Description

Technical Field

[0001] This utility model relates to the field of electrolytic cell technology, and more specifically, to an electrolytic cell feeding device. Background Technology

[0002] During the operation of aluminum electrolysis cells, it is often necessary to add insulating material to cover the anode carbon blocks to maintain the energy balance of the aluminum electrolysis cell. In related technologies, the insulating material is usually transported by wheelbarrows or hoppers. However, when the wheelbarrows or hoppers arrive at the location where the insulating material needs to be added, it is often necessary to manually shovel or pour the insulating material into the electrolysis cell, which involves a large amount of manual labor and low material addition efficiency.

[0010] Optionally, the bottom wall of the box body gradually slopes upwards in the direction away from the discharge port.

[0011] Optionally, the support frame includes a plurality of support columns, and the support column closest to the operating lever among the plurality of support columns is a limiting support column, which is used to abut against the operating lever when the connecting rod is in the locked state, so as to restrict the movement of the operating lever.

[0012] Optionally, a stop rod is connected to the end of the connecting rod away from the baffle; the electrolytic cell feeding device further includes a limiting mechanism, the limiting mechanism including a limiting rod, the limiting rod being movably installed on the housing, and when the limiting rod moves to the stop position, the movement paths of the limiting rod and the stop rod intersect to restrict the connecting rod from switching between the locked state and the unlocked state.

[0014] Optionally, the upper end of the box is open to form a feeding port, and a plurality of lifting lugs are arranged sequentially along the edge of the feeding port.

[0015] The beneficial effects of the electrolytic cell feeding device of this utility model are as follows: By providing a discharge port on the box body and rotatably installing a baffle on the box body, the baffle can open and close the discharge port by rotating.

[0022] This utility model provides an electrolytic cell feeding device, which can improve the efficiency of adding heat-insulating material to the electrolytic cell and ensure ease of operation. The following is a detailed description with reference to specific embodiments.

[0023] like Figure 1 and Figure 2As shown in the figure, an electrolytic cell feeding device provided by this utility model embodiment includes a housing 1, a baffle 2, and a locking mechanism 3. The housing 1 is provided with a discharge port 111. The baffle 2 is rotatably mounted on the housing 1 and has a closed position for closing the discharge port 111 and an open position for opening the discharge port 111. The baffle 2 is provided with a locking part 21. The locking mechanism 3 includes a connecting rod 31. The middle part of the connecting rod 31 is rotatably mounted on the housing 1 and its rotation axis is perpendicular to the connecting rod 31. The end of the connecting rod 31 near the baffle 2 is provided with a mating part 311. When the connecting rod 31 is rotated to the locked state, the mating part 311 and the locking part 21 cooperate to fix the baffle 2 in the closed position. When the connecting rod 31 is rotated to the unlocked state, the mating part 311 and the locking part 21 are disengaged so that the baffle 2 can rotate from the closed position to the open position.

[0024] Specifically, when using this electrolytic cell feeding device, the baffle 2 can be rotated to the closed position first, and then the connecting rod 31 can be rotated to the locked state (see...). Figure 2 This allows the mating part 311 to engage with the locking part 21, fixing the baffle 2 in the closed position and ensuring that the baffle 2 stably closes the discharge port 111. At this time, insulation material can be added into the housing 1. Then, the electrolytic cell feeding device is transported to the location of the insulation material to be added to the electrolytic cell. By rotating the connecting rod 31 to the unlocked state, the mating part 311 and the locking part 21 are disengaged. At this time, the baffle 2 can be pushed open under the gravity of the insulation material, that is, it can be rotated from the closed position to the open position, thereby opening the discharge port 111 (see...). Figure 1 Finally, the insulation material automatically flows out from box 1 and is added to the electrolytic cell.

