Description

Compost fermentation equipment {COMPOST FERMENT EQUIPMENT}

The present invention relates to a compost fermentation apparatus for producing compost by fermenting livestock manure. More specifically, the present invention relates to an apparatus for producing organic fertilizer by fermenting manure of cows, pigs, chickens, etc. with microorganisms or the like.

Recently, due to the commercialization of the livestock industry, a large amount of livestock waste discharged from livestock farms has been generated, and the generated livestock meal has emerged as a major cause of environmental pollution. For this reason, a lot of research is being conducted on the effective treatment of livestock manure and furthermore, the recycling of livestock manure.

As one of the methods for recycling livestock manure, there is a method of composting livestock manure by fermenting it with microorganisms or the like.

Korean Utility Model Registration No. 20-0307532 discloses a technology related to a fermentation device for making organic fertilizer by stirring and fermenting manure.

Referring to FIG. 1, the compost fermentation device in the registered utility model includes a fermentation tank (1) in which livestock manure is loaded and fermented, an air supply pipe insertion groove (2) formed at a predetermined interval on the bottom of the fermentation tank (1), and the air supply pipe is inserted. An air supply pipe (3) inserted into the groove (2) to supply air to the livestock meal loaded in the fermenter, a valve (4) to control the air flow in the air supply pipe (3), and a blower to inject air into the air supply pipe (3) (5) and an agitator (6) for agitating the livestock contents loaded in the fermenter.

The air supply pipe is made in the form of a pipe, and a plurality of air discharge holes are perforated. The air supply pipe is buried in the bottom of the fermentation tank in which the livestock meal is loaded, and supplies air to the livestock meal loaded in the fermentation tank, so that the loaded livestock meal is actively fermented by microorganisms.

In the process of supplying air to the air supply pipe, if livestock manure, etc., loaded on the upper side flows into the pipe through the air discharge hole and accumulates, or if the pipe is blocked by the inflow of livestock manure, etc., smooth air supply to the loaded livestock manure is not achieved, resulting in compost. The fermentation efficiency of the fermentation device is lowered.

In this way, if a problem occurs in the air supply pipe, in the conventional case, after transferring all the livestock contents loaded in the fermenter to another place, large-scale work such as removing and cleaning or replacing the air supply pipe buried in the bottom surface had to be performed. As such, the conventional air supply pipe is not easy to maintain, and there is a problem that cost, manpower, and time are enormously required during maintenance.

On the other hand, in order for the fermentation of livestock meal to occur efficiently, the livestock meal in the fermenter should be properly maintained at a temperature of about 60 ° C to 65 ° C. Conventionally, this has been tried to solve this problem by heating the entire compost fermentation device, but when the entire compost fermentation device is heated in this way, there is a problem in that the cost required for heating is excessive.

It is a view showing the separation, and FIG. 5 is a view showing the separation of the lower plate in FIG. 3 .

2 to 5, the compost fermentation apparatus 10 includes a fermentation tank 500 in which livestock meal is loaded and fermented, an agitator 700 for stirring livestock meal loaded in the fermentation tank, and air supplied to the livestock meal loaded in the fermentation tank. An air supply pipe 100, a blower 900 for providing air to the air supply pipe 100, a hot water circulation pipe 300 for heating livestock loaded in the fermenter with hot water, and hot water supplying hot water to the hot water circulation pipe 300 A pump (not shown) may be included.

The compost fermentation device 10 may be a device for reproducing compost by fermenting various organic wastes. Organic waste refers to wastes mainly composed of organic substances, such as household waste such as food and livestock manure, which is livestock manure. For convenience of description, only livestock manure will be described below.

The fermentation tank 500 may be a place where livestock contents input from the outside into the compost fermentation device 10 are loaded. The introduced livestock manure is fermented and composted for a certain period in the fermentation tank 500, and the composted livestock manure is released as compost. The fermentation tank 500 may be an open fermentation tank installed in a place such as an open field or a closed fermentation tank installed in a separate facility.

The stirrer 700 may be a device for stirring the livestock contents loaded in the fermenter 500. The agitator 700 artificially agitates the livestock meal loaded in the fermentation tank 500 to perform aerobic fermentation.

