Twin-spiral mixer

Abstract

The invention relates to a mixing apparatus, specifically to a twin-spiral mixer. The twin-spiral mixer comprises a cylindrical shell and a rotating shaft. A horizontal tumbler which is connected with the rotating shaft is arranged inside the cylindrical shell. The cylindrical shell is provided with a liquid feed inlet which is connected with a storage tank through a pipeline. A heat coil is arranged inside the storage tank. The twin-spiral mixer has a simple structure and can be used to heat a liquid material according to an actual situation. In addition, by the adoption of a spray device, all-around full uniform mixing of a solid material and a liquid material can be realized. Mixing precision is high as well as the mixing efficiency. Therefore, energy consumption is reduced to some extent. The twin-spiral mixer is easy to popularize and use.

Description

technical field [0001] The invention relates to a mixing device, in particular to a double screw mixer. Background technique [0002] Twin-helix mixer is a commonly used mixing equipment. However, when mixing liquid and solid, the commonly used twin-helix mixer mainly has the following defects: 1. When the ambient temperature is too low, the viscosity of the liquid material is relatively high , it is not easy to enter the cylinder, so that the liquid material and the solid material are mixed unevenly and the reaction is insufficient; 2. When the reaction in the mixer requires the liquid material to have a certain feed temperature, the liquid material needs to be heated by another device. The operation is cumbersome; 3. The existing mixer is usually provided with a liquid feed port and a solid feed port on the cylinder cover. The liquid feed port is usually fixed. When the liquid material is added to the feed port through the feed port When inside the cylinder, due to the ho...

[0002] Twin-helix mixer is a commonly used mixing equipment. However, when mixing liquid and solid, the commonly used twin-helix mixer mainly has the following defects: 1. When the ambient temperature is too low, the viscosity of the liquid material is relatively high , it is not easy to enter the cylinder, so that the liquid material and the solid material are mixed unevenly and the reaction is insufficient; 2. When the reaction in the mixer requires the liquid material to have a certain feed temperature, the liquid material needs to be heated by another device. The operation is cumbersome; 3. The existing mixer is usually provided with a liquid feed port and a solid feed port on the cylinder cover. The liquid feed port is usually fixed. When the liquid material is added to the feed port through the feed port When inside the cylinder, due to the horizontal rotating arm inside the cylinder, the liquid material will often fall on the horizontal rotating arm and the full mixing of the liquid material and the solid material cannot be achieved, resulting in low mixing accuracy and poor mixing efficiency.
