Embodiment 1

[0031] Such as figure 1 As shown, a device for measuring the filtration efficiency of a filter element includes a base 1, a detection mechanism 11 and a sealing box 10 arranged on the top surface of the base 1, and a power supply for the whole device.

[0032] The detection mechanism 11 and the sealing box 10 are communicated through the intake pipe 13; the special-shaped filter element 7 is arranged on the top of the sealing box 10, the compression cylinder 4 is arranged above the special-shaped filter element 7 through the support mechanism, and the compression cylinder 4 and the special-shaped filter element 7 are coaxially arranged .

[0033] The free end of the cylinder rod of the compression cylinder 4 is provided with a positioning pressing member 6 .

[0034] At least one ventilation hole is arranged on the top of the sealed box 10 .

[0035] The flange at the bottom end of the special-shaped filter element 7 is fixedly connected with the top of the sealing box 10 th...

Embodiment 2

[0044] Based on Embodiment 1, in order to further facilitate the control of the detection mechanism and the corresponding feedback display of the detection results, the device for measuring the filtration efficiency of the filter element further includes a controller 12 electrically connected to the detection mechanism 11 . The controller 12 is any one or a combination of control buttons or display screen controllers.

[0045] The usage method of the present invention:

[0046] The filter element to be inspected and the sealing box are fixedly connected by nuts and locking washers to form a closed body, which ensures complete compression, compactness, and airtightness before the inspection begins. Start the detection mechanism, the detection mechanism has a built-in air extraction device to pump air, and the air enters the detection mechanism after being filtered by the filter element. The detection mechanism can detect the current air quality of the gas in the sealed box, and...

Abstract

The invention discloses a device for measuring the filtering efficiency of a filter element, which comprises a base, and a detection mechanism and a sealing box which are arranged on the top surface of the base and are communicated with each other through an air inlet pipe. A special-shaped filter element is arranged at the top of the sealing box, a pressing air cylinder is arranged above the special-shaped filter element through a supporting mechanism, and a positioning pressing piece is arranged at the free end of an air cylinder rod. According to the invention, the purpose of detecting thefiltering efficiency of the filter element is achieved by detecting the quality index of air filtered by the filter element. Compared with a filter detection device in the prior art, the device is compact in structure and suitable for daily detection of a special-shaped filter element. The device is compact in structure, high in specialty, reliable in detection result, practical in function, low in manufacturing cost and high in use and popularization value.

Description

technical field [0001] The invention belongs to the field of detection and measurement of purification devices, and in particular relates to a device for measuring the filtration efficiency of a filter core. Background technique [0002] In recent years, the problem of air pollution in our country has become increasingly serious. For the purpose of protecting health and preventing respiratory diseases, a special-shaped filter element is used as an unconventional filter element and is used in the aviation field. Under the current circumstances, there is no low-cost and convenient way for users to detect the filtration effect and filtration efficiency of the heterosexual filter element except for purchasing professional testing equipment or testing in a special testing laboratory. [0003] To sum up, how to design a filter detection device that can quickly test the filtration effect and filtration efficiency of a special-shaped filter element, so as to effectively ensure the p...
