Description

[Technical field]

[0001] The present invention relates to a cyclone-type solid-liquid separation device that separates used coolant (dirty liquid) containing residues (cuttings) discharged from machine tools such as lathes and milling machines into the residues and coolant (clean liquid) for reuse. [Background technology]

[0002] Various devices and means are provided for separating used coolant (dirty liquid) containing residues (cuttings) discharged from machine tools such as lathes and milling machines into the residues and coolant (clean liquid) for reuse. One of these is a cyclone solid-liquid separator (hereinafter referred to as a cyclone solid-liquid separator). This cyclone-type solid-liquid separation device has the characteristics of being simple in structure, small in size, and large in processing capacity, and is therefore used not only for solid-liquid separation of coolant used in machine tools, but also for a variety of applications in many fields such as particle classification, concentration, and collection. The solid to be separated is the "target," the liquid that contains the target solid is the "transport fluid," and the mixture of the target and transport fluid is the solid-liquid mixture. Various techniques have been disclosed for improving separation performance by making improvements to the collection section of the target material, which is usually located below the cyclone solid-liquid separator.

[0003] For example, Patent Document 1 aims to provide a cyclone that can collect single micron particles with high collection efficiency. As a solution, it includes a cyclone body 4 having a cylindrical upper barrel 4a and an inverted conical lower barrel 4b, an inlet 8 for introducing raw materials and fluids, a top plate 4c that covers the upper edge of the upper barrel and has an opening 12 at the center, a first discharge port 10 that is inserted into the opening along the vertical central axis of the upper barrel and raises the fine powder and fluid separated from the raw materials and fluids by the swirling motion and discharges them from the cyclone body, a second discharge port 4f that discharges the coarse powder and fluid obtained by the swirling motion from the lower end of the lower barrel, a collection box 6 connected to the lower part of the second discharge port for collecting the coarse powder and fluid, and an underflow mechanism 7 for underflowing the coarse powder and fluid from the collection box. A cyclone device 2 is disclosed in which a cavity 16 having a substantially truncated cone shape with the upper end connected to the second discharge port and spreading downward is formed at the upper part of the collection box.

[0004] Also, Patent Document 2 aims to provide a solid-liquid separation device that can improve the separation efficiency of solids while saving space. As a solution, it includes a centrifuge 3 having a slurry discharge pipe 5 at the lower part for swirling and centrifugally separating raw water containing solids and discharging the slurry containing solids to the outside, and a treated water discharge pipe 7 at the upper part for discharging the treated water to the outside; a raw water tank 2 for storing the raw water; a water pump P1 for pumping the raw water in the raw water tank to the centrifuge; recovery pots 6, 6A, 6B into which the slurry discharge pipe of the centrifuge is inserted and where the solids contained in the slurry discharged from the slurry discharge pipe settle in the form of sludge; a supernatant discharge pipe inserted into the upper part of the recovery pot for discharging the supernatant water of the slurry in the recovery pot; and a sludge discharge pipe 8 for discharging the sludge that has settled at the lower part of the recovery pot. A solid-liquid separation device is disclosed in which a gap is provided between the lower end 5e of the slurry discharge pipe and the bottom 6b of the recovery pot, and the lower end 5e of the slurry discharge pipe is located at a lower position than the lower end 7e of the supernatant discharge pipe.

[0005] However, when the solid-liquid mixture is not pressurized and transported to form a swirling flow generating an appropriate centrifugal force, the cyclone solid-liquid separation device cannot effectively separate the target material from the transport fluid, even when combined with the above-mentioned prior art, and the solid-liquid mixture ends up being deposited in the target material collection area. This problem cannot be solved. Examples of situations in which the solid-liquid mixture is not pressurized and pumped to form a swirling flow and generate an appropriate centrifugal force include immediately after the cyclone solid-liquid separation device is started, and when pressurized pumping of the solid-liquid mixture has ended. Furthermore, as shown in FIG. 9, conventionally, a removable collection container has been provided at the collection section of the target object, and when the target object and solid-liquid mixture settle in the collection container, the collection container is appropriately removed and another (new) storage container is installed. Alternatively, a complex discharge mechanism such as a conveyor device has been connected below the cyclone-type solid-liquid separator, and the falling target object and solid-liquid mixture are discharged.

