Description

Technical Field

[0001] This utility model relates to the field of air purification equipment technology, and in particular to an air particulate matter purification and treatment device for concrete and asphalt mixing plants. Background Technology

[0002] Air particulate matter purification equipment is designed to effectively remove dust and particulate matter from the air, improving air quality. It is widely used in industrial plants, concrete and asphalt mixing plants, and dust pollution control facilities. Concrete and asphalt mixing plants generate large amounts of dust and particulate matter during production. If left untreated, this not only affects air quality but can also cause equipment malfunctions and environmental pollution.

[0003] However, traditional air particulate matter purification equipment requires manual cleaning by users after a period of use, which is cumbersome, has high maintenance costs, and is usually a single-stage filter, which cannot effectively remove dust of different particle sizes in stages, easily leading to rapid clogging of the filter.

[0004] Therefore, those skilled in the art have provided an air particulate matter purification and treatment device for concrete and asphalt mixing plants to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an air particulate matter purification device for concrete and asphalt mixing plants. This device is equipped with a coarse filtration mechanism and a fine filtration mechanism. Under the detection of a laser dust concentration sensor, the controller can automatically start an appropriate number of fans according to a preset time, thereby ensuring a balance between treatment effect and energy consumption, improving efficiency, and enabling particulate matter to be intercepted and filtered by an iron filter screen and multiple limiting filters. The combination of coarse and fine filtration gradually removes particles of different sizes, improving filtration accuracy and equipment lifespan, reducing the frequency of filter clogging, and the included lever can move a fixed plate under the drive of a servo motor. A return spring causes the fixed plate to collide with a rubber buffer pad, causing particles accumulated on the iron filter screen to fall into the collection box under gravity. The collision and gravity automatically remove the accumulated particles, reducing the burden of manual maintenance.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

Under the detection and identification of the laser dust concentration sensor 10, the controller 11 automatically controls the appropriate number of fans 3012 to start according to the preset range value. The servo motor 202 rotates at low speed, thereby controlling the toggle block 204 to push open the fixing plate 208. When the toggle block 204 is separated from the fixing plate 208, under the pull of the return spring 206, the fixing plate 208 collides with the rubber buffer pad 207, thereby shaking the particles accumulated on the iron filter screen 209 into the collection box 8. Water is placed in the collection box 8 to reduce the possibility of particles flying around.
