Abstract
The invention discloses an electric dust collector which comprises a shell and at least one movable positive pole dust collecting device arranged inside the shell. The movable positive pole dust collecting device comprises dust collecting positive poles distributed in a loop mode, and a drive mechanism used for driving the dust collecting positive poles to move along the loop. The drive mechanism comprises a driving rotary shaft, a driven rotary shaft and a power source, wherein the driving rotary shaft and the driven rotary shaft are in pivot connection with the shell, and the power source drives the driving rotary shaft to rotate. The dust collecting positive poles are of a flexible belt-shaped structure tensioned by the driving rotary shaft and the driven rotary shaft. Due to the characteristic of power transmission of a belt transmission mechanism, drive power of the power source is converted into friction force between contact surfaces of the dust collecting positive poles and the driving rotary shaft so as to drive the dust collecting positive poles to move along the loop. Obviously, compared with the prior art, the electric dust collector has the advantages of simplifying the structure remarkably and then lowering the manufacturing cost. In addition, according to practical application, when the equivalent dust collecting efficiency is achieved, the weight of rolled steel consumed by the dust collecting positive poles is about 12.5% of that consumed in the prior art, and accordingly the overall manufacturing cost is further lowered.

Journey, and there is axial limiting function to the anode 2 that gathers dust, can prevent from gathering dust anode 2 along along loop moving process along rotating shaft axially
Play, thus functional reliability and the safety of electric cleaner can be improved.For the ease of understanding the concrete structure of active rotating shaft,
Please also refer to Fig. 7, the figure shows the structural representation of active rotating shaft shown in Fig. 6.
As it was previously stated, the anode 2 that gathers dust in this programme gather dust face and air flow direction is vertically arranged, in order to be able to make after removing dust
Air-flow is quickly timely discharged by air vent 112, multiple anode 2 interval settings successively of gathering dust in this programme.Through practical application
In the set point of spacing value statistics is shown, when the value of spacing value is in the range of 100mm-150mm, ensureing dedusting effect
On the basis of fruit, air-flow can be made quickly timely to be discharged by this interval.Analysis shows further, the electricity when spacing value is for 125mm
Cleaner unit dust removing effects are optimal.
Additionally, in view of gather dust anode 2 frictional force effect under with active rotating shaft 31 synchronous axial system, in order to extend the anode that gathers dust
2 service life, the anode 2 that gathers dust in this programme is made up of high-wearing feature material, specially 65 manganese steel belt or stainless steel band system
Become.Certainly, meet active rotating shaft 31, drive gather dust anode 2 with its rotating in same direction on the basis of, gather dust in this programme anode 2
Also can be made using other wear-resistant materials.
Further, as shown in figure 5, the housing 1 in this programme includes housing body 11 and symmetrical is fixed on housing master
Two auxiliary shells 12 of body 11 lateral wall；Wherein, air inlet 111 and air vent 112 are opened in housing body 11, active rotating shaft
31 and driven spindle 3 be located in two auxiliary shells 12 respectively, and be provided with dust cleaning brush 4 in each auxiliary shell 12, with clear
Sweep the face of gathering dust of the anode 2 that gathers dust.Obviously, by tensioning is gathered dust the active rotating shaft 31 of anode 2 and driven spindle 32 in this programme
Be articulated in air current flow separate from auxiliary shell 12 in it is achieved that dust catching area (flow area) outside to the anode that gathers dust
2 dedusting, thus avoiding reentrainment of dust in dust catching area, improves the efficiency of dust collection of electric cleaner.
It should be noted that the quantity of dust cleaning brush 4 depends on power and the practical structures of electric cleaner, meeting dedusting effect
On the basis of fruit, in this programme, also only can set this dust cleaning brush in an auxiliary shell 12.
Furthermore, it is necessary to explanation, for the ease of understanding the overall structure of electronic precipitator, in this programme in the accompanying drawings only
Illustrate partly to gather dust anode 2, and the particular number of the anode that gathers dust is related to the overall structure of electric cleaner and efficiency of dust collection, therefore,
Anode 2 particular number of gathering dust constituting mobile anode dust arrester does not limit protection scope of the present invention.
The foregoing is only the preferred embodiment of the present invention, do not constitute limiting the scope of the present invention.Any
Any modification, equivalent and improvement of being made within the spirit and principles in the present invention etc., should be included in the power of the present invention
Within the scope of profit is claimed.
