[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] Embodiment 1, as Figure 1-3 As shown, a spray device with a filtering device comprises an outer shell 1, a liquid storage tank 11 is arranged inside the outer shell 1, a pressure device and a nozzle are arranged inside the liquid storage tank 11, an outlet 12 is arranged at the front end of the outer shell 1, a handle 13 is arranged at the upper end of the outer shell 1, a disassembly port 14 is arranged at the lower end of the outer shell 1, and the inner structure can be opened for repair or replacement, a filtering device 2 is arranged at the front end of the liquid storage tank 11, three sewage outlets 21 are arranged at the lower end of the filtering device 2, which are used to collect particulate impurities or wastewater cleaned out of different filtering layers, a rotating component 3 is arranged inside the filtering device 2, a pre-filtering group 4 is arranged inside the filtering device 2, a fine filtering group 5 is arranged on the front side of the pre-filtering group 4, an adsorption group 6 is arranged on the front side of the fine filtering group 5, and a biological filtering group 7 is arranged on the front side of the adsorption group 6.

[0020] The liquid storage tank 11 mentioned above is used to store liquid. When pressure is applied to the liquid storage tank 11 through a pressure device, usually an electric pump is used to pressurize the liquid, the liquid in the tank is squeezed under the pressure, and the liquid is transported to the nozzle part through a pipeline. The nozzle generally includes a small nozzle hole or a group of nozzle holes. After the liquid reaches the nozzle, due to the pressure difference, the liquid is sprayed out from the nozzle at a high speed.

[0021] According to Bernoulli's principle, when liquid is sprayed out at high speed, the air around it will be driven by the high-speed flowing liquid, creating a low-pressure area. The surrounding air will quickly replenish this low-pressure area, causing the liquid to be quickly torn into small droplets by the air after leaving the nozzle, thus forming a spray.

[0022] The above is a pressure sprayer in the prior art, which is a conventional technical means, so it will not be elaborated in detail in the present invention.

[0023] Therefore, this solution filters the mist through different filter layers such as the filter device 2, pre-filter group 4, fine filter group 5, adsorption group 6 and biological filter group 7. First, large particles are intercepted to lay a solid foundation for subsequent filtration. Then, the mist is purified by the multi-layer filter paper gradient structure to stably output pure spray. The adsorption layer then captures residual particles to continuously optimize the purity of the mist. Finally, the biological enzyme is promoted to blend with the mist to decompose organic impurities, from preliminary purification to deep treatment. The rotating component 3 is used in conjunction with each filter layer to simultaneously use different cleaning methods for different filter layers to improve the quality of industrial spray and the reliability and stability of the filtration system, meet the diverse needs of industrial production, and reduce the interference of frequent replacement of filter devices on industrial production.

[0024] Embodiment 2: Based on Embodiment 1, this embodiment is for achieving the effect of synchronous cleaning of different filter layers.

[0025] See also Figure 1-13 The rotating assembly 3 includes a motor 31 fixedly connected to the upper end of the outer shell 1, the output end of the motor 31 is fixedly connected to a rotating shaft 1 32, the lower end of the rotating shaft 1 32 is fixedly connected to a bevel gear transmission group 33, and the side of the bevel gear transmission group 33 away from the rotating shaft 1 32 is fixedly connected to a rotating shaft 2 34.

[0026] Specifically, the bevel gear transmission group 33 is composed of two bevel gears meshing with each other, and the rotation direction can be changed.

[0027] See also Figure 3 , Figure 4 and Figure 5 The pre-filter group 4 includes a stainless steel wire mesh 41 arranged on the outer surface of the rotating shaft 2 34, an inner gear ring 42 is fixedly connected to the rear side of the inner surface of the filter device 2, a rotating seat 1 43 is fixedly connected to the outer surface of the rotating shaft 2 34, and connecting seats 44 are fixedly connected to both sides of the rotating seat 1 43.

[0028] Furthermore, the stainless steel wire mesh 41 mentioned above can intercept larger particles in the spray, such as insufficiently atomized droplets and dust particles. This process can quickly remove obvious impurities, allowing the subsequent filter layer to face relatively purer mist, reducing its filtering burden.

