Description

Technical Field

[0001] This utility model belongs to the field of compound fertilizer production technology, and specifically relates to a pulping equipment for high-tower compound fertilizer production. Background Technology

[0002] The pulping equipment in high-tower compound fertilizer production is a key pre-processing device in the high-tower granulation process. It is mainly used to put solid or liquid raw materials such as urea, monoammonium phosphate, and potassium chloride into the pulping tank according to the formula ratio. Under heating (usually 120°C to 150°C) and stirring conditions, the raw materials are fully melted, dissolved and homogenized to form a high-temperature molten slurry with good fluidity and uniform composition. Then it is conveyed to the nozzle at the top of the high tower for atomization granulation, and finally cooled and formed into granular compound fertilizer.

[0003] Existing high-tower compound fertilizer production equipment mixes solid or liquid raw materials such as nitrogen, phosphorus, and potassium (e.g., urea, monoammonium phosphate, potassium chloride, water, etc.) according to the formula ratio, dissolves and homogenizes them under heating and stirring conditions, forming a high-temperature molten slurry with good fluidity. However, its stirring mechanism is simple and fixed, and the stirring range of the fixed stirrer is limited, making it difficult to cover the entire area of ​​the tank. In particular, "dead zones" are easily formed on the tank walls, bottom and corners, resulting in uneven mixing of raw materials, with localized high concentrations or incompletely dissolved particles. Furthermore, the single stirring method is difficult to achieve vertical convection and three-dimensional tumbling of compound fertilizer raw materials, resulting in the upper layer of compound fertilizer raw materials being suspended and the lower layer settling, affecting the homogenization effect. To achieve a basic mixing effect, the stirring time needs to be extended, increasing energy consumption and reducing the overall production pace. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a pulping device for high-tower compound fertilizer production. It can fully and comprehensively mix the compound fertilizer raw materials by using a lifting and tumbling mechanism in conjunction with a stirring mechanism. It can also force convection with the upper layer of compound fertilizer raw materials to break the "layering" phenomenon, ensuring that components such as nitrogen, phosphorus, and potassium are evenly distributed. Moreover, the tumbling action expands the stirring area, eliminates mixing dead zones, improves pulping uniformity, and reduces the pulping time required.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a pulping device for high-tower compound fertilizer production, including a barrel body, an arc-shaped heating element inside the barrel body, a rotating cylinder rotatably mounted at the upper end of the barrel body, a rotating frame mounted on the outer arc surface of the rotating cylinder, the rotating cylinder and the rotating frame being fixed together by welding, multiple stirring columns inside the rotating frame, a driving mechanism for driving the rotating cylinder to rotate at the upper end of the outer arc surface of the barrel body, and a lifting and tumbling mechanism inside the barrel body, the lifting and tumbling mechanism including a hollow frame mounted at the upper end of the barrel body, the upper end of the hollow frame being located inside the rotating cylinder and coaxial with it, a movable hollow frame slidably mounted inside the hollow frame, and the outer side of the movable hollow frame... Multiple lifting plates are provided on the surface. Guide frames are provided on the left and right sides of the cavity frame, with the left and right positions of the two guide frames corresponding. A movable rotating seat is slidably provided inside each guide frame. A tumbling frame located inside the guide frame is provided on the outer surface of each rotating seat. A rotating connecting rod is rotatably provided inside each movable rotating seat. Each rotating connecting rod is rotatably connected to the interior of the adjacent fixed base. A lead screw located inside the cavity frame is rotatably provided at the upper end of the barrel. The movable hollow frame is threadedly connected to the lead screw. A second drive unit for driving the lead screw to rotate is provided at the upper end of the barrel. The second drive unit includes a second motor located at the upper end of the barrel. The output shaft of the second motor is connected to the upper end of the lead screw through a coupling.

[0006] As a further improvement of this utility model, the driving mechanism includes a gear 1 that is rotatably mounted inside the upper part of the barrel via a rotating column, a gear 2 that is mounted on the outer arc surface of the rotating cylinder, and gear 2 and gear 1 meshing together. A driving unit 1 that drives gear 1 to rotate is mounted at the upper part of the barrel. The driving unit 1 includes a motor 1 mounted at the upper part of the barrel. The output shaft of motor 1 is connected to the upper part of the rotating column via a coupling. A protective plate is mounted at the upper part of the barrel, and a circular hole adapted to the rotating cylinder is opened in the middle of the protective plate.

