Detailed implementation manners

[0022] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0023] The following describes in detail the specific implementation of the present invention in combination with specific embodiments.

[0024] Such as Figure 1 、 Figure 2 、 Figure 3As shown in the figure, it is a structural diagram of an environmental protection air purification and filtration device provided by an embodiment of the present invention, including a cylinder body 1. Two sets of the cylinder bodies 1 are provided and connected to form a V-shaped structure. A support plate 2 is fixedly installed on the bottom wall of the cylinder body 1. The top end of one set of the cylinder bodies 1 is set as an air inlet 11, and the top end of the other set of the cylinder bodies 1 is set as an air outlet 12. The air inlet 11 is connected to an external air extraction device. A bottom cylinder 3 is fixedly installed at the bottom ends of the two sets of the cylinder bodies 1. The bottom cylinder 3 is communicated with the cylinder body 1. A column 5 extending into the water storage tank 4 is rotatably installed in the bottom cylinder 3. The bottom end of the column 5 extends below the bottom cylinder 3 and is connected to a motor 51. A plurality of sets of filter plates 6 distributed in parallel are arranged in the inner cavity of the cylinder body 1. A central shaft 7 is rotatably installed at the axis position of the inner cavity of the cylinder body 1 through a bracket. The central shaft 7 passes through the center of the filter plate 6. A humidifying mechanism 10 is arranged in the cylinder body 1. The humidifying mechanism 10 includes a spraying component 101 and a driving component 102. The spraying component 101 is located in the cylinder body 1 and is connected to the water storage tank 4. The driving component 102 is located in the water storage tank 4. The driving component 102 atomizes and humidifies the inner cavity of the cylinder body 1 by cooperating with the spraying component 101. A dust removal mechanism 8 cooperating with the filter plate 6 is arranged in the inner cavity of the cylinder body 1. The dust removal mechanism 8 includes a cleaning component 81 and a guiding and discharging component 82. The cleaning component 81 is located on the surface of the central shaft 7 and outside the filter plate 6. When the column 5 rotates, the cleaning component 81 controls the central shaft 7 to rotate synchronously and further cleans the surface of the filter plate 6. The guiding and discharging component 82 is connected to the bottom cylinder 3. The guiding and discharging component 82 is used to discharge the impurities cleaned from the surface of the filter plate 6 outside the cylinder body 1 and the bottom cylinder 3. A positioning mechanism 9 cooperating with the filter plate 6 is arranged in the cylinder body 1. The positioning mechanism 9 includes a limiting component 91 and a telescopic component 92. The limiting component 91 is located on the inner side wall of the cylinder body 1 and is connected to the filter plate 6. The limiting component 91 is used to support and position the filter plate 6 in the inner cavity of the cylinder body 1. The telescopic component 92 is located on the surface of the central shaft 7 and is connected to the filter plate 6. When the central shaft 7 rotates, the telescopic component 92 controls the filter plate 6 to reciprocate along the axis direction of the cylinder body 1 by cooperating with the limiting component 91.

[0025] During use, the exhaust device conveys air into the cylinder body 1. When the air flows in the inner cavities of the two groups of cylinder bodies 1, it will pass through the meshes on the surfaces of the multiple groups of filter mesh plates 6. The filter mesh plates 6 can filter the dust and impurities in the air, and the dust and impurities will adhere to the surfaces of the filter mesh plates 6. When filtering the air, the motor 51 drives the column 5 to rotate, and the driving component 102 and the spraying component 101 cooperate with each other to automatically perform atomizing humidification treatment on the inner cavity of the cylinder body 1. After humidifying the air in the inner cavity of the cylinder body 1, the filtering effect of the filter mesh plates 6 on dust and impurities can be further improved. While humidifying the inner cavity of the cylinder body 1, the cleaning component 81 controls the central shaft 7 to rotate in the inner cavity of the cylinder body 1, and further can clean the impurities adhering to the surfaces of the filter mesh plates 6. The drainage component 82 can transfer the humidified dust and impurities cleaned from the surfaces of the filter mesh plates 6 to the bottom cylinder 3. After the dust and impurities in the bottom cylinder 3 accumulate to a certain extent, the drainage component 82 can conveniently take out the dust and impurities from the bottom cylinder 3. While the cleaning component 81 is cleaning the dust and impurities adhering to the surfaces of the filter mesh plates 6, the telescopic component 92 and the limiting component 91 cooperate with each other to control the filter mesh plates 6 to reciprocate slightly along the axial direction of the cylinder body 1. When the filter mesh plates 6 reciprocate, the cleaning component 81 can fully clean the dust and impurities stuffed in the meshes of the filter mesh plates 6, further improving the cleaning effect on the filter mesh plates 6.

