Description

  The present invention separates the floating oil from the normal oil by utilizing the specific gravity difference between the floating oil and the normal oil contained in the circulating machining fluid and the natural kinetic energy such as the flow force and drop force of the circulating machining fluid. -It relates to a floating oil separation and recovery device to be recovered.

  The circulating fluid used in conventional machine tool processing is once recovered in a storage tank provided inside or outside the machine tool, and the floating oil content including lubricating oil, scum, sludge, etc. mixed during the cutting process. Is recovered by various recovery means such as a float type, a mechanical type, a bellows suction type, a screw type, a belt type, an overflow type, and a fine bubble generation type.

  In the float type and bellows suction type recovery means, the submersible pump and the circulation pump are installed in the same storage tank, so the suction port of the submersible pump corresponding to the vertical fluctuation of the liquid level is secured at the liquid level. A floating device that needs to have a structure that requires a recovery device on the liquid surface that becomes unstable due to the generation of ripples by the circulation pump. Since the fluid flows in from all directions of the suction port of the submersible pump, the direction of the fluid force that flows into the suction port of the submersible pump and the direction of the fluid force of the liquid level by the circulation pump partially cancel each other. At the same time, there was a problem that the floating oil was not efficiently recovered unless a shifting device or the like was provided. Also, in the mechanical recovery means, the provision of the recovery device makes the structure complicated, so that the device becomes expensive, maintenance is also required, and the upper surface of the storage tank is blocked by the recovery device. There were many problems such as. Furthermore, in the screw type and belt type recovery means, there is a problem that the collection area of the floating oil is extremely narrow, and in the overflow type and fine bubble generation type recovery means, the floating oil component gets over the partition plate of the storage tank. Since it is collected, it is necessary to feed the liquid to be collected including the floating oil component in small quantities and in a constant amount, so that it is unsuitable for a separation and collection apparatus that requires a large amount of processing capacity. The following describes in detail the actual state of the prior art.

  Regarding the float type floating oil recovery device, for example, an opening provided in the suction port of a submersible pump provided so as not to float and sink in the liquid by the buoyancy of the main float so as to float in the liquid by the buoyancy of the sub-float A gate ring having a part is attached so as to be movable up and down, and floating oil, scum, dust and other floating substances are collected together with liquid at the upper part of the opening part of the gate ring, and flowed into the suction port of the submersible pump from the opening part. A "floating oil recovery device" is provided in which a squeezing means is provided, and the squeezing means is supported by the main float, while the submersible pump is provided with a discharge port for discharging suspended matter together with the liquid flowing in from the suction port (patent) Document 1) has been proposed.

  However, the proposed floating oil recovery device is excellent in recovering oil, scum, etc. with high viscosity as well as light specific gravity, and freely expands the range of use by moving the recovery device floating in the liquid freely However, when installing it, float the float on the unstable liquid level and place the suction port of the submersible pump at the same position as the liquid level to collect the floating oil from all directions. As a result, normal oil other than recovered oil is sucked into the suction port of the submersible pump more than necessary.As a result, the recovery efficiency, recovery probability, and recovery accuracy are reduced, and the submersible pump and By arranging the scraping means and the like, piping, wiring, an electrical control system and a power source are required.

  Further, regarding the mechanical floating oil recovery device, for example, it is disposed in a storage tank, and an oil content guide plate at least partially formed perpendicular to the water surface, and a storage tank An oil recovery container that collects the floating oil that has floated on the surface of the drainage, and an operating body having a handle and a plate, and the operator operates the operating body with the handle so that the plate is After moving toward the oil content guide plate, when moved up in contact with the oil content guide plate, the floating oil is pushed up along the oil content guide plate and collected in the oil recovery container. "Recovery device" (Patent Document 2) has been proposed.

  However, the proposal of such an oil recovery apparatus is said to be able to appropriately recover the floating oil and easily clean the residual particles despite the fact that the configuration is simple and the manufacturing cost is low. It is structurally more complicated to install an operation body such as an oil guide plate above the other than the other oil recovery devices, and requires a lot of maintenance work in liquid level management, cleaning work, and maintenance work. Was.

