Description

Technical Field

[0001] This utility model relates to the field of formaldehyde adsorption technology, and more specifically, to a formaldehyde adsorption board. Background Technology

[0002] Formaldehyde adsorption boards are functional boards designed to reduce indoor formaldehyde pollution. They primarily reduce the concentration of formaldehyde in the air through physical adsorption or chemical decomposition.

[0003] Few paper-faced gypsum boards currently on the market have the function of absorbing formaldehyde. The few paper-faced gypsum boards that do have the function of absorbing formaldehyde often simply add an activated carbon adsorption layer to the traditional gypsum board to absorb formaldehyde in the air. The adsorption effect is limited and cannot play a good role in absorbing and purifying formaldehyde.

[0004] A search revealed that Chinese patent CN212358837U discloses a paper-faced gypsum board that adsorbs formaldehyde. The board uses a formaldehyde cleaning layer to adsorb and decompose formaldehyde in the air, and a thermal expansion layer that contracts and resets to adhere to the upper surface of the gypsum substrate, thereby pushing out purified air to achieve the cyclic adsorption and purification of formaldehyde in the air.

[0005] In actual use, the aforementioned formaldehyde-absorbing gypsum board requires multiple bolts for installation, making the process cumbersome. Furthermore, if the two formaldehyde-absorbing boards are not level, deviations may occur during installation, causing them to loosen and resulting in an unstable connection. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a formaldehyde adsorption board to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A formaldehyde adsorption board includes two connecting frames, each connecting frame having an adsorption board on its inner side, an adsorption board having a support layer inside, an adsorption layer on both sides of the support layer, an air-permeable layer on one side of the adsorption layer, and a connecting component and a positioning mechanism on the outer side of the connecting frames, with the connecting component positioned on one side of the positioning mechanism.

[0009] The connecting assembly includes a connecting rod mounted on one side of the connecting frame. Two first insertion holes and two second insertion holes are formed on the inner side of the connecting rod. The two first insertion holes are positioned between the two second insertion holes. A threaded rod is rotatably connected to the inner side of each first insertion hole. Two insertion plates are fixedly connected to one side of the connecting frame, and these plates are inserted into the inner sides of the first insertion holes. Two first toothed plates are fixedly connected to one side of the connecting frame. Two second toothed plates are fixedly connected to the other side of the connecting frame, with one side of each second toothed plate meshing with one side of each first toothed plate. Two insertion rods are fixedly connected to the other side of the connecting frame, and these rods engage with the inner sides of the insertion plates. Both the inner sides of the insertion plates and the inner sides of the insertion rods are threadedly connected to the threaded rods. The support layer is made of a honeycomb substrate, the adsorption layer is made of activated alumina, and the breathable layer is made of porous fiber material.

[0010] By adopting the above technical solution, the splicing process between connecting frames becomes simple and quick, improving work efficiency.

[0011] As a further description of the above technical solution: the positioning mechanism includes two limiting blocks, which are fixedly connected to both ends of the adsorption plate. A positioning groove is provided on the front side of the connecting frame, and the limiting blocks are slidably connected to the inner side of the positioning groove. Two bolts are installed on one side of the connecting frame, and the adsorption plate and the connecting frame are detachably connected by the bolts. Multiple grooves are provided inside the connecting frame, and a telescopic spring is fixedly connected inside the groove. A telescopic block is fixedly connected to one end of the telescopic spring, and the telescopic block is engaged with the inner side of the limiting block.

[0012] By adopting the above technical solution, the adsorption plates can be replaced regularly, reducing the decline in equipment performance caused by adsorption saturation.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting up connecting components, compared with the existing technology, the two connecting frames can be quickly connected and fixed by inserting two connecting frames into the connecting rod. This makes the splicing process between the two connecting frames simple and quick, and ensures that the spliced ​​connecting frame structure is stable, not easy to loosen or fall off, shortens the installation time, and improves work efficiency.

[0015] 2. By setting up a positioning mechanism, compared with the existing technology, the two limiting blocks inside the positioning groove can position the adsorption plate during installation, and the multiple grooves inserted into the telescopic block can be positioned during the installation process, so that the adsorption plate can be quickly aligned and fixed in position, and the adsorption plate can be replaced independently, reducing the performance degradation of the equipment due to adsorption saturation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The embodiments disclosed in this application are as follows: Figure 1-7 The formaldehyde adsorption board shown includes two connecting frames 1, an adsorption board 2 is provided on the inner side of each of the two connecting frames 1, a support layer 3 is provided inside the adsorption board 2, an adsorption layer 4 is provided on both sides of the support layer 3, a breathable layer 5 is provided on one side of the adsorption layer 4, and a connecting component and a positioning mechanism are provided on the outer side of the connecting frame 1, with the connecting component located on one side of the positioning mechanism.

