Description

[Detailed Description of the Invention] The present invention relates to a heating furnace used for heating and repairing horseshoes and other tools.

In general, horseshoes and other tools become worn, deformed, or fatigued when used for a long period of time, and therefore need to be replaced or repaired as appropriate.

For this reason, stable areas of racehorse training centers and large racetracks in urban areas in particular are equipped with furnaces for changing and modifying horseshoes and for heating and modifying tools. It is common for horseshoes to be provided.

In this shoeing shop, horseshoes and other tools are heat-processed and modified using a heating furnace.

Covered or semi-covered fire beds are often used in the heating furnaces of these dressing shops, and the structure allows for easy fire prevention and exhaust gas countermeasures.

The fuel used in this furnace is solid fuel such as coke or charcoal.

Due to the vast area of the stable areas of training centers and large-scale racing arenas in the suburbs of cities, when the horseshoes, etc. need to be renovated, we visit the farriers each time to renovate them. Doing so may cause inconveniences such as wasting training time and hurting the hoof.
Currently, many renovations are being carried out at locations other than farriers.

The conventional mobile heating furnace, which is easily used in places other than farriers, is called ``Kanteki'' and has a shape and structure that closely resembles that of a pair of shoes, and the heating material is also coke. Solid fuels such as charcoal are used.

Fig. 1 shows this cabinet. 1 is the cabinet main body, and a combustion chamber 2 is provided inside the main body 1 with its upper part open. An intake port 3 is formed, and air for combustion can be supplied to the blower 4 through an air introduction pipe 5.

Because of this structure, it is easy to move, and it is very good in that horseshoes can be refurbished and tools can be heated and repaired freely outside the farriery, but it has the following drawbacks: are doing.

First, since the grate is exposed, it is difficult to take measures to prevent combustion exhaust gas and fire.

This means that - this type of combustion has the disadvantage that combustion plumes, dust and harmful combustion exhaust gases (carbon oxides and carbon dioxide) are produced.

Therefore, using it in a small room is extremely dangerous for humans and animals.

Furthermore, since the fire bed is an exposed type, it is not preferable to use it in a place where combustible materials such as straw are present, such as a stable, from the standpoint of fire prevention.

Furthermore, as mentioned above, solid fuel is used in both the kanteki and the dressing shop furnaces.

Therefore, it is not easy to ignite this fuel, and combustion cannot be freely controlled.

In this way, since the heating temperature cannot be controlled freely,
The surface of the horseshoe, etc. burns due to overheating, and when the horseshoe, etc. is being repaired, the surface peels off and becomes an iron skin, which may fly off and cause burns to the worker.

The present invention was developed in view of the above-mentioned drawbacks.The combustion chamber is surrounded by a fire-resistant furnace wall, and this furnace wall is equipped with a door that can be opened and closed to take in and take out horseshoes, etc., and an exhaust port for discharging combustion exhaust gas. A burner is provided on a part of the furnace wall, and the furnace inner wall facing the burner forms a furnace side on which horseshoes, etc. are placed, and the flame of the burner is directed from the bottom of the horseshoes, etc. It is an object of the present invention to provide a heating furnace that can eliminate the above-mentioned drawbacks of the conventional technology by providing a recessed portion that reflects the light upward.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

The combustion chamber A has a structure surrounded by a refractory furnace wall 21, and a burner 2 is installed approximately in the center of the upper furnace wall 21a of the combustion chamber A.
2 is installed so that it burns downward.

The bottom of the combustion chamber A (furnace wall 2.1b) has a furnace side 23 made of refractory bricks or the like having a recess or groove approximately in the center, on which a horseshoe or the like 24 can be placed and heated.

The width of the recess or groove is formed to be slightly narrower than the width of the horseshoe or the like 24, and the flame emitting port of the burner 22 faces the center of the width of the recess or groove.

The flame emitting port of this burner 22 is slightly narrower than the width of the U-shaped cutout of the horseshoe 24.

The height of this recess or groove is such that the flame emitted from the flame emitting port of the burner 22 passes through the U-shaped missing part of the horseshoe etc. The height is lower than the height at which the reflected light reaches the lower surface of the horseshoe, etc. 24.

The front furnace wall 21c of the combustion chamber 1 is hinged to the bottom furnace wall 21b so that it can be opened and closed freely, and a fireproof glass 25 is fitted into the center of the front furnace wall 21c so that the inside of the combustion chamber A can be monitored. It is.

Of course, it goes without saying that the front furnace wall 21c is closed and buttoned during combustion heating.

B, B'U This is a locking member used when closing and controlling the front furnace wall 21c.

In addition, an exhaust port 26 for discharging combustion exhaust gas is provided on the rear furnace wall 2id, from which the exhaust gas is discharged to the outside.

The burner 22 is detachably connected to a gas cylinder 29 via a hose 27 and an air conditioning device 28, so that fuel gas can be supplied to the burner 22.

