Description

Technical Field

[0001] This invention relates to the field of water inlet technology, specifically to an easily adjustable vortex water inlet. Background Technology

[0002] Fluidized bed reactors are highly efficient reaction devices that utilize fluidization technology and have wide applications in chemical, environmental protection, energy and other fields. Their core function is to suspend solid catalyst particles through the flow of gas or liquid, forming a dynamic state similar to that of a fluid. In this state, the contact area between the solid, liquid and gas phases is greatly increased, thereby improving the reaction rate and conversion rate.

[0003] In a fluidized bed reactor, the feeder is a key component responsible for uniformly dispersing the liquid to be treated (such as wastewater) into the bed. Existing feeders have the following disadvantages:

[0004] 1) The flow rate is not easy to adjust and control, and a large amount of sulfur powder may overflow from the effluent;

[0005] 2) When the reactor stops running, sulfur powder settles to the bottom and clogs the inlet. This means that each time the reactor is restarted, a larger flow rate and velocity are needed to flush out the sulfur powder deposited in the inlet, increasing the difficulty of operation. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an easily adjustable vortex water inlet to solve the problems mentioned in the background art and facilitate water distribution using the water inlet.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an easily adjustable vortex water inlet device, comprising an inlet pipe and a nozzle connected to the inlet pipe, an mounting plate disposed below the nozzle, and multiple symmetrically arranged inlet components connected to the mounting plate, each inlet component comprising a connecting column and a rotating block, one end of the connecting column being fixedly connected to the nozzle, and the other end of the connecting column being fixedly connected to the rotating block, the rotating block being connected to the mounting plate via the connecting components, the inlet pipe being a Y-shaped pipe, both ends of the inlet pipe passing through the surface of the mounting plate and entering the connecting column, the inlet pipe being connected to the nozzle, the two nozzles connected to the two ends of the inlet pipe being centrally symmetrically arranged, the outlets on the nozzles facing opposite directions, and the nozzles being angled relative to the mounting plate.

[0008] Furthermore, the connecting assembly includes a support block, a bend, and a hose. One end of the support block is rotatably connected to the rotating block, and the support block is fixedly connected to the surface of the mounting plate. A bend is fixedly connected inside the connecting column. One end of the bend is connected to the nozzle, and the other end of the bend is fixedly connected to a hose. The hose and the water inlet pipe are connected through a lifting assembly.

[0009] Furthermore, the lifting assembly includes a sleeve, a connecting pipe, and a tension spring. The top end of the sleeve is connected to a flexible hose, the connecting pipe is slidably connected to the inner wall of the sleeve, the lower end of the connecting pipe is connected to a water inlet pipe, and multiple tension springs are fixedly connected to the surface of the mounting plate. The other end of the tension spring is fixedly connected to the outer wall of the top end of the sleeve.

[0010] Furthermore, the surface of the mounting plate is fixedly connected with 4, 6, or 8 sets of water inlet components, and the bottom surface of the mounting plate is connected with a rotating component.

[0011] Furthermore, the replacement assembly includes a chassis, moving blocks, a motor, a slide rod, a fixed joint, a flow guide joint, and a sealing ring. The chassis is slidably connected to the bottom surface of the mounting plate. Two symmetrically arranged fixed joints are fixedly connected to the surface of the chassis. The fixed joints are fixedly connected to both ends of the water inlet pipe. A flow guide joint is fixedly connected to the bottom end of the connecting pipe. A sealing ring is fixedly connected to the bottom surface of the flow guide joint. A sealing groove corresponding to the position of the sealing ring is opened on the surface of the fixed joint. Multiple moving blocks corresponding to the positions of the nozzles are fixedly connected to the bottom surface of the mounting plate. An annular groove corresponding to the position of the moving blocks is opened on the surface of the chassis. The annular groove is designed as a wavy groove. A motor is fixedly connected to the middle of the chassis. A slide rod is fixedly connected to the output end of the motor. The middle part of the mounting plate is slidably connected to the slide rod. A flange mounting ring is fixedly connected to the bottom surface of the chassis.

[0012] Furthermore, an anti-detachment block is fixedly connected to the top of the slide bar, and the cross-section of the moving block and the annular groove is T-shaped.

