Description

Technical Field

[0001] This utility model relates to the field of non-ferrous metallurgical equipment technology, and in particular to a dust collection and unloading device for a dust canister. Background Technology

[0002] Currently, in the copper smelting industry, dust canisters are used to hold high-temperature dust generated during the smelting and blowing processes in metallurgical furnaces and kilns. The dust temperature is generally around 250℃, the water content is generally less than 3%, and the dust contains sulfides and valuable metals.

[0003] The currently known method of unloading ash from fume hoppers involves the following steps: After the fume hopper is filled with high-temperature ash from the smelting and blowing ash silos via the gate valve, workers use forklifts to transport the full hopper to the corresponding storage area in an open or non-enclosed space for unloading. The valve at the bottom of the hopper is manually opened to release the ash. After unloading, the empty hopper is transported back to the discharge gate valve of the copper smelting and blowing ash collection silo for reloading, and this process is repeated. This method of unloading ash from fume hoppers has the following disadvantages: The ash is relatively dry and contains sulfides, generating a large amount of dust during unloading in open or non-enclosed areas, polluting the environment and endangering the health of operators, posing a risk of occupational diseases. The temperature of the ash inside the hopper and the hopper itself is high, posing a risk of burns to operators manually opening the valves during unloading. Finally, manually opening the valves for unloading is inefficient. Utility Model Content

The discharging device 20 includes a clamping member 21 and a tilting member 22. The clamping member 21 and the tilting member 22 are disposed inside the hopper body 11. The tilting member 22 is connected to the clamping member 21 and can drive the clamping member 21 to tilt. The dust removal device 30 is disposed on the hopper body 11 and connected to the dust removal port 11c, and is used to collect the ash inside the hopper body 11. The conveying device 40 includes a conveying pipe 41 and a conveying component 42. The conveying pipe 41 is provided with a conveying inlet 41a and a conveying outlet 41b. The conveying inlet 41a is sealed to the outlet of the ash discharge valve 13. The conveying component 42 is located inside the conveying pipe 41, with one end extending to the conveying inlet 41a and the other end extending to the conveying outlet 41b.

[0036] The silo 10 can refer to a closed box, within which the dust canister 200 performs ash discharge operations. In the above technical solution, the silo 10 includes a silo body 11, a silo door 12, and an ash discharge valve 13. The silo body 11 can refer to the main structure of the silo 10, and can be, but is not limited to, alloy steel, stainless steel, aluminum alloy, and composite materials, etc. The silo door 12 can refer to the structure used to open or close the inlet / outlet 11a. The opening method of the silo door 12 on the silo body 11 can be, but is not limited to, electric control, hydraulic / pneumatic control, manual control, automated linkage control, and remote / intelligent control, etc. Optionally, the silo door 12 and the silo body 11 can be a separate structure. For example, the silo door 12 and the silo body 11 can be detached. When opening the inlet / outlet 11a, the silo door 12 can be removed from the silo body 11, and when closing the inlet / outlet 11a, it can be reinstalled in the silo body 11. Optionally, the silo door 12 and the silo body 11 can also be movably connected. For example, the silo door 12 can be rotatably connected to the silo body 11, and can be, but is not limited to, a left-right rotatable connection or a right-down rotatable connection. The ash discharge valve 13 can refer to a component used to open or close the ash discharge port 11b.

[0037] The unloading device 20 refers to a device used for unloading materials from the dust canister 200, including a clamping member 21 and a tilting member 22. The clamping member 21 and the tilting member 22 are located inside the hopper body 11. The clamping member 21 can hold the dust canister 200, and the tilting member 22 is connected to the clamping member 21 and can drive the clamping member 21 to tilt. The tilting member 22 can rotate the dust canister 200 by 180°, reducing dust residue inside the dust canister 200 and improving unloading efficiency. The clamping member 21 can be, but is not limited to, a pneumatic, hydraulic, or electric gripper, and the tilting member 22 can be, but is not limited to, a motor, rotary cylinder, rotary hydraulic cylinder, or other mechanism that outputs rotary motion.

[0038] The dust removal device 30 can refer to a device for collecting dust inside the hopper 11. The connection method with the hopper 11 can be, but is not limited to, welding, bolting, riveting, etc. The dust removal device 30 may be equipped with a dust removal outlet for periodically cleaning the dust inside the dust removal device 30.

[0039] The conveying device 40 can refer to a device for conveying dust, and can be, but is not limited to, a screw conveyor, a chain conveyor, a pneumatic conveying device, or a combined conveying device, etc. As an example, the conveying device 40 can be a screw conveyor, which can be completely enclosed to prevent dust leakage, and can be arranged horizontally, inclined or vertically, which provides high flexibility and improves the reliability of the conveying device 40.

