Description

Technical Field

[0001] The utility model relates to the technical field of crushing equipment, and more specifically, to limestone crushing equipment with a dust reduction mechanism. Background Art

[0002] In the production process of limestone powder, crushing equipment is generally used to crush the limestone raw materials into smaller particles. A large amount of dust is easily generated during the material crushing process. In order to reduce dust emissions and prevent environmental pollution, common limestone crushing equipment is usually equipped with a dust reduction mechanism. Common dust reduction equipment is usually composed of multi-layer filters and air suction equipment.

[0003] However, as time goes by, a large amount of dust will gradually accumulate on the filter, causing the filter to become clogged, and the dust can no longer pass through the filter, resulting in a decrease in filtration efficiency or an inability to continue filtering. In order to maintain the filtering effect, the filter needs to be cleaned. When cleaning the filter, the dust attached to the surface of the filter may be released back into the environment, causing secondary pollution. Utility Model Content

[0033] By setting the cover box plate 72, the inner surface of the cover box plate 72 can fit with the side end of the dust reduction box 61, so as to achieve the effect of sealing the dust reduction box 61 during the dust reduction operation, and when cleaning the dust on the surface of the filter plate group 63, it can be covered to prevent the dust from flying to the outside.

[0034] It also includes a support column 4 and a crushing assembly 5. The top of the support column 4 is fixedly installed with the bottom of the supporting plate 3, and the crushing assembly 5 is arranged inside the crushing equipment body 1.

[0035] Among them, the crushing assembly 5 includes a connecting plate 50, a shell 51, and a motor 52. The side of the connecting plate 50 is fixedly installed with the outer surface of the crushing equipment body 1, the side end of the shell 51 is fixedly installed with the surface of the connecting plate 50, and the outer surface of the motor 52 is fixedly installed with the inner surface of the shell 51.

[0036] The crushing assembly 5 further includes a shaft 53, a crushing wheel 54, and a filter plate 55.

In addition, in order to reduce the situation where the dust is scattered and released back into the environment to cause secondary pollution, the staff can pre-inject a certain amount of clean water into the collection box 77 to achieve the dust reduction effect.

[0041] The working process of the utility model is as follows:

[0042] In the process of crushing the limestone raw material, the motor 52 is first started, and the shaft 53 connected to the output end of the motor 52 rotates, driving the externally connected crushing wheel 54 to rotate, so as to crush the input limestone raw material.