[0029] See also Figure 3 and Figure 5 The inner surfaces of the two connecting seats 44 are rotatably connected to a plurality of rotating rods 45, the outer surfaces of the plurality of rotating rods 45 are fixedly connected to a gear 46, the two gears 46 close to the inner surface of the filtering device 2 are meshed and connected with the inner gear ring 42, the front ends of the plurality of rotating rods 45 are fixedly connected to a circular brush 47, and the plurality of circular brushes 47 are rotatably connected to the rear side of the stainless steel wire mesh 41.

[0030] Furthermore, when two gears 46 near the inner surface of the filter device 2 mesh with the inner gear ring 42, several gears 46 will all mesh and rotate, causing the multiple circular brushes 47 to rotate while following the rotation of the connecting seat 44, and continuously rotate to clean the stainless steel wire mesh 41, ensuring that the pores of the wire mesh always remain unobstructed, which helps to maintain the flow stability of the spray through the pre-filtration layer and avoid a drop in flow due to impurity accumulation.

[0031] See also Figure 6-10 The fine filtration group 5 includes a circular ring block 51 fixedly connected to the inner surface of the filter device 2, a connecting plate 52 is fixedly connected to the rear side of the inner surface of the circular ring block 51, a plurality of through grooves 521 are provided on the outer surface of the connecting plate 52, an annular filter membrane 511 is arranged on the inner surface of the circular ring block 51, a filter element central axis 510 is fixedly connected to the inner surface of the annular filter membrane 511, and the annular filter membrane 511 includes cellulose filter paper, polyethersulfone filter paper and polyvinylidene fluoride microporous filter paper.

[0032] Furthermore, the annular filter membrane 511 is composed of multiple layers of filter paper, one layer of filter paper is covered by another layer of filter paper, and from the outside to the inside, the cellulose filter paper, the polyethersulfone filter paper and the polyvinylidene fluoride microporous filter paper are stacked layer by layer to form an annular filter membrane 511 with a certain thickness, which can gradually filter smaller particles in the spray, thereby removing tiny impurities in the mist, including bacteria, viruses, colloidal particles, etc., so that the purity of the mist reaches a higher industrial standard, meeting industrial applications such as precision electronic manufacturing and high-end chemical product spraying that have extremely high requirements for mist quality; The circular ring block 51 is a trapezoid that is narrow in front and wide in the back, so that the cleaning liquid inside can flow along the inner surface of the circular ring block 51 into the sewage outlet 21 located on the rear side of the circular ring block 51. The through groove 521 is located at the edge of the rear end of the circular ring block 51, so that the mist can only enter the interior of the circular ring block 51 from the edge, gradually permeating the annular filter membrane 511 with a certain thickness until it enters the central axis 510 of the filter element and overflows from the hole at the central axis 510 of the filter element. Even if some of the mist does not pass through each layer of filter paper evenly, it still needs to pass through the thicker annular filter membrane 511, which can also achieve a better filtering effect.

[0033] Furthermore, the front end of the filter element central axis 510 is hollow, and the rear end is sealed, so that when the mist passes from the rear end to the front end, it cannot flow directly through the filter element central axis 510, and needs to be filtered layer by layer in the annular filter membrane 511 before entering the filter element central axis 510 and being discharged from its front end.

[0034] See also Figure 2 , Figure 6-9 The outer surface of the rotating shaft 34 is fixedly connected with a rotating cylinder 53, and a plurality of one-way valves 54 are arranged in an annular array on the upper side of the outer surface of the rotating cylinder 53. The inner surface of the filtering device 2 is fixedly connected with a fixing rod 542, and a rotating seat 541 is fixedly connected to the middle position of the fixing rod 542. The inner surface of the rotating seat 541 is rotatably connected to the rotating shaft 34, and a water pipe 543 is fixedly connected to the upper end of the rotating seat 541, and a water storage tank 544 is fixedly connected to the upper end of the water pipe 543.

[0035] Furthermore, the interior of the rotating drum 53 can transport cleaning liquid through the water tank 544, the water pipe 543 and the fixed rod 1 542, and transport the cleaning liquid to the interior of the rotating shaft 2 34 through the hole. The hole on the rotating shaft 2 34 is located inside the rotating seat 2 541. Then the cleaning liquid flows from the rotating shaft 2 34 and flows out from the hole opened at the other end. The hole on the rotating shaft 2 34 is located inside the rotating drum 53, and finally the rotating drum 53 is filled with cleaning liquid.

