Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for titanium alloy processing. Background Technology

[0002] The titanium alloy processing wastewater treatment device is a highly efficient piece of equipment specifically designed to treat highly corrosive and complex wastewater containing titanium metal, waste acids, and alkalis generated during titanium alloy processing. Its core physical treatment unit—the sedimentation tank—effectively removes suspended solids and some impurities from the wastewater through gravity settling, significantly improving water quality and laying a good foundation for subsequent chemical and biological treatment. Meanwhile, most existing sedimentation tanks are equipped with a chain scraper system. This system can push the sediment to one end for collection and treatment when moving at the bottom of the tank, and can push floating debris to one end for cleaning when moving on the surface, further improving wastewater treatment efficiency. In existing technologies, scrapers in chain scraper systems are typically securely connected to the chain via mounting brackets. To ensure effective operation at both the top and bottom of the sedimentation tank, the scrapers are usually designed at a 90-degree angle to the direction of travel. However, this design has limitations: as the scraper moves up and down in the sedimentation tank with the chain, its large water-facing surface significantly interferes with the sedimentation process, affecting the sedimentation effect. Therefore, we propose a wastewater treatment device for titanium alloy processing. Summary of the Invention

[0003] To address the aforementioned technical problems, this application provides a titanium alloy processing wastewater treatment device, including a sedimentation tank and a chain disposed within the sedimentation tank. A mounting base is connected to the chain, and a scraper rotatably mounted on the mounting base is also included. A push plate is mounted on the mounting base, and a linkage is provided between the push plate and the scraper. The linkage is used to drive the scraper to deflect relative to the mounting base when the push plate is moved. A guide rail is provided on the inner wall of the sedimentation tank, and the push plate contacts the guide rail. The guide rail is configured such that when the scraper moves along the sedimentation tank, it is tilted forward when it is at the bottom and top of the sedimentation tank, and when it is on either side of the sedimentation tank, it is parallel to the direction of movement to reduce the water-facing surface.

[0004] In some embodiments, the linkage includes a hollow column fixedly connected to one end of the scraper, a shaft slidably connected to the mounting base, one end of the shaft slidably connected to the push plate, and a sliding column fixedly connected to one end of the shaft slidably connected to the hollow column. The sliding column is slidably connected to the inner wall of the hollow column, a spiral groove is provided on the sliding column, and a shaft 2 with one end located in the spiral groove is fixedly connected to the hollow column for driving the scraper to rotate when the push plate is moved. A sliding protrusion is fixedly connected to the inner wall of the mounting base. A sliding groove is provided on the shaft. One end of the sliding protrusion is located in the sliding groove and is slidably connected to its inner wall to guide and limit the movement of the shaft. One end of the scraper is fixedly connected to a limiting ring, and one end of the shaft passes through the limiting ring. Furthermore, a spring is installed inside the hollow column, with both ends of the spring contacting and abutting against the inner wall of the hollow column and the sliding column, respectively, so that when the sliding column is moved, the spring is compressed and contracts to provide self-recovering force.

[0005] In some embodiments, a universal ball is installed at one end of the push plate, and the guide rail includes a hollow rectangular frame fixedly connected to the side wall of the sedimentation tank. The universal ball contacts and abuts against the hollow rectangular frame. The hollow rectangular frame adopts the same design as the chain track, and a strip-shaped protrusion is provided on one side of the bottom of the sedimentation tank. A slope is provided at the transition between the strip-shaped protrusion and the hollow rectangular frame. A strip-shaped protrusion is provided on one side of the top of the sedimentation tank. A slope is also provided at the transition between the strip-shaped protrusion and the hollow rectangular frame.

[0006] In some embodiments, a collection trough is provided at one corner of the bottom of the sedimentation tank, and a sludge suction pipe is fixedly connected to the sedimentation tank. One end of the sludge suction pipe is located in the collection trough, and the sludge suction pipe is connected to an external water pumping device. A suction pipe is installed at one corner of the top of the sedimentation tank. The suction pipe is connected to an external water pumping device through a conduit, and a through groove is provided on the suction pipe.

