Description

Technical Field

[0001] The present application relates to the technical field of waste heat recovery, and in particular to a waste heat recovery device for quenching aluminum alloy profiles. Background Art

[0002] In the quenching process of stainless steel profiles, waste heat recovery usually occurs in the rapid cooling stage. In the rapid cooling stage, the profile is cooled very quickly to obtain a martensitic structure. In the above process, the cooling medium contacts the profile and performs heat exchange. After that, waste heat can be recovered by introducing the cooling medium into a heat exchange device. The heat exchange device is usually provided with a heat pipe or fins for heat exchange. The cooling medium transfers its own heat to the heat exchange medium at the other end of the heat pipe through the heat pipe, completing the waste heat recovery process.

[0003] During the rapid cooling process of the profile, the lubricating oil on the surface of the stainless steel profile falls off, causing some grease and organic matter to be carried in the cooling medium. After these organic matter enters the heat exchange device, they will adhere to the wall surface of the device. The heat insulation properties of the grease or organic matter themselves will affect the heat transfer efficiency of the cooling medium. Therefore, it is necessary to clean the grease in the heat exchange device regularly.

[0004] Using metal soluble electrodes to treat the cooling medium can effectively remove grease and organic matter. When the electrode is energized, the anode will dissolve and release metal ions. The metal ions react with the hydroxyl groups in the water to form complexes and hydroxide flocs; this floc has a strong adsorption capacity and can adsorb suspended particles and emulsified oil droplets in the cooling medium, that is, an electro-flocculation reaction. At the same time, the anode and cathode will form microbubbles in the cooling medium, which will adhere to the flocs and make them float on the liquid surface. Finally, the flocs can be removed by filtering through a filter; at the same time, since there are some metal particles in the cooling medium, they can also be removed by membrane filtration.

[0005] When using soluble electrodes to treat grease in wastewater, some grease will adhere to the surface of the electrode after long-term use, so the electrode needs to be cleaned regularly. However, since the electrode is in a high-temperature environment, it is inconvenient to disassemble and clean it; at the same time, downtime for maintenance will also cause heat loss in the cooling medium. Although regular disassembly and maintenance of the electrode can solve the problem of heat loss, it also requires labor costs, and frequent disassembly and cleaning of the electrode will also cause the electrode to consume its service life faster. Therefore, it is necessary to set up a device for automatic detection and cleaning of the electrode in the electrolytic cell. Summary of the invention

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-8 This application is described in further detail.

[0031] The present application discloses a device for recovering residual heat from quenching of aluminum alloy profiles. Figure 1 , a waste heat recovery device for decorative paper production includes an electrolytic cell 1. After quenching, the cooling medium is introduced into the electrolytic cell 1. An anode column 2 and a cathode column connected to the positive and negative electrodes of the power supply are respectively provided in the electrolytic cell 1. It should be noted that the cooling medium is water; the material of the anode column 2 is iron or aluminum. During the electrolysis process, the anode column 2 gradually dissolves in the cooling medium and releases metal ions, which are used to remove grease or organic matter in the cooling medium.

[0032] Reference Figure 2, there are multiple anode columns 2 in the electrolytic cell 1. A cleaning chamber 3 for cleaning the anode column 2, a storage chamber 11 for removing the cleaning liquid on the anode column 2, and a detection chamber 4 for detecting the electrolytic ability of the anode column 2 are arranged in the wall of the electrolytic cell 1. A motor 1 is buried in the top wall of the electrolytic cell 1; the motor 1 is a stepping motor, and the output shaft of the motor 1 is arranged toward the electrolytic cell 1. A rotating wheel 5 is fixed at the end of the output shaft of the motor 1, and the anode column 2 is arranged on the lower end surface of the rotating wheel 5. Specifically, four anode columns 2 are arranged on the lower end surface of the rotating wheel 5, and the angle between the adjacent anode columns 2 and the center of the rotating wheel 5 is 90°; the anode column 2 can be moved on the lower end surface of the rotating wheel 5 for replacing the anode column 2. The cleaning chamber 3, the storage chamber 11 and the detection chamber 4 are arranged below the rotating wheel 5, and the angle between the two adjacent chambers is 90°. An arc-shaped corridor 12 is opened between the two adjacent chambers for the anode column 2 to pass through.

