Description

Technical Field

[0001] This utility model relates to the field of white fused alumina production technology, specifically a tilting furnace for white fused alumina production. Background Technology

[0002] White fused alumina is made from alumina through high-temperature smelting. It is white in color, slightly harder than brown fused alumina, and slightly less tough. Abrasives made from white fused alumina are suitable for grinding high-carbon steel, high-speed steel, and quenched steel. The production of white fused alumina requires a tilting furnace for smelting.

[0003] However, in the existing tilting furnace, during the tilting and rotating stage, there is no buffer structure at the bottom of the tilting furnace. As a result, the molten white corundum inside will surge in the tilting direction and spill out of the tilting furnace, which is not only dangerous but also wasteful. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tilting furnace for white fused alumina production. This solves the problem that in existing tilting furnaces, during the tilting and rotating stage, the lack of a buffer structure at the bottom causes the molten white fused alumina inside to surge in the tilting direction and spill out of the furnace, which is not only dangerous but also wasteful.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a tilting furnace for white fused alumina production, comprising a bottom plate and a support fixedly connected to its top, a drive assembly installed on the side wall of the support, a tilting furnace rotatably connected to the inner wall of the support via a rotating shaft, and a heating base fixedly connected to the bottom end of the tilting furnace, a rotating assembly installed at the bottom end of the heating base, and a buffer mechanism and a filtering mechanism respectively provided at the bottom and top ends of the support;

[0006] The buffer mechanism includes a crossbar fixed to the bracket. A pair of first vertical plates are fixed to the outer wall of the crossbar. A second vertical plate is installed on the inner side of the first vertical plate. The inner wall of the through hole of the pair of second vertical plates is slidably connected to the outer wall of the crossbar. A damping rubber sleeve and a spring are respectively sleeved in the middle and on both sides of the crossbar. The two ends of the damping rubber sleeve are connected to the second vertical plate. The two ends of the spring are respectively connected to the first vertical plate and the second vertical plate. A connecting component is installed at the top of the second vertical plate.

[0007] Preferably, the connecting assembly includes a connecting rod hinged to the second vertical plate via a pin, a rectangular block hinged to the top of the connecting rod via a pin, a horizontal plate fixed to the top of the rectangular block, and the outer walls of both ends of the horizontal plate slidably connected to the sliding groove of the bracket.

[0008] Preferably, the rotating assembly includes a pair of rollers that are attached to the bottom end of the heating base, the outer wall of the rollers being rotatably connected to a concave plate, and the bottom end of the concave plate being fixedly connected to a horizontal plate.

[0009] Preferably, the drive assembly includes a support plate fixedly connected to the side wall of the support frame, a reducer fixedly connected to the top of the support plate, the output end of the reducer being connected to the rotating shaft of the tilting furnace via a coupling, and a motor being connected to the input end of the reducer.

[0010] Preferably, the filtration mechanism includes a gas cooler and a housing fixed to the top of the support. The two ends of the gas cooler are respectively connected to a first pipe and a second pipe, and the end of the first pipe away from the gas cooler is connected to the interior of the housing. The bottom end of the second pipe passes through the support and is connected to a gas collection hood. The two pairs of grooves in the housing are respectively equipped with filter screens and filter layers.

[0011] Preferably, a fan is fixedly connected to the side wall of the housing, and the air inlet pipe of the fan is connected to the interior of the housing.

[0012] Beneficial effects

[0013] This utility model provides a tilting furnace for white corundum production, which has the following beneficial effects:

[0014] When it is necessary to pour out the molten white fused alumina material from the tilting furnace, the motor can be started. The motor, in conjunction with the reducer, drives the tilting furnace to rotate slowly. At this time, the heating base will squeeze the rollers, causing the rollers to move the horizontal plate through the concave plate. The horizontal plate then moves the connecting rod through the rectangular block. In this way, the connecting rod can drive the second vertical plate to move on the horizontal rod. The second vertical plate, together with the first vertical plate, will stretch the spring and squeeze the damping rubber sleeve. In this way, the elasticity of the spring and the damping rubber sleeve can buffer the tilting furnace above, making its rotation more stable. This also minimizes the risk of molten white fused alumina spilling out of the tilting furnace, thus increasing safety. Attached Figure Description

[0025] A groove is machined on the lower inner wall of the bracket 2 to limit the movement of the horizontal plate 5.

[0026] In this embodiment, the rotating assembly includes a pair of rollers 7 that are attached to the bottom of the heating base 4, and a concave plate 6 is rotatably connected to the outer wall of the rollers 7, and the bottom end of the concave plate 6 is fixedly connected to the horizontal plate 5.

[0027] When the heated base 4 presses against the rollers 7, the rollers 7 can also rotate to reduce friction.

[0028] In this embodiment, the driving assembly includes a support plate 15 fixedly connected to the side wall of the bracket 2, a reducer 16 fixedly connected to the top of the support plate 15, the output end of the reducer 16 being connected to the rotating shaft of the tilting furnace 3 via a coupling, and a motor 17 being connected to the input end of the reducer 16.

[0032] It is worth noting that the electrical structures and other components involved in this application can be selected according to the user's needs, as long as they meet the requirements of this application. At the same time, the corresponding control circuits and other components are all existing technologies, which can be fully implemented by those skilled in the art, so they will not be described in detail here.

[0033] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0034] Example: When this device is needed, the external motors and connecting lines of each electrical structure can be connected. Then, the white fused alumina raw material is heated through the heating base 4 and the tilting furnace 3. When it is necessary to pour out the molten white fused alumina raw material in the tilting furnace 3, the motor 17 can be started. The motor 17, together with the reducer 16, drives the tilting furnace 3 to rotate slowly. At this time, the heating base 4 will squeeze the roller 7, causing the roller 7 to move the horizontal plate 5 through the concave plate 6. The horizontal plate 5 then drives the connecting rod 11 to move through the rectangular block 12. In this way, the connecting rod 11 can drive the second vertical plate 10 to move on the horizontal bar 8. The second vertical plate 10, together with the first vertical plate 9, will stretch the spring 14 and squeeze the damping rubber sleeve 13. In this way, the elasticity of the spring 14 and the damping rubber sleeve 13 can buffer the tilting furnace 3 above, making it more stable when rotating. This also avoids the molten white fused alumina from spilling out of the tilting furnace 3 to the greatest extent, thus making it safer.

[0035] Simultaneously, the fan 25 is started, and the fumes generated during the processing of white corundum are drawn into the gas collection hood 21, then enter the gas cooler 18 through the second pipe 20. After being cooled, they enter the housing 22 through the first pipe 19, and are filtered through the filter screen 23 and the filter layer 24 in sequence. Finally, they are discharged through the fan 25, thus achieving the treatment of fumes.
