BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing a smoked condensate (wood vinegar solution) having an antibacterial or bactericidal effect against various bacteria which adversely affect agricultural products.

[0002]

2. Description of the Prior Art
Japanese Patent No. 61 discloses a device that mass-produces a condensed component and a water-extracted component from smoke generated when incompletely burning a wood-based material. This is the same in appearance as the device shown in FIG. 7, and rotatably supports a liquid container 21 on a base frame 22, and the liquid container 21 is placed at the center of rotation of this container 21.
Is rotatably supported by a rotation drive means, and a smoke inflow port 32 and a smoke outflow port 30 are provided in this container, smoke is passed through the liquid container, and the smoke component is efficiently transferred to the water in the container. It is a device.

Further, as a source of smoke, conventionally, smoke exhaust from a charcoal-burning kiln has been used. However, since the main purpose is to use the smoke produced as a by-product during charcoal-burning, smoke-condensing The smoke producing device for producing the liquid has drawbacks such as limited use place, inability to control the amount of produced smoke, and immediate production of smoke as necessary. From such a point, as typical ones of grass and wood powder,
We considered the use of smoky smoke using husks as fuel, but in the conventional charcoal burning equipment of husks, a chimney was set up in the burning part of the husks, and this burning part was covered with the husks, so that air was taken in by the intake force of the chimneys. Since it is a method of continuously burning and carbonizing while the combustion part gradually moves upward by reaching the combustion part through the chaff and passing through the chimney, it takes a certain time to continuously generate smoke. Each time, it was necessary to move and replenish the chaff, which was troublesome.

On the other hand, rice husks are produced in large quantities at the rice milling place, but if they are transported to the place where the smoke producing device is installed, transportation costs will increase and the price of the smoke condensate will become expensive. Therefore, the smoke generating device and the smoke condensing device can be moved to and installed at the place where smoky husks are generated, and the processing capacity can be adjusted depending on the amount of smoky husks and the required amount of smoke smoke condensate. A device that can do this is desired.

[0005]

In the apparatus described above, the cap 28 is removed in FIG. 7 and water is injected from the inlet. Although the injection amount varies depending on the rotation speed of the container, etc., the water level in the container rises as the condensation of smoke components progresses, so during the rotation of the container 1, it is far from the position where water overflows from the smoke inlet, etc. Can be less. When water is added, the cap 28 is tightened to drive the motor 27 and the blower 52. On the other hand, in the smoke generating device, dumplings, shovel cars, or conveyor devices are used to throw the chaff into the chaff combustion chamber N to fill the chaff. Ignition device F consisting of oil burner
Is operated to introduce high temperature combustion exhaust gas into the flue chamber S. At this time, the on-off valve V is set in the open state. Rice husk is heated through the perforated plates 7 and 8 and ignites, and begins to emit smoke. When the time set in advance in the ignition device has passed, the ignition device extinguishes the fire and at the same time, the on-off valve V closes.

When the combustion layer of the chaffing combustion chamber moves upwards after a preset time has passed since the ignition device disappeared, the motor M for driving the screw conveyor K
Begins to rotate slowly and the belt conveyor 1
7 is driven, and smoky charcoal that has generated smoke and carbonized is conveyed by the screw conveyor K toward the dropping port. On the way, the smoldering charcoal that has sufficiently absorbed water in the sprinkling fire extinguisher chamber 9 is caused by the screw conveyor K causing the screw blades to be missing in the conveying path from the sprinkling fire extinguisher chamber 9 to the drop port, thereby lowering the conveying ability. , In the transport path from the sprinkling fire extinguisher chamber to the drop port, the transport path is blocked by filling it, reaches the drop port in a state of being pushed out by the subsequent smoky charcoal, and is dropped and supplied onto the belt conveyor.
Instead of removing the screw blades, the transport path in this part is made cylindrical with a small gap according to the diameter of the screw blades, and even if the transport path is lengthened and lengthened, It has the same air blocking effect of.

In a normal state, the smoky charcoal is guided by the perforated plate and supplied to the screw conveyor K. However, a tunnel-shaped cavity is formed in the chaffed coal layer to convey the chamomile smoky charcoal and to continuously burn the chaff. However, there is a risk of breaks.
In order to avoid such a situation, as shown by the alternate long and short dash line in FIG.
A stirring shaft 100 parallel to the screw shaft 5 and a stirring rod 101 projecting at a right angle to the shaft, and a sprocket 103 provided at one end of the stirring shaft 100 is attached to a sprocket at the end of the screw shaft to a chain 104. Since the upper part of the rice husk layer is continuously agitated by the agitating rod 101, the cavity is not formed on the screw conveyor. This may be provided as a vibrating body that converts the rotation of the sprocket at the end of the screw shaft into a reciprocating motion in the vertical direction and moves up and down in the chaff layer.

The suction force by the ejector pipe 51 is exerted from the smoke conduit to the flue chamber, and the combustion air is supplied from the upper part of the chaffing layer to the combustion part in the chaffing layer below the chaffing layer. The smoke enters the air separation chamber 43 of the liquid container 21 from the flue chamber through the smoke conduit. The smoke passes from the ventilation plate 42 through the plurality of smoke flow paths 46 and 47, and enters the air collection chamber 4
Go out from the smoke exhaust port 30 via 4. The container 21 rotates on the roller at a speed of about 2 to 10 times per minute in accordance with the rotation of the supporting roller 25b for driving, and accordingly, the container 2
The water in 1 is drawn up from the numerous holes of the partition plate 45 while being pumped upward by the partition plate 45, so that the water is scattered and sufficiently comes into contact with the smoke passing through the container. Is cooled and condensed, and the water-soluble components are dissolved and extracted. Similarly, the filling bodies 48, ... Are also rolled by the partition plate 45 to enhance the contact efficiency with the smoke and capture the smoke components on the surface thereof.

