Description

A basalt fiber melting furnace that can be quickly inspected and repaired Technical Field

[0001] This utility model relates to the field of basalt fiber production equipment, and in particular to a basalt fiber melting furnace that can be quickly inspected and repaired. Background Technology

[0002] The basalt fiber melting furnace is the core equipment for producing continuous basalt fiber. Existing technologies generally adopt an integrated structural design, where the feed channel and the working unit are fixedly connected. Although this structure simplifies the manufacturing process, in actual use, when the spinneret needs to be repaired or replaced, the entire furnace must be shut down and cooled, resulting in a significant reduction in production efficiency and a long maintenance time (approximately 4-6 hours) for each repair. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a basalt fiber furnace that can be quickly repaired, thus solving the technical problem that the repair or replacement of the basalt fiber furnace's sprue plate is time-consuming.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A basalt fiber melting furnace capable of rapid maintenance includes: a feed channel; a working unit disposed downstream of the feed channel for receiving molten metal from the feed channel; a flow guiding device connecting the feed channel and the working unit for guiding the molten metal from the feed channel to the working unit; a side wall disposed on the side of the working unit near the flow guiding device; a high-temperature sealing element disposed on the upper end of the side wall; and a lifting mechanism drivenly connected to the working unit, capable of driving the working unit upward so that the upper end of the side wall seals against the bottom of the flow guiding device.

[0006] This invention significantly improves the maintenance efficiency and sealing reliability of basalt fiber melting furnaces by separating the material channel and the working unit and adopting a lifting sealing structure. Specifically, when the working unit needs maintenance or replacement of the perforated plate, the working unit can be moved out independently for maintenance, avoiding a complete shutdown. When installing the working unit, one side wall of the working unit is moved below the flow guiding device, and then the upper end can be tightly connected to the flow guiding device under the action of the lifting mechanism, ensuring the reliability of the seal.

[0007] Optionally, the basalt fiber melting furnace further includes: a perforated plate, detachably disposed at the bottom of the working unit; the perforated plate is connected to a power source via a conductive component; the power source is disposed on the outer wall of the material channel adjacent to the working unit.

[0008] Optionally, an installation groove is provided on the upper surface of the side wall, and the high-temperature seal includes a high-temperature pad, which is disposed in the installation groove.

[0009] Optionally, the high-temperature seal further includes an elastic element, and the high-temperature pad is connected to the mounting groove through the elastic element.

[0010] Optionally, the high-temperature seal further includes a connecting plate, the high-temperature pad is disposed on the upper surface of the connecting plate, and the lower surface of the connecting plate is connected to the mounting groove by an elastic element.

[0011] Optionally, the high-temperature pad adopts a multi-layer composite structure.

[0012] Optionally, a positioning block is provided at the bottom of the flow guiding device; the mounting groove is opened on one side of the side wall, and a guide portion is formed on one side of the mounting groove. The guide portion is located on one side of the positioning block, and the high-temperature seal is located below the positioning block. When the lifting mechanism moves the working unit upward, the upper end of the guide portion and the high-temperature pad respectively abut against the bottom of the flow guiding device and the bottom of the positioning block. By adding a positioning block at the bottom of the flow guiding device, on the one hand, the cooperation between the guide portion and the positioning block allows the working unit to move to a preset designated position, ensuring consistency between the side wall and the flow guiding groove. This eliminates the need for repeated position calibration when the working unit is reset, further reducing maintenance time. On the other hand, the upper end of the guide portion and the high-temperature pad abut against the bottom of the flow guiding device and the bottom of the positioning block respectively to form a double seal, further providing a reliable sealing effect. Simultaneously, the cooperation between the guide rail and the movable base makes the movement of the working unit simple and convenient.

[0013] Optionally, the basalt fiber melting furnace further includes: a support platform, which is movably mounted on one side of the material channel via a movable guide structure; the movable guide structure includes a movable base for driving the support platform and the working unit mounted on the support platform to move horizontally; and a lifting mechanism mounted on the movable base, the output end of which is driven to the support platform for driving the support platform and the working unit to move vertically.

[0014] Optionally, the movable guide structure may further include a guide rail adapted to the rollers of the movable base.

[0015] Optionally, the basalt fiber furnace may also include a limiting component for restricting the movement of the rollers.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model significantly improves the maintenance efficiency and sealing reliability of basalt fiber melting furnaces by separating the material channel and the working unit and adopting a lifting sealing structure. Specifically, when the working unit needs to be inspected and the perforated plate replaced, the working unit can be moved out independently for inspection, avoiding a complete shutdown; when installing the working unit, one side wall of the working unit is moved to below the flow guiding device, and then the upper end can be tightly connected to the flow guiding device under the action of the lifting mechanism, ensuring the reliability of the seal.

