AI Technical Summary
In the current kaolin preparation process, when the filter cake is directly fed into the crushing equipment, it is easy to cause the crushing roller to run idle, which increases the preparation cost.
A pulverizing device comprising a crushing chamber and a grinding chamber was designed. The filter cake is initially crushed by the crushing components in the crushing chamber and then conveyed to the grinding chamber by a screw conveyor shaft, thus preventing the filter cake from directly entering the grinding chamber. The grinding components then further pulverize the filter cake using the grinding rollers.
This effectively avoids the idling of the crushing roller, improves the crushing efficiency of the filter cake, and reduces the preparation cost.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of kaolin production equipment, and in particular to a crushing device for kaolin preparation.
[0002] The production process of kaolin is as follows: First, the raw material is crushed by a crusher. Then, the crushed raw material is screened, pulped, settled and dried. After sedimentation, the raw material is filtered to form a filter cake. Before drying the raw material, the filter cake needs to be crushed again to improve the efficiency of the subsequent drying process and to avoid the presence of large kaolin lumps in the processed kaolin.
[0003] Currently available filter cake crushing equipment involves feeding the filter cake into the feed inlet of the crushing equipment, where it is then crushed by the crushing rollers inside. However, this method has a drawback: if the filter cake is directly fed into the crushing equipment, the crushing rollers may idle during the crushing process due to the large size of the filter cake. Therefore, a preliminary crushing device is needed to break the filter cake into smaller pieces before feeding it into the crushing equipment, which increases the cost of kaolin production. Background Technology
[0004] Kaolin is a type of rock primarily composed of kaolinite group minerals. Kaolinite is a mineral aggregate mainly composed of silicate minerals, possessing a specific crystal structure and chemical composition. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a pulverizing device for kaolin preparation, which solves the problem that, in existing technologies, after the filter cake is put into the pulverizing device, the pulverizing roller will run idle during the pulverizing process because the filter cake is in a large block shape.
[0006] According to an embodiment of this utility model, a pulverizing device for kaolin preparation includes: a base, a support plate, a crushing box, and a grinding box. The grinding box is fixed to the top of the base by a bracket. A support column is provided on one side of the base, and the support plate is horizontally fixed to the top of the support column.

[0019] By setting up a crushing chamber 2, the crushing components inside the crushing chamber 2 will crush the filter cake added from the first feed hopper 6. Then, the first motor 8 will drive the screw conveyor shaft 7 to rotate, and the screw conveyor shaft 7 will transport the crushed filter residue to the discharge pipe 9. Then, the discharge pipe 9 will transport the filter residue to the second feed hopper 13. The crushing components in the crushing chamber will crush the filter residue, thereby preventing the disadvantage of directly adding the filter cake into the crushing chamber, which would cause the crushing components to run idle due to the filter cake being too large. That is, through the above setting, the efficiency of filter cake crushing can be effectively improved.
[0020] Furthermore, the crushing assembly includes: two crushing rollers 14 and a second motor. The two crushing rollers 14 are symmetrically and rotatably arranged in the crushing chamber 5. The second motor is arranged on the side wall of the crushing box 2 and is used to drive the two crushing rollers 14 to rotate. The pulverizing assembly includes: two pulverizing rollers 23 and a third motor. There are two pulverizing rollers 23, which are rotatably arranged in the pulverizing chamber. The third motor is arranged on the side wall of the pulverizing box 1 and is used to drive the pulverizing rollers 23 to rotate. There are two second motors and two third motors, which are used to drive the corresponding crushing rollers 14 or pulverizing rollers 23 respectively.
[0021] Furthermore, such as Figure 1 As shown, the discharge pipe 9 is inclined, with its end near the second feed hopper 13 being the lower end, which facilitates the conveying of the crushed filter residue into the second feed hopper 13.
[0022] like Figure 2 As shown, the discharge pipe 9 is equipped with an opening and closing component for opening and closing, which is used to control the opening size of the discharge pipe 9.
[0023] Specifically, the opening and closing assembly includes: an opening and closing plate 15, a limiting rod 16, and a snap-fit component. The opening and closing plate 15 is slidably connected in a direction perpendicular to the discharge pipe 9. The limiting rod 16 is disposed on the side wall of the discharge pipe 9 and is perpendicular to the discharge pipe 9. One end of the opening and closing plate 15 extends out of the discharge pipe 9. The snap-fit component is fixed to the end of the opening and closing plate 15 that extends out of the discharge pipe 9. The limiting rod 16 is provided with a plurality of limiting grooves 17 on the side wall near the snap-fit component. The snap-fit component is used to snap into the limiting grooves 17.
[0024] The snap-fit component includes: a mounting base 18, a spring 20, a limiting pin 21, and a push rod 22. The mounting base 18 is fixed to the end of the opening and closing plate 15. The mounting base 18 has a mounting groove on the side near the limiting rod 16. The side wall of the mounting base 18 has a sliding groove 19 that communicates with the mounting groove. The spring 20 is disposed in the mounting groove. One end of the limiting pin 21 is slidably disposed in the mounting groove, and the limiting pin 21 is inserted into the limiting groove 17 under the elastic force of the spring 20. One end of the push rod 22 is slidably connected to the sliding groove 19, and the end of the push rod 22 is fixedly connected to the side wall of the limiting pin 21.
[0025] By setting several limiting grooves 17 on the side wall of the limiting rod 16, and the several limiting grooves 17 being evenly distributed along the extension direction of the limiting rod 16, it is convenient to adjust the limiting pin 21 to be inserted into the limiting groove 17 at different positions, so that the opening and closing plate 15 can be fixed at different positions, thereby adjusting the opening size of the discharge pipe 9 and controlling the amount of material discharged from the discharge pipe 9 to the second feed hopper 13 per unit time; specifically, when adjusting the sliding of the opening and closing plate 15 relative to the discharge pipe 9, first push the push rod 22 to push the limiting pin 21 out of the limiting groove 17, and then push and pull the opening and closing plate 15 to slide relative to the discharge pipe 9.
