A method and device for adaptive control of electromagnetic pulse air valves of road sweepers. When the pressure value of the gas tank reaches the set pressure, the method sequentially controls the first pulse air valve and the second pulse air valve in each group of pulse air valves to blow air according to the first set time and the second set time, respectively, to complete the first round of air blowing control; when the pressure value of the gas tank reaches the set pressure, the method sequentially controls the second pulse air valve and the first pulse air valve in each group of pulse air valves to blow air according to the second set time and the first set time, respectively, to complete the second round of air blowing control; the first round of air blowing control and the second round of air blowing control are used as a blowing control cycle for cycle control to achieve adaptive control of pulse air valves. The present invention uses the method of cross-patrol of pulse air valves to consume gas from the gas tank to achieve balanced dust removal after multiple pulse air valves have completed a cycle, thereby avoiding local severe pollution of dust removal filters and filter clogging.

The utility model relates to waste cutting equipment technical field, and disclose a kind of waste cutting equipment for preparing environment-friendly building material, by being equipped with knife rest, spray nozzle, pre-wetting frame, cleaning frame and other structures, realize uniform dust fall, material is continuously conveyed through pre-wetting frame, through the multidirectional spray of diffusion nozzle, the surface of material is preliminarily pre-wetted, subsequently material is located below pneumatic cylinder, start pneumatic cylinder, cut by knife rest and cutting edge to material, since material is pre-wetted by spray of pre-wetting frame before being cut, make less dust overflow when cutting, water is sprayed by dust fall nozzle when cutting, play the dust fall of cutting edge cooling and cutting, when just appearing, be wetted by water, avoid flying in air, subsequently output roller belt carries on the continuous conveying to material, when conveying through cleaning frame position, lateral nozzle is washed to the surface of material from two directions, remaining adhering dust and chippings are washed away, play the effect of uniform dust fall.

The utility model provides a surface dust removal device for corrugated paper processing, which belongs to the technical field of corrugated paper processing, and comprises a fixed base, the top of the fixed base is provided with a conveying component, and the surface dust removal device for corrugated paper processing is characterized in that the fixed base is placed on the surface of the corrugated paper to be dedusted; at the moment, the conveying assembly can be directly used for carrying out large-range uniform dust removal on a dust removal brush in the conveying assembly in a circular track within the coverage range of the conveying assembly, and a single brush does not need to be used for cleaning in a small range, so that the overall dust removal effect and range of the device are further improved; in this way, the overall working efficiency of a user is improved, dust generated by dust removal can be swept into the dust storage assembly along with the conveying track of the conveying assembly to be stored, and the user can also detach the dust storage assembly at any time according to the structural characteristics of the dust storage assembly to conduct centralized dust cleaning. And the overall functionality and the dust removal effect of the device are further improved.

The present application relates to a kind of IGBT cleaning device, including rack, top open box is equipped on the rack, box is matched with the cover plate that is turned over in the open at open, the upper surface or lower surface of cover plate is equipped with cover plate groove, cover plate is equipped with retractable locking mechanism on the position corresponding to the opposite side of cover plate groove;Box is equipped with first horizontal moving platform, first horizontal moving platform is installed with the air knife or plasma torch that moves horizontally by first horizontal moving platform, the nozzle of air knife or plasma torch is towards cover plate and is spaced apart with cover plate between interval distance that avoids cover plate overturning;The inner bottom surface of box is equipped with dust extraction mechanism;Rack is also equipped with material conveying mechanism by first motor driving and parallel with box.The present application realizes the cleaning of automation, improves the cleaning effect and cleaning efficiency, and reduces cost.

The utility model provides a motor coil insulation powder coating device, which relates to the technical field of powder coating devices and comprises a frame, and struts are symmetrically and fixedly mounted at the bottom of the frame. According to the powder spraying device, by arranging the rotating disc and other structures, a motor coil needing powder spraying is placed between the limiting disc and the first disc, then the rotating disc is rotated, the rotating disc drives the threaded rod to rotate in the second disc, and the threaded rod can drive the limiting disc to slide on the outer wall of the connecting column in the rotating process; after the motor coil slides for a certain distance, the limiting disc is matched with the first disc to clamp and fix the motor coil, the motor is started after fixing, the motor drives the shaft rod to rotate, the shaft rod drives the clamped and fixed motor coil to turn over in the rotating process, and the structure can automatically turn over the motor coil, so that the motor coil is prevented from being damaged. Therefore, the motor coil can be uniformly sprayed with powder, the situation that the motor coil needs to be turned over manually during powder spraying is effectively avoided, and the powder spraying efficiency of the motor coil is improved.
