Description

Technical Field

[0001] The invention relates to the technical field of bag dust collectors, and in particular to a bag dust collector and a use method thereof. Background Art

[0002] Bag filter is a dry dust filter, mainly used to capture fine, dry, non-fibrous dust. It uses bag filter elements made of fiber weaving to capture solid particles in dust-laden gas. The working principle of bag filter is based on the filtering principle. When the dust-laden gas enters the bag filter, the large particles and heavy dust settle down and fall into the ash hopper due to gravity.

[0003] The dust bag is the key component of the bag dust collector, usually called the dust bag or dust filter bag. When the gas passes through the dust bag and enters the interior of the dust bag, the particles in the gas will adhere to the surface of the dust bag, and some heavy particles will fall into the ash hopper for discharge. When the humidity in the gas is high, the particles in the gas are easy to adhere to the surface of the dust bag, and as the dust bag works for a long time, the particles on the surface will accumulate more and more, causing the particles to affect the filtering effect of the dust bag.

The gas entering the upper part of the dust collector is discharged through the air outlet pipe. At this time, the particles in the gas will be filtered by the dust bag surface;

[0022] S2: Use the mounting frame to fix the hydraulic rod. When the hydraulic rod pushes the cross to move, the cross will slide on the surface of the stabilizing plate through the contact frame, thereby improving the stability of the cross when moving;

[0023] S3: When the moving plate moves downward, the connection between the spring and the bent plate pushes the circular groove ring downward. When the circular groove ring moves downward, it will get stuck on the surface of the fixed ring. When the moving plate continues to move downward, it will push the groove rod downward. When the groove rod moves, it contacts the spring plate and generates vibration. The vibration is transmitted to the support frame through the fixed ring.

[0024] S4: When the groove rod moves up and down, it pushes the ball to move synchronously through the vertical rod. When the ball moves, it pushes the arc plate to move on the inner wall of the support frame through the elastic rod. When the arc plate moves, it vibrates with the support frame.

[0025] The present invention has the following beneficial effects:

[0026] The dust collector is then blown away by the pressure, and the dust particles in the bag are then passed through the filter bag to be cleaned.

[0027] The present invention provides a mounting frame inside the dust collector, and uses the mounting frame to fix the hydraulic rod. When the hydraulic rod pushes the cross to move, the cross slides on the surface of the stabilizing plate through the contact frame, thereby improving the stability of the cross when moving. When the cross moves, the rectangular frame pushes the dust removal component to move up and down, and the dust removal component is used to clean particles on the surface of the dust bag, thereby preventing particles from adhering to the surface of the dust bag and affecting the working efficiency of the dust bag.

[0028] When the rectangular frame of the present invention moves, it pushes the moving disk to move synchronously through the connecting plate. When the moving disk moves downward, the circular groove ring is pushed downward by the connection between the spring and the bent plate. When the circular groove ring moves downward, it will be stuck on the surface of the fixed ring. When the moving disk continues to move downward, it will push the groove rod to move downward. When the groove rod moves, it will contact the spring plate and vibrate. The vibration is transmitted to the support frame through the fixed ring, and the support frame can clean the particles on the surface of the dust bag through vibration to prevent the particles from adhering to the surface of the dust bag and affecting the filtration efficiency. When the circular groove ring moves upward, the circular groove ring will push the support frame to move upward through the fixed ring, and the support frame will pull the dust bag to produce wrinkles through friction. When the support frame moves downward, the support frame will push the dust bag to straighten, and use the shaking generated when the dust bag is straightened to clean the particles on the surface, thereby further improving the cleaning effect of the dust bag.

[0029] The groove rod of the present invention pushes the ball to move synchronously through the vertical rod when moving up and down. The ball pushes the arc plate to move on the inner wall of the support frame through the elastic rod when moving. The arc plate vibrates with the support frame when moving, and the vibration is transmitted to the lower surface of the dust bag to prevent particles from adhering to the lower surface of the dust bag and affecting the filtering effect.
