Description

Technical Field

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

[0002] After building construction, a large amount of formaldehyde will remain indoors. When formaldehyde is released into the indoor air, it will pose a very serious hazard to human health. Therefore, whether the formaldehyde in the room exceeds the standard after building construction is an important detection item after building construction. If the formaldehyde exceeds the standard, ventilation or intervention treatment is required. Formaldehyde mainly comes from kitchen cabinets, floors, and wall painting components, etc. Generally, formaldehyde cleaning equipment is placed in a relatively large indoor environment and uses the method of air extraction and exhaust to accelerate the emission speed of indoor formaldehyde. However, high-concentration formaldehyde actually exists in the narrow space of the kitchen cabinet. Only by opening the cabinet door to let the air out on its own, the purification efficiency is relatively low. Summary of the Invention

[0003] In order to solve the above problems and improve the emission efficiency of formaldehyde in the kitchen cabinet, the present invention provides the following technical solutions:

[0004] A formaldehyde adsorption and treatment device for building construction, including an outer cover. A front cover is installed at the front end of the outer cover. A spring extending backward into the outer cover is installed inside the front cover. A self-adjusting plate is fixed to the rear end of the spring. Assembly holes communicating with each other are opened on both sides of the outer cover. Bearings are installed in the two assembly holes. A rotating shaft is fixed between the two bearings. A self-adjusting wheel is installed on the rotating shaft. The self-adjusting wheel is located behind the self-adjusting plate and forms a loading space with the self-adjusting plate. Purification pipes penetrate through the upper and lower sides of the outer cover. The front end of the purification pipe penetrates outside the front cover. The rear end of the purification pipe sequentially passes through the self-adjusting plate and the loading space and penetrates outside the rear end of the outer cover. Suction holes are opened on the part of the purification pipe penetrating into the loading space. Formaldehyde adsorption particles are loaded in the loading space. The formaldehyde adsorption particles are located on the front and rear sides of the self-adjusting wheel, and the formaldehyde adsorption particles cover the self-adjusting wheel in the loading space. A toothed belt is fixed to the self-adjusting plate. Tooth surfaces are provided on the edges of the self-adjusting plate. The toothed belt meshes with the tooth surfaces. When the self-adjusting plate moves backward due to the dilution and reduction of the aldehyde adsorption particles in the loading space, the self-adjusting wheel is driven to rotate by the toothed belt meshing with the tooth surfaces. A material distribution plate is fixed to the rear part of the bottom side of the loading space. The material distribution plate is located behind the self-adjusting wheel. The front end of the material distribution plate extends to be close to the lower rear side of the self-adjusting wheel. The front side of the material distribution plate slopes downward towards the bottom of the loading space.

[0005] Further preferably, a cylindrical part is provided at the front end of the outer cover, and the edge of the self-adjusting plate slides on the inner wall of the cylindrical part.

[0006] Further preferably, a conical portion is provided at the rear end of the outer cover, a suction cup is installed at the rear end of the conical portion, and the rear end of the purification pipe passes through the conical portion to the outside of the outer cover.

[0007] Further preferably, an air pump is provided on the outside of the outer cover, and the air outlet of the air pump is connected to the two purification pipes through a pipe joint.

[0008] Further preferably, the two purification pipes pass through the upper and lower sides of the self-adjusting wheel. A number of mesh holes are provided on the two purification pipes. A bending portion penetrating outside the conical portion is provided at the position where the two purification pipes pass through the self-adjusting wheel. A part of the mesh holes is arranged on the bending portion, and the other part of the mesh holes is arranged along the purification pipe to approach the self-adjusting plate.

[0009] Further preferably, self-adjusting shafts are fixed on both sides of the self-adjusting wheel. There are several self-adjusting shafts, and the several self-adjusting shafts are circumferentially arranged around the self-adjusting wheel. A self-adjusting gap is left between every two adjacent self-adjusting shafts. The diameter of the circle where all the self-adjusting shafts are located is smaller than the diameter of the tooth surface. The front end of the material distribution plate is close to the self-adjusting shaft, and a release gap is left between the material distribution plate and the self-adjusting shaft. Liberation spaces symmetrically located on the left and right sides of the self-adjusting wheel are formed inside all the self-adjusting shafts. When the self-adjusting wheel drives the self-adjusting shafts to rotate, the formaldehyde adsorption particles on the material distribution plate sequentially pass through the release gap and the self-adjusting gap and enter the liberation space, and with the continuous dilution effect, the aldehyde adsorption particles pass through the self-adjusting gap and fall into the front space of the loading space.

