Description

Technical Field

[0001] This invention relates to a furnace hearth, specifically a movable furnace hearth with accelerated heating function, belonging to the technical field of blast furnace hearths. Background Technology

[0002] In existing metal smelting or recycling processes, the furnace hearth is generally fixed in the following way: the lower end of the designed furnace hearth is fixed to a concrete base with a support seat, and the upper end is connected to the furnace body, which is not convenient to move.

[0003] Chinese patent application number CN201320158934.9 proposes a movable furnace cylinder. The furnace cylinder is placed on a support frame, which is supported by jacks and placed on a trolley. The bottom of the trolley has steel rails on both sides, and the two sides of the trolley are guided and connected to the steel rails by several guide wheels. The fixed concrete method has been changed to a movable method, which is convenient to replace, does not require the removal of the furnace body water jacket, and is quick to replace, requiring only about 2 hours. This reduces furnace downtime and improves production efficiency.

[0004] Although it has a movable structure, it lacks rapid heating capability and has poor functionality.

[0005] A Chinese invention patent with application number CN202110981994.X discloses a furnace hearth accelerated heating device. It connects an external gas supply pipe to a flexible hose, and the gas in the hose enters the heater through an annular frame to provide fuel for the heater. The extension rod of the electric push rod extends, causing the concave column to rotate, which in turn drives the outlet of the heater to swing upward, facilitating the heating of the bottom of the blast furnace. The contact plate squeezes the igniter to ignite the heater, causing the gas in the heater to burn and spray flames. The heat is concentrated at the bottom of the blast furnace through the heat-resistant cylinder, thereby achieving the purpose of accelerated heating.

[0006] Although it has a good heating effect, the ignition position is fixed and cannot be moved, the heating efficiency is not high enough and not uniform enough, and it does not have the function of cleaning impurities on the inner wall of the furnace, which limits its use. Therefore, we propose an optimized and improved movable furnace with accelerated heating function. Summary of the Invention

[0007] The purpose of this invention is to provide a movable furnace cylinder with accelerated heating function to solve the above problems. It is easy to move, has a uniform heating effect, a fast heating speed, and facilitates the crushing and cleaning of internal impurities, making it suitable for widespread use.

[0008] The present invention achieves the above-mentioned objectives through the following technical solution: a movable furnace cylinder with accelerated heating function, comprising a furnace cylinder body, a movable base, adjustable movable wheels, a vent seat, a height-adjustable integrated heating and cleaning assembly, a multi-section hollow pipe, a winding mechanism, and an integrated hammering, piercing, and flame-spraying assembly. The movable base is fixedly disposed at the bottom of the furnace cylinder body, and the adjustable movable wheels are fixedly installed on the outer side of the movable base in a circular array. The vent seat is welded to the outer wall of the bottom side of the furnace cylinder body.

[0009] The multi-segment hollow pipe is fixedly installed at the center of the bottom of the furnace body cavity. The height-adjustable heating and cleaning integrated assembly is fixedly installed on the top of the multi-segment hollow pipe. The winding mechanism is located on the top of the height-adjustable heating and cleaning integrated assembly. The hammering, piercing, and flame-spraying integrated assembly is installed at the telescopic end of the height-adjustable heating and cleaning integrated assembly.

[0010] Preferably, the adjustable movable wheel includes a mounting base, a movable bracket, rollers, and a hydraulic telescopic rod. The mounting base is installed on the bottom outer wall of the movable base by fixing bolts. The hydraulic telescopic rod is fixedly installed on one side of the bottom of the mounting base. The movable bracket is welded to the bottom of the mounting base. The movable bracket has a built-in drive motor. The rollers are rotatably installed in the movable bracket and connected to the output shaft of the drive motor.

[0011] By adopting the above scheme, the motor built into the mobile support can drive the rollers to rotate, thereby driving the overall movement of the device. The extension and retraction of the hydraulic telescopic rod can be controlled by the friction between its extension end and the ground. When the extension and retraction of the hydraulic telescopic rod is not needed, the entire device can be lifted up, and the rollers can be suspended in the air without contacting the ground, thereby stopping the movement of the device, making the structure more stable.

[0012] Preferably, the vent seat is provided with an air inlet, and a gas connecting pipe is provided through the side wall of the furnace body. The vent seat is connected to the multi-section hollow pipe through the gas connecting pipe.

[0013] By adopting the above scheme, external gas can enter the vent seat through the air inlet, and then be introduced into the multi-section hollow pipe through the gas connecting pipe. After passing through the height-adjustable heating and cleaning integrated component, it is delivered to each hammering, piercing and flame-spraying integrated component and then sprayed out to accelerate the heating inside the furnace hearth. Both the hammering, piercing and flame-spraying integrated component and the height-adjustable heating and cleaning integrated component are lifting structures, which can be raised and lowered inside the furnace hearth, including the blast furnace, thereby accelerating the heating of various parts inside the blast furnace. The heating efficiency is high and the heating effect is good.

