Description

[Technical Field]

[0001] This invention relates to a cyclone-type solid-liquid separator that separates used coolant (dirty liquid) containing residues (chips) 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 available for separating used coolant (dirty liquid) containing residues (chips) 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 solid-liquid separator is characterized by its simple structure, small size, and high processing capacity. Therefore, it is not only used 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 containing 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 devising an approach that involves improving the collection section of the target material, which is usually located below the cyclone solid-liquid separator.

[0003] For example, Patent Document 1 describes an object of providing a cyclone that can collect single-micron particles with high collection efficiency, and as a means for solving this problem, it describes a cyclone body 4 having a cylindrical upper barrel 4a and an inverted cone-shaped lower barrel 4b, an inlet 8 for introducing raw material and fluid, a top plate 4c that covers the upper edge of the upper barrel and has an opening 12 in the center, and a top plate 4c that is inserted into the opening along the vertical center axis of the upper barrel and that causes the fine powder and fluid separated from the raw material and fluid to rise due to the swirling motion of the raw material and fluid. The cyclone device (2) is provided with a first discharge outlet (10) for discharging from the cyclone body, a second discharge outlet (4f) for discharging coarse particles 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 outlet and collecting the coarse particles and fluid, and an underflow mechanism (7) for causing the coarse particles and fluid to underflow from the collection box, and the cyclone device disclosed has a cavity (16) formed in the upper part of the collection box, the upper end of which is connected to the second discharge outlet and which has a generally truncated conical shape that widens downward.

[0004] Furthermore, Patent Document 2 addresses the issue of providing a solid-liquid separation device that can improve the separation efficiency of solids while saving space, and as a means of solving this issue, it discloses a centrifuge 3 that has a slurry discharge pipe 5 at its bottom for swirling and centrifuging raw water containing solids and discharging a slurry containing solids to the outside, and a treated water discharge pipe 7 at its top for discharging treated water to the outside; a raw water tank 2 for storing raw water; a water pump P1 for pressure-feeding the raw water from the raw water tank to the centrifuge; collection pots 6, 6A, 6B into which the slurry discharge pipe of the centrifuge is inserted and into which solids contained in the slurry discharged from the slurry discharge pipe are allowed to settle in the form of sludge; a supernatant discharge pipe inserted into the top of the collection pot for discharging supernatant water of the slurry in the collection pot; and a sludge discharge pipe 8 for discharging the sludge that has settled to the bottom of the collection 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 lower 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 that generates an appropriate centrifugal force, the cyclone solid-liquid separator does not adequately separate the target material from the transport fluid, even when combined with the above-mentioned prior art, and the problem of the solid-liquid mixture remaining as it is and settling in the target material collection area 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 separator is started, and when the pressurized pumping of the solid-liquid mixture has ended. Furthermore, as shown in Figure 9, conventionally, a removable collection container has been provided at the collection section of the target material, and when the target material and solid-liquid mixture settle in the collection container, the collection container is removed as appropriate and another (new) storage container is installed. Alternatively, a complex discharge mechanism such as a conveyor device has been connected below the cyclone solid-liquid separator, and the falling target material 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 separator that reduces the environmental impact and that enables smooth solid-liquid separation in a space-saving manner and highly efficient recovery of the target material using a simple discharge mechanism without increasing the number of parts or the size of the device, and disclosed a cyclone-type solid-liquid separator that includes a main body that supplies dirty liquid containing residues into the device at a predetermined pressure and performs solid-liquid separation by swirling flow, and a residue collection and discharge mechanism that is connected to the bottom end of the main body and discharges the residues and some of the dirty liquid that have settled in a second storage section by sliding a piston horizontally (Patent Document 3). [Prior art documents] [Patent documents]

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

[0008] However, Patent Document 3 has made it possible to carry out smooth solid-liquid separation in a space-saving manner and to recover the target product with high efficiency. However, it also solves the problem of liquid leakage caused by the configuration that requires a long sliding distance to discharge the residue and some of the dirty liquid, and provides a space-saving cyclone-type solid-liquid separator with an even simpler configuration. [Means for solving the problem]

