[0004] In the above patent, when the materials in the centrifugal cylinder are discharged after centrifugation, the centrifugal cylinder is pulled upward, so that the materials can overflow from the lower part to the outside, thereby achieving the discharging effect. However, during the centrifugation process, the liquid is thrown out of the centrifugal cylinder, and the solid materials are adhered to the inner wall of the centrifugal cylinder and even partially blocked in the holes of the side wall of the centrifugal cylinder due to the centrifugal effect. By pulling the centrifugal cylinder upward for disassembly, some materials may not fall downward and need to be manually cleaned by the workers, which is inconvenient for operation. Meanwhile, during the industrial production of salicylanilide, the processing amount is large, and in order to improve the production efficiency, as much as possible is added in one centrifugation process. If too much material is added, the materials adhered to the inner wall of the centrifugal cylinder may be left after centrifugation, which may cause insufficient centrifugation and poor centrifugation effect. SUMMARY

[0041] As shown in Figures 1-8As shown, the filter bag 13 is annularly arranged, and the filter bag 13 is connected with the centrifugal cylinder 2 or the inner cylinder 5 in the same way, the upper and lower ends of the filter bag 13 are respectively connected with the upper and lower ends of the inner side of the centrifugal cylinder 2 or the inner cylinder 5, the inner side of the upper end of the centrifugal cylinder 2 is provided with a first assembly groove 201, one end of the second cylinder 12 is arranged in the first assembly groove 201, the other end of the second cylinder 12 is connected with the inner side of the upper end of the filter bag 13, and the second cylinder 12 is provided with a plurality of second cylinders 12, when discharging, the upper end of the filter bag 13 is quickly inwards contracted by quickly elongating the second cylinder 12, the filter bag 13 is deformed as a whole, so that the solid materials attached to the filter bag 13 can be separated from the filter bag 13 and fall downwards, thereby realizing quick and effective discharging operation.

[0043] As shown in Figures 1-8 the inner lower end of the centrifugal cylinder 2 is provided with a second assembly groove 204, the second assembly groove 204 is provided with a vibration machine 205, and the output end of the vibration machine 205 is connected with the inner side of the filter bag 13, the vibration machine 205 can effectively increase the vibration feeling of the filter bag 13 and improve the success rate of discharging the materials on the filter bag 13, and the vibration machine 205 is a waterproof vibration motor.

[0044] Working principle: when centrifugation is performed, the first cylinder 8 is driven to elongate, so that the bottom support 9 rises until the bottom support 9 is sealingly connected with the lower end of the centrifugal cylinder 2 and the lower end of the inner cylinder 5, and then the material to be centrifuged is introduced into the inner cylinder 5 and the space between the inner cylinder 5 and the centrifugal cylinder 2. Due to the setting of the bottom support 9, the material cannot leak from the lower end, and then the upper end cover 10 is covered, and the two limiting plates 11 are respectively in the inner cylinder 5 and the centrifugal cylinder 2. By driving the motor 7, the bottom support 9 is driven to rotate at high speed, so that the centrifugal cylinder 2 and the inner cylinder 5 rotate at high speed, thereby realizing the effect of centrifugation. During centrifugation, solid materials cannot pass through the filter bag 13 and the centrifugal cylinder 2 or the inner cylinder 5, so as to remain in the centrifugal cylinder 2 or the inner cylinder 5 and adhere to the inner wall. Liquid material passes through the filter bag 13 and the centrifugal cylinder 2 or the inner cylinder 5 during rotation and enters the space between the centrifugal housing 1 and the centrifugal cylinder 2 or the space between the inner cylinder 5 and the water retaining ring 6. Since the end cover 10 is fixed relative to the centrifugal housing 1, when the centrifugal cylinder 2 rotates, the limiting plate 11 inside is in a rotating state relative to the inner cylinder 5. The inner cylinder 5 and the centrifugal cylinder 2 are relatively long, and when more material is placed in the centrifugal cylinder 2 and the inner cylinder 5, part of the material may accumulate at the bottom and be difficult to be rolled to the upper end during centrifugation. Through the setting of the limiting plate 11, the bottom material can be quickly rolled up, so that all the materials are uniformly adhered to the inner wall of the inner cylinder 5 or the centrifugal cylinder 2, so that the materials at different positions have the same centrifugation effect. At the same time, by setting the centrifugal cylinder 2 inside the centrifugal cylinder 2, when the same amount of material is added in the centrifugal cylinder 2, the thickness of the material adhered to the inner wall of the centrifugal cylinder 2 is thicker than that when the inner cylinder 5 is provided, and the required centrifugation time is longer, which may also cause poor centrifugation effect. By setting the inner cylinder 5, part of the pressure of the material is shared, so that the thickness of the material adhered to the inner wall of the inner cylinder 5 and the centrifugal cylinder 2 is not too thick, so that the centrifugation effect is better. After centrifugation is completed, the driving motor 7 can be stopped, and then the first cylinder 8 is retracted to move the bottom support 9 downward, so that the lower end of the centrifugal cylinder 2 and the lower end of the inner cylinder 5 are communicated with the outside. At this time, the second cylinder 12 is elongated to unfold the filter bag 13 originally adhered to the inner wall of the inner cylinder 5 or the centrifugal cylinder 2, so that the filter bag 13 is separated from the inner wall of the inner cylinder 5 or the centrifugal cylinder 2, thereby realizing the quick shaking off of the solid material on the filter bag 13, so as to realize the quick discharge of the material, and there is no residue on the inner cylinder 5 and the centrifugal cylinder 2, thereby saving the labor of manual cleaning by workers. After the discharge is completed, the second cylinder 12 is retracted to reset the filter bag 13, which is simple to operate and convenient to use.

[0045] The above merely describes preferred embodiments of the present application, but is not intended to limit the present application to other forms, any person skilled in the art can make changes or modifications to the above disclosed technical contents into equivalent embodiments with equivalent changes, and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical solution content of the present application still belongs to the protection scope of the present application technical solution.
