Description

Technical Field

[0001] This utility model relates to the field of high-speed mixer technology, specifically to a high-speed mixer for magnesium slag and polyolefins. Background Technology

[0002] The mixing of magnesium slag and polyolefins is an important step in the preparation of functional composite materials. Its core objective is to achieve uniform dispersion of inorganic magnesium slag and organic polyolefins in order to improve material properties (such as mechanical strength, heat resistance, cost control, etc.). External forces such as stirring and shearing are used to mix the materials as a whole.

[0003] In existing technologies, the melt blending method is generally used to mix magnesium slag with polyolefins. The general principle is that the polyolefin, in a heated and molten state, is mixed with the pretreated magnesium slag through mechanical shearing. Before the polyolefin melts, the magnesium slag and polyolefin particles (or powder) are usually pre-mixed by low-speed stirring to prepare for subsequent melt blending. A high-speed mixer can be used for mixing. Through the rotation of the spiral blades, the material at the bottom is lifted upward along the conical surface. Under the action of centrifugal force, the material rises along the conical wall of the fixed mixing tank and is in a swirling motion, forming a vortex motion. It is easy to mix materials of different densities evenly in a short time. However, since this high-speed mixer lacks a heating structure, it is difficult to fully mix the magnesium slag and polyolefin particles by stirring with a single stirring blade.

Two stirring assemblies are rotatably mounted on the turntable for stirring magnesium slag and polyolefin particles in the mixing cylinder. The driving assembly is mounted on the turntable and the cover for driving the two stirring assemblies to rotate. The heating mechanism is mounted on the mixing cylinder for heating the inner wall of the mixing cylinder.

[0008] Furthermore, the stirring assembly includes a limiting plate, a rotating shaft, and multiple spiral blades. The limiting plate is rotatably disposed within the turntable. One end of the rotating shaft passes through one end of the turntable and is coaxially and fixedly connected to the limiting plate. The multiple spiral blades are longitudinally disposed on the rotating shaft.

[0009] Furthermore, the drive assembly includes gears and a second motor. The gears are mounted on both of the two rotating shafts and are coaxially and fixedly connected to the gears. The two gears mesh. The second motor is mounted on the cover. The output end of the second motor passes through the cover and the turntable and is coaxially and fixedly connected to a limiting plate.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a high-speed mixer for magnesium slag and polyolefins, which has the following beneficial effects:

[0015] In this invention, through the cooperation of a turntable, stirring components, drive components, and heating mechanism, the first motor and the second motor drive the two stirring components to revolve while simultaneously enabling the two rotating shafts to drive multiple spiral blades to rotate independently. This allows for thorough stirring and shearing of magnesium slag and polyolefin particles. Furthermore, by opening the valve and starting the circulation pump, hot water is drawn from the hot water tank and transferred through the outlet pipe to the spiral tube, where it circulates. This heats the inner wall of the mixing cylinder, raising the temperature of the polyolefin particles while they are being stirred, thus improving the mixing effect. Therefore, this high-speed mixer for magnesium slag and polyolefin addresses the problem mentioned in the background art: the prior art lacks a heating structure, and the stirring of a single stirring blade makes it difficult to fully mix magnesium slag and polyolefin particles.

[0022] 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.

[0023] Example

[0024] Please see Figures 1 to 5 A high-speed mixer for magnesium slag and polyolefin includes a high-speed mixer body 1, which includes a mixing cylinder 2. A cover 3 is provided at the top of the mixing cylinder 2. The cover 3 is lifted and lowered at the top of the mixing cylinder 2 by a cylinder. The mixer also includes a turntable 4, a stirring assembly, a driving assembly, and a heating mechanism.

[0025] A turntable 4 is rotatably mounted on one end of a cover 3 via a first motor 16. The first motor 16 is mounted on the cover 3, and its output end is coaxially and fixedly connected to one end of the turntable 4. Two stirring components are rotatably mounted on the turntable 4 for stirring magnesium slag and polyolefin particles in the mixing cylinder 2. The stirring components include a limiting plate 5, a rotating shaft 6, and multiple spiral blades 7. The limiting plate 5 is rotatably mounted inside the turntable 4, and a limiting groove is provided inside the turntable 4 to cooperate with the limiting plate 5. The limiting plate 5 is cylindrical and is rotatably mounted in the limiting groove. One end of the rotating shaft 6 passes through one end of the turntable 4 and is coaxially and fixedly connected to the limiting plate 5. The first motor 16 rotates in coordination with the turntable 4. Multiple spiral blades 7 are longitudinally mounted on the rotating shaft 6. By starting the first motor 16, the output end of the first motor 16 rotates, driving the turntable 4 to rotate. The rotation of the turntable 4 drives the two stirring components to rotate around the axis of the turntable 4, which can stir the magnesium slag and polyolefin particles in the mixing cylinder 2.

