Description

[Detailed Description of the Invention] This invention relates to a separation chute structure for separating metals with high purity.

Generally, in bulky waste processing facilities, metals collected using magnetic separators, etc., contain a considerable amount of rubble and combustible materials (rags, paper, vinyl, etc.), which may affect the purity of the metals. It was causing a decline in

This invention was made to solve the above-mentioned conventional problems, and the separation chute is composed of acceleration, jump, and landing chute to separate cullet and combustibles from metals with high efficiency. It was devised to improve the purity of metals.

Hereinafter, embodiments of this invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1, 2, and 3, the metal objects 1 are accelerated for a length of about 1 m at an inclination angle of about 45 to 50 degrees, facing the lower part of the discharge side of the carrying-in conveyor 2. A chute 3 is arranged, and metals 1, etc. are accelerated and flowed down by the accelerating chute 3.

A jump chute 5 having a length of approximately 500 to 600 mm is connected to the lower end of the acceleration chute 3 at an elevation angle (jump angle) of approximately 10 to 15 degrees. ,...,6 in the width direction
They are arranged in a lattice shape with a pitch of 40 to 50 mm, and the jump shoots 5 cause the cullets 7 in the metals 1 to fall downward through the meshes of the lattice, causing the metals 1 and the combustibles 8 to jump.

A landing chute 9 is arranged to be separated from the jump chute 5 by a gap G of about 200 to 300 mm and a step T of about 0 to 100 mm, and the metal object 1 accelerated and jumped by the gap G of the landing chute 9 is made to jump over it. While landing on the landing chute 9, the combustible material 8, which is relatively difficult to accelerate, is caused to fall downward from the gap G without being able to jump over it due to air resistance during the jump.

A hopper 10 is provided below the gap G,
Collect the fallen cullets 7 and flammable materials 8.

If the elevation angles of the round bars 6, .

Alternatively, the round bars 6, . . . , 6 may be formed of flat plates 6', . . . , 6' as shown in FIG. In this case, a tapered shape will similarly reduce clogging.

On the other hand, regarding the structure of the jump chute 5, as shown in FIG. 6, FIG. 7, and FIG. In addition to supporting the shoot substrates 12, 12
The holes 13, 13 on the lower end side and the both side substrates 11, 1
Lock pin 1 inserted through long holes 14, 14 of 1
5, 15 are provided, and the jump chute 5 is fixed to the substrates 11, 11 on both sides by the lock pins 15, 15, the elevation angle of the jump chute 5 can be adjusted.

Next, regarding the structure of the landing chute 9,
As shown in the figure and FIG.
If the support plate 21 with the pipe 20 fixed to the upper end is fixed to the vertical long holes 26, 26 of the angle 18 with the bolts and nuts 22, the gap G of the landing chute 9 can be fixed with the nut 19.
and the step T can be adjusted.

If the upper end of the landing chute 9 is made into a curved surface with a pipe 20, the combustible material 8 that has been caught will slide and easily fall into the hopper 10.

In addition, as shown in FIG. 11, the pipe 20
If the rotating roller 23 is used instead, the combustible material 8 will slide down more easily.

With the chute structure as described above, the metals 1, etc. discharged from the carry-in conveyor 2 onto the accelerating chute 3 flow down while being accelerated by the accelerating chute 3, and the cullet 7 flows through the grid of the jump chute 5. On the other hand, the combustible material 8 that jumped from the jump chute 5 falls from the gap G due to air resistance and is separated, and only the metal 1 lands on the landing chute 9.
It is then transported to the next process.

In place of the landing chute 9 of the above embodiment, the 12th
As shown in the figure, if the conveyor 24 is arranged to separate the jump chute 5 and the gap G, the cullet 7 and the combustible material 8 will fall into the hopper 25, and
The metal 1 lands on the conveyor 24 and is carried out to the next process.

Further, as shown in FIG. 13, if a hopper 25 is arranged to separate the jump chute 5 and the gap G, the cullet 7 and the combustible material 8 will fall onto the conveyor 24 and be carried out, and the metals 1 will be transported to the hopper 25.
They will now fall inside and be collected.

As is clear from the above explanation, this idea involves making metals, etc. flow down an accelerating chute, separating the cullet with a jump chute grid, then separating combustible materials with a gap, and sending only the metals into the landing chute. Because it was designed to make it land,
It becomes possible to separate high-purity metals.

In addition, since it is a chute system, separation work can be performed continuously, improving work efficiency.

Furthermore, basically, it is sufficient to provide an acceleration chute, a jump chute, and a landing chute.
The structure is extremely simple, there are few failures, and it can be manufactured at low cost.
