Description

[Detailed Description of the Invention] The present invention is used in grain driers, greenhouses, etc., and particularly relates to an agricultural oil burner equipped with a combustion tray that gasifies and burns oil supplied from a fuel supply path.

Conventionally, in this type of oil burner, a preheating plate is provided separately from the combustion plate, and an ignition member attached to the preheating plate is ignited to burn the oil in the preheating plate, and the combustion flame burns the oil in the combustion plate. It is configured to preheat and ignite to bring the entire combustion tray to a desired combustion state, but has the disadvantage that the structure is complicated and expensive due to the preheating tray and its oil supply structure.

The purpose of the present invention is to modify the device so that it does not require a preheating pan and can be manufactured easily and inexpensively.

Next, embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 1 and 2, a grain storage chamber 1 is provided in the upper part of the body, and two drying passages 2, 2, which allow the grains filled in this storage chamber 1 to flow down under their own weight are provided.
A hot air cylinder 4, an oil burner 5, which introduces hot air to be supplied through ventilation holes 3 of a plate forming each of these drying passages 2, 2, and a hot air cylinder 4 heated by the burner 5, A drying section 7 having rotating fans 6 for sucking and introducing the fluid is provided below the storage chamber 1. A rotary valve 8 takes out a set amount of grains from each of the drying passages 2 at set times, a screw conveyor 9 that transports the grains from these rotary valves 8, 8 laterally and collects them in the center of the machine. conveyor 9
The structure is such that the grains from the drying section 7 are returned to the storage chamber 1 by the cooperation of the vertical screw conveyors 10, which lift and supply the grains from the drying section 7 to the storage chamber 1. Then, grains of rice, wheat, etc. are supplied from the hopper 11 and filled into the storage chamber 1 by the screw conveyors 9 and 10, and the filled grains are circulated between the drying section 7 and the storage chamber 1. A tensile type grain dryer is configured for drying and taking out dried grains from a cylindrical body 13 by swinging open a lid 12 for an outlet of a vertical screw conveyor 10.

To construct the oil burner 5, as shown in FIG.
, the first secondary combustion tube 17 and the second secondary combustion tube 18
are connected in sequence.

Then, a cylindrical body 21 that forms a flow path 20 for supplying oil from the oil supply pipe 19 from the back side to the top side of the combustion plate 14 is screwed onto the boss portion 14a provided in the center of the combustion plate 14. At the same time, a sheet metal cap 22 externally fitted onto the boss portion 14a
4 is press-formed on the inner surface as shown in Figure 5.
The recessed grooves 23 form a flow path that distributes and supplies oil from the flow path 20 into the combustion dish 14 in its circumferential direction, and as shown in FIGS. 3 and 4, An annular ceramic sheet 24 as a porous ignition member impregnated with petroleum supplied thereto is installed in the combustion dish 14, and the ceramic sheet 24 is heated to actively vaporize the petroleum impregnated therein. Then, a ceramic electric heater 25 for ignition is inserted, and the ceramic sheet 24 is ignited. Then, the combustion body 15 is placed at a position where it is heated by the combustion flame in the ignited ceramic sheet 24,
The oil in the combustion tray 14 is preheated by receiving radiant heat from the heated combustion body 15 from above, and as the preheating progresses, the oil vaporizes throughout the interior of the combustion tray, and is ignited by the combustion flame and combusts. It is configured.

In the combustion body 15, as shown in FIG. 3, stoppers 15a for preventing the ceramic sheet 24 from floating up from the combustion dish 14 are protruded from three locations on the bottom surface side, and the combustion body 15 is prevented from floating up from the ceramic sheet 14. It is configured to double as a blocking device.

Incidentally, the receiving tray 26 shown in FIG. 3 is used to recover oil that is excessively supplied to the combustion tray 14 and overflows from the vent hole 27 thereof. Alternatively, the bracket 28 shown in the figure is for attaching the burner 5 to the body.

The ceramic sheet 24 can be changed to one made of asbestos, glass fiber, etc., and these are collectively referred to as the porous ignition member 24.

In summary, in the above-mentioned agricultural oil burner according to the present invention, the fuel supply path 20 is provided to the combustion tray 14, and a porous ignition member 24 impregnated with the oil supplied to the combustion tray 14 is provided. A heater 25 is installed on the bottom surface of the combustion pan 14 and ignites the oil impregnated in the porous ignition member 24.
The combustion chamber 15 is attached to the porous ignition member 24 and is heated by the oil flame combusted by the porous ignition member 24. The combustion body 15 is disposed above the combustion pan 14.

That is, the porous ignition member 24 impregnated with petroleum supplied from the fuel supply path 20 to the dish portion of the combustion dish 14 is ignited by the heater 25, and the combustion body 15 is heated by the combustion flame generated by this ignition. The oil in the combustion pan is gasified by receiving the heat from the heated combustion body 15 from above, and the gasified oil is ignited by the combustion flame of the porous ignition member 24 to spread the desired amount over the entire combustion pan 14. Since it is configured to lead to a combustion state, it is possible to eliminate the need for a conventionally provided preheating pan and a structure for supplying oil thereto. It has become possible to obtain a desired combustion state over the entire combustion dish 14 with a simpler and cheaper structure than the conventional one.