[0006] Therefore, in Patent No. 7366437, the inventors of the present application set out to provide a cyclone-type solid-liquid separation device that reduces the environmental load and enables smooth solid-liquid separation in a space-saving manner and with a simple discharge mechanism without increasing the number of parts or the size of the device, and enables highly efficient recovery of the target product.The inventors disclosed a cyclone-type solid-liquid separation device that includes a main body that supplies dirty liquid containing residues into the device at a predetermined pressure and performs solid-liquid separation by a swirling flow, and a residue storage and discharge mechanism that is connected to the lower end of the main body and discharges the residues that have settled in a second storage section and some of the dirty liquid by sliding a piston horizontally (Patent Document 3).

[0007] [Patent Document 1] JP 2016-41398 A [Patent Document 2] JP 2015-205278 A [Patent Document 3] Patent No. 7366437 Summary of the Invention [Problem to be solved by the invention]

[0008] However, Patent Document 3 makes it possible to perform smooth solid-liquid separation in a space-saving manner and to recover the target product with high efficiency. However, the present invention aims to solve the problem of liquid leakage caused by a configuration that requires a long sliding distance to discharge the residue and some of the dirty liquid, and to provide a space-saving cyclone-type solid-liquid separator with a simpler configuration and a method for storing and discharging residue in a cyclone-type solid-liquid separator. [Means for solving the problem]

[0009] The cyclone-type solid-liquid separation device of the present invention comprises a supply port for supplying dirty liquid containing residue discharged from a machine tool such as a lathe or milling machine at a predetermined pressure into the device, a clean liquid discharge port for discharging clean liquid separated from the residue by a swirling flow generated inside, and a main body provided with a residue discharge port at the lower end for discharging the residue and a portion of the dirty liquid, a first storage section which is a tubular body communicating with the residue discharge port, a second storage section which is a residue storage body having holes therein, and a The residue storage and discharge mechanism is characterized in that it changes its form between a storage form in which the first storage portion and the second storage portion form a single continuous hole, and a discharge form in which the first storage portion and the second storage portion are separated from each other from the storage form to form a bottom surface of the first storage portion and to discharge only the residue deposited in the second storage portion and some of the dirty liquid.

[0010] The residue storage and discharge mechanism constituting the cyclone-type solid-liquid separation device of the present invention is characterized in that when changing its form from a storage form in which the first storage section and the second storage section have a single continuous hole shape to a discharge form in which the residue storage body is rotated while enclosed in an outer shell to discharge the residue deposited in the second storage section and some of the dirty liquid, in the discharge form, the portion of the residue storage body that is not perforated in the second storage section forms the bottom portion of the first storage section and separates the first storage section and the second storage section.

[0011] The residue container of the present invention is cylindrical, and is arranged so that the line connecting the centers of the two circular bottom surfaces is horizontal, and a second container section is drilled into the side surface. The container is characterized in that its shape can be changed between a container form and a discharge form by rotating the container 180° around the axis of the line connecting the centers of the two circular bottom surfaces.

