Description

Technical Field

[0001] The invention relates to the technical field of water inlets, in particular to an easily adjustable cyclone water inlet. Background Art

[0002] A fluidized bed reactor is a highly efficient reaction device that utilizes fluidization technology. It is widely used in chemical industry, environmental protection, energy and other fields. Its core is to suspend solid catalyst particles through the flow of gas or liquid to form 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 water inlet is a key component responsible for evenly dispersing the liquid to be treated (such as wastewater) into the bed. The existing water inlet has the following disadvantages:

[0004] 1) The flow rate is difficult to adjust and control, and a large amount of sulfur powder may overflow into the water;

[0005] 2) When the reactor stops running, the sulfur powder settles to the bottom and blocks the water inlet, resulting in the need to use a larger flow rate and velocity to flush out the sulfur powder deposited in the water inlet each time the reactor is restarted, increasing the difficulty of operation. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides an easily adjustable cyclone water inlet to solve the problems raised in the background art and facilitate water distribution using the water inlet.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an easily adjustable swirl water inlet, comprising a water inlet pipe and a nozzle connected to the water inlet pipe, a mounting plate is arranged below the nozzle, and a plurality of symmetrically arranged water inlet components are connected to the mounting plate, each group of water inlet components comprises a connecting column and a rotating block, one end of the connecting column is fixedly connected to the nozzle, and the other end of the connecting column is fixedly connected to the rotating block, the rotating block and the mounting plate are connected through a connecting assembly, the water inlet pipe is a Y-shaped pipe, both ends of the water inlet pipe are passed through the surface of the mounting plate and enter the connecting column, the water inlet pipe is connected to the nozzle, and the two nozzles connected at both ends of the water inlet pipe are centrally symmetrically arranged, the water outlets on the nozzles face opposite directions, and the nozzles and the mounting plate are arranged at an angle.

[0008] Furthermore, the connecting assembly includes a support block, a bent pipe and a hose. One end of the support block is rotatably connected to the rotating block, the support block is fixedly connected to the surface of the mounting plate, a bent pipe is fixedly connected in the connecting column, one end of the bent pipe is connected to the nozzle, and the other end of the bent pipe is fixedly connected to the 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 the hose, the connecting pipe is slidably connected to the inner wall of the sleeve, the lower end of the connecting pipe is connected to the water inlet pipe, and a plurality of 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, 4, 6 or 8 groups of water inlet components are fixedly connected to the surface of the mounting plate, and a rotation component is connected to the bottom surface of the mounting plate.

[0011] Furthermore, the rotation assembly includes a chassis, a moving block, a motor, a sliding rod, a fixed joint, a diversion joint and a sealing ring. The bottom surface of the mounting plate is slidably connected to the chassis, and two symmetrically arranged fixed joints are fixedly connected to the surface of the chassis. The fixed joints are respectively fixedly connected to the two ends of the water inlet pipe, and the bottom end of the connecting pipe is fixedly connected to the diversion joint, and the bottom surface of the diversion joint is fixedly connected to the sealing ring. A sealing groove corresponding to the position of the sealing ring is provided on the surface of the fixed joint, and a plurality of moving blocks corresponding to the nozzle positions are fixedly connected to the bottom surface of the mounting plate, and an annular groove corresponding to the position of the moving block is provided on the surface of the chassis, and the annular groove is arranged in a wavy groove. The middle part of the chassis is fixedly connected to the motor, and the output end of the motor is fixedly connected to the sliding rod. The middle part of the mounting plate is slidably connected to the sliding rod, and the bottom surface of the chassis is fixedly connected to a flange mounting ring.

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

[0013] Furthermore, the cross section of the sliding rod is hexagonal.

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

[0015] 1) This easily adjustable cyclone water inlet distributes water into the fluidized bed reactor through two centrally symmetrical nozzles at a certain angle to the mounting plate. The two nozzles discharge water in opposite directions, forming a cyclone inside the reactor, which not only increases the uniformity of the water inlet, but also promotes the full mixing and fluidization of the sulfur powder. When the reactor is running, the sulfur powder can be continuously fluidized and evenly distributed, so that the internal sulfur powder is in the best fluidized state and overflow into the reactor outlet water is avoided as much as possible. At the same time, when the fluidized bed reactor stops running, the slightly inclined water inlet will not be blocked due to the precipitation of sulfur powder;

