Abstract

<P>PROBLEM TO BE SOLVED: To provide a solid-liquid separator with improved water quality of drainage. <P>SOLUTION: The solid-liquid separator includes a container 18 having a built-in strainer 10 laminated with a ring 3, a scraper 16 scratching solid, an output port 20 opened to the side of the container 18 and an outlet 25 opened to the bottom, and a solid-liquid inlet 23 is opened to the side of the container 18 so as to face a notch 4 formed in the outer portion of the ring 3. A solid-liquid flows toward the clearances of the strainer 10 and enters the notch 4, leading to prevention of dissolution of fine solid in the liquid because there is no time for the solid to diffuse in the solid-liquid system. The solid having entered the notch 4 moves with the rotating strainer 10 and is removed by the scraper 16 and recovered from the output port 20. Liquid adhered to the solid passes through the clearances of the strainer 10 by self-weight and is discharged from the outlet 25. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a solid-liquid separation device that separates a solid-liquid mixed with solid matter such as crushed garbage into solid and liquid.

  Conventionally, this type of solid-liquid separation device is used for garbage disposal such as crushing and dewatering garbage generated in a kitchen or the like with tap water.

  FIG. 6 shows a specific example, in which a cylindrical strainer 102 formed by laminating a plurality of circular ring bodies 101 with a gap therebetween is rotatably provided in a cylindrical container 103.

  A plurality of circular ring bodies 101 constituting the strainer 102 are integrated by a connecting member 104, and a radial arm 106 having a rotating shaft 105 at the center is connected inward.

  Protrusions 107 protrude from the outer periphery of each circular ring body 101 at a predetermined angular interval, and when the strainer 102 is rotated via the rotating shaft 105, the tips of the protrusions 107 are the inner periphery of the container 103. It will move close to the surface.

  The liquid-liquid inlet 109 is suitable for the container 103 so that the solid-liquid inflow inlet 108 is opened at the bottom of the internal space of the strainer 102 so that the gap between the strainer 102 and the container 103 is the largest. Each part is formed.

  In addition, the container 103 enters a gap between a plurality of circular ring bodies 101 constituting the strainer 102 and scrapes off solid matter adhering to the circular ring body 101, and the solid scraped off by the scraper 110. An outlet 111 for discharging the object to the outside and a lid body 112 for opening and closing the outlet 111 are provided.

  The lid body 112 is rotatable via a hinge 113 and is normally biased and held in a closed position by the action of a spring 114 serving as a pressurizing means.

  First, the garbage and tap water charged in a crusher (not shown) are crushed, and then the mixed solid liquid flows into the container 103 from the inlet 108.

  And if the rotational force of drive parts, such as a motor, is transmitted to the rotating shaft 105 and the strainer 102 is rotated, the protrusion part 107 will scrape up a solid substance (crushed garbage).

  Thereafter, the solid matter riding on the protruding portion 107 and the solid matter adhering to the outer surface of the circular ring body 101 are peeled off by the scraper 110 and discharged from the outlet 111, and are collected by a drying or bioprocessing means.

  In particular, the solid matter is dehydrated when the lid 112 pressed against the scraper 110 by the spring 114 is pushed open.

  Further, liquid (tap water, garbage soup, etc.) adhering to the solid matter passes through the gap of the strainer 102 by its own weight and is discharged from the drain port 109.

On the other hand, most of the liquid in the solid liquid that has flowed into the container 103 immediately passes through the gap of the strainer 102 and is drained from the drain port 109 (see, for example, Patent Document 1).
Japanese Patent No. 3600474

  However, in the above-described conventional solid-liquid separator, the space of the container 103 in the vicinity of the inlet 108 is wide, so that the solid matter flowing into the container 103 from the inlet 108 is dispersed in the solid liquid by the stirring action of the protrusion 107 and is fine. Solid matter dissolves in the liquid.

  In addition, since the protruding length of the protruding portion 107 is smaller than the diameter of the inlet 108 and the operating portion of the protruding portion 107 faces obliquely downward, the solid matter flowing into the container 103 from the inlet 108 cannot be immediately scraped up. .

