Description

Technical Field

[0001] This utility model specifically relates to the field of centrifuge technology, and more specifically to a centrifuge with anti-clogging function. Background Technology

[0002] A plate centrifuge is a device that uses centrifugal force to separate materials. When a motor drives the drum to rotate at high speed, the materials inside the drum are subjected to a strong centrifugal force. Due to the density differences between different components in the material, the denser components move rapidly towards the drum wall under the influence of centrifugal force and deposit on the wall, while the less dense components tend to concentrate near the center of the drum, thus achieving the separation of different phases (such as liquid and solid phases, liquid phases of different densities, etc.). For example, in the chemical industry, for some suspensions containing solid particles, the solid particles are thrown onto the drum wall to form a filter cake by the action of a plate centrifuge, while the clear liquid remains in the center of the drum and can be discharged through the corresponding drain port, achieving solid-liquid separation.

[0003] Chinese Patent Publication No. CN 211359223 U discloses a portable flat plate centrifuge, including a frame, a base mounted on the frame, a main shaft mounted on the base via bearing seats, a drum sleeved on the main shaft, and a housing mounted on the base. The drum is located inside the housing. The centrifuge also includes a plurality of shock absorbers mounted on the frame and located below the base, and rollers mounted on the bottom of the frame.

[0004] The centrifuge described in the aforementioned patent is not easy to clean the solid matter on the inner wall of the drum after centrifugation, which can easily lead to clogging of the sieve holes. During centrifugation, the centrifugal separation function may not be completed due to clogging. Furthermore, manual cleaning is required, which is time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this invention is to provide a centrifuge with anti-clogging function. It uses a detachable filter cloth to centrifuge the materials to be centrifuged, and is also equipped with a scraper. After centrifugation, the extension of the cylinder drives the scraper to move up and down, thereby scraping off the solid matter on the filter cloth, thus avoiding the accumulation and clogging caused by the solid matter. Moreover, the detachable filter cloth is very convenient to replace, thus ensuring the centrifugation effect of the materials. This invention aims to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figure 1-6 In this embodiment of the present invention, a centrifuge with anti-clogging function includes a centrifuge shell 2 fixed on a frame body 1, a drain pipe at the bottom of the centrifuge shell 2, and a centrifuge cylinder 3 inside the centrifuge shell 2; the centrifuge cylinder 3 is fixed on a rotating disk 8; and a filter cloth 4 is provided on the inner side of the centrifuge cylinder 3 and above the rotating disk 8.

[0028] The top of the centrifuge housing 2 is fitted with a tank top cover 13; a scraper cylinder 16 is fixed on the tank top cover 13, the cylinder rod of the scraper cylinder 16 extends into the centrifuge cylinder 3 and a scraper 17 is fixed thereon; the scraper 17 is attached to the filter cloth 4 on the inner side of the centrifuge cylinder 3.

[0029] More specifically, a drive shaft 6 is installed at the bottom of the rotating disk 8, and the drive shaft 6 is installed in conjunction with the centrifuge housing 2 through a bearing seat; a driven wheel 9 is installed at the lower end of the drive shaft 6; the driven wheel 9 is connected to the drive wheel 11 installed on the centrifugal motor 12 through a drive belt 10; the centrifugal motor 12 is fixed on the frame body 1.

[0030] By adopting the above technical solution, when the material is centrifuged, the centrifugal motor 12 drives the drive wheel 11 to rotate, and with the cooperation of the transmission belt 10 and the driven wheel 9, the centrifugal cylinder 3 rotates at high speed. Under the strong centrifugal force, the liquid in the material inside the centrifugal cylinder 3 is thrown to the inside of the filter cloth 4, thereby realizing the solid-liquid separation of the material. The thrown liquid is collected in the centrifuge shell 2 and discharged through the drain pipe at the bottom.

[0031] After centrifugation, the centrifuge cylinder 3 continues to rotate, and the cylinder rod of the scraper cylinder 16 gradually extends, causing the scraper 17 to gradually approach the filter cloth 4, thereby scraping off the solid material remaining on the filter cloth 4 and avoiding clogging of the filter cloth 4.

[0032] In this embodiment, the rotating disk 8 has a conical upward protrusion in the middle, and the filter cloth 4 is fixed to the rotating disk 8 in the middle by a locking cap 7. The filter cloth 4 is cylindrical, wrapping around the top edge of the centrifuge cylinder 3, and is secured to the centrifuge cylinder 3 by a retaining ring 5.

