Previously, the use of filter cloth for separation of water from mixtures of solids and water has been well known.
Further, packaging or transporting bags made of 15 polyethylene or polypropylene cloth and provided with reinforcing belts and hanging belts or ropes have previously been known for delivery packaging.
However, the conventional dewatering filter cloth is used only for dehydration (removal of water), and the 20 conventional packaging or transporting bags are used only for packaging'or only for transportation. It is therefore desired to develop a container not limited to one use, such as a dewatering bag which can be used for dehydrating, e: packaging, transporting and storing operations, or a transporting bag which can be used for packaging, transporting and storing.
SUMMARY OF THE INVENTION It is the object of the present invention to overcome or substantially ameliorate the above disadvantages.
There is disclosed herein a container for dewatering and for packaging and transportation comprising: an inner cloth container for removing water from a wet mixture to form a powdery or granular substance and for packaging said powdery or granular substance, which container has a mouth portion; and an outer net-like container for containing said inner container at least during dewatering, said outer container comprising an opening and a hanging member at an upper portion thereof and an easy-to-open-and-shut closure at a bottom portion thereof for removing the inner container.
BRIEF DESCRIPTION OF THE DRAWINGS A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings, wherein: Fig. 1 is a schematic perspective view showing a net-like bag in the opened state forming an external container used in the present invention; Fig. 2 is a schematic perspective view showing a net-like bag in the closed state forming an external container used in the present invention; 20 Fig. 3 is a schematic perspective view showing an inner bag in the opened oooe• state forming an internal container used in the present invention; Fig. 4 is a schematic perspective view showing an inner bag in the closed state forming an internal container used in the present invention; Fig. 5 is a schemati )erspective view showing an *o 3 embodiment of the present invention in the state in which an alner bag forming an internal container is inserted into a net-like bag forming an external container; Fig. 6 is a schematic perspective view showing another embodiment of the present invention in the state in which an inner bag forming an internal container is inserted into a net-like bag forming an external container; Fig. 7 is a schematic perspective view showing a container of the present invention in which a basket-like container is used as an external container; and Fig. 8 is an exploded view showing a unit for assembling the basket-like external container.
ooue S"DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, the external container may oeooo S 15 be cylindrical, and particularly a circular or polygonal cylindrical net br. Further, the external container may be a basket-like article such as a woven basket or a e plastic basket. The external container is provided with the hanging member at the upper portion thereof. Any hanging member may be used. Polyester or polyamide ropes S"are usually employed. The external container is further provided with the closure at the bottom portion thereof.
The closure is closed during removal of water or packaging to hold the internal container, and opened after termination of dewatering or packaging to take out the internal container, which is then subjected to transportation. In the case of the net-like external 4 container, it may be netted of high tenacity yarn, for example, synthetic yarn such as polyamide yarn or polyester yarn. In some cases, the net-like external container may be netted of another material such as bamboo or may be formed of a synthetic resin.
The internal container is a cylindrical cloth container having a bottom suited to the external container, for example, a bag, and is provided with a closure at a mouth portion thereof. The closure may be anything as long as they are easy-to-shut and open, and it includes a rope, a string, and a belt. The internal container for dewatering is usually formed of a cloth knitted of synthetic yarn or filaments or a non-woven fabric of synthetic fibers. Textile fabrics for civil engineering S 15 works, non-woven fabrics of polypropylene filaments, etc.
are used for this purpose. For packaging a powdery or granular substance, any of the materials which have been usually employed may be used. The internal container may be formed of a disintegrable or corrosible material. When the inner bag is used for dewatering of sludge, it is preferred to use the disintegrable or corrosible bag which is resolved into soil by placing it in soil for a long period of time. The disintegrable or corrosible internal container may be made of a disintegrable synthetic resin or cotton.
The container of the present invention is preferably used for dewatering wet mixtures, and then for packaging, 5 transporting and storing the dehydrated solids.
The wet mixture may be any one. In particular, the container of the present invention can be preferably used to remove water from sludge, deposited on the bottom of a lake, a river or the sea, or industrial drain. For example, the container of the present invention can be used for treating wet mixtures obtained by introducing separating coagulants into sludge or industrial drain to render the sludge to be hydrophobic for separation.
