Description

Technical Field

[0001] This utility model relates to the field of pneumatic regulating valve technology, specifically a pneumatic regulating valve with a filter structure. Background Technology

[0002] A pneumatic control valve is an industrial control device that uses compressed air as a power source and a pneumatic actuator to drive the valve core to move, thereby automatically regulating the process parameters such as flow rate, pressure, temperature or liquid level of fluid media (such as gas, liquid, steam, etc.). Existing pneumatic control valves usually have a filter structure to avoid blockage inside the valve body.

[0003] In the existing technology, after a long period of use, the filter pores of the filter structure are easily clogged by impurities, which is not only difficult to clean, but also affects the filtration effect of the filter structure. At the same time, the impurities intercepted by the filter are not easy to clean, making it difficult to achieve centralized treatment of impurities, which brings many inconveniences to the normal use and maintenance of pneumatic control valves.

[0004] Therefore, a pneumatic regulating valve with a filter structure is needed to solve the problem that the filter structure is easily clogged by impurities after long-term use in the existing technology, and the impurities intercepted by the filter are not easy to clean. Utility Model Content

[0005] The purpose of this invention is to provide a pneumatic regulating valve with a filter structure to solve the problem in the prior art that the filter structure is easily clogged by impurities after long-term use, and the impurities filtered and intercepted are not easy to clean.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pneumatic regulating valve with a filtering structure, comprising a valve body, a filter box installed on the valve body for filtering, an installation groove opened inside the filter box, a fixing block fixedly connected in the installation groove, and a filter plate installed inside the filter box for filtering. The installation groove is provided with a striking mechanism that causes the filter plate to vibrate, and the filter box is provided with a cleaning component for cleaning the filter plate.

[0007] The striking mechanism includes a rotating shaft rotatably connected in the mounting groove, a cam fixedly connected to the outer surface of the rotating shaft, a force-bearing block movably disposed in the mounting groove, a rubber rod fixedly connected to the right side of the force-bearing block for striking the filter plate, a fixing plate slidably sleeved on the outer surface of the rubber rod, a spring installed on the outer surface of the rubber rod for realizing the reset movement of the rubber rod, and a limiting ring fastened to the outer surface of the rubber rod for limiting the position of the rubber rod.

[0008] It should be noted in the solution that the cleaning component includes a support frame fixedly connected inside the filter box, a transmission rod rotatably connected to the left side of the support frame, and a brush plate fastened to the outer surface of the transmission rod for cleaning the filter plate.

[0009] It is worth noting that a support rod is fixedly connected inside the filter box, a protective shell is fixedly connected to the support rod, a blade for driving the transmission rod to rotate is fixedly connected to the transmission rod, a driving bevel gear for transmission is fastened to the outer surface of the transmission rod, and a driven bevel gear that meshes with the driving bevel gear is fixedly connected to the bottom of the rotating shaft.

[0010] Furthermore, it should be noted that the bottom surface of the filter box is provided with a through hole for impurities to pass through, and a collection box for collecting impurities is fixedly connected to the bottom surface of the filter box. The front end of the collection box is provided with an openable and closable sealing door for processing internal impurities.

[0011] In a preferred embodiment, the fixing block is fixedly connected to the filter plate, and the fixing plate is fixedly connected to the inside of the mounting groove.

[0012] In a preferred embodiment, the two sides of the spring are fixedly connected to the outer wall of one side of the force-bearing block and the outer wall of one side of the fixing plate, respectively, and the bristles on the brush plate are in contact with the outer wall of the left side of the filter plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The rotating shaft drives the cam to repeatedly push the force block, which in turn drives the rubber rod to strike the fixed block, knocking out impurities in the filter holes. This effectively avoids the problem of the filter structure being easily clogged by impurities after long-term use.

[0015] 2. The brush plate is driven to rotate by the transmission rod. The brush plate cleans the filter plate. The impurities knocked out and the cleaned impurities fall into the collection box together.

[0021] 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.

[0022] Example: Figures 1-4 As shown, this utility model provides a technical solution, including a valve body 1, a filter box 2 installed on the valve body 1 for realizing the filtration function, an installation groove 3 opened inside the filter box 2, a fixing block 4 fixedly connected in the installation groove 3, and a filter plate 5 installed in the filter box 2 for filtration. The installation groove 3 is provided with a striking mechanism 6 that causes the filter plate 5 to vibrate, and the filter box 2 is provided with a cleaning component 7 for cleaning the filter plate 5.

[0023] The striking mechanism 6 includes a rotating shaft 61 rotatably connected in the mounting groove 3, a cam 62 fixedly connected to the outer surface of the rotating shaft 61, a force-receiving block 63 movably disposed in the mounting groove 3, a rubber rod 64 fixedly connected to the right side of the force-receiving block 63 for striking the filter plate 5, a fixing plate 65 slidably sleeved on the outer surface of the rubber rod 64, a spring 66 installed on the outer surface of the rubber rod 64 for realizing the reset movement of the rubber rod 64, and a limiting ring 67 fastened to the outer surface of the rubber rod 64 for limiting the movement of the rubber rod 64.

