Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for selectively and sequentially supplying and discharging various types of fluids through the same channel, and also for easily cleaning the channel. The present invention relates to a fluid supply and dispensing device that is capable of supplying and dispensing fluid.

[Prior art and its problems]

In the past, when various types of fluids were supplied or discharged from one tank to another, the respective pipes were fixedly connected or this was done manually.

For example, if n types of fluids are supplied to m types of tanks, the number of pipes is nXm, and even if there is only one type of fluid, m pipes must be laid, and the construction cost maintenance management 2
There were many things that needed to be improved in crystalloid management.

In addition, in the mobile tank batch production system for high-mix, variable-volume production, the piping on the moving tank loaded on the transport vehicle must be automatically connected to the piping for the various raw materials that require it each time, resulting in time loss. The current situation is that this cannot be taken lightly.

[Problem to be solved by the invention]

In order to solve the above-mentioned problems of the prior art, the present invention selectively supplies and discharges various types of fluids through channels bored in a rotor rotatably disposed within a casing, and The object of the present invention is to provide a fluid supply/discharge device which is provided with a pressing means for bringing the rotor and casing into close contact during the supply/discharge, and is completely leak-free.

[Means to solve the problem]

In order to achieve the above-mentioned object, the fluid supply and dispensing device according to the present invention includes a substantially inverted conical rotor rotatably disposed in a central hole of a casing formed in the same shape as the rotor, and is provided with a vertical passage opening at the center of the bottom surface and a horizontal passage opening at the side communicating with the vertical passage; the rotor is rotated about the vertical passage; A horizontal flow path communicating with the vertical flow path is selectively communicated with a large number of flow paths opened in the casing peripheral wall, and the vertical flow path is connected to a passage opened in the casing to which a fluid discharging pipe is connected. The rotor is characterized in that it is provided with a pressing means that communicates with each other and allows gas or cleaning liquid to be supplied to a flow path formed in the rotor, and that brings the sliding surfaces of the rotor and casing into close contact.

[Effect]

A fluid supply/discharge device according to the present invention includes a substantially inverted conical rotor rotatably disposed in a central hole of a casing formed in the same shape as the rotor, and an opening in the center of the bottom surface of the rotor. A flow path consisting of a vertical flow path and a horizontal flow path opening on a side communicating with the vertical flow path is bored, and the rotor is rotated around the vertical flow path, Since the horizontal flow path is selectively communicated with a large number of flow paths opened in the peripheral wall of the casing, it is possible to sequentially supply or discharge various types of raw materials through the flow paths drilled in the rotor. Furthermore, the supply and dispensing can be performed in the same flow path, and by supplying the cleaning liquid to the above-mentioned flow path, the flow path can be changed after the supply and dispensing of one type of fluid is completed. It is possible to clean the rotor, and since a means for pressing the rotor against the sliding surface of the casing is provided, the flow path and the casing hole are more closely connected, and there is no fear of fluid leakage.
