Description

  The present invention relates to a muddy material treatment tool, and more particularly, to a muddy material treatment device that can easily dehydrate the muddy material and can quickly transfer the muddy material after dehydration.

  Various methods have been proposed for dewatering muddy substances containing water such as turbid water and sludge generated at construction sites and floc obtained by agglomeration reaction of these (for example, see Patent Document 1). In Patent Document 1, a mud is stored in a water-permeable bag, and the mud is dehydrated by suspending the bag.

  Thus, in the method of directly suspending the bag body, since the bag body bears the entire load of the stored mud, the bag body needs to have an appropriate strength. It is effective to make the bag thinner to improve the water permeability in order to make the dehydration of the mud in a short time. However, if the bag is made thinner, it is disadvantageous to ensure the strength of the bag. Therefore, there has been a demand for another means and method that can easily dewater the mud. In addition, when the dewatered mud is discharged from the bag body and transferred to another place, the bag body needs to be turned upside down.

  An object of the present invention is to provide a muddy material treatment tool that can easily dehydrate muddy material and can quickly transfer the muddy material after dehydration.

  In order to achieve the above object, a sludge treatment tool of the present invention comprises a cylindrical container having water permeability that allows moisture of the mud to pass through, a closing member that closes a bottom opening of the container, and the container. And a bottomed cylindrical outer frame attached so that the bottom of the outer frame can be opened and closed.

  According to the mud processing apparatus of the present invention, a cylindrical container having a bottom opening closed by a closing member is attached to a bottomed cylindrical outer frame so that the mud is disposed in the container. Since the moisture contained in the mud flows out to the outside through the containing body only by housing the mud, the mud is dehydrated naturally. Since the container is inserted and held in the outer frame body, the strength to bear the load of the muddy material to be stored becomes unnecessary, and the specification mainly aimed at improving the dewatering performance can be achieved. Therefore, it is advantageous for shortening the dehydration time.

  After the dehydration of the mud is finished, the mud contained in the container is lifted and moved together with the outer frame, and the bottom of the outer frame is opened in the lifted state, and then closed. By opening the bottom of the container closed by the member, the mud contained in the container is discharged downward. Thereby, the mud after dehydration can be quickly transferred to a desired place.

  Here, for example, the specification is such that the wall surface of the outer frame body is formed in a mesh shape. According to this specification, it is possible to reduce the weight of the outer frame body and improve the dewaterability.

  It can also be set as the specification whose said closing member is a string-like material which has elasticity. According to this specification, the bottom opening of the container can be easily closed. Further, when the dewatered mud is discharged downward, the bottom of the container can be opened with the weight of the mud.

It is explanatory drawing which illustrates the muddy material processing tool which discharged | emitted the dehydrated muddy material below.

  The mud treatment tool of the present invention will be described based on the embodiment shown in the drawings.

  As illustrated in FIGS. 1 and 2, the mud treatment device 1 of the present invention includes a cylindrical container 2, a closing member 10, and a bottomed cylindrical outer frame 5. The container 2 has water permeability that allows the moisture of the mud S to be stored to pass through. The container 2 is formed of a flexible non-rigid material such as a cloth material (woven fabric or non-woven fabric), for example, and has a specification that hardly allows solids contained in the mud S to be accommodated. Yes.

  The closing member 10 is a member that closes the bottom opening 4 among the upper opening 3 and the bottom opening 4 of the container 2. The closing member 10 is preferably a string-like material having elasticity. For example, an annular rubber in which the string-like material is formed in an annular shape can be used. As described above, the closing member 10 may be a string-like material having at least a part of an elastic material such as rubber.

  The outer frame body 5 includes a through portion that penetrates the inside and outside of the outer frame body 5 at least in the vicinity of the bottom surface 7 or the bottom surface 7. The outer frame body 5 is higher in rigidity than the housing body 2 in order to bear the load of the mud S stored in the housing body 2 and is formed of a rigid material such as metal or hard resin. preferable. In this embodiment, the side surface 6 and the bottom surface 7 of the outer frame body 5 are formed in a mesh shape. The outer frame 5 is attached so that the container 2 with the bottom opening 4 closed is inserted. The bottom surface 7 of the outer frame body 5 is configured to be openable and closable. The mechanism that enables opening and closing of the bottom surface 7 is not particularly limited. In this embodiment, one end of the bottom surface 7 is attached to the lower end of the side surface 6 via a hinge 7a, and the bottom surface 7 rotates around the hinge 7a. By moving, the bottom surface 7 of the outer frame body 5 opens and closes.

