Description

  The present invention relates to a cyclonic separator for separating and removing solids from a liquid.

  For example, in a cyclone separator that separates and removes solids such as sludge from a liquid such as a coolant discharged from a machine tool, the solids are separated while swirling the liquid in an inverted conical separator body.

  In this type of cyclonic separator, in order to properly swirl the liquid in the separator body, the liquid flows into the separator body so as not to impair the centrifugal force acting on the sewage, and the centrifugal force acting on the liquid. It is important that the liquid after removing the solid matter is allowed to flow out of the separator main body so as not to damage the surface.

  Therefore, as in Patent Document 1 and Patent Document 2, normally, the inflow pipe located upstream of the cyclone separator is connected in the tangential direction of the separator body, and the outflow located downstream of the cyclone separator. In a configuration in which the pipe is connected vertically (substantially perpendicular to the inflow side pipe) from the upper end, which is one end in the axial direction of the separator body, the liquid flows into the separator body in the tangential direction and is separated. The liquid flows out in the axial direction of the vessel body.

  According to the present invention, since the inflow portion and the outflow detour portion are arranged substantially parallel to each other, they can be easily connected to the inflow piping and the outflow piping and can be easily installed.

It is the block diagram which fractured | ruptured a part which shows the structure of the cyclonic separator which concerns on one embodiment of this invention. It is sectional drawing which shows the connection body in a cyclone type separator same as the above. It is sectional drawing which shows the introduction path of the connection body in a cyclone type separator same as the above.

  Hereinafter, the configuration of an embodiment will be described in detail with reference to the drawings.

  In FIG. 1, reference numeral 1 denotes a cyclonic separator. The cyclonic separator 1 is installed in a piping path of a liquid processing system for processing a liquid which is sewage such as a coolant liquid of a machine tool, for example, sludge. The solid matter is separated and removed from the solid matter mixed liquid 2 mixed with the solid matter.

  That is, the cyclonic separator 1 is installed between an inflow pipe (not shown) located on the upstream side in the piping path and an outflow pipe (not shown) located on the downstream side in the pipe path, and contains solid matter flowing in from the inflow pipe. The solids are separated and removed while the liquid 2 is swirled inside, and the separated liquid 3 from which the solids have been separated and removed flows out to the outflow pipe.

  The cyclone separator 1 is provided with a connection body 5 connected to a pipe path of a liquid processing system on an upper portion of a substantially inverted conical cylindrical separator body 4 that separates and removes solid matter from a solid-containing liquid 2 inside. It has been.

  The separator body 4 has a substantially inverted conical cylindrical portion 11 into which the solid-containing liquid 2 flows. The conical portion 11 is provided with an inflow port (not shown) through which the solid substance mixed liquid 2 flows through the connecting body 5 at an upper end portion which is an end portion on one side in the axial direction. It is formed in a tapered shape having a smaller diameter toward the lower side.

  A cylindrical inner cylinder portion (not shown) is concentrically attached in the inflow port. In the inner tube portion, the separation liquid 3 flowing from the conical portion 11 flows out from the outlet at the upper end. That is, in the separator body 4, the separation liquid 3 from which the solid matter is separated by the conical portion 11 flows out to one side in the axial direction through the outlet.

  A sludge pot, which is a storage part (not shown) in which the solid matter separated from the solid matter mixed liquid 2 is stored, is connected to the lower end part that is the other end part in the axial direction of the separator body 4.

  The separator body 4 swirls the solid-mixed liquid 2 that has flowed into the interior through the inflow port between the conical portion 11 and the inner cylindrical portion, and has a taper on the inner peripheral surface of the conical portion 11. The solid is centrifuged from the solid-containing liquid 2 while flowing downward along the line. Further, the separated solid matter is precipitated at the lower part in the conical portion 11, and the separation liquid 3 from which the solid matter has been separated is caused to flow upward from the outflow port, which is one side in the axial direction. Note that the solid matter separated from the solid matter mixed liquid 2 is discharged from the conical portion 11 to the sludge pot.

