Description

Technical Field

[0001] The invention relates to the technical field of recovery smelting furnaces, and in particular to an electric heating type horizontal rotary furnace for recycling alloy waste metal. Background Art

[0002] A metal recycling rotary furnace is a type of furnace used to heat materials in industries such as construction and metallurgy. It typically utilizes internal heating, typically using gas, oil, coal, or coal gasification. Air or oxygen-enriched air must also be introduced, requiring the heated material to possess a certain level of oxidation resistance and a low level of fuel pollution. If the heated material is easily oxidized, such as metal, other heating methods, such as electric heating, are necessary. Currently, internally heated metal recycling rotary furnaces primarily utilize gas, oil, coal, or coal gasification as heat sources. These metal recycling rotary furnaces are limited in their use when heating easily oxidizable materials and require a reducing atmosphere within the furnace. This led to the development of electrically heated metal recycling rotary furnaces. However, existing metal recycling rotary furnaces experience slow flow and uneven heating of the heated metal material within the furnace when melting scrap metal. This can increase the melting and heating time and can easily lead to excessive furnace temperatures, impacting normal operation. Summary of the Invention

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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 any creative efforts shall fall within the scope of protection of the present invention.

[0024] See also Figure 1 - Figure 5 As shown, the present invention is an electric heating type alloy scrap metal recycling horizontal rotary furnace, comprising an outer furnace body 1 and an inner furnace body 3 rotatably arranged in the outer furnace body 1, wherein the two ends of the outer furnace body 1 are symmetrically hingedly connected with a sealing door 2, the inner side of the sealing door 2 is provided with a pressing plate 4, and one side of the pressing plate 4 is rotatably provided with a sealing plate 5. When the scrap metal is smelted, the sealing door 2 is used to seal with the outer furnace body 1 and also to insulate the inner furnace body 3. The sealing plate 5 rotatably arranged in the middle is used to seal the inner furnace body 3 to prevent the scrap metal from leaking during the melting process. In addition, a pressure regulating tube 20 is provided on a sealing door 2 to adjust the pressure in the inner furnace body 3. Specifically, an electric heating rack 6 is provided on the inner side of the inner furnace body 3. The electric heating rack 6 is used to heat and melt the scrap metal. The use of electric heating can avoid air pollution to the workshop caused by combustion of gas or fuel, affecting In order to improve the health of the operating employees, an equipment room 10 is set below the outer furnace body 1, and a power supply block 16 is set in the equipment room 10. Then, a power supply chute 160 is opened above the power supply block 16, and then, power supply balls 162 are symmetrically arranged in the power supply chute 160. In the process of the inner furnace body 3 rotating to the left, the power rail 33 arranged on the outside of the inner furnace body 3 is always in contact with the power supply ball 162, which can achieve a good power supply effect and ensure that the inner furnace body 3 will not be powered off during the rotation process. At the same time, positioning balls 161 are symmetrically arranged in the power supply chute 160 to ensure the stability of the contact of the power rail 33 during the rotation process. An insulated thermometer 11 is set on the outside of the outer furnace body 1 to detect the temperature between the inner furnace body 3 and the outer furnace body 1 to avoid the problem of excessive temperature between the inner furnace body 3 and the outer furnace body 1 affecting the operation of the equipment during long-term work.

[0025] Reference Figure 2As shown in the structure, outer support rails 17 are symmetrically provided at both ends of the inner side of the outer furnace body 1, and inner support rails 31 are symmetrically provided at both ends of the outer side of the inner furnace body 3, and then a plurality of support balls 32 are provided between the outer support rails 17 and the inner support rails 31. By providing the support balls 32, the inner furnace body 3 can be supported, and the inner furnace body 3 can be ensured to rotate in the outer furnace body 1, so that the inner furnace body 3 can achieve more uniform heating and melting of the scrap metal inside during the smelting process. Specifically, inner rotating gear teeth 30 are provided on the outer side of the inner furnace body 3, and then a rotating motor 14 is provided inside the equipment room 10 below the outer furnace body 1, and a driving gear 15 is provided on the output end of the rotating motor 14. During installation, the driving gear 15 is meshed with the inner rotating gear teeth 30. During operation, the driving gear 15 is driven to rotate by the rotating motor 14, and then the inner furnace body 3 meshed with the driving gear 15 is driven to rotate, thereby ensuring that the scrap metal achieves a better melting effect when it is melted.

[0026] Reference Figure 4 As shown in the structure, a number of compression springs 41 are arranged in a rectangular array on the side of the compression plate 4 close to the sealing door 2. The compression spring 41 is "conical". The end of the compression spring 41 with a larger diameter is connected to the compression plate 4, and the end of the compression spring 41 with a smaller diameter is connected to the sealing door 2. When the sealing door 2 is closed, the sealing plate 5 on one side of the compression plate 4 will abut and seal with the end of the inner furnace body 3. At this time, the sealing plate 5 and the inner furnace body 3 are compressed under the action of the compression spring 41, which can avoid leakage when the scrap metal is melted.

[0027] Reference Figure 5 As shown in the structure, the sealing plate 5 is rotatably connected to the pressing plate 4 through a rotating disk 51 provided on one side, and a sealing ball 50 is provided between the sealing plate 5 and the pressing plate 4 to ensure that the sealing plate 5 rotates with the inner furnace body 3 during the rotation of the inner furnace body 3, thereby better ensuring that a good sealing effect can still be achieved during the rotation.

[0028] Similarly, while ensuring the sealing of the inner furnace body 3, it is necessary to ensure the effect of the sealing door 2 on the sealing plate 5. Therefore, a closed fixing plate 12 is set on one side of the outer furnace body 1, and a fixed rotating shaft 13 is symmetrically rotated on the closed fixing plate 12. Then, a fixed rotating ear 131 is threadedly connected to the fixed rotating shaft 13, and then a closed pressing plate 21 is set on one side of the sealing door 2. At the same time, a pressing limit 210 is symmetrically opened on the closed pressing plate 21. After the sealing door 2 is closed, the fixed rotating shaft 13 is clamped in the pressing limit 210 and then tightened and fixed by the fixed rotating ear 131.

[0029] Working principle of the present invention:

[0030] During operation, the scrap metal to be melted is placed in the inner furnace body 3, and then the sealed door 2 is closed by clamping the fixed rotating shaft 13 into the clamping limit 210, and then tightening and fixing it through the fixed rotating ear 131. At this time, the electric heating rack 6 inside the inner furnace body 3 is opened to melt the scrap metal inside the inner furnace body 3. During the melting process, the rotating motor 14 drives the driving gear 15 to rotate and then drives the inner furnace body 3 meshing with the driving gear 15 to rotate, ensuring that the scrap metal achieves a better melting effect when melting. After the melting is completed, it is left to cool. After cooling is completed, the smelted and fixed metal can be taken out.

[0031] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
