Description

Technical Field

[0001] The utility model belongs to the technical field of quinolinecarboxylic acid ethyl ester production, in particular to a centrifugal drying system for quinolinecarboxylic acid ethyl ester production. Background Art

[0002] Ethyl quinolinecarboxylate (CAS No. 112811-71-9) is a white crystalline powder. The production of ethyl quinolinecarboxylate uses tri-n-propylamine, ethyl N,N-dimethylaminoacrylate, 2,4,5-trifluoro-3-methoxybenzoyl chloride as raw materials, and the product is obtained after acylation, amination, and cyclization.

[0003] In traditional centrifugation for the production of ethyl quinolinecarboxylate, a uniform feed rate often occurs. However, in actual application, when separating lighter materials at low speeds, a larger feed rate is not suitable because the material to be centrifuged will be directly rebounded by the material being fed at this time if the feed rate is too fast, resulting in low separation efficiency and inconvenience. There is no structure that can automatically adjust the feed rate according to the specific conditions of the separation. Utility Model Content

[0008] Furthermore, the feed opening at the top of the sealing shell is sealed by the feed adjustment assembly, and the feed opening includes a blocking frame covering the feed opening, a U-shaped frame is slidingly provided at the bottom of the blocking frame, a blocking plate is fixedly connected to one side of the U-shaped frame, and the U-shaped frame drives the blocking plate to move to change the connectivity size of the feed opening.

[0009] Furthermore, the blocking plate tightly blocks the blocking frame and the top of the shell, one side of the blocking plate is arranged in a T shape and is fixedly connected to the outer side of the blocking frame by a spring.

[0010] Furthermore, the inflatable box is slidably connected to the U-shaped frame and the inflatable box is inflated through the air pipeline to squeeze the U-shaped frame to move and push the blocking plate to move.

[0011] Furthermore, the power device is specifically a motor, the output shaft of the motor is fixed to one end of the main shaft extending out of the outside of the shell, and the motor is fixedly connected to the top of the shell through an L-shaped plate.

[0012] Furthermore, a collecting bin is provided inside the shell below the level of the centrifugal disc and the diameter of the collecting bin is larger than the diameter of the shell for receiving materials of different weights at different speeds. A discharge pipe is fixedly connected to the bottom of the shell.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The driving wheel can be used to drive the driven wheel to rotate, and when the driven wheel rotates, the blades can be driven to rotate, and the rotation of the blades is used to inflate the inside of the shell. When the speed is not high, the gas will be discharged through the air outlet. At this time, the gas filled into the inflatable box by the gas pipeline cannot drive the blocking plate to move a large distance. In the state of low feeding rate, the blade speed increases, and the gas outlet of the shell can no longer be completely discharged in real time, resulting in a large amount of gas inside the shell being filled into the gas pipeline until it is filled into the inflatable box, driving the U-shaped frame and the blocking plate to move a large distance, so that the blocking plate moves out of the feed port on the shell over a large area. The whole process can adaptively adjust the feeding rate to make the whole centrifugal efficiency greater. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The speed measuring assembly 4 includes a connecting shaft 404 fixedly connected to the driven wheel 10. The connecting shaft 404 is movably connected to a housing 401 via a sealed bearing. The housing 401 is fixed to the housing 12 via a support frame 402. The connecting shaft 404 extends into the housing 401 at one end, which is fixedly connected to a blade 406. An air inlet 405 is formed in the housing 401 on one side of the blade 406. The housing 401 is fixedly connected to the gas pipeline 3 on the side away from the air inlet 405 and has an air outlet 403 smaller than the air inlet 405.

[0024] The feed opening at the top of the sealing shell 12 is sealed by the feed adjustment component 2. The feed adjustment component 2 includes a blocking frame 203 covering the feed opening. A U-shaped frame 201 is slidingly provided at the bottom of the blocking frame 203. A blocking plate 204 is fixedly connected to one side of the U-shaped frame 201 and the blocking plate 204 is driven to move by the U-shaped frame 201 to change the connectivity size of the feed opening.

[0025] Specifically, the blocking plate 204 tightly blocks the blocking frame 203 and the top of the shell 12 . One side of the blocking plate 204 is arranged in a T shape and a spring 202 is fixedly connected to the outer side of the blocking frame 203 .

[0026] Specifically, the inflatable box 8 is slidably connected to the U-shaped frame 201 and the inflatable box 8 is inflated through the gas pipeline 3 to squeeze the U-shaped frame 201 to move and push the blocking plate 204 to move.

[0027] Specifically, the power device is a motor 5 , the output shaft of the motor 5 is fixed to one end of the main shaft 11 extending out of the outside of the housing 12 , and the motor 5 is fixedly connected to the top of the housing 12 via an L-shaped plate.
