Specialized combined type sealing device for incinerator

Abstract

The invention provides a specialized combined type sealing device for an incinerator. The specialized combined type sealing device for the incinerator comprises a rotary kiln, a labyrinth sealing partand a graphite block sealing part, wherein the labyrinth sealing part and the graphite block sealing part are arranged at the two ends of a kiln body of the rotary kiln; the labyrinth sealing part comprises a support, a flange, a sealing ring, a friction plate and a sliding key; the support is arranged on the rotary kiln; the flange is arranged on the support; the sealing ring is arranged at theleft side of the flange; the friction plate is arranged at the left side of the sealing ring; labyrinth sealing is formed by the flange, the sealing ring and the friction plate; and the sliding key isarranged at the lower end of the sealing ring. The specialized combined type sealing device for the incinerator has the beneficial effects that the specialized combined type sealing device for the incinerator has a good sealing effect and a stable performance and is simple in structure by adopting rotary kiln feeding and discharging combined type sealing; gas leakage and dust leakage are avoided;the working efficiency of the rotary kiln is improved; the secondary pollution is reduced; the environmental protection requirements are satisfied; and the cost is saved.

Description

technical field [0001] The invention relates to the field of garbage disposal, in particular to a special combined sealing device for an incinerator. Background technique [0002] In the waste treatment industry, the waste incineration kiln is the main equipment in the whole process. It is necessary to incinerate these high-risk wastes so that the harmful dust and harmful gases in the incineration will not leak and the air leakage rate will be reduced. Therefore, the seals at both ends of the rotary kiln is the key. At present, when sealing the inlet and outlet positions of the rotary kiln, it is usually sealed by a simple sealing ring, but the above-mentioned sealing effect is insufficient, which easily leads to the leakage of exhaust gas in the rotary kiln. Therefore, it is particularly important to solve the problem that the sealing work at both ends of the rotary kiln is not easy to complete.
