Description

Technical Field

[0001] The utility model relates to the technical field of feeding materials for a motor high-speed disperser, in particular to a feeding structure and a high-speed disperser. Background Art

[0002] The existing high-speed disperser is a kind of mixer in a broad sense. Since the use of high-speed disperser agitator (such as disc sawtooth agitator) can form a strong element flow locally, it usually has a strong dispersing and emulsifying effect on the material, so this type of high-speed mixer is also called a disperser. In the processing of industrial raw materials, the powder mixing process is indispensable. In order to obtain uniform and refined slurry, the industry usually chooses a high-efficiency slurry system, and the rotor impeller and stator are the core components of high-efficiency slurry. Their structure is the key to determining whether the slurry can be mixed evenly.

[0003] At present, the industry usually uses a high-efficiency disperser with horizontal feeding and discharging, which is inlet and outlet from the top or inlet and outlet from the bottom. The powder is first mixed and infiltrated in the powder-liquid mixing chamber through the feeding port, and then enters the dispersion chamber. The high-speed rotation of the rotor in the dispersion chamber is used to disperse and emulsify the finished slurry. In this feeding method, the powder is easy to adhere to the feeding port and the inner wall of the pipe, which affects the powder feeding efficiency.

[0004] Therefore, how to improve the powder feeding efficiency of a high-speed disperser is a technical problem that those skilled in the art currently need to solve. Utility Model Content

[0027] Hollow shaft 100, solid shaft 101, powder inlet 102, blades 103, dispersion chamber 200, feed port 300, machine body 400, seal 500, drive motor 600, main drive pulley 601, belt 602, driven pulley 603, and discharge port 700. DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making novel work are within the scope of protection of the utility model.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "top surface", "bottom surface" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the positions or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limitations of the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0030] The feeding structure disclosed in the utility model is arranged inside the body 400 of the high-speed disperser, and includes a hollow shaft 100, a solid shaft 101, a connecting piece and a dispersion chamber 200, wherein a powder inlet 102 is arranged at the first end of the hollow shaft 100, and the powder inlet 102 is used to input powder, and the connecting piece is used to connect the second end of the hollow shaft 100 and the first end of the solid shaft 101, and through holes are distributed along the vertical direction between the second end of the hollow shaft 100 and the first end of the solid shaft 101, and the through holes penetrate the cavity of the hollow shaft 100 and the interior of the body 400, and the second end of the solid shaft 101 is connected to the dispersion chamber 200, and is used to drive the dispersion chamber 200 to rotate, and the dispersion chamber 200 is used to disperse and emulsify powder. Specifically, the solid shaft 101 is arranged below the hollow shaft 100, and the second end of the hollow shaft 100 is of a conical design to increase the connection area with the hollow shaft 100 and improve the connection stability between the solid shaft 101 and the hollow shaft 100. Specifically, the first end of the solid shaft 101 is of a conical design so that the powder is evenly dispersed when falling and does not stay on the end surface of the solid shaft 101, thereby improving the powder feeding efficiency of the high-speed disperser. When in use, the powder enters the hollow shaft 100 from the powder inlet 102 at the first end of the hollow shaft 100, enters the space formed by the solid shaft 101 and the inner wall of the body 400 after passing through the through hole, and enters the dispersion cavity 200, and is dispersed and emulsified inside the dispersion cavity 200. Because the powder enters the dispersion chamber 200 directly from the hollow shaft 100, the powder enters the dispersion chamber 200 vertically, thereby avoiding the powder adhering to the inner wall of the hollow shaft 100, thereby improving the powder feeding efficiency of the high-speed disperser. When the dispersion chamber 200 is working, the hollow shaft 100 is in a rotating state, and the powder evenly enters the space formed by the solid shaft 101 and the inner wall of the body 400 through the through hole, thereby further improving the powder feeding efficiency of the high-speed disperser.

[0031] Furthermore, the outer periphery of the solid shaft 101 is also connected to blades 103. When the solid shaft 101 rotates, the blades 103 rotate together, and the powder in the space formed by the solid shaft 101 and the inner wall of the body 400 is evenly transported to the dispersion chamber 200, thereby improving the powder feeding efficiency of the high-speed disperser.

[0032] In some embodiments of the utility model, the connecting member is a rib plate, the inner periphery of the rib plate is connected to the solid shaft 101, and the outer periphery of the rib plate is connected to the hollow shaft 100. Specifically, because the rib plate includes a plurality of reinforcing ribs, there will be a through hole between the two reinforcing ribs, that is, the above-mentioned through hole is formed. When in use, the rib plate is fixedly connected to the solid shaft 101 and the hollow shaft 100, and a plurality of through holes are formed between the connection between the solid shaft 101 and the hollow shaft 100. When the powder falls, it can enter the space formed by the inner wall of the solid shaft 101 and the body 400 from the through hole, and finally directly enter the dispersion chamber 200 below. Because the dispersion chamber 200 is in a rotating state during operation, the powder can fall evenly through the plurality of through holes, thereby avoiding the accumulation of powder and improving the powder feeding efficiency of the high-speed disperser.

