DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0038] The present invention relates to an air filtration device used in the construction of a sterile environment, such as Figure 1 and Figure 2 As shown, it includes a first adsorption box 1, a second adsorption box 2, an electrostatic adsorption component 3 and a partition 4. The specific structure of each component is as follows:

[0039] The first adsorption box 1 is independently fixed, and an air guide pipe 11 and an air inlet pipe 12 communicating with the interior of the first adsorption box 1 are respectively installed on the top and bottom. An aeration assembly 13 is arranged at the bottom of the first adsorption box 1, and the first adsorption box 1 is filled with water;

[0040] The second adsorption box 2 is fixedly installed above the first adsorption box 1. The bottom of the second adsorption box 2 is connected to the first adsorption box 1 through the air guide pipe 11. The top of the second adsorption box 2 is equipped with an air outlet pipe 21 connected to the inside of the second adsorption box 2.

[0041] The electrostatic adsorption components 3 are arranged in two groups and are symmetrically installed on the left and right sides of the second adsorption box 2;

[0042] The partition plates 4 are provided in plurality and are installed in a staggered manner in the second adsorption box 2 and are located between the two electrostatic adsorption components 3;

[0043] The working principle of the air filtration equipment is mainly divided into two stages: a pretreatment stage and a deep purification stage; in the pretreatment stage, air enters the first adsorption box 1 from the air inlet pipe 12, and the aeration component 13 fully mixes the air with water, and uses the physical properties of water to capture larger particles, dust and some soluble pollutants, which can effectively remove large particle impurities and reduce the burden of subsequent purification. The air that has been preliminarily purified enters the second adsorption box 2 from the first adsorption box 1 through the air guide pipe 11; in the deep purification stage, after the air enters the second adsorption box 2, it first passes through the staggered partitions 4. These partitions 4 increase the flow path of the air, so that the air is more evenly distributed inside the second adsorption box 2, thereby improving the subsequent purification effect. The electrostatic adsorption component 3 is used to generate an electrostatic field to attract and capture fine particles, bacteria, viruses and other particles in the air. The electrostatic adsorption technology can efficiently remove submicron particles and is a key step in achieving high-cleanliness air. The deeply purified air is finally discharged from the outlet pipe 21 into a sterile environment.

[0044] Specifically, Figure 3 As shown, each electrostatic adsorption component 3 includes:

[0045] Adsorption ring 31, adsorption ring 31 is composed of a plurality of jigsaw plates 32;

[0046] The center rod 33 is rotatably mounted inside the second adsorption box 2 and driven by a driving motor;

[0047] The annular plate 34 is sleeved on the outside of the central rod 33 and fixedly connected to the central rod 33 via a connecting rod 35;

[0048] The movable column 36 is provided in plurality, one end of which is slidably connected to the annular plate 34 and the other end of which is fixedly connected to the puzzle plate 32;

[0049] The first spring sheet is provided in plurality, and both ends thereof are fixedly connected to the annular plate 34 and the movable column 36 respectively;

[0050] The knocking structure 38 is in transmission connection with the center rod 33. When the center rod 33 rotates, the knocking structure 38 knocks the puzzle boards 32 in sequence.

[0051] The working principle of the electrostatic adsorption component 3 designed in this equipment is as follows: the driving motor drives the central rod 33 to rotate, thereby driving the entire adsorption ring 31 to rotate, attracting particles with opposite charges, and realizing the adsorption of dust, microorganisms, etc. in the air; as the central rod 33 rotates, the knocking structure 38 can periodically knock the puzzle board 32, causing the adsorbed particles to fall off, thereby realizing the self-cleaning function; the annular plate 34 enables the puzzle board 32 to be displaced to a certain extent under the action of the knocking structure 38, and the first spring piece is used to maintain the elastic connection between the moving column 36 and the annular plate 34, which helps to restore the position of the puzzle board 32; self-cleaning reduces the need for manual maintenance and maintains the efficient operation of the electrostatic adsorption component 3; because the adsorption ring 31 can rotate, a dynamic adsorption process is formed, which helps to improve the capture rate of tiny particles in the air.

