Description
Technical field
What the present invention relates to a kind of leak hunting method and device thereof, particularly blast furnace cooling stave suppresses leak hunting method and device thereof.
Background technology
Blast furnace cooling stave is fixed on the blast furnace furnace wall, and interior block refractory materials according to national regulation and operational procedure, requires will suppress one by one before installation.A blast furnace cooling stave has hundreds of, and traditional suppressing is to tighten with buckle to suppress or the movable joint connection, and be time-consuming.
The tradition hammering method is: when cooling stave dispatches from the factory, according to its mouth of pipe of type of attachment with pipeline two kinds of patterns are arranged: large blast furnace (promptly 1200 upright more than) is welding, the cooling stave mouth of pipe is flat mouthful, fix (seeing accompanying drawing 3) with sebific duct and snap ring when suppressing, because last sebific duct and stubborn snap ring are taken a lot of work very much, so an articulating gets off more with regard to the time spent; Small blast furnace (promptly 1200 upright following) generally adopts bolt to connect for easy for installation, and the cooling stave mouth of pipe is a screw thread, connects (seeing accompanying drawing 4) with movable joint when suppressing must align because loose joint connects, and twine the network flax silk could be water-tight, so spend a lot of times.
Summary of the invention
In order to solve problems of the prior art, the invention provides a kind of blast-furnace cooling wall hammering method and device thereof, solve the problem that traditional hammering method is time-consuming and cost is high.
The present invention is achieved by the following technical solutions: a kind of blast-furnace cooling wall hammering method may further comprise the steps:
Measure cooling stave pipe 1 internal diameter, select diameter less than the processing of the cooling stave bore pipe of fetching water, and in its outer wall machining screw;
The processing ring flat-plate makes its external diameter less than the cooling stave bore, and internal diameter is greater than the processing pipe diameter of fetching water;
The configuration rubber ring, its thickness is 30 ~ 40mm, and the rubber ring external diameter is less than the cooling stave bore, and internal diameter is greater than the processing pipe diameter of fetching water;
According to processing fetch water the pipe outer wall the screw thread arrangement bolts at two ends;
Order according to bolt, ring flat-plate, rubber ring, ring flat-plate, bolt links into an integrated entity with inner sleeve, tightens top bolt respectively and makes the rubber ring pressurized, produces friction and plays sealing function with the cooling stave pipe; Start pressuring pump, fetch water by processing and manage slow full topped up with water, observe rubber ring sealing situation, discovery is leaked holding bolt till reaching water pressure testing again.
The described processing pipe diameter d=D-20mm that fetches water.
Described ring flat-plate external diameter is D-3mm, and internal diameter is d+2mm, and thickness is 5mm.
Described rubber ring thickness is 30 ~ 40mm, and external diameter is D-5mm, and internal diameter is d+5mm.
A kind of blast-furnace cooling wall hammering device, comprise pressuring pump and the processing pipe of fetching water, described processing is fetched water the pipe diameter less than the cooling stave bore, described processing fetch water the pipe outer wall be provided with screw thread, two bolts that are complementary with described screw thread are by screw thread and the processing pipe coupling of fetching water, set gradually [, rubber ring and ring flat-plate between the described bolt, described ring flat-plate and rubber ring external diameter be less than the cooling stave bore, and internal diameter is greater than the processing pipe diameter of fetching water.
The advantage of blast-furnace cooling wall hammering method provided by the invention and pressure device is: adopt the method for rubber sheet gasket, the cooling stave of this method quovis modo all is suitable for, and saving of work and time can reduce labour cost greatly, enhances productivity.
Description of drawings
Fig. 1 is eight pipelines of blast furnace cooling stave.
Fig. 2 is for adopting the pressure device of the inventive method.
Buckle type of attachment device when Fig. 3 suppresses for tradition.
Fig. 4 form device that is threaded when suppressing for tradition.
Among the figure, 1, pressuring pump, 2, the processing pipe of fetching water, 3, the cooling stave tube wall, 4, ring flat-plate, 5, rubber ring, 6, bolt, 7, movable joint (screw thread mates with the pipe screw thread), 8, flax silk or adhesive tape, 9, buckle, 10, the rubber pipe of fetching water.
Embodiment
At first measure cooling stave pipe 3 internal diameters, be generally D=57～60mm, select processing to fetch water according to caliber D then and manage 2, process the pipe 2 of fetching water and to select thick-walled tube, so that in the outer wall machining screw, diameter is d=35～40mm (little two standard deviations), is generally d=D-20mm; The 3rd step processing ring flat-plate 4, its external diameter ￠=D-3mm, internal diameter ￠=d+2mm, thickness are 5mm; The 4th step configuration rubber ring 5, rubber requires good springiness, and certain degree of hardness is arranged, and its thickness is 30～40mm, and external diameter is D-5mm, and internal diameter is d+5mm; The bolt 6 at lower ring plate 4 two ends is gone up in configuration at last.
As shown in Figure 2,2 link into an integrated entity according to the order and the processing of bolt 6, ring flat-plate 4, rubber ring 5, ring flat-plate 4, bolt 6 pipe of fetching water, process some covers (eight mouths of pipe as shown in Figure 1 according to the mouth of pipe number of cooling stave, so processing eight covers), by suppressing graphic connecting, tighten top bolt 6 respectively and make rubber ring 5 pressurizeds, produce friction and play sealing function with cooling stave pipe 3.Start pressuring pump 1, slow full topped up with water is observed rubber ring 5 sealing situations, finds to leak holding bolt 6 till reaching water pressure testing again.The pressure that generally tries the water is 0.4MPa, and voltage stabilizing 30 minutes is water-tight to be qualified, two of the personnel selections of trying the water of a cooling stave, and 45 minutes times spent were a circulation, finished 13 every day.The device of being processed can reuse, and has saved very big expense.
The device of the inventive method is simple, and easily processing is with low cost, simple to operation, and the time spent is short, and can accurately detect the situation of leaking of blast furnace cooling stave, can reduce labour cost greatly, enhances productivity.
