Description

Technical Field

[0001] This invention relates to the field of valves, and more particularly to a high-temperature resistant valve for industrial wastewater treatment systems. Background Technology

[0002] During industrial production, a large amount of wastewater is generated. The wastewater needs to be treated before it is discharged. Industrial wastewater flows into the treatment pool through the sewage pipe. The discharge of wastewater is controlled by the material, and valves are installed on the sewage pipe.

[0003] When sewage flows in the sewage pipe, due to the difference between chemical reactions and natural temperature, some impurities will precipitate out of the sewage and form sediment. Therefore, a filter screen needs to be installed at the sewage valve to filter the sediment. The existing valve lacks the effect of treating sediment, and it needs to be removed for cleaning. Cleaning is too troublesome. At the same time, when cleaning the valve, the sewage pipe needs to be closed, which will affect the sewage discharge and is not conducive to the use of the valve. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as: lack of effective treatment for sedimentation, the need to disassemble and clean the valve, which is too troublesome, and the need to close the drain pipe when cleaning the valve, which affects the discharge and is not conducive to the use of the valve.

A transmission structure is provided on the connecting shaft.

[0007] Preferably, a sealing cover is provided at the top of the fixed housing. The sealing cover is located on the side of the filter screen away from the fixed scraper and is slidably connected to the filter screen. The sealing cover covers the top of the fixed housing. A pushing block is fixedly connected to the side wall of the sealing cover away from the filter screen. A pushing rod is fixedly connected to the bottom end of the pushing block. The pushing rod extends through the lower inner wall of the connecting tube and into the inner side of the fixed frame. An installation rod is provided on the part of the pushing rod located inside the fixed frame. A connecting rod is fixedly connected to the bottom end of the installation rod. A spiral groove is provided on the outer side of the connecting shaft. A sliding block is slidably connected to the spiral groove. A connecting ring is sleeved on the outer side of the connecting shaft and fixedly connected to the sliding block. The connecting ring and the connecting rod are fixedly connected.

[0008] Preferably, the sealing cover has a connecting groove inside, and a threaded rod is rotatably provided on the upper inner wall of the connecting groove. The threaded rod extends through the upper inner wall of the connecting groove and extends to the outside of the sealing cover. A threaded ring corresponding to each threaded rod is fixedly connected to the top of the sealing cover. Each threaded ring is threadedly connected to a threaded rod. One end of each threaded rod located inside the connecting groove is fixedly connected to a suction fan.

[0009] Preferably, the mounting rod has an adjustment groove inside, a movable plate is slidably connected inside the adjustment groove, a connecting spring is fixedly connected to the bottom end of the movable plate, the end of the connecting spring away from the movable plate is fixedly connected to the lower inner wall of the adjustment groove, and the bottom end of the push rod passes through the upper inner wall of the mounting rod and is fixedly connected to the top end of the movable plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The sediment filtered by the filter screen is scraped into the fixed housing by a fixed scraper. The sediment is then crushed by the crushing roller inside the fixed housing, which prevents it from clogging the valve and filter screen and affecting the discharge of sewage. At the same time, the crushing roller rotates by the flow of sewage without the need for a power mechanism, making it more convenient to use. Moreover, the crushing roller can also rotate on its own during the rotation process, making the crushing more thorough.

[0015] It is equipped with a sealing cover that seals the fixed housing inside the filter screen, and the sealing cover can open and close automatically. When the sealing cover is closed, the crushing roller can crush the sediment better.

