In order to solve this problem, the present invention provides that a casing into which the objects to be cleaned are carried in and out by a chain conveyor has an opening wide enough to accommodate the objects to be cleaned, and a plurality of casings along the peripheral wall. It is formed by an inner cylinder part of a predetermined length in which through-holes are bored, and an outer cylinder part integrally arranged outside the inner cylinder part with arbitrary intervals so as to cover each of the through-holes. In the cleaning device, the chain conveyor is disposed outside the casing along the casing, and a hollow portion is formed between the outer cylindrical portion and the inner cylindrical portion, into which cleaning liquid is supplied under pressure. A plate-shaped mounting table is attached to the conveyance chain of the chain conveyor, and the object to be cleaned is placed thereon, and the plate-shaped mounting table passes through the inner cylinder part.The casing has a strip for inserting and guiding the mounting table in parallel with the conveyance path of the chain conveyor. It is characterized by having a slit formed therein.

[Effect]

According to the present invention, since the chain conveyor that carries the items to be cleaned into and out of the casing is disposed outside the casing, the durability of the chain conveyor is increased, and at the same time, the maintenance and inspection work of the chain conveyor is improved. becomes extremely easy.

In addition, it is sufficient that the inner cylindrical portion of the casing has an opening wide enough to allow a plate-shaped mounting table attached to the conveyance chain of the chain conveyor and the object to be cleaned placed on the mounting table to pass through. Therefore, the entire cleaning device can be significantly downsized.

〔Example〕

Embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is a cross-sectional view showing an example of a cleaning device according to the present invention, and FIG. 2 is a vertical cross-sectional view thereof.

The cleaning device shown in this example has a large number of through holes 2 at predetermined intervals along the peripheral wall of a substantially cylindrical inner cylinder portion 1 having an opening diameter sufficient to accommodate an object W to be cleaned such as a shaft. , 2... are bored, and a substantially cylindrical outer cylinder part 3 is integrally arranged at a constant interval on the outside of the inner cylinder part 1 so as to cover each through hole 2, 2... A casing 4 is formed.

The outer cylinder part 3 is selected to have the same length as the inner cylinder part 1 or shorter than this, and is arranged concentrically with the inner cylinder part 1, so that there is no space between the outer cylinder part 3 and the inner cylinder part 1. A hollow portion 5 is formed therein.

Further, a cleaning liquid supply pipe 6 for supplying cleaning liquid under pressure into the hollow portion 5 is connected to the outer cylinder portion 3 .

In addition, through holes 2, 2... bored in the inner cylinder part 1...
The diameter of the opening is selected to be such that the cleaning liquid supplied under pressure into the hollow part 5 can be sprayed vigorously, and the cleaning liquid is sprayed from all angles except directly below against the object W passing through the inner cylindrical part 1. It is arranged so that it can be sprayed on.

A chain conveyor 7 for transporting objects W to be cleaned into and out of the casing 4 is disposed along the outside of the casing 4 made up of the inner cylindrical portion 1 and the outer cylindrical portion 3.

The conveyance chain 8 of the chain conveyor 7 is slidably supported by a chain rail 9 disposed horizontally along the lower part thereof, and a plate-shaped mounting table 10 on which the object to be cleaned W is placed. is mounted horizontally.
