Description

Technical Field

[0001] This utility model relates to the field of cutting fluid preparation technology, and in particular to a gradient mixing and stirring device for preparing microemulsion cutting fluid. Background Technology

[0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate cutting tools and workpieces. Its production requires the mixing of various raw materials in specific proportions, thus necessitating the use of gradient mixing and stirring devices.

[0003] Patent CN219722686U discloses a cutting fluid mixing device, including a base, a mixing device, and a filling device. It includes a venting device connected to a stirring device. The stirring device comprises a stirring motor, a stirring shaft, and a stirring rod. The stirring shaft and stirring rod are hollow structures interconnected and have vent holes. The venting device includes a rotary joint, an air inlet pipe, and a fan. One end of the stirring shaft is connected to the stirring motor, and the other end is connected to the fan via the rotary joint and the air inlet pipe.

[0004] In the above case, different raw materials are added to the mixing tank in sequence, and then the stirring rod is driven by a motor to stir the raw materials. Air is blown into the inside of the stirring rod through a fan and air inlet pipe and sprayed out from the air outlet to accelerate the mixing speed. However, the continuous stirring of the raw materials at a single speed by the stirring rod will cause the raw materials to form a stable rotating flow inside the mixing tank. As a result, the raw materials at the top and bottom of the mixing tank rarely come into contact, resulting in insufficient mixing and a low yield of cutting fluid produced by the device.

[0005] Therefore, this invention provides a gradient mixing and stirring device for preparing microemulsion cutting fluid to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to provide a gradient mixing and stirring device for preparing microemulsion cutting fluid, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gradient mixing and stirring device for preparing microemulsion cutting fluid, comprising a mixing tank for preparing the cutting fluid, a rotating shaft rotatably connected to the top of the mixing tank, a rotating seat rotatably connected to the middle of the outer side of the rotating shaft, stirring blades fixedly connected to the top and bottom of the outer side of the rotating shaft, central rotating blades fixedly connected to both sides of the rotating seat, a limiting ring rotatably connected to the inner side of the top of the rotating seat, a connecting rod fixedly connected to one side of the limiting ring, a central rotating gear rotatably connected to the outer side of the bottom end of the connecting rod, a driving gear fixedly connected to the outer side of the rotating shaft located inside the rotating seat, a gear ring fixedly connected inside the rotating seat, the two sides of the central rotating gear meshing with the driving gear and the gear ring respectively, the diameter of the gear ring being larger than that of the driving gear, the top of the limiting ring penetrating through the rotating seat and fixedly connected to the two sides of the side rod, the other end of the side rod being fixedly connected to the inner wall of the mixing tank, a bottom plate fixedly connected to the bottom end of the inner cavity of the mixing tank, and the bottom end of the rotating shaft penetrating through the bottom plate and fixedly connected to the bottom ring.

[0008] In a preferred embodiment, a motor is fixedly connected to the top of the mixing tank, the output end of the motor is fixedly connected to a rotating shaft, and a retaining ring is fixedly connected to the contact surface between the rotating shaft and the top of the mixing tank.

[0009] In a preferred embodiment, a feed pipe is fixedly connected to the top of one side of the mixing tank, an auxiliary material pipe is fixedly connected to the top of the mixing tank, a discharge pipe is fixedly connected to the bottom of the mixing tank, and a valve is fixedly connected to the outside of the discharge pipe.

[0010] In a preferred embodiment, the bottom of the mixing tank is fixedly connected to the four sides of the support legs, and the side of the mixing tank is fixedly connected to the observation window.

[0011] In a preferred embodiment, an air pump is fixedly connected to one side of the mixing tank, the air pump is fixedly connected to an air pipe, and a sleeve block for limiting the air pipe is fixedly connected to the bottom of the base plate.

[0012] In a preferred embodiment, the end of the air pipe away from the air pump extends into the mixing tank and is fixedly connected to a nozzle. The inside of the rotating shaft is provided with a ventilation chamber, and the outside of the rotating shaft is provided with several air outlets located inside the two stirring blades. The nozzle is rotatably connected to the bottom end of the ventilation chamber.

