[0002] Metallurgical furnace construction refers to the construction of metallurgical furnaces. The quality of metallurgical furnace construction directly affects the service life of the furnace and the thermal process, thus affecting the output and quality of the product.

[0003] The siphon phenomenon is based on the principle of pressure difference. In a closed container, the liquids have the same height and the same pressure. The siphon tube is filled with water, without air, the water level at the incoming end is high, and the outlet is closed with a palm or other object. At this time, the pressure in the tube is equal everywhere.

[0004] In order to meet the market demand, the existing siphon slag discharge devices are generally optimized in terms of how to discharge the slag better and how to make it more convenient for users to use them, but whether the slag can be blocked well is often ignored. Secondly, the existing siphon slag discharge devices have the advantages of better slag discharge and more convenient use by users, but have certain limitations. During normal slag discharge, the receiving items cannot block the slag well when they are full, causing the slag to dump, thereby causing environmental pollution. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See attached Figure 1-6 ;

[0028] Example 1

[0029] A siphon slag discharge device for a metallurgical furnace comprises a siphon device 1 for slag discharge, the upper end of the siphon device 1 is connected with a discharge pipe 2, an observation port 3 is fixedly installed on the outer surface of the siphon device 1 opposite to the discharge pipe, a flip-type blocking assembly is installed at the inlet end of the discharge pipe 2, the blocking assembly comprises a circular plate 4 matched with the inner wall of the discharge pipe 2, a positioning column 5 is rotatably connected at the bottom of the circular plate 4, the positioning column 5 is embedded in the inner wall of the bottom of the inlet end of the discharge pipe 2, a rotating column 6 is fixedly installed on the top of the circular plate 4, the rotating column 6 penetrates the discharge pipe 2 and extends to the outside, and a rotating handle 7 for convenient rotation is installed at the protruding end. The power source of the entire blocking assembly is realized by rotating the rotating handle 7 by manpower, because the force can be transmitted, and the rotating column 6 is driven to rotate while rotating the rotating handle 7, so that the circular plate 4 can be driven to rotate inside the discharge pipe 2, thereby realizing the blocking of the discharge pipe 2, and when cleaning is needed, it is only necessary to rotate the rotating handle 7 in the opposite direction, so that quick cleaning can be achieved.

[0030] Furthermore, a sealing block 8 is fixedly installed on the outer surface of the circular plate 4, and the outer surface of the sealing block 8 is arc-shaped. By setting the sealing block 9, the setting of the sealing block 8 can achieve a better sealing effect. A positioning member is provided on the rotating handle 7, and the positioning member includes a threaded rod 11. The threaded rod 11 is connected and matched with a threaded through hole 10 provided at the edge of the rotating handle 7. The bottom of the threaded rod 11 is used in conjunction with the outer surface of the discharge pipe 2. A rotating block 12 is fixedly installed on the top of the threaded rod 11. A cross groove 13 is provided on the top of the rotating block 12, so that the rotating effect of the rotating handle 7 can be better. The cross groove 13 is located in the middle of the top of the rotating block 12.

[0031] The power source of the entire positioning component is realized by rotating the rotating block 12 by human power. Since the force can be transmitted, the threaded rod 11 is driven to rotate inside the threaded through hole 10 while rotating the rotating block 12, so that the threaded rod 11 and the outer surface of the discharge pipe 2 can be squeezed (if better limiting is achieved, vertically arranged teeth can be distributed at the bottom end of the threaded rod, and a gear guided by the teeth for limiting the position is fixed on the outer surface of the discharge pipe 2. When the threaded rod is lowered, the teeth and the gear are clamped to achieve limiting), thereby realizing the positioning of the rotating handle 7 and achieving a better blocking effect.

[0032] Embodiment 2:

[0033] This embodiment is an improvement made on the basis of embodiment 1, in which a plugging component for sealing and plugging the discharge pipe is installed at the outlet end of the discharge pipe 2;

[0034] The blocking assembly includes a circular stopper 14, the front end of which is a stepped structure, and the inner wall of the outlet end of the discharge pipe is provided with a step that cooperates with the circular stopper 14, and a cavity 15 is provided inside the circular stopper 14 behind the step, and two moving blocks 16 that move synchronously with each other are slidably connected inside the cavity 15, and are symmetrically arranged along the vertical center axis of the circular stopper 14, and an extrusion spring 17 is fixedly installed between the moving blocks 16, and a pulling handle 18 is fixedly installed on the right side of the moving block 16, and the right side of the pulling handle 18 passes through the strip through hole 20 provided on the circular stopper 14 and extends out of the circular stopper 14, and an extrusion block 19 that cooperates with the inner wall of the discharge pipe 2 is fixedly installed on the end of the moving block 16 away from the extrusion spring 17; the outer surface of the extrusion block 19 is provided with an anti-skid groove 21, and the number of the anti-skid grooves 21 is multiple and evenly distributed.

[0035] When in use, the handle 18 is moved by human power, and the moving block 16 is driven to move inward while moving, and a deformation force is given to the extrusion spring 17, so that the extrusion block 19 can be pulled into the interior of the cavity 15, thereby realizing the cooperation between the circular stopper 14 and the inside of the discharge pipe 2. After the cooperation is completed, since the force is mutual, the extrusion spring 17 also gives the extrusion block 19 the same reaction force, so that it can be used in cooperation with the inner wall of the discharge pipe 2, realize the sealing of the inside of the discharge pipe 2, and prevent internal rust.

[0036] The outer end face of the circular stopper 14 is provided with two strip-shaped through holes 20 connected to the cavity, and symmetrically arranged along the transverse central axis of the circular stopper 14, and the pull handle 18 is guided and moved in the strip-shaped through hole 20. This not only limits the position of the pull handle 18, but also makes the movement trajectory of the pull handle 18 more stable. A protective block 9 is provided on the outer wall of the circular stopper 14 between the stage of the circular stopper 14 and the inner side of the extrusion block, which is sealed with the inner wall of the discharge pipe 2. The provision of the protective block 9 can make the sealing effect of the circular stopper 14 better.

[0037] The working principle of the siphon slag discharge device of the metallurgical furnace is as follows: first, the power source of the entire blocking assembly is realized by rotating the rotating handle 7 manually. Since force can be transmitted, the rotating column 6 is driven to rotate while rotating the rotating handle 7, so that the circular plate 4 can be driven to rotate inside the discharge pipe 2, thereby realizing the blocking of the discharge pipe 2. At the same time, when cleaning is needed, it is only necessary to rotate the rotating handle 7 in the opposite direction, so that rapid cleaning can be realized; secondly, when in use, the pulling handle 18 is manually driven to move, and the moving block 16 is driven to move inwardly while moving, and a deformation force is given to the extrusion spring 17, so that the extrusion block 19 can be pulled into the interior of the cavity 15, thereby realizing the coordinated use of the circular stopper 14 and the interior of the discharge pipe 2. After the coordination is completed, since the force is mutual, the extrusion spring 17 also gives the extrusion block 19 the same reaction force, so that the coordination use with the inner wall of the discharge pipe 2 can be realized, and the sealing of the interior of the discharge pipe 2 is realized to prevent internal rust.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0039] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
