Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is capable of stably and sufficiently supplying air into an incinerator, and reducing power consumption of a blower and a compressor for supplying air to reduce the power consumption. The present invention relates to an air supply device for a furnace body that can be downsized as a whole.

[Conventional technology]

Conventionally, a plurality of openings are formed in the wall surface of the combustion chamber in the furnace body, and by operating a blower installed outside the furnace body in the openings, air ejected from this blower is connected to the blower by a pipe body. The tip of the tube body is inserted into the opening to supply air into the furnace body.

[Problems to be solved by the device]

However, in this blower, although there is no problem in the amount of air supplied, there is a problem in that the air supply pressure is low,
As a result, there are problems such as uneven combustion and a long combustion time, and incomplete combustion.

Therefore, although the supply pressure was increased by increasing the size and size of the blowers, the electric power for operating the blowers naturally increased. However, it is good if the incinerator is installed in a place where a large amount of electricity can be used, but in places where a large amount of electricity cannot be used, such as in-vehicle incinerators and incinerators used in the mountains Since the electric power is generated using a machine, it is not possible to freely increase the size and number of blowers, which limits the amount of electric power.

Therefore, for example, when considering an in-vehicle incinerator,
Even if the generator of the car itself or an on-vehicle generator is loaded, the air supply pressure will be about 0,20 kg / cm ^2, and the combustion time should be lengthened to completely burn the incinerator at this level of air supply pressure. There was nothing else.

Therefore, in order to increase the air supply pressure, the air supply pressure is set to 5
kg / cm ² but was also considered to use a certain degree compressors, in the case of this compressor, the amount of air that the air supply pressure is sufficient that there is a problem that insufficient.

Furthermore, we also considered installing a blower and a compressor separately and using them together, but it is difficult to adjust the supply amount and supply pressure of air respectively according to the combustion state in the furnace body,
Moreover, it was not possible to stably supply air.

The present invention is intended to solve the above problems, and can stably and sufficiently supply the air to be supplied into the furnace body, and the power consumption of the blower and the compressor for supplying the air can be small, so that the incinerator for a vehicle, etc. It is intended to provide an air supply device for a furnace body that can be used even in a place where power consumption is limited.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention fits a lid body having an opening at the center to the base end of a cylindrical body with a thin tip, and blows from a blower to the base side wall of the cylinder body. The outer tube connected to the feed tube for guiding the air into the cylinder and the opening in the lid, the compressor is connected to the base end, and the tip of the outer tube is the tip of the cylinder. Of the furnace body, which is located closer to the base end than the inner tube, has an outer diameter smaller than the inner diameter of the cylinder, and is slidable in the length direction of the center line of the cylinder of the outer tube. With the air supply device as the gist, a spacer is installed on the outer surface of the inner tube and the inner surface of the inner tube of the outer tube so that the inner tube is positioned on the center line of the outer tube and slidable in the length direction. It is also possible to provide a valve that can adjust the amount of air from the blower as a spacer. Further, the inner diameter of the inner tube and the inner diameter of the outer tube are at least 1: 3 or more, and the inner diameter of the outer tube and the inner diameter of the outer tube are set to 1: 2. The inclination angle of the tip of the cylindrical body is set to about 30 ° with respect to the center line of the cylindrical body, and a state where the effect of stabilizing the supply air is good is introduced. Also, the feed pipe may be formed so as to be inclined in the proximal direction of the outer pipe, or between the lid and the outer pipe,
It is also conceivable to interpose a packing made of asbestos, rubber or the like.

[Action]

In the present invention configured as described above, a large amount of low-pressure air ejected from the blower is fed from the base end to the tip inside the cylinder of the outer pipe and outside the inner pipe through the feed pipe. It

On the other hand, a small amount of high-pressure air ejected from the compressor is sent from the base end to the tip inside the inner pipe.

The high-pressure air from the compressor is vigorously ejected from the tip of the inner tube to the outside of the inner tube, and is once ejected to the outside of the outer tube through the tip of the outer tube inside the cylinder. The large amount of low-pressure air staying near the tip is pulled and ejected out of the outer tube.

〔Example〕

An embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is an explanatory view showing a state in which the device of the present invention is installed in a vehicle furnace body, and a conventional vehicle furnace body 2 as shown by a one-dot chain line is placed on the loading platform of the vehicle 1. Then, a plurality of through holes 4 are formed at appropriate places in the side wall 3 of the furnace body 2, and the outer tube and the inner tube of the device of the present invention are inserted into the through holes 4 so as to face the furnace body.

That is, as shown in FIG. 2, a lid 7 having an opening 6 formed at the center is externally fitted to the base end of a cylindrical body 5 having a thin tip, and the side wall 8 of the cylindrical body 5 at a proper position on the base end side is fitted. Is an outer pipe 11 formed by connecting a feed pipe 10 for guiding the air blown out from the blower 9 into the tubular body 5, and the outer pipe 11 is penetrated through the tubular body 5 on the side wall 3. The hole 4 is inserted toward the inside of the furnace body 2.

Further, asbestos, rubber or the like is provided between the lid body 7 and the tubular body 5 of the outer tube 11 in the center thereof to have an opening substantially the same as the outer diameter of the inner tube, which has the same shape as the cross section of the tubular body 5. By interposing the formed packing 12, the air inside the cylindrical body 5 is prevented from leaking from the opening of the lid 7.

