Description

Technical Field

[0001] The present invention relates to the technical field of bag filters with a conveying particle structure, and specifically to a bag filter with a conveying particle structure. Background Art

[0002] During the production of asphalt concrete, the raw materials need to be heated and stirred, and a large amount of dust will be generated during the production process. Large-particle dust is collected by a primary dust collector, and fine dust is collected by a bag filter to prevent dust from entering the air and polluting the environment. The large-particle dust in the dust-containing gas needs to be recycled, so it is necessary to collect the large-particle dust and fine dust separately. Generally, a primary dust collector is added in front of the bag filter to collect the large-particle dust. The dust-containing gas first enters the primary dust collector, and after the large-particle dust is removed by the primary dust collector, it enters the subsequent process through a screw conveyor and is transported to the mixing plant for recycling. The fine powder enters the bag filter with the wind, is filtered in the bag filter, enters the powder collection hopper at the bottom of the dust collector, and is transported and discharged by a screw conveyor.

[0003] During the use of the existing bag filter, sometimes the particle size of the raw materials in the mixing plant is large, and a part of fine powder needs to be added to adjust the gradation and fill the gaps between the aggregates. At this time, a part of the fine powder collected in the dust collector needs to be added to the mixing plant as part of the raw materials. The existing equipment usually adopts the scheme of a screw conveyor and a bucket elevator to lift the fine powder discharged from the dust collector into the mixing tank. The required equipment is numerous and the process is complex. Therefore, it is urgent to design a bag filter with a conveying particle structure to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a bag filter with a conveying particle structure to solve the problem that during the use of the existing bag filter, sometimes the particle size of the raw materials in the mixing plant is large, and a part of fine powder needs to be added to adjust the gradation and fill the gaps between the aggregates. At this time, a part of the fine powder collected in the dust collector needs to be added to the mixing plant as part of the raw materials. The existing equipment usually adopts the scheme of a screw conveyor and a bucket elevator to lift the fine powder discharged from the dust collector into the mixing tank, and the required equipment is numerous and the process is complex.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A bag filter with a conveying particle structure, comprising: a dust removal box, a conveying particle structure is arranged at the front of the dust removal box, the conveying particle structure includes a sedimentation chamber, the sedimentation chamber is arranged at the front of the dust removal box, an air inlet is arranged on the right side of the sedimentation chamber, a bag is arranged inside the dust removal box, the bags are evenly arranged inside the dust removal box, an anti-blowing pipe is arranged at the upper end of the bag, a clean air box body is arranged at the upper end of the dust removal box, and an air outlet is arranged on the left side of the clean air box body.

[0006] Preferably, the settling chamber is provided with a coarse powder collecting hopper, and the dust removal box is provided with a fine powder collecting hopper.

[0007] Preferably, a long auger is provided inside the dust removal box, and the long auger is arranged inside the sedimentation chamber.

[0008] Preferably, the long auger conveying end is connected with a fine powder discharge port, the fine powder discharge port is connected with a fine powder external discharge auger, the long auger conveying end is connected with a coarse powder discharge port, the coarse powder discharge port is connected with a coarse powder external discharge auger, and the fine powder external discharge auger is connected with the output end of the frequency conversion motor.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The bag dust collector with a particle conveying structure is equipped with a particle conveying structure. A settling chamber is added to the front of the dust box as a first-level dust removal to collect large particles of dust. A settling chamber is added to the front of the dust box. The dust box and the settling chamber share a long auger to convey the fine powder filtered by the bag and the large particles of dust falling from the settling chamber. The fine powder external discharge auger is driven by a variable frequency motor to dynamically adjust the speed of the fine powder external discharge auger. When it is not necessary to add fine powder, the speed of the fine powder external discharge auger is increased, the fine powder external discharge auger conveying capacity is increased, and all fine powder slips away from the fine powder discharge port. When it is necessary to add a portion of fine powder into the mixing tank, the speed of the fine powder external discharge auger is reduced, and the fine powder that cannot be discharged in time accumulates in the dust collector subdivision collection bucket and fills the fine powder discharge port. Driven by the long auger, the fine powder enters the coarse powder collection bucket and enters the coarse powder external discharge auger through the coarse powder discharge port, and enters the next process together with the coarse powder. Through this design, the bag dust collector with a particle conveying structure can control the amount of fine powder added according to the speed of the fine powder external discharge auger, avoiding the existing equipment usually using the auger plus bucket elevator solution, and lifting the fine powder discharged from the dust collector into the mixing tank, avoiding the problems of multiple equipment and complex processes, and improving the practicability and convenience of the device.

Through this design, a sedimentation chamber 211 is added to the front of the dust removal box 111, and the dust removal box 111 and the sedimentation chamber 211 share a long auger 218 to convey the fine powder filtered by the cloth bag 213 and the large particle dust falling from the sedimentation chamber 211.

[0018] Furthermore, the conveying end of the long auger 218 is connected with a fine powder discharge port 219, which is connected to a fine powder external discharge auger 220, and the conveying end of the long auger 218 is connected with a coarse powder discharge port 222, which is connected to a coarse powder external discharge auger 223, and the fine powder external discharge auger 220 is connected to the output end of the variable frequency motor. Through this design, the fine powder external discharge auger 220 is driven by a variable frequency motor, and the speed of the fine powder external discharge auger 220 is dynamically adjusted. When it is not necessary to add fine powder, the speed of the fine powder external discharge auger 220 is accelerated, the conveying amount of the fine powder external discharge auger 220 is increased, and all the fine powder slips away from the fine powder discharge port 219.
