Background technology
Cottrell is to receive the device of catching dust in the flue gas with the electrostatic depuration method, is the ideal equipment of purified industrial waste gas.Its purification work mainly relies on discharge electrode and these two systems of receiving electrode to finish.When importing high voltage direct current between two electrodes, produce the yin, yang ion at electrode space, and act on exhaust gas particles surface by electrostatic field, it is moved to its opposite polarity electrode under the effect of electric field force, and be deposited on the electrode, reach the purpose of gathering dust.Two electrode systems all have rapping apparatus, and when beater periodically beat two-pole device, the dust that sticks was thereon shaken off, and fall into the bottom ash bucket outside ash exhauster is discharged body.The waste gas that has been cleaned is then entered in the atmosphere through chimney by outlet, thereby finishes the purification process of flue gas.
At present, the rapping apparatus of cottrell is divided into anode and negative electrode employing electromagnetic hammer top rapping device or adopts reducing motor side direction transmission sidepiece rapping apparatus.Adopt electromagnetic hammer top combination rapping apparatus, have the cost height, quantity is many, and problems such as difficulty are installed, use, keep in repair relatively.Adopt reducing motor side direction transmission sidepiece combination rapping apparatus, it is inhomogeneous then to exist vibration acceleration to transmit, and defectives such as cross shear are arranged.If reach same ash-removal effect, just need to strengthen the weight of beater, thus, power consumption was increased, cause the increasing of cross shear again, also cause the cathode and anode frame deformation easily; Simultaneously, because the influence that system expands with heat and contract with cold, beater is difficult to align the centre of percussion of vibrating rod, and the stressed effect of vibrating rod is poor, has influence on the dust collection effect and the service life of equipment; In addition, adopt the cottrell of reducing motor side direction transmission sidepiece rapping apparatus, it is big that the cottrell of its volume ratio same size is wanted, cost height not only, and take between the electric field and electric field and import and export loudspeaker between the space also bigger.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provide a kind of simple in structure, reliable, cost is low, the cottrell top of long service life combination rapping apparatus.
Its technical scheme is: a kind of cottrell top combination rapping apparatus, comprise the anode crossbeam, the cathode line back timber, by reducing motor, power transmission shaft, the anode rapping apparatus that vibrating rod and beater constitute, by reducing motor, power transmission shaft, the cathode rapping device that vibrating rod and beater constitute, it is characterized in that: be set in parallel in that fixed interval has a plurality of bearings on the power transmission shaft in the anode rapping apparatus of anode crossbeam top, be fixed with galianconism on the bearing respectively, the other end of galianconism is the rod hinge connection by bearing pin and beater respectively, be fixed with on the anode crossbeam and the vertical corresponding vibrating rod of beater, reducing motor is connected with power transmission shaft; Be set in parallel in that fixed interval has a plurality of bearings on the power transmission shaft in the cathode rapping device of cathode line back timber top, be fixed with galianconism on the bearing respectively, the other end of galianconism is the rod hinge connection by bearing pin and beater respectively, be fixed with on the cathode line back timber and the vertical corresponding vibrating rod of beater, reducing motor is connected with the power transmission shaft insulation by the porcelain insulator in the incubator.
Above-mentioned anode rapping apparatus is installed in the penthouse of the outer anode system of electric field top, and its reducing motor is installed on the side wall outside of electric cleaner penthouse.
Reducing motor in the above-mentioned cathode rapping device and incubator are installed on the outside of electric cleaner side wall.
Above-mentioned anode rapping apparatus and cathode rapping device are respectively equipped with many row's multilayers at the top of electric cleaner.
Its technique effect is: cottrell of the present utility model top combination rapping apparatus, because the cathode and anode rapping is the side direction transmission, and top rapping, so: 1. acceleration profile more rationally, does not evenly have cross shear, and internal fault is few, and component's life is long; 2. under identical efficiency of dust collection, energy efficient more; 3. cathode and anode adopts the sagging mode of hanging oneself, and suppresses hot extensional effectively; 4. the relation that relative position can not expand with heat and contract with cold because of system between vibrating rod and the beater and being affected, and can not change the stressed effect of vibrating rod.5. transmission device all is installed at the electric field top, the anode rapping apparatus is arranged at the penthouse interior (being called the upper strata rapping) of the outer anode system of electric field top, the cathode rapping device is arranged at electric field inner cathode line back timber top (being called lower floor's rapping), thereby has eliminated in the shared big problem in space of electric cleaner electric field front and back end layout rapping apparatus; 6, adopt the rappings of many row's multilayers, realized rapping power transmission efficiency height, deashing property is good, simple in structure, fault rate is low, reduce the purpose of electric cleaner equipment volume and investment.
