Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a formaldehyde adsorption treatment device for building construction. Background Art

[0002] In modern construction, a large number of new building materials are widely used. Common new materials such as artificial boards, chemical adhesives and decorative coatings contain many formaldehyde components. These materials will continue to release formaldehyde during the construction process, causing the air quality of the construction site to seriously deteriorate. It also poses a huge threat to the health of construction workers. Therefore, formaldehyde adsorption treatment equipment is needed to improve the construction site environment during the construction process.

[0003] Existing formaldehyde adsorption treatment devices mainly use air suction devices to absorb the air at construction sites, and absorb formaldehyde in the air through the internal activated carbon plates, thereby improving the environment. However, there are the following shortcomings when used: 1. During the construction process, architectural coatings and paints are mainly used for interior and exterior wall decoration of buildings. In order to improve their performance, such as the hardness, flexibility and water resistance of the coating film, many coatings will add additives containing formaldehyde during the production process. These additives will gradually evaporate and release a large amount of formaldehyde during the drying process after the coating is applied. The activated carbon plates in the formaldehyde adsorption device have limited formaldehyde adsorption capacity. In order to ensure the formaldehyde adsorption effect, during the construction process, the activated carbon plates in the formaldehyde adsorption device must be used to absorb the formaldehyde in the air. 1. The activated carbon plates inside the construction process need to be replaced frequently, which is inconvenient to use; 2. During the construction process, the amount of formaldehyde released is large, and the activated carbon plates in the formaldehyde adsorption treatment device can only temporarily adsorb formaldehyde in the material. Over time, it will gradually become saturated, causing formaldehyde to be released into the construction environment again, causing secondary pollution. The treatment effect needs to be improved; 3. During the construction process, the dust particle content in the air is large. When the formaldehyde in the air is adsorbed, a large amount of dust particles flow into the device, causing pollution, blockage and even failure of the formaldehyde adsorption treatment device. Construction sites are very challenging for traditional formaldehyde adsorption treatment devices.

[0004] Therefore, a formaldehyde adsorption treatment device for construction is proposed to solve the problems raised in the above background technology. Summary of the invention

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described 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 creative work are within the scope of protection of the present invention.

[0041] Example 1: Please refer to Figure 1-Figure 10As shown, the present invention provides a technical solution: a formaldehyde adsorption treatment device for construction, comprising a treatment and collection component 1, an adsorption component 2 is installed on the top of the treatment and collection component 1, a separation component 3 is arranged on the top of the adsorption component 2, a driving component 4 and an exhaust component 5 are arranged inside the separation component 3, and a dust collection component 6 is arranged outside the separation component 3. The treatment and collection component 1 is used to treat formaldehyde, and comprises a bottom cylinder 101, a connecting channel 108 is fixedly connected to the top of the bottom cylinder 101, a titanium dioxide filter 109 and an ultraviolet lamp 110 are installed between the inner surface walls of the connecting channel 108, and the ultraviolet lamp 110 is located above the titanium dioxide filter 109. The attachment component 2 is used to absorb formaldehyde in the air, including a circular shell 201, the bottom of the circular shell 201 and the top of the connecting channel 108 are fixedly connected, an annular shell 203 is rotatably connected between the inner surface walls of the circular shell 201 through a bearing, and activated carbon plates 204 are inserted near the top and bottom of the annular shell 203. The separation component 3 is used to separate dust in the air, including an air intake channel 301, the bottom of the air intake channel 301 and the top of the circular shell 201 are fixedly connected, the driving component 4 includes a second motor 401, a first rotating shaft 402 and a second rotating shaft 405, the exhaust component 5 includes a mounting frame 501, and the dust collecting component 6 includes a separation shell 601.

[0042] The second motor 401 is fixedly mounted on the rear surface of the intake channel 301, the first rotating shaft 402 is rotatably connected to a position near the bottom between the front and rear inner walls of the intake channel 301, the second rotating shaft 405 is rotatably connected to a position near the bottom between the front and rear inner walls of the intake channel 301, the rear end of the first rotating shaft 402, the output end of the second motor 401 and the rear end of the first rotating shaft 402 are fixedly connected, the front ends of the first rotating shaft 402 and the second rotating shaft 405 both extend to the front side of the intake channel 301, the front end of the first rotating shaft 402 is fixedly connected to a first pulley 404, the front end of the second rotating shaft 405 is fixedly connected to a second pulley 406, a transmission belt 407 is arranged between the wheel grooves of the first pulley 404 and the second pulley 406, after the second motor 401 is started, it drives the first rotating shaft 402 to rotate, at this time, the first pulley 404 at the end of the first rotating shaft 402 cooperates with the second pulley 406 and the transmission belt 407 at the end of the second rotating shaft 405 to drive the second rotating shaft 405 to rotate.