[0007] As a further improvement of this utility model, a support frame is provided on the outer arc surface of the barrel body, and multiple mounting plates are provided at the lower end of the support frame. The support frame and the mounting plates are fixed together by welding, and multiple mounting holes are provided inside each mounting plate.

[0008] As a further improvement of this utility model, the upper end of the barrel is provided with a feed shell and a liquid inlet pipe, and the feed shell and the liquid inlet pipe are connected to the interior of the barrel. The lower end of the barrel is provided with a drain pipe, which is connected to the interior of the barrel. A solenoid valve is connected in series in the middle of the drain pipe.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, by controlling the activation of the arc-shaped heating element to preheat the inside of the tank, the initial temperature inside the tank can be effectively increased. Then, the compound fertilizer raw materials are added into the tank through the feed shell and liquid inlet pipe. The motor is then started to drive the gear one to rotate, thereby driving the rotating drum and rotating frame to operate, so that the stirring column can stir the materials in all directions. Under continuous heating conditions, it promotes the rapid melting and uniform mixing of raw materials such as urea, achieving efficient pulping. After pulping is completed, all electrical components are turned off, and the solenoid valve is automatically opened to allow the molten slurry to be smoothly discharged from the drain pipe, thus improving the stability, safety and continuity of the pulping process.

[0011] Secondly, by controlling the motor to operate in both forward and reverse directions, the lifting plate on the threaded hollow frame moves up and down repeatedly, lifting the denser compound fertilizer deposited at the bottom of the barrel. As the hollow frame moves up and down, the fixed base connected to it moves up and down, causing the internal rotating connecting rod to rotate and contract or expand. This causes the tumbling frames on both sides of the rotating base to move or expand towards each other, thoroughly tumbling the compound fertilizer raw materials inside the barrel. Combined with the stirring column on the rotating frame, the compound fertilizer raw materials are comprehensively lifted, tumbled, and stirred for pulping. The lifting and tumbling mechanism, in conjunction with the stirring mechanism, ensures thorough and comprehensive mixing of the compound fertilizer raw materials. It also allows for forced convection with the upper layer of compound fertilizer raw materials, breaking the "stratification" phenomenon and ensuring the uniform distribution of components such as nitrogen, phosphorus, and potassium. Moreover, the tumbling action expands the stirring area, eliminates mixing dead zones, improves pulping uniformity, and reduces the pulping time.

[0012] Thirdly, during the process of lifting, tumbling, and mixing the compound fertilizer raw materials, the protective plate can effectively shield the meshing parts of gear one and gear two, preventing high-temperature and high-humidity compound fertilizer raw materials from entering the gear gap, avoiding gear jamming, wear, or corrosion, thereby ensuring the normal operation of the transmission system, extending the service life of the equipment, reducing mechanical failures and downtime caused by compound fertilizer raw material contamination, ensuring continuous and stable operation of the mixing process, and improving the safety and reliability of the equipment.

[0013] Fourth, the support frame can keep the tank body firmly in a vertical position, ensuring that the mixing system is subjected to uniform force during operation and avoiding vibration, eccentric wear or mechanical failure caused by tilting or shaking. At the same time, by inserting the mounting bolts into the mounting holes, the pulping equipment can be firmly fixed to the ground, effectively enhancing the overall stability of the equipment and preventing displacement or overturning during operation.

Detailed Implementation

[0017] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0018] like Figure 1 , 2As shown in Figure 3, a pulping device for producing high-tower compound fertilizer includes a barrel 101. An arc-shaped heating element 105 is installed inside the barrel 101. A rotating cylinder 204 is rotatably mounted on the upper part of the barrel 101. A rotating frame 202 is mounted on the outer arc surface of the rotating cylinder 204. Multiple stirring columns 203 are installed inside the rotating frame 202. A driving mechanism for driving the rotating cylinder 204 to rotate is installed at the upper part of the outer arc surface of the barrel 101. A lifting and tumbling mechanism is installed inside the barrel 101. The driving mechanism includes a gear 205 rotatably mounted on the upper part of the barrel 101 via the rotating columns, and a gear 205 mounted on the outer arc surface of the rotating cylinder 204. 206, Gear 206 and Gear 1 205 are meshed and connected. The upper end of the barrel 101 is provided with a drive unit 1 that drives Gear 1 205 to rotate. The drive unit 1 includes a motor 201 located at the upper end of the barrel 101. The output shaft of the motor 201 is connected to the upper end of the rotating column through a coupling. The upper end of the barrel 101 is provided with a feed shell 102 and a liquid inlet pipe 103, and the feed shell 102 and the liquid inlet pipe 103 are connected to the interior of the barrel 101. The lower end of the barrel 101 is provided with a drain pipe 108, which is connected to the interior of the barrel 101. A solenoid valve 109 is connected in series in the middle of the drain pipe 108.