[0033] In some other embodiments of the utility model, the connecting member is a connecting plate, the number of the connecting plates is two or more, the inner side of the connecting plate is connected to the solid shaft 101, and the outer side of the connecting plate is connected to the hollow shaft 100. Specifically, the connecting plate, the solid shaft 101 and the hollow shaft 100 are fixedly connected, including but not limited to welding. When in use, two or more connecting plates can be arranged at intervals between the connection between the solid shaft 101 and the hollow shaft 100, and the above-mentioned through holes will be formed between two adjacent connecting plates so that the powder can fall smoothly. Such an arrangement allows the operator to change the number of connecting plates according to the needs of use, thereby adjusting the size of the through holes to meet various production needs.

[0034] In order to optimize the above technical solution, the feeding structure also includes a powder tube, which is sleeved inside the hollow shaft 100, and one end of the powder tube away from the dispersion chamber 200 is a powder inlet 102. Specifically, the outer wall of the powder tube can fit the inner wall of the hollow shaft 100, and the powder tube is clamped to the inside of the hollow shaft 100 to achieve feeding. The outer wall of the powder tube may not fit the inner wall of the hollow shaft 100, and the bottom of the powder tube is clamped to the second end of the hollow shaft 100, which can also achieve feeding. One end of the powder tube away from the dispersion chamber 200 extends out of the first end of the hollow shaft 100, so that the powder inlet 102 can be connected to the device for feeding. Specifically, the powder tube includes but is not limited to shapes such as cylinders and cuboids. By arranging the powder tube, the contact between the powder and the hollow shaft 100 can be reduced, thereby further preventing the powder from adhering to the inner wall of the hollow shaft 100. At the same time, when powder adheres to the inner wall of the powder tube, the operator can replace and flush the powder tube separately to facilitate maintenance of the feeding structure.

[0035] In order to optimize the above technical solution, the feeding structure also includes a feeding port 300, which is connected to the bottom of the dispersion chamber 200 and is used to input slurry into the dispersion chamber 200. When in use, the powder enters the dispersion chamber 200 from the powder inlet 102 from top to bottom, and the slurry enters the dispersion chamber 200 from the feeding port 300 from bottom to top. The powder and the slurry are mixed inside the dispersion chamber 200, and then dispersed and refined to form a material. Such an arrangement allows the powder and the slurry to be fully mixed, thereby improving the dispersion and emulsification efficiency of the dispersion chamber 200.

[0036] like Figure 1 As shown, the high-speed disperser disclosed in the utility model comprises a machine body 400, a driving device and a feeding structure as described above, wherein the feeding structure is arranged inside the machine body 400, and the driving device is connected to the hollow shaft 100 of the feeding structure, and is used to drive the hollow shaft 100 to rotate. When in use, the driving device drives the hollow shaft 100 to rotate, and the powder in the hollow shaft 100 enters the space formed by the solid shaft 101 and the inner wall of the machine body 400, and at the same time, the hollow shaft 100 drives the solid shaft 101 to rotate, and the powder in the space formed by the solid shaft 101 and the inner wall of the machine body 400 enters the dispersion cavity 200, thereby completing the feeding process of the high-speed disperser. It should be noted that, in the prior art, the existing high-speed disperser is usually arranged with a separate feed pipe and a transmission shaft, so the utility model makes the transmission shaft and the feed pipe of the existing high-speed disperser integrated, that is, the feed pipe of the existing high-speed disperser is eliminated, and the feeding is achieved by the cooperation of the hollow shaft 100 and the solid shaft 101, which simplifies the feeding structure of the high-speed disperser and improves the powder feeding efficiency of the high-speed disperser.

[0037] In order to optimize the above technical solution, the high-speed disperser further includes a seal 500, which is connected to the inner wall of the body 400. Specifically, the seal 500 is arranged above the dispersion cavity 200, and is clamped to the outer periphery of the solid shaft 101 or the hollow shaft 100, and is used to form a seal for the portion below the seal 500 to prevent the powder from ascending, thereby protecting the high-speed disperser and increasing its service life.

[0038] In order to optimize the above technical solution, the driving device includes a driving motor 600, a main driving pulley 601, a belt 602 and a passive pulley 603, the driving motor 600 is connected to the main driving pulley 601, the main driving pulley 601 and the passive pulley 603 are respectively arranged at the two ends of the belt 602, and the passive pulley 603 is connected to the first end of the hollow shaft 100, and is used to drive the hollow shaft 100 to rotate. Specifically, the belt transmission has good flexibility and elasticity, can absorb and distribute the impact force generated during the transmission process, and make the transmission smooth and noiseless. When in use, the driving motor 600 drives the main driving pulley 601 to rotate, and under the transmission action of the belt 602, the main driving pulley 601 drives the passive pulley 603 to rotate, the passive pulley 603 drives the hollow shaft 100 to rotate, and the hollow shaft 100 drives the dispersion cavity 200 to rotate, thereby achieving the mixing, dispersion and refinement of the powder and the slurry.

[0039] In order to optimize the above technical solution, the high-speed disperser also includes a discharge port 700, which is connected to the dispersion cavity 200 of the feed structure for discharging materials. When in use, the powder and slurry are mixed, dispersed and refined inside the dispersion cavity 200 to form materials. After the materials are refined inside the dispersion cavity 200, they leave the high-speed disperser from the discharge port 700.
