Problems solved by technology

The conventional dispersing disc is formed by welding the zigzag dispersing disc and the shaft sleeve, but because the dispersing disc is thin and the bushing is very thick, the deformation of the thinner dispersing disc cannot be controlled during the welding process, which affects the stability. It is also difficult to control its flatness when the disk is shaped

Embodiment Construction

[0011] The present invention will now be further described in conjunction with specific examples, and the following examples are intended to illustrate the present invention rather than further limit the present invention.

[0012] Such as figure 1 A toothed disc turbine agitator shown includes a shaft sleeve 1 and a dispersion disc 2. The shaft sleeve 1 is connected to the dispersion disc 2 through a butterfly-shaped pressing plate 3. There are two butterfly-shaped pressing plates 3, which are sequentially arranged from top to bottom. It is the first butterfly-shaped pressing plate 31 and the second butterfly-shaped pressing plate 32. The first butterfly-shaped pressing plate 31 is located at the upper position of the dispersion disc 2, the second butterfly-shaped pressing plate 32 is located at the lower position of the dispersion disc 2, and the second butterfly-shaped pressing plate is located at the lower position of the dispersion disc 2. The lower position of 32 is prov...

Abstract

The invention relates to a stirring device, and especially relates to a toothed disk turbine-type stirring device. The toothed disk turbine-type stirring device comprises a shaft sleeve and a dispersing disk. The shaft sleeve is connected with the dispersing disk through butterfly pressure plates. There are two butterfly pressure plates, which are a first butterfly pressure plate and a second butterfly pressure plate from top to bottom. The first butterfly pressure plate is positioned on the upper part of the dispersing plate, and the second butterfly pressure plate is positioned on the blower part of the dispersing plate. A round nut used for fixing the shaft sleeve is arranged on the lower part of the second butterfly pressure plate. According to the invention, the clamping-type butterfly pressure plates are used for fixing the dispersing plate and the shaft sleeve, and welding is not needed. With the pre-tightening force between the two butterfly pressure plates, the dispersing plate can be firmly clamped, and two planes can be completely flattened. The two butterfly pressure plates has butterfly shapes and light weights, such that the effective mass of the stirring device at the end of a stirring shaft is reduced, critical rotation speed is improved, shaft diameter is reduced, and cost is reduced.

Description

technical field [0001] The invention relates to a stirring device, in particular to a toothed disk turbine stirrer. Background technique [0002] The toothed disk turbine agitator has high shear force performance under high-speed rotation, so it is often used for dispersion mixing with large differences in the physical properties of the two phases. Since the dispersing disc is generally used at a high stirring speed, the balance of the dispersing disc itself is highly required. The conventional dispersing disc is formed by welding the zigzag dispersing disc and the shaft sleeve, but because the dispersing disc is thin and the bushing is very thick, the deformation of the thinner dispersing disc cannot be controlled during the welding process, which affects the stability. It is also difficult to control its flatness when the disk is shaped. Contents of the invention [0003] The technical problem to be solved by the present invention is: Based on the above problems, the p...
