[0002] A centrifuge is a machine that uses centrifugal force to separate liquids from solid particles or components in a mixture of liquids and liquids. In industrial applications, in order to separate solids and liquids as needed, filter materials of different mesh sizes, i.e. filter cloths or filter bags, are required. The filter materials can provide different separation requirements for the separation process. At the same time, the filter materials have a service life and need to be replaced after a certain period of use. Therefore, the filter materials need to be replaced to meet different needs or when they expire.

[0003] Most existing filter materials use filter cloth or filter bags, which are flexible materials. When replacing the filter material, it is necessary to take out the filter material and align and cover the middle and four sides of the filter material with the inside of the centrifuge to prevent leakage. The flexible characteristics of the filter material undoubtedly increase the difficulty of installation. Summary of the Invention

DETAILED DESCRIPTION

[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example: Refer to Figures 1 to 8 A filter material replacement structure includes a filter cartridge 1 and a filter material connecting assembly 2. The filter material connecting assembly 2 is placed in the filter cartridge 1 for connecting the filter material. The filter material connecting assembly 2 includes an L-shaped bracket 201 corresponding to the circumferential side and bottom plate of the filter cartridge 1 and an inclined bracket 202 corresponding to the conical filter cartridge in the middle of the filter cartridge 1. The top of the inclined bracket 202 is fixedly connected with a connecting ring 203. Clamping assemblies are provided at the corners, top and middle of the L-shaped bracket 201 and the connecting ring 203. The clamping assembly is used to clamp the filter material.

[0033] The clamping assembly includes fixed clamps 205 fixedly installed at the corners and top of the L-shaped bracket 201. A slot is provided on the L-shaped bracket 201 corresponding to the position of the fixed clamp 205, and a movable clamp 206 is rotatably connected to the slot via a torsion spring.

[0034] When installing the filter bag or filter cloth, first clamp the center of the conical filter cloth or filter bag in the clamping assembly of the connecting ring 203, then cover the filter material downward so that it covers the L-shaped bracket 201, and then place the sealed edge of the filter cloth or filter bag on the clamping assembly of the L-shaped bracket 201. Use the clamping assembly to fix the sealed edge position of the filter material, that is, the horizontal part of the filter material and the vertical circumferential side part. In this way, the filter material can be fixed relatively accurately. At the same time, fixing the center point first can facilitate the replacement of the filter material, and can also place the filter material more fit and accurately in the filter material connecting assembly 2.

[0035] When clamping the bottom and top edge seals of the filter material, the edge seals of the filter material can be pressed between the fixed clamping plate 205 and the movable clamping plate 206, and the torsion spring on the movable clamping plate 206 can be used to clamp the edge seals of the filter material to help fix and position the top and bottom edge seals of the filter material.

[0036] The movable splint 206 includes a splint portion 2061 that provides a clamping function. The tail end of the splint portion 2061 extends obliquely to one side to form a movable contact portion 2062. The end of the movable contact portion 2062 contacts the filter cartridge 1. The movable splint 206 is close to the circumferential side of the filter cartridge 1, and the movable contact portion 2062 produces relative sliding on the circumferential side of the filter cartridge 1.

[0037] During the centrifugal separation process, the filter material connecting assembly 2 will rotate at high speed under the drive of the motor to achieve solid-liquid separation or liquid-liquid separation. During this process, the filter material and the L-shaped bracket 201 will be subjected to great pressure during the centrifugal movement, and the movable splint 206 on the L-shaped bracket 201 will be forced to move closer to the circumferential side of the filter cartridge 1. During this process, the movable contact portion 2062 will produce relative sliding within the circumferential side of the filter cartridge 1 due to its inclined characteristics, causing the movable splint 206 to rotate in the L-shaped bracket 201, and causing the splint portion 2061 to turn towards the fixed splint 205, which can allow the fixed splint 205 and the movable splint 206 to clamp the filter material more tightly, so that the filter material can be better fixed near the L-shaped bracket 201 during the centrifugal process, reducing the sliding distance of the filter material during the centrifugal process, and achieving a better fixing effect.

