Background technique：typically by the vibrating mechanism vibrating screen, screen box, the spring, and the support drive means, etc., because it has a circular vibration locus is referred to as circular vibrating screen. Of the bin vibrating screen sieve loose layer of material, and thrown away from the screen surface, so that the fine fraction is discharged through the layers and fall through the sieve, and the granules stuck in a vibration sieve species, in addition to the screening effect In addition, the material and forward movement. The main disadvantage in the presence of a conventional design: First, medium-sized circular vibrating screen is single-spindle, two bearing or bearing structure, such devices generally use large type bearings, and the carrier has reached its limit speed, greatly reduced reliability of the apparatus; second, using multiple motor housing stationary, since no anti-vibration apparatus side, start, stop during large amplitude resonance region, an elongated pulling belt, detract from the life of the belt, on the screen box also cause damage. From the above reasons, resulting in low efficiency of existing vibration equipment, and often downtime
Now design engineer of pk machingery has provided a circular vibrating screen, simple structure, and the amplitude, high frequency, the working efficiency can be increased 50% or more.
First to solve the problems is: A circular vibrating screen, a motor drive means, vibrating means, screen box, and the damper bearing bodies, the sieve box via the damper means disposed on the support, the vibrating mechanism consists of two interconnected through synchronizer composition spindle, two spindles are connected to the motor drive corresponding to each of the main shaft is an eccentric shaft, the main shaft is also provided an eccentric mass, eccentric mass through the sieve box is provided on the spindle.
The motor drive means is constituted by belts, motors, panel and the chassis, the motor panel by a connecting shaft provided on the base, disposed on the panel connected to the spindle via a belt, between the panel and the base is also provided with damper spring.
The beneficial effects of the circular vibrating screen are:
Our design is since the vibration mechanism used for double-spindle structure, timing belt synchronous rotation, simple structure, reliable, easy to maintain, sufficient vibration force, amplitude, high frequency, high output to ensure high efficiency, while greatly reducing the weight of the equipment.
the shaker large capacity, high efficiency, the work efficiency can be increased 50% or more.
the Sketch of circular vibrating screen working process:
A circular vibrating screen by the support plate into close contact with the screen box damper mechanism the damper mechanism described herein may be employed such as a spring elastic element. In the vibration mechanism the vibrating mechanism and the motor drive apparatus is connected to the screen box is provided, the motor drive device can be kinetic energy to the vibrating mechanism , the vibration means converting kinetic locus circle of the vibration is transmitted to the screen box , shaker tank so that the material layer of loose mesh surface, and thrown away from the screen, so that the fine fraction is discharged through the layers and fall through the sieve, and the granules stuck in the vibration screen mesh species out, In addition to the screening effect, and the forward movement of materials.
the motorthrough the power transmission belt is transmitted to the main shaft of the vibration mechanism, the vibration mechanism is a two-spindle structure, the two spindles through synchronizer interconnected components. Two spindles arranged in parallel, the same end of each spindle drive motor, respectively independently connected, at its other end through synchronizer is connected to the spindle so that the two synchronous movement, the main shaft as an eccentric shaft, each the upper spindle provided with two eccentric, screen box is provided by four eccentric mass on the two spindles. A vibration generating mechanism and through which the eccentric shaft eccentric mass rotational excitation force the screening structure oven for a circular locus of the vibration, the compositions may take the timing belt and the timing pulley synchronizer, since the vibration mechanism is a two-spindle structure , timing belt synchronous rotation, simple structure, reliable, easy to maintain, sufficient vibration force, amplitude, high frequency, to ensure a large output, high efficiency, while greatly reducing the weight, cost savings, is a species energy efficient, practical, large circular vibrating screen.
Our disgin the sieve box is reinforced by a plurality of side plate parts of the reinforcing plate angle steel vibrating mechanism, to increase the strength of the side plate, the side plate itself IOmm thickness, i.e. to ensure the strength and greatly reduces the cost. Tank above the sieve has a plurality of longitudinal beams and support plate and a support angle bars, a support plate and a support angle layered with screen, screen bolts through the elongated platen and the T-head, a simple structure, i.e. only one person the installation can be completed platen, saving space, thereby reducing the distance layer, reducing the height of the screen box, to save costs.
