Description

Multifunctional filter bag Technical Field The utility model relates to the technical field of filter bags, in particular to a multifunctional filter bag. Background The filter bag has excellent chemical property stability and heat resistance, is representative of the highest performance applied to the filter material industry, is also the variety with the highest performance in all common filter materials, and achieves higher level in the aspects of filter efficiency, filter precision and the like. The filter bag is the key part in the operation process of the bag type dust collector, and generally the cylindrical filter bag is vertically hung in the dust collector, and when gas enters, the filter bag can be spread, dust is attached to the inner surface of the filter bag, and as the quantity of dust increases, the air permeability of the filter bag can be reduced, the filter bag needs to be cleaned regularly, and the filter bag is inconvenient to use and needs to be improved. Disclosure of utility model (One), solve the technical problems The utility model aims to solve the technical problem of overcoming the difficulty and providing the multifunctional filter bag which can support the filter bag body, enable dust to be placed between arc rods and prolong the cleaning period of the filter bag. (II) technical scheme In order to solve the technical problems, the multifunctional filter bag comprises a pipeline and a filter bag body sleeved on the pipeline, wherein the end part of the pipeline is provided with a flange, the filter bag body is sleeved on the flange, and the pipeline is in threaded connection with a mounting piece which is abutted with the flange to fix the filter bag body; The mounting piece is provided with a limiting piece sleeved on the outer side of the filter bag body; The installation piece is provided with a screen cylinder sleeved on the outer side of the limiting piece. As an improvement, the mounting piece comprises a first screw barrel in threaded connection with the pipeline, a second screw barrel and a third screw barrel are fixedly arranged on the first screw barrel, the limiting piece is in threaded connection with the second screw barrel, and the screen barrel is in threaded connection with the third screw barrel. As an improvement, the limiting piece comprises a limiting screw sleeve sleeved on the second screw cylinder, and a plurality of arc rods wrapping the filter bag body are uniformly arranged on the limiting screw sleeve. As an improvement, the screen barrel comprises a screen screw sleeve sleeved on the third screw barrel, and a screen sleeved on the limiting piece is fixedly arranged on the screen screw sleeve. As an improvement, an elastic rope is arranged at the opening of the filter bag body. (III) beneficial effects Compared with the prior art, the utility model has the advantages that: 1. The flange, the pipeline and the first screw cylinder on the mounting piece are matched, so that the filter bag body can be fixed; 2. The limiting piece comprises a limiting threaded sleeve and arc rods, the arc rods can support the filter bag body, dust is concentrated in the filter bag body between the arc rods, the position where the filter bag body contacts with the arc rods keeps ventilation, and the cleaning period of the filter bag body is prolonged; 3. the screen cylinder can carry out limit support to the filter bag body, prevents that the air current from being too big from propping the filter bag body open.
