Abstract

The utility model relates to a vibrating ceramic-shaft crack signal generating device for electric dust collectors. A main body is cylindrical. A driving clamping disk is in a cylindrical staircase shape. A small end of the driving clamping disk is connected with an input shaft and is fixed by a cylindrical pin. Three jaws of a big end plane are equispaced and a through hole is arranged. A driven clamping disk is similar to the driving clamping disk. A small end of the driven clamping disk is connected with an output shaft key. A through hole of the driven clamping disk is arranged on the end surface of the jaws. After an output shaft is provided with a bearing, the output shaft is arranged in the driving clamping disk and is orderly arranged in a check ring, a gasket, a torsional spring, a flat key and the driven clamping disk. Both ends of the torsional spring are embedded into fixing grooves of the driving clamping disk and the driven clamping disk and endow the torsional spring with proper preloaded torsion. The rated moment of the torsional spring is smaller than the resistance moment of a vibrating system. An upper and a lower covers are axial cylindrical casings. A screen cap is used for fixing a probe seat and a hollow bolt. A photosensitive element and a light source are installed on the corresponding probe seat. An electric wire is led in from the hollow bolt. When a ceramic shaft is broken, under the action of the torsional spring, clamping claws restore to original positions. Two through holes are mutually communicated. Light rays irradiate the photosensitive element through the through holes. A control circuit obtains a triggering signal to act, and the vibrating system automatically stop to give an alarm.

Description

Electric cleaner vibrating ceramic-shaft crack signal generating means

Affiliated technical field

The utility model relates to a kind of electric cleaner vibrating ceramic-shaft crack signal generating means.

Background technology

Electric cleaner adopts the inner rapping form of electric field more, and its power is imported into by the outside, and the electric cleaner voltage of electric field is very high, and the porcelain axle is to intercept the high-tension critical component of electric field in the power transmission chain, is arranged on the electric cleaner inboard.It is a kind of most common failure that the porcelain axle breaks, the cause more complicated, and it is all multifactor to relate to machinery, operating mode and porcelain axle sole mass.At present, still there are not vibrating ceramic-shaft crack signal generating means and similar products in the known electric cleaner, therefore breaking of porcelain axle often can not in time be found, but along with dust stratification progressive additive in the electric field, efficiency of dust collection descends, can change according to electric index indirectly, the fume emission quality reduces, and symptoms such as chimney over-emitting black exhaust, the obvious minimizing of the defeated ash amount in grey storehouse are judged.Although also be provided with porcelain axle safety plate on the electric cleaner that has, be intended to protect the porcelain axle, the fault-free warning function.Wanting dynamically to grasp vibrated system ruuning situation, only depend on patrolling and examining of operating personnel, by rule of thumb, obviously is not all right with inferring.

Summary of the invention

In order to solve the problem that the porcelain axle breaks and lags behind and know, the utility model provides a kind of electric cleaner vibrating ceramic-shaft crack signal generating means, this device and photoelectric control circuit and main circuit organically combine, form an energy instantaneous transmission alarm signal when the porcelain axle breaks, cut off the automatic operation control system of the optical, mechanical and electronic integration of electrical source of power.

The utility model be achieved in that it by flat key, probe socket, driven chuck, go up cover, screen cap, hollow bolt, straight pin, power shaft, initiatively chuck, bearing, back-up ring, packing ring, torsion spring, cover, output shaft etc. are formed down.It is cylindric that apparatus main body is, and two ends are respectively power shaft and output shaft; Initiatively the chuck cylinder is stepped, and endoporus is many ledge structures, and small end is connected with power shaft, and fixes with straight pin, and three-jaw is uniform on the same circumference of transverse plane greatly, is provided with a through hole apart from arc places such as pawl center line and pawl are wide on the circumference.Driven chuck shape is to initiatively chuck is similar, and small end is connected with the output axle key, holds three-jaw to be distributed on the same circumference greatly, and a through hole is located at the intersection of circumference and pawl end face center line.With bearing fixing on output shaft, the initiatively big end of chuck of packing into together then, pack in turn again back-up ring, packing ring, torsion spring, flat key and driven chuck; The two ends of torsion spring embed respectively in the holddown groove of active chuck and driven chuck, and give torsion spring suitable prefastening torque.Under the normal condition, the torsion spring rated moment is less than the vibrated system moment of resistance, and the device two ends produce angular displacement, and two through hole misplaces.When the porcelain axle breaks,, for device, the rapping moment of resistance disappears, and two groups of claws set back relatively under the effect of torsion spring prefastening torque, and two through hole is in line.Last cover is the cylindrical case of branch in axial with following cover, and structure is basic identical, and probe socket is symmetrically distributed, and firmly is connected with last cover, following cover by the screen cap, and hollow bolt is screwed in the probe socket, and with the bolt connection, following cover is fixed on the support between two cases.Light-sensitive element in the photoelectric control circuit and light source are installed on the corresponding probe socket, connect electric wire and introduce from hollow bolt.

The beneficial effects of the utility model are, in conjunction with other means dynamic monitoring vibrated system ruuning situation, and the immediate feedback porcelain axle information that breaks, autostop is reported to the police.
