Description

Technical Field

[0001] This utility model relates to the field of molten salt pumps, and more particularly to a high-temperature molten salt pump. Background Technology

[0002] Molten salt pumps, as special pumps for conveying high-temperature, highly corrosive molten salt media, possess high temperature resistance, corrosion resistance, wear resistance, and excellent sealing performance. In many industrial processes, such as solar thermal power generation requiring high-temperature conditions for heat transfer and conversion, and chemical molten salt heating systems operating in chemically corrosive environments, ordinary pumps are often inadequate. High-temperature molten salt pumps, thanks to their special materials and structural design, not only adapt to high-temperature conditions and resist molten salt corrosion, but also efficiently convey molten salt according to process requirements, precisely controlling flow and pressure to ensure stable production operation and product quality.

[0003] High-temperature molten salt pumps are mainly divided into two types: centrifugal and positive displacement. Centrifugal high-temperature molten salt pumps rely on a motor to drive the impeller to rotate at high speed. The molten salt at the center of the impeller is thrown to the outer edge due to centrifugal force, forming a low-pressure zone that draws in new molten salt. After gaining kinetic and pressure energy, the molten salt enters the pump casing. The flow channel expands, reducing the flow velocity. Some of the kinetic energy is converted into pressure energy, and then it is discharged from the outlet. Positive displacement high-temperature molten salt pumps use the working parts inside the pump cylinder and the inner wall of the pump cylinder to form a sealed cavity. The movement of the working parts causes the volume of the cavity to change periodically. When the volume increases, molten salt is drawn in, and when the volume decreases, molten salt is discharged. This process is achieved by the reciprocating piston pump through the reciprocating piston and by the rotation of gears in a gear pump.

[0004] In practical applications of high-temperature molten salt pumps, significant problems have been exposed in the docking process between the equipment and related devices. High-temperature molten salt pumps are often used in industrial processes with extremely high requirements for operating efficiency, such as solar thermal power generation systems and high-temperature chemical reaction devices. However, connecting high-temperature molten salt pumps to these devices often requires extremely complex operating procedures. Operators not only have to repeatedly adjust the angle and position of the pump body, but also need to accurately calibrate the matching degree of the pipe interface. Any slight deviation may lead to poor molten salt delivery, which greatly affects the high-efficiency delivery characteristics that high-temperature molten salt pumps should have, and thus drags down the efficiency of the entire production process. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-temperature molten salt pump, which aims to improve the problem of requiring complex operations to align the equipment and devices during use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-temperature molten salt pump, comprising a connecting plate, a plurality of fixing columns fixedly connected to the top of the connecting plate, each fixing column having a fixing groove on its outer wall, a support plate slidably connected to the top of the connecting plate, a plurality of connecting grooves on the bottom of the support plate, a plurality of fixing components disposed inside the support plate, a drive motor fixedly connected to the top of the support plate, an inlet / outlet liquid assembly disposed on the outer wall of the drive motor, an impeller box fixedly connected to the bottom of the drive motor, an inlet pipe fixedly connected to the bottom of the impeller box, and an outlet pipe fixedly connected to the outer wall of the impeller box;

[0007] Each of the fixing components includes a soft rubber ring and a spring. The outer wall of each soft rubber ring is slidably connected to the inside of the support plate. Each spring is disposed inside the support plate. One end of each spring is fixedly connected to the inside of the support plate, and the other end of each spring is fixedly connected to the outer wall of the soft rubber ring.

[0008] As a further description of the above technical solution:

[0009] The liquid inlet / outlet assembly includes an inlet pipe and an outlet pipe. One end of the inlet pipe is fixedly connected to the outer wall of the drive unit, and one end of the outlet pipe is fixedly connected to the outer wall of the drive unit. The inlet pipe and the outlet pipe are arranged in a parallel array and fixedly connected to the outer wall of the drive unit.

[0010] As a further description of the above technical solution:

[0011] A flange is fixedly connected to the top of the liquid outlet pipe, and multiple bolts are fixedly connected inside the flange.

[0012] As a further description of the above technical solution:

[0013] A liquid guide pipe is fixedly connected to the top of the flange, and a retaining ring is slidably connected to the outer wall of the flange.

