Description

[Detailed description of the invention] [Industrial application field] This invention relates to a heating brooder used when raising chicks, livestock offspring, etc.

[Prior Art] Gas-fired brooders are widely used for heating inside buildings for rearing chicks, etc., but conventional gas-fired brooders have a combustion air supply near the combustion part of the gas burner. There is an intake port,
The air inside the building was being used as combustion air.

[Problems that the invention aims to solve] However, there was a problem in that the air filter attached to the air supply section was easily clogged because the inside of the building was full of dust made of chick feathers, etc. . Further, since the conventional brooder is used exclusively for heating purposes, it is unnecessary in the summer, which is wasteful.

[Means for Solving the Problems] In order to solve the above problems, the present invention has the following configuration. That is, the brooder according to the present invention includes a gas burner-type combustion section and an air supply section that supplies combustion air to the combustion section, and the brooder includes a brooder in which the combustion section is installed in a building for rearing chicks and the like. , the air intake port of the air supply section is provided outside the building.

[Function] Since the air intake of the air supply section is located outside the building, clean air is taken in as combustion air, the air filter of the air supply section is less likely to get clogged, and the gas burner of the combustion section is always in good condition. It is possible to maintain a good combustion condition. In addition, by discharging only air when the burner is extinguished, clean air can be introduced into the building, so it can be used for ventilation and cooling inside the building.

To install it, place the combustion plate 3 on the lower side of the stepped portion 22, and attach the hook portion 24 of the hook-shaped presser metal fitting 24.
A is brought into contact with the front peripheral edge of the combustion plate 3 and fixed with a rivet 27 inserted into a rivet hole 26 of the flange. In addition,
A cotton-like heat-resistant packing 28 is filled in the space between the end surface of the combustion plate 3 and the inner surface of the flange 23. The presser metal fitting 24 has a bent portion 24b,
Moreover, since it has elasticity, the packing 28 can be filled without any gaps, and sufficient airtightness and cushioning properties can be obtained.

A fuel hose 30 is connected to the fuel gas inlet 20 of the mixing chamber 13, and fuel is supplied into the mixing chamber 13 through this fuel hose 30. Reference numeral 31 in the figure is a knob for adjusting the flow rate. Further, 33 is a safety device that closes the gas valve when the flame goes out, 34 is an igniter, and 35 is a terminal box.

Next, the air supply section 1b includes an air intake member 40 having an air intake port 44, an air cleaner 41 attached to the mixed gas chamber 13 of the combustion section 1a,
and the air cleaner 41 and air intake member 40
It is provided with a connection hose 42 for connecting to. Near the air intake port 44 of the air intake member 40, there is a wire mesh spot 4 for removing relatively large foreign objects such as insects.
5 is posted. An angle 46 for attachment is provided on the side surface of the air intake member 40. The connection hose 42 is a bellows-type flexible hose that connects the lower part of the air intake member 40 and the air cleaner 41.
It is connected to the top of the. The air cleaner 41 is

FIG. 7 shows an example of how this brooder 1 is used.
In a building 60 for raising chicks, chick brooding cages 61 whose upper and lower surfaces are made of wire mesh are arranged side by side in a state that they are suspended from the ground. On the ceiling of building 60,
A plurality of combustion parts 1a of the brooder 1 are attached to the horizontal bar 62 by hanging tools 10, and the air intake member 40 of each air supply part 1b is attached to the ceiling by an angle 46. Board 6
It is attached to 4. An air pipe 65 is provided in the ceiling of the building 60, and the air intake port 44 of each air intake member 40 is connected to the air pipe 65. Outside air taken in from a blower 66 installed outdoors is supplied into the air pipe 65.

During heating, the gas tank 31 is opened to discharge gas into the mixing chamber 13 from the gas hose 30, and the blower 66 is activated to send outside air into the mixing chamber 13. At this time, relatively large dust in the air is removed by the wire mesh spot 45 of the air intake member 40, and finer dust is removed by the air filter 51. Gas and air flow into the mixing chamber 13 from directions perpendicular to each other and are mixed while crossing each other, so that both can be mixed uniformly.
The mixed gas is completely mixed while passing through the ventilate tube 14 and is supplied through the opening 16 to the entire space 17 of the burner. The mixed gas passes through the fine holes 3a of the combustion plate 3 and is discharged to the surface side of the combustion plate 3, where it is combusted. It goes without saying that the gas opening/closing operations for each brooder may be performed all at once using the main handle.

In this way, this brooder 1 uses clean air outside the building as combustion air, so the air filter is less likely to become clogged and combustion can be carried out in good conditions. Furthermore, in the embodiment, air is forcibly supplied to the combustion section 1a by the blower 65, so that sufficient air is reliably supplied to the combustion section 1a. Furthermore, by using outside air as the combustion air, it is possible to minimize the pollution of the air inside the building, which is favorable for the growth of chicks and animal offspring.

In addition, this Bruder 1 can be used as a ventilation system in the building and a cooling system in the summer by discharging only air into the building using the blower 65 when the gas supply is stopped and the fire is extinguished. can.

In addition, although the blower was used for supplying combustion air in the embodiment, air may be supplied by a blower device other than the blower.

[Effects of the invention] As is clear from the above explanation, the brooder according to the invention uses outside air as combustion air, so the air filter is less likely to become clogged and combustion can be maintained in good condition. At the same time, by discharging only air when the fire is extinguished, it has become possible to use it for ventilation or cooling.
