Abstract

The invention provides a waste heat collection device for the feed end of an ultra-high temperature shaft kiln. In this technical proposal, a shell for heat collection is added at the port of the feed pipe of the conventional shaft kiln, and the heat radiating upward from the port is eliminated. The heat plays the role of blocking and collecting. The invention covers the outer periphery of the shell with a heat insulation layer, which can maintain the heat in the shell and effectively improve the recovery rate of waste heat; The wind is guided into the shell, and then transported to the outside through the air duct, which helps to alleviate the problem of material dust blocking. The feed hopper located at the upper end cover is used to add materials into the shaft kiln, and the large and small structure of the feed hopper also helps to alleviate heat loss. The temperature sensor located on the end cover can monitor the internal temperature of the shell, and can cooperate with the control system to control the fan speed according to the temperature. The invention has outstanding innovation and remarkable technical effect.

Description

technical field [0001] The invention relates to the technical field of supporting devices for a high-temperature shaft kiln, in particular to a waste heat collection device used at the feed end of an ultra-high-temperature shaft kiln. Background technique [0002] Shaft kiln refers to a vertical continuous kiln consisting of a steel shell with a vertical axis and a refractory brick lining, used for firing bulk bulk materials. Usually liquid or solid fuel is used, and the thermal efficiency is higher than that of tunnel kiln. It is widely used in the domestic refractory industry at present. [0003] Because the internal temperature of the shaft kiln is very high, it will naturally radiate heat to the outer periphery. This heat dissipation effect is especially obvious at the open feed port. If the heat is not collected, it will waste energy on the one hand and cause The temperature of the feed port is too high, which will affect the operating state and service life of the sur...