[0016] During the movement of the fixed cover, the suction fan can be rotated. When the suction fan rotates, it generates a suction force, which accelerates the flow of sewage in the fixed cover and better washes the particles inside the fixed cover. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Reference Figures 1-6A high-temperature resistant valve for an industrial wastewater treatment system includes a connecting pipe 1, a regulating valve 3 rotatably connected inside the connecting pipe 1, an adjusting rod 4 fixedly connected to the top of the regulating valve 3, a fixing plate 6 fixedly connected to the lower inner wall of the connecting pipe 1, a fixing shaft 7 fixedly connected to the side wall of the fixing plate 6 away from the regulating valve 3, a filter screen 5 fixedly installed inside the connecting pipe 1, the fixing shaft 7 penetrating the filter screen 5, an impact fan 8 fixedly connected to the portion of the fixing shaft 7 located between the filter screen 5 and the fixing plate 6, and a fixing frame 10 fixedly connected to the bottom end of the connecting pipe 1, with an opening between the connecting pipe 1 and the fixing frame 10. A connecting port 14 is provided, which communicates with the fixed frame 10 and is positioned corresponding to the filter screen 5. A fixed outer shell 15 is fixedly connected to the inner side of the connecting port 14. A rotating plate 29 is rotatably connected to the lower inner wall of the fixed outer shell 15. Multiple rotating shafts 30 are rotatably connected to the top of the rotating plate 29. A crushing roller 31 is fixedly sleeved on the outer side of each rotating shaft 30. A fixed gear ring 33 is fixedly connected to the inner wall of the fixed outer shell 15. A fixed gear 32 is fixedly sleeved on each rotating shaft 30. Each fixed gear 32 meshes with the fixed gear ring 33. A fixed shaft 7 is fixed with... A bevel gear 13 is fitted, and a bevel gear 12 meshes with it below the bevel gear 13. A connecting shaft 11 is fixedly connected to the bottom end of the bevel gear 12. The connecting shaft 11 passes through the lower inner wall of the connecting pipe 1, and its bottom end is rotatably connected to the lower inner wall of the fixed frame 10. A transmission structure is provided on the connecting shaft 11. After sewage enters the connecting pipe 1, it is filtered by the filter screen 5. The filtered insoluble substances fall into the fixed housing 15. Simultaneously, the sewage flow impacts the impact fan 8, causing it to rotate, which in turn drives the fixed shaft 7 to rotate, causing the bevel gear 13 to rotate, thus engaging the bevel gear 12. The bevel gears 12 and 13 rotate together, driving the connecting shaft 11 to rotate. Under the action of the transmission structure, the rotating plate 29 rotates, driving multiple rotating shafts 30 and the crushing roller 31 to rotate. When the crushing roller 31 rotates, it crushes the falling insoluble matter. At the same time, when the rotating shaft 30 rotates, it will cause the fixed gear 32 to rotate. Under the action of the fixed gear ring 33, the fixed gear 32 will rotate on its own while rotating with the rotating shaft 30, driving the rotating shaft 30 and the crushing roller 31 to rotate on their own, improving the crushing effect of the crushing roller 31. After being crushed, the insoluble matter will flow away with the sewage through the gaps in the filter screen 5 and will not block the connecting pipe 1.

[0026] A sealing cover plate 21 is provided at the top of the fixed housing 15. The sealing cover plate 21 is located on the side of the filter screen 5 away from the fixed scraper 9, and the sealing cover plate 21 is slidably connected to the filter screen 5. The sealing cover plate 21 covers the top of the fixed housing 15. A push block 24 is fixedly connected to the side wall of the sealing cover plate 21 away from the filter screen 5. A push rod 20 is fixedly connected to the bottom end of the push block 24. The push rod 20 extends through the lower inner wall of the connecting pipe 1 and into the inner side of the fixed frame 10. An installation rod 19 is provided on the part of the push rod 20 located inside the fixed frame 10. A connecting rod 22 is fixedly connected to the bottom end of the installation rod 19. A spiral groove is provided on the outer side of the connecting shaft 11. A sliding block is slidably connected to the spiral groove. A sleeve is fitted on the outer side of the connecting shaft 11 that is fixed to the sliding block. The connecting ring 23 and the connecting rod 22 are fixedly connected. In the initial state, the sealing cover 21 is closed and the connecting spring 36 is in a stretched state. At this time, sewage cannot pass through the fixed housing 15. When the connecting shaft 11 rotates, the sliding block will slide in the spiral groove. However, due to the action of the connecting ring 23, the sliding block cannot rotate and will move up and down, thereby driving the connecting rod 22 and the mounting rod 19 to move up and down. As the mounting rod 19 moves upward, it will cause the pushing rod 20 and the pushing block 24 to move upward, allowing the sealing cover 21 to open. Sewage can then flow through the inside of the fixed housing 15, carrying out the crushed particles remaining in the fixed housing 15 and preventing them from remaining inside the fixed housing 15 and affecting the crushing roller 31.

[0027] The sealing cover plate 21 has a connecting groove 26 inside. A threaded rod 25 is rotatably installed on the upper inner wall of the connecting groove 26. The threaded rod 25 extends through the upper inner wall of the connecting groove 26 and extends to the outside of the sealing cover plate 21. A threaded ring 27 corresponding to each threaded rod 25 is fixedly connected to the top of the sealing cover plate 21. Each threaded ring 27 is threadedly connected to one threaded rod 25. One end of each threaded rod 25 located inside the connecting groove 26 is fixedly connected to a suction fan 28. When the sealing cover plate 21 moves upward, the suction fan 28 and the threaded rod 25 move upward accordingly. Under the action of the threaded ring 27, the threaded rod 25 rotates as it moves upward, thereby driving the suction fan 28 to rotate. The rotation of the suction fan 28 generates a suction force, which accelerates the flow of sewage from the fixed outer shell 15 and is beneficial for carrying out the crushed particles.

