Description

Technical Field

[0001] This utility model belongs to the field of aluminum alloy profile cooling technology, and in particular relates to a cooling device for aluminum alloy profile processing. Background Technology

[0002] Aluminum alloy profiles are one of the most widely used non-ferrous metal structural materials in industry. They are aluminum-based alloys with added elements, manufactured through processing and extrusion. During the processing of aluminum alloy profiles, such as after hot extrusion, welding, or machining, they often require air or water cooling to quickly remove heat from the high-temperature profiles and lower their temperature to a predetermined range for subsequent processing.

[0003] For example, a cooling device for aluminum alloy profile processing proposed in announcement number CN221549366U includes a housing. A filter screen is provided in the lower part of the inner cavity of the housing. The filter screen divides the housing into an upper cooling chamber and a lower liquid guiding chamber. A cooling component is provided on the upper part of the housing.

[0004] The above-mentioned patent has the following defects in use:

[0005] The cooling assembly mainly sprays water downwards from the cooling nozzles above to cool the aluminum alloy profiles in the placement frame. However, it only sprays water from above, mainly affecting the top of the aluminum alloy profiles. If a batch of aluminum alloy profiles are placed in the placement frame, only the top aluminum alloy profiles can receive effective spray cooling, while the bottom aluminum alloy profiles are difficult to receive effective spray cooling. At the same time, other directions such as front, back, left, and right are also difficult to effectively spray cool, resulting in insufficient spray cooling. Therefore, this utility model proposes a cooling device for aluminum alloy profile processing. Utility Model Content

[0006] This utility model provides a cooling device for aluminum alloy profile processing. A layered placement mechanism allows batches of aluminum alloy profiles to be independently placed on multiple U-shaped filter screens. Combined with elastic straps, hooks, and I-shaped rods, the aluminum alloy profiles are secured within the U-shaped filter screens, preventing them from falling off during subsequent rotation. The independent layering of the aluminum alloy profiles within the placement frame eliminates stacking and obstruction, facilitating subsequent spray cooling. A multi-directional spray mechanism drives a pair of water pumps, which in turn drive water from a transparent water tank through a top spray pipe and a pair of side spray pipes, spraying it onto the aluminum alloy profiles from the top and sides. A drive motor, via a rotating shaft, slowly rotates the placement frame, adjusting the side spray direction (e.g., the front and rear sides of the aluminum alloy profile will be rotated to the left and right spray coverage areas). This achieves spray cooling of the aluminum alloy profiles from the top, front, back, left, and right sides, reducing blind spots caused by single-direction spraying and making spray cooling more thorough and comprehensive. In summary, this solves the problems in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model discloses a cooling device for processing aluminum alloy profiles, comprising:

[0009] A cooling box, wherein a sealed door is hinged to the outer wall of the cooling box, a filter screen is fixedly connected to the inner wall of the cooling box, and a mesh frame is provided on the top of the filter screen; and a transparent water tank is fixedly connected to the top of the cooling box.

[0010] A layered placement mechanism is provided within a placement frame and is used to place batches of aluminum alloy profiles into the placement frame in layers.

[0011] A multi-directional spraying mechanism is installed on the cooling box and is used to spray aluminum alloy profiles in multiple directions.

[0012] The multi-directional spray mechanism includes a pair of water pumps fixedly connected to the top of the cooling box. The cooling box has a pair of water suction pipes inside, and the ends of the two water suction pipes that are far apart penetrate the side wall of the cooling box and are fixedly connected to the water suction ends of the pair of water pumps. The drain ends of the pair of water pumps are fixedly connected to water guide pipes. The cooling box has a top spray pipe and a pair of side spray pipes inside, and the two ends of the top spray pipe and the ends of the two side spray pipes that are far apart penetrate the side wall of the cooling box and are fixedly connected to the outer wall of the pair of water guide pipes. The top spray pipe and the pair of side spray pipes are located at the top and the two sides of the mesh frame, respectively, and multiple cooling nozzle bodies are fixedly connected to the bottom end of the top spray pipe and the opposite side of the pair of side spray pipes.

[0013] Furthermore, the layered placement mechanism includes multiple movable filter plates, both sides of which are slidably connected to the inner wall of the placement frame. Multiple connecting vertical blocks are fixedly connected to the top of each movable filter plate, and a U-shaped filter screen is fixedly connected to the top of each connecting vertical block. An elastic strap is fixedly connected to the side of the connecting vertical block away from the sealing door, and a hook is fixedly connected to one end of the elastic strap. An I-shaped rod is fixedly connected to the side of the connecting vertical block near the sealing door, and the hook is engaged with the outer wall of the I-shaped rod.