[0014] As a further description of the above technical solution:

[0015] A fixing block is fixedly connected to the outer wall of the fixing ring, and a connecting block is fixedly connected to the outer wall of the fixing ring.

[0016] As a further description of the above technical solution:

[0017] One end of the connecting block is rotatably connected to a rotating shaft, and the outer wall of the rotating shaft is rotatably connected to a connecting block.

[0018] As a further description of the above technical solution:

[0019] One end of the connecting block two is fixedly connected to a fixing ring two, and a rotating block is fixedly connected to the outer wall of the fixing ring two.

[0020] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the operator first lifts the equipment, then moves it above the connecting plate, aligns the connecting groove with the fixing column, and then lowers the equipment so that the fixing column enters the connecting groove. Under the pressure of the outer wall of the fixing column, the soft rubber ring retracts into the support plate. When the fixing column enters the innermost part of the connecting groove, the soft rubber ring pops out under the action of the spring to fix the connecting plate and the support plate. This achieves the effect of easily aligning the equipment with the device to be used during the use of the equipment, avoiding the problem of complicated operation required to align the equipment with the device during the use of the equipment, thereby improving the efficiency of the high-temperature molten salt pump.

[0024] 2. In this utility model, the outlet pipe and the guide pipe are first connected together with bolts. Then, the inner wall of the first fixing ring is fitted to the outer wall of the flange. Next, the rotating block is held to fit the inner wall of the second fixing ring to the outer wall of the flange. Then, the threaded post is rotated into the inside of the fixing block, and then the nut is rotated onto the threaded post, thereby fixing the first fixing ring and the second fixing ring together. This achieves the effect of sealing the outer wall of the flange during equipment use to prevent leakage of internal liquid, avoiding the problem that leakage of internal liquid during equipment use can easily cause harm to surrounding equipment and operators, thus improving the safety of the high-temperature molten salt pump.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 The present invention provides an embodiment of a high-temperature molten salt pump, comprising a connecting plate 1, a plurality of fixing columns 2 fixedly connected to the top of the connecting plate 1 for connecting the connecting plate 1 to a support plate 4, each fixing column 2 having a fixing groove 3 on its outer wall for accommodating a soft rubber ring 6, a support plate 4 slidably connected to the top of the connecting plate 1 for supporting the equipment, a plurality of connecting grooves 5 on the bottom of the support plate 4 for accommodating the fixing columns 2, a plurality of fixing components inside the support plate 4 for fixing the connecting plate 1 and the support plate 4, a drive motor 8 fixedly connected to the top of the support plate 4 for driving the equipment, an inlet and outlet liquid assembly on the outer wall of the drive motor 8 for guiding the coolant, an impeller box 11 fixedly connected to the bottom of the drive motor 8 for accommodating the impeller and the shaft, an inlet pipe 12 fixedly connected to the bottom of the impeller box 11 for introducing the brine, and an outlet pipe 13 fixedly connected to the outer wall of the impeller box 11 for discharging the brine.

[0033] Each fixing component includes a soft rubber ring 6 and a spring 7. The outer wall of each soft rubber ring 6 is slidably connected to the inside of the support plate 4. The soft rubber ring 6 is made of deformable soft rubber and can connect the fixing post 2 inside. Each spring 7 is set inside the support plate 4 to provide elastic force for the soft rubber ring 6. One end of each spring 7 is fixedly connected to the inside of the support plate 4, and the other end of each spring 7 is fixedly connected to the outer wall of the soft rubber ring 6. The liquid inlet and outlet assembly includes a water inlet pipe 9 and a water outlet pipe 10. One end of the water inlet pipe 9 is fixedly connected to the outer wall of the drive motor 8 for introducing coolant, and one end of the water outlet pipe 10 is fixedly connected to the outer wall of the drive motor 8 for discharging coolant. The water inlet pipe 9 and the water outlet pipe 10 are arranged in a parallel array and fixedly connected to the outer wall of the drive motor 8.

