Abstract
Description
Technical Field
[0001] The invention relates to the technical field of bag dust collectors for asphalt stations, and in particular to a bag dust collector for asphalt stations. Background Art
[0002] Asphalt mixing plant, also known as asphalt concrete mixing plant, refers to a complete set of equipment used for mass production of asphalt concrete. It can produce asphalt mixture, modified asphalt mixture, and colored asphalt mixture. It is necessary equipment for the construction of highways, grade highways, municipal roads, airports, and ports. Asphalt concrete needs to heat and mix the raw materials during the production process, and a large amount of dust will be generated during the production process. The bags in the bag dust collector effectively adhere to the dust generated during the production of asphalt concrete to prevent dust from entering the air and polluting the environment. Large particles of dust in dust-containing gas need to be recycled, so large particles of dust and fine dust need to be collected separately. The general practice is to add a primary dust collector in front of the bag dust collector to collect large particles of dust. The dusty gas first enters the primary dust collector, where large dust particles are removed before entering the dust removal box of the bag dust collector. There are many bags in the box, and the gas passes through the bags from the dust removal box into the clean gas box. The dust cannot pass through the bags and is blocked outside the bags. When the dust on the bags accumulates to a certain extent, the backflush pipe blows out compressed air to blow the dust off the surface of the bags and drop it into the dust collection bucket. The clean air that has filtered out the dust is discharged from the air outlet.
[0003] The existing bag dust collector for asphalt stations uses an externally installed separately arranged primary dust collector to collect dust and fine dust separately. However, this method requires the primary dust collector to be arranged separately, and the bag dust collectors need to be connected by pipes, which leads to a large footprint of the device, and the pipes have wind resistance, which increases energy consumption. Therefore, it is urgent to design a bag dust collector for asphalt stations to solve the above problems. Summary of the invention
[0004] The object of the present invention is to provide a bag dust collector for asphalt plants to solve the problem proposed in the above background technology that the existing bag dust collector for asphalt plants uses an externally added separately arranged primary dust collector to collect dust and fine dust separately, but this method requires the primary dust collector to be arranged separately, and the bag dust collectors need to be connected by pipes, resulting in a large footprint of the device, wind resistance in the pipes, and increased energy consumption.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a bag dust collector for an asphalt station, comprising: a dust removal box, a dust removal structure is arranged at the front end of the dust removal box, the dust removal structure includes a sedimentation chamber, the sedimentation chamber is arranged at the front end of the dust removal box, an air inlet is arranged on the right side of the sedimentation chamber, a bag body is arranged inside the dust removal box, the bag body is evenly arranged inside the dust removal box, a clean air box body is arranged at the upper end of the dust removal box, and an air outlet is fixedly arranged at the left end of the clean air box body.
[0006] Preferably, guide plates are provided on the sedimentation chamber, the guide plates are inclined, and the guide plates are evenly distributed inside the sedimentation chamber.
[0007] Preferably, a backflush pipe is provided on the bag body.
[0008] 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.
[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] 1. The bag dust collector of the asphalt station is equipped with a dust removal structure. A space is reserved at the air inlet of the bag dust collector of the asphalt station as a settling chamber. It replaces the primary dust collector and uses the settling chamber to separate large dust particles from small dust particles. There are multiple sets of guide plates inside the settling chamber. After the dust-containing gas enters from the air inlet, it hits the guide plate, and the large dust particles are ejected and change the direction of movement, falling down and being collected. The gas containing small particles enters the dust removal box. There are many bag bodies in the dust removal box. The gas passes through the bag body from the dust removal box and enters the clean air box. The dust cannot pass through the bag body and is blocked outside the bag body. When the dust on the bag body accumulates When it reaches a certain level, the backblowing pipe blows out compressed air to blow the dust on the surface of the bag body off, causing it to fall and be collected. The clean air that has filtered out the dust is discharged from the air outlet, and the coarse powder collection bucket is used to collect large particles of dust. The fine powder collection bucket is used to collect the dust blown off the surface of the bag body by the backblowing pipe. The bag dust collector for the asphalt station can utilize the settling chamber and the guide plate arranged inside it to replace the primary dust collector, avoiding the need for the existing asphalt station bag dust collector to be arranged separately with the primary dust collector, and the bag dust collectors need to be connected by pipes, which occupies a large area, and the pipes have wind resistance, which increases energy consumption, thereby improving the practicability and efficiency of the device.
