[0022] This utility model provides a dust recovery device for electrolytic cells, which will be described in detail below with reference to specific embodiments.

[0023] like Figure 1As shown in the figure, an embodiment of the present invention provides an electrolytic cell dust recovery device, including a device body 1, a dust filter chamber 2, a dust collection box 3, and a discharge pipe 4; the dust filter chamber 2 is disposed on the device body 1 and is used to filter the dust-laden air to obtain dust; the dust collection box 3 is disposed on the device body 1 and located below the dust filter chamber 2, and the top of the dust collection box 3 is connected to the bottom of the dust filter chamber 2 through the discharge pipe 4, for collecting the dust discharged from the dust filter chamber 2.

[0024] It should be noted that the dust collection box 3 can be located directly below or to the side of the dust filter chamber 2; there are no restrictions. Specifically, the upper end of the discharge pipe 4 can be connected to the bottom of the dust filter chamber 2, and the lower end can be connected to the top of the dust collection box 3.

[0025] In this embodiment, the dust filter chamber 2 is used to filter the inhaled dusty air to obtain dust, and the dust collection box 3 is used to collect the dust. Since the dust collection box 3 is located below the dust filter chamber 2, and the top of the dust collection box 3 is connected to the bottom of the dust filter chamber 2 through the discharge pipe 4, the dust filtered in the dust collection box 3 can be discharged into the dust collection box 3 through the discharge pipe 4 for collection. Because the dust collection box 3 itself is a box structure, that is, the inside of the dust collection box 3 is a closed space, and the connection between the dust collection box 3 and the dust filter chamber 2 is through the discharge pipe, the closedness of the path of dust discharge from the dust filter chamber 2 to the dust collection box 3 can be guaranteed, making it difficult for dust to leak out, thereby effectively preventing secondary dust pollution to the workshop environment.

[0026] Optionally, such as Figure 1 and Figure 2 As shown, the main body 1 of the device includes a base plate 11 and a fixing frame 12 disposed on the upper side of the base plate 11; the dust filter chamber 2 is disposed on the top of the fixing frame 12; the dust collection box 3 is placed on the upper side of the base plate 11 and is detachably connected to the fixing frame 12.

[0027] In this optional embodiment, by placing the dust filter chamber 2 on top of the fixing frame 12 and placing the dust collection box 3 on the base plate 11, the position of the dust filter chamber 2 can be much higher than the position of the dust collection box 3. This facilitates the dust in the dust filter chamber 2 falling into the dust collection box 3 by its own weight, improving dust collection efficiency. Furthermore, by placing the dust collection box 3 on the upper side of the base plate 11 and detachably connecting it to the fixing frame 12, the dust collection box 3 is easy to assemble and disassemble. This allows for two advantages: firstly, when the dust collection box 3 is full, it can be removed from the fixing frame 12 and hoisted to the unloading point for unloading without having to move the entire dust recovery device, improving unloading convenience; secondly, when removing the dust collection box 3, a spare dust collection box 3 can be installed to ensure continuous dust collection, thereby guaranteeing dust collection efficiency.

[0028] Optionally, such as Figure 1 As shown, the electrolytic cell dust recovery device also includes a fastening buckle 5, which includes a first fastener provided on the dust collection box 3 and a second fastener provided on the fixing frame 12. The first fastener and the second fastener are fastened to each other so that the dust collection box 3 and the fixing frame 12 can be detachably connected.

[0029] Specifically, the first fastener may include a hook, and the second fastener may include a rotating plate and a buckle hinged to the rotating plate. As the rotating plate rotates relative to the fixed frame 12, the buckle can engage or disengage with the hook, thereby connecting or separating the dust collection box 3 from the fixed frame 12, thus achieving a detachable connection between the dust collection box 3 and the fixed frame 12.

[0030] In this optional embodiment, when the first fastener and the second fastener are engaged, the dust collection box 3 is connected to the fixing frame 12. When the first fastener and the second fastener are disengaged, the dust collection box 3 is separated from the fixing frame 12, thereby realizing the detachable connection between the dust collection box 3 and the fixing frame 12. The two fasteners have a simple structure and are easy to operate, thereby improving the convenience of assembling and disassembling the dust collection box 3.

[0031] Optionally, such as Figure 3 and Figure 4 As shown, the dust collection box 3 includes a box body 31 and a discharge door 32. The bottom of the box body 31 has an opening, and the discharge door 32 is rotatably mounted on the bottom of the box body 31 for rotating relative to the box body 31 to open or close the opening.

[0032] Specifically, when using this device, the dust-laden air is first filtered by the dust filter chamber 2 to obtain dust, which is then sent into the dust collection box 3 by the discharge pipe 4. When the dust collection box 3 is full of dust, the dust collection box 3 is removed from the fixed frame 12 and then hoisted to a certain height above the unloading point. Then the unloading door 32 can be opened, so that the dust in the box 31 falls to the unloading point by its own weight, thus completing the unloading.

