Abstract

PURPOSE:To enable to apply moisture and hot air in every nook and corner by a structure wherein fermentative substance such as feces of the silkworm or the like is stored in an enclosed container and humid air is blown downward from an air pipe, which is arranged at the top board part of the container in order to pressure-feed the humid air. CONSTITUTION:The fermentative substance 22 is housed in the upper chamber 5 of the enclosed container 1 and the humid air 23 is dischrged from above out of the opening of the air pipe 7 so as to fermment the fermentative substanc by giving moisture in order to generate the heat, by means of which the fermentation of the fermentative substance is more accelerated. Consequently, the heated air is flowed through the vent holes of a plate 4 into a lower chamber 6 and raised its temperature up to the predetermined temprature and, after that, sent by means of a blower 15 to a circulating pipe 10 so as to heat a silkworm breeding part by radiating the heat while circulating through the pipe 10 and then returned to the chamber 6 in order to be mixed again with the air heated by the fermentation heat during passing through the chamber 5 and, being drained the condensed water at a drainage part 20, to be circulated. Because the humid air is blown downward against the upper part of the fermentative substance, moisture and hot air are applied in every nook and corner and furthermore energy-saving is established by circulating said heated air.

Description

[Detailed Description of the Invention] This invention was made mainly for the purpose of saving energy when rearing silkworms in a rearing system. By pumping humidified air into this tank, fermentation of fermentable substances is promoted, and the heat generated at this time heats the humidified air.
The present invention relates to a heating device using fermentation heat, characterized in that the air is drawn out from a closed tank through a pipe body, circulated under the floor of a rearing silkworm bed, and heated by heat radiation.

Traditionally, when raising silkworms in a breeding facility, the breeding facility is installed in a facility such as a steel frame house or a plastic greenhouse as a means of keeping the breeding facility at an appropriate temperature, and the room temperature is raised by heating the entire room. things were being done. However,
Even if the overall temperature of the facility is raised, the rearing silkworm locus is located quite close to the ground, so the temperature may not be maintained at a comfortable temperature for the silkworms, which is lower than room temperature. In order to raise the temperature around the area, the facility had to be maintained at a fairly high temperature, which required a large amount of fuel and was extremely expensive.

Therefore, we focused on the fact that heat is generated when the feces of reared silkworms ferment, and created this invented device that uses the heat generated by fermentation to create a comfortable environment for rearing silkworms. .

Next, an example of implementation of the device of the present invention will be described with reference to the drawings.

A plate body 4 having a structure of 1 is horizontally suspended, and the interior with a sealing rate of 1 is divided into two upper and lower chambers 6, 6 by this plate body 4. 7 is an air pipe for supplying compressed air to the interior with a sealing rate of 1;
One end is connected to the compressor 8, the other end is connected to the center of the top plate part 9 with a sealing rate of 1, and a humidifier is installed in the middle of the air pipe 7 or at an appropriate position to supply humidified air within the sealing rate of 1. I am able to send it to you. Reference numeral 10 denotes a circulation pipe whose both ends are connected to the side wall portion 11 near the bottom plate 2 with the sealing rate of 1 and communicated with the lower chamber e in the sealing rate of 1. In the example, the U-shape is formed under the floor 13 of the rearing silkworm bed by bending the U-shape continuously, and this is supported by the support plate 14. Reference numeral 16 denotes a blower that sucks the air that has flowed into the lower chamber 6 in the sealing ratio 1, sends it under pressure into the circulation pipe 1o, and then returns the air to the lower chamber 6 through the circulation pipe 1o. It is used to circulate air, such as returning it to the air. The rearing device 12, that is, the rearing bed for silkworms, has a floor 13 made of wire mesh, a box-shaped silkworm rearing section surrounded by the floor 13 and four side plates 16, and a box-shaped silkworm rearing section 17 covered with an aluminum sheet 18 and an opening. is covered with a lid plate 19 to increase the heat retention of the silkworm rearing section 17. Reference numeral 2o denotes a water drain section provided in the pipe line of the circulation pipe 1o, which stores moisture generated when moist air circulates inside the circulation pipe 1o, and allows it to be discharged to the outside as appropriate. Reference numeral 21 is an exhaust port provided in the side wall portion 11 with a sealing rate of 1 to communicate with the lower chamber 6, and is used to release gas or heat within the sealing rate of 1 to the outside to maintain the sealing rate of 1. belongs to.

