[0002] p-Chlorophenylglycine, also known as DL-p-chlorophenylglycine, has a melting point of 220-230℃. It is a toxic substance and should never be ingested. It is irritating to the eyes, respiratory system, and skin. Appropriate protective clothing should be worn when using p-chlorophenylglycine. Industrially, it is mainly used for the synthesis of pharmaceuticals. The industrial production of p-chlorophenylglycine requires feeding.

[0003] Currently, in the production of p-chlorophenylglycine, the raw materials need to be manually poured into a feeding hopper for feeding. The feeding hopper is used to discharge the material to the equipment. However, the current feeding equipment is not convenient for controlling the feeding of raw materials, and it is mostly fed in one go, resulting in uneven distribution of raw materials during the production process. Therefore, those skilled in the art have provided a feeding device for the production of p-chlorophenylglycine to solve the problems mentioned in the background art. Utility Model Content

[0022] Please see Figures 1-4 In this embodiment of the present invention, a feeding device for the production of p-chlorophenylglycine includes a discharge hopper 1 and a feeding hopper 2. A fixing plate 12 is fixedly connected to the left side of the feeding hopper 2, and a suction fan 11 is installed on the upper surface of the fixing plate 12. A suction pipe 4 is fixedly connected to the input end of the suction fan 11. The end of the suction pipe 4 away from the suction fan 11 is connected to the right side of the discharge hopper 1, and the output end of the suction fan 11 is connected to the left side of the feeding hopper 2. Two baffle brushes 14 are installed on the inner wall of the feeding hopper 2. The baffle brushes 14 can fill the gap between the feeding shaft 16 and the feeding hopper 2, thereby preventing the feeding shaft 16 from stopping. To prevent material leakage, two bearings 13 are fixedly embedded in the inner wall of the feeding hopper 2. The inner rings of the two bearings 13 are jointly mounted with a feeding shaft 16. Multiple feeding slots 15 are opened on the outer surface of the feeding shaft 16. A drive motor 18 is installed on the back of the feeding hopper 2. The output end of the drive motor 18 is connected to one end of the feeding shaft 16. When the suction fan 11 operates in conjunction with the suction pipe 4, the raw material in the discharge hopper 1 is transported to the feeding hopper 2. The drive motor 18 on the feeding hopper 2 is controlled to drive the feeding shaft 16 to rotate. The feeding shaft 16, in conjunction with the feeding slots 15, slowly feeds the material, thereby facilitating the control of the feeding device and ensuring the uniformity of the feeding.

[0023] A protective cover 20 is hinged to the upper surface of the feeding hopper 2. A handle 10 is fixedly connected to the front of the protective cover 20. The protective cover 20 can protect the feeding hopper 2, and the handle 10 can easily open and close the protective cover 20. A display window 9 is provided on the front of the feeding hopper 2. The two material blocking brushes 14 are in contact with the feeding shaft 16 on their close sides. The display window 9 allows for easy observation of the raw materials in the feeding hopper 2. The material blocking brushes 14 can fill the gap between the feeding shaft 16 and the feeding hopper 2, thereby preventing material leakage when the feeding shaft 16 stops. A mounting base 8 is fixedly connected to the bottom surface of the feeding hopper 2. Two sets of mounting holes 7 are provided on the upper surface of the mounting base 8. The feeding hopper 2 in the feeding device can be easily installed at the feed inlet of the processing equipment by the cooperation of the mounting base 8 and the mounting holes 7.

[0024] A cover 17 is screwed onto the back of the feeding hopper 2. A heat dissipation window 19 is provided on the back of the cover 17 to protect the drive motor 18. The heat dissipation window 19 facilitates heat dissipation of the cover 17. A protective box 5 is fixedly connected to the front of the feeding hopper 1. A control switch 6 is installed inside the protective box 5. The protective box 5 provides protection for the control switch 6. The control switch 6 is electrically connected to the drive motor 18 and the suction fan 11 through wires. The drive motor 18 is a servo motor, which can control the speed to adjust the feeding speed. Two support legs 3 are fixedly connected to the left side of the feeding hopper 1 to assist in supporting the feeding hopper 1.

[0025] The working principle of this utility model is as follows: When in use, the feeding hopper 2 of the feeding device is first fixed to the feed inlet of the processing equipment using the mounting base 8, so that the discharge hopper 1 contacts the ground with the cooperation of the support leg 3. The power supply of the feeding device is turned on, and the raw material of p-chlorophenylglycine is poured into the discharge hopper 1. The suction fan 11 on the feeding hopper 2 is started. The suction fan 11 operates in conjunction with the suction pipe 4 to transport the raw material in the discharge hopper 1 to the feeding hopper 2. The drive motor 18 on the feeding hopper 2 is controlled to drive the feeding shaft 16 to rotate. The feeding shaft 16 cooperates with the feeding trough 15 to slowly feed the material, thereby facilitating the control of the feeding device and ensuring the uniformity of feeding.
