The present invention relates to a food waste liquid dissipation treatment device that can reduce the economic and environmental damage and waste of budget shown in the food waste disposal process.

Food waste (Food Waste), a representative organic food waste, has emerged as the biggest environmental pollution problem in the 21st century. In Korea, the landfilling method has been used for decades, but seasonings, broths, and contaminants with protein, carbohydrates, fats, and fiber, and four cuts, still have an obstacle to administration and industry, and have no standardization technology that is a problem for national affairs. to be.

Recognizing this, the government has already banned landfills of food waste on January 1, 2005, and it is mandatory for households to separate and discharge food wastes, including more than 125 square meters of restaurants or catering groups of 100 or more, 3000 Large-scale stores of more than ㎡, ie, agricultural and fisheries centers, are required to reduce food waste by themselves and enact laws that impose up to three years imprisonment or fines of up to 20 million won for violations. Article 9 2).

Food waste generated 1000 tons per day is a waste of resources worth 14 trillion won per year, which is a huge waste of two more airports in Incheon, and the government has made resources for food waste, compost or feed. We are doing our best to recycle them, but we have yet to produce other wastes due to immaturity of treatment technology and equipment, so we can't find a clear solution. There was no big problem.

So far, food waste disposal methods can be largely divided into 'resourceization methods' and' exhausters' self-disposal methods'. It is a preferred method. However, since the recycling method of food waste requires huge facilities and costs, it cannot be installed in general homes or catering establishments, so it is transported to the treatment plant where the equipment is installed and disposed of, and food waste having 80 to 85% moisture content is disposed of. Easily decayed, the odor, sewage and salinity during transport revealed the limit of composting, and due to the lack of technology, the government is trying to improve by investing a lot of money, but there is no clear solution. ,

Moreover, wastewater treatment of over 100,000ppm that is inevitably generated in the treatment facility is not allowed to enter the terminal treatment plant.In case of self-treatment at the facility, so far, due to the huge land, facility investment, treatment cost, environmental pollution, etc. However, the crisis of litter crisis is on the horizon as it exposes the disposal limits of treatment facilities by enforcing and banning legislation and gradual strengthening of the OECD member countries.

In this regard, the government has enacted the 'discharge self-disposal method' among the food waste disposal methods. During self-treatment of food waste 1) Grinding / aka disposer (unusable legislation), 2) Drying (energy cost, environmental pollution, secondary disposal discomfort, drying waste), 3) grinding dehydration ( Energy cost, environmental pollution, secondary treatment inconvenient, dry water may cause loss due to mixed waste of general waste, environmental pollution by desorption deterioration, bad effect of sewage by high concentration wastewater discharge, 4) crushing compression (energy cost, environmental pollution) , Secondary treatment incompatibilities, fear of loss due to mixed waste of general wastes, environmental pollution by denatured desorption, adverse effect of sewage by high concentration wastewater discharge, 5) enzymatic destruction (environmental pollution, large size of equipment due to processing time limit, 6) Liquid extinction (prevention of decay due to shortening of processing time, reduction of energy cost due to heat generation when decomposing organic matter of microorganism, beneficial effect of sewage due to the role of microorganism in discharged water) In particular, the self-extinguishing liquid treatment method is attracting extraordinary attention from research institutes and the market with new technologies. In accordance with the pink prediction that it will be established, mass-producing equipment is produced by business owners who have been founded like a bamboo shoot without any clear technical solution, fooling consumers and losing the trust of the industry, bringing about the crisis of abolishing the entire industry. The situation is confusing.

The conventional food waste extinguishing treatment device has been guilty of circulating the food waste treatment without developing it based on simple mechanical concepts and general theories, and without sufficient verification in the market. In particular, the stirring blade is shaped like a simple spatula without any special functions, so the organic matter with round shape such as green onions, radishes, cabbage leaves, etc. before cooking is hardly processed, but is also wound up and rolled. There was a problem of inducing odor due to the overload and decay of the device, and it showed the limitation of processing time and processing capacity of food waste due to the death and dormancy of microorganisms that were not considered due to the survival environment of microorganisms. It is a problem that cannot be used smoothly because there are many defects such as stopping food wastes due to overloading. Also, when decomposing food waste using microorganisms, it is produced without properly understanding the characteristics and proper environment of microorganisms. Because of the lack of microbial activity due to the devices, it is not effectively broken down. The membrane is formed by the mucus composed of sugars, peptins, etc., which are derived from the decomposition, and thus, the inflow of oxygen is blocked and the microorganisms are killed in a short period of time. And fats such as beef fat (beef oil, 36 ~ 50 ℃) are operated at a temperature lower than the temperature at which it coagulates, so that it coagulates in the agitator tank and the outlet to prevent the decomposition of other food waste, kill microorganisms and inhibit smooth discharge. In winter, when the temperature dropped, there was a problem that became worse.