[0052] The knocking structure 38 can be realized by existing technologies such as electromagnets and spring reset mechanisms, but these existing technologies can only realize simple knocking functions, while in this device, it is necessary to quickly respond and realize accurate knocking of each puzzle board 32 one by one. In order to solve the above problems, this device designs a better knocking structure 38, such as Figure 4 As shown, including:

[0053] The bevel gear 381 is fixedly mounted on the outer side of the center rod 33;

[0054] The helical gear column 382 is vertically arranged and meshes with the helical gear 381;

[0055] The column 383 is fixedly mounted on the bottom of the helical tooth column 382. A slide groove 384 is provided on the outer side of the circumference of the column 383. A slider 385 is slidably connected in the slide groove 384.

[0056] The knocking rod 386 is vertically arranged and fixedly connected to the slider 385;

[0057] The second spring piece 387 has two ends fixedly connected to the knocking rod 386 and the second adsorption box 2 respectively;

[0058] The working process and principle of the knocking structure 38 are as follows: the center rod 33 is driven by a driving motor and rotates around its own axis. The bevel gear 381 rotates with the rotation of the center rod 33. The bevel gear column 382 meshing with the bevel gear 381 will rotate and move up and down along the axis under the drive of the bevel gear 381, thereby driving the column 383 fixed at the bottom of the bevel gear column 382 to move together; the slider 385 slides in the slide groove 384 of the column 383, driving the knocking rod 386 to move up and down; when the knocking rod 386 moves downward, it knocks on the puzzle board 32 of the electrostatic adsorption component to remove dust and particles on it; the second spring piece 387 is stretched when the knocking rod 386 moves downward to store elastic potential energy; when the knocking rod 386 moves upward, the second spring piece releases the elastic potential energy to help the knocking rod reset and prepare for the next knock.

[0059] In order to collect the knocked-off impurities, Figure 1 and Figure 3 As shown, the electrostatic adsorption component 3 also includes a collection structure 39, and the collection structure 39 includes:

[0060] There are two collecting boxes 391, which are respectively installed directly below the adsorption ring 31. The top of the collecting box 391 is provided with a dust outlet connected to the second adsorption box 2, and the bottom of the collecting box 391 is provided with a dust outlet;

[0061] The cover 392 is movably mounted on the bottom of the collection box 391 and corresponds to the dust outlet;

[0062] When the knocking rod 386 of the knocking structure 38 knocks the puzzle board 32 of the electrostatic adsorption component, the dust and particulate matter on the puzzle board 32 are shaken off and fall into the collection box 391 below through the dust outlet and accumulate in the collection box 391; the design of the cover 392 makes the cleaning of the collection box 391 simple and convenient, reducing maintenance time and cost. When the impurities in the collection box 391 accumulate to a certain amount, the cover 392 is opened to discharge the impurities from the dust outlet; after the dust removal is completed, the cover 392 is closed again to restore the sealing state of the collection box 391; by setting the collection box 391 directly below the adsorption ring 31, it is ensured that the knocked-off impurities can fall into the collection box 391 quickly and directly to avoid secondary flying; the cover 392 remains closed in the non-dust removal state to ensure that the impurities in the collection box 391 will not leak out, keeping the working environment clean.

[0063] like Figure 3 and Figure 4 As shown, each panel 32 is composed of an adsorption plate and an electrode plate on the back, and two arc plates 22 are symmetrically installed in the second adsorption box 2, and multiple conductive wheels 23 are installed on the outside of each arc plate 22, and the outer wall of each conductive wheel 23 is in contact with the electrode plate;

[0064] The conductive wheel 23 is used to transfer electric charge to the electrode plate in contact with it. The local electric field design helps to reduce unnecessary power loss and improve the energy efficiency of the system. By generating charges only on one side of the gas flow direction, the electric field interference in other areas is reduced, unnecessary adsorption is avoided, and the knocking structure 38 is ensured to effectively shake off impurities. The conductive wheel 23 can rotate with the rotation of the electrode plate, thereby reducing static friction with the electrode plate, reducing wear and extending the service life of the components. The conductive wheel 23 is made of elastic material, and the part in contact with the electrode plate undergoes elastic deformation, thereby ensuring continuous and close contact and avoiding electric field instability problems caused by poor contact.

