As shown in fig. 1, 2 and 6, one embodiment of the present disclosure provides an aluminum liquid transfer system including a melting furnace 1, a dosing furnace 2 for supplying aluminum liquid to a die casting machine 3, a transfer passage 4, and a first pumping device 5. Wherein, the quantitative furnace 2 is provided with a liquid amount monitoring device 21 for monitoring the liquid amount of the aluminum liquid in the quantitative furnace 2 in real time; the transfer channel 4 is communicated between the melting furnace 1 and the quantifying furnace 2 and is used for transferring aluminum liquid from the melting furnace 1 into the quantifying furnace 2; the first pumping means 5 are in communication with the liquid amount monitoring means 21 for pumping the aluminium liquid in the melting furnace 1 to the dosing furnace 2 via the transfer channel 4 when the liquid amount in the dosing furnace 2 is smaller than a preset value. It should be noted that the "communication connection" between the first pumping device 5 and the liquid amount monitoring device 21, and other communication connections to be described below include the liquid amount monitoring device 21 transmitting data to the controller, and the controller sending control instructions to the first pumping device 5, which may be implemented by respective independent or integrated controllers, so long as it is ensured that the executing element (e.g., the first pumping device 5) executes the action according to the instruction corresponding to the feedback signal from the signal acquiring element (e.g., the liquid amount monitoring device 21), and the specific configuration of the embodiment of the present disclosure is not limited.
Through the above technical scheme, in the embodiment of the disclosure, the transfer channel 4 is arranged between the melting furnace 1 and the quantifying furnace 2, and compared with the form of batch transfer of transfer bags in the related art, the method can simplify the processing flow, improve the transmission efficiency, reduce the transportation cost and greatly reduce the occupied area of the production line.
Meanwhile, as the liquid amount monitoring device 21 is arranged in the quantitative furnace 2, when the liquid amount in the quantitative furnace 2 is smaller than a preset value, the aluminum liquid in the melting furnace 1 can be supplied to the quantitative furnace 2 through the first pumping device 5, the first pumping device 5 can be opened or closed according to the preset liquid amount value, the function of automatically conveying the aluminum liquid is realized, the real-time liquid supplementing is realized, the aluminum liquid supply of the whole circuit is ensured, the automatic aluminum liquid conveying can be realized, and the operation efficiency is effectively improved. Since the liquid amount feedback mechanism is established, automatic supply of the aluminum liquid in the quantitative furnace 2 can be realized, that is, as long as the liquid amount of the aluminum liquid in the quantitative furnace 2 is lower than a preset value, the first pumping device 5 sucks a corresponding amount of the aluminum liquid from the melting furnace 1. Therefore, in the process, the liquid supplementing can realize high-frequency and low-flow supply, the liquid level in the quantitative furnace 2 can be maintained stable at all times, the phenomenon that the oxide layer is damaged due to overlarge fluctuation of the liquid level is prevented, the oxide layer is mixed into the aluminum liquid to influence the quality of the product, the quantitative precision is ensured, and the product percent of pass is improved.
