Description

Technical Field

[0001] This utility model relates to the field of molten salt technology, specifically to a molten salt pump anti-solidification cutting device. Background Technology

[0002] Molten salt pumps are industrial pumps specifically designed for transporting high-temperature molten salt media. They are widely used in chemical, solar thermal power generation, and other fields. Their pump bodies and impellers are typically made of special alloy materials that are resistant to high temperatures and corrosion, enabling stable operation in high-temperature environments. Molten salt pumps generally feature reliable shaft seals and often employ a combination of mechanical seals and special cooling structures to prevent molten salt leakage. Their flow rate and head can be flexibly adjusted according to actual working conditions to adapt to different production scale requirements. In various industrial processes involving molten salt transportation, they undertake critical media transportation tasks.

[0003] High-temperature molten salt is prone to solidification. If high-temperature molten salt solidifies, the molten salt pump will have difficulty sucking it in and transporting it. The cutting device in traditional molten salt pumps on the market is generally not effective at cutting molten salt, resulting in small pieces of solidified molten salt remaining, which affects the transportation of molten salt. Utility Model Content

[0004] The purpose of this invention is to provide a solidification-preventing cutting device for molten salt pumps, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A solidification-preventing cutting device for a molten salt pump includes a molten salt pump, a first pipe, and a second pipe. The first pipe and the second pipe are connected in an L-shape. The end of the second pipe is connected to the inlet of the molten salt pump. A first dividing mechanism for dividing molten salt material is provided inside the first pipe. An annular seat A is provided inside the first pipe between the first dividing mechanism and the second pipe. A first cutting blade is fixed in an array on the outer peripheral wall of the annular seat A. A driving mechanism is provided on the second pipe and extends into the first pipe to drive the annular seat A to rotate.

[0007] Furthermore, the first dividing mechanism includes a central rod and several first dividing pieces. The central rod is located inside the first pipe and is coaxial with the first pipe. Several first dividing pieces are fixed in a ring array on the outer wall of the central rod. The side of each first dividing piece is fixed to the inner wall of the first pipe. A diversion channel for the flow of molten salt is formed between two adjacent first dividing pieces.

[0008] Furthermore, the drive mechanism includes a mounting base, a drive motor, and a shaft. The drive motor is fixed to the outer wall of the second pipe via the mounting base, the shaft is fixed to the output shaft of the drive motor, and the shaft extends through into the first pipe. The ring seat A is fixedly fitted onto the shaft.

[0009] Furthermore, a ring seat B is also fixedly fitted on the shaft between the ring seat A and the second pipe, and several second cutting blades are fixed in a ring array on the outer peripheral wall of the ring seat B.

[0010] Furthermore, the second cutting blade is arranged in a staggered manner compared to the first cutting blade.

[0011] Furthermore, a second dividing mechanism is provided inside the second pipe, which is used to cut the molten salt material.

[0012] Furthermore, the second dividing mechanism consists of a circular plate, a pair of annular plates, and several third dividing pieces. The circular plate is coaxially arranged inside the second pipe, and the two annular plates are symmetrically arranged on both sides of the circular plate. Several third dividing pieces are fixed in an annular array near the outer edge of both sides of the circular plate. The end of each third dividing piece is fixed to the corresponding annular plate. The outer edge wall of both annular plates is fixed to the inner wall of the second pipe. The diameter of the circular plate is smaller than the diameter of the second pipe, and the diameter of the circular plate is larger than the inner diameter of the annular plate. The circular plate and the two annular plates are coaxially arranged.

[0013] Furthermore, the second pipe end has a flange with several mounting holes.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] This invention provides a first dividing mechanism within a first pipe. The first dividing plates cut the molten salt material, preventing it from solidifying upon entering the first pipe. Simultaneously, the first dividing plates divide the first pipe into several diversion channels, allowing the molten salt material to flow through these channels, thus achieving diversion and ensuring uniform distribution of the molten salt material.

[0016] This invention uses a drive motor to drive the shaft, which in turn drives the first and second cutting blades to rotate. The rotating first and second cutting blades can cut the flowing molten salt material, further preventing the molten salt material from solidifying. In addition, the rotating first and second cutting blades also have a stirring effect. The second cutting blade and the first cutting blade are arranged alternately, which causes turbulence between them, improving the fluidity of the molten salt material and reducing the possibility of solidification.

[0017] This invention, by setting a second dividing mechanism inside the second pipe and using third dividing plates arranged on both sides of the circular plate, can further cut the flowing molten salt material again, thereby improving the anti-coagulation effect of the molten salt material.

Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0025] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] Please see Figures 1-4 The present invention provides a molten salt pump anti-solidification cutting device, including a molten salt pump, a first pipe 1 and a second pipe 2. The molten salt pump adopts the prior art, and its specific structure and working principle are the same as those of the molten salt pump in the prior art. Therefore, it will not be disclosed in this application. The first pipe 1 and the second pipe 2 are connected in an L-shaped structure, and the end of the second pipe 2 is connected to the inlet of the molten salt pump.