[0065] In order to ensure that the adsorption ring 31 after adsorbing impurities can rotate smoothly without contacting the inner wall of the second adsorption box 2, a gap is left between the adsorption ring 31 and the second adsorption box 2 to reduce the flow of air through the gap and ensure that the air flows along the correct route, such as Figure 3 As shown, an air guide plate 41 is provided at one end of the partition plate 4 close to the adsorption ring 31;

[0066] The air guide plate 41 is used to guide the direction of the air flow. When the air flows in the second adsorption box 2, the air guide plate 41 guides the air flow to the opposite direction when the air flow flows to the position of the air guide plate 41, so that the air flow flows between the partitions 4 arranged in an alternating manner up and down according to the planned path, thereby reducing the chance of flowing through the gaps.

[0067] To further enhance the water adsorption effect, Figure 3 As shown, a toggle member is further provided inside the first adsorption box 1, and the toggle member includes a rotating rod 14 and a plurality of paddles 15 connected to the rotating rod 14, and a channel for gas to pass through is opened on the paddle 15. A water inlet pipe 16 and a water outlet pipe 17 connected to the interior of the first adsorption box 1 are installed on the first adsorption box 1, and the paddle 15 is driven to rotate by the water entering the first adsorption box 1 through the water inlet pipe 16;

[0068] Through the toggle piece, water enters the first adsorption box 1 through the water inlet pipe 16, and the water flow impacts the surface of the paddle 15, causing the paddle 15 to rotate. The rotating paddle 15 guides the airflow to form a vortex in the first adsorption box 1, thereby increasing the contact time between the airflow and water, improving the water washing effect, and effectively removing large particles and some microorganisms; the vortex makes the airflow more evenly distributed in the first adsorption box 1, avoiding poor cleaning effect caused by local uneven airflow; the water is continuously stirred by the rotating paddle 15, thereby reducing the precipitation of large particles in the water and avoiding blockage inside the first adsorption box 1.

[0069] Furthermore, if Figure 3 As shown, a water pump 18 is provided on the water outlet pipe 17, and a plurality of nozzles 19 connected to the water outlet pipe 17 are installed inside the first adsorption box 1. The nozzles 19 are vertically arranged and penetrate the partition 4. Each nozzle 19 is provided with a plurality of nozzles 191, and the nozzles 191 are arranged on the leeward side of the nozzle 19;

[0070] The water pump 18 is used to pump out the water in the first adsorption box 1 and transport it to the nozzle 19 through the water outlet pipe 17. The water is sprayed into the airflow through the nozzle 191, further increasing the adsorption opportunity. A filter is provided in the water outlet pipe 17 to filter impurities in the water to ensure the cleanness of the transported water. By arranging the nozzle 191 on the leeward side of the nozzle 19, the airflow velocity is prevented from being slowed down due to the direct impact of the water flow on the airflow.

[0071] To optimize the distribution of airflow, such as Figure 3 and Figure 5 As shown, the nozzle 19 is in the shape of a rhombus;

[0072] The principle of this structure is to utilize the guiding effect of the diamond-shaped edge on the airflow so that the airflow can flow more evenly to the nozzle 191 position of the adjacent nozzle 19, thereby achieving better effect; at the same time, the diamond-shaped edge can reduce the resistance of the airflow when passing through, thereby avoiding slowing down the airflow velocity.

[0073] To further increase the air flow rate, Figure 5 As shown, the shape of the nozzle 191 is an arc-shaped opening;

[0074] This structure utilizes the Venturi effect, that is, when the fluid enters a wider area from a narrow area, the flow rate will increase and the pressure will decrease. This design helps to increase the outflow velocity of the nozzle 191 and accelerate the airflow.

[0075] The air filtering equipment used in the construction of a sterile environment of the present invention can be installed, connected or set up in a common mechanical manner, and any method that can achieve its beneficial effects can be implemented.

[0076] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
