Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for screening granules such as heather used in a trundle mill or the like using a screening screen.

Conventionally, in order to sieve beads (mainly glass beads), which are small spherical media used in sand mills, etc., these materials to be sorted are shaken! They were placed on a mesh or slanted slit and separated into those that passed through the net 131 or the sleeve 1- and those that remained.

However, with this method, meshes, etc. often become clogged, and in the case of spherical objects such as glass beads with a diameter of 31111 or less, meshes, slits, etc. There were many cases where only 1 to 10 pieces were passed, and there was a drawback that the efficiency of sorting was poor.

The present invention has been made in view of the above points, and it is an object of the present invention to provide an efficient sorting device that prevents clogging and eliminates splashing from the mesh material such as beads.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic front view showing a vertical cross section of the sorting device.

In the figure, (1) is a panel-shaped particle sorting screen as shown in the partial perspective view of FIG. (1b) and is composed of a large number of parallel slits, which are arranged approximately horizontally inside the device so that the slits face from the inlet side to the outlet side of the particles. In addition, the example shown in FIG. 3, which shows a wire with a triangular cross section and a V-shaped opening with an aperture ratio, is effective in preventing clogging.

On the upper part of the wire screen Ll), a large number of brushes (2) are arranged at appropriate intervals so as to cover the entire surface of the screen. As shown, the opposing frame plates +31, +

That is, the drive shaft (

Arch-shaped windows (8a>, (8a) are bored in 31, and are in communication with these eccentric cams +51, +51, respectively. Also, there is a window (8a) located away from the frame plate (3) on the exit side of the granules. Using the supporting part paulownia (7) provided at the position as a fulcrum, (J
A pair of horizontal rods 161, +61 are provided so as to be substantially parallel to the screen, and are in sliding contact with the upper surfaces of the 14-core cams +51, +51.

8) is provided and is formed so that it can move on the lateral il+6+ and tGl.

The center of the disc of the eccentric cam (6) and the drive shaft (4)
) when the center of the arched window hole (3a) aligns with the upper edge of the cam (51), the brush (2)
) is formed so that the lower end of the slot is approximately fused to the upper surface of the screen [+1], and the lower edge of the window hole (3a) is formed such that the lower edge of the window hole (3a) is formed so as to be substantially fused to the upper surface of the screen [+1].
4) is provided with a gap so that it can rotate without hindrance.

The drive shaft (4) that drives the brush frame is driven by a chain or belt from an electric motor (not shown) so as to rotate in a clockwise direction (in FIG. 1).

In addition, the hopper (8) into which the granules fB) should be charged is installed at the hand 1]1j of the screen f++, and is designed to feed the granules (B) a little bit from the mouth of the knife onto the screen (1). Below the screen (1) is an outlet (91 is a trench) for the separated small grains, and at the end of the screen is the exit for the remaining grains (large grains) that have been sorted out. 140 (10
) is provided.

Next, the operation of the sorting device of the present invention will be explained.

FIGS. 4 to 8 show the state in which the fixed frame of the seven-piece frame is in operation.

Figure 4 shows the state when the frame to which the 7-wheel is fixed is mounted on the bomber side. At this time, the center of the disk of the eccentric cam (5) is horizontal to the right side of the hanging center of the drive shaft (4). , the lower end of the brush of the flange (2) is in almost contact with the upper surface of the screen (1), and the right end of the Senbari (6) is affected by the eccentric force A.
The roller 18) at the upper left end of the frame plate (3) rests on the upper surface of the +51 and is on the IV+ rod (6).

Next, when the eccentric cam (5) rotates in the 900 clockwise direction as shown in FIG. The bottom edge of screen i
+) will be swept in the left direction (U1'' exit side).At this time, the eccentric cam (5) will sweep the arch) cedar 1 and hole (3a).
) can be rotated without any problem due to the relief at the bottom.

In Fig. 6, the eccentric cam (5) is further extended by 9 points than in the state shown in Fig. 5.
This shows the state in which the needle has rotated in the 0' hour setting direction, and the frame plate (3
) moves further to the left, and the lower end of the brush (2) sweeps the top surface of the screen (1) to the left in the same way as in the case of No. 5-.
The frame to which the brush is attached is the first to appear [closest to the 1 side].

Figure 7 shows that the eccentric cam (5) is further 9 than the state shown in Figure 6.
The frame body returns to the popper side by rotating in the direction of the 0° hour hand.
This shows the state in the middle of the J movement, where the upper edge of the arched window hole (3a) of the frame plate (3) is pushed up by the eccentric cam (5), and as it comes to the second part of the canyon, it moves to the right (backward movement). ] 7. Yokoma (
6) Use the leftmost support member (7) as a fulcrum and rotate it a little counterclockwise with [7]! The left end of the frame (3) is also slightly held up by the roller (8), and the lower end of the brush of the flan (2) and the screen (1
) The gap with
It gradually becomes smaller.

Next, as shown in Fig. 8, when the eccentric cam (5) rotates 90 degrees and changes from the state shown in Fig. 84 to the state of 1 rotation, the frame (ri) to which the brush (2) is fixed further moves to the right (returns). At the same time, the arched window hole (3a) of the frame board (3) is lowered and the lower end of the brush (2) is almost in contact with the screen (1), which is the original state ( Return to Figure 4).

In the above, the frame plate (3) is rotated during the first 0° rotation of the first stitch (
Figures 4 to 6) move leftward (forward) in a straight line on the screen fl+, and during the next 180° rotation, the entrance side of the frame plate has a high arc shape close to a half-moon shape, and the The exit side moves to the right (backwards) in a low arc shape.

FIG. 9 shows another embodiment of the frame, in which eccentric cams (5) are provided on the inlet and outlet sides of the frame, respectively.

(5)' is provided, and the frame plate (3) is provided with arched window holes (3a), (Ea') for opening the respective eccentric cams. The entire body can move evenly to the right (backwards).

As mentioned above, the device 1''''f of the present invention moves forward on the frame or screen (1) in a ladle line and moves back in an arcuate manner. The granules such as beads charged into the eccentric cam (5) are
It can be transported by sweeping.

Further, since the slits U of the screen are formed parallel to each other from the inlet side to the outlet side of the granules, the granules can be conveyed extremely smoothly.

In this way, since the particles (13) are conveyed by sweeping the screen with a brush, there is no possibility of clogging as in conventional sorting devices.

In this case, the brush (2) has a small brush and moves in a straight line.
Because it moves back and forth in an arc, it is said that the sorting accuracy is higher because the grain layer (bead layer) is flipped vertically compared to the case where grains such as τ beads are pushed lυ. There are advantages.

However, unlike those that vibrate the net 11, it is quiet with less noise, and in addition, since the brush gently moves particles such as beads, it prevents splashing from the phase adjustment and improves JS efficiency. can be increased.

As is clear from the above description, the sorting device of the present invention can eliminate various drawbacks of conventional sorting devices of this type12 and provide a highly efficient sorting device that is free from clogging. It goes without saying that the mechanism for causing the flange frame to reciprocate as described above is not limited to the above embodiment.