[0033] In this optional embodiment, since the unloading door 32 is installed at the bottom of the box 31, when the unloading door 32 rotates and closes the opening, the dust inside the box 31 can fall off by its own weight without the need for manual shoveling, which can improve the unloading efficiency.

[0034] Optionally, such as Figure 3 and Figure 4 As shown, the dust collection box 3 also includes a lifting lug 34 located on the top of the box body 31. Thus, when the dust collection box 3 needs to be lifted to the unloading point for unloading, the overhead crane can be connected to the lifting lug 34 to achieve rapid lifting of the dust collection box 3.

[0035] Optionally, such as Figure 3 and Figure 5 As shown, the unloading gate 32 is provided with a first locking part 321; the electrolytic cell dust recovery device also includes a rotating rod 6 rotatably installed on the housing 31, and the rotating rod 6 is provided with a second locking part 61. When the unloading gate 32 closes the opening, the rotating rod 6 rotates to make the second locking part 61 cooperate with the first locking part 321, thereby fixing the unloading gate 32 in the closed opening state. When the second locking part 61 is disengaged from the first locking part 321, the unloading gate 32 swings downward under its own weight to open the opening.

[0036] Specifically, the rotating rod 6 can be installed on the lower part of the side wall of the box 31 so as to be offset from the position of the unloading door 32 at the bottom of the box 31. Furthermore, when the rotating rod 6 and the unloading door 32 are respectively located on the side wall and bottom of the box 31, the first locking part 321 can be provided on the circumferential edge of the unloading door 32 so as to be able to contact and cooperate with the second locking part 61 located on the side of the box 31.

[0037] In this optional embodiment, since the unloading gate 32 is provided with a first locking part 321, and the rotating rod 6 is rotatably installed on the housing 31 and is provided with a second locking part 61, when the rotating rod 6 is operated to rotate, the second locking part 61 can be controlled to cooperate or disengage with the first locking part 321, thereby controlling the state of the unloading gate 32 and ultimately opening or closing the opening. This avoids direct operation of the unloading gate 32, thereby increasing the convenience and safety of operation.

[0038] Optionally, such as Figure 5 As shown, the first locking part 321 is configured as a locking pin, and the second locking part 61 is configured as a locking hook.

[0039] In this optional embodiment, by setting the first locking part 321 as a locking post and the second locking part 61 as a locking hook, when the locking hook hooks onto the locking post, the first locking part 321 and the second locking part 61 are engaged. Because the locking hook hooks onto the locking post, a relatively stable engagement state between the locking hook and the locking post can be ensured, and they are not easily separated due to accidents, thereby improving the reliability of the device.

[0040] Optionally, such as Figure 3 and Figure 4 As shown, there are two unloading gates 32. The ends of the two unloading gates 32 that are far apart are hinged to the two opposite edges of the opening. When the two unloading gates 32 are rotated to close, the ends that are close to each other are joined at the middle position of the opening to close the opening.

[0041] It should be noted that when there are two unloading gates 32, each of the two unloading gates 32 can be provided with a first locking part 321. Correspondingly, the rotating rod 6 can be provided with two second locking parts 61, which are used to cooperate with the two first locking parts 321 respectively.

[0042] In this optional embodiment, by setting two unloading doors 32, the two unloading doors 32 can swing open synchronously, which is fast and helps to improve unloading efficiency. In addition, compared with using an integral door panel to open and close the opening, the two unloading doors 32 occupy less vertical space after opening, so that the opening can be as close to the unloading point as possible during unloading, thereby reducing the dust generated.

[0043] Optionally, such as Figure 3 and Figure 4 As shown, the bottom of the unloading gate 32 is provided with a first roller 33.

[0044] In this optional embodiment, the first roller 33 allows the dust collection box 3 to move within the workshop. When the dust collection box 3 needs to be replaced, the movable design allows the spare dust collection box 3 to quickly approach the main body 1 of the device, which helps to reduce the downtime of the device and ensure the efficiency of dust collection.

[0045] Optionally, such as Figure 3 and Figure 5As shown, the electrolytic cell dust recovery device also includes an operating lever 7 rotatably mounted on the housing 31. The operating lever 7 is provided with a sliding groove 71 arranged along its length direction. A limit spring 72 is also connected between the operating lever 7 and the housing 31. One end of the rotating rod 6 is rotatably mounted on the housing 31, and the other end is provided with a connecting post 62. The connecting post 62 is inserted into the sliding groove 71 and can move and rotate in the sliding groove 71.

[0046] Specifically, the control lever 7 is rotatably connected to the housing 31 at approximately the middle position, and the slide groove 71 is opened at the lower end of the control lever 7.