[0033] Reference Figure 3 , four slide tubes 21 for accommodating the anode column 2 are provided at the bottom of the rotating wheel 5, and the anode column 2 is vertically slidably arranged in the slide tube 21. A limit ring 22 is integrally formed on the inner circumference of the bottom end of the slide tube 21 to prevent the anode column 2 from escaping from the slide tube 21. An electromagnet 23 is fixedly provided on the top surface of the slide tube 21; a metal sheet that can be magnetically attracted to the electromagnet 23 is fixedly provided on the top of the anode column 2; after the electromagnet 23 is energized, the anode column 2 is raised by absorbing the metal sheet, so that the anode column 2 follows the slide tube 21 through the passage 12 to move to the adjacent chamber. When the electromagnet 23 is not energized, the anode column 2 is below the slide tube 21, and at this time the anode column 2 can contact the liquid in the electrolytic cell 1 or the corresponding chamber.

[0034] Reference Figure 4 and Figure 5 , the switch for controlling the on and off of the electromagnet 23 is arranged on the top surface of the rotating wheel 5. A switch slot 51 is provided on the top surface of the rotating wheel 5; a slider 52 is provided in the switch slot 51 for vertical sliding. A compression spring 53 is fixed in the switch slot 51, and the compression spring 53 is fixedly connected to the slider 52, and is used to drive the slider 52 to reset upward. An annular clearance slot 13 is provided on the top wall of the electrolytic cell 1, and the clearance slot 13 extends into the cell wall of the electrolytic cell 1 and covers the rotation track of the rotating wheel 5. When the compression spring 53 is in a natural expansion and contraction state, the slider 52 extends into the clearance slot 13.

[0035] Reference Figure 4, four contacts 14 are evenly distributed in the give way groove 13. The angle between two adjacent contacts 14 and the center of the wheel 5 is 90°; the four contacts 14 are respectively located in the electrolytic cell 1 and the three chambers. The contact 14 is a hemispherical protrusion; the top surface of the slider 52 is fixed with a hemispherical protrusion, which is convenient for contracting downward after contacting with the contact 14. The side wall of the slider 52 is fixed with a switch movable plate 15 electrically connected to the electromagnet 23, and the inner wall of the switch groove 51 is fixed with a switch fixed plate 1 electrically connected to the power supply; when the compression spring 53 is in a natural expansion and contraction state, the switch movable plate 15 is in electrical contact with the switch fixed plate 1, and the electromagnet 23 is energized; after the slider 52 contacts the contact 14, it is pressed to move toward the inside of the switch groove 51, and the electromagnet 23 is de-energized.

[0036] A contact switch is provided between the slide tube 21 and the rotating wheel 5. The contact switch includes a contact stator fixed on the rotating wheel 5 and a contact movable plate 24 fixed on the slide tube 21. Specifically, four contact stators are fixed on the bottom surface of the rotating wheel 5, and the contact stators are located above the slide tube 21; a contact movable plate 24 is fixed on the top surface of the slide tube 21. The contact switch is connected to the connection circuit of the electromagnet 1 23.

[0037] Specifically, after the controller of the stepper motor is powered on, a pulse signal is output to the stepper motor, causing the output shaft of the stepper motor to rotate 90° and then stop rotating; when the output shaft of the stepper motor stops rotating, the slider 1 52 is located below the contact 14 .

[0038] A power supply stator 1 and a power supply stator 2 are fixedly provided at the bottom of the inner circumference of the slide tube 21; the power supply stator 1 and the power supply stator 2 are electrically connected to two power supplies respectively. A power supply movable plate 1 and a power supply movable plate 2 are fixedly provided at the top of the anode column 2, which are respectively conductive to the anode column 2. After the anode column 2 slides down to the bottom of the slide tube 21, the power supply movable plate 1 is electrically contacted with the power supply stator 1, and the power supply movable plate 2 is electrically contacted with the power supply stator 2. After the power supply movable plate 1 is electrically contacted with the power supply stator 1, the circuit formed by the anode column 2 and the cathode column is conductive, and the anode column 2 releases metal ions into the cooling medium; the power supply movable plate 2 and the power supply stator 2 are connected to the detection circuit, and after the power supply movable plate 2 is electrically contacted with the power supply stator 2, the signal released by the detection circuit controls the motor 1 to start. The detection circuit includes an electrically connected comparator and a relay 1, and the relay 1 is connected to the controller of the stepper motor.

[0039] Specifically, the power supply stator 2 is connected to the power supply and the comparator respectively; a shunt resistor is connected between the power supply stator 2 and the power supply; and the other input terminal of the comparator is connected to the reference voltage. The output terminal of the comparator is connected to the coil of the relay 1. The controller of the stepper motor is connected to the normally closed contact 14 of the relay 1. After the power supply moving plate 2 and the power supply stator 2 are closed, the comparator measures the actual voltage in the circuit and compares it with the reference voltage. When the actual current is lower than the threshold current, the comparator outputs a low level to the relay 1; the relay 1 starts the controller, and the controller outputs a pulse signal to the stepper motor. After the rotating wheel 5 rotates, the slider 1 52 is separated from the contact 14, the electromagnet 1 23 is energized and produces an adsorption effect on the anode column 2, so that the anode column 2 rises. A delayed power-off function is set in the controller, so that the stepper motor controls the rotating wheel 5 to stop after rotating a unit number of circles.

