Description

Technical Field

[0001] The utility model relates to the technical field of filter devices, in particular to a seamlessly replaceable high-voltage rectifier inverter cabinet air filter device. Background Art

[0002] High-voltage inverters, excitation rectifier cabinets and other large-capacity, high-voltage rectifier inverter equipment generate huge heat and require multiple high-power cooling fans for forced cooling. The cooling air flow is large and the air pressure is high. The power unit must not accumulate dust or dirt, and no debris can enter the cabinet to cause discharge failures. Therefore, the cabinets of this type of equipment are equipped with air filters to ensure that the cooling air is clean and free of debris, reducing internal dust accumulation.

[0003] At present, high-voltage inverter cabinets, excitation rectifier cabinets and other equipment usually use external filter frames. The filter is placed in the filter slot of the cabinet panel, and the filter is pressed and stuck on the cabinet with a metal frame. Due to the high heat generation, large cooling air flow and high wind pressure of large rectifier inverter equipment such as high-voltage inverters and excitation rectifiers, the air intake filter will gradually be blocked by dust and debris during the operation of the equipment, affecting the cooling of the equipment. It is necessary to replace and flush the filter regularly according to the degree of dirtiness of the filter. In harsh environments, the filter clogging speed increases sharply, sometimes it only takes 3-5 days to be completely blocked, and the filter replacement frequency is very high. When replacing the filter structure currently used, the filter frame needs to be removed, the old filter is taken out, and then the new filter is installed. The replacement method is relatively cumbersome, and there is a risk that dust, debris and other debris will be sucked into the inverter during the replacement process. Utility Model Content

[0013] 1. In the utility model, when air enters the interior of the inverter cabinet, the filter screen filters the air to remove dust and impurities in the air, thereby preventing dust and impurities from entering the interior of the inverter cabinet. When replacing the filter screen, the mounting frame installed in the box body is squeezed by a new mounting frame, and the mounting frame inside the box body gradually withdraws from the box body under squeezing. In the replacement process, the sealing gaskets arranged on the outer walls of the adjacent two sides of the mounting frame seal the contact parts of the two mounting frames to prevent air from leaking from the contact parts of the new and old mounting frames when the mounting frames are replaced.

The cleaning pad inside the cleaning strip wipes the dustproof net to remove the dust impurities attached to its surface, thereby cleaning the dustproof net. The collection groove collects the dust impurities wiped off by the cleaning pad for unified treatment. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] By means of the above structure: when in use, the mounting plate 16 is connected to the outer wall of the inverter cabinet by the fixing bolts 17. When air enters the interior of the inverter cabinet, the filter 18 filters the air to remove dust and impurities in the air to prevent dust and impurities from entering the interior of the inverter cabinet. When replacing the filter 18, the mounting frame 2 installed with the new filter 18 is squeezed against the mounting frame 2 installed in the box body 1. The mounting frame 2 inside the box body 1 gradually withdraws from the box body 1 under squeezing, and during the replacement process, the sealing gaskets 5 arranged on the outer walls of the adjacent two sides of the mounting frame 2 seal the contact parts of the two mounting frames 2 to prevent air from leaking from the contact parts of the new and old mounting frames 2 when the mounting frame 2 is replaced. After the mounting frame 2 is pushed out, since the filter 18 and the magnetic strip 4 are adsorbed by magnetic force, the filter 18 can be replaced by pushing it, which is more convenient to use. Compared with the traditional device, it can realize seamless replacement of the filter components of the high-voltage rectifier inverter cabinet. At the same time, the air can also be filtered during the replacement process, which solves the problem of impurities entering the interior of the inverter cabinet with the air during the replacement of the filter 18.

[0026] like Figure 1 As shown, a dustproof groove is opened on the outer wall of the box body 1, and a dustproof net 7 is installed on the inner wall of the dustproof groove. The aperture of the dustproof net 7 is larger than the aperture of the filter 18. The dustproof net 7 performs preliminary filtration on the air to remove large particles of dust and impurities in the air, thereby reducing the workload of the filter 18. The dustproof net 7 absorbs large particles of impurities, and the filter 18 blocks small particles of impurities. The two cooperate with each other, and the filter 18 is not easy to be blocked.

[0027] Example 2

After the dustproof net 7 has been working for a long time, a large amount of dust and impurities are attached to its outer wall. At this time, the cleaning strip 10 is pushed to slide along the outer wall of the box body 1, and the cleaning pad 11 inside the cleaning strip 10 wipes the dustproof net 7 to remove the dust and impurities attached to its surface, thereby cleaning the dustproof net 7.

The outer wall of the collecting groove 15 close to the connecting groove 14 is provided with a connecting block adapted to the connecting groove 14. The collecting groove 15 collects dust and impurities wiped off by the cleaning pad 11 for unified treatment.

[0030] How this utility works:

[0031] When in use, the mounting plate 16 is connected to the outer wall of the inverter cabinet through the fixing bolts 17. When air enters the interior of the inverter cabinet, the filter 18 filters the air to remove dust and impurities in the air to prevent dust and impurities from entering the interior of the inverter cabinet. When the filter 18 is replaced, the mounting frame 2 installed with the new filter 18 is squeezed against the mounting frame 2 installed in the box body 1 through the mounting frame 2. The mounting frame 2 inside the box body 1 gradually withdraws from the box body 1 under squeezing, and during the replacement process, the sealing gaskets 5 arranged on the outer walls of the adjacent two sides of the mounting frame 2 seal the contact parts of the two mounting frames 2 to prevent air from leaking from the contact parts of the new and old mounting frames 2 when the mounting frame 2 is replaced. After the mounting frame 2 is pushed out, since the filter 18 and the magnetic strip 4 are adsorbed by magnetic force, the filter 18 can be replaced by pushing it, which is more convenient to use. Compared with the traditional device, it can realize seamless replacement of the filter components of the high-voltage rectifier inverter cabinet. At the same time, the air can also be filtered during the replacement process, which solves the problem of impurities entering the interior of the inverter cabinet with the air during the replacement of the filter 18.

[0032] The dust-proof net 7 performs preliminary filtration on the air to remove large dust particles in the air, thereby reducing the workload of the filter 18. The dust-proof net 7 absorbs large impurities and the filter 18 blocks small impurities. The two cooperate with each other, and the filter 18 is not easy to be blocked. After the dust-proof net 7 has worked for a long time, a large amount of dust impurities are attached to its outer wall. At this time, the cleaning strip 10 is pushed to slide along the outer wall of the box body 1. The cleaning pad 11 inside the cleaning strip 10 wipes the dust-proof net 7 to remove the dust impurities attached to its surface, thereby cleaning the dust-proof net 7. The collecting groove 15 collects the dust impurities wiped off by the cleaning pad 11 for unified treatment.
