Description

Technical Field

[0001] This utility model relates to the field of iron trough castable processing technology, and in particular to a mixing device for preparing high slag erosion refractory iron trough castable. Background Technology

[0002] Iron trough refractory material is the most important material for blast furnace tapping. During the application process, iron trough material faces the combined effects of high-temperature molten iron scouring and abrasion, slag erosion and penetration in molten iron, and thermal stress generated by periodic contact with molten iron and slag. In order to obtain iron trough material with a long service life, the material design must not only consider its high-temperature mechanical properties, but also take into account its slag resistance and high-temperature erosion resistance.

[0003] For example, the production process of anti-slag erosion iron ditch castable disclosed in Chinese patent application number CN202410956409.4 is as follows: by optimizing the particle size distribution of waste iron ditch castable, mullite, brown corundum, iron slag and copper slag, and the proportion of silicon carbide powder, alumina powder, clay, carbon-containing resin, boron oxide, modified graphite, metallic silicon powder and metallic aluminum powder, the bonding degree between the raw materials is increased. At high temperature, boron oxide dissolves into the mullite phase, increasing the aspect ratio of the mullite phase and forming an interlocking structure. Both improve the critical strength of castables at high temperatures. Modified graphite improves the fluidity and plasticity of particles in castables, thus improving the volume stability of castables at high temperatures. Carbon-containing resin replaces spherical asphalt to improve the strength and performance of materials. Iron slag refers to iron oxides produced in blast furnaces, which have the characteristics of high iron content, easy melting, and good refractoriness. Copper slag contains high levels of precious metal elements such as copper, lead, and zinc, and has good refractoriness and plasticity, thus improving the castable's resistance to slag erosion and molten iron scouring.

[0004] The production process of iron trough castable requires mixing the raw materials of the iron trough castable.

[0005] For example, Chinese patent application CN202121336782.8 discloses a casting and mixing trolley for iron trough material. Its specific content includes: a square base with wheels; a vertically mounted cylindrical mixing tank on the base; a bag-breaking device with a sharp tip above the mixing tank; the bag-breaking device includes four steel bars obliquely positioned at the edge of the mixing tank and converging above the center of the mixing tank to form a cone-shaped structure with a pointed tip; the steel bars are fixed to the edge of the mixing tank by welding; a conical cap with the pointed tip facing upwards is welded below the tip and welded to the steel bars via connecting rods. When raw material is broken at the tip, it falls from top to bottom into the mixing tank. At this time, the raw material flows to the cap, and the conical cap causes the raw material to scatter around the mixing tank. However, it still has the following problems:

[0006] The bagged raw materials are transported to the top, where the top punctures the bag, and the raw materials leak from the punctured part onto the cap. However, the raw material packaging bags still need to be manually transported to the top. Furthermore, when multiple raw materials of the iron trough castable are mixed, the above structure can only be used to add them one strip at a time. It can be seen that the above structure has low mixing efficiency for the raw materials of the iron trough castable. Utility Model Content

[0012] The feeding frame has multiple drainage grooves on one side for the raw materials to fall into. The upper end of the triangular block is equipped with a Z-shaped stop hook for limiting the packaging bag. A sharp needle is installed on one side of the Z-shaped stop hook.

[0013] The lower end of the feeding frame is equipped with a lifting assembly for limiting the feeding frame. The lifting assembly includes a lifting platform for supporting the feeding frame. An electric push rod is installed on one side of the lifting platform for pushing the feeding frame.

Motor 2 is started, and reciprocating screw 1, in conjunction with screw nut 1, controls the lifting platform to move the feeding frame upward. When the horizontal height of the feeding frame is higher than the feeding hopper, electric push rod 2 pushes the feeding frame towards the feeding hopper, so that the lower trough is at the upper end of the feeding hopper. Then, motor 3 is started, and reciprocating screw 2, in conjunction with screw nut 2, controls the push plate to move to the left, pushing multiple raw material packaging bags towards the feeding hopper. When the packaging bags come into contact with the cutting blade, they are cut by the cutting blade, and the raw materials inside the packaging bags fall into the feeding hopper through the lower trough. Through the swing of the limiting base plate, multiple raw materials fall into different areas of the mixing cylinder cavity, so as to facilitate the full mixing of multiple raw materials. This utility model can simultaneously feed and mix multiple raw materials, improving the mixing efficiency of iron trough castable raw materials. Attached Figure Description

Detailed Implementation

[0032] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0033] Please see Figures 1-7 This utility model provides a mixing device for preparing high slag erosion trough castable, including a mixing device 100, which includes a mixing cylinder 110. A feed pipe 111 is fixedly installed at the lower end of the mixing cylinder 110 to facilitate the conveying of the mixed raw materials.

[0034] The mixing drum 110 is equipped with a stirring rod 120 for stirring the raw materials. A motor 121 is installed at the upper end of the stirring rod 120 to control the rotation of the stirring rod 120. The motor 121 controls the rotation of the stirring rod 120, so that the stirring rod 120 stirs the various raw materials in the mixing drum 110, so that the various raw materials are fully mixed.

