Abstract

PURPOSE: To provide a device which is capable of defoaming the foam of various liquid substances efficiently and further defoaming continuously by applying a centrifugal force in a multiplex fashion. CONSTITUTION: Multiple rotary cylinders 1 which apply a centrifugal force to a liquid are arranged, and a ring-like part 2 to hinder the scattering of the liquid is provided above the rotary cylinders 1. Thus, the scattering liquid substance is once received, so that the substance is centrifugally defoamed sequentially in multistages.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the production of various liquid industrial materials, foodstuffs and chemicals, and their use.
The present invention relates to a multi-stage centrifugal defoaming device capable of efficiently removing bubbles.

[0002]

2. Description of the Related Art Conventionally, for defoaming a liquid substance, there have been devices such as rotating at high speed in a container to separate bubbles on the principle of centrifugal separation, or ejecting the liquid in a vacuum. However, because there are various performance problems such as not being able to remove fine bubbles,
In the end, generally, a method is adopted in which the object is finally reached only by leaving it in a vacuum for a long time.

[0003]

DISCLOSURE OF THE INVENTION The present invention is an apparatus capable of efficiently defoaming fine bubbles in various liquid substances by continuously exerting centrifugal separation forces, and also capable of continuous defoaming. Is provided.

[0004]

According to the present invention, first, the rotary cylinders 1 for exerting a centrifugal force on a liquid are arranged in multiple layers. Even if the liquid is rotated as it is, after the liquid is scattered from the central rotary cylinder 1, only the upper part of the rotary cylinder 1 is scratched one after another, and the centrifugal force does not work effectively except in the central rotary cylinder 1.
Therefore, a ring-shaped scattering obstruction component 2 is arranged on the upper part of each rotary cylinder 1, and once it receives the scattering liquid substance, it is a device for centrifugal defoaming one after another in multiple layers.

[0005]

By the above-mentioned means, the liquid substance is subjected to centrifugal force in the rotary cylinder 1, and the bubbles and the liquid are centrifugally separated due to the difference in specific gravity, and this effect is performed one after another for the number of layers of the rotary cylinder 1.

[0006]

In the first embodiment shown in FIG. 1, there is a three-layer rotary cylinder 1 and a ring-shaped scattering obstruction member 2 in the upper part in the middle thereof. Furthermore, the scattering obstruction component 2 is provided with a defoaming gas passage 3 that serves as an escape path for degassed gas, and an inlet 4 for injecting a liquid substance.

In the second embodiment shown in FIG. 2, the scattering obstruction parts 2 are integrated with the upper part of the rotary cylinder 1 every other one in the shape of an inward edge. The liquid substance that has received the centrifugal force moves to the next rotary cylinder 1 from the communication port 5 provided in the lower part of the rotary cylinder 1 with the scattering obstruction parts 2.

If any of the embodiments is constructed in a vacuumed container, the vacuum defoaming synergistically acts on the centrifugal separation, and a very high defoaming effect can be achieved. Further, if the defoamed liquid is continuously collected while continuously introducing the liquid substance from the inlet 4, it is possible to incorporate the liquid substance into a production line or the like and continuously operate.

[0009]

INDUSTRIAL APPLICABILITY According to the present invention, the centrifugal separation force effectively works in a multiple manner and can be combined with vacuum defoaming, so that the defoaming effect is high in a very wide range of application and can be continuously performed. Automatic continuous operation is also possible in the line for producing and using liquid substances. Therefore, it not only makes the conventional defoaming more efficient, but also contributes greatly to the development of the chemical industry, the pharmaceutical industry, the food manufacturing, the electronics field and the like.
