Description

Technical Field

[0001] The utility model relates to the technical field of ventilation and dust removal, in particular to a dust removal system used in a cotton notarization inspection laboratory. Background Art

[0002] Cotton notarization inspection adopts the centralized laboratory inspection mode. Because cotton is a primary processed product, the cotton bales contain impurities such as cotton dust, short fibers, and cotton leaf debris that are harmful to the human body. During the inspection process, the inspectors need to take samples according to the test module test sample weight requirements. During the sampling process, the cotton dust, short fibers and other fine dust in the cotton will be shaken off on the test table and in the air. At the same time, the testing equipment will also produce a small amount of short fibers during the test process. The fine dust such as cotton dust and short fibers floating in the air will be inhaled into the lungs of the inspectors, causing harm to the health of the inspectors.

[0003] To address this issue, some cotton notarization inspection laboratories currently use small dust collectors to filter dust in the air in the inspection room. However, since small dust collectors use the form of upper air intake and lower exhaust, the lower exhaust will blow up the dust deposited on the ground again. Due to the limited air intake of the dust collector, the dust in the air cannot be filtered in time, which will cause secondary harm to the inspectors. Since the cotton notarization inspection laboratory is a constant temperature and humidity laboratory, the wind speed of the small dust collector will affect the constant temperature and humidity environment.

[0004] Therefore, a dust removal system for cotton notarization inspection laboratory is proposed. Utility Model Content
