Abstract
The utility model discloses a high temperature salt melting pump without leakage. The salt melting pump comprises a pump shaft (1), a seat (2), and an intermediate pipe (3). An intermediate shaft protection sheath (4) is provided on the peripheral of the pump shaft (1), a liquid isolation sleeve (5) is provided outside the pump shaft (1) and inside the intermediate pipe (3). The liquid isolation sheath (5) is welded to the intermediate sheath (6) on the periphery of the intermediate shaft protection sheath (4). Two discharging pipes (7) passing through the intermediate pipe (3) are provided on the liquid isolation sheath (5), a flow saving sheath is disposed above the seat (2) below the pump shaft (1). Adopting the structure, the utility model can prevent the leakage of the melted salt at the position of the pump shaft, and the melted salt flowing in between the intermediate shaft protection sheath and the intermediate liner is led into the salt melting tank from the liquid discharging pipe, so that the leakage of the melted salt is prevented from affecting the normal operation and service life of the pump.
Description
Technical field
The utility model relates to a kind of pump, especially relates 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 to base is asked with middle adapter and is connected, and promptly only adopts a pipe, 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 utility model provides a kind of high-temperature melting salt pump that can stop the fused salt leakage.
The problem of the required solution of the utility model 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 utility model 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 are set, will introduce the fused salt jar from liquid-discharging tube, can avoid the normal operation and the working life of fused salt leakage contribution pump from the fused salt that enters between jack shaft sheath and the interstage bushing.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing is depicted as structural representation of the present utility model
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.
