Description

[0001] The present invention relates to an apparatus for separating solid liquid from stock,

More particularly, the present invention relates to an anaerobic digester which removes water by using high pressure without adding additives such as sawdust, thereby efficiently removing water contained in the manure.

Generally, the sludge solid-liquid separator is roughly classified into a centrifugal force type and a compression screw type.

As shown in Patent Registration No. 10-0817483, a method using centrifugal force is a method in which sludge is put into a drum made of a perforated plate and rotated so that the solids remain in the drum and the moisture is discharged to the outside through the pores. This method using centrifugal force is costly in the automatic continuous operation, so that it is actually difficult, the noise due to rotation occurs, and the water removal efficiency is very low compared to the amount of energy supplied.

As a method of using a compression screw, as disclosed in Japanese Patent Application Laid-Open Nos. 10-1999-0070305 and 10-0879714, a compression screw is installed inside a filter tank to rotate the raw water by the compression screw, The solids are separated and guided to the respective designated places. In the method using the compression screw, the reverse flow phenomenon occurs through the clearance of the edge of the compression screw during the transfer of the sludge, so that it is not easy to remove moisture and it is inevitable to add sawdust or the like to prevent it.

In addition, Japanese Patent Laid-Open No. 10-0614759 discloses that the moisture removal rate can be controlled by adjusting the size of the opening portion using a plurality of square rods using a compression screw. However, in the solid-liquid separator having such a structure, moisture is separated by the pressure of the compression screw, but there is a problem that the sludge flows backward through the gap of the compression screw, so there is a limit to apply pressure.

As shown in these drawings, the anaerobic digester according to the present invention comprises a main body 10 having an inlet 11 and an outlet 12; A cylindrical filter (20) installed in the main body; A compression screw (30) for compressing and transporting the intraglomerular fluid introduced through the inlet (11) of the main body (10) to the discharge port (12); A screw-type dewatering device 40 installed in the inlet 11; .

The main body 10 has an inner hollow cylindrical shape and is firmly fixed to the upper end of the pedestal 13 such that the longitudinal direction thereof is horizontally positioned. An inlet port 11 through which mannitidal fluid is introduced is formed at an upper end of the main body 10 and a discharge port 12 through which the human feces is discharged is formed at the other end. A collecting part 14 for collecting water is formed at the lower part, And is discharged to the outside through the pipe (90).

A filter 20 made of a cylinder is installed inside the body 10. The filter 20 has a number of eyes. The size of the eye 20 is such that the solids of the male and female are not able to pass through the solids of the male and female, . The outer diameter of the filter 20 is smaller than the inner diameter of the main body 10 so that a predetermined space is formed between the main body 10 and the filter 20. Here, the space is enough to allow the water to flow out. Both ends of the filter 20 are fitted and fixed to both side assemblies formed in the main body 10. [

The compression screw 30 is horizontally disposed inside the filter 20 so that a spiral wing 32 is protruded around the horizontal rotary shaft 31 to transfer the intruded menstrual fluid between the wings 32 . Here, the diameter of the rotary shaft 31 gradually increases toward the distal end so that the transfer space of the mannitol is gradually narrowed so that the mannitol is compressed. In addition, the edge of the blade 32 is designed to be close to the inner diameter of the filter 20, minimizing backflow into the space between the blades 32 and the filter 20 upon transferring the malodor, Is discharged through the filter 20 and only the solids are transported. Both ends of the compression screw 30 are fitted to bearings provided at both ends of the main body 10 so as to rotate and receive power from the motor M and the speed reducer T provided at one end of the main body 10 and rotate . The bearing on the side of the discharge port 12 is fitted in the center of a circular bearing 15 fixed to the main body 10. The bearing 15 is formed with a plurality of through holes 16, So that the transferred molten solids are passed through the through-hole 16.

The discharge port (12) is provided with an opening / closing means (60) which is opened or closed only at a predetermined pressure or more. The opening and closing means 60 includes a discharge pipe 61 penetrating in the longitudinal direction, a fixture 62 provided at the center of the discharge port 12, an opening and closing plate 63 for blocking the discharge opening 12, And a spring 64 for returning the spring 64. [

