The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, the traveling electrode deduster of a kind of capable of regulating dust cleaning brush of the utility model, comprises outer case of dust remover (1), stationary electric field (2), and mobile electric field (3), the dust cleaning brush (4) of mobile electric field is located on moving shaft holder (5).Can adjust easily the relative distance of dust cleaning brush (4) and mobile electrode plate (6) by the adjustment of moving shaft holder position, stop because the wearing and tearing of dust cleaning brush bristle cause having space between dust cleaning brush and mobile electrode plate, thereby guarantee ash-removal effect.
As shown in Figure 2, moving shaft holder (5) is provided with slide rail (7) or chute (8), upper corresponding chute (8) or the slide rail (7) of being provided with of base substrate (9), and slide rail (7) and chute (8) be moving cooperation each other.The setting of slide rail and chute, it is convenient to make to adjust.
As shown in Figure 2, the slide rail (7) of the preferred dovetail shape of the present embodiment and the chute (8) of swallow-tail form, be a matching relationship each other.Dovetail structure is with respect to general rectangle slideway, and many effects of a location, only allow moving shaft holder move along the direction of slide rail, can make slideway and associated mechanisms arrange succinctly, and moving shaft holder work are more reliable.
As shown in Fig. 2, Fig. 1, originally the base substrate (9) that is implemented in moving shaft holder is provided with link supports seat (10), connecting rod (11) is connected with moving shaft holder (5) through link supports seat (10), the upper cover of connecting rod (11) has spring (12), one end withstands on moving shaft holder, and one end withstands on link supports seat (10).Dust cleaning brush is selected roll-type dust cleaning brush, and its axle is arranged in moving shaft holder.When original state is installed, cause deashing unclean in order not make to leave space between brush silk and moving anode plate, dust cleaning brush is compressed and is attached on mobile electrode plate, now brush silk is bent.Because brush silk is that stainless steel is made, now mobile electrode plate is brushed with certain pressure to deashing, and dust cleaning brush converts this pressure to the thrust acting on moving shaft holder by axle; When original state is installed, the spring withstanding on moving shaft holder is compressed, and spring has a thrust to bearing block, and this thrust and dust cleaning brush keep balance to the thrust of bearing block.When after the wearing and tearing of dust cleaning brush brush silk, the space between dust cleaning brush and mobile electrode plate is strengthened, and pressure reduces, moving shaft holder stress balance is broken, under the effect of spring thrust, bearing block drives dust cleaning brush to move to the direction of being close to mobile electrode plate, until reach a new balance.In the situation that dust cleaning brush weares and teares, the thrust of spring makes moving shaft holder drive dust cleaning brush automatically to adjust to and be close on traveling electrode Board position all the time, keeps dust cleaning brush deashing clean.
As shown in Figure 2, Figure 4 shows, shown in Fig. 5, every two dust cleaning brushs (4) correspondence is arranged in ash bucket, be close to the two sides through mobile electrode plate (6) herein, staggered being arranged in parallel of moving shaft holder (5) of supporting dust cleaning brush (4), the bearing (14) in moving shaft holder (5) is to be arranged in prejudicially on bearing block.The present embodiment is by moving shaft holder (5) interlaced arrangement, make it to slide along slide rail (7) is staggered, avoid two adjacent moving shaft holders (5) mutually to support in the time sliding and affect dust cleaning brush (4) with the mobile space of moving shaft holder (5), having strengthened the shift motion of dust cleaning brush axle (13) along slide rail (7) direction; The bearing (14) that supports dust cleaning brush is arranged on moving shaft holder (5) edge prejudicially, can avoid dust cleaning brush axle (13) to support prematurely on another moving shaft holder (5), further strengthen the shift motion of dust cleaning brush axle (13) along slide rail direction, make dust cleaning brush (4) in wearing and tearing, dust cleaning brush axle (13) can slide to mobile electrode plate (6) automatically along with moving shaft holder (5), thereby extend the replacing time of dust cleaning brush (4), kept the clean of mobile electrode plate (6).
This enforcement moving shaft holder inner bearing (14) adopts self-aligning bearing.When wearing and tearing, dust cleaning brush (4) easily causes axle (13) and bearing (14) decentraction when inhomogeneous, bearing damage, adopts self-aligning bearing, because its roller raceway is spheric, the angular displacement that can adapt between two raceway axial lines has angular movement, effectively prevents bearing damage.
The above; it is only preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction, any simple modification, equivalent variations that every foundation technical spirit of the present utility model is done above embodiment, all fall among protection domain of the present utility model.
