Description
The utility model discloses the automatic survey sensor of a kind of gravity type material level multiple spot.It belongs to the Measuring and testing technical field.
At present, in the commercial production, the material level of storage or tank storage granular material exists a large amount of level gauging problems on detecting, and measures as the breeze material position of thermal power plant boiler Pulverized Coal Bin; The canned cement that petroleum drilling is used is measured or the like, though adopt some level measurement instruments,, even can not solve the level gauging problem well because of the complicacy of measuring situation is limited to separately, as: gravity point type (claiming suspension cone type again) and pressure type, can only decide a point measurement; Condenser type involves great expense again, and is subject to factor affecting such as measured medium temperature, humidity; Sound wave type, optical profile type are measured dynamic material and can not be solved again; The nuclear radiation formula is difficult to people and accepts because of technology, security reason; ,, then both consumed energy and occupied many locus when installing again if Weight type adds power though but the simple physical labor intensity of Weight type is too big.［ " level measurement instrument " China Machine Press (1978) ］.
According to investigations, in the industrial actual level gauging, also existing some has problem to be solved, as the measurement of thermal power plant boiler breeze material position, also adopts and manually pulls Weight type; The oilfield cement jar also knocks tank skin with instrument and estimates the cement material level.
The utility model purpose is: for solving the level gauging problem that exists in more above-mentioned commercial production, the utility model intends designing a kind of sensor that can utilize gravity to measure material level.Mainly can overcome Yin Wendu, humidity and different medium and change influence, and the gravity when utilizing solid accumulation is measured material level level gauging; Simultaneously can measure the material level of continuous variation; Can also solve in the process of material charging or discharging in feed bin the measuring-signal distortion that the material of disperse in the feed bin space causes; The lateral impact forces that also can overcome material irregular movement in feed bin is to the influence of sensor safety itself, stable, life-span and accuracy of measurement; And install, easy to maintenance, cost is low.
Be the technical measures that realize that the utility model is taked:
1) principle of work: when the powder in the feed bin sinks because of the action of gravity after piling up, its acting force is added on the light cone (2), drive light cone (2) and produce displacement downwards, cause light cone support (3) to move laterally, withstand electrode I (11), electrode I (11) is produced simultaneously move axially and contact, make circuit turn-on with electrode II (12).Demonstrating material level by the secondary Displaying Meter rises or the signal of buying securities with all one's capital; Powder reduces in feed bin, gravity when material level descends on the light cone (2) is eliminated thereupon, drag spring (5) drive person's light cone (2) and light cone support (3) return to original position, electrode I (11) disengages in the elastic force and the electrode II (12) of circuit spring (13), the secondary Displaying Meter demonstrates material level simultaneously and descends or the hole capital after selling all securities signal, to reach the purpose of monitoring whole process of production.
2) for can measure the material level of continuous variation, this sensor main body pipe (1) is designed to linearity, high together with feed bin approximately, in feed bin, vertically to install, main body pipe (1) divides some joints, by measurement requirement, some light cones (2) are housed, light cone support (3), electrode box (17) on every joint main body pipe (1), drag springs (5) etc. can detect the variation of some somes material levels.
3) open auger is buckled the tension force that (4) can regulate drag spring (5) according to the proportion of different material, play a kind of sensor and can measure the effect of various materials, sealing shell fragment (9) adopts withstand voltage folder Bu Dingji rubber or metal bellows, both can guarantee that electrode box was interior for to contact with extraneous material, and can guarantee the axial displacement of electrode I (11) again.
4) by main body pipe (1) electrode signal line (14) is drawn outside the storehouse and be connected with the secondary Displaying Meter, every joint main body pipe two ends are all sealed.
5) sensor main body pipe (1) can be made some joints, and its joint number and every joint length are decided according to the height and the measurement needs of feed bin.Connect in succession with the universal of easy accessibility between joint and the joint, in order to overcoming the lateral impact forces that the irregular movement of feed bin internal cause material causes, the stablizing of assurance sensor, safety and serviceable life, and installation, problem such as easy to maintenance.
Gravity type material level multimetering sensor construction (seeing accompanying drawing 1,2) is as follows:
(1) the main body pipe (1) of sensor is made of galvanizing pipe, can make some joints according to the height of feed bin; Every joint length is generally 1 meter, also can decide according to measuring needs.Adopt universal connecing (15) structure to link between joint and the joint,, guarantee stability, security and the serviceable life of sensor in order to overcome the lateral impact forces of dynamic material.
(2) light cone (2) props up slow-witted (3) with light cone and is connected with screw, and light cone support shaft (16) is housed on main body pipe (1), and light cone support (3) is contained on the axle (16), and it can do freely rotate around axle (16); The light cone vertex of a cone is connected with drag spring (5) with turnbuckle (4) with cable wire and is fixed on the main body pipe, like this, utilizes lever principle, and light cone (2) and support (3) thereof can become the gravity of material the transverse shift power of light cone support (3).
(3) electrode box of garden cylindricality (17) welds together with the main body pipe.Electrode box (17) structure is: electrode II (12) and electrode orienting sleeve (8) are equipped with in electrode cartridge receptacle (6) lining, and electrode orienting sleeve (8) act as fixed electorde spring (13) and guarantees that electrode I (11) moves axially the accuracy of direction; Electrode lid (7) act as and compresses sealing shell fragment (9); Sealing shell fragment (9) plays moving axially of sealing and assurance electrode I (11) and resets unaffected; Electrode spring (13) guarantees normally resetting by electrode II (12).
