Abstract

(57) [Abstract] [Purpose] The present invention changes the liquid quality with respect to foam generated on the liquid surface of a tank used for foaming cooling liquid used for machine tools or other general foaming liquid. First, it is an object of the present invention to provide a device in which the effervescent liquid can be used without anxiety, because the device is made compact or the bubbles are broken and gradually defoamed without adversely affecting the environment. [Structure] The vibration type defoaming device of the present invention is a bracket 7 fixed to the cooling liquid tank 1, for example, by floating a trough-shaped container 6 which follows the liquid surface of the tank used for foaming liquid in a constant floating state. A vibration generator 8 is attached to the tub, and this vibration is transmitted to the tub-like container 6 by a plurality of guide bars 5. First, the foam that is in contact with the side wall of the tub-like container 6 is broken by a physical impact. It is characterized by a defoaming device that foams and causes the surrounding foam groups to dance with the waves that are generated at the same time, gradually breaking the bubbles while the foam comrades collide and push each other.

Description

[Detailed description of the device] [0000]     [Industrial applications]   The present invention is applicable to a foaming cooling liquid used for machine tools or other general foaming liquids. Comparing the device without changing the liquid quality against the foam generated on the liquid surface of the used tank Gradual defoaming by blasting or rupturing without adversely affecting the environment Therefore, it is a device that can use the foaming liquid with confidence. [0002]     [Prior art]   As a defoaming method, conventionally, a method of chemically adding an antifoaming agent, or Forced by heating (electric heater) 22 and pump 23 as shown in FIG. The physical methods such as filtration 24, other radiation irradiation, high frequency vibration, spark, etc. Was commonly known. However, either method causes some troubles and eliminates them. I couldn't. [0003]     [Problems to be solved by the device]   In order to improve the workability, the coolant for machine tools is added with increasing permeability. Foams that are mixed with the agent and are generated in general effervescent liquids such as those related to fermentation. Is becoming more and more tougher, and it is becoming more and more difficult to break it. That As a result, a foam layer that floats on the surface of the liquid accumulates and overflows from the tank, causing an obstacle such as soiling the floor surface. Was occurring frequently. Also, unlike the liquid level detection, these foams are also suitable for sensors. There are few things that are expensive, even if there are none, there is no suitable and low cost It is getting harder and harder. Therefore, these defoaming means must first be chemically defoamed. A foaming agent may be considered, but in this case, the liquid will deteriorate and the next physical defoaming will cause There were many problems and problems that did not match the actual situation in terms of strike, space, environment, etc. . [0004]     [Means for Solving the Problems]   The present invention was made to solve the above-mentioned problems, and is used in machine tools. On the liquid surface of the tank used for foaming cooling liquid or other general foaming liquid. Float a basin-shaped container that follows the vertical movement of the liquid surface in a constant floating state, and vibrate on it. It is a vibration type defoaming device that breaks bubbles by giving [0005]     [Work]   If the liquid surface of the cooling liquid tank follows the vertical movement of this liquid surface in a constant floating state, A floating container is floated, and a horizontal vibration is mainly applied to this tub-shaped container with a vibration generator. When given, the foam that is in contact with the side wall and bottom of this tub-like container will be physically impacted. As the bubbles break, the waves generated by the vibration of the tub-like container collide with each other, Or press them together to break the bubbles and gradually eliminate them while repeating this process. [0006]     【Example】   The vibration type defoaming device of the present invention is used for a coolant tank of a machine tool using a coolant. Another embodiment will be described with reference to FIG.   Cooling liquid 2 is stored in the cooling liquid tank 1, and bubbles 4 are generated on the liquid upper surface 3. There is. Then, on this liquid surface, the four guide bars 5 can freely move in the vertical direction and the horizontal direction. Is positioned and the exposed state of the side wall on the liquid surface is uniform at both the minimum and maximum liquid levels. A trough-shaped container 6 is provided which can follow a fixed floating state. This tub container 6, a vibration generator 8 (one example is attached to the bracket 7 fixed to the coolant tank 1). As an air motor for a sander or an electric or electromagnetic vibrator can be applied as ) Is attached, and the vibration from this vibration generator 8 is transmitted through the guide bar 5. The tub-like container 6 is vibrated. [0007]   Then, the foam attached to the side wall of the tub-like container 6 is first broken by physical impact. Bubbles are generated, and then the surrounding bubbles are also drawn to the side wall due to the vibration of the surface tension of each other. It is brought and it is broken. In addition, the waves generated by the vibration of the tub-like container 6 cause bubbles in the surrounding area. The foam group is made to dance, and the foam gradually disappears while repeatedly striking and pushing each other. Be foamed. [0008]     [Effect of device]   According to the vibration type defoaming device of the present invention, the defoaming agent in the defoaming means which has been a problem in the past is removed. Deterioration of liquid quality due to the chemical means used, or heating, filtration, irradiation, high frequency vibration High cost due to physical means such as movement, sparking, expansion of space, or bad environment Machines that use the effervescent liquid because it can gradually defoam without worrying about effects. , It is possible to operate these liquids in general industrial equipment with peace of mind.