[0018] 2. By adding a positioning block at the bottom of the flow guiding device, on the one hand, the cooperation between the guide part and the positioning block allows the working unit to be easily moved to the preset designated position, ensuring consistent fit between the side wall and the flow guiding channel. This eliminates the need for repeated position calibration when resetting the working unit, further reducing maintenance time. On the other hand, the upper end of the guide part and the high-temperature pad abut against the bottom of the flow guiding device and the bottom of the positioning block respectively, forming a double seal and providing a more reliable sealing effect. Simultaneously, the cooperation between the guide rail and the movable base makes the movement of the working unit simple and convenient. Attached Figure Description

Of course, these are merely examples and are not intended to limit the embodiments of this utility model application. Furthermore, reference numerals and / or reference letters may be repeated in different examples of the embodiments of this utility model application; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various implementations and / or arrangements discussed.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] As shown in Figures 1-3, this utility model application provides a basalt fiber melting furnace that can be quickly repaired, including: a material channel 1, a working unit 2, a flow guiding device 3, a side wall 4, a high-temperature sealing component 5, and a lifting mechanism 6.

[0031] The working unit 2 is located downstream of the material channel 1 and is used to receive the molten liquid from the material channel 1.

[0032] The flow guiding device 3 connects the material channel 1 and the working unit 2, and is used to guide the molten liquid from the material channel 1 to the working unit 2.

[0033] The side wall 4 is vertically fixed to the side of the working unit 2 near the flow guiding device 3, and the high-temperature sealing element 5 is set on the upper end of the side wall 4.

[0034] The lifting mechanism 6 is driven and connected to the working unit 2. In use, the lifting mechanism 6 drives the working unit 2 to move vertically. When the working unit 2 moves upward, the upper end of the side wall 4 forms a dynamic seal with the bottom of the guide device 3 through the high-temperature seal 5. By setting the material channel 1 and the working unit 2 separately, when the working unit needs to be repaired, the material channel 1 is stopped from discharging material, and then the working unit 2 is moved out for repair. When installing the working unit 2, the side wall 4 on one side of the working unit 2 is moved to below the guide device 3. Then, driven by the lifting mechanism 6, the high-temperature seal 5 at the upper end of the side wall 4 can be tightly connected with the guide device 3 to ensure the reliability of the seal. The operation process is simple and quick.

[0035] Specifically,

[0036] A detachable perforated plate 7 is installed at the bottom of the working unit 2. The perforated plate 7 is connected to an external power supply 9 via a conductive component 8. Optionally, the conductive component 8 can be a conductive plate, and the external power supply can be a transformer. The transformer can be mounted on the outer wall of the material channel 1 adjacent to the working unit 2 via a mounting bracket. By placing the transformer on the outer wall of the material channel 1 adjacent to the working unit 2, the narrow space below the perforated plate 7 is avoided, ensuring that the perforated plate 7 and the transformer maintain an appropriate distance and do not interfere with each other. When replacing the perforated plate 7, there is no need to disassemble the transformer, thereby simplifying the operation, increasing the replacement speed of the perforated plate 7, ensuring the continuity of basalt continuous fiber production, and improving the furnace operating rate.

[0037] Optionally, the flow guiding device 3 includes a flow guiding channel, the material channel 1 has an inlet end and an outlet end, and the flow guiding channel is inclined downward from the outlet end of the material channel 1.

[0038] Furthermore, a support platform 10 is provided between the working unit 2 and the lifting mechanism 6. The working unit 2 is fixedly installed on the upper surface of the support platform 10, and the movable end of the lifting mechanism 6 is connected to the bottom of the support platform 10. The lifting mechanism 6 can drive the support platform 10 and the working unit 2 installed on the support platform 10 to perform vertical lifting and lowering movements. At the same time, the support platform 10 is movable, that is, the support platform 10 and the working unit 2 on its upper surface can move relative to the material channel 1. When it is necessary to replace the perforated plate 7 on the working unit 2, the support platform 10 can be moved away. During normal use, it can be moved to the initial designated position.

[0039] In one embodiment, a mounting groove 41 is formed on the upper surface of the sidewall 4, and a high-temperature seal 5 is disposed within the mounting groove 41. The high-temperature seal 5 includes a high-temperature pad 51, which is retractably disposed within the mounting groove 41. As one embodiment, referring to Figures 2 and 3, the mounting groove 41 is formed on one side of the sidewall 4, that is, the mounting groove 41 forms a mounting step on one side of the sidewall 4, and the high-temperature pad 51 is disposed on this mounting step. As another embodiment, the mounting groove 41 may also be a recessed structure formed on the sidewall 4 (a recess with only the top open).

[0040] Optionally, the high-temperature seal 5 also includes an elastic element 52, through which the high-temperature gasket 51 is connected to the mounting groove 41. The high-temperature gasket 51 can better seal and fit with the flow guiding device 3 through the elastic element 52.

[0041] Optionally, the high-temperature seal 5 also includes a connecting plate 53, a high-temperature pad 51 fixed to the upper surface of the connecting plate 53, and the lower surface of the connecting plate 53 connected to the mounting groove 41 by an elastic element 52.

