Technical Field

[0001] This invention relates to the field of material transport protection technology, specifically to a multi-stage material transport protection device for smelting processes. Background Technology

[0002] The smelting production line is a continuous, multi-process linkage operation system. Materials need to go through multiple interconnected links such as raw material storage, crushing and screening, furnace feeding, process transfer, and finished product conveying to complete the entire process of transfer, processing and production. In the existing technology, the supporting equipment for each link of the smelting process is mostly an independent protection structure for a single section or link, that is, it is only designed for a single conveying equipment and a single working condition. However, in the multiple links of the smelting process, there are a large amount of dust and fumes, high temperature and heat, high frequency vibration and other conditions. As a result, there are a large amount of dust and fumes, high temperature and heat and working noise in the workshop where the supporting equipment in each link of the smelting process is located, which poses a significant safety risk to the workers.

[0009] Preferably, sealing gaskets are fixedly connected to both sides of the protective frame. The sealing gaskets are strip-shaped and located at the lower edge of the inclined tube.

[0010] Preferably, conveyor boxes are symmetrically fixedly connected to both sides of the base. Each conveyor box is attached to one side wall of the side cylinder. Each conveyor box is equipped with a matching screw conveyor. The screw conveyor is detachably connected to a conveying pipe. The conveying pipe is fixedly connected to one side of the conveyor box. The upper end of the conveyor box is open and a protective cover is fixedly connected to the upper end of the conveyor box. The protective cover is fixedly installed on the side cylinder, and the inclined hole is located at the top of the inner surface of the protective cover. A smooth slope is fixedly filled between the upper opening of the conveyor box and the inclined hole.

[0011] Preferably, a guide rib is fixedly connected to the upper end of the opposing sidewalls of the two side cylinders.

