Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural processing, and particularly relates to a production equipment and method for medium and trace element fertilizers. Background Art

[0002] The nutrient elements required by plants are divided into macronutrients (nitrogen, phosphorus, potassium), secondary nutrients (calcium, magnesium, sulfur) and micronutrients (iron, boron, manganese, zinc, etc.). Medium and trace element fertilizers are fertilizers that supplement these secondary and micronutrients.

[0003] Compared with traditional fertilizers, medium and trace element fertilizers usually need to add a variety of raw materials to meet the addition of a variety of medium and trace elements. The production process is usually raw material processing, formula design, additive mixing, drying and screening, and finished product packaging. The characteristics of medium and trace element fertilizers make the most important production link the additive mixing link. In the production process of traditional medium and trace element fertilizers, after the formula is usually determined, the raw materials are directly poured into the mixing equipment according to the formula ratio. This production method not only wastes raw materials, but also generates a large amount of dust, pollutes the environment and is easy to cause health damage to operators, and may also cause serious accidents such as dust explosion.

The fan 4 can blow air into the feeding mechanism 3 through the feeding air inlet 31. The raw materials can enter the mixing tank 1 from the feeding outlet 32 through the material passing ring 22. The feeding air inlet 31 is arranged above the feeding outlet 32. The air blown by the fan 4 can assist the raw materials to enter the mixing tank 1. The material passing ring 22 is connected to the filter housing 21, and the fan 4 can suck air from the filter housing 21, so that the dust generated by the raw materials entering the mixing tank 1 through the material passing ring 22 can be sucked by the dust collecting port 221 on the material passing ring 22, and is adsorbed on the outer wall of the filter cartridge 23 after entering the filter housing 21. The top of the filter cartridge 23 is open and the bottom is solid. At this time, the air flow direction is from the material passing ring 22 to the filter cartridge 23. The dust is adsorbed on the outer wall of the filter cartridge 23, and the filtered air is extracted by the fan 4 and blown towards the feeding mechanism 3 through the feeding air inlet 31. The raw materials entering the mixing tank 1 are stirred and mixed by the stirring paddle 52. During this process, the rotation of the stirring shaft 51 can also drive the second driving gear 54 to rotate. The rotation of the second driving gear 54 can drive the driven gear 231 to rotate, thereby driving the filter cartridge 23 to rotate. The rotation of the filter cartridge 23 can drive the ash scraping plate 211 to stir the outer wall of the filter cartridge 23, so that the dust adsorbed on the outer wall of the filter cartridge 23 falls off. The dust falling in the filter housing 21 falls into the filter plate 24 through the through hole 114 and enters the mixing tank 1 after being filtered by the filter plate 24. Part of the dust entering the mixing tank 1 falls on the driven gear 231. The rotation of the stirring shaft 51 can also drive the fan blade 53 to rotate. The rotation of the fan blade 53 can blow air towards the driven gear 231 to blow away the dust falling on the driven gear 231 from the filter housing 21. There are also multiple louvers on the driven gear 231 to minimize the retention of raw material dust on the driven gear 231. After a feeding mechanism 3 has transported the raw materials, the top cover 11 rotates to drive the filtering mechanism 2 to dock with the next feeding mechanism 3 that needs to transport the raw materials. The upper cover 311 and the lower cover 321 of the feeding mechanism 3 that has completed the raw material transportation are reset to prevent the leakage of raw materials and the generation of dust. Then, the feeding mechanism 3 that needs to transport the raw materials can repeat the above process to transport the raw materials in the feeding mechanism 3 into the mixing tank 1 without generating dust. Finally, after the raw materials are added and the raw materials are mixed, the subsequent processes can be carried out until the finished product packaging is completed.

[0038] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
