Abstract
The utility model discloses a lifting assembly of a device for measuring the residual carbon amount of flash ash. The lifting assembly comprises an ash receiving ejector rod, a burning ejector rod and an ash discharging ejector rod which are arranged on a lifting plate; the lifting plate is arranged on a moving block in threaded connection with a screw rod; one end of the screw rod is connected with an output shaft of a lifting motor; the other end of the screw rod is fixed on a support seat; and a No.1 photoelectric switch, a No.2 photoelectric switch, a No.3 photoelectric switch and a No.4 photoelectric switch are arranged on the support seat. Through adopting the lifting assembly, lifting motions of the ash receiving ejector rod, the burning ejector rod and the ash discharging ejector rod can be realized through the single shaft driving; and the lifting assembly has the advantages of stability in motion and high position precision; the noise and blockage can be avoided; and the reliability of the measuring device is ensured.
Description
Technical field
The utility model relates to a kind of lifting assembly based on flying dust carbon residue content measurement device in the heat power plant boiler ash discharge flue of weightless technology.
Background technology
Flying dust carbon residue content is the important indicator of reflection fuel-burning power plant coal-burning boiler burning efficiency in the heat power plant boiler flue, detects the flying dust remaining carbon in real time and will help instructing boiler operatiopn, correctly adjusts coal-air ratio, improves combustion control level; Rationally the index of control flying dust remaining carbon helps reducing cost of electricity-generating, improves the economy of unit operation.
The boiler flue flying dust remaining carbon pick-up unit that domestic power plant comes into operation at present all is to adopt Microwave Measurement Technique to measure remaining carbon in the flying dust basically, but Microwave Measurement Technique is subjected to influence that coal changes greatly to the measuring accuracy of flying dust remaining carbon, after in case the coal of boiler combustion changes, the measuring accuracy of remaining carbon just cannot be guaranteed, even the variation tendency of the measured value of remaining carbon and actual remaining carbon is all inconsistent.And the present situation of present domestic coal in power plant the variation of coal is bigger exactly.
Flying dust remaining carbon measurement mechanism based on weightless technology has the advantage that measuring accuracy height, measuring accuracy are not subjected to the influence of coal variation.This device comprises the sampling unit of drawing ash sample, the measuring unit of measuring carbon content in the ash sample and the control module of measuring unit.Measuring unit comprises receives grey assembly, calcination assembly, ash discharge assembly, transposition assembly, lifting assembly, weigh assembly and electric component, by electrical control, a series of repetitive cycling operations such as measuring unit is received ash, calcination, weighed, ash discharge and blowback are finished the surveying work to the flying dust residual carbon content.Lifting assembly will be received grey push rod, calcination push rod and ash discharge push rod and send to the required specified altitude assignment of each station.
In production operation process in the past, receive grey push rod, calcination push rod and ash discharge push rod and drive the realization elevating movement by multiaxis, this structure exist push rod motion inadequately steadily, positional precision is low, noise is big, easily stuck shortcoming, influence the normal operation of pick-up unit, testing result is impacted.
Summary of the invention
Goal of the invention: in order to solve the problems of the technologies described above, the utility model provides a kind of lifting assembly of flying dust carbon residue content measurement device, and the push rod motion steadily, positional precision is high, noise is little, no stuck phenomenon.
Technical scheme: a kind of lifting assembly of flying dust remaining carbon measurement mechanism comprises the receipts ash push rod, calcination push rod and the ash discharge push rod that are arranged on the lifter plate; Lifter plate is arranged on the movable block, and movable block is connected with threads of lead screw; Leading screw one end is connected with the output shaft of lifting motor, and the other end is fixed on the bearing; Bearing is provided with an optoelectronic switch that all is electrically connected with lifting motor, No. two optoelectronic switches, No. three optoelectronic switches and No. four optoelectronic switches.
Wherein, be provided with the through hole that linear bearing is installed on described lifter plate, the axis of guide passes linear bearing, and axis of guide two ends are fixed on the bearing.
Beneficial effect: the lifting assembly of flying dust remaining carbon measurement mechanism of the present utility model drives by single shaft and realizes receiving grey push rod, calcination push rod and the elevating movement of ash discharge push rod, motion is steady, high, the noiselessness of positional precision, no stuck phenomenon guarantees the measurement mechanism reliability of operation.
