Description

Technical Field

[0001] The invention relates to the technical field of fertilizer processing, and in particular to energy-saving grinding equipment and a process for processing fertilizer raw materials. Background Art

[0002] Fertilizer refers to a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. It is one of the material bases of agricultural production. It mainly includes ammonium phosphate fertilizers, large-element water-soluble fertilizers, medium-element fertilizers, biological fertilizers, organic fertilizers, multi-dimensional field energy concentrated organic fertilizers, etc. In the fertilizer production process, raw materials or semi-finished products often need to be crushed to adjust their particle size and promote the uniform distribution and release of fertilizer nutrients.

[0003] At present, in the process of producing fertilizers, the fertilizer raw materials need to be ground into powder. For example, in the production of phosphate fertilizers, egg shells, bones, fish scales and other materials need to be washed, dried, crushed into small pieces and then ground into powder. These powders, as high-phosphorus fertilizers, can be gradually decomposed and released in the soil to provide necessary nutrients for plants. The existing grinding method mostly places the raw materials between two grinding discs and grinds the raw materials by rotating the grinding discs. In this grinding method, when the feed amount is small, the resistance of the grinding disc is reduced, which will cause the rotation speed of the grinding disc to suddenly increase, resulting in a certain amount of kinetic energy waste. At the same time, when the existing grinding equipment adjusts the grinding coarseness, it is necessary to remove multiple screws and adjust the distance between the two grinding discs. The operation steps are relatively cumbersome and there are certain inconveniences in use. Summary of the invention

[0004] To this end, the present invention provides an energy-saving grinding device and process for fertilizer raw material processing to solve the problem of complicated operation steps in the prior art for adjusting the distance between two grinding discs.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] Furthermore, the adjustment mechanism includes a second grinding disc, the top of the second grinding disc is threadedly connected to a screw rod, the upper end of the screw rod is rotatably connected to the inside of the bin body, and the top of the screw rod is fixedly connected to a third gear.

[0009] Furthermore, the surface of the third gear is meshed with a first gear ring, the surface of the first gear ring is fixedly connected with a meshing ring, the surface of the meshing ring is rotatably connected with a limit ring, and the bottom of the limit ring is fixedly connected to the top of the warehouse body.

[0010] Furthermore, a second gear ring is fixedly connected to the top of the first gear ring, and a fourth gear is meshed on the surface of the second gear ring.

[0011] Furthermore, a second motor is fixedly connected to the bottom of the fourth gear, and a surface of the second motor is fixedly connected to a surface of the warehouse body.

[0012] Furthermore, the screening mechanism comprises a mounting ring, the surface of the mounting ring is fixedly connected to the inner wall of the bin body, the top of the mounting ring is fixedly connected to a spring, and the top of the spring is fixedly connected to the screening groove.

[0013] Furthermore, a vibration generator is fixedly connected to the surface of the screening tank, and one side of the inner cavity of the screening tank is connected to the second discharge port through a flexible pipe.

[0014] Further, the following steps are included:

[0015] S1: placing the raw material into the feeding port, allowing the raw material to enter between the first grinding disc and the second grinding disc along the feeding port, and under the action of the first motor, driving the first grinding disc to rotate to grind the raw material, and the ground raw material enters the screening slot under the action of the gathering plate;

[0016] S2: Under the action of the vibration generator, the screening slot generates high-frequency vibration to screen the internal raw materials. Small particles of raw materials fall through the screening slot to the surface of the conical plate. During the rotation of the conical plate, they slide along the conical slope to the first discharge port for discharge;

[0017] S3: Large particle raw materials are discharged from the second discharge port along the flexible pipe, and small particle raw materials are separated from large particle raw materials.

[0020] The present invention has the following advantages: through the setting of the grinding mechanism, in the process of grinding the fertilizer raw material, the first motor drives the first grinding disk to rotate, and grinds the raw material between the two grinding disks. When the feed amount is reduced and the rotation speed of the grinding disk increases, the first motor shaft drives the second gear to rotate through the first gear, so that the generator shaft rotates quickly to generate electricity. By storing the electricity generated by the generator through the battery, the excess output kinetic energy of the first motor can be recovered, making the grinding equipment more energy-efficient. At the same time, the setting of the adjustment mechanism can drive the first gear ring to rotate through the second motor, so that multiple third gears can be driven to rotate synchronously, and then the position of the second grinding disk is adjusted through the rotation of the screw, so as to adjust the grinding coarseness, making the grinding coarseness adjustment of the grinding equipment more convenient.
