Protection device for water seal tank of ring cooler

The utility model discloses a protection device for a water seal tank of a ring cooler. The water seal tank is in a circular ring shape and is located on a support plate of a trolley breast board. The protection device is characterized in that three U-shaped grooves are evenly formed in an annular ring of the water seal tank and embedded in the water seal tank through welding; the lower portion of the water seal tank is provided with a positioning plate which is fixed to the support plate, a through hole is formed in the middle of the positioning plate, and a drill key is inserted into the through hole to be clamped and fixed. According to the protection device, the service cycle of the water seal tank of the ring cooler is prolonged, it is ensured that sealing medium water in the water seal tank does not leak, in this way, the water seal tank is at a low working temperature, and the phenomena that the water seal tank deforms, snaps, is blocked and the like are avoided; stable operation of the equipment is facilitated; the performance of sealing between a fixed gas hood on the ring cooler and a revolved body is improved, high-temperature hot gas and dust are prevented from leaking, heat loss is reduced, and the working environment is improved.
