Technical Field

[0001] This utility model belongs to the technical field of chemical production equipment, specifically an alumina batching, stirring and dispersing device. Background Technology

[0002] In industrial production, the batching, mixing, and dispersion processes of alumina powder materials have a significant impact on product quality. A patent document with publication number CN107970856B discloses a high-efficiency dispersion device, which includes a batching cylinder, a mixing device, a dispersion device, a material conveying power device, and a grinding device. It processes the material separately through the mixing and dispersion devices, and combines this with a ball mill to achieve cyclic grinding and dispersion of the material, thereby improving dispersion effect and mixing efficiency. However, this device involves multiple independent functional modules, resulting in a complex structural design, high equipment cost, and certain difficulties in daily maintenance. Furthermore, this solution does not propose special treatment measures for high-density or easily agglomerated materials, which may lead to incomplete dispersion or uneven mixing when processing high-density powder materials such as alumina.

[0003] Therefore, there is an urgent need to design an alumina batching and dispersing device to solve the problems of incomplete dispersion and uneven mixing mentioned above, while optimizing the structural design to reduce equipment costs and maintenance difficulty. Utility Model Content

One end of the drive shaft is connected to the output end of the drive motor via a pin, and the other end is connected to the gear. The drive shaft passes through the feed inlet and is rotatably connected to the crushing teeth. The crushing teeth are conical with their tips facing the center of the cylinder and are used to crush the material. The gears are connected to another set of crushing teeth through gear meshing.

[0010] Furthermore, the flow guiding assembly includes a flow guiding plate, a discharge pipe, and a flow guiding ring; the discharge pipe is located between the flow guiding plate and the flow guiding ring, and a valve is provided in the middle of the discharge pipe; the flow guiding plate is arc-shaped, and its curvature matches the inner wall of the lower cylinder; the flow guiding ring is located below the discharge pipe and is arranged parallel to the bottom of the lower cylinder; multiple through holes are opened on the flow guiding ring, and the through holes are evenly distributed along the circumference of the flow guiding ring.

[0030] like Figure 1 As shown, the alumina batching, stirring and dispersing device of this utility model includes a cylinder 1, a stirring component 4, a crushing component 7 and a flow guiding component 10.

[0031] The cylinder 1 is composed of an upper cylinder 2 and a lower cylinder 3 connected by a flange 15. A sealing gasket is provided at the flange 15 connection to ensure the airtightness of the cylinder 1. The upper cylinder 2 has a feed inlet on one side, and the lower cylinder 3 has a discharge outlet at the bottom. This split design facilitates disassembly and cleaning, as well as maintenance or replacement of internal components.

[0032] The stirring assembly 4 is located inside the cylinder 1 and includes a main shaft 5 and stirring blades 6. The main shaft 5 is located inside the cylinder 1 and is connected to the drive shaft 14 via a coupling. One end of the drive shaft 14 is connected to the output end of the drive motor 13 via a keyway, and the other end is fixed to the cylinder 1 via a bearing. The bearing is fixed to the cylinder 1 by a clamping nut to ensure the stability of the main shaft 5 during rotation. Multiple sets of stirring blades 6 are welded at intervals on the main shaft 5. Each set of stirring blades 6 is spirally distributed, and the spiral directions of adjacent sets of stirring blades 6 are opposite. The end of the stirring blade 6 away from the main shaft 5 maintains a certain gap with the inner wall of the cylinder 1. The surface of the stirring blade 6 is coated with a wear-resistant coating to reduce the wear of the stirring blade 6 by the material.

[0033] Example 2

[0034] Based on Example 1, in order to further improve operating efficiency, a crushing component was installed at one end of the cylinder.

[0035] The crushing component 7 is located inside the feed inlet on one side of the cylinder. The crushing component 7 includes a crushing disc 8 and crushing teeth 8, and includes crushing teeth 8, gears 9 and a drive motor.

[0036] A drive motor is located at one end of the feed inlet. One end of a transmission shaft is connected to the output end of the drive motor via a coupling, and the other end is connected to a gear 9. The transmission shaft passes through the feed inlet and rotatably connects to crushing teeth 8. The crushing teeth 8 are conical with their tips facing the center of the cylinder and are used to crush materials. The gear 9 is connected to another set of crushing teeth through gear meshing. The surface of the crushing teeth 8 is hardened to a hardness of HRC60 or higher to improve its crushing ability for high-density or easily agglomerated materials.

[0037] The crushing assembly 7 also includes a guide plate, which is set on both sides of the feed inlet and is inclined. The gear 9 is also provided with a protective cover.

[0038] The flow guiding assembly 10 is located at the bottom of the cylinder 1 and is fixedly connected to the inner wall of the cylinder 1 by bolts. The flow guiding assembly 10 includes a flow guiding plate 11, a discharge pipe and a flow guiding ring 12.

[0039] The discharge pipe is located between the guide plate 11 and the guide ring 12, and a control valve is provided in the middle of the discharge pipe. The guide plate 11 is arc-shaped, and its curvature matches the inner wall of the lower cylinder 3. The guide ring 12 is located below the discharge pipe and is set parallel to the bottom of the lower cylinder 3. Multiple through holes are opened on the guide ring 12, and the through holes are evenly distributed along the circumference of the guide ring.

[0040] A material collection trough 16 is located below the guide ring 12, and the material collection trough 16 is connected to the guide ring 12 by a snap-fit ​​connection. The bottom of the material collection trough 16 is inclined to facilitate smooth material discharge. An anti-stick layer is provided on the inner side of the guide plate 11 to reduce material adhesion.

[0041] The operation process of this utility model is as follows: The material enters the cylinder 1 through the feed port at the top of the upper cylinder 2. It first passes through the crushing component 7. The drive motor drives the crushing teeth 8 to rotate through the transmission shaft. The conical design of the crushing teeth 8 can initially crush high-density or easily agglomerated materials, preventing agglomerated materials from affecting the subsequent dispersion effect. The crushed material enters the working area of ​​the stirring component 4. Driven by the drive motor 13, the transmission shaft 14 drives the main shaft 5 to rotate, and the stirring blades 6 on the main shaft 5 rotate accordingly. The spiral distribution of the stirring blades 6 makes the material form a circulating flow in the cylinder 1, avoiding material accumulation. The spiral directions of two adjacent sets of stirring blades 6 are opposite, further enhancing the mixing effect of the material. The material gradually moves downward during the stirring process and finally reaches the guide component 10. The discharge pipe is set between the guide plate 11 and the guide ring 12, and a control valve is set in the middle. The arc design of the guide plate 11 can guide the material to be evenly distributed, and the through holes on the guide ring 12 realize the graded flow of the material, thereby improving the dispersion uniformity. After passing through the through hole of the guide ring 12, the material enters the collection trough 16. The inclined design at the bottom of the collection trough 16 facilitates the discharge of the material.

[0042] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power.
