Description

Technical Field

[0001] This invention relates to the field of mud purifier technology, specifically a mud purifier based on building construction. Background Technology

[0002] Mud purifiers, also known as mud separators or mud dewatering machines, are solids control devices used for mud treatment in engineering construction. These devices are widely used in railway bridge pile foundations, tunnel shields, oil drilling, and municipal subway continuous wall projects. They are suitable for forward and reverse circulation drilling and slurry shield tunneling methods. Their core components include a vibrating screen, mud pump, hydrocyclone, and intelligent control system. Through coarse screening dewatering and centrifugal separation technologies, they achieve mud recycling. The modular design includes a coarse vibrating screen, sand removal, and mud removal modules, allowing for the reuse of purified mud and reducing emissions.

[0003] The treatment effect of mud purifiers is closely related to the mud concentration. The equipment usually requires the mud concentration to be within a certain range to achieve efficient separation. However, the mud concentration is uncontrollable. When treating high-concentration mud, the high content of solid particles in the mud can easily accelerate the wear of key components such as hydrocyclones and screens in the purifier. Moreover, viscous mud can easily adhere to the inner wall of the pipe, reducing the flow rate or even completely blocking it, thus reducing the separation efficiency. Furthermore, if the mud contains large particles, these particles can easily collide with the screen during mud suction, causing problems such as screen deformation and holes, reducing the service life of the equipment, and easily leading to construction interruptions.

[0004] Therefore, based on the above problems, we invented a mud purifier based on building construction. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a mud purifier based on building construction to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mud purifier based on building construction, comprising a purifier body, a proportioning box provided inside the purifier body, the proportioning box being installed to the purifier body via a fixing plate, two partitions fixedly installed inside the proportioning box, a proportioning mechanism for proportioning mud and water provided between the two partitions, a cleaning box outside the purifier body, a transition pipe installed at the upper end of the cleaning box, the transition pipe penetrating the purifier body and connected to the proportioning box, a suction pipe installed at the lower end of the cleaning box, a cleaning mechanism for cleaning large particulate impurities in the mud provided inside the cleaning box, and the cleaning box being fixedly installed to the outer wall of the purifier body.

[0007] Furthermore, the proportioning mechanism includes two turntables, each of which rotatably passes through two partitions. A rotating shaft is coaxially mounted on the opposite ends of each partition. Both rotating shafts rotatably pass through a proportioning box. A transition shaft rotatably passes through the proportioning box and is connected to the two rotating shafts via a transmission mechanism. Multiple rotating tubes are rotatably mounted between the two turntables. Both ends of each rotating tube rotatably pass through the two turntables and are coaxially mounted with rotating gears. The inner wall of each partition has an annular toothed groove that meshes with the rotating gears. A fixed shaft is located inside each rotating tube. Both ends of the fixed shaft rotatably pass through the rotating gears and are fixedly connected to a water-filling plate. The water-filling plate is fixedly connected to the rotating shaft. A connecting key is fixedly mounted outside the rotating tube. A stirring blade is rotatably mounted on the connecting key. One end of the stirring blade is fixedly connected to a drive shaft. The drive shaft rotatably passes through the connecting key and the rotating tube and is connected to the fixed shaft via a gear transmission mechanism.

[0008] Furthermore, the transmission mechanism includes a second pulley and a first pulley. The second pulley is coaxially mounted with the rotating shaft, and the first pulley is coaxially mounted with the transition shaft. The second pulley and the first pulley are connected by a synchronous belt drive. A protective cover matching the second pulley and the first pulley is installed outside the proportioning box.

[0009] Furthermore, the gear transmission mechanism includes a gear disk and a transmission gear. The gear disk is coaxially mounted with a fixed shaft, and the transmission gear is coaxially mounted with a drive shaft. The gear disk and the transmission gear are meshed together.

[0010] Furthermore, a water-transfer ring is fixedly installed on the outside of the fixed shaft. An annular groove is provided on the outer wall of the water-transfer ring. A sealing rotating ring is rotatably installed on the outer side of the annular groove. A water-transfer pipe is connected through the sealing rotating ring. The water-transfer pipe is fixedly connected through the rotating pipe and the connecting key and communicates with the stirring blade. A water outlet is installed on the stirring blade and communicates with the water-transfer pipe. A water inlet is provided on the rotating shaft. The water inlet is connected to the annular groove through the water-filling plate, the fixed shaft, and the water-transfer ring.

