[0001] The invention belongs to the field of air purification, and in particular relates to an air purification device. Background Art

[0002] The sources of polluted air are complex, and the current technical methods for air pollution treatment need to be improved. If air pollution is not properly treated, it will also cause water pollution. The more common technical problems currently encountered are the following: gas with sticky and wet types, dry, sticky and wet mixed types, chemical types, chemicals mixed with dry, sticky and wet, and also various dry, sticky, wet, fishy, ​​odorous, fungal mixtures, etc.

[0003] Existing technical methods include: bag dust removal, water curtain dust removal, activated carbon, activated cotton adsorption, ultraviolet sterilization and deodorization, plasma method, etc. The shortcomings of existing equipment and technology are as follows: the functionality of the technology is relatively single, and it cannot handle slightly mixed polluted air sources, or can only barely handle them, and it is difficult to achieve long-term standard emissions; due to insufficient technology, the cost of equipment use and operation is high, and users have large investments, low benefits, high consumption, and high maintenance costs. Some technical equipment requires regular replacement of consumables, so users cannot afford it or use it well.

There are two kinds of power during rotation, one is the pressure of the wind itself, and the other is the rotation of the dirt suction plate to drive the airflow to rotate. During rotation, because the weight of the pollutants is greater than the weight of the air, they will be thrown to the barrel wall by centrifugal force; part of the pollutants in the air are adsorbed on the surface of the dirt suction plate during the contact between the air and the dirt suction plate;

At this time, the wind speed in the air duct is significantly slowed down due to large-area diffusion. During the slowing down, rotation, and rolling of the moving speed of the polluted air, the pollutants continuously hit the surface of the dirt suction plate between the upper and lower parts;

[0017] The upper end of the rotating shaft is fixedly connected to the upper end wall plate through a conical cylinder connecting piece, and the lower end is fixedly connected to the lower end wall plate through a lower end wall plate connecting piece.

[0022] Furthermore, the base mounting plate is evenly distributed with a plurality of fan-shaped through holes, with ribs of sufficient strength left between the holes as supporting ribs. The function of the fan-shaped through holes is to allow impurities separated from the air in the main barrel to fall into the sewage storage and drainage system below through the fan-shaped through holes. A downwardly protruding circular drip extension plate is provided on the outer circle of the base mounting plate to facilitate the delay of sewage dripping only downwards and not extending to the middle to affect the components connecting the driving motor and the main shaft, thereby increasing the strength of the components.

[0023] The upper end of the fan-shaped hole is connected to the main cylinder, and the lower end is connected to the large mouth of the conical cylinder. An electric valve is arranged at the lower end of the conical cylinder. When the separation system is working, the electric valve is closed, pollutants can fall in, and air cannot pass through. When the cleaning system is working, the electric valve is opened.

[0024] Specifically, the induced draft system includes an induced draft duct and an induced draft fan arranged on the induced draft duct. The induced draft duct is tangent to the side of the main barrel body at the air inlet, and the external air is tangentially passed into the main barrel body through the induced draft fan. The air inlet is preferably a flat air inlet to facilitate the rapid diffusion of air entering the main barrel body; the air inlet is set with positive pressure, and the air outlet is negative pressure. Suction power can also be set at the air outlet.

[0031] Preferably, the suction plate is a metal plate or a plastic plate, and grooves are provided on the upper and lower surfaces. The side walls of the grooves can effectively avoid air resistance in a rotating state. Due to the action of the rotating centrifugal force, the reverse movement of the substance is generated, and the pollutants in the air are sucked into the groove through the surface wall and separated, and then gathered on the inner wall of the main barrel body; preferably, the suction plate is made of PV plastic plate, and the electrostatic effect of the particles is utilized to adsorb and gather on the suction plate; a spacer ring is provided between the two adjacent suction plates above and below, and the spacer ring is installed on the through shaft.

