Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary valve technology, specifically to an anti-clogging device for an adaptive diameter fast-switching rotary valve. Background Technology
[0002] A rotary valve is a common industrial valve, mainly used to control the flow of media. Its structure mainly includes a valve body, valve cover, valve core, and sealing surface. The working principle is to control the flow of media by rotating the valve core. Rotary valves are characterized by their tight shut-off, good flow performance, good corrosion resistance, and stable operation.
[0003] Rotary valves are widely used in many industrial production processes to control the flow of fluids (such as gases, liquids, or mixtures containing solid particles). However, when traditional rotary valves handle fluids containing impurities, particles, or fibers, the valve inlet is easily blocked. This not only reduces the flow efficiency of the fluid but may also lead to the failure of the entire production system, increasing maintenance costs and downtime, thus making them impractical. Therefore, it is necessary to design an adaptive diameter quick-switching rotary valve anti-blocking device to address the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an anti-clogging device for an adaptive caliber quick-switching rotary valve. This solves the problem that when traditional rotary valves handle fluids containing impurities, particles, or fibers, the inlet of the rotary valve is easily blocked. This not only reduces the flow efficiency of the fluid but may also lead to the failure of the entire production system, increasing maintenance costs and downtime.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0014] This utility model provides a technical solution for an anti-clogging device for an adaptive caliber fast-switching rotary valve: Please see Figures 1-4 An anti-clogging device for an adaptive caliber quick-switching rotary valve includes a valve body 1. An anti-clogging channel 2 is fixedly installed at the inlet of the valve body 1. A connecting sleeve 3 is fixedly installed on the outer wall of the anti-clogging channel 2. A mating sleeve 4 is fixedly installed inside the connecting sleeve 3. The mating sleeve 4 has a tapered cross-section. Multiple compression bolts 5 are threadedly installed through the outer wall of the connecting sleeve 3. Each compression bolt 5 has a compression plate 7 fixedly connected to its end through a connecting mechanism. Two sliding rods 10 are slidably installed on the inner wall of the anti-clogging channel 2 through the connecting plate 9. Limiting blocks 11 are fixedly installed on the outer walls of the two connecting blocks 11. The inner walls of the two connecting blocks 11 are connected to the outer walls of the corresponding connecting plates 9 through elastic mechanisms. The ends of the two sliding rods 10 are fixedly connected to a filter plate 13. A pressing block 14 is fixedly installed on the inner wall of the filter plate 13. A pressing groove is opened on the outer wall of the pressing block 14. A rotating shaft 15 is rotatably installed inside the anti-blocking channel 2. A motor 17 connected to the rotating shaft 15 is fixedly installed on the outer wall of the anti-blocking channel 2 through a support mechanism. An eccentric wheel 18 is fixedly installed on the outer wall of the rotating shaft 15.
[0015] Furthermore, the connecting mechanism includes a connecting block 6 fixedly installed at the end of the extrusion bolt 5, and the end of the connecting block 6 is fixedly connected to the outer wall of the extrusion plate 7.
[0016] Furthermore, the elastic mechanism includes a spring 12 installed on the outer wall of the slide bar 10, with both ends of the spring 12 elastically connected to the outer wall of the connecting plate 9 and the inner wall of the limiting block 11, respectively.
[0017] Furthermore, the support mechanism includes a support plate 16 fixedly installed on the outer wall of the anti-blocking channel 2, and a motor 17 fixedly installed on the upper surface of the support plate 16.
[0018] Furthermore, each extrusion plate 7 has an arc-shaped inner wall, and each extrusion plate 7 has an anti-slip pad 8 fixedly installed on its inner wall.
[0019] The connecting sleeve 3 can be fitted onto the outer wall of the connecting pipe, and the end of the connecting pipe can be in close contact with the inner wall of the connecting sleeve 4. The tapered inner wall of the connecting sleeve 4 can be in close contact with the ends of connecting pipes of different sizes, thereby realizing the connection between the rotary valve and connecting pipes of different sizes. Then, by rotating the pressing bolt 5, the connecting block 6 drives the pressing plate 7 to move towards the connecting pipe. Since the pressing plate 7 has an arc-shaped inner wall and is equipped with an anti-slip pad 8, it can increase the friction and contact area with the outer wall of the connecting pipe. As the pressing bolt 5 is continuously screwed in, the pressing plate 7 firmly fixes the connecting pipe to the connecting sleeve 4, completing the connection operation. During the fluid transportation process, the fluid enters the anti-blocking channel 2 through the connecting pipe. At this time, the filter plate 13 plays an interception role, blocking impurities and particles in the fluid. As time goes by, when a certain amount of impurities accumulate on the filter screen 13, the motor 17 is started. The motor 17 drives the rotating shaft 15 to rotate, and the eccentric wheel 18 on the rotating shaft 15 rotates accordingly. During the rotation of the eccentric wheel 18, its eccentric part continuously squeezes the squeezing groove on the outer wall of the squeezing block 14, causing the squeezing block 14 to drive the filter screen 13 to slide back and forth along the slide rod 10. During this process, the spring 12 on the outer wall of the slide rod 10 provides a buffer for the sliding of the filter screen 13, preventing it from being damaged due to excessive force, and also provides a buffer for the eccentric part. When the squeezing action of wheel 18 disappears, the filter screen plate 13 is reset by its own elasticity, ensuring that the filter screen plate 13 can vibrate continuously and stably. Under the high-frequency vibration of the filter screen plate 13, the impurities accumulated on the filter screen plate 13 are continuously shaken off, avoiding the accumulation of impurities that cause the filter screen plate 13 to become clogged. This ensures that the fluid can continuously and smoothly pass through the anti-clogging channel 2 into the valve body 1, thereby realizing the efficient control of the fluid by the rotary valve, meeting the needs of connecting pipes of different diameters and preventing clogging in the production process, and effectively improving the operational stability and production efficiency of the entire system.
[0020] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