  In addition, for the bellows suction type floating oil recovery device, for example, a net cover having an open bottom surface is provided, and a suction pipe with a lower half extending downward from the bottom surface opening portion is attached to the center of the top surface. A suction port leading to the inside of the suction pipe is formed in the lower half of the suction pipe, and has a base, a telescopic bellows barrel installed on the base, and an oil inflow hole in the center fixed to the upper portion of the bellows barrel. "Floating oil automatic recovery device" in which a bellows tank is attached to the suction pipe by inserting the suction pipe into the oil inflow hole and fixing its lower end to the base (Patent Document) 3) has been proposed.

  However, the proposed floating oil automatic recovery device has a compact structure and does not cause foreign matter suction and can be used for a long time. However, the bellows tank is retracted to the inlet of the bellows tank by extending and contracting vertically. As normal oil other than oil is sucked in, the liquid level undulates and the recovery efficiency, recovery probability, and recovery accuracy of the floating oil are greatly reduced. In addition, a suction pipe and a suction pump are installed in the equipment. Therefore, installation of piping, wiring, electrical control system, oil / water separator and a power source for operating them were required.

  The screw type floating oil recovery device is a recovery device that separates and recovers, for example, a stock solution mixed with high-viscosity oil into oil and moisture due to a difference in specific gravity. A separation tank provided with a recovery port, a drain tank connected to the separation tank, and a pump for discharging separated water overflowing from the upper part of the drain tank are provided. There has been proposed a “high viscosity oil recovery device” (Patent Document 4) provided with a recovery means for recovering the oil component.

  However, the proposal of such a high-viscosity oil recovery device makes it possible to separate the floating oil in which solid matter is mixed in the high-viscosity oil with a simple structure and recover only the oil content. The use of a pair of screw conveyors with a rotary motor as a recovery means as its recovery means requires expensive production costs such as piping, wiring, electrical control systems and parts costs, and recovery of high viscosity oil In addition to being limited to the apparatus, the suction port is relatively small, and thus it is not suitable as a means for collecting a large amount of floating oil such as a machine tool.

  Further, regarding the belt-type floating oil recovery device, for example, a device attached to a coolant tank of a machine tool and recovering floating oil in a cutting fluid, and a driving roller mounted on the top of the coolant tank, The belt member is made of a mesh material. The belt member is made of a mesh material. The belt member has an endless belt member that is applied to the driving roller and the lower end of the belt member is immersed in the cutting fluid. The belt member is disposed immediately below the driving roller and collects floating oil. In addition, a “floating oil recovery device” (Patent Document 5) including a hook-like bucket attached to the outside of the belt with a gap as appropriate has been proposed.

  However, since the proposed floating oil recovery device recovers only the oil adhering to the belt, the recovered amount is usually small, but the viscosity of the floating oil decreases and does not adhere to the belt when the coolant temperature rises. In addition to solving the problem of almost no recovery, it solves the problem of problems such as swelling of the belt of fibers, rubber, etc. when used in an alkaline solution or high-temperature coolant, or peeling of the adhesive surface. However, there remains a problem in the recovery efficiency such that the recovery area by the belt remains in a very small range with respect to the liquid surface area of the reservoir tank.

  In addition, with regard to the overflow type floating oil recovery device, for example, in a interceptor that separates and collects fat from kitchen wastewater containing a large amount of fats and oils, separation and floating due to the difference in specific gravity of the wastewater-containing fats and oils in the interceptor oil and water separation tank A partition wall having a flow inlet at the bottom of the oil / water separation tank and a partition plate, and an opening at both ends, and one opening penetrates the side wall of the oil / water separation tank in a liquid-tight manner. By opening to the outside, the penetrating position forms a drainage of the treated wastewater that determines the upper surface level of the waste water stored in the oil / water separation tank, and the other opening is submerged in the oil / water separation tank and the bottom of the floating oil layer A generally J-shaped trap, which is an opening that opens upward toward the floating oil layer on the upper layer, and into which the treatment wastewater flows downward toward the bottom of the oil / water separation tank opposite to the direction in which the oil floats due to the difference in specific gravity Consists of That "interceptor-effective interceptor device" (Patent Document 6) have been proposed.

  However, the proposal of the interceptor with high interception efficiency is a proposal of a relatively small oil-water separator for separating oil and water from kitchen wastewater containing a large amount of fats and oils, and the oil-water separation of the interceptor. Regarding the recovery of the floating oil layer remaining in the tank, a separate means such as a schema or a pumping pump is required, and it is attached to the machine tool etc. This is unsuitable for a separation / recovery device that requires a large amount of processing capacity to change.