[0007] In some embodiments, the sedimentation tank is rotatably connected to four corners of the sedimentation tank, and sprockets are fixedly connected to multiple of the sprockets. The sprockets are connected to chains, and a drive motor is fixedly connected to the sedimentation tank. One end of one of the sprockets passes through the sedimentation tank and is fixed to the output shaft of the drive motor.

[0008] In some embodiments, a rectangular groove is provided on the water-facing side of the scraper, and an elastic rubber sheet is installed in the rectangular groove. Multiple top plates are slidably connected inside the scraper, with one end of each top plate contacting the inner side of the elastic rubber sheet. A transmission component is provided inside the scraper, and the top plate is connected to the mounting base through the transmission component. When the scraper is in a forward tilting posture, the transmission component drives the top plate to move, thereby pushing the elastic rubber sheet to make it wavy. When the scraper is in a posture parallel to the direction of movement, the transmission component drives the top plate to move and retract, so that the elastic rubber sheet returns to its original parallel state.

[0009] In some embodiments, the transmission component includes a slide plate slidably disposed within the scraper. A plurality of right-angled trapezoidal protrusions are uniformly and fixedly connected to one side of the slide plate, and the plurality of right-angled trapezoidal protrusions correspond one-to-one with a plurality of top plates. An arc-shaped protrusion is fixedly connected to the mounting base. The arc-shaped protrusion contacts one end of the slide plate, and one end of the arc-shaped protrusion is also provided with a slope.

[0010] This invention has at least the following beneficial effects: Regardless of whether the scraper moves along the bottom or top of the sedimentation tank, it maintains a forward-leaning posture, thereby reducing the chance of impurities passing over the scraper and improving the cleaning effect. At the same time, when the scraper moves between the bottom and top of the sedimentation tank, it can be switched to a posture parallel to its direction of movement through the cooperation of the guide rail and linkage components, which greatly reduces its water-facing surface and thus reduces the interference to the sedimentation process.

Detailed Implementation

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Please see Figures 1-7 The present invention provides a technical solution: a titanium alloy processing wastewater treatment device, comprising a sedimentation tank 1 and a chain 11 disposed within the sedimentation tank 1. Limiting plates 43 are fixedly connected to the upper and lower ends of the inner wall of the sedimentation tank 1. The limiting plates 43 contact and abut against the inner side of the chain 11, providing support to ensure stable operation of the device. A mounting base 12 is connected to the chain 11. The device also includes: Scraper 2 is rotatably mounted on mounting base 12; Push plate 3 is mounted on mounting base 12, and a linkage 4 is provided between push plate 3 and scraper 2. The linkage 4 is used to drive scraper 2 to deflect relative to mounting base 12 when push plate 3 is moved. The guide rail 5 is installed on the inner wall of the sedimentation tank 1, and the push plate 3 contacts the guide rail 5. The guide rail 5 is configured such that when the scraper 2 moves along the sedimentation tank 1, when the scraper 2 is at the bottom and top of the sedimentation tank 1, the scraper 2 is tilted forward; when the scraper 2 is on both sides of the sedimentation tank 1, the scraper 2 is parallel to the direction of movement. Specifically, regardless of whether the scraper 2 is moving along the bottom or top of the sedimentation tank 1, the scraper 2 is tilted forward, thereby reducing the chance of impurities passing over the scraper 2 and improving the cleaning effect. At the same time, when the scraper 2 moves between the bottom and top of the sedimentation tank 1, it can be switched to a position parallel to its moving direction by the cooperation of the guide rail 5 and the linkage 4, thereby greatly reducing its water-facing surface and reducing the interference to the sedimentation process.

