Description
Technical field
The present invention is a kind of steel belt type self-calibration weight dropper charge level indicator, belongs to the automatic measurement field, is specifically related to the level gauging meter of powdery in the feed bin, granular solids thing.Be mainly used in the measurement of industry bin-levels such as fuel-burning power plant, cement, chemical industry, food.
Technical background
At present, the device or the instrument that are used to measure bin-level are of a great variety, and precision, accuracy are had nothing in common with each other.Along with the raising of development and national economy and automatization level, more and more higher to precision, the accuracy requirement of level gauging.The existing Plumb-bob Material Level Meter that is used for measuring powdery, graininess and blocks of solid material, all adopt traditional wire rope to drive the lifting of weight as carrier, and by electronically to wire rope in feed bin rising or the length of decline measure, calculate corresponding material level.Its complex structure, cost height, maintenance are big.Because intermittent continuous operation, repeatedly winding and the release of wire rope on the level-sensing device internal cylinder, cause the wire rope distortion serious, cause weightlessness/commutation detector switch slow movement or malfunctioning, the disorder cable fault often occurs, thereby greatly reduce the reliability of Plumb-bob Material Level Meter work and the stability of operation.Some Plumb-bob Material Level Meter must be installed on the top of feed bin because of its intrinsic mechanical property.After each measurement was finished, a small amount of granular material or the dust that carry in the slit on wire rope surface just can inevitably be brought into box house, formed the continuous accumulation of dust.Finally cause weightlessness/commutation detector switch malfunctioning, the result is that to have caused wire rope be not that to fail to lay down be exactly can not draw up, and motor rotation blockage takes place, bury hammer, falls to hammer into shape phenomenon, can't normally use.If untimely cleaning easily causes the damage of level-sensing device, but safeguard very difficulty.Owing to motor rotation blockage produces overheatedly, there is the hidden danger of breaking out of fire, dust explosion, the safe and stable operation that influence is produced.The traditional hand-rail type weight dropper charge level indicator that generally uses in thermal power plant can be worked under serious dust condition, but use inconvenience, actual measured amount and data remote in the time of can't carrying out material level by manually being operated.
Summary of the invention
The objective of the invention is to: a kind of steel belt type self-calibration weight dropper charge level indicator and measuring method are provided.It is a kind of architectural characteristic of utilizing ordinary tape measure, replaces wire rope, utilizes the relative motion between the band-wheel and replace the level-sensing device that conventional weightlessness/commutation detector switch and mechanism, principle contactless, that the application tape measure is found range are carried out demarcation certainly, can be worked under mal-condition with steel band.Its physical construction is simple, possesses automatic/hand/artificial three kinds of metering systems.Wide accommodation, actual measured amount and data remote in the time of can carrying out material level.Even the resistance of in-site measurement hammer weight or rope changes, do not need on-the-spot the adjustment yet, just can reliably working.
The present invention constitutes like this: an end of wire rope (2) connects measures hammer (1), the other end is connected with an end of rope band connector (4) after walking around two fixed pulleys (3) again, the other end of rope band connector (4) is connected with the end that one side is printed on the steel band (5) of linear scale, steel band (5) other end is walked around counting sampling wheel (6), fix and be wound on the wheeled steel (7), wheeled steel (7) is enclosed within clutch axle sleeve (9) and goes up and fix by jump ring (23), the clutch handle (8) that positioning bead (24) and retainer spring (25) are housed is installed on a side of wheeled steel (7), with the fulcrum is axle, can snap in the end of the clutch axle sleeve (9) that has pilot hole (26), monophase machine (10) with reducing gear is fixed on the carrier base (11), and clutch axle sleeve (9) is installed on the output shaft of monophase machine (10) by key-groove mode.The damping wheel (12) that is supported by dampening bracket (13) is pressed on the steel band (5); dampening bracket (13) is a fulcrum with the damping axle (14) that is installed on the carrier base (11); damping torsion spring (15) is housed on the damping axle (14) simultaneously; one end of damping torsion spring (15) is stuck on the dampening bracket (13); the other end is fixed on the carrier base (11); one end be equipped with the counting Vane wheel (17) counting wheel shaft (16) pass carrier base (11) and by bearing fixing on carrier base (11); the other end links to each other with counting sampling wheel (6); position detecting switch (18) places the top of counting sampling wheel (6); be fixed on the carrier base (11); between position detecting switch (18) and counting sampling wheel (6), dust swabbing pig (19) is installed; the intelligent controller (20) of interior dress wiring board (27) covers counting Vane wheel (17); and be fixed on the carrier base (11); one side of carrier base (11) is equipped with protective cover (21), the maximum height of the corresponding bin-level of maximum sign numerical value of steel band (5) high scale chi.
The present invention is compared with prior art: it is rational in infrastructure, installs simply, easy to maintenance, has automatic/hand/artificial three kinds of metering systems, can the oneself demarcate.The infield flexible and selectable effectively prevents the suction of dust, the upper-lower position of correct response weight in feed bin, and level gauging is accurate, precision is high.Fundamentally stopped to bury hammer, fallen hammer, the generation of disorder cable, motor rotation blockage and superheating phenomenon, under the situation of environment very severe, also can guarantee the measurement of carrying out bin-level reliably and with long-term.