[0025] In this embodiment, by providing a discharge port 111 on the housing 1 and rotatably mounting a baffle 2 on the housing 1, the baffle 2 can open and close the discharge port 111 by rotating. This allows the baffle 2 to automatically rotate under the weight of the insulation material when not constrained by the locking mechanism 3, thus opening the discharge port 111 and facilitating the automatic flow of the insulation material into the electrolytic cell. This eliminates the need for manual shoveling or emptying of the insulation material, reducing manual labor and improving the efficiency of adding insulation material to the electrolytic cell. Furthermore, by setting the locking mechanism 3 as a connecting rod 31… The middle part of the connecting rod 31 is rotatably mounted on the housing 1 and its rotation axis is perpendicular to the connecting rod 31. At the same time, the end of the connecting rod 31 near the baffle 2 is provided with a mating part 311. In this way, when force is applied to the end of the connecting rod 31 away from the baffle 2, the connecting rod 31 can rotate immediately, causing the end of the connecting rod 31 near the baffle 2 to move, so that the mating part 311 can engage or disengage with the locking part 21, ultimately locking or unlocking the baffle 2. This ensures that the point of force application on the connecting rod 31 is relatively far away from the baffle 2, ensuring convenient operation.

[0026] Optionally, such as Figure 1As shown, the upper end of the box 1 is open to form a feeding port 112, and a plurality of lifting lugs 113 are arranged sequentially along the edge of the feeding port 112.

[0027] In this optional embodiment, the upper end of the box 1 is opened to form a feeding port 112, so as to add insulation material into the box 1. The multiple lifting lugs 113 on the edge of the feeding port 112 can be connected to cables, so that the crane can hook the cables and quickly lift the electrolytic cell feeding device to the place where the insulation material is to be added in the electrolytic cell.

[0028] Optionally, such as Figure 1 As shown, the locking part 21 includes a locking rod 211 extending along the rotation axis of the baffle 2; the mating part 311 includes a hook-stop post 3111 extending radially along the connecting rod 31. When the connecting rod 31 is rotated to the locked state, the locking rod 211 is limited between the connecting rod 31 and the hook-stop post 3111.

[0029] Specifically, such as Figure 1 As shown, the baffle 2 is connected to the side wall of the housing 1 via a hinge 22, and the locking rod 211 extends along the axis of the hinge 22, specifically horizontally. Additionally, the connecting rod 31 can be located on one side of the housing 1, and the hook-stop post 3111 extends radially downward from the side wall of the connecting rod 31. The end of the locking rod 211 can extend to the side of the housing 1 where the connecting rod 31 is located, so that it can be hooked by the hook-stop post 3111 located on the connecting rod 31, thus achieving the engagement of the mating part 311 and the locking part 21. Furthermore, placing the connecting rod 31 on one side of the housing 1 avoids the connecting rod 31 occupying too much space below the housing 1. At this time, as... Figure 2 As shown, the hook-stop column 3111 can hook the locking rod 211 from above and downwards. This can prevent the connecting rod 31 from occupying too much space under the box 1 during rotation. When the hook-stop column 3111 and the locking rod 211 are engaged, the hook-stop column 3111 is in a forward and downward tilted state, while the locking rod 211 is in front of the hook-stop column 3111 (positive X-axis direction) and is limited between the connecting rod 31 and the hook-stop column 3111. Thus, the locking rod 211 will be blocked by the hook-stop column 3111 and cannot move backwards, thereby preventing the baffle 2 from rotating and keeping the discharge port 111 closed.

[0030] In this optional embodiment, by setting the locking part 21 as a locking rod 211 extending along the rotation axis of the baffle 2, and setting the mating part 311 as a hook-stop post 3111 extending radially along the connecting rod 31, the mating part 311 and the locking part 21 can be mated when the hook-stop post 3111 hooks onto the side of the locking rod 211 away from the middle of the connecting rod 31. This results in a simple structure that is easy to use. At the same time, the locking rod 211 extends along the rotation axis of the baffle 2, and the length of the locking rod 211 can be slightly greater than the length of the baffle 2, thereby improving the structural strength of the baffle 2, making the baffle 2 less prone to deformation, and reliably sealing the discharge port 111 to prevent material leakage.

[0031] Optionally, such as Figure 2 and Figure 3 As shown, a guide surface 3112 is provided at the connection between the side and end face of the hook post 3111, and the guide surface 3112 surrounds the hook post 3111.

[0032] Specifically, the guide surface 3112 can be formed by machining fillets or chamfers at the connection between the side surface and the end surface.

[0033] In this optional embodiment, the guide surface 3112 can eliminate the sharp edge of the hook post 3111, thereby helping to guide the hook post 3111 to the side of the locking rod 211 away from the middle of the connecting rod 31, making the engagement process of the mating part 311 and the locking part 21 easier.

[0034] Optionally, such as Figure 1 As shown, the upper end of the baffle 2 is hinged to the upper edge of the discharge port 111, and the lower end is provided with the locking rod 211.