[0009] The cyclone-type solid-liquid separator of the present invention comprises a supply port for supplying dirty liquid containing residue discharged from machine tools such as lathes and milling machines 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, a main body having a residue discharge port at the bottom for discharging the residue and a portion of the dirty liquid, a first container which is a tubular body communicating with the residue discharge port, and a second container which contains a residue container having holes. The device is also equipped with a residue collection and discharge mechanism composed of an outer shell having an opening that does not hinder the collection and discharge of residue, and the residue collection and discharge mechanism is characterized by changing its form between a storage form in which the first storage section and the second storage section form a single continuous hole, and a discharge form in which the first storage section and the second storage section are separated from each other from the storage form to form the bottom surface of the first storage section and to discharge only the residue deposited in the second storage section and some of the contaminated liquid.

[0010] The residue collection 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 and some of the dirty liquid deposited in the second storage section, in the discharge form, the portion of the residue storage body that is not perforated by the second storage section forms the bottom portion of the first storage section and separates the first storage section from the second storage section.

[0011] The residue container of this invention is cylindrical, with the line connecting the centers of the two circular bottom surfaces horizontal, and a second container section drilled into the side.The container can be rotated 180 degrees around the axis connecting the centers of the two circular bottom surfaces, allowing it to change shape between a storage form and a discharge form.

[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 it 180 degrees around a horizontal line passing through the center of the sphere. By using the residue container of this invention, the direction of residue collection and discharge are vertical and on the same line, which makes it possible to reduce the operating range of the device compared to conventional designs, thereby reducing liquid leakage and saving space. [Effects of the Invention]

[0013] In the case of the 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 application's device after finding in demonstration experiments that sliding caused residue to become trapped and damage to the sealing material (such as a gasket) used to prevent liquid leakage. Furthermore, it was discovered 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, the present invention eliminates the need for replaceable collection containers and complex residue discharge devices, thereby reducing the environmental impact. It also provides a cyclone-type solid-liquid separation device and a residue collection and discharge method that allows for space-saving, highly efficient solid-liquid separation without increasing the number of parts or size of the device, and allows for smooth residue collection and disposal.

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

[0016] (Cyclone type solid-liquid separator) FIG. 1 is a perspective view showing a cyclone type solid-liquid separator 1 according to a first embodiment of the present invention, and FIG. 2 is a front cross-sectional view of the cyclone type solid-liquid separator 1. As shown in FIG. The main body 10 has an upper portion U that is a cylindrical top cover, and a central portion M that is funnel-shaped with an inner diameter that decreases downward and has a tubular shape with an opening O at its lower end. The interior of the central portion M of the main body 10 is also generally funnel-shaped, just like the exterior. The upper side of the central portion M is provided with a supply port 100a that supplies a solid-liquid mixture (herein referred to as contaminated liquid L1) containing a target substance (herein referred to as residue X) that is discharged after being used as a coolant in a machine tool such as a lathe or milling machine. The central portion U is provided with a clean liquid discharge port 100b that discharges a carrier fluid (herein referred to as clean liquid Lc) that has been separated from the residue X. The opening O at the bottom of the main body 10 serves as a residue discharge port 100c that discharges the residue X separated from the contaminated liquid L1. In the cyclone solid-liquid separator 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 the 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 contaminated liquid L1, etc. can be selected appropriately.

