Description
Technical Field
[0001] The utility model relates to the technical field of p-chlorophenylglycine purification, in particular to a p-chlorophenylglycine purification device. Background Art
[0002] P-chlorophenylglycine is an important organic synthesis intermediate and pharmaceutical intermediate, mainly used for synthesizing drugs. During the preparation process of p-chlorophenylglycine, by-products and other impurities will inevitably be generated. In order to remove the by-products and other impurities generated during the preparation of p-chlorophenylglycine, the obtained p-chlorophenylglycine needs to be purified. At this time, a p-chlorophenylglycine purification device is required. The purification of p-chlorophenylglycine generally includes steps such as dissolution, decolorization, filtration, crystallization, re-filtration, and drying.
[0003] When the existing p-chlorophenylglycine purification device decolorizes and filters the p-chlorophenylglycine solution, most of them use activated carbon particles to decolorize the p-chlorophenylglycine solution. Most of them put an appropriate amount of activated carbon particles into the shell containing the p-chlorophenylglycine solution for decolorization. Then, the p-chlorophenylglycine solution with activated carbon particles and completed decolorization is poured into a container, and finally, the solution is poured into a filtration shell through the container for filtration. In this way, during the solution transfer process, part of the solution is easily adhered to the container wall, resulting in the loss of p-chlorophenylglycine. At the same time, the additional solution transfer step makes the operation process more complex, increasing the labor and time costs, reducing both the use effect and the use efficiency of the p-chlorophenylglycine purification device. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the problem in the existing technology that when the existing p-chlorophenylglycine purification device decolorizes and filters the p-chlorophenylglycine solution, the p-chlorophenylglycine solution needs to be transferred additionally. During the additional solution transfer process, part of the solution is easily adhered to the container wall, resulting in the loss of p-chlorophenylglycine. At the same time, the additional solution transfer step makes the operation process more complex, increasing the labor and time costs, reducing both the use effect and the use efficiency of the p-chlorophenylglycine purification device.

However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.
[0025] As Figures 1 - 5 shown, a purification device for p-chlorophenylglycine includes: a purification mechanism 1, and a stirring mechanism 2 is arranged on the purification mechanism 1;
[0026] The purification mechanism 1 includes a housing 101 and a controller 105. Two placement holes 102 are opened on the inner wall of the housing 101. A first motor 103 is installed on the outer wall of the housing 101. A round rod 104 is installed at the output end of the first motor 103. An inner housing 106 is movably sleeved inside the housing 101. A rotating plate 107 is arranged inside the inner housing 106. A circular ring block 108 is fixed inside the inner housing 106. A filter plate 109 is arranged at the bottom of the circular ring block 108. A diversion shell 110 is arranged at the bottom of the filter plate 109. The first motor 103 is electrically connected to the controller 105. One end of the round rod 104 close to the first motor 103 fixedly penetrates the outer surface of the rotating plate 107. One end of the round rod 104 close to the first motor 103 movably penetrates the outer wall of the inner housing 106. One end of the round rod 104 close to the first motor 103 movably penetrates the inner wall of the inner housing 106. The round rod 104 is movably sleeved between the two placement holes 102. The lower side of the inner housing 106 is in contact with the top of the housing 101. The outer surface of the rotating plate 107 is in contact with the inner wall of the inner housing 106. The circular ring block 108, the filter plate 109 and the diversion shell 110 are installed by screws. The filter plate 109 is movably sleeved inside the inner housing 106. The diversion shell 110 is movably sleeved inside the inner housing 106. The discharge end of the diversion shell 110 movably penetrates the bottom of the inner wall of the housing 101. The stirring mechanism 2 includes a cover plate 201. A second motor 202 is installed on the top of the cover plate 201. A connecting rod 203 is installed at the output end of the second motor 202. A plurality of stirring plates 204 are fixed on the outer surface of the connecting rod 203. The bottom of the cover plate 201 is installed on the top of the inner housing 106. The second motor 202 is electrically connected to the controller 105. The top end of the connecting rod 203 movably penetrates the bottom of the cover plate 201. Each stirring plate 204 is located inside the inner housing 106. A fixing block 3 is fixed on the outer wall of the housing 101. The controller 105 is installed on the outer surface of the fixing block 3.