[0038] The clamping assembly also includes a fixed frame 204 fixedly installed in the middle of the connecting ring 203 through a connecting rod. Two clamping plates 207 are symmetrically connected to the fixed frame 204 through torsion springs. The bottoms of the two clamping plates 207 are inclined outward and extended to form a sliding portion 210.

[0039] When installing the filter material, the center of the conical part in the middle of the filter material can be clamped between the clamping plates 207 to complete the positioning of the filter material. Then the rest of the filter material can be completely laid on the L-shaped bracket 201 and the inclined bracket 202, which is convenient for fixing the edge of the filter material on the L-shaped bracket 201. A through groove 208 is provided on the top of the L-shaped bracket 201, and a plurality of L-shaped limit rods 209 are fixedly connected to the top of the filter cartridge 1. The L-shaped limit rods 209 limit the position of the L-shaped bracket 201 after rotation.

[0040] When the filter material needs to be replaced, the L-shaped bracket 201 can be lifted up. After the filter material is placed on the filter material, the through slot 208 of the L-shaped bracket 201 is aligned with the L-shaped limiting rod 209. After the L-shaped limiting rod 209 passes through the through slot 208, the L-shaped bracket 201 is rotated so that the cross bar portion of the L-shaped limiting rod 209 covers the top of the L-shaped bracket 201, so that the L-shaped limiting rod 209 can limit the position of the L-shaped bracket 201, thereby avoiding position deviation of the L-shaped bracket 201 during centrifugation.

[0041] A pressing assembly 3 is placed at the connection between the L-shaped bracket 201 and the inclined bracket 202. The pressing assembly 3 is used to smooth out the filter material near the conical filter cartridge in the filter cartridge 1. The pressing assembly 3 includes a pressing ring 301. The inner diameter of the pressing ring 301 is connected to multiple smoothing plates 302 by a torsion spring.

[0042] After the center of the filter material is placed in the clamping assembly, the pressing ring 301 is slid downward from the conical filter cartridge part of the filter cartridge 1. During the sliding process, the multiple smoothing plates 302 at the inner diameter of the pressing ring 301 can be firmly attached to the filter material under the elastic support of the torsion spring. Under the gravity support of the pressing ring 301, the pressing ring 301 can eventually slide over the cross bar of the L-shaped bracket 201, and press the bottom inner diameter sealing edge of the filter material to the connection between the L-shaped bracket 201 and the inclined bracket 202. In this way, the inner diameter sealing edge of the bottom of the filter material is fixed at the connection between the L-shaped bracket 201 and the inclined bracket 202, and during the sliding process of the pressing ring 301, the smoothing process of the conical part of the filter material is completed.

[0043] The bottom of the pressing ring 301 is fixedly connected to multiple fixed plates 303, and the inside of the pressing ring 301 is slidably connected to multiple movable plates 304 corresponding to the fixed plates 303 through sliding grooves. A movable ring 305 is placed on the top of the pressing ring 301, and the bottom of the movable ring 305 is fixedly connected to a connecting plate 306, and the bottom of the connecting plate 306 is fixedly connected to a baffle 308, and the side wall of the connecting plate 306 is fixedly connected to a protrusion 307 corresponding to the movable plate 304, and the top of the movable ring 305 is fixedly connected to a handle.

[0044] When the filter material is replaced, the handle on the movable ring 305 is lifted to slide the connecting plate 306 below the movable ring 305 upwards, so that the protrusion 307 on the connecting plate 306 contacts the movable plate 304, and the movable plate 304 moves toward the fixed plate 303. The fixed plate 303 and the movable plate 304 are clamped on both sides of the L-shaped bracket 201 by using the fixed fixed plate 303. At the same time, the baffle 308 contacts the bottom of the press ring 301, and the movable ring 305 moves upward to move the press ring 301 and the clamped L-shaped bracket 201 upwards, so that the L-shaped bracket 201 and the filter material can be lifted up together, which is convenient for replacing the filter material outside.

[0045] A centrifuge adopts the above-mentioned filter material replacement structure, including a pressing assembly 3, a filter cartridge 1 rotatably connected in the pressing assembly 3, and a motor drives the filter cartridge 1 to rotate to complete centrifugal separation.
