Description

Technical Field

[0001] The utility model relates to the technical field of metal melting furnace equipment, in particular to a high-efficiency heat storage type non-ferrous metal melting furnace. Background Art

[0002] Non-ferrous metals play a vital role in the national economy, defense industry, science and technology, and modern life. They possess many excellent properties, such as high strength, excellent electrical and thermal conductivity, corrosion resistance, wear resistance, high melting points, and unique magnetic, optical, and electrical properties. These characteristics have led to their widespread application in the electrical, metallurgical, mechanical, chemical, and construction industries, as well as in defense and science and technology. Specifically, non-ferrous metals include a variety of metallic elements, such as aluminum, magnesium, copper, lead, zinc, tin, nickel, cobalt, tungsten, molybdenum, vanadium, titanium, rare earth elements, zirconium, hafnium, gallium, niobium, tantalum, and germanium. The distribution and abundance of these metallic elements in nature vary, with some being relatively abundant and others relatively scarce. Furthermore, alloys of non-ferrous metals are widely used due to their unique properties. For example, aluminum alloys, due to their light weight, high strength, and excellent corrosion resistance, are widely used in aerospace, transportation, and construction. Copper alloys, due to their excellent electrical and thermal conductivity and corrosion resistance, are widely used in electrical, electronic, and refrigeration applications.

[0003] Non-ferrous metals need to be smelted when they are used. After searching, the Chinese patent application number is: CN202111150840.2, which relates to a metal melting furnace, comprising a movable seat with movable wheels at the four corners of the bottom surface and a support frame installed on the top surface of the movable seat. The top end of the inner cavity of the support frame is rotatably connected to a vacuum shell, and the outer end surface of the bottom end of the support frame is hinged with a first telescopic member, which connects to and drives the vacuum shell. A crucible is provided in the vacuum shell. The invention uses the U-shaped movable seat and the support frame to provide rotational support for the vacuum shell, which is more convenient for movement and adjustment, and the hinge axis and the flip axis are used to form a double-point support for the vacuum shell, and then the flip axis cooperates with the first telescopic member, and the first telescopic member drives the flip axis to drive the vacuum shell to rotate around the hinge axis, which is more convenient for discharging molten metal and can perform real-time position adjustment and positioning of the vacuum shell. Compared with traditional single-axis rotation, it has higher stability and is more convenient to operate.

[0004] The above technical solution still has defects, that is, the energy utilization efficiency is low. During the heating process, a large amount of heat is dissipated through the flue and other channels and cannot be effectively reused, resulting in energy waste. Therefore, we need to propose a high-efficiency heat storage non-ferrous metal melting furnace. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3 , the utility model provides a technical solution:

[0024] A high-efficiency heat storage type nonferrous metal melting furnace, comprising:

[0025] Main structure; The main structure includes an outer shell 1, an inner liner 2 and a combustion chamber 3. The inner liner 2 is located inside the outer shell 1, and the combustion chamber 3 is located at the bottom of the outer shell 1. A fuel supply pipeline and an ignition device are provided in the combustion chamber 3. An air intake pipe 4 connected to the outer shell 1 is provided on one side of the outer wall of the upper end of the outer shell 1, and an exhaust pipe 5 connected to the outer shell 1 is provided on one side of the outer wall of the lower end of the outer shell 1;

[0026] It also includes a heat storage mechanism, which includes a cover 11 arranged inside the outer shell 1, a ceramic heat storage body 12 provided on the cover 11, an air inlet 14 corresponding to the air inlet pipe 4 is opened on the outer wall of one side of the lower end of the cover 11, an exhaust gas outlet 15 corresponding to the exhaust pipe 5 is opened on the outer wall of one side of the upper end of the cover 11, and a partition 13 is provided on the cover 11 to separate the air inlet and the air outlet. The upper end of the cover 11 is connected to the bottom of the support ring 9, and the lower end of the cover 11 is connected to the inner bottom of the outer shell 1. One-way valves are installed on both the air inlet pipe 4 and the exhaust pipe 5. The upper end of the cover 11 is connected to the bottom of the support ring 9, and the lower end of the cover 11 is connected to the inner bottom of the outer shell 1. One-way valves are installed on both the air inlet pipe 4 and the exhaust pipe 5.

[0027] The utility model is provided with a main structure including an outer shell 1, an inner liner 2 and a combustion chamber 3. An air inlet pipe 4 and an exhaust pipe 5 are provided on the outer shell 1, and a heat storage mechanism including a cover shell 11 is further provided. The cover shell 11 is located inside the outer shell 1 and a ceramic heat storage body 12 is provided on the cover shell 11. An inlet 14 and an outlet 15 are provided on the cover shell 11 for air to enter and leave the combustion chamber 3. In actual use, the inner liner 2 is inserted into the outer shell 1, and the non-ferrous metal to be smelted is placed in the inner liner 2. Fuel is supplied to the combustion chamber 3 through a pipeline and ignited for heating and smelting. At the same time, air is pumped into the outer shell 1 through the air inlet pipe 4. After entering the outer shell 1, the air passes through the ceramic heat storage body 12, and then enters the combustion chamber 3 through the inlet 14 at the bottom of the cover shell 11 and is mixed with the fuel for combustion. The smoke after combustion passes through the outlet 15 above the cover shell 11 and enters the exhaust pipe 5 after passing through the ceramic heat storage body 12.

[0028] During this process, the ceramic heat storage body 12 can store the heat carried by the flue gas. When the cold air enters the shell 1 and passes through the ceramic heat storage body 12, it can be preheated, thereby increasing the temperature of the air entering the furnace body, realizing heat recovery and improving the smelting efficiency.

[0029] During this process, external cold air enters the outer shell 1 and sinks, and enters the inlet 14 after passing through the ceramic heating body. The high-temperature flue gas generated by combustion rises and passes through the outlet 15 of the cover 11, and then passes downward through the ceramic heat storage body 12 for heat recovery to become cold flue gas, and sinks and is discharged through the exhaust pipe 5. This design is more in line with the thermal circulation, making the design of this device more scientific and effective.

[0030] In general, the device has a simple structure and is easy to use. Through the cooperation of the main structure and the heat storage mechanism, it can utilize energy more efficiently, avoid heat loss and waste of heat energy, and has high practical value.
