Description
Technical field:
The utility model relates to a kind of equipment in the metallurgical ironmaking processes, the molten iron liquid surface measuring device of during particularly a kind of blast furnace casting torpedo pot iron water liquid level being monitored.
Background technology:
Need monitor torpedo pot iron water liquid level during blast furnace casting, at present adopt the ways of weighing to measure more, its weighing value error is bigger, and the security when tapping a blast furnace is relatively poor; Need in addition according to iron mouth quantity, every blast furnace need be installed 6-8 platform track scale, and not only one-time investment is big for this, and the installation of track scale, maintenance workload are big, the maintenance cost height.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and a kind of molten iron liquid surface measuring device is provided, and this device not only can accurately be measured the molten iron liquid level in the torpedo jar, and equipment manufacturing cost is low, installation and maintenance are very convenient.
The technical solution of the utility model is: a kind of molten iron liquid surface measuring device is characterized in that: be made up of power supply, radar detedtor, signal processing apparatus, CPU and display; Wherein, radar detedtor is connected with signal processing apparatus, and the output port of signal processing apparatus is connected with the input port of CPU, and the output port of CPU is connected with the pulpit with display.
Described CPU adopts programmable controller PLC.
The utility model has the advantages that: 1, can accurately measure the molten iron liquid level in the torpedo jar, degree of accuracy can reach 0.1/FS.2, equipment manufacturing cost is low, installation and maintenance are very convenient.3, can improve security when tapping a blast furnace.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is an electrical schematic diagram of the present utility model
Embodiment:
As shown in Figure 1: a kind of molten iron liquid surface measuring device, form by power supply, radar detedtor, signal processing apparatus, CPU (programmable controller PLC) and display; Wherein, radar detedtor is connected with signal processing apparatus, and the output port of signal processing apparatus is connected with the input port of CPU, and the output port of CPU is connected with the pulpit with display.
As shown in Figure 2: air switch SW1 (model C 65N-2P), SW2 (model C 65N-1P) are connected with connection terminal L1, the N of direct supply PS (model 6EP1331-1SH02), the connection terminal N of power supply is connected with CPU, and connection terminal L, the N of CPU is connected with air switch SW3, SW4 (model C 65N-1P) respectively with COMO; The connection terminal 1,2 of distributor LY1 (model MSC202-1033) is connected with expansion module EM1, and connection terminal 4,5 is connected with the computer based control system DCS with analogue input template.Distributor LY2 model MSC202-1033) connection terminal 1,2 is connected with expansion module EM2, and connection terminal 4,5 is connected with the computer based control system DCS with analogue input template.Expansion module EM1, EM2 and DCS can receive the input signal of 4-20mA.
Digitized representation connection terminal in the equipment frame, digitized representation wire size on the line or cable number.
Principle of work of the present utility model is: be installed on the radar detedtor that is positioned at torpedo jar top on the cast house platform and constantly launch Continuous Wave with frequency modulation to the torpedo jar, microwave turns back to radar detedtor after arriving the molten iron liquid level again, because the speed of microwave is constant, so measure the time that is transmitted into reception, promptly know the distance of detector to the molten iron liquid level.The microwave that turns back to radar detedtor outputs to CPU through the analog quantity with 4-20mA after the processing of signal processing apparatus, and last CPU outputs to display and pulpit with signal.