Further, since the partition plate 45 encloses the filling bodies 48, ... In the plurality of smoke flow paths of the container 21, the filling body is surely kept in the lower half of the container as the liquid container rotates. While passing through the water layer in the part and transferring the smoke condensate component adhering to the surface to the water layer, it is cooled by water itself.
The heat radiating plates 34, ... Are provided so as to project from the outer peripheral surface of the container 21, thereby disturbing the air on the surface and generating a turbulent flow, thereby enhancing the air cooling effect and increasing the water temperature in the container. To prevent the vaporization of condensed components and the alteration of extracted components. In this way, after operating for a certain period of time, the valve 29 is opened and the smoke condensate is taken out.

In the first embodiment, the liquid container is the container 21.
By the support roller that supports from the left and right centering on the center of gravity of
It is rotatably supported via ring-shaped rails 23, 23 provided around the outer peripheral surface of the container. This is, for example, as shown in FIG. 11, a short tubular portion forming a smoke inlet 142 and a smoke outlet 140. May be rotatably supported on the base frame by the bearing members 141 and 241. As the driving means at that time, for example, a publicly known driving means such as a driven pulley 143 provided integrally with the smoke exhaust port 140 so as to be able to rotate integrally with the output pulley 144 of the motor 146 to rotate via a belt 145 can be adopted. . Further, the shape of the liquid container does not need to be a rotating body like a cylindrical drum. 131 is an ejector tube, 132 is a blower, and 116 is a chimney tube.

The smoke exhaust port may be opened to the atmosphere through a chimney having a strong suction force without attaching the suction device as in the embodiment.
Further, when automating the extraction of the smoke condensate and the injection of water as the cooling extract into the container 21, for example, in FIG. 10, one end of the water supply pipe 80 is connected to the smoke inlet 32.
In addition to opening through the smoke conduit 16, a water supply electromagnetic valve 81 and a flow meter (not shown) are provided in the water supply pipe 80, and the take-out valve 82 and the overflow valve 83 also serve as electromagnetic valves to prevent the smoke condensate from flowing. When taking out, only the take-out valve may be opened and closed, and when pouring water, the overflow valve 83 and the water supply valve 81 may be opened to control both valves when the flow meter detects a predetermined amount of water. The valve 83 may be omitted.

In the smoke smoke condensate producing apparatus of the first embodiment, the side wall 1b on one side of the box 1 of the smoke generating apparatus can be approached by a chaffed mine transport vehicle such as a dump truck, and the side wall 1c opposite to the side wall 1b. A screw conduit K and a smoke condensing device G are provided so as to project on the side, and side walls 1d and 1e on both sides sandwiching the both side walls sandwich another side wall of the smoke generating device. There is no problem even if they are arranged side by side, and therefore, the smoke generating devices can be arranged in rows on both sides of the side walls 1d and 1e according to the amount of smoke required. The required number of condensers G corresponding to the amount of smoke generated can be provided in these smoke generators.
In this way, by unitizing the smoke generating device and the smoke condensing device, the capacity of the device can be adjusted freely. The device is easy to disassemble, and it does not take up much space for transportation, installation, and storage when not in use. Below the perforated plates 7 and 8,
Since the perforated plates need to be cleaned, the perforated plates may be simply fastened.

It may be rounded so as to satisfy 0. Reference numeral 363 is a conducting wire connected to the nichrome wire heater 361, which is heat-resistant and insulation-coated, and is connected to a power source through an open / close switch. It is desirable that the outside of the flue chamber 350 is first covered with a layer 358 in which a fuel oil such as kerosene or heavy oil is impregnated with fluffy or fluffy charcoal to a thickness of about 3 to 5 cm. Then, the chaff 359 is piled up on the outside so that the flue chamber 350 is completely buried in the chaff.

[0037]

When a push button switch (not shown) is turned on, the nichrome wire heater 331 is energized to ignite the newspaper. At this time, since air is supplied from the air introduction port 351d, the fire is burned by the oil-containing fluffy charcoal bed 358.
The temperature of the combustion air in the smoke conduit rises rapidly. The temperature around the base of the smoke pipe made of iron plate is about 8
If the temperature is higher than 0 ° C, continuous burning of the chaffed mud layer 359 will be ensured.
A temperature sensor (not shown) detects this state, operates the solenoid 78, and closes the on-off valve V. When the on-off valve is closed, air is supplied to the combusting portion little by little through the chaffed moth layer, so that the burned chaff continues to burn in a steamed state while the burned portion gradually moves to the unburned portion.
The smoke produced is supplied to the smoke condensing device through the air chamber from the smoke conduit 316. The combustion duration is adjusted by the amount of chaff. This device is inexpensive and suitable for batch processing of rice husks, but continuous processing is also possible.

[Effect] The smoke generating device of the present application is easy to unitize, does not occupy an installation space, and depending on the generation status of powder and granules such as chaff and waste sawdust, for example, a large amount of chaff is continuously generated. When it occurs or when it is concentrated at one time such as at the time of harvesting, it is possible to efficiently generate smoke with a small equipment cost and to manufacture smoldering charcoal of granular material according to each case. . Smoked charcoal in the form of granules is extremely effective as a soil improving material, an adsorbent, a water quality improving agent, and can be used as a fuel. Therefore, the smoke generating device of the present application is, on the one hand, an excellent rice husk smoldering device, and in the device of the present application, both of them are generated at the same time. It should be understood to mean meaning. In particular, the waste culture medium after being used for mushroom cultivation contains a large amount of water, and it was difficult to burn it by a normal burning method. it can.
