Summary of the Invention
Problems to be Solved by the Invention
[0004] By the way, there may be a need to further screen the light specific gravity objects discharged from the above-mentioned specific gravity difference separator. However, even in recent years, such screening work of light specific gravity objects may sometimes be performed manually.
[0005] An object of the present invention is to reduce the burden of screening work for light specific gravity objects discharged from a specific gravity difference separator.
Means for Solving the Problems
[0006] The sieving and recovery set according to the first aspect of the present invention comprises a sieving member and a recovery member. The sieving member is attached to the discharge port of the low specific gravity material in the specific gravity difference sorting machine. The recovery member is positioned below the sieving member to receive the low specific gravity material discharged from the discharge port. The sieving member has a perforated plate and a mounting part. The perforated plate is a plate having a plurality of openings and is inclined downward as it approaches the recovery member. The mounting part attaches the perforated plate to the aforementioned discharge port. The recovery member also comprises a first recovery container, a second recovery container and a non-perforated plate. The first recovery container is positioned below the lower end of the perforated plate. The second recovery container is positioned below the first recovery container. The non-perforated plate is positioned below the upper end of the perforated plate and is inclined downward as it approaches the second recovery container, extending to the second recovery container.
[0007] When a gravity differential separator is operated with a sieving member attached to the discharge port of low-density materials and a recovery member installed below the sieving member, the sieving member moves up and down in conjunction with the vertical movement of the gravity differential separator, sieving the low-density materials discharged from the discharge port of the gravity differential separator and moving them toward the recovery member. At this time, the low-density materials that pass through the perforations of the sieving member fall to the non-perforated plate of the recovery member and are then moved to the second recovery container by the non-perforated plate. On the other hand, the low-density materials that do not pass through the perforations of the sieving member (i.e., low-density materials with a particle size larger than the opening) continue to move along the perforated plate of the sieving member and fall into the first recovery container for collection. Therefore, this sieving and recovery set can automatically sieve the low-density materials discharged from the gravity differential separator, reducing the burden of sieving the low-density materials.
[0008] The sieving and collection set according to the second aspect of the present invention is the sieving and collection set according to the first aspect, wherein the collection member further has an inclined plate portion. The inclined plate portion is inclined upward as it approaches the inside of the first collection container. This inclined plate portion is disposed between the first collection container and the lower end of the perforated plate.
[0009] Therefore, it is possible to guide the low-density material falling from the perforated plate so that it falls into the first collection container. In addition, if there is a gap between the first collection container and the lower end of the perforated plate, the presence of this inclined plate section prevents the low-density material falling from the lower end of the perforated plate into the first collection container from bouncing off the bottom wall of the first collection container and flying out through the gap. [Brief explanation of the drawing]
[0010] [Figure 1] This is a front view showing a sieving and recovery set according to one embodiment of the present invention, with the sieving member attached to the low-density material discharge port of a density difference sorter, and the recovery member installed below the sieving member. [Figure 2] This is a perspective view of a perforated plate that constitutes a sieving member of a sieving and collection set according to one embodiment of the present invention. [Modes for carrying out the invention]
[0011] <Description of elements constituting the sieving and collection set according to an embodiment of the present invention> The sieving and collection set according to the embodiment of the present invention includes a sieving member and a collection member. These components will be described in detail below.
[0012] (1) Sieve member As shown in Figure 1, the sieving member 100 mainly consists of a mounting portion 110 and a perforated plate 120, and is attached to the discharge port EX of the specific gravity difference sorter SGD. In Figure 1, a pair of sieving members 100 are arranged on the left and right sides. Here, we will describe the sieving member 100 shown on the left side of Figure 1, and omit the description of the sieving member shown on the right side.
[0013] The mounting section 110 is a part for attaching the perforated plate 120 to the discharge port EX of the gravity differential separator SGD, and is formed from a front wall Wf and a rear wall (not shown). In other words, this mounting section 110 does not have a top wall, left side wall, right side wall, or bottom wall. The perforated plate 120 is welded to each wall of this mounting section 110. This mounting section 110 is attached to the discharge port EX of the gravity differential separator SGD using conventional fastening means such as screws.
[0014] The perforated plate 120 is, literally, a trough-shaped plate body having openings, and is formed from, for example, a plate body including perforated metal or wire mesh. Here, as shown in Figures 1 and 2, the perforated plate 120 is formed from a front plate Pf, a left side wall Pg, a rear wall Pr, a bottom wall Pb, and an inclined plate Ps. In other words, this perforated plate 120 does not have a top plate or a right side wall. Here, the front plate Pf, rear wall Pr, and bottom wall Pb are all formed from perforated metal or wire mesh. Also, here, as shown in Figure 1, the bottom wall Pb is inclined downward as it approaches the recovery member 200. The left side wall Pg and the inclined plate Ps are formed from non-perforated metal plates. The inclined plate Ps is inclined downward as it goes from the lower end edge of the left side wall Pg to the right (i.e., as it approaches the recovery member 200). As shown in Figure 2, the inclination angle of the inclined plate Ps in the horizontal direction is greater than the inclination angle of the bottom wall Pb.
[0015] (2) Recovery material As shown in Figure 1, the recovery member 200 mainly consists of a frame 210, a non-perforated inclined plate 220, a guide wall 230, a lower recovery container CN1, and an upper recovery container CNu. The lower recovery container CN1 and the upper recovery container CNu are detachable from the frame 210. These components will be described in detail below.
