Description

Technical Field

[0001] This utility model belongs to the technical field of tilting furnace accessories, and in particular relates to a prefabricated structure for the aluminum outlet of a tilting furnace. Background Technology

[0002] Tilting furnaces are important equipment in the metallurgical industry for smelting and pouring molten aluminum. Their main feature is that the furnace body can be tilted, which facilitates the pouring and unloading of molten aluminum. The performance of the aluminum outlet structure directly affects production efficiency and equipment lifespan.

[0003] Existing tilting furnaces mostly use rotary joint devices for their aluminum outlets, with a small, circular inner hole. This structure has significant drawbacks in large-capacity tilting furnaces: First, the limited throughput of the circular hole makes it difficult to meet the aluminum discharge requirements of large-capacity furnaces, resulting in low production efficiency. Second, the rotary joint typically uses two 90-degree rotating components for connection, which easily creates turbulence in the molten aluminum flow. This not only increases the scouring force on the refractory material, reducing its service life, but also easily causes poor aluminum flow, further affecting production efficiency. Furthermore, this structure is cumbersome to install, requiring precise alignment of the two rotating components, increasing installation difficulty and maintenance costs.

[0004] To address these issues, we provide a prefabricated structure for the aluminum outlet of a tilting furnace. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated structure for the aluminum outlet of a tilting furnace. Through the cooperation of the flow guiding mechanism and the installation mechanism, the problems of small aluminum discharge and inconvenient installation in the existing tilting furnace aluminum outlet structure are solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a prefabricated structure for an aluminum outlet of a tilting furnace, comprising an installation plate, a joint flow port fixedly connected to one side of the installation plate, and a furnace-turning flow channel provided on the surface of one side of the joint flow port; a flow guiding mechanism is provided on one side of the installation plate, the flow guiding mechanism including a first square channel opened on one side of the joint flow port and a second square channel opened on one side of the furnace-turning flow channel; an installation mechanism is provided on one side of the furnace-turning flow channel, the installation mechanism including a sealing plate disposed on the top of the furnace-turning flow channel, a retaining plate fixedly connected to the bottom of the sealing plate, and an arc-shaped retaining groove opened on the top of the joint flow port.

[0008] The present invention is further configured such that the installation mechanism includes a bracket fixedly connected to the top of the inverted flow channel, a threaded rod rotatably connected to the bottom of the bracket, a threaded sleeve threadedly connected to the surface of the threaded rod, a connecting bracket fixedly connected to one side of the threaded sleeve, and a handwheel fixedly connected to the top of the threaded rod.

[0009] The present invention is further configured such that the installation mechanism includes an arc-shaped positioning block fixedly connected to the bottom of the joint outlet, and an arc-shaped positioning groove opened in the bottom of the inverted furnace channel.

[0010] The present invention is further configured such that the bottom of the card plate contacts the arc-shaped card slot, and the first square channel and the second square channel are connected.

[0011] The present invention is further configured such that a mounting hole is provided on one side of the mounting plate, and the joint outlet is in close contact with the furnace invert.

[0012] The present invention is further configured such that a slider is fixedly connected to one side of the threaded sleeve, and the slider is slidably connected to one side of the bracket.

[0013] The present invention is further configured such that the widths of the second square channel, the joint flow port, and the card plate are all the same, and the sealing plate is in contact with the reverse flow.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model, by adopting a square channel with a straight design, significantly increases the throughput of molten aluminum compared to the traditional circular rotary joint, meeting the needs of large-capacity tilting furnaces and improving production efficiency. The straight flow channel design reduces the formation of turbulence during the flow of molten aluminum, reduces the scouring force on the joint outlet and the tilting flow channel, thereby reducing the wear of refractory materials and extending the service life of the equipment. Through the cooperation of the clamping plate, arc-shaped groove, arc-shaped positioning block and positioning baffle, the quick positioning and installation of the tilting flow channel is realized, simplifying the installation process and improving the ease of operation. The design of the threaded rod and handwheel makes the disassembly process easier, reducing maintenance costs and time, and facilitating daily maintenance and component replacement of the equipment.

[0016] 2. This utility model ensures the sealing of the connection between the joint outlet and the inverted flow channel through the contact between the sealing plate and the inverted flow channel, as well as the cooperation between the clamping plate and the arc-shaped clamping groove, preventing aluminum leakage and improving safety. The joint outlet can be rotated to an inclined state as needed, while the first square channel and the second square channel remain in a straight line connection, ensuring smooth aluminum discharge. It is suitable for different working conditions. The design of the arc-shaped positioning block and the arc-shaped positioning groove enhances the connection stability between the joint outlet and the inverted flow channel, making the rotation process smoother and reducing the risk of vibration and loosening during equipment operation.