[0016] 2) Two nozzles are symmetrically arranged on the mounting plate, and they run and stop at the same time, so that uniform water inflow and uniform fluidization can be achieved in the same spatial area (same plane), and the sulfur powder can be evenly mixed. In different spaces, the fluidization intensity decreases in a step-like manner from the bottom to the top of the reactor, which can reduce the overflow of sulfur powder into the effluent water;

[0017] 3) When no water is introduced, the water outlet of the nozzle faces downward, thereby further preventing sulfur powder from precipitating and clogging the nozzle;

[0018] 4) When one of the nozzles is clogged, the water inlet pipe can be connected to the other pair of nozzles through the rotation component to ensure the normal operation of the water inlet. Even if some nozzles are clogged, the system can automatically switch to the spare nozzle through the rotation component, thereby avoiding overall shutdown, improving the operating stability and production efficiency of the equipment, and realizing automatic switching of the water flow path, ensuring that the system can quickly return to normal operation when faced with emergencies such as nozzle clogs, and realizing efficient and leak-free switching between the water inlet pipe and the nozzle, which is convenient for the staff to adjust the status of the nozzle in time.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] See also Figure 1-Figure 12 , an easily adjustable swirl water inlet, comprising a water inlet pipe 1 and a nozzle 2 connected to the water inlet pipe 1, a mounting plate 3 is arranged below the nozzle 2, and a plurality of symmetrically arranged water inlet components are connected to the mounting plate 3, each group of water inlet components comprises 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 and the mounting plate 3 are connected through a connecting component, the water inlet pipe 1 is a Y-shaped pipe, both ends of the water inlet pipe 1 are penetrated by the surface of the mounting plate 3 and enter the connecting column 4, the water inlet pipe 1 is connected to the nozzle 2, the two nozzles 2 connected at both ends of the water inlet pipe 1 are centrally symmetrically arranged, the water outlets on the nozzles 2 face opposite directions, and the nozzles 2 and the mounting plate 3 are arranged at an angle.

[0034] In the swirl water inlet of the present invention, the nozzle 2 is set at an angle with the mounting plate 3, and the angle is between 0-90 degrees, and 15 degrees is optimal; the water is distributed into the fluidized bed reactor through two centrally symmetrical nozzles 2 with a certain angle to the mounting plate 3, and the water outlet directions of the two nozzles 2 are opposite, so that a swirl can be formed inside the reactor, which not only increases the uniformity of the water inlet, but also promotes the full mixing and fluidization of the sulfur powder, and can make the sulfur powder continuously fluidized and evenly distributed when the reactor is running, so that the internal sulfur powder is in the best fluidized state and avoids overflowing into the reactor outlet water as much as possible, and when the fluidized bed reactor stops running, the slightly inclined water inlet will not be blocked by the precipitation of sulfur powder; two nozzles 2 are symmetrically arranged on the mounting plate 3, and run and stop at the same time, so that uniform water inlet and uniform fluidization can be achieved in the same spatial area (same plane), and the sulfur powder can be evenly mixed, and 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 outlet water.

[0035] As a preferred technical solution of the present invention, the connecting assembly includes a support block 6, a curved pipe 7 and a hose 8. One end of the support block 6 is rotatably connected to the rotating block 5, the support block 6 is fixedly connected to the surface of the mounting plate 3, a curved pipe 7 is fixedly connected to the connecting column 4, one end of the curved pipe 7 is connected to the nozzle 2, and the other end of the curved pipe 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 supporting block 6, so that the water outlet of the nozzle 2 faces downward, thereby further preventing the sulfur powder from settling and clogging the nozzle 2; when water is introduced, the hose 8 becomes straight after the water flow is introduced, and under the impact of the incoming 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 outlet water forms an effective vortex, promoting the uniform fluidization and mixing of the sulfur powder; the elbow 7 and the hose 8 can limit the maximum rotation angle of the nozzle 2 to prevent the nozzle 2 from rotating excessively. The maximum length of the hose 8 is the highest position to which the nozzle 2 can rotate.

[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. 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 the lower end is connected to the water inlet pipe 1, forming a water flow path that can be extended and retracted up and down. When the incoming water starts to flow, the pressure and momentum of the water flow will push the sleeve 9 to move upward, thereby driving the nozzle 2 to adjust the angle. The function of the tension spring 11 is to restore the connecting pipe 10 and the nozzle 2 to their initial positions through its elastic force when there is no water inflow, that is, the water outlet of the nozzle 2 faces downward to prevent material deposition; 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 technical solution of the present invention, 4, 6 or 8 groups of water inlet components are fixedly connected to the surface of the mounting plate 3, and a rotation 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 rotation component, thereby ensuring the normal operation of the water inlet; even when some of the nozzles 2 are blocked, the system can automatically switch to the spare nozzles 2 through the rotation component, thereby avoiding overall shutdown and improving the operating stability and production efficiency of the equipment.

