[0005] The above patents and prior art have the following problems:

[0006] The current slag filler is made by combining slag and pig iron blocks, and has a short service life, so it needs to be replaced frequently, which affects production efficiency. When mixed with other ores and slag or other refractory materials, ores of different sizes and volumes will block each other when mixed with slag or other refractory materials, which will lead to uneven combination of ore and slag or other refractory materials. When the hardness of the ore material is low, ores of different volumes will collide with each other, causing the broken ore to disperse into the interior of the slag or other refractory materials, thereby affecting the subsequent use of the slag or other refractory materials and the molding quality of the slag filler.

[0041] Beneficial effects of the present invention:

[0042] 1. By rotating the rotating plate 1 and the rotating plate 2, the rotating plate 1 and the rotating plate 2 will rotate to the top of the side plate, so that the opening groove 1 and the opening groove 2 are engaged with the surface of the movable rod, so that the rotation of the rotating plate 1 and the rotating plate 2 will drive the side plate to rotate inside the tank body, and then the side plate, the rotating plate 1, the cover cavity 1, the rotating plate 2 and the cover cavity 2 are stirred through their height distribution and rotation relative to the tank body, thereby improving the mixing efficiency of the refractory coating slurry inside the tank body.

[0043] Second, during the rotation of the side plate, the reciprocating member will be started synchronously, so that the reciprocating member drives the dispersion swing plate to make up and down tilt reciprocating motion on the inner side of the side plate through the movable rod, so that the rotating liquid inside the tank body is subjected to the thrust of the up and down swing of the dispersion swing plate, thereby further improving the mixing and agitation degree of the refractory coating slurry inside the tank body and shortening the mixing time of the slurry.

[0044] 3. After the refractory coating slurry is added to the interior of the tank body, the pushing member is reset, which will cause the filter disc to push the refractory coating slurry to the bottom of the tank body, so that the slurry that meets the filter hole standards of the filter disc passes through the filter holes of the filter disc, and the downward movement of the filter disc will squeeze the solid particles inside the refractory coating slurry, so that large solid particles are squeezed and crushed, thereby facilitating the subsequent stirring and mixing of the refractory coating slurry. Of course, during the rotation of the side plate, rotating plate one, cover cavity one, rotating plate two and cover cavity two, the pushing member can also be periodically started, so that the pushing member can be reciprocatedly lifted to cause the filter disc to continuously squeeze the refractory coating slurry at the bottom thereof, so that the large particle agglomerated slurry inside thereof is continuously crushed and reduced, thereby further improving the processing efficiency and mixing effect of the refractory coating slurry.

[0045] Fourth, the pusher is lifted to drive the dispersion swing plate to rise along the guide column, and the rotating plate 1 and the rotating plate 2 are reset under the rotation of the motor inside the rotary pusher, thereby reducing the obstruction of the dispersion swing plate, and the magnesite to be coated is placed inside the enclosure at the top of the dispersion swing plate at the top, and then the reciprocating member is started to control the movable rod to reciprocate up and down, so that the movable rod pulls the dispersion swing plate and the rubber flexible material of the swing block through the chuck during the reciprocating motion, so that the dispersion swing plate is tilted and swung up and down on the outside of the bayonet plate, so that the magnesite in the enclosure inside the dispersion swing plate at the top rolls along the surface of the filter plate, and the magnesite of a small volume falls along the filter hole of the filter plate, so that the magnesite of the same volume remains inside the enclosure at the top, and the magnesite of a small volume falls into the inside of the lower enclosure, thereby completing the sorting of magnesite of different volumes, and reducing the mutual obstruction of magnesite of different volumes, which leads to uneven coating of magnesite and coating slurry.

[0046] 5. The motor in the rotary push member drives the round table to rotate, so that the opening slots 1 and 2 are rotated and clamped to the surface of the movable rod to complete the positioning, and then the cylinder in the rotary push member pushes the round table downward, so that the sleeve 1 drives the cover cavity 1 at its bottom through the connecting rod and the dispersion rod 1, and the cover cavity 2 connected to the cover cavity 1 through the synchronous plate and the dispersion rod 2 to be clamped to the top of the enclosure, and the protruding block is clamped to the top of the filter plate, so that the movement of the magnesite inside the enclosure is restricted, thereby reducing the mutual rolling and collision of the magnesite in the subsequent magnesite coating and mixing process, so that the magnesite is restricted and protected, and the up and down swinging of the dispersion swing plate can make the magnesite more flat on the surface of the filter plate, reducing the squeezing of the magnesite by the downward pressure of the protruding block.

