Description

Waste device that breaks down organic waste into bacteria

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a waste disposal device, commonly referred to as a "dissipation type," which disassembles and destroys organic waste such as kitchen waste, manure and industrial waste discharged from a food processing plant into bacteria.

The amount of organic waste generated every day is increasing. The amount of general waste generated by a person per day is about 1 kg, and the annual amount is 50 million tons. The amount of kitchen waste generated in each household is about 700g per day. In 100,000 households, 700,000 tons of kitchen waste is generated per day. In addition, a large amount of organic waste is generated in a food processing plant, and the amount of manure that cannot be dumped at sea is also a considerable amount. Organic wastes are incinerated and disposed of. Organic wastes have a very high moisture content and require large thermal energy for incineration. That is, because large heat energy is required to vaporize water. Therefore, it is a fact that a lot of expenses are spent on the disposal of organic waste. Instead of incineration, kitchen waste can be disintegrated into gases such as carbon dioxide, water, and ammonia by the action of bacteria, which eliminates the harm and reduces the energy consumed in disposal.

The treatment method for the use of bacteria to dissipate organic waste can be installed at each plant where the organic waste is generated, at a municipal waste disposal plant, or at a smaller scale. If there is a device that treats organic waste with bacteria at the place of occurrence and eliminates it, there is no need to transport the organic waste to the treatment plant. This makes it possible to realize an ideal disposal which is extremely efficient and low in cost, and does not need to dispose of the remaining residue such as a large amount of ash. Therefore, it is possible to save enormous expenses for the disposal of organic waste, and in addition, there is an extremely excellent feature that can be sanitized.

In this way, there are well known extinguishing devices for dissipating organic waste. Conventional extinguishing type treatment apparatus puts a microbial carrier crushed wood such as cedar in a particulate form in a casing that can be closed to inhabit bacteria therein. The organic waste is placed in a casing where bacteria live and air is continuously supplied while stirring continuously. Bacteria decompose and destroy organic waste into gases such as water vapor, carbon dioxide, ammonia and methane gas. Since organic waste is decomposed into gas, it almost disappears after treatment. The weight after the treatment becomes so light that it cannot be compared with the weight before the treatment. For this reason, organic waste can be injected daily and decomposed and lost. Since organic waste is lost, the total amount of microbial carriers does not increase even if organic waste is supplied daily.

It is important that a waste device that decomposes and destroys organic waste by the action of bacteia makes the environment in which bacteria inhabit a pleasant condition. It is also important to dissipate the organic wastes supplied uniformly and efficiently, and to actively move all the bacteria in the microbial carriers.

In order to realize this, the inventor has developed a waste disposal apparatus shown in the vertical longitudinal sectional view of FIG. 1 and the vertical lateral cross-sectional view of FIG. The apparatus shown in these figures rotates the casing (1) which supplies a microbial carrier and organic waste, the stirring blade (2) which stirs the microbial carrier and organic waste put into this casing (1), and the stirring blade (2). The reduction motor 4, the pressurized tank 5 for supplying pressurized air into the casing 1, the heater 6 for heating the air supplied to the pressurized tank 5, and the casing 1 It is provided with the temperature control circuit 7 which detects the air temperature to become, and controls the heater 6, and the pressurized air source 8 which supplies air to the pressurized tank 5. As shown in FIG.

The casing 1 has a lower half in a shape that fits into a cylinder, and is horizontally long and thin in overall shape, and a supply port 1A for supplying organic waste is opened in the upper portion. The supply port 1A is closed by a lid 9 that can be opened and closed. Inside the casing 1, the rotating stirring blade 2 is arrange | positioned horizontally. The stirring blades 2 are rotated to form spirals of opposite pitches so that the microbial carrier and organic waste can be moved left and right to be stirred. In addition, the stirring blade (2) is rotated close to the bottom surface of the casing (1) to stir the microorganism carrier and organic waste supplied into the casing (1) as a whole.