[0013] Furthermore, the cross-section of the slide bar is hexagonal.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1) This type of easily adjustable vortex water inlet uses two centrally symmetrical nozzles at a certain angle to the mounting plate to distribute water into the fluidized bed reactor. The two nozzles have opposite water outlet directions, which can form a vortex inside the reactor. This increases the uniformity of the water inlet and promotes the full mixing and fluidization of sulfur powder. It can keep the sulfur powder continuously fluidized and evenly distributed during reactor operation, so that the sulfur powder inside is in the optimal fluidization state and overflow into the reactor outlet water as much as possible. At the same time, when the fluidized bed reactor stops operating, the slightly tilted water inlet will not be blocked by sulfur powder sedimentation.

[0016] 2) Two nozzles are symmetrically arranged on the mounting plate and run and stop simultaneously, so uniform water intake and uniform fluidization can be achieved in the same space area (the same plane), which can make sulfur powder mix evenly. In different spaces, the fluidization intensity decreases stepwise from the bottom to the top of the reactor, which can reduce the overflow of sulfur powder into the effluent.

[0017] 3) When no water is supplied, the nozzle outlet faces downwards to further prevent sulfur powder from settling and clogging the nozzle;

[0018] 4) When one of the nozzles is blocked, the water inlet pipe can be connected to another pair of nozzles through the switching component, thereby ensuring the normal operation of the water inlet. Even if some nozzles are blocked, the system can automatically switch to the backup nozzle through the switching component, thereby avoiding the overall shutdown, improving the operational stability and production efficiency of the equipment, realizing the automatic switching of the water flow path, ensuring that the system can quickly return to normal operation when faced with sudden situations such as nozzle blockage, realizing efficient and leak-free switching between the water inlet pipe and the nozzle, and facilitating the timely adjustment of the nozzle status by the staff.

[0032] 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.

[0033] Please see Figures 1-12 An easily adjustable vortex water inlet includes an inlet pipe 1 and a nozzle 2 connected to the inlet pipe 1. A mounting plate 3 is provided below the nozzle 2. Multiple sets of symmetrically arranged inlet components are connected to the mounting plate 3. Each inlet component includes a connecting column 4 and a rotating block 5. One end of the connecting column 4 is fixedly connected to the nozzle 2, and the other end of the connecting column 4 is fixedly connected to the rotating block 5. The rotating block 5 is connected to the mounting plate 3 through the connecting components. The inlet pipe 1 is Y-shaped. Both ends of the inlet pipe 1 pass through the surface of the mounting plate 3 and enter the connecting column 4. The inlet pipe 1 is connected to the nozzle 2. The two nozzles 2 connected to the two ends of the inlet pipe 1 are centrally symmetrically arranged. The outlets of the nozzles 2 face opposite directions. The nozzles 2 are set at an angle to the mounting plate 3.

[0034] In this invention, the vortex inlet is positioned at an angle between the nozzle 2 and the mounting plate 3, with the included angle between 0 and 90 degrees, and 15 degrees being optimal. Water is introduced into the fluidized bed reactor through two centrally symmetrical nozzles 2 positioned at a certain angle to the mounting plate 3. The two nozzles 2 have opposite outlet directions, creating a vortex inside the reactor. This increases the uniformity of the incoming water and promotes thorough mixing and fluidization of the sulfur powder. During reactor operation, the sulfur powder remains continuously fluidized and evenly distributed, ensuring optimal fluidization and minimizing overflow into the reactor effluent. Furthermore, when the fluidized bed reactor stops operating, the slightly tilted inlet will not become clogged due to sulfur powder sedimentation. The symmetrical arrangement of the two nozzles 2 on the mounting plate 3, operating and stopping simultaneously, ensures uniform water intake and fluidization within the same spatial area (same plane), allowing for uniform mixing of the sulfur powder. In different spaces, the fluidization intensity decreases in a stepped manner from the bottom to the top of the reactor, reducing sulfur powder overflow into the effluent.

