[0002] The solid-liquid separation of high-solid content medium-temperature coal tar slag has always been a pain point in the industry. The definition of high solid content is that the solid content of medium-temperature coal tar slag exceeds 50%. Many horizontal centrifuges at home and abroad have difficulty in making breakthroughs in this regard. The industry's treatment methods for high-solid content medium-temperature coal tar slag are: one is to burn it directly, which wastes resources; the other is to use pyrolysis technology, but it consumes a lot of energy.

[0003] To this end, the patent specification with publication number CN206519256U discloses a variable pitch horizontal centrifuge, which belongs to the field of horizontal centrifuges and aims to provide a variable pitch horizontal centrifuge that can reduce the water content of extruded materials. The key points of its technical solution are: a variable pitch horizontal centrifuge, including a concentric drum and a drum, a feed pipe is arranged in the drum, a feed port is arranged on the drum, one end of the drum is arranged as a cone end, a spiral sheet is arranged on the circumference of the drum, a slag outlet is arranged on the side wall of the drum cone end, and a liquid outlet is arranged at the other end, and the pitch of the spiral sheet at the drum cone end gradually decreases from the liquid outlet to the slag outlet.

[0030] The fixed shaft 602 is installed on the top of the mounting seat 601 , and the fixed shaft 602 is symmetrically distributed about the central axis of the mounting seat 601 .

[0031] By installing a mounting base 601 at the bottom end of the main motor 603, the main motor 603 is divided into four groups of fixed shafts 602, which are divided into two groups and fixed to the top of the mounting base 601 through a fixing plate.

[0037] The high-solid-content medium-temperature coal tar slag is pre-heated and tempered in the tempering box for pretreatment. To ensure that the temperature and uniformity of the raw materials meet the requirements of industry and mining before entering the horizontal centrifuge, adjust the height of the weir plate according to the solid content of the material to control the dryness and wetness of the discharge port. It should not be too dry, which will easily block the machine, nor too low, which will affect production efficiency. Observe the current changes of the main and auxiliary motors at any time to judge the flow of materials in the cavity. If the current of the auxiliary motor exceeds the set limit, it may be that there is too much material accumulation, the spiral pushes the material in time, and the dry matter is easy to reversely accumulate in the drum cavity, which means that the centrifuge loses its separation function. Stop feeding immediately and reduce the speed of the main engine. Wait until the auxiliary current drops below the set safety value before continuing feeding and separation.