In order to solve this problem, recently disclosed a breakthrough apparatus and method in which a large number of improvements in Korea Patent Registration No. 722714 and Korean Patent Registration No. 835168.

However, various problems to be improved have also been found in the above-described inventions.

First, the problem of overloading of the driving motor during the agitation due to the fibrous garbage in the center of the stirring blade formed by the left and right symmetry, and also when starting to stir heavy wood chips containing a large amount of food waste and water The problem that the drive motor is overloaded, also the user does not recognize the failure at all when a failure occurs, and also the problem that is not easy to repair in the field at the time of failure, and also the problem that noise occurs when operating the motor drive And also, the bearing is easily worn due to the outflow of salinity through the portion that penetrates the stirring shaft and both ends of the stirring tank, and the period of time is prolonged because the culture of the microorganism is not smoothed when the device of the present invention is used for a long time. There was a problem in that the microorganisms should be periodically reintroduced.

In addition, a large amount of oxygen is consumed when the food waste decomposition activity of the microorganisms in the stirring tank, the microorganisms are not killed or cultured well due to the lack of oxygen supply in the stirring tank close to the closed state due to the smell of food waste There was a problem.

In addition, in the case of the wood chips in which not only oxygen but also microorganisms inhabit the agitation tank, various types of wood chips, such as cedar and pine, have been cultivated. For this reason, there was a problem in selecting wood suitable for microbial habitat.

The present invention is devised to solve the conventional problems as described above, it can be applied to aerobic microorganisms active at 35 to 65 ℃ during food waste treatment using microorganisms, 1) the stirring blade attached to the center of the stirring tank when stirring Open the part to prevent overload caused by the seizure of fibrous garbage, 2) Intermittently drive the motor at start-up to prevent overload, 3) Add alarm function to induce A / S immediately in case of failure, 4 ) The motor's forward / reverse rotation function makes it easy to solve when jammed. 5) The BLDC motor is used to reduce noise dramatically, improving the constant velocity efficiency when operating at quiet and low speed. By inserting dena and welding from outside the agitator tank, it prevents bearing wear due to salt, and 7) provides an optimal environment for microbial activity and culture. By providing functions, stable use, and user convenience for the food, it maximizes the self-cleaning effect of the natural world, effectively disintegrates and destroys food waste into inorganic matters in a shorter time, and reduces it to the natural world. The purpose is to provide a food waste liquid extinction treatment device that can reduce the economic and environmental damage shown and waste of budget.

It is a very useful invention that can provide a waste liquid waste treatment apparatus.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, Figure 2 is a front view showing the internal configuration of the food waste treatment apparatus to which the present invention is applied, Figure 3 is a perspective view showing a stirring blade of the food waste treatment apparatus to which the present invention is applied, Figures 4 and 5 apply the present invention Partial enlarged view showing bearing wear preventing means of food waste treatment device.

The present invention is to provide an improved food waste treatment apparatus 1, as shown in FIG.

First, the conventional stirring blade 21 pushes the food waste 3 and the wood chips 2 outward from the outside with respect to the stirring shaft 20 and the food waste inside the center with the stirring shaft 20 ( 3) and wood chips 2 are designed to be pushed to the center side. This is because the stirring tank 10 and the bearing 35 are installed at both ends of the stirring shaft 20, so that a very large overload occurs when the food waste 3 and the wood chips 2 are driven at both ends, so that stirring becomes difficult. Because.

Therefore, the stirring blade 21 is also formed symmetrically and the stirring blade 21 formed in this way was to meet at the center.

As shown in FIG. 1, when the agitating blades 21 in the center meet at both sides, there is a gap, and when the fibrous garbage is caught, very large friction is generated with the agitator tank 10, and the driving motor is overloaded. As a result of the frequent failures, this problem was solved by designing the stirring blades 21 to be spaced between the stirring blades 21 on both sides of the car in order to improve the symmetry while not causing gaps.

