Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production, in particular to a fertilizer drying device for fertilizer production. Background Art

[0002] A drying device is a device used to remove moisture or other volatile components from materials. Its purpose is to create suitable conditions through various physical, chemical or mechanical methods to evaporate the moisture or solvent in the material, thereby achieving the effect of reducing the moisture content of the material or removing specific components.

[0003] Existing drying methods mostly involve stirring materials, turning the materials over, and using internal heat to remove moisture. During the stirring process, collisions and friction may occur between material particles and between the materials and the stirring components, causing the material particles to break. Stirring and drying can cause uneven stirring, resulting in some materials being over-dried and others being under-dried. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a fertilizer drying device for fertilizer production to solve the problem of material damage and insufficient drying.

[0005] Based on the above purpose, the utility model provides a fertilizer drying device for fertilizer production, including: a drying device body, an auger feed pipe is arranged inside the drying device body, a spiral auger is rotatably connected inside the auger feed pipe, the spiral auger is fixedly installed on a drive shaft, a rotating bearing is fixedly connected to the lower end of the drive shaft, the rotating bearing is fixedly connected to the bottom end of the turbine disc body, the turbine disc body is rotatably connected to the outside of the auger feed pipe and fits with the outside of the auger feed pipe, and a fertilizer unfolding disc is fixedly connected to the end of the auger feed pipe away from the turbine disc body.

[0006] As an optional embodiment, the end of the drive shaft away from the rotating bearing is fixedly connected to a first servo motor, the first servo motor passes through the drying device body and is fixedly mounted on a support base, and the support base is fixedly mounted on the outside of the drying device body.

[0007] As an optional embodiment, a conical material gathering piece is provided on the outer side of the turbine disc body, and the conical material gathering piece is fixedly installed on the end of the drying device body away from the first servo motor. A plurality of evenly distributed material gathering turbine teeth are fixedly installed inside the turbine disc body, and a second servo motor is fixedly connected to the bottom end of the turbine disc body, and the second servo motor is fixedly installed on the support seat.

[0008] As an optional implementation, a discharge pipe is slidably connected to the groove on the conical material gathering piece, and a discharge hole is provided inside the discharge pipe.

[0009] As an optional implementation, one end of the discharge pipe away from the conical gathering piece is fixedly connected to a cylinder, and the cylinder is fixedly mounted on the support seat.

[0010] As an optional implementation, a feed port is fixedly connected to the outer side of the drying device body, and a gas filter box is fixedly connected to the upper end of the drying device body on the same side as the first servo motor.

[0011] As an optional implementation, a plurality of evenly distributed electric heating plates are fixedly mounted on the inner side wall of the drying device body, and a plurality of evenly distributed heat-conducting tubes are fixedly mounted on the electric heating plates.

[0012] Beneficial effects of the utility model:

[0013] 1. The utility model adds fertilizer into the drying device body from the feed port, and the first servo motor drives the spiral auger to rotate, and pushes the fertilizer to the fertilizer unfolding plate through the auger feed pipe. As the fertilizer is continuously pushed, the fertilizer is evenly sprinkled downward along the edge of the fertilizer unfolding plate, so that it can be more fully exposed to the air, making the heat transfer more uniform, avoiding local overheating or overcooling, thereby ensuring the consistency of drying quality, and then shortening the time required for drying, improving drying efficiency, and reducing the damage caused by repeated stirring and collision between materials through scattered drying.

[0014] 2. The utility model drives the turbine disc body to rotate forwardly through the second servo motor, and transports the fertilizer upward from the bottom to dry layer by layer through the gathering turbine gear auger. The drying degree of each layer of fertilizer can be controlled more accurately to ensure that the whole reaches an ideal drying state and avoids over-drying or under-drying. When the dried fertilizer needs to be pushed out, the cylinder is started to push the discharge pipe upward, and the discharge hole is pushed to the inside of the drying device body. The second servo motor is started to reverse and the fertilizer inside the drying device body is pushed outward. The discharge rate is changed by adjusting the speed of the second servo motor.

[0025] The end of the driving shaft 103 away from the rotating bearing 107 is fixedly connected with a first servo motor 101. The first servo motor 101 penetrates the drying device body 1 and is fixedly mounted on a support base 2. The support base 2 is fixedly mounted on the outside of the drying device body 1.

[0026] A feed port 3 is fixedly connected to the outer side of the drying device body 1 , and a gas filter box 4 is fixedly connected to the upper end of the drying device body 1 on the same side as the first servo motor 101 .

[0027] In this way, when fertilizer is added into the drying device body 1 from the feed inlet 3, the first servo motor 101 drives the spiral auger 104 to rotate, and the fertilizer is pushed to the fertilizer unfolding disk 102 through the auger feed pipe 109. As the fertilizer is continuously pushed, the fertilizer is evenly sprinkled downward along the edge of the fertilizer unfolding disk 102, so that it can be more fully exposed to the air, making the heat transfer more uniform, avoiding local overheating or overcooling, thereby ensuring the consistency of drying quality, and then shortening the time required for drying, improving drying efficiency, and reducing the damage caused by repeated stirring and collision between materials through scattered drying.

[0028] As an optional implementation, Figure 1-Figure 4 As shown, a conical material gathering piece 105 is arranged outside the turbine disc body 106, and the conical material gathering piece 105 is fixedly installed at the end of the drying device body 1 away from the first servo motor 101, and a plurality of uniformly distributed material gathering turbine teeth 114 are fixedly installed inside the turbine disc body 106, and a second servo motor 108 is fixedly connected to the bottom end of the turbine disc body 106, and the second servo motor 108 is fixedly installed on the support seat 2;

[0034] In this embodiment, the interior of the drying device body 1 is heated by the electric heating plate 110, and the heat is expanded by the heat conducting pipe 111, so that the heat is more evenly distributed in the heating area, avoiding local overheating or overcooling, thereby ensuring the uniformity of heating, and being able to quickly conduct the heat generated by the heating plate, significantly improving the speed and efficiency of heat transfer. When fertilizer is added into the drying device body 1 from the feed inlet 3, the first servo motor 101 drives the spiral auger 104 to rotate, and the fertilizer is pushed to the fertilizer unfolding disk 102 through the auger feed pipe 109. As the fertilizer is continuously pushed, the fertilizer is evenly sprinkled downward along the edge of the fertilizer unfolding disk 102, and can be more fully exposed to the air, making the heat transfer more uniform, avoiding local overheating or overcooling, thereby ensuring the consistency of the drying quality, and thus shortening the time required for drying.

The second servo motor 108 drives the turbine disc body 106 to rotate forward, and the fertilizer added to the inside of the drying device body 1 is gathered to the bottom of the spiral auger 104 through the gathering turbine teeth 114, so that the spiral auger 104 can transport the fertilizer from the bottom inside layer by layer upward for drying, and can more accurately control the drying degree of each layer of fertilizer to ensure that the whole reaches the ideal drying state and avoid over-drying or insufficient drying. When the dried fertilizer needs to be pushed out, the cylinder 113 is started to push the discharge pipe 112 upward, and the discharge hole 115 is pushed to the inside of the drying device body 1, and the second servo motor 108 is started to reverse, and the fertilizer inside the drying device body 1 is pushed outward, and the discharge rate is changed by adjusting the speed of the second servo motor 108.
