Description

Technical Field

[0002] A dust recovery device for antimony ingot smelting is a specialized device for collecting and treating the dust and gases generated during antimony smelting. Its main functions are to reduce environmental pollution, recover valuable antimony elements, and ensure the safety and environmental friendliness of the smelting process. This equipment is widely used in antimony smelters, metal smelting enterprises, and related metal recycling industries, and its application is particularly important given increasingly stringent environmental regulations. The development and application of this dust recovery device not only brings economic benefits to antimony smelting enterprises but also makes a positive contribution to environmental protection.

[0003] In existing technologies for collecting fumes and gases generated during antimony smelting, the fumes are typically cooled before being fed into a baghouse dust collector for separation and collection. During this process, the airflow needs to enter multiple filter cartridges to accelerate the filtration efficiency of impurity particles. However, this can lead to uneven airflow distribution, which may cause some filter bags to be overloaded while others are under lighter loads, affecting the overall dust removal efficiency.

[0011] Preferably, the end of the reciprocating lead screw is provided with an auxiliary component, the auxiliary component including two hexagonal rings rotatably connected to the top and bottom of the reciprocating lead screw, a plurality of rotating bars are respectively hinged around the outer wall of the hexagonal rings, and a crossbar is hinged to one end of the rotating bar.

[0012] Preferably, a piston plate is fixedly connected to one end of the crossbar, a square box is slidably connected to the outer wall of the piston plate, a cross platform is fixedly connected to one side of the outer wall of the square box, one end of the cross platform is fixedly connected to one end of the outer wall of the hexagonal threaded plate, and a heater is fixedly connected to one end of the inner wall of the square box.

[0013] Preferably, one side of the inner wall of the square box is connected to a vertical cylinder, and both ends of one side of the inner wall of the vertical cylinder are connected to a shaped ring tube frame. The inner wall of the shaped ring tube frame is respectively fitted onto the outer wall of the filter element cylinder, and multiple exhaust holes are opened on one side of the inner cavity of the shaped ring tube frame.

[0014] A method for using a dust recovery device for antimony ingot smelting process;

[0015] S1. The cooled and cooled flue gas is injected into the inside of the connecting box through the air inlet pipe. The flue gas enters the inside of the bag filter housing through the air inlet at the connecting box. During the flow of the flue gas, it is filtered by the filter cartridge. The filtered airflow enters the inside of the conical tube through the filter cartridge. The airflow enters the inside of the conical hopper through the conical tube and the six-tube cylinder. The airflow flows through the conical hopper to the top of the inner wall of the bag filter housing. The airflow is discharged to the outside through the exhaust pipe.

[0016] S2. Start the motor. The motor drives the rotating shaft and the negative pressure fan to rotate. During the rotation of the negative pressure fan, negative pressure is generated downward. The negative pressure enters the interior of multiple conical tubes through the conical bucket and the six-tube cylinder. The negative pressure enters the interior of multiple filter cartridges through multiple conical tubes, so that negative pressure is generated inside the filter cartridges at the same time, so that the airflow can be evenly distributed into the interior of the filter cartridges.

[0017] S3. When the rotating shaft rotates, it drives the fan to rotate, which disturbs the airflow and causes the dust entering the bag filter housing to flow upward along the bottom of the irregular cylinder. Through the agitation of the fan, the dust can be dispersed during the flow.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] This invention incorporates a dust collection mechanism. Cooled dust is injected into the connecting box through an inlet pipe. The dust then enters the baghouse dust collector housing through the inlet holes at the connecting box. During its flow, the dust is filtered by the filter cartridges. The filtered airflow passes through the filter cartridges into the conical tubes, then through the conical tubes and six-tube cylinders into the conical hopper. Finally, the airflow flows through the conical hopper to the top of the inner wall of the baghouse dust collector housing and is discharged through the exhaust pipe. Simultaneously, a motor is activated, driving a rotating shaft and a negative pressure fan. This fan generates negative pressure downwards, which flows through the conical hopper and six-tube cylinders into multiple conical tubes. This negative pressure then enters multiple filter cartridges, creating simultaneous negative pressure within each cartridge. This ensures even airflow distribution within the filter cartridges, allowing each cartridge to effectively participate in the filtration process and preventing localized overload or underload, thereby improving overall filtration efficiency. When the rotating shaft rotates, it drives the fan to rotate as well. The fan disrupts the airflow, causing the dust entering the bag filter housing to flow upwards along the bottom of the irregularly shaped cylinder. The fan's agitation disperses the dust during the flow, further promoting the uniformity of dust extraction from each filter cartridge. The dust is also dispersed by the fan, reducing the accumulation of large particles, thereby reducing the risk of filter cartridge clogging and extending the service life of the filter cartridges.

