Abstract
The utility model relates to a detecting device which is suitable for a blast furnace charging level with 2000 m<3> or more than 2000 m<3>; the detecting device mainly solves the disadvantages of the prior art in a special condition, for example, gauge rod stopping happens, and the phenomenon that the gauge rod is lifted before reaching the charging level, therefore, the detecting value can not reflect practical condition. The measures for solving the disadvantages are that: the novel blast furnace detecting device is mainly composed of a charging level gauge rod 1, a hoist 2 connected with the charging level gauge rod 1, a motor 3 connected with the hoist 2, and a computer 5 connected with the motor 3 by a lead wire 4; a signal processing card 6 is connected between the motor 3 and the computer 5 by the lead wire 4. The detecting result is reliable for really reflecting the real charging level detected by the blast furnace gauge rod, the process requirements are completely met, and the structure is simple and the device is easily implemented.
Description
Technical field
The utility model relates to measuring apparatus, more is applicable to the means of detection of 2000 cubic metres of volumes and above blast furnace material level.
Background technology
Blast furnace furnace roof stock rod is one of blast furnace key equipment, is the most important reference point that the blast furnace operating personnel monitor and operate blast furnace, and its observed value should accurately reflect the height of State of Blast Furnace liftout position.Because blast furnace production is an airtight production environment, the rhythm that blast furnace is produced is controlled, regulated to the real time data that the test set that the control of production process must rely on each position of blast furnace to install detects, and wherein the blast furnace probing rod signal directly reflects the situation and the degree of depth that blast furnace top raw material cloth distributes.Because the blast furnace internal-response changes soon, environment is abominable, complex working condition is very big to the influence that detects, so existing detection method is as Special Circumstances, as in stock rod test process if the slide calliper rule phenomenon, stock rod is just carried chi etc. when the stock rod no show material level in advance, its detected value then can't truly reflect practical situation.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and handles by carrying out distinctive signal, can accurately detect the situation of stock rod to material level, makes the blast furnace probing rod signal reflect the novel blast-furnace charge level detector of the situation of roof material distributing more realistically.
Realize the technical measures of above-mentioned purpose:
The novel blast-furnace charge level detector, mainly the computer that is connected with motor by material level stock rod, the windlass that is connected with the material level stock rod, the motor that is connected with windlass, by lead is formed, and it is: be connected signal processing card by lead between motor and computer.
It is: time module and signal processing module are housed in the signal processing card.
The utility model detected result is reliable, can reflect truly that promptly the blast furnace probing rod test detects actual material level state, satisfies processing requirement fully, and simple in structure, easily implements.

Embodiment
The novel blast-furnace charge level detector, mainly the computer 5 that is connected with motor 3 by material level stock rod 1, the windlass 2 that is connected with material level stock rod 1, the motor 3 that is connected with windlass 2, by lead 4 is formed.It is connected signal processing card 6 on the lead 4 between motor 3 and the computer 5.Time module 7 that is fitted with in the signal processing card 6 and signal processing module 8 are by proprietary bus and computer 5.
Blast furnace material level stock rod moves by the windlass of driven by motor, if the stock rod weight arrives charge level in stock rod test process, can be subjected to stopping of material immediately, cause the reducing of torque of motor, and because the material charge level is a kind of non-level shape, toppling over to the side appears in the interaction of the holder power that weight can make progress because of downward speed and material naturally, this situation can cause further the reducing of torque of motor, and only just these operating modes can appear when stock rod normally contacts charge level, therefore, in stock rod test process, signal processing card is gathered the stock rod depth signal of motor in real time, processing by time module in the information processing card and signal processing module, false false signal under the rejecting abnormalities situation, send correct stock rod depth signal to computer, for blast furnace monitoring and other application systems provide real material level signal.
Claims (2)
1, novel blast-furnace charge level detector, mainly the computer (5) that is connected with motor (3) by material level stock rod (1), the windlass (2) that is connected with material level stock rod (1), the motor (3) that is connected with windlass (2), by lead (4) is formed, and it is characterized in that: be connected signal processing card (6) by lead (4) between motor (3) and computer (5).