[0015] The linkage 4 includes a hollow column 13 fixedly connected to one end of the scraper 2. A shaft 14 is slidably connected to the mounting base 12. One end of the shaft 14 is fixedly connected to the push plate 3. The other end of the shaft 14 is located inside the hollow column 13 and is fixedly connected to a sliding column 15. The sliding column 15 is slidably connected to the inner wall of the hollow column 13. A spiral groove 16 is provided on the sliding column 15. A shaft 2 17 is fixedly connected to the hollow column 13, with one end located inside the spiral groove 16. The shaft 2 17 is slidably connected to the inner wall of the spiral groove 16. When the shaft 14 moves relative to the mounting base 12, it drives the sliding column 15 to move along the hollow column 13. Then, the spiral groove 16 pushes the shaft 2 17 to drive the hollow column 13 to rotate relative to the mounting base 12, thereby causing the scraper 2 to deflect relative to the mounting base 12. A sliding protrusion 18 is fixedly connected to the inner wall of the mounting base 12, and a sliding groove 19 is provided on the shaft 14. One end of the sliding protrusion 18 is located in the sliding groove 19 and is slidably connected to its inner wall to guide and limit the movement of the shaft 14. One end of the scraper 2 is fixedly connected to a limiting ring 44, and one end of the shaft 14 passes through the limiting ring 44. Specifically, the mounting base 12 is located between the limiting ring 44 and the hollow column 13. Furthermore, a spring 21 is installed inside the hollow column 13. Both ends of the spring 21 contact and abut against the inner wall of the hollow column 13 and the sliding column 15, respectively. This spring 21 is compressed and contracts to provide self-recovering force when the sliding column 15 is moved. Specifically, when the spring 21 is in its normal state, the scraper 2 is parallel to its forward direction. At this time, if a pushing force is applied to the push plate 3, the push plate 3 will simultaneously compress the spring 21, causing it to undergo elastic deformation. Simultaneously, the push plate 3 will also cause the scraper 2 to deflect.

[0016] One end of the push plate 3 is equipped with a universal ball 22. The guide rail 5 includes a hollow rectangular frame 23 fixedly connected to the side wall of the sedimentation tank 1. The universal ball 22 contacts and abuts against the hollow rectangular frame 23. The hollow rectangular frame 23 adopts the same design as the track of the chain 11. A strip-shaped protrusion 24 is provided on one side of the bottom end of the hollow rectangular frame 23. A slope 25 is provided at the transition between the strip-shaped protrusion 24 and the hollow rectangular frame 23. A strip-shaped protrusion 26 is provided on one side of the top end of the hollow rectangular frame 23. A slope 25 is also provided at the transition between the strip-shaped protrusion 26 and the hollow rectangular frame 23. Specifically, as a scraper 2 completes a full circle along the sedimentation tank 1, the omnidirectional ball 22 moves sequentially along a specific path. It first moves along the strip protrusion 24. During this stage, due to the special shape and position of the strip protrusion 24, the scraper 2 is able to maintain a forward-leaning posture.

[0017] When the omnidirectional ball 22 moves from the strip protrusion 24 to the hollow rectangular frame 23 with the help of the inclined surface 25, the guiding effect of the inclined surface 25 will push the push plate 3 to move to a certain displacement, which will in turn cause the scraper 2 to deflect, so that the scraper 2 deflects into an attitude parallel to its moving direction.

[0018] When the omnidirectional ball 22 moves from the hollow rectangular frame 23 back to the strip protrusion 26 via the inclined surface 25, the scraper 2 will deflect again using the same principle, also deflecting into a forward tilting posture. Subsequently, the omnidirectional ball 22 will continue to move along the hollow rectangular frame 23 and the strip protrusion 24, completing the entire cycle process. This process is repeated to achieve comprehensive and efficient cleaning of the sedimentation tank 1.

