Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a radiant heating device for agricultural and livestock production, which is used for warming livestock, drying grain, and the like.

(Prior art) A radiant heating device for agriculture and livestock uses, for example, a Bunsen gas burner to heat a radiant body such as a skeleton or a radiant plate, and uses the radiant heat to heat or dry the object. It is.

In conventional such devices (for example, see Utility Model Publication No. 57-56025 and Japanese Unexamined Patent Publication No. 57-77808),
The gas burner is installed in a vertical shape below a reflector plate with the burner head side provided with flame holes on the upper side and the primary air suction section on the lower side, and a radiant plate etc. is provided on the reflector plate corresponding to the flame holes. There is.

(Problem to be solved by the invention) For this reason, the gas burner body, gas supply pipe, etc. are located on the radiation side of the heat from the radiant plate and the reflector, so they block the radiation, and therefore the shadow of the radiation is This makes uniform radiant heating difficult, and there is also the problem that gas supply pipes and the like are overheated.

In addition, radiant heating equipment for agriculture and livestock production is generally installed in dusty locations, so depending on how the burner is installed, dust can easily accumulate inside, and there is a risk of incomplete combustion if dust accumulates. Therefore, countermeasures are necessary.

The present invention aims to solve the above-mentioned problems.

(Means for Solving the Problems) To explain the means for solving the above problems with reference to the drawings corresponding to the embodiments, the radiant heating device for agricultural and livestock farming of the present invention has flames radiating on the circumference. A Bunsen gas burner 2 equipped with a burner head 10 having holes 3 is installed vertically through the center of the umbrella reflector 1, with the burner head 10 side positioned below the center of the umbrella reflector 1. At the same time, the primary air suction section 5 side is positioned above the umbrella-shaped reflector plate 1, and a radiant plate 4 is provided below the umbrella-shaped reflector plate 1 in correspondence with the outer upper side of the flame hole 3. The bottom part 11 of 10 is configured to be inclined diagonally downward together with the flame hole 3.

(Function) In the above configuration, when fuel gas is ejected from the gas nozzle 6 in the direction of the primary air suction section 5, air is sucked into the primary air suction section 5 by the ejection energy and mixed in the mixing section 7. While doing so, it reached flame holes 3 and 3, and it erupted from there and burned, creating flame 8.
form. The flame 8 thus heats up the radiation plate 4, and radiates heat directly from there and then reflected by the umbrella-shaped reflection plate 1 and downward.

In this case, in the gas burner 2, the burner head 10 provided with the flame holes 3 is located below the umbrella-shaped reflecting plate 1, and the primary air suction part 5 is located above the umbrella-shaped reflecting plate 1. , there is no part formed below and in the lateral direction of the flame hole 3 that blocks the radiation from the radiant plate 4 and the umbrella-shaped reflector plate 1, so that no radiation shadow is produced, and uniform radiant heating is possible. Overheating of gas supply members such as the gas nozzle 6 can also be prevented. Further, since the flame hole 3 is configured to be inclined diagonally downward, the flame 8 can be spread laterally, and the radiant plate 4 can be efficiently heated to red heat over a wide range.

Since the bottom part 11 of the burner head 10 is configured to be inclined diagonally downward together with the flame hole 3, even if dust is sucked into the burner 2 from the primary air suction part 5 during use, it can easily escape from the flame hole 3 to the outside. It is difficult for air to accumulate on the bottom 11, and even if it does, it can be removed by washing with water by supplying water from the upper primary air suction section 5.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

In the figure, numeral 1 is an umbrella-shaped reflector,
2 is a Bunsen type gas burner. The Bunsen type gas burner 2 has a burner head 10 with flame holes 3 arranged in a radial direction on the circumference, and the bottom 11 of the burner head 10 is inclined diagonally downward together with the flame holes 3.

The Bunsen type gas burner 2 having the above configuration is installed in a vertical shape by penetrating the center of the umbrella-shaped reflector 1, and the burner head 10 side is connected to the umbrella-shaped reflector 1.
The primary air suction section 5 side is located above the umbrella-shaped reflecting plate 1. In order to have such a configuration, a through hole 9 is formed in the center of the umbrella-shaped reflecting plate 1, through which the mixing section 7 of the gas burner 2 can pass. Further, a radiating plate 4 is provided on the lower side of the umbrella-shaped reflecting plate 1 and above the outside of the flame hole 3. The radiation plate 4 is made of a wire mesh, a perforated plate, etc., and is heated by the flame formed by the flame hole 3, and radiates the heat directly from there and downward by being reflected by the umbrella-shaped reflecting plate 1.

(Effects of the invention) As described above, the present invention has a Bunsen type gas burner as a radiant heating source that is vertically inserted through the center of the umbrella reflector so that the burner head side is located downward and the primary air suction part side is located upward. Since it is installed in a molded state, there is no part below the flame hole that blocks the radiation from the radiant plate and the reflector plate, so there is no radiation shadow, and uniform radiant heating is possible.
This also has the effect of preventing overheating of gas supply members such as gas nozzles. In addition, in this invention, the bottom of the burner head is tilted diagonally downward together with the flame hole, so even if dust is sucked into the burner from the burner air suction part during use, it can be easily removed from the flame hole to the outside. It is difficult for dust to be released and accumulate on the bottom, and even if it does accumulate, it can be removed by supplying water from the upper primary air suction section and washing with water, which prevents incomplete combustion due to accumulation of dust. There is an effect that it can be done.
