The melting furnace for metallurgy has the function of melting furnace charge.

[0003] Currently, the furnace charge can enter the melting furnace for metallurgy through a feed pipe connected to the inside of the melting furnace for metallurgy and be melted. However, due to the intermittent addition of cold furnace charge during the overall production process of the melting furnace for metallurgy, the periodic change in the temperature of the furnace charge may cause some substances in the furnace charge to soften and then harden. After multiple cycles, the furnace charge may form into a lump, resulting in blockage of the feed pipe, which is likely to affect the normal operation of the melting furnace for metallurgy.

[0014] In some embodiments, the driving assembly further includes a handle connected to the cover body and spaced from both the driving member and the feed inlet.

[0015] In some embodiments, the smelting furnace for metallurgy further includes:

[0016] A storage box fixedly connected to the aggregate hopper and located inside the aggregate hopper. The storage box is provided with a material receiving opening facing the larger-diameter end of the aggregate hopper, and is provided with a plurality of through holes communicating with the smaller-diameter end of the aggregate hopper. The stirring member is located inside the storage box.

[0017] In some embodiments, the storage box includes a cylindrical portion and a bottom sealingly connecting one end of the cylindrical portion. The open end of the cylindrical portion is configured as the material receiving opening and axially extends along the axis of the aggregate hopper.

[0024] In a smelting furnace for metallurgy, the furnace charge can enter the smelting chamber through the feed pipe of the furnace body and then be smelted to complete the normal smelting of the furnace charge. An aggregate hopper is arranged on the feed pipe, and the smaller-diameter end of the aggregate hopper is communicated with the feed pipe.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0036] It should be noted that all directional indications in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, the directional indications will also change accordingly.

[0037] In the present utility model, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0038] In addition, in the present utility model, descriptions such as "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments may be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0039] In the related art, due to the periodic temperature change of the furnace charge during the overall production process, the periodic temperature change of the furnace charge will cause some substances in the furnace charge to soften and then harden. After multiple cycles, the furnace charge may be agglomerated, so it is easy to block the material when pouring into the feed pipe, and there is a technical problem that the blocked material may affect the normal operation of the smelting furnace for metallurgy. The embodiments of the present application provide a smelting furnace for metallurgy, which can at least solve the above technical problems to a certain extent.

[0040] It should be noted that the reason for the periodic temperature change of the furnace charge during the overall production process is that in order to maintain continuous production during the production process of the furnace charge, new cold furnace charge will be regularly added to the furnace; the newly added cold furnace charge will absorb heat, resulting in a decrease in the temperature of the feed pipe, which makes the furnace charge easy to agglomerate and causes blockage of the feed pipe.

[0041] The present application will be described below with reference to the accompanying drawings:

[0042] Figure 1 shows a schematic structural diagram of a smelting furnace for metallurgy in some embodiments or certain embodiments of the present application, Figure 2 shows a side view of a smelting furnace for metallurgy in some embodiments or certain embodiments of the present application, Figure 3 shows in the present application Figure 2 the sectional view taken along the line A-A, Figure 4 shows in the present application Figure 3 the partial enlarged view at B, Figure 5 shows a schematic structural diagram of a hopper in some embodiments or certain embodiments of the present application. Combining Figures 1 to 5 , the embodiments of the present application provide a smelting furnace for metallurgy, including:

[0043] A furnace body 1, provided with a smelting cavity 101 and a feed pipe 102 communicating with the smelting cavity 101.

[0044] A hopper 2, the maximum diameter of which is larger than that of the feed pipe 102 and the smaller-diameter end of which is communicated with the feed pipe 102.

[0045] The driving assembly 3 is connected to the aggregate hopper 2 and is provided with a driving part 301 that can rotate relative to the aggregate hopper 2.

[0046] The stirring member 4 is fixedly connected to the driving part 301 and is located inside the aggregate hopper 2.

