[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a chlorination device for producing 3,4-dichlorotrifluorotoluene, comprising:

[0023] A barrel body 1, a lower hopper 4 is provided through the top of the barrel body 1, a liquid adding pipe 3 is provided through one side of the barrel body 1, the liquid adding pipe 3 is located below the grinding bucket 8, a liquid discharge pipe 2 is provided through the bottom end of the side of the barrel body 1, a valve is installed on the liquid discharge pipe 2, a bracket 19 is fixedly installed at the bottom of the barrel body 1, and a stirring assembly is provided in the barrel body 1;

[0024] The stirring assembly includes a motor 5, a shaft 6 and a plurality of stirring plates 7. The motor 5 is fixedly arranged at the bottom of the barrel body 1. The output end of the motor 5 penetrates the bottom of the barrel body 1 and is rotatably arranged. The shaft 6 is fixedly arranged at the output end of the motor 5. The plurality of stirring plates 7 are fixedly arranged on the shaft 6. The plurality of stirring plates 7 are evenly distributed. The motor 5 can drive the plurality of stirring plates 7 to rotate through the shaft 6, so that the solution can be fully stirred.

[0025] The grinding assembly includes a grinding bucket 8, a conical grinding plate 9, a guide bucket 12, a fixed plate 13, a lifting plate 14 and a reciprocating screw rod 15. The grinding bucket 8 is fixedly arranged on the inner wall of the barrel body 1, and the conical grinding plate 9 is arranged in cooperation with the grinding bucket 8. The grinding bucket 8 is arranged in a bucket shape. The conical grinding plate 9 slides against the inner side of the grinding bucket 8, which can grind the catalyst and crush the large pieces of catalyst;

[0026] A rectangular column 10 is fixedly arranged on the top of the shaft 6, and a rectangular groove 11 is arranged at the bottom of the conical grinding plate 9. The rectangular column 10 and the inner wall of the rectangular groove 11 are slidably arranged against each other, so that the motor 5 can drive the rectangular column 10 to rotate through the shaft 6, and the rectangular column 10 can drive the conical grinding plate 9 to rotate through the rectangular groove 11, and the rectangular column 10 does not affect the up and down movement of the conical grinding plate 9;

[0027] The guide hopper 12 is fixedly arranged on the top of the conical grinding plate 9. The guide hopper 12 can guide the catalyst so that the catalyst flows between the conical grinding plate 9 and the grinding bucket 8. The fixed plate 13 is fixedly arranged on the top of the guide hopper 12. The reciprocating screw rod 15 is fixedly arranged on the inner top of the barrel body 1. The reciprocating screw rod 15 penetrates the lifting plate 14 and is arranged in cooperation, so that the lifting plate 14 can move back and forth on the reciprocating screw rod 15 while rotating.

The limit blocks 18 limit the fixed plate 13. The two guide rods 16 are movably arranged through two springs 17 respectively.

[0029] The detailed working process of the utility model is as follows:

[0030] 1. When in use, the staff first injects the raw material into the barrel body 1 from the liquid adding pipe 3, and then pours the catalyst from the lower hopper 4 into the barrel body 1, and then starts the motor 5. The motor 5 drives the rectangular column 10 to rotate through the shaft 6, and the rectangular column 10 drives the conical grinding plate 9 to rotate through the rectangular groove 11. The conical grinding plate 9 drives the fixed plate 13 to rotate through the guide hopper 12. The fixed plate 13 drives the lifting plate 14 to rotate through two guide rods 16. The lifting plate 14 rotates up and down in a circular motion through the reciprocating screw rod 15, thereby driving the conical grinding plate 9 to rotate up and down in a circular motion;

[0031] 2. When the lifting plate 14 drives the conical grinding plate 9 to move upward and separate from the grinding bucket 8, the catalyst can flow downward to between the conical grinding plate 9 and the grinding bucket 8. When the conical grinding plate 9 rotates downward and rotates against the grinding bucket 8, the two springs 17 are squeezed to grind and crush the catalyst. The ground and crushed catalyst will fall into the raw material below in a reciprocating cycle. At the same time, the shaft 6 can drive several stirring plates 7 to rotate to fully stir the solution.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