[0012] On the other hand, the residue container of the present invention may be spherical, with a second container section drilled into its surface, and its shape can be changed between a container form and a discharge form by rotating the container 180° around a horizontal line passing through the center of the sphere. By using the residue container of the present invention, the direction in which the residue is stored and the direction in which it is discharged are vertical and on the same line, so that the operating range of the device can be made smaller than in conventional inventions, thereby preventing liquid leakage and saving space. Effect of the Invention

[0013] Here, in the case of a mechanism for discharging residue by sliding a piston or a second layer plate equipped with a second storage section as disclosed in Patent No. 7366437, the inventors of the present application discovered the effectiveness of the present invention after finding in demonstration experiments that sliding caused residue to become caught and damage to the sealing members (such as gaskets) used to prevent liquid leakage. Furthermore, it has been found that the energy required to rotate the residue container 180° as in the present invention can be made smaller than the energy required to slide the second container. As described above, according to the present invention, it is possible to provide a cyclone-type solid-liquid separation device and a residue collection and discharge method that eliminate the need for recovery containers that require replacement and complex devices for discharging residue, thereby reducing the burden on the environment, and that enables space-saving, highly efficient solid-liquid separation and smooth recovery and disposal of residue without increasing the number of parts or the size of the device thanks to a simple residue collection and discharge mechanism.

[0015] (First embodiment) DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, in which: FIG.

[0016] (Cyclone type solid-liquid separator) FIG. 1 is a perspective view that shows a schematic diagram of a cyclone type solid-liquid separator 1 according to a first embodiment of the present invention, and FIG. 2 is a front sectional view of the cyclone type solid-liquid separator 1. As shown in FIG. The main body 10 has a cylindrical upper lid at its upper part U, a funnel shape with an inner diameter decreasing downward at its central part M, and a tube shape with an opening O at its lower end. The inside of the central part M of the main body 10 is also generally funnel-shaped like the outside, and on its upper side is a supply port 100a for supplying a solid-liquid mixture (here, dirty liquid L1) containing a target material (here, residue X) discharged after being used as a coolant in a machine tool such as a lathe or milling machine to the inside of the main body 10, and in the center of the upper part U is a clean liquid discharge port 100b for discharging a carrier fluid (here, clean liquid Lc) separated from the residue X. The opening O at the lower end of the main body 10 serves as a residue discharge port 100c for discharging the residue X separated from the dirty liquid L1. In the cyclone-type solid-liquid separation device 1 according to this embodiment, when dirty liquid L1 mixed with residue X is flowed into the main body 10 from the supply port 100a by a pressurizing means such as a pump, a swirling flow (cyclone) is generated, and the dirty liquid L1 is separated into clean liquid Lc and residue X due to the difference in mass (specific gravity) between the liquid and solid, and the clean liquid is discharged from the clean liquid discharge port 100b, while the residue X is discharged from the residue discharge port 100c. The main body 10 may be a known device, and the capacity of the main body 10, the supply rate of the dirty liquid L1, etc. can be appropriately selected.

