Calcining furnace device for preventing high-temperature gas from pushing furnace cover to cause heat loss

Abstract

The invention relates to the technical field of calcining furnaces, and discloses a calcining furnace device capable of preventing high-temperature gas from pushing a furnace cover to cause heat loss.The calcining furnace device comprises a furnace body and a top cover; a fixing block is fixedly connected to the top of the furnace body; a limiting rod is movably connected to the interior of the fixing block; and a fixed disc is fixedly connected to the left side of the limiting rod. According to the calcining furnace device for preventing the high-temperature gas from pushing the furnace cover to cause heat loss provided by the invention, a transverse rod is pulled upwards, a limiting block I and a limiting block II move into the top cover, the top cover can be separated from the furnacebody, the transverse rod is pressed downwards, the limiting block I and the limiting block II push the limiting rod to move outwards, and the top cover and the furnace body can be closed at the moment; and therefore, the effect of quickly opening and closing the furnace cover is achieved. The limiting rod is clamped at the tops of the limiting block I and the limiting block II under the action ofa spring I, so that the top cover cannot be pushed upwards from the bottom, and the effect of preventing heat loss caused by loosening of the furnace cover due to gas expansion is achieved.

Description

technical field [0001] The invention relates to the technical field of calcination furnaces, in particular to a calcination furnace device that avoids heat loss caused by high-temperature gas pushing a furnace cover. Background technique [0002] Calciner is a kind of thermal equipment for heat treatment of carbon raw materials at high temperature to improve the properties of raw materials. Equipment for iron making, recovery of rare metals, catalyst production, environmental improvement, and production of specialty chemicals. [0003] In order to avoid the temperature loss of the calciner, most of the existing calciners are equipped with a furnace cover at the feed inlet. However, during the use of the calciner, the internal temperature continues to rise, and the gas will expand when heated, pushing the furnace cover, making the furnace cover and furnace The body is separated, resulting in heat loss inside the furnace body, resulting in unnecessary waste of resources, and ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a calciner device that avoids heat loss caused by high-temperature gas pushing the furnace cover. It has the advantages of preventing heat loss caused by gas expansion and loose furnace cover and can quickly open and close the furnace cover. During the use of the calcination furnace, its internal temperature continues to rise, and the gas will push the furnace cover when it is heated, so that the furnace cover is separated from the furnace body, resulting in heat loss inside the furnace body, resulting in unnecessary waste of resources, and the existing charging The process is manually opened by the staff to feed the furnace cover. The opening and closing process is relatively slow, which will also cause the loss of heat in the furnace body.
