[0002] The electrolytic cell is a key device for realizing the electrolysis process. It converts electrical energy into chemical energy by applying an external DC power supply to the electrolyte solution or molten electrolyte to cause an electrochemical reaction. In the process of electrolytic aluminum, the electrolytic cell is an indispensable device. The electrolytic cell provides a closed high-temperature container for the reaction and separates the anode and cathode products, thereby preventing the aluminum liquid from recombining with oxygen.

[0003] Some small electrolytic cells usually have a cover plate installed on the side for sliding. The electrolytic cell is opened by sliding the cover plate and the material is placed in. When opening the cover plate, the staff manually slides the cover plate to achieve opening and closing. However, manually sliding the cover plate is not only laborious, but also the cover plate on the side of the electrolytic cell will have a certain temperature after the reaction is completed. There is also a risk of burns when touching the cover plate to open it. Utility Model Content

[0004] In response to the deficiencies of the prior art, the present invention provides an automatic opening and closing device for the electrolytic cell cover to solve the problem in the prior art proposed in the background art that workers are required to manually slide the cover when opening the electrolytic cell cover, which is laborious and dangerous.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An automatic opening and closing device for the electrolytic cell cover is installed on the electrolytic cell, and a feed port is provided on the side of the electrolytic cell. The device includes a cover, a lifting assembly, a connecting rod and a rotating opening and closing assembly. The cover is arranged at the feed port of the electrolytic cell, and the lifting assembly is arranged on the side of the electrolytic cell to drive the cover to lift. Two connecting rods are provided, and both connecting rods are arranged on the lifting assembly. The rotating opening and closing assembly is arranged on the connecting rod and the electrolytic cell to drive the cover to open and close.

[0007] Furthermore, the lifting assembly includes a support cover, a reciprocating screw, a motor and a sliding assembly. The support covers are fixedly installed on both sides of the electrolytic cell. The reciprocating screw is rotatably installed in one of the support covers. A matching crescent slider is installed on the reciprocating screw, and one of the connecting rods is fixedly installed on the crescent slider. The motor is installed on the support cover, and the output end of the motor is coaxially connected to the reciprocating screw. The sliding assembly is arranged on the other support cover.

[0008] Furthermore, the sliding assembly includes a sliding rod and a sliding block, the sliding rod is fixedly installed in another supporting cover, the sliding block is slidably installed on the sliding rod, and the other connecting rod is fixedly installed on the side of the sliding block.

[0009] Furthermore, the rotating opening and closing assembly includes a rotating shaft, a rotating gear ring, a rack and a protective assembly. The rotating shaft is rotatably installed between the two connecting rods, and the cover plate is fixedly installed on the rotating shaft. Two rotating gear rings are fixedly installed on the rotating shaft. Two racks are fixedly installed on the side of the electrolytic cell through a support frame. The protective assembly is arranged on the support frame and the connecting rod.

[0010] Furthermore, the protective assembly includes a protective box, a protective cover and a telescopic plate.

DETAILED DESCRIPTION

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 6 The automatic opening and closing device of the electrolytic cell cover is installed on the electrolytic cell 1, and a feed port is opened on the side of the electrolytic cell 1. It includes a cover 2, a lifting assembly, a connecting rod 3 and a rotating opening and closing assembly. The cover 2 is arranged at the feed port of the electrolytic cell 1, and the lifting assembly is arranged on the side of the electrolytic cell 1 to drive the cover 2 to lift. There are two connecting rods 3, and both connecting rods 3 are arranged on the lifting assembly. The rotating opening and closing assembly is arranged on the connecting rod 3 and the electrolytic cell 1 to drive the cover 2 to open and close.

[0025] like Figure 2 and Figure 3As shown, when the cover 2 is opened, the cover 2 is first lifted to a certain height by the lifting assembly. The lifting assembly includes a support cover 4, a reciprocating screw 5, a motor 7 and a sliding assembly. Support covers 4 are fixedly installed on both sides of the electrolytic cell 1. The reciprocating screw 5 is rotatably installed in one of the support covers 4. A matching crescent slider 6 is installed on the reciprocating screw 5, and one of the connecting rods 3 is fixedly installed on the crescent slider 6. The motor 7 is installed on the support cover 4, and the output end of the motor 7 is coaxially connected to the reciprocating screw 5. The sliding assembly is arranged on the other support cover 4. The sliding assembly includes a sliding rod 8 and a sliding block 9. The sliding rod 8 is fixedly installed in the other support cover 4, the sliding block 9 is slidably installed on the sliding rod 8, and the other connecting rod 3 is fixedly installed on the side of the sliding block 9.

