Workshop air dust purification device and purification method thereof

Abstract

The invention relates to the technical field of dust removal, and discloses a workshop air dust purification device. The workshop air dust purification device comprises dust collection equipment, a bottom plate and a dust collection pipe. The inner wall of the dust collection equipment is provided with a positioning base. The positioning base is internally provided with a positioning rod. The positioning rod does circular motion along the positioning base. The positioning rod is provided with a conical tube. The conical tube is provided with a groove. A sliding block is mounted in the groove.The sliding block is provided with a sliding rod. Through speed buffer of dust, force of dust impacting a filter substrate is greatly reduced, thus, when the filter substrate is impacted, impact forceis insufficient for deformation of the filter substrate, and the durability of the filter substrate during use is improved. Therefore, the filter substrate maintains a relatively good state when filtering dust, the dust filtration complete precision is equal to the previous precision, the dust filtration environment maintains a relatively stable state, and the speed of dust during filtration is further increased.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to a workshop air dust purification device and a purification method thereof. Background technique [0002] Industrial vacuum cleaner is a kind of supporting or cleaning equipment commonly used in industry. It can be used to collect waste, filter and purify air and clean the environment in the process of industrial production. Dust, debris, to ensure the cleanliness of the working environment and the health of employees. [0003] The working principle of the existing workshop air dust purification device is as follows: Figure 5 As shown, the inside of the barrel is vacuumed by multi-stage high-pressure fans, vortex fans, vortex air pumps, etc., so that the negative pressure rises rapidly, and the high negative pressure makes the air quickly flow into the barrel through the air inlet, and the barrel is vacuumed Brush and suction pipe, the flowing air carries solid particles th...

[0003] The working principle of the existing workshop air dust purification device is as follows: Figure 5 As shown, the inside of the barrel is vacuumed by multi-stage high-pressure fans, vortex fans, vortex air pumps, etc., so that the negative pressure rises rapidly, and the high negative pressure makes the air quickly flow into the barrel through the air inlet, and the barrel is vacuumed Brush and suction pipe, the flowing air carries the solid particles that need to be collected and processed into the barrel, the filter bag is connected to the air inlet, the solid is attached to the inner surface of the filter bag, the initially filtered air passes through the gap of the filter bag, and then After the secondary filtration of the filter element, the air can meet the discharge standard. The filtered air enters the exhaust duct through the exhaust port of the fan or air pump, and is finally discharged back into the workshop. With the development of technology and workshop technology, the suction of the vacuum cleaner It is getting bigger and bigger. During the working process of the vacuum cleaner, iron filings, dust and other debris in the workshop will be directly inhaled by the vacuum cleaner. And bag type dust collector, and bag type dust collector is mostly made of glass fiber, chemical fiber, polyester, stainless steel and other filter substrates, filter solids generally use "polyester fiber" filter paper as the substrate, and then carry out surface PTFE coating treatment, During the impact of dust and iron filings, the filter base material will be hit with dents, resulting in the reduction of the accuracy of the filter base material with the impact of dust and iron filings. The small particles of dust inside the vacuum cleaner cannot be filtered, resulting in the dust suction pipe inside the vacuum cleaner Blockage affects the use of the vacuum cleaner, and with the increase of wind force, dust and iron filings hit the filter substrate, causing the noise of the vacuum cleaner to increase with the increase of wind force, resulting in excessive noise inside the workshop and affecting the working environment of the staff. Normal work, further affecting the normal use of the vacuum cleaner
