Description

Masonry structure of circular cooler receiving hopper lining

Technical Field

The utility model relates to the field of masonry structures of refractory materials, in particular to a masonry structure of a receiving hopper lining of an annular cooler.

Background

The circular cooler is one of main equipment in the oxidized pellet production process. In the technological process of 'grate-rotary kiln-circular cooler', the device is used for cooling the pellets discharged from the rotary kiln at about 1200 ℃ and recovering waste heat so as to achieve the purpose that the pellets are suitable for transportation. In order to meet the requirement of stable operation of the annular cooler at a high temperature, each part of the annular cooler is protected by refractory materials with certain thickness, a receiving hopper of the annular cooler is an interface part of the rotary kiln and the annular cooler, and high-temperature pellets discharged from the rotary kiln are scattered to a trolley below through the receiving hopper.

The existing material blocking wall of the material receiving hopper of the annular cooler is generally built by integrally pouring a refractory lining or by adopting refractory bricks, and because the castable at the wall part of the material receiving hopper material blocking wall is extremely easy to damage under the long-time scouring and abrasion of high-temperature materials, the existing material blocking wall is required to be shut down for trimming once damaged and peeled off, and the replacement frequency is higher, and the material receiving hopper is of an integrally pouring type lining structure, the quality is inferior, the precast bricks are stable and easy to control, and the precast bricks are difficult to bake in place, so that the strength is low and the scouring resistance is not realized; the structure built by the refractory bricks is poor in structural stability, and the whole collapse can be caused by local damage; in addition, there is a structure built by prefabricated bricks with metal anchoring elements, the metal anchoring nails extending out of the upper parts of the prefabricated bricks are welded on a steel plate of a furnace body to improve structural stability, but all the prefabricated bricks of the prefabricated brick building structure are welded on the steel plate of the furnace body, the metal anchoring nails extending out of the upper parts of the prefabricated bricks are inserted into grooves at the lower parts of another prefabricated brick to form seamless fit, so that replacement is difficult, a plurality of prefabricated bricks above the prefabricated bricks need to be removed when a specific prefabricated brick is replaced, and the last prefabricated brick in a row cannot be put in due to the metal anchoring nails extending out of the upper parts of the prefabricated bricks, and the prefabricated brick can only be repaired by adopting a pouring material beating mode. Accordingly, a masonry structure of a receiving hopper lining of an annular cooler is needed at present, and the masonry structure has the advantages of being long in service life, stable in structure and convenient to replace and maintain.