  As shown in FIG. 2, the connection body 5 has an introduction path 12 that communicates with the inside of the inflow pipe and the separator body 4, and a lead-out path 13 that communicates with the inside of the outflow pipe and the separator body 4. The introduction path 12 guides the solid-mixed liquid 2 from the inflow pipe between the conical part 11 and the inner cylinder part in the separator main body 4, and the outlet path 13 is an outlet of the separator main body 4. The separated liquid 3 is guided to the outflow pipe.

  The introduction path 12 is provided so that the inflow portion 14 connected to the inflow pipe is substantially parallel to the inflow pipe. That is, the inflow portion 14 is opened from the inflow piping in a straight line shape in a cross-sectional view substantially horizontally.

  An inflow detour portion 15 is connected to an intermediate portion of the inflow portion 14. The inflow detour portion 15 has a first detour portion 16 that is linearly opened downward from the inflow portion 14 in a straight line and a lower end portion of the first detour portion 16 that is substantially vertically opened in the horizontal direction. And a second detour unit 17. That is, the inflow detour portion 15 is formed in an approximately L shape in a cross-sectional view from the inflow portion 14 downward.

  An inflow opening 18 that is opened in a circular shape and communicates with the inflow port of the conical portion 11 is connected to the tip of the second detouring portion 17 that is opposite to the first detouring portion 16. The inflow opening 18 is disposed concentrically with the inlet of the conical portion 11.

  The second bypass portion 17 is connected in a tangential direction to the inner peripheral surface of the inflow opening 18. That is, the second detour portion 17 guides the solid-mixed liquid 2 through the inflow opening 18 in the tangential direction with respect to the inner peripheral surface of the conical portion 11.

  In addition, in the introduction path 12, if the opening area of the inflow detour portion 15 is smaller than the opening area of the inflow portion 14, the solid mixed liquid 2 is added due to the difference in opening area when flowing into the inflow detour portion 15 from the inflow portion 14. This is preferable because a swirl force is easily applied to the solid-mixed liquid 2 that is pressed and flows into the inflow opening 18 from the inflow detour portion 15.

  In the lead-out path 13, an outflow portion 21 that is opened linearly in a vertical direction in a cross-sectional view is connected to the lower end portion of the outlet of the inner cylinder portion of the separator body 4. That is, the outflow portion 21 is connected to the separator body 4 in the axial direction and is arranged concentrically with the outlet of the inner cylinder portion.

  An outflow detour portion 22 that is substantially perpendicular to the outflow portion 21 is connected to the upper end portion of the outflow portion 21 opposite to the inner cylinder portion.

  The outflow detour portion 22 is opened substantially linearly in a straight line and connected to the outflow pipe. In addition, the outflow detour portion 22 is disposed substantially parallel to the outflow pipe and is disposed above the second detour portion 17 in the inflow detour portion 15.

  That is, in the connecting body 5, the inflow portion 14 and the outflow detour portion 22 are disposed so as to be positioned on the extension line substantially horizontally, and the inflow detour portion 15 is disposed so as to wrap around under the outflow detour portion 22. Yes.

  When forming the connection body 5, for example, a molded body having the introduction path 12 shown in FIG. 3 is first injection-molded using a mold, and then a molded body having the introduction path 12 using another mold. A molded body having a lead-out path 13 in the upper part is injection-molded and integrally molded.

  Next, the operation and effect of the one embodiment will be described.

  When the solid matter is separated and removed from the solid matter mixed liquid 2 by the cyclone separator 1, first, the solid matter mixed liquid 2 flows into the introduction path 12 of the connection body 5 from the inflow pipe.

  In the introduction path 12, the solid mixed liquid 2 flows from the inflow portion 14 through the first detour portion 16 to the second detour portion 17, and then from the second detour portion 17 to the inflow opening 18. Inflows tangential to the surface.

