Description
Technical Field
The utility model belongs to the technical field of the mineral processing equipment, specifically speaking relates to a novel automatic moisturizing of laboratory flotation machine device.
Background
In actual mineral flotation of mineral separation, a flotation machine is mechanical equipment for finishing a flotation process. In the flotation machine, the ore pulp treated by adding the medicament is stirred and aerated to ensure that certain ore particles are selectively fixed on the bubbles; floating to the surface of the ore pulp, being scraped to form foam products, and the rest part is remained in the ore pulp so as to achieve the purpose of separating minerals. The ultrasonic liquid level measurement principle is applied to the measurement of the liquid level in the flotation tank, the ultrasonic distance measurement sensor adopts a small-range detection distance smaller than 2m, the working frequency is between 60 and 300kHz, the ultrasonic is suitable for the liquid level in the flotation tank with a small measurement range, and the ultrasonic has the advantages of water resistance and dust resistance.
Because the existing laboratory flotation machine needs to be supplemented with enough water due to the fact that the liquid level of ore pulp is too low in the starting-up operation of ore dressing experiment personnel. In the operation of scraping bubbles in the flotation test, after rough concentration or fine concentration is usually carried out, along with the scraping of a foam layer, the ore pulp liquid level is reduced, so that a flotation machine cannot effectively and timely scrape out a concentrate foam layer, and the experimental index is influenced. The scraper of the flotation machine is shorter than the flotation tank, the foam scraping is divided into three stages, the first stage scraper sinks into the ore pulp, the second stage scraper moves in the ore pulp to scrape out flotation concentrate and carry out a part of ore pulp liquid, and the third stage scraper is lifted out of the ore pulp to complete circular motion. In the process of a flotation experiment, the foam layer and a part of ore liquid are brought out of the flotation tank by the reciprocating circulation of the scraper, so that the liquid level of flotation pulp is continuously reduced, the scraper cannot contact the concentrate foam layer, and finally the concentrate foam layer cannot be scraped. On the other hand, the scraper is made of iron material, and when the scraper touches the edge of the flotation tank and the bottom of the flotation tank, a large impact is caused, and the slurry in the flotation tank can be splashed to the periphery, so that the liquid level of the slurry is lowered. Finally, the level of the flotation liquid level of the laboratory flotation machine directly determines the quality of the flotation experimental indexes, so when the flotation liquid level is too low, an automatic water supplementing device is needed to keep the flotation liquid level in the flotation tank within the scraping and bubble scraping range of the scraper, and good flotation experimental indexes can be ensured.
In view of this, the present invention is provided.
