Horizontal helix solid-liquid mixing apparatus

Abstract

The invention discloses a horizontal helical solid-liquid mixing unit, which comprises a speed regulating motor, a bearing pedestal and a cylindrical mixing chamber, wherein the feeding end of the mixing chamber is provided with a solid feed opening and a liquid feed opening, and the discharging end of the mixing chamber is provided with a discharge opening and an exhaust opening; the bottom of the mixing chamber is provided with a cleaning opening; the center of a cylinder is provided with a stirring shaft both ends of which are connected with the bearing pedestal through a rotating shaft respectively; the speed regulating motor drives the rotating shaft to rotate; a helical pitched turbine paddle is fixed on the stirring shaft, and the angle of the helical pitched turbine paddle which is inclined to the stirring shaft is between 2 and 6 DEG; and the inclination angle of a blade of the helical pitched turbine paddle and a disc surface is between 3 and 9 DEG. Compared with the prior art, the mixing unit has high mixing efficiency, high speed and uniform mixing of materials, does not leave dead angle, and is suitable for continuous operation. Moreover, the device has a simple overall structure, and is convenient to assemble, disassemble and clean.

Description

technical field [0001] The invention relates to a solid-liquid mixing device, in particular to a horizontal spiral solid-liquid mixing device. Background technique [0002] At present, the mixing of two items of solid and liquid basically adopts the method of adding the two items into the reactor in a certain proportion, and then realizes the mixing by mechanical stirring or bubbling stirring. But for powders with finer particle size, when mixed with liquid, the liquid only dissolves the surface of the powder block and cannot penetrate into the inside of the powder, failing to achieve the purpose of fully mixing the solid and liquid. In the case of requiring high mixing uniformity, multiple mixings are required to meet the requirements, which will inevitably increase the process cost. In addition, during the operation of some solid-liquid mixing devices, the internal pressure increases due to the rotation of the stirring blades. Although some devices are equipped with spare...

AI Technical Summary

Problems solved by technology

Although this device improves the solid-liquid mixing to a large extent, the internal pressure increases due to the rotation of the stirring blades, which creates great resistance to the material supply and the flow of the mixed material, although the device is equipped with a spare feed tube, but the difficulty of smoothly supplying powder materials still exists