[0026] The drive assembly is mounted on the turntable 4 and the cover 3 to drive the two stirring components to rotate. The drive assembly includes a gear 8 and a second motor 9. Gears 8 are mounted on both rotating shafts 6 and are coaxially fixedly connected to the gears 8. The two gears 8 mesh. A cavity is opened in the turntable 4, and the two gears 8 are located in the cavity. The second motor 9 is mounted on the cover 3. The output end of the second motor 9 passes through the cover 3 and the turntable 4 and is coaxially fixedly connected to a limiting plate 5. By starting the second motor 9, the output end of the second motor 9 rotates, driving the limiting plate 5 to rotate. The limiting plate 5 drives the rotating shaft 6 that it is cooperating with to rotate. The rotation of the rotating shaft 6 drives the gear 8 that it is fixedly connected to to rotate. The rotation of the gear 8 drives the other gear 8 to rotate. The other gear 8 drives the other rotating shaft 6 to rotate. In this way, the two rotating shafts 6 are driven to rotate, driving multiple spiral blades 7 to rotate. With the rotation of the turntable 4, the two stirring components can revolve around each other while the two rotating shafts 6 drive multiple spiral blades 7 to rotate on their own axis. This can fully stir and shear magnesium slag and polyolefin particles.

[0027] A heating mechanism is installed on the mixing cylinder 2 to heat the inner wall of the mixing cylinder 2. The heating mechanism includes a hot water tank 10, a water outlet pipe 11, a valve 17, a spiral pipe 13, and a return pipe 14. The hot water tank 10 is installed on the outer wall of the mixing cylinder 2. One end of the water outlet pipe 11 passes through the hot water tank 10 and is connected to it. A circulation pump 12 is installed on the mixing cylinder 2. The circulation pump 12 divides the water outlet pipe 11 into two ends. The input end and output end of the circulation pump 12 are respectively connected to the two sections of the water outlet pipe 11. A valve 17 is installed on the water outlet pipe 11 on the output end side of the circulation pump 12. A heating space is opened on the mixing cylinder 2. The spiral pipe 13 is sleeved in the heating space. One end of the spiral pipe 13 is connected to the other end of the water outlet pipe 11. The two ends of the return pipe 14 are respectively connected to the other end of the spiral pipe 13 and the hot water tank 10. The mixing cylinder 2 is connected at the top and is equipped with a support base 15 to support and fix the return pipe 14. In order to prevent the temperature inside the mixing cylinder 2 from dropping too quickly, a heat insulation layer is provided on the outer wall of the mixing cylinder 2. It should be added that the hot water tank 10 is used in conjunction with an external heating device (the water source is heated by the heat generated by the combustion in the boiler chamber and transferred to the hot water tank 10 for storage). The hot water tank 10 is also equipped with a heat insulation layer. By opening the valve 17 and starting the circulation pump 12, the circulation pump 12 draws the hot water from the hot water tank 10 and transfers it to the spiral tube 13 through the outlet pipe 11 and circulates in the spiral tube 13. The spiral tube 13 is close to the inner wall of the heating space, thus heating the inner wall of the mixing cylinder 2. When the magnesium slag and polyolefin particles are stirred, the temperature of the polyolefin particles is increased, which can improve the mixing effect.

[0028] It should be further explained that the first motor 16 and the second motor 9 in this embodiment are conventional devices known to those skilled in the art and available on the market. The model can be selected or customized according to actual needs. In this patent, we only use them without improving their structure and function. For those skilled in the art, the setting method, installation method and electrical connection method can be debugged and operated according to the requirements of the instruction manual, and will not be described in detail here. The first motor 16 and the second motor 9 are equipped with matching control switches. The installation position of the control switches can be selected according to the actual use requirements to facilitate the operation and control of the operator. At the same time, the motors need to be connected to the forward and reverse circuit before use for forward and reverse operation. As for the forward and reverse use of the motors, according to the patent disclosed in patent number CN109889124A, the forward and reverse operation of the motors is a well-known technology to those skilled in the art, and the technology is very mature and can be implemented.

[0029] Working principle: When mixing magnesium slag and polyolefin particles, the high-speed mixer for magnesium slag and polyolefin particles is used. The magnesium slag and polyolefin particles are placed into the mixing cylinder 2, and the first motor 16 and the second motor 9 are started at the same time. The output end of the first motor 16 rotates, which drives the turntable 4 to rotate. The rotation of the turntable 4 drives the two stirring components to rotate around the axis of the turntable 4, which can stir the magnesium slag and polyolefin particles in the mixing cylinder 2. The output end of the second motor 9 rotates, which drives a limiting plate 5 to rotate. The limiting plate 5 drives the rotating shaft 6 that cooperates with it to rotate. The rotation of the rotating shaft 6 drives the gear 8 that is fixed to it to rotate. The rotation of the gear 8 drives another gear 8 to rotate. The other gear 8 drives another rotating shaft 6 to rotate. In this way, the two rotating shafts 6 are driven to rotate, which drives multiple spiral blades 7 to rotate. With the rotation of the turntable 4, the two stirring components can revolve around the turntable, and the two rotating shafts 6 can drive multiple spiral blades 7 to rotate on their own axis, which can fully stir and shear the magnesium slag and polyolefin particles.

[0030] While the magnesium slag and polyolefin particles are being mixed, valve 17 is opened and circulation pump 12 is started. Circulation pump 12 draws hot water from hot water tank 10 and transfers it through outlet pipe 11 to spiral tube 13, where it circulates. Spiral tube 13 is in close contact with the inner wall of the heating space, thus heating the inner wall of mixing cylinder 2. This raises the temperature of polyolefin particles while the magnesium slag and polyolefin particles are being stirred, thereby improving the mixing effect.

[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 and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
