Description

[Detailed Description of the Invention] [Object of the Invention] The present invention is capable of cleaning objects to be cleaned with adhered sludge, activated carbon, auxiliary agents, dirt, etc., using a minimum amount of water without damaging the objects. The present invention relates to a cleaning device configured as described above.

Various types of filters have traditionally been used to filter various plating solutions, industrial waste liquids, etc., but these filters allow the filtrate introduced into the device to pass through the filter media, allowing dirt to adhere to the filter media. I have to. Therefore, the filter medium is a vital part of the filter, and it must (i) be chemically stable (ii) have low flow resistance for the filtrate (iii)
) It is necessary to satisfy various conditions such as high strength against filtration pressure. The filter medium usually consists of a filter cloth covered over a sieve, but since the filter cloth is used repeatedly, it is required that it be easy to clean and that the fabric will not be damaged by washing.

In addition to these filters, a water washing method is used to wash various work clothes and other objects that have dirt attached to them.However, in the conventional water washing method, the washing method is carried out in a layer containing objects to be washed, like in a large washing machine. Dirt is removed by swirling water and rubbing the object to be cleaned, or by pouring water directly onto the object and removing the dirt with a brush or the like. However, with the former method, if the items to be washed are bulky or hard, the load becomes too large and the washing machine stops rotating, and the items to be washed rub against each other or are twisted. However, the latter method has the disadvantage that it requires an extremely large amount of water, making it uneconomical.

Unlike conventional washing methods, the present invention attempts to remove dirt without damaging the object with a relatively small amount of water, regardless of the type of object to be washed.

[Structure of the invention]

The present invention provides a state in which an object to be cleaned is housed in a cylindrical barrel having a required number of protrusions on the inner surface and a plurality of perforations around the periphery, and cleaning water of less than half of the volume of the barrel is present in the barrel. This is a cleaning device that rotates the barrel.

The present invention will be explained in detail below.

In the present invention, the object to be cleaned is housed in a cylindrical barrel, and by rotating this barrel, the object to be cleaned is brought into strong contact with the projections provided on the inner surface of the barrel, thereby removing dirt attached to the object to be cleaned. It is characterized by In this case, less than half of the volume of cleaning water exists in the barrel, and this cleaning water communicates with the outside through the perforations provided around the barrel, so the removed dirt is carried away to the outside through the perforations. .

If the amount of this cleaning water exceeds half of the barrel volume, the resistance will increase and the object to be cleaned will not come into strong contact with the protrusions, reducing cleaning efficiency, and the amount of cleaning water inside the barrel will become large relative to the external volume. This is undesirable because there is a high possibility that the dirt removed by the process will return to the barrel again.

As the material of the barrel, stainless steel, synthetic resin, etc. can be used without limitation, but in consideration of weight reduction, corrosion resistance, etc., it is preferable to use synthetic resin such as FRP. The perforations provided around the barrel are for transporting the dirt removed from the object to be cleaned to the outside together with water, and the diameter of the hole can be freely selected within a range that allows dirt and water to pass through, but not the object to be washed. I can do it. Further, the shape and material of the protrusions provided on the inner surface of the barrel are not limited as long as they can strongly contact the object to be cleaned and remove dirt.

The present invention will be described in more detail below based on embodiments shown in the drawings, but the present invention is not limited thereto.

FIG. 1 is a partially cutaway front view showing an embodiment of a cleaning device according to the present invention, and FIG. 2 is a cross-sectional view taken along the vertical line ``--'' in FIG.

Reference numeral 1 denotes the main body of the cleaning device, which has a horizontally cylindrical shape, a bottom surface inclined toward one side, and a cleaning water outlet 2 connected to the tip thereof, and the upper part of the main body 1 is open. A pair of mounting tables 5 on which a motor 3 and a bearing 4 are mounted are provided close to each other on both sides of the main body 1, and each of the bearings 4 has an inner wall that extends into the main body 1 through the side wall of the main body 1. An orientation axis 6 is provided.

