Abstract
The utility model discloses a negative pressure device used for lost foam casting, which comprises a vacuum distribution device, a vacuum surge tank, a vacuum generator and a vapor-water separation tank; wherein, the outlet of the vacuum surge tank is connected with the vacuum generator by a pipeline, and the outlet of the vacuum generator is connected with the vapor-water separation tank; wherein, the vacuum distribution device is connected with the inlet of a dust removing device by the pipeline, and the outlet of the dust removing device is connected with the vacuum surge tank by the pipeline. The dust removing device is arranged between the vacuum distribution device and the vacuum surge tank, and the gas which is absorbed on a white mould and gasified contains impurities such as dust, smoke and the like, so that the vacuum generator in the device can be kept to work normally. In addition, the negative pressure device has compact structure, easy installation and convenient maintenance, reduces the resistance of the pipeline which is vacuumized, and improves the service efficiency of the device, thus the negative pressure device becomes one of main machine nucleus equipment used for lost foam casting. The negative pressure device has the functions of voltage stabilization, gas filtration, smoke abatement, gas circuit distribution, gas-impurity separation and the like.
Description
Technical field
The utility model relates to a kind of negative pressure device, specifically, relates to a kind of dispellable mould casting negative pressure device.
Background technology
Traditional dispellable mould casting negative pressure device comprises vacuum distribution, the vacuum vacuum tank, the vacuum generator, the carbonated drink knockout drum, vacuum distribution connects the dispellable mould casting sandbox, contain white mould model and molding sand in the sandbox, behind molten steel casting, gas in the sandbox is under vacuum generator dynamic action, pass the vacuum vacuum tank, the vacuum generator, the carbonated drink knockout drum is discharged, gas in the sandbox often contains the molding sand dust, impurity such as smog, in the gas motion process, dust, impurity such as smog tend to stop up the vacuum generator, cause the vacuum generator can not operate as normal.This is the deficiencies in the prior art parts.
The utility model content
Main purpose of the present utility model provides a kind of negative pressure device that contains dedusting tank, adopts dedusting tank to come impurity dirts such as dust, smog in the adsorbed gas, guarantees that the vacuum generator can operate as normal.
The utility model adopts following technical scheme to realize goal of the invention:
A kind of dispellable mould casting negative pressure device, comprise vacuum distribution, vacuum vacuum tank, vacuum generator, carbonated drink knockout drum, described vacuum vacuum tank outlet connects described vacuum generator by pipeline, described vacuum generator outlet connects described carbonated drink knockout drum, wherein, described vacuum distribution connects the dust arrester inlet by pipeline, and described dust arrester outlet connects described vacuum vacuum tank by pipeline.
Preferably, described dust arrester is a dedusting tank.
Compared with prior art, advantage of the present utility model and good effect are: the utility model is provided with dust arrester between vacuum distribution and vacuum vacuum tank, adsorb impurity such as the dust that contains in the gas of white mould model gasification back, smog, vacuum generator operate as normal in the assurance device.In addition, the utility model compact conformation, install easily, easy to maintenance, also reduced the pipe resistance of extracting vacuum simultaneously, improved the service efficiency of equipment, be one of used main frame nucleus equipment of lost foam casting, have functions such as voltage stabilizing, filter vapour, smoke abatement, gas circuit distribution, the assorted separation of gas.