[0035] Specifically, the upper end of the baffle 2 is hinged to the upper edge of the discharge port 111 via hinge 22.

[0036] In this optional embodiment, when the locking rod 211 is hooked by the hooking post 3111, because the locking rod 211 is at the lower end of the baffle 2, and the upper end of the baffle 2 is hinged to the upper edge of the discharge port 111, both the upper and lower ends of the baffle 2 can remain fixed relative to the discharge port 111, thereby improving the reliability of the baffle 2 in closing the discharge port 111. In addition, since the upper end of the baffle 2 is hinged to the box body 1, the discharge port 111 can be opened by flipping the lower end of the baffle 2 upward, and only a small angle of flipping is required to achieve unloading, thereby facilitating the automatic insulation material to automatically push the baffle 2 and flow out of the box body 1 under the action of gravity.

[0037] Optionally, such as Figure 2 As shown, the end of the connecting rod 31 away from the baffle 2 is connected to an operating rod 32, which extends along the rotation axis of the connecting rod 31.

[0038] It should be noted that the operating lever 32 can be indirectly connected to the connecting rod 31, such as... Figure 2 As shown, the locking mechanism 3 also includes a connecting rod 33 and a stop rod 34 as described below. The stop rod 34 is connected to the connecting rod 31, the connecting rod 33 is connected to the stop rod 34, and the operating rod 32 is connected to the connecting rod 33. Thus, the operating rod 32 is indirectly connected to the connecting rod 31 via the connecting rod 33 and the stop rod 34. Additionally, it should be noted that... Figure 2 As shown, the locking mechanism 3 may include two connected links 31. The two links 31 can be connected to the two ends of the stop rod 34 respectively to achieve interconnection. The two links 31 are located on both sides of the housing 1. Each link 31 is provided with a hooking post 3111. The hooking posts 3111 of the two links 31 are used to hook the two ends of the locking rod 211 at the same time to ensure the hooking effect.

[0039] In this optional embodiment, by connecting an operating lever 32 to the end of the connecting rod 31 away from the baffle 2, and the operating lever 32 extending along the rotation axis of the connecting rod 31, it is easier for the operator to apply force, thereby making it easier to push the connecting rod 31 to rotate.

[0040] Optionally, such as Figure 1 As shown, the box 1 includes a box body 11 and a support frame 12 located at the lower end of the box body 11. The discharge port 111 is located on the lower part of the side wall of the box body 11. The middle part of the connecting rod 31 is rotatably mounted on the support frame 12 and its rotation axis is parallel to the rotation axis of the baffle 2. The operating lever 32 is located on the side of the support frame 12 away from the discharge port 111.

[0041] Specifically, the discharge port 111 can be located on the lower part of the rear side wall of the box body 11. Additionally, in conjunction with... Figure 2 and Figure 4 The support frame 12 can be fitted with a bushing 121, and a connecting shaft 35 can be connected to the middle of the connecting rod 31. The connecting shaft 35 and the bushing 121 are rotatably engaged, so that the middle of the connecting rod 31 is rotatably mounted on the support frame 12. Of course, it should be noted that, in addition to opening the discharge port 111 on the lower side wall of the box body 11, in some other embodiments, the discharge port 111 can also be opened on the bottom wall of the box body 11.

[0042] The operating lever 32 is located at the end of the connecting rod 31 away from the baffle 2, specifically on the side of the support frame 12 away from the discharge port 111. This allows the operating lever 32 to be far from the end of the connecting rod 31 with the mating part 311, and also allows the operating lever 32 to be located on the outside of the support frame 12. This makes the driving operation of the connecting rod 31 less strenuous and avoids interference between the operator's hand and the support frame 12 during operation. It also eliminates the need for the operator to reach into the support frame 12 to operate, thus improving the convenience of operation.

[0043] In this optional embodiment, the box body 11 is used to hold the insulation material. The support frame 12 is located below the box body 11 and can thus support the box body 11. When the insulation material is added to the box body 11, the box body 11 can be supported on the ground by the support frame 12 to improve stability and facilitate the addition of insulation material. Furthermore, since the baffle 2 is close to the lower part of the side wall of the box body 11 and the locking rod 211 is close to the bottom wall of the box body 11, the connecting rod 31, which is used to lock and cooperate with the locking rod 211, is also close to the bottom wall of the box body 11. Moreover, since the rotation axis of the connecting rod 31 is parallel to the rotation axis of the baffle 2, that is, the connecting rod 31 rotates up and down, the movement of the connecting rod 31 requires a certain vertical space. In this embodiment, by setting the support frame 12 at the lower end of the box body 11, the support frame 12 can support and form a certain operating space between the bottom of the box body 11 and the ground to facilitate the rotation operation of the connecting rod 31.

