Embodiment 1

[0125] Such as Figure 1 to Figure 5 Shown, the structure of a kind of no-cleaning air filtering device 6 is:

[0126] It includes a box body 1 and a filter screen 2. The box body 1 is in the shape of a cuboid as a whole. The filter screen 2 is an activated carbon fiber cloth filter screen. 7 used together;

[0127] It is an air treatment device for a full-heat fresh air ventilator, the model of the activated carbon fiber cloth is KJC10-1100; it also includes a rotating shaft 3, a motor 4 and a tray 5;

[0128] The box body 1 includes a lower front and rear baffle plate 101, a middle front air outlet 102, a middle rear air outlet 103, an upper front and rear groove plate 104, and a side plate 105; The motor 4 is arranged outside the side plate 105 on one side, and the motor 4 is fixedly connected to the left end of the rotating shaft 3; the tray 5 is arranged in the lower part of the front and rear groove plates 104;

[0129] The filter screen 2 comprises an upper filter sc...

Embodiment 2

[0144] Such as Figure 1 to Figure 5 As shown, the main structure of a no-cleaning air filter device 6 is the same as that of Embodiment 1, and is used in conjunction with a photoelectric control instrument (not shown in the figure) that is arranged on the no-cleaning full-heat fresh air ventilator 7, and it includes a transmitter and a The receiving end is an active photoelectric detection system electronic switch using pulse modulation, which converts the change of light intensity between the transmitting end and the receiving end into a change in current to achieve the purpose of detection; the transmitting end and the receiving end The end is set at the front and rear of the working layer of the filter in the middle, and the limit stroke hole is made on the filter 2 first. When the filter 2 is polluted after a certain set time, the motor 4 is started. When the light passes through the first When the limit travel hole is punched, the photoelectric control instrument control...

Embodiment 3

[0147] Such as Figure 1 to Figure 5 As shown, the structure of a no-cleaning air filter device 6 is completely the same as that of Embodiment 1. The replacement operation method of new and old filter screen 2 is to replace new and old filter screen 2 with manually starting and shutting down the motor, and first manually starts motor 4 to make new filter screen 2 work from the upper filter screen stack 201 to the middle filter screen The layer 202 rotates, and the old filter screen 2 rotates from the middle filter screen working layer 202 to the bottom dirty screen reel 203 until the replacement of the new and old filter screen 2 is completed, and then the motor is turned off manually; the working environment is relatively bad, and the filter screen is often blocked When the time comes, you can use the above-mentioned manual operation method, so that the contaminated filter screen can be replaced at any time.

Abstract

The invention provides a no-clean air filtration device and a new and old filter screen replacement method thereof and belongs to the fresh air ventilation air handling technical field. The no-clean air filtration device comprises a box and a filter screen and also comprises a rotary shaft, a motor and a tray; the box comprises a lower portion front baffle, a lower portion rear baffle, the front air inlet, the rear air outlet, an upper front groove plate, an upper rear groove plate and side plates; two ends of the rotary shaft are arranged on the lower portions of the side plates in a rotating mode; the motor is arranged outside the side plate which is arranged on one side; the motor is fixedly connected with the left end of the rotary shaft; the tray is arranged at the lower position inside the upper front groove plate and the upper rear groove plate; the filter screen comprises a filter screen laminating layer, a filter screen working layer and a fouling screen winding drum; the filter screen laminating layer is arranged above the tray; the filter screen working layer is vertically arranged on one side of the front air inlet; the fouling screen winding drum is arranged on the rotary shaft in a sleeving mode. The total using time of the no-clean air filtration device is 2 to 20 years. According to the new and old filter screen replacement method, the replacement can be performed manually or the filter screen can be matched with an intelligent control module which is arranged on a no-clean total heat fresh air ventilator for use. According to the no-clean air filtration device and the new and old filter screen replacement method thereof, the manpower and material resources are saved and sales are expanded.

Description

technical field [0001] The invention relates to an air filter device, in particular to a no-cleaning air filter device and a method for replacing new and old filter nets, and belongs to the technical field of fresh air ventilation and air treatment. Background technique [0002] The severe pollution of the environment by building materials, the emission of automobiles and industrial waste gas, etc. have already caused great harm to the living environment. The requirement for a low-carbon and environmentally friendly environment has become the common voice of mankind. Especially in recent years, after the use of PM2.5 particle detectors nationwide to monitor air quality, it was found that the air quality of most cities in China did not meet the safety standards, which aroused the country's great attention. In order to improve the living environment, air conditioners have entered the stage of popularization all over the world, but the negative impact of the use of air conditio...