The discharge pipe (61) has an elongated cylindrical pipe shape and is in tight contact with the discharge port (12) to communicate with the discharge port (12). A fixture 62 is provided at the center of the discharge port 12, and the fixture 62 is formed to be gradually narrowed as the tip thereof protrudes from the cylinder. The fixing member 62 may be integrally formed at the tip of the rotary shaft 31 or assembled to the rotary shaft 31 as shown in the figure. Or the bearing (15). Inside the discharge pipe (61) is formed a cylinder and an opening / closing plate (63) formed through the discharge passage (65) is built in the center and slidingly moves in the discharge pipe (61). The discharge passage 65 of the opening / closing plate 63 is formed to be smaller than the outer diameter of the fixture 62. A spring 64 is provided at the rear of the opening / closing plate 63 to closely contact the opening / closing plate 63 opened by the discharged manure. When the pressure in the main body 10 is not generated by this structure, the open / close plate 63 is kept in close contact with the fixture 62, When the pressure is increased, the opening and closing plate 63 moves backward and the discharge passage 65 is opened. As a result, the main body 10 is discharged through the discharge passage 65, The opening / closing plate 63 is restored to its original state by the spring 64 and closed.

The opening and closing means 60 can be simplified as an opening and closing plate 63 which is in close contact with the discharge opening 12 and a spring 64 which brings the opening and closing plate into close contact with the discharge opening 12.

The discharge pipe 61 is split into two bodies 61a and 61b and is connected to the one body 61b by a handle 66 so that the length of the discharge pipe 61 So that the elastic force of the spring 64 is adjusted. When a bolt hole is formed in the body 61b provided with the handle 66 and a male screw thread is formed on the one handle 66 so as to protrude into the body 61b by rotating the handle 66, Is locked by a thread of the inner body 61a so as to maintain a length-adjusted state.

A screw type dewatering device (40) is installed in the inlet (11) of the main body (10). The screw type dewatering device 40 includes a cylindrical outer cylinder 41 vertically installed and an inner cylinder 42 having a filter function provided in the outer cylinder 41 and a scraper 43 provided on the inner cylinder 42 A compression screw 44 provided at a lower portion of the scraper and an opening and closing means 60 provided at an outlet 48 of the inner cylinder 42.

The outer cylinder 41 has a cylindrical shape having a space therein and is installed perpendicularly to the inlet 11 of the main body 10. The upper portion of the outer tube 41 is connected to a supply tube 47 through which the intestinal menstrual fluid is supplied to supply the intestinal menstrual fluid into the inner tube. The supply pipe 47 is installed horizontally on the side surface of the outer tube 41 so as to be tangential to the inner tube 42 and natural supply is provided along the inner circumference of the inner tube 42 when the males are fed. On the other hand, the high-pressure pump P is installed in the supply pipe 47 to force the male feces to the inner cylinder 42, and the water passes through the inner cylinder 42 by the high pressure. A return pipe 46 is provided on the upper portion of the outer tube 41 to allow the molten human body to be collected into the fermentation tank through the return pipe 46 when the supply of the molten fat is further difficult due to the pressure inside the outer tube 42.

The inner cylinder 42 is formed in a cylindrical shape having numerous eyes, and the size of the eyes is formed to a size such that only the water can pass without passing through the solids of the male and female. The outer diameter of the inner cylinder 42 is smaller than the inner diameter of the outer cylinder 41 so that a predetermined space is formed between the outer cylinder 41 and the inner cylinder 42. The inner cylinder 42 is composed of two upper and lower bodies 42a and 42b and the upper body 42a has a constant diameter and the lower body 42b has a conical shape that gradually becomes narrower toward the lower side And an outlet 48 is formed in the lower portion. A scraper 43 is installed in the upper body 42a and a compression screw 44 is installed in the lower body 42b. As shown in FIG. 3, the scraper 43 is coupled to the rotary shaft 44a by a rotary holder 43a projecting in four directions. The rotating holder 43a is formed with a square mounting groove 43b in the vertical direction at the end protruding in all directions and an opening groove 43c opened from the mounting groove 43b to the terminal end in a narrow area is formed, And the scraper blade 43d is slidably engaged with the groove 43c. The scraper blade 43d has an elongated fitting portion 43e having the same shape as the fitting groove 43c and has a soft elastic portion 43f protruding from one side thereof. A neck portion inserted in the opening groove 43c is recessed between the fitting portion 43e and the elastic portion 43f so as to be detachably attached to the rotary holder 43a. As shown in the drawing, the scraper blade 43d may be formed to be gradually narrower or thinner toward the distal end, so that the scraper blade 43d may have an elastic restoring force. It should be noted here that the scraper blade 43d can be made of a long and thin brush. The scraper 43 is in contact with the inner circumferential surface of the inner cylinder 42 and is conveyed, so that the scraper 43 does not pass through the inner cylinder 42 and scrapes the sticking solid material downward.