Each sliding rod extends into and is slidably connected to a sliding cylinder. The sliding cylinder is fixedly connected to the side cylinder.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention involves transporting multiple pieces of this equipment to various adaptable stages of the smelting process and connecting them end-to-end. Related equipment for each smelting stage is fixed within this equipment. The design of the protective frame and other structures effectively encloses the equipment at each stage of the smelting process, providing thermal insulation to protect workers and preventing the escape of dust and fumes generated during operation. A vacuum chamber is created inside the side wall of the protective frame, forming a vacuum insulation layer. A thermal insulation coating is also provided on the inner side of the side cylinder, effectively providing thermal insulation. Furthermore, the internal cavity of the side cylinder also provides movable thermal insulation, forming a triple thermal insulation system of "vacuum insulation layer + coating insulation + cavity buffer insulation." This further isolates the heat transferred from the high-temperature materials during smelting, preventing burns to personnel and pipelines outside the equipment. It provides thermal insulation and safety protection, while also offering good noise reduction. The present invention features a protruding rubber strip at the bottom of the base, which allows the protruding rubber strip to directly contact the ground, increasing the friction coefficient between the base and the ground. This prevents the equipment from slipping due to material impact or workshop crane vibration during the transfer of smelting materials. At the same time, the rubber strip has elastic buffering capacity, absorbing the vibration generated during the operation of each stage of the internal smelting process, so as to ensure the long-term operation of each stage of the smelting process in this equipment, and also plays a certain role in noise reduction. This invention starts a motor via a control platform, which drives a rotating shaft to rotate. Multiple bevel gear pairs on the shaft rotate, and the screw on the bevel gear pairs rotates, thereby driving a screw barrel threadedly connected to the screw to move up and down. The shims on the screw barrel move up and down, thereby driving the protective frame to move up and down, thus adjusting the height of the equipment. This allows it to adapt to equipment of different heights in different smelting process stages. This equipment can be used in combination to adapt to the equipment heights of different smelting process stages. When two adjacent pieces of equipment have different heights, the larger protective frame in the two adjacent protective frames may have an opening that leaks air. In this case, a special baffle is needed to block it. By using multiple pieces of equipment in combination, the corresponding supporting equipment in each stage of the smelting process can be covered and protected, thus solving the drawbacks of traditional smelting equipment operating in the open air and having scattered protection. This invention uses a conveyor belt design to enable multiple rotating shafts to rotate simultaneously, which in turn causes multiple screws to lift the pads simultaneously, thereby lifting the protective frame at the same time. This ensures that the protective frame is lifted and lowered smoothly, preventing problems such as one-sided tilting of the protective frame during lifting and lowering, and ensuring the smooth operation of the lifting work. In this invention, when the supporting equipment in each stage of the smelting process is working, a large amount of dust and fumes are generated and move upwards, eventually adhering to the top of the protective frame. The supporting equipment in the smelting process itself generates high-frequency vibrations during operation. After being weakened by the rubber strip, this high-frequency vibration becomes an acceptable vibration for the supporting equipment in each stage of the smelting process and is transmitted to the protective frame. The dust on the protective frame is shaken down and eventually falls onto the guide ribs after being guided by the irregularly shaped guide plate and accumulates. The present invention uses a dust collection fin design that makes it easier for dust to adhere to the dust collection fin. When the protective frame vibrates, the dust collection fin generates greater vibration, which can also promote the rapid falling of dust, and finally, after being guided by the irregularly shaped guide plate, it falls onto the guide rib and accumulates. The triangular strip design of this invention is to prevent some dust from accumulating on the inner protrusion of the upper end face of the side cylinder when it falls. In this way, when the dust falls, the dust at this point will be guided by the triangular strip and fall onto the guide rib to accumulate. The present invention uses a connecting rod design to limit the minimum lifting distance of the protective frame. A force sensor is set at the center of the connecting rod. When the protective frame moves to the minimum lifting distance and continues to descend, the connecting rod is subjected to force and begins to bend. The force sensor on the connecting rod receives the lateral force signal generated by the bending and transmits it to the control platform. Once the control platform receives the signal, it immediately issues a warning sound and forces the motor to stop to ensure its safety. The present invention starts the fan through the control platform. The fan generates wind and transmits the wind to each branch duct through the main air duct. After passing through the main air duct and the branch duct, the wind becomes a breeze and blows towards the top two sides of the protective frame to promote the adsorption of dust on the dust collection fins. This invention periodically controls the operation of a motor to drive the protective frame upward, and the inclined tube on the protective frame moves upward. When the inclined tube moves to the point where it is aligned with the inclined hole for conduction, the motor stops. At this time, the vibration brought to the protective frame by the operation of the supporting equipment of each link of the smelting process will cause the dust on the guide rib to fall through the inclined hole and the inclined tube to the screw conveyor in the conveying box below. The dust on the screw conveyor is then concentrated and transported by starting the screw conveyor. The present invention uses the inclined design of the guide ribs to facilitate the entry of dust on the guide ribs into the screw conveyor through the inclined holes and inclined tubes; In this invention, when the inclined hole and the inclined tube are not connected, the dust entering the inclined hole on one side of the guide rib will also be blocked by the protective frame, making it difficult for the dust to enter the screw conveyor. It is only used when the inclined hole and the inclined tube are connected. The advantage of doing so is that the screw conveyor can be started periodically according to the amount of dust generated by the corresponding smelting process equipment in the equipment. This can save energy and also make it easier for staff to centrally deal with the dust, thus saving manpower. The invention uses a sealing gasket design to prevent dust from entering the inner wall of the side cylinder through the inclined hole. Even if dust enters the side wall of the inclined hole, it will be blocked by the sealing gasket. When the inclined hole and the inclined pipe are connected, the dust will fall into the screw conveyor under the action of vibration, thus preventing dust from accumulating in the side cylinder and causing problems such as lifting jamming, structural wear, and jamming failure. In this invention, when connecting multiple devices, for screw conveyors, multiple screw conveyor blades can be connected in series with a single drive source. After multiple screw conveyors are connected in series, a drive source is installed on one side of the screw conveyor, and the conveying pipe on the conveying box of the screw conveyor on the other side is directly connected to the storage container, so that the dust in the smelting process can be transported in a concentrated manner. When the amount of dust is too large, several adjacent screw conveyors can also be connected in series as a dust collection unit, so that the dust can be stored in a concentrated manner in a distributed manner.

