Background

The bag type dust collector is widely used in field practice, and the ash removal is an important link in the bag type dust collector and can ensure the normal operation of the bag type dust collector.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, the ash removal control system of the bag-type dust collector comprises a power module 1 with a power inlet, a control module 2 electrically connected with the power module 1, a control end connection terminal 3 for electrically connecting with a blowing valve 5, and a sensor electrically connected with the control module 2; also included is a regulator 4; the control end wiring terminal 3 is electrically connected with the control module 2 through the regulator 4, the sensor is a gray sensor, and the gray sensor is arranged in a cloth bag of the bag type dust collector.

Wherein, the power module 1 generally adopts a conventional AC220V power supply; the control module 2 is a core component of the bag type dust collector ash removal control system, and an industrial grade single chip microcomputer is generally adopted as the control module 2; a corresponding control program is generally embedded in the control module 2.

The gray sensor is an analog sensor which comprises a light emitting diode and a photoresistor, and the light emitting diode and the photoresistor are arranged on the same surface. The gray sensor utilizes the principle that the reflection degrees of the detection surfaces with different colors to light are different, and the photoresistor detects the color depth of the light returned by the different detection surfaces according to the principle that the resistance values of the light returned by the photoresistor are also different. Within the effective detection distance, the light-emitting diode emits white light which irradiates the detection surface, the detection surface reflects part of light, and the photoresistor detects the intensity of the light and converts the light into an analog signal, so that the purpose of detecting the dust content is achieved.

The regulator 4 is a conventional component known to those skilled in the art, and is capable of comparing the dust content detected by the gray sensor with a set value, and generating an output signal according to a certain regulation rule after obtaining a deviation to control the operation of the corresponding blowing valve to eliminate the deviation amount, so that the dust content in the cloth bag is kept near the set value, which is beneficial to reducing the control cost and improving the control reliability.
