[0024] A heat-insulating quantitative extraction device for liquid metal, such as Figures 1 to 4 As shown, the device includes a lifting rod 1, a connecting claw 2 at its lower end, and an extraction cylinder 3 below the connecting claw. The upper end of the extraction cylinder is open. A liquid level sensor is installed on the connecting claw or inside the extraction cylinder. An insulation component is installed on the outer wall of the extraction cylinder. The liquid level sensor senses the liquid level in the cylinder in real time and accurately calculates the liquid volume using a PLC. When the set extraction liquid volume is reached, the PLC controls a sealing head to seal the inlet at the bottom of the extraction cylinder, ensuring precise and controllable liquid extraction each time.

[0026] A corresponding overfeed port is provided with a plug 7, and the lower part of the plug is provided with a conical structure matched with the overfeed port, and when the plug is attached to the overfeed port, the top surface 8 of the plug is flush with the upper surface of the bottom plate of the extraction cylinder. The plug is driven by a second lifting mechanism 9 to adjust the height position, thereby changing the matching relationship between the plug and the overfeed port. In the present invention, the lifting mechanism is realized by screw type or electric push (pull) type to realize the pressing and extraction action. As an example, the first lifting mechanism includes an electric push rod or a hydraulic push rod. The second lifting mechanism includes an electric push rod or a hydraulic push rod.

[0027] It should be noted that the first lifting mechanism and the second lifting mechanism are electrically connected with the PLC, and respectively receive the PLC command to perform the elongation or contraction action. The PLC control mode improves the automation degree and production efficiency. As an example, the heat preservation assembly includes a high-frequency heating induction coil or an infrared heat sensor, which can realize real-time heating and heat preservation for the metal liquid and the extraction barrel, and ensure that the temperature of the metal liquid remains within the required range during the extraction and transfer process.

In an alternative embodiment, the connecting claw includes a base frame 10, and a plurality of claw bodies 11 are arranged at the lower part of the base frame, and each claw body is welded and fixed to the outer wall of the extraction cylinder. The lifting rod is arranged at the center of the base frame, and the second lifting mechanism and the plug are eccentrically arranged and are located away from the lifting rod to avoid interference between the structural members.

[0029] The present invention has reasonable structure design and good operation convenience.
