BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container cleaning apparatus.

[0002]

2. Description of the Related Art A conventional cleaning apparatus of this type inserts a shower nozzle 35 through an opening 34 thereof and cleans the cleaning liquid tank 3 when cleaning the inside of a closed container 33 as shown in FIG.
Cleaning is performed by spraying or dipping the pressurized water guided from 6 into the container 33.

[0003]

However, when the washing is performed as described above, the washed-out debris may remain in the recessed portion U, or if the pressurized water hits the portion S behind the protrusion. There is a problem that uncleaned portions remain.
Further, since the washed waste liquid drips from the opening 34, the washing liquid is wasted and the environment is not preferable.
Further, when a high-pressure plunger pump is used as the pressure water pump P in order to enhance the cleaning effect, there is a problem that breakdown due to dust frequently occurs.

In view of the above-mentioned problem, the present invention improves the cleaning effect by supplying compressed air together with the cleaning liquid into the closed container, and also 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 container cleaning device in which prevention is achieved.

[0005]

To achieve Means for Solving the Problems] Such object, the present invention apparatus, the outer cylinder portion (12 to be inserted inside the opening from (V ₁₎ of the container vessel (V) to be cleaned )
A cleaning liquid supply pipe provided with a rotary injection nozzle (13) at a portion extending into the container (V) through the inside of the outer cylinder portion (12) and extending outward from the open end of the outer cylinder portion; (14), and the other end of the cleaning liquid supply pipe (14) is connected to the cleaning liquid tank (1).
5) A container cleaning device which is connected to the cleaning liquid tank (15) while being connected to the cleaning liquid tank (15) while being connected to the drain pipe (21) of the outer cylinder part (12).
Downstream of a low pressure type liquid feed pump (16) provided in the middle of the washing liquid supply pipe (14), the liquid feed pump (1) is provided.
6) Cleaning fluid and compressed air pipe (1)
The cleaning liquid and the compressed air are ejected in a mixed state from the rotary injection nozzle (13) by interposing a gas-liquid mixer (18) for mixing the compressed air supplied through 9). A filter (23) and a drain pump (22) are provided in the conduit of the reflux pipe (21).

[0006]

According to the structure of the present invention, the cleaning liquid and the compressed air are jetted from the injection nozzle 13 in a mixed state to the inner wall of the closed container V in a mixed state, and are strongly sprayed to the inner wall of the closed vessel V without washing. Washed. Further, the washed liquid first flows in through the opening 12a of the outer cylinder portion 12 and flows through the return pipe 2
The inside of 1 is sucked by a drainage pump 22, passed through a filter 23, and then returned to a cleaning liquid tank 15.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. In Figure 1, the opening V ₁ of the closed container V to be cleaned, the packing 11 attached to the cleaning device main body 10, the upper end side to the packing 11 is fitted to the outer tube 12 of the opening 12a and a bottom I have. A cleaning liquid supply pipe 14 provided with a jet nozzle 13 at the tip along the axis of the outer cylinder 12 is penetrated, and the supply pipe 14 is guided to a cleaning liquid tank 15.
The supply pipe 14 is provided with a valve 17 and a gas-liquid mixer 18 on the downstream side of a liquid feed pump 16 provided in the middle, 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 part 12, and a reflux pipe 21 is connected between the drainage port 20 and the cleaning liquid tank 15, and a pump 22 and a filter 23 are provided in the middle thereof. Is provided. It washed first, from the opening V ₁ of the closed container V to be cleaned, to close contact with the packing 11 to the injection nozzle 13 into the opening V ₁ and at the same time inserted into the container.

Then, a liquid in which the cleaning liquid and the compressed air are mixed is injected from the injection nozzle 13, and the mixed liquid generates a strong vortex in the closed container V, so that the dust adhered to the wall surface is reliably removed. Moreover, the shaded portion V _{2 of the} protrusion
Also, the cleaning liquid is strongly applied, and the inner wall is washed evenly. Further, the cleaning liquid is poured into the closed container V until the container is completely filled, the container is constantly stirred, and dust is floated. These cleaning liquids are sucked through the opening 12 a of the outer cylinder 12, pass through the return pipe 21, and pass through the filter 23. And is returned to 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 therethrough, the cleaning liquid always circulates in the container, so that no sedimentation of the dust or residue of the dirt is generated. Since the injection nozzle 13 rotates, the injection is not biased, and the liquid sending pump 16 can use a low-pressure centrifugal pump. Therefore, the flow rate is greatly increased as compared with 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, and a cleaning liquid tank 25.
And is open at the top. This container 24
A drain pipe 26 provided with a valve is connected between a lower end of the cleaning liquid tank 25 and the cleaning liquid tank 25. Reference numeral 27 denotes a liquid feed pump installed on the cleaning liquid tank 25, and connects the suction pipe 27a to the cleaning liquid tank 2
5, a discharge pipe 27 provided with a gas-liquid mixer 28 in the middle
b is placed in the container 24. The gas-liquid mixer 28
Is connected to a compressed air pipe 29.

The cylinder device 30 installed above the container 24 has a cleaning member 31 extending downward. The cleaning of the container 24 is performed by first supplying the cleaning liquid and the compressed air in the container 24 in a mixed state, and then operating the cylinder device 30 to clean the cleaning member 3 inserted into the container 24.
1 is moved up and down, and the cleaning liquid is vigorously stirred. As a result, dirt on the inner wall of the container 24 is sufficiently removed. After the 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. 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]

[Effects of the Invention] According to the present invention, in the container of the object to be cleaned,
Since the cleaning liquid and the compressed air are mixed and jetted and stirred vigorously, the dust adhered to the inner wall is reliably removed, so that the dust does not remain or the cleaning leak is eliminated as in the related art. In addition, since a low-pressure centrifugal pump can be used as the cleaning solution supply pump, unlike a conventional plunger pump, the flow rate can be increased and the cleaning power can be increased. Further, since the washed liquid can be returned to the washing liquid tank, cost can be reduced and pollution can be prevented. Further, unlike the conventional apparatus, there are few movable parts such as expansion and contraction of the nozzle, so that there is an effect that the number of failures is reduced accordingly.
