Description

Technical Field

[0001] This invention relates to the field of fused alumina brick preparation technology, specifically to an apparatus and method for preparing fused alumina-zirconia bricks. Background Technology

[0002] Fused zirconia-corundum bricks, as a special refractory material with important applications in many industrial fields, involve several key steps in their production process. The uniformity of raw material mixing plays a crucial role in the quality and performance of the final product.

[0003] The specific manufacturing process of fused zirconia corundum bricks is as follows: It mainly uses pure alumina powder and zircon sand in a specific ratio as the basic raw materials. The zircon sand contains about 65% zirconium oxide and about 34% silicon dioxide. These raw materials are put into an electric melting furnace and melted in a high-temperature environment. After the raw materials are fully melted, they are poured into a pre-prepared mold. After a period of natural cooling or a specific cooling process, a hard, high-performance white solid is finally formed – fused zirconia corundum bricks.

[0004] Before the actual production of fused zirconia-corundum bricks, there is an indispensable preparatory work, which is to fully mix all the raw materials used in the production. Only by ensuring that the raw materials are mixed evenly can the various components react fully during the fusion process, so that the performance indicators of the final product can meet the design requirements.

[0005] However, in terms of current production processes, existing mixing devices have certain limitations when mixing raw materials. Specifically, the position of the stirring element in the mixing device is fixed. This fixed stirring method will cause some areas to not be sufficiently and effectively stirred during actual operation, resulting in so-called "stirring dead zones". In these stirring dead zone areas, the mixing effect of raw materials is extremely poor, and it is difficult for raw materials of different components to be evenly distributed.

[0006] Therefore, the present invention provides an apparatus and method for preparing fused zirconia-corundum bricks to solve the above problems. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, the present invention provides an electrofused zirconia corundum brick preparation device to solve the problem of dead zones in the mixing device when the mixing components of the above-mentioned mixing device are mixing raw materials.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An apparatus for preparing fused zirconia-corundum bricks includes a mixing tank, a feeding hopper installed on the side wall of the mixing tank, and a mixing mechanism for stirring raw materials and a driving mechanism for driving the mixing mechanism inside the mixing tank. The mixing mechanism includes a support frame and a connecting block, with the connecting block slidably connected inside the support frame. Two extrusion shafts are symmetrically arranged on the connecting block. When the support frame rotates, the support frame, in conjunction with the connecting block, pushes the raw material to make it churn and flow. At the same time, the extrusion shafts rotate to crush the solids in the raw material.

The two first drive shafts extend into the interior of the corresponding side frames. A first toothed ring is installed on the outside of the first drive shaft, and a first toothed rack is installed on the inner wall of the side frame. The first toothed rack is meshed with the first toothed ring. When the connecting block slides along the extension trajectory of the first receiving groove, the first toothed ring can drive the extrusion shaft of the first drive shaft to rotate through the meshing transmission with the first toothed rack. At this time, the two extrusion shafts can extrude and crush the raw material in the gap.

[0010] Preferably, an outer sleeve is fitted around the second drive shaft, the outer sleeve is coaxially arranged with the second drive shaft, an inner shaft is fixed to the inner wall of the outer sleeve, the inner shaft is coaxially arranged with the second drive shaft, and the outer wall of the inner shaft abuts against the inner wall of the second drive shaft, and one end of the inner shaft is rotatably connected to the side wall of the connecting block. Side support shafts are fixed on both sides of the outer sleeve, and the same support ring is fixed between the three connecting frames on the same horizontal plane.

[0011] Preferably, the outer wall of the inner shaft is fixed with a linkage block, and the inner wall of the second drive shaft is provided with a connecting groove adapted to the linkage block. The linkage block is slidably connected to the inner wall of the connecting groove. The connecting groove is composed of a spiral groove and a straight groove. The spiral groove is away from the corresponding connecting frame, that is, the straight groove is close to the adjacent connecting frame, and the tail end of the spiral groove is connected to the head end of the straight groove.

[0012] Preferably, the support frame is provided with a sliding frame, the sliding frame is provided with a slide rail, and the side support shaft is slidably connected inside the slide rail. The slide rail is inclined, with the bottom end of the slide rail close to the support frame, that is, the top end of the slide rail away from the support frame.