[0034] Specifically, when the high-temperature molten salt pump needs to be installed, the operator controls the lifting equipment to lift the equipment and slowly move it towards the top of the connecting plate 1. After the equipment is moved to the approximate position, the operator gradually aligns the connecting groove 5 with the fixing column 2, and slowly lowers the equipment. The fixing column 2 begins to slowly enter the interior of the connecting groove 5. As the fixing column 2 goes deeper, under the strong pressure of its outer wall, the soft rubber ring 6 slowly retracts into the interior of the support plate 4. When the fixing column 2 finally enters the innermost part of the connecting groove 5, the soft rubber ring 6, under the strong elastic force of the spring 7, tightly fixes the connecting plate 1 and the support plate 4 together. At this point, the docking work between the equipment and the device is completed.

[0035] Reference Figure 4 A flange 14 is fixedly connected to the top of the outlet pipe 13 to fix the outlet pipe 13 and the guide pipe 16. Multiple bolts 15 are fixedly connected inside the flange 14 to connect the outlet pipe 13 and the guide pipe 16. The guide pipe 16 is fixedly connected to the top of the flange 14 for discharging the brine solution. A retaining ring 17 is slidably connected to the outer wall of the flange 14 to prevent brine splashing. A retaining block 18 is fixedly connected to the outer wall of the retaining ring 17 to connect the retaining ring 17 and the retaining ring 22. A connecting block 19 is fixedly connected to the outer wall of the retaining ring 17 to connect the retaining ring 17. 19 is rotatably connected to a rotating shaft 20 for rotating fixed ring 17 and fixed ring 22. A connecting block 21 is rotatably connected to the outer wall of the rotating shaft 20 for connecting fixed ring 22. Fixed ring 22 is fixedly connected to one end of the connecting block 21 to prevent salt splashing. A rotating block 23 is fixedly connected to the outer wall of fixed ring 22 for connecting threaded post 24. Threaded post 24 is rotatably connected inside the rotating block 23 for connecting fixed ring 17 and fixed ring 22. A nut 25 is threadedly connected to the outer wall of the threaded post 24 for locking fixed ring 17 and fixed ring 22.

[0036] Specifically, after the main body of the equipment is installed, firstly, the staff inserts the bolts 15 one by one into the corresponding screw holes and tightens each bolt 15 to ensure a firm connection between the liquid outlet pipe 13 and the liquid guide pipe 16. Next, the staff picks up the fixing ring 17 and brings it close to the flange 14, so that the inner wall of the fixing ring 17 fits against the outer wall of the flange 14. At this time, the staff holds the rotating block 23 and rotates it, so that the fixing ring 22 slowly approaches the flange 14, and the inner wall of the fixing ring 22 also fits against the outer wall of the flange 14. Then, the staff rotates the threaded post 24 into the fixing block 18. When the threaded post 24 has entered the fixing block 18 to a sufficient depth, the staff picks up the nut 25, puts it on the threaded post 24, and then starts to rotate the nut 25. Finally, the fixing ring 17 and the fixing ring 22 are firmly fixed together. Thus, the protective installation of the equipment is successfully completed.

[0037] Working principle: During the use of the high-temperature molten salt pump, the operator first lifts the equipment and moves it above the connecting plate 1, aligns the connecting groove 5 with the fixing column 2, and then lowers the equipment so that the fixing column 2 enters the connecting groove 5. Under the pressure of the outer wall of the fixing column 2, the soft rubber ring 6 retracts into the support plate 4. When the fixing column 2 enters the innermost part of the connecting groove 5, the soft rubber ring 6 pops out under the action of the spring 7 to fix the connecting plate 1 and the support plate 4, thus completing the alignment of the equipment and device. After the equipment is installed, the liquid outlet pipe 13 and the liquid guide pipe 16 are connected together with bolts 15. Then, the inner wall of the fixing ring 17 is attached to the outer wall of the flange 14. Then, the rotating block 23 is held to attach the inner wall of the fixing ring 22 to the outer wall of the flange 14. Then, the threaded column 24 is rotated into the fixing block 18. Then, the nut 25 is rotated onto the threaded column 24, thereby fixing the fixing ring 17 and the fixing ring 22 together, thus completing the protective installation of the equipment.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
