Technical Field

[0001] This utility model relates to an L-shaped vacuum filter and belongs to the field of vacuum filter technology. Background Technology

[0002] Vacuum filters can collect pollutants drawn in from the atmosphere to prevent system contamination. However, after long-term use, existing L-type vacuum filters accumulate a large amount of dust and other debris on the filtration mechanism, which can cause blockages and affect the normal operation of the device, resulting in a shorter lifespan for the vacuum filter.

[0003] In the prior art, such as the novel L-type filter with application number 202221748899.1, the filter housing and filter element are detachably connected, making it more convenient to use, easier to disassemble, and simpler to maintain. Its structure is simple, and the handle makes it easier to carry. Furthermore, the sealing ring provides better leak prevention, making it more hygienic and environmentally friendly. However, it still requires disassembly for cleaning, making the cleaning process relatively complex. Utility Model Content

[0004] The purpose of this invention is to provide an L-shaped vacuum filter that facilitates the cleaning of the filter mechanism inside the vacuum filter, thereby preventing clogging and improving the service life of the device, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an L-shaped vacuum filter, comprising an L-shaped channel, with flanges fixedly provided at both the inlet and outlet ends of the L-shaped channel, a baffle plate fixedly provided inside the L-shaped channel, a filter screen fixedly provided at the lower part of the side of the baffle plate near the outlet end, an adjusting screw rotatably embedded at the top of the L-shaped channel, the bottom end of the adjusting screw extending into the L-shaped channel, a support plate threaded onto the adjusting screw, a first baffle plate fixedly provided at the bottom of one side of the support plate, and connecting rods symmetrically fixedly provided at the bottom of the other side of the support plate, the bottom end of the connecting rods extending below the baffle plate and fixedly connected to a second baffle plate, the side of the second baffle plate away from the first baffle plate closely abutting against the inner wall of the side adjacent to the L-shaped channel, an inlet pipe fixedly provided at the top of one side of the horizontal portion of the L-shaped channel, and a drain hole penetrating through the upper part of the vertical portion of the L-shaped channel near the second baffle plate.

[0006] As a further optimization, the top of the L-shaped channel is provided with a groove that matches the rotating head on the adjusting screw.

[0007] As a further optimization, the top of the rotating head on the adjusting screw is provided with an internal hexagonal groove, which makes it easy to rotate the adjusting screw with a tool.

[0008] As a further optimization, a threaded sleeve matching the adjusting screw is fixedly embedded through the support plate.

[0009] As a further optimization, sealing strips are fixedly provided around the outer walls of both the first and second baffles.

[0010] As a further optimization, the outer wall of the intake pipe is threaded around it to facilitate the use of a connector to fix the air supply pipe to the intake pipe 10.

[0011] As a further optimization, a valve is fixedly installed at the lower part of the vertical section of the L-shaped channel.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a first baffle, a second baffle, and a drain hole, during use, rotating the adjusting screw causes the supporting plate to move upward. At this time, the supporting plate will drive the first baffle to move upward, and simultaneously, the supporting plate will drive the second baffle to move upward until it contacts the baffle through the connecting rod. The L-shaped channel is then closed by the valve, and high-pressure air is delivered into the L-shaped channel through the air inlet pipe, thereby blowing air in the reverse direction onto the filter screen, which blows up the residual dirt on the filter screen and discharges it through the drain hole. This utility model can facilitate the cleaning of the filtration mechanism inside the vacuum filter, thereby avoiding clogging of the device and improving the service life of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] An L-shaped vacuum filter includes an L-shaped channel 1. Flanges 2 are fixedly installed at both the inlet and outlet ends of the L-shaped channel 1. A baffle 3 is fixedly installed inside the L-shaped channel 1. A filter screen 4 is fixedly installed on the lower part of the side of the baffle 3 near the outlet end. An adjusting screw 5 is rotatably embedded at the top of the L-shaped channel 1. The bottom end of the adjusting screw 5 extends into the L-shaped channel 1. A support plate 6 is threaded onto the adjusting screw 5. A first baffle 7 is fixedly installed at the bottom end of one side of the support plate 6. A connecting rod 8 is symmetrically fixed at the bottom end of the other side of the support plate 6. The bottom end of the connecting rod 8 extends below the baffle 3 and is fixedly connected to a second baffle 9. The side of the second baffle 9 away from the first baffle 7 is in close contact with the inner wall of the side adjacent to the L-shaped channel 1. An inlet pipe 10 is fixedly installed at the top of one side of the horizontal portion of the L-shaped channel 1. A drain hole 11 is opened through the upper part of the vertical portion of the L-shaped channel 1 near the second baffle 9.

[0023] Specifically, the top of the L-shaped channel 1 is provided with a groove 12 that matches the rotating head on the adjusting screw 5. The top of the rotating head on the adjusting screw 5 is provided with an internal hexagonal groove. A threaded sleeve that matches the adjusting screw 5 is fixedly embedded in the support plate 6. By providing the groove 12, the rotating head of the adjusting screw 5 can be prevented from protruding out of the L-shaped channel 1. By providing the internal hexagonal groove, it is convenient to use tools to rotate the adjusting screw 5. By providing the threaded sleeve, the adjusting screw 5 can drive the support plate 6 to move up and down.

[0024] Specifically, the outer wall of the air intake pipe 10 is threaded, and the lower part of the vertical section of the L-shaped channel 1 is fixedly equipped with a valve 13. By setting the valve 13, the L-shaped channel 1 can be closed. By setting the thread on the outer wall of the air intake pipe 10, it is convenient to use a connector to fix the air supply pipe to the air intake pipe 10.

[0025] Example 2

[0026] The difference between this embodiment and embodiment 1 is that sealing strips are fixedly provided around the outer walls of the first baffle 7 and the second baffle 9. By setting the sealing strips, the sealing performance between the first baffle 7, the second baffle 9 and the device can be improved.

[0027] The working principle of this utility model is as follows: In use, the device is fixed to the equipment by flange 2. Air enters through the air inlet of L-shaped channel 1 and is filtered by filter screen 4 before entering the equipment. When it is necessary to clean filter screen 4, the adjusting screw 5 is rotated, which causes the adjusting screw 5 to move the support plate 6 upward. At this time, the support plate 6 will move the first baffle 7 upward. At the same time, the support plate 6 moves the second baffle 9 upward through the connecting rod 8 until it contacts the baffle 3. The L-shaped channel 1 is then closed by valve 13. High-pressure air is then delivered into the L-shaped channel 1 through the air inlet pipe 10, which blows air in the opposite direction onto the filter screen 4, thereby blowing away the residual dirt on the filter screen 4 and discharging it through the drain hole 11. By setting a sealing strip, the sealing between the first baffle 7, the second baffle 9 and the device can be improved.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
