JPS607177B2 - Burner in grain dryer - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION Unless the flames generated from the burner tray of the burner, which is the heat source of the hot air blown into the grain dryer, rise evenly, hot air of uniform temperature cannot be obtained and the grains cannot be dried uniformly.

The hot air in the part where the flame rises strongly has a higher temperature than the hot air in the part where it rises weakly, so when this is blown into the drying room, the grains that come into contact with the hot air at a higher temperature become overdried, and the grains that come into contact with the hot air at a lower temperature become dry. The grains will be insufficiently dried.

However, the flame generated from the burner's combustion plate is uneven because the combustion plate is tilted, and fuel oil that accumulates in a lower place generates more intense flame heat than that in a higher place.

It was also found that this phenomenon occurs because the grain dryer body to which the burner is attached is installed at an angle, even if the burner itself is horizontal. The present invention is based on this knowledge and is an invention of a burner whose purpose is to obtain an average flame even if the dryer itself is tilted.

To explain the embodiment shown in the drawings, 1 is a combustion dish;
It is glued into a saucer 3 in which mounting pieces 2 are bored at equal intervals around the periphery.

In the illustrated embodiment, there are three mounting pieces 2. Reference numeral 4 denotes a burner outer cylinder in which a trumpet-shaped heat dissipation cylinder 5 is mounted horizontally.An adjustment screw is inserted from the bottom of the mounting piece 2 into a screw hole 6 bored in the hem of the outer cylinder 4 which is attached to the body A of the grain dryer. The adjusting thread 7 between the mounting piece 2 and the outer cylinder 4 is fitted with an extension spring S.
Wrap around.

Reference numeral 8 denotes a stopper which is fixed to the adjusting screw 7 and comes into contact with the lower surface of the mounting piece 2 to prevent the screw 7 from being pushed by the spring S and coming off.

Reference numeral 9 denotes an oil supply pipe that extends vertically through the center of the receiving tray 3 and the combustion tray 1, and allows fuel oil to flow down onto the combustion tray 1 from the spout at the upper end.

10 is a secondary combustion plate superposed on the combustion plate 1, 11 is a receiving plate 3
Asbestos for ignition is placed on the bottom of the fuel tank, and the fuel oil that has soaked into the asbestos is ignited.

Reference numeral 12 denotes an outside air inlet that is connected to the side surface of the saucer, and 13 represents an air intake plate that is attached to the outer cylinder 4 opposite to the heat radiation cylinder 5, and has a large number of outside air intake holes.

To use the present invention, first, fuel oil is supplied onto the combustion pan 1 through the oil supply pipe 9, and the asbestos 11 of the saucer 3 is ignited after the oil has soaked into the asbestos 11 of the saucer 3 through the through hole in the combustion pan 1. While observing the flames rising above the combustion plate 1, the adjustment screws 7, which can be inserted into the mounting pieces 2 protruding at equal intervals, are rotated against the extension spring S and attached to the fuselage A. outer cylinder 4 and mounting piece 2
Finely adjust the distance between the two and make the flames rise evenly.

The position of the combustion plate 1 when the flame rises evenly in this way is the horizontal position. In short, according to the present invention, even if the dryer body A is bent, it can be calibrated to the horizontal position by rotating each adjusting screw 7 and finely adjusting the inclination of the combustion plate 1. Not only is this possible, but the fuel oil is evenly spread over the combustion plate, preventing uneven combustion and increasing combustion efficiency.