[0033] By adopting the above technical solution, after removing the retaining ring 5, the locking cap 7 can be rotated open to remove the filter cloth 4, which facilitates the cleaning of the scraped solid materials. Then, the filter cloth can be cleaned by backwashing with high-pressure water. Compared with the traditional rotary drum, it is easier to clean and disassemble. Filter cloths with different filter holes can be selected according to actual needs, making it more flexible to use.

[0034] Furthermore, the rotating disk 8 is designed with a cone-shaped upward protrusion in the middle, which ensures that the material flows towards the edge of the rotating disk 8, thereby increasing the centrifugal force of the material during centrifugation and improving the centrifugation effect.

[0035] In this embodiment, the top of the tank cover 13 is also provided with a rotary motor 18, which is inclined and a conical throwing bucket 19 is installed on the output shaft of the rotary motor 18; the upper end of the conical throwing bucket 19 is open and through holes are provided around its lower end.

[0036] The tank top cover 13 is provided with a feed pipe 21, the lower end of which is connected to a conveying pipe 20; the other end of the conveying pipe 20 extends into the conical swivel bucket 19.

[0037] By adopting the above technical solution, when adding materials, the materials are first added to the feed pipe 21, and then the materials are conveyed to the conical swivel barrel 19 through the conveying pipe 20. The rotary motor 18 drives the conical swivel barrel 19 to rotate at high speed. Under the action of centrifugal force, the materials will be thrown towards the filter cloth 4. After passing through the filter cloth 4 and the centrifuge cylinder 3, the liquid is thrown into the centrifuge shell 2, thus achieving solid-liquid separation.

[0038] If the separation is incomplete, the solids are ejected a second time by the high-speed rotation of centrifuge tube 3, achieving another round of solid-liquid separation. This centrifugation method greatly improves the centrifugation effect of the centrifuge.

[0039] In this embodiment, a connecting arm 14 is also fixed on the top cover 13 of the tank. The connecting arm 14 is movably connected to the side wall of the centrifuge housing 2 in a hinged structure. The outer end of the connecting arm 14 is movably connected to the fisheye joint on the cylinder rod of the cylinder 15 through a rotating shaft. The lower end of the cylinder 15 is movably connected to the frame body 1 through a hinge seat.

[0040] By adopting the above technical solution, when the cylinder rod of cylinder 15 retracts, the connecting arm 14 and the centrifuge housing 2 can be automatically opened through the hinge structure at the side wall. The structure is simple and easy to operate.

[0041] The working principle of this utility model is as follows: When adding materials, the materials are first added to the feed pipe 21, and then the materials are conveyed to the conical swivel barrel 19 through the conveying pipe 20. The rotating motor 18 drives the conical swivel barrel 19 to rotate at high speed. Under the action of centrifugal force, the materials will be thrown towards the filter cloth 4. After passing through the filter cloth 4 and the centrifuge cylinder 3, the liquid is thrown into the centrifuge shell 2, thus realizing solid-liquid separation.

[0042] If the separation is incomplete, the centrifugal motor 12 drives the drive wheel 11 to rotate, and with the cooperation of the transmission belt 10 and the driven wheel 9, the centrifugal cylinder 3 rotates at high speed. Under the strong centrifugal force, the liquid in the material inside the centrifugal cylinder 3 is thrown to the inside of the filter cloth 4, thereby realizing the solid-liquid separation of the material. The thrown liquid is collected in the centrifuge shell 2 and discharged through the drain pipe at the bottom.

[0043] After centrifugation, the centrifuge cylinder 3 continues to rotate, and the cylinder rod of the scraper cylinder 16 gradually extends, causing the scraper 17 to gradually approach the filter cloth 4, thereby scraping off the solid material remaining on the filter cloth 4 and avoiding clogging of the filter cloth 4.

[0044] After removing the retaining ring 5, rotate the locking cap 7 to open it, and the filter cloth 4 can be removed, making it easier to clean up the scraped solid material. Then, the filter cloth can be cleaned by backwashing with high-pressure water. Compared with the traditional rotary drum, it is easier to clean and disassemble. In addition, different filter cloths with different filter holes can be selected according to actual needs, making it more flexible in use.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