[0019] By controlling the operation of the arc-shaped heating element 105, the inside of the barrel 101 is preheated. Then, the compound fertilizer raw materials are added into the inside of the barrel 101 through the feed shell 102 and the liquid inlet pipe 103. Then, by controlling the operation of the motor 201, the output shaft drives the gear 205 on the rotating column to rotate, which in turn drives the gear 206 meshing with it to rotate, which drives the rotating frame 202 on the rotating cylinder 204 to rotate. The compound fertilizer raw materials are heated, mixed and pulped by the stirring column 203 on the rotating frame 202. After the mixing and pulping are completed, all electrical components are turned off by controlling the operation, and the solenoid valve 109 is opened by controlling the operation, so that the slurry is discharged from the inside of the drain pipe 108.

[0020] like Figure 1 As shown, a support frame 104 is provided on the outer arc surface of the barrel 101. Multiple mounting plates 106 are provided at the lower end of the support frame 104. Multiple mounting holes are provided inside each mounting plate 106. The support frame 104 can make the barrel 101 stably vertical, and the pulping equipment can be stably fixed by inserting mounting bolts into the mounting holes.

[0021] like Figure 2 , 3As shown in Figure 4, the lifting and tumbling mechanism includes a hollow frame 302 disposed at the upper end of the barrel 101. The upper end of the hollow frame 302 is located inside the rotating cylinder 204 and is coaxial with it. A movable hollow frame 303 is slidably disposed inside the hollow frame 302. Multiple lifting plates 304 are disposed on the outer surface of the movable hollow frame 303. Guide frames 305 are respectively disposed on the left and right sides of the hollow frame 302. A movable rotating seat 310 is slidably disposed inside each guide frame 305. A tumbling frame 306 located inside the guide frame 305 is disposed on the outer surface of each rotating seat. Each movable rotating seat 310 has a rotating connecting rod 307 rotatably installed inside, and each rotating connecting rod 307 is rotatably connected to the interior of the adjacent fixed base 309. The upper end of the barrel 101 is rotatably equipped with a lead screw 308 located inside the cavity frame 302. The movable hollow frame 303 is threadedly connected to the lead screw 308. The upper end of the barrel 101 is equipped with a second drive unit for driving the lead screw 308 to rotate. The second drive unit includes a second motor 301 installed at the upper end of the barrel 101. The output shaft of the second motor 301 is connected to the upper end of the lead screw 308 through a coupling.

[0022] When mixing compound fertilizer, the motor 301 is turned on to run in both directions. The output shaft drives the lead screw 308 to rotate, which in turn drives the lifting plate 304 on the threaded hollow frame 303 to move up and down repeatedly. This lifts up the dense compound fertilizer deposited at the bottom of the barrel 101. As the hollow frame 303 moves up and down, the fixed base 309 connected to it moves up and down, causing the rotating connecting rod 307 inside to rotate, contract, or expand. This causes the tumbling frames 306 on the two movable rotating seats 310 on both sides to move or expand towards each other, fully tumbling the compound fertilizer raw materials inside the barrel 101. This, combined with the stirring column 203 on the rotating frame 202, comprehensively lifts, tumbles, and stirs the compound fertilizer raw materials to make pulp.

[0023] According to another embodiment of the present invention, such as Figure 2 , 3 As shown in Figure 4, a protective plate 107 is provided at the upper end of the barrel 101. A round hole adapted to the rotating cylinder 204 is opened in the middle of the protective plate 107. When the compound fertilizer raw materials are lifted, tumbled and stirred, the protective plate 107 can shield the gear 1 205 and gear 2 206 to prevent the compound fertilizer raw materials from being contaminated and causing the machine to malfunction.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