[0017] (Outline of the residue storage and discharge mechanism) A residue storage and discharge mechanism 20 is continuously provided below the residue discharge port 100c through which the residue X separated by the main body 10 of the cyclone type solid-liquid separation device 1 is discharged. As shown in FIGS. 3 and 4 which is a cross-sectional view thereof, the residue storage and discharge mechanism 20 in the present embodiment includes a joint 200a which is a tubular body communicating with the lower end of the main body 10 of the cyclone type solid-liquid separation device, a residue storage body 200b disposed below the joint 200a, and an outer shell 200c that horizontally rotatably encloses the residue storage body 200b. The joint 200a constituting the residue storage and discharge mechanism 20 has an opening with a size corresponding to the inner diameter of the residue discharge port 100c which is the lower end of the main body 10, and is a tubular body that is connected and extends vertically downward. It is preferably in a substantially conical shape in which the inner diameter gradually increases from above the joint (the side connected to the residue discharge port 100c) downward (toward the residue storage body 200b and the outer shell 200c). This is to suppress the adhesion of the residue X to the inner wall of the joint 200a. Here, the space formed inside the joint 200a is defined as the first storage portion H1 (see FIG. 4). Next, the residue storage body 200b constituting the residue storage and discharge mechanism 20 is shown in FIG. 5, where (a) is a perspective view and (b) is a perspective view. The residue storage body 200b is cylindrical and is disposed below the joint 200a such that the line A1 connecting the centers of the two circles which are the bottom surfaces is horizontal. A hole is formed on its side surface corresponding to the inner diameter of the lower end of the joint 200a and gradually decreasing in inner diameter vertically downward. This hole (the space formed thereby) is defined as the second storage portion H2 (see FIGS. 4 and 5). The state in which the first storage portion H1 and the second storage portion H2 form a continuous storage recess H is defined as the storage form. As shown in FIG. 6, with the cylindrical residue storage body 200b enclosed within the outer shell 200c, the residue storage body 200b is rotated 180° about a line connecting the centers of the two circles that form the bottom surface of the residue storage body 200b as a rotation axis A1, whereby the residue X deposited in the second storage section H2 is discharged vertically (into a residue collection container D arranged therein). This is the discharge mode. At this time (in the discharge mode), the side surface of the portion of the residue storage body 200b where the second storage section H2 is not pierced forms the bottom of the first storage section H1, so that the first storage section H1 and the second storage section H2 are separated and the internal pressure of the main body section 10 of the cyclone-type solid-liquid separation device 1 is maintained, allowing solid-liquid separation to continue even when the residue is being discharged. An O-ring is provided in the residue container 200b to ensure close contact with the outer shell 200c and prevent leakage or infiltration of the contaminated liquid L1 (see Figures 5 and 6), and the liquid leakage prevention means can be appropriately selected from known technologies. The outer shell 200c constituting the residue storage and discharge mechanism 20 is a cylindrical member that contains the residue storage body 200b rotatably around its central axis, and is connected to the lower end of the joint 200a. On its side, it has an inlet E1 that corresponds to the inner diameter of the lower end of the joint 200a (first storage section H1) and a discharge outlet E2 located opposite the inlet E1. In the storage configuration, the outer shell 200c is shaped so as not to prevent the residue X from being stored in the second storage section H2, and in the discharge configuration, it is shaped so as not to prevent the discharge of the residue X (see FIG. 7). Here, the transition between the storage form and the discharge form, that is, the rotation of the residue storage body 200b, may be performed manually or automatically under electrical control, and the power and rotation means thereof can be appropriately selected.

[0018] (Effect of residue collection and discharge mechanism) Immediately after the cyclone-type solid-liquid separation device 1 is started, the dirty liquid L1 is supplied under pressure from the supply port 100a into the inside of the main body 10, but until a sufficient swirling flow is generated, part of the dirty liquid L1 falls downward (vertically) from the main body 10 without promoting solid-liquid separation, and is captured in the storage recess H that is stored in the residue storage and discharge mechanism 20. Next, when an appropriate swirling flow is generated inside the main body 10 to promote the solid-liquid separation of the dirty liquid L1, only the residue X settles and is accommodated in the accommodation recess H, and the clean liquid Lc is discharged from the clean liquid discharge port 100b, returned to the machine tool, and reused as a coolant (see Fig. 1). Here, in the accommodation recess H, due to the difference in mass (specific gravity), the residue X, which is solid and is a powder of minerals or metals, is deposited in the second accommodation portion H2 formed in the residue container 200b, and most of the liquid accumulates in the upper first accommodation portion H1 formed in the joint 200a (see Fig. 4). Then, when the residue X deposited in the accommodation recess H reaches a predetermined amount, the residue container 200b is rotated 180°, and the residue X accommodated in the second accommodation portion H2 is discharged. Here, by rotating the residue container 200b 180° with the line passing through the centers of the two circles, which is the bottom surface of the cylindrical (residue container 200b), as the rotation axis A1, the side surface portion of the residue container 200b where the accommodation portion H2 is not formed forms the bottom surface portion of the first accommodation portion H1 formed in the joint 200a (see Fig. 8). By adopting the residue accommodation and discharge mechanism 20 of the present embodiment, even in the scene where the residue container 200b is rotated to discharge the residue X, a part of the dirty liquid L1 and the residue X remains in the first accommodation portion H1 without being discharged, so that the residue can be discharged without changing the pressure inside the main body 10. That is, even while the swirling flow is generated and the solid-liquid separation is being performed, the residue X can be discharged without degrading the working efficiency and working accuracy.