[0013] Preferably, the top of the sliding frame is fixed with a lifting shaft, and the upper side of the lifting shaft is provided with a first annular disk and a second annular disk. The first annular disk is provided with a third limiting hole adapted to the lifting shaft, and the lifting shaft is slidably connected inside the corresponding third limiting hole. A U-shaped frame is installed on the top of the lifting shaft, and a sliding shaft is fixed inside the U-shaped frame. A slide rail is provided on the second annular disk.

[0014] Preferably, each of the connecting frames is provided with a support frame, and a second drive shaft is provided between the support frame and the connecting frame. A first limiting hole is opened on the side of the support frame facing the second drive shaft. One end of the second drive shaft is fixed on the inner wall of the first limiting hole, and the other end of the second drive shaft is fixed on one side wall of the support frame. A second limiting hole adapted to the second drive shaft is opened on the side of the connecting frame facing the support frame, and the outer wall of the second drive shaft is rotatably connected to the inner wall of the corresponding second limiting hole.

[0015] Preferably, the driving mechanism includes a lifting frame, and the top of the second annular disk is fixed to the bottom of the lifting frame. The inner wall of the lifting frame is rotatably connected to a third driving shaft. The inner wall of the first annular disk is fixed to the outer wall of the third driving shaft, and the inner walls of multiple support rings are all fixed to the outer wall of the third driving shaft. A driving source is installed on the top of the mixing tank. A rotating shaft is fixed to the output end of the driving source, and a connecting arm is fixed between the outer wall of the driving source and the lifting frame.

[0016] Preferably, a first support plate is fixed to the top of the lifting frame, a second support plate is provided on the upper side of the first support plate, and the second support plate is fixed to the inner wall of the lid. A T-shaped limiting block is fixed to the top of the first support plate, and a T-shaped limiting groove adapted to the T-shaped limiting block is opened at the bottom of the second support plate. The T-shaped limiting block is slidably connected inside the T-shaped limiting groove. A second toothed ring is installed on the top of the third drive shaft, and a second toothed rack is installed on the top of the second support plate. The second toothed rack is meshed with the second toothed ring.

[0017] Preferably, the support frame has a first receiving groove on both sides that is adapted to the rib wall of the connecting block, and the rib wall of the connecting block is slidably connected to the inner wall of the first receiving groove. The first receiving groove can limit the connecting block to maintain the stability of the connecting block.

[0018] A method for preparing fused zirconia-corundum bricks includes the following steps: Step 1: Feed the raw materials that need to be mixed into the mixing tank through the feed hopper; Step 2: The drive mechanism drives the mixing mechanism to stir and mix the raw materials inside the mixing tank, while the support frame rotates to push the raw materials and make them churn and flow. At the same time, the two extrusion shafts rotate to crush the solid raw materials that are blocking the gaps. Step 3: The mixed raw materials can be discharged through the outlet.

[0019] The beneficial effects of this invention are as follows: 1. The lifting frame and the first support plate are driven by the drive source to rotate around the second support plate, thereby driving the entire mixing mechanism to move synchronously around the inner wall of the mixing tank. This allows for comprehensive mixing of the raw materials in all areas of the mixing tank. At the same time, the guide plate at the bottom of the lifting frame has an arc-shaped surface. During the rotation of the lifting frame, the arc-shaped surface can guide the raw materials in the tank, guiding the raw materials at the bottom of the mixing tank to flow upward. This effectively avoids the problem of raw materials settling and accumulating at the bottom of the tank due to gravity, ensuring that all raw materials in the tank can be fully stirred and evenly mixed.

[0020] 2. The trapezoidal flow guide area, which is wide at the beginning and narrow at the end, is defined by the adjacent inclined support frames. As the raw material flows through, it is constrained by the gradually narrowing width of the area and is continuously squeezed, which accelerates the fusion of different components and improves the uniformity of raw material mixing.

[0021] 3. The connecting block slides inside the support frame, and the first toothed ring of the first drive shaft meshes with the first toothed rack on the inner wall of the side frame, thereby driving the extrusion shaft to rotate around its own axis. At the same time, as the support frame rotates, the raw material is pushed into the gap between the two extrusion shafts. The rotating extrusion shaft will fully extrude and crush the solid raw material in the gap, breaking large solid objects into fine particles, effectively reducing the volume of solid objects.

