Description

Technical Field

[0001] This utility model relates to the field of electrofused zirconia-corundum brick production technology, and more specifically, to an electrofused zirconia-corundum brick rotary casting device. Background Technology

[0002] Fused zirconia-corundum bricks are white solids formed by melting pure alumina powder with zircon sand containing approximately 65% ​​zirconium oxide and 34% silicon dioxide in an electric furnace and then pouring the mixture into a mold to cool. They possess extremely high wear resistance, corrosion resistance, and high-temperature resistance, and are widely used in mining, metallurgy, chemical, and power industries. In actual production, a casting device is required to pour the molten solution into the mold. In practice, fused zirconia-corundum bricks have advantages such as simple operation, stable structure, and good casting effect.

[0003] The prior art discloses a casting structure for producing fused zirconia-corundum bricks, with announcement number CN215943320U. This utility model only has one discharge structure. When the discharge structure is blocked by the cooled solidified material, the casting operation needs to be stopped before the discharge structure can be disassembled and replaced. This method will affect the casting efficiency of this utility model. At the same time, the discharge structure has a high temperature because it is filled with hot melt solution. Without a cooling structure, waiting for it to cool down automatically before disassembly will consume a lot of time and reduce the practicality of this utility model.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a rotary casting device for fused zirconia-corundum bricks, which has the following advantages:

[0018] (1) This utility model employs a casting box, a liquid guide hopper, and an installation shaft. In actual use of the fused zirconia-corundum brick rotating casting device, the hot melt is first poured into the casting box through the feed hopper. Then, using the control panel, two sets of drive motors and a self-locking forward / reverse motor are activated. The output ends of the two drive motors can rotate two sets of stirring blades and two sets of spiral blades via two connecting shafts. The rotating stirring blades and spiral blades can agitate the hot solution. The output end of the self-locking forward / reverse motor drives the main gear to rotate. Since the main gear and driven gear mesh with each other, the rotating main gear can push the driven gear to rotate. The rotating driven gear can rotate the casting box via a set of installation shafts on the left side. When the front set of liquid guide hoppers moves downwards, the hot solution inside the casting box can be discharged through the front... The liquid is discharged from a set of guide hoppers and a set of outlet hoppers in front, eventually falling into a set of casting molds. When the set of outlet hoppers in front becomes blocked, the output end of the self-locking forward and reverse motor is rotated in reverse using the control panel. The driven gear rotating in reverse can cause the casting box to rotate in reverse through a set of mounting shafts on the left. When the set of guide hoppers in the rear moves down, the hot liquid inside the casting box can be discharged through the set of guide hoppers in the rear and a set of outlet hoppers in the rear, eventually falling into another set of casting molds. At this time, the set of outlet hoppers in front can be disassembled and replaced. By repeating the above operation, the two sets of outlet hoppers can be replaced alternately. Through the setting of the casting box, guide hoppers and mounting shafts, the discharge structure can be changed without stopping the casting operation, which improves the working efficiency of the rotary casting device for fused zirconia corundum bricks.

[0019] (2) This utility model adopts an annular cavity plate. According to the above operation, when a set of liquid outlet hoppers is blocked, the operator can open and close a set of first control valves, a set of second control valves, and a set of third control valves on the same side. Then, using the control panel, the pump and the refrigeration components on the same side can be operated. The flowing cold water can circulate through a set of first high-temperature resistant hoses, an annular cavity plate, a set of second high-temperature resistant hoses, and a set of cold water tanks on the same side. After the annular cavity plate on the same side has cooled down, the four sets of mounting screws and four sets of mounting nuts are engaged with each other. The operator can use his hand to unload two sets of mounting nuts on the same side counterclockwise. When the two sets of mounting nuts on the same side are separated from the two sets of mounting screws on the same side, a set of liquid outlet hoppers on the same side can be removed for cleaning. The cleaning of the other set of liquid outlet hoppers is the same as the operation. It can be seen that the annular cavity plate has a cooling structure and can quickly cool down the material outlet structure, which improves the practicality of the rotary casting device for fused zirconia corundum bricks.

[0036] In one embodiment, the control panel is electrically connected to two sets of drive motors 8 and a self-locking forward and reverse motor 13 via wires. The control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0037] In one embodiment, a base is mounted on the lower part of the concave frame 1.

[0038] Working principle:

[0039] In actual use of the fused zirconia-corundum brick rotary casting device, the molten molten metal is first poured into the casting box 2 through the feed hopper 27. Then, using the control panel, the two sets of drive motors 8 and the self-locking forward and reverse motors 13 are activated. The output ends of the two sets of drive motors 8 can rotate the two sets of stirring blades 10 and the two sets of spiral blades 11 through the two sets of connecting shafts 9. The rotating stirring blades 10 and spiral blades 11 can agitate the hot solution. The output end of the self-locking forward and reverse motors 13 drives the main gear 14 to rotate. Since the main gear 14 and the driven gear 15 mesh with each other, the rotating main gear 14 can push the driven gear 15 to rotate. The rotating driven gear 15 can be driven by the left and right sides. A set of mounting shafts 7 on the side rotates the casting box 2. When the front set of liquid guide hoppers 3 moves down, the hot solution inside the casting box 2 can be discharged through the front set of liquid guide hoppers 3 and the front set of liquid outlet hoppers 6, and will eventually fall into a set of casting molds. When the front set of liquid outlet hoppers 6 is blocked, the output end of the self-locking forward and reverse motor 13 is rotated in the opposite direction using the control panel. The driven gear 15 rotating in the opposite direction can cause the casting box 2 to rotate in the opposite direction through the set of mounting shafts 7 on the left. When the rear set of liquid guide hoppers 3 moves down, the hot solution inside the casting box 2 can be discharged through the rear set of liquid guide hoppers 3 and the rear set of liquid outlet hoppers 6, and will eventually fall into another set of casting molds. At this time, the front... The first set of liquid outlet hoppers 6 can be disassembled and replaced. Repeating the above operation allows for alternating replacement of two sets of liquid outlet hoppers 6. Through the casting box 2, guide hopper 3, and mounting shaft 7, the discharge structure can be replaced without stopping the casting process, improving the working efficiency of the rotary casting device for fused zirconia-corundum bricks. Simultaneously, according to the above operation, when one set of liquid outlet hoppers 6 is blocked, the operator can open and close the first control valve 21, the second control valve 22, and the third control valve 26 on the same side. Then, using the control panel, the pump 24 and the refrigeration components on the same side can be activated. The flowing cold water can circulate through the first high-temperature resistant hose 1 on the same side. 9. A set of annular cavity plates 5, a set of second high-temperature resistant hoses 20, and a set of cold water tanks 23 on the same side are provided. After the annular cavity plates 5 on the same side have cooled down, the four sets of mounting screws 17 and four sets of mounting nuts 18 are threaded together. The operator can manually remove the two sets of mounting nuts 18 on the same side counterclockwise. When the two sets of mounting nuts 18 on the same side are separated from the two sets of mounting screws 17 on the same side, the liquid outlet 6 on the same side can be removed for cleaning. The cleaning of the other set of liquid outlet 6 is carried out in the same way. It can be seen that the annular cavity plates 5 have a cooling structure and can quickly cool down the material discharge structure, which improves the practicality of the rotary casting device for fused zirconia corundum bricks.