  Therefore, the solid matter is further dispersed in the solid-liquid, and the fine solid matter is dissolved in the liquid. As a result, since the liquid containing fine solids passes through the strainer 102 and is discharged from the drainage port 109, there is a problem that the quality of the drainage water deteriorates.

  Note that, when the diameter of the inlet 1108 is reduced, the scraping performance can be improved, but the passage resistance is increased and the solid matter is easily clogged.

  This invention solves the said subject, and it aims at providing the solid-liquid separator which improved the water quality of the waste_water | drain.

  In order to solve the above-described conventional problems, the present invention includes a cylindrical strainer formed by laminating a plurality of flat ring bodies with a gap therebetween, and the strainer is rotatably incorporated in a substantially cylindrical space. A container, a scraper for scraping off the solid matter adhering to the strainer, an outlet opening in the container located upstream in the rotation direction of the strainer with respect to the scraper, and a bottom surface of the container as it faces the strainer An outlet for draining the liquid that has passed through the gap of the strainer, and an inlet for solid-liquid inflow established on the side of the container, and the inlet of the ring body corresponding to the rotation of the strainer A notch that faces is formed.

  Accordingly, the solid liquid flowing into the container from the inlet immediately flows toward the gap of the strainer and enters the cut, and then the solid matter that has entered the cut is separated by the scraper and collected (discharged) from the take-out port.

  According to the solid-liquid separator of the present invention, the solid liquid flowing into the container from the inlet immediately enters the slit of the strainer, so that it is possible to suppress the fine solid matter from dissolving in the liquid, and the water quality can be greatly improved.

  The first invention is a cylindrical strainer formed by laminating a plurality of flat ring bodies with a gap, a container in which the strainer is rotatably built in a substantially cylindrical space, and an adherence to the strainer. A scraper for scraping off the solid matter, an outlet opened in the container located upstream in the rotation direction of the strainer with respect to the scraper, and a bottom surface of the container as it faces the strainer. An outlet for draining the liquid that passed through the gap and an inlet for solid-liquid inflow provided on the side of the container were provided, and a cut was formed in the outer shape of the ring body so as to correspond to the rotation of the strainer.

  Therefore, the solid liquid flowing into the container from the inlet immediately flows toward the strainer gap and enters the cut. That is, there is no time or space for solids to be dispersed in the solid-liquid, and fine solids can be prevented from dissolving in the liquid.

  Subsequently, the solid matter entering the cut moves along with the rotation of the strainer, is peeled off by the scraper, and is collected (discharged) from the take-out port. Moreover, the liquid adhering to the solid matter passes through the gap of the strainer by its own weight and is drained from the outlet. As a result, the water quality of the drainage can be improved.

  In the second invention, in particular, the inlet of the first invention is opened so as to face the incision rotating above the rotation axis and upward, so that the solid matter entering the incision is removed from the incision by the weight of the solid matter. Dropping can be suppressed. As a result, the solid matter is dispersed again in the liquid, and the fine solid matter is not dissolved in the liquid, so that the water quality of the drainage can be improved.

  In the third invention, in particular, in the first or second invention, a substantially horizontal introduction pipe is connected to the inlet.

  Thereby, since the solid liquid which flowed into the container from the inlet flows along the outer shape of the rotating strainer, the collision of the solid liquid with the strainer is mitigated. As a result, further mixing of the solid and liquid is prevented, so that the fine solid matter does not dissolve in the liquid and the water quality of the drainage can be improved.

  In a fourth aspect of the invention, in particular, in the first aspect of the invention, a cut is formed in each ring body so as to extend in the longitudinal direction of the strainer.

  Therefore, a large volume can be ensured as the cut, and a large solid or a solid solid can be taken in smoothly.

  In the fifth aspect of the invention, in particular, in the fourth aspect of the invention, the cut positions of the ring bodies are set so as to be shifted from the rotational direction so as to constantly face the entrance.

