[0002] In media transport systems, riser distributors are key devices for achieving media diversion control and are widely used in chemical, water conservancy, and energy fields. Their core function is to distribute the media in a single pipeline to multiple branches through the coordinated operation of main and auxiliary valves to meet different transport requirements.

[0003] Traditional pneumatic riser diverters typically consist of a housing, valve assemblies, etc. They achieve media diversion and cut-off by pneumatically controlling the opening and closing of valves, which basically meets the needs of conventional media transportation and diversion scenarios.

[0004] However, the medium often contains solid particles and impurities during transportation. If it enters the diversion system directly, it will not only affect the diversion accuracy, but may also cause wear and blockage of valve components, leading to frequent equipment failures and increased maintenance costs. Although some diverters have added filter structures, the filter pores of the filter components are easily blocked by the accumulation of impurities, and there is a lack of convenient cleaning mechanisms. Frequent disassembly of the equipment is required for cleaning, which seriously affects the continuous operation efficiency of the system. Therefore, a pneumatic riser diverter is proposed to solve the above problems. Summary of the Invention

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a pneumatic riser diverter, comprising a diverter housing 1. The side wall of the diverter housing 1 has an internal threaded groove, allowing a main pneumatic valve switch to be installed on its surface. Two sets of internal threaded grooves are provided on its upper surface, allowing for the installation of a secondary pneumatic valve switch for diverting flow. A baffle plate 4 is detachably installed on the inner wall of the bottom end of the diverter housing 1 via a locking screw 5. An installation groove is provided at the bottom end of the diverter housing 1, with the outer wall of the baffle plate 4 contacting the inner wall of the installation groove. An empty groove is provided at the bottom end of the diverter housing 1, allowing the filter plate 22 to intercept the flow. The impurities will fall into the baffle plate 4 installed in the mounting groove at the bottom of the distributor housing 1. The side wall at the bottom of the distributor housing 1 has an internal thread groove. The locking screw 5 is threaded to the side wall at the bottom of the distributor housing 1. The locking screw 5 passes through and is threaded to the inner wall at the bottom of the baffle plate 4. By rotating the locking screw 5, the threaded contact with the inner wall at the bottom of the distributor housing 1 is canceled, so that the baffle plate 4 can be pulled out as a whole, so as to facilitate the centralized treatment of the impurities collected inside. The inner side wall of the distributor housing 1 is provided with a filter cleaning component 2 and two sets of sealing rings 3.

[0034] Reference Figure 2 and Figure 4 - Figure 5 The filter cleaning component 2 includes a rotating ring 21. An annular groove is provided at the center of the distributor housing 1. The rotating ring 21 is rotatably connected to the inner wall of the annular groove of the distributor housing 1. The outer sidewall of the sealing ring 3 contacts the two sidewalls of the rotating ring 21. Connecting blocks are provided at the bottom and both sides of the annular groove of the distributor housing 1. The annular groove can support the rotating ring 21, so that it can only rotate circumferentially inside the distributor housing 1. Through contact with the sealing ring 3, the sealing effect between the rotating ring 21 and the distributor housing 1 is guaranteed.

[0035] Reference Figure 4 and Figure 5A connecting seat 25 is fixedly connected to the inner side wall of the rotating ring 21, and a filter plate 22 is fixedly connected to the inner side wall of the distributor housing 1. The filter plate 22 filters impurities such as liquid and air entering through the main inlet on the left side of the distributor housing 1. A T-shaped block 26 is fixedly connected to the front surface of the connecting seat 25. When the rotating ring 21 rotates, it drives the connecting seat 25 to rotate synchronously, and the connecting seat 25, in turn, drives the T-shaped block 26 to rotate synchronously. A drain ball 28 is elastically connected to the inner side wall of the T-shaped block 26 via a return spring 27. One end of the return spring 27 is fixedly connected to the inner side wall of the T-shaped block 26, and the other end is fixedly connected to the rear end of the drain ball 28. The function of the positioning spring 27 is to automatically reset the position of the spherical surface at the front end of the unblocking ball 28 after it has been squeezed and moved by the inner side of the filter hole of the filter plate 22. The surface of the filter plate 22 has filter holes. The outer wall of the unblocking ball 28 is in contact with the inner wall of the filter hole of the filter plate 22. The contact between the two can unblock any impurities that may enter the filter hole of the filter plate 22, and prevent them from becoming blocked, thereby affecting the flow of the medium. The unblocking ball 28 is slidably connected to the inner side wall of the T-shaped block 26. The upper surface of the rotating ring 21 is fixedly connected to the lever 23. The surface of the lever 23 has an anti-slip groove. The lever 23 can be easily moved to drive the rotating ring 21 to rotate synchronously. The inner side wall of the lever 23 is provided with a sealing adjustment component 24.

