Description

Technical Field

[0001] The invention relates to the technical field of bag dust collectors, in particular to a pulse bag dust collector mechanism. Background Art

[0002] The pulse bag dust collector consists of an ash hopper, an upper box, a middle box, and a lower box. The upper, middle, and lower boxes are chamber structures. When working, dust-laden gas enters the ash hopper from the air inlet, coarse dust particles fall directly into the bottom of the ash hopper, and fine dust particles enter the middle and lower boxes upward with the turning of the air flow. Dust accumulates on the outer surface of the filter bag, and the filtered gas enters the upper box to the clean air collection pipe-exhaust duct, and is discharged to the atmosphere through the exhaust fan. The cleaning process is to first cut off the clean air outlet duct of the room, so that the bag of the room is in a state where there is no airflow (separate chamber air is stopped for cleaning). Then open the pulse valve and use compressed air for pulse spraying and cleaning. The closing time of the cut-off valve is sufficient to ensure that the dust peeled off from the filter bag after spraying settles to the ash hopper, avoiding the phenomenon that the dust is attached to the surface of the adjacent filter bag with the air flow after leaving the surface of the filter bag, so that the filter bag is cleaned thoroughly.

[0003] The cleaning method of the filter bag in the prior art is to expand the bag by back-blowing to eject the dust covered on the outside. This process easily leads to incomplete cleaning of the dust on the outer surface of the bag or poor cleaning efficiency. In addition, dust is easily attached to the inner wall of the bag dust collector, which is inconvenient to clean. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a pulse bag dust collector mechanism to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. Large particles of impurities in the air containing dust are blocked by a flat screen plate to prevent them from entering the bag and causing blockage. Under the action of the driving assembly, the bottom plate and the flat screen plate are merged and move up and down along the inside of the machine body. The two flapping plates are driven to hit the two side surfaces of the bag through the connection between the plug block and the connecting block. The dust on the outer surface of the bag is cleaned by flapping, thereby improving the efficiency of the subsequent self-cleaning of dust on the bag by the machine body, and at the same time, the inner wall of the machine body is cleaned.

The bottom plates are opposite to the bottom of the plane screen plate and plug blocks are arranged on both sides of the bottom plates. Connecting blocks are arranged at the bottom of both sides of the plane screen plate and the plug blocks can be slidably inserted into the inside of the connecting blocks. The plane screen plate is pushed up and down by the bottom plates.

[0006] Furthermore, a pulse controller is installed on the outer wall of the body at the air inlet, a compressed gas storage bag is installed on the top of the pulse controller, an air duct is provided on the top of the mounting plate inside the body, and an electromagnetic valve is installed at one end of the air duct inside the body passing through the body, and the pulse valve of the pulse controller and the electromagnetic valve are connected to the air duct.

[0007] Furthermore, blowing holes are equidistantly arranged on the surface of the air duct inside the body, and the positions of the blowing holes correspond to the top of the connecting pipe.

[0008] Furthermore, the driving assembly also includes a sliding frame, which is connected to the two sides of the two base plates, and the upper and lower parts of the sliding frame are hollowed out, a bidirectional screw is rotatably installed in the sliding frame through a bearing, a motor is fixed to the outer end of the sliding frame, and the output end of the motor is fixedly connected to the bidirectional screw, and moving blocks are threadedly sleeved on both ends of the bidirectional screw, and the moving block is fixedly connected to the plug block.

[0009] Furthermore, movable grooves are provided on both sides of the bottom of the flat screen plate, the connecting block slides inside the movable grooves, a slot is provided at the bottom of the connecting block, the top of the insert block is a T-shaped structure, and the inside of the slot is a T-shaped slot.

[0010] Furthermore, a slapping plate is provided on one side of the planar screen plate facing the middle plate, and a connecting rod is fixed between the connecting block and the slapping plate.

[0011] Furthermore, a convex strip is fixed on the surface of the bottom plate at a position corresponding to the sieve slot of the plane sieve plate, and the convex strip can be slidably inserted into the sieve slot.

[0012] Furthermore, four groups of first electric push rods are fixed at positions on the bottom of the body corresponding to the bottom plate, and the extended ends of the first electric push rods are fixedly connected to the bottom plate.

[0013] Furthermore, a scraper is provided on the side of the body parallel to the top of the bottom plate, and the scraper is in contact with the inner wall of the body. A second electric push rod is fixed on the outer wall of the body, and the extended end of the second electric push rod is fixedly connected to the scraper.

[0014] Furthermore, a spring is fixed to the top inner wall of the slide groove, and the other end of the spring is fixedly connected to the slide block.

[0015] Beneficial effects of the present invention:

[0016] 1. After the bottom plate of the present invention is docked with the flat screen plate, the flat screen plate can be pulled to the bottom of the middle plate by the plug-in block and the connecting block. At this time, the scraper is located on the top of the flat screen plate, and the scraper is driven by the second electric push rod to move along the surface of the flat screen plate, and the dust on the scraper is pushed out from the middle gap, and then the dust is concentrated and sent out from the dust outlet to reduce the floating of dust.

[0017] 2. In the air intake stage of the present invention, the bottom plate and the flat screen plate are separated, and the flat screen plate is kept parallel to the middle plate by the spring force. Before the equipment self-cleans the cloth bag, the first electric push rod drives the bottom plate to move up, and the plug block is plugged into the connecting block. At the same time, the convex strip on the bottom plate is inserted into the sieve slot, and the flat screen plate forms a complete flat plate. Then, in the process of the flat screen plate being pushed up and down by the bottom plate, the inner wall of the machine body is scraped and cleaned, and the fallen dust will also fall on the surface of the flat screen plate, which is convenient for uniformly cleaning and sending out the dust on the inner wall. The movement of the flat screen plate slides along the slide groove of the inner wall of the machine body and is limited by the spring force. It remains in the position between the bottom of the cloth bag device and the air inlet without the push of the bottom plate.

[0018] 3. The present invention can realize the vertical clamping of the insertion block and the connecting block after the bidirectional screw is slightly moved left and right. When the plane screen plate moves to the surface of the cloth bag, the bidirectional screw is driven to rotate by the motor, and the two moving blocks cooperate with the bidirectional screw to slide along the sliding frame, driving the connecting block to slide along the moving groove, and the connecting rod pushes the slap plate to move out of the outside of the plane screen plate toward the cloth bag. The movement process is controlled to reciprocate by the motor, so that the two slap plates reciprocate and hit the two sides of the cloth bag to knock off the dust accumulated on it, thereby improving the efficiency of subsequent self-cleaning.

[0019] 4. Compared with the prior art, the present invention uses a flat screen plate to block large particles of impurities in the dust-containing air to prevent them from entering the bag and causing blockage. Under the action of the driving assembly, the bottom plate and the flat screen plate are combined and move up and down along the inside of the machine body. The two flapping plates are driven to hit the two side surfaces of the bag through the connection between the plug block and the connecting block. The dust on the outer surface of the bag is cleaned by flapping, thereby improving the efficiency of the subsequent self-cleaning of dust on the bag by the machine body, and at the same time cleaning the inner wall of the machine body.
