third rotating plate can be moved to disengage the pressing column from the filter screen, achieving rapid disassembly of the filter screen and thus rapid slag discharge. This solves the problem that the inability to quickly disassemble the filter screen means it is difficult to thoroughly remove residual impurities after each use. Over time, residual impurities accumulate, causing the filter screen pores to shrink, increasing filtration resistance, and further reducing slag discharge efficiency. This invention improves the stability of the plate centrifuge. Attached Figure Description

[0039] Reference Figures 5-8 One end of the connecting column 16 is fixedly connected to a first fixing block 21. A hollow block 20 is fixedly connected to the side wall of the first fixing block 21. A fixing column 19 is slidably connected to the inner wall of the hollow block 20. The scraper 18, in conjunction with the fixing column 19 and the first spring 22, performs adaptive telescopic movement to achieve a scraping effect that adapts to impurity layers of different thicknesses. One end of the fixing column 19 is fixedly connected to the scraper 18. The scraper 18 is slidably connected to the hollow block 20 through the fixing column 19. The first spring 22 keeps the scraper 18 in contact with the inner wall of the filter screen 23. The contact pressure can be adaptively adjusted according to the thickness of the impurity layer to evenly remove attached impurities and avoid residue. The side wall of the scraper 18 is slidably connected to the inner wall of the filter screen 23. The filter screen 23 is made of corrosion-resistant and high-strength materials such as stainless steel wire mesh or porous metal plate. It is used to intercept impurities and allow liquid to pass through. This is existing technology and will not be described in detail here. The side wall of the fixing column 19 is provided with a first spring 22. One end of the first spring 22 is fixedly connected to one end of the fixed column 19, and the other end of the first spring 22 is fixedly connected to the inside of the hollow block 20. The bottom of the base plate 2 is fixedly connected to the transmission structure 11. The transmission structure 11 is fixedly connected to one side of the transmission shaft 24.

The inner wall of the second support block 26 is rotatably connected to the third rotating plate 27. The inside of the third rotating plate 27 is rotatably connected to the bolt 28. After rotating the bolt 28 to disengage it from the third rotating plate 27, the third rotating plate 27 rotates around the second support block 26, causing the pressing column 29 to disengage from the filter screen 23, releasing the fixation of the filter screen 23, realizing quick disassembly, and facilitating thorough cleaning of residual impurities. The outer wall of the bolt 28 is threadedly connected to the inside of the second fixed block 25. The bottom of the third rotating plate 27 is fixedly connected to the pressing column 29, and the outer wall of the pressing column 29 is set inside the filter screen 23.

[0040] Reference Figure 1 and Figure 2The opening and closing assembly includes a first connecting block 4, the bottom of which is fixedly connected to the top of the base plate 2. A first hydraulic cylinder 5 is rotatably connected inside the first connecting block 4. When the first hydraulic cylinder 5 extends or retracts, it pushes the second connecting block 6 to move horizontally, causing the first rotating plate 7 to rotate around the first connecting block 4, thereby realizing the opening and closing of the sealing cover 9. The rotation angle is limited by the limiting block 8 and the support plate 3 to ensure stable opening and closing. The output end of the first hydraulic cylinder 5 is fixedly connected to the second connecting block 6. The side wall of the second connecting block 6 is rotatably connected to the first rotating plate 7. The bottom of the first rotating plate 7 is fixedly connected to the limiting block 8, the bottom of which is fixedly connected to the top of the support plate 3. The bottom of the first rotating plate 7 is fixedly connected to the top of the sealing cover 9.

[0041] Working principle: When this flat-plate centrifuge, which facilitates slag discharge, is in operation, the base plate 2, which is fixedly connected to the top of the support 1, serves as the basic load-bearing component. The support plate 3 on the outer wall of the base plate 2 provides auxiliary support. The top of the base plate 2 is connected to the opening and closing assembly to achieve the rotational opening and closing of the sealing cover 9. The first connecting block 4 in the opening and closing assembly is fixed to the top of the base plate 2. When the first hydraulic cylinder 5, which is rotatably connected inside, extends or retracts, it pushes the second connecting block 6 to move horizontally, thereby driving the first rotating plate 7, which is rotatably connected to the second connecting block 6, to rotate around the first connecting block 4. The sealing cover 9 is fixed at the bottom of the first rotating plate 7 and connected to the limiting block 8. The limiting block 8 cooperates with the support plate 3 to limit the rotation angle of the sealing cover 9, ensuring its stable opening and closing. After the sealing cover 9 is closed, the rotating feed column 10 sends the material into the reaction vessel 30. The transmission structure 11 at the bottom of the base plate 2 drives the transmission shaft 24, which drives the filter screen 23 to rotate at high speed for solid-liquid separation. Impurities adhere to the inner wall of the filter screen 23 to form an impurity layer.

[0042] When impurities need to be cleaned, the rotating assembly at the top of the sealing cover 9 is activated, the first support block 12 is fixed at the top of the sealing cover 9, the second hydraulic cylinder 13 connected to the inner wall extends and retracts, pushing the third connecting block 14 to move, the third connecting block 14 drives the second rotating plate 15 connected to the inner wall to rotate, the second rotating plate 15 then drives the connecting column 16 to rotate around the collar 17, the first fixing block 21 at one end of the connecting column 16 drives the hollow block 20 to rotate, the fixing column 19 slidably connected inside the hollow block 20, under the action of the first spring 22, makes the scraper 18 always stick to the inner wall of the filter screen 23, which can be adaptively adjusted according to the thickness of the impurity layer to clean impurities evenly;

[0043] During slag discharge, the bolt 28 is rotated to disengage it from the third rotating plate 27. The third rotating plate 27 rotates around the second support block 26, causing the bottom pressing column 29 to disengage from the filter screen 23, thus enabling the quick disassembly of the filter screen 23 and facilitating the thorough removal of residual impurities. The entire process, through the coordinated operation of various components, improves the slag discharge efficiency and operational stability of the centrifuge.
