Description

  The present invention relates to an organic waste treatment apparatus such as garbage and thinned wood, and more particularly to an easy-to-use organic waste treatment apparatus using steam.

  There are methods of landfilling and incineration to dispose of garbage. Some of them use microorganisms to make fertilizer. Thinned wood is also processed into chips and incinerated.

  In order to reclaim garbage, a large space is required, and there is a risk that malodours and rats will breed. Incineration of food waste requires a lot of heavy oil because it contains a large amount of water. In addition, incineration of thinned wood generates carbon dioxide, which causes global warming.

Although some methods have been used to decompose raw garbage with microorganisms into fertilizers, they are still in the experimental stage and have not yet been able to efficiently treat large amounts of raw garbage. Therefore, an apparatus that treats garbage with steam is drawing attention. Patent Document 1 discloses a processing apparatus that uses high-temperature and high-pressure steam at 230 ° C. and 3 MPa to thermally decompose organic waste. However, it was not easy to use (especially agitation performance) that is small and does not occupy a wide space and does not use a large amount of heavy oil.

  An object of the present invention is to provide an organic waste disposal apparatus that uses steam and is easy to use.

  In order to achieve the above object, the organic waste processing apparatus according to the present invention is provided with an organic waste carry-in port and a treated organic waste discharge port, and is a spherical shape that is sealed and rotated. The steam cooker, a through-shaft that passes through and supports the inside of the steam cooker, is rotated at a speed different from that of the steam cooker, a plurality of paddles attached to the through-shaft, and the through-shaft A steam inlet provided at one end, to which steam having a temperature of 150 to 210 ° C. and a pressure of 15 to 21 atm is supplied. The steam kettle is charged with organic waste, and the steam is sealed. The steam pot and the paddle are rotated and stirred for a predetermined time in a state where steam is supplied from the inlet.

  A transport pipe is provided between the carry-in port and the organic waste collection container, and the organic waste is sucked by a vacuum pump and put into the steam kettle.

  According to the first aspect of the present invention, (a) since the steam kettle is rotated, the stirring performance can be remarkably improved. Further, the plurality of paddles inside the steam pot scoop up the organic waste accumulated at the bottom like a shovel while rotating, so that the stirring ability is superior to that of a rod-shaped stirring tool. Furthermore, since the speed at which the steam pot is rotated and the speed at which the paddle is rotated are different, stirring can be effectively promoted. (B) Since the steam of the boiler having a temperature of 150 to 210 ° C. and a pressure of 15 to 21 is fed as it is in a state where the steam pot is sealed, the steam does not escape and an energy saving apparatus can be obtained. At this temperature, the organic waste is not carbonized, and the powder obtained after the treatment can be used by being mixed with livestock feed. It can also be used as a fertilizer. (C) Since the steam kettle has a spherical shape, organic waste in powder form is collected by its own weight at the lower discharge port, so that it is not clogged. Further, if the paddle is rotated at the time of discharge, the powder can be discharged without leaving the powder inside the steam pot from the discharge port.

  According to the second aspect, since the organic waste is sucked by the vacuum pump and put into the steam kettle, the odor is not diffused around the belt conveyor and the apparatus is downsized. it can.

  Hereinafter, an organic waste processing apparatus according to the present invention will be described with reference to the drawings.

  FIG. 1 shows an organic waste processing apparatus (Example 1) according to the present invention. A spherical steam kettle 1 is installed in the approximate center of FIG. A garbage carry-in port 11 is provided on the upper side of the steam pot 1 and a discharge port 4 for taking out the treated waste is provided on the lower side. The steam cooker 1 is supported by left and right bearings 7 and 12. The steam pot 1 is configured to be rotatable, and a motor 2 for rotating the steam pot 1 is provided on the right side of the bearing 12. This steam kettle 1 can process organic waste by high temperature and pressurized steam. A steam inlet 8 for receiving steam from the boiler is provided on the left side of the bearing 7.