[0019] Also, different from the cyclone type solid-liquid separation device disclosed in Japanese Patent No. 7366437 by the inventor of the present application, as a feature of the cyclone type solid-liquid separation device in the present embodiment, the accommodation direction and the discharge direction of the residue X are the same and on the same line. Thus, the operation range of the residue container 200b in the residue accommodation and discharge mechanism 20 in the present embodiment is small, the possibility of liquid leakage can be suppressed, and the space-saving of the installation space of the device can be realized. Furthermore, since the residue X, which is a solid with a high specific gravity, is accommodated in the lower part of the accommodation recess H and the contaminated liquid L1, which is a liquid with a low specific gravity, is accommodated in the upper part, it is possible to suppress the amount of the contaminated liquid L1 discharged together with the residue X and to efficiently discharge the residue X. It is preferable that the amount of the residue X deposited reaches the first accommodation portion H1, and the joint 200a may be made of a transparent material so that it can be visually observed (see FIG. 9). Since the amount of contaminated liquid L1 discharged together with the residue X is small, reprocessing of the residue is also facilitated. Here, the amount of residue X deposited in the accommodating recess H can be grasped by appropriately selecting from among known methods (not shown), such as time measurement based on past performance or measurement of the amount of residue in the accommodating recess H using a sensor. Furthermore, when the supply of the dirty liquid L1 into the main body 10 is terminated, as is the case when the device is started up, a sufficient swirling flow is not obtained, so the dirty liquid L1 does not separate into solid and liquid and falls downwardly from the main body 10, where it is captured in the storage recess H, which is in the storage form.

[0020] (Regarding the shape of the storage compartment) The second storage section H2 of the residue storage body 200b in the present embodiment is desirably shaped so that the inner diameter gradually decreases downward from the opening in the storage state (see FIG. 5). This is because, when the residue storage / discharge mechanism 20 discharges the residue X and dirty liquid L1 deposited in the second storage section H2 in the storage form in the discharge form, the residue storage body 200b rotates 180° around its axis, so that it is turned upside down as shown in FIG. 10, and the second storage section H2 takes on a shape in which the inner diameter gradually decreases from the lower opening. This is expected to prevent the residue X from adhering and remaining there, and to have the effect of discharging all of the residue X from the second storage section H2. In this embodiment, the size of the opening of the second accommodating portion H2 corresponds to the size of the lower opening of the joint 200 (first accommodating portion H1), but the size of the opening of the second accommodating portion H2 may be greater than the size of the lower opening of the joint 200. This is because if the opening of the second storage section H2 is smaller than the lower opening of the joint 200, the residue X may accumulate near the opening, which may hinder efficient residue collection and axial rotation of the residue storage body 200b.

[0021] Second Embodiment The second embodiment of the present invention will be described in detail below with reference to the drawings which specifically show the same.

[0022] (Cyclone type solid-liquid separator) Fig. 11 is a perspective view showing a cyclone type solid-liquid separator 2 according to a second embodiment of the present invention, and Fig. 12 is a front cross-sectional view. The configuration of the main body 10 and the method of solid-liquid separation are similar to those of the first embodiment, so detailed explanations will be omitted.

