Description

[Detailed Description of the Invention] The present invention involves carbonizing the rice husk as a raw material by burning the volatile content in the rice husk obtained by carbonizing the rice husk (or organic waste such as straw waste) as a fuel source. This relates to improvements to the starting device for carbonization combustion equipment for rice husks, etc., which is capable of obtaining hot air for heating greenhouses, etc., or for drying grains, etc., and is concerned with improvements to the starting device for carbonization combustion equipment for rice husks, etc., which prevents the starting operation from interfering with the carbonization combustion action. (It is intended for rubbing.)

Next, to explain the embodiment in detail with reference to the drawings, in Fig. 1, A is a carbonization tank formed in a vertically long cylindrical shape, and the upper part stores the rice husks charged through the opening 1 provided on the upper surface side. The rice husks are formed in a storage section a for accumulation, and in an intermediate section following the storage section a, there is a carbonization section that heats and carbonizes the rice husks that flow down from the storage section a due to its own weight. A combustion section C is installed to burn the volatile gas in the rice husks.

The bottom part following the carbonization section a and the combustion section C accumulates smoky charcoal, which is the carbonization residue, which flows further down through the carbonization section, and the accumulated smoky coal flows from the storage section a to the carbonization section. It is formed in the smoky charcoal accumulation part d that regulates the amount of rice husk flowing down.

A storage part a formed in the upper half of the carbonization tank A has a guide funnel 2 installed in an opening opened to the top surface, and
The upper surface of the opening 1 is closed with a lid 5 having a chimney 3 and a rice husk supply tube 4.

The fuel part C installed in the middle part of the carbonization tank A includes a heating plate 1 arranged in an umbrella shape at the axial center of the inner cavity in the middle part of the carbonization tank A.
0 and the surface layer 11 of the rice husks (charred rice husks during operation) flowing down from the peripheral edge of the heating plate 10 according to the angle of repose α,
Combustion chamber 1 formed on the inside and bottom side of the heating plate 10
2, and a combustion tube 13 connected and communicated with the top of the umbrella-shaped heating plate 10 so as to communicate with the combustion chamber 12;
A heat insulating cylinder 14 is installed horizontally on the body of the carbonization tank A so as to surround the combustion cylinder 13, and a tip opening 15 is opened in the combustion chamber 12 so as to send air into the combustion chamber 12 from outside the carbonization tank A. It consists of an air supply pipe 16, etc., and a carbonization section,
It is formed at the upper surface side peripheral portion of the heating plate 10.

The volatile component gas generated in this carbonization section is passed through the trumpet-shaped opening 14a formed at one end of the heat insulating cylinder 14 to the open port 13 of the combustion cylinder 13, which is open to the outside.
By suctioning combustion gas from a, it is sucked into the combustion chamber 12 as shown by arrow W in FIG.

The fuel to be combusted in the combustion chamber 12 contains volatile components drawn into the combustion chamber 12 from the carbonization section, except at the time of startup until the heating plate 10 is sufficiently heated and carbonization begins. gas is used.

20 is a device for sucking this volatile gas into the combustion chamber 12, and a motor 2 is installed in the casing 21.
An axial flow blower is used in which an impeller 23 is pivotally supported by a transmission mechanism (not shown) driven by a transmission mechanism (not shown).
By placing an appropriate distance l between the opening 14a and the opening 14a of the combustion tube 13, the combustion gas is mixed with outside air and sucked in for heating, Further, the hot air at a desired temperature used for drying is blown out from the air outlet 25.

The smoky coal accumulation part d provided at the bottom of the carbonization tank A has a bottom plate that supports the smoky charcoal connected to the air supply pipe 16 communicating with the combustion chamber 12.
The rotating disk 30 has a scraping blade 31 for scraping the bottom surface of the layer of smoky coal deposited on the top surface of the rotating disk 30; is turntable 3
A scraping port 32 is provided to scrape off the scraped smoky charcoal to the lower side of the rotary plate 30.

Further, a ring-shaped gear 33 that protrudes outside the carbonization tank A is integrally formed on the circumferential surface of the rotary disk 30.
The ratchet pawl 34 engages with the ratchet pawl 3 and moves back and forth.

Reference numeral 40 denotes a rotation stopper for the smoked coal layer mounted above the rotary disk 30, and radial spokes 4 as shown in FIG.
1, and the boss portion 4 thereof is formed into a foil shape.
2 is fitted into the air supply pipe 16 described above, and the circumferential portion 43 is fixed to the carbonization tank A, so that the spokes 41 become buried in the smoldering coal layer, and the smoldering charcoal layer is removed from the rotary disk 30. We are trying to prevent it from following.

Reference numeral 50 denotes a hopper provided below the rotary table 30 to collect the smoky coal falling from the scraping port 32 provided on the rotary table 30, and an opening 51 at the lower end is provided with an air discharge port 53 of the blower 52. The conveying cylinder 56 for conveying the smoky charcoal under pressure is brought into communication by the pressure air blown from the nozzle 55 at the tip of the air supply pipe 54.

Reference numeral 60 denotes a starter device, and a vibro 1 that communicates with the carbonization tank A is provided at a portion of the cylinder peripheral wall of the carbonization tank A slightly lower than the heating plate 10 so as to project outward from the cylinder wind wall; It consists of a long guide vibro 2 that can be freely inserted into and removed from the vibro 1, and an ignition rod 63 provided on the guide vibro 2.

When starting the starting device 60, as shown in FIG. The tip is thrust into the combustion chamber 12 as shown in FIG.

Next, in this state, the ignition rod 63 whose tip is soaked in kerosene or the like and ignited is inserted into the combustion chamber 12 via the guide vibro 2 as shown in FIG. 4.

When inserting the ignition rod 63, if the tip of the ignition rod 3 gets stuck in the rice husks that have entered into the guide vibro 2, push the ignition rod 63 in a little forcefully to remove the guide vibro 2.
Since the rice husks inside flow out into the combustion chamber 12 which is a space, the ignition rod 63 is in a state where its tip is easily thrust into the combustion chamber 12.

Then, by continuing this state for a while, the ignition rod 63
The flames of kerosene, etc. impregnated with the impregnated material at the tip of the
The rice husks on the surface of the rice husk layer forming the inner wall surface of the combustion chamber 12 are ignited.

After ignition, the guide vibro 2 and the ignition rod 63 are pulled out.

This rice husk combustion device combusts the volatile gas carbonized from the rice husks in the combustion chamber 12 formed in the inner cavity of the carbonization tank A filled with rice husks and surrounded by the rice husks. Therefore, for example, if a guide vibro 2 is fixedly provided for starting, the guide vibro 2 may obstruct the flow of rice husks and carbonized rice husks,
In addition, the formation of the combustion chamber 12 becomes incomplete and the intended operation does not occur. However, in the present invention, as described above, the guide vibro 2 is attached to the fixed vibro 1. Since the guide vibro 2 is provided so that it can be inserted and removed freely, and the guide vibro 2 is pulled out after starting, it is easy to start, and it does not interfere with the combustion and carbonization operations.
