Abstract
Description
Technical Field
[0001] This utility model relates to the field of chlorophenylglycine decolorization technology, and in particular to a device for decolorizing p-chlorophenylglycine synthesis. Background Technology
[0002] p-Chlorophenylglycine is an important intermediate in the synthesis of antibiotics, pesticides and liquid crystal materials. Its synthesis process usually involves reactions such as benzene ring chlorination and glycine condensation. In the crude product purification stage, unreacted raw materials, by-products and colored impurities often remain in the reaction solution, which seriously affects the purity of the product and subsequent crystallization processes. Therefore, it is necessary to decolorize it.
[0003] Application No. 202320367026.4 relates to the field of p-chlorophenylglycine decolorization technology, specifically a decolorization device for p-chlorophenylglycine synthesis, comprising: a tank with a sealing cover; a rotating shaft vertically disposed within the tank, on which multiple sets of stirring blades are disposed, the upper end of the rotating shaft penetrating the sealing cover and connected to a drive assembly, the drive assembly including: a motor disposed on a support plate vertically disposed on the sealing cover, with a disc disposed at its output end; a connecting frame slidably disposed on the support plate, the upper end of the connecting frame connected to a first end of a connecting rod shaft, the second end of the connecting rod connected to an eccentrically disposed mounting rod shaft on the disc shaft, and the upper end of the rotating shaft connected to the connecting frame shaft; a power component disposed on the connecting frame; multiple decolorization cylinders disposed vertically at intervals on the rotating shaft and detachably connected to the rotating shaft via a connecting assembly, the decolorization cylinders being filled with activated carbon. This invention has the advantages of good decolorization effect on solutions and easy replacement of activated carbon.
[0004] The above-mentioned solution has shortcomings in use. When cleaning the inner wall of the reaction vessel with a brush, the natural gaps between the brush fibers cause pigments, impurities, and residual reactants to accumulate in the gaps between the brush bristles. When the brush comes into contact with a new batch of material, the residual pigments will be slowly released, which will increase the pigment content of the new batch of material. An additional amount of activated carbon is required to achieve a good decolorization effect, which further increases the production cost. Therefore, we provide a decolorization device for the synthesis of p-chlorophenylglycine. Utility Model Content

[0026] As attached Figure 1 To be continued Figure 3 As shown: A decolorizing device for the synthesis of p-chlorophenylglycine includes a tank 1 and a cover 2 installed on the top of the tank 1. A decolorizing component 3 is provided on the cover 2. The decolorizing component 3 includes a motor 301 installed on the upper surface of the cover 2. A rotating rod 302 is fixedly connected to the output end of the motor 301. A decolorizing cylinder 303 arranged in a ring is detachably installed on the outside of the rotating rod 302. Activated carbon is placed inside the decolorizing cylinder 303. When the motor 301 is working, the rotating rod 302 will drive the decolorizing cylinder 303 to stir inside the solution. The activated carbon loaded in the decolorizing cylinder 303 effectively removes the pigment components in the solution through physical adsorption.
[0027] As attached Figure 1 Appendix Figure 2 With appendix Figure 4 As shown: A cleaning component 4 for cleaning the inner wall of the tank 1 and the exterior of the decolorizing component 3 is provided below the top of the cover 2. The cleaning component 4 includes a rotating plate 401 located below the cover 2 and fitted onto the exterior of the decolorizing component 3. The rotating plate 401 has a through hole larger than the diameter of the rotating rod 302, so that the rotation of the rotating plate 401 and the rotating rod 302 do not interfere with each other. Spray nozzles 402 are rotatably connected to both ends of the rotating plate 401. The input end of each spray nozzle 402 is connected to a telescopic tube 403, and the input end of the telescopic tube 403 extends to the top of the cover 2. Cleaning water is injected into the telescopic tube 403 by an external high-pressure pump, and high-pressure water is forcefully sprayed out from the spray nozzles 402. The cleaning component 4 also includes a push-pull structure located above the rotating plate 401 for adjusting the cleaning direction of the spray nozzles 402. The push-pull structure includes a set of electric push rods 404 mounted on the upper surface of the rotating plate 401. Each electric push rod 404 has a movable plate 405 mounted on its telescopic end. Each movable plate 405 has a push-pull plate 406 hinged to its other end. Each push-pull plate 406 has its other end hinged to the outer surface of the nozzle 402. The electric push rods 404 are controlled to start reciprocating motion. The nozzle 402 is periodically deflected by the linkage mechanism of the movable plate 405 and the push-pull plate 406, so as to achieve directional rinsing of the inner wall of the tank 1 and the outer surface of the decolorizing component 3. Each movable plate 405 has a U-shaped frame 407 slidably connected to its outer surface. The bottom end of each U-shaped frame 407 is connected to the upper surface of the rotating plate 401. The U-shaped frame 407 can limit and guide the movable plate 405 to ensure its smooth movement.