[0044] Optionally, such as Figure 2 As shown, the bottom wall of the box body 11 gradually slopes upwards in the direction away from the discharge port 111.

[0045] In this optional embodiment, by gradually tilting the bottom wall of the box body 11 upwards in the direction away from the discharge port 111, on the one hand, the insulation material inside the box body 11 can be pushed open by gravity and fall quickly down along the bottom wall, which can improve the efficiency and completeness of unloading; on the other hand, the lower part of the box body 11 can form a space for the support frame 12 and the locking mechanism 3 to be installed, without significantly increasing the overall height of the box body 1. For example, the box body 11 and the support frame 12 can roughly form a cuboid structure without excessively increasing the height of the box body.

[0046] Optionally, such as Figure 2 As shown, the support frame 12 includes a plurality of support columns 122. The support column 122 closest to the operating lever 32 is a limiting support column. The limiting support column is used to abut against the operating lever 32 when the connecting rod 31 is in the locked state, so as to restrict the movement of the operating lever 32.

[0047] It should be noted that, as Figure 2 As shown, the two foremost (positive X-axis) support columns 122 are the support columns closest to the operating lever 32, i.e., the limit support columns, and... Figure 2 The connecting rod 31 is in the locked state, at which time the limiting support column abuts against the end of the operating rod 32 near the baffle 2. It should also be noted that the operating rod 32 has an upper intersection point with the limiting support column along its movement path with the connecting rod 31. Figure 2 Status lever 32 is at the upper intersection and lower intersection. Figure 4When the operating lever 32 is at the lower intersection point, and the operating lever 32 is at the upper or lower intersection point, its end near the baffle 2 abuts against the limiting support column. The phrase "the limiting support column is used to abut against the operating lever 32 when the connecting rod 31 is in the locked state" means that the operating lever 32 is exactly at the upper intersection point when the connecting rod 31 is in the locked state. Specifically, as... Figure 4 As shown, the support frame 12 may also include a base plate 123, with multiple support columns 122 disposed on the base plate 123, and the box body 11 disposed on the upper end of the multiple support columns 122.

[0048] In this optional embodiment, the multiple support columns 122 can provide multi-point support for the box body 11, which helps to further improve the stability of the box body 11. In addition, the limiting support column can abut against the operating rod 32 when the connecting rod 31 is in the locked state, so as to restrict the movement of the operating rod 32. This can prevent the end of the connecting rod 31 where the mating part 311 is located from continuing to squeeze the locking part 21, causing the connecting rod 31 and the locking part 21 to bend and deform. Over time, this will affect the reliability of the baffle 2 in closing the discharge port 111.

[0049] Furthermore, such as Figure 4 As shown, the lower intersection point of the operating lever 32 with the limit support column along the movement path of the connecting rod 31 and the base plate 123 is spaced apart. This ensures that when the operating lever 32 is at its lowest point, there is a certain distance between its lower end and the base plate 123, preventing the operator from pinching their hand when the operating lever 32 is moved to the lowest point.

[0050] Optionally, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the end of the connecting rod 31 away from the baffle 2 is connected to a stop rod 34; the electrolytic cell feeding device also includes a limiting mechanism 4, which includes a limiting rod 41. The limiting rod 41 is movably installed on the housing 1. When the limiting rod 41 moves to the stop position, the movement paths of the limiting rod 41 and the stop rod 34 intersect, thereby restricting the connecting rod 31 from switching between the locked state and the unlocked state.

[0051] Specifically, the stop rod 34 can extend along the rotation axis of the connecting rod 31. Additionally, the limiting rod 41 can be reciprocated in a direction toward or away from the baffle 2 and is mounted on the housing 1 (specifically, on the support frame 12), for example... Figure 1 As shown, a mounting sleeve 124 extending toward the baffle 2 is provided on the support frame 12. The limiting rod 41 is inserted into the mounting sleeve 124 and can reciprocate relative to the mounting sleeve 124 in the direction toward or away from the baffle 2, so that the limiting rod 41 can be reciprocated and installed on the box 1.

