Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter element cleaning technology, and in particular to a high-pressure air cleaning device for air filters. Background Technology
[0002] Air filters are key components used to filter impurities, particulate matter, and pollutants from the air. They are widely used in automobiles, home appliances, industrial equipment, and other fields. Their core function is to ensure that the air entering the equipment or engine is clean, thereby protecting internal precision components, improving operating efficiency, and extending service life. When the filter surface is covered with dust, airflow is obstructed, and the equipment needs to "inhale" more forcefully, increasing energy consumption, thus requiring cleaning.
[0003] In existing technologies, air filters are typically cleaned using an air gun or by disassembling and replacing them. However, air gun cleaning exposes the air filter to the external environment, causing dust blown out by the air gun to disperse into the air and pollute the environment. Furthermore, the air filter is not firmly fixed when cleaned with an air gun. If the air filter cannot withstand the air sprayed from the air gun and shifts or falls off, the dust on the outside of the air filter will not receive the appropriate force of the air, thus reducing the dust removal quality. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-pressure air cleaning device for air filters.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-pressure air cleaning device for an air filter element, including an installation cabinet, wherein an upper cabinet door and a lower cabinet door are hinged to one side of the installation cabinet, the lower cabinet door is located below the upper cabinet door, a partition is fixedly connected inside the installation cabinet, and a dust removal component is installed inside the installation cabinet. The dust removal assembly includes an air pump, which is fixedly installed inside the mounting cabinet. The output end of the air pump is connected to a connecting pipe, and an electric butterfly valve is installed through the middle of the connecting pipe. One end of the connecting pipe is connected to a high-pressure air storage tank.
[0006] As a further description of the above technical solution: The high-pressure gas storage cylinder is fixedly installed at the bottom of the installation cabinet. The output end of the high-pressure gas storage cylinder is fixedly connected to an air outlet pipe. An electric butterfly valve is connected through the middle of the air outlet pipe. An air outlet head is connected through one end of the air outlet pipe. The air outlet pipe is connected through the middle of the partition.
[0007] As a further description of the above technical solution: A housing rod is fixedly connected to one side of the mounting cabinet. A stepper motor is fixedly installed on the lower surface of the housing rod. A lead screw is fixedly connected to the output end of the stepper motor. An internal threaded post is connected to the external thread of the lead screw, and the internal threaded post is slidably connected inside the housing rod.
[0008] As a further description of the above technical solution: One end of the internally threaded column is fixedly connected to a pressure frame, an air filter element is provided below the pressure frame, a fixing ring is fixedly connected to the upper surface of the partition, and a shell is fixedly connected to the outside of the fixing ring.
[0009] As a further description of the above technical solution: Multiple limiting shells are fixedly connected to the outer wall of the fixed ring, and springs are fixedly connected inside the limiting shells. One end of each spring is fixedly connected to a telescopic column, and one end of each of the two telescopic columns is fixedly connected to a push plate.
[0010] As a further description of the above technical solution: A dust removal assembly is provided on the other side of the installation cabinet. The dust removal assembly includes a housing rod two. A stepper motor two is fixedly installed on the lower surface of the housing rod two. A lead screw two is fixedly connected to the output end of the stepper motor two.
[0011] As a further description of the above technical solution: The external thread of the second lead screw is connected to an internal threaded bracket, which is slidably connected inside the second lead screw. One end of the internal threaded bracket is fixedly connected to a right-angle brush, and the internal threaded bracket is slidably connected to the upper surface of the mounting cabinet. A dust suction pipe is connected through the upper surface of the mounting cabinet.
[0012] This utility model has the following beneficial effects: 1. This utility model, through the setting of the dust removal component, uses the air outlet to easily spray high-pressure gas into the air filter element, thereby facilitating the blowing out of dust in the air filter element using high-pressure gas. The combined ring of multiple push plates helps to push the bottom of the air filter element, so that the air filter element is clamped and pre-positioned. Then, under the pressure of the pressure frame, the air filter element is squeezed and its position is locked. This helps to reduce the phenomenon that the air filter element is displaced due to gas blowing, which would lead to gas leakage and reduce the dust removal quality.
[0013] 2. This utility model, through the setting of the dust removal component, utilizes the downward movement of the right-angle brush to help brush the dust adhering to the inner wall of the installation cabinet, causing it to disperse inside the installation cabinet. Under the suction action of the vacuum cleaner connected to the suction pipe, it helps to suck out the dispersed dust inside the installation cabinet, thereby reducing the difficulty for operators to clean the dust inside the installation cabinet.

