Description

  The present invention relates to a rolling-out device, and more particularly, to a rolling-out device provided with a chute.

The construction of improving and purifying the quality of seawater by applying sand and covering sand on the soft ground of the seabed to contain soft ground such as sludge layer has been performed. Recently, in order to restore the lost natural environment, construction work has been undertaken to create tidal flats by putting earth and sand into the seabed. There are various methods for these works. For example, there is a direct opening method in which sand is thrown into the sea floor using a bottom open purge, a crane ship's clam shell, a swing method using a belt conveyor, a water carrying method using a micropump, and a tremy method (patented) Reference 1).
JP 2000-136533 A

  However, the conventional method has the following problems.

  In the direct injection method, sand is introduced from above the sea surface toward the sea bottom, so if the sea bottom is soft ground, the sea bottom will be destroyed. For this reason, the direct injection method is not suitable for applying sand or covering sand to soft ground.

  In the swing method, sand is spread while the belt conveyor is swung from side to side, but the construction width in one swing is narrowed. Therefore, in order to spread the sand in a certain area, the belt conveyor must be swung several times. However, if the belt conveyor is swung several times, the bottom of the sea where the sand is sown at each swing or once It will be dotted with places where only sand is sown. Therefore, with the swing method, it is difficult to lay sand of uniform thickness on the seabed.

  In the water carrying method and the tremy method, sand is spread using a water flow, so that it is difficult to spread sand in a certain range, and therefore it is difficult to spread sand having a uniform thickness on the seabed.

  This invention is made | formed in view of this point, The place made into the objective is to provide the brewing apparatus which can spread | solidify a solid substance on the ground substantially uniformly thinly.

The present invention is a brewing device that spreads solids supplied from a supply device on the ground. This device is provided with a plate-like chute that is arranged to be inclined with respect to the vertical direction, and the solid material is supplied from the supply device to the surface of the chute. On the surface of the chute, there is a shortest path area so as to connect the portion to which the solid material is supplied to the lower end of the chute with the shortest distance. Further, a curved region exists in a part of the chute in the vertical direction so as to extend in the horizontal direction of the chute. In the curved region, the chute is bent so as to protrude upward in the vertical direction, and the apex located most vertically upward in the curved region exists in the shortest path region in the curved region. A position changing unit for changing the position of the vertex in the vertical direction is provided below the apex of the curved area of the chute, and the positions of the right end and the left end are changed below the right end and the left end of the curved area of the chute. An inclination angle changing unit for changing the inclination angle of the chute is provided.

Maki out device of the present invention, in the preferred embodiment described below, position changing unit includes a jack, jack, the back surface side of the apex of the curved area, is pressed vertically upward. With such a configuration, the shape of the chute can be set to an optimum shape according to the physical properties of the solid matter, the construction situation, and the like.

Also in a preferred embodiment described later, inclination oblique angle changing unit includes a hinge, the hinge rotates the chute as the pivot center to the upper end of the chute. With such a configuration, the inclination angle can be optimized according to the physical properties of the solid, the construction status, and the like.

In certain embodiments of the discussed later, supply device is a hopper, the solids are supplied from the supply port of the hopper to the surface of the chute.

  In the present invention, it is possible to spread the solid material on the ground substantially uniformly and thinly.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the following embodiment.

Embodiment 1 of the Invention
In the first embodiment, the configuration and operation of the brewing device will be described by taking a brewing device used when pulverizing the coal ash granule on the seabed as an example.

  At the time of start-up, the start-up device according to the present embodiment is fixed on a trolley (not shown), and the coal ash granule is sprinkled on the seabed while moving the trolley. Thereby, coal ash granulated material can be spread over a wide range on the seabed.

  The coal ash granulated material to be sown on the sea bottom is a mixture of about 85% coal ash and about 15% cement, which is preferably solidified. Such a coal ash granule has a smaller specific gravity than sand. Therefore, compared with the case where sand is thrown in, the impact given to the seabed at the time of throwing can be made small.

  FIG. 1 is a cross-sectional view showing a configuration of a scooping device S1 according to the present embodiment.

  This soaking apparatus S1 includes a chute 11. The chute 11 is a plate-like member as shown in FIG. 1, and is arranged inclined from the vertical direction. Then, the coal ash granules 1, 1,... Are supplied from a supply device (not shown) to the surface 11a of the chute, fall along the surface 11a of the chute, and are spread on the seabed. Thereby, even if it is a soft ground, coal ash granulated material 1,1, ... can be sprinkled on the seabed, without destroying the ground.

