Description

Technical Field

[0001] The utility model relates to a dosing furnace chute, in particular to the structure of the dosing furnace chute. Background Art

[0002] Aluminum alloy has the characteristics of low density, good mechanical properties, good processing performance, excellent electrical conductivity, thermal conductivity and corrosion resistance. Aluminum alloy die-casting products are mainly used in electronics, automobiles, motors, home appliances and some communications industries. Some high-performance, high-precision, high-toughness high-quality aluminum alloy products are also used in large aircraft, ships and other industries with relatively high product quality requirements.

[0003] Traditional die-casting machines typically use a ladle pouring method before the die-casting process. This involves using an open-top holding furnace to keep the molten aluminum warm. A robotic ladle is then used to draw molten aluminum from the furnace's draw port and then feed it to the die-casting machine's feed tank. The molten aluminum temperature can be controlled at 620°C to 630°C. However, this method results in poor aluminum purity, low precision, high operational risks, and low production efficiency. As the quality requirements for aluminum alloy die-casting products continue to rise, so too do the requirements for equipment used to melt and store molten aluminum.

[0004] Existing methods typically utilize a dosing furnace for feeding. Dosing furnaces offer excellent insulation during normal operation, thus reducing energy consumption. Molten aluminum is fed into the enclosed furnace via a feeding hopper. Under pressure, the molten aluminum rises into a riser tube and then flows from the furnace into the filling chamber of the die-casting machine via a tubular chute. The dosing furnace is controlled by an electronic control system, capable of providing a quantitative supply of molten aluminum. This system simultaneously replenishes the furnace with molten aluminum, monitors the furnace's level and pressure, and offers low energy consumption. However, due to the long distance between the chute and the dosing furnace and its poor insulation, the molten aluminum easily solidifies at the end of the chute, leading to chute blockage and interruption of feeding, impacting normal production.

[0005] The utility model aims to solve the problem that the existing quantitative furnace chute has poor thermal insulation effect and the aluminum liquid is easy to solidify at the end of the chute, resulting in chute blockage. Utility Model Content

[0006] In order to solve the above problems, the utility model provides a quantitative furnace chute, including a guide pipe 1, which is a straight pipe. A connector 2 for connecting to a rising liquid pipe 51 of a quantitative furnace 5 is provided at one end, and a discharge head 3 is provided at the other end. An interlayer 11 is provided inside the guide pipe 1. The discharge head 3 is a curved pipe, one end of which is connected to the guide pipe 1, and the other end forms a discharge port 31. A heating element 12 is provided in the interlayer 11.

[0007] The present invention provides an interlayer 11 within the flow guide tube 1, and a heating element 12 within the interlayer 11. When the temperature of the molten aluminum in the flow guide tube 1 is low, the heating element 12 heats the molten aluminum in the flow guide tube 1, maintaining the molten aluminum at an appropriate temperature and preventing it from solidifying. This solves the problem of poor thermal insulation in the chute of existing quantitative furnaces, where molten aluminum easily solidifies at the end of the chute, leading to chute blockage.

[0008] Preferably, a temperature sensor 32 is further included and is disposed inside the discharge head 3. The temperature sensor 32 is disposed inside the discharge port 31 of the discharge head 3 to detect the temperature of the molten aluminum in real time. When the temperature of the molten aluminum is low, the heating element 12 is controlled to heat the molten aluminum in the flow guide tube 1 to prevent the molten aluminum from solidifying.

[0009] Preferably, a heat-insulating layer is provided on the outer wall of the flow guide tube 1. Providing a heat-insulating layer on the outer wall can keep the aluminum liquid in the flow guide tube 1 warm and reduce the heat dissipation speed of the aluminum liquid.

[0010] Preferably, the outlet end of the discharge head 3 is in a constricted shape. Setting the outlet end of the discharge head 3 in a constricted shape can facilitate adding aluminum liquid into the material cylinder of the die casting machine.

[0011] Preferably, the discharge head 3 is connected to the guide tube 1 by a thread. Setting the discharge head 3 and the guide tube 1 by a threaded connection can facilitate the disassembly and assembly of the discharge head 3 and the cleaning of the rotating shaft inside the discharge head 3 and the guide tube 1.

[0012] Preferably, the controller 4 is further included, and the controller 4 is connected to the temperature sensor 32 and the heating element 12 respectively. The controller 4 can receive the temperature information of the aluminum liquid detected by the temperature sensor 32, and when the temperature of the aluminum liquid is low, control the heating element 12 to heat the aluminum liquid in the flow guide tube 1. When the temperature of the aluminum liquid is high, control the heating element 12 to stop heating the aluminum liquid in the flow guide tube 1, so that the temperature of the aluminum liquid in the flow guide tube 1 is at an appropriate temperature to prevent the aluminum liquid from solidifying.

