Description

Technical Field

[0001] This utility model relates to the technical field of equipment for preparing whisker-shaped anhydrous magnesium carbonate, specifically a device for preparing a green and efficient flame-retardant material of whisker-shaped anhydrous magnesium carbonate. Background Technology

[0002] Whisker-shaped anhydrous magnesium carbonate is a special form of anhydrous magnesium carbonate crystal, usually existing in fibrous or needle-like structures. It has high specific surface area, excellent dispersibility and thermal stability, and is widely used in flame retardant, adsorption and material reinforcement fields. In nature, it exists in the form of magnesite, but in industrial preparation, high-purity products are obtained through the preparation equipment of whisker-shaped anhydrous magnesium carbonate green and efficient flame retardant materials.

[0003] The existing preparation device for whisker-shaped anhydrous magnesium carbonate green and efficient flame retardant material involves placing the raw material of whisker-shaped anhydrous magnesium carbonate into a preparation cylinder, and mixing the raw material of whisker-shaped anhydrous magnesium carbonate by rotating a stirring rod driven by a motor. After the raw material of whisker-shaped anhydrous magnesium carbonate is fully mixed and reacted, the resulting solution containing magnesium carbonate crystals is filtered, and the filtered magnesium carbonate crystals are washed and dried to obtain high-purity whisker-shaped anhydrous magnesium carbonate.

[0004] Existing apparatuses for preparing whisker-shaped anhydrous magnesium carbonate green and efficient flame retardant materials only use a motor-driven stirring rod to rotate unidirectionally to mix the raw materials. This single stirring method results in a slow mixing rate of the raw materials, which affects the mixing reaction speed and requires a long time for the raw materials to fully react, thus impacting the preparation efficiency. Therefore, we propose an apparatus for preparing whisker-shaped anhydrous magnesium carbonate green and efficient flame retardant materials. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a preparation device for a green and efficient flame-retardant material of whisker-shaped anhydrous magnesium carbonate. Through a stirring mechanism, a motor drives a rotating drum to rotate, and then a linkage component drives two sets of upper and lower stirring blades and two sets of left and right stirring blades to rotate in opposite directions. This generates vertical convection and enhances horizontal circulation inside the preparation drum, allowing the raw materials for preparing whisker-shaped anhydrous magnesium carbonate to fully contact and mix inside the preparation drum, thereby improving the reaction rate of the raw materials for preparing whisker-shaped anhydrous magnesium carbonate and thus improving the preparation efficiency of whisker-shaped anhydrous magnesium carbonate. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a preparation device for a whisker-like anhydrous magnesium carbonate green high-efficiency flame retardant material, comprising a preparation cylinder, wherein a mounting frame is fixedly connected to the upper surface of the preparation cylinder, and a stirring mechanism is also included;

[0007] The stirring mechanism includes a rotating drum, a fixed rod, a first rotating rod, a second rotating rod, a mounting base, a linkage assembly, and a transmission assembly.

A fixed rod is fixedly connected to the lower interior of the mounting frame, located inside the rotating drum. The first rotating rod is rotatably connected to both sides of the rotating drum's outer surface via a first sealed bearing. The second rotating rod is rotatably connected to the lower end of the rotating drum via a second sealed bearing. A mounting base is fixedly connected to the lower end of the second rotating rod. Uniformly distributed stirring blades are fixedly connected to the outer surface of the first rotating rod. The outer surfaces of the rotating drum and the mounting base are also fixed... The drum is connected to a uniformly distributed stirring blade, and a linkage assembly is fixedly connected inside the drum. A transmission assembly is fixedly connected to the upper end of the drum. Through the stirring mechanism, the motor drives the drum to rotate. Then, the linkage assembly drives the upper and lower stirring blades and the left and right stirring blades to rotate in opposite directions. This generates vertical convection and enhances horizontal circulation inside the drum, allowing the raw materials for preparing whisker-shaped anhydrous magnesium carbonate to fully contact and mix inside the drum, thereby increasing the reaction rate of the raw materials for preparing whisker-shaped anhydrous magnesium carbonate and thus improving the preparation efficiency of whisker-shaped anhydrous magnesium carbonate.

[0008] Furthermore, a control switch is provided on the outside of the preparation cylinder, and the input terminal of the control switch is electrically connected to an external power source to control the operation of the motor.

[0009] Furthermore, the linkage assembly includes bevel gear one, bevel gear two, and bevel gear three. Bevel gear one is fixedly connected to the lower end of the fixed rod. Bevel gear two is fixedly connected to the end of the rotating rod one located inside the rotating drum and near the middle of the rotating drum. Bevel gear three is fixedly connected to the upper end of the rotating rod two. Bevel gear two is meshed with bevel gear one and bevel gear three respectively, so that the two sets of stirring blades one and the two sets of stirring blades two rotate in opposite directions.