[0017] (Outline of residue collection and discharge mechanism) A residue collection and discharge mechanism 20 is provided below the residue discharge port 100c through which the residue X separated by the main body 10 of the cyclone solid-liquid separator 1 is discharged. As shown in FIG. 3 and its cross-sectional view in FIG. 4, the residue collection and discharge mechanism 20 in this embodiment is composed of a joint 200a, which is a tubular body communicating with the lower end of the main body 10 of the cyclone solid-liquid separator, a residue collection body 200b arranged below the joint 200a, and an outer shell 200c that contains the residue collection body 200b in a state where it can rotate horizontally around its axis. The joint 200a constituting the residue collection and discharge mechanism 20 is a tubular body that extends vertically downward and has an opening of a size corresponding to the inner diameter of the residue discharge outlet 100c at the bottom of the main body 10. The joint 200a preferably has a generally conical shape with an inner diameter that gradually increases from the top of the joint (the side connected to the residue discharge outlet 100c) to the bottom (toward the residue collection body 200b and outer shell 200c). This is to prevent the residue X from adhering to the inner wall of the joint 200a. Here, the space formed inside the joint 200a is referred to as a first housing portion H1 (see FIG. 4). Next, the residue storage body 200b constituting the residue collection and discharge mechanism 20 is shown in Figure 5, where (a) is a perspective view and (b) is a see-through view. The residue storage body 200b is cylindrical and located below the joint 200a, with the line A1 connecting the centers of the two circles that form the bottom surface horizontal. A hole is drilled in the side surface of the residue storage body 200b, corresponding to the inner diameter of the lower end of the joint 200a and gradually decreasing in diameter vertically downward. This hole (the space formed by it) is referred to as the second storage section H2 (see Figures 4 and 5). The state in which the first storage section H1 and the second storage section H2 form a single continuous storage recess H is referred to as the storage configuration. As shown in FIG. 6, the cylindrical residue storage body 200b is enclosed in the outer shell 200c, and is then rotated 180° around the rotation axis A1, which is the line connecting the centers of the two circles that form the bottom surface of the residue storage body 200b, to discharge the residue X deposited in the second storage section H2 vertically (into the residue collection container D arranged therein). This constitutes 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 perforated forms the bottom of the first storage section H1, so the first storage section H1 and the second storage section H2 are separated, the internal pressure of the main body section 10 of the cyclone solid-liquid separator 1 is maintained, and solid-liquid separation can 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 selected from known technologies as appropriate. The outer shell 200c constituting the residue collection and discharge mechanism 20 is a cylindrical member that contains the residue collection 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 an outlet E2 located opposite the inlet E1. In the storage configuration, the outer shell 200c is shaped so that the residue X does not interfere with collection into the second storage section H2, and in the discharge configuration, the outer shell 200c does not interfere with discharge of the residue X (see FIG. 7). Here, the transition between the storage mode and the discharge mode, 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 can be selected appropriately.

[0018] (Effect of residue collection and discharge mechanism) Immediately after starting the cyclone-type solid-liquid separation device 1, 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 and solid-liquid separation of the dirty liquid L1 is promoted, only the residue X settles and is stored in the storage recess H, and the clean liquid Lc is discharged from the clean liquid discharge port 100b, returned to the machine tool, and reused as coolant (see Figure 1). Here, within the storage recess H, due to differences in mass (specific gravity), the solid residue X, which is a powder of minerals or metals, settles in the second storage section H2 formed in the residue storage body 200b, while most of the liquid accumulates in the upper first storage section H1 formed in the joint 200a (see Figure 4). When the amount of residue X deposited in the storage recess H reaches a predetermined amount, the residue storage body 200b is rotated 180° to discharge the residue X stored in the second storage section H2. Here, by rotating the residue storage body 200b 180° around the rotation axis A1, which is a line passing through the centers of the two circles that form the bottom surface of the cylindrical (residue storage body 200b), the side portion of the residue storage body 200b where the storage section H2 is not formed forms the bottom portion of the first storage section H1 formed in the joint 200a (see FIG. 8). By employing the residue collection and discharge mechanism 20 of this embodiment, even when the residue container 200b is rotated to discharge the residue X, the contaminated liquid L1 and a portion of the residue X remain in the first container H1 without being discharged, so that the residue can be discharged without changing the pressure inside the main body 10. In other words, even when a swirling flow is generated and solid-liquid separation is being performed, the residue X can be discharged without reducing work efficiency or work accuracy.