[0026] As Figure 1 , Figure 2 , Figure 3 shown, as a preferred embodiment of the present invention, the spraying component 101 includes a spraying pipe 1011 fixedly installed on the inner top wall of the cylinder body 1. Multiple groups of atomizing nozzles are arranged on the surface of the spraying pipe 1011. Notches matching with the spraying pipe 1011 are formed on the surfaces of the filter mesh plates 6. Water filling cylinders 1012 are respectively fixedly installed on the opposite two side walls of the water storage tank 4. A water guide pipe 1013 is fixedly installed at the end of the water filling cylinder 1012 away from the water storage tank 4. The end of the water guide pipe 1013 away from the water filling cylinder 1012 extends into the cylinder body 1 and is connected to the spraying pipe 1011.

[0027] An appropriate amount of cleaning water is stored in the inner cavity of the water storage tank 4. The motor 51 drives the column 5 to rotate, and the driving component 102 sends an appropriate amount of water pressure in the water storage tank 4 into the water filling cylinder 1012. The water filling cylinder 1012 and the water guide pipe 1013 cooperate with each other to further convey the water to the spraying pipe 1011 at high pressure. The spraying pipe 1011 uniformly sprays the water in an atomized state into the inner cavity of the cylinder body 1. The atomized water fully contacts the dust and impurities in the air, and the filter mesh plates 6 can perform efficient filtering treatment on the dust and impurities.

[0028] As Figure 1 , Figure 2 , Figure 6 , Figure 7As shown, as a preferred embodiment of the present invention, the driving assembly 102 includes a cross column 1021 slidably installed horizontally in the inner cavity of the water storage tank 4. A long strip-shaped guide groove 1022 is formed on the bottom wall of the cross column 1021. A control disk 1023 located below the cross column 1021 is fixedly installed at the top end of the column 5. A guide post 1024 extending into the guide groove 1022 is arranged at a position deviating from the center of the surface of the control disk 1023. Connecting rods 1025 are respectively fixedly installed on the opposite side walls of the cross column 1021. A piston disk 1026 cooperating with the water filling cylinder 1012 is fixedly installed at one end of the connecting rod 1025 away from the cross column 1021.

[0029] During use, the motor 51 drives the column 5 to rotate, thereby driving the control disk 1023 to rotate in the water storage tank 4. The control disk 1023 drives the guide post 1024 to rotate synchronously. The guide post 1024 and the guide groove 1022 cooperate with each other to control the reciprocating movement of the cross column 1021 in the inner cavity of the water storage tank 4. The cross column 1021 and the connecting rod 1025 cooperate with each other to drive the piston disk 1026 to move synchronously. When the piston disk 1026 moves towards the water filling cylinder 1012 and further inserts into the water filling cylinder 1012, the piston disk 1026 can send the water pressure in the water filling cylinder 1012 into the water guide pipe 1013.

[0030] As Figure 2 、 Figure 3 、 Figure 4 As shown, as a preferred embodiment of the present invention, the cleaning assembly 81 includes a cleaning rod 811 fixedly installed on the surface of the central shaft 7 and located outside the filter screen plate 6. Multiple groups of brush hairs 812 attached to the surface of the filter screen plate 6 are arranged on the surface of the cleaning rod 811. A driven bevel gear disk 813 is fixedly installed at the bottom end of the central shaft 7. A driving bevel gear disk 814 meshingly connected with the driven bevel gear disk 813 is fixedly installed on the surface of the column 5.

[0031] During use, the motor 51 drives the column 5 to rotate, thereby driving the driving bevel gear disk 814 to rotate. The driving bevel gear disk 814 and the driven bevel gear disk 813 are in meshing transmission to drive the central shaft 7 to rotate in the inner cavity of the cylinder body 1. The central shaft 7 drives the cleaning rod 811 to rotate, and the cleaning rod 811 drives the brush hairs 812 to rotate outside the filter screen plate 6. The brush hairs 812 can automatically clean the dust and impurities attached to the surface of the filter screen plate 6.

[0032] As Figure 1 、 Figure 2 、 Figure 3 As shown, as a preferred embodiment of the present invention, the guiding and discharging assembly 82 includes a guiding and discharging port 821 formed on the bottom wall of the filter screen plate 6. A guiding and discharging pipe 822 is arranged on the side wall of the bottom cylinder 3. A control valve 823 is arranged on the surface of the guiding and discharging pipe 822.

[0033] After the brush 812 removes the dust and impurities attached to the surface of the filter screen plate 6, the dust and impurities fall onto the inner bottom wall of the cylinder body 1. The dust and impurities pass through the discharge port 821 at the bottom of the filter screen plate 6, further slide downward, and finally fall into the bottom cylinder 3. After the dust and impurities in the bottom cylinder 3 accumulate to a certain extent, the discharge pipe 822 is opened, and the dust and impurities can be conveniently discharged from the bottom cylinder 3.