[0028] An adjustment groove 34 is provided inside the mounting rod 19. A movable plate 35 is slidably connected inside the adjustment groove 34. A connecting spring 36 is fixedly connected to the bottom end of the movable plate 35. The end of the connecting spring 36 away from the movable plate 35 is fixedly connected to the lower inner wall of the adjustment groove 34. The bottom end of the push rod 20 passes through the upper inner wall of the mounting rod 19 and is fixedly connected to the top end of the movable plate 35. When the mounting rod 19 moves upward, the stretched connecting spring 36 will first return to its original state, and then the connecting spring 36 will contract. The movable plate 35 and the push rod 20 will then move upward. When the mounting rod 19 moves downward, the push rod 20 will first move downward until the sealing cover 21 closes. Then the connecting spring 36 will relax and stretch, and its elasticity can assist the sealing of the sealing cover 21.

[0029] The transmission structure includes a rotating rod 16 fixedly connected to the bottom end of the rotating plate 29. The rotating rod 16 extends through the lower inner wall of the fixed housing 15 to the outer side of the fixed housing 15. One end of the rotating rod 16 located on the outer side of the fixed housing 15 is rotatably connected to the lower inner wall of the fixed frame 10. Rotating wheels 17 are fixedly sleeved on both the rotating rod 16 and the connecting shaft 11. The rotating wheels 17 are connected to each other by a transmission belt 18. When the connecting shaft 11 rotates, it drives the corresponding rotating wheel 17 to rotate. Under the action of the transmission belt 18, the other rotating wheel 17 and the rotating rod 16 rotate accordingly, causing the rotating plate 29 to rotate.

[0030] Multiple fixed scrapers 9 are fixedly connected to the fixed shaft 7. Each fixed scraper 9 is attached to the side wall of the filter screen 5 away from the impact fan 8. When the fixed shaft 7 rotates, the fixed scrapers 9 rotate accordingly, scraping off the insoluble impurities and precipitates filtered out by the filter screen 5 and letting them fall into the fixed housing 15. Drainage pipes 2 are fixedly connected to both ends of the connecting pipe 1. Sewage flows into the connecting pipe 1 through the drainage pipes 2 and then flows out.

[0031] In this invention, during use, wastewater flows into the connecting pipe 1 through the drain pipe 2 and then out. Upon entering the connecting pipe 1, the wastewater is first filtered by the filter screen 5. Simultaneously, the flowing wastewater impacts the impact fan 8, causing it to rotate, which in turn rotates the fixed shaft 7. As the fixed shaft 7 rotates, the fixed scraper 9 rotates, scraping off the insoluble impurities and precipitates filtered by the filter screen 5, allowing them to fall into the fixed outer casing 15. The rotation of the fixed shaft 7 causes the second bevel gear 13 to rotate, causing the first bevel gear 12, which meshes with the second bevel gear 13, to rotate as well, driving the connecting shaft 11 to rotate. The rotation of the connecting shaft 11 then drives... The corresponding rotating wheel 17 rotates, and under the action of the transmission belt 18, another rotating wheel 17 and the rotating rod 16 rotate accordingly, causing the rotating plate 29 to rotate. The rotation of the rotating plate 29 drives multiple rotating shafts 30 and the crushing roller 31 to rotate. When the crushing roller 31 rotates, it crushes the falling insoluble matter. At the same time, the rotation of the rotating shaft 30 causes the fixed gear 32 to rotate. Under the action of the fixed gear ring 33, the fixed gear 32 rotates on its own axis while rotating with the rotating shaft 30, driving the rotating shaft 30 and the crushing roller 31 to rotate, improving the crushing effect of the crushing roller 31. Some of the crushed insoluble matter will escape from the gaps in the filter screen 5. The wastewater flows away with the sewage and will not block the connecting pipe 1. When the connecting shaft 11 rotates, the sliding block will slide in the spiral groove. However, due to the action of the connecting ring 23, the sliding block cannot rotate and will move up and down, thereby driving the connecting rod 22 and the mounting rod 19 to move up and down. When the mounting rod 19 moves upward, it will first cause the stretched connecting spring 36 to return to its original state, and then cause the connecting spring 36 to contract, which will then cause the moving plate 35 and the pushing rod 20 to move upward, opening the sealing cover 21. The sewage can then flow through the inside of the fixed housing 15, carrying out the crushed particles remaining in the fixed housing 15, thus preventing... The residue inside the fixed housing 15 affects the crushing roller 31. At the same time, when the sealing cover 21 moves upward, the suction fan 28 and the threaded rod 25 move upward as well. Under the action of the threaded ring 27, the threaded rod 25 rotates as it moves upward, thereby driving the suction fan 28 to rotate. The rotation of the suction fan 28 generates a suction force, which speeds up the flow of sewage from the fixed housing 15 and is beneficial for carrying out the crushed particles. When the mounting rod 19 moves downward, the push rod 20 moves downward first until the sealing cover 21 closes. Then the connecting spring 36 relaxes and stretches, and its elasticity can assist the sealing of the sealing cover 21.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