[0017] 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.

[0018] Please see Figures 1 to 9 The present invention provides a technical solution: A multi-stage material transport protection device for a smelting process includes a base 1. Two side cylinders 11 are symmetrically and fixedly connected to the upper surface of the base 1. A protective frame 12 extends through and is slidably connected to the two side cylinders 11. A heat-insulating coating is provided on the inner side of the two side cylinders 11. A triangular strip 13 is fixedly connected to the inner side of the upper surface of the protective frame 12. The side wall of the triangular strip 13 is attached to the inner wall of the protective frame 12. A vacuum cavity 14 is opened in the side wall of the protective frame 12. A control platform 15 is fixedly installed on the side wall of one of the side cylinders 11. A drive mechanism is provided in the base 1.

[0019] Multiple units of this equipment can be moved to various adaptable stages of the smelting process and connected end to end. Related equipment for each smelting stage is fixed within this equipment. The design of the protective frame 12 and other structures can enclose the equipment at each stage of the smelting process, providing thermal insulation to protect workers and preventing the escape of dust and fumes generated during operation. A vacuum chamber 14 is opened inside the side wall of the protective frame 12, forming a vacuum insulation layer. A thermal insulation coating is installed on the inner side of the side cylinder 11, effectively providing thermal insulation. The internal cavity of the side cylinder 11 also provides movable thermal insulation, forming a triple thermal insulation system of "vacuum insulation layer + coating insulation + cavity buffer insulation." This further isolates the heat transferred from the high-temperature materials during smelting, preventing burns to personnel and pipelines outside the equipment, providing thermal insulation and safety protection, while also achieving good noise reduction.

[0020] As an embodiment of the present invention, as shown in the figure, the bottom of the base 1 is provided with a plurality of strip grooves 2 at equal intervals, and a rubber strip 21 is inserted into each strip groove 2 with an interference fit, and the rubber strip 21 protrudes from the strip groove 2.

[0021] During operation, the protruding rubber strip 21 at the bottom of the base 1 allows it to directly contact the ground, increasing the friction coefficient between the base 1 and the ground. This prevents the equipment from slipping due to material impact or workshop crane vibration during the transfer of smelting materials. At the same time, the rubber strip 21 has elastic buffering capacity, absorbing the vibration generated during the operation of each stage of the internal smelting process, thus ensuring the long-term operation of the equipment in each stage of the smelting process within this device. It also has a certain noise reduction effect.

[0022] As an embodiment of the present invention, as shown in the figure, the driving mechanism includes a control cavity 3, which is located inside a base 1. A control groove 31 is provided on one side wall of the base 1. A motor 33 is fixedly installed in the control groove 31. The output shaft of the motor 33 is fixedly connected to a rotating shaft 32. The rotating shaft 32 extends through into the control cavity 3 and is rotatably connected to the control cavity 3. Two bevel gear pairs 34 are symmetrically connected and fixedly connected to one end of the rotating shaft 32 extending into the control cavity 3. A screw 35 is fixedly connected to each bevel gear pair 34. A screw 36 is threaded into and threadedly connected to each screw 35. Each screw 36 extends through into a side cylinder 11 and is slidably connected to the side cylinder 11. A pad 37 is fixedly connected to one end of the screw 36 extending into the side cylinder 11. The lower end of the protective frame 12 abuts against the pad 37.

[0023] During operation, the motor 33 is started via the control platform 15. The motor 33 drives the rotating shaft 32 to rotate, and multiple bevel gear pairs 34 on the rotating shaft 32 rotate. The screw 35 on the bevel gear pairs 34 rotates, thereby driving the screw barrel 36, which is threadedly connected to the screw 35, to move up and down. The pad 37 on the screw barrel 36 moves up and down, thereby driving the protective frame 12 to move up and down to adjust the height of the equipment. This allows it to adapt to equipment of different heights in the smelting process. The equipment can be used in combination to adapt to the equipment heights of different smelting process stages. When two adjacent pieces of equipment have different heights, the protective frame 12 with the larger height among the two adjacent protective frames 12 may have an opening that leaks air. In this case, a special baffle needs to be used to block it. By using multiple pieces of equipment in combination, the corresponding supporting equipment for each stage of the smelting process can be covered and protected, thus solving the drawbacks of traditional smelting equipment operating in the open air and having scattered protection.

