Abstract

PURPOSE:To prevent a flame from dying out when the size thereof is reduced by a strong air flow by burning a vaporizing burner in the air outside a ventilator. CONSTITUTION:The air supplied from a blower 29 is blasted at the quantity equivalent to that of the supplied kerosene through blast cylinder 27 blow cylinder 12 through hole space 21. Therefore, atomized kerosene is gasified and changed into complete mixed gas and injected into a combustion chamber 33 outside a combustion plate 30 and burnt. The hot air produced by the burning flame is supplied from a hot air supplying chamber 4 to a flow-down type drying chamber 3 to dry the grain. At this time, the air to the blower 29 is taken in from the outside of the ventilator 9. In this way, necessary air equivalent to the amount of fed kerosene can be supplied. Accordingly, it is possible to form hot air by blue flame, not only to obtain dry grain of good quality, but also prevention of flame-extinguishing even if the size thereof is reduced.

Description

[Detailed description of the invention] The present invention relates to an evaporative burner.

A conventionally known drying device is, for example, disclosed in Japanese Utility Model Publication No. 55-64622.
As stated in the publication, kerosene is supplied from a kerosene supply device and is rotated and stirred in a rotating heating bowl, but the combustion air is supplied using part of the air flowing inside the ventilation tube. Ta.

This configuration causes the following defects.

In other words, at least a strong wind of 1 to 2 m/sec per ton of unhulled rice flows through the ventilation tube of a circulation-type humidity-controlled grain drying device. However, with the above configuration, when the amount of oil is reduced and the flame is made smaller, a part of the flame may be too strong and cause a misfire.

The present invention solves this problem, and in a case where a heating bowl for rotating and stirring kerosene is installed in a ventilation tube, a blower for supplying combustion air to the heating bowl is installed outside the ventilation tube. Alternatively, it is a vaporizing burner that is installed inside the ventilation tube and opens outside the ventilation tube, which is the suction tube, so that combustion is performed using the air outside the ventilation tube.

To explain with a diagram, +11 is the upper humidity control tank 1, the upper part of the tank (1) is formed into a funnel +21 F2+, and the end of the funnel +21 is a drying chamber (a

are formed respectively. A rotary valve +61 +61 is attached to the lower end of the drying chamber +31 +31, and the valve +61 (surrounded by a receiving gutter (7) on the lower side of 61,
A screw conveyor (8) is installed horizontally at the upper center of the receiving trough (7), and the grains transported horizontally by the conveyor (8) are fried by an elevator and then stacked and returned to the humidity control tank fl1. 1st
The cross-section shown in the figure is shown in FIG. 2, where a ventilation tube (9) is provided at one end of the hot air supply chamber (4), and a ventilation tube (9) is attached to the discharge side of the hot air exhaust chamber +51 +51. A suction fan aυ is installed in the exhaust pipe Ql, and when the fan OD rotates, hot air is circulated as shown by the arrow in FIG. The fan aυ is very powerful and is capable of blowing at least 2 rrl/sec of air per ton of unhulled rice. A gasification burner is installed inside the ventilation tube (9) as shown in FIG. At the center position inside the ventilation tube (9), there is a hanging tool αj provided inside the ventilation tube (9).The ventilation tube α2 is formed with a much smaller diameter than the inner diameter of the ventilation tube (9). (The above-mentioned hanging tool α may be omitted. In other words, it can also be used as a support by the blowing cylinder, which will be described later). The rear half of the blower cylinder O3 is a horizontal cylinder, and the front half is formed to become thinner as it reaches the tip (front end).

A vertical mounting plate aS is provided inside the blower tube O3, and a motor a71 having a much smaller diameter than the blower tube Oz is fixed to the center of the mounting plate ne. A plurality of through holes aS are bored in the mounting plate QG. The rotation axis a9 of the motor αη extends horizontally forward and protrudes forward beyond the tip opening Q5, and the heating gutter (A) is fixed to the tip. Heated bowl (
A) has a shape facing rearward, and surrounds the outer periphery of the tipper part α by forming a gap QB. Rotating axis■
A conical part (diffuser) is attached to the bottom of the heating bowl (a) at the tip of the heating bowl (a), the diameter of which gradually increases as it reaches the bottom between the heating arms. (C) is a kerosene supply device, which extends toward the inside and front of the blow tube 03, and its tip is open above the conical portion.

