Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic aluminum production, in particular to a two-level measuring device. Background Art

[0002] In the aluminum smelting industry, the aluminum electrolysis process is a process in which the aluminum oxide dissolved in the electrolyte undergoes an electrochemical reaction at the cathode and anode of the electrolytic cell at a temperature between 940 and 960°C, with molten cryolite as the solvent, aluminum oxide as the solute, carbon as the anode, and aluminum liquid as the cathode, to electrolyze metallic aluminum at the cathode and CO and CO2 gases at the anode. Liquid aluminum and liquid electrolyte coexist in the electrolytic cell. Due to the different densities of the two substances, two layers are formed, with the aluminum liquid in the lower layer and the electrolyte liquid in the upper layer. The important technical indicator for determining whether the aluminum electrolytic cell is operating well is the height of the electrolyte liquid and the aluminum liquid, referred to as the two levels. The process of measuring the electrolyte liquid level and the aluminum liquid level is called two-level measurement.

[0003] At present, general measurement usually adopts manual measurement method, that is, use an L-shaped measuring rod, insert one end of the measuring rod into the liquid of the aluminum electrolysis cell, and leave it for a period of time. The electrolyte liquid and aluminum liquid will adhere to the rod, and there is a clear dividing line between the two solutions. One person holds the measuring rod, and the other person measures. The height of the two solutions can be measured after two measurements. However, this measurement method is inefficient on the one hand, and there are safety hazards on the other hand, because the high-temperature rod (generally about 800℃) is not easy to operate under the influence of the strong magnetic field of the aluminum electrolysis workshop, and it is easy to burn the hands. After the measurement, the rod needs to be slapped on the ground to slap off the electrolyte skin stuck on the rod to facilitate the next measurement. Finally, manual cleaning is required, which is time-consuming and labor-intensive, inefficient, and economical.

[0004] Therefore, in view of the above problems, a two-level measurement device is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figure 1-6 As shown, the utility model provides a technical solution:

[0033] A two-level measuring device is used in conjunction with a measuring brazing rod 1. The measuring brazing rod 1 is arranged in an L shape, one end of the L shape is an insertion end contacting an electrolyte liquid, and the other end is a control end where a control handle is arranged, and a stopper is arranged below the control handle of the control end. Preferably, the length direction of the stopper and the insertion end are parallel to each other. The two-level measuring device comprises: a collecting box 2, the interior of which is arranged as a cavity and the upper end is open, and is used to collect the electrolyte skin that falls off the measuring brazing rod 1; a positioning component 3, which is arranged on the collecting box 2 and is used to place and limit the measuring brazing rod 1; a measuring component 4, which is movably arranged on one side of the collecting box 2 and comprises a measuring ruler 41, and is used to measure the insertion end of the measuring brazing rod 1; and a skin scraping component 5, which is arranged on the upper side of the opening of the collecting box 2 and is used to scrape off the electrolyte skin attached to the measuring brazing rod 1.

[0034] In this embodiment, the cavity inside the collecting box 2 is configured to be a funnel shape that is wide at the top and narrow at the bottom, and the bottom of the funnel is open and provided with a hinge plate 21 that can be opened and closed. When the electrolyte skin is fully collected in the collecting box 2 or when the electrolyte skin needs to be processed, the hinge plate 21 is opened to allow the electrolyte skin to be discharged in a centralized manner without the need for manual cleaning and processing, thereby reducing labor intensity and improving efficiency.

[0035] In another embodiment, a plug plate is provided at the bottom of the collecting box 2, and a slot is provided at the side of the opening of the funnel-shaped bottom. The plug plate is inserted into the slot to achieve a blocking effect. When the electrolyte skin needs to be unloaded, the plug plate is pulled out, and the electrolyte skin flows out of the collecting box 2 under the action of gravity, thereby improving economy.

[0036] In this embodiment, the positioning assembly 3 includes a support column 31 and a stop column 32, and the support column 31 and the stop column 32 are respectively horizontally arranged on both sides of the collection box 2, and the distance between the support column 31 and the stop column 32 is the same as or slightly larger than the distance between the stop block and the insertion end of the measuring drill 1, so that the insertion end of the measuring drill 1 is located on the side of the support column 31 away from the stop column 32, and the stop block of the measuring drill 1 is located on the side of the stop column 32 away from the support column 31, and the support column 31 and the stop column 32 can be stuck together between the stop block and the insertion end of the measuring drill 1, and the height of the support column 31 and the stop column 32 are set to the same height, so as to facilitate the placement of the measuring drill 1 and make the insertion end placed vertically, which is convenient for measurement and improves the accuracy of measurement.

