Abstract
Description
Technical Field
[0001] This utility model relates to the field of stirring and mixing devices, and more specifically to a stirring and mixing device for metal processing oils. Background Technology
[0002] Metalworking fluids are functional liquids used in metal cutting, forming, grinding, and other machining processes. They primarily improve machining quality, extend tool life, and improve the operating environment through lubrication, cooling, cleaning, and rust prevention. For example, they reduce friction between the tool and the workpiece, lower cutting forces and wear, and are particularly suitable for high-hardness or high-precision machining scenarios; they absorb heat generated during machining, preventing workpiece deformation due to high temperatures and maintaining tool performance (e.g., carbide tools require strict temperature control). Common metalworking fluids include cutting oils, stamping oils, quenching oils, high-temperature oils, and rust-preventive oils. In the production of metalworking fluids, the fluid is usually composed of a mixture of various raw materials. Therefore, a mixing device is needed to mix the various raw materials. Through the mechanical movement of components such as stirring rods and scrapers, the fluid is forced to flow, breaking up "molecular aggregation" or "phase separation," so that additives are uniformly dispersed in the base oil at the nano or micron level, forming a stable system.
[0003] For example, the prior art disclosure number CN222753019U discloses a mixing device for metalworking fluids. This utility model involves pouring the raw material to be mixed into a tank, covering the tank, starting the stirring motor, causing the rotating shaft to rotate, which in turn causes the first stirring blade to rotate, stirring the fluid horizontally. Through the meshing of the first and second bevel gears, the rotating rod rotates, driving the second stirring blade to rotate, stirring the fluid vertically. Compared with the existing devices, which have a relatively single stirring direction, this device can stir the fluid in multiple directions, making the stirring more thorough and the mixing more uniform, thus improving the quality of the fluid mixture and facilitating the mixing of the fluid.
[0004] However, the existing technology described above still has the following problems in use: because the oil contains impurities, when these impurities are stirred and mixed with the oil, they not only affect the mixing effect but also damage the stirring structure, thereby shortening the service life of the device. Furthermore, due to the viscosity of the oil, the impurities adhere to the inner wall of the device and are difficult to clean. Based on this, the present invention provides a stirring and mixing device for metalworking oil with a filtering function. Utility Model Content
[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a stirring and mixing device for metalworking fluids. The metalworking fluid is filtered by a filter plate inside the inlet hopper to prevent impurities from affecting subsequent stirring and mixing. The motor drives the rotating shaft and stirring rod to stir the fluid, which can improve the mixing efficiency. The cleaning plate scrapes off the oil adhering to the tank wall to avoid affecting the stirring. At the same time, the impurities on the surface of the rotating filter plate are dispersed, which can improve the filtration efficiency, thereby solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a stirring and mixing device for metal processing oil, comprising a mixing tank, a sealing cover fixedly provided on the top of the mixing tank, an inlet hopper fixedly provided on the top of the sealing cover, and the bottom of the inlet hopper communicating with the interior of the mixing tank, a filter plate provided inside the inlet hopper, a rotating shaft fixedly passing through the top of the filter plate, the bottom end of the rotating shaft passing through the sealing cover and extending into the interior of the mixing tank, two cleaning plates and multiple stirring rods fixedly provided on the outer wall of the rotating shaft, and the outer walls of the two cleaning plates contacting the inner wall of the mixing tank.
[0007] In a preferred embodiment, a cover plate is detachably installed on the top of the liquid inlet hopper, and a liquid filling pipe is fixedly inserted through one side of the top of the cover plate. A first threaded cap is threadedly connected to the top of the liquid filling pipe to seal the liquid filling pipe and prevent oil leakage.
[0008] In a preferred embodiment, a bracket is fixedly provided on the top of the mixing tank, and a motor is fixedly provided on the top of the bracket. The bottom end of the motor output shaft is connected to the top end of the rotating shaft through a coupling. The motor drives the rotating shaft to rotate, which can improve the mixing efficiency and prevent the filter plate from being blocked by impurities, thereby improving the filtration efficiency.
[0009] In a preferred embodiment, a rubber sealing ring is provided between the sealing cap and the mixing tank to fill the gap between them. A pressure relief valve is fixedly provided on one side of the top of the sealing cap. The pressure relief valve is connected to the inside of the mixing tank. The pressure relief valve is provided to facilitate the discharge of gas generated by stirring and mixing, thereby maintaining the gas pressure balance inside the mixing tank.
[0010] In a preferred embodiment, a drain pipe is fixedly inserted through the bottom of the mixing tank. A sealing plug is provided inside the drain pipe. A connecting rod is movably connected to the bottom of the sealing plug. The connecting rod is threadedly connected to the drain pipe through a second threaded cap, which facilitates the removal of the sealing plug by the operator to drain the stirred and mixed oil.