[0040] refer to Figure 3 The high-temperature dust in the ash bin 400 is generated from copper smelting and blowing, with a dust temperature of 250°C and a water content generally less than 3%. The dust contains sulfides. The dust canister 200 can collect the high-temperature dust under the gate valve 410 of the smelting and blowing ash bin 400. The dust canister 200 is generally cylindrical in shape. In the embodiment of this utility model, the valve at the bottom of the traditional dust canister can be eliminated, and a forklift part 210 and a clamping part 220 are provided. When the dust canister 200 is full of high-temperature dust, it can enter the dust canister unloading and collection device 100 for unloading. The forklift part 210 facilitates the movement of the dust canister 200 by a forklift 300, and the clamping part 220 facilitates the clamping part 21 to clamp the dust canister 200.

[0041] In the above technical solution, a full dust canister 200 can be opened through the hopper door 12 and enters the hopper body 11 near the clamping member 21. The clamping member 21 clamps the full dust canister 200 at the clamping part 220. The hopper door 12 is closed, sealing the hopper body 11. The tilting member 22 is connected to the clamping member 21 and drives the clamping member 21 to tilt the full dust canister 200 180°, emptying the dust from the dust canister 200 into the feed hopper 10. When the feed hopper 10 is full, the ash discharge valve 13 is opened, and the conveying device 40 begins to transport the dust to the conveying outlet 41b. The dust removal device 30 automatically operates and stops during the tilting of the dust canister 200, with an adjustable delay. During the dust dumping process, the dust removal device 30 collects the escaped dust, and the dust inside the dust removal device 30 can be periodically cleaned through the ash discharge valve 13. The above operation process can realize the mechanical replacement of manual labor for unloading ash from the dust canister 200. Since the dust canister 200 is always in the closed silo 10 during the unloading process, the high temperature of the ash and the dust generated during the unloading process will not affect the workers. This can improve the unloading efficiency and ensure the safety of the operators.

[0042] According to the embodiment of the present invention, the ash collection device 100 for the dust canister 200 can automatically unload ash within the closed hopper 10 through the coordinated action of the hopper 10, the unloading device 20, the dust removal device 30, and the conveying device 40. Then, the dust in the hopper 11 is collected to the outside of the ash collection device 100 by the dust removal device 30 and the conveying device 40. This can reduce the harm to operators caused by the high temperature and dust of the dust, ensure the safety of operators, improve the efficiency of ash unloading and dust collection of the dust canister 200, and thus improve the reliability of the ash collection device 100.

[0043] In some embodiments of this utility model, reference is made to Figure 1 The silo body 11 has an axial direction, which is arranged vertically. The inlet and outlet 11a and the tilting component 22 are located on opposite sides of the silo body 10 in the axial direction. The ash discharge port 11b and the dust removal port 11c are located at both ends of the silo body 11 in the axial direction, and the ash discharge port 11b is located at the bottom of the silo body 11.

[0044] As an example, "vertical direction" can be referenced. Figure 1 The up and down directions.

[0045] It is understandable that the width of the silo body 11 gradually decreases towards the end near the ash discharge port 11b, which facilitates the flow of smoke and dust to the ash discharge port 11b after they converge.

[0046] In the above technical solution, the inlet / outlet 11a and the tilting component 22 are located on opposite sides of the axial direction of the silo 10. This allows the dust canister 200 to be horizontally fed into the silo 10 from the inlet / outlet 11a, directly clamped by the clamping component 21 on the opposite side, and tilted by the tilting component 22. This reduces the movement path and improves the space utilization and efficiency of the dust canister unloading and collection equipment 100. The ash discharge port 11b and the dust removal port 11c are located at both ends of the axial direction of the silo body 11. The ash discharge port 11b is located at the bottom of the silo body 11, which facilitates the collection of dust and further improves the working efficiency of the dust canister unloading and collection equipment 100.

[0047] In some embodiments of this utility model, reference is made to Figure 1 The dust collection and unloading equipment 100 may include a transfer device 50, which is located near the inlet / outlet 11a and configured to transfer the dust canister 200 to a position inside the silo 11 near the clamping member 21.

[0048] The transfer device 50 can be, but is not limited to, a conveyor line transfer device, a robot transfer device, or a mobile transfer device, etc.

[0049] In the above technical solution, the transfer device 50 can automatically transport the dust canister 200 from the external workstation to a position inside the silo 11 near the clamping member 21, ensuring that the clamping member 21 can quickly clamp the dust canister, avoiding manual adjustment and alignment, and further improving the working efficiency of the dust canister unloading and collection equipment 100. The transfer device 50 can further improve the automation level of the dust canister unloading and collection equipment 100 and also reduce labor costs.

