Abstract
The present invention discloses an insulation shaft insulation box of an electrostatic precipitator. According to the present invention, the insulation shaft insulation box is connected with an electrostatic precipitating box; a rotation shaft insulator is arranged inside the insulation shaft insulation box; one end of the rotation shaft insulator is connected with a motor drive shaft, the other end of the rotation shaft insulator is connected with a vibration and beating shaft; the insulation shaft insulation box further comprises an air duct arranged on the insulation shaft insulation box; the air duct is communicated with an inner chamber of the electrostatic precipitating box by the insulation shaft insulation box. With the present invention, hot air is blown to the low end surface of the contacting position of a conical insulation casing and the electrostatic precipitating box by the air duct to form an air curtain, and is blown to the surrounding of the vibration and beating shaft to form an air curtain, the air curtains and a quartz plate for supporting the vibration and beating shaft collectively provide a shielding effect; the pressure of the air curtain is slightly higher than the pressure of the process gas, such that the process gas can not invade the support insulator insulation box and the insulation shaft insulation box, the surface of the insulator can not be contaminated, the normal operation of the system is not affected, the balance of the gas pressure of the production system is not damaged so as to always protect the smooth production.
Description
Technical field
The present invention relates to a kind of electric cleaner, is a kind of electric cleaner insulation axle insulated case specifically.
Background technology
Electric cleaner is to utilize high voltage electric field to separate the equipment of higher suspension dust in gas.Send a negative electrode very of high pressure, dust collector pole ground connection, the dust that will be adsorbed on the electrode through rapping shakes, and from ash bucket, discharges.Dedusting both at home and abroad connects the electric cleaner fault that the personage generally acknowledges has three, and one is the cathode line breaking releasing, causes anode and cathode to be communicated with and send and do not power on; The 2nd, the beater mouth falls down and falls into ash bucket and block ash exhauster; The 3rd, the cathode support insulator is polluted, failure of insulation and can't send high-tension electricity.Replace the fine wire lead that negative electrode is not broken with the rigid female polar curve, can not fall hammer with whole hammer replacement burst hammer, and failure of insulation takes place the most easily, the most difficult again thoroughly solution.Insulated connecting piece in the cathode rapping mechanism is to transmit moment of torsion, selects the insulation axle for use.During the electric cleaner operation, the surface of insulator all contacts with process gas, if condensations such as the steam in the process gas, acid are adhered on the insulator; Its surface insulation promptly lost efficacy, and formed surface leakage, and electric field send and do not power on when serious; The heat of electric leakage burns out insulator and breaks or rupture; Some particle also can cause insulation breakdown attached to insulator surface in the process gas, and traditional processing method is labor cleaning or blowing cleaning, fails to tackle the problem at its root.
Summary of the invention
In order to solve deficiency of the prior art, the invention provides a kind of simple in structurely, compact, the rotating shaft insulator surface is pollution-free, a kind of electric cleaner insulation axle insulated case that electric cleaner is stable.
The technical scheme that the present invention adopts is: a kind of electric cleaner insulation axle insulated case; The support and connection of insulation axle insulated case are on the electric precipitation case; Be provided with the rotating shaft insulator in the insulation axle insulated case, rotating shaft insulator one end connects motor driving shaft, and the other end connects rapping shaft; It is characterized in that also comprising the airduct of being located on the insulation axle insulated case, airduct is communicated with the electric precipitation box cavity through insulation axle insulated case inner chamber.
Said rapping shaft is supported between insulation axle insulated case and electric precipitation case through quartz plate, and airduct is communicated with the electric precipitation box cavity through insulation axle insulated case, quartz plate successively.
Said airduct is communicated with insulation axle insulated case inner chamber through jet pipe.
30-60 ° of said jet pipe and rotating shaft insulator angle.
Insulation axle insulated case outer end, left side and reductor link, and are driven by motor-driven beam warp rotating shaft insulator and stretch into the rapping shaft in the electric precipitation case.Airduct blows to insulation axle insulated case and electric precipitation case junction through jet pipe with hot blast, around rapping shaft, forms air curtain, plays shielding action jointly with the quartz plate that supports rapping shaft, and the process gas in the electric precipitation case is kept off outside insulation axle insulated case.Rapping shaft rotates during operation, and the air curtain around the moving link does not hinder the motion of member, has played protective effect simultaneously again.Airduct and jet pipe are installed in the middle part of insulated case.The angle that jet pipe inserts insulated case is 40～50 °, nozzle hole diameter 2～3mm, wind regime pressure 3000～3500Pa.
The present invention adopts the contaminated structure of avoiding insulating; On supporting insulator insulated case and insulation axle insulated case, install airduct additional; Blow to lower surface that the taper insulating sleeve contacts with the electric precipitation case to hot blast from certain angle and form air curtain and blow to the quartz plate shielding action jointly that forms air curtain and supporting rapping shaft around the rapping shaft, the pressure of a little higher than process gas of pressure of air curtain makes process gas can not invade a supporting insulator insulated case and an insulation axle insulated case; Insulator surface just can not polluted; Can fundamentally eliminate insulator and occur because of contaminated situation about destroying, it is minimum finally to sneak into the shared ratio of air curtain wind in the process gas, does not influence the normal operation of system; Can not destroy the balance of production system gas pressure, can protect the steady of production all the time.