The specific structure and installation position of the first pumping device 5 are not limited in the present disclosure, for example, an air pressure transmission pump can be used, so that the first pumping device has a large output and continuous conveying capability, and rapid medium cleaning is started, so that stable and sufficient aluminum liquid transmission can be satisfied, and uninterrupted aluminum liquid supply is ensured. The pneumatic transfer pump may be provided in the dosing furnace 2, i.e. to suck the aluminium liquid from the end of the flow path. Meanwhile, the molten aluminum in the quantitative furnace 2 should satisfy a preset purity standard, and in the embodiment of the present disclosure, the melting of the molten aluminum and the post-treatment (e.g., melting, degassing, filtering) may be performed in the melting furnace 1, in which case the furnace holding chamber 11 may include a plurality of chambers separated from each other. For example, referring to fig. 2, an aluminum liquid transfer system of an embodiment of the present disclosure may include: a furnace holding chamber 11, a process chamber 12 and a transfer chamber 13. The furnace heat insulating chamber 11 may be a melting process chamber for melting a raw material into an aluminum liquid, or may be a chamber for storing and insulating an aluminum liquid flowing from the outside, and the functions of the furnace heat insulating chamber 11 may be selectively set according to actual production conditions. The treatment chamber 12 is communicated downstream of the furnace holding chamber 11 for treating the aluminum liquid to meet the standards for supplying a given amount of the furnace 2. The transfer chamber is provided downstream of the processing chamber 12, and communicates with the processing chamber 12 and the transfer passage 4 described above, and serves as a temporary storage for supplying the molten aluminum from the melting furnace 1 to the quantitative furnace 2. Here, the flow of the molten aluminum is only from the furnace holding chamber 11 to the transfer chamber 13, and the molten aluminum is largely different from water in fluidity, so that the molten aluminum does not substantially flow back in the absence of external force. Therefore, when the first pumping device 5 of the transfer chamber 13 is operated, the pump body sucks the aluminum liquid to lower the aluminum liquid level in the transfer chamber 13, and the aluminum liquid level in the processing chamber 12 is higher than the aluminum liquid level in the transfer chamber 13, so that the aluminum liquid in the processing chamber 12 can flow into the transfer chamber 13.
According to some embodiments, the furnace holding chamber 11, the processing chamber 12 and the transfer chamber 13 may be configured as closed chambers, respectively, and only the external parts communicated with the other structures in the upstream and downstream flow paths are communicated, so as to prevent leakage of the molten aluminum during the transportation inside the melting furnace 1.
According to some embodiments, the processing chamber 12 may be sequentially provided with a degassing bin 121 and a BPF filter plate 122 (Bonded Particle Filters, all-particle bonding filter), so that the aluminum liquid flowing into the processing chamber 12 through the furnace insulation chamber 11 can be degassed and filtered, so that excessive impurities in the aluminum liquid are removed, and the quality of the output aluminum liquid is ensured.
Illustratively, the aluminum liquid in the processing chamber 12 is first fed into the degassing bin 121 for degassing, a rotary degassing machine can be arranged in the degassing bin 121, and impurities in the aluminum liquid are carried away from the aluminum liquid through inert gas bubbles which do not react with the aluminum liquid by adopting an inert gas (such as argon or nitrogen) degassing principle. For impurities which cannot be carried away by inert gas bubbles, the aluminum liquid can be filtered again through the BPF filter plate 122, so that the aluminum liquid filtered by the degassing bin 121 and the BPF filter plate 122 has qualified quality, and the production requirement is met. The aluminum liquid is purified by each treatment process in the treatment chamber 12 and then flows into the transfer chamber 13.
According to some embodiments, the transfer chamber 13 may comprise a first heating portion 131 and a first temperature monitoring portion 132 in communication with the first heating portion 131 for heating the aluminium liquid prior to transfer to the transfer channel. The aluminum liquid in the quantitative furnace 2 usually has a temperature requirement, and when the aluminum liquid is processed in the processing chamber 12 (for example, when part of impurities are removed by the rotary degasser in the degassing bin 121), a temperature drop phenomenon can occur, so that the first heating part 131 is arranged in the transferring chamber 13, and the aluminum liquid can be ensured to have a sufficient transferring temperature before being transported out of the transferring chamber 13. Meanwhile, in order to ensure that the heating process is considerable and controllable, the temperature of the aluminum liquid is monitored in real time by using the first temperature monitoring part 132, and the obtained temperature information is sent to the first heating part 131 through a signal, and the first heating part 131 can judge whether to heat the aluminum liquid according to a preset temperature value and stop heating after the temperature of the aluminum liquid meets the preset temperature value.
