The present invention relates to a drying apparatus for forcibly drying livestock manure, such as food waste poured from homes, restaurants, kitchens, poultry or pig farms, livestock farms, poultry meal, and manure, and in particular, in a short time It can be dried quickly, and the manure smells such as ammonia gas and methane gas generated during the drying process can be completely burned by incinerator to solve the odor problem around food waste drying or livestock manure drying treatment plant. It relates to a dreg drying apparatus.

The livestock manure dryer disclosed in Utility Model Publication No. 92-8400 is to diffuse water vapor containing the manure odor from the manure drying room immediately to the atmosphere without reprocessing, or to send the condensation drying gas generated in the manure drying room to a condenser to condense it. Some live condensate livestock urine dryers deliver condensate to the storage tank and release the cooled gas into the atmosphere. However, the smell of ammonia, such as ammonia gas emitted from the manure drying room, has caused odor damage to residents near the livestock manure drying treatment plant.

The heating range is also limited to the portion below the middle height of the stirring barrel, so the drying time is slow and there is a problem economically. This heating structure is characterized by the difference between the surface temperature and the internal temperature in the upper part of the stirring tube, especially during winter, when the atmospheric temperature is low. Delays and drying treatment efficiency were below expectations.

In addition, the chemical pipes in the burner chamber complicated the internal structure of the dryer, especially the fire chamber, thereby increasing the manufacturing cost of the livestock manure dryer, and the stirring blade was a rod, which slowed down the drying efficiency due to the low stirring efficiency. In addition, since the agitator and thermal oil storage tanks are exposed all over the house without any heat insulation inside or outside, there is a risk of burns if the dryer accidentally touches the dryer during the drying operation. It's also inconvenient to clean up dirt that's attached to it.

In addition, the utility model registration application No. 93-31430 by the person is to heat the livestock manure by heating the main wall of the drying room and the stirring vane with the superheated steam, the medium-sized dryer is excessive energy cost, and the drying time is slow.

Moreover, all the livestock manure dryers thus far cannot be dried due to structural irrationality.

Accordingly, it is an object of the present invention to provide a high-performance livestock manure combined food drier drying apparatus that can dry food waste and livestock manure in a shorter time.

Another object of the present invention is to provide a warm air-type livestock manure combined food drier drying device that is removed in the air by removing the livestock manure smell, food waste odor when drying.

Another object of the present invention is to provide a warm air-type livestock wastes combined food drier drying device that can improve the drying efficiency by preventing the phenomenon of sticking to the corners, such as where wings and wing shafts meet when stirring the dry matter in the drying chamber will be.

The food-drying drying device combined with hot air livestock manure in this paper consists of a grinder, a hot air generator, a dryer, an incinerator and an odor remover. The crusher grinds the foreign materials such as sticks, gums, rubble, and wire that are mixed in the dry matter, and makes them easy to stir after input. The hot air generator blows high temperature hot air into the drying chamber to dry the dry object. In addition, the dryer is repeatedly dried by the hot air while stirring the input to dry the dried object is discharged to the outlet of the auxiliary wing chamber, and the steam and odor generated during drying is sent to the incinerator through the duct. In an incinerator, steam, odor molecules, gas, etc. drawn out from the dryer are incinerated by contact with a gold mesh.

In addition, the odor remover cools the gas from the incinerator to precipitate foreign matter and deodorizes the odor and sends only clean and clean air to the atmosphere.

Hereinafter, the present invention will be described according to the accompanying drawings created based on the preferred embodiments.

As shown in FIG. 1, the food waste drying apparatus combined with a warm air type livestock manure is composed of a dryer (A), a hot air generator (B), an incinerator (C), an odor remover (D), and a grinder (E). A conveyor (F) is installed between the grinder (E) and the inlet (11) of the dryer (A), and the exhaust hole (14) of the dryer (A) and the hot air generator (B) are connected to the hot air pipe (6). (A) and the incinerator (C) are connected to the duct (7) by the incinerator (C) and odor remover (D) by the conduit (8), respectively. In addition, the chain sprocket pinched at the end of the blade shaft 25 and the circulation blade 43 exposed outside the dryer A is powered by the chains 9a and b so as to be driven by one motor 10. Connect with

2 to 4, the auxiliary vane chamber (2) is provided in the drying chamber (1) of the dryer (A), and the auxiliary vane chamber is recessed downwardly along the longitudinal direction from the bottom center of the drying chamber (2). 3) a circulation vane 4 is provided. The stirring vane 2 attaches large and small spiral ribbon wings 21 and 22 concentrically. Pipe wing members 23 and 24 are attached between the ends of these ribbon blades 21 and 22, and the inner ends of these wing members 23 are fixed on the wing side 25. As shown in FIG. The wings 21 and 22 are symmetrically attached so that the dry matters are gathered from the both ends to the abdominal plate with the center of the wing shaft 25 as a point.

