Description

Technical Field

[0001] This utility model relates to the field of aluminum product processing technology, and in particular to a flow guiding mechanism for a soaking furnace. Background Technology

[0002] In the refined aluminum processing industry, ingot homogenization is an essential process. The purpose of homogenization is to eliminate internal stress through diffusion at high temperatures, reduce inhomogeneity and segregation within the ingot, and thus improve product performance. The homogenizing furnace used in the homogenization process is a key piece of equipment for improving ingot quality; its temperature uniformity directly affects product quality.

[0003] A search revealed a prior art disclosure of a homogenizing furnace flow guiding mechanism and homogenizing method (publication number: CN110157893A). The homogenizing furnace contains multiple layers of ingots, with air ducts for circulating air entering between adjacent layers of ingots. The flow guiding mechanism is located on both sides of the air ducts and installed on the furnace wall. The flow guiding mechanism includes a flow guiding plate that guides the airflow and an adjusting component for adjusting the distance between the flow guiding plate and the furnace wall. The adjusting component is connected between the flow guiding plate and the furnace wall.

[0004] In existing technologies, the airflow direction is mainly adjusted by adjusting the angle of the baffle plate. However, in actual production applications, relying on the baffle plate angle adjustment can easily result in an excessively large angle between the air and the aluminum material, causing too much air to impact the aluminum material and preventing it from entering the gaps between the aluminum material stacks. This affects airflow and consequently the uniformity of heating of the aluminum material. At the same time, the appearance, shape, and size differences of the aluminum material cannot be accommodated by adjusting the baffle plate angle to adapt to changes in product size, leaving room for optimization.

[0005] Therefore, we propose a flow guiding mechanism for a soaking furnace. Utility Model Content

[0006] The present invention mainly solves the technical problem of limited airflow range relying on the angle of the guide plate, and provides a guide mechanism for a soaking furnace.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a flow guiding mechanism for a soaking furnace, comprising:

[0008] The furnace body has an air inlet at the top and a guide assembly for guiding air inside. The guide assembly includes a guide plate and a connecting seat. The guide plate is rotatably connected to the connecting seat and forms a plate with a recessed top.

[0009] The first adjustment component is installed on the inner wall of the furnace body to adjust the installation height of the guide plate;

[0010] The second adjustment component is located on one side of the connector and is used to adjust the angle of the guide plate.

[0011] In a preferred embodiment of this utility model, the first adjusting component includes a guide rod, an adjusting screw, and a sliding seat. The guide rod and the adjusting screw are both fixedly installed to the furnace body, the sliding seat is slidably connected to the guide rod, the adjusting screw passes through the sliding seat, and fasteners are provided at the top and bottom of the sliding seat to limit its movement.

[0012] In a preferred embodiment of this utility model, the sliding seat is formed into a plate with a horizontal cross-section in the shape of a U, and the connecting seat is rotatably disposed in the groove of the sliding seat.

[0013] In a preferred embodiment of this utility model, the sliding seat has a sliding hole through which a guide rod is adapted, the guide rod is slidably disposed in the sliding hole, and the sliding seat also has a circular hole through which the adjusting screw extends to the bottom of the sliding seat.

[0014] In a preferred embodiment of this utility model, the fastener is a nut, both nuts are threadedly connected to the adjusting screw, and a spring washer is provided between the nut and the connecting seat.

[0015] In a preferred embodiment of this utility model, the guide plate includes a vertically extending straight plate and a curved extending arc plate, the arc plate and the straight plate being integrally formed, and the straight plate being locked and fixed to the connecting seat by bolts.

[0016] In a preferred embodiment of this utility model, the second adjusting component includes a thrust hole and a thrust bolt. A plurality of thrust holes are provided on one side of the connecting seat, and the thrust bolt is threadedly connected to the sliding seat.

[0017] As a preferred embodiment of the present invention, the side wall of the sliding seat is provided with an integrally formed ear plate, the ear plate has a threaded hole adapted to the thrust bolt, the thrust bolt is connected to the threaded hole, the thrust hole is a round hole, the thrust hole and the thrust bolt are clearance fit, and a plurality of thrust holes are distributed in a ring array on one side of the connecting seat.

[0018] This invention provides a flow guiding mechanism for a soaking furnace. It has the following beneficial effects:

[0019] 1. The flow guiding mechanism of this soaking furnace, by loosening the nuts above or below the sliding seat, pushes the sliding seat to move radially along the guide rod. When the guide plate reaches the designated position, the height of the connecting seat can be locked by tightening the two nuts and using the two nuts and spring washers to clamp the limiting connecting seat. Thus, the installation height of the connecting seat is locked and fixed, which is convenient to adjust according to the stacking of aluminum materials. This allows the guide plate to accurately guide air through the gaps between the aluminum materials. The adjustment method is simple and easy to operate, the overall structure is simplified, and the use and maintenance costs are low.