[0041] As a preferred technical solution of the present invention, the rotation component includes a chassis 12, a moving block 15, a motor 16, a slide rod 17, a fixed joint 18, a diversion joint 19 and a sealing ring 20. The bottom surface of the mounting plate 3 is slidably connected to the chassis 12, and two symmetrically arranged fixed joints 18 are fixedly connected to the surface of the chassis 12. The fixed joints 18 are respectively fixedly connected to the two ends of the water inlet pipe 1, and the bottom end of the connecting pipe 10 is fixedly connected to the diversion joint 19. The bottom surface of the diversion joint 19 is fixedly connected to the sealing ring 20. A sealing groove 21 corresponding to the position of the sealing ring 20 is provided on the surface of the fixed joint 18. A plurality of moving blocks 15 corresponding to the position of the nozzle 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 provided on the surface of the chassis 12. The annular groove 14 is a wavy groove setting. The motor 16 is fixedly connected to the middle part of the chassis 12, and the output end of the motor 16 is fixedly connected to the slide rod 17. The middle part of the mounting plate 3 is slidably connected to the slide rod 17, and the bottom surface of the chassis 12 is fixedly connected to the flange mounting ring 13.

[0042] Specifically, when the nozzle 2 connected to the water inlet pipe 1 needs to be replaced, the motor 16 starts to drive the slide bar 17 to rotate, and then drives the mounting plate 3 to rotate. At this time, the moving block 15 will slide in the annular groove 14, and 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, and then drives the mounting plate 3 to slide on the slide bar 17, driving the diversion joint 19 to rise, so that the sealing ring 20 is separated from the sealing groove 21, and then the moving block 15 moves from the trough to the crest again. At this time, the other diversion joint 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 tightly, and the diversion joint 1 9 is aligned with the fixed joint 18, and 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, so that the nozzle 2 is connected to the water inlet pipe 1 again, and the rotation of the nozzle 2 can be realized; the flange mounting ring 13 is used to connect the chassis 12 with the fluidized bed reactor; the connection between the mounting plate 3 and the chassis 12 and the slide bar 17 is provided with a sealing sleeve to improve the waterproof effect of the motor 16 and improve the stability of the operation of the entire device; during the rotation of the mounting plate 3, the complete annular groove 14 can ensure that all the 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] Through this setting, automatic switching of the water flow path is achieved, ensuring that the system can quickly return to normal operation when faced with emergencies such as blockage of nozzle 2, and achieving efficient and leak-free switching between the water inlet pipe 1 and the nozzle 2, making it convenient for staff to adjust the status of the nozzle 2 in a timely manner.

[0044] As a preferred technical solution of the present invention, an anti-drop block 22 is fixedly connected to the top of the slide rod 17, and the cross-section of the moving block 15 and the annular groove 14 is T-shaped to enable the lower ends of the moving block 15 to be slidably arranged on both sides of the annular groove 14.

[0045] Specifically, the anti-slip block 22 can prevent the mounting plate 3 from accidentally falling off during rotation or sliding, ensures the stability of the component when running at high speed or being disturbed by external forces, and improves 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 two ends of the moving block 15 are slidably arranged on both sides of the bottom of the annular groove 14. This design increases the contact area between the two and provides 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 lateral displacement of the moving block 15, ensuring the precise alignment of the nozzle 2 during the switching process, and improving the accuracy and efficiency of the adjustment. The combination of the anti-slip block 22 and the T-shaped cross-section significantly enhances the reliability of the rotation component under dynamic conditions. Even under frequent switching and long-term operation, the system can still maintain a high degree of stability and accuracy, reducing the failure rate caused by mechanical wear or positioning errors.

[0046] As a preferred technical solution of the present invention, the cross section of the slide rod 17 is hexagonal.

[0047] Specifically, the cross-section of the slide rod 17 is designed to be hexagonal, which can ensure that the slide rod 17 can stably drive the mounting plate 3 to rotate and slide, ensuring the accuracy and efficiency of the transmission. At the same time, compared with the 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 present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