Detailed Implementation

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0025] Reference Appendix Figures 1-6 As shown, an apparatus for preparing fused zirconia-corundum bricks includes a mixing vessel 10 for stirring and mixing raw materials. The mixing vessel 10 includes a lid 101 and a vessel body 102 installed at the bottom of the lid 101. An inclined feed hopper 11 is installed on the outer wall of the vessel body 102, through which the raw materials can be poured into the interior of the mixing vessel 10 for stirring and mixing. The bottom of the vessel body 102 has a discharge port, through which the stirred and mixed raw materials can be discharged.

[0026] The mixing vessel 10 is equipped with a mixing mechanism 20, which is used to stir and mix the raw materials inside the mixing vessel 10 to facilitate subsequent processing of the raw materials.

[0027] The mixing mechanism 20 includes a mixing component 21, a first linkage component 22, and a second linkage component 23. The first linkage component 22, in conjunction with the second linkage component 23, can drive the mixing component 21 to stir the raw materials inside the mixing vessel 10, and can also crush the solids in the raw materials.

[0028] The mixing assembly 21 includes four vertically arranged support frame groups inside the mixing vessel 10. Each support frame group consists of three support frames 2101, and the three support frames 2101 in the support frame group are arranged in a ring inside the mixing vessel 10, that is, the three support frames 2101 in the support frame group are on the same horizontal plane. A connecting block 2102 is installed inside the support frame 2101. A first receiving groove 2103 adapted to the rib wall of the connecting block 2102 is opened on both sides of the support frame 2101. The rib wall of the connecting block 2102 is slidably connected to the inner wall of the first receiving groove 2103. The first receiving groove 2103 can limit the connecting block 2102 to maintain the stability of the connecting block 2102.

[0029] It should be noted that since the two adjacent support frames 2101 are both inclined, and the two adjacent support frames 2101 restrict a guide area in the shape of a trapezoid, that is, the width of the guide area gradually decreases from the beginning to the end, which can compress the raw material inside the guide area. When the raw material inside the guide area flows from the beginning to the end of the guide area, the raw material is continuously compressed to improve the mixing degree of the raw material.

[0030] Two extrusion shafts 2104 are symmetrically arranged on the connecting block 2102. There is a gap between the two extrusion shafts 2104, so that the raw material can flow through the gap. A second receiving groove adapted to the extrusion shafts 2104 is opened on the connecting block 2102, and the extrusion shafts 2104 are located inside the second receiving groove.

[0031] It should be noted that the two support frames 2101 that together form the flow guide area will rotate synchronously until they are parallel. During the rotation of the support frame 2101, the two extrusion shafts 2104 inside the support frame 2101 will rotate around its axis. The two extrusion shafts 2104 will crush the raw material in the gap to reduce the area of ​​the raw material.

[0032] Side frames 2106 are installed on both sides of the support frame 2101. First drive shafts 2107 are fixed at both ends of the extrusion shaft 2104. The two first drive shafts 2107 extend into the interior of the corresponding side frames 2106. A first toothed ring 2108 is installed on the outside of the first drive shaft 2107. A first rack 2109 is installed on the inner wall of the side frame 2106. The first rack 2109 is meshed with the first toothed ring 2108. When the connecting block 2102 slides along the extension trajectory of the first receiving groove 2103, the first toothed ring 2108 can drive the extrusion shaft 2104 of the first drive shaft 2107 to rotate through the meshing transmission with the first rack 2109. At this time, the two extrusion shafts 2104 can extrude and crush the raw material in the gap.

[0033] The first linkage component 22 includes multiple connecting frames 2201, and each connecting frame 2201 corresponds to a support frame 2101. A second drive shaft 2202 is provided between the support frame 2101 and the connecting frame 2201. A first limiting hole is provided on the side of the support frame 2101 facing the second drive shaft 2202. The first limiting hole is coaxially arranged with the second drive shaft 2202. One end of the second drive shaft 2202 is fixed on the inner wall of the first limiting hole, and the other end of the second drive shaft 2202 is fixed on one side wall of the support frame 2101. A second limiting hole adapted to the second drive shaft 2202 is provided on the side of the connecting frame 2201 facing the support frame 2101. The second drive shaft 2202 is coaxially arranged with the second limiting hole, and the outer wall of the second drive shaft 2202 is rotatably connected to the inner wall of the corresponding second limiting hole. The second limiting hole is used to limit the second drive shaft 2202 to maintain the stability of the support frame 2101.

