Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention is applicable to the pollution caused when the collected gravel and sand are processed into high-quality concrete aggregate using a rewashing treatment device, other industries, and general households. This invention relates to a device for drying sludge-like waste that can be used as buried soil, fertilizer, etc. by drying the sludge-like waste after treating the sewage generated from the wastewater with chemicals.

(b) Prior art and problems to be solved by the present invention Conventionally, sludge-like waste was squeezed out using a squeezing machine and the residue was disposed of. Moreover, there is a possibility that the problem of horn horn may occur, and since the above-mentioned squeezing machine is very expensive, it is not possible to easily dispose of the sludge-like waste.

(C) Means for Solving the Problems In view of the above-mentioned conventional problems, the present invention has a cylindrical head having an exhaust port on an inclined base and legs having an exhaust passage. A horizontal outer body is provided, and a rotating shaft passes through the center of the cylindrical head of the outer body,
This rotating shaft is supported by a bearing provided on the base and linked to a drive motor.A rotating drum with many small holes is attached to the middle part, and the lower end of the rotating drum is attached to the right side of the cylindrical head. A waste input hopper is installed facing the right opening, and multiple burners are installed on the sides of the outer shell, and their flame injection tubes are inserted into the outer circumferential surface of the rotating drum through a hole in the cylindrical head. A burner is provided on the front side wall of the leg part provided with the discharge passage, and a flame injection tube thereof is made to protrude toward the rear side wall, thereby easily drying a large amount of sludge-like waste. This makes it possible to effectively use this waste as buried soil, etc., and also makes it possible to easily dispose of sludge-like waste without causing pollution problems.

(d) Embodiments and operations Embodiments of the present invention will be explained below with reference to the drawings.

In the figure, reference numeral 1 denotes a base, and its right side is connected to the right upper end of the machine frame 2, and its left side is supported by an inclination angle adjustment jack 3 fixed to the left side of the machine frame 2, so that it extends to the left side. It is slanted low.

4 is a horizontal outer body installed on the base 1, consisting of a cylindrical head 6 with an exhaust port 5 over its entire length and a leg 8 with an exhaust passage 7; , fireproof layer 9 using glass fiber, etc.
is provided.

10 is a rotating shaft passing through the center of the cylindrical head 6;
Bearings 11, 1 whose left and right sides are provided on the base 1
1, and its left end is linked to a drive motor 12 provided on the base 1. Further, 13 is a slide prevention collar of this rotary shaft 10, and 14 is a base 1.
This is a receiving roller for the slide prevention collar 13 provided above.

Reference numeral 15 denotes a rotating drum fixed to the outer periphery of the intermediate portion of the rotating shaft 10 by a radial support bone 16, and has a large number of small holes 17 drilled on its entire surface, and a plurality of small holes 17 arranged at intervals on the left and right on its inner surface. The ring 18 is reinforced with a transverse rib 19 connecting the rings 18.

20 is a waste input hopper attached to the right side of the cylindrical head 6 with its lower end facing the right side opening of the rotating drum 15; 21 is a plurality of burners arranged on the side of the outer body, and the flame jet A tube 22 is projected from a hole 23 provided in the cylindrical head 6 toward the outer peripheral surface of the rotating drum 15. It is preferable that the burner 21 is provided so that the direction of the flame injection tube 22 can be adjusted to the best angle in the horizontal and vertical directions.

Reference numeral 24 denotes a burner provided on the front side wall of the leg section 8 provided with the above-mentioned discharge passage, and its flame injection pipe 25 is made to protrude toward the rear side wall.

Further, 26 is a hopper for storing dried material, the upper end of which is fixed to the machine frame 2 and fitted onto the outside of the legs 8 of the outer body, and the lower end of which is provided with a hydraulic opening/closing damper 27. , this does not necessarily have to be provided.

In FIG. 3, 28 indicates a plurality of stirring blades attached to the inner peripheral surface of the rotating drum 15, and in FIGS. 4 and 5, 29 indicates a perforated blade provided at the right end of the rotating drum 15. The non-perforated portion 30 is a mounting rod that is fixed to the outer surface of the outer body 6 and whose tip end is inserted into the inside from the right side opening of the rotating drum 15. A sludge removal plate 31 is provided in contact with or in close proximity to the inner surface.

In addition, the cylindrical head 6 of the outer body and the rotating drum 15
is not limited to a cylindrical shape as shown in the drawings, but a rectangular tube shape may also be used.

Since the present invention is constructed as described above, when drying sludge-like waste using this, the burners 21 and 24 are ignited and the flame injection tube 2 is ignited.
2 and 25, the drive motor 12 is operated, and the rotating drum 15 is rotated as shown in FIG.
After rotating to the left in the figure, if the sludge-like waste is thrown into the right end of the rotating drum 15 from the input hopper 20, the sludge-like waste will be transferred to the left side while being stirred by the rotation of the rotating drum 15. During this time, the sludge-like waste is blown with flames that are injected from the flame injection pipes 22 of the plurality of burners 21 and blown through the large number of small holes 17 of the rotating drum 15, so that the sludge-like waste is rapidly dried. The particles are discharged from the left side opening of the rotating drum 15 and fall down the discharge passage 7 of the leg 8, but at this time, the flame jetted from the flame injection pipe 25 of the burner 24 is sprayed and the drum rotates. The flame is also blown onto the undried waste falling from the large number of small holes 17 of the drum 15, so that the sludge-like waste is completely dried and stored in the storage hopper 26.

Furthermore, when a plurality of stirring blades 28 are attached to the inner peripheral surface of the rotating drum 15 as in the embodiment shown in FIG. Since the blades 28 sufficiently agitate, drying by the burner 21 is performed more effectively.

Further, as in the embodiment shown in FIGS. 4 and 5 of the drawings, a non-perforated portion 29 is provided at the right end of the rotating drum 15, and a mounting rod is inserted into the inside from the right opening in correspondence with the inner surface of the portion 29. 30 is provided with a sludge removal plate 31, when sludge-like waste is charged from the input hopper 20, the sludge-like waste is transferred to the unperforated portion 2 of the right end of the rotating drum 15.
9, the drying process continues as it continues to the left without flowing out of the rotating drum 15, so that it can be reliably dried.

Further, in this case, the sludge-like waste adhering to the inner surface of the unperforated portion 29 at the right end of the rotating drum 15 is automatically scraped off by the sludge removal plate 31, so that the device cannot be operated continuously. This is something that can be done.

(e) Effects of the Invention As described above, the present invention transfers sludge-like waste from one side of the rotating drum to the other side while stirring, and during this time, the sludge-like waste is heated by a plurality of burners. The dried product is rapidly dried into granules by spraying flame from a flame injection tube and blown through the many small holes of the rotating drum, and then is discharged from the left side opening of the rotating drum and falls down the discharge path of the leg. In addition, the undried waste that falls from the many small holes of the rotating drum is sprayed with flame from the flame injection tube of the burner installed on the front wall of the leg, which makes it possible to quickly remove a large amount of sludge-like waste. It can be completely dried in a short amount of time.

However, since the dried waste can be used as buried soil or fertilizer, it has the characteristics that sludge-like waste can be easily and effectively disposed of without causing pollution problems.
