Description

Technical Field

[0001] The utility model relates to the technical field of a conductive measuring device for an anode guide rod of an aluminum electrolytic cell, in particular to a real-time conductive measuring device for an anode guide rod of an aluminum electrolytic cell. Background Art

[0002] In the production process of electrolytic cells in the aluminum electrolysis industry, the anode current distribution needs to be measured every day. The traditional measurement method is manual measurement through a handheld electric meter. However, manual measurement can only measure one anode at a time. Not only is the measurement procedure complicated and labor-intensive, but it is also time-consuming and inefficient. At the same time, the measurement results cannot be sent to the computer control system in real time. Instead, the measurement results need to be submitted to relevant personnel first, and then input into the control system by relevant personnel according to the regulations. There is a time difference in the measurement results. Therefore, the existing measurement method cannot truly reflect the distribution of the anode current of the electrolytic cell.

[0003] In order to solve the above problems, patent publication number: CN106283120B provides an aluminum electrolytic cell busbar current measurement device and an anode current measurement system and method. The principle is that a card rack is provided on the busbars on both sides of the anode guide rod of the electrolytic cell, and the card rack is equidistantly installed on the busbar. The card rack is equipped with a busbar voltage and temperature collector. The voltage signal measured by the busbar voltage and temperature collector is transmitted to the busbar current collector through a wire. The device requires the busbar current collector to determine the busbar resistance according to the busbar temperature fed back by the electronic temperature sensing device in the busbar voltage and temperature collector, and according to the busbar resistance and the busbar equidistant voltage fed back by the busbar voltage and temperature collector, the busbar current on one side of the anode guide rod is obtained according to the voltage and resistance.

[0004] The above-mentioned aluminum electrolytic cell busbar current measurement device and anode current measurement system and method have a complex overall structure and are installed above the busbar. When measuring the real-time current, it is necessary to obtain the busbar current distribution based on the busbar resistance and the busbar voltage and the busbar equidistant voltage fed back by the temperature collector. The current on the anode guide rod cannot be measured directly, resulting in an inability to accurately judge the operating status of the electrolytic cell. Utility Model Content

[0005] The utility model aims to provide a real-time measurement device for the conductivity of an anode rod of an aluminum electrolysis cell, so as to solve the problem that an existing aluminum electrolysis cell busbar current measurement device and an anode current measurement system and method cannot directly measure the anode rod current.

[0006] In order to achieve the above-mentioned purpose, the basic solution provided by the utility model is: a real-time measurement device for the conductivity of the anode guide rod of an aluminum electrolytic cell, comprising a fixed bracket, a side flap is hinged on the fixed bracket, a current collection unit for measuring the current of the anode guide rod is provided on the side flap, and a limit assembly for limiting the rotation of the side flap is provided on the fixed bracket.

[0007] The principle and beneficial effect of the utility model are as follows: the fixed bracket is fixedly connected under the busbar close to the guide rod, and the current collection device on the side flap is in contact with the anode guide rod, so that the real-time current of the anode guide rod can be directly collected, so as to judge the operating status of the electrolytic cell. When the guide rod needs to be replaced, the side flap can be prevented from rotating by the limit assembly. The device has a simple structure and is easy to operate.

[0008] Option 2 is the preferred option of the basic option. The current collection device includes a contact pin, a wire is connected to the contact pin, and the wire is connected to a main control box. The contact pin is in direct contact with the anode guide rod, and the real-time data of the current on the anode guide rod is transmitted to the main control box. Real-time data collection can be achieved, and the monitoring of the current distribution of the anode guide rod can be increased.

[0009] Plan three is the preferred option of the basic plan. The limiting assembly includes a sleeve A and a sleeve B. The sleeve A and the sleeve B are nested and connected. A compression spring is arranged in the sleeve B. A sleeve bracket A is fixedly connected to the fixed bracket. The sleeve bracket A is connected to the sleeve A through a hinge rod 1. A sleeve bracket B is fixedly connected to the side flap. The sleeve bracket B is connected to the sleeve B through a hinge rod 2. When replacing the anode guide rod, the side flap is flipped 90 degrees. At this time, the sleeve B is nested and overlapped in the sleeve A. Due to the outward pressure generated by the compression spring in the sleeve B, the side flap cannot rotate, so it is convenient to replace the guide rod.

[0010] Option 4 is a preferred option of Option 2. The contact pin is provided with a thread, and the contact pin and the side flap are threadedly connected to facilitate adjustment of the contact pin after replacing the anode guide rod.

[0011] Option 5 is a preferred option of Option 2. Two insulating washers are sleeved on the contact pin. The two insulating washers are located on both sides of the side flap to prevent electric shock and increase safety when flipping the side flap. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is further described in detail below through specific implementation methods:

[0017] The reference numerals in the drawings of the specification include: 1. fixed bracket, 3. contact pin, 4. wire, 5. main control box, 6. side flap, 7. bushing A, 8. bushing B, 9. bushing bracket A, 10. bushing bracket B, 11. compression spring, 12. insulating gasket.

[0018] Example

[0019] like Figures 1 to 4 The present invention shows a real-time measurement device for the conductivity of an anode guide rod of an aluminum electrolytic cell, comprising a fixed bracket 1, a side flap plate 6 is hingedly connected to the fixed bracket 1, a sleeve bracket B10 is fixedly connected to the side flap plate 6, a sleeve bracket B10 is connected to a sleeve B8 via a hinge rod 2, a sleeve bracket A9 is fixedly connected to the fixed bracket 1, a sleeve bracket A7 is connected to the sleeve bracket A9 via a hinge rod 1, the sleeve A7 and the sleeve B8 are nested and connected, a compression spring 11 is arranged in the sleeve B8, a contact pin 3 is threadedly connected to the side flap plate 6, an insulating washer 12 located on both sides of the side flap plate 6 is sleeved on the contact pin 3, a wire 4 is connected to the contact pin 3, and a main control box 5 is connected to the wire 4.

[0020] The implementation method of this embodiment is:

[0021] 1. Before use, first fix the real-time conductivity measuring device of the anode guide rod of the aluminum electrolytic cell to the lower end of the busbar close to the anode guide rod through the fixed bracket 1. When measuring the current of the anode guide rod, the side flap 6 is in a horizontal state with the fixed bracket 1, and the sleeve A7 and the sleeve B8 are in a nested and staggered state. The pressure generated by the compression spring 11 in the sleeve B8 makes the contact pin 3 close to the side of the anode guide rod. The real-time current measured by the contact pin 3 is directly transmitted to the main control box 5 through the wire 4.

[0022] 2. When lifting the busbar, replacing the anode guide rod, or when there is no need to measure the real-time current, there is no need to remove the real-time measuring device for the conductivity of the anode guide rod of the aluminum electrolytic cell. The side flap 6 is flipped 90 degrees, and the side flap 6 drives the contact pin 3 away from the anode guide rod. At this time, the sleeve B8 is nested and overlapped into the sleeve A7. Due to the outward pressure generated by the compression spring 11 in the sleeve B8, the side flap 6 cannot rotate. Then the operations of lifting the busbar and replacing the anode guide rod can be carried out.

[0023] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
