Through setting up of keeping off the edge, can make the opening edge leakproofness of filter bag better, and the installation is very easy, only need establish the sack cover on keeping off the edge, then through keeping off the edge and the joint structure joint between the protection barrel inner wall link to each other.
In the bag filter, a cylindrical permanent magnet strip is embedded in the sealing part, and the sealing ring is made of iron material.
The arrangement of the permanent magnet strip can ensure the reliability of the following two working processes: 1. when the air flow is very small and the rotating drum cannot be driven to rotate, the rotating drum can be closed to prevent air leakage through the arrangement of the permanent magnet strips; 2. when the air flow is large and the impact force is enough to drive the rotary drum to rotate, the rotary drum rotates in a 'pause' rotating state due to the arrangement of the permanent magnet strips, so that the time that the dust accumulation opening penetrates through the inner cavity of the protective barrel and the outside is shortened as much as possible, and unfiltered air flow is effectively prevented from being discharged.
In the bag type dust collector, when one permanent magnetic strip is adsorbed on one side of the sealing ring, the other permanent magnetic strip symmetrically distributed with the one permanent magnetic strip can be adsorbed on the other side of the sealing ring, and sealing is realized between the inner side surface of the sealing ring and the peripheral surface of the rotary drum.
In the above-mentioned bag filter, the drum is made of elastic rubber material.
The rotary drum is made of rubber materials, and rubber expands and deforms under the action of the adsorption force of the permanent magnetic strips, so that the tightness between the outer wall of the rotary drum and the sealing ring is better.
In the bag type dust collector, the lower end of the clamping arm is detachably connected with the frame through bolts.
The clamp arm is detachably connected to the frame through bolts, so that the rotary drum is convenient to disassemble and assemble and high in stability.
In the bag type dust collector, the sealing ring is detachably connected with the wall of the protection barrel through bolts.
In the bag type dust collector, the frame is provided with a dust storage groove positioned below the rotary drum.
