[0027] See also Figure 1-Figure 5 The utility model provides a technical solution: a disc granulator, comprising a fixed disc frame 1, a rotating disc body 2, an electric telescopic cylinder mechanism 3 and an automatic dust-proof disc cover 4, wherein the rotating disc body 2 is rotatably installed inside the fixed disc frame 1, and the front side surface of the fixed disc frame 1 is movably installed with an automatic dust-proof disc cover 4 adapted to the rotating disc body 2 through a plurality of groups of electric telescopic cylinder mechanisms 3 arranged in an annular shape, a dust suction pipeline 41 is penetrated and installed near the top of one end surface of the automatic dust-proof disc cover 4 away from the rotating disc body 2, a water tank 42 with a pump is fixedly installed at the center of one end surface of the automatic dust-proof disc cover 4 away from the rotating disc body 2, a scraper spray mechanism 43 is arranged inside the automatic dust-proof disc cover 4 near the rotating disc body 2, and the scraper spray mechanism 43 is composed of a scraper assembly 431 and a spray assembly 432.

[0028] Among them, a filter device 411 is installed through the end of the dust suction pipeline 41 away from the automatic dustproof disc cover 4, and a suction fan 412 is installed through the side of the filter device 411 away from the dust suction pipeline 41; a feed pipeline 44 is installed through the end surface of the automatic dustproof disc cover 4 away from the rotating disc body 2 near the bottom end, and a mounting connection seat 45 is fixedly installed around the outer surface of the automatic dustproof disc cover 4 near the electric telescopic cylinder mechanism 3; a driving mechanism 1 acting on the rotating disc body 2 is fixedly installed on the back of the fixed disc frame 1 1. A base 12 is fixedly installed at the bottom of the fixed disc frame 1, and the fixed disc frame 1 and the base 12 are set at an acute angle. A reinforcement frame 13 is fixedly installed between the fixed disc frame 1 and the base 12. During production, the electric telescopic cylinder mechanism 3 works, and the automatic dust cover 4 shrinks toward the direction close to the rotating disc body 2 under the action of the electric telescopic cylinder mechanism 3, and the rotating disc body 2 is closed. The fertilizer production raw materials will be introduced into the inside of the feeding pipeline 44 to complete the feeding, and the suction fan 412 works to The dust-containing air is sucked out through the dust suction pipeline 41, filtered by the filter device 411, and then discharged. At the same time, the spray component 432 moistens the material to form a thin water film on its surface. This step provides the necessary wetting conditions for the subsequent granulation process. Then the driving mechanism 11 works. Under the action of the driving mechanism 11, the rotating disc body 2 rotates continuously. During the rotation of the disc, due to the surface tension of water, the material particles combine with each other to form small spherical cores. These spherical cores continue to absorb more materials during the rolling of the disc, gradually increase in size and form larger particles. As the disc continues to rotate, the particles roll to the edge of the disc under the action of centrifugal force. Then, under the action of the electric telescopic cylinder mechanism 3, the dust disc cover 4 is automatically unfolded, so that the particles are discharged at the edge. During the entire operation, the dust can be effectively prevented from flying during the operation of the disc granulator to avoid damage to the eyes, respiratory tract, etc. of the operator. It has the functions of dust suction, filtration and discharge, and the operation is automated, which is more efficient and convenient.

[0029] In addition, in this embodiment, please refer to Figure 3 and Figure 4 The scraper assembly 431 includes a center seat 4311 fixedly installed at the center of the automatic dustproof disc cover 4, an eccentric seat 4312 fixedly installed on one side of the center seat 4311, a knife holder 4314 movably installed between the center seat 4311 and the eccentric seat 4312 through a sliding sleeve 4313, and a scraper body 4315 fixedly installed on the side of the knife holder 4314 close to the rotating disc body 2. The scraper body 4315 can scrape the forming ring from the inner layer of the forming ring to the outside, and remove the particles that are not suitable for shrinkage or do not meet the requirements, so that the shape of the particles is more neat and the rigor is higher. At the same time, the consistency of the particle size can be ensured, making the granulation process more stable;

[0030] In addition, in this embodiment, please refer to Figure 3and Figure 4 The outer surfaces of the center seat 4311 and the eccentric seat 4312 are provided with a plurality of groups of adjusting grooves 4316 distributed in an annular shape. Adjusting sliders corresponding to the plurality of groups of adjusting grooves 4316 distributed in an annular shape are fixedly installed around the inner wall of the sliding sleeve 4313, and the adjusting sliders are slidably connected with the adjusting grooves 4316. The outer surface of the sliding sleeve 4313 is spirally installed with locking bolts 4317. The position of the scraper body 4315 can be mechanically adjusted by the arranged adjusting grooves 4316, adjusting sliders and locking bolts 4317, so that particles of different diameters can be produced.

[0031] In addition, in this embodiment, please refer to Figure 3 and Figure 5 The spray assembly 432 includes a delivery pipeline 4321 installed through the center seat 4311, and a plurality of groups of atomizing nozzles 4322 are fixedly installed on one side of the delivery pipeline 4321 close to the rotating disc body 2.

The visible liquid level sensor 422, and the pump water tank 42 and the delivery pipeline 4321 are connected through. When wetting the material, the pump water tank 42 works to deliver the raw water to the atomizing nozzle 4322 through the delivery pipeline 4321, and the atomizing nozzle 4322 sprays the material to wet it, and stops working after reaching a certain degree of wetness. The digital liquid level sensor 422 can be set to facilitate the staff to check the water level of the pump water tank 42, and to facilitate timely replenishment of water inside it through the raw water pipeline 421;

[0032] The working process of the utility model is as follows: during production, the electric telescopic cylinder mechanism 3 works, and under the action of the electric telescopic cylinder mechanism 3, the automatic dustproof disc cover 4 shrinks toward the direction close to the rotating disc body 2, and closes the rotating disc body 2, and the fertilizer production raw materials are introduced into the inside of the feeding pipeline 44 to complete the feeding, and the suction fan 412 works to suck out the dust-containing air through the dust suction pipeline 41, and uses the filter device 411 to filter it, and then discharges it. At the same time, the spray component 432 wets the material to form a thin water film on its surface. This step provides the necessary wetting conditions for the subsequent granulation process. When wetting the material, the pump water tank 42 works to pass the raw water through the delivery pipe The material is transported to the atomizing nozzle 4322 through the path 4321, and the atomizing nozzle 4322 sprays and moistens the material. The operation stops when a certain degree of wetness is reached, and then the driving mechanism 11 works. Under the action of the driving mechanism 11, the rotating disc body 2 rotates continuously. During the rotation of the disc, due to the surface tension of water, the material particles combine with each other to form small spherical cores. These spherical cores continue to absorb more material during the rolling of the disc, gradually increase in size and form larger particles. As the disc continues to rotate, the particles roll to the edge of the disc under the action of centrifugal force, and then the dustproof disc cover 4 is automatically unfolded under the action of the electric telescopic cylinder mechanism 3, so that the particles are discharged at the edge.
