Description

Technical Field

[0001] This utility model relates to the technical field of graphite emulsion stirring devices, and more specifically, to a fully automatic graphite emulsion stirring device for a wire drawing machine. Background Technology

[0002] Existing graphite emulsion agitators mainly consist of a stirring motor, stirring shaft, folded blades, and a cylindrical assembly, as shown in the diagram. The folded blades function as axial, radial, and circumferential flow dividers. The stirring motor operates at a slow speed, providing weak effective shearing force, resulting in long mixing times and low efficiency. During cylinder cleaning, workers simply scrub through the colloidal graphite emulsion inlet, leading to incomplete cleaning of the inner wall. The workflow is as follows: colloidal graphite emulsion is manually poured into the cylindrical assembly through the inlet, followed by a certain amount of purified water. The stirring motor is then started, and the graphite emulsion is mixed. A manual valve is connected to the graphite emulsion outlet, and the mixed emulsion is discharged through the outlet. However, when colloidal graphite emulsion is poured into a conventional agitator, the agitator speed is too low, and the blade design is limited, failing to provide strong shearing force. This results in excessively large colloidal graphite emulsion particles, poor and unstable lubrication performance for wires of different diameters during drawing, and prolonged operation leads to high graphite emulsion temperatures, which can cause graphite emulsion denaturation. Utility Model Content

[0003] The purpose of this invention is to provide a fully automatic graphite emulsion stirring device for a wire drawing machine, which addresses the shortcomings of the prior art and solves the problems mentioned in the background.

[0004] The technical solution of this utility model is implemented as follows: The utility model provides a fully automatic graphite emulsion stirring device for a wire drawing machine, including a cylindrical structure.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] Example This utility model provides a fully automatic graphite emulsion stirring device for a wire drawing machine, such as... Figures 1-4As shown, the device includes a cylindrical structure 4. The cylindrical structure 4 is cylindrical in shape, and a cover plate 3 is installed on the top of the cylindrical structure 4 by hinges or bolts. The cover plate 3 closes the cylindrical structure 4 to form a sealed area. A stirring shaft 17 is installed on the cover plate 3 via bearings and is placed inside the cylindrical structure 4. There is a certain gap between the stirring shaft 17 and the bottom of the cylindrical structure 4. An impeller structure 15 is provided on the outer wall of the stirring shaft 17, and a toothed dispersion disk 14 is installed at the end of the stirring shaft 17. The stirring shaft 17 drives the outer impeller structure 15 and the toothed dispersion disk 14 at the end to rotate, thereby shearing, mixing and dispersing the graphite emulsion inside the cylinder. A circulating cooling structure (such as a jacket) is installed inside the cylindrical structure 4. The circulating cooling structure continuously introduces constant temperature water, which exchanges heat with the material through the cylinder wall to ensure that the graphite emulsion is always at a stable temperature during stirring, thus ensuring the activity of the graphite emulsion and maximizing its performance. A drive mechanism is installed on the top of the cover plate 3. The first drive mechanism 1 is connected to the stirring shaft 17 via a coupling. A nozzle structure 9 is installed on the top of the cover plate 3. The output end of the nozzle structure 9 is placed inside the cylinder structure 4. A second drive mechanism is provided on the cover plate 3 to drive the nozzle structure 9. The second drive mechanism drives the nozzle structure 9. The nozzle sprays liquid into the cylinder during rotation or oscillation, or cleans the components inside the cylinder structure 4 after the graphite emulsion is stirred. This structure achieves efficient three-dimensional mixing by the synergistic action of the main stirrer (impeller + toothed disc) and the rotating nozzle, avoiding stratification or sedimentation.

[0021] In some technical solutions of this utility model, the circulating cooling structure includes a constant temperature water jacket 12 installed on the outside of the cylindrical structure 4. An inlet 5 is installed on one side of the constant temperature water jacket 12, and an outlet 13 is installed on the other side. The horizontal height of the inlet 5 is lower than that of the outlet 13. The constant temperature water jacket 12 encloses the cylindrical structure 4, forming a cooling space around the circumference of the cylindrical structure 4 for heat exchange. The low-position design of the inlet 5 ensures that cold water fully fills the jacket, while the high-position outlet utilizes thermal convection to enhance cooling efficiency. When constant temperature water flows into the jacket from the low-position inlet 5, it absorbs heat through the cylindrical wall and is discharged from the high-position outlet 13, forming a counter-flow jacket design (low inlet, high outlet) that extends the residence time of the cooling medium, enhances heat exchange uniformity, and avoids localized overcooling / overheating.

[0022] In some technical solutions of this utility model, the number of nozzle structures 9 is at least 3 sets. The nozzle structures 9 are arranged around the side wall of the cover plate 3, and each nozzle structure 9 is rotatably arranged on the side wall of the cover plate 3 through a bearing structure. After the three or more sets of rotating nozzles move in a cross motion, a 360° coverage area is formed, reducing mixing dead angles and improving the subsequent cleaning effect on the cylinder structure 4.