[0034] An outer sleeve 2203 is sleeved on the outside of the second drive shaft 2202. The outer sleeve 2203 is coaxially arranged with the second drive shaft 2202. An inner shaft 2204 is fixed on the inner wall of the outer sleeve 2203. The inner shaft 2204 is coaxially arranged with the second drive shaft 2202, and the outer wall of the inner shaft 2204 abuts against the inner wall of the second drive shaft 2202. One end of the inner shaft 2204 is rotatably connected to the side wall of the connecting block 2102.

[0035] A linkage block 2205 is fixed on the outer wall of the inner shaft 2204, and a connecting groove 2206 adapted to the linkage block 2205 is opened on the inner wall of the second drive shaft 2202, and the linkage block 2205 is slidably connected to the inner wall of the connecting groove 2206.

[0036] It should be noted that the connecting groove 2206 is composed of a spiral groove and a straight groove. The spiral groove is far away from the corresponding connecting frame 2201, that is, the straight groove is close to the adjacent connecting frame 2201. The tail end of the spiral groove is connected to the head end of the straight groove. The initial position of the linkage block 2205 is located at the head end of the spiral groove. When the linkage block 2205 slides from the head end of the spiral groove to its tail end, the second drive shaft 2202 can drive the support frame 2101 to rotate, so that the support frame 2101, the connecting block 2102 and the extrusion shaft 2104 can churn the raw materials inside the mixing tank 10, thereby improving the mixing efficiency of the raw materials. At the same time, the inner shaft 2204 pushes the connecting block 2102 to slide inside the support frame 2101, while the first toothed ring 2108 and the first toothed rack 2109 drive the extrusion shaft 2104 to rotate, which can break up the solids blocking the gap.

[0037] Both sides of the outer sleeve 2203 are fixed with side support shafts 2207, and the three connecting frames 2201 on the same horizontal plane are fixed with the same support ring 2209 to support the connecting frames 2201 and maintain the stability of the connecting frames 2201.

[0038] The second linkage component 23 includes multiple sliding frames 2301, and each sliding frame 2301 corresponds to a support frame group. A slide rail 2302 is provided on the sliding frame 2301, and the side support shaft 2207 is slidably connected inside the slide rail 2302.

[0039] It should be noted that the slide rail 2302 is inclined, with the bottom end of the slide rail 2302 close to the support frame 2101, that is, the top end of the slide rail 2302 is far away from the support frame 2101. When the connecting frame 2201 moves down, the side support shaft 2207 can slide from the bottom end of the slide rail 2302 to its top end, thereby driving the outer sleeve 2203 to slide towards the support frame 2101.

[0040] A lifting shaft 2303 is fixed to the top of the sliding frame 2301. A first annular disk 2304 and a second annular disk 2305 are provided on the upper side of the lifting shaft 2303. A third limiting hole adapted to the lifting shaft 2303 is opened on the first annular disk 2304, and the lifting shaft 2303 is slidably connected to the interior of the corresponding third limiting hole. A U-shaped frame is installed on the top of the lifting shaft 2303. A sliding shaft 2307 is fixed inside the U-shaped frame. A slide 2308 is opened on the second annular disk 2305, and the slide 2308 is curved, that is, the slide 2308 has peaks and valleys, and the sliding shaft 2307 is slidably connected to the interior of the slide 2308.

[0041] The mixing vessel 10 is equipped with a drive mechanism 30, which is used to drive the mixing mechanism 20 to stir and mix the raw materials.