[0050] In some embodiments of this utility model, reference is made to Figure 1 The transfer device 50 includes a support 51 and a moving mechanism 52. The support 51 has a supporting top surface 51a, which is located above the ash discharge port 11b. The moving mechanism 52 is disposed on the supporting top surface 51a and partially passes through the inlet / outlet 11a and extends to the lower side of the clamping member 21. The material conveying device 40 is disposed below the supporting top surface 51a, and the silo door 12 is configured to seal the gap between the moving mechanism 52 and the inlet / outlet 11a.

[0051] In the above technical solution, the supporting top surface 51a can be used to support components such as the moving mechanism 52 and the dust canister 200, ensuring that the dust canister 200 can move on the supporting top surface 51a and improving the reliability of the dust canister unloading and collection equipment 100. The conveying device 40 is located on the lower side of the supporting top surface 51a, which can improve the space utilization rate of the dust canister unloading and collection equipment 100.

[0052] In some embodiments of this utility model, reference is made to Figure 1 The transfer device 50 also includes a lifting mechanism 53, which is located on the lower side of the supporting top surface 51a and is used to lift the dust canister 200 onto the moving mechanism 52. There are at least two lifting mechanisms 53, and the at least two lifting mechanisms 53 are arranged at intervals along the moving direction of the moving mechanism 52.

[0053] Understandably, the forklift 300 can move the dust canister 200 onto the lifting mechanism 53, and can also remove the dust canister 200 from the lifting mechanism 53. The lifting mechanism 53 can lift the dust canister 200 to a higher position on the moving mechanism 52, and can also transport the unloaded dust canister 200 down from the moving mechanism 52.

[0054] The number of lifting mechanisms 53 can be, but is not limited to, two, three, four, etc. Increasing the number of lifting mechanisms 53 can increase the number of loading and unloading stations in the dust canister 200, speed up the unloading cycle, and improve unloading efficiency. For example, refer to Figure 1There are two lifting mechanisms 53, which can be divided into a loading lifting mechanism 531 and a unloading lifting mechanism 532. The loading lifting mechanism 531 is the lifting mechanism 53 located away from the unloading device 20, and can be used to lift the dust canister 200 filled with ash onto the moving mechanism 52. The unloading lifting mechanism 532 is the lifting mechanism 53 located closer to the unloading device 20, and can be used to lower the dust canister 200 that has been unloaded from the moving mechanism 52. The independent operation of the loading and unloading channels avoids interference between components and improves the utilization rate of the forklift 300 and the working efficiency of the dust canister unloading and collection equipment 100.

[0055] In addition, the lifting mechanism 53 can be a hydraulic lifting mechanism, which can ensure stable power output and improve the reliability of the transfer device 50. At the same time, the lifting mechanism 53 can also be equipped with a shut-off valve to prevent oil leakage or accidental fall when the lifting mechanism 53 is de-energized, further improving the reliability of the transfer device 50.

[0056] In the above technical solution, the design of the lifting mechanism 53 allows the dust canister 200 to be moved to or removed from the moving mechanism 52, reducing direct contact between operators and the dust canister 200, preventing burns from high temperatures, and improving the reliability of the dust canister unloading and collection equipment 100. Furthermore, having at least two lifting mechanisms 53 increases the utilization rate of the forklift 300 and the working efficiency of the dust canister unloading and collection equipment 100.

[0057] In some embodiments of this utility model, reference is made to Figure 1 The moving mechanism 52 may include a flatcar body 521, a traction component 522, and a track 523. The flatcar body 521 is equipped with wheels and is powered by the traction component 522. The wheels of the flatcar body 521 travel on the track 523. The traction component 522 is driven by a winch wire rope, which is located outside the hopper 10. The track 523 is set on the support top surface 51a.

[0058] The flatcar body 521 is powered by the traction assembly 522, and the wheels of the flatcar body 521 travel on the track 523. The flatcar body 521 and the lifting mechanism 53 are provided with corresponding groove structures to ensure that the flatcar body 521 can pass through the lifting mechanism 53, and the dust canister 200 can also be transferred from the flatcar body 521 and the lifting mechanism 53.

[0059] The traction component 522 can be driven by a winch wire rope. The winch wire rope drive is located outside the hopper 10. Therefore, the flat car body 521 itself does not have a power unit, which can extend the service life of the dust canister unloading and collection equipment 100, improve the reliability of the dust canister unloading and collection equipment 100, and also help with installation, commissioning and maintenance.

