Description

Technical Field

[0001] This utility model relates to the field of granulation equipment technology, and more specifically, to a roller press dry granulation equipment with a cooling water channel. Background Technology

[0002] The dry granulation method is a relatively simple fertilizer production process. This method mainly involves mechanically mixing and grinding raw materials in a solid state, and then directly producing granular fertilizer using specific equipment and technology. The dry granulation method is characterized by the absence of complex chemical reactions, resulting in high production efficiency. This process mainly includes steps such as raw material crushing, screening, mixing, granulation, and packaging. During granulation, high temperature and high pressure techniques are used to make the raw material particles compact for easy use. Fertilizer produced by roller pressing will be at high temperatures; for example, the heat generated by friction during continuous granulation on the forming rollers will be conducted to the fertilizer. This warm fertilizer is not conducive to subsequent heat preservation, and the high temperature makes it easy for the fertilizer to absorb moisture from the air, leading to clumping and mold growth. Therefore, we propose a roller pressing dry granulation device with a cooling water channel. Utility Model Content

The servo motor 22 is started to drive one granulation roller 21 and one spur gear 23 to rotate. The meshing transmission between the two spur gears 23 drives the two granulation rollers 21 to rotate. The raw material is granulated by the two granulation rollers 21, and the formed granules fall onto the top surface of the cooling box 4. In addition, the granules will be hot during granulation.

The inner cavity of the cooling box 4 utilizes the low temperature of the cooling water in the cooling box 4 and the particles on the cooling box 4 for heat exchange, thereby cooling the particles. In addition, the water in the cooling box 4 flows back to the inner cavity of the water tank 10 from the outlet pipe 7, the water collection box 8 and the return water pipe 9. Finally, when the temperature sensor 17 detects that the temperature of the cooling water in the inner cavity of the water tank 10 has risen and is insufficient for heat exchange and cooling, the semiconductor cooling chip 14 is energized to generate a low temperature on its cooling surface. The low temperature is conducted to the cooling water by the heat-conducting fins 15 to cool the cooling water. In addition, the heat generated by the semiconductor cooling chip 14 during operation is dissipated through the heat dissipation fins 16.
