[0022] A grinding groove 9 is installed on the inner bottom of the processing box 1. A V-shaped guiding plate 8 fixedly connected to the inner rear side wall of the processing box 1 is located between the first grinding rollers 5 and the grinding groove 9. The V-shaped guiding plate 8 can play a guiding role for the chemical raw materials to make them fall into the grinding groove 9. And both sides of the upper end of the V-shaped guiding plate 8 are inclined inwards, which can make the chemical raw materials move towards the middle of the V-shaped guiding plate 8, so that the chemical raw materials can fall into the grinding groove 9, avoiding the direct fall of the chemical raw materials into the processing box 1. A closing door 16 is installed on the front side wall of the processing box 1. Opening the closing door 16 can clean and overhaul the inside of the processing box 1. A transparent observation window can also be installed through the closing door 16 to facilitate the viewing of the processing state inside the processing box 1.

A second grinding roller 13 driven by a third driving motor is installed on the side wall of the L-shaped mounting plate 12. The second grinding roller 13 abuts against the inner bottom of the grinding groove 9, which is beneficial for fully grinding the chemical raw materials. A protective cover covering the outside of the third driving motor is fixedly connected to the side wall of the L-shaped mounting plate 12 to prevent the chemical raw materials from affecting the normal operation of the third driving motor. A collecting box 15 is arranged below the processing box 1. A discharge pipe 10 opposite to the collecting box 15 is installed through the bottom of the grinding groove 9. The inner bottom of the grinding groove 9 is inclined towards the discharge pipe 10, which is beneficial for discharging the chemical raw materials. A control valve is installed on the discharge pipe 10 to control the discharge operation, so that the fully ground chemical raw materials are centrally collected in the collecting box 15.

[0024] The functional principle of the present utility model can be described through the following operation modes:

[0025] In the present utility model, when the chemical raw material grinding device for chemical industry works, rotate the sealing cover 4 to open the feeding funnel 2, and add the chemical raw materials into the processing box 1 through the feeding funnel 2. Under the guiding action of the two L-shaped guide plates 6, the chemical raw materials fall into the two first grinding rollers 5 and are initially crushed and ground by the two first grinding rollers 5. Under the guiding action of the V-shaped guide plate 8, the initially crushed and ground chemical raw materials can fall into the grinding groove 9. The V-shaped guide plate 8 can protect the second driving motor 11. The second driving motor 11 drives the L-shaped mounting plate 12 to rotate, so that the second grinding roller 13 rotates along the grinding groove 9. At the same time, the third driving motor drives the second grinding roller 13 to roll. Furthermore, the second grinding roller 13 can rotate and roll at the same time to further grind the chemical raw materials in the grinding groove 9. After the chemical raw materials in the grinding groove 9 are fully ground, open the control valve on the discharge pipe 10, and the fully ground chemical raw materials can fall into the collecting box 15 through the discharge pipe 10 for centralized collection, which is beneficial for the staff to take them out.
