Description

  The present invention relates to a solid-liquid separation device that separates solid matter such as raw garbage mixed in a liquid from the liquid.

As a conventional solid-liquid separator, there is one as shown in FIG. As shown in the figure, the strainer 2 housed in the case of the solid-liquid separator 1 separates the inside of the case into an inner peripheral region A and an outer peripheral region B. The mixed liquid of the solid and liquid is introduced from the inlet 3, and the strainer 2 scoops up the solid from the mixed liquid accumulated at the bottom in the solid-liquid separator and filters the mixed liquid. The liquid that has filtered the solid matter and passed through the strainer 2 flows into the inner peripheral area A, and the liquid is discharged from the discharge port 4 to the outside.

  However, in the conventional solid-liquid separator, the inlet 3 for introducing the mixed liquid containing solid matter and moisture (disposer drainage) is provided at a position lower than the drain outlet 4 for draining the treated water after the solid-liquid separation treatment. Therefore, the position of the water surface in the solid-liquid separator is above the inlet 3. Accordingly, the strainer 2 rescues the solid matter from the mixed liquid accumulated at the bottom in the solid-liquid separator and transports it to the scraper 5, squeezes the moisture of the solid matter and discharges it from the discharge port 6.

  Therefore, the solid substance contained in the mixed solution stays in the mixed solution for a long time and is stirred for a long time, so that the quality of the waste water discharged from the solid-liquid separator is deteriorated. Moreover, the fats and oils adhering to the solid matter and the solid matter smaller than the gap between the strainers 2 are easily washed away and pass through the strainer 2, and there is a problem that the solid-liquid separation performance is not so good.

  An object of the present invention is to provide a solid-liquid separation device that improves the solid-liquid separation performance and improves the quality of waste water.

In order to solve the above problems, a solid-liquid separator of the present invention includes a strainer formed in a cylindrical shape by laminating a plurality of flat circular ring bodies at a predetermined interval and fixing to a rotating shaft, and the strainer.

An inlet for introducing a liquid mixture with a liquid; and a drain outlet provided in the inner peripheral region, for discharging the liquid that has passed through the circular ring body and entered the inner peripheral region from the outer peripheral region to the outside. A discharge port that is provided in the outer peripheral region and discharges solid matter after the liquid mixture is solid-liquid separated, and the introduction port is above the water surface position during drainage and above the drain port Provided in the The inlet and the outlet, wherein when viewed from the direction of the axis of rotation of the strainer to face the right and left around the rotary shaft, which is and provided above said rotary shaft, the solid and liquid When the mixed liquid is introduced into the strainer from the introduction port, the solid is immediately separated into the liquid and the liquid, so that the time for the solid to stay in water can be shortened. In addition, even solids and fats and oils that are smaller than the strainer gap can be attached to large solids and collected from the discharge port, improving the solid-liquid separation performance and improving the quality of the wastewater. Can be planned.

  According to the solid-liquid separation device of the present invention, when the mixed liquid of solid and liquid is introduced into the strainer from the introduction port by providing above the water surface position in the solid-liquid separation device during drainage, the solid and Since it is separated into a liquid, the time during which the solid matter stays in water can be shortened. In addition, even solids and fats and oils that are smaller than the strainer gap can be attached to large solids and collected from the discharge port, improving the solid-liquid separation performance and improving the quality of the wastewater. Can be planned.

A first invention includes a strainer formed in a cylindrical shape by laminating a plurality of flat circular ring bodies at a predetermined interval and fixing to a rotating shaft, and an accommodating portion for accommodating the strainer. A case in which the storage portion is separated into an inner peripheral region and an outer peripheral region by a strainer, and an introduction port that is provided in the outer peripheral region and introduces a mixed liquid of solids and liquid from the outer peripheral region toward the inner peripheral region When provided in the inner peripheral region, a drain port for discharging the liquid having entered the inner area from the outer peripheral region passes between said circular ring members to the outside, provided in the outer peripheral region, the mixed A discharge port for discharging solid matter after liquid-solid separation, and the introduction port is provided above the water surface position during drainage and above the drain port, The outlet is the stress When viewed from the direction of the Na of the rotary shaft opposed to the right and left around the rotary shaft, which is and provided above said rotary shaft, introducing the mixture of solids and liquid from the inlet to the strainer Then, since it will be isolate | separated into a solid substance and a liquid immediately, the time for a solid substance to retain in water can be shortened. In addition, even solids and fats and oils that are smaller than the strainer gap can be attached to large solids and collected from the discharge port, improving the solid-liquid separation performance and improving the quality of the wastewater. Can be planned.

In the first invention , since the position of the introduction port is provided above the drain port, the water level in the solid-liquid separation device during solid-liquid separation (during drainage) becomes a low position, and the solid and liquid are separated. When the mixed liquid is introduced into the strainer from the introduction port, the solid is immediately separated into the liquid and the liquid, so that the time for the solid to stay in water can be shortened. In addition, even solids and fats and oils that are smaller than the strainer gap can be attached to large solids and collected from the discharge port, improving the solid-liquid separation performance and improving the quality of the wastewater.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. It should be noted that the present invention is not limited only by this embodiment.