[0011] Furthermore, the cleaning mechanism includes a rotating column rotatably installed inside the cleaning box, a cleaning shaft coaxially mounted on the rotating column, multiple cleaning plates mounted outside the rotating column, filter screens installed between the multiple cleaning plates, a shielding filter screen mounted on the top of the rotating column, the shielding filter screen matching the transition tube, a useful collection trough installed at the lower end of the cleaning box, the collection trough communicating with the inside of the cleaning box, one end of the transition shaft rotatably passing through the purifier body and rotatably mounted to the cleaning box through a bearing seat, the transition shaft and the cleaning shaft being connected by a second bevel gear set, a power motor mounted at the upper end of the cleaning box, and the drive shaft of the power motor being connected to the transition shaft by a first bevel gear set.

[0012] Furthermore, the first bevel gear set includes a first bevel gear and a second bevel gear that mesh with each other. The first bevel gear is coaxially mounted with the drive shaft of the power motor, and the second bevel gear is coaxially mounted with the transition shaft.

[0013] Furthermore, the second bevel gear set includes a third bevel gear and a fourth bevel gear that mesh with each other. The third bevel gear is coaxially mounted with the transition shaft, and the fourth bevel gear is coaxially mounted with the cleaning shaft.

[0014] Furthermore, the multiple rotating tubes are arranged in a ring array on the turntable.

[0015] Compared with the prior art, the present invention provides a mud purifier based on construction, which has the following beneficial effects: 1. By setting up a cleaning mechanism, before the mud enters the purifier, it passes through the rotating filter and shielding filter in the cleaning box to intercept large particles of impurities, preventing impurities from entering the purifier, greatly reducing the equipment failure rate and extending the service life of the equipment.

[0016] 2. By setting a proportioning mechanism, water is added online to dilute the slurry according to its actual concentration, and the high-viscosity slurry is adjusted to the appropriate processing range of the equipment. This avoids the viscous slurry sticking to the walls and clogging the pipes, reducing the separation efficiency of the slurry, and maintaining the purification effect of the slurry. Water can be added and stirred from inside the slurry. During the water addition process, the water will not accumulate. The water is added evenly, which improves the proportioning efficiency of the slurry.

[0017] This application can remove large particles of impurities from the mud, extend the service life of the equipment, and can also uniformly add water to the mud, improving the mud mixing efficiency. Attached Figure Description

[0020] 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.

[0021] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a mud purifier based on building construction.

[0022] like Figures 1-9 As shown, a mud purifier based on building construction includes a purifier body 1, a mixing tank 2 inside the purifier body 1, the mixing tank 2 being installed to the purifier body 1 via a fixing plate 3, two partitions 9 being fixedly installed inside the mixing tank 2, and a mixing mechanism 4 for mixing mud and water between the two partitions 9, a cleaning tank 6 outside the purifier body 1, a transition pipe 5 being installed at the upper end of the cleaning tank 6, the transition pipe 5 passing through the purifier body 1 and connecting to the mixing tank 2, a suction pipe 7 being installed at the lower end of the cleaning tank 6, and a cleaning mechanism 8 for cleaning large particulate impurities in the mud inside the cleaning tank 6, the cleaning tank 6 being fixedly installed to the outer wall of the purifier body 1.