  Therefore, the solid matter that has flowed into the container from the inlet smoothly enters the cut.

  In a sixth aspect of the invention, in particular, in the first aspect of the invention, the cut is made in a substantially crescent shape.

  As a result, the solid liquid flowing into the container from the inlet immediately flows toward the strainer gap so as to fall into the bottom of the substantially crescent-shaped cut, and subsequently the solid matter that has entered the cut moves as the strainer rotates. At that time, the solid matter entering the cut can be prevented from falling from the cut due to the weight of the solid matter.

  As a result, the solid matter is dispersed again in the liquid, and the fine solid matter is not dissolved in the liquid, so that the water quality of the drainage can be improved.

  In a seventh aspect of the invention, in particular, in the first aspect of the invention, the inner part of the ring body is formed with a joint for joining the ring body through the vicinity of the cut.

  Thereby, since the junction is formed between the inner shape of the ring body and the cut, the strength of the ring body can be improved.

  As a result, the strainer gap can be secured, and the solids separation performance can be stabilized.

  In the eighth aspect of the invention, in particular, in the first aspect of the invention, the reinforcing portion is provided in the inner shape of the ring body corresponding to the cut.

  Therefore, even if the ring body has a cut, there is no problem in strength, and as a result, a gap between the strainers can be secured, so that the solid separation performance can be stabilized.

  Reference numeral 9 denotes an inner shape of the ring body 3, and a reinforcing portion in which the vicinity of the bottom of the notch 4 is expanded toward a substantially center. Reference numeral 10 denotes a cylindrical strainer. The layers are laminated so as to form the cut portion 11 so that the joint portion 5 is overlapped and the cut 4 is continuously located in the longitudinal direction.

  A fixing rod 12 is inserted into the communication port 8, and fixing means 13 (screws, E-rings, etc.) are attached to both ends of the fixing rod 12.

  Reference numeral 14 denotes a flat plate-like connecting portion obtained by extending the protruding portions 6 of some of the ring bodies 3 to the rotary shaft 1, and a hexagonal hole connecting port 15 is opened at a place where the plurality of connecting portions 14 are assembled, and A rotating shaft 1 of a hexagonal column is inserted into this connection port 15.

  Reference numeral 16 denotes a scraper having a tip projecting from the outside to the inside of each gap of the strainer 10, and is positioned (gap) by the scraper support plate 17.

  Reference numeral 18 denotes a container that forms a substantially cylindrical space with the rotation shaft 1 as a center, and in which the strainer 10 is rotatably built.

  Reference numeral 19 denotes a discharge passage formed so as to communicate the inside and outside with the side surface of the container 18 on the upstream side of the strainer 10 in the rotational direction with respect to the scraper 16. The width is the length in the cylinder direction of the container 18, and the height is the depth of the notch 4. It is set to the same size as the half.

  Reference numeral 20 denotes an outlet of the discharge passage 19 facing outward, which is opened and closed by a slidable lid 22 by a drive unit 21 from a solenoid or an electric motor.

Reference numeral 23 denotes an inlet corresponding to the gap of the strainer 10 above the rotating shaft 1 and opened to the side surface of the container 18 so as to face the notch 4 (notch portion 11) in the middle of rotating upward, and a crusher (not shown) Z) breaks up the garbage and mixes it with tap water.

  Reference numeral 24 denotes an introduction pipe that connects the crusher and the inlet 23, and the pipe is horizontally arranged in the vicinity of the inlet 23. Reference numeral 25 denotes a liquid discharge outlet opened at the lowest position in the strainer 10. A control part (not shown) controls the drive part 2 and the crusher.

  The operation of the solid-liquid separator configured as described above will be described.

  First, when garbage is thrown into the crusher and tap water is poured, the control unit starts driving the crusher and the drive unit 2. The crusher crushes the garbage and mixes it with tap water, and the solid liquid flows through the introduction pipe 24 and flows into the container 18 from the inlet 23.

  At the same time, the power of the drive unit 2 rotates the rotary shaft 1 and rotates the strainer 10 via the joint 5 and the connecting part 7.

