Description

Technical Field

[0001] This utility model relates to the field of molten salt pump technology, specifically a high-temperature resistant molten salt pump. Background Technology

[0002] Molten salt pumps are a type of pump specifically designed for conveying high-temperature molten salt media. They are widely used in chemical, nuclear, electric, and solar thermal power generation fields. The working principle of molten salt pumps is similar to that of ordinary centrifugal pumps or axial flow pumps. They mainly convert mechanical energy into the kinetic and pressure energy of the fluid through the rotation of the impeller, thereby realizing the conveying of molten salt media.

[0003] Currently, since molten salt pumps operate in high-temperature environments, their high-temperature resistance is crucial. However, traditional molten salt pumps only achieve high-temperature resistance through materials, lacking a cooling structure design, which to some extent affects their high-temperature resistance.

[0004] Therefore, a high-temperature resistant molten salt pump is proposed to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1-3 This embodiment provides a high-temperature resistant molten salt pump, including a connecting plate 1. A pump shaft cylinder 2 and a water delivery pipe 5 are respectively installed on both sides of the connecting plate 1. A base plate 3 and a base plate 4 are respectively installed on both sides of the bottom of the connecting plate 1. An oil storage box 41 for oil cooling of the inner wall of the water delivery pipe 5 is installed on the base plate 4. A fan 22 for exhaust cooling of the pump shaft cylinder 2 is installed inside the pump shaft cylinder 2. When the high-temperature resistant molten salt pump is in use, the fan 22 draws in air from the outside and circulates it in the internal cavity of the pump shaft cylinder 2, realizing the effect of heat exchange between the outside air and the inner wall of the pump shaft cylinder 2, thereby improving the high-temperature resistance of the pump shaft cylinder 2. At the same time, the cooling oil in the oil storage box 41 can circulate in the internal cavity of the water delivery pipe 5 to achieve a continuous oil cooling effect, thereby ensuring the high-temperature resistance of the water delivery pipe 5, and thus making the molten salt pump have better high-temperature resistance and extending its service life.

[0025] In this embodiment, as Figure 1 and Figure 2 As shown, a ventilation hole 21 is provided on the outside of the pump shaft cylinder 2, which is connected to the triangular bracket and communicates with the inside of the fan 22 housing. The bottom of the triangular bracket penetrates through the bottom of the outer side of the pump shaft cylinder 2, and the other leg of the triangular bracket is connected to the hollow cavity inside the pump shaft cylinder 2. Therefore, after the fan 22 is started, it can draw outside air into the inner cavity of the pump shaft cylinder 2 for circulation through the ventilation hole 21 and the hole at the bottom of the pump shaft cylinder 2 that communicates with the triangular bracket, thereby achieving the high temperature resistance of the pump shaft cylinder 2.

[0026] In this embodiment, as Figure 1 As shown, a heat dissipation fin 31 is installed on the top of the base plate 3. The top of the heat dissipation fin 31 fits into the hole at the bottom of the pump shaft cylinder 2, so that the temperature of the air discharged or discharged is reduced after passing through the heat dissipation fin 31, thereby improving the heat exchange efficiency.

[0027] In this embodiment, as Figure 2 and Figure 3As shown, two cooling fans 42 are installed vertically on the outer side of the oil storage box 41. An oil pump box 43 is installed at the bottom of one side of the oil storage box 41, and an oil injection pipe is installed on the top of the oil storage box 41. The oil storage box 41 and the oil pump box 43 are connected internally. A return oil pipe 45 is connected to the oil storage box 41. An oil inlet pipe 44 is connected to the outer side of the oil pump box 43. The return oil pipe 45 and the oil inlet pipe 44 are respectively connected to the outer side of the water supply pipe 5. A hollowed-out interlayer is opened inside the pump shaft cylinder 2. The hollowed-out interlayer is connected to the return oil pipe 45 and the oil inlet pipe 44 respectively. Therefore, after the oil inlet pipe 44 injects cooling oil into the hollowed-out interlayer, it flows back to the oil storage box 41 from the return oil pipe 45 when it is full, forming a circulating cooling, thereby ensuring the high temperature resistance of the pump shaft cylinder 2.

[0028] Working principle: When the high-temperature resistant molten salt pump is in use, after the fan 22 is started, it can draw outside air into the inner cavity of the pump shaft cylinder 2 through the ventilation hole 21 and the hole at the bottom of the pump shaft cylinder 2 that connects to the triangular bracket for circulation, thereby achieving the high-temperature resistance of the pump shaft cylinder 2. The heat dissipation fins 31 can reduce the temperature of the air after it passes through the heat dissipation fins 31, thereby improving the heat exchange efficiency. At the same time, the oil pump in the oil pump box 43 injects the cooling oil in the oil storage box 41 into the hollowed-out jacket inside the pump shaft cylinder 2. When the oil inlet pipe 44 injects the cooling oil into the hollowed-out jacket and it is full, it flows back to the oil storage box 41 from the oil return pipe 45, forming a circulating cooling, thereby ensuring the high-temperature resistance of the pump shaft cylinder 2, and thus making the molten salt pump have better high-temperature resistance and extending its service life.

[0029] All technical features in this embodiment can be freely combined according to actual needs. The above embodiment is a preferred implementation of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
