Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically to a rapid cooling device for aluminum profile production. Background Technology

[0002] Aluminum profiles are alloy materials with aluminum as the main component. Aluminum rods are melted and extruded to obtain aluminum materials with different cross-sectional shapes. However, the mechanical properties and application fields of the industrial aluminum profiles produced are different depending on the proportion of alloys added.

[0003] During the extrusion molding process, aluminum rods themselves have a high temperature, and the extrusion process generates a large amount of heat, resulting in a high temperature for the formed aluminum profile. Therefore, it is necessary to cool the aluminum profile. The conventional cooling method is spray cooling, such as the aluminum profile cooling device described in patent number 2022225908769, which describes a cooling device that can spray cooling on aluminum profiles during the transmission process. However, it was found in operation that although this method can effectively reduce the surface temperature of the aluminum profile, the side of the aluminum profile in contact with the conveyor belt cannot be sprayed with cooling water. Therefore, the temperature reduction rate is slowed down, resulting in a large temperature difference between different parts of the aluminum profile, which easily generates thermal stress and causes the aluminum profile to break.

[0004] A patent with publication number CN222535916U is disclosed in the prior art. The solution includes a workbench with a transmission trough and a transmission roller on the trough. A semi-circular cover is set on the workbench, and several spray heads are set in the middle of the top of the semi-circular cover. The spray heads are connected to a first water pipe, one end of which passes through the semi-circular cover. Several high-pressure spray heads are set at the bottom of the transmission trough, located below the transmission roller. The high-pressure spray heads are connected to a second water pipe, one end of which passes through the workbench and connects to the outside. By setting a semi-circular cover and setting spray heads inside the semi-circular cover, the aluminum profile passing through the semi-circular cover can be sprayed and cooled. The high-pressure spray heads at the bottom of the transmission trough on the workbench can spray and cool the aluminum profile above the transmission roller, preventing uneven cooling and excessively high local temperatures that could cause thermal stress and breakage of the aluminum profile.

[0005] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:

[0006] First, existing aluminum profiles have grooves on their surfaces, and existing cooling devices are limited by the structure of the nozzles, making it impossible to achieve uniform cooling of the entire surface of the aluminum profile. This reduces the uniformity of cooling the aluminum profile surface and lowers the cooling efficiency.

[0007] Secondly, after aluminum profiles are cooled with cooling water, a large amount of liquid tends to adhere to their surface, causing it to drip into the surrounding environment and affecting the cleanliness of the working environment.

[0008] As can be seen from the above, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a rapid cooling device for aluminum profile production. This device solves the problems of traditional cooling methods where the grooved surface of aluminum profiles limits the ability of existing cooling devices to uniformly cool the entire surface, reducing cooling uniformity and efficiency. Furthermore, it addresses the issue that after cooling with water, a large amount of liquid adheres to the aluminum profile surface, dripping into the surrounding environment and affecting the cleanliness of the workspace.

[0010] To achieve the above objectives, the present invention provides the following technical solution.

[0011] A rapid cooling device for aluminum profile production includes a cleaning housing. Opposite ends of the cleaning housing have opposing inlets and outlets, forming an aluminum profile movement channel between the two inlets and outlets. Inside the cleaning housing, along the feeding direction of the aluminum profile, a spray assembly and a blowing assembly are sequentially arranged.

[0012] The spray assembly includes several annular spray pipes arranged side by side along the feeding direction of the aluminum profile. The aluminum profile passes through the inner hole of the annular spray pipe, and several spray nozzles are arranged around the inner ring of the annular spray pipe.

[0013] The blowing assembly includes several annular blowing pipes arranged in parallel along the feeding direction of the aluminum profile. The aluminum profile passes through the inner hole of the annular blowing pipes, and several blowing nozzles converging towards the center are arranged on the side wall of the several annular blowing pipes facing the annular blowing pipe.

[0014] As an optimized solution, several rollers are arranged in parallel and rotate horizontally inside the cleaning housing, and an installation area is formed through the area between adjacent rollers. Several annular blowpipes and annular spray pipes are located in the installation area.

[0015] As an optimized solution, the spray nozzles on adjacent annular spray pipes are arranged in a staggered manner along the circumference.

[0016] As an optimized solution, the nozzles on adjacent annular jet pipes are arranged in a staggered manner along the circumference.

[0017] As an optimized solution, a filter housing is fixedly connected to the side wall of the cleaning housing near the bottom, and a drain hole is opened between the filter housing and the cleaning housing. Several layers of filter cotton are laid in parallel from top to bottom inside the filter housing.

[0018] As an optimized solution, a support mesh plate is horizontally fixed inside the filter housing, and the lower surface of the filter cotton is supported on the support mesh plate.

[0019] As an optimized solution, a drain cylinder is fixedly connected to the lower end of the filter housing.

[0020] As an optimized solution, the upper end of the filter housing is provided with an opening.

[0021] As an optimized solution, the upper surface of the filter cotton is lower than the lower edge of the drain hole.

