Problems solved by technology

In this patent, when there is leakage in the entire scan of the high-efficiency filter (including the installation frame), since the sampling port covers the filter frame and the filter body at the same time, it is impossible to distinguish the filter frame or the filter body At the same time, since the patent scans the surface of the entire filter, there is no way to detect the leakage of the vertical gap outside the filter frame
[0004] At the same time, the existing products or technical patents do not consider that external interference particles will have a great impact on the test results when scanning the border. Use high-power ventilation and purification equipment, resulting in waste of energy, and the accuracy cannot be guaranteed

Embodiment 1

[0044] as attached figure 1 To attach Figure 5 As shown, the present invention is a detection device for scanning the frame of a high-efficiency filter scanning table, including a frame 1, a filter test fixture 18, a sampling head, a displacement drive mechanism, a controller, and an airflow anti-interference device.

[0045] In this embodiment, the filter test jig 18 is installed on the frame 1 to fix the filter 15 to be tested. Filters of different sizes match different sizes of jigs, and the frame 1 provides structural support.

[0046] In this embodiment, in order to ensure that the sampling head can take particles on the frame, the sampling head is a rotatable sampling head 14, including a sampling head body and a rotary cylinder 22 that drives its rotation, for the frame and body of the filter 15 to be tested. For scanning, the particle concentration at the designated position of the frame is taken. In order to improve the scanning efficiency and increase the accuracy ...

Embodiment 2

[0056] as attached Image 6 To attach Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the distance between the isolation baffle and the frame is 10 mm, that is, the distance between the isolation baffle and the frame is equal to the width of the sampling head, and the rest of the structure is the same as that of Embodiment 1.

[0057] This embodiment is set up like this. When scanning the frame, the projected area of ​​the sampling head can completely fall between the isolation baffle and the outer edge of the frame. If there is leakage at this time, it can be determined that it is an attached Figure 5 The frame vertical gap 20b of the frame of the filter to be tested leaks, and when the sampling head completely covers the frame of the filter to be tested and there is leakage, it is determined that the attached Figure 5 The frame plane gap 20a of the filter frame to be tested leaks, further distinguishing the leakage of the plane gap and ...

Abstract

The invention relates to a detection device for effective filter scanning table frame scanning. The device comprises; a rack, a filter test clamp installed on the rack; a sampling head configured to scan the frame and the body of a filter to be tested and adopt the particle concentration of the filter to be tested at the assigned position; a displacement driving mechanism connected with the sampling head to control the movement of the sampling head; the controller configured to perform signal control of the displacement driving mechanism to control the movement of the displacement driving mechanism to control the position of the sampling head and perform record and analysis of the data collected by the sampling head; and an air flow anti-interference device configured to isolate from the outside air to supplement the clean air flow when the sampling is performed by employing the sampling head. Through adoption of the mechanical structure, the detection device for effective filter scanning table frame scanning can complete isolate from the outside air influencing the test, can avoid the interference of the outside air, can ensure the accuracy of the scanning result and can clearly and effectively distinguish the difference between the frame leakage and the leakage of the filter body.

Description

technical field [0001] The invention belongs to the technical field of filter detection equipment, and in particular relates to a detection device and method for scanning the frame of a high-efficiency filter scanning table. Background technique [0002] With the increase of requirements for clean environment in all walks of life, high-efficiency filters are used more and more frequently, and the requirements for filtration efficiency are also higher and higher. Therefore, new requirements are put forward for the detection of high efficiency filters. However, although there are some high-efficiency filter detection equipment in the domestic and foreign markets, the scanning of the high-efficiency filter frame cannot meet the requirements of frame scanning due to technical reasons. Moreover, according to the current production process of the filter, the leakage of the frame has always been a problem that is difficult to solve, so the detection of the frame is also the top pr...
