Abstract
The utility model relates to a balance type lower-limit change level indicator which uses the law of motion of materials in material bins. The utility model works with the adoption of the comparison principle of a gravity balance. Inspection bands which are arranged at one end of the balance are suspended in a material bin, and the inspection bands are bent through the pushing force of materials in the material bin so that the balance loses balance. The balance situation of the balance can directly detect whether level in the material bin reaches the lower-limit. The utility model has the advantages of simple structure, no energy consumption, accurate detection, and convenient maintenance, being particularly suitable for lower-limit detection and control for the level of block-shaped material bins in metallurgy, mine, chemical engineering, and other factories and mines. The utility model has still more obvious effects of lower-limit detection and control for granular grain bins with raw grain or semifinished grain.
Description
The utility model relates to a kind of balance-type type lower limit level-sensing device, belongs to thing position measuring instrument.Factories and miness such as particularly suitable metallurgy, mine, chemical industry detect and control the lower limit of block bin-level.For raw grain or partly become the lower limit Detection ﹠ Controling of grain silo that more significant effect is arranged.This level-sensing device have the source of not consuming energy, equipment simple, detect accurately and characteristics such as long service life.
How the factories and miness of maximize, serialization being produced as blast furnace ironmaking, grain processing etc., need be provided with the granular storage of piece or provide feed bin, and the Detection ﹠ Controling of its material level often require very strict.The thing position measuring instrument of typing has electric pole type, blocking rotary type, condenser type, laser type, tuning-fork type and ultrasonic type etc. multiple at present, how the detecting element of these instrument need be contained on the inwall of feed bin, and be used for detecting the upper limit of feed bin, when the lumpiness of material, when weight is big, the impact failure phenomenon easily takes place, serviceable life is short, and must stop production during maintenance.
On the defeated blast furnace ironmaking production line of expecting of, belt higher in automatization level, be spherical or block raw material in its batching storage bin, this feed bin not only will be provided with the upper limit measuring instrument, also must be furnished with reliable lower limit Detection ﹠ Controling device simultaneously.Process stipulation: when filling with substance impacts the gate of feed bin bottom and prevents from material is broken into pieces in feed bin in order to avoid, and not quasi-full of the raw material emptying in the storehouse when the material charge level drops to certain altitude (lower limit), must stop blowing and feed supplement in feed bin in time.This just requires the lower limit of feed bin to detect promptly and accurately.In view of the above, the utility model proposes a kind of balance-type type lower limit level-sensing device, not only on effect, satisfied technological requirement, and simple structure, durable flexibly.
Balance-type type lower limit level-sensing device of the present utility model mainly is made up of support (1), detecting element (2), damping counterweight adjusting mechanism (3), vernier counterweight (4), main lever (5), the limiting bracket (6) that prevents to vibrate, detection band (7), caulking gum (8) and shell hood (9) etc. as shown in drawings.It is to utilize the characteristics of motion of material in the storehouse, the work of employing gravity balance comparison principle.This level-sensing device is installed in the top of feed bin, allows detect band (7) and vertically hang in the feeding port and the interlude of bulkhead in the feed bin, adjusts and detects the length of being with (7), makes the bottom of its underpart weight be in the lower limit of predetermined level.Adjust damping counterweight adjusting mechanism (3) and make balance be in equilibrium state, and in detecting element (2) fixed this moment with ing be " material is empty ", detecting element (2) sends the signal that need feed in raw material in feed bin.When balance to detecting the band inclination tiltedly and during out of trim, be considered as in the feed bin " have material empty ".When continuing to feed in raw material again behind the bottom that in hole capital after selling all securities, is dosed to detection band (7) bottom weight, at first bury weight, to detect band (7) by stockpile in the storehouse to the expansionary force of both sides again pushes away curved, to making the balance out of trim, thereby detecting element (2) just sends the signal of charge level more than lower limit to the operator.When discharge was to lower limit after material was full, it was exposed fully to detect band and weight, and balance restores balance again, and detecting element (2) sends " material is empty " signal once more, thus the purpose of the automatic Detection ﹠ Controling of realization feed bin lower limit.
Balance-type type lower limit level-sensing device of the present utility model owing to be installed in feed bin upper end, and has shell hood (9) limiting bracket (6) protection of preventing dust, prevent to vibrate; detecting element (2) is in the outside of feed bin in addition; so shock-resistant, vibration, long service life, repair and maintenance is convenient.
Claims (5)
1, a kind of by support (1), detecting element (2), damping counterweight adjusting mechanism (3), vernier counterweight (4), main lever (5), the limiting bracket (6) that prevents to vibrate, detect band (7), caulking gum (8), shell hood (9) waits the balance-type type lower limit level-sensing device of forming, it is characterized in that detecting formation one balance devices such as band (7) and vernier counterweight (4), support (1), main lever (5).
2, balance-type type lower limit level-sensing device according to claim 1 is characterized in that detecting band (7) termination, bottom and disposes a weight.
3, balance-type type lower limit level-sensing device according to claim 1 is characterized in that detecting element (2) places on the main lever (5), does not directly contact with material.
4, balance-type type lower limit level-sensing device according to claim 1 is characterized in that the level-sensing device body is installed in the top of feed bin, and allows detection band (7) vertically hang in feed bin feeding port bulkhead interlude.
5,, it is characterized in that detecting the degree of depth of being with (7) to hang in is the lower limit charge level place of feed bin according to claim 1 and the described balance-type type lower limit of claim 4 level-sensing device.