[0019] Furthermore, unlike the cyclone-type solid-liquid separator previously disclosed by the inventor of the present application in Japanese Patent No. 7366437, the cyclone-type solid-liquid separator of this embodiment is characterized in that the direction in which the residue X is received and the direction in which it is discharged are the same and on the same line. This reduces the operating range of the residue receiving and discharging mechanism 20 of this embodiment for the residue receiving body 200b, thereby reducing the possibility of liquid leakage and enabling space saving for installing the apparatus. 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 contaminated liquid L1 discharged together with the residue X and efficiently discharge the residue X. It is preferable that the amount of deposited residue X reaches the first accommodation portion H1, and the joint 200a may be made of a transparent material so that it can be visually confirmed (see FIG. 9). Since the amount of contaminated liquid L1 discharged together with the residue X is small, reprocessing of the residue becomes easy. Here, the amount of residue X deposited in the storage recess H can be determined by any known method, such as measuring the amount of residue X over time based on past performance or measuring the amount of residue in the storage recess H using a sensor (not shown). Furthermore, when the supply of the dirty liquid L1 into the main body 10 is completed, as is the case when the device is started up, sufficient swirling flow is not obtained, so the dirty liquid L1 does not undergo solid-liquid separation and falls downwards in 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 this embodiment is preferably shaped so that the inner diameter gradually decreases downward from the opening in the storage state (see FIG. 5). This is a residue containment discharge When the mechanism 20 discharges the residue X and dirty liquid L1 deposited in the second storage section H2 in the storage mode in the discharge mode, the residue storage body 200b rotates 180° around its axis, turning it upside down as shown in Figure 10, and the second storage section H2 takes on a shape in which the inner diameter gradually decreases from the lower opening, which is expected to prevent the residue X from adhering and remaining, and to discharge all of the residue X in the second storage section H2. In this embodiment, the size of the opening of the second storage section H2 corresponds to the size of the lower opening of the joint 200 (first storage section H1), but the size of the opening of the second storage section 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 accompanying drawings.

[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 the same as those in the first embodiment, so detailed explanations will be omitted.

[0023] (Outline of residue collection and discharge mechanism) A residue collection and discharge mechanism 21 is provided below an opening O at the bottom end of the main body 10 of the cyclone solid-liquid separator 2, for receiving the residue X separated by the main body 10. As shown in Figure 13, the residue collection and discharge mechanism 21 in this embodiment is composed of a joint 210a, which is a tubular body that communicates with the 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 that rotatably contains the residue collection body 210b. 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 bottom 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, in order 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 section 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 its inner diameter corresponds to the inner diameter of the lower end of the joint 210a and gradually decreases vertically downward. This hole (the space formed by it) is referred to as the second storage section H2. The state in which the first storage section H1 and the second storage section H2 form a single continuous storage recess H is referred to as the storage configuration (see Figure 14). Then, as shown in Figure 15, the spherical residue storage body 210b is rotated 180 degrees around 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, which is arranged above in the storage form, faces vertically while being enclosed in the outer shell 210c (see Figure 15(a)). In this way, 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 called a discharge mode. Here, the residue container 210b of this embodiment is provided with a handle Y for transitioning between the storage 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. Above it, it has an inlet E1 that corresponds to the inner diameter of the lower end of the joint 210a (first storage section H1), and an outlet E2 located 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 does not 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 (not shown), 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.

[0024] (Effect of residue collection and discharge mechanism) By adopting the residue collection 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 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, it is possible to reduce the possibility of liquid leakage and also to achieve space saving for installing the device.

[0025] (Shape of outer shell) In the first and second embodiments, the shapes of the outer shells (200c, 210c) of the present invention correspond to the shapes of the respective residue containers, but as long as they rotatably contain the residue containers, any shape is acceptable, and they may be formed so that their appearance is rectangular or cubic, as shown in Fig. 16. By forming the outer shells into a rectangular or cubic shape, the connection portion with the joint 200a (210a) can be made flat, which simplifies the connection structure and also has the effect of suppressing liquid leakage.

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