[0010] Further preferably, a baffle is fixed in the bottom space of the conical portion, and the top end of the baffle is connected to the front end of the material distribution plate.

[0011] Further preferably, the material distribution plate is a curved arc plate. The purification pipe at the bottom side reaches the material distribution plate. The bending portion on the purification pipe is in the same bending direction as the material distribution plate, and a movement space is formed between the bending of the purification pipe and the material distribution plate. The movement space gradually extends vertically downward, and the free end of the toothed belt enters the movement space.

[0012] The beneficial effects of the present invention compared with the prior art are:

[0013] During the purification process, these formaldehyde adsorption particles close to the suction holes and mesh holes are preferentially diluted and become smaller. Finally, they are completely diluted into the purification tube. The number of formaldehyde adsorption particles decreases, and due to the decrease, the formaldehyde adsorption particles become loose. At this time, the spring releases its length and provides a thrust to the self-adjusting plate. The self-adjusting plate provides pressure to the formaldehyde adsorption particles and eliminates the looseness between the formaldehyde adsorption particles, causing the outer formaldehyde adsorption particles to approach the suction holes and mesh holes again. The purification tube continues to intake and exhaust air, and continues to dilute the formaldehyde adsorption particles through the suction holes. The diluted carbon particles continue to enter the purification tube, continue to purify the formaldehyde air, and then are discharged from the purification tube. When this part of the formaldehyde adsorption particles is completely diluted, the tightness between the formaldehyde adsorption particles becomes loose again, the spring releases its length again, the self-adjusting plate moves again, and the formaldehyde adsorption particles are pressed tightly again, lifting the next-level formaldehyde adsorption particles to the positions of the suction holes and mesh holes. Repeat the above purification process. The formaldehyde adsorption particles are applied in stages. For treating formaldehyde gas in a narrow space, it is not only convenient for installation and use, but also this purification structure can fully meet the requirements, with a relatively low purification cost, and can quickly purify the formaldehyde component in the narrow space, improving the purification efficiency.

[0022] The following combines the accompanying drawings to clearly and completely describe the above and other embodiments and advantages of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all embodiments.

[0023] In one embodiment, as Figures 1-7 shown: This embodiment provides a formaldehyde adsorption treatment device for building construction, including an outer cover 1. The front end of the outer cover 1 is installed (damping lock) with a front cover 2. A spring 3 extending backward into the outer cover 1 is installed inside the front cover 2. The rear end of the spring 3 is fixed with a self-adjusting plate 4. The two sides of the outer cover 1 are provided with interconnected assembly holes 5. Two bearings 6 are installed in the two assembly holes 5. A rotating shaft 7 is fixed between the two bearings 6. A self-adjusting wheel 8 is installed on the rotating shaft 7. The self-adjusting wheel 8 is located behind the self-adjusting plate 4 and forms a loading space 9 with the self-adjusting plate 4. The upper and lower sides of the outer cover 1 are penetrated by a purification pipe 10. The front end of the purification pipe 10 penetrates outside the front cover 2. The rear end of the purification pipe 10 sequentially passes through the self-adjusting plate 4 and the loading space 9 and penetrates outside the rear end of the outer cover 1. The part of the purification pipe 10 penetrating into the loading space 9 is provided with suction holes 11. Formaldehyde adsorption particles are installed in the loading space 9. The formaldehyde adsorption particles are located on the front and rear sides of the self-adjusting wheel 8, and the formaldehyde adsorption particles cover the self-adjusting wheel 8 in the loading space 9. A tooth belt 12 is fixed on the self-adjusting plate 4. A tooth surface 13 is provided on the edge of the self-adjusting plate 4. The tooth belt 12 is engaged on the tooth surface 13. When the self-adjusting plate 4 moves backward due to the dilution and reduction of the aldehyde adsorption particles in the loading space 9, the self-adjusting wheel 8 is driven to rotate by the engagement of the tooth belt 12 on the tooth surface 13. A material distributing plate 14 is fixed at the rear and bottom side of the loading space 9. The material distributing plate 14 is located behind the self-adjusting wheel 8. The front end of the material distributing plate 14 extends to be close to the lower rear side of the self-adjusting wheel 8. The front side of the material distributing plate 14 slopes downward towards the bottom of the loading space 9.