When the livestock meal is stirred, the fermentation efficiency can be increased by supplying enough air to the microorganisms as well as evenly spreading the microorganisms undergoing fermentation in the livestock meal compared to the case where the livestock meal is not stirred.

The stirrer 700 has a stirring escalator and may be a fermentation stirrer that reciprocates along rails formed on the upper surfaces of both side walls of the fermentation tank 500.

The agitation escalator can stir the livestock meal through a process of raising and dropping the livestock meal loaded in the fermenter 500 while the bucket capable of scooping the livestock meal circulates.

The air supply pipe 100 extends in one direction at the bottom of the fermentation tank 500 in which livestock meal is stored, and supplies heated air to livestock meal loaded in the fermentation tank 500.

In order for livestock manure to be fermented efficiently, it is necessary to maintain an appropriate temperature at which fermentation of microorganisms added to livestock manure can occur actively. When air at room temperature is supplied to livestock manure, it is difficult to maintain an appropriate temperature required for fermentation in the fermenter 500, and the fermentation efficiency of livestock manure is reduced. On the other hand, when air heated to an appropriate temperature is supplied, an appropriate temperature required for fermentation can be maintained in the fermenter 500, so that the fermentation efficiency of livestock manure can be improved.

The air supply pipe 100 may be formed with a plurality of air discharge holes 111 for supplying heated air to shaft powder loaded thereon.

The air supply pipe 100 is parallel to the bottom of the fermenter 500, and may be installed extending in a direction perpendicular to the direction in which the loaded livestock meal is transported or in a direction in which the loaded livestock meal is transported.

The air supply pipe 100 may receive air from the blower 900 .

The blower 900 that supplies air to the air supply pipe 100 is a device that causes the flow of air, and uses an impeller that causes the flow and a casing that guides the flow that goes in and out of the impeller to flow the air. can cause

Air supplied to livestock meal through the air supply pipe 100 may be heated air. Specifically, the air inside the air supply pipe 100 may be heated by hot water passing through the inside of the hot water circulation pipe 300 and then supplied as axis powder. The air supply pipe 100 may receive air heated by the blower 900 and supply it as shaft powder.

The temperature of the air heated in the air supply pipe 100 may be a temperature at which livestock manure loaded in the fermenter 500 can be heated to a temperature suitable for fermentation.

Conventionally, fermentation efficiency is reduced by supplying air at room temperature to the fermentation tank 500 as it is even during low-temperature periods such as winter. In the present invention, the hot water circulation pipe 300 is accommodated inside the air supply pipe 100 to supply heated air to livestock meal, thereby maintaining an appropriate temperature for fermentation of livestock meal, thereby improving fermentation efficiency.

In order for livestock manure to be fermented efficiently, it is necessary to maintain an appropriate temperature at which fermentation of microorganisms added to livestock manure can occur actively. When air at room temperature is supplied to livestock manure, it is difficult to maintain an appropriate temperature required for fermentation in the fermenter 500, and the fermentation efficiency of livestock manure is reduced. On the other hand, when air heated to an appropriate temperature is supplied, an appropriate temperature required for fermentation can be maintained in the fermenter 500, so that the fermentation efficiency of livestock manure can be improved.

The air supply pipe 100 has an upper plate 110 and a lower plate 130 coupled to the upper plate 110 .

The upper plate 110 is in contact with livestock manure stored in the fermenter 500.

The upper plate 110 may be fixedly installed on the bottom of the fermentation tank 500 so as not to be moved by the shaft powder being stirred and transported in the fermentation tank 500.

The lower part of the upper plate 110 may be sealed and fixed to the bottom of the fermentation tank 500 to prevent air in the air supply pipe 100 from leaking out of the air supply pipe.

The top plate 110 is fixed to the bottom of the fermentation tank 500 to prevent the air in the air supply pipe 100 from leaking out of the air supply pipe 100, and the top plate 110 and the fermentation tank 500 are sealed. can

The lower plate 130 is detachably coupled to the lower part of the upper plate 110 and forms an air passage between the upper plate 110 and the lower plate 130 .

Specifically, the upper plate 110 and the lower plate 130 may be spaced apart from each other so that a passage 141 for air supplied as a shaft may be formed therebetween, and respective lower parts may be coupled to each other.

