Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, even in recent years, in the metal manufacturing site, the above sieving may be performed manually.

[0005] An object of the present invention is to reduce the burden of sieving work at the metal manufacturing site.

Means for Solving the Problems

[0006] The rotary sieve according to the first aspect of the present invention includes a container body and a shaft body. In the container body, a plurality of openings are formed in its container wall. The shaft body pivotally supports the container body so as to be rotatable.

[0007] Therefore, by rotating the container body around the shaft body, sieving of metal pulverized materials and the like can be performed. Therefore, this rotary sieve can reduce the burden of sieving work at the metal manufacturing site.

[0008] The rotary sieve divider according to the first aspect of the present invention further comprises a handle. The handle is attached to the container or shaft so as to extend outward from the outer surface of the container or from the end of the shaft.

[0009] The sieving operator can rotate the container by turning the handle. Therefore, this rotary sieving machine can further reduce the burden of sieving work in metal manufacturing plants.

[0010] The rotary sieve divider according to the first aspect of the present invention further comprises a magnet. The magnet is attached to the wall of the container. Preferably, the magnet is fixed to the inner surface of the wall of the container.

[0011] Therefore, in this rotary sieve separator, if a magnetic metal is present in a non-magnetic metal, the magnetic metal can be selectively removed from the non-magnetic metal using a magnet. [Brief explanation of the drawing]

[0012] [Figure 1] This is a side view of a rotary sieve divider according to one embodiment of the present invention. [Figure 2] This is a front view of a rotary sieve divider according to one embodiment of the present invention. [Figure 3] This is a side view showing the state in which the sieving container 120 and the shaft 130 are mounted on the frame in a rotary sieving device according to one embodiment of the present invention. [Modes for carrying out the invention]

[0013] <Structure of a rotary sieve according to an embodiment of the present invention> The rotary sieve separator 100 according to an embodiment of the present invention is a device for sieving lumpy materials such as sponge titanium, and for removing or separating relatively small magnetic materials that may be present in the lumpy materials (for example, magnetic powder such as rust fragments or magnetic particles of 10 mm or less). It mainly consists of a frame 110, a sieving container 120, a shaft 130, and a handle 140. These components will be described in detail below.

[0014] (1) Frame As shown in Figures 1 and 2, the frame 110 is a truncated pyramidal frame that supports the sieving container 120 via the shaft 130. When in use, the frame 110 is placed on top of the collection container CTN as shown in Figures 1 and 2. As shown in Figure 3, a roughly semicircular notch RC is formed in the upper beam BM of the frame 110 in a side view. This notch RC is used as a space to receive the shaft 130. The frame 110 is also fitted with a sliding shaft stopper 150 and a rotation stopper 160 as shown in Figures 1 to 3. The sliding shaft stopper 150 is a rod-shaped sliding body that, when the shaft 130 is not received in the notch RC, is positioned to the side of the notch RC to leave space above the notch RC, and when the shaft 130 is received, slides onto the notch RC to prevent the shaft 130 from coming out of the notch RC. The rotation stopper 160 is also a rod-shaped sliding body. When it is desired to stop the rotation of the sieving container 120, it is slid to enter the holes in the perforated metal on the side of the sieving container 120. When it is desired to rotate the sieving container 120, it is slid to exit the holes in the perforated metal on the side of the sieving container 120.

[0015] (2) Sieving container As shown in Figures 1 and 2, the sieving container 120 is a roughly rectangular box-shaped body supported by a shaft 130. As shown in Figure 1, both sides of the sieving container 120 are made of perforated metal. As shown in Figure 2, the front, back, top, and bottom surfaces of the sieving container 120 are made of wire mesh. As shown in Figure 2, an opening is formed in the wire mesh on the front, and a door DR is attached to cover this opening. This door DR is also made of wire mesh. As shown in Figure 2, magnets MGo and MGq are detachably attached to the inner surface of the wire mesh on the bottom. These magnets MGo and MGq are permanent magnets. As shown in Figure 2, magnet MGo is annular in shape, and magnet MGq is fan-shaped.

[0016] (3) Shaft The shaft 130 extends outward from the side of the sieving container 120 along a line connecting the points where the diagonals of opposite sides of the sieving container 120 intersect, and pivotally supports the sieving container 120 so that it can rotate. As described above, this shaft 130 is integrated with the sieving container 120 and can be removed from the frame 110 together with the sieving container 120.

[0017] (4) Handle section The handle portion 140 is a crank-shaped part that extends outward from the end of the shaft 130 in a direction parallel to the axial direction, then extends radially, and then extends outward again in a direction parallel to the axial direction, and is attached to the sieving container 120 via the shaft 130. The operator can rotate the sieving container 120 by rotating this handle portion 140 around the shaft.

[0018] <How to use the rotary sieve according to the embodiment of this invention> The above-mentioned rotary sieve divider is used as follows: First, a sieving container 120 with magnets MGo and MGq fixed to its inner surface is placed on a recovery container CTN via a frame 110. Next, the sieving container 120 is rotated and stopped with the surface having the door DR facing upward. Next, the door DR is opened, metal pulverized materials, etc. are put into the sieving container 120, and then the door DR is closed. Then, the handle part 140 is turned to rotate the sieving container 120 around the shaft body 130, and the metal pulverized materials, etc. that pass through the mesh of the sieving container 120 are dropped into the recovery container CTN. In this case, it is preferable to increase the rotation speed as the size of the pulverized material is larger. When the sieving is completed, the sieving container 120 is rotated and stopped with the surface having the door DR facing upward, the door DR is opened, the magnets MGo and MGq are removed, and the magnetic substances adhering to those magnets MGo and MGq are wiped off to recover the magnetic substances. After that, the sieving container 120 is removed, and the metal pulverized materials, etc. remaining in the sieving container 120 are transferred to another recovery container.

