[0002] Air pollution is the phenomenon that certain substances enter the atmosphere due to human activities or natural processes, appear in sufficient concentrations and for sufficient time to endanger human comfort, health and welfare or the environment.

[0003] In order to prevent particles, rubber and other impurities in the exhaust gas from entering the regenerative thermal oxidizer and causing blockage, a filter will be set at the front end of the regenerative thermal oxidizer. The exhaust gas enters after passing through the filter to filter out particles, tar and other impurities in the exhaust gas. In the process of filtering the exhaust gas, the filtered particles and other impurities are easily accumulated on the filter, which reduces the filtering efficiency and affects the normal operation of the device. Therefore, the staff needs to clean it regularly. However, during the cleaning process, the filter device cannot work, so the regenerative thermal oxidizer needs to stop and wait, which greatly affects the treatment of the exhaust gas. For this reason, we propose an atmospheric environmental pollution control and cleaning equipment. Summary of the Invention

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1

[0039] See also Figures 1-11 , the present invention provides a technical solution:

[0040] An atmospheric environmental pollution control and cleaning device includes an air inlet pipe 1 connected to a thermal oxidation furnace, and further includes:

[0041] The intermediate pipe 2 is connected to the air intake pipe 1, and the diameter of the intermediate pipe 2 is larger than that of the air intake pipe 1. A plurality of rotatable filters 3 can be set in the intermediate pipe 2 to ensure the filtration of the air intake pipe 1 by switching.

[0042] Multiple filters 3 are movably arranged in the middle pipe 2 for filtering the gas entering the intake pipe 1. In this embodiment, there are three filters 3. When the shift plate 71 rotates 120 degrees, a cleaned filter 3 can be replaced.

[0043] An automatic switching unit 4 is provided on the air intake pipe 1 and the intermediate pipe 2 and is connected to the plurality of filters 3. Gas entering the air intake pipe 1 drives the automatic switching unit 4 to accumulate force. When the filter 3 in the air intake pipe 1 is blocked, the automatic switching unit 4 is triggered and releases the force, driving the plurality of filters 3 to automatically rotate and switch.

[0044] The automatic switching unit 4 includes a support frame 41 provided on the air intake duct 1, and a wind drive assembly 5 is provided on the support frame 41 for storing force when air is taken into the air intake duct 1. A positioning frame 42 is slidably provided on the air intake duct 1, and a resistance trigger assembly 7 is provided on the positioning frame 42 for driving the wind drive assembly 5 to release force when the filter 3 in the air intake duct 1 is blocked. A reset member 9 is provided in the intermediate duct 2 for pushing the other filter 3 to fit into the air intake duct 1 after rotation. A plurality of detachable cleaning members 10 are provided on the intermediate duct 2 for removing the blocked filter 3 for cleaning.

[0045] The wind drive assembly 5 includes a second support frame 51 arranged on the inner wall of the air intake duct 1, a drive shaft 52 and a stepped shaft 53 are rotatably provided on the second support frame 51, a fan blade 54 is provided on the drive shaft 52, a bevel gear 55 used in conjunction with each other is provided on the drive shaft 52 and the stepped shaft 53, a transmission shaft 56 is rotatably provided on the second support frame 51, the stepped shaft 53 is rotatably connected to the support frame 1 41, a bevel gear 2 57 is provided on the stepped shaft 53 and the transmission shaft 56, a rotating rod 58 is provided on the bevel gear 2 57 located on the transmission shaft 56, and a force storage member 6 used in conjunction with the rotating rod 58 is provided on the air intake duct 1, for storing force when the rotating rod 58 rotates;

[0046] The force storage member 6 includes a ratchet 61 rotatably arranged on the rotating rod 58, and a ratchet 62 cooperating with the ratchet 61 is rotatably arranged on the positioning frame 42 through a bearing. A spring 63 cooperating with the ratchet 61 is provided on the rotating rod 58, and the positioning frame 42 is provided with a spring spring 64. The two ends of the spring spring 64 are respectively connected to the ratchet 62 and the positioning frame 42. The rotation of the fan blade 54 drives the drive shaft 52 to rotate, and under the action of the bevel gear 55, the stepped shaft 53 is driven to rotate, and then under the action of the bevel gear 2 57, the transmission shaft 56 is driven to rotate. At this time, the ratchet 61 can drive the ratchet 62 to rotate, and the spring 64 starts to store force. When the force storage is completed, the fan blade 54 can no longer rotate. Due to the direction of the ratchet 2 83 and the ratchet 2 81, the ratchet 2 81 does not rotate during this process. At this time, the stored force can just drive the shift plate 71 to rotate 120°, that is, a cleaned filter 3 is replaced for use;