[0022] As an optimized solution, the upper ends of the annular spray pipe and the annular blow pipe are respectively connected with clamps, the clamps are fixed to a hanger rod, the upper end of the hanger rod is fixed to a connecting plate, and the connecting plate is fixed to the inner top surface of the cleaning housing by bolts.

[0023] As an optimized solution, the lower ends of several annular blowpipes are vertically fixed with air inlet pipes that communicate with their inner cavities. The inlet ends of several air inlet pipes extend to the outside of the cleaning housing and are connected together to the main air distribution pipe, on which an air inlet cylinder is fixed.

[0024] As an optimized solution, each of the intake pipes is connected to an intake regulating valve.

[0025] As an optimized solution, the lower ends of several annular spray pipes are vertically fixed with inlet pipes that communicate with their inner cavities. The inlet ends of several inlet pipes extend to the outside of the cleaning housing and are connected together to the liquid distribution main pipe, which is fixed with an inlet cylinder.

[0026] As an optimized solution, each of the inlet pipes is connected to an inlet regulating valve.

[0027] As an optimized solution, the upper surface of the idler roller is higher than the lower edge of the inlet and outlet.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] By cleaning the housing, the aluminum profile enters the housing and achieves a relatively sealed treatment. Several annular spray pipes are arranged in parallel along the feeding direction of the aluminum profile, and several spray nozzles arranged in a ring shape are used to uniformly spray and cool the surface of the aluminum profile, thereby improving the uniformity of coverage and spraying.

[0030] After the aluminum profile is cooled by the spray from the annular spray pipe, it passes through the annular blow pipe. The annular blow pipe has several nozzles that are tilted and converge towards the center to supply high-pressure air, which is then sprayed at an angle towards the surface of the aluminum profile. This blows off the cooling water adhering to the surface of the aluminum profile, preventing a large amount of cooling water from dripping into the surrounding environment and ensuring the cleanliness of the surrounding working environment.

[0031] After heat exchange with the aluminum profile, the cooling water drips into the cleaning housing for collection. It then enters the filter housing through the drain hole and passes through several layers of filter cotton to filter out impurities and particles in the cooling water. The filtered cooling water is discharged through the drain cylinder. The cleaning housing has an opening at the top end for easy and quick removal and replacement of the filter cotton.

[0038] The spraying assembly includes several annular spray pipes 6 arranged in parallel along the feeding direction of the aluminum profile 3. The aluminum profile 3 passes through the inner hole of the annular spray pipe 6. Several spray nozzles 7 that converge toward the center are arranged around the side wall of the several annular spray pipes 6 facing the annular spray pipe 4.

[0039] Inside the cleaning housing 1, several rollers 8 are arranged in parallel and rotate in the horizontal direction, and an installation area is formed through the area between adjacent rollers 8. Several annular blow pipes 6 and annular spray pipes 4 are located in the installation area.

[0040] The spray nozzles 5 on adjacent annular spray pipes 4 are arranged in a staggered manner along the circumference to compensate for the gap between adjacent nozzles.

[0041] The nozzles 7 on adjacent annular jet pipes 6 are arranged in a staggered manner along the circumference.

[0042] A filter housing 17 is fixedly attached to the side wall near the bottom of the cleaning housing 1. A drain hole 18 is provided between the filter housing 17 and the cleaning housing 1. Several layers of filter cotton 20 are laid side by side from top to bottom inside the filter housing 17.

[0043] A support mesh plate 19 is horizontally fixed inside the filter housing 17, and the lower surface of the filter cotton 20 is supported on the support mesh plate 19.

[0044] A drain cylinder 21 is fixedly connected to the lower end of the filter housing 17.

[0045] The filter housing 17 has an opening at the top end to facilitate the replacement of the filter cotton 20.

[0046] The upper surface of the filter cotton 20 is lower than the lower edge of the drain hole 18.

[0047] The upper ends of the annular spray pipe 4 and the annular blow pipe 6 are respectively connected with clamps, and the clamps are fixed to the hangers. The upper end of the hangers is fixed to the connecting plate, and the connecting plate is fixed to the inner top surface of the cleaning housing 1 by bolts.

[0048] The lower ends of several annular blowpipes 6 are vertically fixed with air inlet pipes 13 that connect to their inner cavities. The inlet ends of several air inlet pipes 13 extend to the outside of the cleaning housing 1 and are connected to the main air distribution pipe 14. An air inlet cylinder 15 is fixed to the main air distribution pipe 14.

The annular blow pipe 6 has several nozzles 7 that are tilted and converge towards the center, which supply high-pressure air and spray it at an angle towards the surface of the aluminum profile 3. This blows off the cooling water adhering to the surface of the aluminum profile 3, preventing a large amount of cooling water from dripping into the surrounding environment and ensuring the cleanliness of the surrounding working environment.

[0057] After heat exchange with the aluminum profile 3, the cooling water drips into the cleaning housing 1 for collection. It then enters the filter housing 17 through the drain hole 18 and passes through several layers of filter cotton 20 to filter impurities and particles in the cooling water. The filtered cooling water is discharged through the drain cylinder 21. The upper end of the cleaning housing 1 is open to facilitate the removal and replacement of the filter cotton 20, which is convenient and quick.
