[Detailed description of the invention]

[0001]

The present invention relates to a pipe supporting device for a container , particularly to a liquid injection nozzle of the container.
The present invention relates to a piping support device for a container in which a support member having an annular flange having a diameter larger than the diameter of an injection nozzle portion is fitted, and a pipe in the container is supported by a portion of the support member inside a can .

[0002]

2. Description of the Related Art Conventionally, a vessel such as a reaction can or a tank has to be sprayed with a liquid for cleaning the inside thereof, and for that purpose, a pipe having a squirt nozzle is provided. And
A piping support device for supporting the piping is installed in the inside.

However, reaction cans for chemicals and the like and tanks for storing chemicals are often provided with a glass lining in order to make the inner surface of a metal can body corrosion-resistant, and a complicated supporting device is provided inside the can body. It was difficult to attach.

Therefore, it is necessary to fit a support member having a flange at one end to the liquid injection nozzle, and to support the piping in the container with the support member. That is,
As shown in FIG. 6, a support member 10 composed of a rod member 10a having a flange 13 at one end is fitted to the liquid injection nozzle portion 5 of the container 1, and a mounting device 10 for the support member 10 is provided.
The pipe 6 in the container 1 is supported by b. In addition, a support member 9 made of a tube having a flange-shaped injection part 11 at one end is inserted into the other liquid injection nozzle part 4,
The tip is connected to the pipe 6. Cleaning liquid is tube 1
2, through the flange-shaped injection section, from the tube 9 a of the support member 9 to the pipe 6, and jetted from the jet nozzles 7, 8.

[0005]

However, such a means cannot be adopted in a container which does not have many injection nozzles. This invention has been made to improve a defect in a container that does not have such a large number of liquid injection nozzles, and a state in which a pipe is supported by a support member fitted to the liquid injection nozzle of the container. Then, the liquid injection nozzle part is used for its original purpose,
For example, it is an object of the present invention to provide a pipe support device in a container capable of degassing or liquid injection.

[0006]

In order to achieve the above object, the present invention provides a liquid injection nozzle of a container.
In a piping support device for a container in which a support member having an annular flange having a diameter larger than the diameter of the body injection nozzle portion is fitted and a pipe in the container is supported by a can inner portion of the support member, the support member is connected to the pipe. A pipe having an inner diameter of at least 1.5 times the outer diameter is formed, and a notch parallel to the diameter or a hole penetrating in parallel with the diameter is formed in the pipe, and the notch or the hole accommodates and supports the pipe in the container. Is what you do.

[0007]

The supporting member is a pipe having an inner diameter of at least 1.5 times the outer diameter of the pipe, and a cutout parallel to the diameter or a hole penetrating in parallel with the diameter is formed in the pipe, and the cutout or the hole is formed in the pipe. Since the internal pipe is accommodated and supported, the liquid injection nozzle portion is not blocked by the support member of the pipe. Actions such as injection can be performed. The flange provides a sealing surface that cooperates with the liquid injection nozzle of the container, similar to a conventional support member.

If the auxiliary pipe is fitted into the pipe and the pipe is positioned in the notch, the pipe can be fixed at that position, which is suitable for reliable and long-term support.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to a piping support device in a container shown in the drawings. In the figure,
The same reference numerals indicate the same or corresponding parts.

In FIG. 1, reference numeral 1 denotes a reaction vessel, which is a vessel, which is provided with a stirring blade 2 driven by a motor 3 and further has two nozzles 4 and 5 for liquid injection. The inner surface of the reaction can 1 is glass-lined, and a pipe 6 having spray nozzles 7, 8 is supported by pipe supporting devices 9, 10 inside.

The pipe support device 9 comprises a tube 9a having a flange-shaped injection portion 11 at one end inserted into the injection nozzle portion 4 as in a conventional pipe support device. I have. The cleaning liquid is sent from the pipe 12, passes through the flange-shaped injection part 11, reaches the pipe 6 from the tube 9a of the pipe support device 9, is jetted from the jet nozzles 7, 8, and cleans the inside of the reaction can 1. .

[0012] tube support device 10 is for carrying out this invention, the liquid injection nozzle 5, the liquid injection Bruno
A pipe 14 having, at one end, an annular flange 13 having a diameter larger than the diameter of the chirping part is fitted. The pipe 14 has an outer diameter substantially equal to the inner diameter of the liquid injection nozzle part 5. And
The large-diameter annular flange 13 forms a corresponding surface of the nozzle portion 5 and a liquid or vapor sealing surface.

A notch 15 capable of accommodating the pipe 6 is provided in the inside of the can of the pipe 14 in parallel with the diameter of the pipe. An auxiliary pipe 16 is provided for supporting and fixing the pipe 6 accommodated in the notch 15. The notch 17 of the auxiliary pipe 16 fitted into the pipe 14 fixes the pipe housed in the notch 15.

As shown in FIG. 2, if the inner diameter of the pipe 14 is selected to be larger than the outer diameter of the pipe 6, even if the pipe 14 supports the pipe 6 with its notch 15, the pipe 14 may be blocked. Therefore, gas can be vented or liquid can be injected using the pipe 14. In practice, the ratio of the inner diameter D of the pipe 14 to the outer diameter d of the pipe 6, that is, D / d, is 3/2, that is, 1.5 or more in the case of degassing, in consideration of the strength of the pipe 14 as a supporting member. In liquid injection, 2/1, that is, 2 or more is required. In other words, if a space equal to or more than 1/3 of the inner diameter of the pipe 14 is left, degassing can be effectively performed.

The material of the pipe 14 shown in FIG. 3 and the auxiliary pipe 16 shown in FIG. 4 are both fluororesins, but are made of, for example, corrosion-resistant materials such as polypropylene, polyethylene, titanium, stainless steel, and Hastelloy. You can also.

A pipe 14 'shown in FIG. 5 has a hole 15' through which a pipe 6 can be inserted, which penetrates a diameter portion in place of the notch 15 of the pipe 14 shown in FIG. It has similar functions and effects.

[0017]

According to the invention, the support member fitted to the liquid injection nozzle of the container is a pipe having an inner diameter at least 1.5 times the outer diameter of the pipe, and the pipe has a diameter equal to or larger than the pipe. A notch parallel to the hole or a hole penetrating in parallel is formed, and the notch or hole accommodates and supports the pipe in the container. Alternatively, an operation such as liquid injection can be performed, and this is particularly effective in a container without many liquid injection nozzles. Further, the auxiliary pipe can be fitted into the pipe to secure the pipe, which is suitable for long-term pipe support.