[0034] As Figure 2 , Figure 3 , Figure 5 As shown in, as a preferred embodiment of the present invention, the limiting component 91 includes a plurality of groups of annularly distributed sliding grooves 911 formed on the inner side wall of the cylinder body 1. A sliding block 912 is slidably installed in the sliding groove 911, and a compression spring 913 connected to the sliding block 912 is fixedly installed in the sliding groove 911. The plurality of sliding blocks 912 are connected to the filter screen plate 6.

[0035] During use, the plurality of sliding blocks 912 cooperate with each other to support and position the filter screen plate 6 in the inner cavity of the cylinder body 1. When the telescopic component 92 applies a thrust to the filter screen plate 6, the sliding block 912 slides in the sliding groove 911. The telescopic component 92 and the compression spring 913 cooperate with each other to control the small-amplitude reciprocating movement of the filter screen plate 6 in the inner cavity of the cylinder body 1. When the filter screen plate 6 reciprocates, the brush 812 can be inserted into the mesh holes on the surface of the filter screen plate 6, which can further improve the cleaning effect of the brush 812 on the filter screen plate 6.

[0036] As Figure 2 , Figure 3 , Figure 4 As shown in, as a preferred embodiment of the present invention, the telescopic component 92 includes a plurality of groups of annularly distributed first protrusions 921 fixedly installed on the surface of the filter screen plate 6. A side plate 922 is fixedly installed on the surface of the central shaft 7, and a plurality of groups of annularly distributed second protrusions 923 that cooperate with the first protrusions 921 are fixedly installed on the surface of the side plate 922.

[0037] When the central shaft 7 rotates, it drives the side plate 922 to rotate synchronously. The side plate 922 drives the second protrusions 923 to rotate synchronously. The second protrusions 923 cooperate with the first protrusions 921 to push the filter screen plate 6 to move in the inner cavity of the cylinder body 1. When the side plate 922 continuously rotates, the filter screen plate 6 continuously makes small-amplitude reciprocating movements in the inner cavity of the cylinder body 1.

[0038] The working principle of the present invention is: during use, the air extraction device conveys air into the cylinder body 1. When the air flows in the inner cavities of the two cylinder bodies 1, it will pass through the mesh holes on the surface of the plurality of filter screen plates 6. The filter screen plates 6 can filter the dust and impurities in the air, and the dust and impurities will adhere to the surface of the filter screen plates 6.

[0039] When filtering air, the motor 51 drives the column 5 to rotate, thereby driving the control disk 1023 to rotate in the water storage tank 4. The control disk 1023 drives the guide post 1024 to rotate synchronously. The guide post 1024 and the guide groove 1022 cooperate with each other to control the reciprocating movement of the cross bar 1021 in the inner cavity of the water storage tank 4. The cross bar 1021 and the connecting rod 1025 cooperate with each other to drive the piston disk 1026 to move synchronously. When the piston disk 1026 moves towards the water filling cylinder 1012 and further inserts into the water filling cylinder 1012, the piston disk 1026 can send the water pressure in the water filling cylinder 1012 into the water guide pipe 1013, and further send the water to the spray pipe 1011 under high pressure. The spray pipe 1011 atomizes the water and evenly sprays it into the inner cavity of the cylinder body 1. The atomized water fully contacts the dust and impurities in the air, and the filter mesh plate 6 can efficiently filter the dust and impurities.

[0040] The rotation of the column 5 drives the rotation of the driving bevel gear disk 814. The driving bevel gear disk 814 and the driven bevel gear disk 813 are engaged and transmitted to drive the central shaft 7 to rotate in the inner cavity of the cylinder body 1. The central shaft 7 drives the cleaning rod 811 to rotate, and the cleaning rod 811 drives the brush 812 to rotate outside the filter mesh plate 6. The brush 812 can automatically clean the dust and impurities attached to the surface of the filter mesh plate 6. After the brush 812 cleans the dust and impurities attached to the surface of the filter mesh plate 6, the dust and impurities fall to the inner bottom wall of the cylinder body 1. The dust and impurities pass through the drainage port 821 at the bottom of the filter mesh plate 6 and further slide downward and finally fall into the bottom cylinder 3. When the dust and impurities in the bottom cylinder 3 accumulate to a certain extent, the drainage pipe 822 is opened, and the dust and impurities can be conveniently discharged from the bottom cylinder 3.

[0041] When the central shaft 7 rotates, it drives the side plate 922 to rotate synchronously. The side plate 922 drives the second protrusion 923 to rotate synchronously. The second protrusion 923 and the first protrusion 921 cooperate with each other to push the filter mesh plate 6 to move in the inner cavity of the cylinder body 1. The side plate 922 continues to rotate, and the filter mesh plate 6 continuously moves back and forth in a small amplitude in the inner cavity of the cylinder body 1. When the filter mesh plate 6 moves back and forth, the brush 812 can be inserted into the mesh holes on the surface of the filter mesh plate 6, which can further improve the cleaning effect of the brush 812 on the filter mesh plate 6.

[0042] The above has described the preferred embodiments of the present invention in detail, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
