Description

An iron-making blast furnace tapping mechanism and its use method

Technical field

The present invention relates to the technical field of iron-making blast furnaces, and specifically relates to an iron-making blast furnace tapping mechanism and a method of using the iron-making blast furnace.

Background technique

The ironmaking blast furnace is a vertical blast furnace used for smelting molten iron. The blast furnace body is made of steel plate as the furnace shell, and the shell is lined with refractory bricks. The blast furnace body is divided into five parts from top to bottom: furnace throat, furnace body, furnace waist, furnace belly, and furnace hearth. Due to the advantages of blast furnace ironmaking with good technical and economic indicators, simple process, large production volume, high labor productivity, and low energy consumption, the iron produced by this method accounts for the vast majority of the world's total iron production. During blast furnace production, iron ore, coke, and slagging flux (limestone) are loaded from the top of the furnace, and preheated air is blown in from the tuyere located at the bottom of the furnace along the furnace circumference. At high temperatures, the carbon in the coke (some blast furnaces also inject auxiliary fuels such as pulverized coal, heavy oil, natural gas, etc.) burns with oxygen in the air to produce carbon monoxide, which removes the oxygen in the iron ore during the rise in the furnace. Sulfur and phosphorus are reduced to obtain iron. The smelted molten iron is released from the iron mouth.

Although a large amount of molten iron can be smelted through a blast furnace in the prior art, it is inevitable that there are still some shortcomings during installation and use. For example, the tap groove has a high error during installation in alignment with the tap hole, resulting in incorrect installation. Convenience problem, in order to avoid such problems, in view of this: Chinese patent CN113293248B discloses an ironmaking blast furnace tapping device, which includes a base, the blast furnace is installed on the base, and the blast furnace includes a tap hole arranged at the bottom. , the tapping device is arranged corresponding to the tap hole. The tapping device includes a supporting frame and a tapping groove fixed on the supporting frame. A connecting component is provided between the base and the supporting frame. The connecting component includes a side wall with the base. An integrally formed chute, one end of the support frame close to the base is integrally formed with a connecting plate, and the connecting plate is slidably connected to the chute. The chute plays a limiting role in the horizontal movement of the connecting plate, reducing the possibility that the tap trench does not correspond to the tap hole position, and at the same time improving the convenience of tap trench installation.

Although the above solves the problem of inaccuracies in the position of the tap hole and the tap hole, resulting in inconvenient installation of the tap hole, it does not avoid that it still has shortcomings in the actual use process, such as the installation of the tapping part. There is a lack of a slag fishing and filtering mechanism, so the traditional use of slag ditches to discharge slag causes the molten iron to flow with the slag, resulting in a large loss of molten iron. In order to avoid such problems, an ironmaking blast furnace is proposed. The tapping mechanism and its use method are used to solve existing problems.

The invention also discloses a method for tapping iron from an ironmaking blast furnace, which specifically includes the following steps:

S1. When in use, the molten iron is guided to the inside of the tap trough through the tap hole. When the molten iron flows along the tap trough, it will gradually come into contact with the slag blocking plate and be filtered and intercepted by the slag blocking plate. Because the slag blocking plate The interception height is only at the upper level of the molten iron, so the floating scum layer above the molten iron will be intercepted by the slag blocking plate, and the remaining molten iron will continue to flow along the bottom of the slag blocking plate;

S2. When intercepting scum, start the drive motor synchronously. After the drive motor is started, the drive motor will drive the reciprocating screw to rotate through the output shaft. When the reciprocating screw rotates, the thread sleeve on its surface will cooperate with the reciprocating screw thread and the guide slide. The limited cooperation between the rod and the guide sliding sleeve prompts the threaded sleeve to reciprocate left and right. The movement of the threaded sleeve drives the limit sleeve, the movable telescopic plate and the slag fishing orifice plate to move. During the movement of the slag fishing orifice plate, the fished scum will gradually be moved. Push it to the inclined surface of the guide frame until the scum falls into the inside of the slag aggregate inclined frame for the next process;

S3. When the reciprocating screw rotates to drive the thread sleeve to reciprocate, the reciprocating screw will also drive the second bevel gear to rotate. The rotation of the second bevel gear will mesh with the adjacent first bevel gear, and synchronously drive the rotating shaft through their mutual meshing. Rotation, the rotation of the rotating shaft will drive the crushing tool to crush the scum that falls into the inclined frame of the slag aggregate to prevent the scum from coagulating with each other;

The rotation of the rotating shaft will also drive the fixed circular plate to rotate, and the fixed circular plate drives the arc convex block to rotate. During the rotation of the arc convex block, it will reciprocate with the arc-shaped inclined block to form an extrusion fit, and the arc-shaped inclined block will be squeezed by extruding the arc-shaped inclined block. , prompting the annular hollow plate to drive the slag aggregate inclined frame to reciprocate and elastically screen up and down. The sifting motion of the slag aggregate inclined frame will accelerate the slag to fall into the slag temporary storage box for temporary storage;

S4. When the rotating shaft rotates, the rotating shaft will also drive the second driving sprocket to rotate. The rotation of the second driving sprocket will form a transmission cooperation with the driving chain and the first driving sprocket, and through its transmission cooperation, it will synchronously drive the rotating shaft to rotate. The rotation of the rotating shaft will drive the slag material transfer rack to rotate and agitate. The rotation and agitation of the slag material transfer rack will continuously agitate the scum that falls into the slag material temporary storage box and store it neatly and flatly, so as to avoid the formation of high piles easily when the slag material is stored at fixed points. , resulting in the problem of insufficient utilization of the internal space of the slag temporary storage box.

Preferably, several filter holes are provided on the side of the slag fishing orifice plate in S2. The filter holes can filter the molten iron for the slag fished out and reduce the loss of molten iron.

The collected scum must also be laid out in a regular manner to avoid fixed-point collection of scum, which may easily cause high piles of slag and cause temporary damage to the slag. The problem of insufficient utilization of the space inside the storage box.

(2) The tapping mechanism of the ironmaking blast furnace elastically sets a slag aggregate inclined frame between two adjacent installation support plates, and sets an annular hollow plate and an arc between the slag aggregate inclined frame and the rotating shaft. The shaped inclined block, fixed circular plate and arc convex block enable the slag material inside the inclined frame of the slag aggregate to be crushed through the cooperation of the annular hollow plate, arc inclined block, fixed circular plate and arc convex block. Cooperating with it, the inclined frame of slag aggregate can also be screened up and down to accelerate the slag unloading speed.

(3) The iron tapping mechanism of the ironmaking blast furnace is provided with a first return spring between the movable telescopic plate and the limit sleeve, so that the slag scooping orifice plate can closely contact the slope of the guide frame through the tension of the first return spring. Fitting is carried out to enhance the pushing effect of the slag scooping orifice plate on the slag material.

(4) The tapping mechanism of the ironmaking blast furnace is provided with a guide sliding rod and a guide sliding sleeve on the top of the slag blocking plate, and the guide sliding sleeve is connected to the threaded sleeve, so that the threaded sleeve can pass through the guide sliding rod during movement. It cooperates with the limit of the guide sliding sleeve to provide movement stability for the threaded sleeve.
