Description

Anode pre-culture electrolytic tank cover plate Technical Field The utility model relates to the technical field of anode pre-culture, in particular to a cell cover plate of an anode pre-culture electrolytic cell. Background When the anode pre-culture electrolytic tank is used, a tank cover plate is required to be additionally arranged on the anode pre-culture electrolytic tank, so that the electrolytic tank is provided with a closed space, the effective collection of flue gas is ensured, the heat preservation effect is improved, the energy is saved, the consumption is reduced, and the pollution to the environment is reduced. Disclosure of utility model The utility model aims to provide a cell cover plate of an anode preculture electrolytic cell, which is used for solving the problems that a cell cover plate in the background art is inconvenient to detach and can not be opened. The technical scheme is that the anode pre-culture electrolytic tank cover plate comprises a frame body and tank cover plates, wherein the frame body is detachably arranged at the upper end part of an electrolytic tank, the tank cover plates are arranged on the frame body, each tank cover plate comprises baffle plates which are arranged on two sides of the frame body in a sliding mode, cover plates which are arranged on the two baffle plates in a sliding mode, each cover plate comprises a support frame which is in sliding fit with each baffle plate, and a plurality of baffle strips which are arranged at equal intervals along the length direction of the support frame, the support frame is divided into a plurality of observation cavities by the baffle strips, and the cover plates are arranged in the observation cavities in a sliding mode. Further, the cover plate consists of a first cover plate and a second cover plate which is in sliding fit with the first cover plate, and the first cover plate is in sliding connection with the side wall of the observation cavity. Further, an anode guide rod groove and a burner hole are formed in the frame body. Furthermore, the upper end of the first cover plate and the bottom end of the second cover plate are respectively provided with a bolt hole, limiting holes matched with the bolt holes are formed in the upper end and the lower end of the supporting frame, and bolt rods are arranged in the bolt holes. Compared with the prior art, the utility model has the following beneficial effects: 1. Compared with the traditional welded fixed structure, the whole trough cover plate can be disassembled in a segmented way, and damaged parts only need to be partially disassembled during maintenance, so that the working efficiency is improved, and the labor cost is reduced. 2. The cover plate is divided into equidistant observation cavities through the grid system of the support frame and the barrier strips, and the cover plate is matched with the sliding cover plate (the second cover plate slides in the second cover plate), so that the local opening and closing are realized, a specific cavity can be opened in a targeted manner during fault investigation, the defect that the whole cover plate must be disassembled in the traditional scheme is avoided, and the overhaul time is shortened. 3.
