Description

Technical Field

[0001] This invention belongs to the field of waste gas treatment technology, and particularly relates to an indoor waste gas treatment device. Background Technology

[0002] In modern life, indoor air quality is crucial to people's health. A wide range of indoor pollutants, such as formaldehyde and benzene released from building materials, cooking fumes, and carbon dioxide exhaled by humans, can seriously affect indoor air quality and endanger human health.

[0003] Before exhausting indoor waste gas, it is usually necessary to purify it. Current technology generally uses high-efficiency activated carbon to purify indoor waste gas. However, if there is a lot of dust in the indoor environment, such as during renovation construction or cleaning when there is a lot of dust, the waste gas will contain a lot of dust. This dust will adhere to the surface of the high-efficiency activated carbon plate, clogging its pores and reducing the purification efficiency of the high-efficiency activated carbon for indoor waste gas. Furthermore, after the dust has blocked most of the activated carbon surface, the activated carbon surface cannot quickly circulate indoor waste gas. At this point, the staff still need to remove the activated carbon from the indoor waste gas treatment device, clean the dust clogging the surface of the activated carbon, and then reinstall the activated carbon in the indoor waste gas treatment device. The process is complicated and greatly reduces the purification efficiency and reliability of indoor waste gas treatment.

A detection plate and pressure sensor detect significant dust blockage. Upon detection, the activated carbon plate is moved into the outer casing. The limiting plate then prevents the mounting frame and activated carbon plate from being fixed, allowing them to sway. A vibrating shell then vibrates the activated carbon plate, discharging dust adhering to one side. Air outlets further blow out the dust blocking the activated carbon plate, completing the cleaning process. A nozzle and water pump dissolve the dust discharged from one side of the activated carbon plate in water, which then falls into the fifth groove for collection, preventing dust from scattering. This eliminates the need for personnel to remove the activated carbon from the indoor exhaust gas treatment device and clean the surface blockage, significantly improving the purification efficiency and reliability of the device.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] The following electrical components are all electrically connected to the external PLC controller.

[0029] Reference Figure 1 - Figure 10An indoor exhaust gas treatment device includes a treatment shell 1, a support rod 2 fixedly connected to the inner wall of the bottom end of the treatment shell 1, an exhaust fan 3 fixedly connected to one end of the support rod 2, a filter plate 4 fixedly connected to the inner wall of the treatment shell 1, an outer shell 5 fixedly connected to the top side wall of the treatment shell 1, a first opening 6 communicating with the inner wall of the bottom end of the outer shell 5 and the inner wall of the top end of the treatment shell 1, first grooves 7 symmetrically opened at both ends of the inner wall of the outer shell 5, first electric slide rails 8 fixedly connected to the inner wall of each of the first grooves 7, first sliding plates 9 slidably connected to the side walls of each of the two first electric slide rails 8, support plates 10 fixedly connected to the side walls of the two first sliding plates 9, a purification component 11 fixedly connected to the bottom side wall of the support plate 10, a blockage detection component 12 opened on the inner wall of the treatment shell 1, a blockage treatment component 13 fixedly connected to the inner wall of one end of the outer shell 5, and a dust collection component 14 opened on the inner wall of the bottom end of the outer shell 5.

[0030] In this embodiment, the purification component 11 includes multiple support springs 111 fixedly connected to the bottom side wall of the support plate 10. One end of each support spring 111 is fixedly connected to the same mounting frame 112. An activated carbon plate 113 is abutted against the inner wall of the mounting frame 112. Multiple second grooves 114 are symmetrically formed on the inner walls of both ends of the mounting frame 112 about the activated carbon plate 113. A first electric telescopic rod 115 is fixedly connected to the inner wall of one end of each second groove 114. A locking plate 116 is fixedly connected to the telescopic end of each first electric telescopic rod 115. The sidewalls of the clamping plate 116 all abut against the sidewalls of the activated carbon plate 113. When the activated carbon plate 113 needs to be replaced, the multiple first electric telescopic rods 115 are controlled to retract, so that the clamping plate 116 enters the second groove 114 without limiting the activated carbon plate 113. Then the activated carbon plate 113 is removed, and a new activated carbon plate 113 is placed between the second grooves 114. Then the first electric telescopic rods 115 are controlled to extend, and the clamping plate 116 is used to fix the new activated carbon plate 113, thus completing the replacement of the activated carbon plate 113.

[0031] A connecting ring 117 is fixedly connected to the top side wall of the mounting frame 112. Two slots 118 are symmetrically opened on the inner wall of the connecting ring 117. A second electric telescopic rod 119 is fixedly connected to the bottom side wall of the support plate 10. A side plate 1110 is fixedly connected to the telescopic end of the second electric telescopic rod 119. Two third electric telescopic rods 1111 are symmetrically fixedly connected to the two side walls of the side plate 1110. A limit plate 1112 is fixedly connected to the telescopic end of each of the third electric telescopic rods 1111. The limit plate 1112 is located inside the corresponding slot 118.

