Abstract

PROBLEM TO BE SOLVED: To solve problems, for example, that when waste plastic is subjected to thermal decomposition treatment as a raw material, since pieces of the waste plastic have no shape, pieces of the waste plastic cling each other so that bridging is generated in a hopper, and in addition, the waste plastic is lightweight so that its flowability is not good, pieces of the waste plastic cling each other or static electric charge is generated, difficulty of transit for transportation and discharge in respective devices results.SOLUTION: A rake hopper discharge side plate is inclined at a flight scraper of a chain conveyor which moves on a hopper bottom plate of a storage or relay hopper, and along it, the waste plastic is raked and taken down by the chain conveyor from an upper part to a lower part for transporting the waste plastic to a discharge port.

Description

The present invention relates to transfer and transfer of non-molded aggregates such as waste plastic and bark, and other substances having a high viscosity or moisture adhering or moisture content through a storage tank. .

In the process of producing renewable energy from collected plastic (hereinafter referred to as waste plastic), in the process of producing oil, pulverized coal and hydrochloric acid by pyrolysis, the waste plastic is put into the raw material tank and the following equipment is installed from the raw material tank. When feeding or transferring to the tank, the unloading processed material and a large amount of moisture adhering to the tank when transferred from the tank may cause unstable cutting due to static electricity generated due to the movement of the waste plastic. It was difficult.

The biggest cause of difficulty in quantitative cut-out is due to the fact that the moisture content shown above and the specific gravity of the waste plastic of the raw material are 0.3 and the apparent specific gravity of the aggregate is very light, 0.2. . They are intertwined and mixed with static electricity. These waste plastics were trash that was disposable in human society and could not be reused.

In the process of supplying the garbage to the pyrolysis tank, at least the ground hopper is supplied with a forklift etc., and when stocking for several hours, the larger the hopper opening receiving area, the better the workability, Since the payout area remains large and is not cut out, the lower payout port is narrowed.

It becomes convenient to install a conveyor or the like in the squeezed mouth by reducing the hopper side wall surface downward. Since the specific gravity is heavy and not granular or uniform, the raw material is clogged here, causing a problem. The problem is that the resistance of the hopper wall is reduced by narrowing the bottom of the hopper wall into a pyramid shape, and the processed material is light, and the weight does not fall down due to its own weight.

If it does not slide down, as a method of mechanically applying force to waste plastic or high moisture content bark, etc., stir the blades on the vertical shaft in the hopper to break the balance of the contents, or put the screws upright. Flow energy is given by rotating, etc., and a cavity is formed to the point where force is exerted, but the whole has a low specific gravity, so it does not sink and a bridge shape occurs between the wall surfaces. Also, as a drawback, it was impossible to draw out quantitatively.

If waste plastics are stacked for more than 2 rice, there is a risk of spontaneous ignition, and it is impossible to accumulate a large amount and add self-weight. As an improvement measure, there are a method of arranging several paddle screws in the middle of the hopper and rotating them to eliminate the bridge, and a method of measuring the solution by installing the same paddle screw at the bottom of the hopper. There was a problem that the adhesion grew and the paddles were blocked.

Problems to be solved by the invention

The problem to be solved is to move and cut out an appropriate amount through the receiving hopper regardless of the size of the foreign matter or the light weight of the specific gravity even if the amount of other foreign matters is mixed or the water content is large.
If a drive unit or device is provided on the hopper upper receiving side, there is a problem that the receiving side is blocked, and there is a difficulty in installing facilities that obstruct the receiving side.

Using the hopper bottom plate, the chain conveyor mounted on the bottom plate is run in the unloading direction. The hopper side plate surrounds three directions, and there is no other one side plate side. Install the scraper plate on the chain conveyor that stands on the side plate position that should be used as the discharge port for the processed material, and tilt the upper part to the hopper side. The partition plate is placed between the outer and inner swivel chains. Insert.

The moving direction of the standing chain conveyor is moved downward, and the lower end of the lowering is sent out to the oblique upper part of the discharge outlet running on the hopper bottom plate. The chain rotates while maintaining a gap, and the chain turns outward from the partition plate and advances.

The two chain conveyors for horizontal running and oblique running are connected endlessly by a scraping plate. While moving the processed material on the hopper floor toward the outlet outlet, the standing chain conveyor is also moved downward. Although the waste plastic tries to float up, it moves with an inclination so that the upper part of the standing chain conveyor falls into the inner surface of the hopper.

The horizontal chain conveyor scrapes the bottom plate and turns the chain down at the turnover position on the discharge port, reverses the reverse side of the bottom plate, reverses at the rear end of the bottom plate, and the rear side wall plate on the bottom plate and the bottom plate. Go through the space and return to the bottom plate.