[0035] As a preferred technical solution of the present invention, the connecting assembly includes a support block 6, a bend 7 and a hose 8. One end of the support block 6 is rotatably connected to the rotating block 5, and the support block 6 is fixedly connected to the surface of the mounting plate 3. The bend 7 is fixedly connected inside the connecting column 4. One end of the bend 7 is connected to the nozzle 2, and the other end of the bend 7 is fixedly connected to the hose 8. The hose 8 is connected to the water inlet pipe 1 through a lifting assembly.

[0036] Specifically, when no water is introduced, under the action of gravity, the nozzle 2 rotates through the rotating block 5 and the support block 6, so that the outlet of the nozzle 2 faces downward, thereby further preventing sulfur powder from settling and clogging the nozzle 2; when water is introduced, the hose 8 straightens after the water flow, and under the impact of the water, the nozzle 2 will rise, thereby lifting the nozzle 2 until it is set at an angle with the mounting plate 3, so that the water outlet forms an effective vortex, promoting the uniform fluidization and mixing of sulfur powder; the bend 7 and the hose 8 can limit the maximum angle of rotation of the nozzle 2, preventing the nozzle 2 from rotating excessively, and the maximum length of the hose 8 is the highest position that the nozzle 2 can rotate to.

[0037] As a preferred technical solution of the present invention, the lifting assembly includes a sleeve 9, a connecting pipe 10 and a tension spring 11. The top end of the sleeve 9 is connected to the hose 8, the connecting pipe 10 is slidably connected to the inner wall of the sleeve 9, the lower end of the connecting pipe 10 is connected to the water inlet pipe 1, and a plurality of tension springs 11 are fixedly connected to the surface of the mounting plate 3. The other end of the tension spring 11 is fixedly connected to the outer wall of the top end of the sleeve 9.

[0038] Specifically, the connecting pipe 10 is slidably connected to the inner wall of the sleeve 9, and its lower end is connected to the water inlet pipe 1, forming a water flow path that can extend and retract vertically. When the water starts to flow, the pressure and momentum of the water flow will push the sleeve 9 upward, thereby driving the nozzle 2 to adjust its angle. The function of the tension spring 11 is to restore the connecting pipe 10 and the nozzle 2 to their initial positions when there is no water inlet, that is, the outlet of the nozzle 2 faces downward, to prevent material from settling. The outer wall of the tension spring 11 is covered with a hydrophobic coating, thereby reducing the adhesion of water on its surface, avoiding corrosion and rust, and extending the service life of the tension spring 11.

[0039] As a preferred embodiment of the present invention, four, six or eight sets of water inlet components are fixedly connected to the surface of the mounting plate 3, and a rotating component is connected to the bottom surface of the mounting plate 3.

[0040] Specifically, by using multiple sets of water inlet components, when one of the nozzles 2 is blocked, the water inlet pipe 1 can be connected to another pair of nozzles 2 through the switching component, thereby ensuring the normal operation of the water inlet. Even if some nozzles 2 are blocked, the system can automatically switch to the backup nozzle 2 through the switching component, thereby avoiding overall shutdown and improving the operational stability and production efficiency of the equipment.

[0041] As a preferred embodiment of the present invention, the rotating assembly includes a chassis 12, a moving block 15, a motor 16, a slide rod 17, a fixed joint 18, a flow guide joint 19, and a sealing ring 20. The chassis 12 is slidably connected to the bottom surface of the mounting plate 3. Two symmetrically arranged fixed joints 18 are fixedly connected to the surface of the chassis 12. The fixed joints 18 are fixedly connected to both ends of the water inlet pipe 1. The flow guide joint 19 is fixedly connected to the bottom end of the connecting pipe 10. The sealing ring 20 is fixedly connected to the bottom surface of the flow guide joint 19. A sealing groove 21 corresponding to the position of the sealing ring 20 is opened on the surface of the fixed joint 18. Multiple moving blocks 15 corresponding to the positions of the nozzles 2 are fixedly connected to the bottom surface of the mounting plate 3. An annular groove 14 corresponding to the position of the moving block 15 is opened on the surface of the chassis 12. The annular groove 14 is a wavy groove. The motor 16 is fixedly connected to the middle of the chassis 12. The slide rod 17 is fixedly connected to the output end of the motor 16. The middle part of the mounting plate 3 is slidably connected to the slide rod 17. A flange mounting ring 13 is fixedly connected to the bottom surface of the chassis 12.