(Embodiment 1)
FIG. 1 is a front cross-sectional view of a solid-liquid separation device according to an embodiment of the present invention, and FIG. 2 is a side cross-sectional view of the solid-liquid separation device, which is a cross-sectional view along the rotation axis direction of FIG.

  As shown in FIG. 1 and FIG. 2, the solid-liquid separation device 10 includes a case 11 of the solid-liquid separation device, a strainer 12 that separates the solid and liquid in the mixed solution, and a scraper that peels the separated solid from the strainer 12. 13. It is comprised from the cover body 14 which extrudes a water | moisture content from a solid substance, and dehydrates, and the discharge port 15 which discharge | releases the dehydrated solid substance, and the rotating shaft 20 of the strainer 12 is driven with an electric motor (not shown).

  The lid 14 is constantly biased to the scraper 13 side by a spring 16 or the like at a constant pressure. Fulfill.

  The strainer 12 is formed in a cylindrical shape by laminating a plurality of flat circular ring bodies 17 at predetermined intervals and fixing them to the rotary shaft 20. Furthermore, the circular ring body 17 has protrusions 22 at several locations on the outer periphery, and these protrusions 22 are provided at the same positions as the circular ring bodies 17. Plays a role in catching solids.

  The inside of the case 11 is separated into an inner peripheral area A and an outer peripheral area B of the strainer 12 by the strainer 12. Is provided above the center of the axis. In the inner peripheral region B of the strainer 12, a drain port 19 for draining the waste liquid separated into solid and liquid by the strainer 12 to the outside is provided at a position lower than the introduction port 18.

  The scraper 13 is composed of a plurality of metal flat plates, and is alternately sandwiched between the plurality of circular ring bodies 17 constituting the strainer 12, and the tip enters between the end faces of the circular ring body 17 to form a circular shape. It arrange | positions so that the inner peripheral surface of the ring body 17 may be reached.

  The introduction port 18 and the discharge port 15 are opposed to the left and right with the rotation shaft 20 as a center when viewed from the direction of the rotation shaft 20 of the strainer 12, and are disposed above the rotation shaft 20. Thereby, the distance which moves the solid substance introduce | transduced from the inlet 18 and hooked by the protrusion 22 to the discharge port 15 can be shortened, and the collection | recovery speed | rate which collect | recovers solid substances can be accelerated. A rotatable rotating elbow 21 is provided at the tip of the introduction port 18 to facilitate connection to a pipe (not shown) from a disposer (not shown).

  Next, the operation of the solid-liquid separator 10 will be described. An electric motor (not shown) is connected to the rotating shaft 20 of the strainer 12, and the strainer 12 rotates in accordance with the operation of a disposer (not shown) incorporated in the same system kitchen. In this form, it rotates counterclockwise. As a result, the protrusions 22 on the circumference of the strainer 12 come out of the state immersed in the liquid mixture below the case 11 and rotate so as to approach the introduction port 18, the scraper 13, the lid body 14, and the discharge port 15 in this order. .

  In this state, a mixed liquid of solids and liquid pulverized by the disposer (for example, drainage of a sink including solids) is introduced onto the strainer 12 through the introduction port 18. Then, the liquid flows through the gap between the circular ring bodies 17 of the strainer 12 and flows downward, and the solid matter is caught by the protrusion 22 of the strainer 12 and remains, so that the introduced mixed liquid is separated into the solid matter and the liquid. Is done.

  The rotating strainer 12 moves the solid matter caught on the protrusion 22 of the strainer 12 to the discharge port 15 in the circumferential direction of the strainer 12. In front of the discharge port 15, the scraper 13 separates the solid matter from the strainer 12. At the same time, the solid matter is pushed to the scraper 13 side by the lid body 14 to squeeze the moisture, and is discharged to the outside through the discharge port 15.

  As described above, the solid-liquid separation device according to the embodiment is separated into a solid and a liquid at the same time when the mixed liquid of the solid and the liquid is introduced into the strainer 12 from the inlet 18. The time during which the product stays in the liquid is shortened, and the components of the separated solid matter dissolve in the liquid and do not contaminate the water quality of the waste water.

  Further, even a small solid material that can pass through the strainer 12 can be attached to the surface of the large solid material caught on the strainer 12 and recovered from the discharge port 15, so that the small solid material is mixed into the waste water. It is possible to reduce the rate of wastewater and suppress water pollution of the wastewater.

  In addition, since the introduction port 18 is provided so as to introduce the mixed solution in the horizontal direction or obliquely downward from the outer peripheral region B toward the inner peripheral region A, the mixed solution directly enters the gap of the strainer 12, Since the speed increases and the time for the solid matter to stay in the water can be further shortened, the water quality of the drainage can be improved.

  In addition, although the above embodiment demonstrated the example which provided the protrusion 22 on the outer periphery of the strainer 12, it cannot be overemphasized that it replaces with the protrusion 22 and the same effect is acquired even if it implements by providing a recessed part. Yes. Moreover, a filter may be added to the drain port 19 to collect small solids that have passed through the gaps of the strainer 12.

  As described above, the solid-liquid separator according to the present invention is extremely effective as a garbage disposal system incorporated in a system kitchen or the like.
