Description
Technical field
The utility model relates to a kind of leak detection assembly, relates in particular to a kind of blast furnace tuyere small sleeve leak detection assembly.
Background technology
In production practice, safety and output that the direct relation blast furnace is produced in the breakage of blast-furnace tuyere, therefore, the leak detection of blast-furnace tuyere is an emphasis in the detection of blast furnace instrument.The method of taking for the leak detection of blast-furnace tuyere at present mainly contains two kinds: one is imported and exported the difference in flow of water-cooled tube for detecting tuyere small sleeve, and it two imports and exports cooling ranges for detecting tuyere small sleeve; Most of blast furnace is taked the parallel mode of two kinds of ways.Usually, because when the blast furnace tuyere small sleeve water-cooled tube has just begun to leak, small opening is less, so the leakage of cooling water amount is also less, no matter less spillage is that the influence that produces to the flow of water coolant or to the temperature of water coolant is all less, add the precision influence of flow and temperature instrument, be difficult to be detected at the tuyere small sleeve initial stage of leaking, when being detected, general leaked more serious, the slow leak detection assembly of this response speed has been difficult to satisfy fully the needs of blast furnace safety in production, brings certain influence for the safety in production of blast furnace and the quality of production inevitably.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, blast furnace tuyere small sleeve leak detection assembly that response speed is fast.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of blast furnace tuyere small sleeve leak detection assembly, this blast furnace tuyere small sleeve comprises air water separator, measures jar and liquidometer with leak detection assembly, on the wall of air water separator, be provided with water inlet pipe and water shoot, and on water shoot, be provided with valve, air water separator is communicated with airway with the upper end of measuring jar, upper end at the measurement jar is provided with water filling port, is provided with the benchmark liquid level tube in the lower end of measuring jar, and liquidometer is located at a side of measuring jar.
Compared with prior art, the utility model technology has the following advantages:
1, the utility model is simple in structure, response speed is fast.When blast furnace tuyere small sleeve leaks, it is less when leaking hole begins, water coolant is by outwards ejection rapidly in the tuyere small sleeve, just formed a little local decompression district at scupper this moment, the outer gas of little cover just enters tuyere small sleeve in a large number, gas is separated and enters the measurement jar along airway in air water separator, owing to measure in the jar pouring in of a large amount of gases arranged, the pressure of measuring jar top is increased rapidly, to measure pot liquid extrudes outside the jar, the liquid level of measuring jar is descended fast, and liquidometer spreads out of the liquid level change value.Owing to, just have a large amount of gas and enter the measurement jar at the initial stage that little cover leaks, the leak detection time is shifted to an earlier date greatly, therefore, response speed of the present utility model speeds.
2, the utility model is convenient to make.In the utility model, air water separator and measurement jar are container cylindraceous, and the annexation between each parts can connect with screw thread or flange, and making and processing are got up all very convenient.Inlet, outlet at air water separator can be given first welding flange short tube, can give the short silk of welding earlier in the air water separator upper end, and separator can be connected fast with water inlet pipe, water shoot and airway.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model blast furnace tuyere small sleeve with leak detection assembly.
Embodiment
With reference to Fig. 1, a kind of blast furnace tuyere small sleeve leak detection assembly, this blast furnace tuyere small sleeve comprises air water separator 1, measures jar 3 and liquidometer 6 with leak detection assembly, on the wall of air water separator 1, be provided with water inlet pipe 11 and water shoot 12, and be provided with valve 13 on water shoot 12, air water separator 1 is communicated with airway 2 with the upper end of measuring jar 3, is provided with water filling port 4 in the upper end of measuring jar 3, be provided with benchmark liquid level tube 5 in the lower end of measuring jar 3, liquidometer 6 is located at a side of measuring jar 3.
In the present embodiment, the blast furnace tuyere small sleeve return water pipe is connected with the water inlet pipe 11 of air water separator 1, liquidometer 6 adopts magnetic turnover panel liquidometer, and model is LI015.
Before using the utility model, open the valve 13 on the water shoot 12 of air water separator 1, in air water separator 1, add water, valve 13 is closed for a moment, make the liquid level of air water separator rise to certain altitude, at this moment, open valve 13, keep air water separator 1 water inlet pipe and water outlet pipe flow identical, it is constant that the liquid level in the air water separator 1 keeps; Add water in measuring jars 3 water filling port 4, there are flowing out until the mouth of pipe of benchmark liquid level tube 5, with water filling port 4 sealings, to liquidometer 6 power supplies, this moment, liquidometer 6 was measured the height of benchmark liquid level, and this new device is manufactured and finished.When blast furnace tuyere small sleeve leaks, gas in the blast furnace is just molten in water-cooled tube rapidly, a large amount of gas takes air water separator 1 to return water pipe, gas is separated and enters measurement jar 3 along airway 2 in air water separator 1, owing in the measurement jar 3 pouring in of a large amount of gases arranged, the pressure on measurement jar 3 tops is increased rapidly, will measure outside jar 3 interior liquid extrusion jars, the liquid level of measuring jar 3 is descended fast, and liquidometer 6 spreads out of the liquid level change value.Owing to, just have a large amount of gas and enter the measurement jar at the initial stage that little cover leaks, the leak detection time is shifted to an earlier date greatly, therefore, response speed of the present utility model speeds.
