Description
One, technical field:
The present invention relates to the level-sensing device of industrial dedusting device ash storehouse level gauging and control, particularly a kind of temperature-resistant and pressure-resistant sealing mechanical oscillating resistant level gage.
Two, background technology:
Be still a difficult problem in the environmental protection fly-ash separator of industries such as iron and steel, electric power, cement such as electric precipitator, the grey storehouse of sack cleaner, the measurement of hopper material level, because of material in its storehouse is the very little powder of granularity, its density is little, specific inductive capacity is very little, easily fly upward, temperature is higher in the storehouse, generally, have negative pressure (the band malleation that 70Kpa), also has in the storehouse greater than 180 ℃, and pressure transient brings certain difficulty therefore for the measurement of grey storehouse, hopper material level.Handy when the machinery resistance of using is at present revolved or hinder the formula level-sensing device of moving and just loaded onto, but bad because of the sealing performance, can not adapt to higher temperature and have pressure working environment, dust in very short time, just enter level-sensing device spool in, and cause stall, corrupted.Therefore, be badly in need of research and be applied in handy mechanical level-sensing device on the fly-ash separator ash storehouse.
Three, summary of the invention:
Revolve or hinder for solving above-mentioned existing machinery resistance that to move formula level-sensing device sealing performance bad, incompatibility higher temperature and the pressure working environment arranged, the technological deficiency of easy corrupted, the invention provides a kind of temperature-resistant and pressure-resistant sealing mechanical oscillating resistant level gage, mainly constitute by watch shell, detection swing arm assembly, eccentric wheel assembly, drive motor assembly, measuring oscillating bar, gauge outfit heatsink flange, seal assembly, measurement baffle-wall and instrument protective.Drive motor in the drive motor assembly, detection arm decide shaft seat and rotating shaft is fixed on the watch shell by erecting frame; The detection swing arm assembly that is made of detection arm, detection springs, contact and microswitch is installed in detection arm to be decided in shaft seat and the rotating shaft; The eccentric wheel assembly that is made of eccentric wheel, excentric shaft and excentric shaft roller is installed on the drive motor main shaft; Measuring oscillating bar is installed on the seal assembly, passes the gauge outfit heatsink flange again, and an end is equipped with roller, and roller is located between detection arm, and end is equipped with the measurement baffle-wall in addition; Flange-cooled side of gauge outfit heatsink flange and watch shell join, and sealing shroud and the instrument protective in side and the seal assembly joined in addition; Seal assembly is made of sealing shroud, elastic equilibrium support chip, heatproof sealing gasket and axle envelope convoluted diaphragm, elastic equilibrium support chip one end as withstand voltage balancing component is installed on the measuring oscillating bar by the leaf spring seat of honour, and end is fixed on the sealing shroud by following of leaf spring in addition; Be installed in the joint of two sections of measuring oscillating bar as the axle envelope convoluted diaphragm of sealing fulcrum by mesopore, and sealing hard with it, the diaphragm periphery is installed on the sealing shroud; Between sealing shroud and axle envelope convoluted diaphragm, the heatproof sealing gasket is housed.
Principle of work: the present invention is installed in the working site, and detection arm is under the drive motor eccentric wheel assembly drives, and deciding rotating shaft with detection arm is the center swing, stirs the measuring oscillating bar directional swing.When tested material not during the contact measurement baffle-wall, the moment shell balance of the detection springs on the detection arm and axle envelope convoluted diaphragm and elastic equilibrium support chip, detection arm is not opened, and microswitch is not touched in the contact, does not send material level and reports to the police and control signal; When tested material contact measurement baffle-wall, measuring oscillating bar stops swinging in the position of being obstructed.At this moment, drive motor drives eccentric wheel and still does eccentric rotation, and excentric shaft and excentric shaft roller are stretched the detection springs on the detection arm, and detection arm is opened, and the microswitch conversion is touched in the contact on other head of detection arm, sends and reports to the police and control signal.
Owing to take technique scheme, beneficial effect of the present invention is: utilize axle envelope convoluted diaphragm to be the withstand voltage element of balance for sealing fulcrum, elastic equilibrium support chip, above two kinds of instrument elements are referred in the level gauging first use, the sealing of mechanical type level-sensing device, anti-positive and negative work pressure and working temperature problem have been solved, this level-sensing device be applicable to malleation≤0.25Mpa, negative pressure≤-100Kpa, temperature≤400 ℃, the grey storehouse that the less dust of density is bigger, the measurement of hopper material level, can be widely used in industries such as iron and steel, electric power, cement.
