Abstract
Description
Technical Field
[0001] The utility model relates to the field of heating furnace equipment in steel plants, namely, a connector-type heating furnace water seal tank, which can enable an input-type liquid level meter to accurately and stably detect the liquid level in the water seal tank. Background Art
[0002] In the prior art, the water seal groove of the heating furnace is used to seal the opening of the furnace bottom where the movable beam column passes through, to prevent the cold air outside the furnace from being sucked into the furnace. The water seal groove is located between the furnace bottom steel structure and the translation frame. Its cross section is W-shaped and is installed on the translation frame. A scraper plate is provided at the lower part of the furnace bottom steel structure at the furnace bottom opening, which is immersed in the water seal groove to achieve water sealing. Figure 3 .
[0003] In the heating furnace system, the water seal tank plays a major role in preventing gas leakage accidents. The water seal level inside is an important monitoring parameter in the heating furnace control system. There are 4 detection points, 2 at the loading end and 2 at the discharging end. There was no place to place the level meter in the original design. The level meter could only be put into the water seal tank and the cable was simply fixed with wire. Around the opening where the movable beam column passes through the furnace bottom, it is built with furnace bottom hole bricks formed by castables, and the brick masonry height is 150mm higher than the furnace bottom to prevent slag from falling into the water seal tank. Despite this, a small amount of iron oxide scale and refractory materials that fall off after the furnace has been running for a long time will still fall into the water seal groove from the opening where the movable beam passes through the furnace bottom. In this way, the slag will be scraped to the charging end of the furnace tail through the relative movement of the moving water seal groove and the scraper plate fixed on the steel structure of the furnace bottom. Because the liquid level meter is directly put into the water seal groove, with the relative movement of the moving beam and the water seal groove, the length of the water seal groove is 7 meters, the water surface shakes greatly in a large space, and the liquid level meter will also swing in the water, which can easily cause inaccurate detection data and cable wear. Sometimes the liquid level meter body will be cut off by the scraper plate, which not only affects the stable operation of the equipment but also is not easy to maintain. Utility Model Content
[0004] The purpose of the utility model is to provide a connector type heating furnace water seal tank which can operate accurately and stably in view of the above-mentioned shortcomings.
[0005] The technical solution of the utility model is: a connector type heating furnace water seal tank, including a tank body, a slag scraper plate is arranged in the tank body, and the characteristic is that an orifice is opened on the side of the tank body, an upper open liquid level detection tank connected with the orifice is welded, and a liquid level meter is installed in the upper open liquid level detection tank.
[0006] The above scheme also includes:
[0007] The height between the orifice and the bottom of the tank is 200 mm.
[0008] The tank body is arranged in multiple connections, and four liquid level gauges are set around it.
[0009] The water seal tank detection structure is improved by using the communicating vessel principle. The so-called communicating vessel is two or more containers interconnected below the liquid level. The communicating vessels contain the same liquid and have equal pressure on the liquid surface. The liquid levels are equal. Four liquid level detection tanks are made at four locations convenient for maintenance at the loading and discharging ends of the water seal tank and welded to the water seal tank. A communicating hole is provided at the bottom of the welding point to connect to the inside of the water seal tank, so that the liquid level in the detection tank is the same as that in the water seal tank.
[0010] The advantages of the utility model are: 1. After improvement, the device is provided with an upper open liquid level detection slot connected to the tank body, and a liquid level meter is installed in the upper open liquid level detection slot, which can accurately detect the liquid level of the water seal tank, improving the stability of the liquid level value. The installation position of the liquid level meter is separated from the water seal tank body, on the outside, with a small space, and there will be no shaking of the water surface, and the liquid level meter will not be scratched by the equipment in the water seal tank. The liquid level meter does not shake, the detection is accurate, and the service life of the liquid level meter is extended. 2. After the use of this set of devices, the service life of the liquid level meter is increased from the original 3 months to more than 3 years.
