Description

High-speed fermenter for drying organic matter of food waste, by-products and livestock manure

The present invention relates to a high-speed fermentor capable of fermenting organic matter at high speed.

In general, food waste or various by-products may be generated in homes, restaurants, etc., and if the food waste or by-products are not properly treated, the environment may be polluted.

In addition, livestock manure is inevitably produced, and if livestock manure is not properly treated and discharged, it can pollute the environment.

The food waste, by-products, and livestock manure described above are organic matter. These organic matter can be fermented using a high-speed fermentor, and the fermented organic matter can be a fertilizer that can supply nutrients to sheep.

A conventionally known high-speed fermentor has a configuration in which a mixer blade is placed inside a fermentation tank and the mixer blade is rotated.

When organic matter is put into the fermentation tank and air is blown, the organic matter is fermented. In addition, operating the mixer blade can increase the fermentation rate by mixing the organic matter.

On the other hand, the organic matter has a lower water content during the fermentation process, and has a watery property at the beginning of fermentation, but a high density property at the end of fermentation.

That is, the high-speed fermenter rotates the mixer blade to increase the fermentation rate. If the density of the organic material is high, resistance is generated in rotating the mixer blade, and when the resistance is high, the mixer blade breaks, etc. there is.

Alternatively, a hydraulic system may be used to rotate the mixer blades. The hydraulic system includes a hydraulic pump that generates hydraulic pressure, a hydraulic line that transmits hydraulic pressure, and an intake cylinder that performs expansion and contraction operations.

The current situation is that the hydraulic system is designed in consideration of the operating cost, and for this reason, the high-speed fermentor must be operated within the range of the processing capacity of the hydraulic system. A heavy load may act on the hydraulic system, and the load may exceed or exceed the processing capacity of the hydraulic system.

On the other hand, looking at the operation process of the high-speed fermenter, the manager repeats the process of discharging organic matter from the fermentation tank and putting new organic matter into the fermentation tank every day.

During the manager's working hours, if there is a problem with the hydraulic system, an alarm sounds, and the manager can listen to the alarm and solve the problem, and the fermentation can continue.

However, when the manager is away or not working hours, the problem cannot be resolved, the problem state may continue to be neglected, fermentation may not proceed properly, and the subsequent fermentation schedule may be disrupted.

In addition, the fermentation tank 10 is supported by the frame 14, whereby the weight of the organic matter put into the fermentation tank 10 can act as a pressure on the frame 14.

The drive shaft 20 is disposed at the bottom of the fermentation tank 10, and as shown in FIG. 1, it may be disposed vertically through the bottom of the fermentation tank 10.

As shown in FIG. 1, the holoshaft 30 is disposed inside the fermentation tank 10 and is assembled to the drive shaft 20.

The high-temperature, high-pressure air is sprayed onto the organic matter to promote fermentation of the organic matter.

The rotary unit 50 may be installed on the frame 14 and rotates the drive shaft 20 hydraulically.

In more detail, the rotary unit 50 includes an actuator 52 that operates using hydraulic pressure, a hydraulic line that allows the hydraulic oil to move, a hydraulic pump that creates pressure in the hydraulic oil, and recovers the hydraulic oil to the hydraulic tank when an abnormally high pressure is detected. It can be configured to include a safety valve that is opened to

The actuator 52 may pull or push the rod 54 according to the direction in which hydraulic pressure is supplied.

A swing plate 60 is connected to the end of the rod 54, and the swing plate 60 rotates around the drive shaft 20 in an angular range.

That is, when the actuator 52 expands, the rod 54 pushes the swing plate 60, and when the actuator 52 contracts, the rod 54 pulls the swing plate 60.

A pusher unit 70 may be installed on the swing plate 60 . The pusher unit 70 is assembled so that the first block 74 can rotate around the first shaft 72 . In addition, a first spring 76 is installed in the first block 74, and the first spring 76 acts as a restoring force so that the first block 74 moves toward the drive shaft 20.

In the gear 80, a first inclined surface 82 and a second inclined surface 84 may be repeatedly formed, and a second socket 86 may be formed in the center. The first inclined surface 82 may be formed with a steep slope with respect to the tangent to the pitch circle of the gear 80, and the second inclined surface 84 may be formed with a gentle slope with respect to the tangent to the pitch circle of the gear 80.

As shown in FIG. 4 , the first block 74 contacts the first inclined surface 82 on its front side and the second inclined surface 84 on its side surface.

Then, as shown in FIG. 5 , when the actuator 52 extends, the front side pushes the first inclined surface 82 , whereby the gear 80 rotates and the drive shaft 20 rotates.

Then, as shown in FIG. 6, when the actuator 52 contracts, the front surface moves away from the first inclined surface 82, and the side surface comes into contact with the second inclined surface 84 and moves away from the gear 80.

Then, as shown in FIG. 4, when the swing plate 60 returns to the initial position, the first spring 76 contacts the other first inclined surface 82 of the gear 80 with the front surface of the first block 74. A restoring force is applied to the first block 74 so as to

The second plug 24 and the second socket 86 may be formed in a polygonal shape, whereby the drive shaft 20 and the gear 80 may be assembled so that they do not run idle.

