Specific embodiment

Referring to Fig. 1 and Fig. 2, the utility model mainly includes dust filtering fan frequency converter B P, start button SB2, stop botton When SB1, main contactor JC0, two intermediate relays (i.e. a line intermediate relay KA1 and two wires intermediate relay KA2), two Between relay (i.e. a line time relay KT1 and two wires time relay KT2) and two be separately mounted to storehouse mixed cotton more than two Throttle valve (being not drawn into figure) on machine filter dirt pipeline, each throttle valve include solenoid valve (the first solenoid valve V1 i.e. in figure and Second solenoid valve V2), cylinder and pneumatic plate.

Since the main dust sucting point of cotton cleaning and dust removing pipeline is in multi-mixer, in the dust filtering pipe of two multi-mixers Pneumatic plate is installed on road, for the dust filtering negative pressure that throttles, solenoid valve and cylinder is installed on pneumatic plate, is connected and pressed by tracheae On contracting air to cylinder, the voltage rating of solenoid valve is 220V, when solenoid valve obtains it is electric when, compressed air is by solenoid valve, driving The piston rod of cylinder stretches out, and pneumatic plate is pushed to open dust filtering pipeline；When solenoid valve power loss, cylinder piston rod is retracted, and pulls gas Dynamic plate closes dust filtering pipeline.Electrical aspect, original equipment electric wiring are, when a line multi-mixer starts, a line contactor JC1 is attracted, and when a line multi-mixer stops, a line contactor JC1 power loss is disconnected；When two wires multi-mixer starts, two wires Contactor JC2 is attracted, and when two wires multi-mixer stops, two wires contactor JC2 power loss is disconnected.It is mixed in the more storehouses of a line after improvement Increase a line time relay KT1 and a line intermediate relay KA1 on cotton machine；Increase the two wires time on the multi-mixer of two wires The control coil of relay KT2 and two wires intermediate relay KA2, a line time relay KT1 and two wires time relay KT2 point It is not in parallel with the control coil of a line contactor JC1 and two wires contactor JC2, while it being attracted disconnection, a line time relay KT1 Delay with two wires time relay KT2 disconnects normally open contact and controls relay among a line intermediate relay KA1 and two wires respectively The firewire of the coil of device KA2,220V power supply is (normal by a line intermediate relay KA1 and two wires intermediate relay KA2 auxiliary contact Open), it is respectively connected to the first solenoid valve V1 and second solenoid valve V2.The wiring of dust filtering fan frequency converter B P control terminal, main contact Device main contacts JC0-1 (normally opened) control LI1, (normally opened) control LI5 of line intermediate relay main contacts KA1-1, among two wires after (normally opened) the control LI6 of electric appliance main contacts KA2-1.When blowing device power-up, first start dust filtration equipment, presses start button SB2, it is main Contactor JC0 is attracted, and main contactor main contacts JC0-1 connects Frequency Converter Control terminal LI1, and dust filtering fan frequency converter B P starts 30HZ operation, when starting a line blowing equipment by next line power on button SB4, a line time relay KT1 is attracted, and contact is connected The control coil of one line intermediate relay KA1, a line intermediate relay main contacts KA1-1 connect dust filtering fan frequency converter B P control Terminal LI5, when similarly starting two wires blowing equipment, two wires intermediate relay main contacts KA2-1 connects dust filtering fan frequency converter B P Control terminal LI6.The method of operation of dust filtering fan frequency converter B P is that LI1 is connected, and LII is connected with LI5, and LII is connected with LI6, this Three kinds of modes, dust filtering fan frequency converter B P are run to 30HZ, when LI1, LI5, LI6 are connected, dust filtering fan frequency converter B P operation To 40HZ, that is, after starting dust filtering fan frequency converter B P, electromagnetism when opening or cleaning spends a production line, on more storehouse dust filtering pipelines of operation Valve obtains electric, and pneumatic plate is opened, and carries out dust suction, the solenoid valve on inactive more storehouse dust filtering pipelines not electric, pneumatic plate pass Stopped pipe road reduces dust filtering dust sucting point, dust filtering host 30HZ operation；When opening or cleaning spends two production lines, the solenoid valve in the more storehouses of two lines is all Must be electric, pneumatic plate is opened, and since dust sucting point increases, dust filtering fan frequency converter B P is run with 40HZ, guarantees blowing equipment dust filtering Negative pressure is constant.The effect of one line time relay KT1 and two wires time relay KT2 are to be switched on one when opening two line blowings When line blowing, delay disconnects normally opened contact and disconnects by solenoid valve and Frequency Converter Control terminal delay a period of time, and at this moment more storehouses have been It closes, dust filtering is run with 40HZ, and pneumatic plate is opening state, continues to exhaust pipeline trifle in the world, and after delay, dust filtering fan becomes Frequency device BP switchs to 30HZ, and pneumatic plate is closed.

The utility model is relatively simple for structure, easy to use, and the blowing that can efficiently solve two line configurations sets For the problem of when only opening a production line, dust filtering unit main motor M wastes waste electricity, production cost is greatly saved, is applicable in In any textile mills.