For example, the shape of the cross section of the upper plate 110 and the lower plate 130 is any one of a half circle, a half ellipse, and a polygon, respectively, and the lower parts of the upper plate 110 and the lower plate 130 may be coupled to each other.

For example, the shape of the cross section of the upper plate 110 is any one of a half circle, half ellipse, and polygonal shape, and the lower plate 130 is composed of the first lower plate 131 and the second lower plate 133, and the upper plate ( 110) may be coupled to the lower portion of the second lower plate 133.

In this case, the first lower plate 131 has a cross-sectional shape of any one of a half circle, half ellipse, and polygonal shape, and the second lower plate 133 extends from the lower part of the first lower plate and is coupled to the lower part of the upper plate 110. can do.

The lower plate 130 may have a preset thickness. For example, the preset thickness of the lower plate 130 may be the thickness of a pipe cleaning tool inserted into the air supply pipe 100 . In this case, when sediment accumulates inside the air supply pipe 100 and is clogged, the lower plate 130 can be pulled out and separated from the upper plate 110, and then the pipe cleaning tool can be easily inserted.

The lower plate 130 may be moved horizontally with the bottom surface of the fermentation tank 500.

Specifically, the lower plate 130 may be drawn out and separated from the upper plate 110 fixed to the bottom of the fermentation tank 500 while moving horizontally with the bottom surface of the fermentation tank 500. This is shown in FIG. 4 .

As described above, since the lower plate can be separated from the air supply pipe in such a way that the lower plate is drawn out, maintenance is easy in the case of clogging due to deposits in the air supply pipe.

More specifically, while air heated from the air supply pipe is discharged to livestock manure, it is introduced into the air supply pipe, and sediment may accumulate or the pipe may be blocked by the introduced sediment. In this case, when the lower plate of the air supply pipe is drawn out and separated, an extra space equal to the volume of the lower plate is created in the air supply pipe. Deposits in the air supply pipe can be easily removed by inserting a pipe cleaner or the like into the created free space.

For example, when the air supply pipe is blocked, the user secures a free space in the air supply pipe by first removing the lower plate of the air supply pipe. Next, deposits accumulated in the air supply pipe may be removed by inserting a pipe cleaner having a brush or a scraper at the end of a round stick or a screw formed into the pipe and then rotating or reciprocating. Conventionally, when sediments accumulated in the air supply pipe are not easily inserted into the air supply pipe, there is a problem in that it is not easy to remove the sediments inside the pipe.

The hot water circulation pipe 300 is accommodated inside the air supply pipe 100 and has a passage through which hot water is circulated.

The hot water circulation pipe 300 is a pipe having a passage in which hot water circulates.

The hot water circulation pipe 300 may be a pipe in the form of a cylindrical pipe.

The hot water circulating through the passage inside the hot water circulation pipe 300 may be heated hot water supplied from the hot water pump.

The hot water pump may supply hot water generated from the hot water boiler to the inner passage of the hot water circulation pipe 300 .

Hot water may heat air in the air supply pipe 100 while passing through the passage inside the hot water circulation pipe 300 .

The temperature of the hot water in the hot water circulation pipe 300 may be a temperature capable of warming the air in the air supply pipe 100 to an appropriate temperature.

The hot water circulation pipe 300 is accommodated inside the air supply pipe 100.

Specifically, the hot water circulation pipe 300 may be accommodated in the accommodation space of the air supply pipe 100 formed by the cross-sectional shape of the lower plate of the air supply pipe 100 and extend in the longitudinal direction of the air supply pipe 100.

A part or all of the hot water circulation pipe 300 may be accommodated in the accommodation space of the air supply pipe 100 . In this case, the accommodation space of the air supply pipe 100 may be formed in a form surrounding the hot water circulation pipe 300 . For example, the accommodating space formed by the lower plate of the air supply pipe 100 may be formed to surround the outer surface of the hot water circulation pipe 300 with a semicircle or more of its cross section.

