Description

Technical Field

[0001] The utility model relates to the technical field of desludging classifier accessories, in particular to an assembled spiral blade. Background Art

[0002] In a desludging classifier, spiral blades use their rotational motion to separate materials into different grades based on particle size, specific gravity, and settling velocity in the liquid. Fine particles, due to their lower specific gravity, tend to float in the water and be discharged through the overflow pipe. Coarse particles, due to their higher specific gravity, settle more quickly and are pushed by the spiral blades toward the upper portion of the classifier and discharged.

[0003] Most existing spiral blades are integrated. During the desludging process, if there are hard and large particles in the material, these particles may directly scratch or wear the blades, thereby affecting the service life of the equipment. Since the blades are of an integral design, problems may require replacement of the entire blade. Patent publication number CN215234982U discloses a mining spiral classifier, which includes a bracket, a circular arc-shaped trough body disposed on the frame, a spiral shaft disposed in the circular arc-shaped trough body, and a drive device for driving the spiral shaft to rotate. The spiral shaft includes a shaft body and a plurality of spiral blades disposed on the outer periphery of the shaft body, and the plurality of spiral blades are spirally wound around the shaft body.

[0004] The spiral blades in the above-mentioned classifier are welded and connected, which makes it difficult to replace parts of the blades when they are worn. To solve the above problem, an assembled spiral blade is proposed. Utility Model Content

[0026] See also Figures 1-4 In this embodiment, an assembled spiral blade includes a rotating frame 10, an arc-shaped paddle 12 and a positioning sleeve 13;

[0027] The rotating frame body 10 includes three groups of positioning rods 18 and a connecting frame 19 for supporting the three groups of positioning rods 18. The positioning rods 18 are connected to the arc-shaped clamping seat 15.

[0028] There are a plurality of arc-shaped picks 12, and the arc-shaped picks 12 are arranged in a spiral manner;

[0029] The arc-shaped snap-fit seat 15 is provided with an arc-shaped groove 16 for the end of the arc-shaped pick 12 to be clamped in. There is a mounting notch between adjacent arc-shaped picks 12. The positioning sleeve 13 is sleeved on the connection between adjacent arc-shaped picks 12. The bottom of the positioning sleeve 13 is connected to the fixing plate 14.
