Abstract

The invention relates to the field of blooming furnace observation devices, in particular to a pneumatic advancing-retreating belt sweeping and protection device with a short and exquisite structure.The device comprises a thermal imager, a closed air cylinder, a ball valve, a transition sleeve, a base guide pipe and a water jacket fixedly mounted on the base guide pipe. A first flange and a second flange are fixedly arranged at the left end and the right end of the ball valve correspondingly. A third flange and a fourth flange are arranged at the left end and the right end of the transition sleeve correspondingly. The other end of the water jacket is fixedly mounted on the first flange. The fourth flange at the right end of the transition sleeve is fixedly connected with the first flangethrough bolts. The closed air cylinder comprises a cylinder barrel and a cylinder rod. A containing groove is formed in the cylinder rod. The thermal imager is fixedly mounted in the containing groovethrough a support. A front end cap is further arranged at the front end of the containing groove. A preformed hole is formed in the front end cap. The end of the cylinder rod of the closed air cylinder is fixedly connected with the third flange. The overall product structure of the device is short and exquisite, subsequent equipment maintenance is convenient, and the thermal imager can be protected.

Description

technical field [0001] The invention relates to the field of observation devices for ironmaking furnaces, in particular to a short and delicate structure pneumatic advance and retreat belt cleaning protection device. Background technique [0002] This product is mainly used in the production of metallurgical ironmaking blast furnace. It can observe the material level and the working condition of the distributor in real time on the sealed ironmaking furnace with pressure and gas. [0003] The original product uses infrared light source technology, and the production situation cannot be observed in real time without infrared light source. The product structure is the inner jacket / water jacket / ball valve plus nitrogen and automatic sweeping of the front end. When the air pressure drops / the water flow rate is too low or too high, it cannot automatically exit and protect the internal equipment in time, causing equipment damage and affecting production. At the same time, under th...