  FIG. 2 is a diagram showing the configuration of the chute 11 according to the present embodiment, FIG. 2 (a) is a plan view showing the configuration of the surface, and FIG. 2 (b) is a view of the chute 11 from the lower end side. It is a top view at the time.

  The chute 11 will be described in detail. The outer shape of the chute 11 is a trapezoid, and the lower end is wider than the upper end. Further, as shown in FIG. 2A, the shortest path region 13 and the curved region 15 exist on the surface 11a of the chute. The shortest path region 13 is a region where the portion 13a to which the coal ash granule is supplied is connected to the lower end of the chute at the shortest distance. Although the part 13a to which the coal ash granulated material is supplied is not particularly limited, it is preferably closer to the upper end than the position at which the chute 11 is divided in the vertical direction. It preferably exists so as to extend in the left-right direction.

  The curved region 15 exists around the lower end of the chute 11 and extends in the left-right direction of the chute 11. When the curved region 15 is observed from the lower end side of the chute 11, as shown in FIG. 2 (b), the curved region 15 is bent in a bow so as to protrude vertically upward, and the vertex 15a is the shortest path region. 13 is present. In other words, when the curved region 15 is observed from the lower end side of the chute 11, the substantially middle point (vertex 15a) in the left-right direction of the chute 11 is located at the uppermost vertical position, and from the substantially middle point (vertex 15a) to the left end and As it goes to the right end 15b, it is gradually positioned vertically downward. Since such a curved region 15 is formed in the chute 11, unlike the case where the rolling device is provided with a flat chute, the coal ash granulated material 1, 1,. be able to. The reason is as follows.

  When the chute is a flat plate, most of the coal ash granule falls through the shortest path area to the lower end of the chute and is drowned on the seabed. Therefore, it is difficult to thinly pulverize the coal ash granulated material over a wide range using such a brewing apparatus.

  On the other hand, in the chute 11 according to the present embodiment, when the coal ash granule 1, 1,... Travels through the shortest path region 13, the coal ash granule 1, 1,. In order to pass through the vertex 15a, the potential energy for passing through the vertex 15a is required. Therefore, it is unlikely that all the supplied coal ash granules 1, 1,... Pass through the shortest path region 13 to the lower end, and some of the coal ash granules 1, 1,. It progresses diagonally downward from the made part 13a. That is, the coal ash granules 1, 1,... Advance to the lower end of the chute 11 while spreading in the left-right direction of the chute 11 in the curved region 15. As a result, the coal ash granules 1, 1,... Can be diffused and spread on the seabed.

  The position of the vertex 15a in the vertical direction can be changed by the position changing unit P1 shown in FIG. FIG. 3 shows the configuration of the position changing unit P1.

  The position changing part P1 is provided on the back side of the vertex 15a and has a jack 20. The jack 20 is inserted into the insertion port 30a of the holding member 30 with play. The loose member 30 may be connected to a fixing member (not shown) for fixing the lifting device S1 to the trolley, or may be a part of the fixing member.

  The jack 20 is a member that applies an external force in a direction substantially perpendicular to the chute surface 11a from the back surface side of the apex 15a. The fixing member 21, the hinge 23, the bolt 25, the handle 27, the ball bearing 29, and the like. have. The fixing member 21 is fixed to the back surface side of the vertex 15 a and is connected to the bolt 25 via the hinge 23. The bolt 25 extends in a direction substantially perpendicular to the surface 11a of the chute, and a nut 27a of the handle 27 is screwed to the bolt 25. A ball bearing 29 is provided below the handle 27, and the ball bearing 29 is in contact with the flange 31.

  In such a position changing portion P1, when the handle 27 is rotated, the bolt 25 moves up and down in a direction substantially perpendicular to the surface 11a of the chute, and as a result, the bolt 25 extending upward from the handle 27. (Hereinafter referred to as “the length above the bolt 25”) becomes longer or shorter. As the length above the bolt 25 becomes longer, the lower end of the chute 11 is bent like a bow so as to protrude further upward, and thus the vertex 15a is further arranged vertically upward. On the other hand, as the length above the bolt 25 becomes shorter, the bow of the lower end of the chute 11 becomes gentler, and thus the vertex 15a is arranged slightly closer to the vertically lower side. That is, in the position changing unit, the position of the vertex 15a in the vertical direction can be changed by rotating the handle 27.

