Description
Technical Field
The present invention relates to a hot air generating apparatus for generating hot air by heating waste from slaughtered pigs, cattle or the like, and more particularly, to a hot air generating apparatus for generating hot air by using waste animal fat, comprising: a conveying unit such as a conveyor belt or the like; a heating unit for heating the slaughter waste conveyed by the conveying unit; a degreasing unit for compressing slaughter waste heated by the heating unit to thereby generate waste gas grease; a storage unit for storing the waste grease degreased by the degreasing unit; and a hot air generating unit for supplying and burning the waste grease stored in the storage unit to generate hot air, the above units being sequentially connected to each other to degrease and store the waste grease contained in the slaughtered waste, and then supplying the waste grease with fuel and drying the object to be dried using the hot air generated during the burning.
Background
In general, organic pollutants such as sewage sludge, livestock manure, food waste, etc. have a large water content, so that they are difficult to transport and store, and they are easy to rot and generate malodor, and if they are landfilled in a landfill site, they generate a large amount of percolate, so that they pollute rivers and groundwater.
Thus, these sludge-like pollutants are preferably rapidly composted or fed rather than landfilled. For this reason, various treatment methods for composting or forage conversion have been developed, and among them, composting or forage conversion methods using microorganisms are considered as environmental protection methods and are actively used. However, this microorganism treatment method has a long treatment time and drastically decreases treatment efficiency depending on weather, operating conditions, and the like. In addition, it is difficult to handle a large amount of pollutants.
In contrast, a physical treatment method such as drying or evaporation, which evaporates water or oil from contaminants for easy transportation and storage and prevents decay, has the advantages of simple and rapid operation, small-scale operation, etc., but has not been widely used due to the disadvantage of high energy consumption.
However, various technologies for recovering heat energy from waste resources have recently been developed so that heat energy can be obtained at relatively low cost, thereby increasing attention to physical treatment methods such as drying or evaporation. Therefore, a method has been developed in which the microorganism treatment is difficult for livestock manure or the like, or the contamination substances generated in large amounts such as food waste are physically treated before transportation and storage, and the waste after the physical treatment is used as a raw material for mixed feed or destroyed.
Among them, drying is a physical treatment method for evaporating moisture from an object to be dried by using heat energy, and is considered to be a very useful treatment method because of its rapidity and simplicity, and such drying methods generally include a heat conduction drying method and a hot air drying method.
First, the hot air drying method is a method of directly contacting hot air with an object to be dried, and is classified into a direct heating method and an indirect heating method according to the kind of hot air injected.
The direct heating method is a method of diluting combustion gas generated in a combustion device with air and then directly injecting the diluted combustion gas into a drying furnace, and the indirect heating method is a method of injecting combustion gas or the like into a hot air generator or a heat exchanger to form hot air, and then injecting the hot air into the drying furnace.
However, since the carbonized combustion gas of the fuel for the hot air drying method discharges the soot containing the harmful substances into the atmosphere, causing environmental pollution, thus posing serious threat to public health, a hot air generating apparatus using an environmentally friendly alternative fuel is recently being developed to replace the carbonized combustion gas for the hot air drying method fuel as described above.
In addition, with respect to such an apparatus, there have been proposed various proposals in which after heating slaughter waste generated when slaughtering livestock such as cattle or pigs, fat (waste grease) is extracted, and the extracted fat is used as combustion fuel for a hot air generating apparatus to supply hot air.

a screen unit 140 provided at one end of the main body unit 120 so as to penetrate therethrough, for removing waste grease from the transferred slaughter waste; and
a slaughter waste discharge unit 150 provided at one end of the screen unit 140 so as to pass therethrough, and formed with a slaughter by-product discharge port 151 for discharging separated waste grease,
the slaughter waste discharge unit 150, comprising: a taper unit 152 having a cylindrical shape formed by a plurality of rotating plates 152a so as to partially overlap each other, and rotatable at an end of the screen unit 140, and having a diameter smaller toward a tip end; a cover unit 153 disposed outside the taper unit 152; and a compression coil spring 154 having one end connected to the cone unit 152 and the other end connected to an inner wall of the cover unit 153, which is expanded or contracted or restored by a transfer pressure of slaughter waste transferred from the slaughter waste transfer device 130, thereby changing a diameter of the cone unit 152.
