Detailed description of the invention
Composition graphs 1, Fig. 2, illustrate a kind of automatic cleaning apparatus for electrostatic precipitation case of the present utility model.Multiple collecting plate 15 and corona discharge electrode 16 are vertically installed in electrostatic precipitation case, automatic cleaning apparatus comprises two scrapers 11 in two the control of dust faces being horizontally set on each collecting plate 15 respectively, the both sides of collecting plate 15 are stretched out at the two ends of scraper 11 respectively, the two ends of scraper 11 respectively level are fixed with the driving mechanism two doctor blade holders, 10, two doctor blade holders 10 are fixed with for driving it to move up and down.
Wherein, driving mechanism comprises four driving chains 9 being separately fixed at two doctor blade holder 10 two ends, and the top of every bar driving chain 9 is connected with a driven sprocket 14, and its underpart is connected with a drive sprocket 8; The left internal side of dust-removing box 1 and the top of right inside side respectively level are fixed with the fixed axis 12 of about two groups correspondences and supporting clutch shaft bearing 13 thereof, clutch shaft bearing 13 are set with corresponding driven sprocket 14; The left internal side of dust-removing box 1 and the bottom of right inside side respectively level are fixed with the second bearing 7 of about two groups correspondences, in second bearing 7 of about two groups correspondences, correspondence is set with two active rotating shafts 6, and the two ends correspondence of each active rotating shaft 6 fixes two drive sprockets 8; Two active rotating shafts 6 stretch out the right flank of dust-removing box 1 respectively, the external part of two active rotating shafts 6 is fixed with two drive sprockets 5 respectively, the right outside side of dust-removing box 1 is fixed with motor 2, be fixed with correspondence between two drive sprockets, 3, two drive sprockets 3 and two drive sprockets 5 of correspondence successively before and after on the output shaft of motor 2 and be connected with two chain drive-belts 4.
Driving mechanism also can adopt and install electric pushrod on dust-removing box 1, and the push rod of electric pushrod is fixedly connected with doctor blade holder, uses the flexible drive doctor blade holder 10 of push rod in electric pushrod to move up and down.
Wherein, the cross section of scraper 11 is the prism of approximate U shape, and the seamed edge of its opening part is set to blade respectively, as shown in Figure 3, and the control of dust face of both sides blade laminating collecting plate 15.
