Filtering bag suspension structure of bag-type dust collector
The invention discloses a filtering bag suspension structure of a bag-type dust collector. The suspension structure is characterized in that the bottom of an inverted inner-layer filtering bag with inner and outer filtering bags is connected with a suspension ring connected to the inner side of the upper part of an outer bag cage through a suspension part; and the inner-layer filtering bag is internally provided with an anti-closing supporting device. According to the filtering bag suspension structure of the bag-type dust collector disclosed by the invention, filtering area is enlarged through a structure of suspending the inner-layer filtering bag inside the outer bag cage; the inner space of the outer bag cage is utilized, so that the filtering area is enlarged on the premise of not increasing the size of a filtering device; the floor space of the dust collector is saved, and the working amount of civil construction is reduced; and the steel consumption of the dust collector is reduced, and the total cost of the dust collector is reduced. 1. A bag-type dust collector filter bag hanging structure, characterized in that the filter bag comprises an inner, the outer two layers of filter bag, the outer bag is tubular, said outer layer in the inner layer of the bag is provided with an inverted bag, said inner layer with the outer layer of the filter bag is provided with an annular space is formed between the filter bag, the mouth of the inner layer with the outer layer of the filter bag is connected with the bottom of the filter bag; The suspension structure is as follows: the inner layer of the filter bag through the bottom of the suspension member and the suspension ring is connected, the inner filter bag is provided within support device against shuts ; The cage of the cage comprises an outer bag cage outside states the bag , outside bag cage upper ring-shaped cover, the lower annular cover of the outer bag and at least two the suspension ring, the annular cover outside bag cage on the outer bag cage is fixedly connected with the upper end of the reinforcing cage, the lower annular cover outside states the bag the outer bag cage is fixedly connected with the lower end of the reinforcing cage, all the suspension rings are evenly distributed in the outer bag is connected with the upper part of the reinforcing cage the inner side of the cage. 2. Suspension structure of the filter bag according to Claim 1 bag type dust collector, characterized in that the supporting device is states against shuts in the inner bag is provided with a plurality of horizontal support ring. 3. Suspension structure of the filter bag according to Claim 1 bag type dust collector, characterized in that the inner cage for supporting device is states against shuts , in states the bag cage comprises an inner cage for the reinforcement cage, the upper cage for under the cage covers tee and inner bag, in states the bag cage on the annular cover is fixedly connected to the upper end of the inner bag cage steel reinforcement cage, the outer panels in the lower cover is fixedly connected to the lower end of the reinforcement cage cage for; the cage in the outer bag inverted in states the bag cage , in states the bag cage on the with the annular cover is connected with the lower annular cover of the outer bag, the outer bag in states the bag cage and the annular space is formed between the cage. 4. Suspension structure of the filter bag according to Claim 1 bag type dust collector, characterized in that the suspension element is an elastic member.
