Traditional negative electrode small frame cathode line is only by being bolted on fixed head 3 and the connecting plate 4, but do not have sparking electrode in the coupling part, forms the discharge blind area, makes the dusty gas by this part can not carry out charged effectively.Generally have tens even a hundreds of negative electrode small frame in an electric cleaner, if adopt above-mentioned form negative electrode small frame will form large tracts of land discharge blind area, this greatly reduces the operating efficiency of electric cleaner.
The utility model content
The utility model is proposed in order to address the above problem, its purpose is to provide a kind of negative electrode small frame that is used for electric cleaner, in this negative electrode small frame, junction at every cathode line and fixed head and connecting plate is provided with the enhancing tooth, to prevent in the negative electrode small frame, the forming discharge blind area, make the dust in the electric cleaner fully charged, thereby improve the operating efficiency of electric cleaner.
In order to achieve the above object, the utility model provides a kind of negative electrode small frame that is used for electric cleaner, and this negative electrode small frame comprises framework, cathode line, fixed head, connecting plate, enhancing tooth and bolt.Cathode line is installed on fixed head and the connecting plate, when being separately fixed at the two ends up and down of cathode line on fixed head and the connecting plate with bolt, add the enhancing tooth in the junction of cathode line and fixed head and connecting plate, strengthening tooth is welded by steel plate and discharge plume, can be according to the kind of selected cathode line, use different enhancing teeth, the effect that strengthens tooth is identical with general cathode line, on small frame, connect high voltage direct current, thereby when making all cathode line obtain the high pressure discharge, the use that strengthens tooth prevents from the discharge blind area to occur in the junction of framework and cathode line, can more fully carry out chargedly, effectively utilize the space thus, make electric-field intensity distribution even dusty gas, both save the energy, improved the operating efficiency of deduster again.
Compare with traditional negative electrode small frame, negative electrode small frame of the present utility model is owing to structural change has outstanding advantage, promptly improved the charged area of cathode line, eliminated the discharge blind area of negative electrode small frame, region of discharge is more evenly distributed, and exhaust gas dust is charged more abundant in the electric cleaner, effectively utilizes the space, save the energy and power, improved the operating efficiency of dedusting.In addition, identical according to the employed enhancing tooth of negative electrode small frame of the present utility model with traditional cathodic discharge polar curve, do not need to set up new production process, cost is not too big variation also, installs also very easy.
