Description

Technical Field

[0001] This utility model relates to the field of aluminum smelting furnace technology, and more specifically, to an aluminum smelting furnace with an explosion-proof mechanism. Background Technology

[0002] An aluminum smelting furnace with an explosion-proof mechanism is an industrial heating device specifically designed for melting, holding, or refining aluminum and aluminum alloy raw materials. It integrates explosion-proof safety devices to prevent and control the risk of explosions caused by flammable gases and dust within the furnace, while meeting the requirements of the aluminum smelting process. However, replacing activated carbon plates in the purification chamber using bolts and nuts in an explosion-proof aluminum smelting furnace presents several problems. From an explosion-proof performance perspective, frequent disassembly can easily lead to thread wear, damaging the gap between the mating surfaces of the explosion-proof shell and causing explosion propagation. Furthermore, substandard thread pitch tolerances or loose installation can cause components to loosen and fall off, creating safety hazards. Operationally, the confined space inside the purification chamber, especially when there are many activated carbon plates installed deep within the furnace, makes it inconvenient to use tools to disassemble and install bolts and nuts, increasing replacement time and labor intensity, resulting in low efficiency. Meanwhile, improper force can easily damage the activated carbon plate (such as cracking and deformation affecting adsorption) or the inner wall of the purification chamber, resulting in poor sealing; during disassembly and assembly, the friction and collision between the bolts and nuts and metal may generate sparks, which can easily cause an explosion in an explosion-proof environment. In addition, after repeated replacements, the sealing gasket is prone to aging and deformation. Even if the bolts are tightened, it is difficult to guarantee the airtightness of the purification chamber, which in turn affects the adsorption effect and the explosion-proof performance of the smelting furnace. Utility Model Content

[0003] To overcome the above-mentioned defects, embodiments of this utility model provide an aluminum smelting furnace with an explosion-proof mechanism, which solves the technical problem of the replacement time of activated carbon plates in the prior art.

During operation, the electric heater inside the furnace can efficiently heat aluminum and aluminum alloy raw materials, ensuring melting effect. At the same time, the spring resistance between the furnace body and the base can buffer the vibration and displacement caused by heating, maintain the stability of the furnace body, reduce the risk of equipment failure, and ensure continuous production. In terms of environmental protection, the exhaust gas generated by heating enters the purification box through the connecting pipe for treatment before being discharged, avoiding direct pollution of the environment and meeting environmental protection requirements. This not only protects the health of workers, but also helps enterprises achieve green production and enhances their environmental competitiveness. Attached Figure Description

[0025] like Figures 1-9 As shown, this invention illustrates an aluminum smelting furnace with an explosion-proof mechanism according to one embodiment of the present invention. The furnace includes a support platform 1, a purification chamber 7 fixedly mounted on the top of the support platform 1, a sliding groove 25 inside the purification chamber 7, a sealing frame 16 movably mounted inside the sliding groove 25, an activated carbon plate 28 fixedly mounted inside the sealing frame 16 (three layers), a telescopic rod 26 fixedly mounted inside the purification chamber 7, a connecting block 29 fixedly mounted on the right side of the sealing frame 16, a spring 27 fixedly mounted inside the purification chamber 7, limit holes 30 fixedly mounted on the outer side of the purification chamber 7, a limit block 12 fixedly mounted at one end of the connecting block 29 (the outer diameter of the limit block 12 is smaller than the inner diameter of the limit hole 30), an inlet pipe 14 fixedly mounted on the right side of the purification chamber 7, a valve 13 fixedly mounted at one end of the inlet pipe 14, and an outlet pipe 8 fixedly mounted on the top of the purification chamber 7.

[0026] When operating the aluminum smelting furnace equipped with an explosion-proof mechanism, after the exhaust gas generated by the furnace enters the purification chamber 7, purification liquid is first added through the liquid inlet pipe 14 fixedly installed on the right side of the purification chamber 7. At this time, the injection volume and flow rate of the purification liquid can be controlled by adjusting the valve 13 fixedly installed at one end of the liquid inlet pipe 14, so that the purification liquid can fully contact the exhaust gas and initially adsorb some harmful impurities in the exhaust gas. Subsequently, the pre-treated exhaust gas continues to flow upward, passing through the three-layer activated carbon plates 28 inside the movable sealing frame 16 inside the purification chamber 7. The activated carbon plates 28 further adsorb the residual harmful components in the exhaust gas, completing deep purification. The purified clean gas is discharged through the exhaust pipe 8 fixedly installed at the top of the purification chamber 7. When it is necessary to replace the activated carbon plates 28, the limit switch on the outside of the purification chamber 7 can be pressed. When the limiting block 12 is subjected to force, it drives the connecting block 29 fixedly connected to it to move. The connecting block 29 squeezes the spring 27 fixedly installed inside the purification box 7, causing the spring 27 to contract until the limiting block 12 is dislodged from the limiting hole 30 fixedly installed on the outside of the purification box 7. Then, the sealing frame 16 can be pulled to slide along the sliding groove 25 opened inside the purification box 7. The sealing frame 16 can be removed to replace the activated carbon plate 28. After the replacement is completed, the sealing frame 16 is pushed back into the sliding groove 25, the limiting block 12 is released, the spring 27 returns to its original position and pushes the connecting block 29, so that the limiting block 12 is locked into the limiting hole 30 again, realizing the limiting and fixing of the sealing frame 16. If the installation position of the sealing frame 16 is deviated, the telescopic rod 26 fixedly installed inside the purification box 7 can be adjusted to push the sealing frame 16 to the correct position.