[0019] As attached Figure 4 As shown, a housing rod 12 is fixedly connected to one side of the mounting cabinet 1. A stepper motor 13 is fixedly installed on the lower surface of the housing rod 12. A lead screw 16 is fixedly connected to the output end of the stepper motor 13. An internal threaded post 14 is connected to the external thread of the lead screw 16. The internal threaded post 14 has a thread that matches the lead screw 16. The internal threaded post 14 is slidably connected to the inside of the housing rod 12. A pressure frame 15 is fixedly connected to one end of the internal threaded post 14 to facilitate pressing down on the top of the air filter body 17.
[0020] As attached Figure 1 As shown, an air filter element 17 is provided below the pressure frame 15, and a housing 19 is fixedly connected to the outside of the fixing ring 18, which provides protection for the outside of the limiting housing 20.
[0021] As attached Figure 5 As shown, a fixing ring 18 is fixedly connected to the upper surface of the partition 4, which serves to limit the air filter element 17. Multiple limiting shells 20 are fixedly connected to the outer wall of the fixing ring 18. A spring 21 is fixedly connected inside the limiting shell 20. One end of the spring 21 is fixedly connected to a telescopic column 22, which provides elastic pushing force to the telescopic column 22. One end of two of the telescopic columns 22 is fixedly connected to a push plate 23, which facilitates the push plate 23 to push the air filter element 17.
[0022] As attached Figure 6 As shown, a dust removal assembly is provided on the other side of the installation cabinet 1. The dust removal assembly includes a housing rod 24, which protects the lead screw 26. A stepper motor 25 is fixedly installed on the lower surface of the housing rod 24. The output end of the stepper motor 25 is fixedly connected to the lead screw 26, which drives the lead screw 26 to rotate. An internal threaded bracket 27 is connected to the external thread of the lead screw 26. The internal threaded bracket 27 has a thread that matches the lead screw 26. The internal threaded bracket 27 is slidably connected to the inside of the housing rod 24. A right-angle brush 28 is fixedly connected to one end of the internal threaded bracket 27, which facilitates brushing against the inner wall of the installation cabinet 1, allowing dust to disperse. The internal threaded bracket 27 is slidably connected to the upper surface of the installation cabinet 1.
[0023] As attached Figure 3 As shown, a vacuum pipe 29 is connected through the upper surface of the mounting cabinet 1 for connecting a vacuum cleaner.
[0024] Working principle: In use, first connect the suction pipe 29 to the external vacuum cleaner, then open the multiple push plates 23 and place the air filter 17 between the push plates 23. At this time, the air filter 17 will be outside the air outlet 11, and the bottom of the air filter 17 will be pushed and clamped by the push plates 23 under the action of multiple springs 21 pushing the telescopic column 22 and thus pushing the push plates 23. Then, the external controller controls the start of the stepper motor 13, so that its output end drives the lead screw 1. When screw 16 rotates, it will be pulled back by the internal thread of the internal threaded column 14, causing the internal threaded column 14 to slide inside the shell rod 12. This will cause the pressure frame 15 to slide down on the upper surface of the mounting cabinet 1. At this time, the bottom of the pressure frame 15 will press against the top of the air filter body 17. Under the action of the clamping force, the air filter body 17 will be limited and locked. Then, the opening of the electric butterfly valve 7 will be controlled to start the inflation process of the high-pressure air tank 8. When the air pressure in the high-pressure air tank 8 reaches a certain level, the pressure will increase. When the preset threshold is reached, the electric butterfly valve 7 is immediately closed. During this process, it is crucial to ensure the chassis door is tightly closed to maintain airtightness. Then, the electric butterfly valve 10 is opened, and the instantaneous high-pressure gas acts on the air filter, creating a cold-explosion effect that blows out the attached dust. After the high-pressure air tank 8 is refilled with gas, the gas is released again to continue the cold-explosion process on the air filter, expelling the dust from the air filter body 17. Finally, the external vacuum cleaner is turned on, utilizing the suction power connected to the vacuum cleaner... Dust pipe 29 sucks out the floating dust inside the installation cabinet 1. At the same time, stepper motor 25 is started. When the output end of stepper motor 25 drives lead screw 26 to rotate, it will drive the internal thread frame 27 to move downward. The internal thread frame 27 will drive the right-angle brush 28 to move downward. As the right-angle brush 28 moves downward, it will brush the dust on the inner wall of the installation cabinet 1 and make it float. Then it will be sucked out by dust pipe 29, which helps to reduce the dust content inside the installation cabinet 1. After that, the cabinet door is opened, the limit of the air filter 17 is released and it can be taken out.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