[0037] In this embodiment, the measuring assembly also includes a guide rod 42, the axis of which is vertically arranged on a side of the collecting box 2 close to the support column 31, a sleeve 43 is slidably arranged on the guide rod 42, and a measuring ruler 41 is arranged on the side of the sleeve 43 close to the support column 31. The length direction of the measuring ruler 41 is parallel to the axis direction of the guide rod 42, and the sleeve 43 is used to drive the measuring ruler 41 to move up and down along the guide rod 42 to adapt to the boundary line between aluminum liquid and electrolyte on the measuring solder 1 at different heights, which facilitates measurement and improves the practicability of the device.

[0038] In this embodiment, a locking assembly 6 is provided on the sliding sleeve 43, and the locking assembly 6 includes a holding clamp 61 and a spring 62. The holding clamp 61 is rotatably provided on the sliding sleeve 43 in an X shape. One end of the holding clamp 61 can contact with the guide rod 42 and is used to clamp the guide rod 42 to prevent the measuring ruler 41 from falling during measurement, thereby improving stability. A spring 62 is provided at the other end of the holding clamp 61 to provide a clamping force for the holding clamp 61. Specifically, when in use, the hand holds the end of the holding clamp 61 with the spring to compress the spring. Since the holding clamp 61 is in an X shape, the end of the holding clamp 61 that contacts the guide rod 42 opens, which can drive the sliding sleeve 43 and the measuring ruler 41 to slide along the guide rod 42. After the measuring ruler 41 reaches the position, the hand is released, and the holding clamp 61 clamps the guide rod 42 again under the action of the spring, thereby temporarily fixing the position of the measuring ruler 41, making it convenient for the measurement personnel to concentrate on observing the measurement values, thereby improving the practicality and safety of the device.

[0039] In another embodiment, one end of the holding clamp 61 that is clamped with the guide rod 42 is configured to fit the shape of the guide rod 42 to increase the contact area with the guide rod 42 and further improve stability.

[0040] In this embodiment, the measuring ruler 41 is marked with scale along its length direction, and the zero point line of the scale is located in the middle of the measuring ruler 41, and the scale value increases toward the two ends of the measuring ruler 41. When in use, the zero point line of the scale and the boundary line between the aluminum liquid and the electrolyte at the insertion end are located at the same height position, that is, the specific values ​​on both sides can be measured and read at one time, without the need for two movements and readings, thereby improving the measurement efficiency.

[0041] In this embodiment, the scraping assembly 5 includes a scraping frame 51 and a sleeve 52. The scraping frame 51 is arranged on the collecting box 2. The sleeve 52 is arranged on the scraping frame 51, and the sleeve 52 is located above the opening of the collecting box 2. The diameter of the sleeve 52 is consistent with or slightly larger than the diameter of the insertion end of the measuring pick 1 before insertion. The inner surface of the sleeve 52 is covered with tooth-shaped protrusions, which are used to scrape off the electrolyte skin on the surface of the measuring pick 1 after insertion and measurement, so as to avoid the phenomenon that the measuring pick 1 hits the ground and causes the electrolyte skin to fly, thereby reducing labor intensity and improving economy.

[0042] In another embodiment, multiple sleeves 52 can be provided and arranged to be replaceable to avoid repeated use of a sleeve causing wear of the tooth-shaped protrusions, thereby reducing the scraping effect on the measuring brazing rod 1, adversely affecting the measurement, and improving the practicality of the device.

[0043] In this embodiment, a handle 7 is provided on one side of the collection box 2, and moving wheels 8 are provided at the bottom of the collection box, so as to facilitate the movement of the device, avoid scalding of the staff, and improve the practicality and safety of the device.

[0044] Working principle: First, the operator holds the control end of the measuring pick 1, inserts the insertion end of the measuring pick 1 into the liquid of the aluminum electrolytic cell for a period of time, and then takes it out. The measuring pick 1 is placed on the support column 31 and the stop column 32, and the measuring pick 1 can be rotated so that the support column 31 and the stop column 32 are located between the insertion end of the measuring pick 1 and the stop block and are stuck. At this time, the operator can let go and the measuring pick 1 is supported by the support column 31; then the operator holds the holding clamp 61, drives the sliding sleeve 43 and the measuring ruler 41 to move, and makes the zero scale line on the measuring ruler 41 and the boundary line between aluminum liquid and electrolyte displayed on the insertion end at the same height position, and releases the holding clamp 61. The clamp 61 positions the measuring ruler 41, and then the height values ​​of the electrolyte liquid and the aluminum liquid can be read and recorded through the scale; after the measurement is completed, the operator picks up the measuring pick 1 again, and inserts the insertion end of the measuring pick 1 into the sleeve 52, and the toothed protrusions on the inner surface of the sleeve 52 scrape the electrolyte skin on the surface of the measuring pick 1, and the scraped electrolyte skin falls into the collection box 2 due to gravity. The measuring pick 1 can be repeatedly pulled in and out to remove the electrolyte skin more completely, which is convenient for the next measurement; after the electrolyte skin in the collection box 2 is full, the device is moved to the processing position, and then the hinge plate 21 is opened, so that the electrolyte skin is unloaded from the collection box 2 for centralized processing.
