DETAILED DESCRIPTION

Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0036] The crushing gear 7 is welded at the shaft end surface of the crushing roller 6 penetrating out of the feed hopper 1, and the two crushing gears 7 are engaged.

[0037] The crushing motor 8 is stably installed on the surface of the feed hopper 1 and is fixedly connected with the crushing roller 6 through the output shaft.

[0038] The feed hopper 1 and the crushing bin 2 are connected through the feed pipe 9.

[0039] The booster air pump 10 is connected through the air inlet pipe between the booster air pump 10 and the feed pipe 9, high-pressure gas is blown into the inside of the feed pipe 9, a certain impact force is provided for the material, and the material is prevented from being blocked in the feed pipe 9.

[0040] A plurality of booster air injection holes 11 are obliquely installed on the side surface of the crushing bin 2.

[0041] The ascending air pipe 12 is connected at the bottom of the crushing bin 2 and is used for providing ascending airflow.

[0042] The top of the crushing bin 2 is provided with a refining crushing bin 4, the inside of the refining crushing bin 4 is provided with a dispersion block 5 for dispersing the ascending material in the crushing bin 2, the refining crushing bin 4 and the crushing bin 2 are connected through the communication pipe 13, the material enters the crushing bin 2, and under the pushing of the high-pressure airflow injected from the booster air injection hole 11, the material is spirally rotated, the material is crushed by mutual collision and friction in the middle part of the crushing bin, and the crushed material is sent into the refining crushing bin 4 by the ascending airflow injected in the ascending air pipe 12.

[0043] The fixed frame 14 is fixed in the inside of the communication pipe 13.

[0044] The rotating shaft 15 can rotate on the top of the fixed frame 14 and is fixedly connected with the dispersion block 5.

[0045] Several wind deflector blades 16 are evenly installed on the top of the dispersion block 5.

[0046] The dispersing blades 17 are evenly dispersed at the bottom of the dispersing block 5 and fixed at an angle. The conical design of the dispersing block 5 prevents the material from adhering to the bottom of the dispersing block 5 under the blowing of the rising airflow, thereby improving the utilization rate of the material.

[0047] The fine jet nozzles 18 are evenly distributed on the side wall of the fine grinding chamber 4. The fine jet nozzles 18 blow out high-pressure airflow, which drives the dispersing blades 17 to rotate the dispersing block 5.

[0052] The precision sodium bicarbonate airflow pulverizing and classifying device provided by this utility model involves the following steps: Material enters the feed hopper 1 and is pulverized by the crushing roller 6, breaking down large pieces and clumps. Driven by the booster pump 10, it is fed into the pulverizing chamber 2 through the feed pipe 9. Propelled by the high-pressure airflow from the booster jet 11, the material rotates in a spiral motion. The material collides and rubs against each other in the center of the pulverizing chamber, resulting in further pulverization. The rising airflow from the rising air pipe 12 then sends the pulverized material into the refining pulverizing chamber 4. The refining jet 18 blows out high-pressure airflow, which drives the dispersing blades 17 to rotate the dispersing blocks 5. The dispersing blades 17 further disperse the material entering the pulverizing chamber 2. Because the gas pressure inside the refining jet 18 is higher and the space inside the refining pulverizing chamber 4 is smaller, the material can be pulverized more finely. Finally, it is classified by the classifying wheel 20 and collected centrally by the cyclone separator 3.