  A penetrating shaft 15 is provided inside the steam pot 1. A plurality of paddles 16 are attached to the through shaft 15. The motor 3 that rotates the through shaft 15 is provided at the lower right of the steam pot 1. The plurality of paddles 16 are attached to the penetrating shaft 15 so as to be alternately arranged vertically.

  FIG. 2 shows an organic waste processing apparatus according to the present invention (Example 2). After the garbage is collected in the collection container 10, it is drawn by the vacuum pump 13, passes through the transfer pipe 14, and is carried to the carry-in port 11 of the steam pot 1. Other configurations are the same.

  The operation of the organic waste processing apparatus according to the present invention will be described. First, garbage or pruned branches are first transferred to the collection container 10. The garbage may be subjected to a pretreatment for dehydration and pulverization before being transferred to the collection container 10. According to the first embodiment, the garbage in the collection container 10 is carried on the belt conveyor 9 with a basket driven by the rotation of the motor 5 and carried to the carry-in port 11 of the steam pot 1. According to the second embodiment, the garbage in the collection container 10 is sucked by the vacuum pump 13 and is transported to the carry-in port 11 of the steam kettle 1 through the transport pipe 14. The carry-in port 11 of the steam pot 11 is opened by driving the motor 6, and the garbage is put into the steam pot 1. After completion of carrying in the garbage, the carry-in port 11 of the steam pot 1 is closed. The lid is a detachable clutch type, and a plurality of motors 6 slide, move up and down, and detach (lock) the lid in the left-right direction. Both the lid of the carry-in port 11 of the steam pot 1 and the lid of the discharge port 4 are opened and closed by positioning the lid at a place where this mechanism exists.

  When the carry-in port 11 and the discharge port 4 are closed, the steam kettle 1 becomes a sealed container. Here, the steam pressurized at high temperature is fed from the steam inlet 8 into the steam pot 1. The vapor pressure is 15 to 21 atmospheres, and the temperature at this time is 150 to 210 ° C. Next, the steam pot 1 is rotated by the motor 2. At the same time, the through shaft 15 is rotated by the motor 3. As a result, the plurality of paddles 16 in the steam pot 1 also rotate. In order to increase the degree of stirring, the rotational speed of the paddle 16 was made faster than the rotational speed of the steam pot 1. As an example, the rotation speed of the steam pot 1 was 2 rpm, and the rotation speed of the paddle 16 was 3.5 rpm. In addition, the rotation can be forward and reverse.

  When operated in this manner, the garbage is thermally decomposed and stirred in a high-temperature, pressurized atmosphere. Even if you cook brown rice in a normal pot, you can hardly cook it, but you can cook it in a pressure cooker. This is because the pressure cooker is hot and high in pressure, making it easier for heat to be transferred to the inside of the brown rice. A similar phenomenon occurs in the steam cooker 1. Since the garbage contains moisture, the garbage is hydrolyzed. Of the substances that constitute garbage, those that volatilize at 150 ° C. or below are steamed to become gases. In the vicinity of 150 ° C., most plant fibers become brittle, and when the stirring force by the steam pot 1 and the paddle 16 is applied, they are crushed and become fine. If operation is continued for 40 to 50 minutes, garbage, pruned branches, etc. become powdery.

  After completion of the operation, the steam pot 1 is naturally cooled and the powder is taken out from the discharge port 4. In addition, if this is dried, it can be used as a fertilizer or livestock feed. When the thinned wood chips are processed in the steam pot 1, the vinegar (mokaku) liquid accumulates in the discharge port 4. This is valuable as an insecticide. After completion of the operation, the steam in the steam kettle 1 may be collected in a steam collecting machine provided separately to separate the active components contained in the steam.

  It seems that a large amount of energy is required to create a high-temperature and pressurized atmosphere, but the steam pot 1 is sealed and can be produced with much less energy than burning garbage containing moisture. Garbage can be processed. Also, the problem of odor is that until the garbage is brought in, no odor is produced during and after the treatment.

  The present invention is suitable for an organic waste treatment apparatus that is small in size and has a small installation area.

It is a block diagram of the organic waste processing apparatus according to the present invention. Example 1 It is a block diagram of the organic waste processing apparatus according to the present invention. (Example 2)