[0010] Furthermore, the transmission assembly includes a rotating shaft, a gear, and an external gear ring. The external gear ring is fixedly connected to the upper end of the rotating cylinder. The rotating shaft is rotatably connected to the inner left side of the mounting bracket. A gear is fixedly connected to the lower side of the outer surface of the rotating shaft. The gear meshes with the external gear ring to transmit driving force.

[0011] Furthermore, a motor is fixedly connected to the upper end of the mounting bracket, the lower end of the motor's output shaft is fixedly connected to the upper end of the rotating shaft, and the input end of the motor is electrically connected to the output end of the control switch to provide driving force.

[0012] Furthermore, the upper surface of the preparation cylinder is fixedly connected with a feed inlet, and the lower surface of the preparation cylinder is fixedly connected with a discharge outlet, which facilitates the feeding and discharging of materials.

[0013] Furthermore, a transparent pipe is fixedly connected to the left side of the outer surface of the preparation cylinder. Both the upper and lower ends of the transparent pipe are connected to the preparation cylinder, allowing observation of the amount of raw material inside the preparation cylinder through the transparent pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The preparation device for this whisker-like anhydrous magnesium carbonate green and efficient flame retardant material has the following advantages:

[0015] The stirring mechanism drives the rotating drum to rotate, and then the linkage component drives the upper and lower sets of stirring blades one and the left and right sets of stirring blades two to rotate in opposite directions.

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] Please see Figure 1-4 This embodiment provides a technical solution: a preparation device for a whisker-shaped anhydrous magnesium carbonate green and efficient flame retardant material, including a preparation cylinder 1. A mounting frame 2 is fixedly connected to the upper surface of the preparation cylinder 1. Inlets 4 are fixedly connected to the upper surface of the preparation cylinder 1. The raw material for producing whisker-shaped anhydrous magnesium carbonate is fed into the preparation cylinder 1 through the inlets 4. An outlet 6 is fixedly connected to the lower surface of the preparation cylinder 1 (a valve is connected in series in the middle of the outlet 6). After the raw material for producing whisker-shaped anhydrous magnesium carbonate has reacted inside the preparation cylinder 1, the valve is opened, and the raw material is discharged through the outlet. The material is discharged from the outlet 6, and the raw material for the production of whisker-shaped anhydrous magnesium carbonate after the mixed reaction is filtered to obtain crystalline solid. The crystalline solid is then washed and dried to obtain whisker-shaped anhydrous magnesium carbonate. A transparent pipe 5 is fixedly connected to the left side of the outer surface of the preparation cylinder 1. The transparent pipe 5 can be a transparent glass pipe. Both the upper and lower ends of the transparent pipe 5 are connected to the preparation cylinder 1. The liquid level inside the transparent pipe 5 is observed to display the liquid level inside the preparation cylinder 1. A control switch 7 is set on the outside of the preparation cylinder 1. The input end of the control switch 7 is electrically connected to an external power source. A stirring mechanism 8 is also included.