In the hopper, the upper part is tilted, and the lower part of the horizontal chain conveyor outlet is located outside the turning position, and both turning parts are displaced. It is placed outside the turning position of the vertical feed wheel, and both turning parts are deviated. The turning position of the vertical feed vehicle is placed diagonally above the horizontal vehicle, and the width of the gap of this distance can be adjusted to the foreign matter mixed with the processed material, and the limit of the conveyance amount of the conveyed product is In addition, it is possible to vary the transport amount by controlling the transport speed of both chain conveyors, which makes it possible to adjust this gap.

Originally, scraping with a chain conveyor will cause spillage at the top and bottom of the structure, but there will be no spillage of the conveyed product due to the advantage that the chain scraper sends it while scratching the plate. Even if the entrance of the horizontal conveyor requires an opening larger than the height of the scraper, the chain conveyor does not spill due to the movement toward the discharge port even if the waste plastic or the like descends from the upper part of the hopper.

In order to prevent waste plastic from being spilled out at the connecting portion, the discharge port is long and wide, so it is desirable that the conveyor and the receiving hopper port of the next machine be installed at right angles to the chain conveyor.
For example, when transferring to a belt conveyor, the transfer object can be loaded in a long state on the belt and placed in the chain conveyor and cross storage, and the transfer portion is prevented from being spilled.

Effect of the invention

Conventionally, it has been necessary to widen the upper opening area of a hopper that supplies waste plastic to the hopper with a bucket of a tire shovel.
In order to prevent spillage because the width of the machine receiving port of the next process or the conveyor is narrower than this hopper, the waste plastic is usually clogged in the hopper to prevent the spillage.

Even in a hopper applied to a transfer machine, it is possible to prevent clogging by the bottom of the hopper and feed, and feed it in a fixed amount.
It is difficult to use a hopper having a flow angle such that light waste plastic flows under its own weight in a small hopper or a short hopper. Clogging was eliminated by forcibly moving the vertical and horizontal directions.

The waste plastic that is pushed out by the horizontal chain conveyor is also moved downward while holding the lift of the waste plastic to the downward outlet by providing a tilt in the hopper with the movement to float by the resistance of the outlet. Conveyance is possible without clogging by horizontal movement and downward movement.

FIG. 1 shows an embodiment of the present apparatus. It is a receiving hopper (grand hopper), and scrapes waste plastic with a bucket such as a tire excavator. If it is limited to the bucket width and is too small, spillage occurs during supply.
The supply amount is arbitrary and is not limited. Also, the hopper bottom plate scrapes the bottom plate with a scraping plate and moves to the discharge port.

4). Is the head part of the horizontal scraping chain conveyor. Move on the joint hopper bottom plate with horizontal chain conveyor rake. At the head part, the chain conveyor is turned over, reversely runs on the bottom plate, and is turned over again with the tail of the chain conveyor, and reaches the bottom plate in the hopper through the gap under the hopper.
The chain conveyor requires a gap where the scraper does not interfere with the hopper gap, but the plastic moves forward in the hopper so that the waste plastic does not overflow from the gap.

Along with the horizontal movement, the timetable moves down and the chain conveyor moves downward. 6). 6. Vertical scraping chain conveyor head, As shown in FIG. 1, the horizontal chain head and the vertical chain head are separated from each other so that a gap is formed between them.

The carry-out cut-out amount changes depending on how the gap between the head and the head is shifted. Therefore, the standing chain conveyor enables sliding, and waste plastic in the hopper is scattered outside. Prevent with a hopper inclined plate. With this inclined plate and scraper, the waste plastic can be fed downward without escaping.

FIG. 2 is an explanatory diagram of the second embodiment. Unlike the ground hopper, FIG. 2 is different from the ground hopper in order to change the direction to the right or left by a relay hopper such as connecting or branching in the middle of the transport facility. Feeding conveyor, 14. Is for a drawer conveyor or transit under the hopper.

1. 3. Place the hopper (for cushion) frame on the bottom plate. 6. equipped with horizontal scraping chain hopper, Hold a vertical scraper. 6). The vertical scraper chain conveyor tilts the upper supply side and discharges it 8. Waste plastic supplied more is scraped.

This supply port may be a supply port of a final processing facility, or may be a receiving hopper, and it is possible to reliably discharge a processed material in a fixed amount.

FIG. The hopper shown in Fig. 2 shows that the transported waste plastic is supplied with BC, and the discharge outlets are on the left and right of the lower part. It is possible to pay out instead of the damper on the left or right

When reusing waste plastic irregularities, it is possible to move, store, and dispense in the necessary direction of the plant, and transport it without clogging it so that it can be supplied to the next equipment.
