Description

Detection device for loosening bearing steel rope of yellow phosphorus furnace

Technical Field

The invention relates to the field of detection devices for loosening of bearing steel ropes, in particular to a detection device for loosening of a bearing steel rope of a yellow phosphorus furnace.

Background

In the normal smelting process of the yellow phosphorus furnace, the situation that the electrode is cushioned by raw materials often occurs, when the situation occurs, if the electrode is not found in time and is continuously discharged, the electrode bearing steel rope is loosened due to the fact that the electrode is not tensioned, when the bearing steel rope is loosened to a certain extent, the electrode is possibly touched, because the electrode is provided with the AC voltage of about 200V, the bearing steel rope is grounded, once the steel rope touches the electrode, a short circuit accident occurs, the steel rope is likely to be fused due to high temperature caused by the short circuit, the electrode is caused to lose bearing support, more serious accidents such as electrode deflection and even breakage are further caused, and serious potential safety hazards are caused for personnel working around the electrode of the yellow phosphorus furnace. There are also automatic systems for controlling electrode deflection by recognizing the electrode deflection of yellow phosphorus furnaces, and a detecting device for detecting the loosening of a bearing steel rope of a yellow phosphorus furnace is provided visually and simply.

Disclosure of Invention

In order to achieve the aim of the invention, the invention adopts the following technical scheme: the device comprises a bearing steel cable, wherein one end of the bearing steel cable bypasses a guide part and is connected with an electrode, and the other end of the bearing steel cable is connected with a traction mechanism through a balance triangle; the bottom of the balance set square is fixed with a steel rope support, and an ultrasonic ranging unit for detecting the distance between the balance set square and the ground is placed on the steel rope support.

Preferably, the ultrasonic ranging unit comprises an ABS waterproof box, an ultrasonic module arranged in the ABS waterproof box, a WIFI module and a power module, wherein an ultrasonic probe is arranged on the ultrasonic module, the ultrasonic module is connected with the WIFI module through a TTL serial port, and a plurality of WIFI modules are connected with the wireless router.

Preferably, the power module is connected with the WIFI module, and DC3.3V direct current voltage is supplied to the WIFI module through the LM1117T-3.3V three-terminal voltage stabilizing chip; the power supply module and the ultrasonic module are directly supplied with DC5V direct current voltage and current smaller than 100mA by an external power supply.

Preferably, the number of the bearing steel cables is three.

Preferably, the guiding component is a guiding wheel or a guiding ring.

The invention has the beneficial effects of detecting the looseness of the bearing steel cable in real time and avoiding causing greater potential safety hazard to operators. Specifically, the invention detects the tension value of the bearing steel cable through the ultrasonic ranging unit, the standard distance L between the ultrasonic ranging unit and the ground, the current distance M between the ultrasonic ranging unit and the ground, the tension value K=L-M of the bearing steel cable, when K is larger than the set allowable value, the bearing steel cable is regarded as an electrode pad to be dead, and workers can process raw materials in the furnace in time; correspondingly, when the electrode is in pad dead, the electrode weight at the tail end of the bearing steel cable is born by the bottom pad, and the balance set square can fall down to the ground due to insufficient tension of the bearing steel cable, so that the situation that the bearing steel cable is loose is more intuitively reflected.
