JPH0492200A - Device for adding multiple kinds of liquid to tank - Google Patents

Abstract

PURPOSE:To suffice with some number of adding nozzle to facilitate increase of adding lines in future by opening adding valves of multiple kinds of liquid in a common supplying pipeline communicated with one nozzle to a tank. CONSTITUTION:In the case that chemical A has foaming property and an addition quantity of chemical B is smaller than that of the chemical A and addition of the chemical B is concluded earlier than the chemical A, size of an outlet of an adding nozzle 5 is made smaller than size of each adding valve to mix the chemical A and the chemical B in the supplying pipeline and conclude addition of the chemical A and the chemical B simultaneously and eliminate contamination of the air and foaming. At this stage, reverse flow of the chemical A and the chemical B to the pipeline is eliminated. Multiple kinds of liquid can be thereby added simultaneously with one adding nozzle.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for adding liquids to a mixing tank, and in particular to an adding device that is effective for adding various types of liquids to a mixing tank in the photographic material manufacturing industry. It is related to.

[Conventional technology]

When adding many types of liquids to one tank, conventionally, adding ports were provided for each type of liquid.

[Problem to be solved by the invention]

Therefore, when adding many types of liquids, many addition ports are arranged on the upper side of the tank, which worsens work efficiency, makes it difficult to add additional addition ports, and obstructs work when cleaning the tank. There were some problems.

The purpose of the present invention is to solve the above-mentioned problems and to enable addition of many types of liquids through as few addition ports as possible, and further,
It is an object of the present invention to provide an apparatus for adding various types of liquids to a tank, which is capable of cleaning each batch or each liquid.

[Means and operations for solving the problems] The above objects of the present invention are as follows: (1) Addition valves for multiple liquids are configured to open into a common supply pipe leading to one addition nozzle to a tank. Features: A device for adding multiple liquids to a tank.

(2) A plurality of liquids according to claim (1), characterized in that the supply pipe is provided with a wash water replenishment valve on the opposite side of the addition nozzle, and the supply pipe is provided with a waste water liquid outlet valve that can be switched with the addition nozzle. Addition device to the tank.

solved by.

The common piping that leads to one addition nozzle of the present invention means that when the addition nozzle is a sanitary valve, the common piping is naturally formed by connecting the attached pipes of each addition nozzle, but when other valves are used In this case, a common pipe is manufactured separately, and the addition valves for various liquids are connected to the common pipe. The addition device configured in this way is
It becomes possible to add many types of liquids through one addition nozzle.

In addition, by providing a cleaning water replenishment valve on the opposite side of the supply pipe to the addition nozzle and a wastewater liquid outlet valve that can be switched with the addition nozzle in the supply pipe, cleaning can be performed for each hatch or each addition valve. be able to implement it.

When adding many types of liquids at the same time in this device, it is recommended that the size of the addition nozzle outlet be smaller than each addition pipe to prevent air from entering the pipes from the addition port, and to prevent other liquids from entering the pipes. It is good to prevent it from entering the addition port.

An embodiment of the present invention will be described with reference to the drawings.

The example in FIG. 1 shows a configuration diagram of an embodiment of an apparatus in which three types of liquids are added through one addition nozzle using sanitary valves. FIG. 2 is a block diagram of an embodiment of the apparatus when cleaning is required in addition to FIG. 1.

To explain the case in which cleaning is required, in Fig. 2, when three types of liquid chemicals are A, B, and C, first when adding chemical A, the cleaning water supply valve 7 and all addition valves are closed. Then, the two-way switching pulp 8 is opened on the addition nozzle side (the wastewater liquid outlet valve is closed), and the chemical A addition valve 1 is opened to add the chemical A into the tank 4 through the addition nozzle 5. After adding chemical A, the addition valve 1 is closed, the two-way switching valve 8 is opened to the waste water outlet side (the addition nozzle side is closed), and the cleaning water replenishment valve 7 is opened.
is opened, and the inside of the common pipe is washed with washing water from the addition valve 1 to the addition valve 2 to the addition valve 3 to the addition nozzle side of the two-way switching valve 8, and the water is drained from the wastewater liquid outlet valve. Drug B,
Chemical C is also added and washed in the same manner.

If washing is not necessary, the washing waste water can be added one after another using the apparatus shown in FIG. 1 without switching (the symbols are the same as those in FIG. 2 described above, so the explanation will be omitted).

In addition, when adding two or more of chemicals A, B, and C at the same time, for example, when adding chemicals A and B at the same time, for example, if chemical A has foaming properties and chemical B If the amount added is smaller than the amount added to the chemical and the addition completes quickly, the addition of chemical A will continue even after adding chemical B, but air will get mixed in from the addition port of chemical B, causing bubbles to form. Become. Therefore, in order to solve this problem, by making the size of the outlet of the addition nozzle 5 smaller than each addition valve, chemicals A and B can be mixed in the supply piping, and chemicals A and B can be added at the same time. Completed, air entrainment and foaming disappear.

Also, at this time, the chemical A will not flow back into the chemical B piping. In this way, many types of liquids can be added simultaneously through one addition nozzle.

In the production of photographic materials, formulations are frequently changed and improved, so it is difficult to predict how many spare nozzles should be arranged. I had to. According to this device, only a few addition nozzles are required, and it is possible to easily accommodate the addition of addition lines in the future.

〔Effect of the invention〕

By using the device for adding multiple liquids to a tank according to the present invention, it is possible to add many types of chemical liquids simultaneously or sequentially from a single addition nozzle. This has been made easier by adding an addition valve without increasing the number of addition ports.
