Description

Technical Field

[0001] This application relates to the field of mixing technology, and more specifically, to a mineral raw material mixing device. Background Technology

[0002] In the metal processing industries such as steel smelting and casting, the mixing of silicon-calcium ore raw materials is a key step in ensuring product quality and production efficiency.

[0003] Chinese Patent Publication No. CN220003805U discloses a high-efficiency mixing device for mineral raw materials, including a first conveyor belt, a second conveyor belt, and a mixing component. The first conveyor belt is used to transport the mineral raw materials after initial mixing; the second conveyor belt is disposed below the first conveyor belt; the mixing component is disposed between the first and second conveyor belts, and the mineral raw materials on the first conveyor belt undergo secondary mixing through the mixing component before entering the second conveyor belt. By setting up the mixing component to perform secondary stirring of the raw materials, the mixing quality of the mixed ore can be effectively improved, the content deviation of major elements such as silicon and calcium can be reduced, and favorable raw material conditions can be created for effective control of alkalinity in the subsequent sintering process.

[0004] The aforementioned high-efficiency mineral raw material mixing device includes an impact unit and a collection unit. The impact unit includes a receiving plate with a trapezoidal groove at one end near the first conveyor belt. The power output end of the drive motor is connected to the receiving plate. However, during the operation of the high-efficiency mineral raw material mixing device, when the mineral raw material falls from the first conveyor belt, it generates an impact load on the trapezoidal groove of the receiving plate. This load is entirely transmitted to the motor shaft through the connection between the receiving plate and the output shaft of the drive motor, causing stress concentration and making it prone to overload. This can lead to overheating and burnout of the drive motor, seriously affecting the reliability and service life of the equipment. Summary of the Invention

[0005] The purpose of this application is to provide a mineral raw material mixing device that can solve the technical problems mentioned in the background art.

[0006] This application provides a mineral raw material mixing device, including a shell, an inlet at the upper end of one side of the shell, an outlet at the bottom of the shell, and a mixing component inside the shell for mixing the materials entering the shell. The mixing component includes a receiving plate and a pressure dividing cylinder. One end of the pressure dividing cylinder is fixed to the inner wall of the shell on the side opposite to the inlet. One side of the receiving plate is rotatably connected to the pressure dividing cylinder. A drive component for driving the receiving plate to rotate is provided on the outer side of the shell.

[0007] Furthermore, the receiving plate has a trapezoidal groove on the side near the feed inlet, and an annular groove adapted to the pressure dividing cylinder on the side away from the feed inlet. The end of the pressure dividing cylinder near the receiving plate is rotatably connected to the receiving plate through the annular groove.

[0008] Furthermore, the inner wall of the annular groove is movably embedded with multiple balls at equal intervals in an annular shape, and the pressure dividing cylinder is provided with an annular limiting groove adapted to the balls, and the balls are slidably connected to the annular limiting groove.

[0009] Furthermore, the drive assembly includes a drive motor, a rotating shaft, and a mounting plate. The drive motor is fixed to the housing via the mounting plate. The rotating shaft is rotatably disposed inside the housing. One end of the rotating shaft is fixedly connected to the receiving plate, and the other end of the rotating shaft away from the receiving plate extends outside the housing and is connected to the output shaft of the drive motor.

[0010] Furthermore, a reinforcing rib is provided at the connection between the rotating shaft and the receiving plate, and a bearing is provided at the connection between the rotating shaft and the housing.

[0011] Furthermore, a baffle plate and a guide plate are fixed inside the housing. Both the baffle plate and the guide plate are located below the feed inlet. The guide plate is used to guide the material falling from the baffle plate to the receiving plate.

[0012] Furthermore, the receiving surfaces of the receiving plate, the baffle plate, and the guide plate are all provided with a wear-resistant layer.

[0013] The beneficial effects of this utility model are:

[0014] The mixing component provided by this utility model includes a receiving plate and a pressure dividing cylinder. One end of the pressure dividing cylinder is fixed on the inner wall of the housing opposite to the feed inlet. One side of the receiving plate is rotatably connected to the pressure dividing cylinder. The setting of the pressure dividing cylinder can transfer the impact load borne by the receiving plate to the housing, avoiding the load from acting directly on the drive component, reducing the overload risk of the drive component.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Specific implementation examples:

[0028] like Figure 1-3 As shown, this application provides a mineral raw material mixing device, including a shell 1. A feed inlet 11 is provided at the upper end of one side of the shell 1, and a discharge outlet 12 is provided at the bottom of the shell 1. A mixing component 2 for mixing materials entering the shell 1 is provided inside the shell 1. The mixing component 2 includes a receiving plate 21 and a pressure dividing cylinder 22. One end of the pressure dividing cylinder 22 is fixed to the inner wall of the shell 1 on the side opposite to the feed inlet 11. One side of the receiving plate 21 is rotatably connected to the pressure dividing cylinder 22. A drive component 3 for driving the receiving plate 21 to rotate is provided on the outer side of the shell 1. In use, the initially mixed mineral raw material is conveyed by a belt conveyor and enters the shell 1 through the feed inlet 11. During the fall of the mineral raw material, it impacts the receiving plate 21, and simultaneously, the drive component 3 drives the receiving plate 21. As the plate rotates, the raw materials form vortices at the upper and lower adjacent interfaces of the receiving plate 21. When the vortices are generated, they sweep in and bring in various raw materials from the surrounding area, which can perform secondary stirring on the raw materials. This achieves the purpose of further mixing of the initially mixed raw materials. The further mixed raw materials flow out through the discharge port 12, fall into another belt conveyor and are transported to the required position. The pressure-distributing cylinder 22 can transfer the impact load borne by the receiving plate 21 to the housing 1, avoiding the load from acting directly on the drive component 3, reducing the overload risk of the drive component 3. Compared with the prior art, it can reduce the stress concentration of the motor shaft of the drive motor 31, avoid overheating and burning of the drive motor 31 due to overload, and improve the reliability and service life of the equipment.

[0029] like Figure 2 and Figure 3As shown, the receiving plate 21 has a trapezoidal groove 211 on the side near the feed inlet 11, and an annular groove 212 adapted to the pressure dividing cylinder 22 on the side away from the feed inlet 11. The end of the pressure dividing cylinder 22 near the receiving plate 21 is rotatably connected to the receiving plate 21 through the annular groove 212. When the raw material impacts the receiving plate 21, the inclined surface of the trapezoidal groove 211 will divert the material to both sides, forming a radial diffusion effect. During the rotation of the receiving plate 21, the diffused material will form a vortex on the receiving plate 21. When the vortex is generated, it will sweep and bring in various raw materials around it, which can perform secondary stirring on the raw material. The setting of the annular groove 212 ensures the continuous rotation of the receiving plate 21.

[0030] like Figure 2 and Figure 3 As shown, the inner sidewall of the annular groove 212 is movably embedded with multiple balls 4 at equal intervals in an annular shape. The pressure dividing cylinder 22 is provided with an annular limiting groove 221 that matches the balls 4. The balls 4 are slidably connected to the annular limiting groove 221. When the drive assembly 3 drives the receiving plate 21 to rotate, the balls 4 on the inner side of the annular groove 212 roll along the annular limiting groove 221 of the pressure dividing cylinder 22, effectively reducing the frictional resistance between the receiving plate 21 and the pressure dividing cylinder 22 and reducing energy consumption.

[0031] like Figure 1-3 As shown, the drive assembly 3 includes a drive motor 31, a rotating shaft 32, and a mounting plate 33. The drive motor 31 is fixed to the housing 1 via the mounting plate 33. The rotating shaft 32 is rotatably disposed inside the housing 1. One end of the rotating shaft 32 is fixedly connected to the receiving plate 21, and the other end of the rotating shaft 32 away from the receiving plate 21 extends to the outside of the housing 1 and is connected to the output shaft of the drive motor 31. Specifically, the mounting plate 33 is fixed to the housing 1, and the drive motor 31 is fixed to the mounting plate 33. The drive motor 31 drives the rotating shaft 32 to rotate, thereby driving the receiving plate 21 to rotate. The rotating shaft 32 and the pressure-distributing cylinder 22 form a double-support structure. The pressure-distributing cylinder 22 disperses part of the material impact load to the housing 1, reducing single-point stress and reducing stress concentration on the motor shaft of the drive motor 31.

[0032] like Figure 2 As shown, a reinforcing rib 5 is provided at the connection between the rotating shaft 32 and the receiving plate 21, and a bearing 6 is provided at the connection between the rotating shaft 32 and the housing 1. The reinforcing rib 5 strengthens the structure at the connection between the rotating shaft 32 and the receiving plate 21 and enhances the stability of the structure, while the bearing 6 reduces the frictional resistance at the connection between the rotating shaft 32 and the housing 1 and reduces energy consumption.

[0033] like Figure 2As shown, a baffle plate 7 and a guide plate 8 are fixed inside the housing 1. Both the baffle plate 7 and the guide plate 8 are located below the feed inlet 11. The guide plate 8 is used to guide the material falling from the baffle plate 7 to the receiving plate 21. When the material falls from the feed inlet 11, it first impacts the baffle plate 7. The baffle plate 7 changes the direction of the material's movement, causing it to slide down the surface of the baffle plate 7. After being guided by the guide plate 8, the sliding material falls into the trapezoidal groove 211 of the receiving plate 21 at a specific angle, ensuring that the material is in full contact with the rotating receiving plate 21. During the collision process, some of the material is broken by the baffle plate 7, which can further improve the mixing effect.

[0034] like Figure 2 As shown, the receiving surfaces of the receiving plate 21, the baffle plate 7, and the guide plate 8 are all provided with wear-resistant layers. The wear-resistant layers can reduce the wear of the receiving plate 21, the baffle plate 7, and the guide plate 8, and extend their service life.

[0035] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
