Abstract

PURPOSE:To ameliorate contact of a material to be cleaned with a cleaning soln. and to improve cleaning efficiency by sucking the cleaning soln. in a cleaning tank, injecting the soln. against an impeller from a nozzle and rotating a cleaning basket fixed to the impeller. CONSTITUTION:The cleaning tank 1 is airtightly closed by a lid 2, and a feed pump 10 is operated to suck the cleaning soln. in the tank 1 into the pump 10 through a suction pipe 7. The sucked soln. is sent to the nozzle 12 in the tank 1 via a discharge pipe 11 and injected against the impeller 6. Consequently, the impeller 6 is rotated with the shaft 5 as the center by the kinetic energy of the soln., and the cleaning basket 4 fixed to the impeller 6 is also rotated with the shaft 5 as the center. A material to be cleaned in the cleaning basket 4 is rotated in the soln. The material such as a magnetic material is efficiently cleaned in the soln. in this way.

Description

Detailed Description of the Invention (Field of Industrial Application) The agitation cleaning device according to the present invention can be used to clean objects to be cleaned such as various metal parts in an organic solvent such as Freon. It is used for efficient cleaning by stirring.

(Prior Art) Various cleaning devices for cleaning various metal parts using organic solvents such as fluorocarbons have been known.

Furthermore, in order to prevent organic solvents such as fluorocarbons from having an adverse effect on the environment, various structures have been known for devices that seal cleaning tanks and recover organic solvents used in cleaning operations.

(Problems to be Solved by the Invention) However, in the case of a cleaning device having a structure in which the cleaning tank is sealed as described above, the following disadvantages occur.

That is, in the case of an object to be cleaned that is heavily soiled or an object to be cleaned that has a complicated surface shape, it is effective not only to immerse the object to be cleaned in an organic solvent, but also to stir the object to be cleaned in the organic solvent.

There are two methods for stirring the objects to be cleaned in a sealed cleaning tank: a method using a drive shaft that penetrates the wall of the cleaning tank, and a method using a magnetic coupling.
In the former case, it is difficult to maintain air-tightness and liquid-tightness in the portion through which the drive shaft penetrates, and in the latter case, there is a problem that it cannot be used when the object to be cleaned is made of a magnetic material.

For this reason, conventionally, the organic solvent sucked out from the bottom of the cleaning tank is jetted out from a nozzle installed at the top of the cleaning tank, thereby causing a flow in the organic solvent in the cleaning tank, which brings the object to be cleaned and the organic solvent into contact with each other. Efforts have been made to improve the situation, but it has not always been possible to obtain a sufficient cleaning effect.

The agitation cleaning device of the present invention eliminates the above-mentioned disadvantages.

(Means for Solving the Problems) The agitation cleaning device of the present invention includes a cleaning tank which can be sealed with a cleaning liquid stored therein, and a cleaning tank which can be freely rotated around a shaft provided in the cleaning tank, and has a cleaning solution inside the cleaning tank. A cleaning basket that can freely store cleaning items, an impeller installed on a fixed part of the cleaning basket centered around the shaft, and a suction pipe whose end opens into the cleaning tank, and the cleaning liquid is sucked in and discharged from the discharge port. A liquid feeding pump, a discharge pipe having one end connected to the discharge port of the liquid feeding pump and penetrating the wall surface of the Kamikita cleaning tank, and a discharge pipe provided at the other end of the discharge pipe and opening toward the impeller. It consists of a nozzle.

(Function) In the case of the stirring cleaning device of the present invention configured as described above, the cleaning liquid in the cleaning tank is sucked by operating the liquid pump, and when this cleaning liquid is jetted from the nozzle toward the impeller, this A cleaning basket fixed to the impeller rotates around a shaft, and the object to be cleaned stored in the cleaning basket is stirred in the cleaning liquid.

As a result, the contact between the object to be cleaned and the cleaning liquid becomes extremely good, and the cleaning efficiency of the object to be cleaned is improved.

(Example) Next, the present invention will be explained in more detail while explaining the illustrated embodiment.

The drawing is a transparent perspective view showing an embodiment of the agitation cleaning device of the present invention.

Reference numeral 1 denotes a cleaning tank having a cylindrical shape with a bottom, in which a cleaning liquid such as fluorocarbon can be freely stored. This cleaning tank 1
A lid 2 made of acrylic plate or the like can be freely attached to the upper opening, and a backing is attached between the bottom surface of M2 and the opening edge of the cleaning tank 1, so that when M2 is closed, It is designed to maintain airtightness inside and outside the cleaning tank 1.

In the cleaning tank 1, a cylindrical cleaning basket 4 is disposed in the middle between a pair of support brackets 3.3 spaced apart from each other.
Both ends of the shaft 5 are rotatably supported. An impeller 6 centered on the shaft 5 is fixed on the side surface of the cleaning basket 4, which can freely store items to be cleaned inside.By rotating this impeller 6, the shaft 5 is attached to the support bracket 3.3. The washing basket 1 provided at the middle part of the shaft 5 rotates.

In addition, at least any part between both ends of the cleaning basket 4 and the shaft 5, between both ends of the shaft 5 and the support bracket 3.3, or between the support bracket 3.3 and the bottom surface of the cleaning tank 1 is designed to be detachable. , it is possible to easily carry out the work of loading and unloading objects to be cleaned into the cleaning basket 4.

On the other hand, the other end of the suction pipe 7, which has one end opened at the bottom of the wash off 1 and a solenoid valve 8 and a gate valve 9 provided in series with each other, is connected to the suction port of the liquid pump 10. There is.

Further, one end of the discharge pipe 11 is connected to the discharge port of the liquid pump 10, and a nozzle 12 is provided at the other end of the discharge pipe 11 that penetrates the wall surface of the cleaning tank 1 and opens inside the cleaning tank 1. The opening of this nozzle 12 is directed toward the impeller 6.

In the drawings, reference numeral 13 indicates a solenoid valve provided in the middle of the discharge pipe 11.

In the case of the stirring cleaning device of the present invention configured as described above, by operating the liquid feed pump 10 with the upper end opening of the cleaning tank 1 airtightly closed with the lid 2, the cleaning tank 1 is supplied through the suction pipe 7. The cleaning liquid inside is sucked into the liquid feeding pump 10.

The cleaning liquid sucked into the suction pipe 10 in this manner is then sent to the nozzle 12 in the cleaning tank 1 through the discharge pipe 11, and is ejected from the opening of this nozzle 12 toward the inflator 6.

As a result, the impeller 6, based on the kinetic energy of the cleaning liquid,! The cleaning basket 1, which rotates around the impeller 6 and is fixed to the impeller 6, also rotates around the shaft 5, and the object to be cleaned stored in the cleaning basket 1 is stirred in the cleaning liquid.

As a result, the contact state between the object to be cleaned in the cleaning basket 1 and the cleaning liquid becomes extremely good, and the cleaning efficiency of the object to be cleaned is improved.

Note that the impeller 6 can also be provided at the end of the shaft 5.

(Effects of the Invention) Since the agitation cleaning device of the present invention is configured and operates as described above, there is no need to provide a troublesome seal to keep the cleaning tank liquid-tight, and it is not necessary to install a troublesome seal on the cleaning tank to keep it liquid-tight. including the items to be cleaned,
Various objects to be cleaned can be efficiently cleaned in the cleaning liquid.
