Description

Technical Field

[0001] This utility model relates to the field of anode pre-baking technology, specifically to a tank cover plate for an anode pre-baking electrolytic cell. Background Technology

[0002] When using an anode pre-baked electrolytic cell, a cell cover plate needs to be installed on it to form a sealed space, ensuring effective collection of flue gas, improving heat preservation, thereby saving energy, reducing consumption, and minimizing environmental pollution. However, existing cell covers are usually fixed to the electrolytic cell, making them inconvenient to disassemble during maintenance and replacement. Moreover, most cell covers are integral structures, which cannot be opened when troubleshooting, requiring the removal of the entire cell cover plate, increasing workload and reducing work efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a cover plate for an anode pre-baking electrolytic cell, which solves the problem mentioned in the background art that the cell cover plate is inconvenient to disassemble and cannot be opened.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cover plate for an anode pre-baking electrolytic cell, comprising a frame detachably mounted on the upper end of the electrolytic cell and a cover plate mounted on the frame. The cover plate includes baffles slidably mounted on both sides of the frame and a cover plate slidably mounted on the two baffles. The cover plate includes a support frame that slidably engages with the baffles and multiple baffles equidistantly arranged along the length of the support frame. The multiple baffles divide the support frame into multiple observation chambers, and a cover plate is slidably mounted in each of the multiple observation chambers.

[0005] Furthermore, the cover plate is composed of a first cover plate and a second cover plate that slides with the first cover plate; the first cover plate is slidably connected to the side wall of the observation cavity.

[0006] Furthermore, the frame is provided with an anode guide rod groove and a burner hole.

[0007] Furthermore, the first cover plate has a pin opening at its upper end and the second cover plate has a bottom end, and the support frame has a limiting hole at its upper and lower ends that matches the pin opening. A pin rod is provided in the pin opening.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. The detachable frame with bolted connection and sliding baffle combination allows the entire trough cover to be disassembled in sections; compared with the traditional welded fixed structure, maintenance only requires partial disassembly of damaged parts, improving work efficiency and reducing labor costs.

[0010] 2. The cover plate is divided into equidistant observation chambers by a grid system of support frame and baffles. With the help of a sliding cover plate (the second cover plate slides inside the second cover plate), partial opening and closing can be achieved. Specific chambers can be opened in a targeted manner during fault diagnosis. This avoids the drawback of having to disassemble the entire cover plate in traditional solutions, thus shortening maintenance time.

[0011] 3. The linkage design between the pin rod and the limiting hole enables the cover plate to form a three-point positioning when closed. Combined with the silicone sealing ring at the anode guide rod groove, it improves the overall airtightness and reduces the escape of flue gas. Attached Figure Description

[0020] Please see Figures 6 to 7 When using electrolytic cell 1 for anode pre-cultivation, a cell cover plate needs to be installed at the upper end of electrolytic cell 1. The cell cover plate of this device consists of a frame 2 that is detachably installed at the upper end of electrolytic cell 1 by bolts and a cell cover plate installed on the frame 2. Multiple anode guide rod slots 9 and burner holes 10 are provided on the frame 2 to install anode guide rods 12 and burners 13. Sealing rings are provided at the installation points to ensure effective collection of flue gas.

[0021] The aforementioned groove cover plate consists of a baffle 3 and a cover plate. The baffle 3 is specifically a right-angled triangle, and the frame 2 is L-shaped. Baffles 3 are provided on both sides of the frame 2. The vertical right-angled side of the baffle 3 slides into the inner vertical side of the frame 2. A retaining plate is provided on the horizontal right-angled side of the baffle 3. A retaining groove adapted to the retaining plate is provided on the inner horizontal side of the frame 2. Threaded holes are provided on both the frame 2 and the baffle 3 to fix the position of the baffle 3 and the frame 2 with bolts. The cover plate specifically consists of a support frame 4, multiple retaining strips 5, and a cover plate. Pressure plates protrude from both the upper and lower sides of the inclined side of plate 3, forming a track between the pressure plates and baffle 3. The support frame 4 slides with the track. After the support frame 4 slides to a suitable position, the position of the support frame 4 and the baffle 3 is fixed by bolts. Multiple baffles 5 are equidistantly arranged along the length of the support frame 4, dividing the support frame 4, which is specifically a rectangular frame, into multiple observation chambers 6. The cover plate, composed of the first cover plate 7 and the second cover plate 8 that slides with the first cover plate 7, is slidably disposed in the observation chamber 6. Specifically, the first cover plate 7 is slidably connected to the side wall of the observation chamber 6.

[0022] In order to fix the position of the first cover plate 7 and the second cover plate 8 when sliding is not required, a pin hole is provided at the upper end of the first cover plate 7 and the bottom end of the second cover plate 8, and a limiting hole adapted to the pin hole is provided at the upper and lower ends of the support frame 4. Finally, a pin rod 11 is provided in the pin hole to fix the position of the first cover plate 7 and the second cover plate 8 on the support frame 4.

[0023] The working principle of this utility model is as follows: During installation, the frame 2 is first installed on the electrolytic cell 1 with bolts, then the baffle 3 is slid into both sides of the frame 2 and the two baffles 3 are fixed to the frame 2 with bolts. Then the support frame 4 containing the cover plate is slid into the inclined side of the two baffles 3 and fixed with bolts.

[0024] If the tank cover plate needs to be replaced or repaired, simply unscrew the bolts and remove the tank cover plate by following the reverse steps of the installation sequence. If it is necessary to observe the working condition of the anode covering material, anode guide rod 12, burner 13, etc. in the electrolytic cell 1, simply remove the pin rod 11 and slide the first cover plate 7 or the second cover plate 8.
