Technical Field

[0001] This utility model relates to the field of mixing equipment, and in particular to a raw material uniform mixing device with a mixing chamber. Background Technology

[0002] In many industrial fields such as chemical engineering, energy, and materials preparation, uniform mixing of materials is a key step in ensuring product quality, optimizing reaction efficiency, and improving the stability of the production process. In particular, for processes involving chemical reactions, such as methanol to hydrogen production, the initial uniformity of raw material mixing is directly related to the utilization efficiency of the catalyst, the reaction rate, and the final yield and purity of hydrogen.

[0003] Most commonly used mixing devices in the present technology adopt a single stirring structure, such as setting stirring blades in the mixing chamber and driving the material to stir through a motor. However, such devices often have mixing dead zones, especially for materials with high viscosity or special rheological properties. Materials near the inner wall and bottom of the container are difficult to be effectively stirred, resulting in uneven mixing. In addition, traditional mixing equipment usually only performs overall mixing at the end, lacking full-process, multi-stage mixing planning from material feeding to discharge, resulting in low mixing efficiency and high energy consumption.

A stirring disc is fixedly connected to the outer wall of the connecting rod.

[0007] As a further description of the above technical solution: The number of gears two is set in multiple sets, and the multiple sets of gears two are arranged in a rotating array with the center line of the rotating rod as the rotation axis.

[0008] As a further description of the above technical solution: An insulation sleeve is fixedly connected to the outer wall of the mixing tube, and a heating tube is fixedly connected to the inner wall of the insulation sleeve. The heating tube is spiral-shaped.

[0019] Reference Figure 2 and Figure 3 The mixing mechanism also includes a stirring assembly 6, which includes a stirring rod 61 for stirring the material inside the shell 1. The stirring rod 61 is fixedly connected to the outer wall of the rotating rod 42. A support seat 62 for supporting other components is fixedly connected to the inner wall of the shell 1. A gear 63 is fixedly connected to the end of the support seat 62 away from the shell 1. The gear 63 is a gear disk. When the gear 64 rotates on the gear 63, it drives the connecting rod 65 to rotate. The gear 63 meshes with the gear 64. A connecting rod 65 for connecting the stirring disk 67 to rotate is fixedly connected to the inner wall of the gear 64. A sealing frame 66 for the rotating rod 42 to drive the gear 64 is rotatably connected to the outer wall of the connecting rod 65. The sealing frame 66 is used for... Gear 63 and gear 64 are enclosed. A stirring disc 67 for stirring materials is fixedly connected to the outer wall of the connecting rod 65. Multiple sets of gear 64 are arranged in a rotating array around the center line of the rotating rod 42, driving multiple sets of stirring discs 67 to rotate and stir. The stirring rod 61 is arc-shaped and multiple sets of stirring rods are arranged in a rotating array around the center line of the rotating rod 42, continuously stirring the material after rotation. A sealing frame 66 is fixedly connected to the inner wall of the rotating rod 42. The sealing frame 66 drives the connecting rod 65 to rotate along the axis of the rotating rod 42, and the connecting rod 65 is rotatably connected to the inner wall of the sealing frame 66.

[0020] Reference Figure 2 , Figure 3 and Figure 4An insulation sleeve 7 is fixedly connected to the outer wall of the mixing tube 2 to keep the mixed materials warm. A heating tube 8 is fixedly connected to the inner wall of the insulation sleeve 7. The heating tube 8 is spirally wound around the outer wall of the mixing tube 2. The rotating rod 42 is rotatably connected to the inner wall of the support base 62 and is supported and fixed by the support base 62. The flow divider 43 is fixedly connected to the inner wall of the mixing tube 2 and is supported by the mixing tube 2. The baffle 44 is fixedly connected to the inner wall of the mixing tube 2. The flow divider 43 is spirally shaped. The baffle 44 is arc-shaped and made of elastic material. When the stirring plate 45 rotates, it will squeeze the baffle 44 to extend and push the material near the edge. Multiple sets of baffles 44 are arranged in an array rotating around the center line of the rotating rod 42.

[0021] Working Principle: During operation, the motor 41 is started, and its output shaft drives the rotating rod 42 to rotate. The material enters the mixing tube 2 through the feeding mechanism 3. The rotating rod 42 first drives the agitator 45 on its outer wall to rotate, pushing the material to the left and initially mixing it. During this process, the spiral diverting plate 43 fixed to the inner wall of the mixing tube 2 divides and guides the material flow, changing its flow path and thus strengthening the mixing. Simultaneously, the rotating agitator 45 periodically squeezes or sweeps past the arc-shaped baffle 44 made of elastic material. The baffle 44 generates elastic deformation and vibration, disturbing the material in the edge area near the inner wall of the mixing tube 2, effectively preventing material deposition on the tube wall and ensuring the uniformity of the initial mixing. The initially mixed material then enters the main mixing chamber inside the shell 1. Inside the shell 1, the rotating rod 42 drives multiple sets of arc-shaped agitators 61 to rotate synchronously, performing large-scale macro-stirring of the material. At the same time, the material is further stirred by the sealing frame 66. The connecting rod 65 and gear 64, fixed on the rotating rod 42, revolve accordingly. Since gear 64 meshes with gear 63 fixed on the support base 62, the revolving motion forces gear 64 to rotate around its own axis, thereby driving the connecting rod 65 and the stirring disc 67 on it to rotate simultaneously. This combined motion of revolving and rotating, achieved by the gear transmission system, forms a complex and efficient multi-dimensional shearing and convection field within the shell 1. Multiple stirring discs 67 operate in this manner, enabling thorough microscopic dispersion and shear mixing of the materials, greatly improving the uniformity of the final product. In addition, during the entire mixing process, the spiral heating tube 8, installed in the insulation sleeve 7, can be activated according to the material characteristics to heat or keep warm the material flowing through the mixing tube 2, providing a suitable temperature environment for the mixing process and promoting physical mixing or subsequent chemical reactions. Finally, the remaining material is discharged through the discharge pipe 5 at the bottom of the shell 1, completing the entire mixing process.
