The structure comprises a cylindrical side-shaking and beating box arranged on a side surface of the casing of the electrostatic precipitator, a transmission shaft provided with a vibrating strike hammer and coaxially arranged in the cylindrical side-shaking and beating box, and a power device arranged outside the cylindrical side-shaking and beating box and capable of driving the transmission shaft to rotate, wherein, the transmission shaft comprises a transmission shaft with the high voltage electricity and the vibrating strike hammer and an insulation transmission shaft; the transmission shaft with the high voltage electricity and the vibrating strike hammer is connected with the power device through the insulation transmission shaft connected with the transmission shaft with the high voltage; and dust removing blades are arranged in the cylindrical side-shaking and beating box and driven by the transmission shaft. Compared with the prior art, the invention has the advantages that extra power consumption is unnecessary and the dust-removing effect is good.
Description
Technical field:
The present invention relates to a kind of dust arrester.
Background technology:
Existing electric cleaner all is provided with cathode ash-clearing structure, cathode ash-clearing structure, mainly be divided into two kinds of frame modes of top rapping and side arm sinker, in the middle of the top rapping frame mode because of the restriction of its rapping dynamics, the ash-removal effect of electric cleaner negative electrode is failed ideal, and the side arm sinker frame mode can be controlled freely because of its rapping dynamics, the rapping dynamics can be bigger, structure is simple relatively, and is easy to maintenance, used on a large scale in the electric precipitation industry.
As shown in Figure 2, the operation principle of side arm sinker frame mode is: by power set 5, make power transmission shaft 4 rotations, drive the cathode assembly of beater 3 bump electric cleaner inside 7, dust stratification in the parts is fallen in the flue-dust retainer, kept the cleaning and the discharging function of negative electrode normal.Wherein, the effect of transmission insulator 4b is the band high-tension electricity parts and outside grounded parts (reductor) short circuit of isolated electric cleaner inside.The effect of side rapping case 2 is sealing transmission insulator 4b, it is not contacted with air outside, make insulator can not cause the insulator conduction because of contacting with the cold air of outside and producing surface sweating, and the integral sealing of assurance electric cleaner, not producing leaks out has influence on dust removing effects.But in use, because the bottom of dust deposit in the rapping case of deduster inside, be stacked into the parts place of the band high-tension electricity in the case then, high pressure (40,000 volts～100,000 volts) is directly by dust stratification and casing short circuit always, thereby makes the electric cleaner inefficacy.
In order to address the above problem, people have designed two kinds of following technology:
1. installing air curtain winding-up in case additional manages in the case and jets, prevent that dust enters in the rapping case in the electric precipitation, its shortcoming is need the air of jetting in case be heated, make its temperature be higher than dew-point temperature, prevent to cross the low insulator surface dewfall that causes and cause short circuit because of entering air in the case, therefore, its energy consumption very big (will increase winding-up blower fan and electric heater unit).
2. the bottom of rapping case is changed into downward-slopingly, make dust stratification in the case write the flue-dust retainer of electric cleaner voluntarily.
Its shortcoming is: limited by the housing of electric precipitation, its bottom gradient can not be very big, and it is undesirable that it unloaded grey effect when gradient was not enough.Simultaneously since the dust of electric precipitation inside charged after, its adhesion greatly increases, after particularly Dang Zhong fine dust sticks to boxboard, can not come off voluntarily (unless carrying out the mechanical type rapping), dust is stacked into the high voltage component place gradually, causes short circuit.
Goal of the invention:
The object of the present invention is to provide a kind of cathode ash-clearing structure that need not the electric cleaner additive decrementation electric energy, that ash-removal effect is good.
The present invention realizes like this, comprise the cylindrical shape side rapping case that is arranged on electric precipitation housing side, the power transmission shaft that has beater in cylindrical shape side rapping case of being coaxially set, be arranged on the power set that the drive power transmission shaft outside the cylindrical shape side rapping case rotates, power transmission shaft is made of the power transmission shaft and the insulation power transmission shaft of band high-tension electricity, the power transmission shaft that has the band high-tension electricity of beater is connected with power set by connected insulation power transmission shaft, be provided with the dedusting blade in cylindrical shape side rapping case, the dedusting blade is driven by power transmission shaft.When the electric precipitation negative electrode carried out rapping, the rotation that links simultaneously of this dedusting blade was scraped and is fallen adhering to, accumulate in dust on the cylindrical shape side rapping chamber interior wall, prevents that dust is stacked into the high voltage component place gradually, causes short circuit.
For cylindrical shape side rapping case is kept clean, the dedusting blade is the spiral vane along the axis spiral.Like this, under the transmission of the spiral vane that rotates, the dust that enters in the cylindrical shape side rapping case is sent to outside the cylindrical shape side rapping case.
The present invention compared with the prior art owing to adopted the dedusting blade in cylindrical shape side rapping case, therefore, having need not the advantage additive decrementation electric energy, that ash-removal effect is good.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of prior art.
The specific embodiment:
Now in conjunction with the accompanying drawings and embodiments the present invention is described in further detail:
As shown in the figure, the present invention includes the cylindrical shape side rapping case 2 that is arranged on electric precipitation housing 1 side, the power transmission shaft that has beater 34 in cylindrical shape side rapping case 2 of being coaxially set, be arranged on the power set 5 that the drive power transmission shaft 4 outside the cylindrical shape side rapping case 2 rotates, power transmission shaft 4 is made of the power transmission shaft 4a and the insulation power transmission shaft 4b of band high-tension electricity, the power transmission shaft 4a that has the band high-tension electricity of beater 3 is connected with power set 5 by connected insulation power transmission shaft 4b, be provided with dedusting blade 6 in cylindrical shape side rapping case 2, dedusting blade 6 is driven by power transmission shaft 4.Dedusting blade 6 is the spiral vanes along the axis spiral.
