Description

Technical Field

[0001] This invention belongs to the technical field of material mixing and stirring equipment, and more specifically, it relates to a horizontal mixer with dual-shaft stirring and cylinder tilting functions. Background Technology

[0002] Currently, the main equipment used for mixing high-viscosity materials includes traditional horizontal ribbon mixers, planetary mixers, and fixed cylindrical twin-shaft mixers. Traditional horizontal ribbon mixers are typically single-shaft designs, which can easily create a "stagnant zone" for high-viscosity materials, resulting in uneven mixing and insufficient shear force. While planetary mixers offer good mixing performance, their complex structure, high cost, and difficult maintenance make them unsuitable for large-scale equipment. Fixed cylindrical twin-shaft mixers, although using two shafts, suffer from difficult discharge; high-viscosity materials flow slowly from the bottom discharge gate, leaving significant residue that requires manual cleaning, leading to low efficiency and waste. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a horizontal mixer with dual-shaft stirring and cylinder tilting functions, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a horizontal mixer with dual-shaft stirring and cylinder tilting functions, comprising a cylinder, a frame base, and a stirring system. The cylinder surface is provided with an upper feed inlet and a side discharge outlet, and also includes a tilting discharge system. The stirring system includes a low-speed stirring unit and a high-speed stirring unit. The low-speed stirring unit includes a low-speed main shaft arranged along the axial center of the cylinder, a low-speed stirring blade fixed to the low-speed main shaft, and a bottom drive mechanism for driving the low-speed main shaft. The low-speed stirring blade is an ascending spiral structure closely attached to the inner wall of the cylinder. The high-speed stirring unit... The system includes a high-speed main shaft parallel to the low-speed main shaft but located on the side of the cylinder, not at the center; a high-speed stirring blade fixed to the high-speed main shaft; and a side drive mechanism for driving the high-speed main shaft. The high-speed stirring blade is a blade assembly consisting of multiple layers of blades arranged axially, with the blade assembly extending radially into the helical gap of the low-speed stirring blade. The tilting discharge system includes a bottom support fixed to the frame base and a tilting drive device. The bottom of the cylinder is hinged to the bottom support. One end of the tilting drive device is hinged to the frame base, and the other end is hinged to the cylinder, for driving the cylinder to rotate and tilt around the hinge axis.

[0005] As an optional embodiment of the present invention, the tilting drive device is a hydraulic cylinder or an electric lead screw.

[0006] As an optional embodiment of the present invention, the bottom drive mechanism includes a bottom drive motor and a bottom reducer; the side drive mechanism includes a side drive motor and a side reducer.

[0007] As an optional embodiment of the present invention, the multi-layered blades of the high-speed stirring impeller are arranged in an alternating manner in the circumferential direction.

[0008] As an optional embodiment of the present invention, the tilting drive device can drive the cylinder to tilt from a horizontal position to a vertical position.

[0009] This invention provides a horizontal mixer with dual-shaft stirring and cylinder tilting functions, which has the following beneficial effects: 1. Excellent mixing effect with no dead angles: By combining the forced circulation of low-speed propellers with the high shear dispersion of high-speed multi-layer blades, the complementary motion trajectories achieve mixing without dead angles in three-dimensional space, resulting in high material homogeneity.

[0010] 2. Fast and thorough discharge: The entire cylinder is tilted for discharge. By utilizing the material's own weight and tilt angle, along with the assistance of a low-speed paddle, high-viscosity materials can be discharged smoothly like a fluid, leaving almost no residue. This improves efficiency and reduces material waste.

[0011] 3. Reasonable structure and convenient maintenance: The low-speed and high-speed drive systems are set independently, with a short transmission path, high efficiency, and can be inspected and maintained independently, which improves the stability and maintainability of the equipment.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0017] Please see Figures 1 to 3 The present invention provides a technical solution: a horizontal mixer with dual-shaft stirring and cylinder 1 tilting function, including cylinder 1, frame base 2, stirring system 3 and tilting discharge system 4.

[0018] The cylinder 1 is horizontally positioned, with an upper feed inlet 11 at the top and a side discharge outlet 12 on the side. The stirring system 3 includes a low-speed stirring unit 31 and a high-speed stirring unit 32.

[0019] The low-speed stirring unit 31 includes a low-speed main shaft 311, a low-speed stirring paddle 312, a bottom drive motor 3131, and a bottom reducer 3132. The low-speed main shaft 311 is arranged along the axial centerline of the cylinder 1 and is supported at both ends of the cylinder 1 by bearings. The low-speed stirring paddle 312 is fixedly installed on the low-speed main shaft 311, and its blades are a rising spiral structure that fits tightly against the inner wall of the cylinder 1, used to lift the bottom material upward along the cylinder wall and scrape the cylinder wall. The bottom drive motor 3131 is connected to one end of the low-speed main shaft 311 through the bottom reducer 3132.

[0020] The high-speed stirring unit 32 includes a high-speed main shaft 321, a high-speed stirring paddle 322, a side drive motor 3231, and a side reducer 3232. The high-speed main shaft 321 is arranged parallel to the low-speed main shaft 311, but located on the side of the cylinder 1 at a non-central position. The high-speed stirring paddle 322 is fixedly mounted on the high-speed main shaft 321 and is a blade assembly consisting of multiple layers of blades arranged axially, covering the entire length of the cylinder 1. The multiple layers of blades extend radially into the helical gaps of the low-speed stirring paddle 312, and their movement trajectories are interlaced and complementary. The side drive motor 3231 is connected to one end of the high-speed main shaft 321 via the side reducer 3232.

[0021] The tilting discharge system 4 includes a bottom support 41 and a tilting drive device 42. The bottom support 41 is fixed to the frame base and hinged to the bottom of the cylinder 1 via a hinge shaft. One end of the tilting drive device 42 is hinged to the frame, and the other end is hinged to the cylinder 1, for driving the cylinder 1 to rotate around the hinge shaft, tilting the cylinder 1 from a horizontal mixing state to a vertical discharge state. The tilting drive device 42 is a hydraulic cylinder or an electric screw. The helix angle and pitch of the low-speed agitator 312 are designed according to the material characteristics. The multi-layered blades of the high-speed agitator 322 are staggered in the circumferential direction to enhance the shearing and dispersing effect.

[0022] Working principle and beneficial effects of the present invention: During operation, material is fed into the horizontally positioned cylinder 1 through the top feed inlet 11. The bottom drive motor 3131 is activated, and the low-speed agitator 312 rotates, pushing the material from the bottom upwards along the cylinder wall, forming macroscopic axial and radial circulation to prevent material from sticking to the wall. Simultaneously, the side drive motor 3231 is activated, and the high-speed agitator 322 rotates at high speed, generating strong impact and shearing forces on the material passing through its working area, breaking up agglomerated particles. The low-speed agitator is responsible for macroscopic conveying and feeding, while the high-speed agitator is responsible for microscopic dispersion; together, they achieve a "kneading"-like, thorough mixing of the material.

[0023] After mixing is complete, the tilting drive device 42 is activated, pushing the cylinder 1 to tilt around the bottom hinge shaft. The material flows under gravity and is eventually completely discharged from the side outlet 12. For extremely high viscosity materials, a low-speed stirring paddle 312 can be run at a low speed during the tilting process to assist in scraping and conveying the material, ensuring clean discharge without residue.