[0013] In a preferred embodiment, a lower retaining ring is fixedly connected to the outer side of the rotating shaft at the bottom of the rotating base, and the limiting ring includes an upper retaining ring located above the rotating base. The rotating base is engaged with the inner sides of the upper and lower retaining rings, and sealing gaskets are fixedly connected to the contact surfaces of the limiting ring, the rotating base, and the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, by setting up a rotating base, a central rotating blade, a gear ring, a drive gear, and a central rotating gear, allows the rotating shaft to drive the rotating blades to rotate. The drive gear and the central rotating gear, in turn, drive the gear ring, rotating base, and central rotating blades to rotate. The difference in diameter between the gear ring and the drive gear ensures that the upper and lower stirring blades rotate at a higher speed than the central rotating blade, creating a speed difference. This causes the raw materials to flow from the top and bottom to the center while rotating within the mixing tank, increasing the contact area and time between different areas of the raw materials, thus accelerating the mixing speed and enhancing the mixing effect.

[0016] This utility model, by setting a limiting ring, a lower retaining ring, and a base plate, allows the limiting ring to provide a rotating platform for the central gear through the connecting rod. The upper and lower retaining rings work together to limit the rotation seat, preventing it from derailing and improving the stability of the rotation seat. The base plate limits the rotation shaft and air pipe, further ensuring the stability of the rotating structure while preventing the air pipe from being wrapped by the raw material and causing it to displace.

Detailed Implementation

[0022] The present invention will be further described below with reference to the embodiments.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Please see Figures 1-4This utility model provides a gradient mixing and stirring device for preparing microemulsion cutting fluid, including a mixing tank 1 for preparing the cutting fluid. A rotating shaft 2 is rotatably connected to the top of the mixing tank 1, and a rotating seat 3 is rotatably connected to the middle of the outer side of the rotating shaft 2. Stirring blades 11 are fixedly connected to the top and bottom of the outer side of the rotating shaft 2. A bottom plate 20 is fixedly connected to the bottom of the inner cavity of the mixing tank 1. The bottom of the rotating shaft 2 passes through the bottom plate 20 and is fixedly connected to a bottom ring. A motor 16 is fixedly connected to the top of the mixing tank 1. The output end of the motor 16 is fixedly connected to the rotating shaft 2. A retaining ring is fixedly connected to the contact surface between the rotating shaft 2 and the top of the mixing tank 1. A feed pipe 18 is fixedly connected to the top of one side of the mixing tank 1. An auxiliary material pipe is fixedly connected to the top of the mixing tank 1. A discharge pipe 17 is fixedly connected to the bottom of the mixing tank 1. A valve is fixedly connected to the outer side of the discharge pipe 17. Support legs 19 are fixedly connected around the bottom of the mixing tank 1. An observation window is fixedly connected to one side of the mixing tank 1.

[0025] The required cutting fluid main material and auxiliary material are added into the mixing tank 1 through the feed pipe 18 and the auxiliary material pipe, respectively. The motor 16 is started to drive the rotating shaft 2 to rotate, which drives the stirring blades 11 on the outside of the rotating shaft 2 to stir and mix the raw materials. The rotating shaft 2 is limited by the bottom plate 20.

