In addition, in FIG. 2, the code group is a drain pipe, and a drain valve is provided in the middle. Also, supply piping system I
A branched pipe 57 extends from the pre-cleaning tank 14 side, and a valve swamp is provided in the middle of this pipe 57, and by opening the valve 58 as necessary, various parts can be cleaned by hand. It has become.

Next, the cleaning action by the cleaning device fK will be explained.

In the preparation stage before operation, the control valve 47 is activated as shown in FIG.
, 48 are closed, and the other control valves 51 and 52 are opened. (In this state, when cleaning work is to be performed, the control valve 47 is opened and the control valve 51 is closed, as shown in FIG. 5. Pressure air is supplied from the air supply source K through the supply piping 45 into the first storage tank 16 to push down the liquid level of the stored cleaning liquid and act 471. Due to this pump action, the first storage tank The cleaning liquid 15 stored in the cleaning basket 16 passes through the first supply pipe 22 and the A body turn & joint 32 of the supply piping system, and is delivered from each injection nozzle 31 of the nozzle device 21 to the object to be cleaned stored in the cleaning basket 13. It is sprayed at the gate.

At that time, a part of the cleaning liquid supplied from the storage tank 16 passes through the Mlft body ejection pipe 26Y to the support ring 3 of the nozzle device B.
4, and this discharge pressure is received by the pressure receiving surface of the cut and raised cylinder. Due to this busy schedule, the nozzle device 4 is the 611th!
It is rotated counterclockwise as shown in JK, and by the rotation of this nozzle device B, the cleaning liquid is sprayed over the entire surface of the object to be cleaned, thereby performing cleaning.

After cleaning the object, the cleaning liquid sprayed toward the object to be cleaned passes between the meshes of the cleaning basket 13, falls into the cleaning side 12, and is stored. The stored cleaning liquid is then purified by a filter tube, passes through a return pipe 381, and is returned to the second storage tank 17. At this time, the check cut in the return pipe is blocked by the pressure of the cleaning liquid on the first storage tank side. In addition, the inside of the second storage tank 17 is connected to the siren 4I-
Since the tank 53 is open to the atmosphere, the cleaning liquid in the cleaning tank 12 is smoothly returned through the return pipe 38v and is filled.

The amount of cleaning liquid supplied in the wcl storage tank 16 is time-controlled by a timer (not shown), etc., and when a sufficient amount of cleaning liquid is supplied, the control valves 47, 48, 51, and 52 are switched to open and close, as shown in FIG. As shown, control valves 48, 51 are open and other control valves 47, 52 are closed.

From this K, the pressurized air is transferred to the second storage tank 17I111.
1K is supplied, and due to the pump action of this pressurized air, the cleaning liquid in the second storage tank 17 passes through the second supply piping 23% fluid rotary joint 32 of the supply piping system to the nozzle device 2.
1, and is sprayed from a large number of spray nozzles 31 toward the object to be cleaned, thereby cleaning the object.

After this, a part of the cleaning liquid supplied is @22 parts spout pipe 2.
7 and is injected toward the support R34I/C of the nozzle device 21, and its discharge pressure is received by the cut and raised pressure receiving surface of the support ring. From this K, the nozzle device 21 is rotated clockwise around the vertical axis of the fluid rotary joint, as shown in Figure @8. By spraying the cleaning U from each injection nozzle of the nozzle device while rotating the nozzle device clockwise, the object to be cleaned vIV can be effectively cleaned.

Cleaning liquid used to clean the object to be cleaned and cleaning/9-sket piping 3
8 to the first storage tank 16 and stored in this tank 16.

At this time, the first storage tank 16 yen is opened to the atmosphere via the air supply pipe 45 and the branch pipe 49 through the silencer group, so the cleaning liquid passing between the return pipes is transferred to the first storage tank 16.
You will be guided smoothly inside 6. The return flow to the second storage tank 17 is restricted by closing the check valve 41.
Regulated. This check valve 41 is closed by the hydraulic pressure of the second storage tank 17.

When a certain amount of the cleaning liquid in the second storage tank 17 is supplied (this is time-controlled using a timer or the like (not shown)),
Control valves 47, 48, 51, and 52 are automatically opened and closed. Thereafter, the cleaning operations are sequentially switched and the cleaning action continues automatically and continuously to clean the object to be cleaned.

At that time, the cleaning time of the object to be cleaned is appropriately determined depending on its shape, size, amount, etc., and the injection force injected from each injection nozzle of the nozzle device is adjusted by controlling the pressure of pressurized air. This is done by

Note that in *1 of an embodiment of the present invention, the cleaning basket is fixedly installed and rotated around the vertical axis on the nozzle device i1, so as shown in FIG. 9, The cleaning basket 56 may be rotatably supported by the nozzle assembly #55. In this case, it is necessary to install a large number of pressure receiving plates 57t at equal intervals on the outer surface of the cleaning plate 56.

Also, $1 and the second fluid ejection pipes 26 and 27, respectively? It is also possible to provide one each, and each fluid ejection pipe!
It is not necessary to branch out from the supply piping system, and each fluid ejection pipe can be used as a fluid outlet. Nump etc! may be connected directly to a fluid source via 0. ,.

Furthermore, it is not necessarily necessary to install a plurality of storage tanks, and there may be -. In this case, a check valve installed in the supply piping system becomes unnecessary, and the first and second fluid jet pipes are branched from one supply pipe, allowing each of the five branched fluid jet pipes to be used selectively. K. It is necessary to install a switching valve.

Advantages of the Invention First and second, the nozzle device or the nosuke can be selectively rotated alternately clockwise and counterclockwise by the hydraulic pressure of the fluid ejected from the fluid ejecting pipe. Since the nozzle device and the nozzle socket can be relatively rotated and the rotation can be performed reversibly, uneven cleaning can be eliminated and the object to be cleaned can be effectively and efficiently cleaned.