The specific structure of the first heating portion 131 and the first temperature monitoring portion 132 is not limited in this disclosure, and any suitable structure in the art may be used, for example, the first heating portion 131 may be in direct contact with the aluminum liquid in the transfer chamber 13, or may be configured to heat the internal environment of the transfer chamber 13 itself.
According to some embodiments, referring to fig. 1, the transfer channel 4 may comprise a chute 41 arranged between the melting furnace 1 and the dosing furnace 2 for transporting the aluminium liquid pumped out of the transfer chamber 13 into the dosing furnace 2. As shown in fig. 1, the chute 41 may have a certain inclination angle, and the inlet of the chute 41 near the melting furnace 1 is higher than the outlet near the dosing furnace 2, so that the aluminum liquid can be transported, and the aluminum liquid can flow toward the dosing furnace 2 by gravity without flowing back. To control the flow rate of the aluminum liquid, the inclination angle of the chute 41 may be adaptively designed according to the actual environment, and in some embodiments, the chute 41 may be configured with an adjustable inclination angle so as to change in real time according to the actual flow rate requirement.
Since a temperature drop may occur during the process of transferring the molten aluminum to the dosing furnace 2 through the chute 41, in order to prevent the molten aluminum from being cooled due to the excessively long transfer distance, in the embodiment of the disclosure, the transfer channel 4 may further include a second heating portion 42 disposed adjacent to the chute 41 and a second temperature monitoring portion 43 communicatively connected to the second heating portion 42, and the temperature of the molten aluminum in the chute 41 is controlled to a preset level by the second heating portion 42 and the second temperature monitoring portion 43.
In the above embodiment, the chute 41 may be integrally provided with a seal, so as to prevent the molten aluminum from overflowing the chute 41 during the transfer process, and ensure safety. Similar to the first heating portion 131 and the first temperature monitoring portion 132 described above, the specific forms of the second heating portion 42 and the second temperature monitoring portion 43 are not limited in the present disclosure. For example, on the premise that the chute 41 is integrally and hermetically arranged, the second heating portion 42 can adopt a radiation type heating means, so that the aluminum liquid in the airtight chute 41 can be effectively heated, and the specific shape of the second heating portion 42 can be set to be square plate-shaped or strip-shaped in a tubular shape close to the chute 41, so that a heating effect can be better provided. Meanwhile, the second temperature monitoring portion 43 is used to monitor the molten aluminum in the chute 41, and its function is the same as that of the first temperature monitoring portion 132 described above, and will not be described here.
Referring to fig. 4, the electrode level gauge 6 is respectively disposed at the inlet of the quantifying furnace 2 and the outlet of the chute 41, so that it is possible to monitor in real time whether an overflow phenomenon of the aluminum liquid occurs during the process of transporting the aluminum liquid from the chute 41 to the quantifying furnace 2. The electrode level gauge 6 stretches into downwards from the top of the space with the aluminum liquid, when the aluminum liquid is conveyed at an excessively high speed and the generated liquid rolls over or the aluminum liquid overflows, the electrode level gauge 6 measures the signal and feeds the signal back to the first pumping device 5, so that the conveying power is changed according to a preset standard, and the safe conveying of the aluminum liquid is ensured. Of course, in other embodiments, the electrode level gauge 6 may be replaced by other forms of sensors.
According to some embodiments, a standing chamber 22 can be arranged in the quantifying furnace 2, the fluctuation range of the liquid level of the aluminum liquid in the quantifying furnace 2 can be controlled by supplementing the aluminum liquid in a high-frequency and low-flow mode, the damage to the liquid level oxidation layer is prevented, inert gas is introduced after the aluminum liquid is firstly stood, the aluminum liquid is secondarily stood after impurities are removed, and the aluminum liquid is further purified to improve the quality of the aluminum liquid. The standing chamber 22 may be provided at one end of the dosing furnace 2 near the transfer passage 4, and when the molten aluminum is fed into the dosing furnace 2 from the transfer passage 4, the standing may be performed before the standing in the standing chamber 22, and the subsequent supply may be performed.
