Description

Water tyre exhaust device for casting furnace lining of chromium metal smelting furnace
Technical Field
The utility model relates to the field of metal chromium smelting, in particular to a water tire exhaust device for a casting furnace lining of a metal chromium smelting furnace.
Background
When smelting chromium, in order to prevent the smelting furnace body from being burnt out by liquid metal at high temperature, a furnace lining is required to be manufactured on the inner side of the furnace body. The manufacturing method of the furnace lining mainly comprises the steps of building magnesia bricks in a furnace body to form the furnace lining and casting smelting slag to form the furnace lining, but the cost of building the magnesia bricks is high, so the mode of casting the smelting slag to form the furnace lining is mostly adopted.
When smelting slag is cast, the water tyre needs to be placed in a furnace body, and cooling water is continuously injected into the water tyre. Molten slag is injected between the furnace body and the water tyre, and the slag forms a furnace lining after being cooled. When the lining is cast, a large amount of steam is generated after the temperature of cooling water rises, and the existing water tyre is not provided with an exhaust port or provided with a steel pipe as the exhaust port. If the exhaust port is not arranged, the pressure in the water tire is increased, the circulation speed of cooling water in the water tire is reduced, the cooling effect is poor, and the water tire bursts when the pressure exceeds a threshold value. If a steel pipe is arranged as an exhaust port, corrosive high-temperature steam can permeate the whole plant, further corrode equipment and possibly scald operators. If the pipeline is used for guiding steam, a cooling device needs to be configured, the manufacturing cost is high, and the pipeline is not suitable for complex environments of plants.
Disclosure of Invention
The utility model aims to provide the water tyre exhaust device for the casting furnace lining of the metal chromium smelting furnace, which has low manufacturing cost and convenient use, can effectively guide steam, increase the cooling efficiency of the water tyre and avoid the burst of the water tyre.
The utility model is realized by the following steps:
the utility model provides a metal chromium smelting furnace casting water tyre exhaust apparatus for furnace lining, includes the water tyre, is provided with inlet tube and outlet pipe at the water tyre top, and its special character is: an n-shaped exhaust supporting pipe is arranged at the top of the water tyre, and the exhaust supporting pipe is sequentially connected with a multistage funnel-shaped condensation hopper; the two adjacent condensation hoppers are connected through a chain, and when the chain is completely straightened, the upper condensation hopper extends into the lower adjacent condensation hopper; the diameter of the air inlet of the upper condensation hopper is larger than that of the air inlet of the lower adjacent condensation hopper, and the volume of the upper condensation hopper is 1.3-1.5 times that of the lower adjacent condensation hopper; a drainage channel is arranged below the lowest condensation hopper.
Furthermore, the length of the upper condensing hopper extending into the lower adjacent condensing hopper is more than or equal to 8% of the height of the cone enclosed by the upper condensing hopper and less than or equal to 20% of the height of the cone enclosed by the upper condensing hopper; and the conical vertex angle formed by the enclosing of the condensation hopper is more than or equal to 45 degrees and less than or equal to 62 degrees so as to increase the steam pressure at the bottom of the condensation hopper and lead the steam to be condensed and liquefied quickly.
Furthermore, the number of the condensation hoppers is 5-9.
Furthermore, the exhaust end of the exhaust supporting tube is sleeved with a heat-resistant sealing sleeve and is in threaded connection with the condensation hopper, so that sealing is guaranteed, and steam is prevented from escaping.
Furthermore, the exhaust supporting tube, the chain and the condensation hopper are all made of white steel, so that steam corrosion is avoided, and the service life is prolonged.
The utility model has the beneficial effects that:
at water child top installation exhaust stay tube, play the effect of supporting the transition, fight through the multistage condensation of steam in the exhaust stay tube with the water child, it is not high to avoid water child internal pressure too big cooling water circulation efficiency in resulting in the water child, avoids water child internal pressure too big simultaneously to lead to the explosion. And through the cooling step by step of the multistage infundibulate condensation fill, its special shape setting can enough avoid steam to scatter and lead to equipment corruption and personnel to scald, can make the quick condensation liquefaction of steam again, low in cost. Through the chain connection, each position is conveniently pulled, the arrangement in a complex factory building environment is facilitated, and the use is convenient. By using the exhaust device, not only can the operation of staff be facilitated, but also the discharge of gas in the water tire can be accelerated, and potential safety hazards are avoided.
