Description

Technical Field

[0001] This utility model relates to the field of electrolytic aluminum cleaning technology, and in particular to a cleaning structure for electrolytic aluminum electrolytic cells. Background Technology

[0002] Electrolytic aluminum is aluminum obtained through electrolysis. Modern industrial production of electrolytic aluminum uses the cryolite-alumina molten salt electrolysis method. Molten cryolite is used as the solvent, alumina as the solute, carbonaceous material as the anode, and molten aluminum as the cathode. When a strong direct current is applied, an electrochemical reaction takes place at the two electrodes in the electrolytic cell.

[0003] Under current conditions, due to the poor solubility of alumina, sludge easily forms at the bottom of the electrolytic cell, and crust easily forms on the sidewalls. Currently, an electrolytic cell cleaning device for aluminum electrolysis, as disclosed in CN219991754U, is used. This device uses a trolley to move the entire device next to the electrolytic cell to be cleaned. One end of an elastic corrugated pipe is then inserted into the electrolytic cell. Under the action of a pump, the electrolyte inside the electrolytic cell is introduced into a fixed box through the elastic corrugated pipe and a first connecting pipe, and then into a collection box through a second connecting pipe for collection. However, this device mainly recovers the electrolyte remaining in the electrolytic cell to facilitate cleaning. A large amount of solid matter accumulates inside the electrolytic cell, especially at the bottom, and some even solidify into clumps. A single adsorption structure is insufficient to remove these solids from the electrolytic cell, and it is difficult to place the cleaning structure in the limited space of the electrolytic cell. This not only affects the cleaning operation but also easily leads to damage or malfunction of the cleaning structure due to collisions or tipping. Utility Model Content

[0004] The purpose of this invention is to solve the problem of difficulty in wiping and cleaning electrolytic cells in the prior art, and to propose a cleaning structure for electrolytic aluminum electrolytic cells.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electrolytic aluminum cell cleaning structure includes a load-bearing bracket mounted on the electrolytic cell. Extension rods are integrally connected to both sides of the load-bearing bracket, and the extension rods are equipped with support mechanisms for supporting the load-bearing bracket on the side wall of the electrolytic cell. A lifting rod is slidably mounted on the load-bearing bracket, and a traction mechanism for driving the lifting rod to move vertically is provided on the load-bearing bracket. A T-shaped frame is slidably mounted on the lifting rod, and a purification mechanism for driving the T-shaped frame to move back and forth is provided on the lifting rod. A wiping brush for cleaning the bottom of the electrolytic cell is mounted on the lower end of the T-shaped frame via a pin, and a storage mechanism for adjusting the opening and closing of the wiping brush is provided on the T-shaped frame.

[0007] Preferably, the support mechanism includes a right-angle plate integrally connected to the extension rod, a telescopic pulley slidably mounted in the right-angle plate and located in the extension rod and vertically abutting the side wall of the electrolytic cell, a swing arm rotatably mounted on the right-angle plate, a first connecting rod pin connecting the telescopic pulley and the swing arm, and a ball bearing movably mounted in the swing arm and horizontally abutting the side wall of the electrolytic cell.

[0008] Preferably, the traction mechanism includes a drive gear rotatably mounted on a load-bearing bracket, two sliders slidably mounted on the load-bearing bracket, and a driven rack that meshes with the drive gear integrally connected to each of the two sliders. A second connecting rod is pin-connected between the driven rack and the lifting rod.

[0009] Preferably, the two driven racks are arranged symmetrically at the center.

[0010] Preferably, the purification mechanism includes a traction turntable rotatably mounted on a lifting rod, and a deflecting swing arm rotatably mounted on the lifting rod, which is movably pulled by the traction turntable and used for movably pulling the T-shaped frame.

[0011] Preferably, the traction turntable is integrally connected with an eccentrically arranged first traction bolt, the deflection swing arm has a first traction long hole for slidingly fitting the first traction bolt at its middle end, the deflection swing arm has a second traction long hole at its lower end, and the T-shaped frame is integrally connected with a second traction bolt that is slidably fitted into the second traction long hole.

[0012] Preferably, the storage mechanism includes a guide elongated hole opened in the T-shaped frame, a lifting block is slidably fitted in the guide elongated hole, and a third connecting rod is pin-connected between the lifting block and the board eraser.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This utility model provides movable or fixed support for the load-bearing bracket and the plate by setting a load-bearing bracket on the electrolytic cell and setting two sets of support mechanisms on the extension rod of the load-bearing bracket. The first cylinder drives the telescopic pulley to make vertical contact with the side wall of the electrolytic cell, while the ball bearing on the opening and closing swing rod makes horizontal contact with the side wall of the electrolytic cell, thereby providing movable or fixed support for the load-bearing bracket and the plate.