[0047] In this optional embodiment, because the connecting post 62 of the rotating rod 6 is inserted into the slide groove 71 of the operating rod 7 and can move and rotate within the slide groove 71, the operating rod 7 can immediately drive the rotating rod 6 to rotate when it rotates, thereby controlling the state of the unloading gate 32. Using the operating rod 7 allows operators to stay as far away from the unloading gate 32 as possible, thus improving the safety of unloading. In addition, the limiting spring 72 connected between the operating rod 7 and the housing 31 can generate an elastic limiting force on the operating rod 7 when the unloading gate 32 is closed, preventing the operating rod 7 from rotating accidentally, thereby firmly locking the unloading gate 32 and preventing the unloading gate 32 from accidentally opening and causing dust to spill.

[0048] Optionally, such as Figure 5 As shown, the second locking part 61 is close to the hinge end of the rotating rod 6. This allows the distance between the second locking part 61 and the hinge end to be as short as possible, which helps to shorten the lever arm and makes it easier to rotate the rotating rod 6 to open.

[0049] Optionally, such as Figure 3 and Figure 4 As shown, the electrolytic cell dust recovery device also includes a pull rope 73 connected to the control lever 7. Specifically, the pull rope 73 can be connected to the upper end of the control lever 7. In this way, when it is necessary to open the unloading door 32, the control lever 7 can be rotated by pulling the pull rope 73 by hand, without the need to directly operate the control lever 7. This allows the operator to stay further away from the unloading door 32 and further improves the safety of unloading.

[0050] Optionally, such as Figure 1 As shown, the electrolytic cell dust recovery device also includes a dust suction pipe 8, which includes at least two dust suction pipe sections 81 arranged sequentially along its length. Two adjacent dust suction pipe sections 81 are detachably connected by a connector 82. The rear dust suction pipe section 81 is connected to the dust filter chamber 2, and the front dust suction pipe section 81 is used to extend into the electrolytic cell.

[0051] It should be noted that the number of suction pipe sections 81 can be two or more, specifically in... Figure 1In the middle, there are two suction pipe sections 81. The two suction pipe sections 81 are detachably connected by a connector 82. One suction pipe section 81 at the rear end is connected to the dust filter chamber 2, and the other suction pipe section 81 at the front end is used to extend to the electrolytic cell.

[0052] In this optional embodiment, the rear suction pipe section 81 is connected to the dust filter chamber 2, and the front suction pipe section 81 extends to the electrolytic cell. This allows the suction pipe 8 to draw in the dust accumulated at the top of the electrolytic cell and discharge the dust-laden air into the dust filter chamber 2, thus achieving the suction of the dust to be cleaned. Furthermore, it is understood that the longer the suction pipe 8, the greater its internal air resistance, which affects suction efficiency. Therefore, this optional embodiment allows adjacent suction pipe sections 81 to be detachably connected via a connector 82, meaning the entire suction pipe 8 is segmented. This allows the number of suction pipe sections 81 to be adjusted according to the distance between the device and the point to be cleaned, thereby changing the overall length of the suction pipe 8. This ensures that the length of the suction pipe 8 is adapted to the distance between the device and the point to be cleaned, preventing the suction pipe 8 from being too long and affecting suction efficiency.

[0053] Optionally, such as Figure 1 As shown, the vacuuming pipe 8 also includes an inlet pipe section 83, which is connected to the front vacuuming pipe section 81, and the cross-section gradually decreases along the direction from the rear end to the front end of the vacuuming pipe 8.

[0054] In this optional embodiment, by gradually reducing the cross-section of the inlet pipe section 83 along the direction from the rear end to the front end of the suction pipe 8, the inlet pipe section 83 is made into a flat nozzle shape. This allows the suction force at the front end of the suction pipe 8 to be concentrated in a narrow area, making the airflow more concentrated and the suction force stronger, thereby effectively removing dust and improving the dust collection efficiency.

[0055] Optionally, such as Figure 1 As shown, the dust filtration chamber 2 has a filter element 21 in its inner cavity, which divides the inner cavity of the dust filtration chamber 2 into an upper chamber and a lower chamber; the dust suction pipe 8 and the dust collection box 3 are both connected to the lower chamber; the electrolytic cell dust recovery device also includes an exhaust fan 91 and a blower, the exhaust fan 91 is connected to the upper chamber through an exhaust pipe 92, and the blower is connected to the upper chamber through a backflush pipe 93.

[0056] Specifically, filter element 21 can be a bag filter element. The exhaust fan 91 can be a vortex fan located in the main body 1 to extract air from the dust filter chamber 2, and the blowing fan can be an air compressor located in the main body 1 to blow gas into the dust filter chamber 2. Additionally, the upper end of the exhaust pipe 92 can be connected to the upper chamber, and the lower end can be connected to the exhaust fan 91; the upper end of the backflush pipe 93 can be connected to the upper chamber, and the lower end can be connected to the blowing fan. Furthermore, an exhaust pipe 94 can be connected to the exhaust fan 91, through which the exhaust fan 91 can discharge the extracted air to the outside.

