Description

  The present invention is a fermented agitation used for fermenting and composting agricultural resource waste, livestock waste, agricultural settlement drainage sludge, sewage sludge, food waste, aquatic resource waste, wood resource waste. The present invention relates to a processing apparatus and a method for producing compost. In particular, even if an excessive load is applied to the screw blade rotating stirrer, it is possible to continue automatic operation without hindering work, such as a fermentation stirring processing apparatus and compost excellent in safety, workability and energy efficiency. It relates to the manufacturing method.

  In recent years, sludge treatment has become a serious issue for small and medium-sized food processing, fishery processing, intermediate processing companies, and small and medium livestock producers. Agricultural resource waste sludge, livestock waste sludge, agricultural settlement drainage sludge, sewage sludge, food Waste sludge, aquatic resource waste sludge, and livestock excreta disposal have become serious problems that have become more serious in conjunction with amendments to the ordinance (prohibition of field loading, etc.).

  Under such circumstances, a method is adopted in which a sludge is dehydrated using a polymer flocculant, microorganisms are added to livestock manure and livestock manure sludge, fermented, and stirred and composted at a moisture content of 60% to less than 50%. It has been. This compost fermentation process reduces the molecular weight of macromolecules by microbial degradation of slaughterhouse sludge, fat, fiber, protein, and other organic matter as the main component when blood is contained in a lot. It is transformed into organic fertilizer with a uniform component. Specifically, a composting facility is known in which microorganisms are introduced into a compost house that stores sludge, and is automatically stirred and fermented by a stirring device.

  In addition, the sludge treatment from the purification facility was dehydrated by adding a polymer flocculant, and the sludge with a cake-like water content of 80% or more was further dehydrated and placed in a stirring tank. In this method, the running cost of the processing costs is high, but it is difficult for small and medium-sized enterprises and livestock farmers to introduce large-scale composting facilities and large-scale fermentation agitators. At present, stirring work is performed using a car or the like. For this reason, there has been a strong demand for a small-sized fermentation stirring apparatus capable of directly agitating sludge and animal manure without directly adjusting the moisture even in such a small compost house.

  Furthermore, in the treatment of organic waste such as raw garbage, many methods are employed in which microorganisms are added to the waste and subjected to fermentation and composting. In this fermentation treatment method using microorganisms, organic matter is fermented and decomposed by microorganisms, and then transformed into organic fertilizers mainly composed of uniform low-molecular compounds. For example, there is a method in which microorganisms are put into livestock dung stored in a composting facility having a relatively large area, and the livestock dung is stirred by a large-scale scoop type and rotary type stirrer.

  Furthermore, in recent years, various improved techniques have been reported in the treatment of human waste or livestock manure. For example, a manure processing plant that secures the gas components generated in the gas venting tank and the heating evaporation chamber as auxiliary fuel for heating in the heating evaporation chamber and takes out the solid components left in the heating evaporation chamber as needed to make fertilizer (Patent Document) 1) and a fermenting and stirring apparatus for livestock excreta suitable for use in a small-scale composting house that fermentes manure (see Patent Document 2).

In the manure processing plant described in Patent Document 1, the manure continuously fed into the degassing tank is agitated and degassed from the storage tank for temporarily storing the introduced manure, and the manure in the degassing tank is heated in the heating evaporation chamber. Moisture is evaporated by a spraying device that sprays the heating plate, and the water evaporated in the heating evaporation chamber is placed under the cooling plate with a cooling plate having a vent hole disposed so as to cover the ceiling in the heating evaporation chamber It is liquefied by a liquefying device composed of a receiving bowl arranged. In addition, the fermentation stirring apparatus described in Patent Document 2 is installed on the upper open surface of a tank for storing livestock excrement, and is provided with a gantry reciprocated back and forth, and suspended from the gantry, and reciprocates left and right on the gantry. It is comprised from the moved rotary stirring body.