[0052] It should be noted that the movement path of the stop lever 34 refers to the arc-shaped path formed by the stop lever 34 as the link 31 moves along with the link 31 when switching between the locked and unlocked states. It can be understood that when the movement paths of the limit lever 41 and the stop lever 34 intersect, for example, when the link 31 is in the locked state, such as... Figure 2 As shown, the limiting rod 41 at the stop position is located below the stop rod 34. The stop rod 34 is hindered by the limiting rod 41 and is difficult to move downward, thus restricting the linkage 31 from switching from the locked state to the unlocked state. This allows the linkage 31 to be fixed in the locked state. For example, when the linkage 31 is in the unlocked state, such as... Figure 1 As shown, the limiting rod 41 at the stop position is located above the stop rod 34. The stop rod 34 is restricted from moving upward by the limiting rod 41, which in turn restricts the linkage 31 from switching from the unlocked state to the locked state, thereby fixing the linkage 31 in the unlocked state.

[0053] In this optional embodiment, the limiting rod 41 can be moved to reach the stop position. When the limiting rod 41 is in the stop position, the limiting rod 41 and the stop rod 34 intersect along the movement path of the connecting rod 31, thereby restricting the connecting rod 31 from switching between the locked state and the unlocked state. This can prevent the connecting rod 31 in the locked state from accidentally disengaging from the locked state, so as to ensure the stable locking of the baffle 2. It can also prevent the connecting rod 31 in the unlocked state from accidentally disengaging from the unlocked state, so as to avoid the connecting rod 31 rotating and interfering with the locking part 21, affecting the normal discharge of the insulation material. It can also ensure that the operator does not need to hold the operating rod 32 all the time, reducing the amount of manual labor.

[0054] Optionally, such as Figure 5 and Figure 6 As shown, the housing 1 is provided with a positioning slot 125; the limiting mechanism 4 also includes a positioning rod 42 that is cross-connected with the limiting rod 41. The limiting rod 41 can rotate relative to the housing 1 around its own axis so that the positioning rod 42 can be engaged or disengaged from the positioning slot 125. When the positioning rod 42 is engaged in the positioning slot 125, it is used to position the limiting rod 41 at the stop position.

[0055] Specifically, the positioning slot 125 can be set on the support frame 12 of the housing 1. In addition, the limiting rod 41 can be installed on the support frame 12 through the mounting sleeve 124, so that the limiting rod 41 can simultaneously move along its axis and rotate around its axis relative to the support frame 12. Therefore, when it is necessary to insert the positioning rod 42 into the positioning slot 125, the limiting rod 41 can be moved first to align the positioning rod 42 with the positioning slot 125, and then the limiting rod 41 can be rotated to make the positioning rod 42 engage in the positioning slot 125, thereby restricting the movement of the limiting rod 41. At this time, the limiting rod 41 is positioned at the stop position. When the limiting rod 41 is rotated to make the positioning rod 42 disengage from the positioning slot 125, the movement restriction of the limiting rod 41 can be released, so that the limiting rod 41 can move and leave the stop position.

[0056] In this optional embodiment, by providing a positioning slot 125, a positioning rod 42 can be inserted to position the limiting rod 41 at the stop position, thereby ensuring a stable stopping effect on the stop rod 34.

[0057] Furthermore, such as Figure 5 and Figure 6 As shown, the housing 1 can also be provided with an avoidance slot 126. The avoidance slot 126 is located on the side of the positioning slot 125 away from the baffle 2. When the limiting rod 41 moves from the stop position away from the baffle 2 to a position where it does not intersect with the movement path of the stop rod 34, the positioning rod 42 can be engaged in the avoidance slot 126 (achieved by rotating the limiting rod 41) to position the limiting rod 41 at that position. At this time, the stop rod 34 can move normally. Both the positioning slot 125 and the avoidance slot 126 can be provided on the support frame 12 of the housing 1. Specifically, the support frame 12 is provided with three positioning blocks 127. The three positioning blocks 127 are arranged sequentially at intervals along the direction towards the baffle 2. The intervals between the three positioning blocks 127 correspond to the positioning slot 125 and the avoidance slot 126.

[0058] 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.
