The cleaned dust is automatically discharged through the dust discharge groove at the support ring.

Description

Technical Field

[0001] This invention relates to the field of air compressor technology, and more specifically to an air compressor intake device. Background Technology

[0002] When an air compressor compresses air, the air intake needs to be filtered to avoid affecting the internal components of the air compressor.

[0003] For example, publication number CN211737399U discloses an air intake device for an air compressor, including an air inlet connected to a filter screen. A support rod is connected inside the air inlet, and a connecting rod passes through the middle of the support rod. An electromagnet is connected to one side of the support rod, and a sealing plate is connected to one end of the connecting rod. A spring is wound around the outer wall of the connecting rod. The length of the filter screen is greater than the width of the air inlet. In this invention, the filter screen is connected to the air inlet, allowing the filter screen to be opened for easy cleaning, preventing clogging, reducing the volume of gas passing through the filter screen per unit time, and affecting the efficiency of compressed air. Furthermore, the filter screen can only intercept larger dust particles and cannot filter small dust particles. Adding a water storage tank allows for the adsorption of dust in the air.

[0004] The aforementioned patent allows for easy cleaning of the filter screen by opening it, thus preventing clogging. However, the filter screen lacks an automatic cleaning device and requires regular manual cleaning. Additionally, when the air compressor intake valve plate is damaged, oil spraying can easily occur, causing damage to the filter screen and wasting oil. Summary of the Invention

An intake shroud is fixedly mounted on the top of the support ring. A protective core is mounted on the top of the inner extension ring, and a filter element is sleeved around the protective core. A top plate is fixedly mounted on the top of the protective core, and a top cover is fixedly mounted on the top of the intake shroud. An anti-spraying component is installed inside the intake pipe. The anti-spraying component includes a mounting bracket, and a hollow rod is inserted into the mounting bracket. The bottom of the hollow rod is fixedly connected to... The device has a hollow cylinder, with a blowout preventer plate fixedly connected to the top of the hollow rod. The top cover is equipped with a jet dust removal assembly, which includes a rotating tube. A blade is fixedly fitted on the outside of the rotating tube. A fixed horizontal tube is fixedly fitted on one side of the rotating tube. A fixed vertical tube is fixedly connected to the bottom of the fixed horizontal tube. Multiple jet holes are opened on one side of the fixed vertical tube. A fixed tube is provided at the top of the rotating tube. A rotating tube connector is fitted on the outside of the rotating tube and the fixed tube. A fixed air pipe is fixedly connected to one end of the fixed tube. A nozzle is fixedly connected to the bottom of the fixed air pipe.

[0008] Preferably, the air pressure channel is connected to the air chamber, and an air inlet is fixedly connected inside the air pressure channel.

[0009] Preferably, the intake valve mechanism includes a spring, the bottom of which is fixedly connected to the bottom of the air chamber, a piston plate is fixedly provided on the top of the spring, the piston plate is disposed inside the air chamber and slidably connected to the air chamber, a piston rod is fixedly provided on the top of the piston plate, the top of the piston rod extends out of the air chamber and slidably connected to the top of the air chamber, and an intake valve plate is fixedly provided on the top of the piston rod.

[0010] Preferably, the support ring has multiple dust discharge grooves inside.

[0011] Preferably, the bottom of the filter element is sleeved outside the inner extension ring and slidably connected to the inner extension ring, and the top of the filter element is in contact with the bottom of the top plate.

[0012] Preferably, the hollow rod passes through the fixing frame and is slidably connected to the fixing frame, the fixing frame is fixedly installed inside the air intake pipe, and the diameter of the blowout preventer plate is larger than the diameter of the inner ring of the inner extension ring.

[0013] Preferably, one end of the nozzle extends into the interior of the top cover and is fixedly connected to the top cover.

[0014] Preferably, the fixed tube and the rotating tube are movably connected via a rotating tube joint.

[0015] Preferably, the rotating tube passes through the top cover and is connected to the top cover via a bearing, and the bottom of the rotating tube is connected to the top of the top plate via a bearing.