[0027] Specifically, the second pipe 2 has a flange 21 at its end, and the flange 21 has several mounting holes 22. The flange 21 is assembled with the flange at the inlet of the molten salt pump. Bolts are inserted into the mounting holes 22 and the holes on the flange, and nuts are tightened to connect the second pipe 2 with the molten salt pump. When the molten salt pump is working, the molten salt material enters from the port of the first pipe 1, flows through the first pipe 1 and the second pipe 2 in sequence, and finally enters the pump body through the inlet of the molten salt pump to realize the pumping of the molten salt material.

[0028] The first pipe 1 is provided with a first dividing mechanism 3 for dividing molten salt material. Specifically, the first dividing mechanism 3 includes a central rod 31 and a number of first dividing pieces 32. The central rod 31 is located inside the first pipe 1 and is coaxial with the first pipe 1. The number of first dividing pieces 32 are fixed in a ring array on the outer wall of the central rod 31. The side of each first dividing piece 32 is fixed to the inner wall of the first pipe 1. A diversion channel 33 for the flow of molten salt material is formed between two adjacent first dividing pieces 32. The cross section of the structure composed of each first dividing piece 32 is in the shape of a star.

[0029] When the molten salt enters the first pipe 1, the first dividing plate 32 is used to cut the molten salt to prevent it from solidifying. At the same time, the first dividing plate 32 is used to divide the first pipe 1 into several diversion channels 33, and the molten salt flows in the diversion channels 33 respectively to achieve diversion of the molten salt and ensure uniform distribution of the molten salt.

[0030] A ring seat A4 is provided inside the first pipe 1 between the first dividing mechanism 3 and the second pipe 2. A first cutting blade 41 is fixed in an array on the outer peripheral wall of the ring seat A4. A driving mechanism 5 is provided on the second pipe 2. The driving mechanism 5 extends into the first pipe 1 and is used to drive the ring seat A4 to rotate. The working of the driving mechanism 5 drives the ring seat A4 and the first cutting blade 41 to rotate. The rotating first cutting blade 41 cuts the molten salt material to further prevent solidification.

[0031] Specifically, the drive mechanism 5 includes a mounting base 51, a drive motor 52, and a shaft 53. The drive motor 52 is fixed to the outer wall of the second pipe 2 via the mounting base 51. The shaft 53 is fixed to the output shaft of the drive motor 52 and extends through into the first pipe 1. The ring seat A4 is fixedly fitted onto the shaft 53. When the drive motor 52 works, its output shaft can drive the shaft 53 to rotate, thereby providing drive for the rotation of the ring seat A4 and the first cutting blade 41.

[0032] Specifically, a ring seat B6 is fixedly fitted on the shaft 53 between the ring seat A4 and the second pipe 2. Several second cutting blades 61 are fixed in a ring array on the outer peripheral wall of the ring seat B6. When the shaft 53 rotates, it can drive the ring seat B6 and the second cutting blades 61 to rotate. The rotating second cutting blades 61 can further cut the molten salt material.

[0033] The second cutting blade 61 is arranged in a staggered manner with the first cutting blade 41.

[0034] The drive motor 52 drives the shaft 53 to rotate the first cutting blade 41 and the second cutting blade 61. The rotating first cutting blade 41 and the second cutting blade 61 can cut the flowing molten salt material respectively, further preventing the molten salt material from solidifying. In addition, the rotating first cutting blade 41 and the second cutting blade 61 also have a stirring effect. The second cutting blade 61 and the first cutting blade 41 are arranged alternately, so that the two stir and create turbulence, which improves the fluidity of the molten salt material and reduces the solidification of the molten salt material.

[0035] Specifically, the second pipe 2 is provided with a second dividing mechanism 7, which is used to cut the molten salt material. The second dividing mechanism 7 consists of a circular plate 72, a pair of annular plates 71, and several third dividing pieces 73. The circular plate 72 is arranged coaxially inside the second pipe 2, and the two annular plates 71 are arranged symmetrically on both sides of the circular plate 72. Several third dividing pieces 73 are fixed in an annular array near the outer edge of both sides of the circular plate 72. The end of each third dividing piece 73 is fixed to the corresponding annular plate 71. The outer edge wall of the two annular plates 71 is fixed to the inner wall of the second pipe 2. The diameter of the circular plate 72 is smaller than the diameter of the second pipe 2, and the diameter of the circular plate 72 is larger than the inner diameter of the annular plate 71. The circular plate 72 and the two annular plates 71 are arranged coaxially.

[0036] When the molten salt flows through the second pipe 2, it first flows through the holes in the upstream annular plate 71, then through the third dividing plate 73 on the upstream side, and then through the third dividing plate 73 on the downstream side. Finally, it flows out through the holes in the annular plate 71 on the downstream side. The third dividing plate 73 arranged on both sides of the circular plate 72 can cut the flowing molten salt again, further improving the anti-solidification effect of the molten salt.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
