DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid device for a hopper of an incinerator, and more particularly to a lid device for a hopper which communicates with a combustion chamber and has an inlet opening upward. While improving the airtightness of the mouth and lid,
The present invention relates to a lid device for improving safety.

[0002]

2. Description of the Related Art A lid device for a hopper of an incinerator, which is in direct communication with a combustion chamber, shuts off smoke and odor in the combustion chamber, so that the airtightness and the safety against an increase in the internal temperature are increased. We have devised a configuration that takes this into account.

[0003] In order to achieve the above object, a structure in which a small gap does not occur between the fitting contact surface between the input port of the hopper and the opening / closing lid is provided. The mainstream of the improvement is to form a surface, or to prevent a minute gap from occurring by interposing a soft material on the contact surface.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the conventional direction of improvement, and has the advantage of avoiding complications in construction, preventing smoke and odor with a simple construction, and improving safety against high temperatures in a combustion chamber. It is intended to provide a hopper cover device to secure the hopper.

[0005]

SUMMARY OF THE INVENTION The present invention is directed to a hopper having a combustion chamber, in which an inlet for incinerated material is opened upward, a groove is formed in an upper end surface of the inlet, and a water channel is formed. The lower slope of the skirt edge is immersed in the channel and the lid is closed, and water can flow inside and outside the channel separated by the skirt edge. It is assumed that.

According to the present invention, the input port of the hopper and the opening / closing lid for covering are engaged with a water channel formed on the upper end face of the input port via water at the lower portion of the skirt edge of the opening / closing lid. The lid is kept airtight by water, and acts to block smoke and odor from flowing outside.

Further, when the temperature of the combustion chamber becomes high, the water channel formed at the upper end face of the inlet is also heated, and the water in the water channel absorbs heat, becomes high temperature and evaporates, thereby promoting the heat radiation effect. In addition, the open / close lid rises and releases the abnormal pressure due to backfire or explosive explosives, so it acts as a safety valve.

Furthermore, in the configuration in which the inner surface of the opening / closing lid is inclined downward toward the edge of the skirt, water is vaporized from the incinerated material and evaporates. It has the effect of removing water and replenishing water to the water channel.

[0009]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of a main part of a hopper,
FIG. 2 is a plan view, in which 1 is a hopper, 2 is an opening / closing lid,
Reference numeral 3 denotes a water supply tank, and reference numeral 4 denotes an opening / closing operation rod.

A lower portion of the hopper 1 is connected to a combustion chamber (not shown). A groove 6 having a bottom is formed on an outer periphery of an end face of an inlet 5 which is opened upward. There are seven. A drain port 8 is provided in the upper portion of the outer wall of the groove 6 to control the amount of water exceeding a certain amount and to prevent overflow into the hopper 1.

On the other hand, the water supply tank 3 has a water supply port 9 having a groove 6.
The water supply port 9 is set at a low water flow position in the water channel 7 and the tank is stored in a vacuum state. Therefore, when the water supply port 9 is immersed in the water channel 7, the water remains in the tank, but when the water supply port 9 appears in the outside air, air enters the tank and the water is supplied to the water channel 7. Will be replenished.

A skirt edge 10 is provided below the main body 11 covering the input port 5 of the opening / closing lid 2, and a lower portion of the skirt edge 10 is formed at the upper end of the input port 5 when the lid is closed. It is to be immersed in and closed. The lower end of the skirt edge 10 is not in contact with the bottom surface of the groove 6, and the regulating legs 12 (provided at the four corners in the drawing) are partially extended so as to be at an intermediate position, and are stably placed on the bottom surface of the groove 6. Is what you do.

Therefore, the water inside and outside of the water channel 7 partitioned by the skirt edge 10 is free to flow water, and the inlet 5 of the hopper 1 is shut off from the outside air by the opening / closing lid 2 and the water in the water channel 7, This prevents the smoke and smell inside 1 from being released to the outside air. The positioning of the skirt edge 10 when the lid is closed can also be performed by attaching locking means such as a stopper (not shown) to the opening / closing operation rod 4.

The inner surface 13 of the main body 12 of the opening / closing lid 2 covering the input port 5 of the hopper 1 has a shape in which the central portion is higher and the lower it is inclined toward the periphery and reaches the stopper edge 10. Therefore, the water vapor generated in the hopper 1 (including the combustion chamber) hits the inner surface 13 of the opening / closing lid 2 and becomes water droplets. The water droplets flow down along the slope of the inner surface 13 and are further drained along the skirt edge to the water channel. The Rukoto.

[0015]

As described above, the present invention achieves the airtightness between the hopper and the opening / closing lid via the water channel, and can prevent the outflow of smoke and odor by water. The structure has the effect of being simplified, and also has the effect of acting as a safety valve capable of releasing backfire and explosion pressure.

The water in the channel absorbs the heat in the hopper (combustion chamber) and has an effect of preventing abnormal heating. On the other hand, the inclination of the opening / closing lid supplies the water evaporated from the incinerated material to the channel as water droplets. In addition to efficiently removing water from the hopper (combustion chamber), it has the effect of replenishing water to the water channel.
