Description
Technical field
The utility model relates to the fine grading sieve, is particularly useful for the classification of the difficult screening of colliery particulate material, also is applicable to the screening operation of industries such as building materials, metallurgy, chemical industry, electric power.
Background technology
At present, the equipment that is used for the classification of particulate difficult screened material is varied, and the most frequently used is vibratory sieve.Practice shows that for fine, because viscosity is bigger, vibratory sieve list amplitude is between 3～5mm, and material more easily blocks up sieve aperture, and screening efficiency is low, and treating capacity is little.And the vibrator of traditional vibratory sieve all installs on the biside plate of screen box, and screen box participates in vibration.Its shortcoming is that mechanical strength is relatively poor, and it is big that screen box participates in the vibration power consumption, maintenance difficult.
Summary of the invention
Technical problem: the purpose of this utility model provides a kind of rational in infrastructure, the screening efficiency height, and treating capacity is big, the fine grading sieve that dismounting is easy to maintenance.
Technical scheme: the utility model fine grading sieve, it comprises screen box, sieve plate, drive motors, frame and shock-absorbing spring, both sides are provided with a formula vibrator along the logistics direction outside screen box, two side seat type vibrators are seated on the exciting framework, and the exciting framework is located at the screen box bottom, and the exciting framework is provided with shock-absorbing spring along the two ends of logistics direction, shock-absorbing spring is located on the frame, drive motors be located at the seat formula vibrator coaxial mounted support that is fixed on the frame on.
The utility model fine grading sieve, described seat formula vibrator by eccentric block, be fixed in the bearing seat on the exciting framework, bearing and the power transmission shaft that is located in the bearing seat constitutes, the eccentric block symmetry is located on the power transmission shaft that stretches out the pedestal both sides, seat formula vibrator matches with the number of screen box, can be one group, also can be two groups or three groups; The channel-section steel that described exciting framework is oppositely arranged by two concave surfaces and form with the channel-section steel groove I-steel that is connected as a single entity that is interlocked also can be connected to form by square tube or seamless pipe.。
Beneficial effect: the utility model fine grading sieve, employing both sides outside screen box are provided with a formula vibrator along the logistics direction, two side seat type vibrators are seated on the exciting framework, the exciting framework adopts the shaped steel riveted joint to form, solved the structure difficult problem of sieving machine large span, screen box design width can be brought up to more than 8 meters by 2 meters, and whole compass screen surface vibration is steady, and noise is significantly less than traditional vibratory sieve.Vibratory sieve can be made up of multiple-unit, thereby overall structure is more simplified, and the process-cycle shortens greatly, and fault is few, and the production efficiency height has the feature of environmental protection, effectively reduces the driving power of complete machine.Under same units treating capacity, equal sieving area, strong vibrating screen is compared with the driving power of traditional vibratory sieve, can save energy more than 50%, be applicable to colliery, building materials, metallurgy, chemical industry, the screening operation of industries such as electric power, its structure optimization, be convenient to install maintenance, satisfy the stiffness requirement fully, alleviate greatly and join the weight of shaking, simplified manufacturing process, process-cycle is short, sieve box side plate fracture, polarization phenomena can not take place, and the service life of equipment height has practicality widely.