A barrel 7, which has a horizontally cylindrical shape and is open at the front upper part, is rotatably spanned between the inner surfaces of the pair of opposing shafts 6. The inner surface of the barrel 7 is provided with four protrusions 8 having a V-shaped cross section by bending a rectangular plate in two at the center, and at an angle of 90 degrees. An arc-shaped lid 10 whose one end is pivoted to the edge 9 of the barrel 7 and can cover the opening is disposed at the opening, and the lid 10 has a retaining piece 11 provided at its tip. The opening is covered by engaging a handle 12 provided at the other end of the opening.

A plurality of perforations 13 are formed in the inner surfaces of the barrel 7 and the lid 10 where the protrusions 8 are not present, and the cleaning water 14 contained in the main body 1 flows into the barrel 7 through the perforations 13. It looks like this.

A removable downward dish-shaped lid body 1 is attached to the opening of the main body 1.
Covered by 5.

Next, an outline of how to use the device of this embodiment will be explained. First, the object to be cleaned is placed in the empty barrel 7. In this case, if the amount of objects to be cleaned is large, the resistance will be large and the objects to be cleaned will not come into sufficient contact with the projections 8, so an appropriate amount of objects to be cleaned should be accommodated. Subsequently, wash water 14 is poured into the main body 1 so that the amount of water in the barrel 7 becomes less than half. At this time, either adjust the pulp (illustration omitted) at the wash water outlet 2 to prevent the wash water 14 from flowing out, or
Allow a small amount to flow out. Then, the motor 3 is energized to rotate the shaft 6, thereby rotating the barrel 7, bringing the object to be cleaned inside the barrel 7 into contact with the protrusion 8, and removing the dirt into the cleaning water.

This dirt flows out into the main body 1 outside the barrel 7 through the perforations 13 together with the washing water. When the outlet 2 is open, this waste is taken out of the main body l, and even when the outlet 2 is closed, the amount of water inside the barrel 7 is quite small compared to the total amount of water, so it cannot be returned to the inside of the barrel 7. There are almost no Note that when the barrel 7 rotates frequently, the object to be cleaned comes into contact with the protrusions 8 evenly, so that the cleaning efficiency is improved.

Unlike the method of directly spraying water on the object to be cleaned to remove dirt, the device of this embodiment cleans the object in a predetermined amount of washing water. The amount of washing water required for cleaning is reduced to about one-fourth or less.

Moreover, since cleaning can be performed simply by rotating the barrel 7, automation can be easily performed, contributing to labor savings.

The object to be cleaned that has been cleaned is taken out from both lids 10.15, and a new object to be cleaned is put into the barrel 7 and cleaned again.

FIG. 3 is a flow sheet showing an example of a cleaning method using the cleaning apparatus of this embodiment. First, before cleaning the object to be cleaned using the cleaning device A, dirt that is relatively easily removed by the pre-washing device B is removed. Next, the prewashed object to be cleaned is cleaned using the main cleaning apparatus A. In this case, the degree of cleaning is determined by the type of item to be cleaned; for example, in the case of filter cloth, there is no problem in reusing it even if some dirt remains, whereas in the case of clothing, as long as it can be thoroughly washed. Try to remove filth. Washing water containing dirt used in this washing device A is supplied to a wastewater storage tank C equipped with a filter layer bag, and the washing water from which dirt has been filtered is discharged from the wastewater storage tank C. It is taken out of the system together with the prewash wastewater discharged from the prewash device B.

According to the method shown in FIG. 3, not only the amount of water required is reduced, but also cleaning water free of dirt can be collected in one place, which simplifies the process.

〔Effect of the invention〕

In the present invention, when cleaning an object to be cleaned, the object to be cleaned is housed in a cylindrical barrel having a required number of protrusions on the inner surface and a plurality of perforations around the periphery. The barrel is rotated and washed when less than half of the washing water is present. Therefore, since the object to be cleaned is washed in the washing water, the amount of washing water required is significantly reduced, unlike the conventional method. Moreover, compared to conventional methods, this method not only can remove dirt more efficiently in a shorter time, but also can be easily automated, and has the highest performance as a cleaning device.
