[0002] Phosphates are a class of salt compounds containing phosphorus elements, usually referring to oxygen-containing salts formed by the combination of phosphorus and oxygen. Phosphates are widely present in nature and are important components in organisms, participating in many biochemical processes. In industry and agriculture, phosphates are also widely used. They are used as fertilizers because phosphorus is one of the key nutrients required for plant growth. In addition, phosphates are also used in fields such as food processing, water treatment, and detergents. When producing phosphates, grinding devices are used to grind them into powder particles for easy mixing with other materials.

[0003] For example, a grinding disc for phosphate grinding with the publication number of CN211070271U in the prior art improves the sealing performance between the grinding seat and the lower grinding disc, forms a sealed space, protects the production environment, and avoids waste of phosphates, thus protecting the production environment and avoiding waste of phosphates.

[0004] However, the above prior art still has the following problems when in use: After long-term use, a large amount of phosphate materials will remain between the upper grinding disc and the lower grinding disc. When the staff disassembles the upper grinding disc and the lower grinding disc for cleaning, the phosphate materials will fall and float into the air, resulting in environmental pollution and affecting the health of the staff. Based on this, the utility model provides a grinding device for phosphate production that can automatically clean the phosphate residues. Summary of the Utility Model

[0025] Refer to the attached drawings of the specification Figures 1-5, the present utility model provides a grinding device for phosphate production, including a tank body 1. Inside the tank body 1, there are an upper grinding disc 2 and a lower grinding disc 3 for grinding phosphate. The upper grinding disc 2 is arranged on the top of the lower grinding disc 3. At the top end of the tank body 1, there is a driving assembly 4 for driving the upper grinding disc 2 to rotate. The lower grinding disc 3 is detachably fixed to the inner wall of the tank body 1;

[0026] Above the upper grinding disc 2, there is a cleaning assembly 5. The cleaning assembly 5 includes an annular plate 501. At the bottom end of the annular plate 501, a plurality of spray nozzles 502 are fixedly arranged. The plurality of spray nozzles 502 are connected to a high-pressure air pump 503 through a hose. On both sides of the top end of the annular plate 501, electric push rods 504 are fixedly arranged. The top ends of the electric push rods 504 penetrate through the top of the tank body 1. The high-pressure air pump 503 is fixed at the rear end of the tank body 1;

[0027] In order to facilitate the staff to observe the inside of the tank body 1, an opening 6 is provided at the front end of the tank body 1.