[0025] The technical solutions of the present invention will be described below with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only some embodiments of the present invention, and not all embodiments. Example

[0026] Please see Figures 1-5This utility model relates to a prefabricated structure for an aluminum outlet of a tilting furnace, comprising a mounting plate 1 connected to the tilting furnace. The mounting plate 1 is hollow to ensure normal aluminum discharge. A joint outlet 2 is fixedly connected to one side of the mounting plate 1, and a furnace-turning flow channel 3 is provided on the surface of one side of the joint outlet 2. A flow guiding mechanism is provided on one side of the mounting plate 1, comprising a first square channel 4 on one side of the joint outlet 2 and a second square channel 5 on one side of the furnace-turning flow channel 3. The joint outlet 2 and the furnace-turning flow channel 3 are horizontally designed and remain horizontal after installation and fixing, so that the first square channel 4 and the second square channel 5 are connected to form a straight line, which facilitates aluminum discharge and reduces the damage caused by aluminum impact to the joint outlet 2 and the furnace-turning flow channel 3. At the same time, the first square channel 4 and the second square channel 5 are connected to form a straight line, which facilitates aluminum discharge and reduces the damage caused by aluminum impact to the joint outlet 2 and the furnace-turning flow channel 3. Compared to the round hole design, the aluminum discharge hole 5 has a larger flow rate, improving production efficiency. If the joint outlet 2 is rotated to an inclined state as needed during the aluminum discharge process, the aluminum discharge between the first square channel 4 and the second square channel 5 is still a straight line. An installation mechanism is provided on one side of the inverted flow channel 3. The installation mechanism includes a sealing plate 6 set on the top of the inverted flow channel 3, a clamping plate 7 fixedly connected to the bottom of the sealing plate 6, and an arc-shaped clamping groove 8 opened on the top of the joint outlet 2. The bottom of the clamping plate 7 penetrates into the inner cavity of the inverted flow channel 3 and is clamped into the arc-shaped clamping groove 8. The top of the inverted flow channel 3 has a movable groove that matches the clamping plate 7. The clamping plate 7 can rotate along the arc-shaped clamping groove 8. The clamping plate 7 clamps and limits the inverted flow channel 3 and ensures that it can rotate normally to the inclined state. At the same time, it can seal the space between the inverted flow channel 3 and the joint outlet 2. Example

[0027] Please see Figures 1-5Based on Embodiment 1, the installation mechanism further includes a bracket 9 fixedly connected to the top of the inverted flow channel 3, a threaded rod 10 rotatably connected to the bottom of the bracket 9, the top of the threaded rod 10 extending to the top of the bracket 9 and connected to a handwheel 13, the threaded rod 10 and the bracket 9 being rotatably connected via bearings, the bottom of the threaded rod 10 also being rotatably connected to the inverted flow channel 3 via bearings, a threaded sleeve 11 threadedly connected to the surface of the threaded rod 10, a connecting frame 12 fixedly connected to one side of the threaded sleeve 11, the bottom of the connecting frame 12 being fixedly connected to the sealing plate 6, and a handwheel 13 fixedly connected to the top of the threaded rod 10. The installation mechanism also includes an arc-shaped positioning block 14 fixedly connected to the bottom of the joint flow port 2, and an arc-shaped positioning groove 15 formed in the bottom of the inverted flow channel 3. The size is adapted to the arc-shaped positioning block 14. During installation, the arc-shaped positioning block 14 is completely inserted into the arc-shaped positioning groove 15. When the joint flow port 2 rotates, it rotates around the arc-shaped positioning block 14 as the center. The bottom of the clamping plate 7 is in contact with the arc-shaped clamping groove 8. The first square channel 4 and the second square channel 5 are connected. An installation hole 16 is opened on one side of the mounting plate 1. The joint flow port 2 is in close contact with the furnace flow channel 3. The front and rear sides and the bottom of the joint flow port 2 are in close contact with the inner wall of the furnace flow channel 3. A slider is fixedly connected to one side of the threaded sleeve 11. The slider is slidably connected to one side of the bracket 9. A groove adapted to the slider is opened on one side of the bracket 9. The widths of the second square channel 5, the joint flow port 2 and the clamping plate 7 are the same. The sealing plate 6 is in contact with the furnace flow channel 3.

[0028] The working principle of this invention is as follows: After the molten aluminum flows out of the tilting furnace, it passes sequentially through the first square channel 4 of the joint outlet 2 and the second square channel 5 of the tilting furnace trough 3. Because the two are horizontally aligned and have a straight square design, the molten aluminum flows smoothly with a large flow rate and little turbulence, thus completing the discharge efficiently.

[0029] Align the arc-shaped positioning block 14 of the inverted flow channel 3 with the arc-shaped positioning groove 15 of the joint flow port 2. Rotate the handwheel 13 to rotate the threaded rod 10, causing the threaded sleeve 11 to move downwards, pushing the sealing plate 6 and connecting bracket 12 downwards, so that the clamping plate 7 is engaged in the arc-shaped clamping groove 8, completing the limiting and sealing. Rotate the handwheel 13 in the opposite direction, and the threaded sleeve 11 moves upwards, causing the sealing plate 6 and clamping plate 7 to disengage from the arc-shaped clamping groove 8. The joint flow port 2 can then be easily removed for maintenance or replacement. When it is necessary to tilt the furnace during use, the joint flow port 2 rotates around the arc-shaped positioning block 14 as the center. During the rotation, the arc-shaped positioning block 14 and clamping plate 7 make the rotation more stable and continuously seal the joint flow port 2 and the inverted flow channel 3. By optimizing the flow channel structure and installation method, the problems of small aluminum discharge and complicated installation of traditional tilting furnaces are solved. It has the characteristics of high efficiency, durability and easy maintenance, and is suitable for the needs of large-scale industrial production.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