[0060] In the above technical solution, the design of the flatcar body 521, traction component 522, and track 523 enables the horizontal transport of the dust canister 200 back and forth between the hopper 10 and the top dust canister 200 station of the lifting mechanism 53, improving the automation control of the dust canister unloading and collection equipment 100 and reducing labor costs. At the same time, the simple structure further reduces costs.

[0061] In some embodiments of this utility model, reference is made to Figure 1 The material discharge device 20 may include a lifting component 23, which is located inside the bin body 11 and connected to a tilting component 22 to drive the tilting component 22 to rise and fall.

[0062] It is understandable that the lifting component 23 and the tilting component 22 can be either separate structures or a single integrated structure.

[0063] In the above technical solution, the lifting component 23 can drive the tilting component 22 to rise and fall, allowing the dust canister 200 to be lifted and detached from the flatcar body 521, facilitating the tilting and unloading of the dust canister 200. The lifting component 23 is located inside the silo body 11 and connected to the tilting component 22, ensuring that only mechanical parts remain inside the silo 10, while the power unit and electrical system are located outside the silo 10. This reduces the explosion risk and equipment failure rate of the dust canister unloading and collection equipment 100, improving its reliability. Simultaneously, it also facilitates the installation, commissioning, and maintenance of the dust canister unloading and collection equipment 100.

[0064] In some embodiments of this utility model, reference is made to Figure 1 The material pouring device 20 includes a drive component 24, which is located outside the bin body 11 and drives the lifting component 23, the tilting component 22 and the clamping component 21.

[0065] The driving component 24 can refer to a component that provides power to the lifting component 23, the tilting component 22, and the clamping component 21. For example, if the lifting component 23, the tilting component 22, and the clamping component 21 are hydraulically actuated components, then the driving component 24 can be a hydraulic oil delivery mechanism. As another example, if the lifting component 23, the tilting component 22, and the clamping component 21 are electrically driven components, then the driving component 24 can be a power supply component, such as a battery pack, energy storage cabinet, etc.

[0066] In the above technical solution, the drive component 24 is located outside the hopper 11, which can extend the service life of the dust collection device 100, improve the reliability of the dust collection device 100, and also help with installation, commissioning and maintenance.

[0067] In some embodiments of this utility model, reference is made to Figure 1 The conveying device 40 also includes a humidification mechanism 43, which is located inside the conveying pipe 41 and is used to humidify the dust inside the conveying pipe 41.

[0068] The humidification unit 43 can be, but is not limited to, a high-pressure spray nozzle, a steam humidifier, an ultrasonic humidifier, etc.

[0069] In the above technical solution, the humidification mechanism 43 can increase the humidity of the dry flue gas, ensuring that the flue gas output from the conveying outlet 41b is free of dust, thereby ensuring that the flue gas after subsequent humidification will not generate dust during the transportation process of circulating into the furnace, improving the safety of operators, and further improving the reliability of the flue gas canister ash collection equipment 100.

[0070] In some embodiments of this utility model, reference is made to Figure 1 The material conveying pipe 41 is inclined, and the height of the material conveying outlet 41b relative to the ground is greater than the height of the material conveying inlet 41a relative to the ground. The material conveying component 42 is a screw conveyor.

[0071] The material conveying component 42 can be driven by a motor reducer.

[0072] In the above technical solution, the height of the material outlet 41b relative to the ground is greater than the height of the material inlet 41a relative to the ground. This prevents dry dust from flowing out of the material outlet 41b due to gravity, thus preventing dust from flying and reducing environmental pollution. It also ensures the safety of operators and improves the reliability of the dust collection and unloading equipment 100. At the same time, the material conveying component 42 is a screw conveyor, which allows the blades of the screw conveyor to rotate continuously and break up dust clumps (such as damp, agglomerated dust), preventing blockage of the material conveying pipe 41 and further improving the reliability of the dust collection and unloading equipment 100.

[0073] In some embodiments of this utility model, reference is made to Figure 1 The material conveying device 40 is provided with a connecting pipe 401, and the material conveying inlet 41a and the ash discharge valve 13 are connected by the flexible connecting pipe 401.

[0074] The material of the connecting pipe 401 can be a flexible pipe, and can be, but is not limited to, metal hoses, rubber / silicone hoses, and composite materials, etc.

[0075] In the above technical solution, the material conveying inlet 41a is connected to the ash discharge valve 13 via a flexible connecting pipe 401 to receive the dried dust from the silo 10. Simultaneously, during equipment vibration or movement, the material conveying inlet 41a and the ash discharge valve 13 can achieve a sealed connection with the connecting pipe 401, preventing dust leakage and improving the reliability of the dust collection and discharge equipment 100.

