Description

Flow bricks for metal smelting furnaces

technical field

The utility model relates to metal smelting equipment, in particular to a discharge device for a smelting furnace used for producing brass.

Background technique

In the current brass smelting and processing equipment, the submerged liquid discharge has basically been realized, as described in the patent No. 200620103968.8, a discharge device for metal smelting equipment: the inner cavity and outer cavity of the melting furnace are provided with refractory bricks with discharge holes , the discharge hole of the refractory brick is sealed and equipped with a plugging device, the bottom of the outer chamber of the melting furnace and the holding furnace run through, and a connected graphite sleeve connection device is installed, so that the discharge of copper water is controlled as a sealed submerged flow, which has the following characteristics Advantages: First, the copper water is not in contact with the air during discharge, basically removes the smoke and dust during discharge, reduces the pressure of the dust removal system, greatly improves the environmental pollution in the workshop, reduces smoke and dust emissions every year and reduces costs; second, copper and zinc burning The loss is significantly reduced, the energy consumption per unit of product is reduced by 15%, and the waste slag generated by the holding furnace is reduced by more than 50% compared with the original. , the discharge brick is prone to copper water condensation and freezing, or because the plug hole of the discharge brick needs to be replaced due to oxidation and wear after a period of use, which affects the continuous production of smelting and increases the cost. It takes 8 hours to replace a discharge brick Hours or so, when replacing the discharge brick, the whole set of smelting equipment needs to be in the state of step-down and heat preservation, which consumes a lot of electric energy.

Contents of the invention

The main purpose of the utility model is to solve the deficiencies of the prior art, thereby developing a discharge brick for metal smelting that does not take up maintenance time, has high production efficiency, low production cost, and saves power consumption.

The above-mentioned technical problems of the utility model are mainly solved by the following technical scheme: a discharge brick for metal smelting furnace, which is characterized in that two discharge bricks placed side by side are arranged in the inner cavity at the bottom of the melting furnace. Made of graphite, the discharge brick is connected with the holding furnace through the discharge hole; the discharge brick is provided with a horizontally arranged inlet hole, and the upper wall of the inlet hole is provided with a blocking hole, and the aperture of the blocking hole is smaller than the aperture of the prior art , which is conducive to blocking the flow, and is also provided with a vertical discharge hole, and a horizontal tube is used to connect the discharge hole and the blocking hole horizontally. The purpose of using double discharge bricks is: when one discharge brick needs to be replaced and repaired due to wear and tear, another discharge brick can be used, thus saving downtime due to maintenance and saving power consumption.

The technical scheme of the utility model can also be further improved,

Preferably, the horizontal tube is arranged obliquely, with an inclination angle of 5-10° relative to the horizontal line. That is to say, the horizontal pipe is inclined downward from the direction of the blocking flow hole to the direction of the discharge hole, and forms an inclination angle of 5-10° with the horizontal line, which is conducive to the outflow of copper liquid and will not produce effusion.

Preferably, the axis of the inlet hole and the outlet hole perpendicularly intersect.

Compared with the prior art, the present invention has the following advantages:

One is to ensure the continuous production of the melting furnace;

The second is to reduce the cost of replacing graphite discharge bricks;

The third is to save the electric furnace insulation electricity cost due to the replacement and maintenance of graphite discharge bricks.

Accompanying drawing 1 is a kind of structural front view of the utility model;

Accompanying drawing 2 is A-A sectional view of Fig. 1.

Detailed ways

The technical solution of the utility model is further specifically described below through the embodiments and in conjunction with the accompanying drawings.

Example:

The two discharge bricks 1 shown in Fig. 1 and Fig. 2 are made of graphite, arranged side by side in the inner cavity at the bottom of the smelting furnace, and communicate with the holding furnace through the discharge hole 13. The discharge brick 1 is provided with a horizontally arranged inlet hole 11, and the upper wall or upper end of the inlet hole is provided with a blocking hole 12, and there is a diameter-expanding slope 15 between the blocking hole 12 and the upper opening of the blocking flow, so that the blocking hole The aperture of orifice 12 is less than the aperture of prior art, helps blocking flow like this, is also provided with discharge hole 13 on the limit of inlet hole, and the axis of inlet hole and discharge hole perpendicularly intersects, and between discharge hole and blocking flow hole Interconnected with horizontal pipe 14, horizontal pipe 14 is the inclination of 5 degrees, so that copper water flows to the discharge hole along the inclined surface when it is convenient to discharge, and reduces the possibility that copper water condenses and freezes. Before smelting in the smelting furnace, the double discharge bricks are respectively plugged with stopper rods at the blocking position, the gap between the two discharge bricks 1 is filled with refractory material 2, the bottom of the discharge holes is connected with graphite diversion bricks, and then introduced into the holding furnace. When it is necessary to discharge, open a stopper, and the melt will flow from the smelting furnace into the holding furnace. When a relief brick needs to be replaced and maintained, the stopper rod on the other relief brick can be used to block the flow hole, thus avoiding the loss of production stoppage due to the replacement of the relief brick.