[0036] Reference Figure 4 - Figure 5 The sealing adjustment assembly 24 includes a threaded rod 241. A movable plate 242 is rotatably connected to the bottom end of the outer wall of the threaded rod 241. The threaded rod 241 passes through and is threadedly connected to the inner wall of the top end of the lever block 23. An internal threaded groove is provided on the inner wall of the top end of the lever block 23, allowing the threaded rod 241 to move up and down threadedly on the inner wall of the top end of the lever block 23. At the same time, when the threaded rod 241 rotates, it will drive the movable plate 242 to descend synchronously. The movable plate 242 is slidably connected to the inner side wall of the lever block 23. Two sets of hinge rods 243 are hinged to the bottom end of the movable plate 242. The two sets of hinge rods 243 are far away from the movable plate 23. One end of the moving plate 242 is hinged to a contact block 244. When the moving plate 242 moves up and down in the thread, it pushes the corresponding contact block 244 to move outward or inward on the inner side of the rotating ring 21 through two sets of inclined hinge rods 243. The contact block 244 passes through and is slidably connected to the inner side wall of the rotating ring 21. The outer wall of the contact block 244 is in contact with the outer surface of the sealing ring 3. The contact between the two can make a squeezing contact with the sealing ring 3 through the contact of the contact block 244, thereby increasing the sealing performance between the rotating ring 21 and the distributor housing 1.

[0037] Working principle: During the media transportation process, the main pneumatic valve switch is installed in the internal thread groove on the side wall of the distributor housing 1 to control the flow of the main medium; two sets of auxiliary pneumatic valve switches are installed in the internal thread groove on the upper surface of the distributor housing 1 to realize the diversion of the medium. When the medium enters from the main inlet on the left side of the distributor housing 1, it first passes through the filter plate 22 in the filter cleaning assembly 2. The filter plate 22 will filter and intercept impurities in the medium. The filtered medium is diverted through the main and auxiliary pneumatic valve switches.

[0038] The filter cleaning assembly 2 can also perform cleaning during the filtration process. Rotating the lever 23, which is fixedly connected to the upper surface of the rotating ring 21, causes the rotating ring 21 to rotate circumferentially within the annular groove of the distributor housing 1. When the rotating ring 21 rotates, the connecting seat 25 on its inner sidewall rotates synchronously, thereby causing the T-shaped block 26 to rotate. The unclogging ball 28, elastically connected to the inner side of the T-shaped block 26 via a return spring 27, contacts the inner wall of the filter holes in the filter plate 22 as the T-shaped block 26 rotates. During this contact, the unclogging ball 28 is compressed by the inner wall of the filter holes, compressing the return spring 27. When it rotates to the edge of the filter holes, the return spring 27 returns to its original position. Pushing the unblocking ball 28 unblocks the filter holes, preventing blockage and ensuring smooth media flow. Simultaneously, impurities intercepted by the filter plate 22 fall into the baffle plate 4 in the mounting groove at the bottom of the distributor housing 1. When these impurities need to be processed, loosen the locking screw 5 to remove it from the threaded contact with the bottom side wall of the distributor housing 1. Then, the baffle plate 4 can be pulled out of the mounting groove at the bottom of the distributor housing 1 to collect the impurities. After processing, reinstall the baffle plate 4 in its original position and tighten the locking screw 5 so that it passes through and is threadedly connected to the inner wall at the bottom of the baffle plate 4 and the bottom side wall of the distributor housing 1, thus fixing the baffle plate 4.

[0039] Meanwhile, to ensure the sealing effect between the rotating ring 21 and the distributor housing 1, it can be adjusted by the sealing adjustment component 24. Rotating the threaded rod 241 will cause the moving plate 242 to slide down the inner side wall of the toggle block 23 due to the threaded connection between the threaded rod 241 and the inner wall of the toggle block 23. When the moving plate 242 descends, it pushes the contact block 244 to slide outward on the inner side wall of the rotating ring 21 through the two sets of hinge rods 243, so that the outer wall of the contact block 244 is in close contact with the outer surface of the sealing ring 3, increasing the squeezing force between the two, thereby enhancing the connection sealing between the rotating ring 21 and the distributor housing 1. The two sets of sealing rings 3 also further ensure the overall sealing performance.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
