Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a double-shaft mixer special for an IBC barrel. Background Art

[0002] At present, BC barrels, namely IBC ton barrels or intermediate bulk containers, are essential tools for modern storage and transportation of liquid products. They are composed of inner containers and metal frames. The inner containers are usually blow-molded with high molecular weight and high density polyethylene, which has the advantages of high strength, corrosion resistance and good hygiene. There are liquid level scale lines on the side of the container to facilitate filling. The discharge valves are made of high density polyethylene and polypropylene to ensure the corrosion resistance of various liquid products.

[0003] The prior art has an IBC container stirring device with an authorization announcement number of CN218023345U. The patent relates to an IBC container stirring device, including a frame, a lateral sliding mechanism, a material extraction system, a filling system and a stirring system. The frame is designed with a content cavity for receiving the IBC container. The lateral sliding mechanism drives the lateral slide block to move left and right along the slide rail through a lateral cylinder. The slide block is equipped with a material extraction system, a filling system and a stirring system. The material extraction system is responsible for extracting materials from the container, the filling system is responsible for filling the materials into the target container, and the stirring system is responsible for mixing the materials. These systems are fixed on the lateral slide block through their respective driving mechanisms, realizing integrated automatic material extraction, filling and stirring operations, which not only reduces costs but also significantly improves work efficiency.

[0004] However, after the patent is installed, when performing the stirring operation, only relying on a single shaft to stir in the IBC barrel may face the problem of insufficient stirring, especially when dealing with materials with high viscosity, easy to precipitate or need to be evenly mixed, a single stirring shaft may not meet the stirring effect requirements;

[0005] In addition, the stirring shaft is an integrally formed structure with the entire stirring device, which brings many inconveniences to the cleaning and maintenance of the stirring shaft after stirring is completed. Since the stirring shaft is tightly connected to the device and cannot be easily disassembled, a large amount of manpower and time are required for cleaning and maintenance. Utility Model Content
