In low-temperature pressure container, during through immersed pump transmission cryogenic liquide, be in low-temperature condition during for the work of assurance immersed pump always, present way is the cryopump pond that immersed pump is placed a thermal insulation.On the pump pond body in cryopump pond liquid inlet pipe, muffler are housed; The oral area of fastening flange and pump pond body is welded as a whole, and immersed pump directly is fixed on the blind flange below as pump Chi Gai, and blind flange is connected on the fastening flange through double-screw bolt; Be lined with gasket seal between blind flange and the fastening flange; One through hole is arranged on the blind flange, and drain pipe is directly welded on the blind flange, and cryogenic liquide flows in the drain pipe through this through hole.
Application practice shows that there is following deficiency in present cryopump pond: pump Chi Gai directly contacts with the gas phase of cryogenic liquide, so has directly heat transmission between the two.Because pump pond body is a heat insulation layer, blind flange is exactly a direct heat conduction body like this, and great amount of heat is delivered in the cryogenic liquide, causes the cryogenic liquide saturation pressure to rise, the cap surface large size frosting of pump pond, cryopump pond cisco unity malfunction when serious.
Summary of the invention
The purpose of the utility model is to provide a kind of cryopump pond, directly contacts pump pond cap surface large size frosting that causes even the problem that is difficult to proper functioning with the gas phase of cryogenic liquide with the pump Chi Gai that solves existing cryopump pond.
To achieve these goals; The cryopump pond that the utility model provides comprises pump pond body and the pump Chi Gai that is fixed in said pump pond body oral area; Wherein, In the body of said pump pond, an end of a cylinder is connected in the lower surface of said pump Chi Gai, and the other end of said cylinder is provided with the adpting flange that is used for fixing an immersed pump; Said cylinder or adpting flange are provided with a dividing plate of the gas-phase space that is used to separate said pump pond body; Said dividing plate is provided with second through hole that supplies a drain pipe first through hole that passes and the power line that supplies immersed pump to pass, and said adpting flange is provided with the third through-hole that the drain pipe that supplies immersed pump passes.
According to a kind of preferred implementation in above-mentioned cryopump pond, wherein, said adpting flange is welded in the inwall of said cylinder lower end, and said dividing plate is located at the outer wall of said cylinder.
According to a kind of preferred implementation in above-mentioned cryopump pond, wherein, be provided with the short tube that the end is rounded down vertically in said first through hole and second through hole.
Through setting up cylinder and a dividing plate being set; The utility model is divided into two-part to the gas-phase space in the body of pump pond, whereby, can reduce the gaseous exchange of gas-phase space greatly; Reduce the heat exchange between cryogenic liquide and the blind flange, thereby solve the serious problem of pump pond cap surface frosting.
Description of drawings
Fig. 1 is the sectional structure schematic representation of the utility model preferred embodiment;
The main TV structure schematic representation of the dividing plate of Fig. 2 the utility model preferred embodiment and short tube;
The dividing plate of Fig. 3 the utility model preferred embodiment and the plan structure schematic representation of short tube.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is explained further details.
What need explanation in advance is; In order to describe the annexation of this preferred embodiment and immersed pump; Fig. 1 schematically illustrates the structure of the utility model preferred embodiment and the immersed pump of connection thereof; But the immersed pump 3 among Fig. 1 is not necessary parts of this preferred embodiment, and immersed pump 3 shall not be applied to the protection domain of limit the utility model.
As shown in Figure 1, this preferred embodiment mainly comprises pump pond lid 1 and pump pond body 2, and the oral area of pump pond body 2 is welded with fastening flange 10, and liquid inlet pipe 23, muffler 22 extend into body 2 inside, pump pond.Pump pond lid 1 is a blind flange, and pump pond lid 1 is fixed in fastening flange 10 through double-screw bolt 11, and this pump pond lid 1 is provided with the through hole 13 of blowdown interface 12 and the power line (not shown) through immersed pump 3.In order obviously to reduce the heat exchange between pump pond lid 1 and the cryogenic liquide; In pump pond body 2; The lower surface of pump pond lid 1 connects a cylinder 4, and cylinder 4 lower end mouth are provided with the adpting flange 32 that is used for fixing immersed pump 3, and the lower outside of cylinder 4 is around the dividing plate 6 that is provided with annular.Dividing plate 6 is provided with the through hole (through hole of short tube 2,7 also promptly being set, not shown) that the power line of two drain pipes 21 that supply to be connected in blowdown interface 12 respectively and immersed pump passes.Cylinder 4 has prolonged the distance between immersed pump 3 and the pump pond lid 1; Dividing plate 6 and 32 gaseous exchanges that can effectively reduce gas-phase space of adpting flange; Whereby, this preferred embodiment can reduce the heat exchange between pump pond lid 1 and the cryogenic liquide, avoids the pump pond to cover 1 large size frosting.
Like Fig. 1-shown in Figure 3, in this preferred embodiment, cylinder 4 has the technology of simplification, the advantage that is connected firmly, and the lower surface of pump pond lid 1 is fixed in its upper end, and the lower end is set in the periphery of adpting flange 32.Drain pipe 31 1 ends of immersed pump 3 are fixed on the through hole on the adpting flange 32, and the other end extends pump pond lid 1.In other embodiments; Cylinder 4 can be two semicircular support rings; Also can be a plurality of connecting rods, can adpting flange 32 be fixed in pump pond lid 1 and get final product, so dividing plate 6 must be located at the outer wall of cylinder 4 yet; It also can directly be connected on the adpting flange 32, can be separated to form one and stop the structure of gaseous exchange to get final product.