[0043] The diameter of the first pulley 404 is smaller than the diameter of the second pulley 406. The outer surface of the second rotating shaft 405 is fixedly connected with the first bevel gear 408. The mounting frame 501 is fixedly connected between the inner surface walls of the air intake channel 301. The top of the mounting frame 501 is rotatably connected with the driving shaft 502 through a bearing. The bottom end of the driving shaft 502 is fixedly connected with the second bevel gear 503. The second bevel gear 503 and the first bevel gear 408 are meshed and connected. The top end of the driving shaft 502 is fixedly connected with the exhaust fan 504. The exhaust fan 504 is located below the first rotating shaft 402. The fan 504 is located above the second rotating shaft 405. Since the diameter of the first pulley 404 is smaller than the diameter of the second pulley 406, it has an acceleration effect, so that the rotation speed of the second rotating shaft 405 is higher than the rotation speed of the first rotating shaft 402. When the second rotating shaft 405 rotates, the first bevel gear 408 whose surface follows the rotation will drive the second bevel gear 503 to rotate synchronously. At this time, the second bevel gear 503 will drive the exhaust fan 504 to rotate through the driving shaft 502, thereby generating airflow and drawing the air in the construction site into the interior of the device from above the air inlet channel 301.

[0044] A heater 208 is installed near the bottom of the rear inner wall of the circular shell 201, and an arc plate 207 is fixedly connected to the rear inner wall of the circular shell 201 above the heater 208. A fixed cover 205 is fixedly installed at the front end of the annular shell 203, and an outer cover 202 is fixedly installed at the front end of the circular shell 201. A first motor 206 is fixedly installed on the front surface of the outer cover 202. The output end of the first motor 206 rotates through the outer surface of the outer cover 202 and extends to the other side. The output end of the first motor 206 is fixedly connected to the fixed cover 205. Under the action of the exhaust fan 504, formaldehyde in the air will be adsorbed into the micropores of the activated carbon plate 204 above the inside of the annular shell 203. At the same time, larger particulate impurities will be adsorbed on the surface of the activated carbon plate 204. When the first motor 206 is started The fixed cover 205 and the annular shell 203 can be driven to rotate 180°, so that the upper activated carbon plate 204 and the lower activated carbon plate 204 are interchanged in position, and the heater 208 is close to the lower activated carbon plate 204. After startup, it will convert electrical energy into thermal energy, and control the temperature at 150°C through the built-in controller. At this time, after the lower activated carbon plate 204 is heated and the temperature exceeds 80°C, as the temperature rises, the formaldehyde in the micropores of the activated carbon plate 204 will obtain enough energy to overcome the adsorption force of the activated carbon on it, thereby producing a desorption phenomenon, and under the action of the airflow, it flows toward the direction of the processing and collection component 1. The arc plate 207 can block the airflow inhaled from above to prevent the airflow from blowing directly to the heater 208, thereby causing a large amount of heat loss, which has an energy-saving effect.