[0047] In a smelting furnace for metallurgy, the furnace charge can enter the smelting chamber 101 from the feed pipe 102 of the furnace body 1 and then be smelted to complete the normal smelting of the furnace charge. An aggregate hopper 2 is provided on the feed pipe 102. The smaller-diameter end of the aggregate hopper 2 is communicated with the feed pipe 102. Before the furnace charge enters the feed pipe 102, it can first enter the aggregate hopper 2 from the larger-diameter end of the aggregate hopper 2. The aggregate hopper 2 is connected with a driving assembly 3, and the driving part 301 of the driving assembly 3 can rotate. The rotation of the driving part 301 can drive the connected stirring member 4 to rotate. The stirring member 4 is located in the aggregate hopper 2. When the stirring member 4 rotates, it can stir the furnace charge entering the aggregate hopper 2, playing a role in breaking up the furnace charge, making the furnace charge entering the feed pipe 102 smaller in volume, reducing the possibility of blocking the feed pipe 102 due to the oversize of the furnace charge. And when the stirring member 4 rotates, it will also exert a force on the furnace charge, pushing the furnace charge to different positions in the aggregate hopper 2. The furnace charge in the aggregate hopper 2 is not easily blocked, and the furnace charge can enter the feed pipe 102 more evenly, which can also reduce the possibility of blocking the feed pipe 102. The rotating stirring member 4 can also break up the agglomerated furnace charge in the production line, reduce the blockage of the feed pipe 102 to ensure the normal operation of the feed pipe 102 and the smelting furnace for metallurgy, and to a certain extent solve the technical problem that the normal operation of the smelting furnace for metallurgy is easily affected.

[0048] Reference Figure 1 And Figure 4 , in some or certain embodiments, the driving assembly 3 may include:

[0049] A cover body 302 is covered on the larger-diameter end of the aggregate hopper 2 and is provided with a feed port 3021 communicating with the inside of the aggregate hopper 2.

[0050] A driving member 303 is connected to the cover body 302 and has a driving shaft extending into the aggregate hopper 2, and the driving shaft is configured as the driving part 301.

[0051] The cover body 302 can play a protective role for the larger-diameter end of the aggregate hopper 2. The feed port 3021 on the cover body 302 is communicated to the inside of the aggregate hopper 2, and can also control the amount of the furnace charge entering the aggregate hopper 2, so that the stirring member 4 in the aggregate hopper 2 can break up the furnace charge as much as possible to reduce the possibility of material blockage and ensure the normal operation of the smelting furnace for metallurgy. The cover body 302 can also provide an installation space for the driving member 303. The driving shaft of the driving member 303 extends into the aggregate hopper 2 and is configured as the driving part 301, which is convenient for realizing the rotation of the driving part 301, and is also convenient for the connection of the stirring member 4 and the rotation and stirring of the stirring member 4 located in the aggregate hopper 2.

[0052] It should be noted that the space inside the aggregate hopper 2 and within the aggregate hopper 2 is the space corresponding to the inner peripheral wall of the aggregate hopper 2.

[0053] In some or certain embodiments, the two ends of the aggregate hopper 2 are respectively connected to the cover body 302 and the pipe orifice of the feed pipe 102, and the axis of the aggregate hopper 2 extends along the axis of the pipe orifice. This facilitates the furnace charge to first enter the aggregate hopper 2 and then enter the pipe orifice of the feed pipe 102 from the aggregate hopper 2.

[0054] In some or certain embodiments, the connection between the cover body 302 and the aggregate hopper 2 can be a detachable connection. For example, it can be achieved through fasteners or the like. This facilitates the disassembly and assembly of the cover body 302 and the aggregate hopper 2, and also facilitates maintenance.

[0055] In some or certain embodiments, the drive assembly 3 further includes a handle 304 connected to the cover body 302 and spaced from both the drive member 303 and the feed port 3021. The addition of the handle 304 facilitates the manipulation of the handle 304 to move the cover body 302 so as to connect the cover body 302 to the aggregate hopper 2. When the cover body 302 and the aggregate hopper 2 are detachably connected, it also facilitates the separation of the cover body 302 and the aggregate hopper 2, making the operation convenient.