The hot water circulation pipe 300 may be accommodated in close contact with the accommodation space of the air supply pipe 100 or may be accommodated at a predetermined distance apart. In this case, the greater the contact area between the outer surface of the hot water circulation pipe 300 and the accommodation space of the air supply pipe 100, the higher the efficiency of warming the air in the air supply pipe 100 by the hot water in the hot water circulation pipe 300. In addition, as the distance between the outer surface of the hot water circulation pipe 300 and the outer surface of the lower plate 130 of the air supply pipe 100 is minimized, the efficiency of heating the air in the air supply pipe 100 by the hot water in the hot water circulation pipe 300 increases. can rise

The hot water may heat livestock meal by heating the bottom of the fermentation tank 500 in an Ondol method while passing through the passage inside the hot water circulation pipe 300. In this case, the livestock powder can be heated from below.

The ondol system heats the room by passing the fire under the room. While the method of raising the indoor temperature by heating the air using gas or electricity heats the room from the top, the ondol method heats the room from the bottom in contact with the floor. You can heat the axis.

As described above, by accommodating the hot water circulation pipe inside the air supply pipe to heat the air in the air supply pipe, and supplying the heated air to the livestock meal to heat the livestock meal, it is possible to minimize the decrease in fermentation efficiency of livestock meal at low temperatures. .

In addition, thermal efficiency can be increased by heating the fermenter and the loaded livestock manure in an ondol method using hot water passing through a passage inside a hot water circulation pipe installed at the bottom of the fermenter. In the case of the ondol system, there is an advantage in that the lower part in contact with the floor is heated. Conventionally, a method of heating the entire compost fermentation apparatus with high-temperature air using a blower, etc. was used to warm the compost at low temperatures, such as in winter. There was a problem of poor thermal efficiency.

Meanwhile, in FIG. 2 , the hot water circulation pipe 300 is illustrated as being installed only on the bottom of the fermentation tank 500, but the hot water circulation pipe 300 may be additionally installed inside the sidewall of the fermentation tank 500. When the hot water circulation pipe 300 is accommodated in the sidewall of the fermentation tank 500, the sidewall of the fermentation tank 500 may be heated. Through this, it is possible to solve the conventional problem in which the temperature of the sidewall of the fermentation tank is low and the livestock powder loaded on both sides of the fermentation tank is hardened and the stirring efficiency is lowered.

In the compost fermentation device according to an embodiment of the present invention, the sediment in the air supply pipe can be easily removed using the free space created by separating the lower plate from the air supply pipe in a manner in which the lower plate is drawn out, so maintenance of the air supply pipe is easy. . In addition, due to this, it is possible to reduce the cost, manpower and time required for conventional maintenance.

6 is a cross-sectional view of the air supply pipe and the hot water circulation pipe of FIG. 2 taken along line BB′.

2 and 6, a plurality of air supply pipes 100 are disposed spaced apart from each other at the bottom of the fermenter 300, and one hot water circulation pipe 300 may pass through the plurality of air supply pipes. .

A plurality of air supply pipes 100 may be disposed at the bottom of the fermentation tank 300 and spaced apart from each other.

A plurality of air supply pipes 100 may be arranged spaced apart from each other at equal intervals at the bottom of the fermentation tank 300, but are not limited thereto, and may be arranged in various forms as needed.

One hot water circulation pipe 300 may extend through all of the accommodating spaces formed inside the plurality of air supply pipes 500 .

The hot water circulation pipe 300 may be bent downward at the end of each air supply pipe 500 to facilitate separation of the lower plate 130 from the upper plate 110 of the air supply pipe 500 .

For example, the air supply pipe 500 may include a first air supply pipe 101 and a second air supply pipe 103 disposed adjacently and spaced apart from each other, and one hot water circulation pipe 300 may include a first air supply pipe 101 and a second air supply pipe 103. It may pass through the inside of the supply pipe 101 and the second air supply pipe 103 .

Specifically, first, the hot water circulation pipe 300 may be accommodated in an accommodation space inside the first air supply pipe 101 formed by the shape of the lower plate 130 of the first air supply pipe 101 .

Next, the hot water circulation pipe 300 may extend to an end of the first air supply pipe 101 along the longitudinal direction of the first air supply pipe 101 and pass through the first air supply pipe 101 .