[0045] The use steps of the present invention are as follows: during the construction process, when the air contains a large amount of formaldehyde due to construction materials, the device is placed at the construction site, and then the second motor 401 is started to drive the first rotating shaft 402 to rotate. At this time, under the action of the first pulley 404, the second pulley 406 and the transmission belt 407, the second rotating shaft 405 will rotate at a speed lower than the first rotating shaft 402, and the first bevel gear 408 on the surface of the second rotating shaft 405 cooperates with the second bevel gear 503 to drive the driving shaft 502 and the exhaust fan 504 to rotate, thereby the construction is completed. The air in the place is drawn into the device from the open top of the air inlet channel 301. When the air enters the circular shell 201 area, the formaldehyde in the air will be adsorbed by the activated carbon plate 204 on the upper part of the annular shell 203. After the adsorption time reaches the set value, the first motor 206 and the heater 208 are started. The first motor 206 drives the annular shell 203 to rotate 180 degrees through the fixed cover 205. At this time, the unsaturated activated carbon plate 204 at the bottom will rotate to the top to continue to adsorb formaldehyde, and the activated carbon plate 204 at the top will rotate to the bottom and continue to adsorb formaldehyde under the heating action of the heater 208. Under the action of airflow, formaldehyde and particulate impurities in the air will be separated in large quantities, thus solving the problem of limited formaldehyde adsorption capacity of activated carbon plate 204. It is not necessary to frequently replace activated carbon plate 204 during construction, thus improving the convenience of use. At the same time, formaldehyde desorbed in large quantities from the micropores of activated carbon plate 204 below will first pass through connecting channel 108 when flowing downward under the action of airflow. After the ultraviolet lamp 110 in connecting channel 108 is started, The titanium dioxide filter 109 is exposed to close-range irradiation, and the energy of ultraviolet photons can excite the titanium dioxide to produce a photocatalytic reaction. At this time, the formaldehyde molecules will be decomposed into carbon dioxide and water under the action of the photocatalyst, and the carbon dioxide will flow downward through the titanium dioxide filter 109 into the bottom tube 101, and finally be discharged from the exhaust hole 104, while the water decomposed from the formaldehyde will gather on the surface of the titanium dioxide filter 109 and drip downward under the action of gravity. After the formaldehyde is decomposed, the problem of secondary pollution is effectively solved, and the formaldehyde adsorption treatment effect in the construction environment is improved.

[0046] Embodiment 2: Figure 1-Figure 4As shown, the difference between the embodiment and the embodiment lies in that the outer surface of the bottom cylinder 101 is rotatably connected to the semicircular shell 102 near the bottom, the inner surface wall of the semicircular shell 102 is fixedly connected to the position near the bottom, and the collecting dish 106 is placed inside the fixed dish 105. The outer surface of the bottom cylinder 101 is located above the collecting dish 106 and is surrounded by a plurality of groups of exhaust holes 104. The inner surface wall of the bottom cylinder 101 is located above the exhaust holes 104 and is fixedly connected to a guide ring 107. A buckle 103 is provided between the outer surfaces of the bottom cylinder 101 and the semicircular shell 102. The buckle 103 is used to fix the semicircular shell 102 and the bottom cylinder 101. After opening the buckle 103, the semicircular shell 102 can be rotated outward, and the fixed dish 105 is fixed to the semicircular shell 102, and is mainly used to place the collecting dish 106.

[0047] The use steps of the present invention are as follows: due to the particularity of the construction site, the formaldehyde content therein is relatively high, so the water decomposed after a long period of treatment is not sufficient to be completely volatilized, thereby generating water droplets and dripping from the surface of the titanium dioxide filter 109. During the dripping process, the guide ring 107 plays a role of guiding the water, causing it to drip to a position near the middle of the bottom cylinder 101, and then enter the collection dish 106. After opening the buckle 103, the semicircular shell 102 can be rotated outward, and then the collection dish 106 in the fixed dish 105 can be taken out upward and the water can be poured out and then restored. The decomposed product can be easily handled, the structure is simple, and the practicality is high.

[0048] Embodiment 3: Figure 1-Figure 3 and Figure 6-Figure 10 As shown, the difference between the embodiment and the embodiment is that a filter plate 304 is rotatably connected to the inner wall on one side of the air inlet channel 301, and a connecting port 302 is opened on the inner wall on the other side of the air inlet channel 301. One side of the filter plate 304 extends to the outside of the connecting port 302. An impact block 403 is fixedly connected to the outer surface of the first rotating shaft 402. The impact block 403 and the filter plate 304 cooperate with each other. The filter plate 304 can effectively block large particles of dust in the construction site through the filter holes on the surface. The connecting port 302 is mainly used to connect the air inlet channel 301 and the inside of the separation shell 601. When the first rotating shaft 402 rotates rapidly under the action of the second motor 401, since the impact block 403 on the surface of the first rotating shaft 402 is shaped like a cam, it will repeatedly hit the bottom of the filter plate 304 during rotation, thereby causing it to vibrate at a high frequency.