[0023] To ensure the proper mud proportions, a proportioning mechanism 4 is installed. The proportioning mechanism 4 includes two turntables 10, each rotatably passing through two partitions 9. A rotating shaft 11 is coaxially mounted on the opposite ends of each partition 9. Both rotating shafts 11 rotatably pass through a proportioning box 2. A transition shaft 12 rotatably passes through the proportioning box 2. The transition shaft 12 is connected to the two rotating shafts 11 via a transmission mechanism 13. Notably, the transmission mechanism 13 includes a second pulley 14 and a first pulley 45. The second pulley 14 is coaxially mounted with the rotating shaft 11, and the first pulley 45 is coaxially mounted with the transition shaft 12. The second pulley 14 and the first pulley 45 are connected by a synchronous belt. A protective cover 15 matching the second pulley 14 and the first pulley 45 is installed outside the proportioning box 2. Multiple rotating tubes 18 are rotatably mounted between the two turntables 10. It should be noted that the multiple rotating tubes 18 are arranged in a circular array on the turntables 10. The rotating tube 18 is rotatably connected to two turntables 10 at both ends. Rotating gears 19 are coaxially mounted at both ends of the rotating tube 18. The inner wall of the partition plate 9 is provided with annular toothed grooves that mesh with the rotating gears 19. A fixed shaft 17 is provided inside the rotating tube 18. Both ends of the fixed shaft 17 rotatably pass through the rotating gears 19 and are fixedly connected to water filling plates 16. Water filling plates 16 are fixedly connected to the rotating shaft 11. A connecting key 21 is fixedly mounted outside the rotating tube 18. A stirring blade 20 is rotatably mounted on the connecting key 21. One end of the stirring blade 20 is fixedly connected to a drive shaft 22. The drive shaft 22 rotatably passes through the connecting key 21 and the rotating tube 18 and is connected to the fixed shaft 17 through a gear transmission mechanism 23. Further, the gear transmission mechanism 23 includes a gear disk 24 and a transmission gear 25. The gear disk 24 is coaxially mounted with the fixed shaft 17, and the transmission gear 25 is coaxially mounted with the drive shaft 22. The gear disk 24 and the transmission gear 25 are meshed together.

[0024] In this invention, a water-transfer ring 26 is fixedly installed on the outside of the fixed shaft 17. An annular groove 28 is provided on the outer wall of the water-transfer ring 26. A sealing rotating ring 29 is rotatably installed on the outer side of the annular groove 28. A water-transfer pipe 27 is connected through the sealing rotating ring 29. The water-transfer pipe 27 is fixedly connected through the rotating pipe 18 and the connecting key 21 and communicates with the stirring blade 20. A water outlet 46 is installed on the stirring blade 20 and communicates with the water-transfer pipe 27. A water inlet hole 44 is provided on the rotating shaft 11. The water inlet hole 44 communicates with the annular groove 28 through the water-filling plate 16, the fixed shaft 17 and the water-transfer ring 26.

[0025] Through the aforementioned technical features: the power motor 38 drives the transition shaft 12 to rotate, the transition shaft 12 drives two rotating shafts 11 to rotate, the two rotating shafts 11 drive two turntables 10 to rotate, the two turntables 10 drive multiple rotating tubes 18 to rotate, and the multiple rotating tubes 18 drive multiple stirring blades 20 to revolve around the central axis of the rotating shaft 11. At the same time, under the action of the rotating gear 19 and the annular toothed groove, the rotating gear 19 rotates on its own axis, the rotating gear 19 drives the rotating tubes 18 to rotate on their own axis, and the rotating tubes 18 drive the stirring blades 20 to revolve around the central axis of the rotating tubes 18. That is, at this time, the rotating tubes 18 rotate relative to the fixed shaft 17. The rotating pipe 18 drives the transmission gear 25 to revolve through the drive shaft 22. At this time, the gear disk 24 drives the transmission gear 25 to rotate under the action of the tooth groove. The transmission gear 25 drives the stirring blade 20 to rotate through the drive shaft 22. Water is injected through the water inlet hole 44 on the shaft 11. The water flows through the shaft 11, water inlet plate 16, fixed shaft 17, water-transfer ring 26, and water-transfer pipe 27 into the stirring blade 20 and flows out through the water outlet 46. Water can be added inside the mud and stirred at the same time, which can quickly improve the cement ratio of the mud. It is more convenient to improve the mud ratio and can quickly improve the uniformity of the mud.

