Description
Technical field
The utility model belongs to the industrial automation instrument field, especially a kind of level-sensing device that can be used in no clock furnace roof batch can.
Background technology
At present, along with development and national economy, material greatly abundant, material is also more and more, and the device and the instrument that are used to measure bin-level are also more and more exquisite, and precision, accuracy requirement are more and more higher.The method of level gauging is a lot, can use the level gage of different measuring principle at different operating modes and medium, and several level gauges commonly used such as air blast, static pressure type, float-ball type, Weight type, ultrasonic wave all have separately characteristics and range of application.
At present, the most widely used radar level-sensing device that is in no clock furnace roof batch can, the radargrammetry technology of radar level-sensing device uses advanced, with its good performance, stirring, temperature height are especially arranged in the groove jar, under the abominable measuring condition such as steam is big, corrosive medium by force, easily scabs, demonstrate its remarkable performance, in industrial production, bringing into play more and more important effect.Yet in the process of using the radar level-sensing device, the nitrogen consumption is too big, also needs frequent cleaning, and use cost is higher, and influenced by the nitrogen source of the gas, does not have nitrogen to use.
The utility model content
The technical problems to be solved in the utility model provides a kind of nitrogen that do not use, and is simple in structure, safeguard simply, and is mechanically operated batch can level-sensing device.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of batch can level-sensing device, it is characterized in that comprising windlass, and the below of described windlass freely is hung with weight, windlass drives by actuating unit, in a side of actuating unit counter is installed.
Said structure is described further, one side of described windlass, a side relative with actuating unit are provided with leading screw, described leading screw is connected with the central rotating shaft of windlass, and leading screw is provided with can be along the nut of leading screw axis slip, and the two ends of described leading screw are provided with near switch.Leading screw in the utility model is provided with the nut of slip, and whether what be used to detect weight arrives batch can bottom and top, monitors near realizing near switch that by nut the range of restriction weight prevents to damage the batch can inwall.
Said structure is described further, and described actuating unit is the low speed servo motor.The utility model is realized the lifting of weight by low speed servo driven by motor windlass, and the low speed servo motor can be controlled in two-way rotation, also can only control unidirectional rotation, is used to promote weight.
Said structure is described further, and the opening part of described windlass is provided with hollow mounting flange.Flange in the utility model under the windlass is used for fixedlying connected with batch can, and weight gos deep into batch can inside by the wire rope suspensioning of windlass, and other devices are located at outside the batch can, easy disassembly and maintenance.
Adopt the beneficial effect that technique scheme produced to be: the utility model drives the lifting that windlass is realized weight by actuating unit, and show the height of weight by counter, the cloth height that reflects material in the batch can, whether have material, avoided utilizing nitrogen use in the radar level-sensing device if utilizing mechanical drive mode to realize detecting batch can; By showing the sky of material in the batch can near switch and expiring, if do not have the emptying feed basin again to the batch can blowing, will form a pile material phenomenon in addition, batch can is piled upper sealing valve and can't be closed, and the material loading program is interrupted, the blast furnace stopping production.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Scheme of installation when Fig. 2 is the utility model use;
Wherein: 1, counter, 2, actuating unit, 3, windlass, 4, nut, 5, leading screw, 6, near switch, 7, weight, 8, level-sensing device, 9, batch can.
Embodiment
1 as can be known with reference to the accompanying drawings, and the utility model is specifically related to a kind of batch can level-sensing device, comprises windlass 3, counter 1, actuating unit 2 and rack gear arrangement, the below of windlass 3 freely is hung with weight 7, and windlass 3 drives by actuating unit 2, in a side of actuating unit 2 counter 1 is installed.One side of windlass 3, a side relative with actuating unit 2 are provided with leading screw 5, and leading screw 5 is connected with the central rotating shaft of windlass 3, and leading screw 5 is provided with the nut 4 that can slide along leading screw 5 axis, and the two ends of leading screw 5 are provided with near switch 6.
Actuating unit 2 is low speed servo motor or servomotor two-way, unidirectional rotation, and the low speed servo motor is realized the lifting of weight 7 by 3 rotations of electric motor driving windlass.Unidirectional rotating machine only needs weight 7 is mentioned, and relies on the gravity of weight itself to get final product during the whereabouts.
Fig. 2 is that level-sensing device 8 is installed on the scheme of installation on the batch can 9, and as can be seen from the figure, level-sensing device 8 is fixed in batch can 9 outer walls, weight 7 hangs by the steel wire of windlass 3, deeply, be used for the height of testing inner material, show by counter 1 to batch can 9 inside.
The utility model is used for the operation of blast furnace material distribution, wherein batch can is the middle-chain of blast furnace material distribution, the program of blast furnace material distribution is: with the material loading instrument material is moved in the furnace roof feed basin earlier, be put in the batch can after reaching some amount, after reaching the cloth condition in the stove, will expect that by throttling valve and lower seal valve, chute cloth is in stove.Reciprocation cycle.The level-sensing device major function is whether emptying of batch can when detecting blowing, if do not have the emptying feed basin again to the batch can blowing, will form a pile material phenomenon, and batch can is piled upper sealing valve and can't be closed, and the material loading program is interrupted, the blast furnace stopping production.Feed basin could continue to the batch can blowing after having only batch can emptying.
The utility model drives the lifting that windlass is realized weight by actuating unit, and the height of counter demonstration weight is arranged, and reflects the cloth height of material in the batch can, and whether utilize mechanical drive mode to realize detecting batch can has material; By showing the sky of material in the batch can near switch and expiring, if do not have the emptying feed basin again to the batch can blowing, will form a pile material phenomenon in addition, batch can is piled upper sealing valve and can't be closed, and the material loading program is interrupted, the blast furnace stopping production.
