Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a styrene foam melting and supplying device for supplying a styrene foam container into a melting furnace.

[Conventional technology]

Conventionally, a belt conveyer, a pan conveyer, etc. have been used as a melting supply device for supplying waste to a melting furnace in order to reduce the volume of waste such as containers made of expanded polystyrene containers.

However, in the conveyor as described above, since the Styrofoam container is lightweight and has a large volume, it does not move smoothly, and it is clogged at the outlet of the Styrofoam stockyard in the stockyard or causes a bridge to the melting furnace. The supply was not performed smoothly, and when clogging occurred, it was necessary for an operator to put the material into the melting furnace.

On the other hand, a Styrofoam container has a foaming ratio of about 50 times, a container thickness of about 20 mm, a small specific gravity, and is blown up by the wind, and it is extremely dangerous because it is a combustible material. There is a possibility that a worker may be exposed to hot air and exhaust gas, and there is a problem in work efficiency and safety.

[Problems to be solved by the invention]

The present invention has been made to solve the above-mentioned conventional problems, and a rotary scraper provided with a plurality of scraping blades on a flight conveyor provided in a stockyard and a rotary drum provided at an upper portion of an exit side of the flight conveyor. An object of the present invention is to provide a melting and supplying device for a Styrofoam container that can crush the Styrofoam container in the stock yard by means of a mixing drum, and cause the foam container to scatter and collide, and forcibly and smoothly supply it into the melting furnace while transporting.

[Means for solving problems]

As a means for solving the above-mentioned problems, the apparatus for melting and feeding a Styrofoam container of the present invention has a charging port on one side and a discharging port to the melting furnace on the other side for charging the Styrofoam container into the stockyard. In addition to providing a flight conveyor that moves from the bottom part under the mouth to the exit part, at the upper part on the exit part side of the flight conveyor, a rotary scraping drum provided with a plurality of scraping blades on a rotating drum is provided, and the foam supply is melted and supplied. Composed of equipment.

[Action]

The Styrofoam container put in a wide stockyard from the charging port is scraped and sent by a flight conveyor provided at the chute-like bottom, and the rotary scraping provided at the upper part on the exit side of the stockyard. It is crushed by the inclusion drum and the flight of the flight conveyor,
Scattered, collided, transported, forcedly sent to the outlet, and put into the melting furnace.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a melt supply apparatus for a styrofoam container according to the present invention will be described below with reference to the drawings. FIG. 1 is a schematic side sectional view according to the embodiment, and FIG. 2 is an A- of FIG. A
FIG.

First, this stockyard 1 is composed of a metal net or the like that has a small specific gravity and floats up by the wind, and is a combustible material that is extremely dangerous, and has a charging port 2. It has an inlet 2 on one side and a melting furnace 7 on the other side. It has an outlet 6.

Next, a flight conveyor 3 that moves from a chute-like bottom portion directly below the input port 2 in the stockyard 1 to the outlet portion 6 is provided along the slide receiving plate 4, and the flight conveyor 3 has an angle. The materials are laid sideways with a space between them, and the melting furnace 7 is connected from the bottom of the stockyard 1 directly below the inlet 2 through the case of the outlet 6 and is driven by a speed conversion motor.

As shown in FIG. 2, the roller chain 8 passes above the roller chain rail 10, and there is a gap of about 50 mm between the flight 9 of the flight conveyor 3 and the lower slide receiving plate 4. In this flight 9, waste such as Styrofoam containers can be scratched and sent.

However, even if the flight conveyor 3 is moved as it is, the styrofoam will still be in the outlet section 6 of the stockyard 1.
Stop by the side or go back.

Therefore, the rotary scraping drum 5 including a rotary drum having several scraping blades is provided on the upper portion of the flight conveyor 3 on the outlet 6 side.

The styrene foam container is crushed, scattered, and collided by the scraping drum 5 and the flight 9 of the flight conveyor 3, and is forcibly sent into the case on the outlet side 6 by the flight conveyor 3 and charged into the melting furnace 7. To be done.

With the above configuration, the styrofoam container in the portion on the outlet portion 6 side in the stockyard 1 is not clogged,
It is scraped by the rotary scraping drum 5, crushed and scattered,
After the collision, the Styrofoam container is sent to the outlet portion 6 and continuously charged into the melting furnace 7 for a long period of time, as confirmed by the experimental results using the actual machine.

[Effect of device]

The present invention, when the Styrofoam container is fed into the melting furnace and melted, if the Styrofoam container is directly put into the melting furnace, it is exposed to the hot air and exhaust gas of the melting furnace, which is dangerous and the working efficiency is poor. Before putting it into the stock yard, once put it in the stock yard, install a flight conveyor in the stock yard, and at the upper part of its exit side, install a rotary scraping drum provided with multiple scraping blades on the rotary drum. Put the Styrofoam container into
First, by crushing and crushing by the rotation of the scraping blade, the styrofoam pieces can be crushed into smaller pieces. As a result, the volume can be reduced and the transportation efficiency can be increased.

Further, unlike the forcible pressure contact by a rotating roller or the like, an appropriate pressure contact due to crushing and scattering is performed, so that a complete dumpling is not formed in the melting furnace, and an appropriate space pressure contact is obtained. Therefore, there is an effect that the melting efficiency is good at the time of melting, the melting is fast, and the combustion efficiency is large.

In other words, in the present invention, it is possible to improve the transport efficiency by appropriately pressing the styrofoam particles together, to crush by rotating the scraping blades of the rotary scraping drum, and thereby to perform crushing again due to the collision of the styrofoam particles. Moreover, since the styrofoam can be scattered and transported in the traveling direction at the same time by rotating the rotary scraping drum, it is possible to efficiently perform crushing and transportation, volume reduction and melting particularly in a styrofoam container having a large space. It has a tremendous effect. Moreover, since the Styrofoam container is easy to be crushed, and the content is almost space, it can be crushed easily by the rotary scraping drum, whereby the space can be easily destroyed and its volume can be greatly reduced. Has the effect.
