Definitions
- the present invention relates to a cleaning liquid used for cleaning an object to be cleaned, a plating liquid, a surface treatment liquid used for cutting or rolling, a surface treatment liquid used for a surface treatment process, and other used surface treatment liquids.
- the present invention relates to a filtration device that removes precipitates that can be precipitated.
- a method is used in which a used surface treatment liquid is transferred using a pump to a sedimentation tank provided separately from the surface treatment tank, the precipitate is precipitated, and the supernatant is reused. It has been.
- the used surface treatment liquid is also reused by filtering it using a filter medium.
- a method of transferring a used surface treatment liquid to a precipitation tank provided separately from a surface treatment tank by using a pump, precipitating the precipitate, and reusing the supernatant is used for the used surface treatment.
- pumps are used to transfer processing liquids, there are restrictions on the pumps that can be used due to the liquid resistance, chemical resistance, heat resistance, etc. of the pumps, and there are restrictions on used surface treatment liquids that can be filtered. Often occurs.
- the size, material, etc. of the particles contained in the used surface treatment liquid As a result, the pump may be damaged or cannot be pumped, and the flow rate is determined by the pump's ability. Therefore, when using a pump, it is difficult to transfer the used surface treatment liquid rapidly.
- the method of reusing a used surface treatment liquid by filtering it with a filter medium causes many problems in that the filter medium is clogged or must be replaced frequently. It was both expensive and uneconomical.
- the present invention is intended to solve the above-described problems, and the surface treatment liquid in the surface treatment tank is rapidly transferred to the pool tank using a reduced pressure state without using a pump, The sediment deposited regardless of the particle size, material, etc. contained in the used surface treatment solution can be transferred rapidly.
- the transferred surface treatment liquid sinks mixed chips, metal powder, and other precipitates in a precipitation liquid tank provided separately from the pool tank, and this precipitation liquid tank and pool By shutting off the communication with the tank by the open / close valve, it is possible to allow only the surface treatment liquid after treatment to flow into the surface treatment tank without affecting the flow caused by the transfer of the surface treatment liquid. It is something to try.
- the present invention is connected to a surface treatment tank that performs surface treatment of an object to be treated with a surface treatment liquid, a pressure reduction mechanism, and the surface treatment tank via a communication control valve.
- a communication control valve When the communication with the surface treatment tank is shut off by closing this communication control valve, the communication control valve is opened after depressurizing the interior to a certain degree of pressure reduction with the pressure reducing mechanism, and the negative pressure is used to open the surface.
- the pool tank may be connected to a mechanism for filling a pressure gas.
- the pool tank and the surface treatment tank may be connected by a transfer pipe capable of transferring the surface treatment liquid between the pool tank and the surface treatment tank.
- the pool tank and the surface treatment tank are connected by a return pipe that transfers the surface treatment liquid from the pool tank to the surface treatment tank, and a transfer pipe that transfers the surface treatment liquid from the surface treatment tank to the pool tank. It may be what you did.
- the return pipe may be provided with a cleaning mechanism for cleaning the surface treatment liquid.
- the used surface treatment liquid can be pooled by connecting the surface treatment tank and the pool tank after the pool tank is decompressed to a certain degree of decompression by the decompression mechanism. It is rapidly transferred into the tank by negative pressure. Since this transfer does not use a pump, the used surface treatment liquid in the surface treatment tank can be rapidly and rapidly moved according to the depressurized state of the pool tank. There are no restrictions on chemical resistance and heat resistance. Further, it is possible to rapidly perform filtration work regardless of the particle size, material, etc. contained in the used surface treatment liquid. In addition, the sediment deposited on the bottom bottom of the surface treatment tank is also introduced into the filtration means together with the used surface treatment liquid, and it is possible to introduce the deposited sediment, which was difficult with a pump. .
- the used surface treatment liquid introduced into the pool tank is mixed into the used surface treatment liquid by opening the open / close valve and communicating the pool tank and the precipitation liquefaction tank. Sediment, metal powder, and other deposits that have fallen into the precipitation liquid tank through the communication nove, and the sediment that has settled in the precipitation liquid tank is communicated with the pool tank by an open / close valve. Since the surface treatment liquid can be returned from the pool tank to the surface treatment tank, the settled sediment rises and flows into the surface treatment tank without being affected by the flow caused by the return. Such a situation does not occur.
- this precipitate may be removed as it is, after the surface treatment liquid is discharged as much as possible, the open / close valve is opened with the deposit accumulated in the precipitation liquid tank, and the pressure reducing mechanism If the inside of the precipitation liquid tank is brought into a negative pressure state through the pool tank, the deposit with the liquid in the precipitation liquefaction tank has been used due to a decrease in boiling point due to reduced pressure. Since the surface treatment liquid volatilizes and is sucked into the pressure reducing mechanism, the precipitate in the precipitation liquefaction tank can be dried. By removing this from the precipitation liquid tank, it can be made into a precipitate without liquid adhesion, and the treatment with little influence on the environment becomes extremely easy.
- FIG. 1 is a cross-sectional view showing a first embodiment of the present invention.
- FIG. 2 is a sectional view showing a second embodiment of the present invention.
- (1) is a surface treatment tank, and is a surface treatment used for cleaning liquid, plating liquid, cutting or rolling used for cleaning an object to be cleaned.
- Liquid (5), surface treatment liquid (5) used in the surface treatment process, and other liquids used for appropriate industrial treatment are stored, and the target surface treatment is performed.
- a pool tank (4) is connected to the surface treatment tank (1) via a transfer pipe (2) and a communication control valve (3), and the surface treatment tank (1) Surface treatment is performed.
- the contaminated surface treatment liquid (5) is collected in the pool tank (4) and can be stored.
- the pool tank (4) is connected to a decompression mechanism (6) such as a vacuum pump so that the inside can be decompressed.
- the pool tank (4) is connected to a pressurized pipe (7) connected to a mechanism (not shown) for filling a pressurized gas so that the pressurized gas can be introduced into the pool tank (4).
- the lower end of the pool tank (4) communicates via a communication pipe (10) provided with an open / close valve (8) to introduce the precipitate (13) in the pool tank (4).
- the precipitation liquid tank (11) is connected.
- the precipitation liquefaction tank (11) is always filled with the surface treatment liquid (5) during the precipitation operation, and the precipitate (13) can be introduced from the pool tank (4).
- an outlet (12) for the precipitate (13) is formed in the precipitation liquid tank (11).
- the pump since the pump is not used, the chemical resistance and heat resistance of the pump to be processed are not restricted.
