Abstract

PURPOSE:To enable to continuously operate a furnace to burn used tire, preventing the environmental pollution caused by thermal gas generated from the furnace, by controlling the feeding of waste tire into the furnace, as well as to seal the thermal gas generated from the furnace. CONSTITUTION:A waste tire 16 is fed into a waiting chamber 3 by a conveyor, after it is weighed by a weighing machine 12. When the first tire 16 is fed, a waiting door 8, a middle door 7, and a feed door 6 are opened in turn, and the tire is fed into a furnace chamber 1 to be decomposed by heat or to be incinerated. The doors 8, 7 and 6 are closed till the effective combustion time for the waste tire 16 being fed in the furnace 14 is over. When the effective combustion time has come to an end, the waiting door 8 is opened, and the next tire 16, of which movement is prevented by the waiting door 8, is moved by the conveyor 9 to be fed into a middle chamber 5. Nearly at the same time when the waiting door 8 is closed, the middle door 7 is opened, and the waste tire 16 is moved into a feeding chamber 2. Then the middle door 7 is closed and almost at the same time the feed door 6 is opened, and the waste tire 16 falls into the furnace chamber 1, and the feed door 6 is closed.

Description

[Detailed description of the invention] The present invention relates to a tire loading device.

More specifically, the present invention relates to a tire loading device used in a waste tire pyrolysis furnace or an incinerator (hereinafter both will be collectively referred to as a waste tire furnace).

Conventionally, when operating a furnace that thermally decomposes or incinerates waste tires without crushing them, and inserting waste tires at regular intervals, the input section needs to have an input port that matches the outer diameter of the tire. Difficult to seal between furnace and input. In this Yuzu furnace, the pressure inside the furnace is usually positive during operation, so high heat and valuable furnace gas leak from the incomplete seal, deteriorating the environment and making operation difficult. Also, when putting it in, it may get caught in the middle and not fall. Furthermore, since there are differences in the size of waste tires, if they are mechanically fed into the furnace at the same time intervals, there will be an excess or deficiency of waste tires (hereinafter referred to as an excess or deficiency of the amount of heat supplied) during combustion and decomposition in the furnace. ).

This invention was made to solve the above-mentioned problems, and its purpose is to use it in a furnace that thermally decomposes or incinerates waste tires without crushing them, and seals the hot gas generated from the furnace. It is an object of the present invention to provide a tire charging device that controls the charging of waste tires so that the waste tires are reliably charged and the amount of heat supplied in the furnace is approximately constant over time.

Describing this invention with reference to figures showing embodiments of the invention, in Figures 1 and 2, a charging chamber 2 facing the furnace chamber 1, a waste tire waiting chamber 3, and a compartment 2.3 provided between the It consists of an intermediate chamber 5 having an exhaust part 4, a charging door 6 is provided between the furnace chamber 1 and the charging chamber 2, and an intermediate M7 is provided between the charging chamber 2 and the intermediate chamber 5.
This tire loading device further includes a standby door 9 between the intermediate chamber 5 and the standby chamber 3.

Hereinafter, the inventor of this invention will explain the experiments that led to the above invention.

The cross-sectional area of the inlet where waste tires are put into the furnace is Q, 44W.
? An experiment with a loading device shows that when there is a single tire charging chamber (not shown), for example, the furnace internal pressure is +200 mm.
When the input door is opened during operation at H,0, hot gas blows out violently, and even if you cover the stray gas with a hood etc. and exhaust it, it cannot be exhausted and a considerable amount leaks into the outside air. Also.

In addition, the door itself becomes distorted due to the heat, so even when the door is closed, a large amount of hot gas blows out. outside%
Although the leakage of hot gas was significantly reduced by exhausting from the side chamber, it was insufficient. Next, by dividing the tire loading chamber into three groups and partitioning each chamber with a door, and by exhausting air from the outside air side chamber and the middle chamber, leakage of hot gas into the outside air was almost eliminated. It is something. The above tire loading chamber was inclined at approximately 15 degrees with respect to the horizontal, and a moving device such as a col was provided on the bottom of the device so that it would fall under its own weight. In addition, waste tires vary in size, but in order to operate the furnace stably and continuously, the weight of the waste tire is measured, and this value is used to control the interval between feeding into the furnace and the amount of heat supplied to the furnace. It is kept almost constant. In other words, a weighing device is connected to a computing device, and the computing device is connected to a control device that controls opening and closing of the tire, and the effective combustion time in the furnace is calculated from the weight of the weighed waste tire. The charging time is automatically determined, thereby controlling the opening and closing of six doors in each chamber, and the amount of heat supplied to the furnace per unit time is kept almost constant.

The present invention will be described in detail below with reference to the drawings.

In Figure 1 and Figure 2, 14 indicates the main body of the waste tire furnace, and 1 is its furnace chamber. 15 shows a tire loading device according to the present invention. The weight of the waste tire 16 is measured by a weighing device 12, and then transported to the waiting room 3 by a transport device (not shown).

The waiting room 3, intermediate room 5, and loading chamber 2 are each divided by a waiting door 8, an intermediate door 7, and a loading door 6 as shown in the figure.
Regarding the sealing members (not shown) for the door 8, 7, and 6, since the charging chamber 2 is exposed to hot gas in the furnace chamber 1, one member is used for each known heat-resistant seal. However, since the room temperature in the intermediate chamber 5 is approximately 50° C., rubber or the like is sufficient as the material for the sealing portion. In addition, the hot gas brought from the furnace chamber 1 is passed through the exhaust duct 4.
Therefore, other combustion systems (not shown) or the furnace main body 14
sent to.

Next, if the waste tire 16 is kept in the waiting room 3, the waiting door 8 and the intermediate door 7 are used.
, the charging door 6 is sequentially opened, and the waste tires 16 are charged into the furnace chamber 1 and thermally decomposed or incinerated. Note that 17 indicates a door drive unit. During this time, each Ji8, 7, and 6 is opened, and the weight of the scrap tire 16 put into the furnace chamber 1 is stored in the computer 11, and
In this case, the amount of heat supplied per unit time to the furnace 14 is set in advance, and from this, the effective combustion time corresponding to the weight of the waste tire 16 is calculated. And waste tires 16 in the furnace 14
Each of the a.s. and 7.6 is closed until the end of the effective combustion time, and when the end of the effective combustion time is reached,
First, the standby door 8 opens, and by then the weight has been weighed, and the standby door 8
The waste tire 6, whose movement was blocked by the moving device 9, is moved by the moving device 9 and enters the intermediate chamber 5. Next, when the standby door 8 fails to close, the intermediate door 7 opens almost simultaneously, and the waste tire 16 moves into the input chamber 2. Then, the intermediate door 7 is closed, and at the same time, the input door 6 is opened and the S waste tire 16 falls into the furnace chamber 1, and the input door 6 is closed. The waiting door 8 opens,
The time until the input door 6 is closed, that is, the waste tires 16 are in the waiting room 3.
As an example, the time it takes to enter the furnace chamber 1 is approximately 10 minutes.
It takes seconds. Therefore, the computer 11 subtracts the travel time of the waste tire 16 from the effective combustion time previously calculated in 3.C to open and close the doors 8, 7, and 6.
The control device 11 is activated.

By virtue of the above-described structure, the present invention allows the waste tire furnace to be fed and the furnace to be operated continuously while preventing the environment from being degraded by hot gas from the waste tire furnace.