[0024] As an embodiment of the present invention, as shown in the figure, a linkage chamber 4 is provided at one end of the base 1. Multiple rotating shafts 32 are rotatably connected in the control cavity 3. The end of each rotating shaft 32 away from the motor 33 extends through into the linkage chamber 4 and is rotatably connected to the linkage chamber 4. A conveyor belt 41 is connected between two adjacent rotating shafts 32. Multiple screw cylinders 36 on each side cylinder 11 are fixedly connected to the bottom of a pad 37. The pad 37 is slidably connected inside the side cylinder 11. A door 42 is movably installed on the linkage chamber 4.

[0025] During operation, the design of the conveyor belt 41 allows multiple rotating shafts 32 to rotate simultaneously, which in turn causes multiple screw cylinders 36 to lift the pad strip 37 simultaneously, thereby lifting the protective frame 12 at the same time. This ensures that the protective frame 12 can be lifted and lowered smoothly, preventing problems such as one-sided tilting of the protective frame 12 during lifting and lowering, and ensuring the smooth operation of the lifting work.

[0026] As an embodiment of the present invention, as shown in the figure, the side cylinder 11 is provided with an oblique hole 5, and the bottom of the protective frame 12 is fixedly connected with an oblique tube 51, which is matched.

[0027] Both sides of the protective frame 12 are fixedly connected with sealing gaskets 6. The sealing gaskets 6 are strip-shaped and are located at the lower edge of the inclined tube 51.

[0028] During operation, the sealing gasket 6 is designed to prevent dust from entering the inner wall of the side cylinder 11 through the inclined hole 5. Even if dust enters the side wall of the inclined hole 5, it will be blocked by the sealing gasket 6. When the inclined hole 5 and the inclined tube 51 are connected, the dust will fall into the screw conveyor 71 under the action of vibration, so as to prevent dust from accumulating in the side cylinder 11 and causing problems such as lifting jamming, structural wear, and jamming failure.

[0029] As an embodiment of the present invention, as shown in the figure, conveyor boxes 7 are symmetrically fixedly connected to both sides of the base 1. Each conveyor box 7 is attached to one end of the side wall of the side cylinder 11. Each conveyor box 7 is provided with a matching screw conveyor 71. The screw conveyor 71 is detachably connected to a conveying pipe 72. The conveying pipe 72 is fixedly connected to one side of the conveyor box 7. The upper end of the conveyor box 7 is set as an opening, and a protective cover 73 is fixedly connected to the upper end of the conveyor box 7. The protective cover 73 is fixedly installed on the side cylinder 11, and the inclined hole 5 is located at the top of the inner surface of the protective cover 73. A smooth slope is fixedly filled between the upper opening of the conveyor box 7 and the inclined hole 5.