As shown in fig. 2, the degreasing unit 100 is configured to supply and store slaughter waste containing waste grease heated by the heating unit 12 to the main body unit 120 through a penetrating unit at a lower end thereof when the slaughter waste is thrown in through an upper side of the hopper unit 110.
Here, the structure of supplying the slaughter waste heated by the heating unit 12 to the hopper unit 110 may be such that when the temperature of the slaughter waste heated by the heating unit 12 rises to a certain temperature, an outlet (not shown) is automatically opened to be moved and supplied to the hopper unit 110, and various conventional techniques may be applied.
A slaughtered waste pulverizing unit 112 is provided at a lower portion of the hopper unit 110, and is advanced and retracted by an air cylinder 111. The slaughter waste pulverizing unit 112 is provided at a front end where slaughter waste is introduced into the main body unit 120, for pulverizing the slaughter waste. The slaughter waste pulverizing unit 112 is provided above an introduction hole in the main body unit 120 for introducing slaughter waste, for pulverizing the slaughter waste in a smaller size, and may be provided with one or more according to the size of the hopper unit 110. The cylinder 111 may be driven hydraulically or pneumatically or electrically, and different operation intervals are set according to the shape of slaughtered waste introduced into the hopper unit 110.
Further, when the compression coil spring 154 is continuously compressed for a predetermined time or longer, the slaughter waste pulverizing unit 112 may be configured to stop the rotation of the screw and advance and retract for a predetermined time or longer.
The end of the slaughtered waste pulverizing unit 112 is formed to be as sharp as a blade, and is inclined downward as shown in the drawing, so that the cut slaughtered waste is easily pushed toward the introduction hole of the main body unit 120.
In the main body unit 120, the driving shaft 132 is rotated by the driving motor 133. Therefore, as described above, when slaughter waste is introduced into the main body unit 120 through the hopper unit 110, the slaughter waste is transferred to the inside of the main body unit 120 through the screw 131 provided at the driving shaft 132.
Slaughter waste moving along the inside of the main body unit 120, while passing through the screen unit 140, is compressed while reaching the cone unit 152 provided at the slaughter waste discharge unit 150. This is because the diameter of the cone unit 152 gradually becomes smaller toward the end thereof, so that the continuously conveyed slaughter waste stays in the cone unit 152 and cannot move forward.
In the screen unit 140, a plurality of degreasing holes h are provided on the entire surface of the screen 140a, and a screen cover 142 forming a waste grease outlet 141 is provided on the outer side thereof.
Accordingly, when slaughter waste is continuously conveyed and moved to the cone unit 152, a pressing force is generated on the slaughter waste by the cone unit 152 (i.e., the compression coil spring is not compressed at the beginning). At this time, the slaughter waste is pressed to separate waste grease, and the separated waste grease flows out through degreasing holes of a screen formed in the screen unit 140, is discharged through the waste grease discharging port 141 provided in the screen cover 142, and is supplied through the supply line 13a and stored in the temporary storage unit 13b.
At this time, when slaughter by-products transferred to the taper unit 152 and removing waste gas grease increase, the compression coil springs 154 pressing the taper unit 152 are compressed by external pressure. That is, as the degreasing slaughter by-product increases, it pushes out the taper unit 152, thereby compressing the compression coil spring 154.
Thus, the taper unit 152 is gradually opened so that slaughter by-products are squeezed out through the end of the taper unit 152 and discharged through the discharge port 151 provided at the cover unit 153 so as to be supplied to the drying unit 14.
As described above, the taper unit 152, which is opened according to the compression degree of the slaughter by-products, is not affected by the amount or density of the slaughter by-products, etc. In addition, when the amount or density of the slaughter by-products transferred is reduced in a state where the compression coil springs 154 are compressed, the compression coil springs 154 restore the elastic force so that the taper units 152 are gradually retracted.
