Description

Technical Field

[0001] This application relates to the technical field of fertilizer processing, and in particular to a pretreatment device for water-soluble fertilizer raw materials. Background Technology

[0002] Water-soluble fertilizer raw material pretreatment equipment is used in the production process of water-soluble fertilizer to process the initial raw materials to meet the requirements of subsequent production processes. Through operations such as crushing and pulverizing, raw materials in the form of lumps and granules are processed into appropriate particle sizes, such as crushing clumps of urea to ensure uniform mixing in the later stages.

[0003] A search revealed that Chinese patent application number CN202320842851.5 discloses a water-soluble fertilizer pretreatment device, which relates to the field of fertilizer pretreatment technology. The upper end of the reaction cylinder is fixedly installed with a cover plate, the upper surface of the cover plate is provided with a feed inlet, a baffle is fixedly installed on one side of the feed inlet, and a discharge plate is provided above the feed inlet, with the lower end of the discharge plate fixedly installed on the upper outer surface of the reaction cylinder.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: The existing technologies guide materials through a feeding plate and then crush the inner wall of the material conveyor through the feed inlet. When crushing water-soluble fertilizers, dust is generated during the cutting process. This dust splashes out from the feed inlet. If the splashed dust contains chemical components, such as nutrients like nitrogen, phosphorus, and potassium in water-soluble fertilizers, as well as other trace elements that may be added, it will affect air quality when dispersed into the air and may have adverse health effects if inhaled.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. By setting up processing components, dust removal mechanisms, and feed inlets, this utility model enables the high-pressure air pump in the dust removal mechanism to draw air from the inside of the conveying pipe during the material processing process of the processing components. The gas is drawn out from the processing box through the air guide frame and air guide groove, creating a negative pressure inside the processing box. The gas enters from the inner wall of the feed inlet, thereby guiding the dust in the processing process, suppressing the dust generated from the inner wall of the feed inlet during the crushing process, reducing environmental pollution, and optimizing the internal working environment.

[0016] 2. This utility model, by setting up locking components, baffles, and pressing mechanisms, allows the locking block to be separated from the limiting plate by operating the squeezing block to press the spring after use. This allows the telescopic block to be pressed down to release the restriction on the lower side of the hopper. After the hopper is flipped over, one end of it is separated from the upper side of the feed inlet. The feed inlet can be protected by rotating the baffle. This reduces the amount of dust entering the processing box from the inner wall of the feed inlet when not in use, thus ensuring the cleanliness of the processing box. Attached Figure Description

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1—4 provides further detailed description of this application.

[0023] This application discloses a pretreatment device for water-soluble fertilizer raw materials. For example... Figure 1 As shown, the device includes a processing box 1, with a feed inlet 2 on the upper side of the processing box 1. Two support blocks 3 are fixedly connected to the upper side of the processing box 1. A baffle 4 is rotatably fitted on the adjacent side of the two support blocks 3. Two mounting blocks 5 are fixedly connected to one side of the processing box 1. A hopper 6 is rotatably fitted on the adjacent side of the two mounting blocks 5. A pressing mechanism 7 that abuts against the baffle 4 is provided on one side of the hopper 6.

[0024] Please see Figure 3 The top pressing mechanism 7 includes two empty slot blocks 701 fixedly connected to one side of the hopper 6, an elastic block 702 slidably fitted on the inner wall of the empty slot block 701, and a compression spring 703 fixedly connected between the elastic block 702 and the empty slot block 701. When the hopper 6 is unfolded, its elastic block 702 presses against the baffle 4, so that the baffle 4 protects one end of the hopper 6 and prevents the material from rushing out of the hopper 6.

[0025] Please see Figure 1 and Figure 4 A welding ring 16 is fixedly connected to the outside of the treatment box 1, and multiple support legs 17 are fixedly connected to the lower side of the welding ring 16. The support legs 17 contact the ground, and the welding ring 16 is fixed to the treatment box 1, thereby supporting the treatment box 1.

[0026] Please see Figure 1 and Figure 3 A handle 18 is fixedly connected to one side of the hopper 6, and a stop block 19 is fixedly connected to the adjacent side of the two support blocks 3. The stop block 19 abuts against the baffle 4. The handle 18 facilitates the operation of the hopper 6, and the stop block 19 can be used to limit one side of the baffle 4.

