Description

Technical Field

[0001] The utility model belongs to the technical field of fertilizer production, in particular to a raw material elevator for high-tower compound fertilizer production. Background Art

[0002] High-tower compound fertilizer is a granulation method for urea and potash fertilizer melts. It utilizes the principle of rapid crystallization after urea is melted. The ammonium phosphate is heated and metered with urine and potassium slurries, and then sprayed into a high-tower through a nozzle to produce compound fertilizer granules. This fertilizer has the characteristics of uniform and smooth granules, melting holes, and no agglomeration. Its appearance, internal quality, and effect on crop yield are far superior to ordinary compound fertilizers sold on the market. However, during the production and processing of high-tower compound fertilizers, it is often necessary to use a hoist to lift a large amount of raw materials to a high altitude for easy docking with the processing equipment to ensure the production and processing efficiency of the high-tower compound fertilizer. However, in actual use, it still has the following disadvantages:

[0003] 1. The utility model with publication number CN216302323U discloses a fertilizer production elevator. The top wall and the bottom wall of the elevator box are both provided with material removers. The material removers are used to remove adhering fertilizers. This utility model can avoid material blockage in the elevator and avoid affecting production efficiency. However, in actual production, the discharge port and feed port of the elevator are often located on both sides of the elevator, so that the elevator hopper needs to be moved to the highest point of the elevator and turned over before the material can be discharged. This prolongs the time required for the material to be lifted in the elevator and increases the load burden of the elevator. In addition, the elevator hopper is prone to spilling a small amount of material during the turning process, which reduces the conveying efficiency.

[0004] 2. When the elevator is in production and processing, it is often necessary to weld the position of the discharge port according to customer needs. However, in actual production, since there are often multiple production and processing devices to process different materials simultaneously, in order to improve the processing efficiency of the materials, it is necessary to set up multiple elevators to lift the materials, which not only takes up a lot of space in the production workshop, but also greatly increases the production cost. Utility Model Content

[0005] The purpose of the utility model is to provide a raw material elevator for the production of high-tower compound fertilizers. Through the elevator body, the discharge limit rod and the lifting hopper, the problem that when the raw material elevator is actually used, the material often needs to be lifted to the highest point by the lifting device and turned over before it can be discharged, which prolongs the time required for the material to be lifted in the elevator, increases the load-bearing burden of the lifting device, and the lifting hopper is prone to cause a small amount of material to be spilled during the turning process. When multiple production and processing devices process multiple materials, multiple elevators need to be used, which reduces space utilization and increases production costs.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a raw material elevator for high-tower compound fertilizer production, comprising an elevator body, a discharge limiting rod and an elevator hopper, wherein discharge ports are penetrated on both sides of the elevator body, a conveyor belt is rotatably connected in the center of the elevator body, a discharge limiting rod is slidably connected in each of the discharge ports, a discharge limiting belt is fixedly connected to one side of the bottom of each of the discharge limiting rods, a plurality of elevator hoppers are attached to the outer circumference of the conveyor belt, the elevator hoppers are attached to the two discharge limiting rods and the inner side of the discharge limiting belt, and a magnetic guide plate is rotatably connected to the bottom of each of the elevator hoppers;

[0008] The discharge ports on both sides of the elevator can enable fertilizer raw materials to be discharged from high positions on both sides of the elevator as needed, thereby improving the flexibility of the elevator. In the process of lifting the raw materials upward, the raw materials that have been lifted to an appropriate height can be discharged, thereby reducing the time the raw materials are in the elevator, reducing the load of the elevator per unit time, and extending the service life of the elevator. The rotation of the conveyor belt can drive the lifting hopper to move to a high place, which is convenient for conveying a large amount of raw materials. The staff can also adjust the height of the discharge limit rod and the length of the discharge limit belt according to the position and height of the production and processing equipment, so that the material can be discharged after moving to an appropriate height, so that the elevator can discharge at different positions, and one elevator can be used in conjunction with multiple production and processing equipment, thereby reducing production costs and improving space utilization. The magnetic guide plate can be adsorbed and rotated according to the discharge position, diverting the material poured into the lifting hopper, so that the material moved to the specified height can be discharged quickly.