[0040] It should be noted that the power supply stator 1 and the power supply stator 2 are respectively provided with control switches on the connection circuits with the power supply. Both sets of control switches are arranged between the top wall of the electrolytic cell 1 and the rotor 5. Specifically, four control moving plates are fixedly arranged on the top surface of the rotor 5, and a control stator connected to the power supply is fixedly arranged on the top wall of the electrolytic cell 1. The control stator is arranged inside the top wall of the cell chamber of the electrolytic cell 1, and the control moving plate on the rotor 5 that rotates into the cell chamber 1 can be in electrical contact with the control stator. The control switch is electrically connected to the contact switch, and the slide tube 21 is located at a preset position below the rotor 5 and is located in the cell chamber of the electrolytic cell 1 to make the cathode column and the detection circuit conductive.

[0041] Reference Figure 6 and Figure 7 , a liquid inlet pipe 1 and a liquid outlet pipe 1 are fixedly provided in the cleaning chamber 3, which are used to input and output cleaning liquid, such as ethanol solution, into and out of the cleaning chamber 3. It should be noted that the contacts 14 in the electrolytic cell 1, the storage chamber 11 and the detection chamber 4 are all fixedly connected to the top wall, and the contacts 14 in the cleaning chamber 3 are slidably arranged in the top wall of the cleaning chamber 3. Specifically, a chute 2 31 is provided in the top wall of the cleaning chamber 3; a slider 2 32 is vertically slidably arranged in the chute 2 31. An electromagnet 2 33 and a reset spring 1 34 are fixedly provided on the inner top wall of the chute 2 31; a metal sheet that can be magnetically adsorbed by the electromagnet 2 33 is fixedly provided on the top surface of the slider 2 32; the reset spring 1 34 is fixedly connected to the slider 2 32, which is used to push the slider 2 32 to move to the outside of the chute 2 31. After the electromagnet 2 33 is energized, the slider 2 32 slides upward by adsorbing the metal sheet. The contact 14 is fixedly provided at the bottom of the slider 2 32, and after the slider 2 32 moves upward, the contact 14 is separated from the slider 1 52. It should be noted that when the return spring 1 34 is in a naturally stretched state, the slider 1 52 is pressed and moves downward after contacting the contact 14 .

[0042] Reference Figure 7, a switch assembly for controlling the on and off of the electromagnet 2 33 is arranged on the top wall of the cleaning chamber 3. The switch assembly includes a sliding hole 35 opened on the top wall of the cleaning chamber 3, and a slider 3 36 is arranged in the sliding hole 35 along the vertical sliding direction. A switch moving piece 2 37 is fixed on the outer peripheral surface of the slider 3 36, and a switch stator 2 that can be in electrical contact with the switch moving piece 2 37 is fixed on the side wall of the sliding hole 35. A reset spring 2 38 is fixed in the sliding hole 35, and the reset spring 2 38 is fixed to the slider 3 36 to drive the slider 3 36 to reset downward; when the reset spring 2 38 is in a natural expansion state, the switch moving piece 2 37 is in electrical contact with the switch stator 2. Four slots 54 that can be respectively plugged into the slider 3 36 are opened on the top surface of the rotating wheel 5, and the four slots 54 are respectively located above the anode column 2. Specifically, after the rotating wheel 5 stops rotating, the slider 3 36 is inserted into the slot 54, so that the switch moving piece 2 37 is in electrical contact with the switch stator 2. The switch moving piece 2 37 is electrically connected to the electromagnet 2 33, and the switch fixed piece 2 is electrically connected to the power supply. The bottom surface of the slider 3 36 is provided with a spherical surface, so that the slider 3 36 can leave the slot 54 after the rotating wheel 5 rotates.

[0043] Specifically, the control circuit of the second electromagnet 33 is provided with a timer 1 and a relay 2; the output end of the timer 1 is connected to the coil of the second relay, and the second electromagnet 33 is connected to the normally closed contact 14 of the second relay. After the second switch moving piece 37 is in electrical contact with the second switch fixed piece, the timer starts timing; after the timer 1 finishes timing, it outputs a low level to the second relay, and the second relay controls the second electromagnet 33 to start. After the second electromagnet 33 is started, the slider 3 36 is attracted to rise; the slider 2 32 that loses the pressing effect is reset upward under the action of elasticity, so that the first electromagnet 23 is started; the anode column 2 is magnetically attracted to rise and leave the cleaning liquid, so that the anode column 2 ends the soaking after the unit time.