[0032] Beneficial effects:

[0033] 1. In the separation system of the device of the present invention, air enters the main cylinder through the flat diffusion air inlet and rotates in the forward direction. There are two kinds of power, one is the wind pressure carried by itself, and the other is the mechanical rotation driving the airflow rotation force. At this time, because the weight of the pollutants is greater than the weight of the air, the pollutants are centrifugally thrown to the cylinder wall, that is, the initial physical separation occurs, and the coarse substances in the air are separated; the air is dispersed into each thin air duct after large-area diffusion, so the wind speed entering the air duct is significantly slowed down, and it will rotate in the rotating air duct, and it will also produce continuous tumbling, disrupting the phenomenon of the air carrying substances in a straight line. Therefore, the pollutants are continuously thrown to the upper and lower walls and the grooves of the suction plate, and secondary or even multiple physical separations occur. Due to the action of the rotating centrifugal force, the accumulation falling into the groove will produce a reverse motion with the air and be thrown to the cylinder wall. The clean air after separation enters the negative pressure space in the middle, and can only be gathered to the upper opening for discharge because the bottom is closed.

[0034] 2. The device of the present invention uses an infusion pump to input the prepared cleaning agent into the center of the main shaft through the small holes on the circular surface and spray it into the thin air duct, so as to clean the accumulation in the dirt suction plate and the groove at a fixed time. As long as the actual cleaning time required by the material is mastered, the electronic control program can be set to automatically complete it. Regular cleaning is also equivalent to regularly spraying humidity and viscosity into the air duct, which increases the dirt suction capacity in the air duct.

[0035] 3. The device of the present invention can significantly reduce the PM2.5 value in the air. By combining physical methods with mechanical structures, it can remove various substances in the polluted air, especially various dry, wet, oily, sticky, chemical, and extremely difficult to handle mixed pollutants. There is no need to replace objects regularly, and the service life is long. The use and operation costs are low. After separation, the polluted air can reach the clean air required by the human body. According to the pollution source parameters of different environments, a variety of models and specifications are set. As long as the user selects the appropriate specifications, the management and protection of the air environment in different areas can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] The air purification device of the present invention is mainly used in industry to efficiently separate gases and impurities in the air, that is, to separate impurities such as humidity, oil, chemicals, including fungi, dust and garbage in the air to obtain relatively clean air. The working method of the whole process includes: the air enters the air inlet 102 diffused between the upper and lower parts through the pressure of the fan, and rotates clockwise in the main barrel body 101. There are two kinds of power to generate rotation, one is the wind force itself, and the other is the mechanical rotation driving the airflow to rotate. At this time, due to gravity, in the centrifugal rotation state, a physical phenomenon of impurities separation in the air occurs, and a large amount of impurities are thrown out and adsorbed on the inner wall of the main barrel body 101; then the air is dispersed into the thin air duct formed between the dirt suction plates 105. Because the cumulative height of countless thin air duct openings is greater than 1:3 times the diameter of the air duct 201, the air entering the air duct expands the space area. The wind speed is significantly slowed down. At the same time, due to the rotation of the dirt suction plate 105, the air entering the thin air duct also rotates and is in a constant tumbling state. The impurities carried by the air will constantly hit the upper and lower walls of the dirt suction plate 105, especially the grooves 140 opened on the surface of the dirt suction plate; the function of the grooves 140 is to reduce and avoid wind resistance in the rotating state, especially the side walls of the grooves have a more obvious wind-proof effect. The accumulation falling into the grooves can produce reverse motion with the air due to the strange thrust caused by centrifugal force. At this time, when the air passes through the thin air duct, a second or even multiple material separation phenomenon actually occurs.

[0080] After the separated clean air enters the hollow position in the middle, the lower end wall panel connector 123 is closed, and the conical cylinder connector 122 is open, so that the air enters from the side and converges upward in the barrel space. The present invention can also be designed with a timed automatic cleaning function, and different cleaning times and intervals can be set according to different pollution sources. The cleaning agent can also increase the dirt absorption capacity in the air duct. The infusion pump 502 delivers the cleaning agent into the rotating shaft 103 through the infusion tube 503. The circumference of the rotating shaft 103 is evenly distributed with small Hole 135 is sprayed into the thin ventilation duct when the rotating shaft 103 is rotating. Under the action of the rotating centrifugal force, the accumulation in the ventilation duct and the accumulation on the inner wall of the main barrel body 101 are regularly sprayed and cleaned, and enter the conical barrel body 301 through the base mounting plate, pass through the electric valve 302, and the cleaned objects enter the dirt storage barrel 402 for sedimentation. The floating liquid overflows through the filter screen 404 to the overflow bucket 401 for further sedimentation, and the floating liquid enters the cleaning agent solution barrel 501 through the overflow pipe 405 for storage, and is circulated through the infusion pump 502.

The above is only a preferred embodiment of the present invention.