That is, as the actuator 52 repeats an expansion operation and a contraction operation, the gear 80 repeats an angular rotation and then stops.

The gear 80 may have 22 gear teeth, and one gear tooth may be moved each time the actuator 52 repeats an expansion operation and a contraction operation once. The mixer blade 44 may rotate at a rotational speed of one rotation per approximately 1 hour 6 minutes. The actuator 52 may be set to operate three times in 15 minutes for expansion and contraction.

The amount of organic matter discharged is approximately 0.1 m 3 per 3 minutes, and if the hydraulic oil pressure is not lowered by discharging for 3 minutes, it can be controlled to discharge for 3 more minutes. When the oil pressure is lowered, the discharge can be stopped and the agitation action can continue.

The discharge of organic matter can be 2 m per hour, and the agitation action can continue during discharge.

The high-speed fermentor according to an embodiment of the present invention may include a discharge conveyor 100. The discharge conveyor 100 may include a screw conveyor 110 and a belt conveyor 130.

A screw conveyor 110 may be disposed below the fermentation tank 10 and transport organic matter discharged from the outlet 12 .

The belt conveyor 130 transports the organic matter transported on the screw conveyor 110 to a more distant place.

The screw conveyor 110 will be described in more detail with reference to FIG. 3 .

The screw conveyor 110 may include a housing 114, a screw 116, a door 122, and a door actuator 124, and as shown in FIG. 2, the number of outlets 12 and corresponding It can be configured in plurality by being installed in a position to do.

The housing 114 may be installed in the lower part of the fermentation tank 10, and the input part 118 is disposed to communicate with the outlet 12, and the discharge part 120 on the opposite side of the input part 118 is formed

The screw 116 has a spiral wing and is disposed in the housing 114 and can be operated by the motor 112 . That is, when the motor 112 operates, the screw 116 rotates to transport the organic material from the input unit 118 to the outlet 12.

In addition, the motor 112 can rotate in reverse, and in this way, the organic matter in the housing 114 can be transported from the outlet 12 side to the inlet 118 side. The reverse rotation operation of the motor 112 can be operated according to the manager's will, and can be automatically operated according to the control program of the high-speed fermentor.

For example, the motor 112 may operate while alternating forward rotation and reverse rotation, and may attempt reverse rotation when resistance increases during forward rotation operation.

A door 122 is installed on the discharge part 120 to open and close the discharge part 120 . The door 122 may advance and retreat in a direction crossing the discharge unit 120, close the discharge unit 120 in a forward position, and open the discharge unit 120 in a retracted position.

The door actuator 124 may be installed in the housing 114 or the frame 14 and may expand or contract the opening/closing rod 126 .

By connecting the door 122 to the opening/closing rod 126 , the door actuator 124 operates to open and close the door 122 .

The motor 112 and the door actuator 124 may operate when the hydraulic pressure formed in the rotary unit 50 reaches a set pressure value.

For example, in the high-speed fermenter according to the embodiment of the present invention, the set pressure value can be set to 210 bar, and when the hydraulic oil pressure in the hydraulic circuit of the rotary unit 50 reaches 210 bar, the door 122 is opened and the screw conveyor is opened. 110 may be operated to discharge organic matter.

For another example, in the high-speed fermentor according to an embodiment of the present invention, the set pressure value can be set to 210 bar, a specific time and a specific number of times can be set, for example, the hydraulic oil pressure in the hydraulic circuit of the rotary unit 50 When 210 bar is reached twice within 10 minutes, the door 122 is opened and the screw conveyor 110 operates to discharge the organic matter.

Therefore, the high-speed fermentor according to the embodiment of the present invention detects the load generated when the mixer blade 44 rotates in real time, and discharges the organic matter when the load value reaches the set value, thereby discharging the inside of the fermentation tank. The amount of organic matter can be reduced, the load according to the operation of the mixer blade can be maintained below the set value, and the fermentation of organic matter can be stably continued.

The load value can be understood as hydraulic oil pressure formed in the hydraulic circuit of the rotary unit 50. That is, the resistance formed when the rotary unit 50 operates the mixer blade 44 can be understood as hydraulic oil pressure and can be understood as a load value.

On the other hand, as shown in Figs. 4 to 6 on one side of the gear 80, a reverse rotation prevention unit 90 may be installed.

The anti-reverse rotation unit 90 may include a second shaft 92, a second block 94, and a second spring 96.

The second shaft 92 may be installed on one side of the frame 14, and the second block 94 may rotate around the second shaft 92. The second spring 96 may act as a restoring force so that the second block 94 moves toward the gear 80.

The front surface of the second block 94 faces the first inclined surface 82, and the side surface of the second block 94 may slide with the second inclined surface 84.

That is, when the gear 80 rotates counterclockwise as shown in FIG. 5, the front surface of the second block 94 moves away from the first inclined surface 82, and the side surface of the second block 94 moves away from the second block 94. While sliding with the inclined surface 84, the second block 94 is angularly rotated in a direction away from the gear 80.

