Tubesheet structure of cloth bag dust remover

Abstract

The invention discloses a tubesheet structure of a cloth bag dust remover, for solving the problems of inaccurate positioning, inaccurate timing blowing, non-uniform complete coverage, easiness in damaging a filter bag, influence on the service life of the filter bag, and the like existing in the existing tubesheet structure of the cloth bag dust remover. The tubesheet structure is characterized by uniformly arranging a plurality of long eyelets (2) convenient for air-flow to pass through on a tubesheet (1) along radial direction radially by using a circular hole (3) as a center, and forming a plurality of concentric circles, thus the advantages of accurate positioning, accurate timing blowing, uniform complete coverage, unbiased blowing, difficulty in damaging the filter bag, prolongation of the service life of the filter bag, and the like can be achieved.

Description

technical field [0001] The present invention relates to a bag type dust collector, in particular to a cloth bag dust collector which is provided with a round hole at the center of the flower plate to facilitate the passage of the main blowing pipe and a plurality of long holes arranged on the flower plate to facilitate the passage of airflow. The flower plate structure of the device. Background technique [0002] At present, such a flower plate structure of a bag filter is disclosed on the market. Its structural features are: a round hole is provided at the center of the flower plate to facilitate the passage of the main blowing pipe and a plurality of holes are arranged on the flower plate to facilitate The long holes through which the blowing air passes divide the circular flower plate into four identical parts from the axial direction, and a plurality of long holes are evenly distributed in a plurality of L shapes on the flower plate of each part. In the diameter direct...

Problems solved by technology

[0002] At present, such a flower plate structure of bag filter is disclosed on the market. The round hole through which the main pipe passes and a number of long holes arranged on the flower plate to facilitate the passage of the blowing air flow. Viewed from the axial direction, the circular flower plate is divided into the same four parts. In each part of the flower plate A plurality of long eyelets are evenly distributed in a plurality of L shapes. In the diameter direction, a plurality of long eyelets form a plurality of concentric circles with different diameters centered on a circular hole. Each long eyehole is perpendicular to the diameter of the flower plate. After adopting this structure, a plurality of evenly distributed blowing pipes placed above the flower board and connected to the main blowing pipe rotate at a constant speed, and the air in the blowing pipe is blown to the long eye holes on the flower board through the blowing port. To achieve the purpose of removing the dust installed on the filter bag with long holes, but because the blowing pipe is rotating at a constant speed with the round hole as the center, the airflow blown out of the blowing pipe is continuously sprayed to the flower plate, and the flower plate The long eye holes on the spray pipe are evenly distributed in an L shape, and the blowing port on the spray pipe is not easy to align with the long eye holes on the flower plate. The center of the bag makes the cleaning effect of the filter bag unsatisfactory, the utilization efficiency of the compressed airflow is low, and the energy consumption is high; 2. The removal of the dust on the filter bag is uneven, which reduces the filter efficiency of the filter bag; 3. Especially The misalignment of the blowing air flow will cause the filter bag to swing due to uneven force, which will easily cause damage to the filter bag and affect the life of the filter bag