[0014] Furthermore, connecting plates are fixedly connected to both sides of the multiple movable filter plates, and multiple pairs of connecting plates are connected to the side where the mesh frame is placed by cross screws.

[0015] Furthermore, sliding blocks are fixedly connected to both sides of the multiple movable filter plates, and multiple grooves are carved into the inner walls of both sides of the mesh frame, with the sliding blocks located in the grooves and slidably connected to them.

[0016] Furthermore, a sealing plug is fitted on the top of the transparent water tank, and the outer wall of the sealing plug is in close contact with the inner wall of the transparent water tank.

[0017] Furthermore, a geared motor and a waterproof and breathable cover are fixedly connected to the inner bottom of the cooling box, and the geared motor is located inside the waterproof and breathable cover. A rotating shaft is rotatably connected between the waterproof and breathable cover and the filter screen through a bearing. The top end of the rotating shaft is fixedly connected to the bottom end of the screen frame, and the bottom end of the rotating shaft is fixedly connected to the output end of the geared motor.

[0018] Furthermore, a pair of drain outlets are cut into the inner bottom of the cooling box.

[0019] The present invention has the following advantages over the prior art:

[0020] 1. Layered independent placement: This technical solution uses a layered placement mechanism to place batches of aluminum alloy profiles independently on multiple U-shaped filter screens. With the help of elastic straps, hooks, and I-shaped rods, the aluminum alloy profiles are bound within the U-shaped filter screens, making them less likely to fall off during subsequent rotation. Furthermore, the independent placement of batches of aluminum alloy profiles within the placement frame, without stacking or obstruction, is beneficial for subsequent spray cooling.

[0021] 2. Multi-directional spray cooling: This technical solution uses a multi-directional spray mechanism to drive a pair of water pumps, which in turn drive water from the inside of the transparent water tank through the top spray pipe and a pair of side spray pipes to spray onto the aluminum alloy profile from the top and sides. The drive reduction motor drives the placement mesh frame to rotate slowly through the rotating shaft, adjusting the side spray direction (e.g., the front and back sides of the aluminum alloy profile will turn to the left and right side spray coverage area), thereby achieving spray cooling treatment of the aluminum alloy profile from the top and the front, back, left and right sides, reducing the blind spot problem of single-direction spraying, and making the spray cooling more thorough and comprehensive.

[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0035] Please see Figures 1-6 As shown, a cooling device for processing aluminum alloy profiles according to this utility model includes:

[0036] Cooling box 1, with a sealing door 2 hinged to the outer wall of cooling box 1, a filter screen plate 4 fixedly connected to the inner wall of cooling box 1, and a mesh frame 3 placed on the top of filter screen plate 4, and a transparent water tank 6 fixedly connected to the top of cooling box 1.

[0037] Layered placement mechanism 5 is set inside the placement frame 3 and is used to place batch aluminum alloy profiles in layers inside the placement frame 3.

[0038] A multi-directional spraying mechanism 8 is installed on the cooling box 1 and is used to spray aluminum alloy profiles in multiple directions.

[0039] The multi-directional spray mechanism 8 includes a pair of water pumps 801 fixedly connected to the top of the cooling box 1. The cooling box 1 is equipped with a pair of water suction pipes 802, and the ends of the two water suction pipes 802 that are far apart pass through the side wall of the cooling box 1 and are fixedly connected to the water suction end of the pair of water pumps 801 respectively. The drain ends of the pair of water pumps 801 are fixedly connected to water guide pipes 803. The cooling box 1 is equipped with a top spray pipe 804 and a pair of side spray pipes 805, and the two ends of the top spray pipe 804 and the ends of the two side spray pipes 805 that are far apart pass through the side wall of the cooling box 1 and are fixedly connected to the outer wall of the pair of water guide pipes 803 respectively. The top spray pipe 804 and the pair of side spray pipes 805 are located at the top and the two sides of the mesh frame 3 respectively, and multiple cooling nozzle bodies 806 are fixedly connected to the bottom end of the top spray pipe 804 and the opposite side of the pair of side spray pipes 805 respectively.

