In order to improve working conditions, increase the service life, the both sides of above-mentioned bearing are equipped with oil-sealing arrangement and dust ring.
For helical axis being expanded freely and not influencing its running, one end of above-mentioned helical axis is connected with swivel joint by bearing block, be provided with sleeve in the described bearing block, described sleeve links to each other with described helical axis by flat key, and the bearing in the described bearing block is installed on the described sleeve.
For sealing effectiveness that improves helical axis and furnace wall interface and don't the running that influences helical axis, the interface of above-mentioned furnace wall and helical axis is built by laying bricks or stones according to the shaft shoulder profile of helical axis, and the joint of described furnace wall and described helical axis is provided with seal felt.
For the resistance to elevated temperatures of the helical blade that improves helical axis and at high temperature wearability and intensity, and accumulation results in blockage in the exit to prevent material, hinder the rotary furnace ordinary production, the helical blade of described helical axis is a carbide alloy, and the end of described helical blade discharging is a backpitch.
In order to reduce configuration, compact conformation and to reduce floor space, establish water cooling tube in the above-mentioned helical axis, described water cooling tube is connected with water inlet, water return outlet by swivel joint, and described water inlet, water return outlet are located at an end of helical axis.
Setting is no less than 4 gripper shoe in the above-mentioned helical axis, is used to support above-mentioned water cooling tube.
In order to prevent that the cooling water in the helical axis from forming stagnant water, above-mentioned gripper shoe is provided with opening along the helical axis circumferencial direction, can change the flow direction of cooling water.By the different combination of the opening direction of described gripper shoe, cooling backwater can not form stagnant water.
Adjust the position during installation and maintenance of helical axis for convenience, about above-mentioned bearing block and bottom all is equipped with the adjustment bolt.
The utlity model has following beneficial effect, the bearing block at the utility model helical axis two ends is water-cooling bearing block and is installed on the furnace wall, by furnace wall and described helical axis joint seal felt is set, oil-sealing arrangement is set in the both sides of bearing and dust ring seals, helical blade adopts carbide alloy and is made as backpitch at the end of discharging and stops up to prevent material, and the flow direction that gripper shoe changes cooling water is set in helical axis, prevent to form stagnant water, not only reach good sealing effectiveness and do not influence helical axis thermal expansion and running at high temperature again, the service life that helps extension fixture, and it is simple in structure, compactness, reliable operation.