[0036] When the rotating drum 53 rotates, the centrifugal force makes the water pressure enough to push open the one-way valve 54, and the water spills out from the one-way valve 54, causing the cleaning liquid to flow from the inside of the annular filter membrane 511 to the outer surface, washing away the impurities attached to the outer surface of the annular filter membrane 511 and the inside of the micropores. In addition, due to the centrifugal force, the spilled water will first contact the filter element center axis 510, and then flow out from the filter holes on the surface of the filter element center axis 510, which will reduce most of the impact force and avoid the problem of excessive pressure damaging the filter paper structure. When the rotating drum 53 stops rotating, the water pressure disappears, and the one-way valve 54 is closed under the action of its own elasticity to prevent water from flowing out.

[0037] See also Figure 8 The outer surface of the rotating shaft 2 34 is fixedly connected to a connecting frame 55 on the front side of the connecting plate 52, the outer surface of the rotating shaft 2 34 is fixedly connected to a gear 2 56 on the front side of the connecting frame 55, the left and right sides of the gear 2 56 are meshed with gear 3 57, the rear sides of the two gear 3 57 are fixedly connected to the rotating shaft 3 58, the two rotating shafts 3 58 are rotatably connected to the connecting frame 55, the front ends of the two gear 3 57 are fixedly connected to a fan 59, and the diameter ratio of the gear 2 56 to the gear 3 57 is one to two.

[0038] Furthermore, the connecting frame 55 can drive the two gears three 57, the rotating shaft three 58 and the fan 59 to revolve around the rotating shaft two 34. During the revolution, the gear three 57 will mesh with the gear two 56, and the diameters of the two are different. The rotation speed of the gear three 57 is twice that of the gear two 56, driving the two fans 59 to rotate at a high speed to generate wind force, thereby quickly taking away moisture, preventing the filter paper from breeding microorganisms and reducing the filtering performance due to long-term moisture, and ensuring that the filter paper always maintains a good working condition during the long-term industrial spray filtration process.

[0039] See also Fig.11 and Fig.12 The adsorption group 6 includes a fixed seat 61 fixedly connected to the inner surface of the filter device 2, a plurality of springs 62 are fixedly connected to the rear side of the fixed seat 61, and a metal fiber sintered felt mesh 63 is fixedly connected to the rear ends of the plurality of springs 62. The inner surface of the metal fiber sintered felt mesh 63 is movably connected to the rotating shaft 2 34, and five fixed rods 2 64 are fixedly connected to the front side of the metal fiber sintered felt mesh 63. The front ends of the five fixed rods 2 64 are all rotatably connected to pulleys 65. A rotating disk 66 is fixedly connected to the outer surface of the rotating shaft 2 34 and located in front of the pulley 65. Five trapezoidal holders 67 are fixedly connected to the rear side of the rotating disk 66, and the five pulleys 65 are slidably connected to the five trapezoidal holders 67.

[0040] Furthermore, the material of the metal fiber sintered felt mesh 63 has good moisture resistance and can maintain stability in structure and performance in a humid environment.

[0041] When the rotating shaft 2 34 is rotating, the rotating disk 66 rotates along with the rotating shaft 2 34. One side of the trapezoidal holder 67 is an inclined surface and the other side is a right angle. When the trapezoidal holder 67 rotates along with the pulley 65, its inclined surface will first contact the pulley 65, causing the pulley 65 to continuously slide and disengage on the trapezoidal holder 67, causing the fixed rod 2 64 to be continuously stretched and retracted, thereby driving the metal fiber sintered felt mesh 63 to continuously vibrate, shaking off the particles adsorbed on the surface of the metal fiber sintered felt mesh 63, so that the adsorption layer can continue to work effectively, avoiding blockage of the adsorption layer and reduction of filtration efficiency due to particle accumulation, ensuring that the mist can always be stably purified when passing through the adsorption layer, and reducing the system downtime and maintenance costs caused by adsorption layer failure.

