Description

Technical Field

[0001] This utility model relates to the field of formaldehyde removal technology for wood-based panels, and more specifically, it relates to an environmentally friendly formaldehyde removal and penetration device for wood-based panels. Background Technology

[0002] During the production and processing of some composite boards, adhesives and other materials are used. When these adhesives cure, unreacted formaldehyde will be gradually released. The formaldehyde in the boards will gradually be released into the indoor air, affecting indoor air quality. Long-term exposure to formaldehyde may affect the nervous system, causing symptoms such as headaches, dizziness, and memory loss. Formaldehyde is classified as a Group 1 carcinogen by the International Agency for Research on Cancer (IARC). Long-term exposure to high concentrations of formaldehyde will increase the risk of cancers such as nasopharyngeal carcinoma and leukemia.

[0003] As people's living standards gradually improve, they also pay more attention to health, and environmentally friendly building materials are becoming increasingly popular.

[0004] Chinese patent document with publication number CN209774956U discloses a formaldehyde removal and penetration device for bare-packaged boards, which removes formaldehyde by placing the board on a roller and spraying it. However, with the above placement, the formaldehyde is mainly removed from one side of the board, resulting in poor formaldehyde removal effect.

[0005] Furthermore, the above solution uses warm air to heat the boards inside the box to promote the volatilization of formaldehyde. However, the box is a sealed structure, and continuously blowing hot air will cause excessive air pressure inside the box, creating a safety hazard.

[0006] Furthermore, a Chinese patent document with publication number CN221937042U discloses an environmentally friendly formaldehyde removal and penetration device for boards. It uses a structure such as a shelf and a trough for placing boards during formaldehyde removal. However, the edges of the boards suffer significant friction damage during placement and unloading, resulting in poor ease of use. Moreover, the above-mentioned solution has a simple structure, with spray nozzles for spraying formaldehyde-removing liquid only installed on the top and side panels inside the box. This means that formaldehyde removal can only be performed on one board at a time, resulting in poor formaldehyde removal effect and efficiency. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] In view of the problems existing in the prior art, this utility model provides an environmentally friendly formaldehyde removal and penetration device for building materials, so as to solve the technical problems of formaldehyde removal effect and efficiency of environmentally friendly building materials mentioned in the background art.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] An environmentally friendly formaldehyde removal and penetration device for wood-based panels includes a housing. A support frame is located at the bottom of the housing, and a limiting frame is located at the top. Multiple sets of placement rollers are fitted onto the limiting frame and support frame. A wood-based panel is positioned between two sets of placement rollers. Spray pipes are located on both sides of the top of each set of placement rollers, and atomizing nozzles are mounted on each spray pipe facing the wood-based panel. A liquid supply assembly is connected to each spray pipe. A heating air structure is connected to the bottom of the side wall of the housing. An air outlet pipe is located at the top of the housing, and a reaction chamber is connected to the end of the air outlet pipe. The reaction chamber is filled with a reaction liquid, and the end of the air outlet pipe extends into the reaction liquid. An exhaust pipe is located at the top of the reaction chamber.

[0012] The present invention is further configured such that the placement roller group includes a mounting frame, the mounting frame is symmetrically arranged on the support frame and the limiting frame, and multiple sets of limiting rollers are inclined and rotatably arranged on the mounting frame through bearings. The mounting frame realizes the stable installation of the limiting rollers on the support frame and the limiting frame, and the limiting rollers realize the stable method of the plate body in the box, as well as convenient loading and unloading.

[0013] The present invention is further configured such that an electric push rod is provided on the top of the box body, the limiting frame is provided at the bottom end of the electric push rod, and the spray pipe is installed at the bottom end of the limiting frame, which can move up and down synchronously with the limiting frame. Activating the electric push rod controls the raising and lowering of the limiting frame, which in turn controls the raising and lowering of the mounting bracket located on the limiting frame, which in turn controls the raising and lowering of the corresponding limiting roller. Thus, the installation position of the upper limiting roller on the limiting frame can be flexibly adjusted according to the different heights of the plate material.

