Abstract
The utility model discloses a vacuum spraying and de-foaming device. The vacuum spraying and de-foaming device disclosed by the utility model comprises a high pressure vessel, a vacuum vessel and a spraying pipe which can connect the high pressure vessel and the vacuum vessel as a whole. According to the vacuum spraying and de-foaming device disclosed by the utility model, high-viscosity colloid is formed and shaped like thin strips by spraying at high pressure; bubbles existing in the high-viscosity colloid can be automatically exploded; and the de-foaming is carried out in a vacuum environment, so that the de-foaming effect of high-viscosity colloid materials is improved and the production quality and the application processing property of subsequent products are improved.
Description
Technical field
The utility model relates to a kind of vacuum spray defoaming device.
Background technology
Present high viscosity colloid defoaming method mainly contains following several: stir evacuation and centrifugal degassing: utilize the centrifugal force that forms when rotating, utilize the density contrast between bubble and mixture to complete stirring and deaeration; The film deaeration: be provided with the deaeration umbrella in film defoaming device inside, during through the deaeration umbrella cover, under the effect of gravity and viscosity, outwards diffuseed to form the fluid of film-form along umbrella cover when the colloid material, under vacuum action, colloid obtains deaeration and processes.The method mainly is used in low viscous colloid; Vacuum defoamation vacuumizes being equipped with in the vacuum tank of colloid material, and keeps the pressure regular hour, makes bubble rise to liquid level under the effect of pressure reduction, then venting slowly; The vacuum stirring deaeration is stirred under vacuum environment, and it is evenly given vent to anger.
As can be seen from above, the defoaming method of existing defoaming device mainly is applicable to low viscous colloid, and is difficult to separate out for the bubble in full-bodied colloid.
The utility model content
The purpose of this utility model is to provide a kind of vacuum spray defoaming device.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of vacuum spray defoaming device comprises high-pressure bottle, vacuum tank and the shower that high-pressure bottle and vacuum tank are communicated as one.
The colloid of deaeration under the effect of pressure, does not enter vacuum tank by high-pressure bottle through shower and carries out deaeration, reaches the purpose of de-bubble.
In order to improve the efficient of de-bubble, the termination section that described shower is communicated with vacuum tank is provided with shower plate, and shower plate is provided with spray apertures.The aperture of above-mentioned spray apertures is controlled at the diameter greater than colloid minimum unit particle.
In order further to improve the efficient of de-bubble, the cross-sectional area sum of described spray apertures is 1 ~ 1.5 times of shower cross-sectional area.
For the convenient spray of controlling, described shower is provided with the shower valve of controlling spray.
Use the seal head of vacuum container that described vacuum tank comprises the vacuum tank cylindrical shell and is used for the vacuum tank cylindrical shell is sealed for convenient.
In order to reach better sealing effectiveness, be provided with sealing ring between vacuum tank cylindrical shell and seal head of vacuum container.
Use for convenient, described seal head of vacuum container is provided with vacuum-pumping tube and air-outlet valve.
For the convenient vacuum of controlling, also be provided with vacuum meter on described seal head of vacuum container.
Use for convenient, described high-pressure bottle is provided with the high pressure platen, and the high pressure platen is provided with the hydraulic column of connecting fluid pressing system.
Above-mentioned vacuum spray defoaming device by the pressure of regulator solution pressing system, is controlled the spray rate of high viscosity colloid in the deaeration process, regulate the flow that vacuumizes, and controls the discharge rate of gas, thereby detects the vacuum of vacuum meter, realizes the deaeration effect.In order to reach better deaeration effect, must vacuumize while spraying, in order to keep the vacuum of container, be convenient in time discharge the gas in colloid.Must satisfy the vacuum of deaeration technological requirement in the deaeration process, vacuum does not reach the technological requirement of regulation, can reduce the spray rate of high viscosity colloid or change larger flow, vavuum pump that the vacuum limit is higher.
The utility model vacuum spray defoaming device, pass through high-pressure spraying, the high-viscosity glue body is formed fine strip shape, the bubble that is present in the high viscosity colloid pops after by shower plate automatically, carry out deaeration under vacuum environment, improve the deaeration effect of high viscosity colloid material, and then improved the quality of production and the technique for applying performance of postorder product.
