Description

Material sorting device

Technical field

The utility model relates to a kind of raw meal particle size sorting unit, specifically is that a kind of wind-force that utilizes is to the thickness particle of material or the device that has the particle of difference in specific gravity to carry out sorting.

Background technology

Publication " Sichuan cement " fourth phase in 1998 (P40) has disclosed a kind of " V-type powder concentrator " technology, and its structure is seen Fig. 1.This V-type powder concentrator comprises housing 1 ', charging aperture 2 ' lower housing portion seedy outlet 3 ' is arranged at housing top, one side of housing has air inlet 4 ', opposite side has fine particle outlet 5 ', the V-arrangement screen mechanism 7 that has tilting screen 6 to constitute in the housing by plurality of V shape, between the left side plate of V-arrangement screen mechanism 7 passage is arranged, it is the branch constituency 8 of thickness particle, suitable for reading and the charging aperture 2 ' in branch constituency 8 communicates, the end opening in branch constituency 8 communicates with coarse grain discharging opening 3 ', between every two adjacent screens gas channel 9 is arranged in the V-arrangement screen mechanism 7, gas channel 9 air intake vents communicate with air inlet 4 ', gas channel 9 air outlets communicate with branch constituency 8, and communicate with fine particle outlet 5 ' by the passage between the V-arrangement screen mechanism 7 left side dividing plates.

The operation process of this V-type powder concentrator is: the bulk powder material is fallen within the branch constituency 8 between V-arrangement screen mechanism 7 left side plates by charging aperture 2 ', air-flow with blast and wind speed acts on the material of whereabouts through gas channel 9, make the bulk powder material come and go the bump left side plate in in-house minute in 8 dropping process of constituency along the V-arrangement screen, the bulk powder material is broken up, coarse granule falls because of its gravity effect and is discharged by coarse grain outlet 3 ', fine particle promptly flows to fine particle outlet 5 ' with air-flow along the gas channel between V-arrangement screen mechanism 7 left plates and discharges, and promptly realizes the sorting with the thickness particle of breaing up to the bulk powder material.It is simpler to be somebody's turn to do " V-type powder concentrator " structure, can successfully realize the breaing up of bulk powder material, sorting, but the deficiency that the thickness grain sorting that is used for non-bulk powder material exists is: the one, and the left plate of V-arrangement screen mechanism 7 can increase gas-flow resistance, causes the supply air system power consumption bigger; The 2nd, with the branch constituency of the passage between V-arrangement screen mechanism 7 left side plates as coarse granule and fine particle, its sorting space is too small, and coarse granule and fine particle are difficult to obtain abundant sorting; The 3rd, the member of V-arrangement screen mechanism 7 is subjected to the repeated stock of air-flow and granulate mixture, and the member wearing and tearing are fragile greatly; The 4th, because the space in thickness grain sorting district 8 is little, the efficiency of separation is low, influences production capacity.

Summary of the invention

The purpose of this utility model provides a kind of material sorting device, and this sorting unit can make the coarse granule of powder material and fine particle be able to abundant sorting, improves the efficiency of separation, reduces energy consumption, and can effectively reduce the wearing and tearing of granulate mixture to internals.

The technical solution of the utility model, referring to Fig. 2, comprise housing 1, charging aperture 2 is arranged at housing top, lower housing portion seedy outlet 3, one side of housing has air inlet 4, opposite side has fine particle outlet 5, improved structure is: be provided with the laminar flow plate mechanism 11 that is made of some dividing plates 10 in the housing, the two ends of dividing plate 10 are connected to the biside plate of housing 1, and described laminar flow plate mechanism 11 is divided into two chambers with the inner chamber of housing 1, and the one side is an air compartment 12, opposite side is a separation chamber 13, charging aperture 2 communicates with separation chamber 13, between the two every adjacent dividing plates in the laminar flow plate mechanism 11 gas channel 14 is arranged, and the air intake vent of gas channel 14 communicates with air compartment 12 and air inlet 4, the air outlet of gas channel 14 communicates with separation chamber 13, and separation chamber 13 communicates with coarse grain outlet 3 and fine particle outlet 5.

Operation process of the present utility model is; material enters separation chamber 13 by charging aperture 2; air-flow with blast and wind speed is via the gas channel between the dividing plate 10 14; form laminar flow the powder material in the dropping process is carried out abundant sorting in the whole space of air compartment 12; coarse granule or heavy particle fall because of its gravity effect and are discharged by coarse grain discharging opening 3, and the particle that fine particle or proportion are little is discharged by fine particle outlet 5 with air-flow.Use again such as this type of device of cyclone separation device after the particle that fine particle or proportion are little is discharged with air-flow and carry out powder, gas separation.

The characteristics that the utility model had are:

1, because the dividing plate 10 of the utility model laminar flow plate mechanism 11 is the one-board structure, saved the left plate of background technology " V " shape screen, thereby simplify the structure further, low material consumption falls, especially reduced the resistance of air-flow, need not big wind speed and collide and break up lump material, effectively reduce energy consumption with big air quantity;

2, formed separation chamber 13 by after the cutting apart of 11 pairs of housing inner chambers of laminar flow plate mechanism, divide constituency with the passage between the left side plate of " V " shape screen mechanism as material than background technology, increased the space of material sorting, make material sorting fully, improve separating effect, help improving the efficiency of separation and production capacity;

3, in service, because of no material collides the process of breaing up, device endoparticle collision opportunity reduces, in addition, because no dividing plate obstacle in the branch favored area of separation chamber 13, so steady air current and the required gas pressure that provides can reduce, and can reduce the wearing and tearing of bulking block thus.

4, the enforcement structure that provides by Fig. 4, every adjacent two dividing plates 10 the vertical direction towards the plate end of separation chamber 13 have a numerical value greater than zero apart from S, all dividing plates 10 that are laminar flow plate mechanism 11 constitute a stairstepping at the plate end towards separation chamber 13, make material fall step by step along the cascaded surface that dividing plate constitutes, the one, can increase stroke or path that material falls, the 2nd, when material drops down onto down on one deck dividing plate by the upper strata dividing plate, the effect that the powder material of not finishing temporarily sorting is had certain sub-material again, impel material to become equally distributed state to fall, both all help further improving separating effect.

Below in conjunction with drawings and Examples the utility model is further specified.