[0027] The achieved effect is that when the p-chlorophenylglycine purification device needs to decolorize and filter the p-chlorophenylglycine solution, first connect the controller 105 to an external power supply. Then, put an appropriate amount of p-chlorophenylglycine solution and an appropriate amount of activated carbon particles into the inner shell 106. Next, install the cover plate 201 on the inner shell 106. At this time, the moving cover plate 201 will drive the second motor 202 to move, and the moving second motor 202 will also drive the connecting rod 203 and all the stirring plates 204 to move together. When the cover plate 201 is installed, directly use the controller 105 to start the second motor 202. At this time, the started second motor 202 will drive the connecting rod 203 to rotate, and the rotating connecting rod 203 will drive all the stirring plates 204 to rotate inside the inner shell 106, thereby accelerating the decolorization effect of the p-chlorophenylglycine solution. When the p-chlorophenylglycine solution is decolorized, use the controller 105 to turn off the second motor 202. At this time, the turned-off second motor 202, with the cooperation of the connecting rod 203, will stop all the stirring plates 204 from rotating. Then, remove the cover plate 201. At this time, the moving cover plate 201 will drive the second motor 202, the connecting rod 203, and all the stirring plates 204 to move together. When all the stirring plates 204 are moved out of the inner shell 106, first place the container for collecting the decolorized and filtered p-chlorophenylglycine solution directly below the discharge end of the diversion shell 110. Then, use the controller 105 to start the first motor 103. At this time, the started first motor 103 will drive the round rod 104 to rotate, and the rotating round rod 104 will drive the rotating plate 107 to rotate inside the inner shell 106. At the same time, the rotating rotating plate 107 will cause the activated carbon particles and the decolorized p-chlorophenylglycine solution to fall above the filter plate 109 and the circular ring block 108. Subsequently, under the action of the filter plate 109, the activated carbon particles will be filtered out. Then, the filtered p-chlorophenylglycine solution will enter the inner part of the diversion shell 110 and then enter the collection container from the discharge end of the diversion shell 110. When the rotating plate 107 rotates a certain angle (just convenient for the activated carbon particles and the p-chlorophenylglycine solution to enter above the filter plate 109), use the controller 105 to turn off the first motor 103. At this time, the turned-off first motor 103, with the cooperation of the round rod 104, will stop the rotating plate 107 from rotating. When all the filtered p-chlorophenylglycine solution has entered the collection container, the p-chlorophenylglycine solution can complete the decolorization and filtration operations.
[0028] Working principle: When the p-chlorophenylglycine purification device needs to decolorize and filter the p-chlorophenylglycine solution, first connect the controller 105 to an external power supply. Then, put an appropriate amount of p-chlorophenylglycine solution and an appropriate amount of activated carbon particles into the inner shell 106. Next, install the cover plate 201 on the inner shell 106. At this time, the moving cover plate 201 will drive the second motor 202 to move, and the moving second motor 202 will also drive the connecting rod 203 and all the stirring plates 204 to move together. When the cover plate 201 is installed, directly use the controller 105 to start the second motor 202. At this time, the started second motor 202 will drive the connecting rod 203 to rotate, and the rotating connecting rod 203 will drive all the stirring plates 204 to rotate inside the inner shell 106. At this time, the decolorization effect of the p-chlorophenylglycine solution can be accelerated. When the p-chlorophenylglycine solution is decolorized, use the controller 105 to turn off the second motor 202. At this time, the turned-off second motor 202, with the cooperation of the connecting rod 203, will stop all the stirring plates 204 from rotating. Then, remove the cover plate 201. At this time, the moving cover plate 201 will drive the second motor 202, the connecting rod 203 and all the stirring plates 204 to move together. When all the stirring plates 204 are moved out of the inner shell 106, first place the container for collecting the decolorized and filtered p-chlorophenylglycine solution directly below the discharge end of the diversion shell 110. Then, use the controller 105 to start the first motor 103. At this time, the started first motor 103 will drive the round rod 104 to rotate, and the rotating round rod 104 will drive the rotating plate 107 to rotate inside the inner shell 106. At the same time, the rotating rotating plate 107 will make the activated carbon particles and the decolorized p-chlorophenylglycine solution fall above the filter plate 109 and the circular ring block 108. Then, under the action of the filter plate 109, the activated carbon particles will be filtered out. Next, the filtered p-chlorophenylglycine solution will enter the inner part of the diversion shell 110 and then enter the collection container from the discharge end of the diversion shell 110. When the rotating plate 107 rotates a certain angle (just convenient for the activated carbon particles and the p-chlorophenylglycine solution to enter above the filter plate 109), use the controller 105 to turn off the first motor 103. At this time, the turned-off first motor 103, with the cooperation of the round rod 104, will stop the rotating plate 107 from rotating. When all the filtered p-chlorophenylglycine solution enters the collection container, the p-chlorophenylglycine solution can complete the decolorization and filtration operations.