[0023] Preferably, the nozzle structure 9 is a high-pressure nozzle.

[0024] In some technical solutions of this utility model, the second drive mechanism includes a synchronous belt 19. A shielding cover 20 is provided on the inner side of the cover plate 3, forming an installation space between the shielding cover 20 and the cover plate 3. The synchronous belt 19 is installed within this installation space. A nozzle rotation motor 2 is provided on the outer wall of the cover plate 3. A drive gear 22 is provided at the output end of the nozzle rotation motor 2. Synchronous gears 21 are provided at the ends of the nozzle structures 9 placed within the installation space. The synchronous belt 19 is sleeved on the outside of several synchronous gears 21 and then connected to them for transmission. The drive gears 22 mesh with the synchronous belt 19. The synchronous belt 19 transmission distributes the power of a single motor to multiple nozzles, causing at least three sets of nozzles to surround the cylinder wall. The nozzle rotation motor 2 drives the drive gears 22, and through the synchronous belt 19, drives the synchronous gears 21 of all nozzles to rotate, causing the three nozzle structures 9 to rotate and form an intersecting area, eliminating mixing dead zones. The synchronous belt 19 transmission ensures consistent nozzle rotation speed and uniform spray coverage.

[0025] When tap water flows through the cleaning inlet 5 to the high-pressure nozzle, the nozzle rotation motor 2 drives the three high-pressure nozzles to rotate via the synchronous belt 19, thus rinsing the inner wall of the cylinder and the stirring components.

[0026] In some technical solutions of this utility model, the cylindrical structure 4 is provided with several baffles 16. When the propulsion three-bladed impeller and the toothed dispersion disk 14 rotate at high speed, the baffles eliminate the vortices generated by the graphite emulsion turbulence, improve the shear performance of the toothed dispersion disk 14, and the baffles 16 block the tangential flow, converting it into axial / radial flow, enhancing the turbulence intensity, improving the shear rate and mixing efficiency, and reducing particle stratification caused by the "vortex effect".

[0027] In some technical solutions of this utility model, a pH detection sensor 7 and a mixing detection sensor 8 are provided on the outer wall of the cylinder structure 4. The pH sensor monitors the acidity and alkalinity, the mixing sensor provides feedback on uniformity, and the data is linked to the control system to achieve closed-loop intelligent regulation, improve product qualification rate, and reduce manual intervention.

[0028] Preferably, the hybrid detection sensor 8 is a three-in-one detection sensor for temperature, viscosity and density, which monitors various parameters of graphite emulsion.

[0029] In some technical solutions of this utility model, a pneumatic butterfly valve 6 is installed at the bottom of the cylindrical structure 4. This allows for rapid, airtight discharge, preventing leakage. The valve body diameter is matched to fluids with high solids content, improving maintenance efficiency. The pneumatic butterfly valve 6 has a fast response time, making it suitable for high-frequency automated production.

[0030] In some technical solutions of this utility model, the side wall of the cover plate 3 is provided with a pure water inlet 10 and an ammonia inlet 11. Pure water / ammonia is added precisely through independent inlets, preventing ammonia from directly contacting metal parts and extending the equipment's lifespan.

[0031] Preferably, a sampling port 18 is provided on the top of the cover, and the sampling port 18 is covered by the sampling cover.

[0032] The working process of the graphite emulsion mixing device is as follows: First, input the required graphite emulsion formula, such as viscosity, density, pH value, and required graphite emulsion volume, on the operation screen. Input the formula for colloidal graphite emulsion. Pour a certain amount of colloidal graphite emulsion into the cylinder through sampling port 18. Start the metering pump and input the corresponding amount of pure water into the cylinder through pure water inlet 10. Water at a certain temperature is introduced into the constant temperature water jacket 12 around the cylinder structure 4. The stirring shaft starts to rotate at high speed. After a certain stirring time (density, viscosity, and particle size reach the required requirements), the stirring shaft speed is reduced to low speed operation. Start the metering pump and input the corresponding amount of ammonia water through ammonia water inlet 11 to adjust the pH value of the graphite emulsion until the required pH range is reached. When all indicators of the graphite emulsion meet the requirements, the system issues an audible and visual alarm to remind the staff that the graphite emulsion has been prepared. The graphite emulsion in the cylinder is released through the pneumatic butterfly valve 6. When it is necessary to clean the cylinder, the system controls the pneumatic ball valve to open. Tap water flows through the inlet 5 to the high-pressure nozzle. The nozzle rotation motor 2 starts, causing the nozzle to rotate slowly, rinsing the cylinder, rotating shaft, and blades.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