  The solid-mixed liquid 2 that has flowed in the tangential direction of the inner peripheral surface of the inflow opening 18 flows into the conical portion 11 from the inlet while swirling on the inner peripheral surface of the inflow opening 18.

  In the conical portion 11, the solid-containing liquid 2 becomes a swirling flow and flows downward along the taper of the conical portion 11, and is separated into solid and liquid by centrifugal force based on the specific gravity difference.

  Further, the solid separated from the solid-containing liquid 2 is precipitated in the lower part of the conical part 11 and stored in the sludge pot, and the separated liquid 3 from which the solid is separated passes through the inner cylinder part and is separated into a separator. It flows in the axial direction (upward) of the main body 4.

  Further, the separation liquid 3 flows from the inner cylinder portion into the outflow portion 21 as it is, and flows out from the outflow portion 21 through the outflow bypass portion 22 to the outflow pipe.

  In the cyclone separator 1, the inflow portion 14 and the outflow detour portion 22 are connected to each other even if the inflow piping and the outflow piping are installed in a so-called in-line piping path, for example. Since they are arranged in parallel, there is no need to redesign the piping route. That is, since the inflow section 14 can be easily connected to the inflow pipe and the outflow bypass section 22 can be easily connected to the outflow pipe, whether it is a new facility or an existing facility, the cyclone separator 1 can be easily used. Can be installed. For example, a cyclonic separator is easy to maintain because a filter is not required for a filter type separator, but the filter type separator is often installed in an in-line type piping path. When the separator is changed to a conventional cyclone separator, it is necessary to use a design change of a piping route, a joint, or the like. However, the cyclone separator 1 can be easily applied to an inline piping route. .

  In addition, since the introduction path 12 has the inflow portion 14 and the inflow bypass portion 15, the solid mixed liquid 2 that has flowed into the inflow portion 14 from the inflow pipe is smoothly passed through the inflow bypass portion 15 in the tangential direction of the conical portion 11. Therefore, it is difficult to impair the centrifugal force for swirling in the separator body 4 when the solid-containing liquid 2 flows into the separator body 4.

  Further, since the outlet path 13 has the outflow portion 21 and the outflow bypass portion 22, the separation liquid 3 can smoothly flow out in the axial direction from the separator body 4 to the outflow portion 21, and the separation liquid 3 in the separator body 4 can be discharged. The flow is difficult to be disturbed.

  Since the inflow part 14 and the outflow detour part 22 are mutually arranged on the extension line, the connection body 5 is easy to apply to the in-line type piping route.

  In addition, the connecting body 5 is arranged such that the inflow detour portion 15 wraps around the lower portion of the outflow detour portion 22, so that the solid substance mixed liquid 2 is accurately guided in the tangential direction of the separator body 4 by the inflow detour portion 15. It can be designed compactly.

  In the introduction path 12, since the opening area of the inflow detour portion 15 is smaller than the opening area of the inflow section 14, the solid mixed liquid 2 flowing through the introduction path 12 is pressurized due to the difference in the opening area, A turning force is easily applied to the inflowing solid-containing liquid 2.

  In the above-described embodiment, the connection body 5 is configured such that the inflow portion 14 and the outflow detour portion 22 are arranged on an extension line. However, the inflow portion 14 and the outflow detour portion 22 are parallel to each other. If so, it can be appropriately changed.

  In addition, the connecting body 5 is configured such that the inflow detour portion 15 is arranged so as to wrap around the lower portion of the outflow detour portion 22, but the inflow detour portion 15 guides the solid-mixed liquid 2 in the tangential direction of the separator body 4. If the inflow portion 14 and the outflow bypass portion 22 are configured to be parallel to each other, they can be changed as appropriate.

  Although the sludge pot is provided in the lower part of the separator body 4, the present invention is not limited to such a structure. For example, a cover body is provided so as to cover the outside of the separator body 4, and the cover body and the separator are provided. You may make it the structure etc. which were provided with the storage part which stores the solid substances isolate | separated, such as sludge, between the main bodies 4.