[0016] The embodiments of the present invention have the following advantages:

[0017] 1. Air enters the fixed air tube and flows into the nozzle and the fixed tube. The air blown out by the nozzle drives the blade to rotate, which in turn drives the rotating tube to rotate. The rotation of the rotating tube drives the fixed vertical tube to rotate through the fixed horizontal tube. At the same time, the air that flows into the fixed tube enters the rotating tube, passes through the fixed horizontal tube and enters the fixed vertical tube. Then, it is blown out of the air jet hole to the outside of the filter element, automatically cleaning the dust trapped on the outside of the filter element. The cleaned dust is automatically discharged through the dust discharge groove at the support ring.

[0018] 2. The intake valve plate is prone to damage due to frequent opening and closing during the start-up of the air compressor. The oil inside the air compressor flows into the intake pipe through the gap between the intake valve plate and the valve chamber. When the oil comes into contact with the hollow cylinder, the hollow cylinder moves upward due to buoyancy. The hollow rod causes the blowout preventer plate to fit against the bottom of the inner ring, thereby blocking the intake pipe, preventing oil from spraying out and causing waste, and at the same time preventing oil from seeping into the filter element and causing damage to the filter element.

[0030] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] See attached document Figure 1 -Appendix Figure 8 The present invention provides an air compressor intake device, including an intake valve body 1, an intake valve body 1 having a valve chamber 2, an intake channel 3, an air chamber 4, and an air pressure channel 5 inside the intake valve body 1, an intake valve mechanism inside the intake valve body 1, and an intake protection mechanism on the top of the intake valve body 1.

[0032] The intake protection mechanism includes an intake pipe 11, which is fixedly mounted on the top of the intake valve body 1. An inner extension ring 12 is fixedly mounted on the top of the intake pipe 11, and a support ring 13 is fixedly mounted on the outside of the intake pipe 11. An intake shroud 14 is fixedly mounted on the top of the support ring 13. A protective core 15 is mounted on the top of the inner extension ring 12, and a filter element 18 is sleeved on the outside of the protective core 15. A top plate 16 is fixedly mounted on the top of the protective core 15, and a top cover 17 is fixedly mounted on the top of the intake shroud 14. An anti-spraying component is provided inside the intake pipe 11. The anti-spraying component includes a fixing frame 19, and a hollow rod 20 is inserted into the fixing frame 19. A hollow rod 20 is fixedly connected to the bottom of the hollow rod 20. The top of the cylinder 21 and hollow rod 20 is fixedly connected to the anti-blowout valve plate 22. The top cover 17 is equipped with a jet dust removal assembly, which includes a rotating tube 26. The rotating tube 26 is fixedly fitted with a blade 31. A fixed horizontal tube 28 is fixedly fitted on one side of the rotating tube 26. A fixed vertical tube 29 is fixedly connected to the bottom of the fixed horizontal tube 28. Multiple jet holes 30 are opened on one side of the fixed vertical tube 29. A fixed tube 25 is provided at the top of the rotating tube 26. A rotating tube connector 27 is fitted on the outside of the rotating tube 26 and the fixed tube 25. A fixed air pipe 23 is fixedly connected to one end of the fixed tube 25. A nozzle 24 is fixedly connected to the bottom of the fixed air pipe 23.

[0033] In this embodiment, to achieve automatic cleaning of the multi-filter air element and prevent oil spraying when the intake valve plate 10 is damaged, when the filter element 18 needs cleaning, air enters the fixed air pipe 23, causing the air to flow into the nozzle 24 and the fixed pipe 25. The air blown out by the nozzle 24 drives the blade 31 to rotate, which in turn drives the rotating pipe 26 to rotate. The rotation of the rotating pipe 26 drives the fixed vertical pipe 29 to rotate through the fixed horizontal pipe 28. At the same time, the air that flowed into the fixed pipe 25 enters the rotating pipe 26, passes through the fixed horizontal pipe 28, enters the fixed vertical pipe 29, and is then blown onto the filter element 18 through the jet nozzle 30. Externally, the dust intercepted on the outside of the filter element 18 is automatically cleaned, and the cleaned dust is automatically discharged through the dust discharge groove at the support ring 13. Since the intake valve plate 10 is frequently opened and closed with the start of the air compressor, it is easily damaged. The oil inside the air compressor flows into the intake pipe 11 through the gap between the intake valve plate 10 and the valve chamber 2. When the oil comes into contact with the hollow cylinder 21, the hollow cylinder 21 moves upward due to buoyancy. The hollow rod 20 makes the blowout preventer plate 22 fit with the bottom of the inner extension ring 12, thereby sealing the intake pipe 11 to prevent the oil from spraying out and causing waste, and at the same time prevent the oil from seeping into the filter element 18 and causing damage to the filter element 18.

