Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a multifunctional liquid storage device. Background Art

[0002] Cutting fluid is an essential component of the precision machining industry, providing cooling, lubrication, rust prevention, and cleaning. However, during the machining process, the cutting fluid can become contaminated with large amounts of solid particulate impurities (such as silicon powder and metal debris). Left untreated, these impurities can directly impact the performance of the cutting fluid and, in turn, the quality of the product. To save costs and improve machining efficiency, cutting fluids are often filtered and recycled for reuse.

[0003] However, due to the large amount of cutting fluid to be processed, the filtration equipment cannot meet the filtration needs in one go. Therefore, a transfer tank is usually installed between the processing equipment and the filtration equipment. The transfer tank is used to store and regulate the supply of cutting fluid, ensuring a stable supply of cutting fluid throughout the entire processing process.

[0004] Existing transfer tanks typically adopt an inverted cone design, with the inlet located at the top and the outlet at the bottom. While this design facilitates the natural settling of solid particles, in practice, the accumulation of solid particles and other impurities can easily lead to clogging of the outlet, thus affecting the normal flow of cutting fluid.

[0005] In addition, in addition to solid particles, the cutting fluid may also contain oily substances. The presence of these oily substances will also have an adverse effect on the filtering effect and even shorten the service life of the filtering device. Utility Model Content

[0006] The purpose of this utility model is to provide a multifunctional liquid storage device, which not only has the function of temporary storage, but more importantly, it can achieve three-phase separation of solid, water and oil while storing, effectively remove solid particles and oily substances in the cutting fluid, thereby ensuring that the cutting fluid can flow smoothly during filtration, extending the service life of the filtering device, and at least solving one of the above problems.

[0007] According to one aspect of the utility model, a multifunctional liquid storage device is provided, including a liquid storage tank and an inclined plate. The liquid storage tank includes a tank body, a liquid inlet arranged at the upper end of the tank body, and a liquid outlet arranged at the lower end of the tank body. The inclined plate is arranged inside the tank body and extends downward from the middle position of the tank body at an inclined angle to the inner wall of the tank body. The inclined plate divides the inner cavity of the tank body into two areas: a separation area and a liquid storage area.

[0008] In some embodiments, there is a gap between the upper end of the inclined plate and the top and interior of the tank body to form an overflow port, and the overflow port connects the separation area and the liquid storage area.

[0009] In some embodiments, the upper end surface of the inclined plate is provided with multiple stepped surfaces.

[0010] In some embodiments, the multifunctional liquid storage device further includes an oil removal mechanism, which is installed in the liquid storage tank and has a bottom extending into the separation zone, for removing oily substances from the cutting fluid.

[0011] In some embodiments, the multifunctional liquid storage device also includes an oil baffle, which is installed in the tank body and cooperates with the inclined plate to block and gather oily substances on the upper surface of the cutting fluid after the liquid level in the separation area rises. The upper end surface of the oil baffle is higher than the upper port of the inclined plate, and the lower end surface is lower than the upper port of the inclined plate.

[0012] In some embodiments, the oil baffle is formed with an angled structure, thereby facilitating the rapid collection of oily substances on the upper surface of the cutting fluid, thereby facilitating the oil removal work of the oil removal mechanism.

[0013] In some embodiments, the liquid storage tank also includes a cover plate, which is installed on the upper port of the tank body, the upper end of the oil baffle is in contact with the bottom surface of the cover plate, the oil removal mechanism is installed on the cover plate and the bottom end extends from the outside of the cover plate through the cover plate to the separation area of ​​the tank body.

[0014] In some embodiments, the multifunctional liquid storage device further includes a control valve and an on-off valve, wherein the control valve is installed at the liquid inlet and cooperates with the liquid inlet, and the on-off valve is arranged at the liquid outlet and cooperates with the liquid outlet.

[0015] In some embodiments, the multifunctional liquid storage device further includes a liquid level gauge, which is mounted on the tank body and has one end extending into the liquid storage area.

[0016] In some embodiments, the multifunctional liquid storage device further includes a switch valve, a drain outlet is provided on the tank body, the drain outlet is located at the bottom of the separation zone, and the switch valve is provided at the drain outlet and cooperates with the drain outlet.

[0017] Beneficial effects of the utility model:

[0018] The utility model provides a liquid storage device with a novel structure. The liquid storage device is provided with an inclined plate, which can separate the inner cavity of the tank body into two areas: a separation area and a liquid storage area. The cutting fluid enters the tank body through the liquid inlet and first flows onto the upper surface of the inclined plate. Since the inclined plate increases the flow path length of the liquid, under the action of the inclined plate, the contact time between the solid particles in the cutting fluid and the surface of the inclined plate can be prolonged, thereby causing the solid particles in the cutting fluid to fall on the surface of the inclined plate and slide to the bottom along the inclined surface and gather at the drain outlet. This method accelerates the sedimentation rate of the particulate matter in the cutting fluid and achieves a good solid-liquid separation effect. After the separation, the cutting fluid can flow into the liquid storage area from the overflow port at the top for storage after reaching a certain height. When it needs to be used, the liquid outlet can be opened.

[0019] The liquid storage device is also provided with an oil removal mechanism and an oil baffle, which can quickly and effectively remove oily substances in the cutting fluid, achieving a good oil-liquid separation effect;

[0020] In summary, the liquid storage device of the present invention not only has the function of temporary storage, but more importantly, it can achieve three-phase separation of solid, water and oil while storing, effectively removing solid particles and oily substances in the cutting fluid, thereby ensuring that the cutting fluid can flow smoothly during filtration and extending the service life of the filtering device.

