Description

Technical Field

[0001] The present invention relates to the field of air purification equipment, and particularly to an environment-friendly air purification device for building renovation. Background Art

[0002] There are often a large number of cultural relics, historical sites, etc. with extremely high historical, cultural and artistic values in old building heritages and historical blocks. The polluted air generated during construction contains a large amount of pollutants such as particulate matter and harmful gases. These pollutants will settle on the surface of cultural relics, accelerating the corrosion, aging and other damage processes of cultural relics, posing a serious threat to the protection of cultural relics. Therefore, during the construction process, the purification of air is particularly important. Traditional air purifiers mainly rely on filter screens for filtration, which have a certain filtering effect on large particulate matter and some harmful gases. However, in the face of a large amount of high-concentration dust, complex harmful gases and humid air environment generated during construction, their purification efficiency and effect often cannot meet the requirements, and the filter screens are prone to clogging and need to be replaced frequently, increasing the use cost and maintenance workload. Some single-function air purification equipment, such as equipment with only dehumidification function or only capable of removing a certain specific harmful gas, cannot comprehensively solve the problem of multiple air pollutants generated during construction and cannot achieve comprehensive purification of air. Therefore, we propose an environment-friendly air purification device for building renovation to solve the above-mentioned problems. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. During the use of the present invention, water will enter the water tank in the middle of the machine body through the water inlet pipe. At this time, the submersible pump chamber can extract the water inside the water tank, and export it through the connecting pipe to the inside of the rotating frame and finally spray it out atomized through the atomizing nozzle, forming a "water mist circle" around the air purifier. At this time, when the surrounding air is drawn into the air purifier, the air will first contact the surrounding "water mist circle", and the "water mist circle" can quickly "reduce dust" the particulate matter in the air, realizing the separation of large particulate matter in the air and completing the preliminary purification of the air.

[0016] 2. The further filtration of the air can be realized through the intake air filter screen and the filter cloth cover inside the air purifier, so that the fine particulate matter can be further filtered and purified.

[0017] 3. During actual construction and renovation, people can adjust the adjusting frame according to the actual use environment and the degree of pollution in the air. By rotating the adjusting frame, it can cooperate with the convex ring on the outer periphery of the rotating ring to realize the adjustment of the height of the adjusting frame. When the adjusting frame is rotated downward, it will press the tail of the rotating frame, driving the whole rotating frame to deflect. When the adjusting frame is rotated upward, the resilience of the elastic member can support the tail of the rotating frame, so that the rotating frame and the atomizing nozzle can deflect in the opposite direction, thereby realizing the adjustment of the spraying direction of the rotating frame and further controlling the size of the "water mist circle".

[0018] 4. During actual use, the water inside the water tank will drip onto the diversion frame through the drip holes at the bottom of the dropper, and flow down through the downstream holes on the side of the diversion frame. The flowing water will be further guided to flow down through the diversion ring. The diversion groove on the diversion ring can realize the further guidance of the water flow, so that the water flow can form a water curtain on the surface of the filter cloth cover, realizing the washing of the incoming air and simultaneously washing the filter cloth cover, avoiding excessive dust intercepted on the surface of the filter cloth cover from affecting later use. The sewage will be discharged through the through holes at the bottom and converge into the bottom chamber, realizing the continuous use of the air purifier. Description of the Drawings

[0038] Working principle:

[0039] When carrying out protective renovation construction on old building heritage and historical blocks, people can use the air purifier 1 to purify the polluted air generated during indoor renovation construction. During construction, people can place the air purifier 1 in the construction area, connect the water inlet pipe 112 and the sewage pipe 110 to the water source and the sewage bucket respectively with connecting hoses, and then start the air purifier 1. Through the operation of the exhaust fan inside the top bin 114, the surrounding air can be extracted. The air will enter the air purifier 1 through the intake filter screen 109. During this process, water will enter the water tank in the middle of the body 101 through the water inlet pipe 112. At this time, the water in the water tank can be extracted through the submersible pump bin 126 and exported to the inside of the rotating frame 117 through the connecting pipe 120 and finally atomized and sprayed out through the atomizing nozzle 116, forming a "water mist circle" around the air purifier 1. At this time, when the surrounding air is drawn into the air purifier 1, the air will first come into contact with the surrounding "water mist circle". Through the "water mist circle", the particulate matter in the air can be quickly "dust-settled", realizing the separation of large particulate matter in the air and completing the preliminary purification of the air. Then, through the intake filter screen 109 and the filter cloth cover 127 inside the air purifier 1, the air can be further filtered, enabling the fine particulate matter to be further filtered and purified. Then the air will be sucked in by the air extraction head 132 and enter the air extraction pipe 130 through the air extraction cover 131. After the air enters the air extraction pipe 130, it will be discharged through the one-way valve on the outer periphery of the upper part of the air extraction pipe 130 and enter the water tank, coming into contact with the water in the water tank. Through the water in the water tank, the air can be washed and purified. Then, under the action of the air pump inside the top bin 114, the purified air will be extracted by the air intake cover 137 and discharged through the exhaust cover 113 to return to the outside world, realizing the complete purification cycle of the air, which is beneficial for actual use. During actual construction renovation, people can adjust the adjusting frame 115 according to the actual use environment and the degree of pollution in the air. By rotating the adjusting frame 115, it can cooperate with the convex ring 122 on the outer periphery of the rotating ring 121 to realize the adjustment of the height of the adjusting frame 115. When the adjusting frame 115 is rotated downward, it will press the tail of the rotating frame 117, driving the whole rotating frame 117 to deflect. When the adjusting frame 115 is rotated upward, the tail of the rotating frame 117 can be propped up by the resilience of the elastic member 118, enabling the rotating frame 117 and the atomizing nozzle 116 to deflect in the opposite direction, thereby realizing the adjustment of the spraying direction of the rotating frame 117 and being able to further control the size of the "water mist circle". During actual use, the water in the water tank will drip onto the guide frame 124 through the drip holes 136 at the bottom of the dropper 125 and flow downward through the downward flow holes 134 on the side of the guide frame 124. The flowing water will be guided to continue flowing downward through the guide ring 123. Through the guide grooves 133 on the guide ring 123, the flowing water can be further guided, enabling the flowing water to form a water curtain on the surface of the filter cloth cover 127 to realize the washing of the incoming air.Meanwhile, the filter cloth cover 127 can be washed with water to prevent excessive dust intercepted on the surface of the filter cloth cover 127 from affecting its later use. The sewage will be discharged through the through holes 129 at the bottom and converge inside the bottom bin 108, enabling the continuous use of the air purifier 1.
