Description

Technical Field

[0001] This invention relates to the field of formaldehyde treatment technology, and in particular to a formaldehyde adsorption treatment device for building construction. Background Technology

[0002] After construction, a large amount of formaldehyde remains indoors. This formaldehyde, released into the air, poses a serious threat to human health. Therefore, whether indoor formaldehyde levels exceed the standard is a crucial post-construction test. If the formaldehyde level is too high, ventilation or intervention is necessary. Formaldehyde mainly comes from kitchen cabinets, flooring, and wall paint components. Typical formaldehyde removal equipment is usually placed in a larger indoor environment, using exhaust ventilation to accelerate formaldehyde removal. However, high concentrations of formaldehyde often exist in the confined space of kitchen cabinets, and simply opening cabinet doors for natural ventilation is inefficient. Summary of the Invention

[0003] To address the aforementioned problems and improve the formaldehyde emission efficiency within kitchen cabinets, this invention provides the following technical solution:

[0004] A formaldehyde adsorption and treatment device for building construction includes an outer casing. A front cover is installed at the front end of the outer casing. A spring extending rearward into the outer casing is installed inside the front cover. A self-adjusting plate is fixed to the rear end of the spring. Intersecting assembly holes are provided on both sides of the outer casing. 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 tubes extend through the upper and lower sides of the outer casing. The front end of each purification tube extends beyond the front cover, and the rear end of each purification tube passes through the self-adjusting plate and the loading space to extend beyond the rear end of the outer casing. The portion of the purification tube extending into the loading space... The self-adjusting wheel is provided with suction holes. Formaldehyde adsorption particles are contained in the filling space. The formaldehyde adsorption particles are located on the front and rear sides of the self-adjusting wheel and cover the self-adjusting wheel in the filling space. A toothed belt is fixed on the self-adjusting plate. The edge of the self-adjusting plate has toothed surfaces. The toothed belt engages with the toothed surfaces. When the self-adjusting plate moves backward due to the dilution and shrinkage of the formaldehyde adsorption particles in the filling space, the toothed belt engages with the toothed surfaces to drive the self-adjusting wheel to rotate. A distribution plate is fixed to the rear side of the bottom of the filling space. The distribution plate is located behind the self-adjusting wheel. The front end of the distribution plate extends to near the rear side below the self-adjusting wheel. The front side of the distribution plate slopes downward toward the bottom of the filling space.

[0005] More preferably, the front end of the outer cover is provided with a cylindrical portion, and the edge of the self-adjusting plate slides on the cavity wall of the cylindrical portion.

[0006] More preferably, the rear end of the outer cover is provided with a tapered portion, and a suction cup is installed at the rear end of the tapered portion, and the rear end of the purification tube extends through the tapered portion to the outside of the outer cover.

[0007] More 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] More preferably, the two purification tubes pass through the upper and lower sides of the self-adjusting wheel, and the two purification tubes are provided with a plurality of mesh holes. The two purification tubes are provided with a curved portion that extends beyond the conical portion at the position where they pass through the self-adjusting wheel. A part of the mesh hole is provided on the curved portion, and another part of the mesh hole extends along the arrangement of the purification tube to near the self-adjusting plate.

[0009] More preferably, self-adjusting shafts are fixed on both sides of the self-adjusting wheel, and there are several self-adjusting shafts arranged in a circumferential array around the self-adjusting wheel. A self-adjusting gap is left between each pair of adjacent self-adjusting shafts. The circumference diameter of all the self-adjusting shafts is smaller than the diameter of the tooth surface. The front end of the distribution plate is close to the self-adjusting shafts and a release gap is left between them. The inner side of all the self-adjusting shafts forms a symmetrical release space on the left and right sides of the self-adjusting wheel. When the self-adjusting wheel rotates with the self-adjusting shafts, the formaldehyde adsorption particles on the distribution plate pass through the release gap and the self-adjusting gap in sequence and enter the release space. With the continued dilution effect, the formaldehyde adsorption particles pass through the self-adjusting gap and fall into the front space of the loading space.

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

[0011] More preferably, the material distribution plate is a curved arc plate, the purification pipe on the bottom side reaches the material distribution plate, the curved part of the purification pipe is consistent with the bending direction of the material distribution plate, and a movement space is formed between the curved part of the material distribution plate and the bending part of the material distribution plate. The movement space gradually moves downward vertically, and the free end of the toothed belt enters the movement space.

