Problems solved by technology

[0003] (1) The filter usually does not have the function of dust removal, and the filtered dust accumulates in the filter, which affects normal use
[0004] (2) The filter usually does not have the function of replacing the filter element. After the filter element has been used for a period of time, more particles have accumulated, which increases the resistance of the filter and reduces the air output.

Embodiment 1

[0042] Such as Figure 1-3 Shown, a kind of square filter, it comprises square housing 4, and described square housing 4 is positioned at the middle part of whole filter, and described square housing 4 is fixedly installed with air intake cover plate 15, and at its other end The air outlet diffuser 1 is fixedly installed; the inside of the square housing 4 is installed with a fan 11 on one side of the air inlet cover plate, and a cyclone dust collector 10 is installed at the center of the square housing 4, and the cyclone dust collector An electric dust discharge valve 24 is installed on the device 10, and the inside of the square housing 4 is located at the fine filter 6 at the end where the air diffuser 1 is located; on the side wall of the square housing 4, it is located at the position where the fine filter 6 is located A fine filter replacement cover plate 27 is installed. By adopting the square filter of the above-mentioned structure, it can be used for air filtration. ...

Embodiment 2

[0052] The filtering method of any one of the described dust-exhausting square filters, it may further comprise the steps:

[0053] Step 1: Connect the power supply cable to the fan socket 19 and the electric dust valve socket 20, and power on;

[0054] In the second step, press the electric dust discharge valve switch 22, and the electric dust discharge valve 24 is opened;

[0055] In the third step, press the fan switch 21, and the fan 11 is turned on;

[0056] In the fourth step, the fan sends the external airflow into the square housing 4, and the airflow passes through the circular tubular cyclone 10-2 at a certain speed, and under the action of the internal impeller of the cyclone 10-2, a rotating airflow at a certain speed is generated. Under the action of the airflow, the particles in the air flow deviate from the centerline of the circular tube and gather at the tube wall of the circular tube-shaped cyclone 10-2, so that the particle concentration near the tube wall ...

Embodiment 3

[0061] The filter element replacement method of the dust-exhausting square filter is characterized in that it comprises the following steps:

[0062] Step 1: judge the timing of replacing the filter element; when the filter is used for a period of time, the air output of the air diffuser 1 is greatly reduced, indicating that a large amount of dust has accumulated on the fine filter 6, and the fine filter 6 needs to be replaced at this time;

[0063] Step 2: Replace the filter element; unscrew the cross recessed pan head screw 25, open the fine filter replacement cover 27, take out the fine filter 6 to be replaced, install a new fine filter 6, cover the fine filter replacement cover 27, and tighten the cross Groove pan head screw 25, described filter just can continue to use.

[0064] Working principle of the present invention:

[0065] The airflow at the inner edge of the circular tubular cyclone 10-2 is a high-concentration particle airflow. This airflow collides with the pi...

Abstract

The invention discloses a square filter and a filtering method. The square filter includes a square shell, wherein the square shell is located at the middle part of the filter; one end of the square shell is connected with an air inlet cover plate, and the other end of the square shell is connected with an air outlet diffuser; a fan, a cyclone dust collector, an electric dust exhaust valve and a fine filter are installed inside the square shell; and a fine filter replacement cover is installed on the surface of the square shell. The square filter can perform dust and aerosol filtering, has thefunctions of filter element replacement and dust discharging, and is convenient to use and low in cost.

Description

technical field [0001] The invention relates to a square filter and a filtering method used in the technical field of collective protection. The purpose of the filter is to filter air containing particles / aerosols to obtain clean air and has a dust removal function. The square filter is widely used Application Dust and aerosol filtration in the field of collective protection. Background technique [0002] At present, the filters used for dust and aerosol filtration in the field of collective protection have the following disadvantages: [0003] (1) The filter usually does not have the function of dust removal, and the filtered dust accumulates in the filter, affecting normal use. [0004] (2) The filter usually does not have the function of replacing the filter element. After the filter element has been used for a period of time, more particles have accumulated, which increases the resistance of the filter and reduces the air output. Contents of the invention [0005] Th...
