Description
The three-axis elliptical horizontal screen is mainly composed of screen box, screen mesh, vibrator, damping spring device, bottom frame and so on. Using cylindrical eccentric shaft exciter and deflector to adjust the amplitude, the vibrator is installed on the side plate of the screen box, and is driven by the motor through the triangle belt to rotate, generating centrifugal inertia force, forcing the screen box to vibrate. The side plate of the screen machine is made of high quality steel plate, and the side plate is connected with the beam and the base of the exciter by high strength bolts or ring groove rivets.
1, Screen box: by several kinds of thickness of different steel plate welding, with a certain strength and stiffness, is the main component of the screen machine;
2, Screen frame: made of pine or small deformation of wood, mainly used to keep the screen flat, to achieve normal screening;
3, Screen: there are low carbon steel, brass, bronze, stainless steel wire and other several kinds of screen;
4, Vibration motor: (use and maintenance methods refer to the vibration motor instruction manual);
5, Motor pedestal: installation of vibration motor, before the use of the connection screw must be tightened, especially three days before the trial of the new screen machine, must be repeatedly tightened, so as to avoid loosening caused by accidents;
6, Damping spring: prevent vibration to the ground, while supporting the full weight of the screen box, installation, the spring must be perpendicular to the ground;
7, The support: consists of four pillars and two channels, supporting the screen box, the installation of the pillar must be perpendicular to the ground, the two pillars below the channel should be parallel to each other.
Performance Advantages
- 1、the use of eccentric block as a vibration source, simple structure, reliable, easy maintenance. Large exciting force, high screening efficiency.
- 2、 the synchronizer is a specially designed gear box, which makes the three groups of eccentric blocks on the three-axis vibrator rotate synchronously according to the designed phase Angle difference, and the elliptical motion track formed by the exciting force generated by the three groups of eccentric blocks is accurate and reliable through the involute gear transmission, which stabilizes the working state of the vibrating screen. The synchronizer adopts a symmetrical structure with one axis input and three axes output, which is easy to install and use.
- 3、 the connection between the side plate and the strengthening plate and the steel pipe beam are all riveted with special high-strength ring groove rivet for vibrating screen. The rivet has high shear strength, anti-vibration, and does not move riveting to avoid the side plate cracking and other accidents caused by welding defects.
- 4、 the optimized design of elastic components, reduce the foundation load, with long service life, over the resonance area stable, low noise advantages (according to the use of "metal coil spring" or "composite spring").
- 5、 the middle and both sides of the screen tightening structure, the screen vibration damping rubber strip Settings make the effective service life of the screen longer.
- 6、 the motor and the exciter are connected by flexible coupling, so that the torque transmission is not transmitted by axial force, so that the operation of the screen machine is more stable.
- 7、 the use of low alloy structure steel plate (Q345C), so that the equipment in the cold area of -40℃ can still ensure its overall stiffness.
Working Principle
TSK series three-axis horizontal screen is a screening equipment with three-axis eccentric exciter as the excitation source, elastomeric spring as the elastic element and screen box exciter as the moving part. The three axes of the vibrator are equipped with counterweights of equal eccentric mass and the same eccentric radius. The power is transmitted by the motor through the belt to the drive shaft, and then driven by the gear with a speed ratio of 1, so that the three shafts rotate at the same speed, thus generating an exciting force, so that the screen box is forced to make continuous elliptical motion. The material is driven by this movement, and continuously throws in the circular direction on the horizontal screen surface, and moves forward while throwing up the loose stratification, completing the process of particle size classification and forward transportation repeatedly.More Pictures
