Composite dust collecting board static dust collecting device of air purifier
The utility model relates to a kind of electrostatic dust-collecting device of air staticizer.
The electrostatic dust-collecting device of present air purifier, not to have that windage is big, noise is high, chargeability is low, dust-collecting area is little, dust removal efficiency is low, the life-span is short, cleaning is inconvenient, be exactly only to use metallic plate as dust collection plate, this dust collection plate gather dust reach a certain amount of after, charged dust just is difficult to deposition, influence dust collection effect, especially bigger to particle diameter dust, very easily in air-flow, produce secondary fly-up, reduce clean-up effect, so, keep good dust removal efficiency for this dust collection plate, just must regularly clean, this is trouble.In addition, with a centre that is installed in air funnel of discharging, inconvenience will increase man-hour, increases production cost.
The electrostatic dust-collecting device that provides a kind of dust containing capacity big is provided the purpose of this utility model, has simultaneously that internal resistance is little, noise is low, chargeability is high, convenient for production.
The purpose of this utility model is achieved in that in the insulation frame of electrostatic dust-collecting device and constitutes passage by compound dust collection plate insertion, insert the discharge reel again in passage.Being provided with of reel of discharge can be to be parallel to compound dust collection plate.Compound dust collection plate is made up of battery lead plate, grid frame, porous member, and porous member is located both sides in battery lead plate through grid frame.The discharge reel is made up of framework, discharge silk, extension spring, and discharge thread is with after extension spring is connected, and two ends are fixed on the framework and are tightened up.Can fix the discharge silk more than 1 or 1 on each framework.
Passage of the present utility model is to be inserted in the insulation frame by compound dust collection plate to constitute, and windage is little, noise is low so have.Compound dust collection plate skin is a porous member, and the dust that is captured, smoke particles will be deposited in the hole of porous member, and its specific area is more much bigger than metallic plate, thereby has improved its dust containing capacity widely, thereby has prolonged the time limit of continuous use.The suitable discharge silk of contaminated air direction flows through the high-voltage electrostatic field of passage, long flow path, chargeability height, dust removal efficiency height.Owing to adopted plug-in type, therefore have convenient for productionly, when cleaning, only need compound dust collection plate is taken out, can clean airing to porous member, regeneration is used, and also can change new porous member easily.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a cutaway view of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the front elevation of compound dust collection plate;
Fig. 4 is a kind of structure chart of discharge reel.
With reference to Fig. 1, Fig. 2, in the frame 2 that insulate, be inserted with compound dust collection plate 5 and discharge reel 4 at intervals, equidistant mutually, and parallel, the passage of compound dust collection plate 5 and insulation frame 2 formation cuboids, discharge reel 4 is in the middle of the passage, and insulate with insulation frame 2.Compound dust collection plate 5 joins with the negative pole of DC high-voltage power supply, and discharge reel 4 joins with the positive pole of DC high-voltage power supply, thereby forms the high-voltage electrostatic field between compound dust collection plate 5 and discharge reel 4.Compound dust collection plate 5 is made up of battery lead plate 7, grid frame 9, porous member 6, and porous member 6 is located in the both sides of battery lead plate 7 through grid frame 9, can pack into easily grid frame 9 and therefrom taking out of battery lead plate 7 and porous member 6.Planar shaped can be made in the surface of compound dust collection plate 5, also can make curved surface shaped, as Fig. 1, shown in Figure 3.Discharge reel 4 is made up of framework 8, discharge silk 3, extension spring 1, discharge threads 3 be fixed on the framework 8 after extension spring 1 is connected, can fix the discharge silk 3 more than 1 or 1 on each framework 8, as Fig. 1, shown in Figure 4.
Operation principle: when discharge reel 4 and compound dust collection plate 5 are connected the positive and negative electrode of DC high-voltage power supply respectively, promptly form a high-voltage electrostatic field between them, when band dust air therefrom passes through, very easily by charged, the particulate that makes positively charged is to compound dust collection plate 5 motions, and electronegative particulate is captured by compound dust collection plate 5 and discharge silk 3 at last to 4 motions of discharge reel, the positive electricity particle deposition is in the hole of porous member 6, and the negative electricity particle deposition is on discharge silk 3.Because of porous member 6 has very big storage dirt space, thus very big dust containing capacity is arranged, thus prolonged air purifier continuous service time greatly, reduced the clean and maintenance number of times.
