Detailed description of the invention
Referring to figs. 1 through Fig. 5, the utility model filter cartridge dust remover embodiment is described further.
But the utility model can realize in various different formats, and the utility model should not be construed as and is limited to exemplary embodiment set forth herein.There is provided exemplary embodiment to contribute to more fully understanding the utility model.
As shown in Figure 1, a kind of filter cartridge dust remover, comprises housing 1, is provided with the filter cylinder 2 for dedusting in housing 1, and the axis direction of filter cylinder 2 is provided with pulse valve 3, housing 1 is provided with the infrared detecting device for detecting filter cylinder 2 outer surface dust thickness.Infrared detecting device comprises infrared circuit A, monostable flipflop B and on-off circuit C, and infrared circuit A comprises infrared transmitter 5, infrared remote receiver 6.On-off circuit is metal-oxide-semiconductor, and the control pole (i.e. grid) of metal-oxide-semiconductor is connected with the output of monostable flipflop, for the duty of control impuls valve.
Infrared transmitter 5 and infrared remote receiver 6 form a signal detection mechanism, under general case, infrared remote receiver 6 receives the signal launched from infrared transmitter 5 constantly, when the dust thickness of filter cylinder 2 outer surface acquires a certain degree, stop that infrared remote receiver 6 receives the infrared signal of launching from infrared transmitter 5, this process can be converted to the signal input of infrared detecting device, by monostable flipflop process and feedback, gauge tap circuit turn-on, signal is transferred to pulse valve 3 by electrical connection, the duty of control impuls valve 3, pulse valve 3 Received signal strength inputs, start working, blowback air is carried out to filter cylinder 2 inside, the dust of filter cylinder 2 outer surface is dropped, avoid blocking filter cylinder 2, affect service efficiency.Contrast pulse valve 3 of the prior art, the control of pulse valve 3 is controlled by microcomputer, by being that frequency carries out work, so in varying environment, within pulse valve 3 work period, the dust of its filter cylinder 2 outer surface can't affect the working effect of filter cylinder 2 deduster, timing dusting and not according to actual conditions carry out dedusting, inevitably brings larger power attenuation, increases enterprise's production cost, the environmental protection cost of also covert increase, is unfavorable for the popularization that environmental protection of enterprise is realized simultaneously.
The circuit diagram of infrared detecting device as shown in Figure 2-5, by T1 slot optical coupling (infrared transmitter 5 and infrared remote receiver 6), IC1 monostable flipflop, on-off circuit.Slot optical coupling lTR9608, R1, R2 form photoelectric detective circuit, and the dust thickness be responsible for detecting converts voltage pulse signal to.Slot optical coupling is made up of infrared transmitter 5 and phototriode, and during work, infrared transmitter 5 sends IR and projects on phototriode through the groove of optocoupler, phototriode conducting, colelctor electrode output low level; When IR is interdicted by dust, phototriode ends, and colelctor electrode exports high level.Block a slot optical coupling and export a pulse, the number of therefore pulse is exactly the number of times that on-off circuit triggers, the number of times of namely pulse valve 3 work.R3, C2, C3 and IC1 form monostable flipflop.Its effect carries out shaping to the pulse signal that slot optical coupling transmits, and removes noise signal, improves antijamming capability.The model of IC1 is NE555, is connected in timing capacitor by input TH and discharge end DIS in circuit simultaneously, is high level when trigger end TR is flat.After power supply is connected, because TR pin is high level, the output of IC1 is low level, inner discharge tube conducting, DIS holds conducting over the ground, and the voltage on timing capacitor C3 is 0V, TH input is also that the output of 0V, IC1 is always low level state, and this state is exactly the stable state of monostable flipflop.Low level is become from high level when slot optical coupling exports, and time this low level <1/3VCC (Vcc=5V is the supply voltage of IC1).The output of IC1 reverses, and OUT end exports and becomes high level by low level, meanwhile, and the discharge tube cut-off of IC1 inside.Power supply is charged to C3 by R3, and temporary stable state starts.Through to after a while, as voltage >2/3Vcc on C3, monostable flipflop reverses, OUT exports and becomes low level from high level, discharge tube conducting, C3 holds repid discharge by the DIS of IC1, and original stable state got back to again by monostable flipflop.Measured object often blocks a slot optical coupling, and it is the pulse of td that monostable flipflop exports a width, and this pulse can control metal-oxide-semiconductor M1 conducting, and the M in control impuls valve 3(and Fig. 2) work.C1 is filter capacitor, can improve monostable flipflop job stability.
Preferably, described metal-oxide-semiconductor M1 adopts NMOS tube, and its operating characteristic is high level conducting.
Preferably, the corresponding filter cylinder 2 of described housing 1 is provided with air intake vent 4, and the corresponding air intake vent 4 of infrared detecting device is placed.Corresponding for infrared detecting device air intake vent 4 is arranged, fast reaction can be made to the dust of filter cylinder 2 outer surface the most fast, avoid the efficiency of dust collection and the effect that affect this filter cylinder 2 deduster.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
