Description

Technical Field

[0001] The invention relates to the technical field of fertilizer production, and in particular to cooling equipment for fertilizer production that can prevent fertilizer particles from melting. Background Art

[0002] Fertilizer production is a type of fertilizer industry, which is an industrial production department that uses minerals, water, air and other raw materials to manufacture chemical fertilizers through chemical and mechanical processing. It is one of the important components of the chemical industry. The products of the fertilizer industry are mostly inorganic fertilizers. In the industrial department that produces fertilizers, the vast majority of fertilizers are inorganic compounds. Therefore, fertilizer production belongs to inorganic chemical industry. Fertilizer is one of the main means to increase agricultural output. Many fertilizer products and products closely related to fertilizer production are widely used in industry.

[0003] In the prior art, fertilizers often need to be treated at high temperatures during the production process. After the production of fertilizer particles is completed, the high-temperature fertilizer particles need to be cooled. At this time, the cooling treatment of the fertilizer is usually to put the piled fertilizer particles into the cooling equipment for cooling. During this process, the fertilizer particles piled together will be affected by the concentrated heat and partially melted, and then the fertilizer particles will stick to each other into blocks due to melting. The existing fertilizer cooling equipment mostly adopts the stirring and flipping method during feeding and cooling. At this time, the fertilizer inside is still in a pile during the stirring and cooling process. At the same time, under the action of gravity, the fertilizer has the phenomenon of falling into a pile, and then the stirring structure in the cooling equipment cannot completely break up the piled fertilizer particles. Then, in the subsequent cooling process, the fertilizer particles at the bottom cannot be flipped to the top, which will cause uneven cooling and partial surface melting, thereby affecting the particle size of the fertilizer and the subsequent use effect. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a cooling device for fertilizer production that can prevent fertilizer particles from melting, so as to solve the problems raised in the above-mentioned background technology.

The bottom surface of the distribution plate 11 is fixedly installed with a shield 55, which is convenient for adjusting the second driven bevel gear 44 and the active bevel gear 44. The bevel gear 43 and the first driven bevel gear 42 are protected to prevent fertilizer particles from entering between the meshing tooth grooves and affecting use. Two rubber sealing films 48 are fixedly installed on the top and bottom surfaces of the mounting frame 19, and the rubber sealing films 48 are fixedly installed on the inner wall of the mounting shell 17 to prevent fertilizer particles from entering the interior of the mounting shell 17 and affecting use. The outer cylindrical wall surface of the third rotating shaft 27 is fixedly sleeved with a breaking paddle 15, and the outer cylindrical wall surface of the distribution tank 1 is fixedly installed with a discharge channel 5 to facilitate the discharge of the fertilizer particles after cooling from the interior of the distribution tank 1.

[0031] Working principle: Please refer to Figure 1-Figure 13As shown, when in use, the staff pours the fertilizer to be cooled into the interior of the feed barrel 4 through the feed pipe 10 or opens the cover 6. At this time, the piled fertilizer is broken up by the rotation of the multiple breaking paddles 15 and the blades of the positioning frame 16, so that the large lumps of fertilizer are dispersed into small pieces of fertilizer, and then the small pieces of fertilizer will automatically fall to the surface of the distribution plate 11, and then the mounting frame 19 will contact the multiple protrusions on the surface of the distribution plate 11 through the rotation of the mounting frame 19. At this time, the mounting frame 19 rotates The force will be converted into an upward moving force due to the influence of the protrusion, and then the upward movement of the mounting frame 19 will squeeze the return spring 45 inside the mounting shell 17. At the same time, during the upward movement of the mounting frame 19, the multiple rubber pressing plates 47 are rotatably connected to the bottom of the mounting frame 19 and are rotatably connected to the immovable connecting head 50. At this time, during the upward movement of the mounting frame 19, the multiple rubber pressing plates 47 will rotate away from each other, and then the multiple rubber pressing plates 47 will rotate upward to open, and then the mounting frame 19 will rotate upward to open the return spring 45. When the rack 19 leaves the raised part on the surface of the distribution disk 11, the multiple rubber pressing plates 47 will be reset, so that the multiple rubber pressing plates 47 can move up and down reciprocatingly, and squeeze the small pieces of fertilizer on the surface of the distribution disk 11, so that they are dispersed into fertilizer particles and fall through the mesh holes on the surface of the distribution disk 11. At this time, the falling fertilizer particles will fall to the surfaces of the multiple mounting racks 19 inside the mounting cover 12, and then the high-temperature fertilizer particles will contact the copper mounting racks 19, and then the cold circulating coolant inside the cooling tube 20 will continuously perform heat exchange treatment with the high-temperature fertilizer, thereby quickly cooling the fertilizer on the surface of the mounting rack 19 to prevent it from melting and agglomerating due to high temperature again in the future. After the above steps are completed, the staff can drive the pushing rack 22 to discharge the fertilizer particles after the cooling of the surfaces of the multiple mounting racks 19, thereby achieving the effect of breaking up and cooling the fertilizer particles, preventing the fertilizer from agglomerating due to high-temperature melting during the cooling process, and not being easy to be completely cooled.
