Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a workpiece ultrasonic cleaning device for continuously ultrasonically cleaning a workpiece.

(Prior Art) Conventionally, there is an ultrasonic cleaning method as a method for cleaning works such as nuclear fuel sintered bodies of uranium No. 325 (hereinafter referred to as pellets) in nuclear fuel manufacturing processes. In this method, a workpiece is placed in a cleaning tank that incorporates a vibrator connected to an ultrasonic oscillator, and the workpiece is cleaned using cleaning water as a medium by the vibration of the vibrator.

This ultrasonic cleaning method is suitable for cleaning pellets and other works that affect the human body and are brittle and easily damaged.

(Problems to be solved by the invention) However, in this ultrasonic cleaning method,
As a means of taking workpieces into and out of the cleaning tank,
There were cases where this was done by a person by remote control, and cases where a conveyance device such as a conveyor was used.

However, when cleaning is done manually, there are problems in that there is a risk of harming the human body, it is time-consuming, and it is not possible to clean continuously. Furthermore, when a conveyor or other conveyance device is used, the conveyance device must be incorporated into the cleaning tank, which requires a larger cleaning tank.
Therefore, a problem arose in that the entire ultrasonic cleaning device also became larger.

An object of the present invention is to solve the above problems and provide an ultrasonic cleaning device for workpieces that is small and can automatically and continuously clean the workpieces.

(Means for Solving the Problems) The present invention, as a means to solve the above problems, rotates in a vertical plane around a horizontal axis and immerses the lower part in an ultrasonic cleaning tank. A disc-shaped rotating body, a workpiece storage section consisting of a plurality of through holes provided on the peripheral edge of the rotating body and penetrating in the horizontal direction, and a plurality of throughholes smaller than the outer shape of the workpiece,
a work fall prevention member provided close to both sides of the rotating body in the ultrasonic cleaning tank;
It is equipped with the following.

(Function) With this configuration, by rotating the rotating body that holds the workpieces inserted into the workpiece storage section consisting of the through hole, the workpieces are immersed in the ultrasonic cleaning device one after another and cleaned. can be performed continuously.

In addition, since fall prevention members with multiple through holes are provided close to both sides of the rotating body, the workpiece will not fall out of the workpiece storage area even if the workpiece is vibrated by ultrasonic waves. The workpiece is held in a fixed position in the workpiece storage section and cleaned.

(Example) Next, an example of the present invention will be described using FIGS. 1 to 4.

At the periphery of the disc-shaped rotating body 1 that rotates in a vertical plane about a horizontal axis S, there are workpiece storage sections 3, 3, . There are several.

This rotating body 1 is adapted to be rotated by a rotating device (not shown), and this rotating body 1
The lower part of is immersed in the cleaning water 5 in the ultrasonic cleaning tank 4.

The ultrasonic cleaning tank 4 includes a vibrator 6 connected to an ultrasonic oscillator (not shown) that generates ultrasonic waves. Further, in the ultrasonic cleaning tank 4, a workpiece fall prevention member is installed along the periphery of the rotary body 1 so as to be close to both side surfaces of the rotary body 1 and cover the workpiece storage sections 3, 3, which are formed of through holes, from both sides. 7 is provided. The workpiece fall prevention member 7 is made of a generally semi-circular plate, has a large number of through holes 8 smaller than the outer shape of the workpiece 2, and is fixed to the ultrasonic cleaning tank 4 by welding or the like. Of course, a wire mesh may be used as the member for preventing the workpiece from falling off.

In addition, 9 is a level sensor that detects the water level of the cleaning tank 5, and thereby the water supply port 10, the drain port 1
Supply and drain cleaning water from 1 to maintain the water level.

Next, to explain the operation of this device, first, when the ultrasonic oscillator is activated, the vibrator 6 connected to it vibrates in the cleaning water 5, and this vibration is transmitted to the rotating body through the cleaning water 5. The ultrasonic waves propagate to the works 2, 2, . . . inserted into the work storage sections 3, 3, . . . At this time, the rotating body 1 is being rotated, so the works 2, 2, . . . are continuously cleaned.

Furthermore, since the workpiece fall prevention member 7 is provided with the through hole 8, the vibrations of the oscillator will be propagated to the workpiece through the through hole, and therefore cleaning will not be prevented.

In particular, this device may not affect the human body or
It is effective for cleaning pellets, etc., which are brittle and easily damaged.

(Effects of the invention) Since the invention has the configuration described above,
The ultrasonic cleaning work of pellets and other works can be streamlined, and work efficiency can be improved because the works can be washed continuously.

In addition, by preventing the workpiece from falling off,
There is no need to stop the operation of the device, and there are effects such as improved economic efficiency.