[0057] In this optional embodiment, both the suction pipe 8 and the dust collection box 3 are connected to the lower chamber, and the exhaust fan 91 is connected to the upper chamber through the exhaust pipe 92. Thus, after the exhaust fan 91 is started, alumina dust will be sucked into the lower chamber by the suction pipe 8. The dust-laden air will continue to flow upward and pass through the filter element 21. After passing through the filter element 21, the dust will be filtered and fall to the bottom of the lower chamber, and finally discharged into the dust collection box 3 through the discharge pipe 4 for collection. The air will pass through the filter element 21 and enter the upper chamber, and finally flow into the exhaust fan 91 through the exhaust pipe 92, thereby completing the dust suction. Meanwhile, it is understandable that the filter element 21 plays the role of filtering dust, but over time, the pores of the filter element 21 are easily blocked, thus affecting the dust collection efficiency. Therefore, in this optional embodiment, by adding an air blower and a back-blowing pipe 93, and the air blower is connected to the upper chamber through the back-blowing pipe 93, when the filter element 21 is blocked, the air blower can be started. After the air blower is started, it can blow gas into the upper chamber through the back-blowing pipe 93. After the gas enters the upper chamber, it can blow downward to clean the dust on the filter element 21, thereby ensuring the unobstructed pores of the filter element 21 and thus ensuring the dust collection efficiency.

[0058] Optionally, such as Figure 1 As shown, the cross-section of the dust filter chamber 2 near its lower end gradually narrows downwards, making the lower part of the dust filter chamber 2 roughly conical, facilitating the downward sliding of dust. Simultaneously, a discharge valve 22 can be installed at the connection point between the bottom of the dust filter chamber 2 and the discharge pipe 4, allowing for the start or stop of discharge by controlling the opening and closing of the discharge valve 22. Furthermore, a backflush pulse valve 931 can be installed on the backflush pipe 93, allowing for the timed opening of the backflush pulse valve 931 to achieve timed air jet cleaning of the filter element 21 within the backflush pipe 93, effectively ensuring the unobstructed flow of air through the pores of the filter element 21.

[0059] like Figure 1As shown, the electrolytic cell dust recovery device may also include an electrical control box 10. The electrical control box 10 is electrically connected to the exhaust fan 91, the discharge valve 22, and the back-flushing pulse valve 931, respectively. Thus, the electrical control box 10 can control the exhaust fan 91, the discharge valve 22, and the back-flushing pulse valve 931 according to a set program, achieving automated dust collection, discharge, and back-flushing. Furthermore, the circuit of the electrical control box 10 may be equipped with a phase sequence protector, which can effectively prevent the exhaust fan 91 from reversing or being damaged due to reversed power line phase sequence, thereby improving the safety of the device operation.

[0060] It should be noted that currently, the movement of the equipment within the aluminum electrolysis workshop often requires operators to walk, which increases their physical exertion. Therefore, alternatively, such as... Figure 2 As shown, the main body 1 of the device may also include a second roller 13, a third roller 14, a steering handle 15, a power system, and a seat 16. The second roller 13 and the third roller 14 are located at the bottom of the base plate 11 and are used to drive the main body 1 of the device to move. The steering handle 15, the power system, and the seat 16 are located on the upper side of the base plate 11. The steering handle 15 is used to control the steering of the third roller 14. The power system is driven by the third roller 14 to control the rotation of the third roller 14. In this way, the operator can control the movement of the device by sitting on the seat 16 and operating the steering handle 15, without the need for the operator to walk to control it, thereby reducing the physical exertion of the operator.

[0061] When this electrolytic cell dust recovery device is in operation, the exhaust fan 91 is started first. The alumina dust at the dust collection point is then sucked into the dust filter chamber 2 by the dust collection pipe 8. After entering the dust filter chamber 2, the dust is filtered and discharged into the dust collection box 3 through the discharge pipe 4 for collection. After the dust collection box 3 is full of dust, it is removed from the fixing frame 12 and then hoisted to a certain height above the unloading point. Then, the unloading door 32 can be opened, allowing the dust in the box 31 to fall to the unloading point by its own weight, thus completing the unloading. When the pores of the filter element 21 of the dust collection box 3 become clogged due to long-term use, the blowing fan is started first. After the blowing fan is started, back-blowing gas is blown into the filter element 21 through the back-blowing pipe 93, thereby blowing away the dust clogging the pores of the filter element 21, thus completing the cleaning of the filter element 21 and facilitating subsequent dust filtration.

[0062] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