[0047] 6. When the magnesite is confined in the space inside the protrusions, the enclosure and the filter plate, the pusher is reset to allow the magnesite in the space inside the protrusions, the enclosure and the filter plate to be immersed in the slurry. At this time, the motor in the rotary pusher is started to drive the dispersion swing plate to rotate in the slurry, so that the slurry is stirred and the slurry stratification phenomenon during the immersion process is reduced. During the rotation of the dispersion swing plate, the reciprocating member is started synchronously to drive the dispersion swing plate to swing up and down, thereby improving the contact efficiency between the magnesite on the top of the dispersion swing plate and the slurry, so that the magnesite is quickly covered with the slurry in protection, thereby improving the molding quality of the slag patch composed of magnesite and refractory slurry.

[0048] 7. When dispersion rod 1 pushes cover cavity 1 and cover cavity 2 to cover the enclosure plate and the top of the filter plate on the top of the dispersion swing plate, dispersion rod 1 is elastically connected to cover cavity 1 and cover cavity 2 through the soft column inside the bottom mounting cavity thereof, so that with the swing of the dispersion swing plate, the deformation cooperation of the soft column can make cover cavity 1 and cover cavity 2 always swing with the swing of the dispersion swing plate, so that the dispersion swing plate covers the top of the side plate, thereby providing full protection for the coating of magnesite.

[0049] 8. After the magnesite has completed the preset soaking time, the pusher will drive the dispersion swing plate to lift up, so as to facilitate the unloading of the magnesite on the top of the dispersion swing plate. The lifting of the dispersion swing plate will drive the filter plate at its bottom to rise, so that the filter plate can filter the used slurry and remove the broken magnesite inside, thereby ensuring the internal purity of the slurry.

DETAILED DESCRIPTION

[0065] Embodiment 1

[0066] A refractory long-acting slag patch includes: magnesite and a refractory coating slurry coated on the surface of the magnesite, wherein the refractory coating slurry is composed of the following proportions by weight:

[0067] Fused magnesia 40-60%, silica fume 4-10%, sodium hexametaphosphate 1-5%, saccharin 5-10% and bentonite 3-10%;

[0068] Among them, MgO in magnesite>45%; MgO in fused magnesia>96%; SiO2 in silicon powder>99%;

[0069] The weight percentage of water in the refractory coating slurry is 5-20%.

[0070] The traditional technology is to use pig iron blocks as slag patching materials to fill the furnace, which can only be used for 4 hours before needing to be replaced. The refractory long-lasting slag patching materials can be used for 8-12 hours before needing to be replaced and have lower costs, thus saving the cost of using the converter.

[0071] The experimental statistics are as follows:

[0072] From the usage, the refractory long-term slag patch has good adhesion, does not produce smoke and dust, the average slag patch time is 11.5 minutes, and there is no material collapse during the furnace shaking process. The usage is 3-4 bags (1.5t-2t) of slag patching. After 6 hours of slag patching, the slag patching material is still visible, as shown in Table 1;

[0073] Table 1 Statistics of slag supplement usage

[0074]

[0075] During this furnace repair trial, the main purpose was to repair the large surface in front of the furnace with slag, so the furnace test data of the large surface in front of the furnace was analyzed as follows Figure 1 During the slag filling test, the thickness of the front large surface of the converter showed an increasing trend, and the effect of slag filling the front large surface could meet the requirements.

[0076] Cost comparison:

[0077] The slag filler is mainly used to replace the pig iron block slag filler. A cost comparison of the two slag fillers is conducted. The high-performance slag filler reduces the cost by 0.42 yuan / t compared with the pig iron block slag filler, as shown in Table 2.

