Description

Technical Field

[0001] This utility model belongs to the field of electrolytic cell technology, specifically relating to an automatic cell gate for electrolytic cells. Background Technology

[0002] The original electrolytic cell doors at the caolu aluminum electrolytic plant were double-leaf doors that were manually opened from the left and right. After testing, it was found that when the electrolytic cell was in operation, the electrolytic worker had to run to the electrolytic cell to open the door and extinguish the aluminum outlet. The entire process took 12 seconds. The whole process posed a safety risk of tripping while running and the extinguishing efficiency was low. Utility Model Content

[0003] The present invention aims to at least partially solve the aforementioned technical problems. Therefore, the objective of this invention is to provide an automatic tank door for an electrolytic cell.

[0004] The technical solution adopted in this utility model is as follows:

[0005] An automatic electrolytic cell door includes a door frame, with slide rails installed on the left and right sides of the door frame, and a lifting door installed between the two slide rails. The lifting door includes a rectangular frame and a door panel disposed on the rectangular frame. Rollers are provided on both the left and right sides of the rectangular frame, and the rollers are installed in the slide rails. A guard plate is provided at the lower end of the rectangular frame, and an insulating layer is provided on the side of the guard plate facing the door frame. An electric lifter is installed on the door frame, and a fixed pulley is provided on the rectangular frame. The electric lifter is connected to the fixed pulley through a lifting rope. A limit switch and a proximity switch are provided on the door frame, and both the limit switch and the proximity switch are electrically connected to the electric lifter.

[0006] Preferably, at least one slide rail on the door frame is detachable. One side of the door panel is provided with crisscrossing reinforcing ribs.

[0007] Preferably, the rectangular frame, door panel, and reinforcing ribs are all made of stainless steel. The rollers and fixed pulleys are all made of plastic.

[0008] The beneficial effects of this utility model are as follows:

[0009] The automatic electrolytic cell door provided by this utility model has an electric lifter controlled by the cell pressure. After the electric lifter is activated, it automatically pulls the lifting door up and opens. During this process, the travel limit switch and the proximity switch have double upper limit switches to protect the door frame and the lifting door from damage. Attached Figure Description

[0014] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. The components of the embodiments of the present invention described and shown in the accompanying drawings herein can generally be arranged and designed in various different configurations.

[0015] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, the automatic electrolytic cell door of this embodiment includes a door frame (not shown in the figure), slide rails 1 are installed on the left and right sides of the door frame, and a lifting door is installed between the two slide rails 1. The lifting door includes a rectangular frame 2 and a door panel 3 on the rectangular frame 2. One side of the door panel 3 is provided with crisscrossing reinforcing ribs 7. The rectangular frame 2, the door panel 3 and the reinforcing ribs 7 are all made of stainless steel.

[0018] Two rollers 4 are provided on both the left and right sides of the rectangular frame 2. The rollers 4 are slidably installed in the slide rail 1. The rollers 4 and the slide rail 1 work together to ensure that the lifting door will not shake when it is raised or lowered. One of the slide rails 1 on the door frame is detachable for easy replacement of the lifting door in the future.

[0019] An electric lift is installed on the door frame. A fixed pulley 6 is located on the rectangular frame 2. The electric lift is connected to the fixed pulley 6 via a lifting rope. Limit switches and proximity switches are installed on the door frame, both electrically connected to the electric lift. The electric lift is controlled by a pressure gauge and includes a motor with a lifting speed of 10 meters per minute. Both the limit switches and proximity switches have dual upper limit settings for protection, preventing damage to the door frame and the lift door.

[0020] Both roller 4 and fixed pulley 6 are made of plastic. The lower end of the rectangular frame 2 is provided with a guard plate 5, and the side of the guard plate 5 facing the door frame is provided with an insulating layer; thus, the entire lifting door is insulated from the door frame.

[0021] This embodiment replaces the electrolytic cell door with an automatic cell door controlled by cell pressure, based on the site conditions. This reduces the need for electrolyzer operators to open the cell door during electrolytic cell operation; operators only need to insert the effect rods. It also improves the efficiency of the quenching process, saving 6 seconds for each cell quenching and reducing the power consumption per cell operation by 20 degrees Celsius. Furthermore, it avoids accidents such as falls and injuries from running during operation, and electrolyte splashing and burns from opening the cell door. It also reduces damage caused by human operation, improves the sealing and insulation of the electrolytic cell door, and extends the replacement and maintenance cycle of the cell door from once a month to once every six months, thus reducing economic costs.

[0022] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
