[0001]

[Industrial applications]

 The present invention relates to a technology for treating raw dust, which is a household waste, and relates to an apparatus for producing mulch soil using the raw dust.

[0002]

[Prior art]

 In recent years, the problem of reducing the amount of living dust has been highlighted along with the problem of the global environment, and in particular, the treatment and disposal of raw dust, which is a household waste, has many difficult problems.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above problems, and in particular, it is intended for the purpose of returning to the earth the domestic raw dust emitted from individual kitchens every day. It is an object of the present invention to provide a small-sized and easy-to-handle device for producing a mulberry soil-based mulch for returning to soil as organic fertilizer.

[0004]

[Means for Solving the Problems]

 The apparatus for producing mulch soil from raw dust according to the present invention is provided with a barrel-shaped container body having a barrel-shaped container having an opening / closing lid at one end and an opening / closing lid. A rolling roller to be mounted on a bearing is axially arranged, and at least one of the rolling rollers is composed of a base part for controlling forward / reverse rotation at an appropriate speed by a motor, and is placed at the axial center of the container body. A cylindrical conical cone is projected from the other end of the container body in the direction of the inner cavity, and the ambient temperature of the inner cavity of the container exceeds the preset temperature by the temperature detection means at the outer end or inside the conical cone. In addition to configuring an automatic ventilation control window that opens when opened, a stirring structure consisting of fins or protrusions is configured on the inner circumference of the peripheral wall of the container body described above, and the container is placed on the rolling rollers of the above base. Equipped with a main body, the dust and soil stored in the lumen from the input / output port can be moved at a very low speed. While it is rolling, and the temperature of the natural heat generated by the decomposition of the raw dust by microorganisms of the soil and kept constant through the automatic vent control window, it is an gist over time to produce humus.

Further, the temperature detecting means of the automatic ventilation control window can be implemented by a shape memory alloy, and a closing coil spring made of spring steel having a relatively small elastic coefficient is used to open and close the opening and closing window elastically biased toward the closing side. The gist is that the structure is such that a closing coil spring made of a shape memory alloy having a larger elastic coefficient than the closing coil spring temperature-stored at a set temperature is elastically biased toward the open side.

The agitating structure of the container body is composed of one or a plurality of screw fins continuous in the front-rear direction of the container, and the motor of the base is rotated forward or backward to agitate the contents of the container body. Or it is desirable to discharge. Furthermore, it is preferable that the container body has a double-walled heat insulating structure.

[0007]

[Action]

 According to the above configuration, while rotating the motor of the base part in the forward direction to rotate the container body placed on the rolling roller at a very low speed, raw dust is thrown into the inner cavity from the charging / discharging port, Place approximately equal weight of soil in a volume equivalent to approximately 1/3 or less of the container volume and leave it for 3 to 7 days with the lid closed.

At the initial stage of the introduction of raw dust, the temperature of the atmosphere inside the container body is substantially equal to the temperature of the outside air, so the temperature detecting means operates in the direction to close the automatic ventilation control window to block the ventilation with the outside air. ing. However, this block is not sealed and does not affect the survival of microorganisms in the soil. If left in this state, the microorganisms in the soil will decompose the raw dust that was put in with it, and at the same time, the amount of oxygen in the soil will be maintained as it is agitated by the rolling of the container to maintain the amount of oxygen in the soil. The ambient temperature of the container lumen rises.

[0009] The increase in the ambient temperature activates the activity of microorganisms and accelerates the decomposition rate. However, when the temperature exceeds a certain temperature (living temperature of microorganisms), the activity of microorganisms is extremely hindered. The temperature detection means is set to the upper limit of the temperature atmosphere, and when the set temperature is detected, the automatic ventilation control window provided in the conical cone opens to greatly open the inner air to the outside air, and the temperature rises according to the outside air temperature. Acts to lower the cavity temperature atmosphere.

Further, if the temperature atmosphere in the inner cavity of the container body becomes too low due to the opening of the automatic ventilation control window, the activity of microorganisms in the soil becomes small. Therefore, if the temperature detecting means detects this lower limit, the automatic ventilation control window will be opened. It is closed and operates to block a large opening to the outside air. Due to this closing, the lumen temperature of the container body starts to rise again, and the decomposition activity of soil microorganisms is maintained at a good temperature state.

