Description
Technical field
The present invention relates to a kind of weight material position machine.
Background technology
Weight dropper charge level indicator is mainly used in measuring the height of materials in feed bin and various storage tanks, user is reliably grasped material
Material position in storehouse, can be used to measure the material position of various complex environment feed bins, including powdery, the medium such as graininess and lump material,
It is widely used in chemical industry, food is metallurgical, water power, cement, plastics, mining and other industrial circles.
Existing weight dropper charge level indicator is made up of the coupled weight material-height exploring actuator two parts of measure and control instrument.
Its operation principle is that weight material-height exploring actuator is placed on silo roof, and weight is put into storehouse by motor by rope traction, is surveyed
Control instrument control detection actuator self-timing is detected to material position, and when measuring every time, weight is since silo roof original position
Decline, encounter charge level and be back to the measurement of silo roof wait next time immediately.Measure and control instrument passes through to the down or up process of weight
Signal transacting can obtain silo roof to the distance of charge level, then subtract with the high height in storehouse the height of measurement to obtain the height of material position
Degree, measure and control instrument shows controlling level.Because weight dropper charge level indicator often works in the environment of dust, its sealing is poor, easily mill
Damage, measurement height value error is big, using occurring burying the abnormal conditions such as hammer, disconnected hammer often, so as to cause the problem of motor is damaged.Mesh