Accordingly, according to the present invention, the slaughter by-products accumulated in the cone unit 152 are automatically opened or retracted according to the size (amount) or density, etc., to separate waste grease, and the slaughter by-products from which the waste grease has been removed are extruded to the discharge port 151 to be supplied to the drying unit 14 for treatment.
Further, as shown in fig. 3, the taper unit 152 provided in the degreasing unit 100 is formed in a hollow conical shape, which is partially overlapped with each other at corners by a plurality of rotating plates 152 a. At this time, the rotating plate 152a is formed in a circular shape protruding upward.
Fig. 5 shows an example in which the rotary plate 152a is formed in a circular shape protruding upward.
However, if a flexible member having elastic force is used for the rotation plate 152a, it may be provided in a plate shape and then bent for use, or may be provided in a cylindrical shape.
As described above, the rotating plate 152a may be provided with the rotating device 160 at an end of the screen unit 140, thereby rotating the rotating plate. The rotating device 160 may be generally provided by means of an existing hinge device or the like, and a detailed description thereof will be omitted herein.
Further, the rotating plate 152a is preferably formed such that a width W1 of one end connected to the screen unit 140 is smaller than a width W2 of the other end. At this time, the taper unit 152 is connected to the connection portion of the screen unit 140 by one end of the plurality of rotation plates 152a having a small width, thereby forming a hollow conical shape (also referred to as a round-through shape), so that the diameter of the connection portion with the screen unit becomes large, and the other ends having a large width overlap each other, thereby making the formed diameter small.
Also, inside the cover unit 153, a partition crease member 155 (also called a bellows) is provided, one end of which is fixed to the inner wall surface of the cover unit 153 and the other end of which is connected to the end of the cone unit 152, for preventing slaughter byproducts pressed out by the end of the cone unit 152 from flowing back into the compression coil spring 154 to avoid being entangled with each other.
Here, the number of the compression coil springs 154 may be adjusted according to the characteristics of slaughter waste (by-products) to be treated. The greater the number of the compression coil springs 154, the greater the pressing force against slaughter waste, so that although the waste grease is separated more, if the number is too large, the phenomenon that the taper unit 152 cannot be opened occurs. The number of the compression coil springs 154 should be appropriately adjusted when they are set according to slaughter waste.
The cover unit 153 is provided with an opening/closing portion 153a for cleaning the inside, repairing, and the like. The screen unit 140 is also provided with a screen opening/closing portion 143 for cleaning the inside, repairing, and the like.
The operation of separating the waste grease contained in the slaughter waste by the degreasing unit 100 having the above-described structure is specifically as follows.
First, when slaughter waste containing waste grease heated by the heating unit 12 is transferred to the upper side of the hopper unit 110, it is supplied to the main body unit 120 through the penetrating unit at the lower end thereof.
In the main body unit 120, the driving shaft 132 is rotated by the driving motor 133 so that slaughter waste put into the inside of the main body unit 120 through the hopper unit 110 is moved along the inside of the main body unit 120 by the rotation of the screw 131.
Slaughter waste moving along the inside of the main body unit 120, while passing through the screen unit 140, is compressed while reaching the cone unit 152 provided at the slaughter waste discharge unit 150. That is, slaughter waste is compressed by the cone unit 152.
Accordingly, when slaughter waste is continuously transferred to the cone unit 152, pressing force is generated to the slaughter waste by the cone unit 152, thereby compressing the slaughter waste, and at this time, waste grease flows out through degreasing holes formed in the screen unit 140 and is discharged through the waste grease discharging port 141 provided in the screen cover 142 to be supplied to and stored in the temporary storage unit 13b.
At this time, when slaughter waste (by-products) conveyed to the taper unit 152 and from which waste gas grease is removed gradually increases, the compression coil spring 154 is compressed due to an external force applied to the compression coil spring 154 which presses the taper unit 152. I.e. with separated slaughter waste (by-product)
The amount increases, pushing out the conical unit 152, compressing the compression coil spring 154. Thus, the taper unit 152 is gradually opened so that a large amount of slaughter by-products from which waste grease has been removed are squeezed out through the end of the taper unit 152 and discharged through the discharge port 151 provided at the cover unit 153, thereby being supplied to the drying unit 14.
