Electrostatic precipitator is divided into vertical, horizontal two big classes, the horizontal fly-ash separator of the many employings of large-scale electrostatic precipitator.
Deashing mechanism many employings vibration dust-cleaning mode of horizontal fly-ash separator cathode and anode, there is reentrainment of dust problem cannot solve, and greatly affects the purification efficiency of electric precipitator. Mobile polar plate electrostatic precipitation device can efficiently solve reentrainment of dust problem, and efficiency of dust collection is significantly improved. But, the pole plate of mobile polar plate electric dust collector moves up and down along with sprocket rotation on upper and lower two axles, owing to there is a large amount of dust and corrosive gases in fly-ash separator inside, Working environment extreme difference, cannot examination and maintenance when fly-ash separator runs, causing pole plate, chain stuck sometimes, sprocket wheel such as cannot rotate at the fault.
Current mobile polar plate electric dust collector is once there are the situations such as movement pole plate, driving chain are stuck, bearing damage, motor can not stop in time, inner guide frame, wire brush, chain will be caused, a large amount of damages of the parts such as bearing support, owing to electric precipitator internal electric field is high-voltage and high subnormal ambient, on-bne repair cannot be carried out so that the high voltage supply system of whole electric field all to be stopped transport, cause fly-ash separator almost complete failure.
For the problems referred to above, it is necessary to a kind of safety protection device for chain wheel of exploitation, to solve the problems of the technologies described above.
Practical novel content
The purpose of this utility model is exactly a kind of safety protection device for chain wheel developed for Problems existing in mobile polar plate electric dust collector actual production; when mobile pole plate, driving chain are stuck; safeguard protection device action; pole plate axle is made to stop rotating; thus play the provide protection to equipment; avoid a large amount of damages of the parts such as both inner pad, save maintenance cost.
For achieving the above object, the utility model adopts following scheme:
A kind of mobile polar plate electric dust collector safety protection device for chain wheel; it comprises drive sprocket, drive sprocket seat; driven sprocket wheel, driven chain wheel seat; spacing cover, bearing support, pole plate axle and key; the swinging moment of step-down gear is transferred on drive sprocket by drive sprocket seat; again through the driven sprocket rotation of chain-driving, and drive driven chain wheel seat that pole plate axle is rotated, it is characterised in that driving and driven sprocket wheel connects driving and driven chain pulley seat respectively by some shearing pins.
Described drive sprocket empty set is on drive sprocket seat, and drive sprocket is connected on drive sprocket seat by shearing pin, and the swinging moment of step-down gear is transferred on drive sprocket by drive sprocket seat.
Described driven sprocket wheel is connected on driven chain wheel seat by shearing pin, and the interior hole of driven sprocket wheel is provided with inner sleeve empty set on pole plate axle, and driven chain wheel seat is connected with pole plate axle by key.
In technique scheme:
Driving and driven sprocket wheel can arrange shearing pin simultaneously and connect driving and driven chain pulley seat respectively, and the program is provided with two cover shearing pins, all can carry out safeguard protection on driving and driven sprocket wheel; Shearing pin can also be set on drive sprocket and connect drive sprocket seat, by bolt-connection driven chain wheel seat on driven sprocket wheel; Or shearing pin connection driven chain wheel seat is set on driven sprocket wheel, by bolt-connection drive sprocket seat on drive sprocket; The connecting mode of above-mentioned three kinds of shearing pins can be implemented according to specific needs respectively.
Drive sprocket empty set is on drive sprocket seat, and can dally on drive sprocket seat, is provided with the spacing cover of drive sprocket and can prevent drive sprocket from axially altering on drive sprocket seat; In driven sprocket wheel, the inner sleeve empty set on hole is on pole plate axle, and can dally on pole plate axle, and driven chain wheel seat is connected with pole plate axle by key, is provided with spacing cover and prevents driven chain wheel shaft to altering on pole plate axle; The swinging moment of step-down gear is transferred to drive sprocket by drive sprocket seat, and by chain gear to driven sprocket wheel, rotary motion is passed on pole plate axle by driven sprocket wheel by driven chain wheel seat, and band movable plate electrode axle rotates.
Shearing pin is circumferentially arranged on driving and driven sprocket wheel and driving and driven chain pulley seat, and its quantity, material and specification are determined according to demand.
If pole plate drives and designs a set of safeguard protection device on the motor-driven driving and driven sprocket wheel that slows down, drive sprocket seat is connected by shearing pin by drive sprocket, driven chain wheel seat is by the driven sprocket wheel of bolt-connection, deceleration motor by shearing pin by power transmission on drive sprocket, again through the driven sprocket rotation of chain-driving, and band movable plate electrode axle rotates; When mobile pole plate motion is broken down, now driving chain is stuck, shear pin breakage, and drive sprocket seat dallies in the interior hole of drive sprocket, drive sprocket stall, and driven sprocket wheel also all stops rotating thereupon.
The beneficial effects of the utility model are: when mobile pole plate motion is broken down, can cutting off fault transmission system in time, available protecting moves the core components such as pole plate, avoid a large amount of damage of inner parts and fly-ash separator of serious failure, steady running efficiency; It is convenient to failture evacuation, saves maintenance cost simultaneously.
Below in conjunction with drawings and Examples, the utility model is illustrated further.