[0014] Preferably, the height-adjustable heating and cleaning integrated assembly includes a hexagonal disc, a hollow elastic connecting rod, and a conical seat. The hexagonal disc is hollow and is welded to and communicates with the top of the multi-segment hollow pipe. The conical seat is welded to the top of the hexagonal disc. The winding mechanism is connected to the top of the conical seat. The hollow elastic connecting rod is welded to the outer side of the hexagonal disc and communicates with the inner cavity. The hammering, piercing, and flame-spraying integrated assembly is installed on the telescopic end of the hollow elastic connecting rod.

[0015] By adopting the above scheme, the integrated hammering, piercing, and flame-spraying assembly can extend and retract along with the extension and retraction of the hollow elastic connecting rod. In actual use, the extension and retraction of the hollow elastic connecting rod is related to the gas intake pressure. When the intake pressure is high, the hollow elastic connecting rod extends, and vice versa. By controlling the position of the integrated hammering, piercing, and flame-spraying assembly through changes in intake pressure, the assembly can be raised and lowered to accelerate heating of various positions within the furnace body. It can also extend to hammer and crush impurities on the inner wall of the furnace body, facilitating the maintenance of the furnace body and enhancing its functionality.

[0016] Preferably, the hollow elastic connecting rod includes a fixed pipe, a sealing ring, a telescopic pipe, and a return spring. The fixed pipe is welded to the outer wall of the hexagonal disc and communicates with the inner cavity. The sealing ring is movably disposed inside the fixed pipe, and one end of the sealing ring is connected to the inner wall of the fixed pipe through the return spring. The telescopic pipe is disposed on the sealing ring, and the hammering, piercing, and flame-spraying integrated assembly is fixedly disposed on the telescopic pipe.

[0017] By adopting the above scheme, the telescopic pipe moves with the movement of the sealing ring, and the sealing ring moves with the change of gas intake pressure. When the force of the gas intake pressure is greater than the tension of the return spring, it extends; when the force of the gas intake pressure is less than the tension of the return spring, it retracts, thus realizing the position control of the hammering, piercing and flame-spraying integrated component.

[0018] Preferably, the winding mechanism includes a motor base, a winding rod, and ultra-high temperature resistant 310S stainless steel wire. The motor base is located on the top of the blast furnace body, the winding rod is connected to the motor output shaft built into the motor base, and the ultra-high temperature resistant 310S stainless steel wire is wound on the winding rod.

[0019] By adopting the above solution, the motor built into the motor base can drive the winding rod to rotate, thereby controlling the winding of the ultra-high temperature resistant 310S stainless steel wire. This is used to adjust the height of the height-adjustable heating and cleaning integrated component and the hammering, piercing, and flame-spraying integrated component.

[0020] Preferably, the hammering, piercing, and flame-spraying integrated assembly includes an arc-shaped plate, a jet seat, a fixing rod, a cone-shaped spike, and a striking block. The arc-shaped plate and the jet seat are both hollow structures. The arc-shaped plate is welded to one end of the telescopic pipe and communicates with it. The jet seat is welded to the top of the arc-shaped plate and communicates with it. The top of the jet seat has a jet hole.

[0021] By adopting the above scheme, the arc plate and the jet seat can receive the gas from the vent seat and spray it out through the jet hole. In actual use, the gas is ignited by the igniter built into the blast furnace. Then, as the gas is sprayed out, it can accelerate the heating of various parts of the hearth body.

[0022] Preferably, the fixing rod is welded to the side wall of the arc-shaped plate, and the cone and the striking block are arranged alternately on each of the fixing rods.

[0023] By adopting the above scheme, when the integrated hammering, piercing and flame-spraying assembly is extended and retracted, both the cone and the striking block can strike the side wall of the furnace body. The striking effect of the striking block can crack the impurities attached to the furnace body, and the cone can separate the cracked impurities, thereby achieving a better impurity cleaning effect.

[0024] The beneficial effects of this invention are as follows: the external gas can enter the ventilation seat through the air inlet, and then be introduced into the multi-section hollow pipe through the gas connecting pipe. After passing through the height-adjustable heating and cleaning integrated component, it is delivered to each hammering, piercing and flame-spraying integrated component and then sprayed out to accelerate the heating inside the furnace hearth body. Moreover, both the hammering, piercing and flame-spraying integrated component and the height-adjustable heating and cleaning integrated component are lifting structures, which can be raised and lowered inside the furnace hearth body, including the blast furnace, thereby accelerating the heating of various parts inside the blast furnace. The heating efficiency is high and the heating effect is good.