Here, when the density of slaughter waste (by-products) is lowered, the compression coil spring 154 is gradually restored so that the diameter of the end of the taper unit 152 becomes small, and a small amount of slaughter by-products is discharged.
Fig. 6 shows a state when the least amount of slaughter by-products is discharged, a state when the moderate amount of slaughter by-products is discharged, and a state when the most slaughter by-products is discharged, respectively, through the taper unit 152.
As described above, the degreasing unit 100 can automatically extract waste grease according to the size of the transferred slaughter waste because the diameter of the tapered unit thereof can be automatically changed, thereby greatly improving the working efficiency.
As shown in fig. 2 (b), the degreasing unit 100 of the present invention may be provided in a tapered shape in which the size (diameter) thereof becomes smaller gradually as approaching the screen unit 140 from the end of the main body unit 120 and the screw 131 provided therein connected to the driving motor 133.
As described above, the slaughter by-products of fat are removed by the degreasing unit 100, which are supplied and stored to the drying unit 14. A stirring device (not shown) may be provided in the drying unit 14 for stirring the slaughter by-products.
Also, in the drying unit 14, the hot air generated by the hot air generating unit 20 may be supplied to dry the slaughter by-products. As described above, the slaughter by-product dried by the drying unit 14 can be used as feed or compost because it removes moisture or fat, and is convenient to transport and transport because of its light weight. In addition, if the dry slaughter by-product is subjected to landfill treatment in a landfill site, it can be said that the environment is protected because it can minimize the percolating water.
In addition, the present invention can be used after extracting the waste grease a stored in the main storage unit 13 c.
That is, as shown in fig. 8, the filtering means 30, refining means 40 and separating means 50 may be further connected to the main storage unit 13C of the present invention, thereby supplying the refined oil C obtained to the hot wind generating unit 20.
In this structure, the waste animal fat a stored in the main storage unit 13C is not directly burned for use, but the purified oil C is separated from the waste animal fat and used only as such, and therefore, the filter device 30 is intended to filter the waste animal fat a stored in the main storage unit 13C by using a filter net or the like of various shapes, thereby filtering out fine impurities, residues, and the like contained therein again.
The refining apparatus 40 for refining and refining the refined animal fat B passing through the filtering apparatus 30 may use the refining apparatus 40 of the known art. In the present invention, the waste animal fat a filtered by the refining apparatus 40 is referred to as refined animal fat B.
The separation device 50 is configured to separate, from the refined animal fat B extracted by the extraction device 40, 25wt% of methanol (CH 3 OH) and 0.5wt% potassium hydroxide (KOH) based on the total weight of the refined animal fat B, and then heating it to a user-specified set temperature in the refining apparatus 40, and then passing the user-specified set time. To this end, the separating apparatus 50 comprises: a mixing tub 51 for mixing refined animal fat, methanol and hydrogen oxide; a heating device 52 for heating the refined animal fat, methanol and hydrogen oxide in the mixing tub; temperature and time control means for adjusting the temperature and time of the heating means 52.
After a predetermined time, the Refined animal fat B is separated into a Refined Oil (C, C) layer and a Glycerin (D, D) layer in the mixing tub 51 because the Refined Oil C has a lower density than the Glycerin D, and thus the Refined Oil C layer is formed on the upper portion of the Glycerin D layer.
In summary, the hot air generating apparatus using waste animal fat according to the present invention includes: a conveying unit such as a conveyor belt or the like; a heating unit for heating the slaughter waste conveyed by the conveying unit; a degreasing unit for compressing slaughter waste heated by the heating unit to thereby generate waste gas grease; a storage unit for storing the waste grease degreased by the degreasing unit; and a hot air generating unit for supplying and burning the waste grease stored in the storage unit to generate hot air, the above units being sequentially connected to each other to degrease and store the waste grease contained in the slaughtered waste, and then supplying the waste grease with fuel and drying the object to be dried using the hot air generated during the burning.