[0026] To remove large particles of impurities from the mud, a cleaning mechanism 8 is provided. The cleaning mechanism 8 includes a rotating column 31 rotatably mounted inside the cleaning box 6. A cleaning shaft 32 is coaxially mounted on the rotating column 31. Multiple cleaning plates 33 are mounted outside the rotating column 31, and filter screens 34 are installed between the cleaning plates 33. A shielding filter screen 35 is installed at the top of the rotating column 31, and the shielding filter screen 35 matches the transition pipe 5. A useful collection trough 36 is installed at the lower end of the cleaning box 6, and the collection trough 36 is connected to the inside of the cleaning box 6. One end of the transition shaft 12 rotatably passes through the purifier body 1 and is rotatably mounted to the cleaning box 6 via a bearing seat 30. The transition shaft 12 and the cleaning shaft 32 are connected... The second bevel gear set 39 is connected by transmission. Further, the second bevel gear set 39 includes a third bevel gear 42 and a fourth bevel gear 43 that mesh with each other. The third bevel gear 42 is coaxially mounted with the transition shaft 12, and the fourth bevel gear 43 is coaxially mounted with the cleaning shaft 32. A power motor 38 is installed at the upper end of the cleaning box 6. The drive shaft of the power motor 38 is connected to the transition shaft 12 by transmission through the first bevel gear set 37. It should be noted that the first bevel gear set 37 includes a first bevel gear 40 and a second bevel gear 41 that mesh with each other. The first bevel gear 40 is coaxially mounted with the drive shaft of the power motor 38, and the second bevel gear 41 is coaxially mounted with the transition shaft 12.

[0027] Through the above technical features: the transition shaft 12 drives the cleaning shaft 32 to rotate, the cleaning shaft 32 drives the rotating column 31 to rotate, the rotating column 31 drives the cleaning plate 33 to rotate, and the cleaning plate 33 drives the filter screen 34 and the shielding filter screen 35 to rotate. When the mud is extracted, large particles of impurities in the mud enter the cleaning box 6. Due to the obstruction of the shielding filter screen 35, the impurities cannot enter the transition pipe 5. At this time, the filter screen 34 pushes the impurities, causing them to move to the inside of the cleaning box 6. Since the impurities are not subjected to upward thrust, they will fall into the collection tank 36 under the action of gravity. Then, the collection tank 36 can be replaced after a period of time to complete the cleaning of impurities in the mud. The cleaning of impurities is relatively convenient.

[0028] Working principle: 1) Cleaning of mud impurities: The power motor 38 drives the transition shaft 12 to rotate, which in turn drives the cleaning shaft 32 to rotate. The cleaning shaft 32 drives the rotating column 31 to rotate, which in turn drives the cleaning plate 33 to rotate. The cleaning plate 33 drives the filter screen 34 and the shielding filter screen 35 to rotate. When the mud is being extracted, large particles of impurities in the mud enter the cleaning box 6. Due to the obstruction of the shielding filter screen 35, the impurities cannot enter the transition pipe 5. At this time, the filter screen 34 pushes the impurities to the inside of the cleaning box 6. Since the impurities are not pushed upward, they will fall into the collection tank 36 under the action of gravity. The collection tank 36 can be replaced after a period of time to complete the cleaning of impurities in the mud. The cleaning of impurities is relatively convenient. 2) Mud slurry proportioning and mixing: The transition shaft 12 drives two rotating shafts 11 to rotate, the two rotating shafts 11 drive two rotating disks 10 to rotate, the two rotating disks 10 drive multiple rotating tubes 18 to rotate, and the multiple rotating tubes 18 drive multiple stirring blades 20 to revolve around the central axis of the rotating shaft 11. At the same time, under the action of the rotating gear 19 and the annular tooth groove, the rotating gear 19 rotates on its own axis, and the rotating gear 19 drives the rotating tubes 18 to rotate on their own axis. The rotating tubes 18 drive the stirring blades 20 to revolve around the central axis of the rotating tubes 18. That is, at this time, the rotating tubes 18 rotate relative to the fixed shaft 17. The rotating tubes 18 drive the stirring blades 20 to revolve around the central axis of the rotating tubes 18. The rotating shaft 22 drives the transmission gear 25 to revolve. At this time, the gear disk 24 drives the transmission gear 25 to rotate under the action of the tooth groove. The transmission gear 25 drives the stirring blade 20 to rotate through the driving shaft 22. Water is injected through the water inlet hole 44 on the rotating shaft 11. The water flows through the rotating shaft 11, the water inlet plate 16, the fixed shaft 17, the water-transfer ring 26, and the water-transfer pipe 27 into the stirring blade 20 and flows out through the water outlet 46. Water can be added inside the mud and stirred at the same time, which can quickly improve the cement ratio of the mud. It is more convenient to improve the mud ratio and can quickly improve the uniformity of the mud.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

All equivalent implementation methods or modifications made without departing from the spirit of the art of this application should be included within the scope of protection of this invention.