After standing for 3 to 7 days, raw dust is completely decomposed and stirred with soil to form mulch. Then, the motor of the base part is reversed to discharge the mulch generated from the input / exhaust port, and is mixed with the soil to be commonly used as an organic fertilizer.

[0012] When the stirring is continued for about one week after the mulch is formed, the mulch is completely dried and a storable organic soil-containing fertilizer can be obtained.

【Example】

 Hereinafter, an embodiment of the apparatus for producing mulch based on fresh dust according to the present invention will be described with reference to the drawings. Reference numeral 1 is a container body having a barrel-shaped container having a double structure with an inner wall 2 and an outer wall 3 and an opening / closing port 4 having an opening / closing lid 4 provided at one end to form a barrel-shaped container. , Is rotatably mounted on rolling rollers 7, 7, 7 and a driving roller 8 which are rotatably provided on the upper surface of the base 6.

The opening / closing lid 4 of the container body 1 is detachable by a clamp structure 9, and a handle 10 is provided on the outer surface so as to project. Reference numeral 11 is a cylindrical cylindrical cone located axially from the transparent window 13 opened in the bottom wall 12 of the container body 1 and protruding toward the inner cavity 14, the inner end of which is the above-mentioned charging / discharging port. It opens toward 5.

Further, both ends of the container body 1 constitute tapered walls 15 and 15 which are inclined so as to have a small diameter, respectively, and a single-screw fin having a relatively narrow width over the entire length of the inner wall. 16 is screwed to the right.

Reference numeral 22 is an automatic ventilation control window located in the transparent window 13 and formed in the cylinder of the conical cone 11. The rotary plate 24 is located at the fixed plate 23 and the axial center position of the fixed plate 23. A plurality of corresponding through holes 26 and 27 are formed in the rotary plate 25 that is rotatably provided through the rotary plate 25. The turntable 25 has a rotation stroke (arrow A) between the fixed plate 23 and the positions where the two through holes 26 and 27 overlap each other and the position where they do not overlap each other, and is relatively elastic in the non-overlapping direction. A closing coil spring 28 made of spring steel having a small coefficient is constantly elastically urged, and an opening coil spring 29 made of a shape memory alloy whose temperature is stored at a set temperature is located in the inner cavity 14 in a direction in which the closing coil spring 28 and the closing coil spring 28 are overlapped with each other. The elastically biased temperature detecting means 30 constitutes. The open coil spring 29 made of the shape memory alloy has an elastic coefficient sufficiently larger than that of the closing coil spring 28 and operates against the elasticity of the closing coil spring 28 during operation.

In the container body 1, guide rings 17, 17 are fitted on the outer periphery of the outer wall 3, and the guide rings 17, 17 are attached to the front rolling rollers 7, 7 and the rear rolling rollers 7 and the driving rollers. 8 is rotatably mounted on and slidably mounted on the base 8. The rolling rollers 7, 7, 7 and the driving roller 8 are axially mounted on a pivot shaft mounted on a base 18, and the driving roller 8 is mounted on the base. The container body 1 is drivingly connected to a motor 19 fixed to the table 18 through a speed reducer 20, and an operation input from an operation switch 21 causes the container body 1 to rotate slightly in the left direction (1 to 2 rotations / minute) and rotate in the right high speed (20 rotations / minute). ~ 30 rotations / minute).

