Description

Technical Field

[0001] The utility model relates to the field of mixers, and particularly relates to a raw material mixing and stirring device. Background Art

[0002] A mixer is a material mixing device that realizes the mixing process of multiple different materials by means of rotary stirring. The mixer can be used to mix and process different types of materials.

[0003] When using a traditional mixer to mix and stir granular raw materials, under the action of centrifugal force, the raw materials will adhere to the surface of the stirring arms inside the mixer and the inner wall of the mixer, and will continuously accumulate, making it difficult to fully stir and mix the raw materials, which will affect the uniformity of raw material mixing. At the same time, it will increase the stirring load and the energy consumption of the mixer. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a raw material mixing and stirring device that can completely mix the product to be stirred in the shortest possible time according to the stirring operation to obtain the highest possible stirring quality.

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] A raw material mixing and stirring device of the utility model includes a stirring kettle and a fixing frame. The stirring kettle is fixed on the fixing frame. There is a discharge port at the bottom of the stirring kettle. A first driving motor is arranged on the fixing frame. The output end of the first driving motor is connected with a central shaft. The top end of the central shaft is fixedly connected with a speed reducer. A second driving motor is also arranged on the fixing frame. The output end of the second driving motor is connected with a hollow shaft. The upper end of the hollow shaft extends into the stirring kettle. A mixer rotor is coaxially arranged with the hollow shaft. The mixer rotor is circumferentially fixedly connected with a bracket. Fixed blades are arranged at the lower part of the bracket. One side of the bracket is rotatably connected with a stirring rod. The top of the stirring rod is rotatably connected with the speed reducer.

[0007] As a preferred technical solution of the utility model, the central shaft and the hollow shaft rotate in opposite directions.

[0008] As a preferred technical solution of the utility model, a transmission gear is arranged at the output end of the first driving motor. The hollow shaft is connected with the first driving motor through the transmission gear.

[0009] As a preferred technical solution of the utility model, the mixer rotor is driven by the hollow shaft.

[0010] As a preferred technical solution of the utility model, a stirring blade is fixedly connected to the lower end of the stirring rod.

[0011] As a preferred technical solution of the present utility model, the central shaft is arranged inside the hollow shaft.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Through the combined design of the mixer rotor and the fixed blades, as well as the combination of the stirring rod and the stirring blades, the present utility model can achieve various combination modes of the stirring blades and the fixed blades. By turning the raw materials upward or downward with the stirring blades and changing the stirring and mixing position of the stirring rod, the raw materials attached to the surface of the mixer rotor and the inner wall of the mixing device can be scraped off, which is beneficial to fully mixing and stirring the raw materials in the fixed frame to ensure the stirring effect.

[0014] 2. The present utility model can independently adjust the rotation speeds of the mixer rotor and the stirring rod. The rotation speed of the fixed blades is controlled by the mixer rotor, and the rotation speed of the stirring blades is controlled by the stirring rod, forming a double agitator system.

[0023] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0024] Among them, the same reference numerals in the drawings all refer to the same components.

[0025] As Figure 1-6 shown, the present utility model provides a raw material mixing and stirring device. Through the combined design of the mixer rotor 15 and the fixed blades 14, and the combined design of the stirring rod 10 and the stirring blades 13, the rotation speeds of the mixer rotor 15 and the stirring rod 10 can be independently adjusted, and the adjustment and matching of multiple rotation speeds of the stirring blades 13 and the fixed blades 14 can be realized, forming a double stirrer system, which is suitable for the stirring and mixing of raw materials with different densities and volumes.

[0026] The usage method of the present utility model is as follows:

[0027] 1. As Figure 1-6 shown, the present utility model includes a stirring kettle 1 and a fixed frame 2. The stirring kettle 1 is fixed above the fixed frame 2. The bottom of the stirring kettle 1 is provided with a discharge port 9. A first driving motor 3 is provided on the fixed frame 2. Preferably, the bottom of the first driving motor 3 is fixedly connected to the fixed frame 2 by bolts; the output end of the first driving motor 3 is connected to a central shaft 8. Preferably, a helical gear connection is adopted between the first driving motor 3 and the central shaft 8. A gear disc is provided at the bottom of the central shaft 8 and is connected to the first driving motor 3. The top end of the central shaft 8 is fixedly connected to a speed reducer 11. Preferably, a gear is fixedly connected to the top end of the central shaft 8, and is connected to the gear in the speed reducer 11 through the gear. When the first driving motor 3 rotates, the gear in the speed reducer 11 can be driven through the central shaft 8;

