Description

Technical Field

[0001] This invention relates to the field of air pollutant control technology, and in particular to an outdoor air pollutant control device. Background Technology

[0002] In the process of treating air pollutants, filters are mainly used. While simple in construction and low in cost, dust accumulates on the outside of the filters during actual treatment. This requires manual cleaning at regular intervals, which is time-consuming and labor-intensive. Furthermore, cleaning necessitates removing the filter element from the treatment equipment, which is quite troublesome. Additionally, a pressure sensor is fixedly installed on the outside of the filter element. When the filter element is damaged, the pressure sensor will emit an abnormal electrical signal, allowing for timely adjustments. However, in actual operation, the pressure sensor's position is fixed, only measuring whether damage has occurred in a specific area of ​​the filter element, and not providing a timely understanding of the overall working condition of the filter element. Therefore, this paper proposes an outdoor air pollutant treatment device. Summary of the Invention

A control rod is fixedly connected to the lower side of the square rod. The control rod is threaded through the preservation box. The control rod is rotatably connected to one of the connecting plates.

[0008] Preferably, two baffles are symmetrically fixedly connected inside the storage box.

[0009] Preferably, a sealing mesh is fixedly connected to the outer side of the motor protective shell, and multiple inclined plates are fixedly connected to the outer side of the fixing frame.

[0010] Preferably, the filter element has multiple mounting slots on its outer side, and a locking screw is threaded through the outer side of the fixing frame, with one end of the locking screw extending into the mounting slot and threadedly connected to the mounting slot.

[0028] See Figures 1-11 An outdoor air pollutant treatment device includes a mounting frame 1. Multiple motor protective shells 2 are fixedly mounted on the upper side of the mounting frame 1. A power motor 7 is fixedly connected inside the motor protective shell 2. Multiple axial flow fans 8 are fixedly connected to the outside of the output shaft of the power motor 7. A fixing frame 4 is fixedly connected to the outside of the motor protective shell 2. A filter element 6 is fixedly mounted inside the fixing frame 4. Multiple mounting slots are opened on the outside of the filter element 6. A locking screw 5 is threaded through the outside of the fixing frame 4. One end of the locking screw 5 extends to the mounting slot and is threadedly connected to the mounting slot. A sealing mesh 3 is fixedly connected to the outside of the motor protective shell 2. Multiple inclined plates are fixedly connected to the outside of the fixing frame 4.

[0029] First, place the filter element 6 inside the fixed frame 4, and rotate the locking screw 5 so that it passes through the fixed frame 4 and is screwed into the mounting groove, completing the fixed installation of the filter element 6. Then, under the action of the sealing mesh 3 and the inclined plate, a certain degree of protection can be formed for the filter element 6 inside the fixed frame 4 and the power motor 7 inside the motor protective shell 2. Next, when it is necessary to absorb atmospheric pollutants, start the power motor 7, which drives the axial fan 8 to rotate. Figure 3From the perspective of the filter element, air can circulate from left to right, that is, air can enter from the fixed frame 4 and then flow out from the motor protective shell 2. At this time, under the action of the filter element 6, the air can absorb pollutants in the air and make the pollutants in the air stay on the surface of the filter element 6, thus forming the filtration and treatment of pollutants in the air. The above are all existing technologies and will not be elaborated further.

[0030] A cleaning assembly for the filter element 6 is installed inside the fixed frame 4. The cleaning assembly includes a positioning plate 17 fixedly installed on the outside of the filter element 6. A rotating cylinder 24 is rotatably connected to the positioning plate 17. A fixed cylinder 23 is rotatably connected to the outside of the rotating cylinder 24. The fixed cylinder 23 and the filter element 6 are fixedly connected. A circular plate 9 is fixedly connected to the outside of the rotating cylinder 24. A cleaning box 10 is fixedly connected to the circular plate 9 through a first connecting rod. An ultraviolet irradiation lamp 36 is fixedly connected inside the cleaning box 10. Two cleaning plates 37 are slidably connected inside the cleaning box 10. A connecting plate 33 is fixedly connected between the two cleaning plates 37. A circular rod 31 is fixedly connected to the lower side of the connecting plate 33. A compression spring 32 is fixedly connected between the connecting plate 33 and the cleaning box 10. An annular protrusion 26 is fixedly connected to the side wall of the fixed cylinder 23. The output shaft of the power motor 7 is connected to the rotating cylinder 24 through a transmission assembly.