In addition, the driving motor 40 may be improved by employing a brushless direct current (BLDC) motor.

The BLDC motor is widely applied to the automobile industry, aerospace industry, medical equipment, factory automation, experimental training facilities, as well as general office supplies and household equipment, and as the name suggests, the BLDC motor is used for commutation. Electronically rectified by the control circuit without using a brush. BLDC motor has many advantages as below compared to brushed DC motor and induction motor.

Better speed-to-torque characteristics, higher dynamic response, higher efficiency, longer operating life, lower noise, higher speed range, and greater torque for the same motor size, making it useful for space and weight-constrained applications. .

By adopting the BLDC motor with the above advantages, the motor is intermittently driven at 0.5 second intervals at start-up to reduce the large frictional force generated at start-up to prevent overloading, and to prevent the normal rotation and By repeating the reverse rotation, it is easy for the user or the A / S staff to immediately solve the jam, and the noise of the driving motor is reduced to provide a comfortable working environment.

In addition, in order to solve the problem that a failure occurs due to the wear and corrosion of the bearing 35 provided on both ends of the stirring shaft 20 due to salt due to the nature of food waste, the stirring shaft hole 11 of the stirring tank 10 outside The bearing flange 33 for holding the lidena 31 in close contact with the lidena flange 32 accommodating the lidena 31 to the outer surface of the stirring vessel 10 and accommodating the bearing 35 on the other side thereof. It is a technical feature of the structure to prevent the leakage of salt by screwing together with the lid 36 to seal the outer surface of the bearing flange 33 after close contact with the lidena flange 32.

In addition, at this time, the stirring shaft 20, the driving shaft 22 and the support shaft 23 are each shaft-connected by welding and screwing the coupling to facilitate separation of the stirring shaft 20.

In addition, the conventional food waste treatment method has a problem that the microorganisms are killed in the short-term or long-term when processing food, and after studying the food waste treatment method for a long time, by changing the treatment method to create an environment in which microorganisms are not killed and cultured by themselves. I can do it.

Hereinafter, the present invention will be described in detail through preferred embodiments. However, the present embodiments should be understood to explain the present invention in a better understanding, and should not be construed as limiting the present invention thereto.

First, the food waste treatment apparatus 1 of the present invention is manufactured so that the stirring blade 21 is separated from the left and right in the middle, as shown in FIGS. By changing the structure in this way it is possible to prevent the jam of the fiber waste in the center.

In addition, the drive motor 40 of the present invention employs a brushless direct current (BLDC) motor. The BLDC motor is small in size and has a large torque, so if the motor is intermittently driven at 0.5 second intervals at start-up, the large friction force generated at start-up can be reduced to prevent overload, and the reverse and reverse rotation can be easily converted to fiber waste. In the event of a fault caused by a jam, such as forward and reverse rotation, the user can solve the problem himself or A / S staff can solve the problem right away on the site, and the noise of the driving motor can be reduced to provide a pleasant working environment. do.

In addition, as shown in FIGS. 4 to 5, the bearing shaft for preventing corrosion and wear of the bearing due to salinity of food waste in a portion where the drive shaft 22 and the support shaft 23 are coupled to the stirring vessel 10. Preventing means 30 is installed.

The bearing wear preventing means 30 is a lid 36 for sealing the lidena flange 32 for accommodating the lidena 31 and the bearing flange 33 for accommodating the bearing 35 and the other side of the bearing flange 33. It consists of

The lidena flange 32 is in close contact with the outer surface of the stirring tank 10 is welded to the disc shape of the predetermined thickness is installed so that the lidena seating hole 321 is formed in the center concentric to the stirring shaft hole (11) Form.

In addition, the lidena 31 is seated in the lidena seating hole 321 of the lidena flange 32, but a predetermined through-hole 311 formed in the center is formed to be in close contact with the drive shaft 22 or the support shaft 23 It is formed in a ring-shaped thick.

In addition, the bearing flange 33 has a through-hole is formed so as to be inserted into a plurality of male screw portion 322 is formed to protrude in parallel with the stirring axis direction from the predetermined position of the lidena flange 32 and the bearing seating hole in the center 331 is formed to form a plate of a predetermined thickness in close contact with the lidena flange 32 so as to be concentric with the stirring shaft hole (11).