  The solid liquid that flows into the container 18 and tries to flow horizontally comes into contact with the outer end surface of the rotating strainer 10 at an angle, so that it flows upward along the outer shape of the strainer 10. Change.

  As a result, since the frontal collision of the solid liquid with the strainer 10 and the notch 4 is mitigated and the solid liquid can be prevented from further mixing, it is possible to prevent the fine solid matter (crushed garbage) from dissolving in the liquid, Improves drainage water quality.

  In order to further prevent a frontal collision of the solid liquid with the strainer 10 and the notch 4, it is effective to pipe the introduction pipe 4 in the tangential direction of the rotating strainer 10. The connection to the inlet 23 causes a problem that heavy solids or solids that are difficult to flow accumulate in the introduction pipe 4.

  At the same time, the solid liquid immediately flows toward the gap of the strainer 10, and when the notch 4 reaches the inlet 23 due to the rotation, the solid liquid enters the bottom portion of the solid liquid.

  That is, unlike the conventional example, there is no need to scoop up the solid material, and the solid liquid flowing into the container 18 enters the cut 4 in a short time, so there is no time for the solid material to disperse in the solid liquid and the fine solid material. Can be prevented from dissolving in the liquid. As a result, the water quality of the drainage can be improved.

  On the other hand, a large volume can be secured in the cut 4, so that a large solid or a solid solid can enter the cut 4 smoothly.

  Subsequently, when the solid matter entering the cut 4 moves along with the rotation of the strainer 10, the cut 4 rotates upward (the open side of the cut 4 is located above the bottom). Does not fall out of the cut due to its own weight.

  As a result, the solid matter is dispersed again in the liquid, and the fine solid matter is not dissolved in the liquid, so that the water quality of the drainage can be improved.

  In addition, a liquid (tap water, garbage soup, etc.) adhering to the solid matter passes through the gap of the strainer 10 by its own weight and is drained from the outlet 25. On the other hand, most of the liquid in the solid liquid that has flowed into the container 18 immediately passes through the gap of the strainer 10 and is drained from the outlet 25.

Finally, the solid matter that has been moved along with the rotation of the strainer 10 and carried to the scraper 16 is peeled off from the cut 4 by the scraper 16 and moved to the discharge passage 19.

  Subsequently, the solid matter is filled in the discharge passage 19 by the passage resistance of the discharge passage 19 whose opening area is halved, and is compressed and dehydrated.

  The dehydrated liquid passes through the gap of the scraper 16 and returns to the container 18, and the dehydrated solid matter is discharged from the outlet 17.

  Since the connecting portion 5 or the reinforcing portion 9 is provided between the inner shape of the ring body 3 and the cut 4, the strength of the ring body 3 can be maintained even if the cut 4 is formed on the outer shape of the ring body 3. As a result, since the gap of the strainer 10 can be secured, the solid separation performance can be stabilized.

  One or more cuts 4 are required for the ring body 3.

(Embodiment 2)
4 and 5 show the second embodiment. The difference from the first embodiment is that the positions of the notches 4 are formed so as to be shifted by about half for every several pieces of the ring body 3, and the notches 11 are continuously formed at the inlet 23. FIG. This is the point that I faced.

  In addition, while attaching | subjecting the same code | symbol to the structure which carries out the same effect | action as FIG.1, 2, the thing of Embodiment 1 is used for concrete description.

  The solid liquid flowing into the container 18 from the inlet 23 immediately flows toward the gap of the strainer 10 and enters the cut portion 11.

  That is, since the solid matter can always enter the notch 4, it is possible to prevent the fine solid matter from being dissolved in the liquid until the notch portion 11 reaches the inlet 23 due to the rotation of the strainer 10. Improvements can be made.

  As described above, according to the solid-liquid separation device according to the present invention, since the solid-liquid that has flowed into the container from the inlet immediately enters the slit of the strainer, it is possible to prevent fine solids from being dissolved in the liquid, greatly improving water quality. For example, it can be expected to be used for kitchen cocoon processing.
