The device makes filtration and dissolution go on in same container, has realized automated control, has saved operating procedure, has avoided the pollution in the transportation process. However, the filter pressing dissolver discharges the solvent mother liquor from the discharge port by introducing saturated steam, and the discharge port is not provided with a related device for intercepting the steam when discharging the solvent mother liquor, so that the steam is inevitably discharged simultaneously when discharging the solvent mother liquor, the saturated steam is wasted, the steam in the tank body is reduced, and the press drying of the residual mother liquor is reduced.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects existing in the prior art, the utility model provides a prevent filter-pressing dissolver trap of steam escape, this trap is different to the density of saturated steam and solvent mother liquor, according to Archimedes' principle, set up the interception hollow ball that can bear buoyancy in the valve body, realized when discharging solvent mother liquor, effectively prevent that saturated steam from discharging simultaneously, reduce the waste of saturated steam on the one hand, on the other hand guarantees that the pressure in the jar body of filter-pressing dissolver is unchangeable, guarantees that the whole of crystal mother liquor is pressed dry; in addition, the steam trap has simple structure and is convenient to manufacture and mold.
In order to achieve the purpose, the utility model discloses the technical scheme who takes:
prevent steam exhaust's filter-pressing dissolver trap, including hollow valve body, valve body from last down set gradually the valve body, hold back the valve body, it is cylindricly to go up the valve body, it is coniform to hold back the valve body, the top of valve body is connected with rather than the communicating feed liquor pipe in inside, the bottom of valve body is equipped with rather than the communicating fluid-discharge tube in inside, this internal hollow ball that is equipped with of valve, the diameter of holding back the hollow ball is greater than the diameter of fluid-discharge tube, just it is made by high temperature resistant corrosion-resistant resistance to compression material to hold back the hollow ball.
Compared with the prior art, the utility model discloses beneficial effect who has:
aiming at the different densities of saturated steam and solvent mother liquor, the trap hollow ball capable of bearing buoyancy is arranged in the valve body according to the Archimedes principle, so that when the solvent mother liquor is discharged, the saturated steam is effectively prevented from being discharged simultaneously, the waste of the saturated steam is reduced, the pressure in a tank body of a filter pressing dissolver is ensured to be unchanged, and the crystal mother liquor is completely dried; in addition, the steam trap has simple structure and is convenient to manufacture and mold.