[0030] A guide rib 8 is fixedly connected to the upper end of the opposing side wall of each of the two side cylinders 11. A shaped guide plate 81 is fixedly connected to the bottom side wall of one oblique hole 5 of each of the two guide ribs 8, and to one side of each guide rib 8. Multiple connecting rods 82 are fixedly connected at equal intervals on the upper side wall of the shaped guide plate 81. The upper end face of the guide rib 8 is inclined towards the oblique hole 5. The shaped guide plate 81 includes a vertical section and a slope section, and the vertical section and the slope section of the shaped guide plate 81 are fixedly connected. A force sensor is embedded in the center of the inner wall of the connecting rod 82. During operation, the supporting equipment in each stage of the smelting process generates a large amount of dust and fumes that move upwards and eventually adhere to the top of the protective frame 12. The supporting equipment in the smelting process itself generates high-frequency vibrations during operation. These high-frequency vibrations are weakened by the rubber strip 21 and become acceptable vibrations for the supporting equipment in each stage of the smelting process. These vibrations are then transmitted to the protective frame 12, causing the dust on the protective frame 12 to fall off. Finally, after being guided by the irregularly shaped guide plate 81, the dust falls onto the guide rib 8 and accumulates. The triangular strip 13 is designed to prevent some dust from accumulating on the inner protrusion of the upper end face of the side cylinder 11 when the dust falls. In this way, when the dust falls, the dust at this point will fall to the guide rib 8 through the guidance of the triangular strip 13. The connecting rod 82 is designed to limit the minimum lifting distance of the protective frame 12. A force sensor is installed at the center of the connecting rod 82. When the protective frame 12 moves to the minimum lifting distance and continues to descend, the connecting rod 82 is subjected to force and begins to bend. The force sensor on the connecting rod 82 receives the lateral force signal generated by the bending and transmits it to the control platform 15. Upon receiving the signal, the control platform 15 immediately issues a warning sound and forces the motor 33 to stop to ensure its safety.

[0031] As an embodiment of the present invention, as shown in the figure, the top two sides of the protective frame 12 are concave, and multiple dust collection fins 83 are symmetrically fixedly connected to the top two sides of the protective frame 12.

[0032] During operation, the design of the dust collection fins 83 makes it easier for dust to adhere to the dust collection fins 83. When the protective frame 12 vibrates, the dust collection fins 83 generate greater vibration, which can also promote the rapid falling of dust, and finally fall onto the guide ribs 8 after being guided by the irregular guide plate 81. The motor 33 is periodically controlled to drive the protective frame 12 to move upward. The inclined tube 51 on the protective frame 12 moves upward. When the inclined tube 51 moves to the point where it is aligned with the inclined hole 5 for conduction, the motor 33 stops. At this time, the vibration brought to the protective frame 12 by the operation of the supporting equipment of each link of the smelting process will cause the dust on the guide rib 8 to fall through the inclined hole 5 and the inclined tube 51 to the screw conveyor 71 in the conveying box 7 below. The dust on it is then transported in a concentrated manner by starting the screw conveyor 71. The inclined design of the guide rib 8 facilitates the entry of dust on the guide rib 8 into the screw conveyor 71 through the inclined hole 5 and the inclined tube 51; When the inclined hole 5 and the inclined tube 51 are not connected, the dust entering the inclined hole 5 on one side of the guide rib 8 will also be blocked by the protective frame 12, making it difficult for the dust to enter the screw conveyor 71. It is only used when the inclined hole 5 and the inclined tube 51 are connected. The advantage of doing so is that the screw conveyor 71 can be started periodically according to the amount of dust generated by the corresponding smelting process equipment in the equipment. This can save energy and also make it easier for staff to centrally deal with the dust, thus saving manpower.

[0033] As an embodiment of the present invention, as shown in the figure, the protective frame 12 is centrally and fixedly connected to a main air duct 94. The lower ends of the main air duct 94 are symmetrically and equally spacedly connected to multiple branch air ducts 95. The air outlet of each branch air duct 95 is arranged facing the dust collection fins 83. The upper end of the main air duct 94 is centrally and fixedly connected to a mounting plate 92. A fan 93 is fixedly installed on the upper end of the mounting plate 92. The fan 93 is connected to the main air duct 94 and supplies air to the main air duct 94. The mounting plate 92 is symmetrically and equally spacedly connected to multiple sliding rods 91. Each sliding rod 91 extends into and is slidably connected to a sliding cylinder 9. The sliding cylinder 9 is fixedly connected to the side cylinder 11.