[0023] (Outline of the residue collection and discharge mechanism) A residue receiving and discharging mechanism 21 is provided below an opening O at the bottom end of the main body 10 of the cyclone-type solid-liquid separator 2 for receiving the residue X separated by the main body 10. As shown in FIG. 13, the residue collection and discharge mechanism 21 in this embodiment is composed of a joint 210a which is a tubular body communicating with an opening O at the lower end of the main body 10, a spherical residue collection body 210b arranged below the joint 210a, and an outer shell 210c which contains the residue collection body 210b in a rotatable state. The joint 210a constituting the residue collection and discharge mechanism 21 has an opening of a size corresponding to the inner diameter of the opening O at the lower end of the main body 10, is a tubular body that is connected and extends vertically downward, and preferably has a generally conical shape with an inner diameter that gradually increases from the top to the bottom of the joint. This is to prevent the residue X from adhering to the inner wall of the joint 210a. Here, the space formed inside the joint 210a is referred to as a first housing portion H1 (see FIG. 14). Next, the residue storage body 210b constituting the residue collection and discharge mechanism 21 is shown in Figure 15. The residue storage body 210b is arranged below the joint 210a in a spherical shape, and a hole is drilled in its surface so that the hole corresponds to the inner diameter of the lower end of the joint 210a and the inner diameter gradually decreases vertically downward. This hole (the space formed by the hole) is the second storage section H2. The state in which the first storage section H1 and the second storage section H2 form one continuous storage recess H is called the storage form (see Figure 14). Then, as shown in FIG. 15, the spherical residue storage body 210b is rotated 180° about a horizontal line passing through the center of the spherical residue storage body 21 as a rotation axis A2 so that the opening of the second storage section H2 arranged at the top in the storage form faces vertically while being enclosed within the outer shell 210c (see FIG. 15(a)). In this manner, the state in which the residue X deposited in the second storage section H2 is discharged into the residue recovery container D arranged in the vertical direction of the residue collection and discharge mechanism 21 is referred to as a discharge mode. Here, the residue container 210b of this embodiment is provided with a handle Y for transitioning between the container form and the discharge form, i.e., for rotating the residue container 210b, but the method for rotating the residue container 210b and its shape can be appropriately selected from known technologies. The outer shell 210c constituting the residue storage and discharge mechanism 21 is a member that rotatably contains the residue storage body 210b, and is connected to the lower end of the joint 210a, and is provided with an inlet E1 above it that corresponds to the inner diameter of the lower end of the joint 210a (first storage section H1) and a discharge outlet E2 at a position opposite the inlet E1.In the storage configuration, it does not hinder the storage of the residue X into the second storage section H2, and in the discharge configuration, it is shaped so as not to hinder the discharge of the residue X from the residue storage body 200b (see Figure 15). The liquid leakage prevention means can be appropriately selected from known technologies, such as arranging an O-ring on the outer shell 210c to ensure close contact with the residue container 210b and prevent leakage or infiltration of the contaminated liquid L1 (not shown).

[0024] (Effect of residue collection and discharge mechanism) By adopting the residue storage and discharge mechanism 21 of this embodiment, as in the first embodiment described above, the first storage section H1 and the second storage section H2 are separated, and the residue can be discharged without changing the pressure inside the main body section 10. Therefore, even when a swirling flow is generated and solid-liquid separation is occurring, the residue X can be discharged without reducing the work efficiency or work accuracy. Furthermore, since the residue collection and discharge mechanism 21 has a small operating range for the residue collection body 210b, the possibility of liquid leakage is reduced, and the space required for installing the device can be reduced.

[0025] (Shape of outer shell) In the first and second embodiments, the shape of the outer shell (200c, 210c) in the present invention corresponds to the shape of the respective residue containers, but as long as it rotatably contains the residue container, the shape is not particularly important, and the shell may be formed to have a rectangular parallelepiped or cubic appearance, as shown in Fig. 16. By having a rectangular parallelepiped or cubic appearance, the connection portion with the joint 200a (210a) can be made flat, which facilitates the connection structure and has the effect of suppressing liquid leakage.

[0026] As described above, the cyclone type solid-liquid separator (1, 2) and the residue collection and discharge mechanism (20, 21) and residue collection and discharge method in the cyclone type solid-liquid separator of the present invention can be adopted in various types of cyclone type solid-liquid separators, and do not require complex residue discharge devices such as containers or conveyor devices, thereby reducing the environmental load and contributing to space-saving and highly efficient solid-liquid separation.