[0028] 2. The fixing frame 2 is also provided with a second driving motor 6. Preferably, the base of the second driving motor 6 is fixedly connected to the side wall of the fixing frame 2 by bolts. The output end of the second driving motor 6 is connected with a hollow shaft 7 through a belt. The upper end of the hollow shaft 7 extends into the stirring kettle 1. A stirring machine rotor 15 is coaxially arranged at the upper end of the hollow shaft 7. A support 12 is fixedly connected to the stirring machine rotor 15 in the circumferential direction. Multiple groups of fixed blades 14 are arranged at the lower part of the support 12. Preferably, 4 groups are arranged in this embodiment and are connected to the support 12 by welding. By adjusting the rotation speed of the second driving motor 6 to control the rotation speed of the stirring machine rotor 15, the rotation speed of the fixed blades 14 can be controlled, so that the rotation speed of the fixed blades 14 is controllable, and thus the stirring effect can be adjusted. One side of the support 12 is rotatably connected with a stirring rod 10. Preferably, a bearing connection is adopted between the main shaft of the stirring rod 10 and the support 12. The top of the stirring rod 10 is rotatably connected with a speed reducer 11. Preferably, a gear is arranged at the top of the stirring rod 10 and is connected with the gear in the speed reducer 11. When the first driving motor 3 drives the gear in the speed reducer 11 to rotate, the rotation speed of the stirring rod 10 can be indirectly controlled, so that the rotation speed of the stirring rod 10 is controllable, and thus the stirring effect can be adjusted.

[0029] 3. As Figure 1-6 shown, the rotatable stirring rod 10 and the stirring machine rotor 15 are respectively driven by the first driving motor 3 and the second driving motor 6, and the rotation speeds are continuously adjustable and can be independently set. The rotation speed of the fixed blades 14 is controlled by the stirring machine rotor 15, and the rotation speed of the stirring blades 13 is controlled by the stirring rod 10. The two types of blades are mechanically independent of each other, forming a double agitator system. For raw materials with different densities and volumes, the stirring speed combination can be flexibly adjusted to improve the stirring and mixing effect, and at the same time, the resistance of the rotational stirring can be reduced.

[0030] Furthermore, the central shaft 8 rotates in the opposite direction to the hollow shaft 7, and the stirring rod 10 and the stirring machine rotor 15 controlled thereby rotate in the opposite direction, indirectly controlling the fixed blades 14 and the stirring blades 13 to rotate in the opposite direction, improving the mixing efficiency of the raw materials.

[0031] Furthermore, a transmission gear 4 is arranged at the output end of the first driving motor 3. The bottom end of the hollow shaft 7 is connected to the first driving motor 3 through the transmission gear 4. Preferably, a pin hole is arranged at the bottom end of the hollow shaft 7 and is fixedly connected to the transmission gear 4 through the pin hole.

[0032] Furthermore, the stirring machine rotor 15 is driven by the hollow shaft 7. Preferably, the upper end of the stirring machine rotor 15 is fixedly connected to the top of the hollow shaft 7 by bolts. By driving the hollow shaft 7, the rotation speed of the stirring machine rotor 15 can be changed.

[0033] Furthermore, as Figure 5-6, a stirring blade 13 is fixedly connected to the lower end of the stirring rod 10. When the first driving motor 3 drives the stirring rod 10 to rotate, the rotation of the stirring blade 13 can be controlled. Preferably, the stirring blades 13 are symmetrically arranged along the central axis of the stirring rod 10, and the stirring blades 13 have a certain inclination angle with the stirring rod 10. During the rotation process, the raw materials can be driven to move up and down, improving the stirring effect.

[0034] Further, the central shaft 8 is arranged inside the hollow shaft 7. Preferably, the central shaft 8 and the hollow shaft 7 are connected by bearings, and the two can be independently driven by motors. The outer circle of the hollow shaft 7 is fixedly connected to the fixing frame 2 through a bearing.