[0042] The drive mechanism 30 includes a lifting frame 31, with the top of the second annular disk 2305 fixed to the bottom of the lifting frame 31. A third drive shaft 32 is rotatably connected to the inner wall of the lifting frame 31, and the inner wall of the first annular disk 2304 is fixed to the outer wall of the third drive shaft 32. The third drive shaft 32 is coaxially arranged with multiple support rings 2209, and the inner walls of the multiple support rings 2209 are all fixed to the outer wall of the third drive shaft 32. A drive source 33 is installed on the top of the mixing tank 10, and a rotating shaft is fixed to the output end of the drive source 33. A connecting arm is fixed between the outer wall of the drive source 33 and the lifting frame 31. A first support disk 34 is fixed to the top of the lifting frame 31. A second support plate 35 is provided on the upper side of the first support plate 34 and is fixed on the inner wall of the lid 101. A T-shaped limiting block 36 is fixed on the top of the first support plate 34 and a T-shaped limiting groove 37 adapted to the T-shaped limiting block 36 is provided on the bottom of the second support plate 35. The T-shaped limiting block 36 is slidably connected inside the T-shaped limiting groove 37. The T-shaped limiting block 36 and the T-shaped limiting groove 37 are used to limit the first support plate 34 to maintain its stability. A second toothed ring 38 is installed on the top of the third drive shaft 32 and a second toothed rack 39 is installed on the top of the second support plate 35. The second toothed rack 39 is meshed with the second toothed ring 38.

[0043] In use, the raw materials are poured into the mixing tank 10 through the feed hopper 11. The drive source 33 is turned on, and the output end of the drive source 33 drives the rotating shaft to rotate around its axis. The rotating shaft drives the lifting frame 31 and the first support plate 34 to rotate at the bottom of the second support plate 35 through the connecting arm. At the same time, the T-shaped limiting block 36 slides inside the T-shaped limiting groove 37. At this time, the mixing mechanism 20 moves along the circumference of the second support plate 35, which can evenly stir and mix the raw materials inside the mixing tank 10, avoiding the problem of dead corners in the mixing. Since the bottom of the lifting frame 31 is fixed with a guide plate, and the guide plate has an arc surface, as the lifting frame 31 moves, the raw materials are guided upward by the arc surface of the guide plate, thereby preventing the raw materials from settling at the bottom of the mixing tank 10.

[0044] As the first support plate 34 rotates, the second gear ring 38, in conjunction with the second gear rack 39, drives the third drive shaft 32 to rotate around its axial direction. The third drive shaft 32, through the support ring 2209, drives the connecting frame 2201 to move around its axial direction. The raw material entering the guide area flows from the head end to the tail end. At this time, the raw material is squeezed by the two support frames 2101 and the connecting block 2102, which can improve the fusion efficiency.

[0045] During the rotation of the third drive shaft 32, the sliding shaft 2307 slides inside the slide rail 2308. When the sliding shaft 2307 slides from the peak to the valley of the slide rail 2308, the sliding shaft 2307 drives the lifting shaft 2303 to move downward through the U-shaped frame. The lifting shaft 2303 then drives the sliding frame 2301 to move downward. At this time, the side support shaft 2207 slides from the bottom to the top of the slide rail 2302. The side support shaft 2207 then drives the outer sleeve 2203 to slide on the surface of the second drive shaft 2202. The linkage block 2205 slides along the extension trajectory of the spiral groove. At this time, the second drive shaft 2202 drives the support frame 2101 to rotate. The two support frames 2101 that make up the flow guide area will rotate, thereby churning the raw material to improve the flow of the raw material.

[0046] Meanwhile, the inner shaft 2204 pushes the connecting block 2102 to slide inside the support frame 2101. At this time, the rib wall of the connecting block 2102 slides inside the first receiving groove 2103. The first toothed ring 2108, in conjunction with the first toothed rack 2109, drives the extrusion shaft 2104 of the first drive shaft 2107 to rotate. As the support frame 2101 rotates, the raw material is pushed to flow between the two extrusion shafts 2104. The two extrusion shafts 2104 rotate to break up the solids in the gap, thereby reducing the generation of solids in the raw material.

[0047] refer to Figures 1-6 As shown, a method for preparing fused zirconia-corundum bricks includes the following steps: Step 1: Feed the raw materials that need to be mixed into the mixing vessel 10 through the feed hopper 11; Step 2: The drive mechanism 30 drives the mixing mechanism 20 to stir and mix the raw materials inside the mixing tank 10, while the support frame 2101 rotates to tumble the raw materials. At the same time, the two extrusion shafts 2104 rotate to crush the solid raw materials blocking the gap. Step 3: The mixed raw materials can be discharged through the outlet.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments.
