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. And the result is that the recovery device must be located on a liquid surface that becomes unstable due to the generation of ripples by the circulation pump. Since it has a structure that flows from all directions of the suction port, the direction of the flow force flowing into the suction port of the submersible pump and the direction of the flow force of the liquid level by the circulation pump partially cancel each other. Unless it was provided, the problem that the floating oil was not efficiently recovered also occurred. 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 recovery flow 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. There is a “floating oil automatic recovery device” (Patent Document 3) in which a bellows tank is provided, and a suction pipe is loosely inserted into an oil inflow hole and a lower end thereof is fixed to a base to attach the bellows tank to the suction pipe. 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, An endless belt member that is applied to the driving roller and has a lower end immersed in the cutting fluid; and a trough that is disposed directly below the driving roller and collects floating oil. The belt member is a belt made of a mesh material. 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, the recovery basin by the belt remains in a very small range with respect to the liquid surface area of the storage tank, and there remains a problem in the recovery efficiency.

  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, They are embodied using means that move up and down with respect to the surface, but many of them require a complicated electrical control system, oil / water separator, suction device, and power source such as a submersible pump to configure the means. In addition, since a complicated mechanical means is provided, a large amount of floating oil cannot be processed in a short time. Furthermore, normal oil which is unnecessary when sucking floating oil is sucked, and problems remain economically, efficiently and accurately. On the other hand, the floating oil is retained 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. The floating oil is separated and collected by a separation / recovery hopper, and all types of oil and water, drainage, cleaning liquid, floating oil, floating matter, regardless of the size, shape, viscosity, type and flow rate of the floating oil. The present inventors have not yet found a floating oil separation and recovery device that can cope with the above.

  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, weirs are unprecedented in the prior art in the classification of "Separation or removal device of fat, oily substance or similar suspended solids" This paper proposes a floating oil separation and recovery device using the method and natural kinetic energy.

  The inventor of the present application pays attention to the installation state of the conventional floating oil separation and recovery device as described above, and the positional relationship between the suction port and the amount of floating oil to be sucked and the liquid level. First, the floating oil separation and recovery device and the circulation pump are provided. The idea is that it can be separated and collected efficiently by separating the storage tank to be collected and then allowing the floating oil component to be sucked next to stay above the liquid level to create a stacked state. The floating oil and normal oil are separated and recovered using the specific gravity difference between the floating oil and normal oil contained in the circulating fluid and the natural kinetic energy such as the fluid force and drop force of the circulating fluid. A floating oil separation and recovery device has been developed, leading to the proposal of a “floating oil separation and recovery device” in the present application.

In I adopted the means for separating and recovering floating oil staying in the 該滞 distillate tank.

  In the floating oil separation and recovery apparatus according to the present invention, the storage tank forms a vertically long tank tank that forms a flow path from upstream to downstream, and is connected to a discharge hose of a machine tool or the like on the upstream side. A discharge duct having a liquid level position adjusting function is connected to the outside of the discharge port on the downstream side, and the partition plate is separated and recovered at a predetermined intermediate position of the flow path of the reservoir tank. The separation and recovery hopper is formed in a shape that avoids the hopper, and the separation and recovery hopper forms a funnel-shaped blocking hopper portion that blocks and prevents floating oil on the upper portion of the discharge cavity main shaft, and the upper portion of the blocking hopper portion or the discharge cavity The bottom end of the main shaft is equipped with a vertical adjustment function and a floating oil discharge pipe that discharges floating oil to the outside is connected.

10) Since it is directly attached to the drainage hose of the processing / machine tool and separated and collected, it is easy to install and does not require installation space.
(11) Because it is lightweight, small and has a simple structure, it can be externally attached to an existing storage tank and installed inside an existing or new processing / machine tool.

According to the floating oil separation and recovery apparatus of the present invention, a damming system that is completely different from the conventional floating oil content recovery means of the float type, mechanical type, bellows suction type, screw type, belt type, and overflow type is adopted. Because
(1) Since the floating oil separation and recovery device is directly attached to the drain hose drained into the storage tank, the floating oil component does not accumulate on the liquid level of the conventional storage tank.
(2) Light weight, small size, and simple structure, so the product price is less than half of the conventional product (in some cases, less than 1/10) and at the same time, including peripheral accessories, the user's price retroactive requirements Can be fully met.
(3) Floating oil is separated and recovered using natural kinetic energy such as floating oil flow force, head, and buoyancy, so there is no running cost such as operation and maintenance costs such as electricity charges and mechanical maintenance management. .

(5) Since the intake port of the separation and recovery hopper is large, the floating oil can be efficiently and effectively separated and recovered.
(6) Since the flow path from the inlet in the storage tank to the separation and recovery hopper is secured in the water surface, the floating oil component is collected by floating upward, and the normal oil component is circulated toward the discharge port. Since it is discharged directly by the flow force, separation / recovery accuracy is high, and separation / recovery can be performed efficiently and effectively.

(10) Since it is a structure that is directly attached to a drainage hose of a processing / machine tool and separated / collected, it is easy to attach and does not require an installation space.
(11) Since it is lightweight, small and has a simple structure, it can be externally attached to an existing storage tank, and can also be installed inside an existing or new processing / machine tool.
(12) Since it can be molded from an oil-resistant synthetic resin material, it can be mass-produced at low cost.
(13) Since mechanical, electrical, and pneumatic operation means are not required, auxiliary equipment such as submersible pumps, oil / water separators, air compressors, and solenoid valves are not required, leading to lower installation costs and maintenance costs. There is an excellent effect that it is greatly reduced.

  Further, according to the floating oil separation and recovery apparatus of the present invention, since it has a simple structure and does not require an electrical operation source, it is necessary to use a large-scale factory, small-scale factory, large-scale fuel storage facility, marine accident oil recovery ship, lake floating matter.
