Description

Technical Field

[0001] This utility model specifically relates to the technical field of aluminum profile processing, and specifically to a melting furnace for aluminum material processing. Background Technology

[0002] Aluminum profiles are aluminum products with specific cross-sectional shapes produced from aluminum alloys through processes such as hot melting, extrusion, and rolling. Therefore, a smelting furnace is usually required during processing. A reverberatory furnace is one type of smelting furnace. It is a chamber-type flame furnace that mainly relies on the high-temperature flame and furnace gas generated by fuel combustion to transfer heat through reflection from the furnace top and furnace walls, thereby achieving the heating, melting, and refining of materials.

[0003] Currently used reverberatory melting furnaces typically have a simple structure. To ensure more uniform melting of the raw materials inside, manual stirring rods are usually required during the processing stage, which are inserted into the furnace through the feed inlet. This poses significant safety risks. Furthermore, the high temperature and reduced physical strength can affect the continuity and quality of manual stirring. In addition, the efficiency of manual stirring decreases significantly as the furnace size increases. Therefore, these furnaces have drawbacks in their use. Utility Model Content

[0004] The purpose of this utility model is to provide a smelting furnace for aluminum processing, in order to solve the problems mentioned in the background art. Currently used reverberatory smelting furnaces usually require manual stirring rods to be inserted into the furnace from the feed inlet during the processing stage, which poses a significant safety hazard. Furthermore, high temperatures and reduced physical strength affect the continuity and quality of manual stirring. In addition, the efficiency of manual stirring decreases significantly as the furnace size increases. Therefore, there are drawbacks in its use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A smelting furnace for aluminum processing includes a furnace body mounted on top of a base, with a reflective heat insulation layer on the inner wall of the furnace body. A feed window is located at the front end of the furnace body, and a protective door is installed at the front end of the furnace body, with the protective door rotatably connected to the furnace body. A stirring rod is mounted on the protective door, with its top end rotatably connected to a movable frame, and its end also fitted with a stirring rod. A geared motor is mounted on the movable frame, and its drive shaft is connected to the stirring rod. Two first hydraulic rods are symmetrically distributed at both ends of the top of the base, with their extensions connected to two connecting rods, which in turn are connected to both ends of the movable frame. Two second hydraulic rods are symmetrically distributed at the front end of the base, with their extensions rotatably connected to both sides of the protective door.

[0007] As a further embodiment of this utility model: the smelting furnace body is provided with an exhaust port and a feed window on one side, and both the exhaust port and the feed window penetrate the reflective heat insulation layer.

[0008] As a further embodiment of this utility model: a guide groove is provided on one side of the bottom of the reflective heat insulation layer, and the guide groove is connected to the discharge window, while the discharge window is opened on the lower part of one side of the reflective heat insulation layer; the discharge window is connected to the flow channel, and the flow channel is located on the lower part of one side of the smelting furnace body.

[0009] As a further embodiment of this utility model: a pad roller is provided on the front side of the feed window, and the pad roller is installed at the front end of the smelting furnace body, while the width of the smelting furnace body is smaller than the inner width of the feed window.

[0010] As a further embodiment of this utility model: the connection between the connecting rod and the first hydraulic rod is a rotatable connection, and the first hydraulic rod, connecting rod, movable frame, stirring rod and stirring head form a sliding structure; the connection between the stirring rod and the protective door is a movable connection.

[0011] As a further embodiment of this utility model: the connection between the second hydraulic rod and the protective door is a rotatable connection, and the second hydraulic rod, the protective door, and the stirring rod form a rotatable structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model includes a stirring rod and a stirring head, both made of 310S heat-resistant steel and coated with a special coating. The ceramic material withstands the high temperature inside the furnace during processing and can directly contact the molten aluminum for continuous stirring. The stirring rod and stirring head are driven by a geared motor to rotate slowly and continuously stir the molten aluminum. The position of the stirring rod and stirring head can be adjusted by the first hydraulic rod to improve the stirring effect and facilitate the opening of the protective door.

[0014] 2. This utility model is equipped with a pad roller, which is located in front of the lower edge of the feed window. Since the waste residue inside the aluminum melt will float on the top of the aluminum melt during the melting stage, it is necessary to use tools to manually scrape off the waste residue on the surface of the aluminum melt. The pad roller can support the long handle of the tool and reduce the resistance when the tool moves back and forth, thereby improving work efficiency.

[0015] 3. This utility model is provided with a guide groove and a discharge window. The side of the guide groove is chamfered, which can effectively guide the aluminum liquid to the discharge window during discharge, thereby improving the discharge efficiency. At the same time, the discharge window with the grid structure can block impurities in the aluminum liquid. Attached Figure Description