[0031] Firstly, during filtration and treatment using filter element 6, air pollutants remain on its surface. Over prolonged operation, this accumulation gradually reduces the filtration efficiency. To address this, the transmission assembly drives the rotating cylinder 24 and activates the ultraviolet lamp 36. The circular plate 9, via the first connecting rod, rotates the cleaning box 10. The cleaning plate 37 on the outside of the cleaning box 10 abuts against the surface of filter element 6 and rotates with it. This contact removes the accumulated material from the filter element 6 surface, with most of the removed material falling into the cleaning box 10, thus completing the removal of large particulate pollutants. The collection operation reduces the possibility of secondary accumulation of large particulate pollutants on the surface of filter element 6. During this process, since the fixed cylinder 23 and filter element 6 are fixedly connected, and the annular protrusion 26 is fixedly connected to the fixed cylinder 23, the cleaning plate 37, which rotates with the cleaning box 10, is constantly pressed against the annular protrusion 26 under the action of the compression spring 32. As a result, the cleaning plate 37 moves back and forth relative to the cleaning box 10 during the rotation of the cleaning box 10. The round rod 31 drives the cleaning plate 37 to move back and forth relative to the cleaning box 10 through the connecting plate 33. The cleaning plate 37 presses against the filter element 6. The back-and-forth movement of the cleaning plate 37 can better clean the pollutants accumulated on the outside of the filter element 6.

[0032] Furthermore, during the aforementioned work process, the widths of the cleaning plates 37 on both sides are not the same, so as to... Figure 6 Based on the direction, when the rotating cylinder 24 and the circular plate 9 rotate clockwise, there is a certain gap between the cleaning plate 37 on the right and the filter element 6, and the cleaning plate 37 on the left and the filter element 6 are completely abutted. During the cleaning process using the cleaning plate 37, the abutting between the cleaning plate 37 on the left and the filter element 6 can form a treatment operation on the surface contaminants of the filter element 6. Then, under the action of the cleaning plate 37 on the right, the possibility of contaminants moving out of the cleaning plate 37 after cleaning can be effectively reduced, so that the contaminants after cleaning can remain completely in the cleaning box 10 as much as possible.

[0033] A detection assembly is installed on the outside of the rotating cylinder 24. The detection assembly includes a rotating shaft 25 that rotates through the rotating cylinder 24. A rotating plate 18 is fixedly connected to the outside of the rotating shaft 25. A pressure sensor 19 is fixedly connected to the outside of the rotating plate 18. A torsion spring 27 is fixedly connected between the rotating shaft 25 and the rotating cylinder 24. A second connecting rod 30 is fixedly connected to the outside of the round rod 31. A moving plate 28 is fixedly connected to one end of the second connecting rod 30 that extends into the rotating cylinder 24. A moving rod 29 is fixedly connected to the side wall of the rotating shaft 25. The moving rod 29 and the rotating shaft 25 are eccentrically arranged.

[0034] First, the pressure sensor 19 is an instrument used to measure gas pressure. Furthermore, the pressure sensor 19 converts the measured pressure into an electrical signal and transmits it to the corresponding working component (such as a computer), ultimately allowing the relevant personnel to know the actual working conditions within the fixed frame 4. During the filtration process using the filter element 6, the pressure sensor 19 can measure the pressure of the air after filtration. If the filter element 6 is damaged, it will cause the pressure sensor 19 to emit an abnormal signal, thus informing the personnel of the actual condition of the filter element 6. During this process, the rotating cylinder 24 drives the rotating shaft 25 and the rotating plate 18 via the torsion spring 27. The rotating plate 18 drives the pressure sensor 19 to rotate, which in turn changes the measurement position of the pressure sensor 19. This allows for measurement of multiple different positions of the filter element 6, providing a better understanding of the actual working condition of the filter element 6. During this process, the circular rod 31 moves up and down, which in turn drives the moving plate 28 to move up and down via the second connecting rod 30. The moving plate 28 and the moving rod 29 abut against each other, causing the moving rod 29 to drive the rotating shaft 25 to rotate. The rotating shaft 25 then drives the rotating plate 18 and the pressure sensor 19 to rotate. As the pressure sensor 19 rotates relative to the rotating cylinder 24, it causes the pressure sensor to rotate. The relative position between the pressure sensor 19 and the cleaning box 10 changes, meaning that the cleaning box 10 no longer blocks the air blowing towards the pressure sensor 19, and at the same time, the cleaning box 10 blocks the air blowing towards the pressure sensor 19. Initially, the cleaning box 10 does not block the air blowing towards the pressure sensor 19, and at this time, the pressure sensor 19 can detect the air passing through the filter element 6 and thus send a corresponding electrical signal. Then, as the pressure sensor 19 rotates relative to the rotating cylinder 24, it gradually changes from the state where the cleaning box 10 does not block the air blowing towards the pressure sensor 19 to the state where the cleaning box 10 blocks the air blowing towards the pressure sensor 19, resulting in... The electrical signal emitted by the pressure sensor 19 decreases until the cleaning box 10 completely blocks the air blowing towards the pressure sensor 19. At this point, the electrical signal emitted by the pressure sensor 19 is at its minimum. Then, the state changes from the state where the cleaning box 10 completely blocks the air blowing towards the pressure sensor 19 to the state where the cleaning box 10 does not block the air blowing towards the pressure sensor 19. The electrical signal emitted by the pressure sensor 19 gradually increases, eventually causing the electrical signal emitted by the pressure sensor 19 to change periodically during the rotation of the pressure sensor 19 relative to the rotating cylinder 24. The staff can observe the amplitude of the electrical signal change to know whether the filter element 6 is damaged, which is more intuitive and specific.