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Figures 1-2 A multifunctional liquid storage device according to an embodiment of the present invention is schematically shown.

[0026] like Figures 1-2As shown, the multifunctional liquid storage device includes a liquid storage tank 1 and an inclined plate 2. The liquid storage tank 1 includes a tank body 11, a liquid inlet 13 provided at the upper end of the tank body 11, and a liquid outlet 14 provided at the lower end of the tank body 11. The inclined plate 2 is provided inside the tank body 11 and extends downward from the middle position of the tank body 11 at an inclined angle to the inner wall of the tank body 11. The inclined plate 2 divides the inner cavity of the tank body 11 into two areas: a separation area 11A and a liquid storage area 11B. The upper end surface of the inclined plate 2 is provided with multiple steps 21, each step surface 21 having a certain inclination angle, forming a structure similar to a staircase. A sewage outlet 15 is provided on the tank body 11, and the sewage outlet 15 is located at the bottom of the separation area 11A. A gap exists between the upper end of the inclined plate 2 and the top and interior of the tank body 11 to form an overflow port 16. The overflow port 16 connects the separation area 11A and the liquid storage area 11B.

[0027] The multifunctional liquid storage device also includes an oil removal mechanism 3, which is installed in the liquid storage tank 1 and extends into the separation area 11A at the bottom to remove oily substances from the cutting fluid. The oil removal mechanism 3 of this embodiment is a commercial product, specifically a belt oil-water separator.

[0028] The multifunctional liquid storage device also includes an oil baffle 9, which is installed in the tank body 11 and cooperates with the inclined plate 2. It is used to block and gather the oily substances on the upper layer of the cutting fluid after the liquid level in the separation area 11A rises. The upper end surface of the oil baffle 9 is higher than the upper port of the inclined plate 2, and the lower end surface is lower than the upper port of the inclined plate 2.

[0029] The oil baffle plate 9 is formed with an angled structure 91 , which facilitates the rapid collection of oily substances on the upper surface of the cutting fluid, thereby facilitating the oil removal work of the oil removal mechanism 3 .

[0030] The liquid storage tank 1 also includes a cover plate 12, which is installed on the upper end of the tank body 11. The upper end of the oil baffle plate 9 is in contact with the bottom surface of the cover plate 12. The oil removal mechanism 3 is installed on the cover plate 12 and the bottom end extends from the outside of the cover plate 12 through the cover plate 12 to the separation area 11A of the tank body 11.

[0031] The multifunctional liquid storage device further includes a control valve 4, a switch valve 5 and an on-off valve 6. The control valve 4 is mounted on and matched with the liquid inlet 13. The switch valve 5 is arranged at the sewage outlet 15. The on-off valve 6 is arranged at the liquid outlet 14.

[0032] The multifunctional liquid storage device also includes a liquid level gauge 7, which is mounted on the tank body 11 and extends into the liquid storage area 11B at one end. The liquid level gauge 7 is used to monitor the level of the cutting fluid in the liquid storage area 11B in real time. When the liquid level gauge 7 detects that the cutting fluid level in the liquid storage area 11B is high, the control valve 4 is closed, and no more liquid is introduced.

[0033] The on-off valve 6 and the control valve 4 can be opened at the same time, and the liquid inlet 13 and the liquid outlet 14 of the multifunctional liquid storage tank 1 are connected to the processing equipment and the filtering equipment respectively, and can be used as a transfer equipment online in real time.

[0034] When solid particles accumulate to a certain level in separation zone 11A, control valve 4 closes, stopping the flow of liquid into liquid inlet 13. Opening valve 5 allows the dirty liquid, which contains a large amount of solid particles, to be discharged from drain outlet 15 for recycling. Once the dirty liquid, which contains a large amount of solid particles, has been completely drained, closing valve 5 allows the multifunctional liquid storage device to continue functioning as a multifunctional intermediate storage device.

[0035] The multifunctional liquid storage device further comprises a support frame 8, which is mounted below the tank body 11 and is position-limited with the tank body 11. Thus, the support frame 8 can provide good support and position-limiting effects, ensuring the overall stability of the device.

[0036] The present utility model provides a liquid storage device with a new structure. The liquid storage device is provided with an inclined plate 2, which can separate the inner cavity of the tank body 11 into two areas: a separation area 11A and a liquid storage area 11B. The cutting fluid enters the tank body 11 through the liquid inlet 13 and first flows onto the upper surface of the inclined plate 2. Since the inclined plate 2 increases the flow path length of the liquid, under the action of the inclined plate 2, the contact time of the solid particles in the cutting fluid and the surface of the inclined plate 2 can be prolonged, so that the solid particles in the cutting fluid fall on the surface of the inclined plate 2 and slide to the bottom along the inclined surface and gather at the drain port 15. This method accelerates the sedimentation rate of the particulate matter in the cutting fluid and achieves a good solid-liquid separation effect. After the separation, the cutting fluid can flow into the liquid storage area 11B from the overflow port 16 at the top for storage after reaching a certain height. When it needs to be used, the liquid outlet 14 can be opened.

[0037] The liquid storage device is also provided with an oil removal mechanism 3 and an oil baffle 9, which can quickly and effectively remove oily substances in the cutting fluid, achieving a good oil-liquid separation effect;

[0038] In summary, the liquid storage device of the present invention not only has the function of temporary storage, but more importantly, it can achieve three-phase separation of solid, water and oil while storing, effectively removing solid particles and oily substances in the cutting fluid, thereby ensuring that the cutting fluid can flow smoothly during filtration and extending the service life of the filtering device.

[0039] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