[0035] A feeding hopper 130 for guiding raw materials is installed at one end of the mixing device 100. Buffer inclined plates 131 for buffering the raw materials are fixedly installed on the inner walls of both sides of the feeding hopper 130. A limiting base plate 132 for guiding the raw materials is movably installed at the bottom of the feeding hopper 130, and the right side of the limiting base plate 132 is movably installed at the bottom right side of the feeding hopper 130 via a support. A wire rope 133 is installed on the left side of the limiting base plate 132. An electric push rod 134 is installed at one end to pull the limiting base plate 132 in conjunction with the wire rope 133. When the raw material falls into the mixing cylinder 110 through the feeding hopper 130, the left and right movement of the electric push rod 134 causes the wire rope 133 to pull the left side of the limiting base plate 132 simultaneously. The angle between the limiting base plate 132 and the bottom of the feeding hopper 130 changes, so that various raw materials fall into different areas of the inner cavity of the mixing cylinder 110 through the guidance of the limiting base plate 132.

[0036] One end of the support column 140 is equipped with a feeding device 200 for feeding raw materials into the upward hopper 130. The feeding device 200 includes a feeding frame 210 for facilitating the conveying of various raw materials. The lower end of the feeding frame 210 is equipped with a lifting component 220 for limiting the feeding frame 210.

[0037] A support column 140 is installed at one end of the mixing device 100. A reciprocating screw 141 is installed in the middle of the support column 140 to guide the feeding frame 210 in conjunction with the lifting assembly 220. A motor 142 is installed at the upper end of the reciprocating screw 141 to control its rotation. The lifting assembly 220 includes a lifting platform 221 to support the feeding frame 210. An electric push rod 223 is installed on the right side of the lifting platform 221 to push the feeding frame 210. A screw nut 222 is fixedly installed at the rear end of the lifting platform 221 to control its up and down movement in conjunction with the reciprocating screw 141. After the motor 142 is started, the reciprocating screw 141, in conjunction with the screw nut 222, controls the lifting platform 221 to move up and down, thereby driving the raw material on the feeding frame 210 upward.

[0038] Multiple triangular blocks 211 are fixedly installed on the left end of the feeding frame 210. A cutting blade 212 for cutting raw material packaging bags is fixedly installed on one side of the triangular block 211. Multiple lower drain grooves 213 for raw materials to fall are opened on the left side of the feeding frame 210. The lower drain grooves 213 are located between adjacent triangular blocks 211, so that after the cutting blade 212 cuts the raw material packaging bag, the raw materials on both sides of the cut point fall into the feeding hopper 130 through the lower drain grooves 213.

[0039] The upper end of the triangular block 211 is equipped with a Z-shaped stop hook 214 for limiting the packaging bag. A sharp needle 10 is installed on one side of the Z-shaped stop hook 214 to prevent the raw material packaging bag from falling off. The middle of the feeding frame 210 is equipped with a push plate 215 for pushing the packaging bag. A screw nut 216 is fixedly installed at the front end of one end of the push plate 215. A reciprocating screw 217 is installed in the middle of the screw nut 216 to control the push plate 215 to move left and right in coordination with the screw nut 216. A motor 3 218 is installed at the right end of the reciprocating screw 217. Through the cooperation of the reciprocating screw 217 and the screw nut 216, the push plate 215 can push the packaging bag to the left so that the packaging bag can be cut by the cutting blade 212. Then the raw material in the packaging bag falls into the mixing cylinder 110 through the feeding hopper 130 for mixing and stirring.

[0040] When raw materials need to be mixed and stirred, multiple raw material packaging bags are arranged from front to back on the feeding frame 210, with the push plate 215 positioned to the right of the raw material packaging bags. As motor 2 142 starts, the reciprocating screw 1 141, in conjunction with screw nut 222, controls the lifting platform 221 to move the feeding frame 210 upwards. When the horizontal height of the feeding frame 210 is higher than the feeding hopper 130, the electric push rod 223 pushes the feeding frame 210 towards the feeding hopper 130, so that the lower trough 213 is positioned at the upper end of the feeding hopper 130. Then, motor 3 is started. 218. The reciprocating screw 217, in conjunction with the screw nut 216, controls the push plate 215 to move to the left, pushing multiple raw material packaging bags towards the upper hopper 130. When the packaging bags come into contact with the cutting blade 212, they are cut by the cutting blade 212. The raw materials inside the packaging bags fall into the upper hopper 130 through the lower trough 213. The sharp needles 10 on the Z-shaped hook 214 prevent the packaging bags from falling off easily. Multiple raw materials fall into different areas of the mixing cylinder 110 through the swing of the limiting base plate 132, so that the multiple raw materials can be fully mixed.

[0041] After the raw materials are fed in, the electric push rod 223 controls the feeding frame 210 to reset, and the lifting assembly 220 is reset under the guidance of the reciprocating screw 141, so that multiple packaging bags can be removed.

[0042] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
