Description

Technical Field

[0001] This utility model relates to the field of self-baking electrode auxiliary equipment, specifically to an industrial self-baking electrode paste surface height measuring device. Background Technology

[0002] Self-baking electrodes are widely used in the metallurgical industry due to their low cost, serving as key equipment in smelting furnaces such as submerged arc furnaces and settling furnaces. The height of the electrode paste surface has a significant impact on electrode performance. If the paste surface is too low, the electrode length cannot be replenished in time after a hard breakage. If the paste surface is too high, it can exceed the load of the electrode lifting cylinder, affecting normal electrode operation. Therefore, timely measurement of the electrode paste surface height is crucial. Traditional electrode paste surface height measurement involves manual calculation using a plumb bob, which is inefficient and poses safety risks such as electric shock and falls to the measurement personnel. This new measuring device does not interfere with electrode paste application and shell connection operations, offering significant advantages and practical value. Utility Model Content

[0003] The purpose of this invention is to provide an industrial self-baking electrode paste device.

[0004] An industrial self-baking electrode paste-making device includes a microwave radar ranging mechanism and a laser ranging mechanism. The microwave radar ranging mechanism includes a bracket set on the electrode paste-making plane. The bracket is connected to a microwave radar ranging sensor via a rotating arm. The rotating arm is connected to a threaded vertical shaft via a bearing. The vertical shaft is screwed into an internal threaded hole at the top of the bracket, realizing the rotational movement, position fixation, and height adjustment of the rotating arm. The microwave radar ranging sensor can be moved to directly above the electrode shell or to avoid the paste-making / shell-joining operation position under the drive of the rotating arm.

[0005] The laser ranging mechanism consists of a laser ranging sensor fixed to an electrode lifting platform. The electrode lifting platform is located on both sides of the electrode housing. One end of the platform is connected to a lifting cylinder mounted on a lifting cylinder platform, and the other end is fixed to the electrode casing and electrode brake ring. The electrode brake ring is connected to the electrode housing via a brake shoe. Conductive copper tiles and a conductive copper tile holder are suspended from the bottom of the electrode casing. The microwave radar ranging sensor and the laser ranging sensor are connected to a PLC controller. The laser ranging sensor is fixed to the electrode lifting platform by a fixed bracket, which has threaded through holes for adjusting the sensor's installation position.

[0006] The beneficial effects of this utility model are as follows: This utility model measures the distance from the electrode paste inside the electrode shell to the center of the upper part of the electrode shell using a microwave radar ranging mechanism, and measures the height of the electrode movement in real time by installing a laser ranging mechanism on the electrode lifting cylinder platform. The measured distance is transmitted to the mathematical model set in the PLC, thus realizing the dynamic real-time measurement of the height of the self-baking electrode paste surface. This utility model can realize the real-time measurement of the electrode, provide a data basis for the early warning of hard or soft electrode breakage, facilitate the control of the furnace condition, avoid the risk of electric shock to personnel using traditional measurement methods, and at the same time, significantly improve the measurement efficiency and reduce the workload of personnel adding electrode paste.

Detailed Implementation

[0013] The present invention will now be described in detail with reference to the accompanying drawings.

[0014] like Figure 1-5 As shown, an industrial self-baking electrode paste-making device includes a microwave radar ranging mechanism and a laser ranging mechanism. The microwave radar ranging mechanism includes a support 1 mounted on an electrode paste-making platform 16. The support 1 is connected to a microwave radar ranging sensor 3 via a rotating arm 2. The rotating arm 2 is connected to a threaded vertical shaft 201 via a bearing. The vertical shaft 201 is screwed into an internal threaded hole at the top of the support 1, thereby realizing the rotational movement and position fixation of the rotating arm 2, and allowing for appropriate adjustment of the height of the microwave radar ranging sensor 3.

[0015] The microwave radar ranging sensor 3, driven by the rotating arm 2, can be moved to directly above the electrode shell 4 or to avoid the paste / shell-joining operation position. When the electrode needs paste addition and shell joining, simply rotate the rotating arm to the other side. After the operation is completed, the microwave radar ranging sensor 3 can be rotated to directly above the center of the electrode shell 4. At this time, the microwave radar ranging sensor 3 can measure the distance h from the electrode paste surface 11. Simultaneously, based on the height of the support 1, the thickness of the rotating arm 2, and the installation position of the microwave radar ranging sensor 3, the distance H from the microwave radar ranging sensor 3 to the furnace top platform 14 can be obtained. The microwave radar ranging mechanism is relatively lightweight and can be moved to the surrounding electrodes to participate in the electrode surface height measurement.

[0016] The laser ranging mechanism consists of a laser ranging sensor 12 fixed on an electrode lifting platform 6. The electrode lifting platform 6 is located on both sides of the electrode shell 4. One end of the electrode lifting platform 6 is connected to a lifting cylinder 7 mounted on a lifting cylinder platform 15, and the other end is fixed to the electrode casing 8 and the electrode brake ring 5, respectively. The electrode brake ring 5 is connected to the electrode shell via a brake shoe 13. A conductive copper tile 9 and a conductive copper tile holder 10 are suspended from the bottom of the electrode casing 8. The copper tile holder 10 uses springs to hold the conductive copper tile 9 against the surface of the electrode shell 4. The conductive copper tile holder 10 is fixedly connected to the electrode casing 8 via a hanging component 1001, where 1002 is an insulating layer. The upper and lower flanges are bolted together and equipped with insulating gaskets. The lifting cylinder 7 drives the electrode lifting platform 6 to move, which in turn moves the electrode casing 8 and the electrode brake ring 5, thereby moving the electrode shell 4. The laser ranging mechanism is used to measure the height of the electrode movement in real time (i.e., the distance t from the electrode lifting platform to the lifting cylinder platform 15).

[0017] The laser rangefinder 12 is fixed on the electrode lifting platform 6. A mounting bracket 1201 for the laser rangefinder 12 is welded onto the electrode lifting platform 6. The mounting bracket 1201 has threaded through holes to adjust the sensor's installation position. As the electrode moves, the laser rangefinder 12 can measure the distance t between the lifting rod platform and the lifting cylinder platform 15 in real time.

[0018] The furnace top platform 14 and the lifting cylinder floor 15 are in fixed positions with a fixed spacing of c. The electrode lifting platform 6, electrode sleeve 8, conductive copper tile 9, and conductive copper tile holder 10 are all fixedly connected, and their relative positions are fixed. The distance from the upper edge of the conductive copper tile 9 to the laser rangefinder 12 is a fixed value c1. The electrode paste surface height is the distance from the upper edge of the conductive copper tile 9 to the electrode paste surface.

[0019] The signals from microwave radar ranging sensor 3 and laser ranging sensor 12 are transmitted to the PLC controller via a signal transmission line. The calculation model is embedded in the controller program through an algorithm. The PLC controller receives the signals from the microwave radar and laser ranging sensors and calculates the electrode paste height (d) through a mathematical model. The calculation formula is: d=Hh-(c+t-c1), realizing real-time measurement of the electrode paste height.