[0016] The frame 210 is a roughly rectangular parallelepiped frame, and as shown in Figure 1, it is formed from a top wall Wu, leg sections LG, and beam sections (not shown). The top wall Wu is a wall for detachably mounting the upper recovery container CNu. The leg sections LG extend downward from the four corners of the top wall Wu. The beam sections extend horizontally from a position near the lowest point of one leg section LG on the left side to a position near the lowest point of the other leg section LG on the left side, and also extend horizontally from a position near the lowest point of one leg section LG on the right side to a position near the lowest point of the other leg section LG on the right side. The lower recovery container CNl is detachably mounted on these left and right pairs of beam sections by being hooked onto them.
[0017] The non-perforated inclined plate 220 is a plate without openings and, as shown in Figure 1, is inclined upward as it moves away from the side of the frame 210. This non-perforated inclined plate 220 acts as a chute, receiving the low-density material falling from the perforated plate 120 and guiding it to the lower collection container CNl.
[0018] The guide wall 230 is a wall that guides the low-density material falling from the perforated plate 120 so that it falls into the upper recovery container CNu, and a pair of them are attached to the left and right sides of the top wall Wu of the frame 210. This guide wall 230 is formed from a vertical wall section 231 and an inclined wall section 232. The vertical wall section 231 extends upward from the top wall section Wu of the frame 210 as shown in Figure 1. The inclined wall section 232 is inclined upward from the upper end of the vertical wall section 231 toward the inside.
[0019] The lower recovery container CNl is a container having a tray shape, and its left and right edges are detachably placed on the lower side of the frame 210 in a manner that they are hooked on the beam portions of the frame 210. In addition, when the lower recovery container CNl is hooked on the beam portions of the frame 210 and the upper recovery container CNu is placed on the top wall portion Wu of the frame 210, the upper recovery container CNu exists above the lower recovery container CNl. Also, in a state where the lower recovery container CNl is hooked on the beam portions of the frame 210, the lower end of the non-perforated inclined plate 220 is located slightly above the upper end of the side wall of the lower recovery container CNl.
[0020] The upper recovery container CNu is a container having a tray shape similar to the lower recovery container CNl, and is detachably placed on the top wall portion Wu of the frame 210. In addition, in a state where the upper recovery container CNu is placed on the top wall portion Wu of the frame 210, the lower end portion of the perforated plate 120 of the sieve member 100 is located above the upper recovery container CNu.
[0021] <Usage and Function of the Screening and Recovery Set According to the Embodiment of the Present Invention> The usage of the above-described screening and recovery set is as follows. First, as shown in FIG. 1, the sieve member 100 is attached to the discharge port EX of the light specific gravity material in the specific gravity difference separator SGD, and the recovery member 200 is installed below the sieve member 100. In this state, when the specific gravity difference separator SGD is operated, the sieve member 100 moves up and down in conjunction with the up and down movement of the specific gravity difference separator SGD, and moves the light specific gravity material discharged from the discharge port EX of the specific gravity difference separator SGD toward the recovery member 200 while sieving it. At this time, the light specific gravity material passing through the apertures of the perforated plate 120 of the sieve member 100 falls to the non-perforated inclined plate 220 of the recovery member 200 and is then moved to the lower recovery container CNl by the non-perforated inclined plate 220. On the other hand, the light specific gravity material that does not pass through the apertures of the perforated plate 120 of the sieve member 100 (that is, the light specific gravity material having a particle size larger than the apertures) moves on the perforated plate 120 of the sieve member 100 as it is and falls into the upper recovery container CNu for accommodation.
[0022] <Features of the Screening and Recovery Set According to the Embodiment of the Present Invention> In the screening and recovery set according to the embodiment of the present invention, the light specific gravity materials discharged from the specific gravity difference separator SGD can be automatically screened, and the burden of the screening work of the light specific gravity materials can be reduced.
[0023] <Modified Example> (A) In the perforated plate 120 of the screening member 100 according to the previous embodiment, the front plate portion Pf, the rear wall portion Pr, and the bottom wall portion Pb were all formed from punching metal, wire mesh, etc. However, only the bottom wall portion Pb may be formed from punching metal, wire mesh, etc., and the front plate portion Pf and the rear wall portion Pr may be formed from a non-perforated plate.
[0024] (B) The frame 210 of the recovery member 200 according to the previous embodiment was a substantially rectangular parallelepiped-shaped frame, but the shape of the frame 210 is not particularly limited, and it may be a frame such as a cylindrical shape or a polyhedron shape.
[0025] (C) The top wall portion Wu of the frame 210 of the recovery member 200 according to the previous embodiment may be a corner frame.
[0026] (D) The upper recovery container CNu and the lower recovery container CNl of the recovery member 200 according to the previous embodiment had a tray shape, but the shapes of the above-mentioned recovery containers CNu and CNl are not particularly limited, and they may have other shapes.
[0027] (E) In the previous embodiment, the screening and recovery set was applied to the specific gravity difference separator SGD having two light specific gravity material discharge ports EX. However, the screening and recovery set according to the previous embodiment may be applied to the specific gravity difference separator SGD having one or three or more light specific gravity material discharge ports EX.
[0028] Note that the above-mentioned modified examples may be applied alone or in combination.