The waste disposal apparatus shown in FIG. 1 and FIG. 2 can decompose the supplied organic waste almost completely in tens of hours. However, it is difficult to uniformly stir the microorganism carriers and organic waste in the casing with an agitator blade in an ideal state. In particular, it is difficult to stir the whole of the microorganism carrier evenly by lightening the load of the motor that rotates the stirrer to reduce the damage of the microbial carrier. This is because the stirring blades in a spiral are moved by moving the microbial carrier and the organic waste from side to side at the same time. Microbial carriers that are forcibly transported and agitated in the horizontal direction are shortened to usable life. In particular, microbial carriers are difficult to have sufficient strength because porous ones having fine pores are used to inhabit bacteria. Porous microbial carriers include porous combinations of inorganic materials, wood chips or sawdust, chemical fibers or natural wood fibers, etc., cut into wood to form voids, foamed plastics, etc. It is used individually or in mixture of multiple types. These microbial carriers have a lower strength compared to the non-porous particle body. In addition, the higher the porosity of the microbial carrier, the more pores in which bacteria are inhabited.

Microbial carriers, which are difficult to have sufficient strength, fall off from the surface and become smaller when used for a certain period of time, thus degrading the bacterial environment. When the microbial carrier is abraded from the surface and becomes smaller, the habitat space of the bacteria becomes smaller and the function of the microbial carrier is reduced. For this reason, the microbial carriers which have become worn and small need to be replaced with new ones. The longer the life span of the microbial carrier can be used, the lower the running cost. In particular, the device that decomposes and destroys organic wastes by the action of bacteria is an important feature that can reduce the total amount of waste. Therefore, if it is necessary to dispose of microbial carriers frequently by replacing a large amount of microbial carriers, It cannot be saved effectively. For this reason, it is very important for this kind of device that the microbial carrier can be used for a long time, that is, to extend the life of the microbial carrier. It is also very important to make effective use of microbial carriers having a lot of fine pores and difficult to make sufficient strength for a long time.

The present invention was developed for the purpose of realizing this, and an important object of the present invention is to decompose organic waste which can be uniformly stirred in microorganism carriers and organic wastes in an ideal state so that the force does not act on the microorganism carriers by bacteria. It is to provide a waste disposal apparatus to disappear.

In addition, another important object of the present invention is to provide a waste disposal apparatus that decomposes and destroys organic waste into bacteria which can efficiently dispose a large amount of organic waste by reducing the overall installation area.

The waste device is agitated with the stirrer 10 while supplying air to the air supply port 11 to decompose and destroy the organic waste by bacteria inhabiting the microbial carrier.

Moreover, the waste disposal apparatus of this invention arrange | positions the casing 1 vertically, and arrange | positions the stirrer 10 which extends up and down in this casing 1, and conveys it to the direction which raises a microbial carrier and organic waste. The stirrer 10 is provided with the screw shaft 3 which fixes the screw pin 19, and the vertical cylinder 20 arrange | positioned at the outer periphery of this screw shaft 3. The screw shaft 3 rotating inside the vertical cylinder 20 raises the microbial carrier and organic waste along the vertical cylinder 20. The microbial carriers and organic wastes raised in the vertical cylinder 20 are discharged from the upper end of the vertical cylinder 20 and lowered in the casing 1.

In addition, the waste disposal apparatus of the present invention pipes so that the air injection pipe 26, which is an air supply port 11 for injecting air, extends up and down on the outer circumference of the vertical cylinder 20 so as to be detachable. (A) is an injection hole 26A for injecting air, and is opened in the longitudinal direction, and oxygen is injected from the air injection pipe 26 into the casing 1 to supply oxygen to the bacteria living in the microbial carrier. .

