Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and more specifically, to an air compressor with an intake air filter. Background Technology

[0002] The intake filtration system in air compressor equipment is one of the core components to ensure stable operation of the equipment. In industrial applications, the intake filtration device purifies the intake air through a multi-layer physical interception mechanism, effectively blocking impurities such as dust and oil mist from entering the compressor, thereby avoiding abnormal wear of precision parts and lubricating oil contamination. Modern air compressors generally use filter element structures for intake filtration.

[0003] However, when the filter screen is clogged due to increased pressure loss caused by dust accumulation, the machine must be stopped to disassemble and clean the filter screen. This process not only interrupts the continuity of production and affects processing efficiency, but also requires hourly maintenance under high dust conditions. Therefore, developing an air intake filter structure that supports dynamic cleaning without stopping the machine has become a key direction to break through the bottleneck of continuous operation of air compressors.

[0004] In view of this, we propose an air compressor with intake filtration. Utility Model Content

[0005] Technical problems to be solved The purpose of this invention is to provide an air compressor with intake air filtration to solve the problem mentioned in the background art that traditional air compressors with intake air filtration are not convenient for cleaning the filter screen without stopping the machine. Technical solution

[0006] An air compressor with intake filtration includes an air compressor body and an intake pipe connected to the air compressor body for intake compression. A filter chamber is fixedly connected to the intake pipe. A sealing cover is rotatably connected to the end of the filter chamber away from the intake pipe. An intake pump is fixedly connected to the sealing cover. A filter screen is fixedly connected inside the filter chamber. A cleaning brush is fixedly connected to the sealing cover. A first filter cover is fixedly connected to the sealing cover. A second filter cover is fixedly connected to the filter chamber. A rotating rod is fixedly connected to the first filter cover, penetrating the second filter cover. The rotating rod is used to drive the cleaning brush to rotate when rotated to clean the filter screen.

[0007] Preferably, the first filter cover and the second filter cover are sequentially fitted onto the outside of the air pump. Both the first filter cover and the second filter cover have multiple filter holes. The spacing between the filter holes is the same as the width of the filter holes, so that the first filter cover can be rotated to cooperate with the second filter cover to block each other's filter holes.

[0008] Preferably, a rotating ring with a T-shaped cross-section is fixedly connected to the sealing cover, and a rotating groove adapted to the size of the rotating ring is provided on the filter chamber.

[0009] Preferably, two connecting rods are fixedly connected to the sealing cover, and the two connecting rods are fixedly connected to the cleaning brush. The cleaning brush overlaps with the filter screen, so that when the rotating rod rotates, it can drive the cleaning brush to clean the filter screen.

[0010] Preferably, an elastic telescopic rod is fixedly connected to the rotating rod, and a limiting rod is elastically connected to the elastic telescopic rod via a spring. The second filter cover has an annular movable groove. When the limiting rod is located in the movable groove, the first filter cover can rotate relative to the second filter cover to clean the filter screen.

[0011] Preferably, the top of the second filter cover is provided with a first limiting groove, the first limiting groove being adapted to the size of the limiting rod. When the limiting rod is located in the first limiting groove, the filter holes of the first filter cover and the second filter cover overlap, so that when the air pump is working, the two can jointly filter impurities in the gas.

[0012] Preferably, the top of the second filter cover is provided with a second limiting groove, which is adapted to the size of the limiting rod. When the limiting rod is located in the second limiting groove, the filter holes of the first filter cover and the filter holes of the second filter cover are exactly offset from each other, so that the air pump can be protected when the air pump stops.

[0013] Compared with existing technologies, the advantages of this utility model are: This invention features a unique structure with a rotating double filter cover and a linked cleaning brush. The equipment can dynamically clean the filter screen while the air pump is running continuously. Simply rotating the through-type rotating rod can drive the cleaning brush to sweep away the impurities accumulated on the surface of the filter screen. This solves the operational limitation of traditional solutions that require stopping the machine to disassemble the filter screen, and significantly improves the continuous working time and production efficiency of the air compressor in dusty environments.

[0014] The dual filter cover designed in this utility model has two working modes: when the limiting rod is locked in the first limiting groove, the double-layer filter holes completely overlap for filtration, while when the limiting rod is rotated into the second limiting groove, the staggered filter holes form a physical barrier to prevent environmental dust from entering the air pump during shutdown. This switchable protection mechanism not only ensures the filtration efficiency during operation, but also solves the risk of secondary pollution during maintenance.

[0015] The entire cleaning process of this invention is performed in a completely enclosed filter chamber. The precise fit between the T-shaped rotating ring and the rotating groove ensures that there is no risk of leakage when the sealing cover rotates. The limit mechanism controlled by the elastic telescopic rod enables visual locking of the operating status, which significantly improves the practicality and convenience of the device.