Next, a process of forming mulch by the mulch-producing device using raw dust having the above-described structure will be described. (1) Raw dust such as vegetable scraps and leftovers of fish meat generated from the kitchen and approximately the same amount of soil as the raw dust are put into the inner cavity 14 through the input / output port 5 and the opening / closing lid 4 is attached to the clamp structure 9. Thus, the motor 19 of the base 6 is normally rotated in the closed state, and the container body 1 placed on the rolling roller 7 and the driving roller 8 is rotated at a slight speed (1 rotation / minute). The raw dust and soil are set to a volume equivalent to about 1/3 or less of the container volume (20 to 40 liters) and placed for 3 to 7 days with the opening / closing lid 4 closed. At this time, rice bran can be added to shorten the fermentation period, and superphosphate can be added to neutralize the acidic soil. Further, various deodorants including oxygen / bacterial agent deodorants such as proteolytic enzymes can be added. (2) Since the temperature of the atmosphere in the inner cavity of the container body 1 is not substantially equal to the temperature of the outside air at the initial stage of the introduction of dust, the temperature detecting means 30 has an open coil in which the elastic coefficient of the closing coil spring 28 is formed by a shape memory alloy. Since the elastic coefficient of the spring 29 is larger than that of the spring 29, the fixed plate 23 and the rotary plate 25 are displaced to positions where the through holes 26 and 27 do not overlap with each other, and the automatic ventilation control window 22 is actuated in a direction to close the ventilation with the outside air. It is shut off. However, this block is not sealed and does not affect the survival of microorganisms in the soil. If left in this state, the microorganisms in the soil will decompose the raw dust that was put in with it, and at the same time it will be agitated by the rolling of the container body 1 to maintain the amount of oxygen in the soil, which will cause decomposition and fermentation. The ambient temperature of the container lumen 14 rises due to the heat generation (heat). (3) The increase in the ambient temperature activates the activity of microorganisms and accelerates the decomposition rate. However, when the temperature exceeds a certain temperature (living temperature of microorganisms), the activity of microorganisms is extremely hindered. The temperature detecting means 30 is set to the upper limit of the temperature atmosphere, and when the set temperature is detected, the automatic ventilation control window 22 provided in the conical cone 11 has the elastic coefficient of the closing coil spring 28 made of a shape memory alloy. Since the elastic coefficient of the open coil spring 29 is smaller than the elastic coefficient of the open coil spring 29, the fixed plate 23 and the rotary plate 25 are displaced and opened to the position where the through holes 26 and 27 of the rotary plate 25 are overlapped with each other. Acts to lower the elevated lumen temperature atmosphere. (4) Further, if the temperature of the inner cavity of the container body 1 becomes too low due to the opening of the automatic ventilation control window 22, the activity of microorganisms in the soil will decrease. The ventilation control window 22 is closed and operates so as to block a large opening to the outside air. By this closing, the lumen temperature of the container body 1 starts to rise again, and the decomposition activity of soil microorganisms is maintained at a favorable temperature state. After standing for 3 to 7 days, raw dust is completely decomposed and stirred with soil to form mulch. (5) When the generated mulch is discharged, the motor 19 of the base 6 is reversely rotated at high speed (1 rotation / 1 second) with the clamp structure 9 removed and the opening / closing lid 4 removed. When the container main body 1 reverses the container main body 1 placed on the rolling roller 7 and the driving roller 8 at high speed, the spiral fin 16 is provided on the inner wall, and thus the generated leaf soil is automatically fed from the input / output port 5. Is discharged. This mulch is mixed with soil and used as organic fertilizer. (6) If the stirring is continued for about a week after the mulch is formed, the mulch is completely dried and becomes a storable organic soil-containing fertilizer.

In the above-mentioned embodiment, the stirring structure is composed of a single spiral fin, but the spiral fin may have multiple spiral fins, or the spiral fin may be projected on the inner wall 2 and arranged in a spiral shape. It may be a short rod-shaped projection group. Further, when the temperature effect from the wall surface of the container due to the outside air temperature is small, the container body 1 does not need to have a double structure.

In addition, although the exothermic structure utilizing the heat of decomposition and fermentation of raw dust has been shown in the above-mentioned embodiment, the structure in which the heater is built in the double structure of the container body 1 allows for forced heating. It goes without saying that you can do it.

[0021]

[Effect of device]

 As described above, according to the apparatus for producing mulch soil using raw dust according to the present invention, it is only necessary to put the raw dust discharged from the kitchen together with the soil into a cheerful position, and microbes such as spoilage bacteria in the soil. By this action, leaf soil, which is an organic fertilizer, will be generated after 2 to 7 days, and the temperature control inside the container is controlled by the temperature detection means made of shape memory alloy, and the structure is simple, In addition, it has features such as no need for heating. Furthermore, by adding various deodorants including oxygen / bacterial deodorants such as commercially available proteolytic enzymes, it is possible to eliminate the bad odor during the production of leaf soil. The practical effect of is extremely large.
