Description

[Detailed explanation of the invention] (a) Industrial application field This invention is a system in which several sorting disks each having a number of potholes formed on the side are rotatably mounted on a horizontal axis at intervals. This invention relates to a sorting disk in a disk-type particle size sorter, which is constructed by stacking the sorting disks and diagonally disposing a receiving gutter between the sorting disks to take out the particles scooped up by a pot hole.

(B) Prior art As mentioned above, conventional disk-type particle size sorters in which sorting disks are mounted on a horizontal axis at intervals and a receiving gutter is provided diagonally between the sorting disks are known, for example. This is known as disclosed in Japanese Patent Application Laid-open No. 136688/1983.

However, since the sorting disk shown in this publication is formed into a flat plate with a pot hole formed on its side, the scooping action of the pot hole is insufficient and its function is not fulfilled, resulting in poor sorting performance. There are still problems on the surface.

(c) Problems to be solved by the invention The present invention is based on the fact that the scooping action of the conventional sorting disk through the pot holes is insufficient and its function is not fulfilled, leaving problems in terms of sorting performance. It was devised for the purpose of making the scooping action by the pot hole more effective so that it can fully fulfill its function and improve the sorting efficiency.

(d) Means for solving the problem Therefore, in the present invention, several sorting disks each having a number of pot holes formed on the side surface are rotatably mounted on a horizontal axis at intervals. In a disc-type grain size sorter constructed by diagonally installing a receiving gutter between the sorting disks, the purpose is achieved by forming the sorting disks as follows.

That is, the sorting disk is formed in the shape of a bowl, with the edge in which the pot hole is formed being concave.

(E) Effect According to this configuration, the short particles that have accumulated in the pot hole are scooped up by the rotation of the sorting disk and fall upward, and these falling particles are caught by the receiving gutter and flow down. The short particles are taken out and sorted into large and small grains. At this time, the pot hole is formed along the concave side of the bowl-shaped hole, so that the particles that have accumulated in the pot hole are As a result, particles do not come off from the pot hole during scooping, but are scooped up to the top, where they are detached and fall into the receiving gutter, ensuring a reliable scooping action. It is carried out in

(f) Examples The present invention will be specifically explained below using example figures.

An input port 2 for materials to be sorted is provided on the right side of the machine body 1, and a large particle discharge port 3 is provided on the left side.
A horizontal shaft 4 is rotatably suspended horizontally within this machine body 1, and hollow ring rings 5... are respectively attached to the horizontal shaft 4 at appropriate intervals, and a sorting disk is attached to each hollow ring ring 5... 6
...Fit and fix.

This sorting disk 6... is made by pressing a single plate, forming a large number of pot holes 7 on one side of the plate into which short particles can fit, and forming a convex portion on the back surface by forming the pot holes 7. 8 is formed. This sorting disk 6... is formed into a bowl shape with one side in which the pot hole 7 is formed concave, and this concave side faces the right side of the machine body 1, that is, the input port 2 side. There is.

Further, between the sorting disks 6, there is provided a receiving gutter 9, which is obliquely provided with its upper end located near the upper circumferential portion of the hollow ring 5 and its lower end at the lower side.

Reference numeral 10 denotes a support rod provided at the opening 11 in the hollow ring 5, and a jump piece 12 for transportation is attached to the support rod 10. Reference numeral 13 communicates with the lower end of the receiving gutter 9... This is a gutter for collecting small particles.

In the figure, 14... are the supporting legs of the fuselage 1.

Therefore, when the sorting disk 6... is rotated in the direction of arrow A and a mixture of long and short grains is fed into the machine body 1 from the inlet 2, it will be deposited at the bottom of the machine body 1 as shown by the imaginary line in Figure 2. The particles fit into the pot hole 7 of the rotating sorting disk 6 while forming an inclined mixed particle layer a, and are about to be scooped upward. At this time, long grains among the stuck particles fall off from the pot hole 7 at the initial stage of scooping up, fall onto the upper surface of the mixed grain layer a, and land on the jumping piece 12 attached to the support rod 10 of the hollow ring 5. While being stirred, the
1 and flows to the left. In this way, the long particles pass one after another through the port 11 and are finally taken out from the large particle discharge port 3.

In addition, the short particles are stuck in the pot hole 7 and are received by the pot hole 7 from below, and are scooped up upwards without detaching. It falls on 9... Short particles that do not fit into the pot hole 7 float to the upper surface of the mixed particle layer a by the rotation of the sorting disk 6, and pass through the port 11 together with the long particles to the left. , and here again, as described above, the pot hole 7
Under the scooping action of removed.

Further, the convex portion 8 formed on the back surface of the pot hole 7 acts as a convex surface to agitate the mixed particle layer. In this case, the convex portion 8 is formed along the convex surface, so that the mixed grains can see the right side and have less resistance to flow to the left side, and the mixed grain layer is not unnecessarily agitated too much.

(g) Effects of the invention As explained above, the present invention consists of several sorting disks each having a number of pot holes formed on their sides, rotatably mounted on a horizontal axis at intervals. In a disc-type large-grain sorter constructed by diagonally installing a receiving gutter between sorting disks, the sorting disk is formed into a bowl shape with the side for forming the pot hole concave. This pothole has a large effect on the particles from below, and the particles do not come off from the pothole during scooping, and are reliably scooped upwards. By making the action more effective, the function can be fully demonstrated, and the sorting performance can be improved.

In addition, as in the example, the convex part formed on the back side of the pot hole is formed on the convex side to stir the mixed grain layer, so that the mixed grains flow from the right side to the left side. Since the resistance is small, there is no need to stir too much.
