Description

Technical Field

[0001] The utility model relates to an improved sealing structure of a water quenching tank. Background Art

[0002] The water cooling device in the continuous hot-dip galvanizing process of the cold rolling branch factory consists of a deflector roll, a quenching tank, a spray pipe and a squeezing roll. Location: at the bottom of the galvanizing tower and on the 1st and 2nd floors. Function: The strip steel is cooled by water quenching and dried by a dryer to reach a temperature of about 40° required to enter the tension leveling machine. Composition and structure: The quenching tank equipment consists of a quenching tank, a squeezing roll, a spray pipe, a nozzle, etc. The quenching tank is a welded steel plate structure. The spray pipe is installed in the quenching tank. The outside of the tank body is connected to a circulation pump, and the cooling water used is demineralized water.

[0003] Current situation problems: The existing water quenching sealing device uses double flanges plus asbestos rope for sealing. During the production process, a strip break accident occurs. When dealing with it, it is necessary to open the flange for threading operation, and seal it again after the operation is completed. Disadvantages: There are a total of 40 bolts connecting the method flanges, and the disassembly and installation time is about 1 hour; the sealing quality of the method flanges cannot be guaranteed, and water leakage frequently occurs; the water leakage part is 5 meters away from the zinc pot, forming a major safety hazard; the cost of demineralized water is high and it cannot be recycled. Summary of the Invention

[0004] The purpose of the utility model is to provide an improved sealing structure of a water quenching tank, which can prevent water leakage, ensure on-site safe production, improve the operation rate, and reduce costs and increase efficiency.

[0005] The technical solution adopted by the utility model is an improved sealing structure of a water quenching tank, which includes a method flange. A 50-mm-wide angle steel is installed in the inner hole of the method flange to form a slideway. A 100-mm-wide sealing steel plate is arranged at the bottom of the method flange to ensure the smooth return of cooling water to the water quenching tank. An insertion plate is arranged in the method flange and is fixed by 30-mm angle steel plus galvanized steel plate. A steel pipe with a diameter of 10 mm is welded in the middle of the insertion plate to facilitate the disassembly and assembly of the insertion plate.

[0006] After the modification of the water quenching tank sealing device, it has been achieved that: opening and restoring the water quenching tank hole only requires a single person to operate for 2 minutes; no water leakage phenomenon occurs again; the occurrence of safety hazards is effectively eliminated. Brief Description of the Drawings

[0008] Figure 2 It is the side view of the utility model. Embodiment

[0009] An improved sealing structure of a water quenching tank, as Figure 1 、 2As shown in the figure, it includes a method flange. An angle steel with a width of 50 mm is installed in the inner hole of the method flange to form a slideway 2. A sealing steel plate 1 with a width of 100 mm is arranged at the bottom of the method flange to ensure the smooth return of cooling water to the water quenching tank. An insertion plate is arranged in the method flange and fixed with 30 mm angle steel and galvanized steel plate. A steel pipe 3 with a pipe diameter of 10 mm is welded in the middle of the insertion plate to facilitate the disassembly and assembly of the insertion plate.

Claims

1. An improved water quench tank sealing structure, comprising a square flange, characterized in that: A 50mm wide angle steel is installed in the inner hole of the method flange to form a slideway. A 100mm wide sealing steel plate is set at the bottom of the method flange to ensure that the cooling water can flow back smoothly to the water quenching tank. A plug-in plate is set in the method flange, which is fixed with a 30mm angle steel and a galvanized steel plate. A 10mm diameter steel pipe is welded in the middle of the plug-in plate to facilitate the disassembly and assembly of the plug-in plate.