[0047] The resistance trigger assembly 7 includes a shift plate 71 slidably disposed within the intermediate pipe 2. A plurality of filters 3 are evenly embedded in the shift plate 71. A rotating shaft 72 is disposed in the middle of the shift plate 71. The rotating shaft 72 is rotatably connected to the positioning frame 42. A transmission member 8 connected to the ratchet 1 62 is disposed on the intake pipe 1 to enable the rotating shaft 72 to transmit in only one direction.

[0048] The transmission member 8 includes a second ratchet 81 provided on the rotating shaft 72, and a fixing rod 82 is provided on the ratchet 1 62. A second ratchet 83 is rotatably provided on the fixing rod 82 to cooperate with the second ratchet 81, and a second spring 84 is provided on the fixing rod 82 to cooperate with the second ratchet 83. When the filter 3 in the intake duct 1 is blocked to a certain extent, the filter 3 and the shift plate 71 can be shifted synchronously. At this time, the ratchet 1 62 and the ratchet 1 61 are disengaged, and the clockwork spring 64 is released. At this time, the second ratchet 83 can drive the second ratchet 81 and the rotating shaft 72 to rotate, completing the switching of the filter 3. After switching, the surface of the filter 3 is not blocked, the resistance is small, and normal ventilation can be achieved. Then, under the action of the return spring 92, the filter 3 is lifted up to continue filtering the intake duct 1;

[0049] In order to enable the ratchet 1 62 to engage with the ratchet 1 61 again and ensure the next use, the contact position between the ratchet 1 61 and the ratchet 1 62 can be chamfered;

[0050] The reset member 9 includes a bottom plate 91 rotatably mounted on the intermediate pipe 2 , and a plurality of reset springs 92 are mounted on the bottom plate 91 . The plurality of reset springs 92 are respectively connected to the shift plate 71 . The bottom plate 91 is provided with an opening corresponding to the filter screen 3 .

[0051] The side of the intermediate pipe 2 away from the clockwork spring 64 is thicker than the other side. The detachable cleaning part 10 includes a sealing circular plate 101 slidably arranged in the intermediate pipe 2. A screw 102 is threadedly connected to the intermediate pipe 2. The sealing circular plate 101 and the screw 102 are rotatably connected. A disassembly circular plate 103 is threadedly connected to the side of the intermediate pipe 2 close to the clockwork spring 64. After replacing the filter 3, the screw 102 can be rotated to shift the sealing circular plate 101 to fit with the movable plate to avoid air leakage. Then, the disassembly circular plate 103 can be unscrewed, and the filter 3 can be removed for cleaning. After cleaning and reinstalling, the disassembly circular plate 103 and the sealing circular plate 101 can be reset.

[0052] When in use, the device introduces the gas to be treated through the air inlet pipe 1. After entering the intermediate pipe 2, the gas first passes through the currently working filter 3 for filtration. At the same time, the fan blade 1 54 rotates under the action of the gas flow, driving the drive shaft 52, the stepped shaft 53, the transmission shaft 56 and the rotating rod 58 to rotate in sequence. The ratchet 1 61 on the rotating rod 58 drives the ratchet 1 62 to rotate, and the spring spring 64 begins to accumulate force. At this time, the ratchet 2 81 does not rotate due to the direction setting, keeping the filter 3 in a stable position.

[0053] When the filter 3 is clogged to a certain extent, the gas flow is blocked, the filter 3 and the shift plate 71 shift synchronously, the ratchet 1 62 and the ratchet 1 61 disengage, the clockwork spring 64 releases energy, driving the ratchet 2 83 and the ratchet 2 81 to rotate, and the ratchet 2 81 drives the shift plate 71 to rotate 120 degrees through the rotating shaft 72, switching to the next cleaned filter 3. After the switch, the surface of the filter 3 is clean and the resistance is small, allowing the gas to pass normally. At the same time, the shift plate 71 is lifted up by the reset spring 92 to continue filtering;

[0054] After the switching is completed, the screw 102 can be rotated to make the sealing circular plate 101 fit with the shift plate 71 to avoid air leakage, and the disassembly circular plate 103 can be unscrewed to remove the blocked filter 3 for cleaning. After cleaning and reinstalling, the disassembly circular plate 103 and the sealing circular plate 101 are reset, and the equipment is restored to its initial state to prepare for the next round of filtration. The specially designed ratchet 61 and ratchet wheel 62 are chamfered to ensure smooth engagement after switching. The thickness design of the middle pipe 2 provides sufficient installation space, and the detachable cleaning part 10 facilitates the disassembly and cleaning of the filter 3.

