Stirrer with angle-adjustable stirring blades

Abstract

The invention discloses a stirrer with angle-adjustable stirring blades. An upper cover plate is arranged above a tank body, inclined spraying heads are symmetrically arranged on the lower side in the upper cover plate, a clear water tank is arranged on the outer side of the tank body, a connecting frame is arranged on the upper side in the tank body, a main rotating shaft is arranged between the upper cover plate and the connecting frame in a penetrating mode, and a preliminary mixing mechanism is arranged on the main rotating shaft below the connecting frame; and a hinged mixing mechanism is arranged on the inner wall of the tank body through a guide rail groove in the inner side of a fixing ring. Materials entering the tank body are preliminarily scattered and mixed through an autorotation stirring rod of the preliminary mixing mechanism, then through arrangement of the hinge mixing mechanism and a guide rail groove, when the hinge mixing mechanism is used for mixing, a hinge connecting rod jumps in a wave mode in the materials, the stirring angle of stirring blades is changed, the mixing effect is further improved, the hybrid processing time is reduced and the production efficiency is increased. Meanwhile, the inclined spraying head can automatically wash the interior of the tank body, the situation that the device is manually disassembled for cleaning is avoided, and the device is convenient, rapid and time-saving and labor-saving.

Description

technical field [0001] The invention relates to the technical field of stirring equipment, in particular to a stirrer with adjustable stirring blade angles. Background technique [0002] Stirrer refers to a device that makes liquid and gas medium forced convection and uniform mixing. The type, size and speed of the stirrer have an impact on the distribution of stirring power between the overall flow and turbulent flow. Generally speaking, the turbine stirrer The power distribution of the propeller is beneficial to the turbulent pulsation, while the propeller stirrer is beneficial to the overall flow; [0003] Existing agitators are widely used and have the purpose of uniformly mixing fluid or powdery solids. For existing agitators, the common mixing method uses the rotation of the mixing shaft to drive the stirring blades to rotate, so as to realize the mixing of fluids or powdery solids.

Problems solved by technology

[0003] Existing agitators are widely used and have the purpose of uniformly mixing fluid or powdery solids. For existing agitators, the common mixing method uses the rotation of the mixing shaft to drive the stirring blades to rotate, so as to realize the mixing of fluids or powdery solids. Mixing, but the mixing effect of this mixing method is poor. The mixed fluid or powdery solid can only rotate with the direction of rotation of the stirring blade. There is no reversing structure in the middle, and the fluid or powdery solid cannot be effectively rotated. Reversing, and then the mixing uniformity is low, it is difficult to meet the needs of the agitator, and the existing agitator needs to be manually disassembled for internal flushing, which is very inconvenient and time-consuming. Therefore, the present invention proposes an adjustable agitator blade angle The agitator to solve the problems in the prior art
