Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, specifically a horizontal centrifuge with a slagging function. Background Technology

[0002] A centrifuge is a device that uses centrifugal force to separate different substances. It is widely used in many industrial fields such as chemical, pharmaceutical, and food industries. In the chemical industry, it can be used to separate products and by-products after chemical reactions. For example, in the production of synthetic resins, centrifuges can separate resin particles from the reaction solution. In the pharmaceutical field, it is used to separate the active ingredients and impurities in drugs, or to extract drug components such as antibiotics from microbial fermentation broth. In the food industry, centrifuges are indispensable for operations such as separating cream from milk and removing sediment from fruit juice.

[0003] During the centrifugation process, residues are generated. In mineral processing, horizontal centrifuges are used to separate useful minerals and tailings from ore. The tailings will form residues on the inner wall of the centrifuge drum. After the separation is completed, these residues in traditional horizontal centrifuges often adhere tightly to the inner wall of the drum or other key components, which will lead to uneven material distribution and reduce separation efficiency.

[0004] Therefore, this utility model provides a horizontal centrifuge with a slagging function to solve the above problems. Utility Model Content

[0015] (III) Beneficial Effects

[0016] By combining grinding and tamping, residues can be prevented from accumulating in critical parts of the centrifuge. In industrial production, some reaction residues may be sticky.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a horizontal centrifuge with a slagging function, such as Figures 1 to 5 As shown, the centrifuge includes an inner casing 1. The outer arc surface of the inner casing 1 has filter residue holes. Stepped surfaces 101 are provided on both the front and rear sides of the inner casing 1. A filter residue discharge pipe 2 is bolted to the upper surface of one of the stepped surfaces 101. A bearing cavity is provided on the lower surface of the filter residue discharge pipe 2. A sealing gasket 3 is movably fitted onto the outer arc surface of the bearing cavity of the filter residue discharge pipe 2. Both the upper and lower surfaces of the sealing gasket 3 have abutment grooves 301. One abutment groove 301 engages with the outer arc surface of the filter residue discharge pipe 2, while the bottom of the other abutment groove 301... A conical cover 4 is movably engaged with the outer surface of the conical cover 4. A retaining ring 401 is provided at the top of the outer arc surface of the conical cover 4. A retaining end 302 is provided at the middle of the inner arc surface of the sealing gasket 3. The retaining end 302 is movably engaged with the retaining ring 401. An inner groove 402 is provided on the lower surface of the conical cover 4. A transmission rod A5 is movably connected to the top of the inner arc surface of the inner groove 402. A first bevel gear 6 is fixedly installed on the outer arc surface of the transmission rod A5. A transmission rod B7 is movably connected to the middle of the inner sidewall of the inner groove 402.

[0026] The outer grinding sleeve 10 is made of metal and includes an inner grinding blade 16 that is mounted on the connecting rod 13 of the rotating shaft and can be driven to rotate by the rotating shaft; a blade 11 that surrounds the inner grinding blade 16 at intervals and can cooperate with the outer grinding sleeve 10 to grind the object to be ground; and a ring sleeve 12 that is fitted around the outer grinding sleeve 10. The inner grinding blade 16 is generally truncated cone-shaped and has a blade 11 facing the outer grinding sleeve 10. The inner grinding blade 16 has a blade 11 that faces the inner blade surface 15 and together defines a grinding space. Therefore, the residue after filtration can be further ground by rotating the outer grinding sleeve 10, so that the protrusion of the blade 11 rotates relative to the inner blade surface 15 on the undulating inner grinding blade 16.

[0027] In the field of mineral processing, if some ore particles are ground to reduce their particle size before centrifugation, the separation of mineral components of different densities will be easier during the centrifugation process. This is because smaller particles have a larger specific surface area, and under the action of centrifugal force, different components can be separated into layers more quickly according to their density differences, thereby effectively improving the efficiency of centrifugal separation.

[0028] A cam 9 is fixedly installed on one side of the second bevel gear 8. An outer grinding tool sleeve 10 is movably connected to the top of another stepped surface 101. A tool 11 is provided on the inner arc surface of the outer grinding tool sleeve 10. A connecting surface is provided on the side of the outer grinding tool sleeve 10 near the tool 11. A ring sleeve 12 is sleeved in the middle of the upper surface of the outer grinding tool sleeve 10. A cutting edge is provided on the inner arc surface of the ring sleeve 12. A connecting rod 13 is movably engaged on the lower surface of the cam 9. A connecting groove 14 is provided at the top of the connecting rod 13. An inner cutting surface 15 is fixedly installed on the end of the connecting rod 13 away from the cam 9. An inner grinding tool 16 is provided on the outer arc surface of the inner cutting surface 15. The outer arc surface of the inner grinding tool 16 is movably adapted to the outer grinding tool sleeve 10. A spring 17 is movably sleeved at the connection between the connecting rod 13 and the inner grinding tool 16. The second bevel gear 8 is meshed with the first bevel gear 6. The connecting rod 13 is placed in the middle of the centrifugal inner casing 1.

[0029] Meanwhile, a micro motor is connected to the transmission rod A5. Driven by the motor, the outer arc surface of the first bevel gear 6 meshes with the second bevel gear 8. As they rotate relative to each other, one point of the cam 9 on one side rotates around the second bevel gear 8. The rotation of the cam 9 pulls the connecting rod 13. The up and down movement of the cam 9 can move the inner grinding knife 16 inside the outer grinding knife sleeve 10. Therefore, it can not only be pounded up and down, but also be used to grind in conjunction with the outer grinding knife sleeve 10.

[0030] The combination of grinding and tamping can prevent residue from accumulating in critical parts of the centrifuge. In industrial production, some reaction residues may be sticky. If centrifugal force alone is not enough to completely remove them from the equipment, grinding reduces the stickiness and refines the residue, while tamping can remove these residues from the discharge port and other parts in a timely manner, preventing residue from clogging the discharge channel and ensuring that the centrifuge can operate continuously and stably.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
