Description

Technical Field

[0001] This utility model relates to the field of air purification equipment technology, specifically to an air dust adsorption and treatment device. Background Technology

[0002] Dust hazards are a hot topic of concern in today's society. Dust consists of solid suspended particles with a diameter of less than 75μm. Inhalation can harm human health, and a certain concentration of dust in a confined space can even cause an explosion. Examples include indoor spray painting environments, the spread of pollution sources in medical rooms, dusty loading and unloading environments in warehouses, sand casting environments in foundry workshops, and the spread of pollutants from indoor smokeless combustion.

[0003] Existing airborne dust separation devices generally use filters to filter large particles and adsorbents to adsorb small particulate matter and toxic gases. However, after a period of use, the filters accumulate a large amount of dust and particles, reducing the filtration efficiency of the gas and affecting gas flow. Furthermore, the adsorbent needs to be replaced manually, which is complicated and limits the efficiency of the equipment. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an airborne dust adsorption and treatment device.

[0005] The technical solution of this utility model is as follows: an air dust adsorption treatment device, including a shell, a filter assembly disposed at the lower end of the shell, an adsorption assembly disposed inside the shell and above the filter assembly, and an exhaust fan disposed at the top of the shell; an air inlet groove is provided through the lower end of the outer wall of the shell, and an air guide hood is provided on the outer wall of the shell at a position corresponding to the position of the air inlet groove.

[0006] The filter assembly includes two mounting plates disposed inside the housing and located at the upper and lower ends of the air inlet slot, and a filter screen sleeve disposed between the two mounting plates; a guide hole is provided at the center of the mounting plate located inside the housing.

[0007] The adsorption assembly includes a barrier mesh disk disposed inside the housing and above the flow guide hole, and activated carbon adsorbent filled inside the housing and above the barrier mesh disk.

[0008] Furthermore, a movable pressure plate is slidably engaged at the top of the housing, and several vent holes are provided through the movable pressure plate; a guide rod is provided at the top of the housing, which passes through the movable pressure plate, and a compression spring is sleeved on the guide rod and abuts against the upper end face of the movable pressure plate;

[0009] Explanation: The movable pressure plate slides downward along the guide rod under the compression of the clamping spring, so that the activated carbon adsorbent filled inside the shell is always in a compacted state, which is beneficial to improving the adsorption effect of the activated carbon adsorbent on fine dust in the air.

[0010] Furthermore, the movable pressure plate is provided with a pull-out tube that penetrates the shell, and a sealing plug is movably snapped into the top of the pull-out tube; a cover plate is movably hinged on the outer wall of the shell at the position corresponding to the activated carbon adsorbent.

[0011] Instructions: When it is necessary to replace the activated carbon adsorbent inside the shell, open the cover, remove the used activated carbon adsorbent, and then use the pull tube to pull the movable pressure plate upward along the guide rod. The activated carbon adsorbent is then filled into the shell through the cavity of the pull tube, which improves the ease of use of the device.

[0012] Furthermore, there are several filter screen sleeves, each of which is nested together, and the mesh diameter of each filter screen sleeve decreases sequentially from the outside to the inside.

[0013] Note: By setting up multiple filter screens, the device's ability to block airborne dust particles is improved, and the device's reliability is also enhanced.

[0014] Furthermore, each filter screen is movably fitted with a cleaning ring, and a lifting plate is slidably engaged with the bottom of the housing via a column; a return spring is fitted on the column and abuts against the bottom surface of the lifting plate; an operating plate is provided on the lifting plate, penetrating the housing and slidably engaged with the housing; ash-collecting arc grooves are provided on the mounting plate located at the bottom of the housing and corresponding to the positions of each cleaning ring; a pull rod is provided on the lifting plate, penetrating the corresponding ash-collecting arc grooves and connecting to each cleaning ring; a sealing seat is fitted on each pull rod and engages with the bottom surface of the corresponding ash-collecting arc groove; a dust removal hole is provided at the lower end of the outer wall of the housing;

[0015] Instructions: Pull the lifting plate downwards along the column using the control panel. During the movement of the lifting plate, pull the cleaning ring to move outside the corresponding filter screen sleeve via the pull rod to clean the dust blocked outside the filter screen sleeve. At the same time, during the movement of the pull rod, the sealing seat disengages from the dust collection arc groove, allowing the cleaned dust to enter the bottom of the housing for collection.

[0016] Furthermore, an air distribution coil is provided inside the shell and below the barrier mesh. The air distribution coil is connected to the guide hole, and several air distribution holes are distributed equidistantly on the upper end face of the air distribution coil.

[0017] Note: By setting up a uniform air distribution coil, it is beneficial to improve the uniformity of air diffusion inside the activated carbon adsorbent and increase the utilization rate of the activated carbon adsorbent.

[0018] The working principle of this utility model is as follows:

[0019] When in use, turn on the exhaust fan. Outside air enters the housing through the air inlet slot under the action of the air guide hood. After being filtered by each filter screen in sequence, the outside air enters the upper part of the housing through the guide holes on the mounting plate. When the outside air passes through the activated carbon adsorbent, the fine pollutant particles in the air are adsorbed and removed by the activated carbon adsorbent. The purified air is discharged through the top of the housing under the action of the exhaust fan. When it is necessary to clean the filter screen, pull the lifting plate down along the column by operating the control panel. During the movement of the lifting plate, pull the cleaning ring to move outside the corresponding filter screen by pulling the rod to clean the dust blocked outside the filter screen. At the same time, during the movement of the rod, the sealing seat disengages from the dust collection arc groove, allowing the cleaned dust to enter the bottom of the housing for collection. When it is necessary to replace the activated carbon adsorbent, open the cover plate, remove the used activated carbon adsorbent, and then use the pull tube to pull the movable pressure plate up along the guide rod, and fill the housing with activated carbon adsorbent through the cavity of the pull tube.

[0020] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects:

[0021] First, the structure of this utility model is reasonably designed. By filtering and adsorbing polluted air, it improves the separation effect of floating dust in polluted air. Compared with a single floating dust separation method, it has the advantages of high separation efficiency and stable and reliable operation.

[0022] Secondly, by attaching a cleaning ring to the outside of the filter screen sleeve, this utility model can regularly clean the filter screen sleeve, effectively extending the service life of the filter screen sleeve and improving the working efficiency of the device.

[0023] Third, by setting a movable pressure plate inside the shell, the activated carbon adsorbent is always compressed and filled under the action of the movable pressure plate, which is beneficial to improving the adsorption effect of the activated carbon adsorbent on fine dust in the air.
