Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high-pressure cleaning device that uses a water jet to clean the outer surface of a contaminated object.

The purpose of the present invention is to clean the outer surface of contaminated objects with a high-pressure water jet.
It is an object of the present invention to provide a cleaning device that can safely, reliably, and easily perform the pollution treatment work.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Reference numeral 1 denotes a contaminant, which has a protruding structure such as a fin 1a over the entire outer peripheral surface and in the axial direction. Reference numeral 2 denotes a cleaning device for the above-mentioned contaminated material 1 according to the present invention, whose main body container 3 has a cylindrical shape with a bottom, and a closing lid 4 is provided at its upper end. Reference numeral 5 designates a cylinder device whose one end is supported by the container bottom 3a, and the other end of which is a rod 6 connected to a contaminant support 7. The cylinder device 5 allows the pollutant 1 placed on the support 7 to move up and down within the container 3 with a stroke approximately equal to its entire length. Reference numeral 8 denotes a guide rod for preventing rotation, one end of which is connected to the lower surface of the support body 7, and the other end of which is slidably held by an engaging member 9 fixed to the main body of the cylinder device 5. guide you up and down. A ring-shaped header 10 is provided at a predetermined location between the outer periphery of the support 7 and the wall of the container 3 and around the entire periphery of the support 7, and is supported by the wall of the container 3 by a bracket 11. As shown in FIG. 2, the entire inner surface of the ring-shaped header 10 has
A large number of nozzles 12 are provided, and the opening directions of the nozzles 12 are directed toward the axis of the support 7, that is, toward the outer surface of the contaminated material 1 placed on the support 7. Furthermore, the ring-shaped header 1
A high-pressure water supply source, such as a high-pressure water pump (not shown), is connected to the pollutant 1 through a supply pipe 13, and high-pressure water is sprayed from a nozzle 12 toward the outer surface of the contaminated object 1 for cleaning. . Reference numeral 14 denotes a drainage basin provided below inside the container 3 and around the entire circumference along the inside of the wall of the container 3, and a treatment device (not shown) outside the container 3.
be led to. Reference numeral 15 denotes a retractable waterproof cylinder whose one end is connected to the lower surface of the support 7 and the other end is connected to the container bottom 3a, and is intended to prevent the washing water of the contaminated material 1 from splashing onto the cylinder device 5. It is. Reference numeral 16 denotes a drainage guiding plate which extends downward from the entire circumferential edge of the support 7 in a tapered manner, and is for guiding the washing water of the pollutants 1 to the drainage basin 14. Note that 17 is an inspection window provided on the wall of the container 3.

Next, a procedure for cleaning contaminated material 1 will be explained. first,
The contaminated material 1 is placed on the support 7 in the lowered position within the container 3 by a crane (not shown). When the contaminated material 1 is placed on the support 7, the closing lid 4 is closed and the inside of the container 3 is completely sealed from the outside. Next, the rod 6 of the cylinder device 5 is slowly extended to raise the contaminant 1. Simultaneously with this rise,
By injecting a high-pressure water jet from the nozzle 12,
The outer surface of the contaminated object 1 is cleaned sequentially from top to bottom. After washing, the washing water is discharged from the drainage guide plate 16.
The water is guided to the drainage basin 14, and is then led to an external treatment device.

As another example, as shown in FIG. 3, the upper half of the container 21 is made into a removable closing lid 22, for example, in order to lower the ceiling height of the building where the cleaning equipment is installed. But that's fine. In the figure, 23 is a viewing window for inspection, and 24 is a closing lid 23.
support bracket, and others are the same as in the previous embodiment. Further, all or part of the containers of the above embodiments may be installed in an underground pit.

As described above, according to the cleaning device of the present invention, the outer surface of the contaminated material is evenly cleaned with a high-pressure water jet inside the closed container, so a very small amount of water can be used to clean the complex surface of the contaminated material. Contaminants can be safely, reliably, and easily cleaned regardless of their external shape. Moreover, the support body on which the contaminated material is placed is supported from below by a cylinder device, and its elevation is guided by a guide rod and an engaging member, so that the contaminated material does not swing or move due to the pressure of the high-pressure water jet. , more even cleaning is possible.
In addition, the cylinder device, guide rod, etc. are covered with an extendable waterproof tube, and the upper part of the waterproof tube, which is easily damaged by direct contact with contaminated water, is protected by a drainage guide plate, so that the cylinder device, etc. will not be contaminated by contaminated water. The waterproof tube will not be corroded.
