Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cleaning device for cleaning an object to be cleaned using a cleaning liquid.

[Prior Art] Conventionally, this type of cleaning equipment includes an immersion cleaning tank for immersing and cleaning objects to be cleaned, a steam cleaning tank equipped with a heater at the bottom, and a vacuum cleaner between the immersion cleaning tank and the steam cleaning tank. a rinsing tank disposed in the rinsing tank, the cleaning liquid in the rinsing tank overflows from the rinsing tank to the immersion cleaning tank, and the cleaning liquid in the immersion cleaning tank overflows from the immersion cleaning tank to the steam cleaning tank, After the dirty cleaning liquid in the steam cleaning tank is introduced into a distillation device installed separately from the cleaning device and distilled, the cleaning liquid is kept clean by flowing into the cleaning device again. It is known that cleaning is performed by moving objects to be cleaned in the order of cleaning tanks.

[Problems to be solved by the invention] However, the dirty cleaning solution in the immersion cleaning tank where the first cleaning of the object to be cleaned is carried out overflows into the steam cleaning tank where the subsequent cleaning is carried out. When cleaning in a tank, impurities in the cleaning liquid in the tank adhere to the objects to be cleaned, reducing the cleaning ability, resulting in problems such as the need to replace the cleaning liquid every short period of time.

[Purpose of the invention] The present invention solves the above problems,
It is an object of the present invention to provide a cleaning device that can keep cleaning liquid in each cleaning tank clean at all times and can reliably clean objects to be cleaned.

[Means for Solving the Problems] In order to achieve the above object, in the present invention, a distillation tank equipped with a heater at the bottom is arranged near each washing tank, and the washing liquid in the finishing washing tank is heated. An overflow means is provided for overflowing the cleaning liquid in the immersion cleaning tank to the distillation tank as well as to the rinsing tank, and the cleaning liquid is cooled and liquefied by the cooling means disposed above each tank. A supply means is provided for supplying the finish cleaning tank.

[Function] With the above-described configuration, the present invention allows the dirty cleaning liquid in the immersion cleaning tank and the finishing cleaning tank to overflow into the distillation tank and the rinsing tank, respectively, and the vaporized vapor in each tank is cooled and liquefied by the cooling means. The cleaning liquid in each cleaning tank is always kept clean.

[Example] An example in which the present invention is embodied in an ultrasonic cleaning device will be described below with reference to the drawings.

The ultrasonic cleaning device 1 has two chambers 1 that are open upward.
It has a machine frame 9 with chambers 2 and 13, one of which has a chamber 1.
2 includes an immersion cleaning tank 2 with an ultrasonic vibrator 3 attached to the lower surface, a finishing cleaning tank 4 equipped with a heater 5 at the bottom for boiling cleaning, and a space between the immersion cleaning tank 2 and the finishing cleaning tank 4. A rinsing tank 6 is provided. Further, the other chamber 13 is provided with a distillation tank 22 equipped with a heater 20 at the bottom.
Each of the layers 2, 4, 6, and 22 contains a fluorocarbon cleaning liquid.

A cooling pipe 15 disposed along the inner peripheral surface of the chamber 12 is attached to the upper part of the chamber 12, and cools and liquefies the fluorocarbon vapor vaporized in the immersion cleaning tank 2, the rinsing cleaning tank 6, and the finishing cleaning tank 4. This prevents freon vapor from leaking out of the device. Similarly, a cooling pipe 25 is attached to the upper part of the chamber 13 along the inner circumferential surface of the chamber 13, and cools and liquefies the fluorocarbon vapor heated and vaporized in the distillation tank 22 so that the fluorocarbon vapor flows out of the apparatus. is prevented. Below the cooling pipes 15 and 25 are installed gutter pipes 16 and 26 which are connected to each other, and a pipe 17 extending to the finish cleaning tank 4 is connected to the gutter pipe 16.

A notch 7 is formed in the upper part of the opposing side walls 2a and 6a of the immersion cleaning tank 2 and the rinsing tank 6, and the cleaning liquid in the rinsing tank 6 flows over the notch 7 into the immersion cleaning tank 2. In addition, a notch 8 is formed in the upper part of the opposing side walls 6b and 4a of the finishing cleaning tank 4 and the rinsing cleaning tank 6.
The cleaning liquid overflows over the notch 8 into the rinsing tank 6. A pipe 18 is connected between the immersion cleaning tank 2 and the distillation tank 22, which is attached to the back side of the machine frame 9 and is inclined so as to be gradually lowered toward the distillation tank 22 side. Then, the cleaning liquid in the immersion cleaning tank 2 is overflowed to the distillation tank 22 through the pipe 18, and the liquid level in each tank 2, 4, 6, 22 is adjusted to the finishing cleaning tank 4, the rinsing cleaning tank 6, and the immersion cleaning tank 2. and the distillation tank 22 are configured to be lower in this order.

The present embodiment is constructed as described above, and its operation will be explained next.

First, the object to be cleaned 19 is steam cleaned in the distillation tank 22, and then moved to the immersion cleaning tank 2, the rinsing cleaning tank 6, and the finishing cleaning tank 4 in this order for cleaning. The cleaning liquid contaminated in the immersion cleaning tank 2 by cleaning the object 19 to be cleaned is introduced into the distillation tank 22 via the pipe 18, and the cleaning liquid contaminated in the finishing cleaning tank 4 is transferred to the notch 8, Distillation tank 22 via rinsing tank 6, notch 7, immersion cleaning tank 2 and pipe 18
The steam is then heated and vaporized again by the heater 20, and the steam cleans another object 19 to be cleaned.

Then, the steam that did not adhere to the object to be cleaned 19 during the steam cleaning further rises, is cooled and liquefied by the cooling pipe 25, and is dripped into the gutter pipe 26. Further, the steam vaporized in each of the cleaning tanks 2, 4, and 6 is cooled and liquefied by the cooling pipe 15, and dripped into the gutter pipe 16. The clean cleaning liquid dripped into the gutter pipes 16 and 26 is supplied to the finishing cleaning tank 4 via the pipe 17.

Therefore, all the dirty cleaning liquid is introduced into the distillation tank 22, and the clean cleaning liquid distilled in the distillation tank 22 is supplied to the finishing cleaning tank 4, so that the cleaning liquid in each of the cleaning tanks 2, 4, and 6 is constantly circulated. and be purified. In addition, the cleaning process of the object 19 to be cleaned is performed in the distillation tank 2.
After steam cleaning in step 2, each cleaning tank 2, 4,
Since cleaning is performed in step 6, it is possible to remove a certain amount of dirt from the object 19 to be cleaned before the cleaning is started in the immersion cleaning tank 2, and the object 19 to be cleaned can be reliably cleaned. Furthermore, since the distillation tank 22 is integrated with the cleaning device, the entire device can be made smaller.

In this embodiment, a cleaning device using ultrasonic waves has been described, but a cleaning device using a jet or the like may also be used. Furthermore, although boiling cleaning has been described as a cleaning method in the finishing cleaning tank, steam cleaning may also be used.

[Effects of the invention] As detailed above, in the present invention, the dirty cleaning liquid in the immersion cleaning tank and the finishing cleaning tank overflows into the distillation tank and the rinsing tank disposed near each cleaning tank, and also Since the distilled clean cleaning liquid is supplied to the finishing cleaning tank, the cleaning liquid in each cleaning tank can be kept clean at all times, and the objects to be cleaned can be reliably cleaned.