[0027] After the furnace exhaust gas enters the purification chamber 7, the staff adds purification liquid through the right-side liquid inlet pipe 14, and adjusts the valve 13 at one end of the liquid inlet pipe 14 to control the injection volume and flow rate, so that the purification liquid and exhaust gas can fully contact each other and initially adsorb some harmful impurities. The pre-treated exhaust gas flows upward and passes through the three-layer activated carbon plate 28 in the internal movable sealing frame 16 to further adsorb residual harmful components and complete deep purification. The clean gas is discharged through the top exhaust pipe 8. When the activated carbon plate 28 needs to be replaced, press the outer limit block 12 of the purification chamber 7, which drives the connected connecting block 29 to move, squeezing the internal spring 27 to retract it until the limit block 12 comes out of the limit hole 30. Pull the sealing frame 16 along the slide 25 to remove it for replacement. After replacement, push back the slide 25, release the limit block 12, and the spring 27 returns to its original position to push the connecting block 29, allowing the limit block 12 to re-engage in the limit hole 30 for fixation. If the position of the sealing frame 16 is off, the internal telescopic rod 26 can be adjusted to push it back. Compared to traditional smelting furnaces, this smelting furnace adds purification liquid through the right-side inlet pipe 14. The injection volume and flow rate are controlled by adjusting the valve 13 at one end of the inlet pipe 14, allowing the purification liquid and waste gas to fully contact each other and initially adsorb some harmful impurities. The pre-treated waste gas flows upward and passes through the three-layer activated carbon plate 28 inside the internal movable sealing frame 16, further adsorbing residual harmful components to complete deep purification. The clean gas is discharged through the top outlet pipe 8. When the activated carbon plate 28 needs to be replaced, press the outer limit block 12 of the purification box 7, which drives the connected connecting block 29 to move, squeezing the internal spring 27 to contract it until the limit block 12 comes out of the limit hole 30. Pull the sealing frame 16 along the slide 25 to remove and replace it. After replacement, push back the slide 25, release the limit block 12, and the spring 27 resets and pushes the connecting block 29, allowing the limit block 12 to re-lock into the limit hole 30. If the position of the sealing frame 16 is deviated, the internal telescopic rod 26 can be adjusted to push it back into place.

[0028] In some examples, a base 2 is fixedly installed on the top of the support platform 1, a furnace body 3 is movably installed inside the base 2, a spring resistance 21 is fixedly installed between the furnace body 3 and the base 2, a sealing cover 4 is movably installed on the top of the support platform 1, a second limiting post 23 is fixedly installed on the outer surface of the furnace body 3, a first limiting post 22 is fixedly installed on the outer surface of the sealing cover 4, a limiting workpiece 24 is movably installed on the outer surface of the first limiting post 22, and one end of the limiting workpiece 24 is grooved and engaged with the outer surface of the second limiting post 23, an electric heater 20 is fixedly installed inside the furnace body 3, and a connecting pipe 6 is fixedly installed between the furnace body 3 and the purification box 7.

[0029] When operating the aluminum smelting furnace with an explosion-proof mechanism, the operator first adjusts the sealing cover 4, which is movably installed on the top of the support platform 1, to cover the furnace body 3, which is movably installed inside the base 2. Then, the operator moves the limiting workpiece 24 on the outer surface of the first limiting post 22, which is fixedly installed on the outer surface of the sealing cover 4, so that the groove at one end of the limiting workpiece 24 engages with the outer surface of the second limiting post 23, which is fixedly installed on the outer surface of the furnace body 3. This achieves a sealing and limiting relationship between the furnace body 3 and the sealing cover 4. Next, the electric heater 20, which is fixedly installed inside the furnace body 3, is started. The electric heater 20 begins to heat the aluminum and aluminum alloy raw materials inside the furnace body 3, causing them to gradually melt. During this process, the spring resistance device 21, which is fixedly installed between the furnace body 3 and the base 2, can buffer the slight vibration or positional displacement of the furnace body 3 caused by heating, ensuring the stable operation of the furnace body 3. At the same time, the exhaust gas generated during the heating process inside the furnace body 3 will enter the purification box 7 through the connecting pipe 6, which is fixedly installed between the furnace body 3 and the purification box 7, and will be discharged after purification treatment, avoiding pollution caused by direct discharge of exhaust gas.

