Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, specifically to a high-efficiency drying device for fertilizer production. Background Technology

[0002] Chemical fertilizers, also known as chemical fertilizers, are essential nutrients for the growth and development of any natural or synthetic plant. There are many types and brands of fertilizers on the market. Based on their composition, they can be divided into inorganic fertilizers and organic fertilizers. Fertilizers are usually applied directly to the soil or sprayed on the leaves. In the process of producing chemical fertilizers, drying equipment is required to dry them.

[0003] In the prior art, Chinese patent application number 202021907554.7 discloses a high-efficiency fertilizer drying device for fertilizer production, which includes two vertical plates. A horizontally arranged top plate is fixedly installed between the tops of the two vertical plates, and a feed hopper is fixedly installed on the top of the top plate. A horizontally arranged shaking plate is slidably installed between the two vertical plates. A drive box is provided on one side opposite to the two vertical plates. A vertically arranged lifting rod is slidably installed on the top of the drive box. The top of the lifting rod is fixedly connected to the shaking plate, and the lifting rod is slidably connected to the drive box. The drive box is provided with a lifting structure for the lifting rod to move up and down. A compression spring is sleeved on the lifting rod, and the compression spring is located between the shaking plate and the drive box. This utility model realizes the up-and-down shaking and lateral rolling of fertilizer granules, so that the fertilizer granules are heated evenly, greatly improving the drying effect and the drying uniformity is high. It is easy to promote. However, the water vapor generated when heating the fertilizer granules is not easy to escape from the drying box, which affects the drying efficiency of the fertilizer granules. Moreover, the dried fertilizer granules are easily turned into powder when they collide during rolling, which affects the quality of the fertilizer.

[0012] Preferably, the auxiliary drying mechanism includes a positioning frame, a spreading plate, a scraper, a drive motor, and a tilting frame. The positioning frame is fixed on both sides of the first mounting frame and the second mounting frame, respectively. The spreading plate, the scraper, and the tilting plate are arranged on the positioning frame from top to bottom. The drive motor is installed on one side of the positioning frame. The output shaft of the drive motor is connected to one end of the tilting frame, and the other end of the tilting frame is rotatably connected to the positioning frame through a bearing.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Fertilizer granules are fed into the drying chamber through the feed inlet and fall onto the conveyor belt of the first mounting frame. The fertilizer is heated and dried by the heating component. After the fertilizer moves to one end of the conveyor belt, it falls onto the conveyor belt of the second mounting frame and the guide table in sequence. During the feeding process of the conveyor belt, the fertilizer granules can be turned over to improve the drying efficiency of the fertilizer.

[0016] 2. When the fertilizer granules move on the conveyor belt, the spreading plate of the auxiliary drying mechanism can flatten the fertilizer, preventing the fertilizer granules from accumulating and affecting the drying of the fertilizer at the bottom.