[0034] To achieve unidirectional flow of the medium inside the intake valve body 1, the device employs the following technical solution: The pressure channel 5 is connected to the air chamber 4. An intake nozzle 6 is fixedly connected inside the pressure channel 5. The intake valve mechanism includes a spring 7, with its bottom fixedly connected to the bottom of the air chamber 4. A piston plate 8 is fixedly mounted on the top of the spring 7, located inside the air chamber 4 and slidably connected to it. A piston rod 9 is fixedly mounted on the top of the piston plate 8, extending out of the air chamber 4 and slidably connected to it. An intake valve plate 10 is fixedly mounted on the top of the piston rod 9. During intake, a pneumatic device forces air through the intake nozzle 6 and pressure channel 5 into the air chamber 4, causing the piston plate 8 to move downwards. This movement of the piston plate 8 causes the spring 7 to contract. Simultaneously, the piston rod 9 drives the intake valve plate 10 to move downward and disengage from the top of the valve chamber 2, allowing air to flow inside the intake valve body 1. At the same time, the air compressor draws in air, which is drawn into the intake pipe 11 through the intake cover 14, filter element 18, and protective core 15. Under normal conditions, the weight of the hollow rod 20, hollow cylinder 21, and blowout preventer plate 22 causes the blowout preventer plate 22 to be disengaged from the bottom of the inner extension ring 12, which does not affect the gas flow during intake. The inflowing air enters the air compressor head through the valve chamber 2 and intake channel 3. When the air compressor stops working, it stops pressurizing the air chamber 4. The spring force of the spring 7 causes the piston plate 8 to move upward, thereby causing the intake valve plate 10 to seal the top of the valve chamber 2, achieving the purpose of one-way flow of the medium.

[0035] In order to achieve the purpose of automatic dust discharge, the device adopts the following technical solution: multiple dust discharge grooves are opened inside the support ring 13, the bottom of the filter element 18 is sleeved on the outside of the inner extension ring 12 and slidably connected to the inner extension ring 12, the top of the filter element 18 is in contact with the bottom of the top plate 16, and air is blown to the outside of the filter element 18 through the jet hole 30 to automatically clean the dust intercepted on the outside of the filter element 18. At the same time, the cleaned dust is automatically discharged through the dust discharge groove at the support ring 13.

[0036] To prevent oil spraying, the device employs the following technical solution: a hollow rod 20 passes through a fixed frame 19 and is slidably connected to the fixed frame 19. The fixed frame 19 is fixed inside the air intake pipe 11. The diameter of the anti-spray valve plate 22 is larger than the inner diameter of the inner ring 12. When the oil comes into contact with the hollow cylinder 21, the hollow cylinder 21 moves upward due to buoyancy. The hollow rod 20 causes the anti-spray valve plate 22 to fit against the bottom of the inner ring 12, thereby blocking the air intake pipe 11 and preventing oil from spraying out and causing waste.