  An open / close chain 9 is connected to the other end of the bottom surface 7, and an arbitrary position of the open / close chain 9 can be locked to the outer frame body 5. That is, by adjusting the position of the opening / closing chain 9 to be locked, the opening / closing and the opening / closing state of the bottom surface 7 can be adjusted. Instead of the opening / closing chain 9, another string-like body such as a wire or a rope may be used. A stopper member that engages and disengages the other end portion of the bottom surface 7 with the side surface 6 can also be used.

  A detachable frame-shaped fixing member 8 is attached to the upper edge of the outer frame body 5. The vicinity of the upper opening 3 of the container 2 attached so as to be inserted into the outer frame body 5 is sandwiched between the upper edge portion of the outer frame body 5 and the fixing member 8. Thereby, the vicinity of the upper opening 3 of the container 2 is fixed to the outer frame body 5. The fixing member 8 may have other specifications and structures as long as the vicinity of the upper opening 3 can be fixed to the outer frame body 5.

  The procedure for processing the mud using the mud processing tool 1 is as follows.

  First, as illustrated in FIG. 2, the container 2 having the bottom opening 4 closed by the closing member 10 is attached so as to be inserted into the outer frame 5. The bottom surface 7 of the outer frame 5 is kept closed.

  Next, as illustrated in FIG. 3, turbid water and sludge generated at a construction site or the like, and a mud S containing water such as floc obtained by agglomeration reaction of these from the upper opening 3 to the container 2 through a hose or the like. Input and contain.

  Since the moisture W of the mud S stored in the container 2 flows out through the container 2, the mud S is naturally dehydrated. Therefore, the mud S can be easily dehydrated. Here, since the container 2 is inserted and held in the outer frame body 5, the container 2 has an excessive strength for bearing the load of the mud S to be stored. It becomes unnecessary. Therefore, it is not necessary to adopt a specification such as increasing the film thickness of the container 2 in order to improve the strength, and it is possible to make the specification mainly intended to improve the dewatering performance. For example, minimizing the film thickness of the container 2 is advantageous for shortening the dehydration time.

  After the dehydration of the mud S has been left for a predetermined time, the mud S stored in the container 2 together with the outer frame 5 is lifted and moved to a desired location as illustrated in FIG. Let For example, the outer frame body 5 is lifted via the suspension wire 11 using a crane or the like and moved onto the transport vehicle 12.

  Next, the outer frame body 5 is temporarily placed on the loading platform of the transport vehicle 12, and the locking of the open / close chain 9 locked to the outer frame body 5 is released in a stable and safe state. As a result, the bottom surface 7 of the outer frame 5 can be rotated about the hinge 7a. Then, as illustrated in FIG. 5, the bottom surface 7 is opened with the outer frame body 5 being lifted.

  When the bottom surface 7 is opened, the bottom opening 4 of the container 2 closed by the closing member 10 is naturally opened by the weight of the mud S, and the dewatered mud S is discharged downward. The The mud S discharged on the transport vehicle 12 is transported by the transport vehicle 12.

  When discharging the mud S, there is no need to flip the bag body that had been storing the mud S as before, so the dewatered mud S can be quickly transferred to the desired location. it can. This container 2 can be used repeatedly until there is no major damage or it is clogged and the water permeability is significantly reduced.

  In this embodiment, since the closing member 10 is an elastic string-like material, the state where the bottom opening 4 by the closing member 10 is closed by the weight of the mud S is released simply by opening the bottom surface 7. It becomes possible to make it. Thus, it is desirable that the closing member 10 has a tightening force that releases the closed state of the bottom opening 4 by the weight of the dewatered mud S stored in the container 2. If the closed bottom opening 4 does not open due to the weight of the mud S, the closing member 10 is removed from the container 2 by manual work or the like.

  If the specification is such that the wall surface (side surface 6 and bottom surface 7) of the outer frame body 5 is formed in a mesh shape, it is advantageous for reducing the weight of the outer frame body 5. Further, since the moisture W passes through the mesh-shaped gap, it is advantageous to improve the dewaterability of the mud S. Only the bottom surface 7 of the outer frame 5 can be formed in a mesh shape.