[0020] This invention incorporates a dust recovery mechanism. When the rotating shaft rotates, the tapered tube drives the reciprocating screw to rotate. The reciprocating screw drives the hexagonal threaded plate to move vertically up and down along the outer wall of the filter cartridge. The hexagonal threaded plate drives the fixed block and fixed ring to move up and down, and the fixed ring drives the sponge ring to move up and down. During the up and down movement, the sponge ring can clean the filter holes on the outer wall of the filter cartridge, preventing a large number of impurities in the dust from clogging the filter holes when the filter cartridge filters dust. This promotes the flow efficiency of dust in the equipment. Furthermore, when the sponge ring moves up and down, it can scrape off the impurities adhering to the outer wall of the filter cartridge, causing the impurities to fall off, thereby improving the equipment's efficiency in recovering impurities from the dust.

[0021] This invention, through the establishment of a dust recovery mechanism, allows the hexagonal threaded plate to gradually approach the hexagonal ring as it rises and falls. The resulting pressure causes the hexagonal ring to drive the rotating bar and crossbar to move laterally along the inner wall of the square box. The crossbar then drives the piston plate to move laterally inside the square box, allowing the airflow in the rodless area inside the square box to enter the interior of the vertical cylinder. The airflow then enters the interior of the irregularly shaped ring tube frame through the vertical cylinder and is discharged outward through multiple exhaust holes opened at the irregularly shaped ring tube frame. This effectively removes impurity particles remaining on the top of the sponge ring, improving the recovery effect of impurities in the dust. Furthermore, the heater heats the airflow, and as the heated airflow is discharged outward through the exhaust holes, it dries the impurity particles adhering to the outer wall of the filter cartridge and the sponge ring. This reduces the moisture content of the impurity particles, decreases their adhesion, and indirectly improves the scraping efficiency of the sponge ring on impurity particles, thus accelerating the filtration and separation efficiency of the filter cartridge for dust.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1 to 10 As shown, the present invention provides a dust recovery device for antimony outlet during antimony ingot smelting, including a bag filter housing 1, a connecting box 2 fixedly connected to one side of the outer wall of the bag filter housing 1, an air inlet pipe 3 connected to one side of the inner wall of the connecting box 2, an exhaust pipe 4 connected to the side of the bag filter housing 1 away from the connecting box 2, an air inlet hole 6 opened on one side of the bottom of the inner wall of the connecting box 2, one end of the air inlet hole 6 extending into the interior of the bag filter housing 1, and also including;

[0035] The dust collection mechanism 5 includes a motor 51 fixedly connected to the top of the bag filter housing 1. A rotating shaft 52 is fixedly connected to the output end of the motor 51. A fixed platform 53 is fixedly connected to the top of the inner wall of the bag filter housing 1. A separation component 54 is provided on the inner wall of the fixed platform 53 for separating dust particles in the dust.

[0036] The above scheme is adopted as follows: the motor 51 is started, and the motor 51 drives the rotating shaft 52 and the negative pressure fan 545 to rotate. During the rotation of the negative pressure fan 545, negative pressure is generated downward. The negative pressure enters the interior of multiple conical tubes 542 through the conical bucket 544 and the six-tube cylinder 543. The negative pressure enters the interior of multiple filter cartridges 541 through the multiple conical tubes 542 respectively, so that negative pressure is generated inside the filter cartridges 541 at the same time, so that the airflow can be evenly distributed into the interior of the filter cartridges 541, and each filter cartridge 541 can effectively participate in the filtration process.

[0037] The separation assembly 54 includes filter cartridges 541 fixedly connected to the inner wall of the fixed platform 53. There are eighteen filter cartridges 541. A conical tube 542 is fixedly connected to the top of the inner wall of the filter cartridge 541. The top of the conical tube 542 is connected to a six-tube cylinder 543. The top of the middle end of the six-tube cylinder 543 is connected to a conical bucket 544.

[0038] The above scheme is adopted as follows: the cooled and cooled dust is injected into the interior of the connecting box 2 through the air inlet pipe 3. The dust enters the interior of the bag filter housing 1 through the air inlet 6 at the connecting box 2. During the dust flow, it is filtered by the filter cartridge 541. The filtered airflow enters the interior of the conical tube 542 through the filter cartridge 541. The airflow enters the interior of the conical hopper 544 through the conical tube 542 and the six-tube cylinder 543. The airflow flows through the conical hopper 544 to the top of the inner wall of the bag filter housing 1. The airflow is discharged to the outside through the exhaust pipe 4.

[0039] A negative pressure fan 545 is fixedly connected to the top outer wall of the rotating shaft 52. The negative pressure fan 545 is located inside the conical bucket 544. One end of the rotating shaft 52 passes through the fixed platform 53 and extends to the bottom of the inner wall of the bag filter housing 1. A fan 546 is fixedly connected to the bottom outer wall of the rotating shaft 52. Four fixed rods 548 are fixedly connected around the bottom of the inner wall of the bag filter housing 1. A special-shaped cylinder 547 is fixedly connected between the four fixed rods 548. The fan 546 is entirely located inside the special-shaped cylinder 547.

