Description

Technical Field

[0001] This utility model relates to the field of blending kettle technology, specifically a mixing kettle for producing lithium-based grease. Background Technology

[0002] Lithium-based grease is made by thickening mineral oil with lithium hydroxy fatty acid soap and adding various additives such as antioxidants, rust inhibitors, corrosion inhibitors, extreme pressure anti-wear agents, etc. Lithium-based grease has excellent water resistance, mechanical stability, extreme pressure anti-wear performance, water resistance and pumpability, rust prevention and oxidation stability. Lithium-based grease can also exert its superior lubrication performance under extremely harsh operating conditions. In the production process of lithium-based grease, various additives need to be mixed and stirred inside the mixing tank.

[0003] Currently, most mixing reactors for preparing lithium-based grease have only one stirring shaft. When a single-shaft stirrer rotates, the reactants can only rotate in one direction, resulting in inefficient mixing. Therefore, we propose a mixing reactor for producing lithium-based grease. Utility Model Content

[0004] This invention provides a mixing and blending kettle for producing lithium-based grease, which has the advantage of thorough stirring and solves the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A mixing and blending kettle for producing lithium-based grease is designed, including a tank body with a detachable lid on the top, a support tube shaft rotatably provided in the middle of the lid, both ends of the support tube shaft being located outside the lid, multiple connecting arms are installed on the bottom side of the support tube shaft, and each connecting arm is provided with a support rod at its end. Multiple spiral stirring blades are installed outside the space enclosed by the support rods, and an intermediate shaft is rotatably provided inside the support tube shaft. The tops of the intermediate shaft and the support tube shaft are driven to rotate by a driving device, and the bottom of the intermediate shaft extends into the bottom of the tank body. Spiral blades are provided on the surface of the intermediate shaft, and the spiral blades are coaxially located inside a sleeve. The sleeve and the support rods are connected by connecting rods, and at least one stirring plate is also provided on the intermediate shaft.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1 to 6 This utility model provides a technical solution: a mixing and blending kettle for producing lithium-based grease, comprising a tank body 1, with multiple support legs 8 at the bottom of the tank body 1 supporting the ground, and a detachable lid 2 on the top of the tank body 1, the tank body 1 and the lid 2 being connected by a latch or bolts. A feeding port 22 is provided on one side of the top of the lid 2, the feeding port 22 being sealed by a detachable cover, the cover and the feeding port 22 also being connected by a latch, facilitating disassembly and installation. In actual use, the raw material for the lithium-based grease to be produced is poured into the tank body 1 through the feeding port 22 for stirring and reaction. After stirring is complete, it can be discharged from the discharge valve 7 located at the bottom of the tank body 1.

[0025] like Figure 2 and Figure 3 As shown, a support 4 is provided on the side of the tank 1. The bottom of the support 4 is connected to the mounting frame 21. The mounting frame 21 is horizontal and connected to the side of the tank 1. To provide better support for the mounting frame 21 and prevent the tank 1 from becoming unstable, a stabilizing leg 23 is provided at the bottom of the mounting frame 21. The stabilizing leg 23 and the supporting leg 8 are supported on the ground together. Figure 3 and Figure 4 As shown, two motors 9 are installed on the bracket 4. The motors 9 are located at the top of the bracket 4, and each motor 9 has a pulley installed on its top shaft. A support tube shaft 11 is rotatably mounted in the middle of the can lid 2, meaning the two are coaxially arranged. Both ends of the support tube shaft 11 are located outside the can lid 2. An intermediate shaft 10 is rotatably mounted inside the support tube shaft 11. The tops of both the intermediate shaft 10 and the support tube shaft 11 are equipped with pulleys corresponding to two motors 9, respectively, and the pulleys are connected by a belt. The motors 9, pulleys, belt, and bracket 4 constitute the driving device in this application. Under the drive of the driving device, the intermediate shaft 10 and the support tube shaft 11 can rotate independently, such as... Figure 1 and Figure 2 As shown, a protective cover 3 is provided on the drive unit, and the protective cover 3 is installed on the top of the bracket 4 and the can lid 2; Furthermore, the lower end of the support tube shaft 11 is located at the top of the tank body 1, and multiple connecting arms 12 are installed on the bottom side of the support tube shaft 11. The connecting arms 12 rotate with the support tube shaft 11. Each connecting arm 12 has a support rod 13 at its end, and the support rod 13 is parallel to the intermediate shaft 10. In actual installation, a flange seat is provided at the end of the connecting arm 12 near the support tube shaft 11. The flange seat is fastened to the side of the support tube shaft 11 by bolts, and the top of the support rod 13 is placed inside the end of the connecting arm 12. A nut is threaded on the top of the support rod 13, that is, the support rod 13 and the connecting arm 12 are fastened together by the nut. In actual use, the support tube shaft 11 rotates independently, and the intermediate shaft 10 also rotates independently. It should be emphasized that the space enclosed by the multiple support rods 13 is coaxial with the tank body 1, and multiple spiral stirring blades 14 are installed outside this space. There are at least two sets of spiral stirring blades 14, which are arranged in layers on the support rods 13, with no less than two spiral stirring blades 14 in each set. It should be noted that, in order to increase the stirring effect, the spiral stirring blades 14 of adjacent layers can rotate in opposite directions. In this way, when the spiral stirring blades 14 rotate, they can quickly stir the reactants. Moreover, the gap between the spiral stirring blades 14 and the inner wall of the tank body 1 is very small or has a clearance fit, so that when the spiral stirring blades 14 rotate, they can scrape off the reactants adhering to the surface of the tank body 1, and at the same time, they can also bring the stirred reactants closer to the central axis 10. The length of the spiral stirring blade 14 here can span at least two support rods 13. When the spiral stirring blade 14 is installed on the side of the support rod 13, multiple support rods 13 can form a whole. At the same time, the bottom of the support rods 13 are all installed on the support ring 18, which further improves the strength between the support rods 13. Multiple stirring blades 19 are installed on the inner surface of the support ring 18. The gap between the stirring blades 19 and the bottom of the tank 1 is very small or clearance fit, which allows the stirring blades 19 to scoop up the reactants at the bottom of the tank 1 when rotating.