In addition, the bearing 35 is seated in the bearing seating hole 331 of the bearing flange 33 is formed to have an inner diameter smaller in diameter than the through hole 311 of the lidena 31 in the center. Since the bearing 35 is a conventional bearing 35, detailed structural description thereof will be omitted.

In addition, the cover 36 has the same outer diameter as the bearing flange 33 so as to seal the outer surface of the bearing flange 33 and protrudes from the lidena flange 32 and extends through the bearing flange 33. A through hole 322 is formed to be fastened to the nut 37 from the outside, and in the case of the drive shaft side, the through hole 322 is formed in a plate shape having a predetermined thickness in which a through hole through the drive shaft 22 is also formed.

Referring to the process of coupling the bearing wear preventing means 30 formed as described above with the stirring shaft 20 is as follows.

First, the lidena flange 32 is welded to and fixed to the outer side surfaces of both stirring shaft holes 11 of the stirring tank 10.

Next, the lidena flange is inserted into the lidena flange 32 to be seated.

Next, the bearing flange 33 is in close contact with the outer surface of the lidena flange 32 is inserted into the male screw portion 322 extending outward from the lidena flange 32 to be in close contact with the bearing 35 is inserted.

Next, the cover 36 is in close contact with the outer surface of the bearing flange 33, but inserted into the male screw portion 322 extended from the lidena flange 32 together with the bearing flange 33 and fastened with a nut 37 Fix it.

Next, the support shaft 23 and the drive shaft 22 are inserted from the inside to the outside in both stirring shaft holes 11 of the stirring vessel 10.

Next, the stirring shaft 20 integrated with the stirring blade 21 is inserted into the stirring tank 10 and the stirring shaft coupling 202 and the support shaft coupling 231 and the driving shaft couple welded at both ends. By screwing the ring 221, the lidena 31 is in close contact with the stirring shaft 20 and the stirring tank 10 so that the water with salt inside does not flow out to prevent the wear of the bearing 35. It becomes possible.

In addition, an oxygen inlet hole 71 is formed on one side of the stirring tank 10, and an air outlet hole 72 is formed on the other side thereof, while an oxygen generator 73 is connected to the oxygen inlet hole 71. Oxygen supply means 70 is further provided to continuously supply oxygen by supplying oxygen in the process.

Thus, by supplementing the large amount of oxygen consumed in the decomposition of the microorganisms it is possible to prevent the death of the microorganisms due to lack of oxygen to stop the culture.

In addition, the control means 60 is connected to the drive motor 40 is an alarm means for informing the abnormal state through the speaker 51 and the display unit 52 when the overload occurs or abnormally stopped during the driving of the drive motor 40 ( 50).

Conventional constitutions other than the features of the present invention are used as they are and are not technical features of the present invention.

Thereby, the food waste processing apparatus 1 of this invention was completed.

The improved food waste treatment method of the present invention using the food waste treatment apparatus 1 of the present invention manufactured as described above is as follows.

Food waste treatment method using the microorganism of the present invention, as shown in Figure 6, largely wood chip and microorganism input process (S10), microorganism culture process (S20), food waste input process (S30), and food waste decomposition It consists of a process (S40).

First, the wood chip and microorganism input process (S10), the particle size of the range of 4 to 8 mm in the stirring tank 10 is surrounded by a heater heated to a temperature of 25 to 55 ℃ range, which is a temperature at which microorganisms are good for decomposition activity The oak wood chips 2 are added in an amount ranging from 35 to 45% by volume with respect to the agitation tank 10, and an initial step of introducing a liquid microorganism in proportion to the capacity of the agitation tank 10, the present invention provides Due to the optimal environment for the survival and activity of microorganisms, microorganisms, which have been continuously injected once or twice a month, have been greatly improved so that they can be cultivated on their own.

The oak chip was selected as a wood that prevents the killing of microorganisms and is well cultured after many years of research with various wood chips. It was not done.

Next, the microbial culture step (S20), while spraying the hot water 121 in the range of 50 to 60 ℃ periodically in a number of directions using the nozzle 12 from the top stirring blade 21 installed in the center of the stirring tank (10) Mixing and softening and rest are repeated for 8 to 12 hours.

Next, the food waste input step (S30), the food waste (3) to be in the range of 45% by volume or less with respect to the stirring tank 10 through the cover 13 attached to the upper front side of the frame of the stirring tank 10. Process.