[0040] The above scheme is adopted: when the rotating shaft 52 rotates, it drives the fan 546 to rotate. While the fan 546 disturbs the airflow, it causes the dust entering the bag filter housing 1 to flow upward along the bottom of the irregular cylinder 547. Through the agitation of the fan 546, the dust can be dispersed during the flow, which further promotes the uniformity of dust suction of each filter cylinder 541. The dust is also dispersed under the agitation of the fan 546, reducing the accumulation of large particles.

[0041] A cleaning component 55 is provided at one end of the rotating shaft 52. The cleaning component 55 includes a reciprocating screw 551 fixedly connected to the outer wall of the rotating shaft 52 near the fan 546. A hexagonal threaded plate 552 is threadedly connected to the outer wall of one end of the reciprocating screw 551.

[0042] The top of the hexagonal threaded plate 552 has multiple round holes, the inner wall of which is slidably connected to the outer wall of one end of the filter cartridge 541, and multiple fixing blocks 553 are fixedly connected to the outer wall of the hexagonal threaded plate 552.

[0043] One end of the fixing block 553 is fixedly connected to a strip plate 554, and four fixing rings 555 are fixedly connected between two adjacent strip plates 554. A sponge ring 556 is fixedly connected to the inner wall of the fixing ring 555, and the inner wall of the sponge ring 556 is slidably connected to the outer wall of the filter cartridge 541.

[0044] Using the above scheme: when the rotating shaft 52 rotates, the tapered tube 542 drives the reciprocating screw 551 to rotate, the reciprocating screw 551 drives the hexagonal threaded plate 552 to move vertically up and down along the outer wall of the filter element cylinder 541, the hexagonal threaded plate 552 drives the fixed block 553 and the fixed ring 555 to move up and down, the fixed ring 555 drives the sponge ring 556 to move up and down, and the sponge ring 556 can clean the filter holes on the outer wall of the filter element cylinder 541 during the up and down process.

[0045] like Figures 1 to 10 As shown, an auxiliary component 56 is provided at the end of the reciprocating screw 551. The auxiliary component 56 includes two hexagonal rings 561 rotatably connected to the top and bottom of the reciprocating screw 551. Multiple rotating bars 562 are hinged around the outer wall of the hexagonal rings 561 respectively. A crossbar 563 is hinged to one end of each rotating bar 562.

[0046] A piston plate 564 is fixedly connected to one end of a crossbar 563. A square box 565 is slidably connected to the outer wall of the piston plate 564. A cross platform 567 is fixedly connected to one side of the outer wall of the square box 565. One end of the cross platform 567 is fixedly connected to one end of the outer wall of a hexagonal threaded plate 552. A heater 566 is fixedly connected to one end of the inner wall of the square box 565.

[0047] A vertical cylinder 568 is connected to one side of the inner wall of the square box 565. Both ends of the inner wall of the vertical cylinder 568 are connected to a shaped ring tube frame 569. The inner wall of the shaped ring tube frame 569 is respectively fitted onto the outer wall of the filter element cylinder 541. Multiple exhaust holes 5610 are opened on one side of the inner cavity of the shaped ring tube frame 569.

[0048] The above scheme is adopted as follows: When the hexagonal threaded plate 552 rises and falls, it gradually approaches the hexagonal ring 561. The resulting extrusion force causes the hexagonal ring 561 to drive the rotating bar 562 and the crossbar 563 to move laterally on the inner wall of the square box 565. The crossbar 563 further drives the piston plate 564 to move laterally inside the square box 565, causing the airflow in the rodless area inside the square box 565 to enter the vertical cylinder 568. The airflow then enters the irregular ring tube frame 569 through the vertical cylinder 568 and is discharged outward through multiple exhaust holes 5610 opened on the irregular ring tube frame 569, thereby spraying the impurity particles remaining on the top of the sponge ring 556.

[0049] Working principle and usage process of this invention:

