[0002] The production process of sodium thiosulfate involves centrifugation, which is usually carried out after the crystallization step. The centrifugal device effectively separates the solid-liquid mixture, that is, separates the crystallized sodium thiosulfate solid and the mother liquor.

[0003] The patent with the patent authorization announcement number CN219273341U discloses a centrifugal device for sodium thiosulfate production, the centrifugal device includes a box, the top of the box is hinged with a cover plate, the top of the cover plate is provided with an upper fixing mechanism, the top surface of the box is provided with a centrifugal chamber, the interior of the box is provided with a servo motor, the output shaft of the servo motor extends to the inner cavity of the centrifugal chamber and is fixedly connected with a rotating disk, and an outer filter box is placed on the top of the rotating disk. The centrifugal device is used in conjunction with an outer filter box, a placement rack, and an inner filter box. When the sodium thiosulfate crystals with a larger diameter in the sodium thiosulfate mixed liquid in the inner cavity of the inner filter box enter the inner cavity of the outer filter box, there is a certain height difference between the bottom of the inner cavity of the outer filter box and the bottom of the inner cavity of the inner filter box, thereby avoiding the remixing of the separated sodium thiosulfate crystals, and improving the working quality of the centrifugal device for sodium thiosulfate production. However, during centrifugation, the material thrown out by the centrifugation will remain on the barrel wall, and the centrifugal device cannot scrape the material remaining on the barrel wall, which causes a waste of raw materials and is not conducive to subsequent cleaning.

[0004] For this reason, we propose a centrifugal device for sodium thiosulfate production which can automatically scrape off the residual materials on the barrel wall during centrifugation. Utility Model Content

[0005] In order to overcome the shortcomings of the existing centrifugal device that it is unable to scrape the residual materials on the barrel wall, causing a waste of raw materials and being unfavorable for subsequent cleaning, the utility model provides a centrifugal device for sodium thiosulfate production which can automatically scrape the residual materials on the barrel wall during centrifugation.

[0006] A centrifugal device for sodium thiosulfate production comprises a bracket, a treatment box is fixedly connected to the top of the bracket, a liquid discharge pipe is connected to the side of the treatment box close to the bracket, a detachable machine cover is connected to the top of the treatment box, a feed hopper is connected to the machine cover, a motor is fixedly connected to the side of the bracket close to the treatment box, a connecting shaft is rotatably connected to the center position of the treatment box, the bottom end of the connecting shaft is connected to the motor output shaft, a centrifugal cylinder is fixedly connected to the side of the connecting shaft away from the motor, and a full gear ring is also included, the full gear ring is fixedly connected to the top of the treatment box, the machine cover is fixedly connected to a connecting rod, a gear is rotatably connected to the connecting rod, the gear is meshed with the full gear ring, a missing gear ring is fixedly connected to the side of the full gear ring close to the gear, the missing gear ring is rotatably meshed with the gear, the full gear ring is fixedly connected to a scraper, and the scraper is fitted to the inner wall of the treatment box.

[0007] In addition, it is particularly preferred that a water tank is further included, which is fixedly connected to the top of the bracket, a support plate is fixedly connected to the top of the water tank, a water pump is fixedly connected to the support plate, and water pipes are connected to both sides of the water pump, the tail end of the water pipe on one side is connected to the water tank, and the tail end of the water pipe on the other side is connected to the machine cover.

[0009] Furthermore, it is particularly preferred that a baffle is slidably connected to the discharge pipe.

[0010] Furthermore, it is particularly preferred that a cover is screwed onto the water tank.

[0011] Furthermore, it is particularly preferred that the water pipe is a hose to facilitate opening and closing of the machine cover.

[0012] This application has the following advantages:

[0013] 1. The raw materials are introduced into the centrifuge, and the centrifuge rotates at high speed to throw out the mother liquor. The thrown mother liquor is located in the treatment box, while the sodium thiosulfate solid remains in the centrifuge. When the centrifuge rotates at high speed, the missing tooth ring and the gear cooperate to reduce the speed and drive the full tooth ring to rotate at a uniform speed. The rotation of the full tooth ring drives the scraper to rotate. The rotation of the scraper can scrape down the residual material on the inner wall of the treatment box, avoiding the waste of raw materials and facilitating the subsequent cleaning.