[0042] Optionally, the elastic element 52 can be detachably connected to the mounting groove 41 via the mounting plate, so that the high-temperature seal 5 can be easily removed and replaced after long-term use.

[0043] Optionally, the high-temperature pad 51 may employ a multi-layered composite structure. For example, the high-temperature pad 51 may include a metal skeleton layer, a graphite sealing layer, and an anti-oxidation coating.

[0044] Optionally, the elastic element 52 can be a telescopic spring.

[0045] In one embodiment, a positioning block 11 is provided at the bottom of the flow guiding device 3, and an installation groove 41 is opened on one side of the side wall 4, so that the upper end of the side wall 4 on one side of the installation groove 41 forms a guide part 42. When the lifting mechanism 6 is not activated, there is a gap between the upper end of the guide part 42 and the bottom of the flow guiding device 3. When assembling the work unit 2, firstly, the work unit 2 is moved horizontally until one side of the guide part 42 (the left side wall of the installation groove 41) contacts the positioning block 11. At this time, the high-temperature sealing element 5 is just below the positioning block 11 (the elastic element 52 is not compressed, and a step is formed between the upper surface of the high-temperature pad 51 and the upper surface of the guide part 42). Then, the lifting mechanism 6 is activated, and the lifting mechanism 6 drives the work unit 2 and the side wall 4 to move upward, so that the guide part 42 seals against the bottom of the flow guiding device, and the high-temperature sealing element 5 seals against the bottom of the positioning block 11. The cooperation between the guide part 42 and the positioning block 11 not only facilitates centering and positioning, but also allows the upper end of the guide part 42 and the high temperature pad 51 to abut against the bottom of the flow guiding device 3 and the bottom of the positioning block 11 respectively to form a double seal.

[0046] In one embodiment, a flow-stopping device is provided in the material channel 1. The flow-stopping device can be set at the outlet of the material channel 1 to stop the flow of molten liquid, thereby facilitating the replacement of the work unit 2. That is, when the work unit 2 needs to be repaired (when the sprue is replaced), the flow-stopping device is first used to stop the material channel 1 from discharging molten liquid into the work unit 2. Then the work unit 2 to be repaired is moved away, and at the same time another normal work unit is moved in for use.

[0047] In one embodiment, a movable guide structure is also included, which includes a movable base 13 with rollers 12.

[0048] In one embodiment, the movable guide structure further includes a guide rail 14, which is mounted on the ground. The lifting mechanism 6 is mounted on the movable base 13, and the rollers 12 on the movable base 13 are slidably placed inside the guide rail 14. The sliding engagement between the rollers 12 and the guide rail 14 facilitates the movement of the support platform 10 and the working unit 2.

[0049] In one embodiment, a sealing block is provided at one end of the guide rail chute near the material channel 1. In use, when the roller 12 at the right end of the movable base 13 moves to the rightmost position of the guide rail and contacts the sealing block, the guide portion 42 of the side wall 4 also contacts the positioning stop 11.

[0050] In one embodiment, a limiting component is movably disposed on the guide rail 14 to restrict the movement of the roller 12. When the movable base 13 moves to a designated position, the limiting component can restrict the movement of the movable base 13 to ensure stability. For example, the limiting component includes: a limiting groove formed on the guide rail 14 and communicating with the guide rail slide groove; a limiting block is movably disposed in the limiting groove; a pushing member is connected to one side of the limiting block; in use, the pushing member can drive the limiting block to move along the limiting groove, thereby causing the limiting block to move closer to or further away from the roller, so as to limit and fix or release the roller.

[0051] The aforementioned flow-blocking device and limiting component are not shown in the diagram and are based on existing technology.

[0052] As a usage scenario: When the bottom sluice plate 7 of the working unit 2 is damaged and needs to be replaced, the basalt molten liquid is first intercepted outside the working unit 2 to be repaired by the interception device; then, the connection between the transformer, the conductive plate and the sluice plate 7 is disconnected, and the working unit 2 to be replaced with the sluice plate 7 is moved away. When moving away, the moving base 13 can be used to slide along the guide rail 14 to move it directly away; then another spare working unit with a working sluice plate 7 is used to continue production. When this working unit is moved into the assembly, the rollers 12 of the moving base 13 can be moved along the guide rail 14 towards the material channel 1. During the process, the side wall 4 will gradually move into the bottom of the guide device 3 until the guide part 42 on one side of the mounting groove 41 contacts the positioning block 11 and / or the rollers 12 contacts the sealing block. At this time, the working unit 2 has moved to the preset designated position. Then, the lifting mechanism 6 is started. The working unit moves down a certain distance under the drive of the lifting mechanism 6 until the upper end face of the guide part 42 and the high temperature pad 51 are respectively sealed and abutted against the bottom of the guide device 3 and the bottom of the positioning block 11. Finally, the basalt melt flows out from the holes in the sprue 7 and is drawn into basalt fibers by the drawing machine.

[0053] Any aspects not described in detail in this embodiment are techniques known in the art.

[0054] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