The microbial carrier and organic waste which are stirred in this state are stirred by convection in the casing (1). And it raises the inside of the vertical cylinder 20, and is stirred in the state which descends from the exterior of the vertical cylinder 20. As shown in FIG. The microbial carrier and organic waste in the vertical barrel 20 are lifted on the screw shaft 3. The screw shaft 3 raises the microbial carrier and organic waste to lift the spiral screw fin (19). The microbial carriers raised in this state are not in a pressed state, but are in a state in which horns are dispersed, and are lifted up by the screw pin 19 and are raised without difficulty. For this reason, the microbial carriers that rise inside the vertical cylinder 20 are not damaged, and the microbial carriers are raised by dispersing the microbial carriers so as to form voids therebetween. In addition, the microbial carriers discharged into the casing 1 from the upper end of the vertical cylinder 20 fall naturally and are sucked from the lower end of the vertical cylinder 20. The microbial carrier which naturally falls inside the casing 1 is not forcibly pushed by the stirring blade 23, but falls smoothly and without weight. For this reason, neither the microbial carrier which falls inside the casing 1, nor the microbial carrier which raises the vertical cylinder 20 is conveyed smoothly, without damage. In addition, the microbial carrier and organic waste which are stirred in the convection state which rises and falls in the casing 1 are stirred uniformly as a whole.

EXAMPLE

Embodiments of the present invention will be described below with reference to the accompanying drawings. However, the embodiment shown below is to exemplify a waste device that decomposes and destroys organic wastes into bacteria to embody the technical spirit of the present invention. It is not specific.

Disposal apparatus for decomposing and destroying organic wastes shown in FIG. 3 by bacteria includes a casing (1) for supplying microorganism carriers and organic waste, a stirrer (10) for agitating the microorganism carrier and organic waste supplied to the casing (1); In addition, the air supply port 11 for supplying air to the mixture of microbial carriers and organic waste to supply oxygen to the bacteria inhabiting the microbial carriers.

The casing 1 makes the whole shape into the shape which made the cylinder vertically, and makes the lower part taper shape. 1 A of openings of organic waste are opened in the upper end of the casing 1, and the outlet 1B is opened in the lower part. The supply port 1A and the discharge port 1B are occluded in the process of losing organic waste to bacteria.

The waste disposal apparatus of the present invention is used to discard both solid waste such as kitchen waste and liquid waste such as manure. Solid waste rarely remains when lost due to the action of bacteria. For this reason, the apparatus for processing solid waste can be thrown into the supply port 1A in turn and disposed of. Therefore, the discharge port 1B is used to open the microbial carrier and to discharge the microbial carrier.

However, liquid waste, such as manure, leaves water when the organic matter contained in the liquid is lost by the action of bacteria. Therefore, it is necessary to discharge the treated water from the discharge port 1B after treating the organic waste. When draining the treated water, it is necessary to install a porous material such as a metal net in the discharge port 1B so that the microbial carriers are not discharged at once.

4 and 5 are front and horizontal cross-sectional views of the portion of the discharge port 1B. The structure of the discharge port 1B shown in these figures opens the window in the casing 1, fixes the frame 12 at the periphery of the window, and connects the door 14 to the frame 12 via a hinge 13. have. Inside the door 14, the porous plate 15 which is a metal mesh is arrange | positioned. In addition, a drain pipe 16 is fixed to the door 14 for draining the water after the door 14 is opened. The door 14 is in close contact with the mold 12 through the packing so as not to leak from the mold 12 in the closed state. The door 14 tightly closes the window by screwing the opposite side to the hinge 13 to the frame 12.

The frame 12 is provided with sliding grooves 17 in both vertical frames so that the porous plate 15 can be pulled upward. The sliding groove 17 is provided so that the porous plate 15 which fixes a metal net to a rectangular frame can enter and leave. The porous plate 15 has a structure in which a punching plate and a metal net are laminated. The punching plate is disposed inside the casing 1, and a metal net is disposed outside the punching plate. The porous plate 15 having the punching plate disposed on the inner surface has a feature that can smoothly move the microbial carrier from the inside with sufficient strength.

Some doors 14 of the drain pipe 16 may drain the treated water in a closed state. The drain pipe 16 is connected to the drain pipe 18 via a drain valve.

