Obviously, the described embodiment is only a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] refer to Figure 1 As shown, a control system for a liquid level control method of an aluminum casting furnace includes a control device and a discharge metering mechanism, a feed metering mechanism, a discharge mechanism and a feed mechanism connected to the control device, the discharge mechanism is arranged at the discharge port of the aluminum casting furnace, the discharge metering mechanism is arranged on the discharge mechanism and connected to the discharge mechanism, and the feed mechanism is arranged at the feed port of the aluminum casting furnace and is connected to the feed metering mechanism.

[0025] In order to ensure the stability of the feeding quality, the commonly used cast aluminum furnaces at present usually use a baffle to divide the cast aluminum furnace into a feeding bin and a discharging bin, wherein the bottoms of the feeding bin and the discharging bin are connected, or other means with the same principle are used to divide the cast aluminum furnace into two parts, namely, a feeding bin and a discharging bin. In this way, the materials fed into the feeding bin are mostly solid, which are heated and melted in the feeding bin, and flow into the discharging bin from the feeding bin under pressure. More importantly, the feeding bin also utilizes the difference in density of objects, that is, the density of the fed materials is greater than the density of impurities, and removes impurities from the fed materials, so that the impurities float to the top layer of the feeding bin for easy cleaning. In addition, the feeding quality described in this embodiment includes a series of parameters such as the purity, fluidity, uniformity of the melt and the temperature of the melt, which seriously affect the quality of the die-cast products. After being processed by the technical solution provided in this embodiment, the stability of the feeding quality is ensured, thereby ensuring the stability of the product quality.

[0026] In this embodiment, a buffer furnace is also provided at the discharge port of the aluminum casting furnace, and a switch is provided between the buffer furnace and the aluminum casting furnace. When the feeding bin stops feeding, but the feeding work of the feeding bin is not stopped in time, and the liquid level of the feeding bin has reached the highest point, the buffer furnace can reduce the storage pressure of the feeding bin and the feeding bin, thereby achieving stable control of the molten material level.

[0027] Specifically, the switch in this embodiment is connected to the control device and the discharging mechanism respectively.

[0028] Furthermore, the present embodiment also includes a metering device arranged in the furnace, and the metering device is respectively connected to the control device, the discharging mechanism, the discharging metering mechanism and the switch. Specifically, the metering device is arranged in the flow channel between the feed bin and the feeding bin, and is used to control and obtain the liquid flow and flow velocity between the feeding bin and the feed bin, so as to ensure the stability of the liquid level in the feed bin.

[0029] A control method for a liquid level control system of an aluminum casting furnace provided in this embodiment includes the following steps: Figure 2 As shown,

[0030] The feeding system of the aluminum casting system is turned on, and the discharging metering mechanism determines whether the discharging mechanism is turned on;

[0031] If yes, the opening information of the discharging mechanism is sent to the control device;

[0032] The control device processes the opening information and opens the feeding mechanism; at the same time,

[0033] The material discharging metering mechanism obtains the material discharging information and transmits it to the control device, wherein the material discharging information at least includes information such as the material discharging flow rate, the material discharging flow rate, and the material discharging amount;

[0034] After the control device performs data analysis and processing on the discharge information, it sends control information to the feed metering mechanism;

[0035] The feed metering mechanism adjusts the feed data of the feed metering device according to the control information obtained.

[0036] To sum up, the technical solution provided in this embodiment performs real-time detection of the material dynamics of the feed bin and the discharge bin through the discharge metering mechanism and the feed metering mechanism, and sends the detection data to the control device to uniformly adjust the speed, flow rate and other parameters of the feed and discharge, thereby realizing the control of the liquid level stability of the cast aluminum furnace, providing a guarantee for the mold to provide uniform and stable molten liquid, and also providing a guarantee for the mechanized, streamlined, standardized and automated metal die-casting process, ultimately achieving the purpose of improving product quality and improving production efficiency; in addition, when the storage volume of the feed bin and the feeding bin exceeds the limit, the buffer bin can also be used to reduce the storage pressure of the feed bin and the feeding bin, thereby achieving the quality stability of the feeding molten liquid.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