[0032] The blockage detection component 12 includes two third grooves 121 symmetrically opened on the inner wall of the processing shell 1. A fourth groove 122 communicating with the two third grooves 121 is opened on the inner wall of the top of the processing shell 1. The inner wall of each third groove 121 is fixedly connected to a second electric slide rail 123. The side wall of each second electric slide rail 123 is slidably connected to a second slide plate 124. The side wall of each of the two second slide plates 124 is fixedly connected to the same connecting plate 125 at one end. A fourth electric telescopic rod 126 is fixedly connected to one end of the side wall of the connecting plate 125.

[0033] The telescopic end of the fourth electric telescopic rod 126 is fixedly connected to a connecting block 127. Multiple pressure sensors 128 are fixedly connected to one side wall of the connecting block 127. The detection ends of the multiple pressure sensors 128 are all fixedly connected to detection springs 129. A detection plate 1210 is fixedly connected to one end of each detection spring 129.

[0034] Specifically, when it is necessary to purify indoor exhaust gas containing a large amount of dust, the detection plate 1210 and pressure sensor 128 can be used to detect whether the activated carbon plate 113 is blocked by dust. After detecting that the activated carbon plate 113 is blocked by a large amount of dust, the activated carbon plate 113 is moved into the outer shell 5. Then, the limiting plate 1112 is not fixed to the mounting frame 112 and the activated carbon plate 113. At this time, the mounting frame 112 and the activated carbon plate 113 can shake.

[0035] In this embodiment, the blockage treatment component 13 includes a vibration motor 131 fixedly connected to the inner wall of one end of the outer shell 5, a fifth electric telescopic rod 132 fixedly connected to the output end of the vibration motor 131, a vibration shell 133 fixedly connected to the telescopic end of the fifth electric telescopic rod 132, and a plurality of air outlet holes 134 opened on the side wall of the vibration shell 133.

[0036] Solenoid valves 135 are installed inside the air outlet 134. An air pump 136 is fixedly connected to the side wall of the vibrating shell 133. The air outlet of the air pump 136 extends inward through the side wall of the vibrating shell 133. Two base plates 137 are symmetrically fixedly connected to the inner wall of one end of the outer shell 5. The top side walls of the two base plates 137 are in contact with the bottom side wall of the vibrating shell 133.

[0037] The dust collection assembly 14 includes a fifth groove 141 on the inner wall of the bottom end of the outer shell 5, a water storage shell 142 fixedly connected to the inner wall of the top end of the outer shell 5, a plurality of through holes on the side wall of the bottom end of the water storage shell 142, and a nozzle 143 is provided inside each of the corresponding through holes. A water pump 144 is fixedly connected to the side wall of the water storage shell 142, the water outlet of the water pump 144 extends inward through the side wall of the water storage shell 142, and the water inlet of the water pump 144 is fixedly connected to a connecting pipe 145, and a filter screen 146 is provided at one end of the connecting pipe 145.

[0038] Specifically, the vibrating shell 133 drives the activated carbon plate 113 to vibrate, thereby discharging the dust adhering to one side of the activated carbon plate 113. The air outlet 134 can also blow out the dust clogging the inside of the activated carbon plate 113, thus cleaning the dust clogging the inside of the activated carbon plate 113. The nozzle 143 and water pump 144 can also dissolve the dust discharged from one side of the activated carbon plate 113 in water, which finally falls into the fifth groove 141, making it easy to collect the dust and preventing it from spreading everywhere. This avoids the need for staff to remove the activated carbon from the indoor exhaust gas treatment device and then clean the dust clogging the surface of the activated carbon, greatly improving the purification efficiency and reliability of the device when treating indoor exhaust gas.

[0039] The operating principle of the present invention is described as follows:

[0040] In this invention, when indoor exhaust gas needs to be purified, the exhaust fan 3 is activated to draw the indoor exhaust gas into the treatment shell 1. The indoor exhaust gas first passes through the filter screen 146 to remove large impurities. The filtered indoor exhaust gas then passes through the activated carbon plate 113, which purifies the indoor exhaust gas. Finally, it is discharged from the other end of the treatment shell 1, completing the purification of the indoor exhaust gas. When the indoor exhaust gas contains a large amount of dust, after the activated carbon plate 113 has purified the indoor exhaust gas for a period of time, the second electric slide rail 123 is activated, driving the second sliding plate 124 downward to move the connecting plate 125 out of the fourth groove 122. Then, the fourth electric telescopic rod 126 is activated, driving the connecting block 127 towards the activated carbon plate 113. The activated carbon plate 113 moves in three directions. Air flowing from the surface of the activated carbon plate 113 blows towards the detection plate 1210, which applies pressure to the detection spring 129. The corresponding pressure sensor 128 detects this pressure. If the pressure from the detection plate 1210 is too low, it indicates that one side of the activated carbon plate 113 is blocked by dust. The second electric slide rail 123 then moves the second sliding plate 124 downwards, allowing the detection plate 1210 to continue detecting other parts of the activated carbon plate 113. After completing the overall detection of the activated carbon plate 113, when the dust blockage exceeds half the surface area of ​​the activated carbon plate 113, the efficiency of the activated carbon plate 113 in purifying indoor exhaust gas is determined. Extremely low, then control the first electric slide rail 8 to start, driving the first slide plate 9 to move upward, causing the support plate 10 to drive the mounting frame 112 and activated carbon plate 113 to move upward, so that the activated carbon plate 113 is located inside the outer shell 5 and on one side of the vibrating shell 133. Then control the third electric telescopic rod 1111 to retract, driving the limiting plate 1112 to move, so that the limiting plate 1112 moves out of the slot 118. Then control the second electric telescopic rod 119 to start, driving the side plate 1110 to move upward. At this time, the support plate 10 and the mounting frame 112 are connected only by multiple support springs 111. Then control the first electric telescopic rod 115 on the side of the mounting frame 112 near the vibrating shell 133 to retract, driving the slot plate 116 towards the second groove 1. 14. After internal movement, the fifth electric telescopic rod 132 is activated, driving the vibrating shell 133 to move, so that the side wall of the vibrating shell 133 abuts against one side of the activated carbon plate 113. Then, the vibration motor 131 is activated, driving the vibrating shell 133 to vibrate. At this time, the vibrating shell 133 will drive the activated carbon plate 113 to vibrate. Under the action of vibration, the dust attached to the surface of the activated carbon plate 113 will fall off due to vibration. After the vibrating shell 133 vibrates the activated carbon plate 113 for a period of time, the vibration motor 131 is turned off. Then, the second electric telescopic rod 119 and the third electric telescopic rod 1111 are activated, so that the limiting plate 1112 re-enters the slot 118, and the limiting plate 1112 continues to fix the mounting frame 112.Then, the fifth electric telescopic rod 132 is activated, making the side wall of the vibrating shell 133 fully contact one side of the activated carbon plate 113. Next, the air pump 136 is activated, and simultaneously the solenoid valve 135 is opened, injecting air into the vibrating shell 133. This air is then blown onto the surface of the activated carbon plate 113 through the air outlet 134, causing the dust clogging the activated carbon plate 113 to be blown to the other side, thus completing the removal of the dust clogging the activated carbon plate 113. Afterward, the first electric slide rail 8 is activated, placing the cleaned activated carbon plate 113 back into the processing shell 1, facilitating the continued use of the activated carbon plate 113 to process indoor exhaust gases. During purification, while the vibrating housing 133 and air outlet 134 clean the dust clogging the inside of the activated carbon plate 113, the nozzle 143 and water pump 144 are simultaneously activated. The nozzle 143 sprays water from the water storage tank 142 downwards. At this time, the dust particles vibrated and blown out from one side of the activated carbon plate 113 are splashed by the water and dissolved, eventually falling into the fifth groove 141. Simultaneously, the water pump 144, through the connecting pipe 145, re-transports the water from the fifth groove 141 back into the water storage tank 142, allowing the nozzle 143 to continuously spray water. The filter screen 146 filters out the dust contained in the water, preventing the dust from being trapped. The activated carbon is pumped into the water storage shell 142 to collect the dust clogging inside the activated carbon plate 113. When indoor exhaust gas containing a large amount of dust needs purification, the detection plate 1210 and pressure sensor 128 detect whether the activated carbon plate 113 is clogged with dust. If a large amount of dust is detected inside the activated carbon plate 113, the activated carbon plate 113 is moved into the outer shell 5. Then, the limiting plate 1112 is not fixed to the mounting frame 112 and the activated carbon plate 113, allowing them to sway. The vibrating shell 133 then drives the activated carbon plate 113 to vibrate, thereby purifying the activated carbon. Dust adhering to one side of the activated carbon plate 113 is discharged, and dust clogging the inside of the activated carbon plate 113 can also be blown out through the air outlet 134, completing the cleaning of dust clogging the inside of the activated carbon plate 113. Furthermore, the dust discharged from one side of the activated carbon plate 113 can be dissolved in water using the nozzle 143 and water pump 144, finally falling into the fifth groove 141 for easy dust collection and to prevent dust from scattering. This eliminates the need for workers to remove the activated carbon from the indoor exhaust gas treatment device and clean the dust clogging its surface, greatly improving the purification efficiency and reliability of the device when treating indoor exhaust gas.
