Abstract
The utility model belongs to the technical field of chain grate machine equipment, and particularly relates to a chain grate machine water cooling shaft which comprises a hollow shaft. The chain grate machine water cooling shaft is characterize in that a group of shaft sleeves are axially welded to the surface of the hollow shaft, a key groove is arranged between each two shaft sleeves, and the key grooves are arranged in the surface of the hollow shaft. According to the chain grate machine water cooling shaft, water leakage and shaft breaking of the water cooling shaft can be effectively eliminated, shut-down of a palletizing production line caused by water leakage and the shaft breaking of the water cooling shaft are avoided, service life of the water cooling shaft is prolonged by 2-3 times, and therefore expenses costed by accidental shut-down are saved, and safe and stable operation of the palletizing production line is guaranteed.
Description
Technical field
The utility model belongs to the chain-grate machine equipment technical field, especially relates to a kind of chain-grate machine water-cooling shaft.
Background technique
Present domestic more than 20 the chain grate-rotary kiln acidic oxidation pellet production line that have is all take chain-grate machine, rotary kiln, central cooler as main equipment.Chain-grate machine is one of three large visual plants of acidic oxidation pellet production line, and its effect has two: one, and green-ball is carried out drying, and Dry run is done section at drum and finished with the section of draining, and the temperature that drum is done section is 180～250 ℃, and the temperature of the section of draining is 350～400 ℃; The 2nd, green-ball is carried out preheating, warm is finished in preheating I section and preheating II section.The temperature of preheating I section is 630～650 ℃, and the temperature of preheating II section is 980～1000 ℃.Water-cooling shaft is a vitals of chain-grate machine travelling mechanism, and water-cooling shaft is installed in preheating I section and preheating II section, and sprocket wheel, flat wheel are installed on the water-cooling shaft, and Main Function is to support grate, makes its smooth running.Former water-cooling shaft is to process circular groove at quill shaft, and sprocket wheel peace wheel is installed in the circular groove, and is in service because the water-cooling shaft fracture often occurs in the circular groove position in the effect of high temperature and alternate load, causes that water-cooling shaft leaks, and causes system shutdown.Owing to after systematic failures stops, must repairing process, therefore increased expense, affected simultaneously pellet output.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, is difficult for fracture and leaks, the chain-grate machine water-cooling shaft that the life-span is longer.
The purpose of this utility model realizes by following technical proposals:
Chain-grate machine water-cooling shaft of the present utility model comprises quill shaft, it is characterized in that being welded with vertically one group of axle sleeve on described quill shaft surface, and is provided with a keyway between per two axle sleeves, and described keyway is located at described quill shaft surface.
Advantage of the present utility model:
The utility model can eliminate effectively that water-cooling shaft leaks and off-axis, avoided because water-cooling shaft leaks and off-axis, the pellet production line system shutdown that causes, and water-cooling shaft increases 2-3 doubly working life, thereby saved the expense that stops production and occur because of accident, guaranteed pellet production line safety, stable operation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of chain-grate machine water-cooling shaft comprises quill shaft 1, it is characterized in that being welded with vertically one group of axle sleeve 2 on described quill shaft 1 surface, and is provided with a keyway 3 between per two axle sleeves 2, and described keyway 3 is located at described quill shaft 1 surface.
The utility model is because the circular groove that adopts axle sleeve 2 to replace on original water-cooling shaft, and at quill shaft 1 processing keyway 3, sprocket wheel peace wheel is positioned, solved the effect because of processing technology defective, high temperature and alternate load so fully, what the water-cooling shaft fracture that causes caused leaks and off-axis, causes system shutdown.
Claims (1)
1. a chain-grate machine water-cooling shaft comprises quill shaft, it is characterized in that being welded with vertically one group of axle sleeve on described quill shaft surface, and is provided with a keyway between per two axle sleeves, and described keyway is located at described quill shaft surface.