[0012] The advantages of this invention compared to the prior art are:

[0013] During the purification process, the formaldehyde adsorption particles close to the suction holes and mesh openings are preferentially diluted and reduced in size, eventually becoming completely diluted into the purification tube. As the number of formaldehyde adsorption particles decreases, they become loose. At this point, the spring releases its length and provides a pushing force to the self-adjusting plate, which then applies pressure to the formaldehyde adsorption particles, eliminating the loosening between them. This allows the outer layer of formaldehyde adsorption particles to once again approach the suction holes and mesh openings. The purification tube continues to intake and exhaust air, continuing to dilute the formaldehyde adsorption particles through the suction holes. The diluted carbon particles continue to enter the purification tube, further purifying the formaldehyde-laden air before it is discharged from the purification system. The tube continues to discharge, and once the formaldehyde adsorption particles are diluted, the compactness between them loosens again, the spring releases its length, the self-adjusting plate moves again, and the formaldehyde adsorption particles are compressed again, lifting the next level of formaldehyde adsorption particles to the positions of the suction holes and mesh. The above purification process is repeated, and the formaldehyde adsorption particles are applied in stages. For treating formaldehyde gas in confined spaces, this method is not only easy to install and use, but also fully meets the requirements, has a low purification cost, and can quickly purify formaldehyde components in confined spaces, thus improving purification efficiency.

[0022] The above and other embodiments and advantages of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] In one implementation, such as Figures 1-7 As shown: This embodiment provides a formaldehyde adsorption treatment device for building construction, including an outer cover 1. A front cover 2 is installed (damped and locked) at the front end of the outer cover 1. A spring 3 extending rearward into the outer cover 1 is installed inside the front cover 2. A self-adjusting plate 4 is fixed to the rear end of the spring 3. Interconnected assembly holes 5 are opened on both sides of the outer cover 1. 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 between itself and the self-adjusting plate 4. Purification pipes 10 pass through the upper and lower sides of the outer cover 1. The front end of the purification pipe 10 extends beyond the front cover 2, and the rear end of the purification pipe 10 passes through the self-adjusting plate 4 and the loading space 9 to the rear end of the outer cover 1. Suction holes 11 are provided on the portion of the filling space 9. The filling space 9 is filled with formaldehyde adsorption particles. 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 filling space 9. A toothed belt 12 is fixed on the self-adjusting plate 4. The edge of the self-adjusting plate 4 is provided with toothed surfaces 13. The toothed belt 12 meshes with the toothed surfaces 13. When the self-adjusting plate 4 moves backward due to the dilution and shrinkage of the formaldehyde adsorption particles in the filling space 9, the self-adjusting wheel 8 is driven to rotate through the meshing of the toothed surfaces 13 by the toothed belt 12. A distribution plate 14 is fixed on the rear side of the bottom of the filling space 9. The distribution plate 14 is located on the rear side of the self-adjusting wheel 8. The front end of the distribution plate 14 extends to near the rear side of the self-adjusting wheel 8 and the front side of the distribution plate 14 is inclined downward toward the bottom of the filling space 9.

[0024] The outer cover 1 has a cylindrical portion 15 at its front end, and the edge of the self-adjusting plate 4 slides on the cavity wall of the cylindrical portion 15. The outer cover 1 has a conical portion 16 at its rear end, and a suction cup 17 is installed at the rear end of the conical portion 16. The rear end of the purification tube 10 extends through the conical portion 16 to the outside of the outer cover 1. The conical portion 16 increases the rear space of the filling space 9, thereby allowing more formaldehyde adsorption particles to be stored.

[0025] like Figure 7 As shown, an air pump is installed on the outside of the outer casing 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; it can also be replaced by a fan.

[0026] Two purification tubes 10 pass through the upper and lower sides of the self-adjusting wheel 8. Several mesh holes 18 are provided on the two purification tubes 10. A curved part 19 is provided at the position of the two purification tubes 10 passing through the self-adjusting wheel 8, extending beyond the conical part 16. A part of the mesh hole 18 is provided on the curved part 19, and another part of the mesh hole 18 is arranged along the purification tube 10 to approach 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 arranged in a circumferential array around the self-adjusting wheel 8. A self-adjusting gap 21 is left between each pair of adjacent self-adjusting shafts 20. The circumference diameter of all self-adjusting shafts 20 is smaller than the diameter of the tooth surface 13. The front end of the distribution plate 14 is close to the self-adjusting shafts 20 and a release gap 22 is left between it and the self-adjusting shafts 20. The inner side of all self-adjusting shafts 20 forms symmetrical release spaces 23 on the left and right sides of the self-adjusting wheel 8. When the self-adjusting wheel 8 rotates with the self-adjusting shafts 20, the formaldehyde adsorption particles on the distribution plate 14 pass through the release gap 22 and the self-adjusting gap 21 in sequence and enter the release space 23. With the continued dilution effect, the formaldehyde 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 part 16, and the top of the baffle 24 is connected to the front end of the distribution plate 14. The distribution plate 14 is a curved arc plate. The purification pipe 10 on the bottom side reaches the distribution plate 14. The bending direction of the purification pipe 10 and the upper bending part 19 is consistent with that of the distribution plate 14, and a movement space 25 is formed between them. The movement space 25 gradually moves downward vertically, and 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 to orient the toothed belt 12 to ensure smooth movement of the toothed belt 12.

