Kiln with high-pressure blast ultra-red radiation prevention system

Abstract

The invention relates to a kiln with a high pressure wind and anti infrared ray radiation system, which comprises a furnace body (2), a hearth (1) and a trolley (3), wherein, the trolley (3) is arranged in the hearth (1); angular frames (4) are sealed on the left and right side walls of the trolley (3); a battle plate (5) is downwardly arranged on the angular frame (4); two blast knives (7) are arranged portrait upward on the left and right shaft walls close to the furnace body (2) at the bottom of the hearth (1); a blast groove (6) is formed between the blast knife (7) and the shaft wall; the lower end of the battle plate (5) is positioned on the blast groove (6) and closely clung with the wall of the blast groove (6), and the wall is far from the shaft wall. The invention is characterized in that two high pressure positive blowers (9) are arranged behind the furnace body (2); an air outlet of the high pressure positive blower (9) is connected with an air inlet of a wind pipe (10); an air outlet of the wind pipe (10) is inserted into the blast grooves (6) on the left and right sides of the bottom of the hearth (1). The invention has the advantage that infrared ray from blaze produced by burning of frit within the hearth can be prevented from entering a gap between the trolley and the shaft wall or the bottom of the trolley, thus avoiding the burning off of the trolley.

Description

technical field [0001] The invention relates to a kiln, in particular to a kiln with a high-pressure wind protection system against infrared radiation. Mainly used for heating or heat treatment of cast steel etc. It belongs to the technical field of heating equipment. Background technique [0002] Before the present invention was made, the kilns in the past were generally made up of furnace body, furnace hearth, trolley and slide rail etc. In order to prevent the trolley from being burned out, the upper corner frame is usually enclosed on the left and right side walls of the trolley table, and the fire baffle is arranged downward on the corner frame, and the bottom of the furnace near the left and right furnace walls is installed vertically upward. Two sand wind knives. Even so, the trolley will burn out quickly, because the temperature in the furnace is as high as 1220-1250°C, and the infrared rays of the flame generated by the combustion of the burning materials in the ...

AI Technical Summary

Problems solved by technology

In order to solve the above problems, the general practice of trolley manufacturers is to replace the corner frames, fire baffles and sand wind knives on both sides of the trolley with high-temperature resistant steel, but even this cannot solve the fundamental problem, and the trolley is still used burn out
