Description

Technical Field

[0001] The utility model belongs to the technical field of compound fertilizer processing equipment, and particularly relates to a vibrating screen with a screen mesh that can be quickly disassembled and assembled. Background Technique

[0002] Today's compound fertilizers refer to chemical fertilizers containing two or more nutrient elements. The drum granulator is one of the key equipment in the compound fertilizer industry. Its main working method is pellet wet granulation. Through a certain amount of water or steam, the basic fertilizer is humidified in the cylinder and undergoes sufficient chemical reactions. Under certain liquid-phase conditions, with the rotation of the cylinder, the material particles are agglomerated into balls by the extrusion force between them. However, the current compound fertilizer drum granulation devices usually lack a screening function, and the screening structure is difficult to quickly disassemble and assemble, making it difficult to quickly screen out fertilizer particles of different particle sizes.

[0003] Currently, the utility model patent with the patent number CN201921978262.X discloses a compound fertilizer granulation device with a screening function, including a device main body and a screening and granulation mechanism. The device main body includes a box body, a feeding port, a filter mesh frame, a housing, an aggregate tank, and a screen plate. The feeding port is opened at the top of the box body, the filter mesh frame is connected inside the box body, the aggregate tank is arranged at the bottom inside the box body, the housing is fixed on the box body, and the screen plate is arranged above the aggregate tank inside the box body. This device combines the screening and granulation mechanisms into one through a chain, a motor, an annular rack, a toothless gear, a first rotating shaft, a first roller, a transmission sprocket, a second rotating shaft, a second roller, and a driving sprocket, simplifying the process and optimizing the procedure. However, the current compound fertilizer drum granulation devices usually lack a screening function, and the screening structure is difficult to quickly disassemble and assemble, making it difficult to quickly screen out fertilizer particles of different particle sizes.

[0004] Therefore, in view of the above-mentioned problems that the current compound fertilizer drum granulation devices usually lack a screening function and the screening structure is difficult to quickly disassemble and assemble, a vibrating screen with a screen mesh that can be quickly disassembled and assembled is designed to enable the compound fertilizer drum granulation device to have a screening function and the screening structure to be quickly disassembled and assembled, so as to obtain fertilizer particles of different particle sizes.

Positioning columns 362 are provided at the four corners of the bottom of the screen plate 361. Lock holes 363 are opened in the middle of both sides of the plate body of the screen plate 361;

[0030] Positioning holes 371 are opened at the front and rear ends of the mounting plate 37. A locking block 372 protruding upward is provided in the middle of the mounting plate 37. During installation, the positioning columns 362 extend into the positioning holes 371, and the locking block 372 passes through the lock holes 363 and is locked with the lock nut 364.

[0031] By adopting the above structure, the screen structure 36 can be detachably installed on the mounting plate 37 of the vibration box 3, thus facilitating the quick replacement of the screen plate 361. The specific installation method is to correspondingly insert the positioning posts 362 of the screen plate 361 into the positioning holes 371 on both sides of the mounting plate 37. At this time, the locking blocks 372 on the mounting plate 37 will pass through the locking holes 363. Finally, lock the lock nut 364 on the locking block 372. The up and down movement of the screen plate 361 is restricted by the lock nut 364, and the left and right movement of the screen plate 361 is restricted by the positioning posts 362 and the positioning holes 371. When disassembling, loosen the lock nut 364 and take out the screen plate 361 upward. Both installation and disassembly are very convenient.

[0032] The locking blocks 372, the locking holes 363 and the lock nuts 364 are all rounded rectangular in shape, and the connection method between the lock nuts 364 and the locking blocks 372 is a mortise and tenon connection method with concave-convex combination.
