Description

Technical Field

[0001] The utility model belongs to the technical field of formaldehyde removal equipment, and specifically relates to a formaldehyde removal device for producing formaldehyde-free glue. Background Art

[0002] Formaldehyde-free glue refers to adhesives that do not contain formaldehyde. It is mainly used in the artificial board and building materials industries and is an environmentally friendly glue. Formaldehyde-free glue contains formaldehyde during production, but it will be removed after production.

[0003] In the prior art, formaldehyde removal is usually carried out using a formaldehyde removal device. For example, the utility model with patent announcement number CN216170565U discloses a formaldehyde removal device for producing environmentally friendly glue. The device includes an environmentally friendly glue formaldehyde removal device body, an electric heater, a first drive motor and a second drive motor. A support base is fixedly installed at the bottom end of the environmentally friendly glue formaldehyde removal device body, a glue adding port is fixedly installed on the side of the environmentally friendly glue formaldehyde removal device body, and a formaldehyde removal cabin is installed inside the environmentally friendly glue formaldehyde removal device body; an electric heater is fixedly installed on the side of the formaldehyde removal cabin, and a filter is installed at the bottom end of the formaldehyde removal cabin. By placing a chlorobenzene particle adsorption layer inside the formaldehyde removal cabin, the glue can fully contact the chlorobenzene particle adsorption layer when flowing into the formaldehyde removal cabin, and the formaldehyde in the glue can be adsorbed by the chlorobenzene particle adsorption layer.

[0004] The aldehyde removal device sets a chlorobenzene particle adsorption layer inside the aldehyde removal chamber, and removes the aldehyde from the glue through the chlorobenzene particle adsorption layer. However, the contact area between the glue and the chlorobenzene particle adsorption layer is limited, and the glue flows downward due to gravity, so only part of the glue is in contact with the chlorobenzene particle adsorption layer, and part of the glue cannot be in contact with the chlorobenzene particle adsorption layer. Although a stirring rod is provided for stirring, some of the glue in the aldehyde removal chamber cannot move to the chlorobenzene particle adsorption layer, so that some of the glue cannot be de-aldehydeated, and the aldehyde removal effect is insufficient.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0026] Embodiment 1:

[0027] like Figures 1 to 4As shown, a formaldehyde-free glue production device comprises a formaldehyde-free box 1 and a formaldehyde-free part 2; the formaldehyde-free box 1 comprises a box body 11, a feed port 12 and a discharge port 13; a feed port 12 is provided on the top of the box body 11, and a discharge port 13 is provided on the bottom thereof; the feed port 12 and the discharge port 13 are both communicated with the inside of the box body 11, and the glue enters from the feed port 12 and is discharged from the discharge port 13; the formaldehyde-free part 2 comprises a first plate body 21, a second plate body 22 and a chlorobenzene particle adsorption layer 23; the first plate body 21 and the second plate body 22 are arranged inside the box body 11 at intervals along the height direction of the box body 11; The first plate 21 and the second plate 22 are inclined in opposite directions; the first plate 21 and the second plate 22 are arranged alternately to form a curved channel 14, which is connected with the feed port 12 and the discharge port 13. The glue enters from the feed port 12, then passes through the channel 14, and is finally discharged from the discharge port 1; a chlorobenzene particle adsorption layer 23 is provided on the surface of the first plate 12 and the second plate 22; a gap 24 is left between the lower ends of the first plate 21 and the second plate 22 and the inner wall of the box body 11; the feed port 12 is located directly above the high end of the first plate 21 at the top of the box body 11.

