The digital chest level gauge adopts the proximity switch as one sensor element, is based on the intelligent monitoring and diagnosing technology, and has the advantages of being simple in structure, low in cost, easy in repairing, resistant in disturbance and few in electric vulnerable part, which is suitable for being used for inspecting various gas cabinet piston motion parameter.
Description
[technical field]
The utility model relates to a kind of metallurgy industry coal gas level meter commonly used, relates in particular to a kind of digital level meter that is used for detecting all kinds of gas cabinet piston motion parameters based on Digital Technique.
[background technique]
Gas cabinet is the common main equipment of metallurgy industry.Under normal circumstances, it is used to store the coal gas that blast furnace, converter and coke oven produce in process of production, and when above-mentioned metallurgical furnace kiln blast wandering, gas cabinet discharges the coal gas of its storage, and that guarantees to produce normally carries out.In the gas cabinet air inlet with when giving vent to anger, accurately grasp movement velocity, move distance and the instant height of gas cabinet piston, of crucial importance to the gas cabinet safe operation, level meter is exactly the monitoring equipment that is used to detect all kinds of gas cabinet piston motion parameters, is the important accessory supporting with gas cabinet.
Level meter commonly used at present has polytypes such as radar level meter, optical fiber level meter.Radar level meter precision when normal the use is very high, is subject to surrounding environment and disturbs but exist, detect inaccurate, shortcomings such as poor stability.And radar level meter great majority are import equipment, and its core component is basically based on large-scale integrated circuit (LSI), easy-maintaining not after the damage.The optical fiber level meter is by optical fiber transducer, optical cable, photoelectricity change device and intelligent secondary meter is formed, detection resolution is 10mm, testing result accurately, stable, be not subject to disturb, but structural principle complexity, the fault point is more, behind fault row, cabinet position initial value must be appraised and decided at the scene by the professional workforce, and generally the technician without professional training can not detect, keep in repair, and can only change trouble unit.Above-mentioned two kinds of level meters investment all reaches more than 100,000 yuan, and the maintenance cost height, and service cycle is long.
[model utility content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of simple in structure, accurate stable and with low cost, digital level meter for ease of maintenaince of detection.
The technological scheme that the utility model adopted is: a kind of digital level meter, comprise upper saw pulley, take-up disk and balancing weight, the take-up disk by be fixed together, concentric deep bid and shallow bid form, and be installed on the base by rotatingshaft, the one end links to each other with the gas cabinet piston with conductor rope on being wrapped in deep bid by upper saw pulley, the other end links to each other with balancing weight by the conductor rope that is wrapped on the shallow bid, big rim circumference evenly offers notch, be equipped with near switch on the base on the opposite of notch, this links by transmission line and industrial control computer near switch.
Described adjacent be 1.5 times of notch distance near the mounting distance between the switch.
Described notch is a square opening.
The beneficial effects of the utility model are: produce the rectangle square signal near switch as primary sensing element change in location owing to notch when the take-up disk rotates, handling the back by PLC central processing unit (CPU) (CPU) is exported by display device, in entire work process, no analog signal transmission, be not subject to disturb, electric easily worn part is few; When mechanism broke down, operator can judge the level meter fault point rapidly by the PLC display picture, and easy to maintenance, maintenance cost is low; Its mechanical transmission is partly simple in structure, with low cost, for ease of maintenaince.After fault was got rid of, operator only need pass through computation, can appraise and decide cabinet position initial value.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a take-up disk of the present utility model and near the mounting structure schematic representation of switch.
Among the figure: 1-gas cabinet, 2-piston, 3-conductor rope, 4-upper saw pulley, 5-take-up disk, 6-balancing weight, 7-rotatingshaft, 8-base, 9-notch, 10-be near switch, 11-deep bid, 12-shallow bid.
[embodiment]
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1 and Fig. 2, a kind of digital level meter, comprise upper saw pulley 4, take-up disk 5 and balancing weight 6, take-up disk 5 is by being fixed together, concentric deep bid 11 and shallow bid 12 are formed, and be installed on the base 8 by rotatingshaft 7, the one end links to each other with piston 2 in the gas cabinet 1 with conductor rope 3 on being wrapped in deep bid 11 by upper saw pulley 4, the other end links to each other with balancing weight 6 by the conductor rope 3 that is wrapped on the shallow bid 12, balancing weight 6 is in order to equalizing piston 2 gravity, deep bid 12 evenly offers notch 9 along circumference, this notch 9 is a square opening, on the base 8 on the opposite of notch 9, be equipped with two near switch 10, two is 1.5 times of notch 9 pitch-rows near the mounting distance between the switch 10, and this links by transmission line and industrial control computer near switch 10.
Mechanical transmission by upper saw pulley 4 and conductor rope 3, the straight line motion up and down reciprocatingly of gas cabinet 1 inner carrier 2 is converted to forward and reverse rotation motion of take-up disk 5 correspondences, owing to be fixedly mounted on the base 8 of take-up disk 5 near switch 10, not with 5 motions of take-up disk, the rectangle square signal that when take-up disk 5 rotates, is produced near switch 10, be directly inputted to PLC through transmission line and by the DI interface, after CPU handles, by upper display device output.
Claims (3)
