Description

Unmanned drum-type magnetic separator for coal dressing Technical Field The utility model relates to the field of drum-type magnetic separators, in particular to an unattended drum-type magnetic separator for coal dressing. Background The magnetic separator is used as common mechanical equipment in coal preparation plants, is mainly used for recovering heavy media in a heavy medium coal preparation process, and aims to recover a large amount of magnetic iron powder contained in suspension produced by coal washing and realize recycling. In coal washing production, the running condition of the magnetic separator is important, and particularly whether the liquid level of the magnetic separator is stable or not directly influences the recovery efficiency, so that the production cost of a coal preparation plant is influenced. The Chinese patent discloses a drum-type magnetic separator for coal (grant bulletin No. CN 209753111U), which can solve the problems that the magnetic separator of a plurality of domestic coal preparation plants always has unstable liquid level and suddenly rises and falls in production, influences the recovery efficiency of magnetic substances, causes the increase of system medium consumption, increases the production cost of coal washing and the like. In this patent, when the scraper blade collects the magnetic substance, the colliery falls on the scraper blade easily to lead to the separation effect poor, need the manual work to select it and handle to the magnetic substance is attached to the scraper blade easily and is difficult to slide down the processing, need the problem of manual push processing. Disclosure of utility model In order to solve the technical problems, the utility model provides an unmanned roller type magnetic separator for coal dressing, which comprises a box body and a roller, wherein the roller is rotatably arranged on the right side end surface in the box body through a bearing, a first motor is arranged on the left side end surface of the roller, a through hole is formed in the bottom of the box body, a discharge hole is arranged at the bottom of the through hole, an electromagnetic valve is arranged on the outer side wall of the discharge hole, an inclined hole is arranged on the front side end surface of the box body, a scraping plate is arranged in the inclined hole, an inclined table is arranged on the front side end surface of the box body, an electric sliding block is arranged on the upper end surface of the inclined table, a connecting plate is arranged on the upper end surface of the connecting plate, and a collecting box is arranged obliquely below the scraping plate. Preferably, triangular tables are symmetrically arranged on the front and back of the inner bottom of the box body, a second screw is rotatably arranged on the right side end surface of the box body through a bearing, a push plate is symmetrically and spirally connected on the left side wall of the second screw, a second motor is arranged on the left side end surface of the second screw, and fixing rods are symmetrically arranged on the left side wall and the right side wall of the box body, penetrate through the push plate and are connected with the push plate in a sliding fit mode.
