Description

Technical Field

[0001] The utility model belongs to the technical field of dust collecting filter bags for dust collectors, and in particular relates to a water-repellent and oil-proof dust collecting filter bag for a pulse bag type dust collector. Background Art

[0002] The pulse bag dust collector is an improved atmospheric pollution control equipment based on the cloth bag dust collector. It is widely used in flue gas dust control and is used in many industries for its small size, high efficiency, and large air volume. The pulse bag dust collector suspends the filter bag through the flower plate. The surface of the flower plate is porous, and the filter bag is mainly fixed to the inside of the flower plate by the expansion ring. The expansion ring must bear the weight of the filter bag and maintain the sealing effect of the contact surface between the filter bag and the flower plate. As the use time increases, the filter bag can be regarded as one of the important components of the bag dust collector. The selection of the filter bag is crucial, which directly affects the dust removal effect of the bag dust collector.

[0003] Patent application number 202321819334.2 discloses a pulse bag dust collector, including an upper box body for discharging clean gas; a lower box body, the lower box body is used to purify dust-containing gas, and the lower box body is fixedly connected to the bottom of the upper box body; a flower plate, the flower plate is installed inside the lower box body, a filter bag is passed through the internal circular hole of the flower plate, and an expansion ring is sewn on the top of the filter bag; a limiting step, the limiting step is located at the top opening edge of the internal circular hole of the flower plate, the side wall of the limiting step is provided with a groove, and the expansion ring is embedded in the interior of the limiting step.

[0004] The above technical solution utilizes an expansion ring to support the dust filter bag, and adopts a threaded limit plate to keep the expansion ring and the dust filter bag fixed. However, since the expansion ring can only support the opening of the dust filter bag, the dust filter bag is susceptible to dust and impurities sticking to the inner wall during use, resulting in adsorption on the inner wall, which makes it impossible to position the dust filter bag after installation. The dust filter bag after adsorption on the inner wall will affect its dust collection and filtration efficiency. Utility Model Content