[0026] The connecting assembly includes a connecting rod 6, which is mounted on one side of the connecting frame 1. Two first insertion holes 7 and two second insertion holes 8 are formed on the inner side of the connecting rod 6, with the two first insertion holes 7 positioned between the two second insertion holes 8. A threaded rod 9 is rotatably connected to the inner side of each first insertion hole 7. Two insert plates 10 are fixedly connected to one side of the connecting frame 1, and the insert plates 10 are inserted into the inner side of the first insertion holes 7. Two first toothed plates 11 are fixedly connected to one side of the connecting frame 1, and two second toothed plates 12 are fixedly connected to the other side of the connecting frame 1. One side of each second toothed plate 12 engages with one side of each first toothed plate 11. Two insert rods 13 are fixedly connected to the other side of the connecting frame 1, and the insert rods 13 engage with the inner side of each insert plate 10. The inner sides of the insert plate 10 and the insert rod 13 are both threadedly connected to the threaded rod 9. The support layer 3 is made of honeycomb substrate, the adsorption layer 4 is made of activated alumina, and the breathable layer 5 is made of porous fiber material. The two connecting frames 1 can be tightly connected by the engagement of the protruding teeth on one side of the second toothed plate 12 and the protruding teeth on one side of the first toothed plate 11. The insert rod 13 is used to lock the inner side of the insert plate 10, and the insert rod 13 and the insert plate 10 can be connected together by the threaded rod 9 and fixed with the connecting rod 6. This can stably connect the two connecting frames 1 together, making it less likely to loosen or fall off. The splicing process between the two connecting frames 1 is simple and quick, shortening the installation time.

[0027] Reference Figure 3 and 5 As shown, the positioning mechanism includes two limiting blocks 14, which are fixedly connected to both ends of the adsorption plate 2. A positioning groove 15 is provided on the front side of the connecting frame 1, and the limiting blocks 14 are slidably connected to the inner side of the positioning groove 15. Two bolts 19 are installed on one side of the connecting frame 1, and the adsorption plate 2 and the connecting frame 1 can be detachably connected by the bolts 19. Multiple grooves 16 are provided inside the connecting frame 1, and a telescopic spring 17 is fixedly connected inside the groove 16. A telescopic block 18 is fixedly connected to one end of the telescopic spring 17, and the telescopic block 18 is engaged with the inner side of the limiting block 14. The wavy surface on the outer side of the adsorption plate 2 can increase the air contact area, allowing formaldehyde molecules to come into full contact with the breathable layer 5. The two positioning grooves 15 can provide positioning for the adsorption plate 2 during installation. The telescopic action of the multiple grooves 16 allows the multiple telescopic blocks 18 to be inserted into the limiting block 14 for positioning when the limiting block 14 is in contact with the inner side of the positioning groove 15, so that the adsorption plate 2 can be quickly aligned and fixed in position.

[0028] Working principle of this utility model: This utility model designs a formaldehyde adsorption board, the specific structure of which is shown in the attached instruction manual. Figure 1-7As shown, in this technical solution, through the cooperation between various structures, when the adsorption plate 2 needs to be installed, firstly, two limiting blocks 14 are inserted into the positioning grooves 15. The two positioning grooves 15 can provide positioning conditions for the installation of the adsorption plate 2. When the limiting blocks 14 move inside the positioning grooves 15, they can squeeze the cut surface of one side of the telescopic block 18. The telescopic effect of the telescopic spring 17 allows the telescopic block 18 to move inside the groove 16. And the reset elastic force of the groove 16 makes the limiting block 14 fit with the inside of the positioning groove 15. The groove 16 can push the telescopic block 18 to engage with the limiting block 14. Then, the adsorption plate 2 can be fixed to the connecting frame 1 by two bolts 19. When the adsorption plate 2 needs to be replaced, the two bolts 19 are removed, and then the adsorption plate 2 can be quickly removed by pulling it.

[0029] When assembling two connecting frames 1, firstly, insert the two first toothed plates 11 and the insert plate 10 on one side of one connecting frame 1 into the second insertion hole 8 and the first insertion hole 7 respectively. Then, insert the second toothed plate 12 on one side of the other connecting frame 1 into the first insertion hole 7. The second toothed plate 12 is inserted into the inner side of the first insertion hole 7, and the other connecting frame 1 is pressed down so that the insert rod 13 can slide inside the first insertion hole 7, so that the insert rod 13 can move to the inner side of the insert plate 10, while the second toothed plate 11... One side of the protruding tooth can mesh with the protruding tooth on one side of the first toothed plate 11, and rotate the threaded rod 9. The threaded rod 9 is threadedly connected to the insert plate 10 and the insert rod 13, so that the threaded rod 9 can connect the insert plate 10 and the insert rod 13, so as to quickly splice the two connecting frames 1 and the connecting rod 6. The wavy surface on both sides of the adsorption plate 2 can increase the air contact area, so that formaldehyde molecules can come into full contact with the breathable layer 5. The adsorption layer 4 can adsorb formaldehyde molecules, and the support layer 3 can provide structural support inside the adsorption plate 2.
