Description
Technical Field
The utility model belongs to the technical field of rotary kiln auxiliary assembly, specifically a rotary kiln hood sealing device.
Background
The rotary kiln is key equipment in the industries of cement, metallurgy, chemical industry and the like, is operated under negative pressure, and can reduce secondary air entering the kiln and secondary air quantity if excessive air leaks into a hot end, so that heat loss is caused; the negative pressure at the cold end is high, so that a large amount of cold air is easily sucked, a large amount of waste gas in the kiln is not easy to discharge, and the fuel cannot be completely combusted; dust is contained in cold end waste gas, and a large amount of dust can overflow due to accidental wind falling to cause pollution; the sealing is a tie connecting the cylinder body with the head and the tail cover, namely the moving body and the fixed body; therefore, the quality of the sealing has great significance for the high-efficiency operation of the whole process parameters and equipment; because sealed face gyration diameter is big, and work under adverse circumstances such as high temperature, high dust, the kiln body has expend with heat and contract with cold and reciprocal axial float, especially the kiln head barrel can produce great radial runout after operation a period, therefore kiln head sealing device should be able to satisfy following requirement: the sealing performance is good; the device can adapt to the shape error of the cylinder, in particular to the radial deflection of the cylinder; can adapt to thermal expansion and cold contraction and radial reciprocating movement of the cylinder body; the device can adapt to severe working environments such as high temperature, high dust and the like; the structure is simple, and the maintenance and the overhaul are convenient; the service life is long; to overcome the deficiencies in the prior art, one of the objects of the present invention is to solve one or more of the problems of the prior art.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to above-mentioned technical current situation, and provide a rotary kiln hood sealing device.
The utility model provides a technical scheme that above-mentioned technical problem adopted does:
the utility model provides a rotary kiln hood sealing device, includes a kiln body and a closed section of thick bamboo, kiln body rear is equipped with the kiln hood cover, link up through the fish scale interface between kiln hood cover and the kiln body, connect a cover of swirling at kiln body opening part, the cover of swirling is located the kiln hood inside, the outside of swirling the cover is equipped with a closed section of thick bamboo, closed section of thick bamboo is equipped with upright gusset all around.
One side of the closed cylinder is fixed with a cleaning door through a hand screw, and a sealing pressing plate compacting door plate is arranged on one side panel of the hand screw.
The vertical rib plate is made of cast iron.
The utility model has the advantages that: the utility model discloses a sealed section of thick bamboo is articulated with rotary kiln hood, and fixes through mobilizable seal pressing plate, has improved sealing performance, has reduced heat energy loss, sets up the clearance door on the sealed section of thick bamboo, and the junction of being convenient for clears up and observes.