[0030] First, adjust the sealing cover 4, which is movably installed on the top of the support platform 1, to cover the furnace body 3, which is movably installed inside the base 2. Then, move the limiting workpiece 24 outside the first limiting post 22 fixed on the outer surface of the sealing cover 4, so that one end of the limiting workpiece 24 is engaged with the second limiting post 23 fixed on the outer surface of the furnace body 3, thus achieving a sealed limit between the furnace body 3 and the sealing cover 4. Subsequently, start the electric heater 20 fixed inside the furnace body 3. The electric heater 20 heats the aluminum and aluminum alloy raw materials in the furnace, melting them. During the heating process, the spring resistance device 21 fixed between the furnace body 3 and the base 2 buffers the slight vibration or displacement of the furnace body 3 caused by heating, ensuring stable operation. At the same time, the exhaust gas generated by heating in the furnace enters the purification box 7 through the connecting pipe 6 fixed between the furnace body 3 and the purification box 7, and is discharged after purification to avoid pollution. Compared with traditional smelting furnaces, The smelting furnace achieves sealing and limiting by adjusting the sealing cover 4 on the top of the support platform 1 to cover the furnace body 3, and then by the snap-fitting of the first limiting post 22, the second limiting post 23 and the limiting workpiece 24. The steps are clear and easy to operate, and the furnace body can be sealed quickly, reducing operation time and improving work efficiency. During operation, the electric heater 20 in the furnace body 3 can efficiently heat aluminum and aluminum alloy raw materials to ensure melting effect. At the same time, the spring resistance device 21 between the furnace body 3 and the base 2 can buffer the vibration and displacement caused by heating, maintain the stability of the furnace body, reduce the risk of equipment failure, and ensure continuous production. In terms of environmental protection, the exhaust gas generated by heating enters the purification box 7 through the connecting pipe 6 for treatment before being discharged, avoiding direct pollution of the environment by exhaust gas, meeting environmental protection requirements, protecting the health of workers, helping enterprises achieve green production, and enhancing the environmental competitiveness of enterprises.

[0031] In some examples, a push rod 15 is fixedly mounted on the right side of the sealing frame 16, and the outer surface of the push rod 15 is U-shaped.

[0032] Because the U-shaped push rod 15 is fixedly installed on the right side of the sealing frame 16, when the staff replaces the activated carbon plate 28, they can pull or push the sealing frame 16 more effortlessly through the push rod 15, avoiding direct hand contact and improving the convenience and safety of operation.

[0033] In some examples, a lifting ring 5 is fixedly mounted on the top of the sealing cap 4, and the lifting ring 5 is in the form of two identical shapes.

[0034] Because two identical lifting rings 5 ​​are fixedly installed on the top of the sealing cover 4, when the staff uses lifting equipment to hook it, the sealing cover 4 can be subjected to balanced force, avoid tilting, improve the convenience of opening, closing and moving, and at the same time ensure operational safety.

[0035] In some examples, a support plate 9 is fixedly installed at the bottom of the support platform 1, and a fixing plate 10 is fixedly installed between the two support plates 9.

[0036] Since the support plate 9 is fixedly installed at the bottom of the support platform 1, and the two support plates 9 are connected by a fixed plate 10, the contact area between the equipment and the ground can be increased, the weight can be distributed, the support stability can be enhanced, and the equipment can be prevented from shifting due to vibration during melting, thus ensuring the safe operation of the equipment.

[0037] In some examples, a reinforcing rib 11 is fixedly installed at the angle between the support plate 9 and the fixing plate 10, and the reinforcing rib 11 is triangular in shape.

[0038] Since a triangular reinforcing rib 11 is fixedly installed at the angle between the support plate 9 and the fixed plate 10, the stability of the triangle can be used to strengthen the connection between the two, distribute the force, avoid deformation, further improve the load-bearing capacity of the support platform 1, and ensure the stable operation of the equipment.

[0039] In some examples, the support platform 1 has a fixing groove 17 inside, a fixing block 18 is movably installed inside the fixing groove 17, and a toolbox 19 is fixedly installed on the back of the fixing block 18.

[0040] Since the support platform 1 has a fixed groove 17 inside, and a fixed block 18 with a toolbox 19 is installed in the groove, the tools required for smelting can be conveniently stored and retrieved, and the space is saved. At the same time, the fixed block 18 ensures that the toolbox 19 is installed stably.