[0035] An intermittent preservation component is installed inside the cleaning box 10. The intermittent preservation component includes a preservation box 35 fixedly installed inside the cleaning box 10, so as to... Figure 11From the perspective of the storage box 35, the opening faces to the right. A fixed plate 39 is fixedly connected inside the storage box 35. A trapezoidal plate 38 is fixedly connected to the side wall of the fixed plate 39. A control cylinder 41 is rotatably connected through the fixed plate 39. Two control plates 42 are fixedly connected to the outside of the control cylinder 41. The two control plates 42 are located on both sides of the fixed plate 39 and abut against the fixed plate 39. A square rod 40 is slidably connected through the control cylinder 41. A control rod 34 is fixedly connected to the lower side of the square rod 40. The control rod 34 is threaded through the storage box 35. The control rod 34 is rotatably connected to one of the connecting plates 33. Two baffles are symmetrically fixedly connected inside the storage box 35.

[0036] When performing cleaning operations using cleaning plate 37, Figure 10 From the perspective of the ash, part of the generated ash falls on the upper side of the storage box 35 and the fixed plate 39, and the other part falls on the bottom of the cleaning box 10. During this process, the up-and-down moving cleaning plate 37 and connecting plate 33 will drive the control rod 34 to move up and down. Since the control rod 34 and the storage box 35 are threadedly connected, the control rod 34 will also rotate as it moves up and down with the connecting plate 33. The control rod 34 drives the square rod 40 to rotate, the square rod 40 drives the control cylinder 41 to rotate, and the control cylinder 41 drives the control plate 42 to rotate. This allows the contaminants located on the upper side of the fixed plate 39 to move into the storage box 35 under the action of the control plate 42, thereby completing the collection of contaminants. As the cleaning box 10 continues to rotate, the bottom of the cleaning box 10 will become the upper side of the cleaning box 10. At this time, under its own gravity, some of the contaminants here fall onto the fixed plate 39, so that most of the cleaned contaminants can be collected into the cleaning box 10.

[0037] It should be emphasized that the rotation diameter of the control board 42 is smaller than the length and width of the storage box 35, so as to ensure that the control board 42 can rotate one revolution.

[0038] like Figure 6 , Figure 7 The transmission assembly includes a straight plate 11 fixedly installed inside the motor protective housing 2. A rotating shaft is rotatably connected to the side wall of the straight plate 11. The rotating shaft is connected to the output shaft of the power motor 7 through a first pulley assembly 12. A first gear 13 is fixedly connected to the outside of the rotating shaft. A transmission shaft 14 is rotatably connected to the side wall of the straight plate 11. A second gear 15 is fixedly connected to the outside of the transmission shaft 14. The second gear 15 meshes with the first gear 13. A third gear 16 is fixedly connected to the outside of the transmission shaft 14. A connecting shaft 20 is rotatably connected to the side wall of the positioning plate 17. A fourth gear 22 is fixedly connected to the outside of the connecting shaft 20. The third gear 16 meshes with the fourth gear 22. The rotating cylinder 24 is connected to the connecting shaft 20 through a second pulley assembly 21.

[0039] First, during the process of the power motor 7 driving the axial flow fan 8 to rotate, the output shaft of the power motor 7 drives the rotating shaft to rotate through the first pulley assembly 12. The rotating shaft drives the transmission shaft 14 to rotate through the first gear 13 and the second gear 15. After the filter element 6 is installed, the third gear 16 and the fourth gear 22 are in a meshing state. Therefore, the rotating transmission shaft 14 will drive the connecting shaft 20 to rotate through the third gear 16 and the fourth gear 22. The connecting shaft 20 drives the rotating cylinder 24 to rotate through the second pulley assembly 21. In the above working process, the diameters of the first gear 13 and the second gear 15 are significantly different. That is, although the axial flow fan 8 rotates very fast when the power motor 7 drives it, the rotation speed of the transmission shaft 14 is relatively slow under the transmission action of the first gear 13 and the second gear 15. In other words, the rotation speed of the rotating cylinder 24 is relatively slow, which will not affect the pollutant treatment operation.