[0015] 2. This utility model features a lifting rod on a load-bearing support, driven by a traction mechanism to achieve vertical lifting and lowering; a T-shaped frame on the lifting rod, driven by a purification mechanism to achieve reciprocating movement; and a plate wiper on the T-shaped frame, driven by a storage mechanism to achieve opening and closing adjustment. This allows for flexible adjustment of the plate wiper structure within the electrolytic cell, facilitating the wiping and cleaning of the bottom of the electrolytic cell.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A cleaning structure for an electrolytic aluminum cell includes a load-bearing bracket 1 mounted on the electrolytic cell. Extension rods 2 are integrally connected to both sides of the load-bearing bracket 1, and support mechanisms 3 are provided on the extension rods 2 for supporting the load-bearing bracket 1 on the sidewall of the electrolytic cell. See the attached instruction manual for details. Figure 2 With appendix Figure 3It should be noted that the support mechanism 3 includes a right-angle plate 31 integrally connected to the extension rod 2. A telescopic pulley 32 is slidably installed in the right-angle plate 31, located in the extension rod 2 and vertically abutting the side wall of the electrolytic cell. A swing arm 33 is rotatably installed on the right-angle plate 31. A first connecting rod 34 is pin-connected between the telescopic pulley 32 and the swing arm 33. A ball bearing 35 is movably fitted in the swing arm 33, horizontally abutting the side wall of the electrolytic cell. A first cylinder for pulling the telescopic pulley 32 is fixedly installed in the extension rod 2, so that the telescopic pulley 32 can be extended and retracted according to the side wall of the electrolytic cell. At the same time, the ball bearing 35 in the swing arm 33 can abut against the inner wall of the electrolytic cell. This can ensure that the load-bearing bracket 1 can be displaced and adjusted along the side wall of the electrolytic cell, and can also be fixed in position according to cleaning needs, thereby allowing for segmented treatment of the bottom of the electrolytic cell.

[0024] A lifting rod 4 is slidably mounted on the load-bearing bracket 1, and a traction mechanism 5 for driving the lifting rod 4 to move vertically is provided on the load-bearing bracket 1. See the attached instruction manual for details. Figure 1 The traction mechanism 5 includes a drive gear 51 rotatably mounted on the load-bearing bracket 1. Two sliders 52 are slidably mounted on the load-bearing bracket 1. Each slider 52 is integrally connected with a driven rack 53 that meshes with the drive gear 51. A second connecting rod 54 is pin-connected between the driven rack 53 and the lifting rod 4. A first motor is provided on the load-bearing bracket 1. By adjusting the distance between the two driven racks 53, the lifting rod 4 is tractioned, so that the lifting rod 4 can be adjusted in height by driving the plate 8 through the T-shaped frame 6.

[0025] A T-shaped frame 6 is slidably mounted on the lifting rod 4, and a purification mechanism 7 is provided on the lifting rod 4 to drive the T-shaped frame 6 to move back and forth. See the attached instruction manual for details. Figure 4 The purification mechanism 7 includes a traction turntable 71 rotatably mounted on the lifting rod 4, and a deflection swing rod 73 rotatably mounted on the lifting rod 4, which is movably pulled by the traction turntable 71 and used to move the T-shaped frame 6. By converting the rotational motion of the traction turntable 71 into the linear reciprocating movement of the T-shaped frame 6, the plate wiper 8 moves linearly and reciprocally along the electrolytic cell under the traction of the T-shaped frame 6, thereby repeatedly wiping the bottom of the electrolytic cell.

[0026] The lower end of the T-shaped frame 6 is fitted with a plate eraser 8 for wiping the bottom of the electrolytic cell, and the T-shaped frame 6 is equipped with a storage mechanism 9 for adjusting the opening and closing of the plate eraser 8. See the instruction manual for details. Figure 4 The storage mechanism 9 includes a guide hole 91 opened in the T-shaped frame 6. A lifting block 92 is slidably fitted in the guide hole 91. A third connecting rod 93 is pin-connected between the lifting block 92 and the plate eraser 8. By adjusting the opening and closing angle of the plate eraser 8, the plate eraser 8 can enter the electrolytic cell in the closed state and unfold in the working state, increasing the contact area with the bottom of the electrolytic cell.

[0027] Two driven racks 53 are arranged symmetrically at the center, and under the driving action of the drive gear 51, the two driven racks 53 move towards each other or in opposite directions.

[0028] Please refer to the instruction manual for details. Figure 4 The traction turntable 71 is integrally connected with an eccentrically set first traction bolt 72. The deflection swing rod 73 has a first traction long hole 74 at the middle end that slides and fits the first traction bolt 72. The deflection swing rod 73 has a second traction long hole 75 at the lower end. The T-shaped frame 6 is integrally connected with a second traction bolt 76 that slides and fits in the second traction long hole 75. The rotating traction turntable 71 drives the deflection swing rod 73 to perform a pendulum-like motion, thereby pulling the T-shaped frame 6 to perform a linear reciprocating movement in the horizontal direction.

[0029] It should be noted that the specific models and specifications of the first motor, the second motor, the first cylinder, and the second cylinder need to be selected and determined based on the actual specifications of the device. The specific selection and calculation methods use existing technology in this field, so they will not be elaborated here.

[0030] The functional principle of this utility model can be explained through the following operation methods:

[0031] The load-bearing bracket 1 is placed on the electrolytic cell by the support mechanism 3;

[0032] The control cylinder opens, causing the telescopic pulley 32 to make vertical contact with the side wall of the electrolytic cell. The telescopic pulley 32 supports the opening and closing swing arm 33 to deflect through the first connecting rod 34, causing the ball 35 to make horizontal contact with the side wall of the electrolytic cell.

[0033] The first motor is turned on by controlling the load-bearing bracket 1, and the drive gear 51 moves towards each other through the driven rack 53, which in turn drives the lifting rod 4 to move vertically downward through the second connecting rod 54.

[0034] The second cylinder is opened by controlling the T-shaped frame 6, and the lifting block 92 pulls the plate eraser 8 to deflect through the third connecting rod 93, so that the plate eraser 8 abuts against the bottom of the electrolytic cell;

[0035] The second motor is activated by controlling the lifting rod 4, which causes the traction turntable 71 to rotate. The traction turntable 71 drives the deflection swing rod 73 to deflect, thereby causing the T-shaped frame 6 to move linearly back to the reset position, so that the plate wiper 8 repeatedly wipes the bottom of the electrolytic cell.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