[0034] During operation, the fan 93 is started through the control platform 15. The fan 93 generates air and transmits the air through the main air duct 94 to each branch air duct 95. After passing through the main air duct 94 and the branch air duct 95, the air becomes a breeze and blows towards the top two sides of the protective frame 12 to promote the adsorption of dust on the dust collection fins 83. The design of the slide cylinder 9 and the slide rod 91 allows the slide rod 91 to rise and fall synchronously inside the slide cylinder 9 when the protective frame 12 is raised and lowered, so as to further ensure the smooth movement of the protective frame 12 and the fan 93 on it. When connecting multiple devices, for the screw conveyor 71, multiple screw conveyor blades can be connected in series with only one drive source. After multiple screw conveyors 71 are connected in series, one drive source is installed on one side of the screw conveyor 71, and the conveying pipe 72 on the conveying box 7 where the screw conveyor 71 is located on the other side is directly connected to the storage container, so that the dust in the smelting process can be transported in a concentrated manner. When the amount of dust is too large, several adjacent screw conveyors 71 can also be connected in series as a dust collection unit, so that the dust can be stored in a concentrated manner in a distributed manner.

[0035] Working Principle: During operation, multiple units of this equipment are moved to various adaptable stages of the smelting process and connected end to end. Related equipment for each stage of the smelting process is fixed within this equipment. The design of the protective frame 12 and other structures effectively encloses the equipment at each stage of the smelting process, providing thermal insulation to protect personnel and preventing the escape of dust and fumes generated during operation. A vacuum chamber 14 is opened inside the side wall of the protective frame 12, forming a vacuum insulation layer. A thermal insulation coating is installed on the inner side of the side cylinder 11, effectively providing thermal insulation. The internal cavity of the side cylinder 11 also provides movable thermal insulation, forming a triple thermal insulation system of "vacuum insulation layer + coating insulation + cavity buffer insulation." This further isolates the heat transferred from the high-temperature materials during smelting, preventing burns to personnel and pipelines outside the equipment. It provides thermal insulation and safety protection, while also achieving good noise reduction. The protruding rubber strip 21 at the bottom of the base 1 allows the protruding rubber strip 21 to directly contact the ground, increasing the friction coefficient between the base 1 and the ground. This prevents the equipment from slipping due to material impact or workshop crane vibration during the transfer of smelting materials. At the same time, the rubber strip 21 has elastic buffering capacity, absorbing the vibration generated during the operation of each stage of the internal smelting process, so as to ensure the long-term operation of each stage of the smelting process in this equipment, and also plays a certain role in noise reduction. The motor 33 is started by the control platform 15. The motor 33 drives the rotating shaft 32 to rotate. Multiple bevel gear pairs 34 on the rotating shaft 32 rotate, and the screw 35 on the bevel gear pairs 34 rotates. This drives the screw barrel 36, which is threadedly connected to the screw 35, to move up and down. The pad 37 on the screw barrel 36 moves up and down, which in turn drives the protective frame 12 to move up and down to adjust the height of the equipment. This allows it to adapt to equipment of different heights in the smelting process. The equipment can be used in combination to adapt to the equipment heights of different smelting process stages. When two adjacent equipment have different heights, the protective frame 12 with the larger height among the two adjacent protective frames 12 may have an opening that leaks air. In this case, a special baffle needs to be used to block it. By using multiple equipment in combination, the corresponding supporting equipment for each stage of the smelting process can be covered and protected, thus solving the drawbacks of traditional smelting equipment operating in the open air and having scattered protection. The design of the conveyor belt 41 enables multiple rotating shafts 32 to rotate simultaneously, and ultimately enables multiple screw drums 36 to lift the pad strip 37 simultaneously, thereby lifting the protective frame 12 at the same time, so as to ensure that the protective frame 12 is lifted and lowered smoothly, and to prevent problems such as the protective frame 12 tilting on one side during lifting and lowering, and to ensure the smooth operation of the lifting work. When the supporting equipment in each stage of the smelting process is working, a large amount of dust and fumes are generated and move upwards, eventually adhering to the top of the protective