[0026] Specifically, start the motor 7, and the output end of the motor 7 drives the reciprocating screw 5 to rotate. It should be added that the shape design of the crescent slider is matched with the spiral groove of the reciprocating screw 5. When the reciprocating screw 5 rotates, the side wall of the spiral groove will generate an axial thrust on the crescent slider 6 embedded therein, thereby causing the crescent slider 6 to move up and down. When the crescent slider 6 reaches the end of the reciprocating screw 5, the crescent slider 6 will smoothly transition to the reverse spiral groove, thereby realizing reciprocating movement. This is a well-known technology and will not be repeated here. The crescent slider 6 drives one of the connecting rods 3 to move up and down, and under the connection of the rotating shaft 10, drives the other connecting rod 3 to move synchronously, so that the sliding block 9 is synchronously lifted and lowered on the sliding rod 8, and then the crescent slider 6 can be limited in rotation, thereby driving the cover plate 2 to rise. It should be added that the output end of the motor 7 has a self-locking function, and a telescopic protective cover is installed on the outside of the reciprocating screw 5 to protect the reciprocating screw 5.

[0027] like Figure 4 、 Figure 5 and Figure 6As shown, after the rise is completed, the cover plate 2 can be driven to rotate by the rotating opening and closing assembly, thereby opening the feed port. The rotating opening and closing assembly includes a rotating shaft 10, a rotating gear ring 11, a rack 12 and a protective assembly. The rotating shaft 10 is rotatably installed between the two connecting rods 3, and the cover plate 2 is fixedly installed on the rotating shaft 10. Two rotating gear rings 11 are fixedly installed on the rotating shaft 10. Two racks 12 are fixedly installed on the side of the electrolytic cell 1 through a support frame 16. The protective assembly is arranged on the support frame 16 and the connecting rod 3, and the limit assembly is arranged on the support frame 16 and the connecting rod 3, the protection assembly includes a protection box 13, a protection cover 14 and a telescopic plate 15. There are two protection boxes 13, the two protection boxes 13 are fixedly mounted on the side of the support frame 16, and the two racks 12 are respectively located in the two protection boxes 13, the sides of the two connecting rods 3 are detachably mounted with two protection covers 14, and the two rotating gear rings 11 are respectively located in the two protection covers 14, one end of the telescopic plate 15 is fixedly mounted on the inner top of the protection box 13, and the other end of the telescopic plate 15 is fixedly mounted on the top of the protection cover 14.

[0028] Specifically, because when the cover plate 2 covers the feed port of the electrolytic cell 1, the rotating gear ring 11 is located below the rack 12, and the rotating gear ring 11 is not engaged with the rack 12, so after the cover plate 2 rises a certain distance, it drives the rotating gear ring 11 to move up to engage with the rack 12, and then continues to drive the cover plate 2 to rise, thereby driving the rotating shaft 10 and the rotating gear ring 11 to move up, so that the cover plate 2 has a certain space when rotating. Under the action of the engagement of the rotating gear ring 11 and the rack 12, the rotating gear ring 11 rotates and then drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the cover plate 2 to rotate and open, so that the cover plate 2 can be opened while rising and rotating.

[0029] When rising, because a telescopic plate 15 is installed between the protective cover 14 and the protective box 13, when the protective cover 14 rises, it can drive the telescopic plate 15 to shorten, and when it moves down, it can synchronously drive the telescopic plate 15 to lengthen. The telescopic plate 15 can protect the meshing between the rack 12 and the rotating gear to prevent dust or impurities from entering, and the protective cover 14 can also protect the rotating gear ring 11. It should be added that a groove is provided at the top of the protective cover 14, and the bottom end of the telescopic plate 15 is connected to the groove. When the rotating gear ring 11 moves up, it can mesh with the rack 12 through the groove, avoiding the long length of the protective cover 14 affecting the meshing between the rotating gear ring 11 and the rack 12, and when it rises to the limit rod inserted into the limit groove of the limit plate, the cover 2 rises and rotates to a horizontal position, reaching an open state, and can limit the rotating shaft 10 to prevent it from rotating.

[0030] After the cam 11 is in the closed position, the gear 12 is rotated and the gear 13 is rotated, so that the gear 12 is rotated and the gear 13 is rotated, thereby the gear 12 is rotated and the gear 13 is rotated.

[0031] When closing, the motor 7 is started again to drive the cover plate 2 to move downward. At this time, the rotating gear ring 11 engages with the rack 12 to drive the cover plate 2 to rotate in the opposite direction and move downward synchronously, and then move to the feed port of the electrolytic cell 1 to seal it.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