[0042] Specifically, when it is necessary to replace the nozzle 2 connected to the inlet pipe 1, the motor 16 starts and drives the slide rod 17 to rotate, which in turn drives the mounting plate 3 to rotate. At this time, the moving block 15 will slide in the annular groove 14. The moving block 15 will first move from the trough to the crest. At this time, the moving block 15 is pushed up by the bottom surface of the annular groove 14, which in turn drives the mounting plate 3 to slide on the slide rod 17, causing the flow guide 19 to rise, so that the sealing ring 20 separates from the sealing groove 21. Then the moving block 15 moves from the trough to the crest again. At this time, the other flow guide 19 will gradually approach the fixed joint 18. When the moving block 15 moves to the trough again, the motor 16 stops. With the cooperation of the moving block 15 and the annular groove 14, the mounting plate 3 and the chassis 12 are pressed together, and the flow guide 1... Aligning the 9 with the fixed joint 18, the sealing ring 20 enters the sealing groove 21. At this time, under the action of the sealing ring 20, the connection between the guide joint 19 and the fixed joint 18 is sealed, thereby allowing the nozzle 2 to reconnect with the water inlet pipe 1, thus realizing the rotation of the nozzle 2; the flange mounting ring 13 is used to connect the chassis 12 to the fluidized bed reactor; the connection between the mounting plate 3 and the chassis 12 and the slide rod 17 is provided with a sealing sleeve to improve the waterproof effect on the motor 16 and improve the stability of the entire device operation; during the rotation of the mounting plate 3, the complete annular groove 14 can ensure that all moving blocks 15 are in contact with the bottom surface of the annular groove 14, thereby providing better stability for the mounting plate 3 and ensuring the stable rotation and lifting of the mounting plate 3;

[0043] This setup enables automatic switching of the water flow path, ensuring that the system can quickly return to normal operation when faced with emergencies such as nozzle 2 blockage. It achieves efficient and leak-free switching between the inlet pipe 1 and nozzle 2, facilitating timely adjustment of the nozzle 2's status by staff.

[0044] As a preferred technical solution of the present invention, the top of the slide bar 17 is fixedly connected with an anti-detachment block 22, and the cross-section of the moving block 15 and the annular groove 14 is T-shaped, so that the two ends of the lower part of the moving block 15 can be slidably disposed on both sides of the annular groove 14.

[0045] Specifically, the anti-detachment block 22 prevents the mounting plate 3 from accidentally falling off during rotation or sliding, ensuring the stability of the component during high-speed operation or when subjected to external interference, and improving the safety and durability of the entire system. The moving block 15 and the annular groove 14 adopt a T-shaped cross-section design, so that the lower ends of the moving block 15 are slidably set inside the bottom sides of the annular groove 14. This design increases the contact area between the two, providing stronger guidance and stability. The T-shaped structure can not only guide the moving block 15 to slide smoothly in the annular groove 14, but also effectively prevent the moving block 15 from shifting laterally, ensuring precise alignment during the nozzle 2 switching process, and improving the accuracy and efficiency of adjustment. The combined use of the anti-detachment block 22 and the T-shaped cross-section significantly enhances the reliability of the switching component under dynamic conditions. Even under frequent switching and long-term operation, the system can still maintain high stability and accuracy, reducing the failure rate caused by mechanical wear or positioning errors.

[0046] As a preferred embodiment of the present invention, the cross-section of the slide bar 17 is hexagonal.

[0047] Specifically, designing the cross-section of the slide rod 17 as hexagonal ensures that the slide rod 17 can stably drive the mounting plate 3 to rotate and slide, ensuring the accuracy and efficiency of transmission. At the same time, compared with a circular cross-section, the hexagonal cross-section has higher bending and torsional rigidity under the same material and size. This means that when the slide rod 17 bears the torque output by the motor 16 and the weight of the mounting plate 3, it can maintain better straightness and rotational stability, reduce deformation, and extend service life.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