  In addition, regarding the above-mentioned floating oil recovery device for generating fine bubbles, for example, in an oil / water separation tank in which an oil-mixed mixed waste liquid having an arbitrary flow rate is sequentially fed in a divided amount, the front-stage supernatant liquid is divided into two parts in the flow direction. Is equipped with a partition plate that overflows into the rear stage, and the front stage is equipped with a device that generates fine bubbles at the bottom and a jet nozzle, and oil and water separation that separates oil and waste liquid up and down by oil adsorption and floating effect by the fine bubbles The latter stage is further divided into two in the flow direction, the upstream side is used as a floating oil recovery chamber, and the downstream side communicating with the floating oil recovery chamber at the bottom is a waste liquid drainage chamber. An “oil-water separator” (Patent Document 7) has been proposed in which a waste liquid drain port of a waste liquid drain chamber is provided at a position lower than the recovery port.

  However, the proposal of such an oil-water separator is an oil-water separator that floats and separates oil by the oil adsorption and buoyancy effect of the fine bubbles, and the buoyancy of the fine bubbles in the circulating processing liquid is small and floats in the device. Even when emulsifying, it is a proposal for a relatively small oil-water separator that can reduce the oil concentration of wastewater wastewater and can be separated and recovered without leaving floating oil. Adopting a water supply means requires a delivery pump, and each processing layer, floating oil recovery port and waste liquid drain port recovery means adopt an overflow method, so the upper end of the partition plate and the float suction port In addition, the subtle relationship between the liquid level of each processing chamber and the stability are required, so that the proposal of a relatively small oil-water separator was limited.

  As described above, the conventional floating oil separation and recovery device separates and collects floating oil using mechanical means or electrical means, and makes the suction port for sucking the floating oil the same as the liquid level, Although they are embodied by moving them slightly below the surface, many of them require a complicated electrical control system, oil / water separator, suction device, submersible pump power source, etc. Since a complicated mechanical means is provided, a large amount of floating oil cannot be processed in a short time. Further, when the floating oil component is sucked, the normal oil component is sucked, and problems remain economically, efficiently and accurately. On the other hand, the floating oil is liquefied by utilizing the specific gravity difference between the floating oil and the normal oil contained in the circulating machining fluid as in the present invention, and the natural kinetic energy such as the flow force and drop force of the circulating machining fluid. Layered above the surface, the floating oil component is separated and collected by blocking the falling oil from one direction by a weir plate extending diagonally upward, and the floating oil component size, shape, viscosity, type, and flow rate Regardless, the inventor of the present application has yet to find a floating oil separation and recovery device that can cope with all types of oil water, drainage, cleaning liquid, floating oil, and floating substances.

  However, the floating oil separation and recovery device of the present invention has many advantages of conventional floating oil recovery devices such as float type, mechanical type, bellows suction type, screw type, belt type, overflow type, and fine bubble generation type. In addition to solving many of the problems that have become problems, and adopting a weir system and separation / recovery means using natural kinetic energy, "fat, oily substance or The present invention proposes a floating oil separation and recovery device that employs an unprecedented damming method among the prior arts in the category of “similar floating substance separation or removal device”.

  The inventor of the present application pays attention to the positional relationship between the suction port, the floating oil content sucked in and the liquid level in the conventional floating oil separation and recovery apparatus as described above, and first, a storage tank in which the floating oil separation and recovery apparatus and the circulation pump are provided is provided. Under the idea that the floating oil can be separated and recovered efficiently and effectively by adopting a structure in which the floating oil that is separated and then sucked is laminated above the liquid level. A drainage tank that discharges normal oil to the outside by attaching a floating oil separation hopper to the storage tank that forms the flow path from the upstream to the downstream while damming the upstream of the flow path and in a state where the lower part communicates, and a floating oil content And a dam plate that separates the floating oil flowing in one direction on the floating tank side of the floating oil separation hopper by laminating it obliquely above the liquid level and separating it. Developed a floating oil separation and recovery device using natural kinetic energy as, those leading to proposal of "floating oil separation and recovery device" in the present application.