  Further, when the bow of the lower end of the chute 11 changes due to the change in the length above the bolt 25, the inclination of the bolt 25 slightly changes. However, since the ball bearing 29 is in contact with the flange 31, the jack 20 Release of play can be prevented.

  Since the brewing device S1 has such a position changing part P1, the shape of the chute 11 can be changed to an optimum shape according to the physical properties of the coal ash granulated material 1, 1,. it can. Although the position of the vertex 15a in the vertical direction depends on the drying condition and size of the coal ash granulated material 1, 1,..., The construction time, the construction amount, etc., it cannot be said unconditionally, but the vertex 15a, the left end, and the right end The distance in the vertical direction with respect to 15b is preferably 400 mm or less, and more preferably 200 mm or more and 400 mm or less. More specifically, the relationship between the distance and the physical properties of the coal ash granulated material 1, 1,..., When the coal ash granulated material 1, 1,. Since the dropping speed of the granules 1, 1,... Increases, this distance is preferably about 400 mm. On the other hand, when the coal ash granules 1, 1,... Are large or slightly wet, the falling speed of the coal ash granules 1, 1,. is there.

  Furthermore, the chute 11 includes an inclination angle changing part P2. FIG. 4 is a diagram showing the configuration of the tilt angle changing portion P2, and the tilt angle changing portion P2 is provided on the back side of the left end and the right end 15b at the lower end of the chute 11, and the tilt angle of the chute 11 with respect to the vertical direction. To change. Specifically, the inclination angle changing unit P <b> 2 includes a hinge 17 and a jack 20. The hinge 17 rotates the chute 11 around the upper end of the chute 11 as a rotation center. The jack 20 has substantially the same configuration as the jack 20 in the position changing portion P <b> 1, but is inserted into the insertion port 40 a of the insertion member 40. The fitting member 40 may be connected to a fixing member for fixing the starting device S1 to the carriage, or may be a part of the fixing member.

  In such an inclination angle changing part P2, the chute 11 can be rotated around the upper end of the chute 11 by the hinge 17, and the chute 11 after the rotation can be stably arranged by the jack 20. . Specifically, when the inclination angle of the chute 11 with respect to the vertical direction is increased, the length above the bolt 25 may be increased, and when the inclination angle with respect to the vertical direction is decreased, the length above the bolt 25 may be decreased. Although this inclination angle is not unconditional because it depends on the drying condition and size of the coal ash granulated product, the construction time, the construction amount, etc., it is preferably 50 ° or more and 70 ° or less, more preferably It is about 60 °. More specifically, the relationship between the inclination angle and the physical properties of the coal ash granulated material 1, 1,..., When the coal ash granulated material 1, 1,. The angle may be about 70 °. On the other hand, when the coal ash granulated material 1, 1,... Is large or wet, the falling speed of the coal ash granulated material cannot be sufficiently increased when the inclination angle is about 70 °. It is preferable to make the angle smaller than 70 °.

  As described above, in the brewing apparatus S1 according to the present embodiment, the coal ash granulated material 1, 1,... Falls along the surface 11a of the chute and is supplied to the seabed. It is possible to supply coal ash granules 1, 1, ... to the sea floor without breaking the ground. Moreover, since the curved area | region 15 is formed in the surface 11a of a chute | shoot, coal ash granulated material 1,1, ... can be supplied thinly to the seabed in a wide range. Furthermore, since it has the position change part P1 and the inclination angle change part P2, according to the physical property and construction condition of coal ash granulated material 1,1, ..., the shape of a chute can be made into an optimal shape. .

  The hopper 51 is an example of a supply device, and temporarily stores the coal ash granules 1, 1,... And supplies the coal ash granules 1, 1,. The chute 11 is disposed below the supply port 52 of the hopper 51. The supply port 52 is substantially rectangular when viewed from above, and the supply port 52 is provided with first and second rotating shafts 53 and 54 extending in the longitudinal direction of the supply port 12. And the coal ash granule 1, 1, ... can be supplied to the chute | shoot 11 by rotating the 1st rotating shaft 53 and the 2nd rotating shaft 54 in the opposite direction mutually.