[0019] <Features of the Rotary Siever According to the Embodiment of the Present Invention> In the rotary siever 100 according to the embodiment of the present invention, by rotating the sieving container 120 around the shaft body 130 via the handle part 140, sieving of metal pulverized materials, etc. can be performed, and when magnetic metal is contained in non-magnetic metal, the magnetic metal can be selectively removed from the non-magnetic metal by the magnets MGo and MGq. Therefore, this rotary siever can reduce the burden of sieving and magnetic separation operations at the metal manufacturing site.

[0020] <Modification Example> (A) In the rotary siever 100 according to the previous embodiment, the sieving container 120 was substantially rectangular parallelepiped, but this sieving container 120 may be a cylinder or a polygonal prism. In such a case, the shaft body 130 will be attached or inserted along the axis of these prisms.

[0021] (B) In the rotary sieving separator 100 according to the above embodiment, both sides of the sieving container 120 are made of perforated metal, and the front, back, top, and bottom surfaces are made of wire mesh. However, all surfaces may be made of perforated metal, all surfaces may be made of wire mesh, or both sides may be made of wire mesh and the front, back, top, and bottom surfaces may be made of perforated metal. Alternatively, one of the front, back, top, and bottom surfaces may be made of perforated metal and the remaining surface may be made of wire mesh.

[0022] (C) In the rotary sieve divider 100 according to the previous embodiment, the shaft 130 was integrated with the sieving container 120, but the shaft may be separate from the sieving container 120. In this case, it is necessary to form a through hole in the sieving container 120 for inserting the shaft, and to attach the handle portion 140 to the sieving container 120.

[0023] (D) In the rotary sieve divider 100 according to the previous embodiment, the handle portion 140 was attached to the sieve container 120 via the shaft 130, but the handle portion 140 may be attached to the sieve container 120.

[0024] (E) In the rotary sieve divider 100 according to the previous embodiment, permanent magnets were used as magnets MGo and MGq, but electromagnets may be used instead of permanent magnets.

[0025] (F) In the rotary sieve separator 100 according to the above embodiment, an annular magnet MGo and a fan-shaped magnet MGq were used as magnets, but the shape of the magnets is not particularly limited, and may be, for example, a sheet, a rod, or any other shape. If the shape of the magnets is a sheet, the entire bottom surface of the sieve container 120 may be covered with a magnetic sheet. Alternatively, a magnetic sheet may be attached to the inner surface of the door DR.

[0026] (G) In the rotary sieve divider 100 according to the previous embodiment, magnets MGo and MGq were fixed to the inner surface of the wire mesh forming the bottom surface of the sieve container 120. However, magnets MGo and MGq may be fixed to the outer surface of the wire mesh forming the bottom surface of the sieve container 120.

[0027] (H) In the rotary sieve divider 100 according to the previous embodiment, two magnets MGo and MGq were used, but the number of magnets is not particularly limited and may be one or three or more.

[0028] (I) In the rotary sieve separator 100 according to the above embodiment, magnets MGo and MGq were fixed to the sieve container 120, but these magnets MGo and MG may be omitted if magnetic separation is not required.

[0029] (J) In the rotary sieve divider 100 according to the previous embodiment, magnets MGo and MGq were fixed to the inner surface of the wire mesh forming the bottom surface of the sieve container 120, and a door DR was attached to the wire mesh forming the front surface. However, there are no particular restrictions on the fixing surface of the magnets MGo and MGq or the mounting surface of the door DR; they can be fixed or attached to the wire mesh forming any surface.

[0030] (K) In the rotary sieve divider 100 according to the above embodiment, a handle portion 140 was attached to the sieve container 120, but the handle portion 140 may be omitted.

[0031] (L) In the rotary sieving divider 100 according to the above embodiment, a handle 140 is attached to the sieving container 120, and the sieving container 120 is rotated by turning the handle 140 manually. However, an electric motor or engine may be attached to the shaft 130, and the sieving container 120 may be rotated by electricity or fuel.

[0032] (M) In the rotary sieve divider 100 according to the previous embodiment, the sliding shaft stopper 150 was a screw-type sliding body, but it may also be a spring-type sliding body. In such a case, the sliding shaft stopper 150 is usually positioned on the notch RC, and before inserting the shaft 130 into the notch RC, or before removing the shaft 130 from the notch RC, the sliding shaft stopper 150 is moved laterally against the biasing force of the spring, and after inserting the shaft 130 into the notch RC, and after removing the shaft 130 from the notch RC, the sliding shaft stopper 150 is released and returned to its initial position (i.e., on the notch RC).

[0033] (N) In the rotary sieving device 100 according to the previous embodiment, the rotation stopper 160 was a screw-type sliding body, but it may also be a spring-type sliding body. In this case, the rotation stopper 160 is normally inserted into the holes of the perforated metal on the side of the sieving container 120, and when it is desired to rotate the sieving container 120, the rotation stopper 160 is pulled out of the holes of the perforated metal against the biasing force of the spring, and the rotation stopper 160 is fixed in that state with a fixing device. When it is desired to stop the rotation of the sieving container 120, the rotation stopper 160 is released from the fixing device and returned to its initial state (i.e., inserted into the holes of the perforated metal on the side of the sieving container 120).

[0034] The above modifications may be applied individually or in combination. [Industrial applicability]

[0035] The rotary sieving device according to this invention has the advantage of reducing the burden of sieving work in metal manufacturing sites, and can be used in metal manufacturing sites and the like. [Explanation of Symbols]
