Description

Technical Field

[0001] This utility model relates to the field of homogenizer technology, and in particular to a twin-screw homogenizer. Background Technology

[0002] In modern industrial production, twin-screw homogenizers are an important material handling equipment. They utilize two intermeshing or non-intermeshing screws within a specific cylindrical structure to perform a series of operations on materials through the rotational motion of the screws, thereby achieving material homogenization. With social development, various industries have increasingly higher requirements for product quality and production efficiency. In the field of lithium battery production, the uniformity of electrode slurry directly affects the performance and stability of the battery. Twin-screw homogenizers, with their high efficiency and continuous production characteristics, can meet the needs of large-scale, high-quality production, thus promoting the rapid development of related industries.

[0003] Initially, twin-screw homogenizers were mainly used in the plastics and rubber industries. During plastic granulation, operators had to manually pour various raw materials into the hopper and adjust the screw speed using a simple control device to achieve preliminary mixing and extrusion of the materials. This operation method relied on manual experience, resulting in low production efficiency and significant human influence on product quality. With technological advancements, existing twin-screw homogenizers have seen a significant improvement in automation, widely adopting advanced control systems that can precisely control the material feed rate and screw speed parameters. However, existing equipment still has some shortcomings. During continuous feeding and discharging, dynamic metering fluctuations are large, making it difficult to accurately control the material mixing ratio and affecting the stability of product quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a twin-screw homogenizer, which aims to improve the problem of difficulty in accurately controlling the material mixing ratio in the prior art, thus affecting the stability of product quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a twin-screw homogenizer, comprising a housing and a mounting base, wherein a rotating shaft is provided on the inner wall of the housing, a material conveying section is provided at the right end of the rotating shaft, a compression section is provided in the middle of the rotating shaft, and a homogenizing section is provided at the left end of the rotating shaft; a motor is fixedly connected to the top surface of the mounting base, a reducer is provided at the output end of the motor, and the other end of the reducer is fixedly connected to one end of the rotating shaft; a feed inlet is provided at the top of the housing, and a pretreatment mechanism is provided on the top surface of the feed inlet, the pretreatment mechanism being used for pretreatment of the material.

[0006] As a further description of the above technical solution:

[0007] The pretreatment mechanism includes a protective cover, the outer wall of which is fixedly connected to the inner wall of the feed inlet. An L-shaped plate is fixedly connected to the outer wall of the protective cover. A second motor is fixedly connected to the top of the L-shaped plate. The output end of the second motor passes through the outer wall of the protective cover and is fixedly connected to a rotating roller. A gear is fixedly connected to the other end of the rotating roller. Crushing teeth are fixedly connected to the outer wall of the rotating roller.

[0008] As a further description of the above technical solution:

[0009] The left end of the outer shell is provided with a discharge port, and the outer wall of the discharge port is provided with a circular hole.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the circular hole is fixedly connected to the liquid outlet, and the bottom surface of the outer shell is provided with multiple bases.

[0012] As a further description of the above technical solution:

[0013] A heating mechanism is fixedly connected to the top surface of the base in the middle, and multiple mixing elements are fixedly connected to the outer wall of the rotating shaft.

[0014] As a further description of the above technical solution:

[0015] The top surface of the outer casing is provided with a liquid inlet, and the outer wall of the liquid inlet is provided with a valve.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the conveying section is located at the beginning of the rotating shaft, smoothly conveying the material to the compression section. The conveying section has a large screw pitch, which can push a large amount of material, ensuring that the material can smoothly enter and provide a stable material supply for subsequent processing. During the material conveying process, the material is initially mixed in the shell, and the materials of different components are initially stirred and dispersed, preparing for more uniform mixing and homogenization in the future. The screw pitch of the compression section gradually decreases, generating a compression effect on the material. As the screw rotates, the material is gradually squeezed, the volume decreases, and the density increases, thereby improving the compactness of the material and creating conditions for the fine processing of the homogenization section. The homogenization section applies high-intensity shearing, stirring and grinding action to the material, refining the material to the required particle size, so that the material reaches a highly uniform mixing state, ensuring that the quality of the homogenized product is stable and consistent.

[0022] 2. In this utility model, when some larger particles of raw materials enter the outer shell for processing, they will cause significant wear to the conveying section, compression section and homogenization section. Large particles of material are poured in from the feed hopper, and the second motor drives the rotating roller to rotate. One end of the rotating roller is fixedly connected to a gear. The two gears mesh, causing the two rotating rollers to rotate in opposite directions. The crushing teeth on the outer wall of the rotating roller work together to crush the large particles of material, making the material easier to mix and react. Attached Figure Description