[0019] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figure 1-6 This utility model provides a technical solution: An air compressor with intake filtration includes an air compressor body 1 and an intake pipe 101 connected to the air compressor body 1 for intake compression. A filter chamber 102 is fixedly connected to the intake pipe 101. A sealing cover 121 is rotatably connected to the end of the filter chamber 102 away from the intake pipe 101. An air pump 123 is fixedly connected to the sealing cover 121. A filter screen 4 is fixedly connected inside the filter chamber 102. A cleaning brush 7 is fixedly connected to the sealing cover 121. A first filter cover 2 is fixedly connected to the sealing cover 121. A second filter cover 3 is fixedly connected to the filter chamber 102. A rotating rod is fixedly connected to the first filter cover 2, penetrating the second filter cover 3. The rotating rod is used to drive the cleaning brush 7 to rotate and clean the filter screen 4 when rotated. With this configuration, the dual functions of cleaning the filter screen 4 and adjusting the filtration accuracy can be achieved simultaneously through a single operation of rotating the sealing cover 121, solving the problem of low maintenance efficiency caused by the need for step-by-step disassembly and cleaning of traditional air compressors.

[0022] Secondly, the first filter cover 2 and the second filter cover 3 are sequentially fitted onto the outside of the air pump 123. Both the first filter cover 2 and the second filter cover 3 have multiple filter holes. The spacing between the filter holes is the same as the width of the filter holes, so that the first filter cover 2 can be rotated to cooperate with the second filter cover 3 to block each other's filter holes. This setting enables precise control of the filter hole area. That is to say, when the filter holes of the two covers are completely overlapped, the maximum flow rate is reached. When rotated and misaligned, physical shielding is formed and the protective mode is entered, which meets the air filtration requirements under different working conditions.

[0023] Furthermore, a rotating ring 122 with a T-shaped cross-section is fixedly connected to the sealing cover 121, and a rotating groove 103 adapted to the size of the rotating ring 122 is provided on the filter chamber 102. This arrangement, using a T-shaped rotating pair structure, ensures that the sealing cover 121 maintains axial positioning accuracy when rotating, avoids the risk of leakage caused by uneven wear of the sealing surface, and provides support for the rotation of the rotating rod 5.

[0024] Specifically, two connecting rods 6 are fixedly connected to the sealing cover 121. The two connecting rods 6 are fixedly connected to the cleaning brush 7. The cleaning brush 7 overlaps with the filter screen 4, so that when the rotating rod rotates, it can drive the cleaning brush 7 to clean the filter screen 4. This setting makes the cleaning brush 7 evenly press against the surface of the filter screen 4, eliminating cleaning dead corners caused by single-point force application and improving the cleaning effect.

[0025] In addition, an elastic telescopic rod 8 is fixedly connected to the rotating rod, and a limit rod 9 is elastically connected to the elastic telescopic rod 8 via a spring 10. The second filter cover 3 has an annular movable groove 13. When the limit rod 9 is located in the movable groove 13, the first filter cover 2 can rotate relative to the second filter cover 3 to clean the filter screen 4. This setting allows the elastic limit mechanism to provide adaptive locking during rotation, ensuring that the filter cover angle can be freely adjusted and preventing positioning failure under vibration conditions, thus ensuring the stability of the system's working state.

[0026] Specifically, the top of the second filter cover 3 is provided with a first limiting groove 11, which is adapted to the size of the limiting rod 9. When the limiting rod 9 is located in the first limiting groove 11, the filter holes of the first filter cover 2 and the second filter cover 3 overlap, so that when the air pump 123 is working, the two can filter impurities in the gas together. This station realizes the synergistic effect of double-layer filtration and ensures the air intake efficiency of the air compressor.

[0027] Furthermore, the top of the second filter cover 3 is provided with a second limiting groove 12, which is adapted to the size of the limiting rod 9. When the limiting rod 9 is located in the second limiting groove 12, the filter holes of the first filter cover 2 and the filter holes of the second filter cover 3 are exactly offset from each other, so that the suction pump 123 can be protected when it stops. This setting forms a physical isolation barrier in the locked state, effectively preventing foreign objects from entering the pump body and improving the equipment protection effect during shutdown.

[0028] Working principle: When the air compressor starts, the suction pump 123 generates negative pressure to draw external gas into the filter chamber 102. The gas first penetrates the double-layer filtration system. With the filter holes of the first filter cover 2 and the second filter cover 3 overlapping, large particles are effectively intercepted. The clean gas enters the air compressor body 1 through the intake pipe 101 for compression. At this time, the limiting rod 9 is engaged in the first limiting groove 11 at the top of the second filter cover 3 to ensure that the filter holes of the double cover are in a completely aligned state.

[0029] During operation, if cleaning of the filter screen 4 is required, the operator only needs to rotate the sealing cover 121: the T-shaped rotating ring 122 rotates smoothly along the rotating groove 103 of the filter chamber 102, driving the rotating rod to rotate synchronously. Through the symmetrically arranged connecting rods 6, the cleaning brush 7 is driven to scrape the entire surface of the filter screen 4, efficiently removing attached impurities. During this process, the limiting rod 9 on the elastic telescopic rod 8 disengages from the first limiting groove 11 and slides into the annular movable groove 13, giving the first filter cover 2 rotational freedom. When the sealing cover 121 is continuously rotated until the limiting rod 9 reaches the second limiting groove 12, the first filter cover 2 deflects. At this time, the double-cover filter holes are completely misaligned, forming a dense protective barrier, effectively preventing impurities from entering the pump body.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