[0024] A cylindrical part 15 is provided at the front end of the outer cover 1. The edge of the self-adjusting plate 4 slides on the inner wall of the cylindrical part 15. A conical part 16 is provided at the rear end of the outer cover 1. A suction cup 17 is installed at the rear end of the conical part 16. The rear end of the purification pipe 10 penetrates outside the outer cover 1 through the conical part 16. The conical part 16 makes the rear space of the loading space 9 larger, so that more formaldehyde adsorption particles can be stored.

[0025] AsFigure 7 As shown, an air pump is provided on the outer side of the outer cover 1, and the air outlet of the air pump is connected to the two purification pipes 10 through a pipe joint. The air pump does not simply refer to the air pump itself, and can also be replaced by a blower.

[0026] The two purification pipes 10 pass through the upper and lower sides of the self-adjusting wheel 8. A number of mesh holes 18 are provided on the two purification pipes 10. A bending portion 19 that penetrates outside the conical portion 16 is provided at the position of the two purification pipes 10 passing through the self-adjusting wheel 8. A part of the mesh holes 18 is provided on the bending portion 19, and the other part of the mesh holes 18 is arranged along the purification pipe 10 to be close to the self-adjusting plate 4.

[0027] Self-adjusting shafts 20 are fixed on both sides of the self-adjusting wheel 8. There are several self-adjusting shafts 20, and the several self-adjusting shafts 20 are arranged in a circumferential array around the self-adjusting wheel 8. A self-adjusting gap 21 is left between every two adjacent self-adjusting shafts 20. The diameter of the circle where all the self-adjusting shafts 20 are located is smaller than the diameter of the tooth surface 13. The front end of the material distribution plate 14 is close to the self-adjusting shaft 20, and a release gap 22 is left between the material distribution plate 14 and the self-adjusting shaft 20. Liberation spaces 23 that are symmetric on the left and right sides of the self-adjusting wheel 8 are formed inside all the self-adjusting shafts 20. When the self-adjusting wheel 8 drives the self-adjusting shafts 20 to rotate, the formaldehyde adsorption particles on the material distribution plate 14 sequentially pass through the release gap 22 and the self-adjusting gap 21 and enter the liberation space 23, and with the continuous dilution effect, the aldehyde adsorption particles pass through the self-adjusting gap 21 and fall into the front space of the loading space 9.

[0028] A baffle 24 is fixed in the bottom space of the conical portion 16, and the top end of the baffle 24 is connected to the front end of the material distribution plate 14. The material distribution plate 14 is a curved arc plate. The bottom purification pipe 10 reaches the material distribution plate 14. The bending portion 19 on the purification pipe 10 is in the same bending direction as the material distribution plate 14, and a movement space 25 is formed between the bending of the purification pipe 10 and the material distribution plate 14. The movement space 25 gradually extends vertically downward. The free end of the toothed belt 12 enters the movement space 25. The movement space 25 is used to increase the movement stroke of the toothed belt 12 and orient the toothed belt 12 to ensure the smooth movement of the toothed belt 12.

