the main shaft of the horizontal walking motor (17) starts to rotate and drives the two first driving chain wheels (18) to synchronously rotate, the two first driving chain wheels (18) synchronously rotate and simultaneously drive the vertical walking part mounting plate (22) to generate displacement, when the automatic induction probe (34) in the washing and drying ring (31) induces the induction screw (35), the air drying fan (40) is started, the automatic induction probe (34) sends a signal to the PLC control system (39), the PLC control system (39) controls the air pipe cut-off valve (42) and the corresponding control valve (4) to be opened, meanwhile, the vertical walking motor (24) is controlled to start, the main shaft of the vertical walking motor starts to rotate, the two second driving sprockets (28) are driven to synchronously rotate, and the two second driving sprockets (28) synchronously rotate and simultaneously drive the washing and drying ring (31) to move upwards through the second chain (29) and the washing and drying part mounting plate (30);

when the washing and drying ring (31) moves upwards, wind generated by the air drying fan (40) is subjected to heat exchange through the shell pass of the air heat exchanger (41) and then is dried and blown to the dust removal cloth bag (8) through the air pipe cut-off valve (42), the control valve (4), the hose (5) and the washing nozzle (33);

step 10: in the process of drying and spraying the dust removal cloth bag (8), the air drying fan (40) and the vertical traveling motor (24) are in a running state, the second chain (29) drives the washing and drying ring (31) through the washing and drying part mounting plate (30) to dry and spray the dust removal cloth bag (8) from bottom to top, and when the automatic induction probe (34) in the washing and drying ring (31) senses the induction screw (35), the automatic induction probe (34) controls the vertical traveling motor (24) to stop running through the PLC control system (39);

after the vertical walking motor (24) stops running, the PLC control system (39) enters a top-down drying and blowing program, the PLC control system (39) controls the vertical walking motor (24) to rotate reversely, the second chain (29) drives the washing and drying ring (31) to run from top to bottom through the washing and drying part mounting plate (30), hot air is used for drying and blowing the dust removal cloth bag (8) from top to bottom through the washing nozzle (33), and the PLC control system (39) controls the vertical walking motor (24) to stop running until the automatic induction probe (34) in the washing and drying ring (31) senses the induction screw (35);

the bottom-up drying and blowing and the top-down drying and blowing are a drying and blowing period, and the time of the drying and blowing period is 40-50 s;

step 11: after the drying and blowing period in the step 10 is finished, the PLC control system (39) controls the horizontal walking motor (17) to start, and at the moment, the washing and drying ring (31) is still positioned at the bottom of the dust removal cloth bag (8);

the main shaft of the horizontal walking motor (17) starts to rotate and drives the two first driving sprockets (18) to synchronously rotate, the two first driving sprockets (18) synchronously rotate and simultaneously drive the vertical walking part mounting plate (22) to generate displacement, when an automatic induction probe (34) in the washing and drying ring (31) induces the next induction screw (35), the automatic induction probe (35) sends a signal to a PLC control system (39), the PLC control system (39) controls the vertical walking motor (24) to start, the main shaft of the vertical walking motor starts to rotate and drives the two second driving sprockets (28) to synchronously rotate, and the two second driving sprockets (28) synchronously rotate and simultaneously drive the washing and drying ring (31) to move upwards through the second chain (29) and the washing and drying part mounting plate (30); repeating the step 10 to dry the next dust removal cloth bag (8) in one drying and blowing period;

step 12: in the step 4, the step 6, the step 8, the step 9 and the step 11, the PLC control system (39) respectively controls the plurality of horizontal traveling motors (17), and the plurality of horizontal traveling motors (17) run asynchronously;

step 13: after all the dust removing cloth bags (8) are dried, the PLC control system (39) controls the hydraulic oil cylinder (13) to be started, so that the telescopic end of the hydraulic oil cylinder (13) retracts, the left turning plate (11) and the right turning plate (12) are driven to move downwards, and at the moment, the cloth bag dust remover enters a normal dust removing operation state.