[0028] Working method:

[0029] When removing formaldehyde, glue is injected into the box body 11 through the feed port 12. The glue enters the box body 11 and falls onto the highest first plate body 21 in the box body 11, and contacts the chlorobenzene particle adsorption layer 23 on the first plate body 21. The chlorobenzene particle adsorption layer 23 contacts the glue and adsorbs formaldehyde. Then the glue slides down along the inclined direction of the first plate body 21. In the process of moving toward the bottom end of the first plate body 21, the glue expands the contact area with the chlorobenzene adsorption layer 23. Because the glue contacts the chlorobenzene particle adsorption layer 23, the glue and the chlorobenzene particle adsorption layer 23 are in contact with each other. The flow velocity of the contacting portion is lower than the flow velocity of the portion not in contact with the chlorobenzene particle adsorption layer 23, so that the glue that has not contacted with the chlorobenzene adsorption layer 23 after entering the housing 11 contacts with the chlorobenzene adsorption layer 23 during the movement, and the glue enters the notch 24 and falls from the notch 24 onto the second plate body 22. The chlorobenzene particle adsorption layer 23 on the second plate body 22 contacts with the glue and adsorbs the formaldehyde thereon, and this process is repeated. By extending the channel 14, the contact area between the chlorobenzene adsorption layer 23 and the glue is expanded.

[0030] like Figure 5 As shown, preferably, a chlorobenzene particle adsorption layer 23 is provided on the inner wall of the box body 11. After the glue enters the box body 11, it also contacts the inner wall of the box body 11. A chlorobenzene particle adsorption layer 23 is provided on the inner wall of the box body 11 to expand the contact area between the glue and the chlorobenzene particle adsorption layer 23, ensure that the glue is in full contact with the chlorobenzene particle adsorption layer 23, and improve the formaldehyde removal effect.

[0031] like Figure 2 and Figure 4As shown, preferably, the formaldehyde removal box 1 also includes a support leg 15; the support leg 15 is arranged on the bottom surface of the box body 11; the discharge port 13 is located at the bottom surface of the box body 11, and the support leg 15 raises the height of the bottom surface of the box body 11, and a collection container is arranged directly below the discharge port 13 to facilitate the discharge of glue from the discharge port 13.

[0032] Embodiment 2:

[0033] like Figure 4 and Figure 5 As shown, compared with the first embodiment, the difference is that the formaldehyde removal part 2 also includes a diverter plate 25; the diverter plate 25 is arranged at the notch 24 to cover the notch 24, so that the glue falls evenly after passing through the diverter plate 25; the diverter plate 25 is arranged horizontally; a plurality of through holes are opened on the diverter plate 25; the through holes are distributed in a rectangular array.

[0034] like Figure 4 and Figure 5 As shown, preferably, the formaldehyde removal part 2 also includes a third plate 26; the third plate 26 is obliquely arranged between the first plate 21 and the second plate 22; a group of third plates 26 is arranged between the first plate 21 and the second plate 22; the number of a group of third plates 26 is at least two, and the plurality of third plates 26 are evenly spaced and distributed along the height direction of the box 11; one end of the third plate 26 is connected to the plate surface of the diverter plate 25, and the other end thereof is spaced from the inner wall of the box 11; when the glue flows onto the diverter plate 25, the diverter plate 25 diverts the glue so that the glue flows into the third plate 26 and the first plate 21 or the second plate 22 accordingly; the plate surface of the third plate 26 is inclined downward After the glue enters the third plate body 26, it moves along the inclined direction of the third plate body 26 and moves toward the notch 24, just like the first plate body 21 and the second plate body 22; the end of the third plate body 26 connected to the diverter plate 25 is higher than the end of the third plate body 26 and the box body 11 with a gap; a chlorobenzene particle adsorption layer 23 is provided on the plate surface of the third plate body 26, and the chlorobenzene particle adsorption layer 23 on the third plate body 26 absorbs formaldehyde on the glue. By providing the third plate body 26, the area of ​​the chlorobenzene particle adsorption layer 23 is increased, and the contact area between the glue and the chlorobenzene particle adsorption layer 23 is expanded, ensuring that the glue is in full contact with the chlorobenzene particle adsorption layer 23, and the glue is fully de-aldehydeated.