Examples of the separating coagulants include aqueous solutions mainly containing divalent or trivalent iron salts, trivalent metal salts or alkaline earth metal salts.
The divalent or trivalent iron salts include ferrous sulfate, ferric sulfate and ferric chloride. The trivalent metal salts include aluminum sulfate [Al 2 (S04) 3 and aluminum potassium sulfate [AlK(S0 4 3 The alkaline earth metal salts include magnesium chloride (MgC12 6H 2 0) and calcium chloride (CaCI 2 The container of the present invention comprises the 20 external container and the internal container, for example, the outer bag and the inner bag, and it become possible to conduct dewatering, packaging, transportation and storage co*e by changing only the inner b-,g.
Embodiments of the present invention are hereinafter described by reference to the drawings.
Example 1 Referring to Figs. 1 to 7, an outer bag 1 is a 6 circular cylindrical net bag netted of polyamide yarn, and is provided with a hanging belt or belts 2, a hanging member, at its upper portion and with a closing string 3, a closure, at its bottom portion. Fig. 1 shows a state in which the outer bag is open, and Fig. 2 shows a state in which the outer bag is closed In Figs. 1 and 5, the hanging belt or belts 2 are attached to a leading edge portion of the bag 1. However, the hanging belt 2 may be attached between the leading edge portion and an intermediate portion of the bag as shown in Fig. 6.
For the materials of the outer bag, a main body, the upper portion and the bottom portion of the outer bag is formed of a polyamide net, the hanging member (a rope or ropes) and ropes vertically and laterally arranged on the 15 net are made of a polyester, and the closure (rope) is made of a polyamide.
An inner bag 4 is placed in the outer bag 1, and has a form suited thereto such as a circular cylindrical form or another polygonal cylindrical form. The inner bag 4 is 20 provided with a closing string 5 at its mouth portion.
Fig. 3 shows a state in which the inner bag is opened, and Fig. 4 shows a state in which the inner bag is closed. The inner bag may be formed of a non-woven fabric or a knitted fabric of a disintegrable or corrosible synthetic resin or cotton. Such an inner bag is used when it is desired to disintegrate or corrode by allowing it to stand for a long period of time.
7 When wet mixtures obtained by treating sludge with separating coagulants are dewatered, or powdery or granular substances are packaged, the inner bag 4 is placed in the outer bag 1, and the closure 3 attached to the bottom portion of the outer bag 1 is closed, as shown in Figs. and 6. Hanging the outer bag 4 by use of the hanging belts 2, the wet mixtures or the powdery or granular substances are introduced into the inner bag 4 through the mouth portion thereof. Water contained in the wet mixtures is removed through the inner container and the outer container. After completion of dewatering or packaging, the bottom portion of the outer bag 1 is opened, and the S"inner bag 4 is taken out of the outer bag i. Then, the inner bag 4 is transported or stored. The new inner bag 4 rooeoo is placed in the outer bag 1, and the above-described operations are repeated.
.e Example 2 Fig. 7 shows another embodiment of the present invention, in which an external container is in the form of S 20 a basket. This external container can be assembled by e eo S"fitting several units made of a synthetic resin shown in Fig. 8 to each other at the positions of connecting portions 6 and inserting connecting rods 7 into the connecting portions 6. Yn the external container, the reference numeral 8 designates fixing elements for ropes, and the reference numeral 9 designates elongated hollow portions in which closures 3 or closing strings are 8 inserted.
An internal container 4 is formed like that of Example 1. By using this external basket-like container, dewatering of wet mixtures or packaging of powdery or granular substances, transportation and storage can be easily carried out in a manner similar to that of Example 1.
According to the present invention, it is possible to constitute a system for dewatering wet mixtures in the internal container placed in the external container or packaging powdery or granular substances in the internal container, and transporting and storing only the internal Scontainer. Accordingly, these dewatering or packaging, transporting and storing operations can be very easily achieved.
