Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, specifically to an anti-clogging air compressor inlet. Background Technology

[0002] In the field of air compressor applications, the air intake filtration system is a key component for ensuring the long-term operation of the equipment. With increasingly stringent dust control requirements in industrial environments, high-efficiency anti-clogging air intake structures have become a focus of technological research and development. Current mainstream solutions mostly adopt multi-stage filtration designs, intercepting particulate matter by setting metal screens or fiber filter layers in the air intake channel. To address the problem of dust accumulation on the filter screens, some advanced equipment has introduced physical cleaning methods such as mechanical vibration and airflow backflushing to maintain unobstructed air intake.

[0003] In the existing technology, a typical anti-clogging air inlet uses a filter module with vibration function. This solution installs a liftable filter screen frame in a square main pipe. The screen frame is periodically lifted by a bottom cam mechanism, and the vibration generated by gravity falling back is used to achieve dust removal. Its chip discharge channel adopts a normally open dust collection trough design, which is directly connected to an external collection container.

[0004] The above-mentioned solution has significant drawbacks in practical applications. First, the vibration force generated by gravity falling back is limited and it is difficult to effectively remove tightly attached particles. Second, the open structure of the dust collection tank causes the high-speed airflow to easily pick up the collected debris when the compressor restarts, resulting in secondary pollution of the filter screen. Third, the dust removal action and the chip removal function lack linkage control, and the chip removal channel cannot be opened simultaneously during vibration dust removal, causing some shaken-off particles to remain in the airflow area. These problems together restrict the continuous cleaning efficiency of the air intake system.

[0005] Based on this, the present invention designs an anti-clogging air compressor inlet to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an anti-clogging air compressor inlet.

[0007] To achieve the above objectives, this utility model provides the following technical solution: An anti-clogging air compressor inlet includes a square tube and two sets of symmetrically arranged intake pipes, with the two sets of intake pipes fixedly connected to both sides of the square tube. It also includes a lifting mechanism, an energy storage mechanism, and a chip removal mechanism. Fixing strips are fixedly connected to the upper and lower sides of the inside of the square tube. A mounting plate is slidably connected between the two sets of fixing strips. A groove is formed on the outside of the mounting plate, and a filter screen is fixedly installed inside the groove. A lifting block, which is a curved frustum structure, is fixedly connected to the lower side of the mounting plate and is slidably connected to the bottom of the square tube. The lifting mechanism is installed at the bottom of the square tube. An installation groove is formed on the top inner side of the square tube, and the energy storage mechanism is installed between the installation groove and the mounting plate. A collection groove and a discharge hole are formed at the bottom of the square tube. A collection box is fixedly connected to the bottom of the discharge hole. A sliding groove is formed on the inner side of the bottom of the square tube, intersecting with the discharge hole. The chip removal mechanism is installed inside the sliding groove.

[0008] Furthermore, a mesh is fixedly connected to the inner side of both sets of air intake pipes, and one set of air intake pipes has threads on the outside.

[0009] Furthermore, the lifting mechanism includes a mounting base, a drive motor, a rotating shaft, a rotating rod, and a protective cover. The mounting base is fixedly connected to the bottom of the square tube, and the protective cover is fixedly connected to the lower side of the mounting base.

[0010] Furthermore, the drive motor is fixedly connected inside the protective cover, the rotating shaft is fixedly connected outside the output shaft of the drive motor, and the rotating shaft is rotatably connected to the inner side of the mounting base. The rotating rod is fixedly connected outside the rotating shaft, and the rotating rod is matched with the lifting block.

[0011] Furthermore, the energy storage mechanism includes a fixed plate and a compression spring. The fixed plate is fixedly connected to the top of the mounting plate and slidably connected to the inner side of the fixing strip. The compression spring is fixedly connected between the fixed plate and the mounting groove.

[0012] Furthermore, the collecting groove is located at the bottom inner side of the square tube, and the discharge hole is located at the bottom outer side of the square tube. The collecting groove and the discharge hole are connected. A guide plate is fixedly connected to the outside of the fixing strip at the bottom, and the bottom end of the guide plate matches the collecting groove.

[0013] Furthermore, the chip removal mechanism includes a sliding plate, a positioning plate, a tension spring, and a pull rope. The sliding plate is slidably connected to the inner side of the chute. A through hole is provided on the outer side of the sliding plate, and the through hole matches the discharge hole.

One end of the pull rope is fixedly connected to the other side of the sliding plate, and the other end of the pull rope is fixedly connected to the outside of the lifting block.

[0014] Furthermore, the positioning plate is fixedly connected to the inside of the slide groove, and there are two sets of positioning plates arranged horizontally. When the slide plate abuts against the positioning plate near the lifting block, the through hole and the discharge hole are aligned. When the slide plate abuts against the other set of positioning plates, the through hole and the discharge hole are misaligned.