The stirrer 10 has a screw shaft 3 which fixes the screw pin 19, and the vertical cylinder 201 arrange | positioned at the outer periphery of this screw shaft 3, The screw shaft 3 has a casing ( It is connected to the reduction motor 4 on the outside of 1). The stirrer 10 raises the microbial carrier and organic waste along the vertical cylinder 20 by the screw shaft 3 rotating inside the vertical cylinder 20. The vertical cylinder 20 is fixed perpendicularly to the center of the cylindrical casing 1 via an arm, and opens both upper and lower ends in the casing 1. The upper end of the vertical cylinder 20 is opened to the upper part of the casing 1 and the lower end is opened to the bottom of the casing 1.

The vertical cylinder 20 fixes the taper plate 21 to the periphery of the upper edge. The tapered plate 21 drops the microbial carrier and organic waste discharged from the vertical cylinder 20 to the outer circumference of the casing 1. The taper plate 21 is made of a metal plate in an umbrella shape, and the microorganism carriers and organic wastes supplied thereon are naturally dropped and uniformly dispersed in the casing 1. Organic waste, such as manure, supplied from the supply port 1A is also supplied onto the tapered plate 21 and dispersed and supplied to the casing 1. Therefore, in the apparatus shown in FIG. 3, the supply pipe 22 connected to the supply port 1A is opened above the tapered plate 21.

The screw shaft 3 is provided perpendicular to the center of the vertical cylinder 20. The screw shaft 3 penetrates the bottom of the casing 1 as a watertight structure which can rotate. The screw shaft 3 is connected so that the upper and lower parts may rotate to the casing 1 via a bearing. The bearing connecting the lower part of the screw shaft 3 to the casing 1 is of a watertight structure.

The screw shaft 3 is fixed to the outer periphery of the screw pin 19 that can rotate to raise the microbial carrier and organic waste along the vertical cylinder (20). Moreover, the deodorizing blade 23 which rotates along the bottom of the casing 1 is being fixed to the lower end of the screw shaft 3. The deodorant wing 23 prevents microbial carriers and organic waste from adhering to the tapered portion of the bottom surface of the casing 1.

The lower end of the screw shaft (3) is connected to the reduction motor (4) via the sprocket (24) and the chain (25) outside the casing (1), and is rotated by the reduction motor (4). The deceleration motor 4 rotates the screw shaft 3 by continuing the operation for a certain time after a certain time operation.

The air supply port 11 is provided with the two air injection pipes 26 which extend in the up-down direction and arrange | position vertically on the outer periphery of the vertical cylinder 20. As shown in FIG. The air injection pipe 26 opens with the injection port 26A which injects air at a fixed interval in the longitudinal direction, as shown in FIG. The injection port 26A injects air toward the outer side of the casing 1. The injection hole 26A of the air injection pipe 26 may be blocked. In order to simply clean the clogged injection port 26A, the air injection pipe 26 is connected to the vertical cylinder 20 so as to be withdrawn. The vertical cylinder 20 fixes the ring 27 into which the vertical injection pipe 26 is inserted in the outer periphery. The ring 27 is fixed in two rows in the vertical cylinder 20, and the air injection pipe 26 is inserted into each ring 27 from top to bottom. Moreover, the air injection pipe 26 is a shape which can be easily inserted in the ring 27 by making the lower end into a taper shape with a thin tip. The air injection pipe 26 of this structure is characterized by being easily inserted into and detached from the ring 27 of the vertical cylinder 20.

Air injected into the casing 1 from the air injector 26 supplies oxygen to the bacteria inhabiting the microbial carrier. In addition, by controlling the temperature of the air injected from the air injection pipe 26, it is possible to adjust the temperature of the microbial carrier to the temperature at which the bacteria actively move. The optimum temperature for bacteria to grow comfortably and actively break down organic waste is 38-50 ℃. When the temperature drops below 38 ° C, the bacteria become inactive. If the temperature is below 50 ° C, the aerobic bacteria cannot be actively moved, and the anaerobic bacteria grow. The growth of anaerobes worsens the smell of the emitted gases. When the temperature of the microorganism carrier becomes higher than 50 ° C., a large amount of outside air can be injected into the casing 1 to achieve a comfortable temperature.

