Description

[0001] The invention relates to the technical field of air compressor filters, and in particular to a filter element anti-blocking type air compressor oil-water filter. Background Art

[0002] During the air compressor's air compression process, lubricants and other substances inevitably enter the compressed air. Oil-water filters, through their internal filter elements, effectively intercept and absorb moisture, oil droplets, and oil mist in the compressed air, thereby reducing the oil and water content in the compressed air, ensuring the cleanliness of the output air and preventing moisture and other substances from corroding subsequent equipment or affecting product quality. This is particularly important for industries with strict air quality requirements, such as electronics, food, and medicine. The use of oil-water filters can significantly reduce the occurrence of such failures, improve equipment operational stability and reliability, and enhance product quality.

[0003] As the purification work is carried out, impurities such as oil and dirt on the filter element will gradually increase. In particular, some oil and dirt will solidify on the filter element, causing the filter mesh to become blocked or semi-blocked, thereby affecting the purification efficiency of the filter element. Most of the current air compressor oil-water filters do not have filter element dredging facilities, resulting in the need for manual disassembly, cleaning or replacement of the filter element on a regular basis, which increases the workload of users.

[0029] The following will refer to Figures 1 to 12 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0030] A filter element anti-blocking type air compressor oil-water filter, such as Figure 1-Figure 3As shown, it includes a housing 1 and a filter element 5. An annular partition 2 is provided in the housing 1. The annular partition 2 divides the space inside the housing 1 into a filter chamber 3 and an exhaust chamber 4. The filter chamber 3 is located above the exhaust chamber 4. A spiral rack 9 is detachably provided on one side of the annular partition 2 close to the filter chamber 3. The filter element 5 can be rotatably installed inside the spiral rack 9. In this embodiment, the housing 1 is composed of two upper and lower cylinders, and the two cylinders are connected by threads. The spiral rack 9 is detachably provided, which is convenient for users to replace the filter element 5. The filter element 5 is set to be conical, and the spiral rack 9 is detachable. The shape of the frame 9 matches the filter element 5. The spiral frame 9 includes a connecting ring, which is threadedly connected to the annular partition 2. A spiral blade is provided at the bottom of the connecting ring, and a support plate is provided at the bottom of the spiral blade. The support plate is rotatably connected to the bottom of the filter element 5; a connecting seat 6 is provided on one side of the shell 1, and a first channel 7 and a second channel 8 are provided on the connecting seat 6. The first channel 7 is fluidically connected to the exhaust chamber 4, and the second channel 8 is fluidically connected to the filter chamber 3. The first channel 7 is connected to the air supply pipeline of the external production equipment, and the second channel 8 is connected to the gas output pipeline of the air compressor.

[0031] The air compressor inputs high-pressure air into the interior of the filter chamber 3 through the second channel 8. The air is filtered by the filter element 5 and then enters the exhaust chamber 4 (the filter element 5 is used to intercept or absorb impurities such as moisture, oil, etc. in the air), and finally supplies air to the external production equipment through the first channel 7.

[0032] By setting the filter element 5 to be conical, when the height of the filter element 5 is at a rated value, the filtration area can be increased, thereby improving the air purification efficiency of the device.

[0033] A plunger reversing mechanism for gas injection reversing is installed in the connecting seat 6, and the first channel 7 and the second channel 8 are both matched with the plunger reversing mechanism; a rotary drive mechanism is installed on the housing 1, and the filter element 5 and the plunger reversing mechanism are both driven and cooperated with the rotary drive mechanism; when the rotary drive mechanism drives the filter element 5 to rotate, the spiral blades can scrape off impurities on the surface of the filter element 5 to prevent the purification effect of the device from being affected by the blockage of the filter element 5.

[0034] like Figure 2 、 Figure 4-Figure 6 、 Figures 8-10As shown, the plunger reversing mechanism includes a first plunger assembly and a second plunger assembly, and the first plunger assembly and the second plunger assembly are driven to cooperate; the first plunger assembly includes a first plunger 10 rotatably mounted inside the connecting seat 6, the first channel 7 matches the first plunger 10, and a flow channel 11 is provided in the first plunger 10, and the two openings of the flow channel 11 are respectively opening a and opening b, and the cross-section of opening b is set to be fan-shaped; a first rotating shaft 12 is coaxially provided on the top of the first plunger 10, the top end of the first rotating shaft 12 passes through the connecting seat 6 and the end thereof is coaxially fixedly connected to the first gear 13, and a first torsion spring 14 is sleeved on the first rotating shaft 12 between the connecting seat 6 and the first gear 13; when the first plunger 10 rotates, the positions of opening a and opening b can be adjusted to adapt to different working states of the device.