[0020] 2. The flow guiding mechanism of this soaking furnace, by loosening the thrust bolt, allows the end of the thrust bolt to exit from the thrust hole. At this time, the connecting seat can rotate freely around the rotating shaft and adjust the pitch angle of the guide plate. When the guide plate reaches the appropriate position, by tightening the thrust bolt, the end of the thrust bolt is inserted into another corresponding thrust hole to achieve thrust limit on the connecting seat. Thus, the air guiding angle of the guide plate can be adjusted and locked, further improving the accuracy of air guiding the aluminum material and ensuring the uniformity of heating of the aluminum material.

[0021] 3. The flow guiding mechanism of this homogenizing furnace allows for adjustment of the guide plate height by sliding the connecting seat radially along the guide rod. The angle of the guide plate is adjusted by rotating the connecting seat around the sliding seat, resulting in a flexible and adaptable position and angle for the guide plate. This provides good adaptability and flexibility for heating and homogenizing different aluminum materials, simplifies the adjustment of the guide plate position, and facilitates maintenance and replacement after deformation or damage. It has positive practical application effects.

[0022] 4. The flow guiding mechanism of this soaking furnace is equipped with a detachable guide plate. When the guide plate is deformed after use and needs to be reset, it can be removed, calibrated, reset, or replaced, which facilitates later maintenance. On the other hand, by setting several guiding components, the gaps between stacked aluminum materials can be evenly supplied with air to ensure uniform heating. A set of guiding components can be set at the gap between two adjacent layers of aluminum materials to achieve precise air guiding. Attached Figure Description

[0030] A flow guiding mechanism for a soaking furnace, such as Figure 1 , Figure 2 and Figure 3 as well as Figure 4 As shown, it includes:

[0031] The furnace body 10 has an air inlet at the top and a guide assembly for guiding air inside. The guide assembly includes a guide plate 20 and a connecting seat 21. The guide plate 20 is rotatably connected to the connecting seat 21. The guide plate 20 forms a plate with a recessed top. The guide plate 20 includes a vertically extending straight plate and a curved extending arc plate. The arc plate and the straight plate are integrally formed. The straight plate is locked and fixed to the connecting seat 21 by bolts.

[0032] By setting a detachable guide plate 20, when the guide plate 20 is deformed after use and needs to be reset, it can be removed, calibrated, reset, or replaced, which facilitates later maintenance. On the other hand, by setting several guiding components, the gaps between stacked aluminum materials can be evenly supplied with air to ensure uniform heating. A set of guiding components can be set at the gap between two adjacent layers of aluminum materials to achieve precise air guidance.

[0033] like Figure 3 and Figure 4 As shown, the first adjustment component is installed on the inner wall of the furnace body 10 to adjust the installation height of the guide plate 20;

[0034] The first adjustment assembly includes a guide rod 22, an adjustment screw 23, and a sliding seat 24. The guide rod 22 and the adjustment screw 23 are both fixedly installed on the furnace body 10. The sliding seat 24 is slidably connected to the guide rod 22. The adjustment screw 23 passes through the sliding seat 24. Fasteners are provided at the top and bottom of the sliding seat 24 to limit the sliding seat 24. The sliding seat 24 forms a plate with a horizontal cross section in the shape of a U. The connecting seat 21 is rotatably set in the groove of the sliding seat 24. The sliding seat 24 has a sliding hole adapted to the guide rod 22. The guide rod 22 is slidably set in the sliding hole. The sliding seat 24 also has a round hole. The adjustment screw 23 passes through the round hole and extends to the bottom of the sliding seat 24. The fastener is a nut 25. Both nuts 25 are threadedly connected to the adjustment screw 23. A spring washer is provided between the nut 25 and the connecting seat 21. Specifically, the connecting seat 21 is rotatably connected to the sliding seat 24 through a rotating shaft. The rotating shaft is limited by a retaining spring to prevent it from falling off.

