Abstract
The utility model relates to a particle sorting machine, which is mainly composed of a machine shell, an original dust inlet pipe, a guide plate regulator, and a volute. A fine dust outlet and a thick dust outlet are arranged on the machine shell. The original dust inlet pipe is composed of a straight pipe and a bending pipe. An original dust inlet path of the bending pipe and a flow guiding path in the machine shell form an S shape, and the curvature of the bending pipe is 180 DEG. The inside of the fine dust outlet is provided with a circular cylinder for blocking the flowing of thick particles. Thus, the thick particles on the inner side of the flow guiding plate are crashed with outer side fine particles on an outlet of the flow guiding plate, the speed of the fine particles is reduced, and the sorting rate of the sorting machine is effectively raised.
Description
The utility model is a kind of particle-size distributor.
At present, particle-size distributor is mainly used in the comprehensive utilization of thermal power plant flyash, it is mainly by casing, former grey ash inlet tube, deflector, the deflector adjusting device, spiral case is formed, casing is provided with thin ash outlet and cinder outlet and secondary air mouth, spiral case is located at the thin ash outlet of casing, adopt the principle of centrifugal eddy current, solid particle is carried out particle size sorting, former grey ash inlet tube is single straight tube shape, former ash directly tangentially enters in the separator through straight tube, water conservancy diversion through deflector, the cinder of initial gross separation enters the outside of deflector, and thin ash enters the inboard of deflector, and thin ash concentrates on the thin grey chamber of deflector inboard, at last, thin ash outlet through the casing middle part is discharged by the outlet on the spiral case, and cinder is discharged through the cinder outlet of bottom of shell, because former ash is directly tangentially to enter by straight tube to carry out water conservancy diversion in the separator, the cinder that mixes in the thin ash is not easily separated at the deflector inner space, has reduced the sorting index of separator.
The purpose of this utility model be to provide a kind of simple in structure, cost is low, can effectively improve the particle-size distributor of sorting index.
The utility model is achieved in that particle-size distributor mainly is made up of casing, former grey ash inlet tube, deflector, deflector adjusting device, spiral case, casing is provided with thin ash outlet and cinder outlet, spiral case is located at the thin ash outlet of casing, described former grey ash inlet tube is to be made of straight tube and first sorting bend pipe, former grey import is located on the straight tube, just the sorting winding pipe exit is connected to the water conservancy diversion import on the casing, and the water conservancy diversion path that the former ash of first sorting bend pipe advances in grey path and the casing constitutes similar S shape.
The described camber of sorting bend pipe just can be 180 °.
Described straight tube can downward-slopingly be provided with.
The thin grey outlet of described casing inside can be provided with a cylinder that stops that coarse granule flows out.
The utility model is owing to be designed to straight tube and first sorting bend pipe with former grey ash inlet tube, the water conservancy diversion path that the former ash of bend pipe advances in grey path and the casing constitutes similar S shape, the coarse granule of deflector inboard can be bumped with the fine grained in the deflector outside when breaking away from deflector, fine grain speed is reduced, under suction function, discharge, effectively improved the sorting index of separator through thin ash outlet.
Below in conjunction with embodiment the utility model is described in detail:
Fig. 1 is the distribution map of thickness particle in the utility model separator;
Fig. 2 is the structural representation of facing of the utility model separator;
Fig. 3 is the side-looking structural representation of the utility model separator.
With reference to figure 1; former grey ash inlet tube is made of straight tube 1 and first sorting bend pipe 2; bend pipe path and water conservancy diversion path are the S shape; former ash is introduced into straight tube 1; after bend pipe 2 first sortings; by the deflector 4 in the casing 3; the coarse granule air-flow of initial gross separation enters the inboard of a deflector 4, and fine grained enters the outside of a deflector 4, and just the coarse granule air-flow is in the flows inside of a deflector 4; fine grained is in the flows outside of a deflector 4; because the particle weight difference, the coarse granule of flows inside obtains bigger centrifugal force, after air communication is crossed deflector 4; under action of centrifugal force; inboard coarse granule air-flow certainly will flow laterally, forms the cross flow one of thickness particle, bumps between the particle; the coarse granule velocity variations that quality is bigger is little; the less fine grained speed of quality can obviously reduce, and fine grained is discharged through thin ash outlet under suction function; coarse granule is thrown toward the cinder chamber of separator downside under action of centrifugal force, discharge through the cinder outlet.
With reference to figure 2, Fig. 3, particle-size distributor is mainly by casing 3, former grey ash inlet tube, a deflector 4, secondary deflector 5, deflector adjusting device 6,7, spiral case 8 is formed, casing 3 is provided with thin ash outlet 9 and cinder outlet 10, spiral case 8 is located at the thin ash outlet 9 of casing 3, described former grey ash inlet tube is to be made of straight tube 1 and first sorting bend pipe 2, former grey import is located on the straight tube 1, sorting bend pipe 2 outlets just are connected to water conservancy diversion import on the casing 3 by bolt, sorting bend pipe 2 imports just are connected to the outlet of straight tube 1 by bolt, the water conservancy diversion path that the former ash of first sorting bend pipe 2 advances in grey path and the casing constitutes similar S shape, just the camber of sorting bend pipe 2 is 180 °, helping a deflector 4 separates the thickness particle better, straight tube 1 is downward-sloping, the coarse granule of deflector 4 inboards and outside fine grained produce collision in the outlet of deflector 4, adjusting device 6,7 can be respectively to deflector 4,5 regulate, and Fig. 1 has provided deflector 4,5 adjusting track.In addition, according to aerodynamic principle, place near the separator wall, because the influence of medium viscosity, can there be boundary-layer, gas flow rate in the boundary-layer is starkly lower than other positions, that is to say, the part coarse granule can not get the influence that enough centrifugal force overcomes negative pressure, and is brought into the fine grained air-flow, has reduced classification efficiency, for overcoming the influence of this respect, thin ash outlet 9 in casing 3 inside is provided with a cylinder 15 that can stop that coarse granule flows out, and this cylinder of setting up 15 can improve 3-5% with the classification rate, and described cylinder 15 is connected the inboard of thin ash outlet by flange.
For further improving sorting index, above cinder outlet 10, be provided with secondary air mouth 11, the enclosure wall 12 relative with secondary air mouth 11 is circular arc, casing inner wall in deflector 4 exits forms corresponding tip-angled shape, become mechanical subregion by original secondary air nature subregion, the flyash passage that extended has reduced flyash washing away the casing internal layer effectively, when improving sorting index, further prolonged the service life of separator.
In order to improve the anti-wear performance of separator, increase the service life, deflector 4,5 and casing 3 inner-wall sprayings have the metallurgical powder coating.In order to improve intensity, the casing outside of tip-angled shape part is provided with stiffener 13, and in order to overhaul conveniently, spiral case 8 is provided with cover plate 14.