The pressure gauge 30 is attached to the outlet of the gas cylinder 29.
Based on the pressure of this pressure gauge 30, the amount of gas supplied to the burner 22 can be adjusted by adjusting the cock (2) of the gas cylinder 29.

Furthermore, the furnace wall 21 has a thickness of, for example, 5 [sennanometers].
The fireproof board 21y is fixed to the inside of the iron plate 21z, and the mechanical strength is mainly provided by the iron plate.

Next, the operation of this embodiment will be explained.

First, the front furnace wall 21c of the combustion chamber 1 is opened, and the horseshoes, etc.
is placed on the furnace side 23 having a recess in the center, the cock V of the gas cylinder 29 is opened, and the burner 22 is immediately ignited using a side winder torch or the like.

Next, the front furnace wall 21c is closed, and the air conditioning device 28 is adjusted to bring the flame of the burner 22 to an optimal state.

The burner 22 used here is for medium pressure.

One minute after ignition, 2.40 heads of horseshoes, etc. turn dark red (
After about 2 minutes, the parts from the horseshoe etc. 24 to the sides are heated to a red color (about 900°C), and after 3 minutes, the entire horseshoe etc. 24 turns yellow (about 1000"C). 5
D The iron lip is heated to a sufficient temperature for unrolling and repair work.

Therefore, at this point, it is sufficient to open the front furnace wall 21c, take out the horseshoe etc. 24 from the combustion chamber A, and perform repair work.

The fact that the horseshoes, etc. can be heated in such a short time is that the flame of the burner 22 directly hits the horseshoes, etc. 24 placed on the large side 23, as shown in FIG. This is because the heat is reflected by reaching the formed recessed part of the furnace side 23 and circulates from the bottom of the horseshoe, etc. to the upper side, thereby uniformly heating the entire horseshoe, etc.

As previously mentioned, since this burner 22 is of medium pressure type, the maximum temperature does not exceed 1200° C., and it is possible to prevent the horseshoes, etc. 24 from burning due to overheating.

Also, the upper surface of the horseshoe etc. 24 is
The flame of the burner, which passes through the missing part, deviates from the center and spreads around the U-shaped missing part of the horseshoe, etc. 24, and is heated with a slightly weakened flame, so the strong flame at the center of the flame spreads. This prevents only the surface from being heated rapidly.
Therefore, the phenomenon in which only the surface of the horseshoe or the like becomes an iron skin and peels off is avoided, and the entire inside of the furnace is heated strongly.
The inside of the horseshoe is heated almost uniformly.

In addition, the lower surface of the horseshoe, etc. 24 passes through the U-shaped notch in the center of the horseshoe, hits the furnace wall, is reflected, and is heated by a slightly weakened flame, so only the surface is heated rapidly. This avoids the phenomenon that only the lower surface of the horseshoe, etc. 24 becomes a skin and peels off, and the entire inside of the furnace is heated, and the entire horseshoe, etc. 24 is heated almost uniformly inside the furnace. Ru.

Furthermore, the fuel may be gas or liquid, and therefore combustion control can be easily performed, making it easy to adjust the temperature within the combustion chamber A, and tools other than horseshoes to be heated and modified.

Normally, when the device is used indoors, an exhaust conduit may be connected to the exhaust port 26 to guide the exhaust gas to the outdoors.In this way, it is of course possible to use the device indoors.

In addition, the present invention has a structure in which the burner 22 is provided on the side of the furnace wall, four shelves 23 having recesses are formed on the opposing surface, and locking tools such as horseshoes are provided on the four shelves 23. It is okay to do so.

As described above, according to the present invention, the combustion chamber is surrounded by a fire-resistant furnace wall, a burner is provided on the furnace wall, and four shelves on which horseshoes, etc. are placed are formed on the inner furnace wall facing the burner. ,and,
Since the four shelves are provided with recesses that reflect the flame of the burner in the entire circumferential direction of the horseshoe, etc., no combustion slag remains, no combustion smoke or dust is generated, and combustion control is possible, making it suitable for general use. Not only horseshoes, but also duralumin horseshoes and other tools can be heated and repaired.

Moreover, the upper surface of the horseshoe is away from the center of the strong flame,
Since it is heated with a flame that spreads outward and is slightly weakened, only the upper surface is not heated rapidly, and the phenomenon of only the upper surface of the horseshoe becoming an iron skin and peeling off is avoided.

In addition, the lower surface of the horseshoe passes through the recesses of the four shelves, is reflected by the refractory furnace wall, and is heated by a slightly weakened flame.
Only the lower surface is not heated rapidly, and the phenomenon of the surface becoming a skin and peeling off is avoided, and the inside of the horseshoe is evenly heated.

Furthermore, since the combustion chamber is covered, it has the advantage of being able to prevent harmful exhaust gases and prevent fires, and also has the advantage that it is easy to take horseshoes and the like into and out of the furnace.

Furthermore, various effects such as ease of transportation and movement 4.