[0014] The present invention is further configured such that a plurality of jet pipes are evenly arranged at the tail end of the gas outlet pipe, and a plurality of jet heads are evenly arranged on the jet pipes. The airflow delivered to the reaction chamber through the gas outlet pipes can be evenly sprayed out through the jet heads on the jet pipes, thereby improving the sufficiency and uniformity of contact between the formaldehyde component in the airflow and the reaction liquid, and improving the formaldehyde purification effect of the discharged gas.

[0015] The present invention is further configured such that the heating air structure includes a heater, the output end of the heater is provided with an air duct, and the tail end of the air duct extends into the interior of the box. Through the cooperation of the heater and the air duct, hot air can be transported into the interior of the box, thereby increasing the temperature inside the box and improving the volatilization efficiency of formaldehyde inside the board body.

[0016] The present invention is further configured such that the liquid supply component includes a liquid storage tank, a water pump is connected to the liquid storage tank, the output end of the water pump extends into the tank body, and a liquid supply hose is provided between the water pump and the spray pipe. When the water pump is started, the formaldehyde removal agent in the liquid storage tank can be extracted and delivered to the spray pipe through the liquid supply hose, and then sprayed towards the board body through the atomizing nozzle on the spray pipe, thereby contacting and reacting with the formaldehyde in the board body to remove the formaldehyde. In addition, the atomized formaldehyde removal agent can contact the formaldehyde in the dispersed airflow inside the tank to remove it. In this way, the formaldehyde removal effect can be effectively improved. Here, the liquid supply hose is used so that when the limiting frame moves the spray pipe, the liquid supply hose can move with it, so that the length of the liquid supply hose is sufficient to ensure the smooth movement of the spray pipe.

[0017] The present invention is further provided that a drain pipe is provided at the bottom of the box body, and a drain valve is provided on the drain pipe. The drain pipe is used to discharge the liquid accumulated at the bottom of the box body, and the drain valve is used to control the opening and closing of the drain pipe.

[0018] The present invention is further provided that the front of the box body is provided with a sealed box door, and a protective lock is provided between the sealed box door and the box body. The sealed box door is used to control the opening and sealing of the front of the box body, and the protective lock is used to lock the sealed box door. This is the prior art, and the present invention will not elaborate on it.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, this utility model provides an environmentally friendly formaldehyde removal and penetration device for wood-based panels, which has the following beneficial effects:

[0021] 1. This utility model features a support frame and a limiting frame inside the box, with placement rollers on the support frame and limiting frame for placing the board body. In use, the board body is placed in the two sets of limiting rollers on the placement rollers, supported by the limiting rollers on the support frame and limited by the limiting rollers on the limiting frame, thus allowing the board body to be stably placed longitudinally inside the box. The rotating roller structure allows for quick and easy installation and removal of the board body from the box.

[0022] 2. This utility model, by setting up a heating air structure, allows for the activation of a heater during the formaldehyde removal process of the board material itself. The heater delivers hot air through a gas pipe to the interior of the chamber, heating the interior and promoting the volatilization of formaldehyde within the board material, thus improving the formaldehyde removal effect. Excess airflow is then delivered through an exhaust pipe to the reaction chamber, where it reacts with the reaction liquid, allowing the formaldehyde in the airflow to be removed. After the reaction is complete, clean airflow is discharged through an exhaust pipe. If necessary, the airflow discharged through the exhaust pipe can be further purified using existing technologies such as activated carbon purification. This utility model will not elaborate on this aspect, focusing only on the formaldehyde removal process.

[0023] 3. In this invention, spray pipes are installed on both sides of the board body. While hot air is circulated to promote the volatilization of formaldehyde within the board body, a water pump can be activated. Under the action of the water pump, the formaldehyde removal agent in the storage tank can be extracted and delivered to the spray pipes through the liquid supply hose. The agent is then sprayed towards the board body through the atomizing nozzles on the spray pipes, thus contacting and reacting with the formaldehyde in the board body to remove it. This invention sprays from both sides of the board body, which can improve the formaldehyde removal effect. Furthermore, the atomized formaldehyde removal agent can contact the formaldehyde in the dispersed airflow inside the chamber to remove it. This effectively improves the formaldehyde removal effect. During this process, excess liquid will fall to the bottom of the chamber and can be discharged through the drain pipe. Attached Figure Description