[0056] In some or certain embodiments, the drive member 303 can be a motor, the drive shaft can be the output shaft of the motor, and the cover body 302 can be in a shape adapted to the larger-diameter end of the aggregate hopper 2, such as a circular plate shape or the like. One or at least two handles 304 can also be provided on the cover body 302. This is easy to implement and facilitates the disassembly and assembly operation.

[0057] In some or certain embodiments, the drive member 303 in the drive assembly 3 can also include a motor or a gear drive or the like provided on the cover body 302.

[0058] Reference Figure 4 And Figure 5 , in some or certain embodiments, the metallurgical smelting furnace may further include:

[0059] A holding box 5, fixedly connected to the aggregate hopper 2 and located inside the aggregate hopper 2. The holding box 5 is provided with a material receiving opening 501 facing the larger-diameter end of the aggregate hopper 2, and is provided with a plurality of through holes 502 communicating with the smaller-diameter end of the aggregate hopper 2. The stirring member 4 is located inside the holding box 5.

[0060] The storage box 5 is located inside the aggregate hopper 2 and is provided with a material receiving opening 501 facing the larger-diameter end of the aggregate hopper 2. After the furnace charge enters the aggregate hopper 2 from the larger-diameter end of the aggregate hopper 2, it can first enter the storage box 5. The stirring member 4 in the storage box 5 rotates with the driving part 301, so that the furnace charge in the storage box 5 is squeezed and crushed. The squeezed and crushed furnace charge can enter the smaller-diameter end of the aggregate hopper 2 through the through hole 502 of the storage box 5, and then enter the feed pipe 102 from the aggregate hopper 2 and enter the metallurgical smelting furnace from the feed pipe 102. The addition of the storage box 5 is beneficial to reducing the volume of the furnace charge entering the feed pipe 102 and reducing the possibility of the feed pipe 102 being blocked.

[0061] It should be noted that since the storage box 5 is located inside the aggregate hopper 2, the stirring member 4 located inside the storage box 5 is still located inside the internal space of the aggregate hopper 2.

[0062] In some embodiments, the storage box 5 includes a cylindrical portion 503 and a bottom portion 504 that hermetically connects one end of the cylindrical portion 503. The open end of the cylindrical portion 503 is configured as the material receiving opening 501 and axially extends along the axis of the aggregate hopper 2.

[0063] This is beneficial for the storage box 5 to receive more furnace charge entering the aggregate hopper 2, and in cooperation with the stirring member 4, it can better crush the furnace charge to reduce the possibility of the feed pipe 102 being blocked.

[0064] In some embodiments, there is a cavity S between the outer peripheral wall of the cylindrical portion 503 and the inner peripheral wall of the aggregate hopper 2, and both the cylindrical portion 503 and the bottom portion 504 are provided with a plurality of through holes 502.

[0065] There is a cavity S between the cylindrical portion 503 of the storage box 5 and the inner peripheral wall of the aggregate hopper 2, and both the cylindrical portion 503 and the bottom portion 504 of the storage box 5 are provided with a plurality of through holes 502, so that the furnace charge can flow out from the through holes 502 of the cylindrical portion 503 and the bottom portion 504. The crushed furnace charge enters the feed pipe 102 more evenly, and can also reduce the possibility of the feed pipe 102 being blocked by the furnace charge, ensuring the normal operation of the metallurgical smelting furnace.

[0066] In some embodiments, the driving part 301 is shaft-shaped and axially extends into the cylindrical portion 503 along the axis of the cylindrical portion 503. A plurality of stirring members 4 are circumferentially spaced apart along the driving part 301 and contact the inner peripheral wall of the cylindrical portion 503. The stirring member 4 can stir the furnace charge, crush the furnace charge between the stirring member 4 and the inner peripheral wall of the cylindrical portion 503, and then squeeze the furnace charge into the corresponding through hole 502 of the cylindrical portion 503. The furnace charge enters the aggregate hopper 2 from the through hole 502 and then enters the feed pipe 102 from the aggregate hopper 2. The furnace charge can be squeezed into a near-powdery state, effectively reducing the possibility of the feed pipe 102 being blocked and ensuring the normal operation of the metallurgical smelting furnace.