frame 12. The supporting equipment in the smelting process itself generates high-frequency vibrations during operation. After being weakened by the rubber strip 21, this high-frequency vibration becomes an acceptable vibration for the supporting equipment in each stage of the smelting process and is transmitted to the protective frame 12. The dust on the protective frame 12 is shaken down and eventually falls onto the guide rib 8 after being guided by the irregular guide plate 81 and accumulates there. The design of the dust collection fin 83 makes it easier for dust to adhere to the dust collection fin 83. When the protective frame 12 vibrates, the dust collection fin 83 generates greater vibration, which can also promote the rapid falling of dust, and finally fall onto the guide rib 8 after being guided by the irregular guide plate 81. The triangular strip 13 is designed to prevent some dust from accumulating on the inner protrusion of the upper end face of the side cylinder 11 when the dust falls. In this way, when the dust falls, the dust at this point will fall to the guide rib 8 through the guidance of the triangular strip 13. The connecting rod 82 is designed to limit the minimum lifting distance of the protective frame 12. A force sensor is installed at the center of the connecting rod 82. When the protective frame 12 moves to the minimum lifting distance and continues to descend, the connecting rod 82 is subjected to force and begins to bend. The force sensor on the connecting rod 82 receives the lateral force signal generated by the bending and transmits it to the control platform 15. Upon receiving the signal, the control platform 15 immediately issues a warning sound and forces the motor 33 to stop to ensure its safety. The fan 93 is started by the control platform 15. The fan 93 generates wind and transmits the wind through the main air duct 94 to each branch air duct 95. After passing through the main air duct 94 and the branch air duct 95, the wind becomes a breeze and blows towards the top two sides of the protective frame 12 to promote the adsorption of dust on the dust collection fins 83. The motor 33 is periodically controlled to drive the protective frame 12 to move upward. The inclined tube 51 on the protective frame 12 moves upward. When the inclined tube 51 moves to the point where it is aligned with the inclined hole 5 for conduction, the motor 33 stops. At this time, the vibration brought to the protective frame 12 by the operation of the supporting equipment of each link of the smelting process will cause the dust on the guide rib 8 to fall through the inclined hole 5 and the inclined tube 51 to the screw conveyor 71 in the conveying box 7 below. The dust on it is then transported in a concentrated manner by starting the screw conveyor 71. The inclined design of the guide rib 8 facilitates the entry of dust on the guide rib 8 into the screw conveyor 71 through the inclined hole 5 and the inclined tube 51; When the inclined hole 5 and the inclined tube 51 are not connected, the dust entering the inclined hole 5 on one side of the guide rib 8 will also be blocked by the protective frame 12, making it difficult for the dust to enter the screw conveyor 71. It is only used when the inclined hole 5 and the inclined tube 51 are connected. The advantage of doing so is that the screw conveyor 71 can be started periodically according to the amount of dust generated by the corresponding smelting process equipment in the equipment. This can save energy and also make it easier for staff to centrally deal with the dust, thus saving manpower. The sealing gasket 6 is designed to prevent dust from entering the inner wall of the side cylinder 11 through the inclined hole 5. Even if dust enters the side wall of the inclined hole 5, it will be blocked by the sealing gasket 6. When the inclined hole 5 and the inclined tube 51 are connected, the dust will fall into the screw conveyor 71 under the action of vibration, so as to prevent dust from accumulating in the side cylinder 11 and causing problems such as lifting jamming, structural wear, and jamming failure. The design of the slide cylinder 9 and the slide rod 91 allows the slide rod 91 to rise and fall synchronously inside the slide cylinder 9 when the protective frame 12 is raised and lowered, so as to further ensure the smooth movement of the protective frame 12 and the fan 93 on it. When connecting multiple devices, for the screw conveyor 71, multiple screw conveyor blades can be connected in series with only one drive source. After multiple screw conveyors 71 are connected in series, one drive source is installed on one side of the screw conveyor 71, and the conveying pipe 72 on the conveying box 7 where the screw conveyor 71 is located on the other side is directly connected to the storage container, so that the dust in the smelting process can be transported in a concentrated manner. When the amount of dust is too large, several adjacent screw conveyors 71 can also be connected in series as a dust collection unit, so that the dust can be stored in a concentrated manner in a distributed manner.