[0040] In the specific implementation process, after the batch of aluminum alloy profiles are placed independently in layers inside the placement frame 3, a pair of water pumps 801 are driven to draw cooling water from the transparent water tank 6 through the water pumping pipe 802. The water is then diverted through the water guide pipe 803 to the top spray pipe 804 and a pair of side spray pipes 805. Multiple cooling nozzles 806 at the bottom of the top spray pipe 804 spray vertically downwards. At the same time, a pair of side spray pipes 805 on the left and right sides drive multiple cooling nozzles 806 on their opposite sides (the specific spraying angle of the cooling nozzles 806 is determined according to the actual use. For example, in this embodiment, the top cooling nozzles 806 spray vertically downwards, and the side cooling nozzles 806 spray at a 45° angle towards the central axis of the placement frame 3) to spray the sides of the aluminum alloy profiles. This is more thorough and comprehensive than spraying in a single direction.

[0041] The transparent water tank 6 is fitted with a sealing plug 7 on its top, and the outer wall of the sealing plug 7 is in close contact with the inner wall of the transparent water tank 6.

[0042] Open the sealing plug 7 on the top of the transparent water tank 6 and fill it with cooling water (the transparent water tank 6 is made of polycarbonate material with a temperature resistance of ≥80℃ and an impact strength of ≥20kJ / m², ensuring high temperature resistance and not easily damaged. The water level can be observed in real time through the transparent setting of the transparent water tank 6 to avoid water shortage). After adding water, cover the sealing plug 7 to prevent impurities from falling in.

[0043] The cooling box 1 is fixedly connected to a geared motor 807 and a waterproof and breathable cover 9 at its inner bottom. The geared motor 807 is located inside the waterproof and breathable cover 9. The waterproof and breathable cover 9 and the filter screen 4 are rotatably connected by a rotating shaft 808 through a bearing. The top end of the rotating shaft 808 is fixedly connected to the bottom end of the mesh frame 3, and the bottom end of the rotating shaft 808 is fixedly connected to the output end of the geared motor 807.

[0044] During the lateral spraying process, after the left and right sides of the aluminum alloy profile are sprayed for a period of time, the drive reduction motor 807 slowly rotates (in this embodiment, the specific turning cycle is determined according to the maximum side length of the aluminum alloy profile cross-section: when the maximum side length of the cross-section is ≤100mm, the drive reduction motor (807) rotates 90° clockwise every 30 seconds; when the maximum side length of the cross-section is >100mm, the drive reduction motor (807) rotates 90° clockwise every 60 seconds, with a rotational angular velocity of 5° / s), and drives the placement frame 3 to rotate through the rotating shaft 808, so that the front and rear sides of the aluminum alloy profile will turn to the left and right side spraying coverage area, so as to receive multiple cooling nozzles on a pair of side spray pipes 805. After the front and rear sides of the aluminum alloy profile are sprayed and cooled for a period of time, the reduction motor 807 is driven again to adjust the spray direction of the aluminum alloy profile and perform periodic turning. This is to achieve spray cooling treatment of the aluminum alloy profile from the top and the front, rear, left and right sides, reduce the blind spot problem of spraying in one direction, and make the spray cooling more thorough and comprehensive. In this embodiment, the waterproof and breathable cover 9 is made of 304 stainless steel. Its side wall is evenly chiseled with vent holes with a diameter of 2-3mm (hole spacing 10mm), and the inside of the vent holes is pasted with a PTFE waterproof and breathable membrane (thickness 0.1mm), which not only prevents cooling water from entering, but also ensures heat dissipation and ventilation of the reduction motor 807.

[0045] The cooling box 1 has a pair of drain outlets 10 cut into its inner bottom.

[0046] The wastewater after spraying carries impurities such as oxide scale and debris from the surface of the aluminum alloy profile. It first falls through the mesh of the mesh frame 3 and the movable filter plate 501 to the filter screen plate 4. The filter screen plate 4 intercepts the impurities, and the filtered wastewater is collected at the bottom of the cooling tank 1 and finally discharged through a pair of drain outlets 10. (In this embodiment, it is possible to select an external pipeline to guide it to the wastewater treatment system, or to return it to the transparent water tank 6 after purification to achieve circulation. The specific choice depends on the actual use.) Specific Implementation Example 2:

[0048] Please see Figure 2 and Figures 4-6 As shown, in a preferred embodiment, the layered placement mechanism 5 includes multiple movable filter plates 501. Both sides of the multiple movable filter plates 501 are slidably connected to the inner wall of the placement frame 3. Multiple connecting vertical blocks 505 are fixedly connected to the top of the movable filter plates 501. U-shaped filter screens 506 are fixedly connected to the top of each of the multiple connecting vertical blocks 505. An elastic strap 507 is fixedly connected to the side of the connecting vertical block 505 away from the sealing door 2. A hook 508 is fixedly connected to one end of the elastic strap 507. An I-shaped rod 509 is fixedly connected to the side of the connecting vertical block 505 near the sealing door 2. The hook 508 is engaged with the outer wall of the I-shaped rod 509.