The base (to) of the tipper part α is fixed to the blower cylinder O2, and the base of the outer cylinder (c) is also fixed thereto. The outer cylinder (C) largely surrounds the outside of the heating bowl (■). A blowing tube (c) is attached to the side wall (to) of the blowing tube 02 in FIG. 3, the other end of the blowing tube (c) is connected to the opening (to) of the ventilation tube (9), and the opening ( Install a blower that can be viewed from a centrifugal fan on the outside of the (to) is a combustion plate, OD is a ceramic heater, (to) is a gasification chamber, and (to) is a combustion chamber. FIG. 4 shows another embodiment, showing the right side view of FIG. 3, and shows that the hanger (11) is the same in that the air blower wIIα2 is suspended, but the blower (c) is replaced with the ventilation tube ( 9), and its suction pipe (to) opens to the outside of the ventilation tube (9), and is formed to suck air from outside the ventilation tube (9). (C) is a blower. It is a variable motor that rotates the

Next, I will explain the effect.

Although the diagram is omitted, when undried rice is supplied to the loading port of the elevator, the undried rice is fried by the elevator and fed into the humidity control tank (1), where it falls under its own weight and is then dried in a down-flow type. room +

Supply drying air at 2 m/sec or more. Further, the motor αη that rotates the heating bowl (support) and the variable motor (to) of the blower (c) are also energized to rotate the heating bowl (support) and the blower. Therefore, when the kerosene supplied by the kerosene supply device is dropped onto the conical part @, which rotates at 2,500 revolutions per minute, it is stirred as if being blown away by centrifugal force, and the heating bowl (
It reaches the inner surface of 1) and is violently agitated, becoming like a mist within the gap QD. There, the air blown from the blower (c) is blown into the air by blowing m@→blow tube 0ri→through hole aS→gap C! Since the amount of air corresponding to the amount of kerosene is blown through υ, the kerosene that has become a mist is gasified and becomes a completely mixed gas in the gasification chamber (to), which is then blown outward from the combustion plate (to). Inject into the (front) combustion chamber (toward). Therefore, ceramic heater-C (
If you apply electricity to +1, it will easily ignite and burn just like regular gas. The flame thus causes the outer surface of the heating bowl to become red hot. Then, the kerosene in the gap Qυ on the inner surface of the heating bowl (7) becomes more and more actively gasified, and finally burns as a blue flame.

Therefore, the hot air with the n-color flame is supplied from the hot air supply chamber (4) to the downstream drying chamber +31 (31) to dry the grains.
Unlike traditional red flame, it does not reduce grain quality. However, dry grains are removed by rotating valve +61 (61
The grains are dropped little by little onto the receiving gutter (7) by the simultaneous rotation of the grains, collected by the screw conveyor (8), lifted by an elevator, and stacked on top of the humidity control tank fll. This circulation drying is done for 5~
After repeating this process about 6 times, the unhulled rice will be completely dry. This kind of work will make the blue flame smaller. Even if the blue flame is small, it will not disappear because the combustion air of the present invention is sent by a dedicated blower.

Conventionally known grain drying apparatuses include, for example, the Japanese Utility Model Application Publication No. 55-646.
As described in Publication No. 22, a fan (0υ in the embodiment of the present invention is used for this purpose) that ventilates the combustion air for kerosene that has been atomized by a heating bowl installed in the ventilation cylinder inside the ventilation cylinder. (applicable) was also used. That is, the burner was used to cause combustion using the air passing through the ventilation tube. With this kind of structure, when the flame was made small, strong winds entered the fire, so there was a risk of a misfire.

However, in the present invention, the heating bowl (1) for rotating and stirring kerosene is installed in the ventilation tube (9), and the blower (to) for supplying combustion air to the heating bowl is connected to the ventilation tube (9). A vaporizing burner that is installed outside the ventilation tube (9) or installed inside the ventilation tube (9) and whose suction tube is opened to the outside of the ventilation tube (9) so that combustion is performed by the air outside the ventilation tube (9). Because of the configuration, although one extra blower mortar is required, it can send air commensurate with the amount of kerosene needed, so hot air can be formed with blue flame, and high quality dry grain can be obtained. Not only is this possible, but it also has the effect of preventing misfires even when the blue flame is small.