[0035] In this solution, to adjust the installation height of the guide plate 20, the nut 25 above or below the sliding seat 24 is loosened, pushing the sliding seat 24 to move radially along the guide rod 22. When the guide plate 20 reaches the designated position, the two nuts 25 are tightened, and the two nuts 25 and the spring washer are used to clamp the limiting connecting seat 21, thereby locking the height of the connecting seat 21. The installation height of the connecting seat 21 is locked and fixed, which is convenient for adjustment according to the stacking of aluminum materials. This allows the guide plate 20 to accurately guide air through the gaps between aluminum materials. The adjustment method is simple and easy to operate, the overall structure is simplified, and the use and maintenance costs are low.

[0036] like Figure 5 and Figure 6 As shown, the second adjustment component is located on one side of the connecting seat 21 and is used to adjust the angle of the guide plate 20;

[0037] The second adjustment component includes a thrust hole 30 and a thrust bolt 31. Several thrust holes 30 are opened on one side of the connecting seat 21. The thrust bolt 31 is threadedly connected to the sliding seat 24. The side wall of the sliding seat 24 is provided with an integrally formed ear plate. The ear plate is provided with a threaded hole adapted to the thrust bolt 31. The thrust bolt 31 is connected to the threaded hole. The thrust hole 30 is a round hole. The thrust hole 30 and the thrust bolt 31 are clearance-fitted. Several thrust holes 30 are distributed in a circular array on one side of the connecting seat 21.

[0038] To adjust the air guide angle of the guide plate 20, the thrust bolt 31 is loosened, and the end of the thrust bolt 31 is removed from the thrust hole 30. At this time, the connecting seat 21 can rotate freely around the pivot and adjust the pitch angle of the guide plate 20. When the guide plate 20 reaches the appropriate position, the thrust bolt 31 is tightened, and the end of the thrust bolt 31 is inserted into another corresponding thrust hole 30 to achieve the thrust limit of the connecting seat 21. Thus, the air guide angle of the guide plate 20 can be adjusted and locked, further improving the accuracy of air guide for the aluminum material and ensuring the uniformity of heating of the aluminum material.

[0039] The height of the guide plate 20 can be adjusted by sliding the connecting seat 21 radially along the guide rod 22. The angle of the guide plate 20 can also be adjusted by rotating the connecting seat 21 around the sliding seat 24. This allows the position and angle of the guide plate 20 to be flexible and adaptable, demonstrating good adaptability and flexibility in heating and homogenizing different aluminum materials. It simplifies the adjustment of the position of the guide plate 20 and facilitates maintenance and replacement after the guide plate 20 is deformed or damaged, thus having a positive practical application effect.

[0040] The working principle of this utility model is as follows: Loosen the thrust bolt 31, and the end of the thrust bolt 31 exits from the thrust hole 30. At this time, the connecting seat 21 can rotate freely around the rotating shaft and adjust the pitch angle of the guide plate 20. When the guide plate 20 reaches the appropriate position, tighten the thrust bolt 31. The end of the thrust bolt 31 is inserted into another corresponding thrust hole 30 to realize the thrust limit of the connecting seat 21. Then the air guiding angle of the guide plate 20 can be adjusted and locked. Loosen the nuts 25 above or below the sliding seat 24 and push the sliding seat 24 to move radially along the guide rod 22. When the guide plate 20 reaches the designated position, tighten the two nuts 25. Use the two nuts 25 and the spring washer to clamp and limit the connecting seat 21 to lock the height of the connecting seat 21. Then the height of the connecting seat 21 is locked and fixed. Adjust the height and angle of the guide plate 20 to optimize the air guidance and ensure uniform heating of the aluminum material.

[0041] The guide rod 22 is made of high-temperature alloy and coated with an alumina ceramic layer. The sliding hole is embedded with a graphite copper alloy bushing (working temperature limit 800℃). The single-sided gap is designed to be 0.3-0.5mm (at room temperature) to reserve space for thermal expansion. The fastening nut 25 is made of disc spring washer set.

[0042] The thrust holes 30 are distributed in a ring at 5° intervals, corresponding to a pitch angle adjustment range of ±30° for the guide plate 20. The end of the thrust bolt 31 is machined with a 60° tapered head to form a line contact and lock with the thrust hole 30;

[0043] The surface of the guide plate 20 is polished and coated with a high-temperature anti-stick coating (such as WS2-based solid lubricant) to reduce flow field distortion caused by dust accumulation;

[0044] The furnace body 10 includes a shell and an inner lining: the outer shell is a steel structure, the inner lining is made of all-alumina silicate refractory fiber, and stainless steel resistance heating tubes are installed on the inner wall of the inner lining. An axial flow reversible fan is provided on the top of the furnace body 10 to supply air to the air inlet. An air guide pipe is installed at the air inlet to guide air to each guide plate 20, which will not be described in detail here.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