[0055] Example 2

[0056] See also Figure 12-14 , the present invention provides a technical solution:

[0057] Different from Example 1, the shift plate 71 is provided with a plurality of rotating rings 111, and the plurality of filter screens 3 are rotatably provided on the rotating rings 111 respectively. A rotating member 11 is provided in the air intake duct 1 for driving the filter screen 3 in the air intake duct 1 to rotate. The rotating member 11 includes a mounting frame 112 provided on the air intake duct 1, a fixed shaft 113 is rotatably provided in the middle of the mounting frame 112, and a fan blade 2 114 is provided on the fixed shaft 113. A polygonal groove seat 1 115 is provided in the middle of each of the filter screens 3. A connecting member 12 is provided in the air intake duct 1 to cooperate with the polygonal groove seat 115, and is used to drive the filter screen 3 to rotate synchronously when the fixed shaft 113 rotates;

[0058] The connecting member 12 includes a polygonal groove seat 2 121 arranged on the side of the fixed shaft 113 close to the filter 3, a connecting spring 122 is arranged in the polygonal groove seat 2 121, and a polygonal rod 123 is arranged at the end of the connecting spring 122. The two ends of the polygonal rod 123 are respectively inserted into the polygonal groove seat 1 115 and the polygonal groove seat 2 121, and the end of the polygonal rod 123 close to the polygonal groove seat 1 115 is chamfered.

[0059] When in use, the device introduces the gas to be treated through the air inlet pipe 1. After entering the intermediate pipe 2, the gas first passes through the currently working filter 3 for filtration. At the same time, the fan blade 1 54 rotates under the action of the gas flow, driving the drive shaft 52, the stepped shaft 53, the transmission shaft 56 and the rotating rod 58 to rotate in sequence. The ratchet 1 61 on the rotating rod 58 drives the ratchet 1 62 to rotate, and the spring spring 64 begins to accumulate force. At this time, the ratchet 2 81 does not rotate due to the direction setting, keeping the filter 3 in a stable position.

[0060] When the filter 3 is clogged to a certain extent, the gas flow is blocked, the filter 3 and the shift plate 71 shift synchronously, the ratchet 1 62 and the ratchet 1 61 disengage, the polygonal rod 123 disengages from the polygonal slot seat 115 on the filter 3, so that the filter 3 and the first plate can rotate, the clockwork spring 64 releases energy, driving the ratchet 2 83 and the ratchet 2 81 to rotate, the ratchet 2 81 drives the shift plate 71 to rotate 120 degrees through the rotating shaft 72, and switches to the next cleaned filter 3. The switched filter 3 surface is clean, resistance is small, gas passes normally, at the same time, under the action of the return spring 92, the shift plate 71 is pushed up to continue filtering, the aperture on the filter 3 is small, when rotating, the polygonal rod 123 will not be stuck, after rotation, under the action of the connecting spring 122, the polygonal rod 123 is pushed back into the polygonal groove seat 1 15, due to the setting of the rotating ring 111, the fan blade 2 114 drives the polygonal groove seat 2 121, the polygonal groove seat 1 115 and the filter 3 to rotate through the fixed shaft 113;

[0061] After the switching is completed, the screw 102 can be rotated to make the sealing circular plate 101 fit with the shift plate 71 to avoid air leakage, and the disassembly circular plate 103 can be unscrewed to remove the blocked filter 3 for cleaning. After cleaning and reinstalling, the disassembly circular plate 103 and the sealing circular plate 101 are reset, and the equipment is restored to its initial state to prepare for the next round of filtration. The specially designed ratchet 61 and ratchet wheel 62 are chamfered to ensure smooth engagement after switching. The thickness design of the middle pipe 2 provides sufficient installation space, and the detachable cleaning part 10 facilitates the disassembly and cleaning of the filter 3.