[0049] Side grooves 303 are provided on the front and rear outer surfaces of the air inlet passage 301 near the connecting port 302, and sliders 305 are fixedly connected to the front and rear outer surfaces of the filter plate 304. The sliders 305 are slidably embedded between the inner walls of the side grooves 303, and a spring 306 is fixedly connected between the inner top of the side grooves 303 and the top of the slider 305. The side grooves 303 are mainly used to accommodate the sliders 305, and the sliders 305 and the side grooves 303 are arc-shaped as a whole, and the rotation point is consistent with the rotation point of the filter plate 304. The spring 306 provides downward pressure on the slider 305, so that the filter plate 304 can fall quickly when it rotates upward after being hit by the impact block 403.

[0050] The separation shell 601 is fixedly connected to the outer surface of one side of the air inlet channel 301, and the filter plate 304 extends to the interior of the separation shell 601. The front surface of the separation shell 601 is fixedly connected to a dust exhaust port 602 near the bottom. A hose 607 is fixedly installed at the front end of the dust exhaust port 602 through a clamp, and a cloth bag 608 is fixedly installed at the bottom end of the hose 607 through a clamp. The dust entering the separation shell 601 will enter the hose 607 through the dust exhaust port 602 and finally enter the interior of the cloth bag 608. The cloth bag 608 is a common item in construction sites. It has pores on its surface. It can trap dust while exhausting air. It is easy to obtain materials and can be directly packaged after being filled with dust. It has low cost and good use effect.

[0051] A fixing frame 603 is fixedly connected between the inner walls of the dust exhaust port 602, and a third rotating shaft 604 is rotatably connected to the inner wall of the rear side of the separation shell 601 near the bottom. The front end of the third rotating shaft 604 rotates through the rear surface of the fixing frame 603 and extends to the front side. A fan blade 606 is fixedly connected to the front end of the third rotating shaft 604. When the fan blade 606 rotates, an airflow is generated inside the separation shell 601, so that the dust entering can be discharged into the cloth bag 608 at the bottom of the hose 607 along the airflow. The fixing frame 603 is used to support the third rotating shaft 604 to make it more stable when rotating.

[0052] The rear end of the third rotating shaft 604 is fixedly connected to the second pulley 605, and the rear end of the second rotating shaft 405 is fixedly connected to the first pulley 409. A transmission belt 410 is arranged between the outer surfaces of the first pulley 409 and the second pulley 605. The diameters of the first pulley 409 and the second pulley 605 are equal. During the rotation of the second rotating shaft 405, the first pulley 409 at its rear end cooperates with the second pulley 605 and the transmission belt 410 to drive the third rotating shaft 604 to rotate, thereby driving the fan blades 606 to rotate. No additional power source is required, which has the effect of energy saving and emission reduction.

[0053] The use steps of the present invention are as follows: after the air in the construction environment enters the air inlet channel 301, under the action of the airflow, the air containing formaldehyde and small particles of impurities will flow downward through the filter holes on the surface of the filter plate 304, while the larger particles of dust impurities in the air will be retained on the upper surface of the filter plate 304. When the second motor 401 drives the first rotating shaft 402 to rotate rapidly, the impact block 403 on the surface of the first rotating shaft 402 will repeatedly impact the bottom of the filter plate 304, and the spring 306 in the side groove 303 will continuously generate downward pressure on the slider 305 on the side of the filter plate 304, so that the filter plate 304 will generate high-frequency vibration during the impact process, and the filter plate 304 will tilt as a whole. Therefore, under the action of vibration and gravity, the large particles of dust on the surface of the filter plate 304 will gradually slide down and finally enter the separation shell 601 on the side. During the rotation of the second rotating shaft 405, the first pulley 409 at its rear end cooperates with the second pulley 605 and the transmission belt 410 to drive the third rotating shaft 604 to rotate, thereby driving the fan blades 606 to rotate. When the fan blades 606 rotate, airflow will be generated inside the separation shell 601, so that the incoming dust can be discharged into the cloth bag 608 at the bottom of the hose 607 along the airflow, thereby solving the problem that a large amount of dust particles in the construction environment can easily pollute, block or even cause device failure to the formaldehyde adsorption device. In addition, no additional power source is required during the dust treatment process. At the same time, the cloth bag 608 is a common item in construction sites. It has pores on the surface. It can trap dust while allowing air to be discharged. It is easy to obtain materials and can be directly packaged and processed after being filled with dust. It has low cost and good use effect.