[0024] Specifically, when the rotating shaft 61 rotates, it drives the cam 62 to rotate. The cam 62 pushes the force block 63, and the force block 63 pushes the rubber rod 64 to strike the filter plate 5, shaking out the impurities inside the filter plate 5. Under the elastic action of the spring 66, the rubber rod 64 is reset in conjunction with the limiting ring 67. As the rotating shaft 61 continues to rotate, the rubber rod 64 reciprocates and strikes the filter plate 5. In conjunction with the cleaning component 7, the surface of the filter plate 5 is cleaned, and the shaken-out impurities are swept off the filter plate 5.

[0025] Further as Figure 2 and Figure 4 As shown, it is worth noting that the cleaning assembly 7 includes a support frame 71 fixedly connected inside the filter box 2, a transmission rod 72 rotatably connected to the left side of the support frame 71, and a brush plate 73 fastened to the outer surface of the transmission rod 72 for cleaning the filter plate 5.

[0026] Specifically, when the transmission rod 72 rotates, it drives the brush plate 73 to rotate. During the rotation, the brush plate 73 cleans the filter plate 5 to prevent the filter plate 5 from being blocked by impurities in the medium.

[0027] Further as Figure 2 and Figure 4 As shown, it is worth noting that a support rod 8 is fixedly connected inside the filter box 2, a protective shell 9 is fixedly connected to the support rod 8, a blade 10 for driving the transmission rod 72 is fixedly connected to the transmission rod 72, a drive bevel gear 11 for transmission is fastened to the outer surface of the transmission rod 72, and a driven bevel gear 12 that meshes with the drive bevel gear 11 is fixedly connected to the bottom of the rotating shaft 61.

[0028] Specifically, the protective shell 9 protects the driving bevel gear 11 and the driven bevel gear 12. The blade 10 fixed on the transmission rod 72 rotates after contacting the medium, thereby driving the transmission rod 72 to rotate. When the transmission rod 72 rotates, it drives the driving bevel gear 11 to rotate, which in turn drives the rotating shaft 61 to rotate through the driven bevel gear 12. This causes the rotating shaft 61 and the transmission rod 72 to rotate simultaneously, thereby enabling the striking mechanism 6 to cooperate with the cleaning assembly 7.

[0029] Further as Figure 1 and Figure 2 As shown, it is worth noting that the bottom surface of the filter box 2 is provided with a through hole 13 for impurities to pass through, and a collection box 14 for collecting impurities is fixedly connected to the bottom surface of the filter box 2. The front end of the collection box 14 is provided with an openable and closable sealing door 15 for processing internal impurities.

[0030] Specifically, the brush plate 73 collects the impurities removed from the filter plate 5 through the through hole 13 into the collection box 14. After the sealing door 15 is opened, it is convenient for staff to clean the impurities collected inside the collection box 14.

[0031] Further as Figure 2 and Figure 3 As shown, it is worth noting that the fixing block 4 is fixedly connected to the filter plate 5, and the fixing plate 65 is fixedly connected to the inside of the mounting groove 3.

[0032] Specifically, the fixing block 4 is fixedly connected to the filter plate 5. When the rubber rod 64 strikes the fixing block 4, the filter plate 5 vibrates, shaking out the impurities in the filter holes on the filter plate 5. The fixing plate 65 is fixedly connected to the inside of the mounting groove 3, supporting the rubber rod 64 and improving the stability of the rubber rod 64 when it moves.

[0033] Further as Figure 2 and Figure 3 As shown, it is worth noting that the two sides of the spring 66 are fixedly connected to the outer wall of one side of the force-bearing block 63 and the outer wall of one side of the fixing plate 65, respectively, and the bristles on the brush plate 73 are in contact with the outer wall of the left side of the filter plate 5.

[0034] Specifically, the two sides of the spring 66 are fixedly connected to the outer wall of one side of the force-bearing block 63 and the outer wall of one side of the fixing plate 65, respectively. Under the elastic action of the spring 66, the moved rubber rod 64 has a resettable property. The bristles on the brush plate 73 are in contact with the outer wall of the left side of the filter plate 5. When the transmission rod 72 drives the brush plate 73 to rotate, the bristles on the brush plate 73 clean the filter plate 5.

[0035] In summary: When this pneumatic regulating valve is in use, the medium enters the filter box 2 and is filtered by the filter plate 5. At the same time, the medium pushes the blade 10, which rotates and drives the transmission rod 72 to rotate. The transmission rod 72 drives the driving bevel gear 11 to rotate. Under meshing action, the driving bevel gear 11 drives the driven bevel gear 12 to rotate. The driven bevel gear 12 drives the cam 62 to rotate through the rotating shaft 61. The cam 62 repeatedly pushes the force block 63. When the force block 63 is under force, it pushes the rubber rod 64 to continuously knock the fixed block 4, causing the filter plate 5 to vibrate and knock out the impurities in the filter holes. This prevents impurities from clogging the filter plate 5 and effectively avoids the problem of the filter structure being easily clogged by impurities after long-term use.

[0036] When the transmission rod 72 rotates, it drives the brush plate 73 to clean the filter plate 5, further improving the cleaning effect of the filter plate 5. The cleaned impurities fall into the collection box 14 through the through hole 13 for collection. At the same time, the impurities shaken off the filter plate 5 also enter the collection box 14 through the through hole 13. After a period of use, the sealing door 15 is opened to clean the impurities stored in the collection box 14, completing the centralized processing of the intercepted impurities. The operation is simple and effectively avoids the problem of the impurities intercepted by the filter being difficult to clean.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
