Abstract
The invention discloses a leak-free high temperature molten salt pump which comprises a pump spindle (1), a base (2) and a middle adapter (3), wherein the periphery of the pump spindle (1) is provided with an intermediate shaft jacket (4); a liquid separating jacket (5) is arranged outside the pump spindle (1) and in the middle adapter (3); the liquid separating jacket (5) is fixed with a middle bush (6) at the periphery of the intermediate shaft jacket (4) by welding, and is provided with two drain pipes (7) passing through the middle adapter (3); and a nockbush (8) is arranged between the upward side of the base (2) and the pump spindle (1). The structure can avoid molten salt leakage at the pump spindle, and lead the molten salt entering between the intermediate shaft jacket and the middle bush into a molten salt pot from the drain pipes, thus preventing the molten salt leakage from influencing the normal operation and service life of the pump.
Description
Technical field
The present invention relates to a kind of pump, especially relate to a kind of leak-free high temperature molten salt pump.
Background technique
High-temperature melting salt pump is the vertical submerged pump structure, is mainly used in industrial departments such as producing aluminium oxide, melamine, ion film caustic soda, and fed sheet of a media is a high-temperature molten salt, and fused salt is NaNo
37%, NaNO
240% and KNO
353% mixes, and temperature is about 450 ℃.At present; the disclosed a kind of new type high temperature fused salt pump structure of prior art; delivery side of pump promptly only adopts a pipe to connecting with middle adapter between base, can not produce the thermal expansion tension; the unlikely generation eccentric wear of protection liquid lower bearing phenomenon; can prolong the working life of liquid lower bearing, but because discharge tube and middle adapter are shared, pump shaft must pass delivery side of pump; this has just brought new axle envelope problem to pump, promptly can cause the leakage of pump shaft place fused salt.
Summary of the invention
The purpose of this invention is to provide a kind of high-temperature melting salt pump that can stop the fused salt leakage.
The problem that will solve required for the present invention realizes by the following technical solutions: it comprises pump shaft, base and middle adapter, the pump shaft periphery is provided with the jack shaft sheath, be provided with every the liquid cover in the outside of pump shaft, the inside of middle adapter, fixing every the liquid cover with the interstage bushing welding of jack shaft sheath periphery, two liquid-discharging tubes that pass middle adapter are set putting, nockbush is being set above the base and between pump shaft every liquid.
The said structure that the present invention adopts is provided with every the liquid cover in the outside of pump shaft, the inside of middle adapter, can prevent the leakage of pump shaft place fused salt; Put every liquid in middle adapter two outages be set, will introduce the fused salt jar from liquid-discharging tube from the fused salt that enters between jack shaft sheath and the interstage bushing,
Can avoid the normal operation and the working life of fused salt leakage contribution pump.
Description of drawings
The present invention is described further below in conjunction with accompanying drawing:
Accompanying drawing is depicted as structural representation of the present invention
Wherein 1, pump shaft 2, base 3, middle adapter 4, jack shaft sheath 5, every liquid cover 6, interstage bushing 7, liquid-discharging tube 8, nockbush 9, drain pipe
Embodiment
By accompanying drawing as can be known, this leak-free high temperature molten salt pump comprises pump shaft 1, base 2 and middle adapter 3, pump shaft 1 periphery is provided with jack shaft sheath 4, is provided with every liquid cover 5 in the outside of pump shaft 1, the inside of middle adapter 3, contacts the axle envelope problem of bringing with pump shaft to solve high-temperature molten salt; Fixing every liquid cover 5 with interstage bushing 6 welding of jack shaft sheath 4 peripheries, on liquid cover 5, two liquid-discharging tubes 7 that pass middle adapter 3 are being set, above base 2 and 1 of pump shaft nockbush 8 is set.During work, flow through middle adapter 3 and between liquid cover 5 of liquid medium flows out from drain pipe 9.For from entering pump shaft 1 and the fused salt that overlaps 5 gaps every liquid between jack shaft sheath 4 and the interstage bushing 6, can from two liquid-discharging tubes, flow into the fused salt jar.Nockbush 8 is set above base 2, can further stops fused salt and leak.
Claims (1)
1. leak-free high temperature molten salt pump, comprise pump shaft, base and middle adapter, the pump shaft periphery is provided with the jack shaft sheath, it is characterized in that: be provided with every the liquid cover in the outside of pump shaft, the inside of middle adapter, fixing every the liquid cover with the interstage bushing welding of jack shaft sheath periphery, two liquid-discharging tubes that pass middle adapter are set putting, nockbush is being set above the base and between pump shaft every liquid.