[0067] In some embodiments, the plurality of stirring members 4 may also be arranged at intervals along the axial direction of the shaft-shaped driving portion 301. The stirring member 4 may be rod-shaped with its axis intersecting the axis of the driving portion 301. One end of the stirring member 4 may be in contact with the inner peripheral wall of the cylindrical portion 503, and the peripheral wall of the stirring member 4 near the bottom 504 may also be in contact with the bottom 504. The furnace charge can be crushed more finely, which is beneficial to reducing the possibility of blockage of the feed pipe 102 and ensuring the normal operation of the smelting furnace for metallurgy.

[0068] In some embodiments, the storage box 5 may further include an annular connecting portion 505. The annular connecting portion 505 of the storage box 5 and the bottom 504 are respectively arranged at the two axial ends of the cylindrical portion 503. The outer diameter of the annular connecting portion 505 is greater than the outer diameter of the cylindrical portion 503, and the outer diameter of the annular connecting portion 505 is connected to the aggregate hopper 2. It is convenient to realize the connection and assembly between the storage box 5 and the aggregate hopper 2.

[0069] In some embodiments, the annular connecting portion 505 and the aggregate hopper 2 are detachably connected through a flange and fasteners. It is convenient to realize the installation of the storage box 5.

[0070] In some embodiments, there may also be an included angle between the axis of the shaft-shaped driving portion 301 and the axis of the storage box 5, and the driving portion 301 is connected with the stirring member 4. The furnace charge can also be crushed.

[0071] In some embodiments, the shaft-shaped driving portion 301 may also be the driving shaft of the driving member 303. The driving member 303 may be arranged on the cover body 302 covering the larger-diameter end of the aggregate hopper 2, and two handles 304 may be respectively arranged on the cover body 302 and on both sides of the driving member 303. It is convenient for operation. The storage box 5 and the aggregate hopper 2 may also be integrally formed, and the cover body 302 in the driving assembly 3 may be connected with the annular connecting portion 505.

Figure 7 The side view of another smelting furnace for metallurgy in some embodiments or certain embodiments of the present application is shown. Figure 8 The present application is shown Figure 7 in the cross-sectional view taken along the C-C direction, in combination with Figures 6 to 8 , in some embodiments, the furnace body 1 is a rotary structure, and one end is configured as a feed end 104 communicated with the feed pipe 102, and the other end is provided with a discharge pipe 103 communicated with the smelting cavity 101 and is configured as a discharge end 105. The smelting furnace for metallurgy further includes:

[0073] A plurality of support legs 6, spaced apart from each other and one end of each being connected to the discharge end 105 of the furnace body 1, and the plurality of support legs 6 surround the discharge pipe 103.

[0074] The addition of the support legs 6 facilitates the placement of the overall smelting furnace for metallurgy, and the multiple support legs 6 surround the discharge pipe 103, which also facilitates the handling of the furnace charge flowing out of the smelting furnace for metallurgy.

[0075] In some embodiments, the smelting furnace for metallurgy further includes an anti-slip pad 7 provided at the other end of the support leg 6, which can improve the working stability of the smelting furnace for metallurgy.

[0076] In some embodiments, the smelting furnace for metallurgy further includes a discharge valve 8 disposed in the discharge pipe 103. By means of the discharge valve 8, it is convenient to control the discharge amount in the discharge pipe 103.

