Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container cleaning device.

[0002]

[Prior art]

 In the conventional cleaning apparatus of this type, when cleaning the inside of the closed container 33 as shown in FIG. 3, the shower nozzle 35 is inserted through the opening 34 and the pressure water guided from the cleaning liquid tank 36 is stored in the container 33. It is washed by spraying or dipping.

[0003]

[Problems to be solved by the device]

 However, when the cleaning is performed as described above, the washed-out dust remains stored in the recess U, and the shadow S of the protrusion does not come into contact with the pressure water and remains uncleaned. There is. Further, since the waste liquid that has been washed flows out from the opening 34, the washing liquid is wasted and it is not preferable in terms of the environment. Furthermore, if a high-pressure plunger pump is used as the pressure water pump P in order to improve the cleaning effect, there is a problem that failures due to dust frequently occur.

In view of such conventional problems, the present invention supplies compressed air together with a cleaning liquid into a closed container to enhance the cleaning effect, and returns the cleaned liquid to the cleaning liquid tank to drain the waste liquid. It is an object of the present invention to provide a cleaning device for a container for which prevention is intended.

[0005]

[Means for Solving the Problems]

In order to achieve such an object, the structure of the present invention is, as shown in FIG. 1, an outer cylinder portion 12 fitted and attached to an opening portion V ₁ of a closed container V ₁ and having an upper end side opening 12a, and the outer cylinder portion. And a cleaning liquid supply pipe 14 having an injection nozzle 13 at the tip end, which is inserted along the axis of the portion 12, and a liquid supply pump 16 is provided in the middle of the supply pipe 14 connected to the cleaning liquid tank 15. A compressed air pipe 19 is connected to the downstream side thereof, and a return pipe 21 provided with a filter 23 and a drainage pump 22 is connected between the drainage port 20 of the outer cylinder portion 12 and the cleaning fluid tank 15.

[0006]

[Action]

 With the above configuration, in the configuration of the present invention, during cleaning, the cleaning liquid and the compressed air are strongly mixed and sprayed on the inner wall of the closed container V from the spray nozzle 13 to the inner wall of the closed container V, and the cleaning is performed without leaving any residue. To be done. Further, the washed liquid first flows in through the opening 12a of the outer cylinder portion 12, is sucked in the reflux pipe 21 by the drainage pump 22, passed through the filter 23, and then returned to the washing liquid tank 15.

[0007]

【Example】

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 1, a packing 11 is attached to the main body 10 of the cleaning device at an opening V ₁ of an airtight container V, which is an object to be cleaned, and an outer cylinder 12 having a bottom and an opening 12a at the upper end is fitted into the packing 11. is doing. A cleaning liquid supply pipe 14 provided with an injection nozzle 13 at the tip is penetrated along the axis of the outer cylinder portion 12, and the supply pipe 14 is guided to a cleaning liquid tank 15. Further, the supply pipe 14 is provided with a valve 17 and a gas-liquid mixer 18 on the downstream side of a liquid-sending pump 16 provided midway, and a compressed air pipe 19 is connected to the gas-liquid mixer 18.

On the other hand, a drainage port 20 is provided in the outer cylinder portion 12, a reflux pipe 21 is connected between the drainage port 20 and the cleaning fluid tank 15, and a pump 22 and a filter are provided in the middle thereof. 23 are provided. For cleaning, first, the injection nozzle 13 is inserted into the container from the opening V ₁ of the closed container V which is the object to be cleaned, and at the same time, the packing 11 is brought into close contact with the opening V ₁ .

Then, a liquid in which the cleaning liquid and the compressed air are mixed is jetted from the jet nozzle 13, and a strong vortex is generated in the mixed liquid in the closed container V, so that the dust adhered to the wall surface is surely removed. In addition, the cleaning liquid is strongly applied to the shadowed portion V ₂ of the protruding portion, and the inner wall is evenly cleaned. Further, the above-mentioned cleaning liquid is poured into the closed container V to a full state, the inside of the container is constantly agitated, and the dust floats. The cleaning liquid tank 15 is recirculated into the cleaning liquid tank 15. That is, since the amount of the cleaning liquid flowing into the container V is substantially equal to the amount of the cleaning liquid flowing out, a clean cleaning liquid is always circulated in the container V, and no sedimentation or unstained residue of dust occurs. Since the injection nozzle 13 rotates, the injection is not biased, and since the liquid delivery pump 16 can use a low-pressure centrifugal pump, the flow rate is greatly increased compared to the plunger pump, and the cleaning power is increased accordingly.

Next, a second embodiment of the present invention will be described with reference to FIG. Reference numeral 24 denotes a container for the object to be cleaned, which is installed above the cleaning liquid tank 25 and has an open upper surface. A drain pipe 26 provided with a valve is connected between the lower end of the container 24 and the cleaning liquid tank 25. Reference numeral 27 denotes a liquid feed pump installed on the cleaning liquid tank 25. The suction pipe 27a is put in the cleaning liquid tank 25, and the discharge pipe 27b provided with a gas-liquid mixer 28 in the middle is put in the container 24. A compressed air pipe 29 is connected to the gas-liquid mixer 28.

The cylinder device 30 installed above the container 24 is provided with a cleaning member 31 extending downward. For cleaning the inside of the container 24, first, the cleaning liquid and compressed air are supplied into the container 24, and then the cylinder device 30 is operated to vertically move the cleaning member 31 inserted in the container 24. As a result, the cleaning liquid is vigorously stirred, and as a result, dirt on the inner wall of the container 24 is sufficiently removed. After cleaning, the liquid in the container 24 is returned to the cleaning liquid tank 25 via the drain pipe 26. A filter 32 for receiving drainage is provided in the cleaning liquid tank 25. Further, the operation of the cylinder device 30 and the liquid feed pump 27 is set to be automatically performed by the control device. Further, an overflow pipe is attached between the container 24 and the cleaning liquid tank 25.

[0012]

[Effect of device]

 According to the present invention, since the cleaning liquid and the compressed air are mixed and jetted into the container of the object to be cleaned and strongly stirred, the dust adhering to the inner wall is reliably removed, and the dust remains as in the past. There is no wash leak. In addition, since a low-pressure centrifugal pump can be used as the cleaning liquid delivery pump, the flow rate can be increased and cleaning power can be increased, unlike conventional plunger pumps. In addition, since the washed liquid can be returned to the cleaning liquid tank, cost savings and pollution prevention can be achieved. In addition, unlike the conventional device, there are few moving parts such as expansion and contraction of the nozzle, so that there is an effect that failures are reduced accordingly.
