Description

Technical Field

[0001] This utility model relates to the field of formaldehyde removal equipment, and in particular to a formaldehyde removal equipment that recycles activated carbon. Background Technology

[0002] Formaldehyde removal equipment is a device specifically designed to remove harmful substances such as formaldehyde from indoor air. It is widely used in homes, offices, and industrial environments. This equipment typically utilizes technologies such as activated carbon and photocatalysis to decompose or remove formaldehyde from the air through physical or chemical adsorption, thereby improving air quality and reducing potential harm to human health.

[0003] However, most traditional formaldehyde removal devices have a simple structure and require the activated carbon to be replaced during use, which makes them inconvenient to use and results in poor formaldehyde removal efficiency.

[0004] Therefore, those skilled in the art have provided a formaldehyde removal device that recycles activated carbon to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a formaldehyde removal device that recycles activated carbon. Compared to most traditional formaldehyde removal devices, this device features a recycling mechanism. Through the control of the processing module, an electric telescopic rod closes the insulation plate, isolating the activated carbon in the tank within a relatively sealed space. The control module then operates the heating element to raise the temperature of the space, heating the activated carbon to a certain temperature, causing formaldehyde to volatilize. After heating for a period of time, the exhaust fan is turned on, and the gas is discharged outdoors through a connecting pipe. Through the recycling mechanism, the activated carbon can restore its adsorption capacity, ensuring high removal efficiency throughout its use, effectively controlling formaldehyde concentration, extending the lifespan of the activated carbon, reducing the frequency of replacement, and significantly reducing the workload of equipment management and maintenance.

[0037] A formaldehyde removal device utilizing recycled activated carbon includes a ventilated housing 1. A mounting plate 5 is fixedly connected to the upper surface of the ventilated housing 1.

A protective mesh 3 is fixedly connected to the lower end of the inner wall of the ventilated housing 1, and an air quality sensor 4 is fixedly connected to the lower part of the rear inner wall of the ventilated housing 1. This allows the device to detect the presence of methanol in the air via the air quality sensor 4. A processing module 7 is fixedly connected to the upper part of the rear outer wall of the ventilation housing 1. An activated carbon mechanism 8 is provided on the front outer wall of the ventilation housing 1. The activated carbon mechanism 8 includes a fixing groove 801 and a limiting slide groove 802.

A stainless steel wire filter screen 807 is fixedly connected to the upper and lower ends of the inner wall of the placement groove 806. A baffle 808 is fixedly connected to the rear end of the inner wall of the placement groove 806.

[0038] The inner wall of the ventilation housing 1 is provided with a recycling mechanism 9. The recycling mechanism 9 includes an auxiliary fixing frame 901, a heating tube 902, a limiting groove 904, an electric telescopic rod 906, a rotating rod 907, and an exhaust fan 9010. A control module 903 is fixedly connected to the outer wall of the rear end of the heating tube 902. A rack 905 is slidably connected to the lower end of the inner wall of the limiting groove 904. A heat insulation plate 908 is fixedly connected to the middle of the outer wall of the rotating rod 907. A gear 909 is fixedly connected to the outer wall of the rear end of the rotating rod 907. A connecting pipe 9011 is fixedly connected to the output end of the exhaust fan 9010.

[0039] Compared to most traditional formaldehyde removal equipment, this formaldehyde removal equipment is equipped with a recycling mechanism 9. Controlled by the processing module 7, the electric telescopic rod 906 closes the heat insulation plate 908, isolating the activated carbon in the placement tank 806 within a relatively sealed space. This allows the control module 903 to operate the heating tube 902 to raise the temperature within the space, heating the activated carbon to a certain temperature, causing formaldehyde to volatilize. After heating for a period of time, the exhaust fan 9010 is turned on, and the gas is discharged outdoors through the connecting pipe 9011. Through the recycling mechanism 9, the activated carbon can restore its adsorption capacity, ensuring a high removal efficiency throughout its use, effectively controlling the formaldehyde concentration, thereby extending the lifespan of the activated carbon, reducing the frequency of replacement, and significantly reducing the workload of equipment management and maintenance.

[0040] A fixing groove 801 is formed in the middle of the front outer wall of the ventilation housing 1. Limiting grooves 802 are respectively formed at the upper and lower ends of the middle of the inner wall of the ventilation housing 1. A limiting slider 805 slides inside the limiting grooves 802, allowing users to easily disassemble and replace the fixing plate 803. An auxiliary fixing bracket 901 is fixedly connected to the front end of the middle of the inner wall of the ventilation housing 1. A heating tube 902 is fixedly connected to the middle of the rear inner wall of the ventilation housing 1, allowing the front end of the heating tube 902 to be supported and fixed by the auxiliary fixing bracket 901, thereby improving the stability of the heating tube 902. Limiting grooves 904 are respectively formed in the upper and lower parts of the inner rear of the ventilation housing 1. The telescopic rod 906 is fixedly connected to the upper and lower parts of the rear end of the outer wall of one side of the ventilation housing 1, so that the electric telescopic rod 906 can move the rack 905 in the limiting groove 904. The rotating rod 907 is rotatably connected to the upper and lower ends of the inner wall of the front end of the ventilation housing 1. The output end of the electric telescopic rod 906 is fixedly connected to the rack 905. The rack 905 meshes with the gear 909, so that the electric telescopic rod 906 can control the heat insulation plate 908 to open or close. The exhaust fan 9010 is fixedly connected to the middle part of the outer wall of one side of the ventilation housing 1, so that the exhaust fan 9010 can exhaust the gas in the middle layer inside the ventilation housing 1.

[0041] Working principle: First, the device is installed on the indoor ventilation duct via the first flange 2 and the second flange 10. Then, the connecting pipe 9011 is connected to the outdoor exhaust pipe, and the power is turned on. When the air quality sensor 4 detects methanol, the ventilation fan 6 will start, allowing the methanol gas to come into contact with the activated carbon placed in the placement tank 806. The filtered gas is then transported back into the room through the ventilation duct. After running for a preset period of time, the ventilation fan 6 is turned off, and the processing module 7 will control the electric telescopic rod 906 to operate. Under the action of the meshing of the rack 905 and the gear 909, the electric telescopic rod 906 closes. The heat insulation plate 908 is closed, thus isolating the activated carbon in the placement tank 806 in a relatively sealed space. This allows the control module 903 to control the heating tube 902 to raise the temperature in the space, heating the activated carbon to a certain temperature to cause formaldehyde to volatilize. After heating for a period of time, the exhaust fan 9010 is turned on and the heat insulation plate 908 is opened slightly to allow the gas to be discharged outdoors through the connecting pipe 9011. After discharging for a period of time, the exhaust fan 9010 is turned off, the heat insulation plate 908 is fully opened, and the ventilation fan 6 is started. The above operation is repeated to filter and purify the methanol gas in the room.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
