Abstract

PURPOSE:To feed chips reliably to an incinerator without causing the bridge phenomena by inclining one side wall at the screw feeder side of a storage tank with such angle as higher than the rest angle of waste tire chip while inclining the other side wall inwardly in the opposite direction. CONSTITUTION:Waste tire chips 2 thrown into a storage tank 8 by a throw-in conveyor 20 are carried in a trough 12 through ribbon screw vanes 11 and fed through a discharge port 12b at the end of the trough 12 to a scale 6. Then they are thrown through a throw-in port 4 into an incinerator 1 and burnt while at the same time heat is recovered through a heat transmission pipe 5. Here, one side wall 13 of the storage tank 8 provided along said vanes 11 is inclined with higher angle than the rest angle of chips 2. Consequently, the component of the self-weight of chips 2 functioning vertically against said side wall 13 is reduced to make said chips slippery. The other side wall 14 is inclined inwardly in the opposite direction from the side wall 13. As a result, the component of the self-weight of chips 2 will not function to prevent the bridge phenomena.

Description

[Detailed description of the invention] ``Ki-ni 1ru'' relates to a waste tire chip supply device.

Currently, bunched tires are cut into chips by a crusher and sent one by one to an incinerator via a chip feeder.
There, the waste is incinerated and heat is recovered.

By the way, the chip 4A Aha device for supplying the D6 tire chips (hereinafter simply referred to as chips) to the incinerator includes a chip storage tank and a ribbon-shaped screw J: ] 4
N ) e screw feeder. Conventionally, this chip storage tank has been shaped like a spring, and both of these tanks have been shaped like a spring. Although the I wall is vertical, the vertical pressing against the side wall when the chips are lowered causes a bridging phenomenon due to the frictional resistance caused by the force, which creates a cavity around the screw feeder and prevents the chip from being fed. The drawback was that it was impossible to do so.

Therefore, the present invention has one of the above drawbacks. An object of the present invention is to provide an extinguishable waste tire chip supply device.

That is, the present invention provides a storage tank for storing waste tire chips, and a screw feeder having a ribbon-shaped screw blade for supplying the waste tire chips in the storage tank to an incinerator.
This is a waste tire chip supply device that includes a C screw feeder along one hole jb portion of the bottom wall of the storage tank, and one side wall of the storage tank 1a on the screw feeder side. A waste tire chip characterized in that the bottom wall has a large angle of repose and is tilted at an angle of less than 90°, and the other side wall erected from the other end of the bottom wall is inclined parallel to the above-mentioned one wall. In the feeding device, with such a configuration, the screw feeder side of the storage tank is inclined at an angle larger than the angle of repose of the waste tire chips, so that the return ear tips acting perpendicularly to this side wall are self-propelled. However, since the other side wall is tilted inward in the opposite direction to the one side wall, the component force of the tire chip's own weight no longer acts on it, and therefore the bridging phenomenon as in the conventional case does not occur as a whole. Therefore, waste tire chips can be reliably supplied to the incinerator.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. (1) For example, waste tire chips (hereinafter simply referred to as chips) that are caught in a crusher and cut into chips (
An incinerator for incinerating chips (2), in the middle of its side wall (3) there is an inlet (4) with protruding teeth for inserting chips (2), and a heat recovery inlet (inside υ) is formed. Heat exchanger tube (5)
is installed. (6) is the incinerator placed on the top surface of the inlet (4). (7) is the incinerator (V in υ).
This is a chip supply device for supplying chips (2) at a fixed rate, and has a chip storage tank (hereinafter simply referred to as a ``plant'') (8).

Immediately, to one end of the bottom wall Q1 of the storage tank (7), the -UU portion of the U-shaped trough @ in which the ribbon-shaped screw blade (B) is arranged at the rotation point is connected, The other side of this trough (6) has an angle (θ

Furthermore, the bottom wall θQ is set such that the chips (2) in the storage tank (8) are easily expelled into the trough.
The other end is slightly inclined so that one end is higher than the other end. The ribbon-shaped screw blade (b) is provided to protrude from the front wall QrJ of the storage tank (8), and its front end extends to a position above the meter ffl device (6), so that the trough ( The protruding part (12a) of 6) has a cylindrical shape with a memorized upper half, and a discharge port (12a) at the tip.
