Hot ore vibrating screen for coal mine

Abstract

The invention discloses a hot ore vibrating screen for a coal mine. The hot ore vibrating screen comprises a vibrating screen body, an air draft device and a lifting adjusting device; the vibrating screen body comprises a screen box, four groups of fixed seats, springs, four groups of damping supports and a bottom plate; the damping supports are fixed at the top ends of the fixed seats in an arraymode; the top ends of the damping supports are provided with the springs; the fixed seats are fixed on the front side face and the rear side face of the screen box; the bottom ends of the fixed seatsare connected with the springs; the top end of the screen box is provided with a feed inlet; a vibration exciter is arranged at the position, at the right end of the feed inlet, of the screen box, and two sieve plates are obliquely fixed in the vibration exciter; and the air draft device comprises an exhaust pipe, a multi-pass pipe, an air suction pump and air guide pipes, wherein the air guide pipes are uniformly mounted between the inner walls of the screen box and located between the two sieve plates. The hot ore vibrating screen can perform air suction treatment on the inside of the screen box, so that the temperature inside the screen box is reduced, and the service life of the sieve plates is prolonged advantageously.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a hot ore vibrating screen for coal mines. Background technique [0002] Hot ore vibrating screen is a kind of vibrating screen that adopts dual-axis vibrator, the motor does not participate in the vibration, and the two motors are externally connected to rotate in reverse and synchronously, so that the screen body performs periodic reciprocating motion along the straight line to achieve the purpose of screening. Equipment, when screening hot ore, the temperature inside the screen box is high, resulting in high temperature of the screen box and sieve plate, which is easy to be damaged by thermal expansion. The traditional hot ore vibrating screen cannot cool the inside of the screen box. As a result, the damage to the sieve plate is serious and the service life is low. Contents of the invention [0003] The technical problem to be solved by the present invention i...