Below, with reference to drawings, embodiment in the manufacturing method of the fermentation stirring processing apparatus and compost of this invention is described.
A fermentation stirring treatment apparatus 1 according to a preferred embodiment of the present invention shown in the figure is installed on a fermentation tank 2 for storing and fermenting organic waste, and on the upper open surface of the fermentation tank 2 so as to be able to reciprocate back and forth. And a pair of screw blade rotating stirrers 10 that are suspended from the mount 3 and have an air outlet 15 at at least one tip, and the screw blade rotating stirrer 10 has a limit load. An automatic irregular means 16 for changing the rotational drive transmission ratio is sometimes arranged between the drive means 17 for the screw blade rotating agitator 10 and the screw blade rotating agitator 10.

  Fermenter 2 ferments and composts crushed mixtures of agricultural resource waste, livestock waste, agricultural settlement drainage sludge, sewage sludge, food waste, aquatic resource waste, wood resource waste, etc. The interior is divided into a plurality of sections by the concrete wall 4. In addition, on the upper surface of the concrete wall 4, a rail 5 for moving back and forth extending in the front-rear direction is laid.

  The screw blade rotating stirrer 10 is installed at the top of the fermenter 2, and the main members of the screw blade rotating stirrer 10 are arranged on the gantry 3. The gantry 3 is movable in the front-rear direction and the left-right direction of the fermenter 2 via the front-rear movement wheel 6 and the left-right movement wheel. That is, the front and rear movement wheels 6 are fitted on the front and rear movement rail 5 so as to be able to travel in the front and rear direction.

  Compost from fermenter 2 has a good fermentation efficiency and is homogeneously matured to maintain optimum performance as a soil improvement material. Weeds, seeds, pest eggs, pathogens, spoilage bacteria, etc. are generated by heat generated during fermentation. Become dead. Then, the compost fermented at a high temperature by the primary fermentation is carried into the secondary fermenter of the secondary fermentation compost house, and the excavator is turned over to produce a fully-ripened organic fertilizer. The organic fertilizer thus obtained can be used as a fertilizer for vegetables, etc. in an adjacent hot water house, and the remaining compost can be sold.

  In the preferred example shown in FIGS. 2 and 3, the screw blade rotating stirring body 10 includes a pair of hollow stirring shafts 11 and a blade member 12 attached to the stirring shaft 11. Further, the lower end of the stirring shaft 11 reaches the vicinity of the floor surface of the fermenter 2. The stirring shaft 11 is provided with an inlet 13 for injecting livestock urine and scum containing a lot of water, and a sanitary pipe 14 for preventing clogging is disposed in at least one of the stirring shafts 11. It is installed. Further, the tip of the sanitary pipe 14 is bent, and an air outlet 15 is provided at the tip. In the sanitary pipe 14, livestock urine and sake lees containing a lot of water circulate, and a mixture of warm air and livestock urine water is ejected from the air outlet 15 into the crushed mixture.

  The screw blade rotating agitator 10 has a mechanism that emits air from the tip of the agitation shaft 11 with little heat dissipation in the fermenter 2 during agitation, high sustainability of high-temperature fermentation, and a conventional agitator. Therefore, since the primary treatment capacity is high and the amount of movement of compost is smaller than that of a conventional stirrer, the length of the fermenter 2 can be shortened. For example, in the case of the rotary type, when the height of the fermenter is 1.5 m, the width is limited to 5 m, whereas the height of the vertical stirrer is 2 m and the width is 10 m, and the volume can be greatly increased. The amount of processing also increases. Also, since bearings and the like do not directly enter the workpiece, there are few failures and the structure is simple and maintenance is easy.

  The crushed mixture that has been mixed and pressurized in this way has a fast rise and high-temperature fermentation, so that it matures in a short period of time and becomes high-quality compost. That is, fermentation treatment can be promoted by rotating and stirring in the vertical direction. In particular, the fermentation treatment efficiency can be greatly increased because the lower layer portion near the floor of the treatment tank can be pulverized and stirred and sufficiently aerated. Furthermore, by dispersing a mixture of warm air and animal urine water from the tip of the screw into the fermented compost during the agitation, the lump of waste collected in the vicinity of the agitation shaft 11 can be finely pulverized. Can be reliably dispersed.

