Description

Technical Field

[0001] The utility model relates to the field of air filter leak detection, and specifically relates to an air filter scanning leak detection device. Background Technique

[0002] High-efficiency filter leak detection is used for the integrity test of high-efficiency filters (commonly known as high-efficiency filter leak detection). The purpose of leak detection is to timely detect possible defects in the high-efficiency filter itself and its installation by checking the sealing performance of the high-efficiency filter and the connection parts with the installation frame, etc., and take corresponding remedial measures to ensure the cleanliness of the area.

[0003] After retrieval, CN 220583787 U, an air filter scanning leak detection device. After the device finishes scanning and detecting leaks, the air filter after scanning and detecting leaks is transferred to the unloading mechanism. The U-shaped block pulls the pull plate to move outwards, so that the air filter loses the extrusion pressure. Affected by gravity, the air filter falls onto the lifting plate. Then, the lifting plate drives the air filter to intermittently descend a certain distance, facilitating the next air filter to fall into the collection frame, realizing the function of automatic unloading, saving time and effort, reducing the labor intensity of workers, and improving work efficiency. Qualified air filters will fall into the front-side unloading mechanism, and unqualified air filters will fall into the right-side unloading mechanism, completing the classified unloading and placement of qualified and unqualified air filters, which is convenient for later processing.

[0004] However, there are still certain defects in the above application: the above application only performs leak prevention detection on one side of the filter, while in the prior art, during the airtightness test of the filter, it is usually necessary to perform airtightness tests on both sides of the filter. Double-sided detection can more comprehensively evaluate the sealing performance of the filter in different directions and ensure that there are no potential leakage points. Therefore, an air filter scanning leak detection device is provided here that can perform continuous double-sided detection on the filter. Content of the Utility Model

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] Example 1

[0023] See also Figure 1-5, an air filter scanning and leak detection device, comprising a base 1, a support base 2 is fixedly installed on the base 1, and a fence 3 is fixedly installed on the base 1 outside the support base 2, a rotating disk 5 is installed on the support base 2 through a rotating column 4, and a driving component for driving the rotating column 4 to rotate intermittently is also provided in the support base 2, a side array of the rotating disk 5 is fixedly installed with a plurality of mounting shafts 6, and a frame 7 is rotatably installed at the end of the mounting shaft 6, and a fixing component for fixing the filter is provided in the frame 7, and a fixed seat 8 is provided below the corresponding plurality of frames 7 in the fence 3, and a support frame 9 is fixedly installed at the position of two adjacent frames 7 on the fence 3, and a scanning and leak detection module 10 is installed on the support frame 9, and a round rod 11 is also fixedly installed on the end face of the frame 7, and a gear 12 is fixedly provided on the end of the round rod 11, and an annular groove is provided on the top surface of the fence 3. Gear teeth 13 meshing with gears 12 are provided on one side of the two support frames 9 in the shaped groove. By setting a driving assembly, an installation shaft 6, a round rod 11 and a gear 12, the driving assembly can drive multiple filters installed in the frame 7 to move successively to the bottom of the support frame 9 during the intermittent rotation of the driving disk 5. In conjunction with the scanning leak detection module 10 set on the support frame 9, continuous detection of multiple filters can be achieved. Moreover, in the process of the filter rotating from one of the scanning leak detection modules 10 to the bottom of another scanning leak detection module 10, the engagement of the gear 12 with the gear teeth 13 on the fence 3 can drive the frame 7 to flip together with the filter. In the process of the filter rotating one circle, double-sided detection of the filter can be achieved. Compared with the prior art device that can only perform single-sided detection on the filter, the comprehensiveness and accuracy of the filter scanning leak detection are improved.

[0024] Among them, a roller 14 is also rotatably installed on the round rod 11, and the roller 14 is rollingly installed on one of the side walls of the groove. The setting of the round rod 11 can support the end of the frame 7 away from the rotating disk 5, so that the rotation of the frame 7 is more stable, and the setting of the roller 14 reduces the friction resistance between the round rod 11 and the fence 3, so that the rotation of the frame 7 is smoother.

[0025] Specifically, the fixing assembly includes a pair of clamping units symmetrically arranged in the frame 7, and the clamping unit includes a pair of electric telescopic cylinders 21 fixedly installed in the frame 7 and clamping plates 22 fixedly installed at the telescopic ends of the electric telescopic cylinders 21.

[0026] Preferably, the splint 22 is L-shaped, and a groove is provided on the vertical plate of the splint 22, and a limiting plate 23 is movably inserted into the groove through a plurality of elastic members 24. The width of the limiting plate 23 is smaller than the width of the horizontal plate of the splint 22, and the end face of the limiting plate 23 is a wedge-shaped structure. The arrangement of the groove, the limiting plate 23 and the elastic member 24, in the process of placing the filter in the frame 7 from top to bottom, the wedge-shaped structure of the end face of the limiting plate 23 can automatically limit the top of the filter, which not only facilitates the fixation of the filter, but also prevents the filter from falling from the middle during the flipping of the frame 7, thereby ensuring the stability of the double-sided leak detection of the filter.

[0027] Example 2

[0028] This embodiment describes the driving component in detail based on the first embodiment, specifically:

[0029] See also Figure 3 The driving assembly includes a driving wheel 15, a driven wheel 16 and a brake wheel 17. The driving wheel 15 and the driven wheel 16 are both rotatably arranged in the support seat 2. The driving wheel 15 is driven by a motor, and a shift rod 18 is fixedly installed at an eccentric position on the end face of the driving wheel 15. The driven wheel 16 is coaxially fixedly connected to the rotating column 4, and a plurality of shift grooves 19 are provided on the driven wheel 16 for sliding cooperation with the shift rod 18. The number of the shift grooves 19 is the same as the number of the frame 7. An arc groove is provided between adjacent shift grooves 19. The brake wheel 17 is coaxially fixedly mounted on the driving wheel 15. The brake wheel 17 is fitted with a clearance in the arc groove, and a notch 20 is provided on the brake wheel 17. With the arrangement of the driving assembly, when the driving wheel 15 is driven to rotate one circle, the lever 18 on the driving wheel 15 slides in the slot 19 in the driven wheel 16, which can drive the driven wheel 16 to rotate a specified angle, and cooperate with the brake wheel 17 to fix the driven wheel 16 after rotation. In this process, the frame 7 can be accurately controlled to rotate a specified angle, and the frame 7 can be accurately rotated to the bottom of the two scanning leak detection modules 10, thereby improving the accuracy of filter leak detection.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
