AI Technical Summary

Technical Problem

In the final stage of processing, existing centrifugal separation devices for dye intermediates have difficulty in timely removing water vapor and dye intermediate gas components from the inner wall of the centrifugal separation tank. This causes water mist to condense into powder and adhere to the inner wall, affecting the output.

Method used

The centrifugal separation tank adopts a single open structure and is equipped with a gas pressure diversion pipe and a secondary filter screen inside the sealed cover. The water vapor is formed into water droplets by air pressure jet and flows to the secondary filter screen to realize the re-condensation and recovery of dye intermediates.

Description

TECHNICAL FIELD

[0001] The utility model relates to the field of dye purification, specifically refers to a centrifugal separation device for dye intermediate. BACKGROUND

[0002] Dye intermediate refers to various aromatic hydrocarbon derivatives for producing dyes and organic pigments, which are intermediate products for manufacturing dyes, pesticides, medicines, resins, auxiliaries, plasticizers and other products. Dye intermediate is initially used for manufacturing dyes, so it is also called dye intermediate. The synthesis process of dye intermediate includes raw material selection, intermediate generation, intermediate conversion and intermediate purification. The purification of intermediate mainly relies on a centrifugal separation device for dye intermediate.

[0003] The existing centrifugal separation device for dye intermediate mainly drives the centrifugal purification tank to rotate at high speed in the centrifugal separation tank body through a rotating motor. Under the action of the same centrifugal force, impurities, waste liquid and intermediate penetrate the side separation hole of the centrifugal purification tank at different speeds. The impurities inside the dye intermediate are thrown out of the centrifugal purification tank, so as to purify the dye intermediate.

[0004] This device can quickly purify the dye intermediate in a short time through centrifugal force. However, during the swinging of the centrifugal purification tank, some dye intermediate will be carried out of the centrifugal purification tank by water vapor and then thrown onto the inner wall of the centrifugal separation tank body. After the water vapor condenses into water droplets, it slides downward and flows into the water outlet of the centrifugal separation tank body. However, after the centrifugal purification tank stops rotating, water mist will remain on the inner wall of the centrifugal separation tank body. Because the volume of the water mist is too small, the dye intermediate components in the water mist adhere to the inner wall of the centrifugal separation tank body. After a long time of normal temperature evaporation, the dye intermediate will condense into a powder layer and stick to the inner wall of the centrifugal separation tank body. UTILITY MODEL CONTENTS

[0005] The technical problem to be solved by the utility model is that the water vapor and dye intermediate gas components on the inner wall of the centrifugal separation tank body cannot be discharged in time during the finishing stage of the existing centrifugal separation device for dye intermediate.

[0007] As improved, the bottom end of the centrifugal purification tank is provided with a detachable fixing plate, one side of the detachable fixing plate is provided with a polygonal fixing column, and the polygonal fixing column penetrates the bottom end of the centrifugal purification tank.

[0008] As improved, the output shaft of the rotary motor penetrates the bottom end of the centrifugal separation tank body and the bottom end of the detachable fixing plate, the output shaft of the rotary motor is connected with the through hole at the bottom end of the detachable fixing plate through a connecting key, the rotary motor is connected with the bottom of the centrifugal separation tank body through a bolt structure, and the detachable fixing plate and the bottom of the centrifugal purification tank and the centrifugal separation tank body and the sealing cover are all connected through buckling.

[0010] As improved, the side of the centrifugal separation tank body is provided with a cleaning door above the secondary filter screen, and the inside of the centrifugal separation tank body is provided with a bevel water control port below the secondary filter screen.

[0011] As improved, the secondary filter screen is connected with the inner wall of the centrifugal separation tank body through a bolt structure.

[0012] Compared with the prior art, the device has the advantages that: in the process of machining, the inner wall of the centrifugal separation tank body is sprayed with air in real time through the air pressure shunt pipeline in the sealing cover, so that the water vapor on the inner wall of the centrifugal separation tank body forms water droplets quickly, and then flows to the secondary filter screen on the bottom surface of the centrifugal separation tank body, and the dye intermediate is re-aggregated through the secondary filter screen, so that the yield of the dye intermediate is improved, and the phenomenon that the dye intermediate is adhered to the inner wall of the centrifugal separation tank body is avoided.