[0028] As attached Figure 1 Appendix Figure 2 With appendix Figure 4 As shown: The drive structure that drives the nozzle 402 to rotate around the tank 1 includes a motor 408 mounted on the bottom surface of the cover 2. A gear 409 is mounted on the output end of the motor 408. A gear ring 410 meshes with the outside of the gear 409. A sleeve 411 is fixedly connected to the inner wall of the gear ring 410. The bottom end of the sleeve 411 is connected to the upper surface of the rotating plate 401. When the motor 408 is working, it drives the gear 409 to mesh with the gear ring 410, causing the sleeve 411 and the rotating plate 401 to reciprocate along the axis of the rotating rod 302, thereby forming a three-dimensional cleaning effect. This multi-degree-of-freedom cleaning system can thoroughly remove residual pigments, preventing pigments from the previous batch of solution from being released into the new batch of solution, avoiding extra consumption of activated carbon due to contamination, and effectively reducing production costs. A limiting rod 412 is fixedly connected to the outer surface of the sleeve 411, and a limiting frame 413 is slidably connected to the top of the limiting rod 412. The upper surface of the limiting frame 413 is connected to the inner top wall of the cover 2. By using the cooperation of the limiting rod 412 and the limiting frame 413, the rotation of the sleeve 411 can be limited to prevent the telescopic tube 403 from deflecting too much and becoming entangled.
[0029] As attached Figure 1 With appendix Figure 5 As shown: A sealing assembly 5 is provided on the exterior of the tank body 1 and the exterior of the cover 2. The sealing assembly 5 includes an annular frame 501 fixedly connected to the outer surface of the tank body 1. An annular cylinder 502 is inserted into the interior of the annular frame 501. The inner wall of the annular cylinder 502 is connected to the outer surface of the cover 2. When the cover 2 is placed on top of the tank body 1, the annular cylinder 502 will be inserted into the annular frame 501, thereby forming a seal at the connection between the annular cylinder 502 and the annular frame 501. The outer surface of the annular cylinder 502 is equipped with annularly arranged bolts 503. The outer surface of the annular frame 501 is equipped with annularly arranged connecting plates 504. Each bolt 503 is connected to each connecting plate 504. When installing the annular cylinder 502, the bolts 503 are precisely passed through the connecting plates 504 and then connected with nuts, which can firmly fix the cover 2 to the top of the tank body 1 and prevent loosening caused by vibration or pressure fluctuations during operation.
[0030] Working principle: During the decolorization process, the control system first starts the motor 301 to drive the rotating rod 302 to rotate, which in turn drives the decolorization cylinder 303 to fully stir the solution in the tank 1. The activated carbon loaded in the decolorization cylinder 303 effectively removes the pigment components in the solution through physical adsorption. When a new batch of material needs to be processed, the cleaning water is first injected into the telescopic pipe 403 by an external high-pressure pump. The high-pressure water jet is powerfully sprayed out from the nozzle 402. At the same time, the electric push rod 404 starts to reciprocate. Through the linkage mechanism of the moving plate 405 and the push-pull plate 406, the... The nozzle 402 generates periodic deflection to achieve directional rinsing of the inner wall of the tank 1 and the outer surface of the decolorizing component 3. Then, the motor 408 can be controlled to work. The motor 408 drives the gear 409 to mesh with the gear ring 410, so that the sleeve 411 and the rotating plate 401 reciprocate along the axis of the rotating rod 302, thereby forming a three-dimensional cleaning path. This multi-degree-of-freedom cleaning system can thoroughly remove residual pigments, avoid the release of pigments from the previous batch of solution into the new batch of solution, avoid the extra consumption of activated carbon due to contamination, and effectively reduce production costs.