[0040] In this invention, when it is necessary to absorb air pollutants, the power motor 7 is started, and the power motor 7 drives the axial flow fan 8 to rotate, so that the air flows from left to right. Under the action of the filter element 6, the air can absorb the pollutants in the air, so that the pollutants in the air remain on the surface of the filter element 6, and finally the filtration and treatment of the pollutants in the air is formed. The above are all existing technologies and will not be described in detail.

[0041] When using filter element 6 for filtration and treatment, as the contaminants on the surface of filter element 6 gradually become excessive, the transmission assembly drives the rotating cylinder 24 to rotate, activating the ultraviolet irradiation lamp 36. The circular plate 9 drives the cleaning box 10 to rotate. The cleaning plate 37 on the outside of the cleaning box 10 abuts against the surface of filter element 6 and rotates with the cleaning box 10, which can remove the material accumulated on the surface of filter element 6. Most of the removed material falls into the cleaning box 10. During this process, the circular rod 31 abuts against the annular protrusion 26, causing the circular rod 31 to move back and forth relative to the cleaning box 10. The circular rod 31 drives the cleaning plate 37 to move back and forth relative to the cleaning box 10 through the connecting plate 33. The cleaning plate 37 abuts against the filter element 6, and the back-and-forth movement of the cleaning plate 37 can better clean the contaminants accumulated on the outside of filter element 6.

[0042] When the rotating cylinder 24 and the circular plate 9 rotate clockwise, there is a certain gap between the cleaning plate 37 on the right and the filter element 6, and the cleaning plate 37 on the left and the filter element 6 are completely in contact. The contact between the cleaning plate 37 on the left and the filter element 6 can form a treatment operation for the contaminants on the surface of the filter element 6. Under the action of the cleaning plate 37 on the right, the possibility of the contaminants moving out of the cleaning plate 37 after cleaning can be effectively reduced, and the contaminants after cleaning can be kept completely in the cleaning box 10 as much as possible.

[0043] The pressure sensor 19 measures the pressure of the air after it has been filtered by the filter element 6. If the filter element 6 is damaged, the pressure sensor 19 will send an abnormal signal, allowing staff to know the actual condition of the filter element 6. The rotating cylinder 24 drives the rotating shaft 25 and the rotating plate 18 to rotate via the torsion spring 27. The rotating plate 18 drives the pressure sensor 19 to rotate, changing the measurement position of the pressure sensor 19 and allowing it to measure multiple different positions of the filter element 6. The round rod 31 drives the moving plate 28 to move up and down via the second connecting rod 30. The moving plate 28 and the moving rod 29 abut against each other, causing the moving rod 29 to drive the rotating shaft 25 to rotate. The rotating shaft 25 drives the rotating plate 18 and the pressure sensor 19 to rotate. During the rotation of the pressure sensor 19 relative to the rotating cylinder 24, the relative position between the pressure sensor 19 and the cleaning box 10 changes, meaning that the cleaning box 10 will not block the air blowing towards the pressure sensor 19. The cleaning box 10 blocks the air blowing towards the pressure sensor 19. As the pressure sensor 19 rotates relative to the rotating cylinder 24, it gradually changes from a state where the cleaning box 10 does not block the air blowing towards the pressure sensor 19 to a state where the cleaning box 10 blocks the air blowing towards the pressure sensor 19. This causes the electrical signal emitted by the pressure sensor 19 to decrease until the cleaning box 10 completely blocks the air blowing towards the pressure sensor 19. At this point, the electrical signal emitted by the pressure sensor 19 is at its minimum. Then, it changes from a state where the cleaning box 10 completely blocks the air blowing towards the pressure sensor 19 to a state where the cleaning box 10 does not block the air blowing towards the pressure sensor 19. The electrical signal emitted by the pressure sensor 19 gradually increases. Ultimately, as the pressure sensor 19 rotates relative to the rotating cylinder 24, the electrical signal emitted by the pressure sensor 19 changes periodically. The staff can observe the amplitude of the electrical signal change to know whether the filter element 6 is damaged, which is more intuitive and specific.

[0044] During the cleaning operation using the cleaning plate 37, some of the generated ash falls onto the upper side of the storage box 35 and the fixed plate 39, while the other part falls onto the bottom of the cleaning box 10. The vertically moving cleaning plate 37 and connecting plate 33 drive the control rod 34 to move vertically. The control rod 34 rotates, which in turn drives the square rod 40 to rotate. The square rod 40 then drives the control cylinder 41 and control plate 42 to rotate. This allows the contaminants located on the upper side of the fixed plate 39 to move into the storage box 35 under the action of the control plate 42, thus completing the collection of contaminants. As the cleaning box 10 continues to rotate, the bottom of the cleaning box 10 becomes the upper side of the cleaning box 10. At this time, under its own gravity, some of the contaminants fall onto the fixed plate 39, ultimately allowing most of the cleaned contaminants to be collected into the cleaning box 10.