[0013] Preferably, the connecting member 2 is a connecting flange, which can tightly and fixedly connect the flow guide pipe 1 to the liquid riser 51 of the quantitative furnace 5, making it easy to disassemble and assemble.

[0014] Preferably, the heating element 12 is an electric heating wire, which can quickly heat the aluminum liquid in the flow guide tube 1. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, the quantitative furnace chute includes a guide pipe 1 and a controller 4. The guide pipe 1 is a straight pipe, one end of which is provided with a connector 2 for connecting to the rising pipe 51 of the quantitative furnace 5, and the other end is provided with a discharge head 3. The inner part of the guide pipe 1 is provided with an interlayer 11. Figure 3 .

[0023] The outer wall of the flow guide tube 1 is provided with a heat-insulating layer (not shown in the figure). The heat-insulating layer can keep the aluminum liquid in the flow guide tube 1 warm and reduce the heat dissipation rate of the aluminum liquid.

[0024] The connecting piece 2 is a connecting flange. The connecting flange can make the guide pipe 1 and the liquid riser 51 of the quantitative furnace 5 tightly fixedly connected, convenient for disassembly and assembly, and easy for replacement and cleaning of internal impurities.

[0025] The heating element 12 is an electric heating wire, which can quickly heat the aluminum liquid in the guide tube 1.

[0026] A heating element 12 is provided in the interlayer 11. When the temperature of the aluminum liquid in the flow guide tube 1 is low, the heating element 12 heats the aluminum liquid in the flow guide tube 1 to keep the aluminum liquid at a suitable temperature to prevent the aluminum liquid from solidifying.

[0027] The discharge head 3 is a curved pipe, one end of which is detachably connected to the guide tube 1, and the other end forms a discharge port 31. A temperature sensor 32 is provided inside the discharge head 3, which can detect the temperature of the aluminum liquid in real time. When the temperature of the aluminum liquid is low, the heating element 12 is controlled to heat the aluminum liquid in the guide tube 1 in time.

[0028] The outlet end of the discharge head 3 is in a constricted shape. Setting the outlet end of the discharge head 3 in a constricted shape can facilitate adding aluminum liquid into the material cylinder of the die casting machine.

[0029] The discharge head 3 is connected to the guide tube 1 by a thread. The discharge head 3 and the guide tube 1 are connected by a thread, which can facilitate the disassembly and assembly of the discharge head 3 and the cleaning of the rotating shaft inside the discharge head 3 and the guide tube 1.

[0030] The controller 4 is connected to the temperature sensor 32 and the heating element 12. The controller 4 receives the temperature information of the molten aluminum detected by the temperature sensor 32. When the temperature of the molten aluminum is low, the controller 4 controls the heating element 12 to heat the molten aluminum in the flow conduit 1. When the temperature of the molten aluminum is high, the controller 4 controls the heating element 12 to stop heating the molten aluminum in the flow conduit 1. This ensures that the temperature of the molten aluminum in the flow conduit 1 is at an appropriate level to prevent the molten aluminum from solidifying.

[0031] The utility model provides an insulation layer on the outer wall of the guide tube 1 to insulate the aluminum liquid in the guide tube 1 and reduce the heat dissipation rate of the aluminum liquid. An interlayer 11 is provided inside the guide tube 1, and a heating element 12 is provided inside the interlayer 11. When the temperature of the aluminum liquid in the guide tube 1 is low, the heating element 12 heats the aluminum liquid in the guide tube 1 to keep the aluminum liquid at an appropriate temperature and prevent the aluminum liquid from solidifying.

[0032] A temperature sensor 32 is installed inside the discharge head 3 to monitor the temperature of the molten aluminum in real time. When the temperature is low, the heater 12 is controlled to heat the molten aluminum in the flow tube 1 to prevent solidification. The discharge head 3 and flow tube 1 are connected via threads, which facilitates assembly and disassembly of the discharge head 3 and cleaning of the rotating shafts inside the discharge head 3 and flow tube 1. The flow tube 1 is fixedly connected to the riser pipe 51 of the dosing furnace 5 via a connecting flange, ensuring a tight and secure connection between the two, making assembly and disassembly easier.

[0033] It should be noted that the above-mentioned embodiments illustrate rather than limit the invention and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims.