However, in winter, when the temperature of the outside air is too low, when the outside air is injected into the casing, the temperature of the microbial carrier is too low to effectively decompose the organic waste in a short time. This hazard can be heated by embedding a heater in the casing or heating the vertical barrel with a heater to warm the microbial carrier.

In addition, the temperature of the microbial carrier can be controlled by heating the air injected from the air injection pipe 26. An air injection pipe 26 for injecting temperature controlled air is connected to a pressure tank 5 for accumulating temperature controlled air. The pressurized tank 5 is connected to pressurized air sources 8, such as a blower and a compressor, and accumulates pressurized air heated to a preset temperature. The pressurized tank 5 accumulates pressurized air at, for example, 0.1 to 10 kg / cm 2. A flow rate control valve 28 is connected between the pressurized tank 5 and the air injection pipe. The flow rate control valve 28 adjusts the degree of opening to adjust the amount of air and the injection pressure to be injected from the air injection pipe 26. When the flow rate control valve 28 is opened narrowly, the amount of air to be injected decreases, so that the injection pressure decreases. The injection amount of air is adjusted to an optimum value in consideration of the capacity of the casing 1. The casing 1 having a throughput of 300 kg per day sets the injection amount of air to, for example, 0.1 to 2.5 m 3 / min, preferably 0.2 to 1.5 m 3 / min, more preferably 0.3 to 1 m 3 / min. The air pressure injected from the air injector 26 to the casing 1 is, for example, 0.1 to 0.5 kg / cm 2, more preferably about 0.2 kg / so that the injected air can pass through the gap between the microbial carrier and the organic waste. Set to cm 2.

The pressurized tank 5 fixes the heater 6 outside to heat the air accumulated inside to the set temperature. The outside of the heater 6 is insulated to prevent heat radiation. The heater 6 for heating the pressurized tank 5 is attached in series to the switch 29 and the power supply 30. When the switch 29 is ON, the heater 6 is energized to heat the pressure tank 5. The switch 29 for controlling the power supply of the heater 6 is controlled by the temperature sensor 31 which detects the temperature of the microbial carrier or detects the temperature of the discharge side of the flow regulating valve 28, Adjust the air temperature of the pressure tank (5). The set temperature of the air accumulated in the pressure tank 5 is set to a temperature at which the temperature of the microorganism carrier is, for example, 38 to 50 ° C, preferably 38 to 45 ° C.

When the ambient air temperature around the casing 1 is set to 15 ° C. or less, the temperature of the microbial carrier becomes slightly higher than the air temperature injected from the air injection pipe 26. In particular, when the microorganism carrier actively decomposes the organic waste, in other words, when the organic waste is supplied for 2 to 3 hours, the temperature of the microbial carrier becomes considerably higher than the ambient temperature. This is because microorganisms actively decompose organic waste. After the next day of injecting organic waste, that is, about 24 hours, the organic waste is almost completely decomposed and lost, and the temperature of the microbial carrier decreases. The method of controlling the air temperature of the pressurized tank 5 by detecting the temperature of the microbial carrier is to set the air temperature of the pressurized tank 5 low when the microbial carrier actively decomposes the organic waste, and the microbial carrier completely removes the organic waste. After disassembly, the air temperature of the pressurizing tank 5 is set high. This method is characterized by the ability to always control the temperature of the microbial carrier to the ideal temperature.

The waste disposal apparatus shown in FIG. 3 decompose | disassembles and loses solid or liquid organic waste as follows.

① Put the microbial carrier of bacteria in the casing (1). The microbial carrier is preferably a porous material obtained by grinding wood such as cedar into particulates. Porous microbial carriers are inhabited by a myriad of bacteria. Bacteria that inhabit microbial carriers are aerobic bacteria, basic bacteria, and communicable basic bacteria. In addition, bacteria are added to the microbial carrier, and enzymes are preferably added. As shown in Fig. 3, the amount of the microbial carriers filled in the casing 1 is such that the top level of the microbial carriers is located below the upper end of the vertical cylinder 20.

