A high-efficiency hot blast stove

Abstract

The invention discloses a high-efficiency hot air furnace. The high-efficiency hot air furnace comprises a furnace body; a material outlet is formed in one side of the furnace body; checker bricks are arranged on the outer side of the furnace body; a heating body is arranged on one side of the checker bricks; one side of the heating body is connected with a furnace liner; a top plate is mounted at the top of the checker bricks; a material inlet is formed in the inner cavity of the top plate; the top of the top plate is connected with a top cover; the inner cavity of the furnace body is fixedly connected with a heater; a supporting plate is mounted at the bottom of the furnace body; leaking holes and an annular groove are formed in the inner cavity of the supporting plate; a filtering screen is arranged in the inner cavity of each leaking hole; a fan frame is mounted at the bottom of the furnace body; a fan is mounted in the inner cavity of the fan frame; and one side of the fan is connected with an air pipe. According to the high-efficiency hot air furnace, a heat insulating material is arranged on the outer side of the heating body, so that the heat in the hot air furnace does not lose easily; the use efficiency is effectively improved; the temperature in the furnace body can be effectively increased through the heating body, the furnace liner and the heater; coking in the air pipe caused by the problem of negative pressure is avoided; and the service life of the hot air furnace is greatly improved.

Description

technical field [0001] The invention relates to the technical field of smelting, in particular to a high-efficiency hot blast stove. Background technique [0002] As the name implies, a hot blast stove is a thermal equipment that integrates combustion and heat transfer processes to provide hot air flow for the process. Generally, there are two major types, namely, the intermittently working regenerative hot blast stove and the continuous heat exchange hot blast stove. Today, when the high-temperature ceramic heat exchange device is still immature, the intermittently working regenerative hot blast stove is still the mainstream product of the hot blast stove. In order to continuously provide hot air, the regenerative hot blast stove must at least have two hot blast stoves that work alternately. [0003] At present, when the existing hot air stoves on the market are in use, because there is no good heat preservation equipment in the furnace body, it is easy to lose the heat in ...

Problems solved by technology

[0003] At present, when the existing hot air stoves on the market are in use, because there is no good heat preservation equipment in the furnace body, it is easy to lose the heat in the furnace body, and the existing hot air fans are easy to cause coking in the hot air pipe during use. , which shortens the service life of the hot blast stove, and the existing hot blast stove is very inconvenient to clean, which brings a lot of trouble to the staff and reduces the work efficiency
