Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a flexible dust filtering device of a dust collector. Background Art

[0002] The pulse bag dust collector adopts the chamber-stopped air pulse jet cleaning technology, which overcomes the shortcomings of conventional pulse dust collectors and chamber back-blowing dust collectors. It has strong cleaning ability, high dust removal efficiency and low emission concentration. It is suitable for the purification of dust-containing gases and the recovery of materials in the metallurgy, building materials, cement, machinery, chemical industry, electric power and light industry industries.

[0003] Chinese patent publication number CN203196480U discloses a pulse filter bag dust collector. The pulse filter bag dust collector comprises a housing with an air inlet flange and an air outlet flange. The interior of the housing is divided into multiple air chambers, each equipped with an air duct baffle. Dust filter bags are installed in each air chamber through a filter bag panel. An upper housing is located above the housing, equipped with a pulse dust cleaning device and an air storage tank. An ash hopper is located below the housing. An auger is located in the lower portion of the ash hopper. A ladder is provided on one side of the housing.

[0004] In the above technical solution, the dust filter bag is installed on the filter bag panel. In order to improve the filtering ability of the dust-collecting gas, multiple dust filter bags will be installed on the filter bag panel. The dust filter bag has a certain service life. After the service life is reached, the dust filter bag needs to be replaced. Because the upper end of the dust filter bag is fixed on the filter bag panel, the lower end of the dust filter bag extends to the ash hopper. At this time, when removing the dust filter bag, it is necessary to remove it together with the bag cage. Since the bag cage cannot be bent, a certain avoidance space is required above the dust collector for the bag cage to be pulled out of the dust collector, which requires a high installation space and has poor adaptability. Summary of the Invention

[0005] The purpose of the utility model is to solve the problems in the prior art and to provide a flexible dust filtering device for a dust collector, which has low requirements for installation space and good adaptability.

[0006] To achieve the above-mentioned purpose, the utility model proposes a flexible dust filtering device for a dust collector, comprising a bag cage and a filter bag detachably mounted on the bag cage, wherein the bag cage comprises a plurality of cage bodies and a plurality of elastic connectors, and the ports of two adjacent cage bodies are fixedly connected by an elastic connector.

[0007] Preferably, the bag opening of the filter bag is provided with an annular body detachably connected to the filter bag flower plate.

[0008] Preferably, a connecting sleeve is provided at the lower end of the annular body, which passes through the filter bag plate and extends into the bag opening of the filter bag, and the filter bag is fixedly connected to the connecting sleeve via a throat clamp.

[0009] Preferably, a protective sleeve is provided between the throat clamp and the filter bag.

[0010] Preferably, the upper end of the cage body at the top is provided with a flange, which is pressed on the upper end of the annular body. The filter bag plate is provided with a plurality of nuts arranged around the annular body, and the flange is fixedly connected to the nuts by bolts.

[0011] Preferably, a sealing gasket is provided between the annular body and the filter bag plate and flange.

[0012] Preferably, a positioning ring is provided on the lower end of the filter bag, and the positioning ring is fixedly connected to the dust collector housing through a connecting beam.

[0013] Preferably, a filter bag anti-wear layer is provided between the positioning ring and the filter bag.

[0014] Beneficial effects of the present invention: The bag cage of the present invention includes a plurality of cage bodies and a plurality of elastic connectors. The ports of two upper and lower adjacent cage bodies are fixedly connected by the elastic connectors, so that the bag cage pulled out of the dust collector can be bent and deformed, effectively reducing the requirements for the space above the dust collector. Compared with the existing technology, it can have low requirements for installation space and good adaptability.

[0015] The features and advantages of the present invention will be described in detail through embodiments with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
