Problems solved by technology

At present, there are two kinds of ore washing machines used: spiral ore washer and cylindrical ore washer. The spiral ore washer is generally a single spiral ore washer, which makes its production efficiency very slow. For this reason, although some enterprises design A double-helix washing machine has been produced, but its effect is still unsatisfactory. It is particularly important to design a better washing machine

Abstract

The invention discloses a spiral ore washing machine of a frame-free combined type permanent magnet synchronous motor direct drive, wherein the spiral ore washing machine comprises at least two rotating shafts with spiral blades, the rotating shaft is arranged on the machine frame, and the rotating shafts are arranged in parallel; the upper end of the rotating shaft is fixedly connected with the driving device, and the lower end of the rotating shaft is connected with the driving device through a transmission gear assembly; and the driving device is a frameless combined type permanent magnet synchronous motor, each frameless combined type permanent magnet synchronous motor comprises a stator assembly and a rotor assembly, and the stator assembly is fixedly arranged on the machine frame, provides a rotary magnetic field for the rotor assembly, and the rotor assembly is connected with the rotary shaft; the stator assembly comprises a stator winding and a stator iron core, wherein the stator winding and the stator iron core are cast into a fan-shaped block which is integrally formed; the plurality of fan-shaped block ring cloth and or is arranged on the rotor assembly in a surroundingmode. According to the invention, the middle driving link of the transmission part is reduced. The driving mode and the structure are simplified, the driving efficiency is improved, and direct driving of equipment is realized.

Description

technical field [0001] The invention relates to the field of mining production equipment, in particular to a spiral ore washing machine directly driven by a frameless combined permanent magnet synchronous motor. Background technique [0002] The ore washing machine is a large-scale equipment used to wash ore and stone materials in mines, steel, metallurgy, chemical industry, building materials, etc. The ability of the ore washing machine to clean ore is a standard for testing the quality of the ore washing machine; the spiral washing machine is Using the buoyancy of water, the dust and impurities are separated from the sand; through the agitation of the spiral plate, the purpose of filtering water to remove impurities and lifting and conveying is achieved. Secondly, during the lifting process, mixing work was also carried out. Secondly, the spiral washing machine has a long spiral body, good sealing system, simple structure, strong processing capacity, and convenient mainte...
