Abstract
The invention discloses a vacuum spraying defoaming device which comprises a high pressure container, a vacuum container and a spraying pipe communicating the high pressure container and the vacuum container in integral mode. The vacuum spraying defoaming device enables high-viscosity colloid to be processed into slim strip shape through high pressure spraying, bubbles existing in the high-viscosity colloid explode automatically after passing through a spraying plate, and defoaming is conducted under vacuum environment. The vacuum spraying defoaming device improves defoaming effect of high-viscosity colloid materials and further improves production quality and application process performance of follow-up products.
Description
Technical field
The present invention 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 the mixture to finish stirring and deaeration; The film deaeration: be provided with the deaeration umbrella in film defoaming device inside, when colloid material 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, 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, more slowly venting; 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 the full-bodied colloid.
Summary of the invention
The purpose of this invention is to provide a kind of vacuum spray defoaming device.
For solving the problems of the technologies described above, technical scheme of the present invention 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 does not enter vacuum tank by high-pressure bottle through shower and carries out deaeration under the effect of pressure, 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 convenient control spray, described shower is provided with the shower valve of control 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 the 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 convenient control vacuum, also be provided with vacuum meter on the 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 is in the deaeration process, and by the pressure of regulator solution pressing system, the spray rate of control high viscosity colloid is regulated the flow that vacuumizes, the discharge rate of control gas, thus the vacuum of detection 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 the 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.
Vacuum spray defoaming device of the present invention, 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, under vacuum environment, carry out deaeration, 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.
