Description

Technical Field

[0001] The utility model relates to the technical field of selenium-rich fertilizer production, in particular to a raw material screening device for selenium-rich fertilizer production. Background Art

[0002] Selenium-rich fertilizer is a special fertilizer that contains a high level of selenium. Its main function is to supplement the selenium required for plant growth, thereby increasing the yield and quality of crops and enhancing the stress resistance of crops. When producing selenium-rich fertilizer, the raw materials need to be put into a fermentation tank and compound bacteria are added for fermentation, and then the fermented raw materials are added to a grinder for crushing; and the raw materials used for production usually include animal manure, plant powder, yeast selenium powder, beneficial bacteria, etc. Therefore, during the crushing process, the particle size of the raw materials will change differently, which may cause uneven distribution of selenium. Therefore, a screening device is needed to separate raw materials with different particle sizes, so that the distribution of selenium is more uniform, thereby improving the effect of selenium-rich fertilizer.

[0003] According to the search, Chinese patent literature, announcement number: CN215031086U, discloses a raw material screening device for the production of selenium-rich organic selenium fertilizer. The screen box can be sealed by the set cover plate, block, hanging ring and hook to prevent the fertilizer from being scattered during screening. The cover plate is covered on the top of the screen box by the limit of the block, and the hanging ring is pulled. The first spring extends and buckles the hanging ring on the hook. The first spring resets and tightens the hanging ring, so that the hanging ring presses the cover plate to reliably limit the cover plate, increasing the practicality of the device. However, in actual use, the device is inconvenient for adding raw materials and collecting different raw materials after separation, which reduces the overall working efficiency of the device; at the same time, the screen mesh of the device will also be blocked by some impurities after being used for a period of time, thereby reducing the overall screening efficiency.