  In the present invention, the automatic anomaly means 16 for changing the rotational drive transmission ratio when a limit load is applied to the screw blade rotating agitator 10 includes the driving means 17 for the screw blade rotating agitator 10 and the screw blade rotation. It is important to arrange it between the stirrer 10.

  The automatic anomaly means 16 can use a full sync clutch gear, a magnet clutch gear, a torque converter, or the like. The auto anomaly means 16 itself is a drive means for the screw blade rotating agitator 10 according to a commonly used mechanism in an automobile or the like. What is necessary is just to apply suitably between 17 and this screw blade rotation stirring body 10. FIG. When a torque converter is used, the rotational force of the drive means 17 can be transmitted to the rotating shaft 18 using hydraulic pressure by flowing automatic oil instead of connecting the clutch plate.

  For example, the automatic irregular means 16 attaches a torque converter with an automobile mission to the rotating shaft 19 of the driving means 17 composed of a motor, and adjusts the hydraulic pressure to a 1: 1 rotation ratio in advance. Initially, the driving means 17 is operated at a low speed, and when an excessive load is applied to the screw blade rotating agitator 10, the sensor rotates from the low speed to the maximum rotation speed of the motor output. At this time, for example, the torque converter releases the resistance of the load with a gear ratio of 1: 3. Thereby, the screw blade rotating stirring body 10 can continue to operate without stopping due to an excessive load. When the load is reduced, the gear ratio returns to 1: 1, and the operation is not interrupted and automatic operation can be performed without causing any trouble.

  In the case of a mission with a clutch, for example, a full synchro gear is inserted between the rotating shaft 19 of the driving means 17 and the transmission gear of the screw blade rotating agitator 10, and the clutch disk is connected to the clutch desk. For example, when the load is hung on the screw blade rotating agitator 10 in accordance with the rotation of 1: 1 at the beginning, the synchro gear automatically guides and connects the 1: 3 gear when the clutch disk starts to slide with the load, The screw blade rotating stirring member 10 is rotated without any trouble. After that, when the load is overcome, the gear returns to 1: 1. It is also preferable to use a magnet clutch gear depending on the work contents. By providing the torque converter, the full synchro clutch gear or the magnet clutch gear automatic irregular means 16, automatic operation can be performed without requiring manual operation at midnight. In addition, the use of midnight power can reduce electricity costs and increase the number of stirring rotations, so economic effects and labor cost reduction can be expected. Furthermore, in the daytime, you can concentrate on deodorizing measures.

  As shown in FIG. 4, for example, the torque converter used for the automatic irregular means 16 includes a torque converter main body 32 and an oil pump 33. However, the screw blade rotating agitator 10 has a limit load. The structure is not particularly limited as long as the rotational drive transmission ratio is changed.

  Moreover, it is preferable to form so that the rotation direction of a pair of stirring shaft 11 of the screw blade | wing rotation stirring body 10 may mutually differ. By forming the stirring shaft 11 so that the rotation directions thereof are different from each other, the blade members 12 rotate so as to engage with each other, so that sludge can be efficiently crushed without clinging to the blade members 12.

  Furthermore, as shown in FIG. 5, a pair of screw blade rotation stirring body 10 is attached so that it can incline toward the advancing direction. The sludge can be fed and returned in the best condition by stirring by taking an angle so that the screw blade rotating stirring body 10 is inclined by 30 degrees toward the traveling direction. In addition, a convection phenomenon occurs during agitation, and the sludge returned toward the inlet can be repeatedly agitated while dragging the sludge before agitation, so that the best exothermic fermentation is promoted.