[0041] In some examples, the inner diameter of the fixing groove 17 is equal to the outer diameter of the fixing block 18, and the interior of the fixing groove 17 has a smooth surface design.

[0042] Since the inner diameter of the fixing groove 17 is equal to the outer diameter of the fixing block 18 and the inside is smooth, the fixing block 18 can drive the toolbox 19 to fit precisely and pull smoothly, which avoids shaking, reduces friction wear, and improves the efficiency of tool storage and retrieval.

[0043] In some examples, the spring resistance 21 is arranged in a circular array between the furnace body 3 and the base 2, and the outer shell of the spring resistance 21 is made of stainless steel.

[0044] Since the spring resistance 21 is arranged in a circumferential array between the furnace body 3 and the base 2, it can evenly distribute the vibration force of the furnace body; and its outer shell is made of stainless steel, which can prevent corrosion, resist high temperature, extend service life, and ensure stable operation of the furnace body.

[0045] In some examples, the telescopic rod 26 and the spring 27 are paired up, with a total of six pairs inside the purification chamber 7.

[0046] Since the telescopic rods 26 and springs 27 are arranged in pairs, a total of six sets, inside the purification box 7, they can act evenly on the sealing frame 16 at multiple points, which not only improves the stability of the fixation, but also allows for precise adjustment of the position, ensuring the efficient purification of the activated carbon plate 28 and reducing equipment failure.

[0047] Working principle and usage process of this utility model: When operating the aluminum smelting furnace equipped with an explosion-proof mechanism, after the exhaust gas generated by the furnace enters the purification chamber 7, purification liquid is first added through the liquid inlet pipe 14 fixedly installed on the right side of the purification chamber 7. At this time, the injection volume and flow rate of the purification liquid can be controlled by adjusting the valve 13 fixedly installed at one end of the liquid inlet pipe 14, so that the purification liquid can fully contact the exhaust gas and initially adsorb some harmful impurities in the exhaust gas. Subsequently, the pre-treated exhaust gas continues to flow upward, passing through the three-layer activated carbon plates 28 inside the movable sealing frame 16 inside the purification chamber 7. The activated carbon plates 28 further adsorb the residual harmful components in the exhaust gas, completing deep purification. The purified clean gas is discharged through the exhaust pipe 8 fixedly installed at the top of the purification chamber 7. When it is necessary to replace the activated carbon plates 28, the limit switch on the outside of the purification chamber 7 can be pressed. When the limiting block 12 is subjected to force, it drives the connecting block 29 fixedly connected to it to move. The connecting block 29 squeezes the spring 27 fixedly installed inside the purification box 7, causing the spring 27 to contract until the limiting block 12 is dislodged from the limiting hole 30 fixedly installed on the outside of the purification box 7. Then, the sealing frame 16 can be pulled to slide along the sliding groove 25 opened inside the purification box 7. The sealing frame 16 can be removed to replace the activated carbon plate 28. After the replacement is completed, the sealing frame 16 is pushed back into the sliding groove 25, the limiting block 12 is released, the spring 27 returns to its original position and pushes the connecting block 29, so that the limiting block 12 is locked into the limiting hole 30 again, realizing the limiting and fixing of the sealing frame 16. If the installation position of the sealing frame 16 is deviated, the telescopic rod 26 fixedly installed inside the purification box 7 can be adjusted to push the sealing frame 16 to the correct position.

[0048] When operating the aluminum smelting furnace with an explosion-proof mechanism, the operator first adjusts the sealing cover 4, which is movably installed on the top of the support platform 1, to cover the furnace body 3, which is movably installed inside the base 2. Then, the operator moves the limiting workpiece 24 on the outer surface of the first limiting post 22, which is fixedly installed on the outer surface of the sealing cover 4, so that the groove at one end of the limiting workpiece 24 engages with the outer surface of the second limiting post 23, which is fixedly installed on the outer surface of the furnace body 3. This achieves a sealing and limiting relationship between the furnace body 3 and the sealing cover 4. Next, the electric heater 20, which is fixedly installed inside the furnace body 3, is started. The electric heater 20 begins to heat the aluminum and aluminum alloy raw materials inside the furnace body 3, causing them to gradually melt. During this process, the spring resistance device 21, which is fixedly installed between the furnace body 3 and the base 2, can buffer the slight vibration or positional displacement of the furnace body 3 caused by heating, ensuring the stable operation of the furnace body 3. At the same time, the exhaust gas generated during the heating process inside the furnace body 3 will enter the purification box 7 through the connecting pipe 6, which is fixedly installed between the furnace body 3 and the purification box 7, and will be discharged after purification treatment, avoiding pollution caused by direct discharge of exhaust gas.
