Description

Technical Field

[0001] This utility model relates to the field of paint treatment technology, and in particular to a honeycomb paperboard for paint filtration. Background Technology

[0002] Paint is a chemical mixture coating that can firmly cover the surface of an object, serving functions such as protection, decoration, marking, and other special purposes. Paint is mainly composed of film-forming substances, fillers, solvents, and additives. Paint spraying sites need to be equipped with paint mist purification and treatment equipment to filter and treat the discharged paint-containing waste gas.

[0003] Existing paint mist purification equipment has the following drawbacks in its internal filtration components: Common paint mist purification systems in spray booths generally use water curtain systems. During spraying operations, the blower blows the organic waste gas generated indoors onto the water curtain, which is then filtered using a circulating water curtain. Alternatively, filtration can be done using absorbent felt or other methods. Water curtain methods generate a large amount of waste gas, wastewater, and waste liquid, resulting in high costs. Absorbent felt methods tend to become clogged after a period of use and require frequent replacement. Therefore, we propose a honeycomb paperboard for paint filtration. Utility Model Content

[0004] The main objective of this invention is to provide a honeycomb paperboard for paint filtration. By using a filter assembly made of high-strength paperboard, it can effectively filter and treat paint-containing exhaust gas, thus effectively solving the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A honeycomb paperboard for paint filtration includes an inner paperboard sleeve and an outer sheath. The inner paperboard sleeve has an installation cavity inside and is filled with a honeycomb perforated plate. The inner paperboard sleeve is inserted into the outer sheath. The outer sheath has a side plate at one end away from the inner paperboard sleeve. Both ends of the side plate are integrally formed with end plates, and the side plate has a diamond-shaped hole at the position between the end plates.

[0007] Furthermore, slots are provided on both sides of the inner wall of the outer sheath. A limiting plate is bonded inside the slot, and the end of the inner cardboard sleeve is attached to the surface of the limiting plate. An absorbent felt is bonded between the limiting plates. Slots are provided on both sides inside the outer sheath. The limiting plate can be inserted into and bonded to the slot. When the inner cardboard sleeve is inserted into the outer sheath, its end abuts against the surface of the limiting plate. The limiting plate provides limiting support for the inner cardboard sleeve. At the same time, an adhesive groove is provided inside the limiting plate. When needed, an absorbent felt can be bonded between the adhesive grooves. The absorbent felt can then be used to re-adsorb the waste gas filtered by the honeycomb perforated plate, thereby improving the treatment quality.

[0008] Furthermore, the outer wall of the honeycomb perforated plate is attached to the inner wall of the mounting cavity, and the outer wall of the inner cardboard sleeve is attached to the inner wall of the outer sheath; the connections between the various components are tightly fitted to ensure the sealing of the connections.

[0009] Furthermore, the inner cardboard sleeve is made of D-1.5 material, 700g / m². 3 Corrugated cardboard, AB flute type; using AB flute type, strength D-1.5, 700g / m². 3 The corrugated cardboard is used as the inner cardboard sleeve, giving it high strength.

[0010] Furthermore, adhesive grooves are provided on opposite sides inside the limiting plate, and the side of the absorbent felt is bonded to the inside of the adhesive grooves; the adhesive grooves facilitate the bonding of the end position of the absorbent felt, so that its end position is retracted inside the limiting plate.

[0011] Compared with the prior art, this utility model has the following beneficial effects: The main body of the filter device is composed of an outer sheath and an inner cardboard sleeve. The inner cardboard sleeve is inserted into one end of the outer sheath. An installation cavity is provided inside the inner cardboard sleeve and filled with a honeycomb perforated plate. During installation, the end of the inner cardboard sleeve is aligned with the exhaust end. The waste gas to be treated is initially treated and then discharged into the honeycomb perforated plate. The honeycomb perforated structure inside the plate adsorbs the paint in the waste gas, purifying it. The waste gas treated by the honeycomb perforated plate is then discharged after secondary adsorption through the diamond-shaped holes inside the side plate, improving the quality of waste gas treatment. High-strength corrugated board is used. Using cardboard as the base material ensures the overall structural strength of the filter device while maintaining low cost. It effectively filters exhaust gas, is easy to replace, and reduces treatment costs. The outer sheath has slots on both sides inside, into which a limiting plate can be inserted and glued. When the inner cardboard sleeve is inserted into the outer sheath, its end abuts against the surface of the limiting plate, which provides support and restraint. The limiting plate also has adhesive grooves inside, allowing for the bonding of adsorption felt between the grooves when needed. This adsorption felt then re-adsorbs the exhaust gas filtered by the honeycomb perforated plate, improving treatment quality. Attached Figure Description
