During the antimony smelting process, the sealing device at the head and tail of the rotary furnace is of paramount importance. This is primarily due to the unique operating mode of the furnace. During operation, the furnace body is in a continuous rotation state, while the inlet and outlet are fixed in position, which inevitably creates gaps between the moving and static components.

The sealing device is crucial for the furnace head. A poorly sealed furnace head can cause air leakage. Cold air can be drawn into the furnace through these unsealed gaps, severely damaging the carefully cultivated reducing atmosphere. This reducing atmosphere is crucial for the smooth progress of the antimony smelting reaction. Once disrupted, the smelting reaction will not proceed normally, resulting in reduced product quality. Furthermore, the inhaled cold air lowers the furnace temperature. To maintain the required smelting temperature, increased fuel input is required, which not only increases production costs but also reduces energy efficiency.

The furnace tail seal is also not to be underestimated. Failure of this seal can lead to tail smoke leakage. Antimony trioxide smoke is a valuable product of the antimony smelting process. Furnace tail smoke leakage can cause this valuable smoke to escape into the surrounding environment. This directly reduces metal yield and the company's economic benefits. Furthermore, the escaped smoke can cause serious pollution to the surrounding environment, endangering human health and failing to meet environmental protection requirements.

Therefore, a good sealing device at the head and tail of the antimony smelting rotary furnace is a key factor in ensuring a stable and efficient smelting process, improving product quality and metal yield, reducing production costs, and protecting the environment.