[0026] Furthermore, as described above, the lower end of the support shaft 11 is located only at the top of the tank 1, but the bottom of the intermediate shaft 10 extends into the bottom of the tank 1. A spiral blade 20 is provided on the surface of the intermediate shaft 10, and the spiral blade 20 is coaxially located inside the sleeve 16. The sleeve 16 and the support rod 13 are connected by connecting rods 15. Here, the sleeve 16 can be understood as a pump casing, and the spiral blade 20 as a conduit impeller. When the spiral blade 20 rotates with the intermediate shaft 10, it can drive the reactants to flow rapidly downwards along the sleeve 16, thereby increasing the flow and tumbling of the reactants. At least one stirring disc 17 is also provided on the intermediate shaft 10. The stirring disc 17 is also called a dispersing disc. Figure 5 and Figure 6 As shown, the stirring disk 17 is located below the spiral vane 20, so the reactants flowing from the direction of the spiral vane 20 directly contact the stirring disk 17. The rotating stirring disk 17 further accelerates the tumbling and mixing of the reactants. There are at least two stirring disks 17. It should be emphasized that the spiral vane 20 can be replaced by an impeller or blades.

[0027] Based on the above embodiments, when using the mixing vessel proposed in this application, the height of the reactants should exceed the spiral blade 20 and be lower than the connecting arm 12. Then, the feeding port 22 is sealed. At this time, the motor 9 can be controlled to rotate. The speed of the intermediate shaft 10 should be fast so that the stirring plate 17 and the spiral blade 20 have a high speed, while the support tube shaft 11 rotates slowly to avoid the support rod 13 being subjected to excessive force and causing bending deformation. At the same time, the spiral stirring blade 14 drives the reactants to detach from the inner wall of the tank 1 and stirs the reactants, while also driving the reactants to move away from the central axis 10. Meanwhile, the spiral blade 20 drives the reactants to impact the stirring plate 17 quickly, causing the stirring plate 17 to stir the reactants rapidly.

[0028] Based on the above embodiments, further optimization is possible. A control cabinet 5 is provided on the side of the mounting bracket 21. The surface of the control cabinet 5 is provided with control buttons and a display. A controller is provided inside the control cabinet 5. The controller is specifically a PLC control system, which is widely used in the field of intelligent control. The controller is electrically connected to the motor 9. A liquid level sensor is also provided on the tank 1 to detect the liquid level height inside the tank. In practice, a heating device can be installed on the surface of the tank 1 to heat the tank to a preset temperature, which facilitates the rapid reaction of the reactants; The top of the can lid 2 has multiple mounting points (such as...). Figure 1 The holes (pointed to by the middle arrow A) are used to install pressure detectors, pressure relief valves, temperature probes, or cleaning pipes, etc. The control buttons, display, pressure detectors, level sensors, and heating devices are electrically connected to the controller.

[0029] Based on the above embodiments, in order to further improve the stability of the bracket 4, reinforcing frames 6 can be provided on both sides of the bracket 4. The reinforcing frames 6 are tilted downward and connected to the support legs 8.

[0030] 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.