[0035] like Figure 2 、 Figure 5-Figure 7 、 Figure 11 and Figure 12 As shown, the second plunger assembly includes a second plunger 15 rotatably mounted in the connecting seat 6, the second channel 8 matches the second plunger 15, and a T-shaped channel 33 is provided on the second plunger 15. The bottom of the second plunger 15 is coaxially fixedly connected to the second rotating shaft 16, and the second rotating shaft 16 is fixedly connected to a limiting block 17. An arc-shaped limiting groove 18 is provided on the connecting seat 6, and the limiting block 17 extends into the arc-shaped limiting groove 18 and can rotate around the second rotating shaft 16 as the axis. In this embodiment, the limiting block 17 is restricted by the arc-shaped limiting groove 18 and can only rotate 90 degrees; when the second plunger 15 rotates, the positions of the opening c, opening d and opening e can be adjusted to adapt to different working states of the device.

[0036] like Figure 5 and Figure 6 As shown, a connecting pipe 19 is coaxially provided at the bottom of the first plunger 10, and the flow channel 11 is in fluid communication with the connecting pipe 19. The other end of the connecting pipe 19 is attached to the top of the second plunger 15 and a first vent 20 is provided at the end thereof. A second vent 21 matching the first vent 20 is provided at the top of the second plunger 15, and the T-channel 33 is in fluid communication with the second vent 21. In the initial state, the first vent 20 and the second vent 21 are not aligned. When the first plunger 10 rotates 45 degrees relative to the second plunger 15, the first vent 20 is aligned with the second vent 21. At this time, the flow channel 11 is in communication with the interior of the T-channel 33 through the connecting pipe 19. A second torsion spring 24 is sleeved on the connecting pipe 19 between the first plunger 10 and the second plunger 15.

[0037] like Figure 2 and Figure 3As shown, the rotary drive mechanism includes a central shaft 22 that passes through and is rotatably connected to the top wall of the shell 1. A fitting block 23 is provided on one end of the central shaft 22 extending into the shell 1. A fitting groove is coaxially provided on the filter element 5, and the fitting block 23 is engaged with the fitting groove. A protective cover 25 is provided on the top of the shell 1, and a motor 26 is installed on the protective cover 25. The motor 26 is a servo motor and can realize forward and reverse rotation. In this embodiment, a reducer is provided on the output end of the motor 26, and the reducer is not drawn; the output end of the motor 26 is coaxially fixedly connected to the other end of the central shaft 22, and a second gear 28 is coaxially fixedly connected to the central shaft 22 between the shell 1 and the protective cover 25; when the motor 26 drives the central shaft 22 to rotate, the filter element 5 rotates slowly through the cooperation of the fitting block 23 and the fitting groove.

[0038] like Figure 2 and Figure 4 As shown, it also includes a rack 27, the first gear 13 and the second gear 28 are both engaged with the rack 27, a positioning base 29 is fixedly connected to the top of the shell 1, and a slide rail 30 is fixedly connected to the rack 27, and the slide rail 30 is slidably matched with the positioning base 29. Through the matching setting of the positioning base 29 and the slide rail 30, the rack 27 can move along the direction of the slide rail 30; when the central shaft 22 rotates, the second gear 28 rotates synchronously with the central shaft 22, thereby driving the rack 27 to slide along the direction of the slide rail 30, thereby driving the first gear 13 to rotate.

[0039] like Figure 2 As shown, air pressure sensors 31 are installed in the filter chamber 3 and the exhaust chamber 4. The air pressure sensors 31 are used to monitor the air pressure intensity inside the filter chamber 3 and the exhaust chamber 4 respectively. A single-chip microcomputer is installed on the shell 1. The two air pressure sensors 31 are electrically connected to the single-chip microcomputer. A solenoid valve 32 is installed at the bottom of the shell 1. A heating wire 34 is installed in the exhaust chamber 4. The motor 26, the solenoid valve 32 and the heating wire 34 are all electrically connected to the single-chip microcomputer.

[0040] Working principle of this device: In the initial state, the first channel 7 and the second channel 8 are both closed. Figure 9 and Figure 12 , at this time, openings a, b, c and e are all blocked, and opening d is in a state corresponding to the input end of the second channel 8; when the device is working, the motor 26 drives the central shaft 22 to rotate slowly counterclockwise, the second gear 28 rotates synchronously with the central shaft 22, the rack 27 slides and drives the first gear 13 to rotate counterclockwise, causing the first plunger 10 to rotate 90 degrees counterclockwise (because the motor 26 is a servo motor, the rotation angle of the first plunger 10 can be controlled by controlling the rotation amount of the motor 26), so that Figure 8As the first channel 7 is opened, both opening a and opening b correspond to the first channel 7. As the second torsion spring 24 is connected to the first plunger 10 and the second plunger 15 at both ends, when the first plunger 10 rotates counterclockwise, the second plunger 15 will be driven to rotate synchronously. That is, the second plunger 15 rotates 90 degrees counterclockwise to Figure 11 At this time, both opening c and opening e correspond to the second channel 8, and opening d is closed, that is, the second channel 8 is in an open state.