A cleaning valve is provided at the dust collector body 31, which can be used to periodically clean the dust and smoke inside the dust collector body 31.

[0084] The conveying device 40 includes a conveying pipe 41, a conveying component 42, and a humidifying mechanism 43. The conveying pipe 41 has a conveying inlet 41a and a conveying outlet 41b. The conveying inlet 41a is sealed to the outlet of the ash discharge valve 13. The conveying component 42 is disposed inside the conveying pipe 41, with one end extending to the conveying inlet 41a and the other end extending to the conveying outlet 41b. The humidifying mechanism 43 is disposed inside the conveying pipe 41 and is used to humidify the dust inside the conveying pipe 41. The conveying pipe 41 is inclined, and the height of the conveying outlet 41b relative to the ground is greater than the height of the conveying inlet 41a relative to the ground. The conveying component 42 is a screw conveyor.

[0085] The transfer device 50 includes a support 51, a moving mechanism 52, and a lifting mechanism 53. The support 51 has a supporting top surface 51a, which is located above the ash discharge port 11b. The moving mechanism 52 is disposed on the supporting top surface 51a and partially passes through the inlet / outlet 11a and extends to the lower side of the clamping member 21. The material conveying device 40 is disposed below the supporting top surface 51a, and the silo door 12 is configured to seal the gap between the moving mechanism 52 and the inlet / outlet 11a.

[0086] The moving mechanism 52 includes a flatcar body 521, a traction component 522, and a track 523. The flatcar body 521 is equipped with wheels and is powered by the traction component 522. The wheels of the flatcar body 521 travel on the track 523. The traction component 522 is driven by a winch wire rope, which is located outside the hopper 10. The track 523 is set on the support top surface 51a.

[0087] The lifting mechanism 53 includes two parts, which can be divided into a loading lifting mechanism 531 and a unloading lifting mechanism 532. The loading lifting mechanism 531 is the lifting mechanism 53 located away from the unloading device 20, and can be used to lift the dust canister 200 filled with ash onto the moving mechanism 52. The unloading lifting mechanism 532 is the lifting mechanism 53 located closer to the unloading device 20, and can be used to lower the dust canister 200 that has been unloaded from the moving mechanism 52.

[0088] The complete workflow of the dust collection and unloading equipment in the fume hood is as follows:

[0089] A full dust canister 200 is placed by a forklift 300 onto the loading end position at the bottom of the loading lifting mechanism 531. The loading lifting mechanism 531 automatically detects that the full dust canister 200 is in place. After the forklift 300 leaves, the loading lifting mechanism 531 automatically lifts the full dust canister 200 to the top position of the supporting top surface 51a. The flatcar body 521 moves below the full dust canister 200, and the loading lifting platform lowers, causing the full dust canister 200 to fall onto the flatcar body 521. The flatcar body 521 of the full dust canister 200 is moved into the bin 11 by the traction component 522 and the rail 523. The bin door 12 automatically opens and closes as the flatcar body 521 moves in and out, while also providing a sealing function. After the full dust canister 200 is delivered to the unloading position inside the bin 10 by the flatcar body 521, it is clamped by the clamping component 21. The clamping part 220 of the full dust canister 200 is lifted by the lifting component 23, making the dust canister 200 higher than the flatcar body 521. After the flatcar body 521 leaves the inside of the bin 11, the tilting component 22 tilts the full dust canister 200 180° to dump the dust inside. During the dumping process, the dust removal device 30 removes the scattered dust through the fan 32 and collects it at the dust collector body 31. After dumping, the flatcar body 521 takes away the empty dust canister 200 and moves it to the top position of the unloading lifting mechanism 532. The flatcar body 521 moves away, and the empty dust canister 200 falls onto the unloading lifting platform. The unloading lifting mechanism 532 automatically sends the empty dust canister to the ground unloading end position, and then the forklift 300 takes away the empty dust canister 200. This process is repeated continuously.

[0090] The dust removal device 30 automatically operates and stops during the tipping of the dust canister 200, with an adjustable delay. It can also periodically clean the dust inside the dust collector body 31 via the cleaning valve. When the hopper 10 is full, the ash discharge valve 13 opens, and the conveying device 40 automatically humidifies and cools the dust, transporting the humidified dust to the conveying outlet 41b. When the hopper 10 is empty, the device stops. The dust-free dust at the conveying outlet 41b is fed onto the belt conveyor via a trolley, and the belt conveyor returns the dust to the smelting furnace for recycling.