[0025] The hammering, piercing, and flame-spraying integrated assembly of the present invention extends and retracts with the extension and retraction of the hollow elastic connecting rod. When the gas intake pressure is high, the hollow elastic connecting rod extends, and vice versa. By changing the intake pressure, the position of the hammering, piercing, and flame-spraying integrated assembly is controlled, so that the hammering, piercing, and flame-spraying integrated assembly can be raised and lowered to accelerate the heating of various positions inside the furnace body, and can also extend to knock and crush impurities on the inner wall of the furnace body, which facilitates the maintenance of the furnace body and enhances its functionality.

[0026] When the hammering, piercing, and flame-spraying integrated assembly of the present invention is extended and retracted, both the cone and the striking block can strike the side wall of the furnace body. The striking effect of the striking block can cause impurities attached to the furnace to be cracked, and the cone can separate the cracked impurities, thereby achieving a better impurity cleaning effect.

[0039] A movable furnace cylinder with accelerated heating function includes a furnace cylinder body 1, a movable base 2, adjustable movable wheels 3, a vent seat 4, a height-adjustable integrated heating and cleaning assembly 5, a multi-section hollow pipe 6, a winding mechanism 7, and an integrated hammering, piercing, and flame-spraying assembly 8. The movable base 2 is fixedly installed at the bottom of the furnace cylinder body 1. The adjustable movable wheels 3 are fixedly installed on the outer side of the movable base 2 in a circular array. The vent seat 4 is welded to the outer wall of one side of the bottom of the furnace cylinder body 1.

[0040] A multi-segment hollow pipe 6 is fixedly installed at the center of the bottom of the inner cavity of the furnace body 1. A height-adjustable heating and cleaning integrated component 5 is fixedly installed on the top of the multi-segment hollow pipe 6. A winding mechanism 7 is set on the top of the height-adjustable heating and cleaning integrated component 5. A hammering, piercing and flame-spraying integrated component 8 is installed at the telescopic end of the height-adjustable heating and cleaning integrated component 5. An air inlet 4-1 is opened on the vent seat 4. A gas connecting pipe 4-2 is passed through the side wall of the furnace body 1. The vent seat 4 is connected to the multi-segment hollow pipe 6 through the gas connecting pipe 4-2.

[0041] In practical application of this embodiment, external gas enters the vent seat 4 through the gas inlet 4-1, and is then introduced into the multi-section hollow pipe 6 through the gas connecting pipe 4-2. After passing through the height-adjustable heating and cleaning integrated component 5, it is delivered to each hammering, piercing and flame-spraying integrated component 8 and then sprayed out to accelerate the heating within the furnace hearth body 1. Both the hammering, piercing and flame-spraying integrated component 8 and the height-adjustable heating and cleaning integrated component 5 are lifting structures, which can be raised and lowered within the furnace hearth body 1, including the blast furnace, thereby accelerating the heating of various parts within the blast furnace. The heating efficiency is high and the heating effect is good.

[0042] like Figure 7 As shown, the winding mechanism 7 includes a motor base 7-1, a winding rod 7-2, and ultra-high temperature resistant 310S stainless steel wire 7-3. The motor base 7-1 is located on the top of the blast furnace body. The winding rod 7-2 is connected to the motor output shaft built into the motor base 7-1. The ultra-high temperature resistant 310S stainless steel wire 7-3 is wound on the winding rod 7-2. In actual use of the invention, the motor built into the motor base 7-1 can drive the winding rod 7-2 to rotate, thereby controlling the winding of the ultra-high temperature resistant 310S stainless steel wire 7-3. This is used to adjust the height of the height-adjustable heating and cleaning integrated component 5 and the hammering, piercing, and flame-spraying integrated component 8.

[0043] Example 2

[0044] This embodiment further specifies the structure of the adjustable movable wheel 3 based on embodiment 1, such as... Figure 4As shown, the adjustable movable wheel 3 includes a mounting base 3-1, a movable bracket 3-2, a roller 3-3, and a hydraulic telescopic rod 3-4. The mounting base 3-1 is mounted on the bottom outer wall of the movable base 2 by fixing bolts. The hydraulic telescopic rod 3-4 is fixedly set on one side of the bottom of the mounting base 3-1. The movable bracket 3-2 is welded to the bottom of the mounting base 3-1. The movable bracket 3-2 has a built-in drive motor. The roller 3-3 is rotatably mounted in the movable bracket 3-2 and connected to the output shaft of the drive motor.

