Description

Technical Field

[0001] The present invention belongs to the technical field of air filtration, and particularly relates to an air filtration device for low carbon emissions. Background Art

[0002] An air filter refers to an air filtration device. Using an air filtration device can purify the air entering the factory building equipment, make the equipment run more smoothly, reduce energy consumption, and thus indirectly reduce carbon emissions.

[0003] When it is necessary to filter the air in factories related to iron or ferroalloys such as metal processing and machinery manufacturing, the air filtration device is usually directly placed in the factory building, and the filter plate in the air filtration device is used to filter impurities and dust in the factory building air. However, during mechanical processing operations such as turning, milling, and drilling of equipment in the factory building, the cutting tool will cut the metal workpiece, generating a large number of fine iron filings. Under the frictional action of the high-speed rotating cutting tool and the workpiece, these iron filings will fly into the air. At this time, the air will contain fine iron filings. When the air filtration device transports the air containing iron filings to the filter plate for filtration, under the action of air flow, the high-speed moving iron filings will continuously impact the surface of the filter plate. Long-term impact and friction will cause the fiber material or other components of the filter plate to gradually wear, reducing its filtration performance. And larger-sized or sharp iron filings may directly pierce the filter plate. Once the filter plate has perforations, the unfiltered air will directly pass through these holes, resulting in a significant decline in the filtration effect, being unable to effectively remove other pollutants in the air, seriously affecting the air quality in the factory building, and greatly reducing the filtration effect and reliability of the air inside the factory building.

Then, the filtered air will be re-discharged into the factory through the air outlet holes 6 to complete the filtration of the air inside the factory.

[0019] In the embodiment, the transmission assembly 10 includes a first gear 101 fixedly connected to the outer wall of the rotating ring 9. A first motor 102 is fixedly connected to one end inner wall of the installation cavity 8. The output end of the first motor 102 is fixedly connected to a second gear 103, and the second gear 103 meshes with the first gear 101. The iron filings extraction assembly 11 includes an extraction ring 111 fixedly connected to one side wall of the rotating ring 9. A plurality of support rods 112 are fixedly connected to the inner wall of the extraction ring 111. One end of each support rod 112 is fixedly connected to the same diversion ring 113. A plurality of groups of mounting plates 114 are fixedly connected to the inner wall of the extraction ring 111. Each group of mounting plates 114 has two. First grooves 115 are formed in the opposite side walls of each group of mounting plates 114. A second groove 116 is formed in the bottom inner wall of one of the first grooves 115. A first pressure sensor 117 is fixedly connected to the bottom inner wall of the second groove 116.

[0020] Specifically, when it is necessary to filter the dust and impurities in the air inside the factory, the electromagnet 1114 can be used to adsorb the iron filings mixed in the air, preventing the iron filings from impacting the surface of the filter plate 3 and causing the fiber material or other components of the filter plate 3 to gradually wear, reducing its filtering performance. And it can continuously detect whether the surface of the electromagnet 1114 is full of iron filings. After detecting that the corresponding electromagnet 1114 is full of iron filings, the electromagnet 1114 with the surface full of iron filings is powered off. The iron filings adsorbed on the surface of the electromagnet 1114 will fall into the discharge port 1118 through the corresponding communication port 1119 to complete the collection of the iron filings. At the same time, the cleaning plate 1117 is used to clean the side of the electromagnet 1114 that adsorbs the iron filings, preventing the iron filings from continuing to adhere to the surface of the electromagnet 1114 due to the water on the surface of the iron filings when the air is relatively humid, which is convenient for subsequent use of the electromagnet 1114 to adsorb the iron filings in the air.

[0021] In the embodiment, the anti-blocking component 13 includes two fifth grooves 131 symmetrically formed in the inner wall of the housing 1.

The inner walls of the sixth grooves 139 are fixedly connected with second electric slide rails 1310. The side walls of the opposite ends of the two second electric slide rails 1310 are slidably connected with the same second slide plate 1311; One end side wall of the second slide plate 1311 is fixedly connected with a fourth electric telescopic rod 1312. The telescopic end of the fourth electric telescopic rod 1312 is fixedly connected with an auxiliary plate 1313. One end side wall of the auxiliary plate 1313 is fixedly connected with a connection shell 1314. A plurality of auxiliary cleaning holes 1315 are formed in one end side wall of the connection shell 1314. One end side wall of the connection shell 1314 is fixedly connected with an air pump 1316. The air outlet end of the air pump 1316 penetrates through the side wall of the connection shell 1314 and extends inward.

[0022] Specifically, the dust, copper chips and other metal impurities accumulated on one side of the filter plate 3 can be scraped to the bottom of the housing 1 by the scraper 135, preventing the accumulated dust, copper chips and other metal impurities from affecting the air filtration effect of the filter plate 3. And the second pressure sensor 137 is used to detect whether the surface of the filter plate 3 is damaged, preventing the unfiltered air from directly passing through the damaged part on the surface of the filter plate 3, resulting in a significant decline in the filtration effect. This greatly improves the air filtration effect and reliability of the device for the internal air of the factory building.

