Description

[Detailed description of the invention] This invention relates to a device that cleans the inside and outside surfaces of empty plastic bags, for example, in which chemical products, medicines, etc. are packed. The purpose is to provide.

In chemical factories, large amounts of chemical products and drugs (hereinafter referred to as drugs, etc.) such as raw materials and auxiliaries are used, but these drugs are usually packed in plastic bags and supplied to the chemical factory, and the use of the drugs, etc. In this case, the plastic bag is opened and used for a predetermined purpose, but when drugs and the like are used on a large scale, many used empty bags are generated.

Empty bags like this are usually disposed of or incinerated, but there are many drugs and other substances that are legally designated as dangerous substances or are poisonous, so empty bags that contain such substances are often discarded or incinerated. It is extremely dangerous to discard or incinerate the bags as they are, so when disposing of empty bags that have traditionally been filled with such drugs, wash the inner and outer walls of the empty bags with water beforehand. Chemicals and the like adhering to the inner and outer walls were completely washed away.

By the way, in the past, when washing the inner and outer walls of empty bags as described above, the worker used a rubber hose to perform each step, which was extremely time-consuming and labor-intensive, and it was difficult to completely remove adhering chemicals, etc. Not only is it difficult to do this, but the droplets often fall onto the clothes and skin of workers, which is extremely inconvenient in terms of health and safety.

The present invention has been devised to eliminate these conventional inconveniences and to provide a device for cleaning the inner and outer walls of the empty bags more effectively, safely and hygienically. 1, a frame 5 erected on this pedestal 1, a horizontal water sprinkling pipe 10 for cleaning the inner wall of empty bags, which is provided at the upper end of this frame 5 and has a water sprinkling hole 11 facing upward; An upper frame body 12 is provided on the water spray pipe 10 for cleaning the inner wall of the bag, and an upper frame body 12 is provided above the water spray pipe 10, and a water spray hole 8 facing downward is disposed above and parallel to the upper frame body 12. The frame body 5 has an inverted V-shaped water pipe 7 when viewed from the side.
The empty bag cleaning device has a pair of legs in the shape of a letter and is adapted to be placed over an upper frame 12 and a frame 5 with the empty bag 2 facing downward.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

Reference numeral 1 denotes a stand, and on the stand 1 there is a washing water main pipe 3 for supplying water for washing the empty bags 2, a washing water branch pipe 4 branched from the middle of the washing water main pipe, and a washing water branch pipe 4 for supporting the empty bags. A frame body 5 is erected. Further, a water supply pipe 6 is connected to the lower part of the main water pipe 3 for washing, and by opening and closing a water supply valve (not shown) provided in the water supply pipe 6, water for washing is supplied to the main water pipe 3 for washing. A cutoff occurs. A water spray pipe 7 for washing the front surface of an empty bag is connected to the top end of the main water pipe 3 for washing, which sprays water from above on the front side of the empty bag 2 supported by the frame 5 to wash it. At the same time, since the water sprinkling holes 8 are perforated downwardly in the water sprinkling pipe 7 in a substantially straight line at appropriate intervals, the frame 5 is covered by the spraying of washing water from the water sprinkling holes 8. The surface of the empty bag 2 that has been emptied and supported is washed with water.

Next, the washing water branch pipe 4 is connected to the washing water main pipe 3 by a connecting pipe 9, and the top of the washing water branch pipe 4 is connected to the back side of the empty bag 2 which is supported by covering the frame 5. A water sprinkling pipe 10 for washing the inner wall of the empty bag is connected to the water sprinkling pipe 10, and water sprinkling holes 11 are perforated upward in one or more rows almost in a straight line. Since the washing water is uniformly sprayed upward from the water sprinkling pipe 10 and flows down while wetting the inner wall of the empty bag 2, the chemicals and the like adhering to the inner wall of the empty bag are completely washed away. Reference numeral 12 denotes an arch-shaped upper frame which is supported on both sides of the upper surface of the water spray pipe 10 for cleaning the inner wall of the empty bag, and which is erected. The water sprinkling hole 1 does not cover the water sprinkling hole 11 of 10, and the water sprinkling hole 1
This is convenient because the spouting of washing water from No. 1 will not be obstructed. In addition, if each support of the frame 5 is made into a bifurcated shape as shown in FIG. 2, and the upper intersection point is fixed to the water spray pipe 10 for washing the inner wall of the empty bag, the structure will be strong and convenient. . Furthermore, if water sprinkling holes 13 are formed laterally in the cleaning water branch pipe 4, the cleaning water can be directly sprayed onto the side inner wall of the empty bag 2, thereby further improving the cleaning effect.

Since the present invention is constructed as described above, when cleaning the empty bag 2 for drugs, etc., first the empty bag 2 is cleaned.
Turn it upside down and firmly cover the frame 5 until the bottom comes into contact with the upper frame 12, and then open the water supply valve (not shown) provided in the water supply pipe 6 to clean the surface of the empty bag. Water sprinkling holes 8 and 1 of the water sprinkling pipe 7, the cleaning water branch pipe 4, and the water sprinkling pipe 10 for cleaning the inner wall of empty bags, respectively.
Washing water is simultaneously jetted from 3 and 11 to completely wash the front and back of the empty bag 2.

Since the present invention has been developed as described above, it is extremely easy to clean empty bags for drugs, etc., which conventionally required not only manpower and time but also problems in terms of health and safety, and can be done safely and completely in a short period of time. This is a useful idea. In addition, since the frame has a pair of inverted V-shaped legs when viewed from the side, the empty bag that is placed over the legs has its opening widened, so the empty bag does not come into close contact with the inside of the leg. Cleaning can be carried out efficiently by allowing the jetted cleaning water to flow down smoothly. Furthermore, a water sprinkling pipe for cleaning the inner wall of the empty bag is provided at the bottom of the upper frame, and the empty bag is designed to prevent the water sprinkling hole of the watering pipe for cleaning the inner wall of the empty bag from being blocked. Washing water gushing out from the sprinkling hole of the water pipe can be evenly sprayed onto the inner wall of the empty bag.
