Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production and processing, in particular to a high-efficiency fertilizer drying device for fertilizer production. Background Art

[0002] Fertilizer is an essential resource in agricultural production. Made through chemical and physical methods, it contains the nutrients necessary for crop growth. Fertilizer production is a complex process involving a variety of raw materials and chemical reactions. Generally speaking, the fertilizer production process includes raw material preparation, chemical reactions, product separation and purification, drying, and granulation. Different types of fertilizers require different production processes. For example, hydrogen fertilizer production often uses the synthetic ammonia method, while phosphate fertilizer production often uses phosphate rock as raw material through acid hydrolysis. Potash fertilizer production relies on the mining and processing of potash resources.

[0003] In the existing technology, drying devices are used in fertilizer production. When the fertilizer is heated and dried, water vapor and other gases are generated. Most drying devices have air outlets to allow water vapor to dissipate on its own. At the same time as the water vapor is dissipated, other gases are also discharged. It is not ruled out that some of these gases may cause harm to the health of workers, and the self-emission of water vapor will affect the drying efficiency of the fertilizer.

[0004] For this reason, a high-efficiency drying device for fertilizer production is proposed. Utility Model Content

Two L-shaped blocks are threadedly mounted on the outer wall of the bidirectional screw, and the two L-shaped blocks are slidably mounted on the inner wall of the fixing shell. The front end of the bidirectional screw extends outside the fixing shell, and a twist handle is mounted on the surface of the bidirectional screw at the extended end.

[0011] Furthermore, a contact plate is installed at the bottom of the two L-shaped blocks, and the contact plate is in contact with the drying box and the activated carbon box.

[0012] Furthermore, the number of the supporting legs is set to four, and the four supporting legs are distributed in a rectangular shape at the bottom of the insulation barrel.

[0013] The beneficial effects of the utility model are as follows:

[0014] The utility model is provided with a drying box, an activated carbon box and a resistance plate.

The heating barrel and the motor are started, the heating barrel heats the fertilizer, the motor drives the stirring rod to rotate, and the stirring rod stirs the fertilizer, so that the fertilizer is fully exposed to heat, thereby improving the drying efficiency of the fertilizer. During the heating and drying process of the fertilizer, water vapor and other gases are generated, and the exhaust fan is started. With the cooperation of the rectangular tube, the air duct and the air hood, the water vapor and other gases are accelerated and drawn. The gas passes through the two drying boxes in advance.

[0026] like Figure 1-4 As shown, the filtering mechanism 10 includes a rectangular tube 1001, which is mounted on the top of the mounting plate 5.