(2) Injecting air from the air injection pipe (26) while putting the microbial carrier in the casing (1). Air injected from the air injector 26 passes through the gap of the microbial carrier to warm the microbial carrier to a set temperature. The air temperature injected from the air injection pipe 26 is set at a temperature for heating the microbial carrier to about 38 to 50 ° C, preferably 38 to 45 ° C. The flow rate and injection pressure of the air injected into the casing 1 are adjusted by the flow regulating valve 28. The apparatus for accumulating 5 m 3 of microbial carriers in the casing 1 sets the air pressure supplied to the air injection pipe 26 to 0.15 kg / cm 2 and 0.4 ° C./min. The air injection pipe 26 continuously injects air.

③ Supply organic waste while rotating the screw shaft (3). Liquid organic waste is supplied on the tapered plate 21 from the supply pipe 22. When supplying the organic waste, the screw shaft 3 is rotated to sufficiently mix the organic waste with the microbial carrier. The screw shaft 3 raises the microbial carrier and organic waste to the vertical cylinder 20 to convection to fall between the vertical cylinder 20 and the casing 1 to agitate the microbial carrier and the organic waste.

④ The screw shaft (3) is mixed with the organic waste and the microbial carrier sufficiently and then rotates intermittently to stir the organic waste and the microbial carrier. The screw shaft 3 is, for example, rotated for 5 minutes and stopped for 1 minute thereafter. The stirring time can be 2 to 20 minutes. The resting time of the screw shaft 3 can be made into 20 minutes-2 hours. If the idle time is increased with respect to the rotation time, the amount of electricity consumed by rotating the screw shaft 3 can be reduced. However, if the down time is too long, the microorganism carriers and organic wastes cannot be sufficiently agitated and thus cannot be effectively decomposed and lost.

⑤ When the air injection pipe 26 is continuously supplied with air by stirring intermittently in the screw shaft 3, the bacteria inhabiting the microbial carrier decomposes organic waste into gases such as carbon dioxide, water, ammonia and the like. Bacteria inhabiting microbial carriers proliferate rapidly after several hours of supplying organic waste, which actively decomposes organic waste. When organic waste is put in for 24 hours, that is, the next day, organic waste is almost completely decomposed and lost.

Disposal device for decomposing and destroying the microbial carrier of the present invention to bacteria has a feature that can uniformly stir the microbial carrier so as not to force the microbial carrier. This is because the device of the present invention extends up and down in the casing to install a vertical cylinder, and rotates the screw shaft inside the vertical cylinder to raise the microbial carrier and organic waste. The microbial carriers rising inside the vertical barrel are moved in a state of being lifted upward by the pins of the screw shaft. Since the microbial carrier to be dropped to its own weight is lifted and moved in the opposite direction to the dropping direction, the microbial carrier is transported in a state of being separated up and down, and is smoothly lifted up without difficulty. The microbial carrier which raises the vertical cylinder is transported in the casing from the upper end of the vertical cylinder, but does not drop to the own weight and is not forcibly transported in the casing. In particular, the microbial carriers falling in the casing are raised from the bottom and fall to their own weight, so they fall extremely smoothly. For this reason, the microbial carrier has a feature that can be used for a long time by significantly reducing damage without causing excessive pressure in the state of falling down the casing when the vertical cylinder is raised.

For this reason, the microbial carrier has a feature that can be used for a very long time because the pores that inhabit the bacteria are not filled and the whole wears small. Therefore, the apparatus of the present invention has a feature that can lengthen the time for exchanging the microbial carrier with a new one, simplify the maintenance and reduce the running cost.

In addition, the bacteria of the present invention can be agitated in a convective state by raising the microbial carriers and organic wastes in a vertical tube, and supplying them into the casing from the top and dropping them, so that the microbial carriers and organic wastes are not uniformly mixed. It is also possible to realize a feature that can be stirred.

In addition, the waste disposal apparatus of the present invention can make the casing vertical and stir the microorganism carriers and organic wastes in an ideal state, so that a feature that can efficiently dispose a large amount of organic wastes by reducing the total installation area can be realized. .
