Description

Technical Field

[0001] The utility model relates to the technical field of air filter element cleaning, in particular to an air filter element cleaning device. Background Art

[0002] There is often a lot of dust and impurities on the surface of the air filter. The traditional manual beating, vibration and compressed air blowing are not only slow in efficiency (it takes about 10 minutes to clean an air filter), but also cause a lot of floating dust in the surrounding working environment, affecting the health of personnel. In large-scale construction sites, there are many vehicles and the working environment is poor. The workload of cleaning the air filter is large. In order to ensure the normal operation of the vehicle, a lot of manpower is required to carry out the cleaning work. Therefore, the traditional cleaning method is not conducive to the health of personnel, the labor cost is high and the efficiency is low.

[0003] The existing Chinese patent document with application number 201520923496.X discloses an air filter cleaning device for an air compressor, comprising: a connecting air pipe, a pressure reducing valve, an upper sealing plate of the air filter, an intermediate purge air pipe, a sealing plate fixing bolt, an air filter body, and an air filter lower sealing plate. The right end of the connecting air pipe is connected to the pressure reducing valve, and the left end of the connecting air pipe is connected to the intermediate purge air pipe. The upper sealing plate and the lower sealing plate of the air filter are arranged on the upper and lower sides of the air filter body via the sealing plate fixing bolts. During cleaning, the air filter body needs to be clamped between the upper and lower sealing plates of the air filter, which is cumbersome to operate and has low work efficiency. In addition, the gas after cleaning the air filter body has no guiding mechanism and flows directly into the air around the air filter body, which pollutes the working environment and is detrimental to the health of the workers.

[0031] Figure 1 and Figure 2 An embodiment of the air filter cleaning device of the present invention is shown. The air filter cleaning device of this embodiment includes a frame 1, a cleaning pipe 2, a filter pipe 3 and a sewage pipe 4. The cleaning pipe 2 and the filter pipe 3 are both installed on the frame 1, one end of the cleaning pipe 2 is connected to one end of the filter pipe 3, and the sewage pipe 4 is connected to the side of the filter pipe 3. The other end of the cleaning pipe 2 is open to form an inlet and outlet 5 for the air filter to enter and exit. The other end of the filter pipe 3 is provided with a sealing plate 32, and the filter pipe 3 is provided with an exhaust mechanism 6 for discharging the gas in the cleaning pipe 2 to the sewage pipe 4.

[0032] During use, the air filter element is first placed into the cleaning pipe 2 through the inlet and outlet 5. Then, air is supplied to the cleaning pipe 2 through the air supply device to clean the air filter element. At the same time, the exhaust mechanism 6 is activated to discharge the air in the cleaning pipe 2 into the sewage pipe 4, and the polluted air is discharged through the sewage pipe 4. Compared with the existing technology, on the one hand, the air filter element can be directly placed in the cleaning pipe 2 without being clamped, which is convenient for operation and improves work efficiency. On the other hand, the polluted air is discharged to a high or distant place through the sewage pipe 4, reducing pollution to the environment in which the workers are located and benefiting their health.

[0033] Furthermore, in this embodiment, the cleaning pipe 2 is arranged horizontally and the sewage pipe 4 is arranged vertically. The horizontal arrangement of the cleaning pipe 2 facilitates the placement and removal of the air filter element. The vertical arrangement of the sewage pipe 4 facilitates the discharge of polluted air to a high or distant place.

[0034] Furthermore, in this embodiment, the cleaning pipe 2 and the filtering pipe 3 are coaxial.

[0035] Furthermore, in this embodiment, the exhaust mechanism 6 includes an exhaust fan 61 and a motor 62. The motor 62 is mounted outside the sealing plate 32, and the fan 61 is disposed within the filter duct 3 and connected to the output shaft of the motor 62. The motor 62 drives the exhaust fan 61 to rotate, exhausting the air from the cleaning duct 2 and pushing it toward the sewage duct 4.

[0036] Furthermore, in this embodiment, the cleaning pipe 2 is a whole pipe, which is convenient for processing and manufacturing.

[0037] Example 2:

[0038] Figure 3 The second embodiment of the air filter cleaning device of the present invention is shown. The structure of this embodiment is basically the same as that of the first embodiment, with the only difference being that the air filter cleaning device also includes an air compressor 7 and an air supply pipe 8. One end of the air supply pipe 8 is connected to the air compressor 7, and the other end is used to supply air into the cleaning pipe 2 to clean the air filter. The air compressor 7 and the air supply pipe 8 constitute an air supply device. Air is supplied to the air supply pipe 8 by the air compressor 7. The air supply pipe 8 can be inserted into the cleaning pipe 2 through the inlet and outlet 5 to clean the air filter.

[0039] Example 3:

[0040] Figure 4 and Figure 5 A third embodiment of the air filter cleaning device of the present invention is shown. The structure of this embodiment is basically the same as that of the first embodiment, with the only difference being that the cleaning duct 2 is composed of an upper half-tube 21 and a lower half-tube 22 that can be opened and closed. The lower half-tube 22 is connected to the filter duct 3 and fixed to the frame 1. The upper half-tube 21 and the lower half-tube 22 are hinged on one side and connected on the other side by a locking member 9. Compared to the cleaning duct 2 of the entire tubular shape, the cleaning duct 2 composed of the upper half-tube 21 and the lower half-tube 22 facilitates opening the upper half-tube 21 to open a long and heavy air filter.

[0041] Furthermore, in this embodiment, an air inlet pipe 31 is provided at one end of the filter duct 3 that connects to the cleaning duct 2. The upper and lower pipes 21 and 22 are disposed outside the air inlet pipe 31. The lower pipe 22 is fixedly connected to the air inlet pipe 31. An opening and closing handle 211 is provided on the outer wall of the upper pipe 21. The cleaning duct 2 connects to the filter duct 3 via the air inlet pipe 31, enhancing the tightness of the connection. Furthermore, a sealing ring may be provided on the outer wall of the air inlet pipe 31 to further enhance the sealing of the connection. An opening and closing handle 211 is provided on the outer wall of the upper pipe 21 to facilitate opening and closing of the upper pipe 21.

[0042] Furthermore, in this embodiment, a blocking plate 212 is provided at one end of the upper half-tube 21, away from the filter duct 3. The blocking plate 212 abuts against the inner side of the lower half-tube 22, and an air inlet connector 213 is provided on the blocking plate 212. On the one hand, after the upper half-tube 21 is opened, the air filter element can be inserted from either the end where the inlet and outlet 5 of the lower half-tube 22 are located, or from above the lower half-tube 22, providing good adaptability. On the other hand, the blocking plate 212 can block the inlet and outlet 5 of the cleaning duct 2, allowing air to enter through the air inlet connector 213 (the air inlet connector 213 can be connected to the air supply duct 8 and can also be inserted into the air supply duct 8). First, this improves the sealing performance of the interior of the cleaning duct 2, which is conducive to improving the cleaning effect of the air filter element. Second, it forces the polluted air to be discharged from the sewage discharge duct 4, further reducing pollution to the working environment.

[0043] Furthermore, in this embodiment, the locking member 9 is a locking screw, and a sealing gasket 23 is provided between both sides of the upper half tube 21 and the lower half tube 22 .
