Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid container.

[0002]

2. Description of the Related Art A liquid container is a container for transporting a liquid by a freight car or a truck, and generally has a certain pressure resistance and a predetermined size and capacity. The capacity, there is from about 0.2m ³ to 3m ^3, 1m ³
Is common.

[0003] A liquid container is used when purchasing a small amount of liquid that is not large enough to be received by a tank lorry. In some cases, the entire container is purchased, and the container is returned.

[0004]

Unlike a tank lorry, a liquid container is not always filled with the same liquid. When filling with different liquids, washing is usually performed. Of course, there is a case where cleaning is unnecessary even with different liquids, but cleaning is usually performed.

[0005] Liquid stores and filling stations, where filling a liquid container is a business, have dedicated cleaning equipment. This means that the nozzle automatically enters the small opening and can be moved remotely, making cleaning relatively easy. However, introducing such devices and equipment requires space and expense, and it is impossible in places where the frequency of use is low.

Therefore, such a closed container is washed by inserting a hose or a pipe through the opening and visually cleaning the entire container. However, if it is large to some extent, the inside is dark and cannot be seen in every corner, and it is inaccessible.

Further, in a closed container such as a liquid container, it is desirable that the opening is as small as possible. However, if the opening is small, the above operation becomes more difficult.

[0008] Further, even in the case of cleaning by hand or a simple device, there is a demand for reduction of cleaning waste liquid, reduction of cleaning time, improvement of cleaning accuracy, simplification of cleaning work, and improvement of safety of cleaning work. Is natural. Therefore, in the industry, there has been a long-awaited demand for a liquid container that can be easily washed and that can meet the above demand.

[0009]

In view of the above situation, the present inventor has completed the liquid container of the present invention as a result of intensive studies, and is characterized by a lid for liquid filling. An opening is provided in the container, a pipe in the container is fixed at a position below the opening, a pipe outside the container is provided at an upper position, and a spray nozzle is provided at a tip end of the pipe in the container.

[0010] Here, the lid for liquid filling is a lid provided in the container, and is usually rotatably supported by a hinge at the center position of the upper part and fixed by bolts or screws via packing. Things. Of course, all types may be of a bolting type, a sliding type, or any other type. What is necessary is just to be able to fix the piping mentioned later. Further, when the container of the present invention is a pressure-resistant container, the effect is greater. The degree of pressure resistance is free, but at least 1-2 kg / cm ² G
It should be able to withstand a certain amount of steam. By doing so, steam cleaning can be performed, and the cleaning effect is enhanced.

The opening provided in the lid only needs to allow the cleaning liquid to pass therethrough, and may be a simple hole or a hole provided with a filter or the like. The position of the opening provided may be the center, but in consideration of the easiness of opening and closing the lid, for example, when there is a hinge, the position is free, such as moving closer to the hinge.

The container piping is provided below the opening (inside the container) and is fixed.
The length is determined in consideration of the liquid level, the reach of the cleaning liquid, and the like. Of course, if the tip can be immersed in the filling liquid,
It may be determined only from the cleaning effect. The pipe in the container is usually preferably provided as a straight pipe and provided vertically, but may be inclined to one side when the cleaning effect varies depending on the location depending on the direction of filling and discharging of the liquid and accessories. The piping in the container may be welded to the lid or fixed with bolts or the like. Basically, it is fixed, but it may be detachable.

As the spray nozzle, various commercially available spray nozzles can be used. Further, a nozzle capable of spraying the cleaning liquid onto almost the entire inner wall of the container may be used. For example, it has a spherical shape in which many small holes are provided on almost the entire surface.

Further, one or a plurality of tubes may be provided horizontally from the tip. The above-described spherical nozzle may be provided at the tip of the tube, or a number of small holes may be provided in the tube itself. Further, a spray nozzle of a type that rotates by the pressure of the cleaning liquid may be provided. In short, the spray nozzle may be of any type as long as the cleaning liquid comes out. The spray nozzle is preferably fixed to the piping in the container with a screw or the like.

Since the piping in the container and the spray nozzle are fixed in principle, they must have a length and a shape that do not hinder the opening and closing of the lid.

The outer pipe is provided above the lid and may be a simple nozzle, but is provided with a valve, a plug, a lid and the like so as to be hermetically sealed. This may be any structure such as a structure in which a tap water hose can be easily fitted, a click-type tip, a screw, a flange, and the like. Similarly to the above, this may be welded to the lid or fixed with a bolt or the like.

The above-mentioned inner pipe and outer pipe may be constituted by one (integral type) pipe. That is, it is of a type that penetrates and fixes the opening of the lid.

The cleaning liquid may be any liquid or steam. In the case of simple washing, it seems that there is a lot of water. In such a case, it is only necessary to connect a water supply hose to the pipe outside the container.

Is attached with a screw type. This spray nozzle 7
Is a hollow sphere having a large number of small holes. The small holes are provided on almost the entire surface of the sphere, and the cleaning liquid sprayed therefrom can cover almost the entire inner wall of the container.

Above the lid 2, a pipe 9 outside the container having a valve 8 is provided. In this figure, a water supply hose 10 is fitted to the outer pipe 9 of the container. In this state, when the water supply is opened and the valve 8 is opened, water is sprayed in all directions from the spray nozzle 7 to perform cleaning.

For cleaning, it is only necessary to connect a hose, and no special operation or equipment is required. If it is difficult to remove with water alone, any method such as adding a detergent, using an organic solvent instead of water, or using steam can be used.

FIG. 2 shows details of the spray nozzle 7 used in FIG. In this example, there is a straight pipe section 11 at the top, and a thread is cut inside. A spherical portion 12 is provided at a lower portion, and a large number of small holes 13 are provided. The screw is attached to the piping 4 inside the container.

An experiment was conducted in which the container shown in FIG. 1 (a so-called pressure-resistant liquid container of 1 m ³ ) was used as a photographic developer and then washed. When a low-pressure steam line was connected to the piping outside the container of the container of the present invention, and the steam was sprayed, the cleaning liquid was completed in 100 liters in 7 minutes. To obtain the same level of cleaning effect, 850 liters of cleaning liquid and 15 minutes were required with water and a hose. The work is simpler than manual operation, and the effect is that of a dedicated device.