[0077] In some embodiments, the smelting furnace for metallurgy may further include a plurality of iron rings (not shown in the figure) and an electromagnetic heater 9. The plurality of iron rings are correspondingly arranged on the electromagnetic heater 9. The electromagnetic heater 9 is fixedly connected to the inner peripheral wall of the preheating pipe section 1021 where the feed pipe 102 extends into the smelting cavity 101 and is located within the preheating pipe section 1021. The cooperation between the iron rings and the electromagnetic heater 9 facilitates heating the inner wall of the preheating pipe section 1021, thereby playing a role in fully preheating and melting the furnace charge.

[0078] In some embodiments, the smelting furnace for metallurgy may further include a smelting cylinder 10, a winding pipe 11, an exhaust pipe 12, an inclined filter plate 13, a horizontal filter plate 14, a slag discharge pipe 15 and an air pump 16. The axis of the smelting cylinder 10 extends along the axis of the furnace body 1. The smelting cylinder can be located within the smelting cavity 101. The outer diameter of the smelting cylinder 10 is smaller than the inner diameter of the furnace body 1. The preheating pipe section 1021 of the feed pipe 102 extends into the hole formed by the inner peripheral wall of the smelting cylinder 10. The inclined filter plate 13 and the horizontal filter plate 14 are connected and jointly divide both ends of the smelting body. The inclined filter plate 13 and the horizontal filter plate 14 are both provided with through holes, and the horizontal filter plate 14 is lower than the inclined filter plate 13. The slag discharge pipe 15 and the air pump 16 communicate with the hole formed by the inner peripheral wall of the smelting cylinder 10 and are respectively arranged on both sides of the horizontal filter plate 14 along the axial direction of the smelting cylinder 10. The slag discharge pipe 15 extends out of the furnace body 1, and the air pump 16 is located outside the furnace body 1 and communicates with one end of the winding pipe 11. The winding pipe 11 is spirally wound around the outer peripheral wall of the smelting body, and the other end of the winding pipe 11 is connected to the exhaust pipe 12 extending out of the furnace body 1.

[0079] The discharge pipe 103 can be closed, and the electromagnetic heater 9 in the preheating pipe section 1021 is used to make the temperature in the preheating pipe section 1021 reach a suitable range. The furnace charge containing metal components is added into the preheating pipe section 1021 through the feed pipe 102. The furnace charge is fully preheated and melted in the preheating pipe section 1021. The preheating pipe section 1021 can be inclined. The inclined preheating pipe section 1021 enables the molten furnace charge to fall into the inner cavity of the smelting cylinder 10 for further smelting. The molten furnace charge in the inner cavity of the smelting cylinder 10 enters the lower inner cavity of the smelting cylinder 10 through the through holes in the inclined filter plate 13 for smelting. The furnace charge in the non-molten state stays on the upper surface of the inclined filter plate 13 for smelting. The furnace charge on the upper surface of the inclined filter plate 13 slides down to the upper surface of the horizontal filter plate 14 to continue smelting, which can effectively avoid the problem that the through holes of the inclined filter plate 13 are blocked due to the non-molten furnace charge and slag staying on the upper surface of the inclined filter plate 13, and is beneficial to the molten furnace charge entering the lower inner cavity of the smelting cylinder 10 for full smelting. Under the action of the air pump 16, the external air flows through the winding pipe 11 and is discharged through the exhaust pipe 12. Among them, the air flow entering the winding pipe 11 is heated, and the hot air blown into the inner cavity of the smelting cylinder 10 improves the smelting effect and efficiency. After smelting is completed, the slag discharge pipe 15 is opened, and the slag is discharged through the slag discharge pipe 15. The discharge valve 8 is opened to open the discharge pipe 103, and the smelting finished product is discharged through the discharge pipe 103

[0080] It should be noted that the inclined setting involved in this application means that there is an included angle between the axis of one structure and the axis of another structure. The aggregate hopper 2, the drive assembly 3 and the stirring member 4 in this application are not limited to being applied to the metallurgical smelting furnace with the above structure, and are applicable to any metallurgical smelting furnace provided with a smelting cavity 101 and a feed pipe 102. The smelting cylinder 10 is located in the smelting cavity 101, and the furnace charge is still smelted in the smelting cavity 101
