GW-XZ type linear vibrating screen

Abstract

The invention relates to a GW-XZ type linear vibrating screen. The GW-XZ type linear vibrating screen comprises such main parts as a screen box, a large-span vibrating motor based on a steel rope coupling, a gear inclined block type screen plate pressing mechanism, a screen box self-weight screw rod dip angle adjusting mechanism, an electric appliance switch box with a self-control function, a spot melting welding plum-blossom steel foil locking gasket, a parallel combined spring with a hinge support, a screen box support lever with a hinge support and a whole machine base. A large-span vibration exciter based on the steel rope coupling largely improves self stress of a motor, thoroughly breaks through restraint of a G force value suffered by the motor, and greatly optimizes a bearing state of the screen box. The large-span vibrating motor mounted in a socket-plug manner can synchronously adopt a stretching resistant bolt and a shearing resistant bolt to prevent looseness of the bolts. The locking gasket can further prevent looseness of the bolts and screw caps. The electric appliance switch box with the self-control function can electrify and cut off two vibrating motors in turns according to a set time interval to effectively save the electric power, achieves the effects of life prolonging and protection on the motors, and can brake the motors in real time to immediately stop the whole machine.

Description

technical field [0001] The invention relates to a GW-XZ linear vibrating screen, which is suitable for oil and gas drilling engineering, shield engineering, mining engineering and other screening industries that require the use of single-mass inertial vibrating screens for solid-liquid separation or solid particle classification and transportation. department. Background technique [0002] In the existing single-mass, double-motor-excited linear vibrating screen, in order to use a large-span vibrating motor to achieve the vibration effect of the drum-type vibrator, the method of connecting the two ends of the short-shaped vibrating motor to extend the casing is often used. Increase the span. This is a stopgap measure for no better improvement. And this way can't improve the stressed situation of motor self at all, more can't help to improve the bearing state of screen box side plate. Since there are no better improvement measures, it is difficult to break through the "bot...

AI Technical Summary

Problems solved by technology

[0005] During the parking process, because the screen box frequently passes through the transient transition resonance area, when it repeatedly passes through the low-frequency resonance area, due to the repeated alternating action of the resonance load, it is very easy to cause the cumulative damage of the screen box components under the repeated alternating vibration load

[0006] The existing screen box inclination adjustment mechanism is also unsatisfactory

[0007] In particular, the tensioning mechanism of the sieve plate or screen is very cumbersome, time-consuming and labor-intensive, and it is easy to cause "work hardening or cold hardening" on the screen during the process of repeatedly tensioning the screen, which seriously damages the screen.