[0103] By starting the pusher 1012, the pusher 1012 pushes the connecting sleeve 1013, the round table 1021 and the ring table 103 to rise, so that the filter disc 205 is lifted out of the inside of the tank body 101, the top of the tank body 101 is opened, and the refractory coating slurry is poured into the inside of the tank body 101, and then the pusher 1012 is reset to start the motor in the rotary pusher 102, so that the motor in the rotary pusher 102 drives the round table 1021 and the connecting sleeve 1013 at the bottom of the round table 1021 to move upward. The connecting rod 201 rotates, and the rotation of the connecting rod 201 drives the rotating plate 1 2013 and the rotating plate 2 2017 as well as the sleeve 1 2012 and the sleeve 2 2019 to rotate along the guide column 1014. Of course, in order to improve the transmission effect of the rotating plate 1 2013 on the rotating plate 2 2017, a connecting rod extending downward can be added on the side of the rotating plate 1 2013 close to the tank body 101 to be fixedly connected to the outer side of the rotating plate 2 2017, and the connecting rod does not contact the fixed rod 2022.

[0104] The rotation of the rotating plate 1 2013 and the rotating plate 2017 will cause the rotating plate 1 2013 and the rotating plate 2017 to rotate to the top of the side plate 203, so that the opening groove 1 20131 and the opening groove 20171 are engaged with the surface of the movable rod 2021, so that the rotation of the rotating plate 1 2013 and the rotating plate 2017 will drive the side plate 203 to rotate inside the tank body 101, and then the side plate 203, the rotating plate 1 2013, the cover cavity 1 2014, the rotating plate 2 2017 and the cover cavity 2 2018 are distributed by their height and rotated and stirred relative to the tank body 101, thereby improving the mixing efficiency of the refractory coating slurry inside the tank body 101;

[0105] When the side plate 203 is rotating, the reciprocating member 202 will be started synchronously, so that the reciprocating member 202 drives the dispersion swing plate 206 to make a reciprocating motion of up and down tilt conversion on the inner side of the side plate 203 through the movable rod 2021. That is, the side of the dispersion swing plate 206 opposite to the bayonet plate 20312 is lifted upward along with the movable rod 2021, so that the side of the dispersion swing plate 206 opposite to the bayonet plate 20312 is higher than the bayonet plate 20312, so that the dispersion swing plate 206 forms an inclined surface. When the side of the dispersion swing plate 206 opposite to the bayonet plate 20312 moves downward with the movable rod 2021, the side of the dispersion swing plate 206 opposite to the bayonet plate 20312 is lower than the bayonet plate 20312, so that the dispersion swing plate 206 forms an inclined surface again, and the inclined surface formed by the dispersion swing plate 206 is always located inside the side plate 203, so that the rotating liquid inside the tank body 101 is thrusted by the up and down swing of the dispersion swing plate 206, thereby further improving the mixing and agitation degree of the refractory coating layer slurry inside the tank body 101 and shortening the mixing time of the slurry;

[0106] It should be noted that after the refractory coating slurry is added to the interior of the tank body 101, the pusher 1012 is reset, which will cause the filter disc 205 to push the refractory coating slurry to the bottom of the tank body 101, so that the slurry that meets the filter hole standard of the filter disc 205 passes through the filter holes of the filter disc 205, and the downward movement of the filter disc 205 will squeeze the solid particles inside the refractory coating slurry, so that large solid particles are squeezed and crushed, thereby facilitating the subsequent stirring and mixing of the refractory coating slurry. Of course, during the rotation of the side plate 203, the rotating plate 1 2013, the cover cavity 1 2014, the rotating plate 2 2017 and the cover cavity 2 2018, the pusher 1012 can also be periodically started, so that the pusher 1012 is lifted back and forth, so that the filter disc 205 continuously squeezes the refractory coating slurry at the bottom thereof, so that the large particle agglomerated slurry inside thereof is continuously crushed and reduced, thereby further improving the processing efficiency and mixing effect of the refractory coating slurry.

[0107] After the slurry is mixed for a predetermined time, the pusher 1012 is lifted, driving the dispersion swing plate 206 to rise along the guide column 1014, and the rotating plate 1 2013 and the rotating plate 2 2017 are reset under the rotation of the motor inside the rotary pusher 102, thereby reducing the obstruction of the dispersion swing plate 206. By placing the dolomite to be coated inside the enclosure 2061 on the top of the dispersion swing plate 206 at the top, and then starting the reciprocating member 202, the reciprocating member 202 controls the movable rod 2021 to reciprocate up and down, so that the movable rod 2021 pulls the dispersion swing plate 206 and the rubber flexible material of the swing block 2032 through the chuck 20211 during the reciprocating motion, so that the dispersion swing plate 206 moves up and down on the outside of the bayonet plate 20312. The tilted swing makes the magnesite in the enclosure 2061 inside the top dispersion swing plate 206 roll along the surface of the filter plate 2062, so that the small volume of magnesite falls along the filter holes of the filter plate 2062, so that the same volume of magnesite remains inside the top enclosure 2061, and the small volume of magnesite falls into the lower end enclosure 2061, thereby completing the sorting of magnesite of different volumes, reducing the mutual shielding of magnesite of different volumes, resulting in uneven combination and coating of magnesite and coating slurry. Of course, in order to allow the magnesite falling from the top to fully fall into the lower end enclosure 2061, the area of ​​the lower end enclosure 2061 and the filter plate 2062 can be made larger than the area of ​​the top enclosure 2061 and the filter plate 2062;