Furthermore, it is desirable that the tip of the tubular body 5 of the outer tube 11 be inclined at 30 ° with respect to the centerline 13 in the lengthwise direction of the tubular body 5 shown by the alternate long and short dash line in the figure. Tip edge to slanted end a
As a result of experiments, it has been proved that the length up to 10 to 15 mm is preferable, and the feeding pipe 10 is connected to the outer pipe 11
It is conceivable that the air of the blower 9 is smoothly fed into the tubular body 5 by inclining to the base end side and connecting to the tubular body 5 of the outer tube 11.

The tubular body 5 of the outer tube 11 thus formed is inserted into the through hole 4 to set the tip edge of the tubular body 5 to be substantially flush with the inner surface of the side wall 3, and then the outer tube 11 is attached to the outer surface of the side wall 3 by a bolt or the like. In order to prevent the air inside the furnace body 2 from leaking out of the furnace body 2 through the gap between the cylinder body 5 and the through hole 4, the base body portion of the gap between the cylinder body 5 and the through hole 4 is welded, It is attached by sealing or the like.

In addition, reference numeral 14 in the drawing indicates that the compressor is inserted into the opening 6 of the lid 7, the compressor 15 is connected to the base end, and the tip is closer to the base end than the tip of the tubular body 5 of the outer tube 11. Located in
The center line of the tubular body 5 has an outer diameter smaller than the inner diameter of the tubular body 5.
The inner tube is slidable in the length direction while being located on the same center line as that of 13.

Then, the center of the inner pipe 14 is positioned on the center line 13 of the cylindrical body 5 so that the inner pipe 14 can be slid in the length direction. One of the supports 16 connected to each other is fixed to the outer surface of the inner tube 14 or the inner surface of the cylindrical body 5, or the inner tube having an outer diameter slightly smaller than the inner diameter of the cylindrical body 5 as shown in FIG.
14 a plurality of supports on a ring-shaped member 17 having an inner diameter larger than the outer diameter, and a ring-shaped member 17 'having an outer diameter smaller than the inner diameter of the ring-shaped member 17 and having an inner diameter slightly larger than the outer diameter of the inner pipe 14. After inserting the inner pipe 14 into the smaller ring-shaped member 17 'of the spacer 18 on which the 16 is installed, the ring-shaped member 17' and the inner pipe are fixed by welding or the cylindrical body 5 and the ring member 17 are fixed. It is possible to fix and.

By mounting the apparatus configured as described above on the furnace body 2, as shown in FIG. 4 (a), a low pressure and a large amount of air ejected from the blower 9 passes through the feed pipe 10 and is indicated by an arrow in the figure. As described above, the inside of the inner tube 14 is fed from the base end toward the tip in the cylindrical body 5.

On the other hand, a high pressure and a small amount of air ejected from the compressor 15 is vigorously fed through the inner pipe 14 from the proximal end to the distal end. However, since the air jetted from the tip of the inner tube 14 is once fed into the furnace through the tip of the tubular body 5, the tubular body 5
Air is ejected from the tip of the outer tube 11 while attracting air in the vicinity of the inside of the tip, and as a result, high pressure and a large amount of air can be fed toward the center of the furnace. In addition, it is necessary to adjust the air to be fed depending on the combustion condition in the furnace. At that time, slide the inner pipe 14 toward the base end side as shown in Fig. 4 (b) or (c). As a result, the tip moves to the base end side, so that the pressure of the air ejected from the tip of the outer tube 11 is weakened, and it becomes easy to adjust.

However, a control valve 19 for adjusting the amount of air may be provided in the middle of the supply pipe 10 and the inner pipe 14, but in the case where the amount of electric power is limited, the furnace can be used as effectively as possible. Since it is required to supply air to the valve 19, adjusting the valve 19 causes a decrease in the amount of air, which is not preferable, and it is preferable to use it in the case of fine adjustment.

[Effect of device]

In the device of the present invention configured as described above, a small amount of high-pressure air sent from the compressor passes through the inner pipe, once passes through the cylinder, and then is ejected from the outer pipe tip. Since a large amount of low-pressure air from the blower passing through the passage outside the inner pipe inside the outer pipe is mixed and attracted at the tip portion inside the outer pipe, it is possible to send a large amount of high-pressure air into the furnace. is there.

Further, in adjusting the supply air, the supply pressure can be gradually decreased by sliding the inner pipe to the base end side, and the adjustment can be easily performed, and the air amount does not decrease. Therefore, there is no shortage of air volume.

However, it is possible to adjust the amount and pressure of air to be supplied by lowering the driving force of the compressor and blower, or by installing a valve in the middle of the supply pipe. For example, it is possible to adjust the pressure of the air to be sent while maintaining the driving power of the compressor and blower at the optimum output state, so the power consumption of the compressor and blower can be small. It can be used from an on-vehicle battery without using a machine, etc., and can be incinerated in a place without a power source, such as in the mountains. or,
Since the conventional blower had a low pressure, carbon generated in the furnace was inserted into the multiple holes formed in the furnace body, resulting in clogging.However, this device generates a high pressure. Therefore, the clogging of the opening at the tip can be blown away.