Then, as shown in FIG. 6, when the gear 80 moves and rotates by one or more gear teeth, the second block 94 may face the first inclined surface 82 due to the restoring force of the second spring 96. .

When the actuator 52 contracts, the swing plate 60 rotates clockwise. At this time, the gear 80 is attracted by the swing plate 60 and may generate a force to rotate clockwise. Since the second block 94 faces the first inclined surface 82, the gear 80 cannot rotate clockwise.

That is, the anti-reverse rotation unit 90 allows the gear 80 to rotate counterclockwise, but prevents it from rotating clockwise.

On the other hand, since the description is made with reference to FIGS. 4 to 6, the rotation of the gear 80 counterclockwise has been described as forward rotation. Depending on the manufacturing situation of the manufacturing facility, the arrangement direction of the actuator 52 and the gear 80 may be changed to the opposite position, and in this case, clockwise rotation of the gear 80 can be understood as forward rotation.

In addition, the motor 112 and the door actuator 124 of the high-speed fermentor according to the embodiment of the present invention may operate when the humidity of the organic material reaches a set humidity value.

As shown in FIG. 1 , a high-speed fermentor according to an embodiment of the present invention may place a humidity sensor 152 inside the fermentation tank 10. More specifically, the humidity sensor 152 may be disposed close to the bottom of the fermentation tank 10, for example, at a height of 30 to 50 cm from the bottom.

As a result, when the humidity is lowered as the organic matter is fermented, the humidity value of the organic matter can be measured more accurately, and it can be an important data for estimating the time of organic matter discharge.

The lower humidity means that the resistance to rotate the scraper blade 42 and the mixer blade 44 to mix the organic matter increases.

Since there are too many variables such as the type of organic matter, weather, season, and surrounding environment, it is difficult to uniformly define the humidity value and build it into a database.

Therefore, the operator can set the humidity value based on experience or accumulated data, and in this way, a higher quality fermentation effect can be expected, and the operation of the rotary unit 50 stops or the scraper blade 42 or the mixer blade ( 44) can be prevented from being damaged.

In addition, the motor 112 and the door actuator 124 of the high-speed fermentor according to the embodiment of the present invention may be operated when the weight change of the organic material reaches a set weight reduction value.

The organic matter may decrease in weight as it goes through the fermentation process, and by discharging the organic matter based on the weight reduction value, the operation of the rotary unit 50 is stopped or the scraper blade 42 or the mixer blade 44 is prevented from being damaged. It can be prevented.

On the other hand, in the high-speed fermenter according to the embodiment of the present invention, as shown in FIG. 1, a plurality of the frames 14 may be provided, and as shown in FIGS. 1 and 7, the weight of each frame 14 is measured. A plurality of weight sensors 140 may be disposed.

The weight reduction value may be calculated by subtracting the average value of the weight values measured by the plurality of weight sensors 140 from the weight value at the start of fermentation.

That is, if the weight reduction value is known, it is possible to estimate how much fermentation has progressed, and thus, the high-speed fermentor according to the embodiment of the present invention can discharge organic matter at an appropriate time.

In addition, the high-speed fermentor according to an embodiment of the present invention may further include a balance plate 142 as shown in FIG. 7 .

As shown in FIG. 1 , the balance plate 142 may be disposed below the plurality of frames 14, and the plurality of weight sensors 140 may be installed below the balance plate 142. there is.

As a result, when the weight of the fermentation tank 10 and the organic matter acts in the direction of gravity, the balance plate 142 balances and transfers a uniform pressure to a plurality of weight sensors 140 so that a certain weight sensor 140 Concentration of the load can be prevented, thereby reducing the weight value error.

On the other hand, as shown in FIG. 1, the temperature sensor 150 may be configured at the top, middle, and bottom of the fermentation tank 10, and the temperature sensor 150 measures the temperature during fermentation from the beginning of fermentation. By continuously measuring , the temperature change value can be measured. The change in the temperature value can be used as a reference when the operator determines when to discharge the organic matter.

The temperature of the organic matter may be somewhat high at the beginning of fermentation, but the temperature may gradually decrease from a specific point in time when fermentation is completed. Based on this temperature change value, the door 122 is opened and the screw conveyor 110 is operated. Thus, organic matter can be discharged.

That is, in the high-speed fermentor according to the embodiment of the present invention, when the hydraulic oil pressure can be maintained below the set pressure value and the humidity value is such that organic matter can be discharged below the set pressure value of the hydraulic oil, the operator calculates the amount of organic matter input and discharged per day. Thus, the automatic discharge time can be set to the optimal state.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art to which the present invention belongs will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. You will be able to.

Therefore, the embodiments described above should be understood as examples and not limitations in all respects, and the scope of the present invention is indicated by the claims to be described later, and all derived from the meaning and scope of the claims and equivalent concepts thereof. Changes or modified forms should be construed as being included within the scope of the present invention.