Next, the operation of the device of the present invention will be explained.

First, a fermentable substance 22 such as reared silkworms or livestock, especially cow dung, is stored in the chamber 6 above the sealing ratio 1, and after the sheep, air humidified by means not shown is sent by the compressor 8. It is pumped through the trachea 7 into the airtight area with a seal rate of 1. The humidified air 23 discharged from the opening of the air pipe 7 contains the stored fermentable substances 22
Fermentable substances flow into the space from above, ferment using moisture as a medium, and generate heat. The fermentation of the fermentable substances is further promoted by the heat generated by this fermentation and the moisture supplied, and the lower chamber 5 is set to about 2.5 rrf, in which cow dung and silkworm residue are added at a ratio of 7=3. Mixed; 1200kliJ
Experimental results showed that the internal temperature at a sealing rate of 1 rose to about 75°C to 80°C in about one week.

At this time, since high-temperature hot air rises due to heat convection in the airtightness ratio 1, humidified air 23 must be added in order to add moisture to this hot air and distribute it throughout the fermentable material amount again. It is desirable to force-feed from above the sealing rate of 1 to below.

Air pressed from above and heated by heat generated by fermentation flows into the lower chamber 6 with a sealing rate of 1 through the ventilation hole 3 of the plate 4. An experimental value was obtained in which the air flowing into the lower chamber 6 had a temperature of about 60° C. under the above conditions.

The air flowing into the lower chamber 6 with a sealing rate of 1 has a predetermined temperature,
In this embodiment, when the temperature reaches 60° C., the blower 16 provided in the circulation path is activated to forcefully send the heated air in the chamber e into the circulation pipe 10. As the air circulates through the circulation pipe 1o, it releases heat, and this heat radiation keeps the silkworm rearing section 17 of the rearing silkworm locus in this embodiment at a temperature of 22°C to 25°C. The air that circulated inside the circulation pipe 10 returns to the lower chamber 6 with a sealing rate of 1, receives heat in the upper chamber in this chamber 6, mixes with the air that has flowed down, and is returned to the circulation pipe by the blower 16. 1°, and this air circulation is repeated. The air that radiates heat within the circulation pipe 1° is also tinged with moisture, and as this air circulates, moisture accumulates within the circulation pipe 1o. This water is stored in a drainage part 2° provided in the pipe and is discharged to the outside as appropriate. Further, moisture accumulated within the sealing ratio 1 is appropriately discharged from a drain port (not shown) or the like.

Furthermore, if the pressure, temperature, etc. within the sealing ratio 1 rises abnormally, such as when air is not circulated into the circulation pipe 10, the exhaust port 21 is opened to release the air and reduce the pressure, temperature, etc. Lower it and stay safe.

As mentioned above, the device of the present invention has a sealing rate for storing fermentable substances such as silkworm dung, silkworm dung, or cow dung, and this sealing rate includes an air pipe for pressurizing humidified air to the top plate. Since it is attached, it is possible to blow humidified air from above to below onto the fermentable materials stored in the refrigerator, providing moisture and hot air to the fermentable materials in the refrigerator, promoting fermentation smoothly. , the generated heat can be efficiently increased.

In addition, a circulation pipe equipped with a blower is connected to the closed storage to guide the air that has received heat inside the storage to the outside of the storage. Since the incubator is configured to circulate, the incubator can be kept warm by the heat radiated from the circulation tube, and can be used not only for raising animals such as insects such as silkworms and chicks, but also for horticultural purposes such as growing flowers. Moreover, since the inside of the incubator is heated by heat radiation rather than being heated by blowing hot air into the incubator, the air inside the incubator is not contaminated. Furthermore, since the fuel uses the excrement of silkworms, etc., it has various useful effects, such as significantly reducing fuel costs and contributing greatly to energy conservation.
