Problems solved by technology

The disadvantages of this solution are: the contact between the brush and the rotor is worn during work, and the brush needs to be replaced frequently for normal work; when the brush and the rotor are connected during commutation, electric sparks interfere with electrical equipment, which has a greater impact on the power grid. Large impact; the poor ability of the analog circuit to adapt to external interference signals causes the negative pressure adjustment to be unstable; when the motor starts to work, it has a serious impact on the power grid; Causes more wear and tear on the brushes
During the peak production period, it is difficult for the enterprise to ensure the stability of the equipment, the production organization is chaotic, and the production schedule is easily affected

Abstract

The invention discloses an industrial dedusting device which comprises a garbage collection can, a can cover, a suction pipe and a fan device, wherein the fan device comprises a mechanical part and a circuit part, and also comprises a fan blade outer cover, a motor, a front end cover, a shell and a rear end cover; the motor drives a fan blade assembly to rotate, the motor is arranged in a motor cavity, the fan blade assembly is arranged in a fan blade cavity, the motor is a permanent magnet direct-current synchronous motor or a brushless direct-current motor; the circuit is electrically connected with the motor; the motor comprises a direct-current brushless stator winding, a permanent magnet, a direct-current brushless motor rotor and a bearing; the circuit comprises a CPU, a digital control circuit, a power contravariant unit, a voltage-reducing circuit and an energy-storing and filtering unit; and a power supply contravariant unit is arranged between the energy-storing and filtering unit and an input power grid. The industrial dedusting device can effectively reduce the maintenance cost, is stable in controlling the motor and the negative pressure, can eliminate the impact to the power grid during the work, and can generate high negative pressure at low speed.

Description

technical field [0001] The invention relates to the field of dust removal equipment, in particular to an industrial dust removal device widely used in textile, clothing, automobile cleaning and other industries to collect industrial liquid, thread ends, waste cloth and other textile wastes. Background technique [0002] Existing industrial dust removal equipment, such as industrial vacuum cleaners and dust collectors, mostly use a brushed DC motor to drive the fan blades to rotate to generate negative pressure, and use an analog circuit to control the speed of the motor to adjust the size of the negative pressure. The fan blades use a single stage. Fan blades extract air. The disadvantages of this scheme are: the brushes contacting the rotor are worn during operation, and the brushes need to be replaced frequently for normal work; when the brushes are connected to the rotor during commutation, sparks are generated to interfere with electrical equipment, which has a greater i...
