Description

The mechanically driver type material separator

The utility model relates to a kind of mechanically driver type material separator, is specially adapted to the sorting of granularity lump coal more than 25 millimeters, also can be used for the discharge refuse or the sorting piece cleaned coal of coal preparation plant's piece raw coal.

Existing material separator mainly is made up of parts such as casing, lifting wheel, moving sieve and chutes, on moving sieve fluid pressure drive device is housed.When carrying out the material sorting process, fluid pressure drive device drives moving sieve and makes upper and lower periodic vibration.When the granularmetric composition more complicated of material, its separating effect is relatively poor, particularly because the regular care and maintenance of hydraulic system in the complexity of the hydraulic system of machine mechanism own and the work has brought a lot of inconvenience to production operation.The present hydraulic drive type separator that uses, its drive system is a hydraulic structure, its moving sieve frequency, moving sieve amplitude, that the upper and lower movement velocity of moving sieve is straight line is adjustable.But because automatically controlled, the hydraulic structure more complicated of this separator, its technical performance of installing, operate, safeguarding is had relatively high expectations, and also very strict to the working condition requirement, particularly manufacturing cost is also higher, so influence its wide popularization and application.

The purpose of this utility model provides a kind of mechanically driver type material separator, and it has overcome the shortcoming that prior art exists, and has reduced manufacturing cost, has simplified operation, maintenance program, has improved reliability of operation.

The purpose of this utility model is achieved in that this device comprises casing and assembles the lifting wheel on it, moving sieve, chute and drive unit, wherein the crankwheel of driveshaft end joins by crank and swing link end part in the mechanical actuation device, the adjusting suspension ring one end activity that is hinged on the moving sieve is assembled on the fork arm, and the downflow weir place of moving sieve discharge end is provided with the buoy gate.

Because adopting mechanical actuation device to drive moving sieve vibration, the utility model carries out sorting, thus more simple in structure than fluid pressure drive device, reduced manufacturing cost, simplified operation sequence, be convenient to safeguard.The adjusting of moving sieve amplitude utilizes handwheel to carry out manual control adjustment, and is easy to operate, is easy to safeguard, improved reliability of operation.Moving in addition sieve discharge end is provided with the buoy gate, can make by behind the material gravity segregation of sorting, by flowing into above the downflow weir in the light silo of lifting wheel, lower floor's heavy material flows into below downflow weir in the lifting wheel weight hopper through the buoy of buoy gate with upper materials.Thereby effectively guarantee accurately to be flowed into separately in the hopper, further improve this device sorting reliability of operation by sorting material.

The utility model is described in further detail below in conjunction with accompanying drawing.

Describe concrete structure of the present utility model in detail according to Fig. 1-5.This device comprises that casing 1, the lifting wheel that have light silo 5 and weight hopper 6, the discharge end downflow weir place of assembling on the casing 1 are provided with the moving sieve 8 of buoy gate 2, place light material chute 3, heavy material chute 4 and mechanical actuation device 7 light, weight hopper corresponding site respectively.This mechanical actuation device 7 comprises parts such as motor 17, belt drive unit 15, decelerator 14, a pair of exposed gear 20,12, driving shaft 19, the crankwheel 11 that is installed in driving shaft 19 ends, crank 10, fork 13.Wherein crankwheel 11 joins by crank 10 and fork 13 ends.Fork 13 activity on the fork arm of axle 9 swings is assembled with regulates suspension ring 18, is hinged on the slide block 21 of handwheel 16 controls.Regulate the top that suspension ring 18 other ends are hinged on moving sieve 8.Come mobile suspension ring 18 by the position that handwheel 16 is adjusted slide block 21, to realize the step-less adjustment of moving sieve 8 amplitudes.The diameter of adjusting the large and small belt pulley in the belt drive unit 15 can drive fork 13 to regulate moving sieve 8 motion frequencies by the crankwheel on the driving shaft 9 11 than (speed ratio).The buoy 22 of buoy gate 2 is connected with the lever 24 that adjustable counter balance 26 is housed by pull bar 23.Adjust the position of counterweight 26 on lever 24, lever 24 is rotated around its axle 25, drive pull bar 24 and determine the position of buoy 22, to adapt to by the needs of sorting material different grain size layering shunting at moving sieve discharge end downflow weir place.

During operation,, adjust the belt drive unit speed ratio, regulate the position of suspension ring 18, determine the frequency and the amplitude of moving sieve 8, adjust counterweight 26 so that the unlatching of buoy gate 2, adapt to the needs of the proportion of different material in advance according to by the requirement of sorting material.Start the moving sieve 8 of drive unit 7 drives and carry out separation operation.Behind the varigrained material layering, be in the light material in upper strata flows into lifting wheel above downflow weir the light silo 5, lower floor's heavy material flows into the weight hopper 6 of lifting wheel below downflow weir through the buoy 22 of buoy gate 2.Along with the rotation of lifting wheel, by light, the heavy material of sorting pour into respectively gently, 3,4 discharges of heavy material chute, finish the sorting task.