Next, the food waste decomposition process (S40), by spraying the hot water 121 in the range of 50 to 60 ℃ periodically in a number of directions using the nozzle 12 from the top while washing the mucus generated by the microorganisms stirring tank (10) Mixing, soft-nitriding, and rest are repeated for 10 to 14 hours by the stirring blade 21 installed in the center of the food waste (3) process.

In addition, the rubber packing 16 is installed inside the cover 13 installed on the upper portion, and the inside of the stirring tank 10 is formed in a sealed type to prevent a specific food smell from leaking to the outside to improve the use environment.

Since the food waste decomposition step (S40) after 5 hours, most of the organic food waste is decomposed and extinguished, and only a small amount of food including a lime component is left, so that other food waste can be re-injected into the food waste input process (S30). Can be circulated.

In addition, the microbial culture step (S20) and food waste decomposition step (S40), the watering and stirring step (S60), stirring step (S70), the first stop and decomposition step (S80) and washing step (S90) and agent It consists of two stop and decomposition process (S100).

The watering and stirring process (S60) is a process of mixing and softening by the stirring blade 30 while spraying hot water 121 using the nozzle 12 from the top within a range of 40 seconds to 4 minutes, the stirring Process (S70) is a process of mixing and softening by the stirring blade 21 without spraying hot water 121 in the range of 5 minutes to 10 minutes, the first pause and decomposition process (S80) is 10 minutes to 20 minutes Stopping operations such as stirring and washing within the range and waiting for the aerobic microorganism to actively cultivate and decompose, the washing step (S90) is the lower portion of the stirring tank 10 in the range of 20 seconds to 40 seconds A process of washing the lower perforated portion 141 of the stirring vessel 10 by using the first and second cleaning nozzles 15a and 15b while simultaneously discharging the liquid containing the mineral falling into the discharge guide 14 along the discharge guide 14. The second pause and decomposition process (S100) is within a range of 20 to 30 minutes A step of stopping the operation, such as a half and three and aerobic microorganisms are actively waiting to the culture and the decomposition activity.

Of these, the first and second rest and decomposition processes (S80) and (S100) are so important that it is not an exaggeration to say that they are the most important of all the processes. Since microorganisms are living organisms, they are stopped during continuous stirring and softening, and extremely limited digestion and decomposition are performed, followed by rest and decomposition processes to treat food waste through full digestion and decomposition.

However, during the treatment of food waste by the digestion and decomposition of such microorganisms, condensation is carried out in the stirring tank 10 while the hot water 121 sprayed and the steam due to the mucus and heat generated during the digestion and decomposition of the microorganisms fill up. Eventually, the food waste 3 and wood chips 2 fall on the mixture to form a mucus layer and a water film. The mucous layer and the water film block the oxygen supplied to the microorganisms, causing the microorganisms to die.

Therefore, the subsequent washing process (S90) to suppress the water film formation and through the second rest and decomposition process (S100) to treat food waste by the digestion and decomposition of the microorganisms again, a series of processes occur very effectively.

Provided from the oxygen generator 73 connected to the oxygen inlet hole 71 through the oxygen inlet hole 71 formed on one side and the air discharge hole 72 formed on the other side throughout the entire process. By continuously supplying oxygen to prevent the deprivation of oxygen necessary for microbial decomposition and cultivation, it is possible to prevent the killing of microorganisms and stopping culture.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

The effects of the present invention that can be expected by the configuration and action as described above are as follows.

Food waste treatment using microorganisms can be applied to aerobic microorganisms that are active at 35 to 65 ℃, 1) during stirring to open the part attached to the stirring blade in the center of the stirring tank to prevent overload caused by the catch of fibrous garbage, 2) To prevent overload by driving the motor intermittently at start-up, 3) to add an alarm function to induce A / S immediately in case of a failure, and 4) the motor's forward / reverse rotation function makes it easy to solve , 5) BLDC motor reduces noise dramatically and improves the constant velocity efficiency when driving at quiet and low speed. 6) Prevents bearing wear caused by salt by making bearing case and inserting leader to weld outside the stirring tank. And 7) by providing an optimal environment for microbial activity and cultivation to provide early processing, stable use and user convenience. Food technology that can reduce the economic and environmental damage and waste of budget that has been shown in the food waste processing process up to now by maximizing the action to effectively disintegrate and destroy food waste into inorganic matter in a shorter time. It is a very useful invention that can provide a waste liquid waste treatment apparatus and a method thereof.
