Abstract

PURPOSE:To disperse the evaporated fuel and keep such a condition as facilitating a complete combustion by a method wherein a partition vane is arranged along the lower and inner circumference part of the comubstion cylinder. CONSTITUTION:When both air and fuel are fed to an evaporation cylinder 1 while the evaporation cylinder 1 is rotated, the fuel is gasified in the evaporation cylinder 1 and ignited to burn while it is injected from the injection holes 2 of the combustion plate 3 in a forward direction. At this time, even if the gasified fuel is made rich at the lower part of the combustion cylinder 4, the flame injected and forwarded to the front surface of the combustion plate 3 under the rotation of the evaporation cylinder 1 is fed in a forward direction while being circulated in an eddy flow. At this time, the outer circumferential lower part of the flame is acted upon a partition vane 5 to generate the turbulent flow and to cause the rich gasified fuel to be mixed with the upper lean gasified fuel, resulting in that the complete combustion may easily be performed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vaporizing burner, which can be used as a burner for grain driers and the like. In a vaporizing burner, a vaporizing cylinder that vaporizes fuel by rotation is rotated around a horizontal axis, and the vaporized fuel is combusted while being jetted forward from the jet hole of a combustion disk on the outer periphery of the vaporizing cylinder. Due to gravity, the vaporized fuel that is ejected from the combustion chamber becomes dense in the lower part of the combustion cylinder surrounding the front part of the combustion disk, and combustion in this lower part tends to be incomplete, often resulting in red flame.

The present invention aims to eliminate such defects, and for this purpose, the following technical measures have been taken. That is, a vaporizing cylinder (1) that vaporizes fuel by rotating in the central part.
, an ejection hole (which is located on the outer periphery of the vaporization cylinder (1) and burns the vaporized fuel from the vaporization cylinder (1) while jetting it forward);
2), a combustion tube (4) on the outer periphery of the combustion disk (3) surrounding the combustion flame, and a V 13iJ on the lower inner periphery of the combustion tube (4). The vaporizing burner has a partition blade (5) provided along the rear direction.

With this configuration, the present invention has the following technical effects. That is, while rotating the vaporizer cylinder (1),
When air and fuel are supplied to this vaporization cylinder (1), the fuel is vaporized in this vaporization cylinder (1) and is ignited and burned while being ejected forward from the nozzle (2) of the combustion plate (3). However,
At this time, even if the vaporized fuel becomes dense at the bottom of the combustion cylinder (4), the flame jetted to the front of the combustion plate (3) by the rotation of the vaporization cylinder (1) is swirled forward in a thin spiral. At this time, the lower part of the outer periphery of the flame is acted on by the lower partition blade (5), creating a turbulent flow, which works to mix the thicker vaporized fuel into the thinner vaporized fuel part at the top. It is possible to create a state in which complete combustion can easily occur.

In the drawing, (6) is a case that has a motor (7) inside, and the rear end of this case (6) is equipped with an air outlet (8) that is connected with a nozzle to blow hot air. A blower tube (9) is provided at the front end to guide and send out this air.
At the same time, a combustion tube (
4). At the front end of the shaft 00 of the motor (7) is a cup-shaped carburetor cylinder (1) with a small diameter at the front end and a large diameter at the rear end.
Attach this prison tube (1) to the blower tube (9).
1 and 2 are fitted to form vaporization passages 01) at appropriate intervals. The combustion tube (
4) An ejection chamber zero pier is provided, which is formed by the rear wall and the front combustion disk (3).

The combustion tube (4) is oriented forward with its axis 00 horizontally, and partition blades (5) in the front and rear direction are arranged on the lower inner periphery of the combustion tube (4) to form a spiral shape. The structure is such that resistance is provided from the bottom surface of the outer periphery to the flame emitted from the outside. 03
is a drain pipe, which is connected to the lower end of the combustion tube (4).

04) is a nozzle that supplies fuel to the front end of the blast tube (9). Oυ is an ignition heater, (IG is a flame sensor. Father, such a combustion cylinder (4) and a case (6)
) is provided inside the blow tube, and the air is blown with the outer periphery facing forward. 071 is a ventilation hole.

If the motor (7) is driven to rotate the carburetor tube (1), blow air to the blower tube (9), and supply combustion from the nozzle IV Q4), the fuel will flow through the vaporizer channel by the rotation of the carburetor tube (1). (11
) is vaporized while being pumped out, reaching the ejection chamber a-gong,
Here, it is ejected forward from the ejection hole (2) of the combustion disk (3), ignited by the ignition heater 00, combusted, and sent forward as a blue flame, which is carried along with the blast of air around the front outer periphery.

While the lower outer peripheral part of the flame swirls, it receives resistance from the partition blades (5) that protrude from the bottom to the top, creating a turbulent flow, which diffuses the vaporized P size in this part and causes it to flow under the influence of gravity. It mixes the highly concentrated vaporized fuel that is about to descend with the thinner upper vaporized fuel part to maintain a state where complete combustion is easy to occur.9 Therefore, in the lower part of the P-gun barrel (4), Red Fire
