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 without a frame type permanent magnet synchronous motor direct drive. The spiral ore washing machine comprises at least two rotating shafts with spiral blades, a rotating shaft is arranged on a machine frame, and the rotating shafts are arranged in parallel; the upper end of the rotating shaft is fixedly connected with a driving device, and thelower end of the rotating shaft is connected with the driving device through a transmission gear assembly; the driving device is a frameless type permanent magnet synchronous motor, and each framelesstype permanent magnet synchronous motor comprises a stator assembly and a rotor assembly; the stator assembly is fixedly arranged on the machine frame, a rotary magnetic field is provided for the rotor assembly, and the rotor assembly is connected with the rotating shaft; and the stator assembly comprises a stator base, a stator iron core and a stator winding, the stator iron core is of an integrated machining forming structure, and the stator winding is wound in the stator iron core. According to the spiral ore washing machine, the middle driving link of the transmission part is reduced, thedriving mode and the structure are simplified, the driving efficiency is improved, and direct driving of the device 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 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 maintenance; th...
