The level sensor outer bottom has fastening bolt (8), level sensor bottom to be contained in the sliding recess on the sensor stand (9), is fastened on the sensor stand (9) by fastening bolt (8).
Cover on the storage tank vertical cylinder (13) is installed, cylinder piston rod is in storage tank, the cylinder piston rod lower end connects copper and scrapes piece (14), copper is scraped piece (14) and just is attached on the inwall of storage tank, and it is the position of a plurality of level sensors on the storage tank outer wall of the relative position of the up and down track of storage tank inwall that copper is scraped piece (14).
Magnetic conduction powder feed jar material level indicating alarm device comprises material level pilot lamp and alarm of a plurality of level sensors, similar number.A plurality of material level inductors are fixed on the feed tank outer wall by the groove type sensor stand.Regulate bolt by elastic force spring force is finely tuned, and prevent that jar interior powder is adsorbed on the feed tank inwall by the permanent magnetism post and can't falls.And promote copper by the cylinder that the storage tank loam cake is installed with certain thrust and scrape piece, will in time be struck off by the material powder that level sensor is adsorbed on the storage tank inwall.The material level pilot lamp is installed in the place that the production equipment switch board is easy to observe.The pressure switch of level sensor is connected with warning circuit with indicator light circuit by lead, thereby control material level pilot lamp is lighted and extinguished, and control alarm.
Compared with prior art, the utlity model has following beneficial effect:
1. the level sensor of this material level indicating alarm device comes the controlled pressure switch by the magnetic force of magnetic conduction powder and permanent magnet and the elastic force of elastic spring.When material level was higher than sensor, magnetic force was during greater than elastic force, the pressure switch closure; On the contrary, when material level was lower than inductor, elastic force was greater than magnetic force, and pressure switch disconnects.The bin level indicator of this structure has improved the reliability of material level indication greatly, can adapt to the environment of working site fully.
2. the level sensor of below adopts two pressure switches, often opens for one, and one normally closed.The pilot lamp of the below of normally closed pressure switch control indicator light circuit; Often open pressure switch control warning circuit.So.This device not only can be indicated material level, also has the effect of warning, has increased the security of operation.
3. do not need the situation of artificial observation material level, avoided the simple work that repeats of workman, reduced working strength of workers, improved work efficiency, reduced cost.