[0037] To achieve the goal of controlling the rotation of the rotating tube 26 without affecting the air intake of the fixed tube 25 into the rotating tube 26, the device employs the following technical solution: one end of the nozzle 24 extends into the top cover 17 and is fixedly connected to the top cover 17; the fixed tube 25 and the rotating tube 26 are movably connected through a rotating tube joint 27; the rotating tube 26 passes through the top cover 17 and is connected to the top cover 17 through a bearing; the bottom of the rotating tube 26 is connected to the top of the top plate 16 through a bearing; air enters the fixed air tube 23, causing the air to flow into the nozzle 24 and the fixed tube 25; the air blown out by the nozzle 24 drives the blade 31 to rotate; the blade 31 drives the rotating tube 26 to rotate; and the rotating tube 26 rotates along the fixed tube 25 through the rotating tube joint 27. The rotating pipe 26 is connected to the fixed pipe 25 through the rotating pipe joint 27 (the high-speed rotating joint is specially designed for water, hot oil, compressed air or low-pressure steam under high-speed conditions. In order to resist the wear of various hard impurities and abrasive particles that enter with the medium, the main sealing components of this product are all made of imported sealing materials. The rotating body adopts a special treatment process to prevent wear and corrosion. At the same time, two imported Swedish high-precision bearings support the entire copper shell, so that it can operate stably for a long time without leakage at a speed of 2000RPM). This does not affect the rotation of the rotating pipe 26. The rotation of the rotating pipe 26 drives the rotation of the fixed vertical pipe 29 through the fixed horizontal pipe 28, and at the same time, the air flowing into the fixed pipe 25 enters the interior of the rotating pipe 26.

[0038] The usage process of this invention is as follows: When using this invention, the air inlet 6 is connected to a pneumatic device, and the fixed air pipe 23 is connected to the air inlet device or the air compressor outlet pipe, so that part of the compressed air produced by the air compressor can be used for automatic cleaning of the filter element 18. During use, the air inlet valve body 1 is connected to the air compressor head. When air is inlet, the pneumatic device causes air to enter the air chamber 4 through the air inlet 6 and the air pressure channel 5, causing the piston plate 8 to move downward. The movement of the piston plate 8 causes the spring 7 to contract. At the same time, the piston rod 9 drives the air inlet valve plate 10 to move downward and disengage from the top of the valve chamber 2, allowing air to enter the air chamber 4. The air can flow inside the intake valve body 1, and at the same time, the air compressor draws in air, allowing air to be drawn into the intake pipe 11 through the intake shroud 14, filter element 18, and protective core 15. Under normal conditions, the weight of the hollow rod 20, hollow cylinder 21, and blowout preventer plate 22 keeps the blowout preventer plate 22 detached from the bottom of the inner extension ring 12, thus not affecting the airflow during intake. The incoming air enters the air compressor head through the valve chamber 2 and intake channel 3. When the filter element 18 needs cleaning, air enters the fixed air pipe 23, causing the air to flow into the nozzle 24 and the fixed pipe 25. The air blown out by the nozzle 24... The impeller 31 is driven to rotate, which in turn drives the rotating tube 26 to rotate. The rotation of the rotating tube 26, through the fixed horizontal tube 28, drives the fixed vertical tube 29 to rotate. Simultaneously, air flowing into the fixed tube 25 enters the rotating tube 26, passes through the fixed horizontal tube 28, and enters the fixed vertical tube 29. This air is then blown out through the jet nozzle 30 towards the outside of the filter element 18, automatically cleaning the dust trapped on the outside of the filter element 18. The cleaned dust is automatically discharged through the dust discharge groove at the support ring 13. When the air compressor stops working, it stops pressurizing the air chamber 4. The spring force of the spring 7 causes the piston plate 8 to move upwards, allowing air to enter the air chamber 4. The intake valve plate 10 seals the top of the valve chamber 2, achieving one-way flow of the medium. Since the intake valve plate 10 is frequently opened and closed with the start of the air compressor, it is easily damaged. The oil inside the air compressor flows into the intake pipe 11 through the gap between the intake valve plate 10 and the valve chamber 2. When the oil comes into contact with the hollow cylinder 21, the hollow cylinder 21 moves upward due to buoyancy. The hollow rod 20 causes the blowout preventer plate 22 to fit against the bottom of the inner extension ring 12, thereby sealing the intake pipe 11, preventing oil from spraying out and causing waste, and at the same time preventing oil from seeping into the filter element 18 and causing damage to the filter element 18.

[0039] The above are merely preferred embodiments of the present invention. Any person skilled in the art may modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention are within the scope of protection claimed by the present invention.