[0108] When the magnesite is sorted, the motor in the rotary pusher 102 drives the round table 1021 to rotate, so that the opening slot 1 20131 and the opening slot 2 20171 are rotated and connected to the surface of the movable rod 2021 to complete the positioning, and then the cylinder in the rotary pusher 102 pushes the round table 1021 to move downward, so that the sleeve 1 2012 drives the cover cavity 1 2014 at the bottom thereof through the connecting rod 201 and the dispersion rod 1 2011, and the cover cavity 1 2014 drives the synchronous plate 2015 and the dispersion rod 2 2011 to move the sleeve 1 2012 downward. The cover cavity 2018 connected with 16 is snapped onto the top of the enclosure 2061, so that the protruding block 20141 is snapped onto the top of the filter plate 2062, so that the movement of the magnesite inside the enclosure 2061 is restricted, thereby reducing the mutual rolling and collision of the magnesite during the subsequent magnesite coating and mixing process, so that the magnesite is restricted and protected, and the up and down swinging of the dispersion swing plate 206 can make the magnesite spread more flat on the surface of the filter plate 2062, reducing the squeezing of the magnesite by the protruding block 20141 during the downward pressure.

[0109] It should be noted that in order to reduce the wear of magnesite, the material of the protrusion 20141 is preferably a flexible rubber material.

[0110] Then, when the magnesite is confined in the space inside the protruding block 20141, the enclosing plate 2061 and the filter plate 2062, the pusher 1012 is reset, so that the magnesite in the space inside the protruding block 20141, the enclosing plate 2061 and the filter plate 2062 is soaked into the slurry. At this time, the motor in the rotary pusher 102 is started, so that the motor in the rotary pusher 102 drives the dispersion swing plate 206 to rotate in the slurry, so that the slurry is stirred, and the slurry stratification phenomenon during the soaking process is reduced. During the rotation of the dispersion swing plate 206, the reciprocating member 202 is synchronously started, so that the reciprocating member 202 drives the dispersion swing plate 206 to swing up and down, thereby improving the contact efficiency between the magnesite on the top of the dispersion swing plate 206 and the slurry, so that the magnesite is quickly coated with the slurry during protection, and the molding quality of the slag patch composed of the magnesite and the refractory slurry is improved.

[0111] It should be noted that when the dispersion rod 1 2011 pushes the cover cavity 1 2014 and the cover cavity 2018 to cover the top of the enclosure 2061 and the filter plate 2062 on the top of the dispersion swing plate 206, the dispersion rod 1 2011 is elastically connected to the cover cavity 1 2014 and the cover cavity 2018 through the soft column 20112 inside the bottom mounting cavity 20111, so that as the dispersion swing plate 206 swings, the deformation of the soft column 20112 can make the cover cavity 1 2014 and the cover cavity 2018 18 always follows the swing of the dispersion swing plate 206, so that the dispersion swing plate 206 covers the top of the side plate 203, thereby providing full protection for the coating of the dolomite. Of course, the dispersion swing plate 206 and the bayonet plate 20312, the dispersion rod 1 2011 and the cover cavity 1 2014, and the dispersion rod 2016 and the cover cavity 2 2018 can also be hinged together, and the cover cavity 1 2014 and the cover cavity 2 2018 can also be always located on the top of the dispersion swing plate 206 as it swings.

[0112] After the magnesite has completed the preset soaking time, the pusher 1012 will drive the dispersion swing plate 206 to lift up, so as to facilitate the unloading of the magnesite on the top of the dispersion swing plate 206. The lifting of the dispersion swing plate 206 will drive the filter plate 205 at its bottom to rise, so that the filter plate 205 can filter the used slurry and remove the broken magnesite inside, thereby ensuring the internal purity of the slurry.
