The invention discloses a filter screen anti-blocking device for dust collection equipment for
textile. The filter screen anti-blocking device comprises a dust collecting box, a feeding port is formedin one side of the dust collecting box, a filter screen is arranged on the other side of the dust collecting box, an
air chamber is fixedly connected to the side, close to the filter screen, of the dust collecting box, a baffle is connected into the
air chamber in a sealed mode, and an
impeller is arranged in the
air chamber; and a rotation center of the
impeller is fixedly connected with a rotating shaft, the rotating shaft penetrates through the baffle and is fixedly connected with a motor, and the motor is connected with a conductive structure. According to the invention, when the mesh ofthe filter screen is blocked, thermoelectricity is formed through the
temperature difference generated by the residual heat of the motor, so that an electric plate close to one side of the filter screen is electrified, and dust in the filter screen is sucked under the action of
electrostatic adsorption; and on the other hand, under the condition that the
internal energy of the motor is larger, thevoltage at both ends of the motor is reduced through a
thermistor, and a current is applied to a conductor ring, so that the temperature of the motor is lowered by the principle of
temperature difference refrigeration, and the motor is prevented from being burnt out.
