Description

A spiral channel constant temperature heating vertical mixer

technical field

The invention relates to a constant-temperature heating industrial mixer, in particular to a one-armed mixer with a spiral water channel for constant temperature heating suitable for stirring high-viscosity liquids.

Background technique

The mixer is a multi-functional and efficient equipment that integrates stirring, dispersing and mixing. Stirring of some highly viscous materials requires heating to reduce the viscosity of the material, thereby reducing the stirring power and improving the stirring efficiency, and the stirring paddle continuously works on the material during the stirring process, which makes the temperature of the material change during the stirring process, and some are sensitive to temperature. The material requires a stable temperature while stirring. These all require that the stirring equipment has a good temperature control and adjustment system.

When the mixer is feeding, cleaning and changing the mixing blades, it will bring great convenience to the operation if the mixing blades can be moved out of the barrel. Few of the existing stirring equipment have automatic lifting mechanisms, and the lifting structure mostly uses hydraulic devices to lift the stirring device as a whole, which is complicated and consumes a lot of energy.

For high-viscosity materials, it is necessary to increase the extrusion equipment to output the mixed materials after stirring. Many patents have been formed on the mixer. For example, CN100490960C discloses a liquid mixer, which provides a rotating disk to exchange two mixing barrels to align the mixing device and the extrusion device respectively. The base is provided with a shaft in the middle of the top. The shaft seat is combined with a rotating disk in a rotatable form for stirring and extrusion. CN102847460A discloses a stirrer, which includes a motor, a sliding device, a stirring device, an input end connected to an output end of the motor, and an output end connected to a crankshaft, which can effectively accelerate the diffusion and dissolution of electrolytic raw materials. CN2425702Y discloses a horizontal viscous liquid mixer, including a motor, a reducer, a transmission device, a mixing drum, a stirring shaft, etc., and a scraper is provided on the side of the mixing blade B, so that the bottom of the mixing drum has no settlement and no dead angle. CN101711958A discloses a mixer, which can be driven by a motor to rotate, and is provided on the drive shaft as a part of the drive unit. The inner wall of the container receiver is cylindrical, and the inner wall of the container receiver has a plurality of preferably arranged according to the grid. through hole. It can be seen from the above patents that there are many problems, such as the mixer cannot be heated or the heating is constant, most of them use hydraulic systems, the volume is too large, the structure is complicated, and the power consumption is too large.
