Description

Technical Field

[0001] The utility model relates to the technical field of granulation devices, in particular to a granulation device for composite microbial fertilizers. Background Art

[0002] Nowadays, the use of granulation equipment is more common in industrial production. After the strips are discharged from the die, they are cooled by a blower or air, or by a water bath. If water cooling is used, the strips need to pass through a drying section, and the moisture is blown off by forced ventilation, and then the strips are sent to the pelletizing chamber.

[0003] Patent CN218554007U proposes a granulation device for a composite microbial fertilizer. The composite microbial fertilizer is squeezed through the granulator body by means of a side fixing plate and a hanging ear. The motor is started to drive the fan blades and the mounting ring to rotate. The fan blades drive the airflow to enter from the air inlet, and the air is guided through the guide hole. The air is transmitted to the equipment housing through the inclined hole, and the blade is driven to rotate through the mounting ring. The logistics is granulated by the blade. The particles are subjected to air resistance to reduce the descending speed. At the same time, the surface of the particles is air-dried. The air-dried particles are introduced into the receiving barrel through the guide tube, thereby realizing the convenient anti-adhesion treatment of the granulation equipment.

[0004] In the above scheme, the fertilizer particles are blown to remove moisture when they fall to avoid sticking. However, in this process, it is impossible to blow air evenly to each particle, and the particles are easily blocked by each other when falling, which leads to the particles far from the air outlet not being able to be dried well, affecting the quality of the particles delivered. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a granulation device for composite microbial fertilizer to solve the problems raised in the above-mentioned background technology. The utility model has a novel structure. Through the reciprocating swing of two inclined plates, the limit plate cooperates with the inclined plate to slide along the slide groove, and the particles dropped on the inclined plate are pushed back and forth, thereby increasing the time that the particles stay on the inclined plate. Moreover, since the inclined plate is constantly rotating, the adhesion of the particles can be avoided, thereby improving the effect of air-drying the particles and avoiding the problem of uneven air-drying.

[0006] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a granulation device for composite microbial fertilizer, comprising a processing box, a pelletizing box is fixed at the bottom of the processing box, and feed ports are opened on both sides of the top of the pelletizing box, a granulating plate is fixed at the connection between the pelletizing box and the processing box, air outlets are opened on the tops of both sides of the processing box, and a bellows is fixed at the bottom of the processing box, the bellows is triangular, and inclined plates with leakage grooves are rotatably installed on both sides of the bellows through a rotating shaft, and a limit plate is slidably installed on the bottom of the inclined plate, the processing box is provided with outlets on both sides of the bellows, and an electromagnetic baffle is installed on the inner wall of the processing box at the outlet.

[0007] Furthermore, a mounting cavity is provided inside the bellows, and two sides of the bellows are hollowed out, and an air inlet is provided at the bottom of the bellows.

[0008] Furthermore, gears are provided on the outer wall of the processing box at positions corresponding to the rotational installation of the two inclined plates, and the gears are fixed to the rotation shaft of the inclined plates, the two gears are meshed and connected, and a motor is fixed on the outer wall of the gear on one side of the processing box, and the output end of the motor is fixed to the gear.

[0009] Furthermore, slide grooves are provided on both sides of the inclined plate, the bottom of the limit plate slides along the slide grooves, and the limit plate is fixed to the inner wall of the slide groove by a spring.

[0010] Furthermore, a pressing plate is provided on the top of the pelletizing box, and a cylinder is fixed on the outer wall of the top of the pelletizing box, and the extended end of the cylinder is fixed to the pressing plate.

[0011] Furthermore, the processing box is fixed with bidirectional electric push rods on the inner walls on both sides of the granulation plate, and the extended ends of the bidirectional electric push rods are fixed with cutters.

[0012] Furthermore, a stopper is fixed at the middle position of the bottom of the granulating plate.

[0014] The utility model blocks the end of the inclined plate away from the limiting plate by the stopper, so as to prevent particles from falling out of the inclined plate when the inclined plate rotates to be close to horizontal.

[0015] When the inclined plate of the utility model rotates, the pressure on the limiting plate becomes smaller, so that the spring in the slide groove contracts, pushing the particles to move toward the upper end of the inclined plate, thereby increasing the fluidity of the particles.

