Description

Multi-storeyed vermicomposting system

The present invention relates to a multi-layered earthworm breeding system capable of stacking earthworms in an automatic system.

Earthworms live in the ground and eat organic matters while they are living. Earthworms are used as medicines, cosmetic raw materials, and fishing baits. Feces (earthworm dung) are used as organic fertilizers, deodorants, and microbial carriers. Due to the above characteristics of earthworms, in recent years, attempts have been actively made to stabilize organic wastes such as food waste, sewage sludge, and livestock manure by using earthworms and recycle the by-products.

However, in our country, firstly, the land cost for securing earthworm breeding site is excessive, and secondly, the temperature change according to season is so severe that the summer high temperature and winter low temperature are not suitable for the earthworm growth environment, and the third series for earthworm breeding. The fact that their work is to deal with waste, the fact that they are a typical repellent industry, is an obstacle to the mass production of earthworms and the development of environmental treatment technology using earthworms.

In order to solve the problem of the earthworm breeding, it is necessary to maximize the land use efficiency by multiplying and three-dimensional the earthworm breeding space, and to control the breeding environment such as temperature, light and moisture throughout the year, and to feed the earthworm food and to separate the excess feces. By doing this automatically, the pain of evasion should be eliminated.

When the breeding bed is a bed type in the conventional three-dimensional multi-layered earthworm breeding system, the earthworm breeding bed is a conveyor belt type, so that the feces at the edge of the breeding land is dropped to the bottom by rotating the conveyor belt at regular intervals. Patent application No. 1999-42952, which results in the removal of the earthworm eggs scattered in the fecal soil, there is a problem that the life history of the earthworm population in the breeding can not be stably continued.

In addition, in the existing box-type multi-layer breeding device, a mesh size of 2 cm is laid at the bottom of the box, and the stool is excavated with stool along with the stool, and the stool is lowered by the gravity of the lower stool. (Patent Application No. 1999-28588) However, when the water content of fecal soil increases or becomes more viscous, wire mesh and fecal soil at the bottom of the breeding are in close contact, and natural fall by gravity is difficult and during earthworm breeding Once the path of the wire mesh is blocked, fecal soil separation is no longer possible.

The multi-layered earthworm breeding system has already proven to fail due to the above problems.

The present inventors have devised an earthworm breeding box that can separate the excess fecal soil on the earthworm breeding ground, that is, on the multilayered breeding system, which is a prerequisite for the development of the multilayered earthworm automatic breeding system. (Patent application 2001-63938)

Therefore, an object of the present invention is to use the "earthworm breeding box for separation of excess fecal soil" proposed by the present inventor in order to efficiently recycle various organic wastes including food waste, the earthworms can be stacked in a box and reared by an automatic system. To provide an automated three-dimensional, multi-layered earthworm breeding system.

The earthworm breeding system of the present invention has a food waste pretreatment unit and supplies feed obtained from the food waste pretreatment unit, and loads and unloads the earthworm breeding box, and removes the fecal soil of a plurality of earthworm breeding boxes and a earthworm breeding box. It consists of a box loader and a rail on which the box loader is placed and stored.

The earthworm breeding system of the present invention is described in detail with reference to the embodiment shown in the accompanying drawings.

Figure 1 shows the configuration of the earthworm breeding system of the present invention, a food waste pre-treatment unit 1 and a plurality of earthworm breeding box (2) for loading and unloading the operating unit 3 and the earthworm breeding box (2) The box loader 5 and the box loader 5 in which the box is stored are constituted by rails 6 moved thereon.

Food waste pretreatment unit is composed of food processing unit and fermentation tank.

In the present invention, the food waste pretreatment unit 1 is installed by using food waste as food waste, but when using other feed, it can be replaced by a corresponding facility.

2 shows a configuration of the food waste pretreatment unit of the present invention as a front view. The food waste treatment unit has a food input screw conveyor 10, a crusher 11, a dehydrator 12, and a discharge conveyor 13 arranged in a line.

Each of these components is conventional and will not be described in detail.

The outlet of the discharge conveyor 13 is located above the fermenter 7 shown in FIG.

Referring back to FIG. 2, the fermenter 7 is provided with a trolley 14, and the trolley 14 is provided with a screw 15 for stirring food waste.

The fermentation tank bogie 14 moves the fermented food waste near the operating part 3 while moving the fermentation tank 7 shown in FIG. 1 over the entire section.

The operation part 3 includes a roller conveyor 30 movable from side to side and a feed hopper 31 and a fecal soil on one side of the roller conveyor. It is composed of a loading arm 33 for loading the breeding box 2 and the unloading arm 34 for unloading the breeding box with the removal part 32 facing the other side.

The roller conveyor 30 is movable on the rail 4.

In front of the loading arm 33 and the unloading arm 34, the box loaders 5 are arranged in a row, and the box loaders shown in FIG. 3 are arranged in two rows. If necessary, the box loader can be extended and arranged in two or more rows and several tens of rows.

The operation of the operating portion of the present invention will be described.

First, the feed is provided to the feed hopper 31 and the feed hopper is provided with four feed outlets 35 for feeding the feed. Each feed outlet 35 has a different length of the outlet so that the feed is evenly discharged.

The roller conveyor 30 is arrange | positioned so that the loading arm 33 and the unloading arm 34 may be located in the box loader 5 of the left side and the center.

First, the loading arm 33 picks up the breeding box 2 of the box loader 5 and places it on the roller conveyor 30.

Next, the breeding box 2 is moved on the roller conveyor 30 so as to be located in front of the feed hopper 30. At this time, feed is supplied from the feed outlet 35 of the feed hopper 30.

The breeding box 2 moves again to be located in front of the fecal soil removing unit 32 and the fecal soil removing unit 32 discharges the fecal soil accumulated in the lower portion of the breeding box 2 by the operation of the cylinder 36.

Fecal soil removal works only when fecal soil removal is necessary.

The breeding box 2 has the same configuration as the earthworm breeding box described in Patent Application No. 2001-63938, which does not mention the detailed configuration of the breeding box.

The breeding box 2 from which the feces are removed is moved from the roller conveyor 30 to the box loader 5 located in the middle row by the unloading arm 34.

All the earthworm breeding boxes stored in the box loader 5 are moved in the repetition of the above operation.

The box loaders 5 are connected in line and move on the rails 6.

The loading arm and the unloading arm of the actuating part of the present invention can reverse the function as necessary. In other words, when the roller conveyor of the actuating section is operated in the box loaders in the middle row and the right row, the loading arm acts as the unloading arm and the unloading arm acts as the loading arm to pick up the breeding box.

The multi-layered earthworm breeding system of the present invention configured as described above enables mass production in a narrow space by a method of stacking box breeding and is intensively managed to facilitate the control of the earthworm breeding environment to enable uniform production throughout the year and to flow the entire process. Automation allows the production of earthworms uniformly, providing the ability to treat certain organic wastes and to supply the earthworm production as an industrial raw material. In addition, it is effective to provide an earthworm breeding system that provides economic efficiency by greatly reducing the administration labor by treating such a production process with a factory automatic treatment concept.

As a result, the above-described breeding system has a multi-layered and three-dimensional earthworm breeding box, so that the maximum processing area can be secured in a minimum space, and the temperature, humidity, and light conditions required for growing the earthworm can be adjusted at a minimum cost.
