Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer screening technology, specifically a screening device for high-tower granulation compound fertilizer. Background Technology

[0002] High-tower granulation compound fertilizer is a type of granular compound fertilizer produced through a high-tower melt spraying granulation process. Its core principle is to melt nutrients such as nitrogen, phosphorus, and potassium in a scientific ratio at high temperature, and then spray them down from the top of a high tower through nozzles. During the cooling process, it forms uniform spherical particles. This process is similar to "rain forming beads". The molten fertilizer slurry naturally forms under the combined action of gravity and air resistance, without the need to add additional binders.

[0003] Publication number CN220346535U discloses a screening device for high-tower granulation compound fertilizer production. The device guides the feed into the hopper through a return cylinder, repeatedly screening the mixed small particles to fully separate the compound fertilizer granules and improve production quality. However, this patent still has the following problems in actual use:

[0004] When screening compound fertilizer, the material is screened directly through an inclined screening screen. However, during storage or transportation, compound fertilizer is prone to clumping due to external factors. The clumped compound fertilizer cannot be broken up, causing it to remain inside the device and thus affecting the screening of the material.

[0005] A screening device for high-tower granulation compound fertilizer is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a screening device for high-tower granulation compound fertilizer, in order to solve the problem mentioned in the background art that currently, when screening compound fertilizer, the material is directly screened by an inclined screening screen. However, during storage or transportation, compound fertilizer is prone to clumping due to external factors, and the clumped compound fertilizer cannot be broken up. As a result, the clumped fertilizer remains inside the device, thus affecting the screening of the material.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a screening device for high-tower granulation compound fertilizer, comprising a device body and a door installed on the front of the device body;

[0008] The device body has a feed inlet on the top and a discharge outlet on one side.

[0009] Also includes:

[0010] The device body is equipped with a screening component inside. The screening component includes a mounting plate, and a slider is symmetrically fixed on one side of the mounting plate. The slider slides inside one side of the device body. A connecting plate is fixedly connected to one side of the mounting plate, and a motor is installed on the reverse side of the connecting plate.

[0011] Among them, a disc is rotatably connected to the front of the connecting plate, and the output end of the motor is fixedly connected to the disc. A first spring is symmetrically fixed to one side of the mounting plate, and a screening shell is fixedly connected to one side of the first spring.

[0012] The screen shell is fixedly connected to the mounting plate by a telescopic rod, the screen shells are fixedly connected to each other by a fixing plate, and the top of the disc is fixedly connected to a toothed block.

[0013] Preferably, a mounting block is fixedly connected to one side of the fixing plate, and a rack is fixedly connected to the bottom of the mounting block, and the rack and the rack are engaged.

[0014] Preferably, a guide plate is fixedly connected to the bottom of the upper screening shell, and abutments are symmetrically fixed on one side of the inside of the device body.

[0015] Preferably, the abutment block abuts against the screening shell.

[0016] Preferably, the bottom of the device body is provided with a limiting component, the limiting component includes a fixed shell, two fixed shells are fixedly connected to the device body and are symmetrically arranged, a second spring is fixedly connected inside the fixed shell, a sliding rod is fixedly connected to one side of the second spring, and the sliding rod is slidably connected to the fixed shell and passes through one side of the fixed shell.

[0017] Preferably, a movable plate is fixedly connected to one side of the slide rod, and a pull handle is fixedly connected to one side of the movable plate. Furthermore, a locking block is symmetrically fixed to one side of the movable plate, and the locking block engages with the slider.

[0018] Preferably, the handle is U-shaped.

[0019] Compared with the prior art, the beneficial effects of this utility model are: this screening device for high-tower granulation compound fertilizer facilitates the shaking and screening of clumped compound fertilizer, thereby avoiding the impact of clumped compound fertilizer on the screening work. The specific details are as follows:

[0020] 1. Place the compound fertilizer to be screened into the feed inlet. The fertilizer will then enter the screening shell for screening. Simultaneously, start the motor to rotate the disc. The rotation of the disc will cause the toothed blocks to move the rack, which in turn moves the mounting block. The mounting block then moves the fixing plate, which in turn moves the two screening shells away from the abutment block. The movement of the screening shells will compress the first spring. When the toothed blocks reach a certain position, they will disengage from the rack, and the first spring will rebound, causing the screening shells to reset. The screening shells will then press against the abutment block due to the rebound of the first spring, thus breaking up any clumps of fertilizer. This achieves the purpose of shaking and screening the clumps of fertilizer. When the disc rotates to a certain extent, the toothed blocks and rack will re-engage, continuously causing the screening shells to vibrate. The screened compound fertilizer will be discharged from the outlet and collected in a collection container. After screening, the box door can be opened to check for any remaining clumps of fertilizer inside the screening shells. If any are found, they can be manually removed and disposed of.

[0021] 2. When it is necessary to disassemble, repair or replace the screening component, the handle can be pulled to move the moving plate and drive the slide rod to stretch the second spring. At the same time, the moving plate will also cause the locking block to disengage from the slider, thereby releasing the restriction on the slider. Then, the mounting plate can be slid forward and then disengage from the inside of the device body, thus making it easy to repair or replace the screening component. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 The present invention provides the following technical solution:

[0031] A screening device for high-tower granulation compound fertilizer includes a device body 1 and a door 2 installed on the front of the device body 1; a feed inlet 101 is installed on the top of the device body 1, and a discharge outlet 102 is opened on one side of the device body 1; a screening assembly 3 is provided inside the device body 1, the screening assembly 3 includes a mounting plate 301, and sliders 302 are symmetrically fixed on one side of the mounting plate 301, and the sliders 302 slide inside one side of the device body 1, and a connecting rod is fixedly connected to one side of the mounting plate 301. A connecting plate 303 is provided, and a motor 304 is mounted on the reverse side of the connecting plate 303. A disc 305 is rotatably connected to the front of the connecting plate 303, and the output end of the motor 304 is fixedly connected to the disc 305. A first spring 306 is symmetrically fixed to one side of the mounting plate 301, and a screening shell 307 is fixedly connected to one side of the first spring 306. A telescopic rod 308 is fixedly connected between the screening shell 307 and the mounting plate 301, and a fixing plate 309 is fixedly connected between the screening shells 307. Figure 2 , 3 As shown in Figure 5, the compound fertilizer to be screened is put into the feed inlet 101, and then the compound fertilizer will enter the screening shell 307 for screening. At the same time, the motor 304 is started, causing the disc 305 to rotate. The rotation of the disc 305 will cause the toothed block 310 to drive the rack 312 to move, and the toothed block 310 is fixedly connected to the top of the disc 305.

[0032] A mounting block 311 is fixedly connected to one side of the fixing plate 309, and a rack 312 is fixedly connected to the bottom of the mounting block 311. The rack 310 meshes with the rack 312. A guide plate 313 is fixedly connected to the bottom of the upper screening shell 307. Figure 2 , 5 As shown, the rack 312 drives the mounting block 311 to move, then the mounting block 311 drives the fixing plate 309 to move, and then the fixing plate 309 drives the two screening shells 307 to move away from the abutment block 314. At the same time, the movement of the screening shells 307 compresses the first spring 306. When the rack 310 moves to the moving position, it disengages from the rack 312, and the first spring 306 rebounds, thereby driving the screening shells 307 to reset. Then, the screening shells 307 will abut against the abutment block 314 through the rebound of the first spring 306. When the screening shells 307 abut against the abutment block 314, they will generate strong vibrations due to the obstruction of the abutment block 314, which can shake apart the clumped fertilizer, thereby achieving the purpose of shaking apart and screening the clumped fertilizer. When the disc 305 rotates to a certain extent, it will re-engage the rack 310 with the rack 312, thereby continuously causing the screening shells 307 to vibrate.

[0033] The sieved compound fertilizer will be discharged from the outlet 102, and a collection container structure can be used. After sieving, the box door 2 can be opened to check whether there is any residual clump fertilizer inside the screening shell 307. If so, it can be manually removed and processed. Abutment 314 is symmetrically fixed on one side of the inside of the device body 1, and abutment 314 abuts against screening shell 307.

[0034] The bottom of the device body 1 is provided with a limiting component 4. The limiting component 4 includes a fixed shell 401. Two fixed shells 401 are fixedly connected to the device body 1 and are symmetrically arranged. A second spring 402 is fixedly connected inside the fixed shell 401. A sliding rod 403 is fixedly connected to one side of the second spring 402. The sliding rod 403 is slidably connected to the fixed shell 401 and passes through one side of the fixed shell 401. A movable plate 404 is fixedly connected to one side of the sliding rod 403. Figure 2 , 6 As shown, when the screening component 3 needs to be disassembled for maintenance or replacement, the handle 405 can be pulled, causing the moving plate 404 to move and drive the slide rod 403 to stretch the second spring 402. At the same time, the moving plate 404 will also cause the locking block 406 to disengage from the slider 302, thereby releasing the restriction on the slider 302. Then, the mounting plate 301 will slide forward and then the mounting plate 301 will disengage from the inside of the device body 1, thereby making it convenient to maintain or replace the screening component 3. The handle 405 is fixedly connected to one side of the moving plate 404, and the locking block 406 is symmetrically fixed to one side of the moving plate 404. The locking block 406 is engaged with the slider 302. The handle 405 is U-shaped.

[0035] Working principle: Before using this screening device for high-tower granulation compound fertilizer, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6 As shown, firstly, when it is necessary to screen compound fertilizer, the compound fertilizer to be screened is put into the feed inlet 101, and then the compound fertilizer will enter the screening shell 307 for screening. At the same time, the motor 304 is started, causing the disc 305 to rotate. The rotation of the disc 305 will cause the toothed block 310 to drive the rack 312 to move. Then the rack 312 will drive the mounting block 311 to move. Then the mounting block 311 will drive the fixing plate 309 to move. Then the fixing plate 309 will drive the two screening shells 307 to move away from the abutment block 314. At the same time, the movement of the screening shells 307 will compress the first spring 306. When the toothed block 310 moves to the moving position, it will disengage from the rack 312, and the first spring 306 will rebound, thereby driving the screening shells 307 to return to their original position. Then, the screening shell 307 will press against the abutment block 314 due to the rebound of the first spring 306. When the screening shell 307 presses against the abutment block 314, it will generate strong vibration due to the obstruction of the abutment block 314, which can shake apart the clumps of fertilizer, thereby achieving the purpose of shaking apart and screening the clumps of fertilizer. When the disc 305 rotates to a certain extent, it will re-engage the toothed block 310 with the toothed rack 312, thereby continuously causing the screening shell 307 to vibrate. The screened compound fertilizer will be discharged from the discharge port 102, and then it can be collected in a collection container. After screening, the box door 2 can be opened to check whether there is any residual clumps of fertilizer inside the screening shell 307. If so, it can be manually removed and processed.

[0036] When the screening component 3 needs to be disassembled for inspection or replacement, the handle 405 can be pulled, causing the moving plate 404 to move and drive the slide bar 403 to stretch the second spring 402. At the same time, the moving plate 404 will also cause the locking block 406 to disengage from the slider 302, thereby releasing the restriction on the slider 302. Then, the mounting plate 301 will slide forward and then the mounting plate 301 will disengage from the inside of the device body 1, thereby making it convenient to inspect or replace the screening component 3.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
