Description

Technical Field

[0001] This utility model relates to the field of calcium magnesium phosphate fertilizer technology, specifically a water cooling system for calcium magnesium phosphate fertilizer production. Background Technology

[0002] Calcium magnesium phosphate fertilizer, also known as molten magnesium phosphate fertilizer, is a glassy aluminosilicate containing phosphate ions and is a multi-element fertilizer. Its aqueous solution is alkaline, which can improve acidic soils. It is effective as a base fertilizer when cultivating seedlings, allowing plants to slowly absorb the necessary nutrients. Calcium magnesium phosphate fertilizer is typically produced by melting phosphate rock and magnesium- and silicon-containing ores in an electric furnace, blast furnace, or open-hearth furnace at 1350-1500℃. The melt is then rapidly cooled with water to form a glassy material with a particle size of less than 2mm. After drying and grinding, the final product provides not only a low concentration of phosphorus (12%-18%) but also significant amounts of silicon, calcium, and magnesium. Water quenching of the melt is a crucial step in the production of calcium magnesium phosphate fertilizer.

[0003] A search revealed Chinese patent application number 202022706856.4, which discloses a water-cooling system for calcium magnesium phosphate fertilizer production. The system includes a machine base. A feeding cylinder is vertically and vertically embedded in the middle of the right side of the machine base. A servo motor is vertically and vertically fixed in the middle of the upper part of the feeding cylinder. The drive end of the servo motor is vertically and vertically connected to a spiral feeding roller movably inserted into the inner cavity of the feeding cylinder. This invention utilizes the servo motor to drive the spiral feeding roller to rotate. A cylinder, through a piston rod, drives a baffle plate to separate the fertilizer from the feed inlet of the feeding cylinder. The fertilizer, cooled in a water quenching tank, enters the feeding cylinder, is conveyed by the spiral feeding roller to the outlet, discharged into the feeding hopper, and finally transported to a material cart for transport. The entire process has good continuity, avoiding the problem in existing technologies where fertilizer in the water quenching tank needs to wait for the grab bucket to handle it, thus affecting production efficiency.

[0004] Although the aforementioned patents have solved the problem of waiting time required for fertilizer to be grabbed by the grab bucket in the existing technology, in actual use, simply using a semiconductor cooling plate to cool the water is slow in terms of water temperature reduction. Moreover, during the discharge process, some cooling water is prone to flow out of the discharge port along with the conveying mechanism, requiring frequent addition of cooling water, which wastes water resources, affects the water quenching effect, and causes inconvenience to users.

[0005] Therefore, it is necessary to modify it by using a circulation mechanism to circulate the cooling water, thereby accelerating the temperature drop, and at the same time, extracting the water inside the conveying mechanism to prevent the cooling water from flowing out of the outlet and affecting the water quenching effect. Utility Model Content

[0006] To address the problems mentioned in the background art, the present invention aims to provide a water cooling system for the production of calcium magnesium phosphate fertilizer. This system features a circulating mechanism that circulates cooling water to accelerate temperature reduction, while simultaneously extracting water from the conveying mechanism to prevent it from flowing out of the discharge port and affecting the water quenching effect. This solves the problems of slow temperature reduction when using a semiconductor cooling plate alone, and the tendency for cooling water to flow out of the discharge port during the discharge process, requiring frequent addition of cooling water, wasting water resources, affecting the water quenching effect, and causing inconvenience to users.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a water cooling system for calcium magnesium phosphate fertilizer production, comprising a feeding cylinder, an inlet located on the lower left side of the feeding cylinder, an outlet located on the upper right side of the feeding cylinder, a servo motor fixedly connected to the top of the feeding cylinder, a spiral feeding roller disposed inside the feeding cylinder, the output end of the servo motor penetrating into the interior of the feeding cylinder and fixedly connected to the top end of the spiral feeding roller, a water quenching tank disposed on the left side of the feeding cylinder, a sealing cover slidably connected to the left side of the feeding cylinder for use with the inlet, and a support plate fixedly connected to the upper left side of the feeding cylinder. The system includes a cylinder, the output end of which is fixedly connected to the top of a sealing cover. A housing is fixedly connected to the left side of the water quenching tank. A semiconductor refrigeration plate is installed inside the housing, with the cold end of the semiconductor refrigeration plate in contact with the left side of the water quenching tank. A cooling fan located outside the hot end of the semiconductor refrigeration plate is installed inside the housing. A disassembly ring is threaded to the bottom of the feeding cylinder. A removable filter plate is installed inside the disassembly ring. A connector is threaded to the bottom of the disassembly ring. A connecting pipe is connected to the bottom of the connector. A water pump is connected to the front end of the connecting pipe. The output end of the water pump extends to the top of the water quenching tank.

[0008] As a preferred embodiment of this invention, a sealing ring is fixedly connected to the bottom of the conveying cylinder, and the surface of the sealing ring is in contact with the inner wall of the disassembly ring.

[0009] As a preferred embodiment of this utility model, a filter box is provided on the top of the water quenching tank, the output end of the water pump is connected to the upper front of the filter box, and a secondary filter element is fixedly connected to the lower part of the filter box.

[0010] As a preferred embodiment of this utility model, T-shaped strips are fixedly connected to both the front and rear sides of the right side of the sealing cover, and T-shaped grooves that cooperate with the T-shaped strips are opened on both the front and rear sides of the left side of the conveying cylinder, and the surface of the T-shaped strips is slidably connected to the inner wall of the T-shaped grooves.

[0012] As a preferred embodiment of this utility model, a counterweight base is fixedly connected to the bottom of the water quenching tank and the right side of the conveying cylinder, and a buffer pad is fixedly connected to the bottom of the counterweight base, and the surface of the buffer pad is provided with friction texture.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a feeding cylinder, sealing plate, cylinder, water quenching tank, discharge port, and semiconductor cooling plate in combination to water quench and transport fertilizer. Its working principle is the same as that of prior art document 202022706856.4. By setting up a cooling fan, the heat generated by the semiconductor cooling plate can be dissipated in time, ensuring the normal operation of the semiconductor cooling plate. By disassembling the ring, filter plate, connectors and connecting pipes, and setting up a water pump, the water in the feeding cylinder can be pumped out and transported back to the water quenching tank, realizing water recycling and saving water resources. The filter plate can filter impurities in the water, ensuring the quality of the returned water. Thus, by using a circulation mechanism to circulate the cooling water, the water temperature drops faster. At the same time, the water inside the conveying mechanism is pumped out to prevent the cooling water from flowing out of the discharge port and affecting the water quenching effect.

[0015] 2. By setting a sealing ring, the surface of which fits into the inner wall of the disassembly ring, this utility model enhances the sealing performance of the connection between the conveying cylinder and the disassembly ring, prevents water and material leakage, and ensures the normal operation of the water cooling system and the cleanliness of the production environment.