[0045] In practical application of this embodiment, in the above structural design, the motor built into the movable bracket 3-2 can drive the roller 3-3 to rotate, thereby driving the overall movement of the device. The extension and retraction of the hydraulic telescopic rod 3-4 can be controlled by the friction between its extension end and the ground. When the extension and retraction of the hydraulic telescopic rod 3-4 is not required, the entire device can be lifted up, and the roller 3-3 will be suspended in the air and not in contact with the ground, thereby stopping the movement of the device and making the structure more stable.

[0046] Example 3

[0047] This embodiment further specifies the structure of the height-adjustable heating and cleaning integrated component 5 based on Embodiment 1, such as... Figure 6 As shown, the height-adjustable heating and cleaning integrated component 5 includes a hexagonal disc 5-1, a hollow elastic connecting rod 5-2, and a conical seat 5-3. The hexagonal disc 5-1 is a hollow disc, which is welded to the top of the multi-segment hollow pipe 6 and communicates with it. The conical seat 5-3 is welded to the top of the hexagonal disc 5-1. The winding mechanism 7 is connected to the top of the conical seat 5-3. The hollow elastic connecting rod 5-2 is welded to the outer side of the hexagonal disc 5-1 and communicates with the inner cavity. The hammering, puncturing, and flame-spraying integrated component 8 is installed on the telescopic end of the hollow elastic connecting rod 5-2.

[0048] In practical application of this embodiment, in the above structural design, the hammering, piercing, and flame-spraying integrated component 8 extends and retracts with the extension and retraction of the hollow elastic connecting rod 5-2. When the gas intake pressure is high, the hollow elastic connecting rod 5-2 extends; when the gas intake pressure is low, the hollow elastic connecting rod 5-2 retracts. By changing the intake pressure, the position of the hammering, piercing, and flame-spraying integrated component 8 is controlled, so that the hammering, piercing, and flame-spraying integrated component 8 can rise and fall to accelerate the heating of various positions inside the furnace body 1, and can also extend to knock and crush impurities on the inner wall of the furnace body 1, facilitating the maintenance of the furnace body 1 and enhancing its functionality.

[0049] like Figure 8As shown, the hollow elastic connecting rod 5-2 includes a fixed pipe 5-4, a sealing ring 5-5, a telescopic pipe 5-6, and a return spring 5-7. The fixed pipe 5-4 is welded to the outer wall of the hexagonal disc 5-1 and communicates with the inner cavity. The sealing ring 5-5 is movably disposed inside the fixed pipe 5-4, and one end of the sealing ring 5-5 is connected to the inner wall of the fixed pipe 5-4 through the return spring 5-7. The telescopic pipe 5-6 is disposed on the sealing ring 5-5. The hammering, piercing, and flame-spraying integrated assembly 8 is fixedly disposed on the telescopic pipe 5-6. The telescopic pipe 5-6 moves with the movement of the sealing ring 5-5, and the sealing ring 5-5 moves with the change of the gas intake pressure. When the force of the gas intake pressure is greater than the tension of the return spring 5-7, it extends; when the force of the gas intake pressure is less than the tension of the return spring 5-7, it retracts, thereby realizing the position control of the hammering, piercing, and flame-spraying integrated assembly 8.

[0050] Example 4

[0051] This embodiment specifies the structure of the integrated hammering, puncture, and flame-spraying component 8 based on the above embodiments, such as... Figure 5 As shown, the hammering, piercing, and flame-spraying integrated assembly 8 includes an arc-shaped plate 8-1, a jet seat 8-2, a fixing rod 8-4, a cone-shaped spike 8-5, and a striking block 8-6. Both the arc-shaped plate 8-1 and the jet seat 8-2 are hollow structures. The arc-shaped plate 8-1 is welded to one end of the telescopic pipe 5-6 and communicates with it. The jet seat 8-2 is welded to the top of the arc-shaped plate 8-1 and communicates with it. A jet hole 8-3 is provided on the top of the jet seat 8-2. The arc-shaped plate 8-1 and the jet seat 8-2 can receive the gas from the vent seat 4 and spray it out through the jet hole 8-3. In actual use, the gas is ignited by the igniter built into the blast furnace. Then, as the gas is sprayed out, it can accelerate the heating of various positions in the hearth body 1.

[0052] like Figure 5 As shown, the fixing rod 8-4 is welded to the side wall of the arc plate 8-1. The cone spike 8-5 and the striking block 8-6 are arranged alternately on each fixing rod 8-4. When the hammering, piercing and flame-spraying integrated assembly 8 is extended and retracted, both the cone spike 8-5 and the striking block 8-6 can strike the side wall of the furnace body 1. The striking effect of the striking block 8-6 can cause the impurities attached to the furnace to be cracked. The cone spike 8-5 can then separate the cracked impurities, thereby achieving a better impurity cleaning effect.

[0053] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0054] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
