Description

  The present invention relates to a rotary incinerator that incinerates waste while rotating a drum serving as a combustion chamber, and particularly relates to a rotary incinerator suitable for incineration of dead chickens having a high water content.

  2. Description of the Related Art Conventionally, a rotary incinerator has been proposed in which an incinerated material in a combustion chamber is incinerated while being stirred by rotating a drum-type combustion chamber. This type of conventional rotary incinerator is a single-cylinder cylinder with various devices to improve the combustion effect by adjusting the diffusion and movement of the waste introduced by installing stirring blades and auxiliary plates inside. It has been subjected.

  For example, in a rotary incinerator that can incinerate incinerators in a combustion chamber while rotating a drum in a horizontal position with a rotary drive device, the inner surface of the combustion chamber is formed with a fire wall, and the inner surface of the combustion chamber The cross section in the circumferential direction is formed to be a polygon that is equal to or greater than a quadrangle, and when the incinerated object is lifted upward as the drum rotates, the combusted object does not slide down the combustion chamber surface as it is. There has been proposed a rotary incinerator that improves the stirring action of the combusted material so that the entire combusted material is combusted uniformly.

Japanese Patent Laid-Open No. 08-312932

  However, waste and raw garbage with high moisture content, such as dead chicken, will not burn after the surface layer has been incinerated in order to burn all the waste put into the furnace. There was a problem that it took a long time to completely incinerate the entire incinerated product and the thermal efficiency was lowered. In view of the problems of the prior art, the present invention provides a rotary incinerator capable of efficiently combusting waste with high water content such as dead chicken efficiently by reversing the combustibles in the drum well and repeatedly heating them. The purpose is to provide.

  As a means for solving the above-mentioned problems, the present invention provides a combustion in a rotary incinerator that can incinerate an incinerator in a combustion chamber while rotating a cylindrical drum having a combustion chamber in the circumferential direction. A first feature is that a rooster (grate) that can be rotated forward and backward along the inner periphery is provided in the room. A second feature is that a lid for closing the drum is provided, and a fitting recess capable of horizontally fixing the rooster is provided on the side of the lid. Further, a third feature is that a slope that decreases toward the discharge port side of the incineration ash is provided. Furthermore, the fourth feature is that the rooster is formed in a polygonal column shape.

The present invention has the following excellent effects.
(1) The incinerated material in the combustion chamber is finely crushed and stirred by the rooster, the mixing of air is promoted, the combustion efficiency is improved, and the burner operation time is short.
(2) Since the rooster is provided so as to be able to rotate forward and backward, the incineration ash can be equally distributed in the ash receiving tank and can be accommodated uniformly, and labor for discarding the incineration ash can be saved.
(3) Since the gradient which becomes low toward the discharge port side of the incineration ash is provided, the incineration ash can be automatically discharged by the rotation of the drum.

It is a partial cross section side view of the rotary incinerator concerning the present invention. 1 is a front view of a rotary incinerator according to the present invention. It is a perspective view which shows an example of a rooster.

  An embodiment of the rotary combustion furnace of the present invention will be described below with reference to the drawings.

  Hereinafter, as shown in FIGS. 1 to 3, the rotary incinerator according to the present invention includes a cylindrical drum 2 having a combustion chamber therein and a pair of driving rollers 8 rotating in the circumferential direction while being covered in the combustion chamber. This is a rotary incinerator that can incinerate incineration.

  The cylindrical drum 2 is provided with a fire wall having a predetermined thickness using fire resistant cement in a steel plate cylinder, and the inside of the fire wall becomes a combustion chamber. In the combustion chamber of the cylindrical drum 2, a rooster (grate) 3 is provided that can rotate forward and backward along its inner periphery.

  The rooster 3 is formed in a polygonal column shape, in this embodiment a hexagonal column shape, and the incinerated material in the combustion chamber is finely crushed and agitated by the rooster 3 to promote air mixing.

  A lid body 1 for closing the drum 2 is provided on the front side of the cylindrical drum 2, and a waste inlet 9 and a burner 4 that are incinerated materials are attached to the lid body 1. In the state where 1 is closed, the rooster 3 is burned in a state where it is sequentially fixed while rotating manually by 120 degrees.

  The inner surface of the lid body 1 is provided with a fitting recess 1a capable of fixing the rooster 3 horizontally, and the roaster 3 is manually rotated, fixed at a desired position and burned, so that the entire incinerated object It can be burned evenly.

  The entire rotary incinerator is provided with a gradient that is inclined downward by about 2 to 3 degrees toward the discharge port side of the incineration ash 12. Thereby, the incinerated ash 12 can be automatically discharged by the rotation of the cylindrical drum 2.

  That is, a waste inlet 9 is formed at the inlet of the cylindrical drum 2, and this inlet 9 is closed by a door. In addition, fireproof cement is placed on the inner surface side of each of the lid 1 and the insertion port 9. The burner 4 discharges fuel from a nozzle projected from the inner surface of the cylindrical drum 2 to emit a flame.

  An exhaust cyclone 5 is installed on the outlet side of the cylindrical drum 2 and is connected via the communication path 2a. Further, a chimney 6 is attached to the upper part of the cyclone 5. Note that fireproof cement is placed on the inner surfaces of the communication passage 2a and the cyclone 5, respectively.

  In the rotary incinerator of the present embodiment, the combustion ignited by the burner continues to burn with its own combustion heat in the rotating drum. That is, the combustible is completely burned while self-combusting, and the ash 12 is dropped from the rooster 3 and discharged.