[0015] Compared with the prior art, the advantages of this utility model are as follows: 1. The air inlet of the anti-clogging air compressor periodically lifts the lifting block by driving the rotating rod with a motor. The strong impact vibration generated by the spring energy storage and gravity falling can efficiently remove stubborn particles attached to the filter screen. Compared with the traditional solution that relies solely on gravity vibration, the unclogging effect is significantly improved, ensuring that the compressor maintains a stable air intake efficiency for a long time. 2. The air compressor inlet of this anti-clogging system opens and closes the discharge hole by pulling the rope and controlling the slide plate during the lifting block's raising and lowering process. This achieves automatic synchronization between the chip discharge channel and the filter screen vibration cleaning, which can not only discharge debris in time when clearing blockages, but also close the channel when the compressor is running, completely avoiding secondary pollution and improving the overall cleaning reliability.

[0020] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-8An anti-clogging air compressor inlet includes a square tube 2 and two sets of symmetrically arranged intake pipes 1. The square tube 2 serves as the main frame of the entire intake system, with its internal cavity forming the main airflow channel. The two sets of intake pipes 1 are fixedly connected to both sides of the square tube 2, serving as the compressor's intake interface. The system also includes a lifting mechanism, an energy storage mechanism, and a chip removal mechanism. Fixing strips 4 are fixedly connected to the upper and lower sides of the inside of the square tube 2, acting as guide rails to ensure stable operation of moving parts. A mounting plate 5 is slidably connected between the two sets of fixing strips 4, serving as a support platform for the filter assembly. A groove is formed on the outside of the mounting plate 5, and a filter screen 6 is fixedly installed within the groove. The filter screen 6 serves as the core filter element for intercepting solid particles in the air. A lifting block 7, which is a curved frustum structure, is fixedly connected to the lower side of the mounting plate 5. The lifting block 7 is designed to facilitate interaction with the lifting mechanism. The lifting block 7 is slidably connected to the bottom of the square tube 2. The lifting mechanism is installed at the bottom of the square tube 2 and is responsible for providing periodic impact power. An installation groove 13 is provided on the top inner side of the square tube 2. The installation groove 13 provides installation space for the energy storage mechanism. The energy storage mechanism is installed between the installation groove 13 and the installation plate 5 and is used to store and release mechanical energy. A collection groove 16 and a discharge hole 17 are provided at the bottom of the square tube 2. The collection groove 16 is used to temporarily store the removed impurities. A collection box 19 is fixedly connected to the bottom of the discharge hole 17. The collection box 19 serves as the final impurity container. A sliding groove 18 is provided on the inner bottom of the square tube 2. The sliding groove 18 provides a movement track for the chip removal mechanism. The sliding groove 18 intersects with the discharge hole 17. The chip removal mechanism is installed on the inner side of the sliding groove 18 and is used to control the opening and closing of the chip removal channel.

[0021] Both sets of intake pipes 1 are fixedly connected to the inner side of a mesh 3. The mesh 3 serves as a primary filter layer to intercept larger particles. One set of intake pipes 1 has threads on the outside, and the thread design facilitates connection with the compressor intake pipe.

[0022] The lifting mechanism includes a mounting base 8, a drive motor 9, a rotating shaft 10, a rotating rod 11, and a protective cover 12. The mounting base 8 is fixedly connected to the bottom of the square tube 2, serving as the mounting base for the entire lifting mechanism. The protective cover 12 is fixedly connected to the lower side of the mounting base 8 to protect the internal mechanical components.

[0023] The drive motor 9 is fixedly connected inside the protective cover 12 to provide rotational motion as a power source. The rotating shaft 10 is fixedly connected to the outside of the output shaft of the drive motor 9 to transmit rotational power. The rotating shaft 10 is rotatably connected to the inside of the mounting base 8 to ensure rotational stability. The rotating rod 11 is fixedly connected to the outside of the rotating shaft 10 and acts as a direct-acting component to cooperate with the lifting block 7. The rotating rod 11 and the lifting block 7 are matched to form an effective mechanical transmission relationship. The rotating rod 11 is a cylindrical structure, and when it contacts the inclined surface of the lifting block 7 to drive the lifting block 7 to rise, it can greatly reduce friction.

[0024] The energy storage mechanism includes a fixed plate 14 and a compression spring 15. The fixed plate 14 is fixedly connected to the top of the mounting plate 5 and serves as the force-bearing platform for the compression spring 15. The fixed plate 14 is slidably connected to the inner side of the fixed strip 4 to ensure vertical movement accuracy. The compression spring 15 is fixedly connected between the fixed plate 14 and the mounting groove 13 for storing and releasing impact energy.