[0029] Working principle and effect: The front cover 2 is removed from the outer cover 1. The front cover 2, along with the spring 3, and the spring 3, along with the self-adjusting plate 4, are removed from the outer cover 1. The formaldehyde adsorption particles are loaded into the loading space 9 through the end of the outer cover 1. Then, the front cover 2 and the above components are put back onto the front end of the outer cover 1. At this time, the formaldehyde adsorption particles are confined 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 18 on the two purification tubes 10. Some formaldehyde adsorption particles fall onto the distribution plate 14. The formaldehyde adsorption particles that bury the self-adjusting wheel 8 are confined to the periphery of the release space 23 by the adjusting shaft 20. Press the front cover 2 firmly to lock it onto the outer cover 1. The locking force is transmitted to the self-adjusting plate 4 through the spring 3, and then to the formaldehyde adsorption particles through the self-adjusting plate 4, so that the formaldehyde adsorption particles are tightly packed together. The entire device is attached to the cabinet using suction cup 17. The air pump (or fan) is turned on, and the formaldehyde-containing gas in the cabinet is drawn into the two purification tubes 10 through the air inlet. The purification particles in the formaldehyde adsorption granules are released outward and enter the two purification tubes 10 through the suction hole 11 and the mesh 18. After mixing with the formaldehyde gas in the purification tubes 10, the mixture is discharged from the front end of the purification tubes 10. The purification particles in the formaldehyde adsorption granules (if the particles are activated carbon, activated carbon particles are released) are released into the purification tubes 10, and the formaldehyde gas is purified and discharged into the indoor air. Placing the device in a small space and treating the formaldehyde gas in the small space improves the purification efficiency. During the purification process, the formaldehyde adsorption particles close to the suction holes 11 and mesh 18 are preferentially diluted and reduced in size, eventually becoming completely diluted into the purification tube 10. As the number of formaldehyde adsorption particles decreases, they become loose. At this point, the spring 3 releases its length and provides a push to the self-adjusting plate 4, which in turn applies pressure to the formaldehyde adsorption particles, eliminating the looseness between them. This allows the outer layer of formaldehyde adsorption particles to approach the suction holes 11 and mesh 18 again. The purification tube 10 continues to intake and exhaust air, continuing to dilute the formaldehyde adsorption particles through the suction holes 11. The diluted carbon particles continue to enter the purification tube 10, further purifying the formaldehyde-laden air before being discharged from the purification tube 10. Once this portion of the formaldehyde adsorption particles has been completely diluted, the compactness between the particles loosens again. The spring 3 releases its length again, the self-adjusting plate 4 moves again, and the formaldehyde adsorption particles are compressed again. This process is repeated to lift the next layer of formaldehyde adsorption particles to the positions of the suction holes 11 and mesh 18, and the purification process is repeated.

[0030] Based on the above principles, it can be seen that the formaldehyde adsorption particles are applied in stages. This structural method is not only easy to install and use for treating formaldehyde gas in confined spaces, but also fully meets the requirements. The purification structure has a low purification cost. To provide the next level of formaldehyde adsorption particles to the purification tube 10, no manual labor is required, and there is no need to set up electrical components to drive the self-adjusting plate 4. The device has a low manufacturing cost.

[0031] In addition, when the self-adjusting plate 4 pushes the formaldehyde adsorption particles, it also pushes the toothed belt 12. The toothed belt 12 passes 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 degree of 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 the left and right sides to rotate. Some formaldehyde adsorption particles are attached 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 shaft 20, these formaldehyde adsorption particles change position, improving the loosening effect. This causes the formaldehyde adsorption particles that are being diluted and reduced in size to change position in advance, or pass through the self-adjusting gap 21 and fall into the release space 23. As the self-adjusting wheel 8 rotates, the self-adjusting shaft 20 delivers the larger formaldehyde adsorption particles to the suction holes 11 and mesh holes 18 of the purification tube 10 in advance, ensuring that the suction holes 11 and mesh holes 18 receive the dilution components of the formaldehyde adsorption particles first, making the purification structure more reasonable.

[0032] It should be further explained that the purification tube 10 is not limited to a round tube. The purification tube 10 can also be a flat tube. The suction holes 11 and mesh holes 18 are distributed along the width 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. This not only improves the utilization rate of the formaldehyde adsorption particles, but also improves the purification efficiency.