[0044] Reference Figure 2 The storage chamber 11 is provided with a second liquid inlet pipe and a second liquid outlet pipe for inputting distilled water into the storage chamber 11 for further cleaning the anode. It should be noted that the second liquid inlet pipe continuously inputs distilled water into the storage chamber 11, and the second liquid outlet pipe continuously discharges the distilled water in the storage chamber 11.

[0045] Reference Figure 8 , a weighing structure for weighing the anode column 2 is arranged in the detection chamber 4. The weighing structure includes a bottom hole 41 opened in the bottom surface of the detection chamber 4 and a weighing rod 42 vertically slidably arranged in the bottom hole 41, and a weighing platform 43 is fixedly connected to the top of the weighing rod 42. A compression spring 2 44 is fixedly arranged between the weighing platform 43 and the bottom surface of the detection chamber 4, which is used to drive the weighing platform 43 to reset upward; after the anode column 2 contacts the weighing platform 43, it will press the weighing platform 43 to move downward. A power supply moving plate 3 45 is fixedly connected to the bottom surface of the weighing rod 42; a power supply stator 3 that can electrically contact the power supply moving plate 3 45 is fixedly arranged on the inner circumference of the bottom hole 41.

[0046] Specifically, during the use of the anode column 2, the metal cations are precipitated into the cooling medium, resulting in a reduction in its own weight. When its own weight reaches the weight threshold, the anode column 2 needs to be replaced. After the anode column 2 contacts the weighing platform 43, the actual weight is too large due to the distilled water on the surface of the load itself. A vent is provided in the detection chamber 4 to accelerate the air flow in the detection chamber 4 and air dry the anode column 2. After the weighing platform 43 contacts the anode column 2, it moves downward. As the moisture on the outer surface of the anode column 2 is dried and the weight is reduced, it will reset upward under the action of the compression spring 2 44. When the compression spring 2 44 is naturally stretched, the power supply stator 3 is located below the power supply movable plate 3 45. When the weight of the anode column 2 does not reach the weight threshold, the anode column 2 presses against the weighing platform 43 and drives the power supply movable plate 3 45 to move below the power supply stator 3. As the moisture on the outer surface of the anode column 2 is gradually dried, the power supply movable plate 3 45 gradually moves upward following the weighing rod 42. If the weight of the anode column 2 reaches the weight threshold, the power supply movable plate 3 45 moves upward to electrically contact the power supply stator 3.

[0047] Reference Figure 2 and Figure 3 A cylindrical spare cabin 6 for placing spare anode columns 2 is fixedly arranged on the bottom surface of the rotating wheel 5. Four spare chambers 61 are provided on the outer circumference of the spare cabin 6, and the four spare chambers 61 are respectively aligned with the four slide tubes 21. The spare cabin 6 is rotatably arranged in the wall of the electrolytic cell 1; a through hole is provided on the inner wall of the detection chamber 4, which is used for the spare cabin 6 to align with the spare chamber 61 after the rotation stops. Four groups of transmission components for moving the slide tube 21 are evenly distributed at the bottom of the rotating wheel 5. Specifically, the transmission component includes two sprocket wheels 63 rotatably arranged on the bottom surface of the rotating wheel 5, and chains 64 are provided around the two sprocket wheels 63. The slide tube 21 is fixed to the outer circumference of the chain link 62 of the chain 64, and the two slide tubes 21 are arranged in alignment.

[0048] Specifically, a second motor is embedded in the top wall of the standby chamber 61, and the second motor is a stepping motor. The output shaft of the second motor is coaxially fixedly connected to one of the sprockets 63. After the controller of the second motor is powered on, a pulse signal is output to the second motor, and the second motor drives the sprocket 63 to rotate a unit number of circles, so that the slide tube 21 in the standby chamber 61 rotates to below the contact 14. The top surface of the weighing table 43 is a round table surface, which is convenient for the anode column 2 to contact the weighing table 43 during the movement process.

[0049] The control circuit of motor 2 is provided with timer 2 and relay 3. Specifically, the output end of timer 2 is electrically connected to the coil of relay 3, and the controller of motor 2 is connected to the normally closed contact 14 of relay 3. Power rotor 3 45 is connected to the output end of timer 2, and power stator 3 is electrically connected to the power supply. When power rotor 3 45 is in electrical contact with power stator 3, timer 2 starts timing; after timer 2 ends timing, it outputs a low level to relay 3, and relay 3 controls the controller of motor 2 to start; the controller outputs a pulse signal to motor 2, so that motor 2 controls sprocket 63 to rotate a unit number of turns. It should be noted that a delayed power-off function is set in the controller, so that the stepper motor controls the rotating wheel 5 to stop after rotating a unit number of turns.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
