The electrostatic neutralization rod is formed by fixedly arranging a high voltage electrode rod in an insulation tube, a spray point is arranged on the high voltage electrode rod, and a grounding electrode steel wire, an air inlet pipe fast inserting joint and an air blowing hole are arranged on the insulation tube. The utility model has the advantages of simple structure, low cost and convenient use. The utility model can be widely used for the static elimination and dust removing in industrial production.
Description
The utility model relates to a kind of high voltage electrostatic dust precipitator, belongs to technical field of electronic products.
In industrial production,, the quality and the next process of product do not brought adverse consequences if do not remove these dusts and static because the high pressure-temperature effect often makes and adhere to one deck dust on the product and have static.Want dedusting, must eliminate static earlier, therefore, electrostatic precipitation is a requisite operation, and is widely used in industries such as machinery, electronics, optics.At present, China mainly relies on imported product aspect electrostatic precipitation, and these imported product circuit structure complexity cost an arm and a leg, and its maximum shortcoming is these electrostatic precipitators once gone bad, and just all scraps, and can not keep in repair, and this product is not suitable for China's national situation.
The purpose of this utility model just is to provide a kind of circuit structure simple, and cost is low, and is easy to use, and has the high voltage electrostatic dust precipitator of maintenance characteristics.
For achieving the above object, the utility model can be realized by following scheme: the utility model is to be made of high-voltage power circuit and static neutralizer bar, and high-voltage power circuit is that the output at booster circuit is provided with the sampling rectification circuit and the power-supply fluctuation coefficient is carried out go to control after amplifying circuit is handled the overcurrent protection switch that is located on the booster circuit input through comparison circuit closed or disconnect; The static neutralizer bar is that the high-field electrode rod is housed in insulation tube, is provided with spray point on the high-field electrode rod, is provided with groove on insulation tube, and groove is embedded with the earthing pole steel wire, is provided with blast pipe quick connector and blowhole on insulation tube.
Blowhole on the insulation tube is corresponding with the spray point on the high-field electrode rod.
The utility model has the advantages that: high-voltage power circuit and static neutralizer bar are simple in structure, and cost is low, and is easy to use, and it is obvious to eliminate static and dust removing effects, can repeatedly keep in repair, and saves material.
The drawing explanation:
Accompanying drawing is the utility model overall structure schematic diagram.
Now the utility model is described in further detail in conjunction with specific embodiments:
The utility model is by high-voltage power circuit and static neutralizer bar two large divisions structure, and high-voltage power circuit is that the output at booster circuit (18) is in series with sampling rectification circuit (12) and the power-supply fluctuation coefficient is located at the closed of overcurrent protection switch K-3 on booster circuit (18) input through comparison circuit (14,16) and amplifying circuit (15) by relay K control or disconnects.The static neutralizer bar is that high-field electrode rod (7) is housed in insulation tube (6), on high-field electrode rod (7), be provided with spray point (4), one week of length direction at insulation tube (6) is provided with groove, groove is embedded with earthing pole steel wire (2), and on insulation tube (6), having blast pipe quick connector (3) and blowhole (5), blowhole (5) is that a round has interests to increase work efficiency.Operation principle of the present utility model is: high pressure output and the sampling resistor R1 in over-sampling rectification circuit (12) that the step-up transformer T2 in the booster circuit (18) has 7000V take out sampled signal, through halfwave rectifier diode D1, filter capacitor C1, E1 output dc voltage and with benchmark circuit (13) in reference voltage 5V acting in conjunction comparison circuit (16) in the input of comparator L2:A (LM393).When the output voltage in the sampling rectification circuit (12) was lower than reference voltage P1 (5V), comparator L2:A was output as low-voltage, and triode N2 ends, and no current passes through in the relay K line bag, and overcurrent protection switch K-3 is in closure state.The output of sampling rectification circuit (12) also be connected with the input of amplifier L1:A (LM358) in the amplifying circuit (15) and after voltage amplification with benchmark circuit (13) in resistance R 5, the comparator L2:B (LM393) in the R6 connecting place 12V voltage acting in conjunction comparison circuit (14), as 5 ends of comparator L2:B output 12V during greater than 6 ends, otherwise be output as zero.Therefore, alarm switch K-2 disconnects, and warning beacon lamp L3 is not luminous.When step-up transformer T2 output loop electric current is excessive; when the voltage of sampling rectification circuit (12) output is higher than by the reference voltage of P1 (5V) output; comparator L2:A output HIGH voltage; triode N2 conducting; relay K has electric current to pass through; overcurrent protection switch K-3 disconnects, and has protected whole factory high-tension circuit.Simultaneously, the K-1 closure of often making war, relay K continues to have electric current to pass through to guarantee to disconnect later on by step-up transformer T2, sends overload-alarm voltage by K-2.In addition, the output voltage of sampling rectification circuit (12) enters amplifying circuit (15), because T-3 disconnects, the output loop no current boosts, so amplifier L1:A output voltage is zero, the reference voltage in this voltage and the benchmark circuit (13) enters the input of the comparator L2:B in the comparison circuit (14) jointly, makes comparator L2:B be output as high voltage 12V, triode N1 conducting, zero load indication diode L3 is luminous to carry out zero load indication.Be parallel with capacitor C 2 at overcurrent protection switch K-3 two ends and piezo-resistance RV prevents the high pressure arcing, help overcurrent protection switch K-3 reliably working.Rectification circuit (17) is made up of step-down transformer T1 rectistack B1 (BRIDGE2) and three terminal regulator L4 (LM7812CT) and 12V is provided DC voltage for comparison circuit (14,16), amplifying circuit (15) and benchmark circuit (13).During use, blowing device is connected on the blast pipe quick connector (3) of insulation tube (6), open high-voltage power circuit, pass through high-voltage tip discharging, make air ionization, produce anion, under blowing effect, make negative ions and the neutralization of the charged ion on the product after these ionization reach static and the dust of eliminating on the product, result of use is fine.