[0011] In a preferred embodiment, a support frame is fitted on the outer wall of the mixing tank. The support frame is detachably installed with the mixing tank by multiple bolts. The support frame provides stable support for the mixing tank, and its height is designed to facilitate the placement of a collection container below the drain pipe to collect the discharged oil.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] This invention filters the metalworking oil through a filter plate inside the inlet hopper to prevent impurities from affecting the subsequent stirring and mixing effect. A motor drives the rotating shaft to rotate, and multiple stirring rods on the shaft agitate the oil, which can improve the mixing efficiency of the oil. At the same time, two cleaning plates on the shaft scrape off the oil adhering to the inner wall of the mixing tank, preventing oil from adhering and affecting the stirring effect.
[0014] In addition, the rotating shaft drives the filter plate to rotate in the inlet hopper, and the filter plate generates centrifugal force, which can disperse impurities on the surface of the filter plate, thereby improving the filtration efficiency of the oil and thus improving the production efficiency of the oil.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Refer to the instruction manual appendix Figures 1-5This utility model provides a stirring and mixing device for metal processing oil, including a mixing tank 1. A sealing cover 2 is fixedly provided on the top of the mixing tank 1. An inlet hopper 3 is fixedly provided on the top of the sealing cover 2, and the bottom of the inlet hopper 3 is connected to the inside of the mixing tank 1. A filter plate 4 is provided inside the inlet hopper 3. A rotating shaft 5 is fixedly passed through the top of the filter plate 4. The bottom end of the rotating shaft 5 passes through the sealing cover 2 and extends into the inside of the mixing tank 1. Two cleaning plates 6 and multiple stirring rods 7 are fixedly provided on the outer wall of the rotating shaft 5. The outer walls of the two cleaning plates 6 are in contact with the inner wall of the mixing tank 1.
[0023] The top of the liquid inlet hopper 3 is detachably fitted with a cover plate 8. A liquid filling pipe 9 is fixedly inserted through one side of the top of the cover plate 8. A first threaded cap 10 is threadedly connected to the top of the liquid filling pipe 9. After the oil is added, the staff will tighten the first threaded cap 10 to prevent impurities in the outside air from causing contamination.
[0024] The top of the mixing tank 1 is fixedly equipped with a bracket 11, and the top of the bracket 11 is fixedly equipped with a motor 12. The bottom end of the output shaft of the motor 12 is connected to the top end of the rotating shaft 5 through a coupling.
[0025] In actual use, the operator pours the metal processing oil and additives into the inlet hopper 3 through the inlet pipe 9. When the oil passes through the filter plate 4, the filter plate 4 traps impurities in the oil to prevent them from affecting the subsequent stirring and mixing effect. The filtered oil then flows into the mixing tank 1 from the inlet hopper 3. At this time, the motor 12 drives the rotating shaft 5 to rotate, and the multiple stirring rods 7 on the rotating shaft 5 stir the oil to improve the mixing efficiency. At the same time, the two cleaning plates 6 on the rotating shaft 5 rotate synchronously with the rotating shaft 5 to scrape off the oil adhering to the inner wall of the mixing tank 1 to prevent the oil from affecting the stirring effect.
[0026] Refer to the instruction manual appendix Figure 4 A rubber sealing ring 13 is provided between the sealing cover 2 and the mixing tank 1 to fill the gap between them. A pressure relief valve 14 is fixedly provided on one side of the top of the sealing cover 2. The pressure relief valve 14 is connected to the inside of the mixing tank 1. The pressure relief valve 14 is an automatic valve. When the internal pressure of the mixing tank 1 exceeds the set value, it automatically opens to release the excess pressure, preventing the mixing tank 1 from explosion, leakage and other safety accidents due to overpressure. At the same time, it automatically closes after the pressure returns to normal, maintaining the stable operation of the system.
[0027] like Figures 1-3 As shown, a drain pipe 15 is fixedly inserted through the bottom of the mixing tank 1. A sealing plug 16 is provided inside the drain pipe 15. A connecting rod 17 is movably connected to the bottom of the sealing plug 16. The connecting rod 17 is threadedly connected to the drain pipe 15 through a second threaded cap 18. A support frame 19 is fitted on the outer wall of the mixing tank 1. The support frame 19 and the mixing tank 1 are detachably installed together by multiple bolts.
[0028] After the oil is mixed, the operator unscrews the second threaded cap 18. The second threaded cap 18 moves the sealing plug 16 down through the connecting rod 17 and out of the drain pipe 15, allowing the oil to be discharged from the drain pipe 15. The support frame 19 supports the mixing tank 1, making it easy for the operator to place the collection box under the drain pipe 15 for collection. In addition, in actual use, the second threaded cap 18 can be reinforced by connecting the drain pipe 15 with bolts.
[0029] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
