Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy quenching furnaces, and in particular to a rapid water cooling and heat recovery device for aluminum alloy quenching furnaces. Background Technology

[0002] An aluminum alloy quenching furnace is a device specifically designed for the heat treatment of aluminum alloy materials. Its main function is to change the crystal structure of aluminum alloys through heating and rapid cooling, thereby improving their key properties such as hardness and elongation.

[0003] Aluminum alloy quenching furnaces are required when processing aluminum alloys. However, current aluminum alloy quenching furnaces are difficult to use for rapid water cooling of aluminum alloys, which will reduce the hardness of the aluminum alloys. In addition, a large amount of heat energy is generated during the quenching process, which is difficult to recover and reuse, resulting in energy waste. To address these issues, we propose a rapid water cooling and heat recovery device for aluminum alloy quenching furnaces. Utility Model Content

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5This utility model discloses a rapid water cooling and heat recovery device for an aluminum alloy quenching furnace, comprising a platform 1, a quenching mechanism 2 on the outside of the platform 1, a placement rack 3 fixedly mounted on the upper surface of the platform 1, a water storage tank 4 fixedly mounted on the upper surface of the platform 1, a water pump 5 fixedly mounted on the upper surface of the platform 1, the input end of the water pump 5 penetrating through the water storage tank 4 and extending into the interior of the water storage tank 4, the output end of the water pump 5 being fixedly connected to a connecting pipe 6, the end of the connecting pipe 6 away from the water pump 5 being fixedly connected to a spray pipe 7, the outer surface of the spray pipe 7 being fixedly connected to multiple nozzles 8, a square opening 9 on the upper surface of the platform 1, a connecting cover 10 fixedly mounted on the bottom surface of the platform 1, a hot water tank 11 fixedly mounted on the bottom surface of the platform 1, a discharge pipe 12 fixedly connected to the bottom end of the connecting cover 10, a one-way valve 13 fixedly connected to the outer surface of the discharge pipe 12, and the discharge pipe 12... The end away from the connecting cover 10 passes through the hot water tank 11 and extends into the interior of the hot water tank 11. Through the setting of the quenching mechanism 2, the aluminum alloy workpiece can be heated. The two heating methods work together to quickly heat the aluminum alloy workpiece to the appropriate quenching temperature. The set water pump 5 draws cooling water from the water storage tank 4 and sprays it onto the aluminum alloy workpiece through the connecting pipe 6, the spray pipe 7 and multiple nozzles 8, which can quickly cool the aluminum alloy workpiece with water. This can make the aluminum alloy workpiece form an ideal microstructure and effectively improve the hardness and strength of the aluminum alloy workpiece. Through the setting of the square opening 9, the water that has absorbed the heat of the aluminum alloy workpiece and heated up can flow into the connecting cover 10 and enter the interior of the hot water tank 11 through the discharge pipe 12 to recover and store the heat energy, thus solving the energy waste caused by directly discharging hot water.

[0025] The quenching mechanism 2 includes a carrier plate 206 fixedly connected to the left and right sides of the platform 1. An electric push rod 201 is fixedly installed on the upper surface of each carrier plate 206. A moving plate 202 is fixedly installed on the telescopic end of each of the two electric push rods 201. A quenching shell 203 is fixedly installed on the side of the two moving plates 202 that are close to each other. A resistance wire 204 is provided on the inner wall of the quenching shell 203. An induction coil 205 is provided on the inner top wall of the quenching shell 203. The resistance wire 204 generates heat through current and heats the workpiece uniformly through thermal radiation and thermal conduction. The induction coil 205 uses the principle of electromagnetic induction to generate an induced current inside the aluminum alloy workpiece, thereby generating heat. By using the quenching mechanism 2, the two electric push rods 201 can be activated to retract, which can drive the two moving plates 202 and the quenching shell 203 to move downwards. The quenching shell 203 can be moved to a suitable position, and the heating work can be carried out by activating the resistance wire 204 and the induction coil 205, so as to perform quenching treatment on the aluminum alloy inside the quenching shell 203.

[0026] Two sets of support legs 14 are fixedly connected to the bottom surface of the platform 1. A PLC controller 15 is fixedly installed on the front of the quenching shell 203. Stabilizing blocks 16 are fixedly installed on the bottom surfaces of the two moving plates 202. The sides of the two stabilizing blocks 16 that are close to each other are fixedly installed to the outer surface of the quenching shell 203. A connecting pipe 20 is fixedly connected to the bottom surface of the hot water tank 11. A solenoid valve 21 is fixedly connected to the outer surface of the connecting pipe 20. A groove 17 is opened on the upper surface of the platform 1. A baffle 18 is fixedly installed on the upper surface of the water storage tank 4. A water inlet 19 is opened on the upper surface of the water storage tank 4. Two sets of support legs 14 can support the device, and the PLC controller 15 can regulate the device. Two stabilizing blocks 16 can make the quenching shell 203 more stable. The connecting pipe 20 and solenoid valve 21 can connect to external hot water equipment and quickly discharge hot water, and transport the stored hot water to other links that require heat energy. The quenching shell 203 can be lowered into the tank 17 to make it more stable. The baffle 18 can block the sprayed cooling water, and the water inlet 19 can inject cooling water into the water storage tank 4.

[0027] The working principle of this utility model is as follows:

[0028] First, connect the device to the power supply and place the aluminum alloy workpiece on the placement rack 3. At the same time, start the two electric push rods 201 to retract and drive the two moving plates 202 and the quenching shell 203 to move downward, covering the aluminum alloy workpiece inside the quenching shell 203. At this time, the aluminum alloy workpiece is heated by the resistance wire 204 and the induction coil 205. The two heating methods work together to quickly heat the aluminum alloy workpiece to the appropriate quenching temperature.

[0029] Once the aluminum alloy workpiece reaches the quenching temperature, the heating of the resistance wire 204 and induction coil 205 is stopped, and the two electric push rods 201 are activated to move the two moving plates 202 and the quenching shell 203 upwards, exposing the aluminum alloy workpiece. At the same time, the water pump 5 is activated to draw cooling water from the water storage tank 4, which is then sprayed out through the connecting pipe 6, the spray pipe 7, and multiple nozzles 8 to quickly cool the aluminum alloy workpiece. The sprayed cooling water absorbs the heat from the aluminum alloy workpiece and its temperature rises, turning into hot water. The hot water flows through the square opening 9 into the connecting cover 10, and then enters the hot water tank 11 through the discharge pipe 12. The one-way valve 13 is used to prevent the hot water from flowing back, thus realizing the recovery of heat energy. Then, the stored hot water is transported to other links that require heat energy through the connecting pipe 20 and the solenoid valve 21.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
