Description of drawings
Fig. 1 is the PLC control principle figure of the filter bag surface deashing device of welding robot human unit deduster of the present invention.
Fig. 2 is the field control schematic diagram of the filter bag surface deashing device of welding robot human unit deduster of the present invention.
The specific embodiment
The filter bag surface deashing device of welding robot human unit deduster of the present invention comprises PLC(Programmable Logic Controller,
Programmable logic controller (PLC)), auxiliary reclay, electromagnetic impulse valve, blower fan.The PLC output is controlled electromagnetic impulse valve by auxiliary reclay, and electromagnetic impulse valve is installed on the winding-up pipeline of blower fan, and the winding-up pipeline of blower fan stretches into filter bag.
Control section adopts PLC control, and it is powerful that PLC has stable performance, and control is convenient, can adjust the output point number, is convenient to expansion, and the deashing control mode is optional: regularly, level pressure, manually.
Regularly deashing is a kind of time PLC loop cycle control auxiliary reclay by artificial setting, thereby the control electromagnetic impulse valve makes compressed air carry out jetting deashing by the blower fan spout to filter bag.
Manually deashing is a kind of manual control auxiliary reclay, thereby the control electromagnetic impulse valve makes compressed air carry out jetting deashing by the blower fan spout to filter bag.
When adopting the level pressure purge mode, also need pressure difference transmitter, the pressure differential that described pressure difference transmitter monitoring deduster is imported and exported, described pressure difference transmitter output is connected to PLC.The course of work of the level pressure purge mode of the filter bag surface deashing device of this welding robot human unit deduster is as follows: when the flue gas flow that enters into deduster, when concentration changes, the Dust Capacity that unit interval accumulates in the filter bag outside also changes, the pressure differential that deduster is imported and exported also changes, when inferior pressure differential reaches setting value, the output point output signal of pressure difference transmitter, PLC starts working and opens electromagnetic impulse valve one by one, makes compressed air carry out jetting deashing by the blower fan spout to filter bag.
The compressed air of above-mentioned three kinds of modes by the blower fan spout to the detailed process that filter bag carries out jetting deashing is: filter bag expands suddenly, under the effect of back draught, the dust that invests the bag table hightails filter bag and falls into ash bucket, thereby reach the effect that flue gas that welding process is produced purifies, dust is discharged by unloading valve, looks how many arrangement personnel of Dust Capacity and regularly clears up and get final product.
If the deduster air quantity is enough big, can be applicable to many welding equipments and work simultaneously, electromagnetic impulse valve only need be set at the winding-up pipeline of corresponding each blower fan be used for closing the corresponding dirt pits that removes, the winding-up pipeline is unsettled layout aloft, saves the space.Pulse width and the interpulse period of electromagnetic impulse valve are adjustable, can satisfy the influence that dust sucting point fluctuates and brings to the deduster dust removing effects under the different operating modes, though the cost of electromagnetic impulse valve PLC in early stage drops into bigger than normal, but later maintenance, change very convenient, the change input cost is little, only need change program down, essentially no cost drops into, and system works is stable, be difficult for ging wrong, can realize manual control by the program setting, automatically control and Long-distance Control can realize interlock with whole system, it is just passable, simple to operation that host computer only starts for point.
Please consult Fig. 1 and Fig. 2 simultaneously, employing PLC is that the concrete principle of controlling is as follows:
The programme-control flow process: the PLC input is totally 7 inputs, I0.0 is automatic run signal input point, I0.0 connects, PLC enters automatic running status, I0.1 is manual run signal when moving automatically, I0.1 connects, automatically operation disconnects, change manual state over to, at this moment need to manually boot blower fan and electromagnetic impulse valve, I0.2 to I0.5 is 1# ~ 4# electromagnetic impulse valve start button, driving is connected four auxiliary reclays of MKA1 ~ MKA4 of 4 outputs, and four auxiliary reclay contacts are connected with four pulse action indicator lamp MHR1～MHR4 with on-the-spot four electromagnetic impulse valve MYV1～MYV4 respectively, and I0.6 is the run signal that feeds back to PLC behind the fan starting, come decision-making system whether to break down by run signal, be connected the collector BKA1 of other two outputs of PLC and operation and the fault-signal that BKA2 is collection in worksite control centre.
The electromagnetic impulse valve course of work: PLC starts, after first pulse valve connection of back in 8 seconds (time is adjustable) 0.14 second, pressure (adjustable in pressure) with 0.35MPa is blown into compressed air in the filtration cloth bag of deduster, 10 seconds (time is adjustable), back second pulse valve started, so circulation ..., start first pulse valve again behind the 4th pulse valve and stop to signal up to the outside.
The above is only for the preferred embodiment of the invention; not in order to limit the invention; all in the invention spirit and principle within do any modification, be equal to and replace and improvement etc., all should be included within the protection domain of the invention.