Next, the hot water circulation pipe 300 may be refracted and extended downward from the end of the first air supply pipe 101 . At this time, the hot water circulation pipe 300 may extend downward to a depth lower than the lower portions of the first and second air supply pipes 101 and 103 . That is, when the hot water circulation pipe 300 is later bent in the direction of the second air circulation pipe 103, the height of the upper surface of the hot water circulation pipe 300 is higher than the lower surface of the first and second air supply pipes 101 and 103. It may extend downward to a depth lower than the height. In this case, when the lower plate 130 of the first air supply pipe 101 is withdrawn, it is possible to prevent the lower plate 130 from interfering with the hot water circulation pipe 300 .

Next, the hot water circulation pipe 300 may extend to the lower end of the second air supply pipe 103 .

Next, the hot water circulation pipe 300 may be extended and inserted into the accommodation space inside the second air supply pipe 103 formed by the shape of the lower plate 130 of the second air supply pipe 103 .

Next, the hot water circulation pipe 300 may extend to the other end of the second air supply pipe 103 along the length direction of the second air supply pipe 103 and pass through the second air supply pipe 103 .

Thereafter, the hot water circulation pipe 300 may extend and pass through another air supply pipe 100 adjacent to the second air supply pipe 103 in the same manner as described above.

As described above, since the hot water circulation pipe is bent downward at the end of each air supply pipe and connected, the problem that the lower plate is caught in the hot water circulation pipe when the lower plate is drawn out and separated from the upper plate of the air supply pipe can be solved.

7 is a cross-sectional view of the air supply pipe and the hot water circulation pipe of FIG. 2 and the air injection nozzle inserted into the air supply pipe taken along line C-C′.

Referring to FIG. 7 , an air injection nozzle 150 may be inserted into the air discharge hole 111 formed in the air supply pipe 100 .

A plurality of air discharge holes 111 communicating the inside and outside of the air supply pipe 100 may be formed through the upper plate 110 of the air supply pipe 100 .

The air discharge hole 111 may be an opening through which air introduced into the passage 141 of the air supply pipe 100 is discharged as shaft powder.

The air discharge hole 111 may be opened in the axial direction loaded on the top plate 110 .

The air supply pipe 100 may include an air injection nozzle 150 inserted into the air discharge hole 111 .

The air discharge hole 111 can supply air only in the direction of the axis loaded on the top, and thus the air supply efficiency is low. When a separate air injection nozzle 150 is connected to the air discharge hole 111, the air supply direction and the air supply position can be adjusted, so that the user can supply air in an appropriate direction and position.

Specifically, the air injection nozzle 150 may be inserted into the air discharge hole 111 .

The air injection nozzle 150 is connected to the air discharge hole 111 to control the discharge direction of air discharged as shaft powder through the air discharge hole 111 .

The air injection nozzle 150 may be formed of a material having elasticity such as rubber so as to be easily inserted into the air discharge hole 111 .

After the air injection nozzle 150 is inserted into the air discharge hole 111, a fixing protrusion may be formed outward at an end into which the air injection nozzle 150 is inserted so as not to fall out easily by an external force.

An air injection passage 151 may be formed in the air injection nozzle 150 .

The air injection passage 151 is an air passage formed inside the air injection nozzle 150, and the air inside the air supply pipe 100 can be discharged as axis powder through the air injection passage 151.

At least two air injection passages 151 may be formed in one air injection nozzle 150 to inject air toward the axis powder so as to uniformly supply air to the axis content.

At this time, the direction of each air injection passage 151 may be formed in different directions. In this case, the air supplied through the air supply pipe 100 can be evenly sprayed to the livestock in the fermenter 1 using the plurality of air spray passages 151 .

Each air injection passage 151 formed in the air injection nozzle 150 may be formed to inject air downward.

Specifically, the air injection passage 151 may be formed to inject air in a direction lower than the position of the end of the air injection passage 151 .

In this case, it is possible to minimize the inflow of livestock powder into the air supply pipe 100 by the shape of the air injection passage 151 formed downward. On the other hand, when the air injection passage 151 is formed upward, livestock content loaded on the upper part of the air supply pipe 100 can be easily introduced into the air supply pipe 100 .

8 is a view for explaining an air supply pipe according to an embodiment of the present invention.

Referring to FIG. 8 , the air injection nozzle 150 may have one air injection passage 151 capable of injecting air downward and perpendicular to the ground.