[0016] Compared with the prior art, the utility model uses two inclined plates to swing back and forth, and the limit plate cooperates with the inclined plate to slide along the slide groove, so as to push the particles dropped on the inclined plates back and forth, thereby increasing the time the particles stay on the inclined plates, and because the inclined plates are constantly rotating, the particles can be avoided from sticking, thereby improving the effect of drying the particles and avoiding the problem of uneven drying.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4The utility model provides a technical solution: a granulation device for composite microbial fertilizer, comprising a processing box 1, a pelletizing box 2 is fixed at the bottom of the processing box 1, and feed ports 21 are opened on both sides of the top of the pelletizing box 2, a granulating plate 24 is fixed at the connection between the pelletizing box 2 and the processing box 1, air outlets 11 are opened on both sides of the top of the processing box 1, and a wind box 3 is fixed at the bottom of the processing box 1, the wind box 3 is triangular, and inclined plates 31 with leakage grooves are installed on both sides of the wind box 3 through a rotating shaft, and the inclined plates 31 A limit plate 35 is slidably installed at the bottom, and the processing box 1 is provided with outlets on both sides of the bellows 3, and an electromagnetic baffle 15 is installed on the inner wall of the processing box 1 located at the outlet. When the device is used, the composite microbial fertilizer mixed raw materials are respectively fed into the two feed ports 21, and then the pellets are pressed by the granulating plate 24 and fall on the inclined plate 31. The inclined plate 31 swings back and forth to increase the fluidity of the particles, and cooperates with the blowing of the bellows 3 to quickly dry them, and then the electromagnetic baffle 15 is opened to throw out and collect the particles exceeding the limit plate 35.

[0024] In this embodiment, the bellows 3 is provided with an installation cavity 36, and both sides of the bellows 3 are hollowed out. An air inlet 37 is provided at the bottom of the bellows 3. After the fan is installed, the particles on the inclined plate 31 are blown dry by the cooperation of the air inlet 37 and the blowing port.

[0025] The gears 33 are meshed with each other, and the motor 32 is fixed on the outer wall of the gear 33 on one side of the processing box 1, and the output end of the motor 32 is fixed to the gear 33. Slide grooves 34 are provided on both sides of the inclined plate 31, and the bottom of the limit plate 35 slides along the slide groove 34, and the limit plate 35 is fixed to the inner wall of the slide groove 34 by a spring. The motor 32 drives the gear 33 to rotate. Through the meshing of the two gears 33, the two inclined plates 31 swing synchronously in opposite directions. When the number of particles on the inclined plate 31 gradually increases, they will accumulate at one end of the limit plate 35, thereby squeezing the limit plate 35 to move downward along the slide groove 34. When the inclined plate 31 rotates, the pressure on the limit plate 35 becomes smaller, thereby the spring in the slide groove 34 contracts, pushing the particles to move to the upper end of the inclined plate 31, thereby increasing the fluidity of the particles.

[0026] In this embodiment, a pressing plate 23 is provided on the top of the pelletizing box 2, and a cylinder 22 is fixed on the outer wall of the top of the pelletizing box 2, and the extended end of the cylinder 22 is fixed to the pressing plate 23. The processing box 1 is located on the inner walls on both sides of the granulation plate 24 and fixed with a bidirectional electric push rod 13, and the extended end of the bidirectional electric push rod 13 is fixed with a cutter 14. The cylinder 22 drives the pressing plate 23 to extrude the composite microbial fertilizer raw materials in the pelletizing box 2 and send them out through the granulation plate 24, and the bidirectional electric push rod 13 drives the cutters 14 on both sides to cut the pellets.

[0027] In this embodiment, a stopper 12 is fixed at the middle position of the bottom of the granulating plate 24, and the stopper 12 blocks the end of the inclined plate 31 away from the limiting plate 35, so as to prevent the particles from falling out of the inclined plate 31 when the inclined plate 31 rotates to a near horizontal position.

[0028] When the device is used, the composite microbial fertilizer mixed raw materials are fed in from the two feed ports 21 respectively, and then the pellets are pressed by the granulating plate 24 and fall onto the inclined plate 31. The motor 32 drives the gear 33 to rotate, and the two inclined plates 31 swing synchronously in opposite directions through the meshing of the two gears 33. When the particles on the inclined plate 31 gradually increase, they will accumulate at one end of the limit plate 35, thereby squeezing the limit plate 35 to move downward along the chute 34. When the inclined plate 31 rotates, the pressure on the limit plate 35 becomes smaller, thereby the spring in the chute 34 contracts and pushes the particles to move to the upper end of the inclined plate 31, thereby increasing the fluidity of the particles, and cooperating with the blowing of the bellows 3 to quickly dry them, and then the electromagnetic baffle 15 is opened to throw out and collect the particles exceeding the limit plate 35.
