Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a sulfur evaporation apparatus for controlling harmful birds.

[Conventional technology]

Conventionally, as a method of moving away or spelling off sparrows that damage rice, there are methods such as Sakaeko, visually appealing colors and constant movements, and making noise by making a sound.

[Problems to be solved by the device]

In the case of the method of visually appealing to Sakayamako and colors and shapes, the effect is effective in the early stage, but the sparrow becomes fragile within a short period of time.
There was a problem that the sperm sucked the endosperm.

Further, in the case of a method of producing a sound by using a carbide or propane gas, there is a problem of pollution due to the sound and it cannot be used.

Then, this invention aims at providing the sulfur evaporation apparatus which evaporates sulfur and controls a sparrow.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention is directed to a heater, a dish for storing an appropriate amount of sulfur and placing it on the heater, closing an upper opening of the dish, and downwardly from the upper edge of the dish. A lid whose lower surface on the entire peripheral edge that bulges toward the tank serves as a reservoir for carbon dioxide gas burned by a heater, and a passage provided so that the lower edge of the upper edge of the plate is higher than the peripheral edge of the lid. It is composed of and.

[Action]

When the bottom of the dish is heated by the heater, the sulfur in the dish melts into a liquid and then vaporizes to fill the dish closed by the lid.

The filled sulfur vapor flows out of the dish through the passage.

At this time, carbon dioxide gas generated by the combustion of the inside of the heater flows out from the upper edge of the heater to the outside, and along the outer peripheral surface of the dish, rises and fills the pool.

Therefore, even if the air tries to enter the inside of the dish through the space between the lid and the dish from the atmosphere, it is blocked by the carbon dioxide gas in the reservoir, and the molten sulfur in the dish does not catch fire.

It should be noted that the sulfur vapor in the dish travels along the back surface of the lid toward the peripheral edge of the lid, and when it reaches the peripheral reservoir of the lid, the temperature does not ignite and the atmosphere from the peripheral edge of the lid does not ignite. Is released.

〔Example〕

In the figure, reference numeral 1 is a heater, and a dish 2 containing an appropriate amount of sulfur A is placed on the heater 1. When the lower surface of the dish 2 is heated by the heater 1, the inside of the dish 2 Sulfur A
Melts into a liquid and then vaporizes.

In the above-mentioned heater 1, the solid fuel 4 is burned in the non-combustible container body 3 whose upper surface is open in the case of the drawing, but the lower surface of the non-combustible dish 2 is heated by a method other than the above. You may

Further, the upper surface opening of the dish 2 is closed at its entire peripheral edge by a lid 5 protruding downward from the upper edge of the dish 2, and the lower surface of the peripheral edge portion of the lid 5 protruding is carbon dioxide gas for preventing ignition of sulfur. It is the pool part 6 of.

When the fuel is burned in the heater 1, air is taken in from the lower part of the ventilation part 8 provided in the heater 1 and carbon dioxide gas is released from the upper part of the ventilation part 8. Therefore, the released carbon dioxide gas is , Rises along the outer periphery of the dish 2 and fills the reservoir 6.

When carbon dioxide gas fills the reservoir 6, the dish 2 and the lid 5 are removed from the atmosphere.
Even if the air tries to flow into (invade) the dish 2 through the gap between the and, it is blocked by the carbon dioxide gas.

Therefore, there is no contact between the melted sulfur in the dish 2 and the air, so that no ignition occurs.

Further, the passage 7 of the sulfur vapor from the inside of the dish 2 toward the pool portion 6 is formed by providing the notches scattered around the entire upper edge of the dish 2, but is provided on the lower surface of the lid 5 (not shown). The portion may be brought into contact with the upper edge of the dish 2 and the gap between the lower surface of the lid 5 and the upper edge of the dish 2 may be used as a passage.

In any case, the lower edge of the passage 7 is located higher than the peripheral edge of the lid 5.

Also, as the amount of carbon dioxide accumulated in the reservoir 6 increases, the dish 2
Since carbon dioxide gas flows into the inside, the sulfur vapor that has accumulated on the back side of the lid 5 is pushed out, and the sulfur vapor is released from the passage 7 to the atmosphere.

At this time, the vapor that has reached the passage 7 does not ignite even if it contacts the atmosphere due to the decrease in temperature.

The sulfur evaporating apparatus configured as described above is used on the ground of a paddy field to prevent fine particles in sulfur vapor diffused in the atmosphere from adhering to rice and preventing sparrows from flying, and controlling each pest.

〔effect〕

As described above, by using the sulfur evaporation device of the present invention in a paddy field, it is possible to prevent sparrows from flying.

Further, the peripheral edge of the lid is protruded outward from the peripheral edge of the dish, and the lower surface of the entire peripheral edge that is protruded is used as a carbon dioxide reservoir, so that the carbon dioxide accumulated in the reservoir causes the gas to enter the dish. Ingress of air is blocked.

As a result, the ignition of molten sulfur can be prevented, and the lid can be used even during rainfall.