[0023] The stirring mechanism 8 includes a rotating drum 81, a fixed rod 82, a first rotating rod 83, a second rotating rod 84, a mounting base 85, a linkage assembly 86, and a transmission assembly 87. The rotating drum 81 is rotatably connected to the interior of the mounting frame 2, and the lower end of the rotating drum 81 extends into the interior of the preparation drum 1. The fixed rod 82 is fixedly connected to the lower side of the interior of the mounting frame 2, and the fixed rod 82 is located inside the rotating drum 81. The first rotating rod 83 is rotatably connected to both the left and right sides of the outer surface of the rotating drum 81 through a first sealed bearing. The second rotating rod 84 is rotatably connected to the lower end of the rotating drum 81 through a second sealed bearing. The lower end of the second rotating rod 84 is fixedly connected to the mounting base 85. The outer surface of the first rotating rod 83 is fixedly connected with uniformly distributed stirring blades 10. The outer surfaces of the rotating drum 81 and the mounting base 85 are also fixedly connected with uniformly distributed stirring blades 10. The rotating drum 81 is equipped with a stirring blade 9. A linkage assembly 86 is fixedly connected inside the rotating drum 81. The linkage assembly 86 includes a bevel gear 861, a bevel gear 862, and a bevel gear 863. The bevel gear 861 is fixedly connected to the lower end of the fixed rod 82. The end of the rotating rod 83 located inside the rotating drum 81 and near the middle of the drum 81 is fixedly connected to the bevel gear 862. The upper end of the rotating rod 84 is fixedly connected to the bevel gear 863. The bevel gear 862 meshes with both the bevel gear 861 and the bevel gear 863. A transmission assembly 87 is fixedly connected to the upper end of the rotating drum 81. The transmission assembly 87 includes a rotating shaft 871, a gear 872, and an external gear ring 873. The external gear ring 873 is fixedly connected to the upper end of the rotating drum 81. The mounting bracket 2 rotates to the left. A rotating shaft 871 is connected, and a gear 872 is fixedly connected to the lower side of the outer surface of the rotating shaft 871. The gear 872 meshes with an external gear ring 873. A motor 3 is fixedly connected to the upper end of the mounting bracket 2. The lower end of the output shaft of the motor 3 is fixedly connected to the upper end of the rotating shaft 871. The input end of the motor 3 is electrically connected to the output end of the control switch 7. When the control switch 7 is operated, the motor 3 is started. The output shaft of the motor 3 rotates, causing the rotating shaft 871 to rotate, which in turn causes the gear 872 to rotate, which in turn causes the external gear ring 873 to rotate, which in turn causes the rotating drum 81 to rotate, which in turn causes the upper stirring blade 9 to rotate, which in turn causes the rotating rod 83 to rotate around the central axis of the rotating drum 81, which in turn causes the bevel gear 862 to rotate around the central axis of the rotating drum 81. Since the bevel gear 861 is fixed, the bevel gear 862 rotates around the central axis of the rotating drum 81. During the rotation around the central axis of the rotating drum 81, the rotating shaft 83 rotates in opposite directions, causing the stirring blades 10 on both sides to rotate. At this time, the bevel gears 862 drive the bevel gears 863 to rotate, causing the rotating shaft 84 to rotate, which in turn drives the mounting base 85 to rotate, causing the stirring blade 9 on the lower side to rotate. The stirring blades 9 on the upper and lower sides rotate in opposite directions, as do the stirring blades 10 on the left and right sides. This fully stirs the raw material for producing whisker-shaped anhydrous magnesium carbonate, allowing it to tumble in three-dimensional space. This significantly reduces dead zones at the edges and bottom of the drum, increases the contact area of ​​various raw materials, and thus improves the reaction rate.

[0024] The working principle of the preparation device for whisker-shaped anhydrous magnesium carbonate green high-efficiency flame retardant material provided by this utility model is as follows: When preparing whisker-shaped anhydrous magnesium carbonate green high-efficiency flame retardant material using this preparation device, the raw material for whisker-shaped anhydrous magnesium carbonate is fed into the preparation cylinder 1 through the feed inlet 4. By observing the liquid level inside the transparent pipe 5, the liquid level inside the preparation cylinder 1 is displayed. The control switch 7 is operated to start the motor 3. The output shaft of the motor 3 rotates, driving the rotating shaft 871 to rotate, causing the gear 872 to rotate, driving the external gear ring 873 to rotate, causing the rotating cylinder 81 to rotate, causing the upper stirring plate 9 to rotate, driving the rotating rod 83 to rotate around the central axis of the rotating cylinder 81, causing the bevel gear 862 to rotate around the central axis of the rotating cylinder 81. Since the bevel gear 861 is fixed, the bevel gear 862 rotates on its own during the rotation around the central axis of the rotating cylinder 81, and the bevel gears 862 on both the left and right sides rotate. The rotation directions are reversed, causing the rotating rod 83 to rotate, which in turn drives the stirring plates 10 on both sides to rotate. At this time, the bevel gear 862 drives the bevel gear 863 to rotate, causing the rotating rod 84 to rotate, which in turn drives the mounting base 85 to rotate, causing the stirring plate 9 on the lower side to rotate. At this time, the rotation directions of the stirring plates 9 on the upper and lower sides are opposite, and the rotation directions of the stirring plates 10 on the left and right sides are opposite. This fully stirs the raw material for producing whisker-shaped anhydrous magnesium carbonate, allowing the raw material to be fully turned over in three-dimensional space. This significantly reduces the dead areas at the edges and bottom of the preparation cylinder, increases the contact area of ​​various raw materials, and thus increases the reaction rate. After the raw material for producing whisker-shaped anhydrous magnesium carbonate has reacted inside the preparation cylinder 1, it is discharged through the discharge port 6. The mixed and reacted raw material is then filtered to obtain crystalline solids, which are then washed and dried to obtain whisker-shaped anhydrous magnesium carbonate.

[0025] It is worth noting that the motor 3 disclosed in the above embodiments is YE2-80M1-2-B3, and the control switch 7 is provided with a control button corresponding to the motor 3 and used to control its switching.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