[0009] Furthermore, a feed pipe is welded through the bottom of one side of the elevator body, a feed hopper is welded through the top of the outer peripheral surface of the feed pipe, one end of the feed pipe is clamped with a feeding motor, one end of the feeding motor is clamped with a driving rod, a spiral feeding assembly is welded and fixed to the outer peripheral surface of the driving rod, the driving rod is inserted through one end of the feed pipe, the spiral feeding assembly is located on the inner side of the feed pipe, and a slide groove is provided on one side of each of the discharge ports;

[0010] The feeding motor drives the spiral feeding assembly to rotate, which can further drive the raw materials poured into the feed hopper to quickly enter the lifting hopper, ensuring the feeding speed of the material. The discharge ports on both sides of the elevator can enable the fertilizer raw materials to be discharged from high places on both sides of the elevator as needed, thereby improving the flexibility of the elevator. In the process of lifting the raw materials upward, the raw materials that have been lifted to an appropriate height can be discharged, reducing the time the raw materials stay in the elevator, reducing the load of the elevator per unit time, and extending the service life of the elevator.

[0011] Furthermore, a lifting motor is connected through one side of the lifting machine body, a rotating roller is connected in rotation in the lifting machine body, one rotating roller is connected to one end of the lifting motor, and the conveyor belt is attached to the outer circumference of the rotating roller;

[0012] The lifting motor can drive the rotation of the rotating roller, which further drives the rotation of the conveyor belt, so that multiple lifting hoppers move with the transmission belt, lifting a large amount of raw materials and improving the automation level of the elevator.

[0013] Furthermore, an automatic winding assembly is clamped at the bottom of each of the discharging limiting belts, and the automatic winding assembly is clamped on the inner side of the elevator body. A slider is clamped at one end of each of the discharging limiting rods, a threaded tube is clamped through the top of the slider, a threaded rod is screwed through the top of the threaded tube, and a stepping motor is clamped at the bottom of the threaded rod. The two sliders are respectively slidably clamped on the inner sides of the two chutes, and the threaded rod and the stepping motor are both clamped on the inner sides of the chutes.

[0014] The automatic winding component can wind up the discharge limit belt to ensure sufficient tension of the discharge limit belt. The stepper motor drives the rotation of the threaded rod, which can further drive the slider and the discharge limit rod to move up and down. The discharge limit belt is reeled and unreeled by the automatic winding component, so that the lifting hopper can only discharge when the top is higher than the discharge limit rod. The hoist can adjust the discharge position according to the height and position of the production and processing equipment, thereby improving the flexibility of the hoist and enabling one hoist to be used in conjunction with multiple production and processing equipment, reducing production costs and improving space utilization.

[0015] Furthermore, a clamping block is welded and fixed on one side of each of the lifting hoppers, electromagnets are clamped at both ends of the inner bottom of each of the lifting hoppers, a rotating shaft is clamped and fixed at the center of the bottom of each of the magnetic guide plates, and barrier strips are clamped at both ends of the bottom of each of the magnetic guide plates. The clamping block is clamped on the outer circumference of the conveyor belt, and the rotating shaft is rotatably clamped in the center of the inner bottom of the lifting hopper. The other end of the barrier strip relative to the magnetic guide plate is clamped on the inner bottom of the lifting hopper.

[0016] According to the discharge position, the electromagnet in the corresponding direction is turned on to adsorb one end of the magnetic guide plate, so that the adsorbed end of the magnetic guide plate rotates downward. When the lifting hopper moves to the discharge position, the raw materials in the lifting hopper can be quickly discharged along the inclined direction of the magnetic guide plate under the action of gravity.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model solves the problem that the discharge port and feed port of the elevator are often located on both sides of the elevator by arranging an elevator body and a lifting hopper, so that the lifting hopper needs to be moved to the highest point of the lifting device and turned over before the material can be discharged, which prolongs the time required for the material to be lifted in the elevator, increases the load-bearing burden of the lifting device, and easily causes a small amount of material to be spilled during the turning process of the lifting hopper, thereby reducing the conveying efficiency. When the rotation of the conveyor belt drives the lifting hopper to lift, when the lifting hopper moves to an appropriate height, the raw materials can be discharged along the magnetic guide plate and through the discharge port under the action of gravity. The discharge ports on both sides of the elevator body can enable the raw materials that have been lifted to an appropriate height to be discharged during the upward lifting process, thereby reducing the time the raw materials are in the elevator, reducing the load of the elevator per unit time, and extending the service life of the elevator.