As described above, the quantitative furnace 2 is provided with the liquid amount monitoring device 21, where the liquid amount may be fed back by the liquid level or by the weight of the liquid, and according to some embodiments, as shown in fig. 5 and 6, the liquid amount monitoring device 21 may include a liquid level sensor 211, in which case the preset value of the liquid amount described above is the liquid level in the quantitative furnace 2, and the liquid level sensor 211 may be provided inside the quantitative furnace 2; the liquid amount monitoring device 21 may further include a load cell 212, in which case the preset value of the liquid amount is the weight of the aluminum liquid, and the load cell 212 may be disposed at the bottom of the dosing furnace 2.
Of course, in the case that the quantitative furnace 2 is provided with both the liquid level sensor 211 and the weighing sensor 212, the liquid level sensor 211 and the weighing sensor 212 can simultaneously feed back signals to the first pumping device 5, so that double-loop safety interlocking is realized, quantitative dynamic of aluminum liquid is accurately fed back, the first pumping device 5 is automatically regulated to convey the aluminum liquid into the quantitative furnace 2, and the liquid level is controlled in real time to prevent overflow. For example, the liquid level sensor 211 and the load cell 212 may respectively signal the respective monitored information to the first pumping device 5, so that the first pumping device 5 can determine whether the amount of aluminum in the quantitative furnace 2 meets a preset aluminum amount criterion according to the obtained feedback information to turn on, turn off or operate at a certain conveying power. If the liquid level sensor 211 measures that the liquid level in the quantitative furnace 2 is lower than the preset liquid level value at this time, or the weighing sensor 212 measures that the weight of the aluminum liquid in the quantitative furnace 2 is lower than the preset weight, the first pumping device 5 can be started after receiving the signal as long as any condition or both conditions are met; if only any one condition is met at this time, the first pumping device 5 can operate with a certain transmission power according to a preset standard; if either condition is not met, the first pumping means 5 may remain closed.
According to a second aspect of the embodiments of the present disclosure, as shown in fig. 3 and 6, there is also provided a die casting line including the die casting machine 3 and the above-described aluminum liquid transporting system that supplies aluminum liquid for die casting to the die casting machine, and performs a die casting process of an aluminum material by the die casting machine. The die casting line comprises the aluminum liquid transmission system in any one of the above embodiments, so that the die casting line has the beneficial effects of any one of the above embodiments, and will not be described herein.
In the disclosed embodiment, the die casting machine 3 may include a thickness monitoring device 31 and a second pumping device 32. The thickness monitoring device 31 is disposed outside the die casting machine 3, and is used for measuring the thickness of the cake in the die casting machine 3, and a measuring device with common specifications such as a double magnetic ruler can be used. The second pumping device 32 may be disposed at a connection portion between the quantitative furnace 2 and the die casting machine 3, and is in communication connection with the thickness monitoring device 31, and when the current cake thickness obtained by the thickness monitoring device 31 is smaller than the preset cake thickness (i.e. the cake thickness required for die casting in the whole system), the second pumping device 32 is fed back with a signal, so that the second pumping device 32 pumps the aluminum liquid meeting the deviation amount in the quantitative furnace 2 into the die casting machine 3. In the process of compensating the quantitative deviation, if the liquid amount in the quantitative furnace 2 is lower than the preset liquid amount value, the first pumping device 5 is started (namely, the thickness monitoring device 31 is indirectly connected with the first pumping device) and the aluminum liquid is compensated for the quantitative furnace 2 according to the high-frequency and low-flow feeding mode until the thickness of a charge cake in the die casting machine 3 and the liquid amount in the quantitative furnace 2 meet the process requirements, and the pumping is stopped.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure. This disclosure is intended to cover any adaptations, uses, or adaptations of the disclosure following the general principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