[0019] A collection trough 27 is provided at one corner of the bottom of the sedimentation tank 1. A sludge suction pipe 28 is fixedly connected to the sedimentation tank 1. One end of the sludge suction pipe 28 is located in the collection trough 27 and is connected to an external water pumping device. Specifically, the scraper 2 is used to push the sediment into the collection trough 27, and then the sludge suction pipe 28 is used to extract the sediment in the collection trough 27. A suction pipe 29 is installed at one corner of the top of the sedimentation tank 1. The suction pipe 29 is connected to an external water pumping device through a conduit. A through groove 31 is provided on the suction pipe 29. Specifically, the scraper 2 is used to push the floating objects to one side of the suction pipe 29, and then the suction pipe 29 uses the through groove 31 to suck up the floating objects.

[0020] The sedimentation tank body 1 is rotatably connected to four corner shafts 32. Each shaft 32 is fixedly connected to a sprocket 33, which is connected to a chain 11. A drive motor 34 is fixedly connected to the sedimentation tank body 1. One end of a shaft 32 passes through the sedimentation tank body 1 and is fixed to the output shaft of the drive motor 34. By starting the drive motor 34, the shaft 32 is rotated, which in turn drives the chain 11 through the sprocket 33, thereby moving the scraper 2.

[0021] A rectangular groove 35 is provided on the water-facing side of the scraper 2. An elastic rubber sheet 36 is installed in the rectangular groove 35. The four sides of the elastic rubber sheet 36 are fixedly connected to the scraper 2. The elastic rubber sheet 36 also has several fixed points on one side of the scraper 2. These fixed points are located between two top plates 37. Multiple top plates 37 are evenly slidably connected inside the scraper 2. One end of the top plate 37 contacts the inner side of the elastic rubber sheet 36. A transmission component 38 is provided inside the scraper 2. The top plate 37 is connected to the mounting base 12 through the transmission component 38. When the scraper 2 is in a forward tilting posture, the transmission component 38 drives the top plate 37 to move, thereby pushing the elastic rubber sheet 36 to make it present a wave shape. When the scraper 2 is in a posture parallel to the direction of movement, the transmission component 38 drives the top plate 37 to move back, so that the elastic rubber sheet 36 returns to its original parallel state. Specifically, when the scraper 2 is tilted forward, the transmission component 38 drives the top plate 37 to move and lift the elastic rubber sheet 36, making it wavy. This shape greatly increases the contact area with the sediment, allowing for more thorough contact and friction with the sediment compared to a normal flat structure, thus more completely scraping away the sediment on the surface of the sedimentation tank 1. When the scraper 2 is in a position parallel to the direction of movement, the transmission component 38 drives the top plate 37 to retract, allowing the elastic rubber sheet 36 to return to a parallel state. This loosens impurities and maintains parallelism, while the water flow generated by the movement of the scraper 2 washes the surface of the rubber sheet, effectively reducing impurity contamination.

[0022] The transmission component 38 includes a slide plate 39 that is slidably disposed in the scraper 2. A plurality of right-angled trapezoidal protrusions 41 are evenly fixedly connected to one side of the slide plate 39, and the plurality of right-angled trapezoidal protrusions 41 correspond one-to-one with a plurality of top plates 37. An arc-shaped protrusion 42 is fixedly connected to the mounting base 12. The arc-shaped protrusion 42 contacts one end of the slide plate 39, and one end of the arc-shaped protrusion 42 is also provided with a slope 25. Specifically, when the scraper 2 is parallel to its forward direction, one end of the slide plate 39 contacts and abuts against the mounting base 12. At this time, the inclined side of the right-angled trapezoidal protrusion 41 contacts and abuts against the top plate 37, so that the elastic rubber sheet 36 is parallel. Subsequently, when the scraper 2 rotates relative to the mounting base 12 to switch to the forward tilting posture, one end of the slide plate 39 slides along the inclined surface 25 on the mounting base 12 to the arc-shaped protrusion 42, thereby pushing the slide plate 39 to move, so as to drive the inclined side of the right-angled trapezoidal protrusion 41 to push the top plate 37 to move, thereby pushing the elastic rubber sheet 36 into a wave shape.