[0019] 2. The utility model solves the problem that the position of the discharge port of the elevator often needs to be welded according to customer needs during production and processing by setting the elevator body and the discharge limit rod. However, in actual production, since there are often multiple production and processing devices to process different materials synchronously, in order to improve the processing efficiency of the materials, it is necessary to set up multiple elevators to lift the materials, which not only takes up a large amount of space in the production workshop, but also greatly increases the production cost. The staff can control the stepper motor to drive the threaded rod to rotate according to the height and position of the production and processing device being used, so that the discharge limit rod moves up and down to the corresponding height, and at the same time rewinds and unwinds the discharge limit belt. When the lifting hopper moves upward, the raw material is limited by the discharge limit belt, so that the lifting hopper can only discharge after reaching the specified height, thereby improving the flexibility of the elevator. And one elevator can be used in conjunction with multiple production and processing devices, reducing production costs and improving space utilization. BRIEF DESCRIPTION OF THE DRAWINGS

According to the position of the feed port of the production and processing device, the electromagnets 305 in the corresponding directions of the multiple lifting hoppers 3 are controlled to open, so that the corresponding end of the magnetic guide plate 302 rotates downward and fits the bottom of the lifting hopper 3, pouring a large amount of fertilizer raw materials into the feed hopper 108, and the spiral feeding assembly 110 is driven to rotate by the feeding motor 103, so that the material quickly passes through the feed pipe 101 and enters the lifting hopper 3, and the conveyor belt 104 is driven to rotate by the lifting motor 102, so that multiple lifting hoppers 3 move with the conveyor belt 104, lifting a large amount of raw materials. When the top of the lifting hopper 3 moves to above the discharge limit rod 2, the material is discharged through the discharge port 106 under the action of gravity.

A rotating roller 105 is clamped at one end of the lifting motor 102, and a conveyor belt 104 is attached to the outer circumference of the rotating roller 105.

[0031] A large amount of raw materials are poured into the feed hopper 108, and the raw materials fall into the feed pipe 101 under the action of gravity. The feed motor 103 drives the drive rod 109 and the spiral feed assembly 110 to rotate, further driving the large raw materials through the feed pipe 101 into the lifting hopper 3, and the lifting motor 102 drives the rotating roller 105 to rotate, further driving multiple lifting hoppers 3 to move with the rotation of the conveyor belt 104, so that the lifting hopper 3 is lifted to the corresponding height and then discharged.

One end of each discharging limiting rod 2 is clamped with a slider 203, and the top of the slider 203 is clamped with a threaded tube 206, and the top of the threaded tube 206 is screwed with a threaded rod 205, and the bottom of the threaded rod 205 is clamped with a stepping motor 204. The two sliders 203 are respectively slidably clamped on the inner sides of the two chutes 107, and the threaded rod 205 and the stepping motor 204 are both clamped on the inner sides of the chutes 107.

[0033] According to the height of the feed port of the production and processing device, the stepper motor 204 is controlled to drive the threaded rod 205 to rotate, and further drive the discharge limit rod 2 to slide along the slide groove 107 to an appropriate height. At the same time, the automatic winding component 202 rewinds and unwinds the discharge limit belt 201, so that when the lifting hopper 3 is lifted, the discharge limit belt 201 can limit the raw materials in the lifting hopper 3.

[0034] Among them Figure 1 、 2As shown in Figure 5, a clamping block 301 is welded and fixed on one side of each lifting hopper 3, and electromagnets 305 are clamped at both ends of the bottom of each lifting hopper 3. A rotating shaft 303 is clamped and fixed at the center of the bottom of each magnetic guide plate 302, and a barrier belt 304 is clamped at both ends of the bottom of each magnetic guide plate 302.