On the other hand, the compression screw 44 provided at the lower portion of the scraper 43 is formed integrally with the rotary shaft 44a and is provided close to the inner surface of the lower body 42b. Since the lower body 42b is gradually narrowed toward the lower side, the wings 44b of the compression screw 44 are formed to be gradually smaller toward the lower side according to the lower body 42b. Therefore, the molten human body dropped by the scraper 43 is compressed by the compression screw 44, and water is discharged through the inner cylinder 42, and only the solid matter is transferred to the lower discharge port 48. The discharge port (48) is provided with an opening / closing means (60) which is opened only at a predetermined pressure or more, and the solid material is discharged when the set pressure is reached.

The opening and closing means 60 includes an opening and closing plate 63 which is in close contact with and spaced from the discharge opening 48 and a spring 64 which returns the opening and closing plate 63. When the pressure in the outer tube 41 is not generated by this structure, the opening / closing plate 63 is kept in close contact with the discharge port 48, so that the intraglomerular menstruum that continuously flows into the body is finally compressed, When the pressure in the inner cylinder 42 is lowered as the pressure is increased, the drain port 48 is opened while the opening / closing plate 63 is moved downward, , The opening / closing plate 63 is restored to its original state again to be closed, and again the molten human body is compressed.

In addition, a transfer pipe (90) is provided at a lower side of the outer tube (41), and water filtered from the molten fat is discharged through the transfer tube (90). A cleaning pipe 91 is connected to the transfer pipe 90 so that the cleaning water can be forced into the outer pipe 41 to clean the inside of the pipe. When the cleaning pipe 91 is installed, a valve is installed in the cleaning pipe 91 and the transfer pipe 90 to block the transfer pipe 90 during the cleaning. When the transfer pipe 90 is used, .

The function and effect of the stool type solid-liquid separator according to the present invention having such a structure will be described in detail as follows.

First, when the intestinal mucilage is supplied to the inner cylinder 42 through the supply pipe 47 using the high-pressure pump P, the intestinal menorrhage flows into the upper body 42a and pressure is generated in the inner cylinder 42, (42). ≪ / RTI > At this time, the water contained in the intestinal mucosa is discharged, but the solids can not pass through and stick to the inner tube 42. The molten manure sticking in this manner is scraped off by the rotating scraper 43 and falls on the lower compression screw 44. The lowered body 42b is lowered toward the lower part by the lower body 42b and the compression screw 44. The lower end of the lower body 42b and the lower end of the lower body 42b are compressed by the compression screw 44. As a result, Is discharged through the eyes of the lower body 42b. In this process, as the pressure of the inner cylinder 42 increases, the water removal efficiency increases. When the pressure of the inner cylinder 42 becomes a predetermined value or more, the opening / closing plate 63 provided at the discharge port 48 is pushed downward The discharge port 48 is opened and the feces is discharged into the filter 20 of the main body 10 through the inlet port 11 as the shutoff plate 63 is transported downward. Here, the pressure value of the inner cylinder 42 for moving the opening / closing plate 63 follows the elastic modulus of the spring 64 for returning the opening / closing plate 63. When the pressure in the inner cylinder 42 is lowered, the opening / closing plate 63 is returned by the spring 64 and is brought into close contact with the rotary shaft 44a of the compression screw 44 to close the discharge passage 65, The discharge process is repeated. In this process, if the supply of the intact human milk is not smooth due to the internal pressure of the outer tube 41, the intraglomerular intrusion which is introduced through the return tube 46 provided in the supply tube 47 is recovered and then guided to the supply tube 47.

The discharged water is collected at the lower part of the space between the inner cylinder 42 and the outer cylinder 41 and guided to the water treatment tank through the transfer tube 90 installed in the outer cylinder 41.

On the other hand, the molten person's body having the first water removed by the screw type dewatering device 40 flows into the filter 20 of the main body 10. When the opening and closing plate 63 of the screw- The malnourished menstrual stream flowing into the main body 10 can not flow backward but is transported only toward the discharge port 12. The infusion of the above-mentioned molted mannitol is conveyed to one side by the compression screw 30 provided inside the filter 20. In this process, since the rotary shaft 31 of the compression screw 30 gradually expands toward the distal end, the transfer space of the stomachs is gradually narrowed, thereby compressing the intestinal menstruum naturally. That is, the moisture of the intestinal mucosa is discharged to the outside of the filter 20 through the filter 20, and the discharged water is collected in the lower collecting part 14 of the main body 10 and then guided to the water treatment tank through the transfer tube 90 . When the pressure in the main body 10 is increased, the pressure of the solids from which the moisture is removed continues to be compressed and the opening / closing plate 63 is pushed by the pressure so as to be spaced from the fixture 62 and the discharge passage 65 is opened, The compressed solid material is discharged through the discharge port 65. When the pressure in the main body 10 is lowered due to the discharge of the intensive human body, the opening and closing plate 63 is returned by the spring 64 and is brought into close contact with the fixture 62. As a result, the discharge passage 65 is blocked, The process is repeated.