The inner ends of the blade support sections 23 and 24 communicate with the blade shaft 25 internally. The injection holes 23a and 24a are drilled on the blade support sections 23 and 24. These injection holes 23a and 24a are for blowing out the hot air flowing through the wing shaft 25.

As shown in FIG. 5, in the long blade support section 23, the injection hole 23a is drilled in the blade shaft 25 side part within the rotation radius of the short blade support section 24. As shown in FIG. The volume of the building decreases as its moisture gradually diminishes as it dries. For example, when the dry object to be dried is reduced below the rotation radius of the short wing support section 24, outwardly the rotation radius of the wing support section 24 in which the injection hole 23A of the long wing support section 23 is squeezed. When exposed, it becomes a non-resistance state and hot air concentrates into the injection hole outside the resistance that is not resisted, i.e., the injection hole outside the rotation radius of the short wing support 24, rather than the injection hole 24A of the short wing support 24 which is resisted. Will be. In this case, the dry matter is gradually reduced in volume as the drying proceeds, the drying will be further thereafter.

Therefore, there is a material that will allow the hot air to spread into the dry matter even if the volume of the dry matter decreases. Therefore, the long blade support section 23 punctures the injection hole 23a only in the portion within the rotation radius of the short blade support section 24.

In addition, when the injection holes 23a and 24b are placed in the direction in which the stirring vane 2 rotates, resistance from the dried object to stir the dried object is received. Resistance at this time prevents the spread of hot air. If the hot air does not spread smoothly, it will interfere with rapid drying. Therefore, the injection holes 23a and 24a are preferably drilled on the rear surface of the rotational direction which is much less resistant while the stirring vane 2 is rotated as shown in FIG.

The circulating vane 4 transfers a dry object to be pulled downward while being stirred by the stirring vane 2 toward the discharge port 12. The rear blade of the transfer blade 41 has a resistance blade 42 as shown in FIG. 3. ) The resistance blade 42 helps to return the dry object conveyed to the discharge port 12 against the transfer blade 41 and to be pushed toward the drying chamber 1 or discharged to the discharge port 12.

The air header 5 is installed outside the left and right sides of the auxiliary wing chamber 3. Each air header 5 has a bifurcated branch pipe 51. The end of each branch pipe 51 is connected near the bottom of the drying chamber 1 which meets the auxiliary wing chamber 3. And the air header 5 is connected to the conduit 6 with the valve (V1) to the outlet side of the hot air generator (B) to receive the hot air produced by the hot air generator (B). Hot air introduced into the air header 5 is blown out to both sides near the bottom of the drying chamber 1 via the individual branch pipes 51.

On the ceiling of the drying chamber 1, an inlet 11 for input of the dried object is formed, and a discharge port 12 that can be opened and closed by an automatic device G such as a hydraulic cylinder is formed at the outlet end of the auxiliary wing chamber 3. The ceiling of the drying chamber 1 is further connected with a duct 7 for discharging the dry gas in the drying chamber having a high temperature and high humidity, and the end of the duct 7 is connected to the incinerator C. The dry gas generated in the drying chamber (1) is heavy because of the moisture is not smoothly discharged to the incinerator (C) in the natural state. Thus, by installing a turbo fan (TF2) on the duct (7) to force the dry gas in the drying chamber (1) to be sent out to the incinerator (C).

In FIG. 1 again, the hot air generator B divides the inside of the main body into a refractory brick compartment b1 so that the hot air generated in the interior is stagnant to induce high temperature, and a through hole b2 through which hot air can pass through each partition. Leave it. An air damper b3 is provided at the inlet side of the main body, and a burner b4 is provided at the center of the outer surface of the air damper b3. Further, a turbo fan TF1 is provided on the outlet side of the hot air generator B, and the hot air pipe 6 is in contact with the wing side 25 and the air header 5 side, and valves V1, 2) Install. Hot air is forcibly blown off by the turbo fan TF1. The valves V1 and 2 select the supply of hot air.

Incinerator C forcibly introduces the hot and humid dry gas from the drying chamber 1 and burns it to the burner c1 provided on the inlet side. In the incinerator (C) is installed a gold net (c2). This gold screen (c2) is wound on a stainless steel sheet winding wind, the heat transfer effect is large. This gold mesh (c2) is prematurely reddened to completely burn the hot and humid dry gas. C3 denotes a fireproof insulation. The outlet of this incinerator (C) is connected to the odor remover (D) side with a conduit (8).