[0025] The collecting trough 16 is located at the bottom inner side of the square tube 2 as a temporary storage area for impurities. The discharge hole 17 is located at the bottom outer side of the square tube 2 as a discharge channel for impurities. The collecting trough 16 and the discharge hole 17 are connected to form a complete chip removal path. A guide plate 25 is fixedly connected to the outside of the fixing strip 4 at the bottom. The guide plate 25 is used to guide impurities into the collecting trough 16, and the bottom end of the guide plate 25 matches the collecting trough 16 to ensure smooth transfer of impurities.

[0026] The chip removal mechanism includes a slide plate 20, a positioning plate 22, a tension spring 23, and a pull rope 24. The slide plate 20 is slidably connected to the inner side of the slide groove 18 and serves as the switch control element for the chip removal channel. A through hole 21 is provided on the outside of the slide plate 20. The through hole 21 and the discharge hole 17 cooperate to form a controllable channel, and the through hole 21 and the discharge hole 17 are matched to ensure the accuracy of the channel opening and closing. One end of the tension spring 23 is fixedly connected to the inside of the slide groove 18 to provide a reset elastic force, and the other end of the tension spring 23 is fixedly connected to one side of the slide plate 20. One end of the pull rope 24 is fixedly connected to the other side of the slide plate 20 as a linkage control element, and the other end of the pull rope 24 is fixedly connected to the outside of the lifting block 7 to achieve synchronous movement.

[0027] The positioning plate 22 is fixedly connected to the inside of the slide groove 18 as a limiting reference for the movement of the slide plate 20. There are two sets of positioning plates 22 arranged horizontally to ensure the precise positioning of the slide plate 20. When the slide plate 20 abuts against the positioning plate 22 on the side near the lifting block 7, the through hole 21 and the discharge hole 17 are aligned to form a chip removal channel. When the slide plate 20 abuts against another set of positioning plates 22, the through hole 21 and the discharge hole 17 are misaligned to close the channel.

[0028] In this embodiment, when the air compressor is running and intakes air, the air is first filtered through the mesh 3 inside the intake pipe 1 to block larger impurities. Then, the air enters the square pipe 2 and flows through the filter screen 6 on the mounting plate 5. The filter screen 6 blocks fine dust, gravel and other particles on the outside to ensure that clean air enters the compressor. As the usage time increases, particles will gradually adhere to or clog the filter screen 6, affecting the intake efficiency.

[0029] To avoid clogging, when the air compressor stops intake, the drive motor 9 is started to drive the rotating shaft 10 and the rotating rod 11 on it to rotate. When the rotating rod 11 contacts the inclined surface of the lifting block 7, it generates an upward thrust, forcing the lifting block 7 and the mounting plate 5 fixed to it to overcome the resistance of gravity and the compression spring 15 and slide upward along the upper and lower fixing bars 4, thereby compressing the compression spring 15. When the rotating rod 11 sweeps past the bottom end of the lifting block 7 and disengages, the mounting plate 5, under the combined action of its own gravity and the elastic force stored in the compression spring 15, instantly accelerates downward. The fixing plate 14 at the top of the mounting plate violently hits the fixing bar 4 above, generating a strong vibration. This vibration is transmitted to the filter screen 6, effectively shaking off the particles attached to its surface or clogging the mesh. By continuously running the drive motor 9 to drive the rotating rod 11 to periodically lift and release the lifting block 7, continuous and efficient self-cleaning of the filter screen 6 can be achieved.

[0030] Furthermore, during the upward movement of the lifting block 7 by the rotating rod 11, the sliding plate 20 can be pulled within the chute 18 by the pull rope 24 on one side of the lifting block 7. Simultaneously, the tension spring 23 is stretched. When the rotating rod 11 sweeps past the bottom end of the lifting block 7 and disengages, the sliding plate 20 is pulled against the positioning plate 22 on that side. The through hole 21 on the plate 22 aligns perfectly with the discharge hole 17 at the bottom of the square tube 2. At this point, the dislodged debris and particles, under the influence of gravity, are guided by the guide plate 25 into the collection trough 16, passing through the aligned through hole 21 and discharge hole 17, and finally falling into the collection trough below. The debris is temporarily stored in box 19. When the drive motor 9 stops working, the lifting block 7 returns to its original position and falls under the action of gravity. The pull rope 24 then loosens, and the stretched spring 23 contracts, pulling the slide plate 20 to slide in the opposite direction until it touches the positioning plate 22 on the other side. At this position, the through hole 21 on the slide plate 20 is completely misaligned with the discharge hole 17. The solid part of the slide plate 20 re-seals the discharge hole 17. This design ensures that when the air compressor restarts and the airflow flows through the square tube 2, the debris particles in the collection box 19 will not be blown up by the airflow and re-adsorbed onto the filter screen 6, effectively maintaining the cleaning effect.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
