Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a heat dissipation device for agricultural and livestock production used as a brooder or the like.

(Prior art) As a heat dissipation device for agricultural and livestock farming used as a brooder, etc., an inverted truncated cone-shaped red-hot part made of skeleton or the like is provided in the lower central part of the top plate as an umbrella-shaped reflector, and A burner with an annular flame opening is installed at a predetermined distance below the red-hot part, or a reflector on the upper side and a perforated plate on the lower side are installed so as to form a space between them. to form a red-hot part in the shape of an inverted truncated cone, the burner is provided with a flame port so as to eject flame laterally and radially, and this flame port is sandwiched between the reflective plate and the perforated plate. There is a method that does this.

Heat dissipation devices for agriculture and livestock farming are generally installed in places with a lot of dust, and in the latter configuration, dust tends to accumulate on the perforated plate that makes up the red-hot section, so measures are needed to prevent this, whereas in the former configuration, Since there is no part where dust can accumulate in the red-hot part of the configuration, such measures are unnecessary. Moreover, the former configuration has advantages over the latter configuration in that it is easier to install the burner, it is easier to install it in a detachable manner, and the supply of secondary air to the flame is better.

The present invention relates to a heat dissipation device for agricultural and livestock farming having the former configuration which has such advantages.

Conventional heat dissipation equipment for agriculture and livestock with such a configuration not only ensures good combustion by supplying sufficient secondary air during high-flame combustion, but also ensures that the large flame at that time efficiently heats the red-hot part. In order to achieve this, the red-hot part and the burner's flame opening are placed a predetermined distance apart.

(Problem to be solved by the invention) Since the red-hot part and the flame opening of the burner are installed a predetermined distance apart, the red-hot part cannot be sufficiently heated by a small flame during low-flame combustion. Therefore, heat loss is large and infrared radiation efficiency is poor.

The present invention aims to solve such problems.

(Means for Solving the Problems) Means for solving the above-mentioned problems will be explained with reference to the drawings corresponding to the embodiments. In a heat dissipation device for agricultural and livestock farming, an inverted truncated cone-shaped red-hot part 2 is provided at the center of the side, and a burner 3 having a flame opening part 4 arranged in an annular shape is installed below the red-hot part 2 at a predetermined distance. ,
A cylindrical red-hot net 5 is attached above the flame port 4 of the burner 3.

(Function) In the above configuration, as shown in FIG. 4a, during high-flame combustion in the burner 3, the large flame efficiently heats the red-hot part 2 and radiates infrared rays from there. At this time, the cylindrical red-hot net 5 is also heated and becomes red-hot,
It also emits infrared rays.

Next, as shown in Fig. 4b, during low-fire combustion in the burner 3, the flame is small and the red-hot part 2 cannot be sufficiently heated. The shaped red-hot net 5 is sufficiently heated to become red-hot, and infrared rays are radiated from there.

In this way, even a small flame during low-fire combustion can contribute to the radiation of infrared rays by the cylindrical glowing net 5, and since the cylindrical glowing net 5 is a net, it does not interfere with the supply of secondary air. Does not worsen flammability. In this way, heat loss can be reduced, infrared radiation efficiency can be improved, and operation with a low amount of radiation can be stably performed.

(Example) Next, to explain the illustrated example, first, the burner 3
A slit portion 7 for a flame opening is provided on the outer periphery of the burner head 6,
In addition to arranging small holes 8 for a flame outlet in an annular manner on the inner periphery,
A ring-shaped protrusion 9 is provided between the slit part 7 and the flame opening small hole part 8, and the cylindrical glowing net 5 is attached to the outside of the ring-shaped protrusion 9. The burner 3 has a structure in which the amount of combustion is adjusted by a radiation temperature adjustment section 11 to vary from high flame to low flame, thereby adjusting the amount of infrared radiation, and is also configured to be easily attached and detached. In addition, the red-hot part 2 made of skeleton or the like is provided with a large number of protrusions 10, and a layer of far-infrared emitting material is formed by painting or thermal spraying to increase the radiation efficiency.

(Effects of the invention) As described above, the present invention is a radiation device for agricultural and livestock farming that has advantages in terms of dust and combustibility, that is, it consists of a skeleton or the like in the lower center of the top plate as an umbrella-shaped reflector. In addition to providing a red-hot part in the shape of an inverted truncated cone,
In an agricultural and livestock radiator system in which a burner with an annular flame opening is installed at a predetermined distance below the incandescent part, a cylindrical incandescent net can prevent even a small flame during low-flame combustion. It is possible to contribute to infrared radiation without deteriorating combustibility, reduce heat loss, improve infrared radiation efficiency, and stably operate with a low amount of radiation.
