Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to cleaning equipment for removing contaminants adhering to internal structures of pumps, etc.

[Conventional technology]

Conventionally, in this type of cleaning equipment, as shown in FIG. 8, a spray pipe 31 having a spray nozzle 32 is attached to the upper part of a cleaning tank 30, and a column 33 and a spray pipe 31 are installed to prevent the cleaning liquid from scattering to the outside.
The outer periphery of was covered with poly sheet 34.

Further, as shown in FIG. 9, a cylindrical cover 35 made of a rigid material was sometimes provided above the cleaning tank 30.

[Problem that the invention attempts to solve]

These conventional facilities have a problem in that they require as much space for transportation and storage as they do for use.

[Means for solving problems]

The lower half of the cleaning tank is an outer cylinder with a bottom, and the upper half is an inner cylinder with a smaller diameter than the lower half, making it a telescopic structure that can be moved downward.

Furthermore, by separating the upper half of the cage-like spray tube installed inside the cleaning tank from the lower half, or by using a flexible rubber tube for the lower half, the upper half can be removed. The structure allows the part to be moved downward.

[Effect]

Since the cleaning tank has a telescopic structure, it can be stored in the upper and lower halves of the tank, and the volume occupied by the tank during transportation and storage is halved.

In addition, by moving the upper half of the cage-like spray tube downward, it can be stored in the lower half of the cleaning tank along with the lower half, reducing the overall volume occupied by the equipment by half, making it convenient for transportation and storage. Can be used as a compact cleaning tank.

〔Example〕

FIG. 1 shows an embodiment of the present invention in use. The cleaning tank includes an outer cylinder 3 with a bottom forming the lower half thereof,
Inner cylinder 2, which has a smaller diameter and forms the upper half of the tank
The inner cylinder 2 has a telescopic structure that allows it to move downward when not in use. When in use, the cylinder 2 is connected to the upper part of the bottomed outer cylinder 3 via the connecting part 4, as shown in the figure.

The upper half of the spray tube 12 is connected to its upper header 1.
The spray tube lower half 13 is held inside the inner cylinder by a spray header support 15 that supports 0, and is connected to the lower header 11 provided in the bottomed outer cylinder 3 through a coupling 16. They are connected to form a cage. When not in use, the upper half 12 can be separated from the lower half 13 and moved downward.

The spray pipe has a spray nozzle 14 opening inward of the tank, and sprays cleaning liquid supplied from the outside via the lower header 11 onto the object 1 to be cleaned suspended within the tank.

In this embodiment, the outer cylinder 3 is provided with a heater 18 for heating the cleaning liquid to prevent the temperature of the cleaning liquid from decreasing.
7 is attached to improve heat retention.

A thermometer 19 and a liquid level gauge 20 are attached to the outer cylinder 3 to maintain the temperature and liquid level (WL) of the cleaning liquid at appropriate values. A photoelectric switch 21 is attached to the inner cylinder 2 to assist in correct positioning when suspending the object to be cleaned in the tank.

FIG. 2 shows the reduced state of this embodiment during transportation and storage. When not in use, the cleaning tank is separated into upper and lower parts at the connection part, and the inner cylinder 2 is housed in the outer cylinder 3 with a bottom.

The spray tube is also separated into upper and lower parts, and the upper half 12 and lower half 13 are housed together with the inner cylinder 2 in the outer cylinder 3 with a bottom. In the figure, only the lower half 13 of the spray tube is shown, and the upper half is omitted.

FIG. 3 is a perspective view of the spray pipe assembled into a cage shape in FIG. 1 of this embodiment. a spray tube upper half 12 connected to the upper header 10;
The lower half 13 of the spray tube connected to the lower header 11 forms an integral cage-like spray tube via a coupling 16.

FIG. 4 is a perspective view showing the spray tube during transportation and storage in FIG. 2 of this embodiment. The spray tube is separated into an upper half 12 and a lower half 13, and the upper half is inserted between the lower halves while maintaining a positional relationship that does not interfere with each other, thereby reducing the storage volume.

FIG. 5 is a plan view showing the positional relationship of the stoppers in a state where the inner tube 2 is connected to the outer tube 3 when the cleaning tank is used. This shows that the outer cylinder stopper 6 is in a positional relationship to support the inner cylinder stopper 5 in the vertical direction. The positioning stopper 8 is brought into contact with the outer cylinder stopper 6, and this is used to easily find the proper mutual positional relationship between the outer cylinder stopper 6 and the inner cylinder stopper 5. A reinforcing plate 7 is attached to the missing part of the inner cylinder stopper 5 to maintain strength.

FIG. 6 is a plan view showing the positional relationship of the stoppers when the inner cylinder 2 is housed in the outer cylinder 3. This shows that the outer cylinder stopper 6 is not in a positional relationship that supports the inner cylinder stopper 5 in the vertical direction.

FIG. 7 is a side view of the connecting part between the inner cylinder 2 and the outer cylinder 3 when the cleaning tank of this embodiment is used, and shows a state in which the inner cylinder stopper 5, the outer cylinder stopper 6, and the positioning stopper 8 are in contact with each other. Indicates positional relationship. Furthermore, the insertion position of the urethane sealing material 9 to prevent external leakage of the cleaning liquid is also shown.

As is clear from the above explanation, the cleaning tank and the cage-like spray pipe installed inside it during transportation and storage have a structure that can be separated vertically, and the upper half of the tank and the upper half of the cage-like spray pipe By moving both of them downward, the total occupied volume can be halved.

In the above embodiment, the spray pipe is divided into an upper half and a lower half, which are connected with a coupling ring when in use, and separated when not in use. The lower half of the spray tube can be made of a flexible or rubber tube, and the upper half of the cage-like spray tube can be moved downward without separating the upper and lower parts when not in use. It may be a structure.

[Effect of idea]

The lower half of the cleaning tank is an outer cylinder with a bottom, and the upper half has a telescopic structure with an inner cylinder that is smaller in diameter and can move downwards, and a ring-shaped header is provided at the bottom of the outer cylinder with a bottom. By having a structure in which the upper half of the cage-like spray tube connected to can be moved downward, sufficient cleaning tank volume and cleaning function can be obtained when the cleaning equipment is in use, and the overall occupied volume can be halved when not in use. By the way,
It has the effect of saving space for transportation and storage.