[0027] Two mounting blocks 5 are rotatably fitted with a flipping block 8 on their adjacent sides. The inner wall of the flipping block 8 is slidably fitted with a telescopic block 9 that contacts the lower side of the hopper 6. A movable opening 10 is provided on one side of the flipping block 8. A limiting block 11 that is fixedly connected to the flipping block 8 is slidably fitted on the inner wall of the movable opening 10. A locking component 12 is provided on one side of the limiting block 11. A limiting plate 13 that cooperates with the locking component 12 is provided on one side of the flipping block 8. A processing component 14 is provided inside the processing box 1. A dust removal mechanism 15 that cooperates with the processing component 14 is provided on one side of the processing box 1.

[0028] Please see Figure 2The locking assembly 12 includes a drive groove 121 formed on one side of the limiting block 11, a pressing block 122 slidably fitted on the inner wall of the drive groove 121, a spring piece 123 fixedly connected between the pressing block 122 and the drive groove 121, and a locking block 124 fixedly connected on one side of the pressing block 122 and inserted into the limiting plate 13. The spring piece 123 presses the pressing block 122 to insert the locking block 124 into the limiting plate 13, which in turn drives the telescopic block 9 to be fixed, so that the telescopic block 9 presses against the lower side of the hopper 6 to ensure the stability of the hopper 6 when pouring material.

[0029] Please see Figure 4 The processing component 14 includes a drive motor 141 fixedly connected to the upper side of the processing box 1, a drive rod 142 fixedly connected to the output end of the drive motor 141, a cutter 143 fixedly connected to the drive rod 142, a filter screen 144 fixedly connected to the inner wall of the processing box 1, and a crushing roller 145 rotatably engaged with the drive rod 142 and cooperating with the filter screen 144. The drive motor 141 drives the drive rod 142 and the cutter 143 to rotate and cut the material, and the crushing roller 145 crushes and squeezes the fragments on the filter screen 144.

[0030] Please see Figure 4 The dust removal mechanism 15 includes a high-pressure air pump 151 fixedly connected to one side of the processing box 1, a conveying pipe 152 fixedly connected to the output end of the high-pressure air pump 151 and rotatably engaged with the lower end of the drive rod 142, an air guide trough 153 opened at the lower end of the drive rod 142, a connecting pipe 154 fixedly connected to the drive rod 142 and engaged with the air guide trough 153, an air guide frame 155 fixedly connected to one end of the connecting pipe 154 and engaged with the filter screen 144, and a dust removal mechanism 155 fixedly connected to the lower inner wall of the air guide frame 155. The filter cloth 156 on the side is evacuated by a high-pressure air pump 151. The gas enters the air guide trough 153 from the air guide frame 155 and is then drawn out from the air guide trough 153, creating a negative pressure inside the processing box 1. This guides the generated dust and prevents it from flowing out from the inside of the feed inlet 2. After processing a batch, the high-pressure air pump 151 blows air out from the air guide frame 155, cleaning the gaps in the filter screen 144. During this process, the filter cloth 156 can be used for filtration.

[0031] The implementation principle of the water-soluble fertilizer raw material pretreatment device in this application embodiment is as follows: When in use, the treatment box 1 is first placed flat in the corresponding position, and then the drive motor 141 is started to drive the drive rod 142 to rotate, so that the cutting blade 143 rotates. Then, water-soluble fertilizer raw materials are poured into the hopper 6 and enter the treatment box 1 from the inside of the feed inlet 2. Then, the high-pressure air pump 151 draws air from the inside of the conveying pipe 152. The gas is drawn out from the air guide frame 155 and the air guide groove 153, so that the gas inside the treatment box 1 is drawn out, so that the negative pressure is generated inside the treatment box 1. The gas enters from the inner wall of the feed inlet 2, thereby guiding the dust in the treatment process, suppressing the dust generated from the inner wall of the feed inlet 2 during the crushing process, reducing environmental pollution, and optimizing the internal working environment.

[0032] After use, the squeezing block 122 can be operated to squeeze the spring 123, causing the locking block 124 to separate from the limiting plate 13. This allows the telescopic block 9 to be pressed down, releasing the restriction on the lower side of the hopper 6. After the hopper 6 is flipped over, one end of it separates from the upper side of the feed inlet 2. The feed inlet 2 can be protected by rotating the baffle 4, reducing the risk of dust entering the processing box 1 from the inner wall of the feed inlet 2 when not in use, thus ensuring the cleanliness of the processing box 1. After use, the high-pressure air pump 151 can be controlled to blow air. The air is sprayed out from the air guide frame 155, which blows the gaps in the filter screen 144, causing the raw material in the gaps to be blown out, thus achieving cleaning.

[0033] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
