The utility model overcomes the deficiencies of a photoelectricity continuous type material level sensor and a sound wave continuous type material level sensor etc, allowing carrying on continuous material level measuring; moreover, the utility model is high in cost performance and easy to be expanded.
Description
The utility model relates to the Weight-balancing type level sensor.
The continuous coverage and the monitoring in real time of storage bin " material level " of field bitumen concrete mix equipment such as build the road will be used level sensor, in process of production, material is the sandstone compound about 200 ℃ in the feed bin, height from about 3 meters falls, in the hot aggregate bin is many, the rambling rugged surroundings of high temperature, dust, and building stones are very serious to the friction of level sensor.Continous way level sensors such as existing photoelectricity, ultrasound wave all can't be worked under this environment, and the measurement of material level for a long time affects the production run of bitumen concrete always.Present bitumen concrete mix equipment both domestic and external mostly uses the node type level sensor, and whether can only detect a certain position has material, can't measure actual material level in the feed bin.
The purpose of this utility model provides a kind of new Weight-balancing type level sensor, it is to have utilized the gravitational equilibrium principle dexterously, by leverage, the pressure that building stones in the storehouse are produced passes to pressure transducer, produce continuous measuring-signal (signal is handled by computer unit) by pressure sensor, thereby provide actual material level signal, the purpose of reach the material level continuous coverage, monitoring in real time; The utility model has overcome the deficiency of continous way level sensors such as existing photoelectricity, sound wave, successful solution this this difficult problem of kind equipment material level METHOD FOR CONTINUOUS DETERMINATION.
The utility model comprises that mainly bearing plate, bearing plate slip locating ring, pressure transmission pin, pressure transmission pin bearing groove, lever, sensor zero point set screw, pressure transducer and signal wire constitute.
The bearing plate below is provided with bearing plate slip locating ring, and bearing plate slip locating ring is installed on the lever sheath; The pressure transmission pin is fixed by pin-and-hole and bearing plate; One end on the lever left side has accepts the bearing groove that the pressure transmission pin transmits pressure; Right place is provided with the lever balance fulcrum shaft in the lever, and on the balance fulcrum pedestal of frame in being welded in the lever sheath, the lever fulcrum shaft locating sleeve is arranged on the fulcrum shaft; The pressure transducer that is connected with signal wire is installed in lever right-hand member top, and there is the pressure transducer carriage its below, and the set screw at zero point is installed in the top, and zero point, set screw was located on the sensor zero point set screw support that is connected on the lever sheath.The pressure transducer guard shield is laid in the pressure transducer outside of sensor lever right-hand member, is connected on the lever sheath.
The utility model is described in detail as follows with reference to Figure of description:
Fig. 1 is the utility model Weight-balancing type level sensor structural representation.
Fig. 2 is a lever balance fulcrum shaft synoptic diagram.
As shown in the figure:
1-bearing plate: carrying material pressure;
2-bearing plate slip locating ring: make bearing plate lower slider vertically, do not produce radial displacement, be welded on the lever sheath 7;
3-pressure transmission pin: transmit pressure to lever 5, fixing by pin-and-hole and bearing plate 1;
4-pressure transmission pin bearing groove: accept the pressure that pressure transmission pin 3 transmits, open on lever 5;
5-lever: transmit pressure;
6-lever balance fulcrum shaft: be balance pivot, and on the balance fulcrum pedestal of frame in being welded in the lever sheath;
7-lever sheath: protection lever assembly, fixedly bearing plate slip locating ring 2, sensor zero point set screw support 9 and pressure transducer guard shield 13;
8-sensor zero point set screw: regulate sensor zero point;
9-sensor zero point set screw support: sensor installation set screw at zero point 8 is welded on the lever sheath 7;
10-pressure transducer: pressure signal is converted to electric signal;
11-pressure sensor signal line:: transmit signal;
12-pressure transducer carriage: the setting pressure sensor is welded on the lever 5;
13-pressure transducer guard shield: the protection pressure transducer is connected on the lever sheath 7;
14-lever fulcrum shaft locating sleeve: prevent the axial wobble of lever.
The utility model is rational in infrastructure, sturdy and durable, reliability is high, be specially adapted to the level gauging work of abominable bitumen concrete mixing equipment of environment and ore, coal warehouse, improve measurement, the monitoring level of mal-condition blanking bin material level greatly, optimized production run.The past operating personnel can only guess by virtue of experience that the material level situation of each feed bin adjusts material loading, a storehouse flash often occurred, and material such as another storehouse cause the production run confusion, influence product, the quality of product.By using the balanced type level sensor, operating personnel can see the material level situation of each feed bin very intuitively, adjust the material loading amount in each storehouse in advance, guarantee the continuity of production, improve product, the quality of product, have improved production management level and labour productivity.This utility model ratio of performance to price height, be easy to promote, can be connected, can be connected with secondary instrument again, can be generalized to the building association area with computing machine.