[0023] The operating principle of the present invention is described as follows: In the present invention, when it is necessary to filter dust and impurities in the air inside the factory, two blowers are controlled to start, and air is conveyed to one side of the filter plate 3 through the air inlet hole 7. The filter plate 3 is used to filter impurities and dust in the air. After that, the filtered air will be discharged back into the factory through the air outlet hole 6 to complete the filtration of the air inside the factory. During the air filtration process, under the cooperation of the diversion ring 113 and the retaining ring 12, when the air passes through the air inlet hole 7, it will pass through the electromagnets 1114 arranged inside the extraction ring 111. At this time, a plurality of electromagnets 1114 facing the middle part of the extraction ring 111 are energized, so that the corresponding electromagnets 1114 generate magnetic force. Then, the first electric telescopic rod 1113 is controlled to start, driving the corresponding electromagnets 1114 to move towards the middle part of the extraction ring 111, so that the electromagnets 1114 can contact the air entering the housing 1. When the air passes through the electromagnets 1114, iron filings in the air will be adsorbed by the electromagnets 1114, so that the air entering the housing 1 does not contain iron filings, preventing the iron filings from impacting the surface of the filter plate 3 and causing the fiber material or other components of the filter plate 3 to gradually wear, reducing its filtration performance. During the process of adsorbing iron filings in the air by the electromagnets 1114, the first motor 102 is controlled to start, driving the second gear 103 to rotate. During the rotation of the second gear 103, the first gear 101 will be driven to rotate continuously, so that the rotating ring 9 drives the extraction ring 111 to rotate. Whenever one of the energized electromagnets 1114 is located directly below the extraction ring 111 and the corresponding communication port 1119 is opposite to the discharge port 1118, at this time, the electromagnet 1114 is perpendicular to the ground. At this time, the corresponding first pressure sensor 117 is controlled to start. Since the weight of the electromagnet 1114 will continuously increase during the process of continuously adsorbing iron filings by the electromagnet 1114, it will drive a corresponding pressure on the corresponding support spring 118. When the corresponding first pressure sensor 117 detects that the pressure driven by the support spring 118 is too large, it means that the surface of the electromagnet 1114 here is full of iron filings. At this time, the first motor 102 is controlled to turn off. Then, the corresponding first electric telescopic rod 1113 is controlled to contract. Then, the second motor 1111 is controlled to start, driving the rotating rod 1112 to rotate 180 degrees and then stop. At this time, another electromagnet 1114 faces the middle part of the extraction ring 111, (energize this electromagnet 1114 to continue adsorbing iron filings mixed in the air), and the electromagnet 1114 with its surface full of iron filings faces down. At this time, the electromagnet 1114 with its surface full of iron filings is powered off. At this time, the corresponding electromagnet 1114 does not generate magnetic force, and the iron filings adsorbed on the surface of the electromagnet 1114 will fall into the discharge port 1118 through the corresponding communication port 1119. Finally, the iron filings will fall into the installation cavity 8 to complete the collection of iron filings. During this process, the corresponding second electric telescopic rod 1116 is controlled to contract, so that the cleaning plate 1117 moves towards the direction of the powered-off electromagnet 1114.The cleaning plate 1117 is used to clean the side of the electromagnet 1114 that absorbs iron filings to prevent the iron filings from continuing to adhere to the surface of the electromagnet 1114 due to water on the surface of the iron filings when the air is relatively humid. The cleaning plate 1117 is used to clean the iron filings adhering to the surface of the electromagnet 1114 to facilitate the subsequent use of the electromagnet 1114 to absorb the iron filings in the air. Then, the first motor 102 is controlled to continue to start, driving the multiple electromagnets 1114 to continue to rotate. According to the above steps, whether the surfaces of other electromagnets 1114 are full of iron filings is continued to be detected. In addition to iron filings, other metal impurities such as copper filings are easily mixed in the air in the factory. At this time, the electromagnet 1114 cannot absorb other metal impurities such as copper filings. The dust and other metal impurities such as copper filings accumulated on one side of the filter plate 3 are then removed by the scraper 135 and the auxiliary plate 1313. The scraper 135 is used to scrape and clean the impurities. When the surface of the filter plate 3 is scratched by sharp copper filings or other metal impurities, the air blown out of the auxiliary cleaning hole 1315 will be directly blown to the detection plate 138 through the scratched part of the surface of the filter plate 3. At this time, the pressure detected by the second pressure sensor 137 will increase, indicating that the surface of the filter plate 3 is damaged and needs to be cleaned. The plate 3 can be replaced to prevent unfiltered air from directly passing through the scratched part, which would greatly reduce the filtering effect. When it is necessary to filter dust and impurities in the air inside the factory, the electromagnet 1114 can be used to absorb iron filings mixed in the air to prevent the iron filings from impacting the surface of the filter plate 3, causing the fiber material or other components of the filter plate 3 to gradually wear out and reduce its filtering performance. In addition, the electromagnet 1114 can continuously detect whether the surface of the electromagnet 1114 is full of iron filings. After detecting that the corresponding electromagnet 1114 is full of iron filings, the electromagnet 1114 with the surface full of iron filings is powered off, and the iron filings adsorbed on the surface of the electromagnet 1114 will fall into the discharge port 1118 through the corresponding connecting port 1119, thereby completing the collection of the iron filings.Meanwhile, the cleaning plate 1117 is used to clean the side of the electromagnet 1114 that adsorbs iron filings, preventing the iron filings from continuing to adhere to the surface of the electromagnet 1114 due to the water on the surface of the iron filings when the air is relatively humid, facilitating the subsequent continuous use of the electromagnet 1114 to adsorb iron filings in the air. The scraper 135 can also be used to scrape the dust, copper filings and other metal impurities accumulated on one side of the filter plate 3 to the bottom of the housing 1, preventing the accumulated dust, copper filings and other metal impurities from affecting the air filtration effect of the filter plate 3. In addition, the second pressure sensor 137 is used to detect whether there is damage on the surface of the filter plate 3, preventing the unfiltered air from directly passing through the damaged part on the surface of the filter plate 3, resulting in a significant decrease in the filtration effect. This greatly improves the air filtration effect and reliability of the device for the internal air of the factory building.
