DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, the embodiment of the utility model is explained in detail below in conjunction with the drawings, but the example described in the utility model is a part of the embodiment of the utility model, not all the embodiment.

[0021] As Figures 1 to 4 Shown, a kind of self-circulation dry crushing mechanical mill, including: honeycomb mill 1, C type pipe 2, first collector 3 and second collector 4.

[0022] Specifically, as Figure 2As shown, the honeycomb mill 1 includes a dispersion chamber 11, a grinding chamber 12 and a sorting chamber 13 arranged sequentially from bottom to top and interconnected. The dispersion chamber 11 is used to initially disperse the material entering the honeycomb mill 1, and the grinding chamber 12 can realize the functions of deagglomeration, crushing, shaping and modification of the material.

[0023] Specifically, such as Figures 1 to 4 As shown, the sorting chamber 13 is equipped with a grading impeller 14. As a conventional solution, the grading impeller 14 is directly driven by a motor, and the motor is located at the top of the sorting chamber 13 and the top of the honeycomb mill 1. The grading impeller 14 divides the sorting chamber 13 into upper and lower sections. The first collector 3 is connected to the upper section of the sorting chamber 13 through a pipe. The side wall of the lower section of the sorting chamber 13 is provided with a return pipe 131 corresponding to the periphery of the grading impeller 14. The end of the return pipe 131 extends to the outside of the sorting chamber 13 and is connected to the C-shaped pipe 2 through a longitudinal pipe 132.

[0024] Specifically, in combination Figures 1 to 3 As shown, the C-shaped tube 2 is fitted onto the outer periphery of the dispersion chamber 11.

[0025] Specifically, in combination Figures 1 to 3 As shown, one end of the C-shaped tube 2 is provided with an air inlet pipe 21, and the air inlet pipe 21 is connected to a feed pipe 22.

[0026] Specifically, such as Figure 1 As shown, the other end of the C-shaped pipe 2 is provided with a three-way pipe 5. The other two ends of the three-way pipe 5 are respectively connected to the second collector 4 and the dispersion chamber 11. The end connected to the second collector 4 is provided with a first control valve 51, and the end of the three-way pipe 5 connected to the dispersion chamber 11 is provided with a second control valve 52. The pipe between the second control valve 52 and the dispersion chamber 11 is provided with a secondary air hole 53, and the secondary air hole 53 is provided with a valve.

[0027] Both the first collector 3 and the second collector 4 are negative pressure collection devices. Specifically, both the first collector 3 and the second collector 4 are dust collectors.

[0028] There are two main working modes during production: one is crushing and deagglomeration, and the other is shaping.

[0029] like Figures 1 to 3As shown, during the crushing and depolymerization, the first control valve 51 is closed, and the first collector 3 is started, which generates negative pressure inside the honeycomb mill 1, and the hot air enters the inlet pipe 21 through the negative pressure conveying, and the material raw material is put into the inlet pipe 21 at the same time. Specifically, the temperature of the hot air is 200-500°C. The material and the hot air enter the C-shaped pipe 2 at the same time after mixing in the inlet pipe 21, and the material can be preheated by the hot air in this process; the mixed material and the hot air finally enter the dispersion bin 11 from the three-way pipe 5, and the material is preliminarily dispersed in the dispersion bin 11. The dispersed material automatically rises to the grinding bin 12 along with the negative pressure airflow, and the grinding bin 12 performs powder grinding, depolymerization and shaping treatment on the entering material. The surface modification of the material can also be realized by adding the modifier in this process. The processed material enters the lower section of the sorting bin 13, and finally the small-particle-size material enters the inside of the classification impeller 14 through the gap between the blades of the classification impeller 14, and smoothly enters the upper section of the sorting bin 13, and then smoothly enters the inside of the first collector 3 through the pipeline to achieve the purpose of collecting small-particle-size material. During the classification of the material by the classification impeller 14, under the action of the centrifugal force generated by the rotation of the classification impeller, the large-particle-size material cannot enter the inside of the classification impeller and is cut tangentially to enter the return pipe 131, and then flows back to the C-shaped pipe 2 through the longitudinal pipeline 132, and finally enters the dispersion bin 11, the grinding bin 12 and the sorting bin 13 again for cyclic crushing and classification treatment, until the material raw material is processed or the raw material is stopped. In the process of multiple cycles, the material is continuously contacted with the hot air, so that the drying effect of the material is better.

[0030] As shown in Figure 1 , Figure 2 and Figure 4 , during the shaping, the first control valve 51 is closed, the valve of the secondary air hole 53 is closed, the second control valve 52 is opened, and the shaped material enters the grinding bin 12 for cyclic shaping. After the shaping is completed, the feeding is stopped, the first control valve 51 is opened, the valve of the secondary air hole 53 is opened, and the second control valve 52 is closed. The shaped material enters the second collector 4 for finished product collection, and the debris in the shaping process is collected by the first collector 3.

[0031] The above processing method can realize the cyclic crushing, depolymerization and shaping of the material, and the overall structure of the system is simple and the manufacturing cost is lower.
