[0002] Aluminum alloy profiles are the most widely used type of non-ferrous metal structural materials in industry. They have been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. Aluminum alloy profiles have the characteristics of novel structure, reasonable process and excellent performance. They can be mainly divided into two categories: cast aluminum alloy profiles and deformed aluminum alloy profiles. Cast aluminum alloy profiles are produced by melting and casting. After casting, they can be further processed into aluminum alloy materials of various shapes and sizes; deformed aluminum alloy profiles are made by first melting the alloy ingredients into billets, and then performing plastic deformation processing. Various plastic processed products are made through rolling, extrusion, stretching, forging and other methods.

[0003] Aluminum alloy profiles will generate a large amount of waste heat during the heat treatment process. Heat pipe technology, as an efficient heat transfer method, is widely used in the field of waste heat recovery. However, impurities such as scale are easily accumulated in the heat pipe during use, resulting in a decrease in heat transfer efficiency and even equipment failure. Therefore, how to effectively clean the dust on the heat pipe and maintain its good heat transfer performance has become an urgent problem to be solved in the current field of heat treatment equipment.

[0021] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A heat treatment equipment for aluminum alloy profiles includes a heat treatment equipment body 1, a heat exhaust pipe 2, a front heat exhaust pipe 3 and a rear heat exhaust pipe 4. A heat exhaust pipe 2 is arranged on one side of the heat treatment equipment body 1, and the front heat exhaust pipe 3 and the rear heat exhaust pipe 4 are respectively arranged at both ends of the heat exhaust pipe 2. A water inlet 5 is opened above the front heat exhaust pipe 3, and the water inlet 5 is connected to the inside of the heat treatment equipment body 1. A water outlet 6 is opened below the front heat exhaust pipe 3. A plurality of internal heat pipes 9 are fixed inside the heat exhaust pipe 2, and baffles 10 are fixed at both ends of each internal heat pipe 9. A connecting rod 11 is rotatably connected between every two opposite baffles 10. A spiral fan blade 14 is fixed at one end of the connecting rod 11 close to the front heat exhaust pipe 3. Three cleaning rings 12 are equidistantly rotatably sleeved at both ends and the middle of the connecting rod 11. Two first cleaning rods 13 are symmetrically fixed on the three cleaning rings 12, so that the scale on the inner wall of the internal heat pipe 9 is convenient to clean.

[0023] Specifically, the outer sides of the first cleaning rod 13 and the cleaning ring 12 fit the inner wall of the inner heat pipe 9, and the radius of the inner heat pipe 9 is equal to the radius of the inner circle of the cleaning ring 12, so that the water flow pushes the inner heat pipe 9 to drive the connecting rod 11 to rotate.

[0024] As an optimization solution, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a servo motor 15 is fixed on one end of the heat exhaust rear pipe 4 away from the heat exhaust pipe 2, and the output end of the servo motor 15 extends to the inside of the heat exhaust rear pipe 4. A second cleaning rod 7 is fixed to the output end of the servo motor 15, so that the second cleaning rod 7 cleans the scale inside the heat exhaust rear pipe 4. A sealing rubber is provided at the connection between the output end of the servo motor 15 and the heat exhaust rear pipe 4, and the outer side of the second cleaning rod 7 fits against the inner wall of the heat exhaust rear pipe 4 to prevent the heat exhaust rear pipe 4 from depressurizing.

[0025] Specifically, a recovery box 8 is fixed inside the water outlet 6, a groove matching the shape of the recovery box 8 is opened inside the water outlet 6, a filter is provided at the bottom of the recovery box 8, and the recovery box 8 is fixed to both sides of the outside of the water outlet 6 by bolts, which is convenient for the staff to clean the recovery box 8.

[0026] Working principle: When the hot water inside the heat treatment equipment body 1 flows into the upper part of the front heat exhaust pipe 3 through the water inlet 5, the water flows into the inner heat pipe 9 above the heat exhaust pipe 2. At this time, the heat exhaust pipe 2 recovers the heat from the inner heat pipe 9 through the heat recovery port above. When the water flows into the inner heat pipe 9, the water flows push the spiral blades 14 to rotate, so that the spiral blades 14 drive the connecting rod 11 to rotate. The connecting rod 11 rotates and drives the cleaning ring 12 to rotate, so that the cleaning ring 12 drives the first cleaning rod 13 to rotate, so that the first cleaning rod 13 scrapes the scale on the inner wall of the inner heat pipe 9. When the water flows into the inner heat pipe 9, the spiral blades 14 drive the connecting rod 11 to rotate. When the impurities flow into the rear heat exhaust pipe 4, the servo motor 15 is started, so that the servo motor 15 drives the second cleaning rod 7 to rotate, so that the second cleaning rod 7 scrapes the scale on the inner wall of the rear heat exhaust pipe 4. At the same time, the rotating second cleaning rod 7 stirs the water flow inside the rear heat exhaust pipe 4 to prevent the impurities from being deposited inside the rear heat exhaust pipe 4. The water flow carrying impurities enters the bottom of the front heat exhaust pipe 3 through the inner heat pipe 9 under the heat exhaust pipe 2 and is discharged through the water outlet 6. At the same time, the recovery box 8 screens out impurities such as scale. The recovery box 8 is taken out for cleaning after the fixing between the recovery box 8 and the water outlet 6 is released by the bolts at both ends.