The odor remover D is formed of a watering device d1 and a deodorant layer d2. The sprinkling system (d1) cools the heat of the incinerator where the temperature rises during the incineration and even blows into the odor remover (D) and cools the heat immediately to reduce the risk of fire and reduce the risk of fire. This helps to prevent mixed foreign matter from flying into the atmosphere. Deodorant layer (d2) is made of a material having a deodorizing and filtering function such as activated carbon. In this case, odor particles such as food waste and manure odor are filtered out from the exhaust gas cooled by watering.

The grinding | pulverizing machine E is a well-known thing which consists of a rotating plate in which the grinding blade was formed in the equal part to the circumferential surface, and the fixed blade corresponding to this rotating plate, for example.

The method of drying food waste or livestock waste using the dryer of this paper comprised in this way is demonstrated. The hot air generator B, the crusher E, and the motor 10 are operated. In the grinder (E), dry matters such as food waste or livestock manure to be dried are pulverized. The purpose of grinding is to pulverize substances that are disturbed when the stirring and circulation are repeated by stirring vanes (2) and circular vanes (4) in the drying chamber (1), such as twigs, chips, gums, and rubble mixed in the dry matter. have.

The milled dry matter is loaded on the conveyor (F) and enters the inlet (11). In the drying chamber 1, since the stirring vane 2 and the circulation vane 4 are rotating, all the to-be-dried goods come to repeat stirring and circulation.

While stirring and circulation are repeated, the valves V1 and 2 are opened to supply a part of the hot air produced by the hot air generator B to the wing shaft 25 and another part to the air header 5 side at the same time. The hot air introduced into the blade shaft 25 is injected into the injection holes 23a and 24a through the wing supporting sections 23 and 24, and the hot air entering the air header 5 passes through the branch pipes 51 to form a drying chamber ( It is sprayed toward the bottom of 1). The hot air sprayed into the injection holes 23a and 24a of the wing support sections 23 and 24 is stirred and blown into the dry items to be transported to dry the dry items, and the hot air blown into the branch pipe 51 is the auxiliary wing room. (3) The object to be dried is dried in the vicinity. As the rotary and fixed sprays of hot air are simultaneously carried out, the dry matters are blown in one by one, and thus can be dried quickly and efficiently in a shorter time.

The stirring vane 2 stirs the dry object to the center, and the circular vane 4 continuously sends the dried object to the discharge port 12. However, since the discharge port 12 is sealed until the drying is completed, it can not go out of the dryer and circulates through the drying chamber 1. The dry object conveyed toward the discharge port 12 by the conveying blade 41 hits the resistive blade 42 and the conveyance is subjected to the resistance. From this point, the pump is pushed up to the drying chamber 1 and agitated again by the stirring vane 2, gathered in the middle of the drying chamber 2, crawling into the auxiliary vane 3, and again by the circular vane 4 toward the discharge port 12. Transferred. The dry matter is dried again during this cycle.

After this cycle is repeated for some time, the projection window 13 determines the dry state of the object. The drying proceeds about halfway and the valve V2 is closed when the volume is reduced below the rotation radius of the small wing 22. The hot air is then concentrated in the air header 5. From this time, direct hot air drying is performed at the bottom of the drying chamber 1. Thereafter, when it is determined that drying is completed through the see-through window 13, the valve V1 is even locked, and the discharge port 12 is opened to pour out the dry matter.

On the other hand, the hot and humid dry gas generated in the drying chamber 1 is blown into the duct 7 and directed to the incinerator C. In this incinerator C, the dry gas is completely incinerated while passing through the flame of the burner c1 and the gold net c2 that has been preheated by the flame.

After incineration, it is directed to the odor remover (D). In the odor remover (D), the blowing is completely eliminated by the real pipe (d1), and the incineration gas is almost cooled. Then, as it passes through the deodorant insecticide (d2), even odors and fine dust are almost completely removed, and only the clear air is dispersed into the atmosphere.

As described above, this paper suggests that the large and small ribbon-shaped wings of the stirring vane rotating in the drying chamber stir the dry matter better, while the hot air is blown out through the injection holes between the wing supports and the hot air radiating from both sides of the circular vane. Drying is promoted by the food waste or livestock manure in the drying chamber can be dried in a shorter time.

In addition, the gap is secured between the ribbon-shaped wing and the wing shaft, so that some parts of the building are not caught between the wing and the wing shaft while the building is being dried.

In addition, the drying gas generated in the drying chamber is sent to the incinerator early and completely incinerated, so that the drying is further promoted, and afterwards, the air is dispersed through the odor remover to the air to be cleared to prevent damage and dust problems.

In addition, foreign matters such as twigs, chips, gums, and rubble mixed in the dry matter are finely pulverized before being sent to the dryer, so the stirring vanes and the circular vanes are easily stirred and transported.