  Furthermore, it is preferable that the blade member 12 of the pair of screw blade rotating agitators 10 can be replaced. The rotationally rotating portion at the tip of the blade member 12 has the longest contact time with the sludge that is the processed material, and wear from the tip to the middle is remarkable. Therefore, a great cost is required to replace the entire blade member 12 when it is worn. In consideration of this cost, it is desirable to fix the reinforcing plate 30 to the blade member 12 at a place where the wear is severe as shown in FIG. The reinforcing plate 30 is formed of a strong metal plate, and a plurality of the reinforcing plates 30 are fixed to the blade member 12 by a fixture 31 made of a hexagonal screw or the like. Thus, only the worn part of the blade member 12 can be reinforced, and the cost can be reduced.

  As another suitable example of the fermentation stirring processing apparatus of this invention, as shown to (a) (b) of FIG. 7, while crushing a waste material to a pair of screw blade rotation stirring body 10, it is a bottom part. The crushing device 23 that feeds the waste material to the upper part can be provided. The crushing device 23 includes, for example, a rotating shaft 24 and a blade portion 25 installed around the rotating shaft 24, and is disposed in an intermediate portion of the pair of screw blade rotating agitators 10. Further, the blade portions 25 are formed in a state inclined in a direction opposite to the inclination direction of the blade member 12, and each blade portion 25 is disposed between the blade members 12 of the screw blade rotating agitator 10. As a result, by rotating the screw blade rotating agitator 10 and the crushing device 23 in the direction of the arrow, the large-sized waste is crushed into small pieces by the blade portion 25 during the stirring operation, and the waste at the bottom is removed. It can be sent to the top.

  Moreover, as another suitable example of the fermentation stirring processing apparatus of this invention, the mount frame 3 is equipped with the vehicle tire (for example, pneumatic tire) 7, and it can be set as the structure which drive | works on the rail 5 for front-back movement. When the load is most applied to the screw blade rotating agitator 10, the load can be reduced by the automatic irregular means 16. However, an excessive load is also applied to the screw blade rotating agitator 10 itself installed on the gantry 3, and the impact is transmitted to the front and rear moving rail 5 that supports the gantry 3 and the wheels that run on the rail. Therefore, if the gantry 3 is provided with the vehicle tire 7 and travels on the rail for forward and backward movement, the air pressure of the vehicle tire 7 becomes a suspension that reduces the impact, and the smooth operation is advanced and the durability of the rail 5 is improved. Sexuality can also be enhanced.

  Furthermore, as another preferable example of the fermentation stirring processing apparatus of the present invention, the drive means 17 is a vehicle engine, and the motor (not shown) is driven by the electric power generated by the power generation by the vehicle engine for the movement of the gantry 3. It is preferable to carry out. By using the vehicle engine for the driving means 17, the stirring is not burdened by the torque converter, and the screw blade rotating stirring body 10 can be operated. In addition, the motor for moving the gantry 3 uses the rotation of the engine to generate electricity, the gantry 3 with the vehicle tires 7 attached can be removed, and the gantry 3 can be widened or packed by connecting with a joint. It becomes. Thereby, it becomes a general purpose stirrer that can be moved and installed in a place where electricity cannot be taken or in other facilities. Furthermore, circumferential stirring can be performed by fixing either the left or right of the gantry 3.

  In the preferred example shown in the figure, a water distribution pipe 20 is provided on the inner side surface of the fermenter 2 to extract hot water by fermentation heat. Compost treated with only organic matter with high carbon content is dried, and edible waste oil is mixed with RDF (solid fuel), and the heat distribution from the water pipe 20 arranged by the inner side surface of the fermenter 2 The heated hot water is taken out, the hot water is steamed using RDF fuel made from compost, and the hose is connected to the compressor, so that it can be sent to the tip of the screw blade rotating agitator 10. Moreover, warm water can also be sent to a livestock barn or a warm water house.

  Further, in the preferred example shown in the figure, the water distribution pipe 20 is provided with a compressor 21 that pressure-feeds steam obtained by further heating the hot water to the air outlet 15 of the screw blade rotary stirring body 10. Thereby, the pressure is increased by the compressor 21, and the hot water heated by the fuel can be sprayed in a mist form from the air outlet 15 of the stirring shaft 11.

