[0002] A bell type kiln is a thermal equipment with a bell-shaped kiln body that can be lifted and inverted for intermittent production. It is mainly used for firing small batches of high-grade refractory products. The bell type kiln used for sintering manganese-zinc ferrite cores needs to be used with a cooler.

[0003] The existing bell kiln cooler is used to pass high-temperature gas into the cooling tube, and then fill water around the cooling tube to cool the high-temperature gas. In the cooling process of the above method, since the impurity components of the raw materials in the bell kiln volatilize during the sintering process, these volatiles are deposited in the thin cooling tube with the high-temperature gas and gradually block the pipeline. The gas flow to be cooled gradually decreases, which hinders the cooling speed and requires a longer cooling time. Therefore, a new bell kiln cooler is urgently needed to solve the above problems.

[0008] Furthermore, the water inlet pipe and the water outlet pipe are both welded to the upper end of the tank body, and connecting flanges are reserved on the water inlet pipe and the water outlet pipe.
