Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal, and in particular relates to a pulse dust collector which is convenient for replacing filter bags. Background Art

[0002] Bag dust collectors are widely used to purify dusty gases generated by industries such as metallurgy, mining, chemicals, cement, power generation, and grain processing. The working principle of a bag dust collector is to introduce dusty gas into the dust collector and pass it through the filter bags in the dust collector. The dust particles are intercepted and retained on the surface of the filter bags to form a dust layer. The clean air passes through the filter bags and then exits the dust collector. The "pulse dust collector that is easy to replace filter bags" disclosed in the application number "CN201911062898.4" is also an increasingly mature technology. When it is necessary to clean the dust particles generated in the industrial production process, a pulse dust collector can be used to collect dust and particles in the air. The filter bag is an important component of the pulse dust collector, which is mainly responsible for filtering and collecting dust particles. As time goes by, the filter bags will gradually become clogged and worn, causing the efficiency and performance of the dust collector to decrease. However, the device also has the following defects: When the above-mentioned equipment is in use, the filter bags of the dust collector need to be replaced regularly during use. However, when replacing the filter bags of existing dust collectors, they need to be replaced and fixed manually in sequence. The procedure is cumbersome and affects the efficiency. After collecting dust in the air, the existing dust collector will discharge the filtered gas through the air outlet. Unpurified particles will be discharged along with the dust removal effect.
