Description

Cold quick-witted water-stop structure of modified ring

Technical Field

The utility model relates to an improved water sealing structure of a circular cooler.

Background

The circular cooler is an annular cooling device, and is provided with three cooling sections, the furnace cover is divided into three sections, each cooling section is separated by a wind-shield wall, the distance between the wind-shield wall and the trolley grate is about 750mm, and each section is provided with a cooling fan. The cooling process of the circular cooler comprises the following steps: the temperature of material pellets discharged by a rotary kiln is 1100 ℃, the first cooling section feeds hot air with the temperature of 1100 ℃ into the kiln as secondary air to improve the temperature in the kiln, the second cooling section flows hot air with the temperature of about 1000-800 ℃ into a grate machine preheating section to be used as a supplementary heat source to improve the production efficiency and the product quality, the thermotechnical sealing of a rotary body of a circular cooler is of great importance in the process of producing oxidized pellets by the grate machine, the rotary kiln and the circular cooler, the thermotechnical sealing of each thermotechnical section of the circular cooler is realized to be uniform and stable, the method is a necessary measure for improving the production efficiency and the product quality of the grate machine, the rotary kiln and the circular cooler, the sealing mode and the improvement thereof directly influence the working efficiency and the service life of maintenance operation, and the simple and efficient sealing and fixing method is used by changing the sealing and fixing mode, thereby playing an important role in the production process and the maintenance process.

The water seal of the Mongolian storehouse pellet circular cooler is always made of stainless steel, the plastic fracture heat distortion is large, the installation height and the position of the water seal are unreasonable, the upper horizontal plane of the trough body and the heat insulation baffle plate brick are at the same horizontal height, the water seal trough body water does not soak the upper structure and passes through a high-temperature region and a low-temperature region in a reciprocating way in the operation process, the water seal trough body deforms to different degrees, the butt welding seam of each section of the trough body cracks, the leakage water level of cooling water in the trough body drops, the water seal begins to aggravate the thermal deformation cracking, the wind insulation effect fails, the air flow at a high temperature of thousands degrees flows out, the structures such as the water trough and the water insulation sealing plate are seriously deformed, the pellet resistant materials drop greatly, the circular chain hot air system is disordered, the improvement of the operation rate of the circular cooler equipment is seriously restricted, the maintenance shutdown caused by the problem is carried out every month, the maintenance workload is large, the maintenance cost is high, and the service cycle is short, the stable operation of production is severely restricted, the production is required to be stopped immediately for repair, and the accidents are processed up to 1000 ten thousand yuan in 2020 in an accumulated way.

Disclosure of Invention

The utility model aims to provide an improved water sealing structure of a ring cooling machine, which can effectively avoid a high-temperature area, prolong the service life of the structure and avoid the deformation and damage of a water sealing groove body.

The technical scheme adopted by the utility model is that the improved water sealing structure of the ring cooling machine comprises a water sealing groove body arranged at the position of a heat insulation fence brick, wherein the water sealing groove body is formed by mutually buckling an upper groove body and a lower groove body, the lower groove body is filled with cooling water to form a water seal, the distance between the peripheral walls of the upper groove body and the lower groove body and the heat insulation fence brick is enlarged by 100mm compared with the original distance, the cross section of the lower groove body is in a concave shape, an annular gap is reserved between the inner peripheral wall of the lower groove body and the heat insulation fence brick, a heat insulation layer is filled in the lower groove body, and the height of the lower groove body is reduced to 250 mm.

Along with the enlargement of the scale of a company, the requirements on the pellet mineral product and the pellet quality are higher and higher, according to the practical situation, a boiler steel plate with small thermal deformation is adopted to manufacture a water seal, the original design height of the water seal is reduced, the original design height is reduced to 250mm from 300mm, the width is kept unchanged, the diameter of an inner-outer ring water seal groove body is changed, the distance between the groove body and a heat insulation refractory breast board brick is enlarged by 100mm, a high-temperature area is avoided, the repeated accidents are avoided, about 120 hours are saved during the whole year, and the production loss can be effectively controlled and saved by about 1000 thousands.
