Description

[Detailed description of the invention] The present invention relates to a rice husk dust collection and combustion apparatus.

In communal drying and preparation facilities (country elevators), etc.
Since a large amount of raw material paddy is dehulled by a large huller and then air sorted, a large amount of dust-laden air is generated.

At this time, the rice husks are either air-transported to a rice husk storage by the sorting air and stored, or are processed in an attached incinerator, which causes a large amount of dust to fly around each device, extremely deteriorating the working environment.

Therefore, the present invention provides the above-mentioned method by stacking and integrally forming a rice husk dust collection device that forms a rice husk layer filter using the rice husks generated in the rice hulling process, and a rice husk combustion device having a funnel-shaped furnace. The sorting air (dust-containing air) from the rice hulling device is passed through a rice husk layer filter to collect the dust contained therein, and the purified air is released outside the machine to keep the working environment clean. A combustion furnace with paddy installed at the bottom (a high-performance furnace that discharges paddy downstream to simplify the replacement of the rice husk layer filter and improve work efficiency, and consistently mass-produces high-quality rice husk charcoal by burning the accumulated paddy) The aim is to develop and provide a new device.

The present invention will be explained with reference to embodiment figures.

FIG. 1 shows a rice husk dust collection/combustion device formed by stacking a rice husk dust collection device 1 and a rice husk combustion device 2 in an integrated manner.

The rice husk dust collection device 1 has a conveyor 3 for transporting rice husks placed horizontally on the upper part of the machine frame, and a plurality of rice husk chambers 4 inside the machine frame.
. . . and ventilation chambers 5 are arranged alternately (in parallel), and each boundary wall 6 . In addition, there are glass-like ventilation windows 8 on the outer wall on both sides of the machine frame.
8 are respectively provided, and a dust-containing wind and rain air pipe 10 is connected to an air outlet 9 provided on the other side wall.

The rice husk chamber 4 communicates the rice husk supply port 11 with the conveyor 3 at the top through a supply tube 12, and is provided with a rice husk discharge on-off valve 13 at the bottom of the chamber 4, and 14 is a rice husk layer filter formed in the rice husk chamber 4. , 15 is a rice husk flow down trough, which connects the upper end of the iron bridge to the rice husk conveyor 3, and has an on-off valve 23 at its lower end.

Further, the breathable wall body 7 may be appropriately selected from a woven net, a punched perforated plate, a louver, and the like.

Next, the rice husk combustion device 2 has a funnel-shaped furnace 16 made of a refractory material erected inside the machine frame, and has numerous groove-shaped ventilation holes 18 in the inclined wall portion 17 of the combustion furnace 16.・The ventilation hole 18... is connected to the intake chamber 19 formed in the machine frame, and the air intake port 20 of the intake chamber 19 and the exhaust fan 21 provided outside the machine are connected by the front 22. .

24 is the ignition window of the combustion furnace, 25 is a conveyor for carrying out combustion materials,
26 is a picture window, and 27 is a chimney.

According to the above-mentioned structure, the rice husks generated by the dehulling action of the rice hulling device are transferred to each rice husk chamber 4 via the carrying conveyor 3 at the top of the machine frame.
... to form a rice husk layer filter 14, respectively, and the dust-containing air generated in the hulling device is introduced into the ventilation chamber 5b via the ventilation pipe 10.

This wind passes through the rice husk layer filter 14 formed in each rice husk chamber 4 in the horizontal direction and flows out into the exhaust chamber 5a, and during this time, the dust contained in the dust-containing wind is removed from the rice husk layer filter 14.
4, and the exhaust air is discharged outside the aircraft as purified air to a level that is not inconvenient for practical use.

Next, the rice in the rice husk layer filter 14 that has absorbed the dust flows down to the combustion furnace 16 by opening the lower opening/closing valve 13 of the rice husk chamber 4 in a timely manner, and closes the opening/closing valve 13, and transfers the rice to the upper conveyor. 3, it is filled with new rice husks and renewed, and the dust collection operation continues.

On the other hand, the rice husk layer formed in the funnel-shaped combustion furnace 16 is formed by supplying the rice husk in the shortage from the rice husk flow down trough to form a predetermined amount of rice husk accumulation layer, and igniting the accumulated layer from the ignition window 14. At the same time, the combustion exhaust gas inside the furnace is
The rice husk charcoal is sucked out and removed from the furnace, and the rice husk charcoal is burned in the furnace, and the husked charcoal is taken out of the machine via the conveyor 25 for carrying out and left for the next process.

In this way, the rice husk dust collection/combustion device of the present invention allows the dust-containing wind to pass from the side through the rice husk layer filter formed in the rice husk chamber of the rice husk dust collector, and absorbs the dust contained in the wind. The purified exhaust air can be discharged outside the machine to keep the working environment clean, and its ventilation effect (thus, the rice husks are pre-dried and high-moisture rice husks can be burned). Since the combustion exhaust gas is sucked and removed through the numerous ventilation holes in the inclined wall of the funnel-shaped combustion furnace, clean hot air without ash is absorbed, making it convenient to use the hot air. Since it is integrated with a combustion device, it is possible to greatly improve the work efficiency through a rational integrated rice husk processing process, and mass production of high quality rice husk charcoal can be achieved easily and smoothly. It has the following effects.