[0042] See also Fig.13 The biological filtration group 7 includes a biological enzyme catalytic filling box 71 fixedly connected to the outer surface of the rotating shaft 2 34, a filter screen 1 711 is arranged at the rear end of the biological enzyme catalytic filling box 71, a filter screen 2 712 is arranged at the front end of the biological enzyme catalytic filling box 71, and a stirring rod 72 is fixedly connected to the outer surface of the rotating shaft 2 34 and located inside the biological enzyme catalytic filling box 71.

[0043] Furthermore, after the mist spray enters the bio-enzyme catalytic filling box 71, the internal stirring rod 72 allows the liquid components in the mist to fully contact with the bio-enzyme. The bio-enzyme can specifically decompose the organic impurities in the mist and convert the organic pollutants, oils, proteins, etc. that may remain in the industrial production process into harmless small molecules.

[0044] A pulley transmission group 73 is symmetrically arranged at the front end of the rotating shaft 2 34, and the ends of the two pulley transmission groups 73 away from the rotating shaft 2 34 are fixedly connected with a bidirectional screw rod 74, the rear ends of the two bidirectional screw rods 74 are rotatably connected to the front end of the bio-enzyme catalytic filling box 71, and the outer surfaces of the two bidirectional screw rods 74 are rotatably connected to the extrusion plate 75, the front end of the bio-enzyme catalytic filling box 71 is fixedly connected to two limit rods 76, the inner surfaces of the two extrusion plates 75 are rotatably connected to the two limit rods 76, the front end of the bio-enzyme catalytic filling box 71 is fixedly connected to two annular air bags 77, the front ends of the two annular air bags 77 are fixedly connected to the rear ends of the two extrusion plates 75, the outer surfaces of the two annular air bags 77 are provided with a one-way valve 2 78, and the outer surfaces of the two annular air bags 77 are provided with a one-way valve 3 79.

[0045] Furthermore, the pulley transmission group 73 mentioned above is composed of two pulleys of different diameters and a belt, so that the rotation speed of the bidirectional screw 74 is less than the rotation speed of the rotating shaft 34. When the bidirectional screw 74 rotates, it can drive the extrusion plate 75 to move back and forth, thereby driving the two annular air bags 77 to continuously expand and compress, and the two annular air bags 77 have opposite functions. One absorbs moisture inside the bio-enzyme catalytic filling box 71 and discharges it to the outside, and the other absorbs fresh air from the outside and then sprays it out of the bio-enzyme catalytic filling box 71. This humidity and air conditioning mechanism creates a suitable working environment for the bio-enzyme, ensuring that the activity of the bio-enzyme can be maintained during the long process of spray filtration. Appropriate humidity and sufficient oxygen supply help the bio-enzyme to efficiently decompose organic impurities, thereby improving the purification ability of the entire filtration system for organic components in the mist spray.

[0046] Working principle: After the spray is sprayed out through the pressure device inside the liquid storage tank 11, the spray will first pass through the stainless steel wire mesh 41 to intercept larger particles in the mist, such as droplets and dust particles that are not fully atomized, and then enter the annular filter membrane 511 through the through groove 521, and gradually filter through the cellulose filter paper, polyethersulfone filter paper and polyvinylidene fluoride microporous filter paper layer by layer, pass through the filter element center axis 510 and overflow from the front end of the filter element center axis 510, pass through the metal fiber sintered felt mesh 63, the metal fiber sintered felt mesh 63 adsorbs and intercepts those tiny particles that still remain in the mist, such as trace metal ions, organic small molecules that have not been completely filtered, etc., and then enter the bio-enzyme catalytic filling box 71 through the filter screen 1 711, and use the bio-enzyme to decompose the organic impurities in the mist, such as organic pollutants, oils, proteins, etc. that may remain in the industrial production process, and convert them into harmless small molecules. Finally, it overflows from the filter screen 2 712 and is sprayed out from the outlet 12.