[0041] After the first channel 7 and the second channel 8 are opened, the air compressor inputs high-pressure air into the interior of the filter chamber 3 through the second channel 8. The air is filtered by the filter element 5 and enters the interior of the exhaust chamber 4. Finally, the air is supplied to the external production equipment through the first channel 7, thereby realizing the air purification function of the device.

[0042] As the purification work of this device is running, impurities such as oil and dirt on the filter element 5 gradually increase, causing the mesh of the filter element 5 to become blocked or semi-blocked, thereby affecting the purification efficiency of this device; since the two air pressure sensors 31 respectively monitor the gas pressure in the filter chamber 3 and the exhaust chamber 4 in real time, when the pressure difference in the filter chamber 3 and the exhaust chamber 4 is too large (the specific pressure difference is set according to demand), it proves that the filter element 5 is seriously blocked at this time, and the single-chip microcomputer controls the motor 26 to continue to rotate clockwise, the solenoid valve 32 to open, and the heating wire 34 to heat.

[0043] When the motor 26 rotates, the driving center shaft 22 rotates clockwise, the second gear 28 rotates synchronously and drives the rack 27 to slide in the opposite direction, the first gear 13 drives the first plunger 10 to rotate clockwise, and at the same time the first torsion spring 14 accumulates force, and the rack 27 disengages from the second gear 28 when it slides to the limit. At this time, the rotation angle of the first plunger 10 is 135 degrees. Figure 2 and Figure 10 At this time, the opening a is closed, and the opening b is connected to the end of the first channel 7 close to the exhaust chamber 4.

[0044] When the first plunger 10 rotates clockwise, the second plunger 15 rotates along with the first plunger 10. Restricted by the arc-shaped limiting groove 18, the second plunger 15 can only rotate 90 degrees clockwise. When the first plunger 10 rotates 135 degrees clockwise, the first plunger 10 rotates 45 degrees relative to the second plunger 15 (at the same time, the second torsion spring 24 accumulates force), so that the first vent 20 is aligned with the second vent 21. At this time, the flow channel 11 is connected to the interior of the T-channel 33 through the connecting pipe 19. Figure 12 At this time, the opening c and the opening e are both blocked, and the opening d is connected to the input end of the second channel 8.

[0045] The air compressor injects high-pressure air into the T-channel 33 through the input end of the second channel 8. The gas passes through the connecting pipe 19, the flow channel 11, the first channel 7, and the exhaust chamber 4 in sequence. The gas is heated by the electric heating wire 34 and then input into the interior of the filter element 5. After passing through the mesh of the filter element 5, the gas enters the filter chamber 3 and is finally discharged from the solenoid valve 32. When the gas passes through the mesh of the filter element 5, it can flush out the impurities in the mesh of the filter element 5, thereby achieving the purpose of unblocking the filter element 5.

[0046] When the motor 26 rotates the central shaft 22 continuously in the clockwise direction, the filter element 5 rotates slowly and continuously, and the spiral blades can scrape off the impurities on the surface of the filter element 5 to prevent the purification efficiency of the device from being affected by clogging of the filter element 5.

[0047] It should be noted that, since the impurities contain oil and other substances, which have a high viscosity, this device heats the gas, that is, heats the oil on the filter element 5, which can improve the fluidity of the oil, thereby facilitating the removal of the oil. However, after the fluidity of the oil is improved, it is easy to flow downward along the surface of the filter element 5, thereby contaminating the lower part of the filter element 5. The setting of the spiral blade can effectively curb the downward flow of the oil, and cooperate with the scraping work of the spiral blade to quickly scrape off the oil.

[0048] After the device has finished clearing the filter element 5, the motor 26 drives the central shaft 22 to rotate counterclockwise. Under the influence of the reset force of the first torsion spring 14, the first gear 13 rotates counterclockwise to reset, causing the rack 27 to slide and re-engage with the second gear 28, and the first plunger 10 rotates counterclockwise to reset, and the second plunger 15 rotates counterclockwise to reset.

[0049] It should be noted that in the description of the present invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