[0050] The cooled flue gas is injected into the interior of the connecting box 2 through the air inlet pipe 3. The flue gas enters the interior of the bag filter housing 1 through the air inlet 6 at the connecting box 2. During the flow of the flue gas, it is filtered by the filter cartridge 541. The filtered airflow enters the interior of the conical tube 542 through the filter cartridge 541. The airflow enters the interior of the conical hopper 544 through the conical tube 542 and the six-tube cylinder 543. The airflow flows through the conical hopper 544 to the top of the inner wall of the bag filter housing 1. The airflow is discharged outward through the exhaust pipe 4. During this process, the motor 51 is started, which drives the rotating shaft 52 and the negative pressure fan 545 to rotate. As the negative pressure fan 545 rotates, it generates negative pressure downwards. The negative pressure enters the interior of multiple conical tubes 542 through the conical bucket 544 and the six-tube cylinder 543. The negative pressure then enters the interior of multiple filter cartridges 541 through the multiple conical tubes 542, causing negative pressure to be generated inside the filter cartridges 541 simultaneously. This allows the airflow to be evenly distributed inside the filter cartridges 541, ensuring that each filter cartridge 541 can effectively participate in the filtration process. This avoids local overload or underload, thereby improving the overall filtration efficiency. When the rotating shaft 52 rotates, it drives the fan 546 to rotate. While the fan 546 disturbs the airflow, it causes the dust entering the bag filter housing 1 to flow upward along the bottom of the irregularly shaped cylinder 547. Through the agitation of the fan 546, the dust can be dispersed during the flow, further promoting the uniformity of dust suction in each filter cartridge 541. The dust is dispersed under the agitation of the fan 546, reducing the accumulation of large particles, thereby reducing the risk of clogging of the filter cartridge 541 and extending the service life of the filter cartridge 541.

[0051] When the rotating shaft 52 rotates, the tapered tube 542 drives the reciprocating screw 551 to rotate. The reciprocating screw 551 drives the hexagonal threaded plate 552 to move vertically up and down along the outer wall of the filter element cylinder 541. The hexagonal threaded plate 552 drives the fixed block 553 and the fixed ring 555 to move up and down. The fixed ring 555 drives the sponge ring 556 to move up and down. During the up and down process, the sponge ring 556 can clean the filter holes on the outer wall of the filter element cylinder 541, preventing a large number of impurity particles in the dust from clogging the filter holes of the filter element cylinder 541 when filtering dust, thus promoting the flow efficiency of dust in the equipment. When the sponge ring 556 moves up and down, it can scrape off the impurity particles attached to the outer wall of the filter element cylinder 541, causing the impurity particles to fall off, thereby improving the equipment's efficiency in recovering impurities from dust.

[0052] When the hexagonal threaded plate 552 is raised or lowered, it gradually approaches the hexagonal ring 561. The resulting compressive force causes the hexagonal ring 561 to drive the rotating bar 562 and the crossbar 563 to move laterally along the inner wall of the square box 565. The crossbar 563 drives the piston plate 564 to move laterally inside the square box 565, allowing the airflow in the rodless area inside the square box 565 to enter the interior of the vertical cylinder 568. The airflow then enters the interior of the irregular annular tube frame 569 through the vertical cylinder 568, and finally passes through multiple exhaust holes 5610 opened at the irregular annular tube frame 569. The air is discharged outwards, thereby spraying out impurity particles that remain on the top of the sponge ring 556, improving the recovery effect of impurities in the flue gas. Furthermore, the airflow is heated by the heater 566. As the heated airflow is discharged outwards through the exhaust port 5610, it can dry the impurity particles that adhere to the outer wall of the filter cartridge 541 and the sponge ring 556. This reduces the moisture content of the impurity particles and reduces their adhesion, thereby improving the scraping efficiency of the sponge ring 556 on impurity particles and accelerating the filtration and separation efficiency of the filter cartridge 541 on the flue gas.

10. A method for using a dust recovery device at the antimony outlet during antimony ingot smelting, characterized in that: Application of the antimony ingot smelting process antimony outlet dust recovery device as described in claim 3: S1. The cooled and cooled dust is injected into the interior of the connecting box (2) through the air inlet pipe (3). The dust enters the interior of the bag filter housing (1) through the air inlet hole (6) at the connecting box (2). During the dust flow, it is filtered by the filter cartridge (541). The filtered airflow enters the interior of the conical tube (542) through the filter cartridge (541). The airflow enters the interior of the conical bucket (544) through the conical tube (542) and the six-tube cylinder (543). The airflow flows to the top of the inner wall of the bag filter housing (1) through the conical bucket (544). The airflow is discharged outward through the exhaust pipe (4). S2. Start the motor (51). The motor (51) drives the rotating shaft (52) and the negative pressure fan (545) to rotate. During the rotation of the negative pressure fan (545), negative pressure is generated downward. The negative pressure enters the interior of multiple conical tubes (542) through the conical bucket (544) and the six-tube cylinder (543). The negative pressure enters the interior of multiple filter cartridges (541) through multiple conical tubes (542), so that negative pressure is generated inside the filter cartridges (541) at the same time, so that the airflow can be evenly distributed into the interior of the filter cartridges (541). S3. When the rotating shaft (52) rotates, it drives the fan (546) to rotate. While the fan (546) disturbs the airflow, the dust entering the bag filter housing (1) flows upward along the bottom of the shaped cylinder (547). Through the stirring of the fan (546), the dust can be dispersed in the flow process.