[0047] When the filter device 2 needs to be cleaned as a whole, the motor 31 is first started to drive the rotating shaft 1 32, the bevel gear transmission group 33 and the rotating shaft 2 34 to rotate, and the rotating shaft 2 34 drives the rotating seat 1 43, the connecting seat 44 and the gear 1 46 to rotate, so that the gear 1 46 and the inner gear ring 42 are meshed, thereby driving a plurality of gears 1 46 to rotate, so that the plurality of circular brushes 47 rotate themselves while the whole rotates, and the stainless steel wire mesh 41 is fully cleaned, and the cleaned impurities will fall into the sewage outlet 21 at the rear side; Secondly, when the rotating shaft 2 34 rotates, it will drive the connecting frame 55 to rotate. The connecting frame 55 can drive the two gears 3 57, the rotating shaft 3 58 and the fan 59 to revolve around the rotating shaft 2 34. During the revolution, the gear 3 57 will mesh with the gear 2 56. The diameters of the two gears are different. The rotation speed of the gear 3 57 is twice that of the gear 2 56, which drives the two fans 59 to rotate at a high speed to generate wind force, thereby quickly taking away the moisture on the annular filter membrane 511, and at the same time turning on the water pump inside the water storage tank 544. The cleaning liquid inside is transported to the rotating drum 53 through the water pipe 543, the second rotating seat 541 and the second rotating shaft 34. At this time, the rotating drum 53 is driven by the second rotating shaft 34 to rotate. The cleaning liquid inside will push the one-way valve 1 54 open due to the centrifugal force. The cleaning liquid will pass through the central axis 510 of the filter element to the outside and clean the annular filter membrane 511 from the inside to the outside. The cleaning liquid that passes through the annular filter membrane 511 will flow to the rear side along the shape of the circular ring block 51 and be discharged from the sewage outlet 21 located in the middle position. Next, when the second rotating shaft 34 is rotating, the rotating disk 66 will rotate along with the second rotating shaft 34. The trapezoidal holder 67 is in the shape of a right-angled trapezoid, with one side being an inclined surface and the other side being a right angle. When the trapezoidal holder 67 rotates along with the pulley 65, the inclined surface will first contact the pulley 65, so that the pulley 65 is squeezed and the metal fiber sintered felt mesh 63 is driven to retreat. When the pulley 65 is separated from the trapezoidal holder 67, the metal fiber sintered felt mesh 63 will be brought back due to the elastic force of the spring 62. Therefore, the pulley 65 continuously slides and separates on the trapezoidal holder 67, so that the second fixing rod 64 is continuously stretched and retracted, thereby driving the metal fiber sintered felt mesh 63 to continuously shake and shake off the particles adsorbed on the surface of the metal fiber sintered felt mesh 63. Finally, when the rotating shaft 2 34 rotates, the stirring rod 72 is driven to rotate to stir the bio-enzyme particles, and the rotating shaft 2 34 drives the two pulley transmission groups 73 to rotate, so that the two bidirectional screw rods 74 rotate synchronously, but the initial states of the two extrusion plates 75 and the annular airbags 77 are different. One annular airbag 77 is in a state of being squeezed by the extrusion plate 75. At this time, the movement of the extrusion plate 75 toward the front end will drive the annular airbag 77 to expand, and the one-way valve 3 79 on this side can only take in air but not discharge air, and the one-way valve 2 78 can only discharge air but not discharge air. The annular airbag 77 on this side can absorb the moisture in the bio-enzyme catalytic filling box 71 and discharge it through the one-way valve 2 78, while the extrusion plate 75 on the other side moves toward the rear end to drive the annular airbag 77 to be squeezed, and the one-way valve 3 79 on this side can only let out air but not let in air, and the one-way valve 2 78 can only let in air but not let out air, so the annular airbag 77 on this side will suck in the fresh air from the outside through the one-way valve 2 78 and discharge it into the bio-enzyme catalytic filling box 71 through the one-way valve 3 79, creating a suitable working environment for the bio-enzyme.

[0048] As long as the water pump in the water storage tank 544 is not started to input cleaning liquid into the rotating cylinder 53, the above device can work together with the normal spray state.

[0049] Therefore, this solution performs multi-layer filtration on the spray through the stainless steel wire mesh 41, the annular filter membrane 511, the metal fiber sintered felt mesh 63 and the bio-enzyme catalytic filling box 71 inside the filter device 2, and respectively provides a circular brush 47 for cleaning the stainless steel wire mesh 41, a rotating cylinder 53 for backwashing the annular filter membrane 511, a shaking of the metal fiber sintered felt mesh 63, and an annular airbag 77 for air replacement of the bio-enzyme catalytic filling box 71 for different filter layers to prevent clogging of the filter layer, ensure smooth flow of the spray, extend the service life of each filter layer, continuously optimize the purity of the spray, and stably output pure spray.