  Moreover, it is preferable to arrange | position the injection pipe 22 which has the steam injection port for a blow as shown in figure in the fermenter 2 bottom part and organic waste input port vicinity. By submerging a plurality of perforated pipes and blowing them with steam so that the jet pipe 22 can be moved to the floor surface of a portion with high moisture, the water is adjusted well from anaerobic to aerobic. be able to.

Next, the production method of the present invention will be described in detail.
In fermenting and composting organic waste using the fermented stirring treatment apparatus 1 of the present invention, first, organic waste having a water content of 90% or more is put into the fermenter 2. Next, the thrown-in organic waste is sparged with warm air from the tip while moving the screw blade rotating stirrer 10 left and right, and at the same time stirred while moving the gantry 3 forward to gradually transform into a hard clay. Let At this time, stirring is performed until the blade member 12 adjacent to the screw blade rotating stirring body 10 is crushed into fine particles. The organic waste to be treated is stirred and stirred from the bottom of the fermenter 2 by the hot air blown from the tip of the screw blade rotating stirrer 10, so that it is evenly exposed to aerobic conditions, and microorganisms are activated. Go ahead and produce high quality compost.

  Moreover, since the heat of fermentation stirred by the screw blade rotating stirring body 10 is high and a large amount of steam is generated, the steam generated during fermentation can be collected and recovered as liquid fertilizer. Moreover, the produced compost is returned to the fermenter 2 and recirculated to increase the compost volume reduction rate, so that only a quarter of the quarter used by farmers throughout the year can be used. And keep the stock yard to a minimum. Furthermore, the pair of screw blade rotating stirrers 10 are stirred at an inclination of about 30 degrees with respect to the vertical line in the traveling direction, so that sludge can be fed and returned in the best condition, a convection phenomenon occurs, and Return sludge can be stirred repeatedly while dragging the sludge before stirring, and the best exothermic fermentation is promoted.

Hereinafter, the present invention will be described based on examples.
Under the following conditions, fermentation stirring treatment was carried out using the fermentation stirring treatment apparatus of the present invention provided with a screw blade rotating stirring body having automatic irregular means.

・ Motor: 15KW (Geared type induction motor)
・ Air supply: 1.5 atm

  From the sludge to the clay, a rheological effect occurred at a distance of 8 m at an external temperature of 20 ° C. The number of days up to that point was about 5 days. It took about 10 days until pyrogenic fermentation started. From this point, the clay began to swell, the water content reached 60%, filamentous fungi began to develop rapidly, and the amount of heat began to increase. The water began to evaporate and transformed into a hard clay to promote fermentation. The moisture was 50% or more and less than 60%, and the finished compost was reduced to 1 in 3 minutes. In the apparatus of the present invention, even if the livestock excreta and animal urine were transformed into a hard clay, the automatic irregular means of the screw blade rotating stirrer acted and the screw blade rotation could continue to operate without stopping.

  Moreover, the sediment in the state of livestock manure and urine is slowly stirred while sending warm air of 60 ° C or higher, so that the 2m fermenter forcibly keeps the accumulated heat without releasing the heat. However, forced fermentation was possible.

  Next, FIG. 8 schematically shows a cross-sectional compost state in the fermenter when composting is performed for 47 days in the fermenter. Ten tons of urine was added every day, and a total of 210 tons of urine was added in three weeks. Thereafter, 6 tons of urine was added every day and 3 to 6 tons from the middle.

  As compost, a better product than scoop and rotary stirring was obtained. In addition, 30% to 40% of the back compost was put into the fermentor according to the amount of manure adjusted for water mixed in the basket that came out of another pig house.

  In the figure, a is a return / feces basket, b is muddy sludge, c is soft clay, and d is ordinary clay. These sludges became anaerobic. In part e, the surface temperature before stirring was 70 ° C., and the inside rose to 80 ° C. by stirring. In the part f, the surface temperature before stirring is 65 ° C. and the internal temperature after stirring is 70 ° C. In the part g, the surface temperature before stirring is 45 ° C., the internal temperature after stirring is 65 ° C., and in the h part, the internal temperature is 45 ° C. Met.
