Abstract

PURPOSE:To obtain an incinerator of lightweight and easy to be maintained, in which uniform combustion is taken place, by rotating an incinerator having a water cooling chamber which surrounds the outer periphery of a drum, as well as to provide a number of nozzles for combustion air, opening to the inside of a drum. CONSTITUTION:A plurality of pipes 2 are provided to the outer periphery of a drum 1 in the axial direction, and a number of nozzles 3 for combustion air are provided to the inside of a drum by the intermediary of pipes 2 in order to inject air. The outer sides of pipes 2 are surrounded by a water cooling chamber 4. The water gets into the chamber 4 from a pipe 6a, one of pipes 6a and 6b provided concentrically by the intermediary of a rotary joint 5, passing through the water cooling chamber 4, flowing into another pipe 6b via a pipe 4a, cooling the drum 1 all the time. With such an arrangement, an incinerator of lightweight and easy to be maintained, in which uniform combustion can be taken place by sufficiently stirring loaded combustible material, can be obtained.

Description

[Detailed description of the invention] The present invention relates to a rotating drum type incinerator.

Since conventionally used incinerators are fixed type, for example, when the incinerators are thrown in, only the surface of the wood, plastic, etc. is burned, and the inside is not burned sufficiently.Therefore, an improvement has been desired.

The present invention solves these conventional problems,
The purpose is to be lightweight and easy to maintain, and to ensure that the input materials to be burned are sufficiently stirred and incinerated uniformly.

For this purpose, the present invention provides a large number of combustion air nozzles opening into the drum, and an incinerator consisting of a water-cooled chamber surrounding the outer periphery of the drum containing these nozzles, which is arranged horizontally and rotated. Combustion air and cooling water are supplied from the outside via pipes. An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a partially longitudinal front view showing an embodiment of the rotary incinerator of the present invention, and FIG. 2 is a sectional view taken along line AA in FIG. In the figure, numeral 1 constitutes a combustion chamber with a drum that is open at one end and placed in a horizontal position, with the opening serving as an inlet for the materials to be burned.

On the other hand, a plurality of pipes 2 are provided on the outer circumference of the drum 1 in the axial direction, and a large number of combustion air nozzles 3 are provided inside the drum through the pipes 2 to inject air, etc. ing. Further, its outer periphery is surrounded by a water cooling chamber 4, and water enters the water cooling chamber 4 from a tank (not shown) by a circulation pump via a rotary joint 5 and from one of the vibros a and 5b provided concentrically. Then, it flows from the pipe 4a to the other vibro b, so that the drum 1 is constantly cooled.

Next, as shown in detail in Fig. 3, the air is connected to a pair of left and right disks 7a screwed to the outer vibro a provided concentrically, and a cylinder to which the circumferential surface of the disks is rotatably attached. 7b
From the air chamber 7 constituted by It is connected to the combustion air nozzle 3. Note that 11 is a holding shaft for fixing the pair of discs 7a;
12 indicates 01J, respectively. Reference numeral 13 denotes an annular rail fixed to the outer periphery of both sides of the water cooling chamber 40, which is placed on the row 2-14, and this roller 14 is rotated by a motor 15 via a speed reducer 16 to rotate the entire incinerator. There is. Note that there is an exhaust port 17 at the top of the entrance part of the drum 10.
is installed, and the exhaust gas is released into the atmosphere via a dust collector (not shown in the figure). Further, a pressure regulating valve 18 is attached to the outer periphery of the water cooling chamber 4 and adjusts the pressure inside the water cooling chamber. Note that although the opening of the incinerator is shown inclined upward in the figure, it may be horizontal. However, by tilting it, the material to be burned is burned inside, and there is an advantage that the input amount can be increased because it does not overflow.

In this way, the materials to be burned are sufficiently stirred by the rotation of the incinerator, resulting in uniform incineration, and the water cooling chamber on the outer periphery eliminates the need to use refractory bricks in known rotary kilns. The overall weight is reduced, problems such as maintenance of fire bricks are solved, the introduced cooling water can be reused in boilers, etc., and liquids such as waste oil can be incinerated by the air ejected from the air nozzle.

Next, as another example, if a lip 19 is provided in the axial direction on the inner periphery of the drum 1, the material to be burned will fall downward from the tip of the rib 19 by 10 rotations of the drum, thereby further increasing the stirring efficiency. , and can fulfill the role of ensuring air nozzle/1/3.

Furthermore, this rib 19 is arranged spirally around the inner circumference of the drum 1.

In the first embodiment, the combustion residue is taken out from the inlet, but as described above, the combustion residue is taken out from the inlet. The spiral shape allows for easy removal by reversing the drum.

As explained in detail above, according to the present invention, the present invention is lightweight and easy to maintain.Furthermore, the input material to be burnt is sufficiently stirred, and since the combustion air nozzle is provided, uniform incineration can be performed. There is an effect that can be achieved.