In this way, the first water is removed by the screw type dewatering device 40, and the water is introduced into the main body 10 to remove secondary water, and the water is removed by compressing the intestinal fluid.

FIG. 5 is an exemplary view showing the structure of an intact anaerobic digester according to another embodiment of the present invention. As shown in the figure, a cylindrical type dewatering device 40 is provided between an inlet 11 of a main body 10 and a screw- And a dehydrator 50 is provided to remove moisture through the third stage.

A cylindrical dewatering device 50 is installed in the inlet 11 of the main body 10 and a screw type dewatering device 40 is installed on one side of the cylindrical dewatering device 50, The body water 10 is removed by the main body 10 after the first-order moisture is removed from the cylindrical dewatering device 50 to be secondly dewatered.

Since the main body 10 and the screw-type dewatering device 40 are as described above, the description of their structure is omitted.

The cylindrical dewatering device 50 includes an outer cylinder 51, an inner cylinder 52, a supply cylinder 54, and a hydraulic cylinder 55. The outer cylinder 51 has a space therein, And is connected to the inlet 11 of the main body 10 and the supply pipe 54 is horizontally installed near the discharge port 53. [ Here, the supply pipe 54 is connected to the outlet of the screw-type dehydrator 40. The inner cylinder 52 is formed of a cylinder having a plurality of fine eyes penetratingly formed therein and spaced apart from the inner wall of the outer cylinder 51, and has a filter function to pass only water contained in the molten human body. The hydraulic cylinder 55 is provided on the upper portion of the outer cylinder 51 and the opening 53 is provided with opening / closing means 60 which is opened only by a predetermined pressure or more.

The hydraulic cylinder 55 is composed of a cylinder body 55a, a cylinder rod 55b, and a piston 55c. The cylinder body 55 is vertically installed on the upper portion of the outer cylinder 51. The cylinder rod 55b penetrates the upper portion of the outer cylinder 51 and is projected and retracted into the inner cylinder 52. [ The end of the cylinder rod 55b is provided with a piston 55c which is in tight watertight contact with the inner circumference of the inner cylinder 52 to forcefully compress the intestinal menstrual flow introduced into the inner cylinder 52.

The opening and closing means 60 includes an opening and closing plate 63 which is in close contact with and spaced from the discharge opening 53 and a spring 64 which returns the opening and closing plate 63. The opening / closing means 60 prevents the intraglomerular flow discharged from the cylindrical dewatering device 50 from flowing into the inlet 11 of the main body 10 and flowing backward.

The cylindrical dewatering device 50 having the above-described structure is supplied with the male dungue from which the first water has been removed from the screw type dewatering device 40 through the supply pipe 54. More specifically, the supply pipe 54 of the cylinder type dewatering device 50 and the discharge port 53 of the screw type dewatering device 40 are communicated with each other, and the cylinder rod 55b is lowered by the oil pressure, When the pressure in the inner cylinder 52 gradually increases, the opening / closing plate 63 of the opening / closing means 60 is pressed against the spring 64 And is separated from the discharge port 53 and opened. At the same time the outlet 53 is opened and the moisture is removed, the intestinal mucilage flows into the main body 10 through the inlet 11. Since the opening and closing means 60 provided in the discharge port 53 of the screw type dewatering device 40 acts as a check valve in the process of descending and compressing the piston 55c, . That is, the molten human body flowing through the supply pipe 54 moves only in the direction of the inlet 11 of the main body 10. When the intestinal mucilage flows into the main body 10 and the pressure of the outer barrel 51 is lowered, the opening / closing plate 63 is moved by the spring 64 to shut off the discharge port 53, So that it can not flow back to the cylindrical dewatering device (50). The moisture discharged in the above process is transferred to the water treatment tank through the transfer pipe 90.

In the present invention having the above-described structure, the first type of water is removed by the screw type dewatering device (40), and then the intraglottal body is introduced into the cylindrical dewatering device (50) to be secondly dewatered. The water removal rate is very excellent.
