Description

Technical Field

[0001] The utility model relates to the technical field of potassium sulfate wet process granule production, in particular to a potassium sulfate wet process granule production crushing system. Background Art

[0002] The existing process of potassium sulfate wet granule production and crushing mainly uses potassium sulfate powder mixed with a certain proportion of water as raw material, which enters the granulation host through the raw material scraper for granulation. The granulation host has a crushing function, and the material after large particle crushing enters the particle belt, and enters the screening machine to screen out pre-finished particles, small particles and powder. The pre-finished particle belt participates in the subsequent production process, and the small particles and powder return to the raw material scraper through the return scraper to continue to participate in granulation. This equipment installation layout not only causes the return scraper and return hopper to lift a large load, and the granulation rate is low, but also often causes the granulation host to be blocked, requiring shutdown for cleaning, resulting in production not being able to proceed smoothly, affecting product output and quality. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a potassium sulfate wet granule production and crushing system, which removes the mechanical crushing function of the granulation host, replaces the screening machine with a multi-layer screening machine, and adds a large particle belt, a centralized crusher, and a crushing belt. By adopting centralized crushing of large particles, the granulation host is prevented from being blocked, the load of the return scraper is reduced, and the granulation rate is improved.

[0004] To achieve this technical purpose, the utility model adopts the following scheme:

[0005] A potassium sulfate wet-process granule production and crushing system comprises a granulating main machine, wherein a raw material scraper is arranged at the feeding end of the granulating main machine, a discharging end of the granulating main machine is connected to an intermediate bucket elevator through a particle belt, the intermediate bucket elevator is connected to a multi-layer particle screening machine, and a pre-finished product particle belt is arranged at the discharging end of the multi-layer particle screening machine; the multi-layer particle screening machine is connected to a centralized crusher through a large particle belt, and the centralized crusher is connected to the intermediate bucket elevator through a crushing belt; the multi-layer particle screening machine is connected to a return bucket elevator through a return scraper, and the return bucket elevator discharging end is connected to the raw material scraper.

[0006] Compared with the prior art, the beneficial effects of the present invention are:

[0007] The utility model cancels the mechanical crushing function of the granulating main machine, avoiding the blockage of the granulating main machine; at the same time, it adds a large particle belt, a centralized crusher, and a crushing belt, a large particle processing process, reduces the load of the return scraper, and improves the granulation rate. The utility model has the advantages of stability and high efficiency, and has good economic benefits.

[0008] Furthermore, the granulation main machine is an extrusion molding machine, which cancels the mechanical crushing function of the granulation main machine, reduces the blockage of the equipment, and ensures the smooth progress of production.

[0009] Furthermore, the multi-layer particle screening machine includes at least two layers of screens, which screen potassium sulfate particles into pre-finished product particles, small particle size particles and powder, and large particle size particles. The multi-layer particle screening machine is provided with a large particle discharge port, a pre-finished product particle discharge port, and a small particle and powder discharge port. The large particle size particles enter the crusher through the large particle discharge port via the large particle belt for crushing, and after crushing, they return to the multi-layer particle screening machine through the intermediate bucket elevator for screening; the pre-finished product particles enter the subsequent production process through the pre-finished product particle discharge port via the pre-finished product particle belt; the small particle size particles and powder enter the return scraper through the small particle and powder discharge port, and return to the granulation main machine through the return bucket elevator to continue participating in granulation.

[0010] Furthermore, the raw material scraper is connected to the return scraper, aiming to transport the excess material in the raw material scraper to the return scraper to prevent the blockage of the raw material scraper caused by insufficient processing capacity of the granulation main machine.