[0029] Working principle and effect: Remove the front cover 2 from the outer cover 1. The front cover 2 takes the spring 3, and the spring 3 takes the self-adjusting plate 4 to be removed from the outer cover 1 together. Load the formaldehyde adsorption particles into the loading space 9 through the end of the outer cover 1. Then reinstall the front cover 2 and the above components onto the front end of the outer cover 1. At this time, the formaldehyde adsorption particles are restricted between the self-adjusting plate 4 and the loading space 9. Some formaldehyde adsorption particles will also bury the self-adjusting wheel 8 in the loading space 9, and at the same time cover the mesh holes 18 on the two purification pipes 10. Some formaldehyde adsorption particles fall on the material distribution plate 14, and the part of the formaldehyde adsorption particles that bury the self-adjusting wheel 8 is restricted on the periphery of the liberation space 23 by the adjusting shaft 20. Press the front cover 2 forcefully to lock it on the outer cover 1. The locking force is transmitted to the self-adjusting plate 4 through the spring 3, and then transmitted from the self-adjusting plate 4 to the formaldehyde adsorption particles, making the formaldehyde adsorption particles close tightly to each other. Use the suction cup 17 to adsorb the whole device in the cabinet. Start the air pump (or fan), and inhale the formaldehyde-containing gas in the cabinet into the two purification pipes 10 through the air inlet. The purification particles in the formaldehyde adsorption particles are released outward, and enter the two purification pipes 10 through the suction holes 11 and the mesh holes 18. After mixing with the formaldehyde gas in the purification pipes 10, it is discharged from the front end of the purification pipes 10. The purification particles in the formaldehyde adsorption particles (such as activated carbon particles are released when the particles are activated carbon) are released into the purification pipes 10, and the formaldehyde gas is purified and discharged into the indoor air. Place the device in a narrow space and treat the formaldehyde gas in the narrow space, thereby improving the purification efficiency. During the purification process, these formaldehyde adsorption particles close to the suction holes 11 and the mesh holes 18 are preferentially diluted and become smaller, and finally completely diluted into the purification pipes 10. The formaldehyde adsorption particles become fewer, and the formaldehyde adsorption particles become loose due to the decrease. At this time, the spring 3 releases its length and provides a thrust to the self-adjusting plate 4. The self-adjusting plate 4 provides a pressure to the formaldehyde adsorption particles, and the looseness between the formaldehyde adsorption particles disappears, making the outer formaldehyde adsorption particles close to the suction holes 11 and the mesh holes 18 again. The purification pipes 10 continue to intake and exhaust air, continue to dilute the formaldehyde adsorption particles through the suction holes 11, and the diluted carbon particles continue to enter the purification pipes 10. The formaldehyde air is continuously purified and then discharged from the purification pipes 10. When this part of the formaldehyde adsorption particles is completely diluted, the tightness between the formaldehyde adsorption particles becomes loose again, the spring 3 releases its length again, the self-adjusting plate 4 moves again, and the formaldehyde adsorption particles are pressed tightly again. Repeat the above actions to lift the next level of formaldehyde adsorption particles to the positions of the suction holes 11 and the mesh holes 18, and repeat the above purification process.

[0030] From the above principle, it can be seen that the formaldehyde adsorption particles are applied in stages. This structural method is not only convenient for installation and use for treating formaldehyde gas in a narrow space, but also the purification structure can fully meet the requirements, with a relatively low purification cost. To provide the next level of formaldehyde adsorption particles to the purification pipes 10, no manual labor is required, and there is no need to set up power components to drive the self-adjusting plate 4 to move, so the manufacturing cost of the device is low.

[0031] In addition, when the self-adjusting plate 4 pushes the formaldehyde adsorption particles, it will also push the toothed belt 12. The toothed belt 12 is threaded through the formaldehyde adsorption particles and meshes with the tooth surface 13 of the self-adjusting wheel 8. The toothed belt 12 is made of spring steel and has a certain hardness. Therefore, the toothed belt 12 will drive the self-adjusting wheel 8 to rotate by pushing and meshing with the tooth surface 13. The self-adjusting wheel 8 drives the self-adjusting shafts 20 on both the left and right sides to rotate. Some of the formaldehyde adsorption particles adhere to the self-adjusting shafts 20 and fall into the self-adjusting gap 21 between two adjacent self-adjusting shafts 20. Driven by the rotation of the self-adjusting shafts 20, these formaldehyde adsorption particles change positions, improving the loosening effect, causing the formaldehyde adsorption particles that are being diluted and becoming smaller to change positions in advance, or passing through the self-adjusting gap 21 and falling into the liberation space 23. As the self-adjusting wheel 8 rotates, the self-adjusting shafts 20 send the large-particle formaldehyde adsorption particles to the positions of the suction holes 11 and the mesh holes 18 of the purification tube 10 in advance, ensuring that the suction holes 11 and the mesh holes 18 preferentially receive the diluted components of the formaldehyde adsorption particles in the first place, making the purification structure more reasonable.

[0032] It should be further noted that the purification tube 10 is not limited to being a round tube. The purification tube 10 can also be a flat tube. The suction holes 11 and the mesh holes 18 are distributed in the width direction of the flat tube, thereby increasing the contact area with the formaldehyde adsorption particles. The formaldehyde adsorption particles dilute the carbon particles into the purification tube 10 through more suction holes 11 and mesh holes 18. Not only is the utilization rate of the formaldehyde adsorption particles improved, but also the purification efficiency is enhanced.
