The object of the invention is achieved in the following way:
a rotary coal-water separator comprises a rotary screen and a water filtering frame, wherein the rotary screen is arranged on rotary wheel sets on two side ends of the water filtering frame, and one rotary wheel set is connected with a power device; a coal outlet and a water inlet are formed in two ends of the drum sieve, and the diameter of the coal outlet is larger than that of the water inlet; a water inlet pipe is arranged on one side of a water inlet of the drum screen, and a water outlet of the water inlet pipe is arranged in the drum screen; a slideway is arranged in the drum screen, one end of the slideway is arranged above the water outlet of the water inlet pipe, and the other end of the slideway is inclined downwards and extends out of the coal outlet of the drum screen;
the inner wall circumference of the drum screen is connected with a plurality of coal scraping screens; the rotary screen and the coal scraping screen are fixedly connected, and the intersection of the rotary screen and the coal scraping screen is a curve; the intersecting curve of the coal scraping screen and the rotary screen is positioned on the space ellipse; taking the working rotation direction as reference, the coal scraping screen is positioned in front of the end close to the coal outlet and close to the water inlet; the coal scraping sieve is upwards inclined at one end close to the coal outlet and fixedly connected with the inner wall of the coal outlet, and the outermost edge of the coal scraping sieve is upwards flanged.
And the coal scraping sieve is provided with sieve pores.
The rotary wheel set is divided into a driving wheel set and a driven wheel set.
Compared with the prior art, the invention has the beneficial effects that: coal water enters the drum screen, the drum screen rotates, the coal screen is scraped to drive coal slime particles to the top, and the coal slime particles are conveyed out of the drum screen due to the fact that the weight of the coal screen falls on the slide way, so that coal water separation integration is achieved, the automation degree of the extraction process is improved, manual operation is not needed in the whole system process, the labor intensity of workers is reduced, the working efficiency is improved, and the labor cost is reduced.