[0049] In the specific implementation process, the batch of aluminum alloy profiles are first placed in layers on multiple U-shaped filters 506 (the side wall height of the U-shaped filter 506 is 1 / 3-1 / 2 of the cross-sectional height of the aluminum alloy profile (and the maximum height does not exceed 50mm). The U-shaped filter 506 uses stainless steel woven mesh with a mesh size of 5-8mm (wire diameter 1mm), which ensures support stability, avoids obstructing lateral spraying, and does not hinder cooling water penetration). Then, the elastic strap 507 is pulled to bind along the top of the aluminum alloy profile, so that the hook 508 on the elastic strap 507 is engaged with the I-shaped rod 509, binding the aluminum alloy profile in the U-shaped filter 506, making it less likely to fall off during subsequent rotation. Then, multiple movable filter plates 501 are slid into the placement frame 3, causing the batch of aluminum alloy profiles to be placed in layers on the placement frame 3 without stacking or obstruction, which is beneficial for subsequent spray cooling.

[0050] Among them, multiple movable filter plates 501 are fixedly connected to both sides of the connecting plate 502, and multiple pairs of connecting plates 502 are connected to one side of the mesh frame 3 by cross screws.

[0051] After the movable filter plate 501 slides into the placement frame 3, the cross screw is turned to lock the connecting plate 502 to the side wall of the placement frame 3, preventing the movable filter plate 501 from shifting due to the rotation of the placement frame 3 during the cooling process.

[0052] Among them, sliding blocks 503 are fixedly connected to both sides of multiple movable filter plates 501, and multiple grooves 504 are carved on both sides of the inner wall of the mesh frame 3, and the sliding blocks 503 are located in the grooves 504 and are slidably connected to them.

[0053] The movable filter plate 501 can be extended into the placement frame 3 for placement by sliding along the slide groove 504 via the sliding block 503.

[0054] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0055] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0056] The working principle of this utility model is as follows:

[0057] In use, this invention first places batches of aluminum alloy profiles in layers on multiple U-shaped filter screens 506. Then, the elastic straps 507 are pulled to bind the aluminum alloy profiles along the top, so that the hooks 508 on the elastic straps 507 are engaged with the I-shaped rods 509, binding the aluminum alloy profiles within the U-shaped filter screens 506. Next, multiple movable filter plates 501 are slid into the placement frame 3 via sliding blocks 503 along the slide grooves 504. Then, the cross screws are tightened to lock the connecting plate 502 to the side wall of the placement frame 3. Next, during spray cooling, a pair of water pumps 801 are driven to draw cooling water from the transparent water tank 6 through the water pipes 802, which is then diverted through the water guide pipes 803 to the top spray pipe 804 and a pair of side spray pipes 805. Multiple cooling nozzles 806 at the bottom of the top spray pipe 804 spray vertically downwards, while the pair of side spray pipes 805 on the left and right sides spray downwards. Multiple cooling nozzles 806 on the side spray water onto the left and right sides of the aluminum alloy profile. After the left and right sides of the aluminum alloy profile have been sprayed for a period of time, the drive reduction motor 807 slowly rotates and drives the placement mesh frame 3 to rotate through the rotating shaft 808. This causes the front and rear sides of the aluminum alloy profile to turn towards the left and right side spray coverage area so that they can receive the spray from the multiple cooling nozzles 806 on the pair of side spray pipes 805. After the front and rear sides of the aluminum alloy profile have been sprayed and cooled for a period of time, the drive reduction motor 807 is driven again to adjust the side spray direction of the aluminum alloy profile, performing periodic turning and spray cooling. The wastewater after spraying carries impurities such as oxide scale and debris on the surface of the aluminum alloy profile. It first falls through the mesh of the placement mesh frame 3 and the movable filter plate 501 to the filter screen plate 4. The filter screen plate 4 intercepts the impurities. The filtered wastewater collects at the bottom of the cooling box 1 and is finally discharged through a pair of drain outlets 10.