[0026] Please see Figures 1-4 Rotary base 3 has central rotating blades 12 fixedly connected to both sides. A limiting ring 4 is rotatably connected to the inner side of the top of rotary base 3. A connecting rod 6 is fixedly connected to one side of the limiting ring 4. A central rotating gear 7 is rotatably connected to the outer side of the bottom end of the connecting rod 6. A drive gear 5 is fixedly connected to the outer side of the rotating shaft 2 inside rotary base 3. A gear ring 8 is fixedly connected inside rotary base 3. The two sides of the central rotating gear 7 mesh with the drive gear 5 and the gear ring 8 respectively. The diameter of the gear ring 8 is larger than that of the drive gear 5. The top of the limiting ring 4 extends through rotary base 3 and is fixedly connected to side rods 10 on both sides. The other end of the side rods 10 is fixedly connected to the inner wall of mixing tank 1. An air pump 1 is fixedly connected to one side of mixing tank 1. 3. The air pump 13 is fixedly connected to the air pipe 14. The bottom of the base plate 20 is fixedly connected to the sleeve block for limiting the air pipe 14. The end of the air pipe 14 away from the air pump 13 passes through the mixing tank 1 and is fixedly connected to the nozzle. The inside of the rotating shaft 2 is provided with a ventilation chamber. Several air outlets 15 are provided on the outside of the rotating shaft 2 on the inside of the two stirring blades 11. The nozzle is rotatably connected to the bottom of the ventilation chamber. The bottom of the rotating seat 3 is fixedly connected to the outside of the rotating shaft 2. The limiting ring 4 includes an upper retaining ring located above the rotating seat 3. The rotating seat 3 is snapped into the inside of the upper retaining ring and the lower retaining ring 9. The contact surfaces of the limiting ring 4, the rotating seat 3 and the rotating shaft 2 are all fixedly connected with sealing gaskets.

[0027] As the rotating shaft 2 rotates, it drives the drive gear 5 to rotate, which in turn drives the gear ring 8 to rotate through the intermediate rotating gear 7. This causes the rotating base 3 to drive the intermediate rotating blade 12 to rotate at a slower speed. The air pump 13 is started, and gas is delivered into the mixing tank 1 through the air pipe 14. The gas enters the ventilation chamber through the nozzle and is evenly sprayed into the raw materials through the air outlet 15 to accelerate the mixing speed. After mixing is completed, the valve of the discharge pipe 17 is opened to discharge the cutting fluid from the mixing tank 1.

[0028] The diameter of the gear ring 8 is larger than that of the drive gear 5, which makes the rotation speed of the rotating seat 3 and the central rotary blade 12 driven by the gear ring 8 slower than that of the stirring blade 11. When the stirring blades 11 at the upper and lower ends stir the raw materials in the mixing tank 1 at a faster speed, strong convection and shear force are formed, causing them to flow towards the area with a slower flow rate in the middle, presenting a complex flow pattern that converges from the top and bottom to the middle. This flow pattern not only increases the mixing speed but also increases the contact area and contact time between raw materials in different areas, enabling the raw materials to reach a uniform mixing state in a short time.

[0029] The limiting ring 4 provides a stable rotating platform for the central rotating gear 7, ensuring that the central rotating gear 7 can maintain a smooth and continuous rotation under the combined action of the drive gear 5 and the gear ring 8, thereby driving the rotating seat 3 and the central rotating blade 12 to perform stable mixed operation. The cooperation of the upper and lower retaining rings 9 effectively limits the rotating seat 3, ensuring the stability of the rotating seat 3 during rotation and avoiding the risk of derailment due to uneven force or improper operation. The base plate 20 not only limits the rotating shaft 2, ensuring the stability of the rotating shaft 2 during rotation, but also effectively fixes the air pipe 14 through a specific design, ensuring the continuous stability and safety of the device during long-term operation.

[0030] The working principle and usage process of this utility model are as follows: The required cutting fluid main material and auxiliary material are added into the mixing tank 1 through the feed pipe 18 and the auxiliary material pipe, respectively. The motor 16 is started to drive the rotating shaft 2 to rotate, which drives the stirring blade 11 on the outside of the rotating shaft 2 to stir and mix the raw materials. The rotating shaft 2 is limited by the bottom plate 20. When the rotating shaft 2 rotates, it drives the drive gear 5 to rotate, which drives the gear ring 8 to rotate through the intermediate rotating gear 7, so that the rotating seat 3 drives the intermediate rotating blade 12 to rotate at a relatively slow speed. The air pump 13 is started to deliver gas into the mixing tank 1 through the air pipe 14. The gas enters the ventilation chamber through the nozzle and is evenly sprayed into the raw materials through the air outlet 15 to speed up the mixing speed. After the mixing is completed, the valve of the discharge pipe 17 is opened to discharge the cutting fluid from the mixing tank 1.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
