Abstract

PURPOSE:To contrive the cleaning of the inside of a large-size tank in a short time by a method wherein a ring is formed in the tank by connecting ring- forming members together via a connecting member and the scrubbing members provided on the ring-forming members are made to move slidably in contact with the inner peripheral surface of the tank. CONSTITUTION:Ring-forming members 1 composed of at least of one of a flexible tubular body, rod body and plate body are introduced into a tank 80 from a tank opening part 82. In this tank 80, a ring A having a slightly smaller diameter than the inside diameter of the tank is formed by connecting the members 1 together via a connecting member 5a. Scrubbing members 3 prefixed to the member 1 or detachably attached to the outer peripheral surface of the ring A are brought into contact with the inner peripheral surface of the tank and the ring A is then slidably moved in the tank 80 along the inner peripheral surface thereof. As a result, there is no need for the worker to enter the tank for cleaning thereof and the inside of a large-size tank can also be cleaned in a short time.

PRIOR ART This type of tank often has a diameter of 5 m or more and a height of 10 m or more. Conventionally, when cleaning the inside of such a large tank, the side wall surface of the large tank 80 in FIG. An operator enters the tank through an opening 82 provided at the bottom of the tank 81 and can freely open and close it.
Alternatively, by bringing a ladder 84 or stepladder into the tank through the injection port 83 provided at the top of the tank,
Lean it against the tank's inner wall, hold onto the ladder with one hand, and hold the long-handled brush with the other.
Methods such as rubbing the wall surface are used.

Brush work is generally done while spraying cleaning liquid such as water or detergent onto the tank's inner wall.
A fluid supply hose is attached to the handle of the brush, and it is difficult to operate the brush with this heavy hose on a ladder, which not only prevents sufficient cleaning, but also causes severe fatigue. However, working while moving a ladder was inefficient, and had the disadvantage that it took several days to complete the cleaning work of the tank. Furthermore, depending on the stored items, the working environment may be poor due to the generation of foul odors and harmful gases.
It had a number of drawbacks, including the fact that it may not be possible to maintain long hours of work inside the tank.

Structure of the Invention The gist of the present invention is to provide a tubular body, a rod-shaped body, a plate-shaped body made of a flexible material such as plastic, a composite material of plastic and carbon fiber, glass fiber, etc. , with the necessary members added as a unit material, the both ends of which are connected in a ring shape by connecting members according to the shape of each end, so that a ring can be formed, and these ring forming members is first carried into the tank through the opening of the large tank, and then, in the tank, if there is only one ring forming member, one connecting member (or one set) that connects both ends of the ring forming member is installed.
If the ring forming member is composed of three pieces, three (or three sets) of connecting members are used to form a ring having a diameter slightly smaller than the inner diameter of the tank. A wiping member such as a brush or felt may be attached to this ring forming member in advance, or a wire or rod may be placed inside the tank and protruded from the outer periphery of the ring, and the ring may be suspended from the top opening of the tank. The ring can be suspended from a suspension support and moved up and down in the tank, or the ring can be coupled to a rotating shaft provided at the center of the ring and rotated, or the ring can be attached to a The present invention provides a method and an apparatus for cleaning the inside of a tank by bringing the wiping member into sliding contact with the inner circumferential surface of the tank by a method such as rotation by the jet thrust of a cleaning liquid injection nozzle provided therein. Examples of the rotary shaft placed at the center of the ring include the output shaft of a motor held by a suspension support suspended from the tank opening 11, and a flexible shaft suspended from the tank opening 1. I can do it. The ring is equipped with rollers that can be moved horizontally around the inner circumferential surface of the tank to prevent the wiping member from being pushed excessively against the inner wall of the tank and to encourage rotation of the ring. may be provided. As a means for positioning the rotating shaft to the center of the tank, a motor or
From the bearing of the rotating shaft, equal length 1 d in the horizontal direction
A faster method is to have a protruding arm and a rolling element installed at the tip of the arm in a telescoping annex a short distance in the arm's extension direction. The ring can be slid in the vertical direction by lowering the ring and its attachments by their own weight, and if the ring is to be raised, the suspension wire can be wound up using a winch or the like, or
Various methods can be adopted, such as a method in which a weight is provided at the center of gravity of the ring and the ring is lowered, or a bow string is used to pull the ring downward. Hereinafter, the method of the present invention will be described in detail along with preferred embodiments of the apparatus used in the method of the present invention.

A cleaning liquid spray nozzle (not shown) is open. 7a
is a hose connected to the liquid spray pipe 7 to forcefully feed cleaning water such as water or detergent solution, and is connected to a pump P outside the tank 80. The liquid dispersion pipe also has the role of a weight to allow the ring A to fall freely against the sliding resistance with the inner peripheral surface of the tank, so its diameter depends on the material of which the ring A is made. Selected appropriately. As shown in FIG. 2, the brush 3 has bristles 11 planted on a hard rubber plate 10 on the outer peripheral surface 1a of the ring A, and is attached to the ring A using a fastening band 12 integrated with the rubber plate 10.
It is provided on the outer circumferential surface of the ring by a method such as fixing the rubber plate to the ring forming member 1 or integrating the rubber plate and the ring forming member 1 by adhesion in advance. In this way, within the tank 80,
After assembling the cleaning device, the operator goes outside the tank, rotates the electric winch 5 forward and backward, and at the same time operates the pump P to spray cleaning liquid onto the tank's inner circumferential surface, thereby cleaning the tank's inner surface. Dirt is removed by the brush and flows out of the tank from the lower opening along with the cleaning liquid.
