Fifthly, the charging hole and the slag removing hole are separately arranged, so that the manufacturing cost and the use and maintenance cost of the furnace body are high. A split quantitative furnace. The top-down funnel-shaped feeding device is cancelled, a barrel-shaped pressurizing cavity is arranged in the furnace body to be used as an independent sealing cavity, but the following technical problems are solved: firstly, because the hot water outlet sets up at the furnace body front end, receives the restriction that the furnace body appearance was interfered, the distance of hot water outlet to die casting machine material jar can't shorten, and aluminium liquid easily forms the cinder in transportation process. Secondly, the pressurizing cavity is generally not provided with a heating rod, so that the risk of aluminum condensation exists, and once a fault occurs, the whole cavity needs to be replaced, so that the maintenance cost is very high. Thirdly, the split type quantitative barrel is limited by the installation size, and the maximum quantitative amount is not easy to expand. Fourthly, the charging hole and the slag removing hole are separately arranged, and the manufacturing cost and the use and maintenance cost of the furnace body are high. The above problems need to be solved in an urgent need by combining the disadvantages of the integrated and split type quantitative furnaces.

The feeding mode is as follows: the second cylinder driving device 402 is driven, the feeding cover 401 is opened, aluminum liquid is injected into the feeding slag removal port 104, when the liquid level rises to contact the first electrode probe 106, the aluminum liquid triggers an electrode signal as a conductive medium, so that the alarm device sends out alarm buzzing sound and an indicator lamp is turned on, feeding is stopped, the feeding cover 401 is driven to be closed, and the probe plays a role in protecting the liquid level from overflowing the feeding port.

In order to realize the function of quantitative charging at the same time, the control system is provided with a non-charging state and a charging state; conventional dosing mode of double gas pressure with no charge: in the non-charging state, the conventional quantitative mode is selected, and the first algorithm program control is started. The first heating rod 103 and the first thermocouple 105 are arranged in the heat preservation chamber 102, and when the real-time temperature of the heat preservation chamber 102 fed back by the first thermocouple 105 exceeds a set temperature range, the first heating rod 103 works to supplement heat or stops working. When the temperature of the furnace body 100 reaches the set temperature, the first thermocouple 105 feeds back the real-time temperature to the PLC system, quantitative instructions are started when quantitative conditions are met, the second pressure adding and releasing port 107 pressurizes the heat preservation chamber 102, aluminum liquid rises through the first liquid lifting pipe 110, the check mechanism 202 is in an open state at the moment, the aluminum liquid enters the quantitative device 200, the quantitative device 200 is installed on the upper end face of the shell of the furnace body 100, and the bottom of the quantitative device is provided with a support 109 for hanging and extending. The method requires one: the check mechanism 202 in embodiment 1 comprises a first cylinder driving device 202b for driving a top rod 202c so as to function as a sealing check valve with a V-shaped bushing 202d, wherein a first pressure adding and releasing port 202e is formed on a cylinder sealing support 202a, and a first lift pipe 110 is arranged below the cylinder sealing support; the second requirement is that: the check mechanism 202 in embodiment 2 includes a fixed post 202c to prevent the round ball 202f (with a density higher than that of the molten aluminum) from being pushed open by the molten aluminum and unable to return, the round ball 202f and the V-shaped bushing 202d perform a one-way check sealing function when the first pressure relief opening 202e relieves pressure, and the first lift tube 110 is disposed below the round ball 202f and the V-shaped bushing 202 d. The quantitative device 200 is provided with a second heating rod 204, when the real-time temperature fed back by the second thermocouple 205 exceeds the set temperature range, the second heating rod 204 works to supplement heat or stops working, the aluminum liquid rises to the set quantitative liquid level and contacts the second electrode probe 203b, and the aluminum liquid is used as a conductive medium trigger signal. At the moment, the PLC controls to execute triple linkage action, and the second electrode probe driving device 203c (driven by a cylinder or a motor) is linked to enable the second electrode probe 203b to retreat from and contact with the aluminum liquid; the second pressure adding and releasing port 107 is controlled in a linkage mode to execute pressure releasing action; the coordinated control cylinder ram/ball check 202 is immediately closing. At this time, the aluminum liquid in the first lift pipe 110 will not fall back into the heat preservation chamber under the action of air pressure, and then the first pressure adding and releasing port 202e applies inert gas, and the aluminum liquid flows through the second lift pipe 203a, the material conveying nozzle 203d and the diversion trench 203e and flows into the feed cylinder of the die casting machine. The pressure detection mechanism is matched with the quantifying device 200, the control cabinet calculates and analyzes the pressure change in the furnace cavity, the pressurizing time is controlled, and the molten aluminum is accurately and quantitatively conveyed to the feeding hole of the die casting machine; and through quick-witted limit switch board automatic control for give hot water parameter invariable, can realize synchronous with the die casting machine.

The aluminum liquid reaches the measured liquid level in the barrel to trigger the second electrode probe to capture a liquid level signal in each quantitative process, so that the initial positions of each quantification are consistent, and the stability of a quantitative algorithm is ensured.

Further, the single-air-pressure quantitative mode while feeding is as follows: the mode is to satisfy the quantitative operation of the quantitative furnace while charging without stopping. When the PLC control system calculates that the aluminum liquid in the heat preservation chamber 102 is insufficient, the alarm indicator lamp 108 lights and buzzes, and an operator can switch to a quantitative mode while feeding, and start the second algorithm program control (in the prior art, no further description is given). The quantitative device 200 enters an independent working state, and the aluminum liquid capacity of the quantitative device 200 is set to meet the requirement of continuous quantitative operation for a plurality of quantitative periods within the charging time. In this mode, the second pressure-relief port 107 is in a pressure-relief state, and the cylinder ram/ball check mechanism 202 is always in a closed state. In the single quantitative mode, by applying pressure with inert gas as a medium to the first pressure adding and releasing port 202e, aluminum liquid enters the second lift pipe 203a under the action of pressure difference and contacts the second electrode probe 203b, the second electrode probe 203b retreats from the liquid level, the aluminum liquid flows to the diversion trench 203e and enters the die casting machine, when the mode is started, the height of the aluminum liquid in the quantitative device 200 is at the quantitative liquid level height, namely the maximum quantitative liquid level, the initial liquid level height is consistent, and a certain height of the aluminum liquid can be consumed in each quantitative period. The pressure detection mechanism is matched with the quantifying device 200, the control cabinet calculates and analyzes the pressure change in the furnace cavity, the pressurizing time is controlled, and the molten aluminum is accurately and quantitatively conveyed to the feeding hole of the die casting machine; and through quick-witted limit switch board automatic control for give hot water parameter invariable, can realize synchronous with the die casting machine. After the feeding is completed, the feeding cover 401 is closed, and the normal quantitative mode is switched back according to the requirement.
