Description

Circular airflow screening machine for powder material
Technical field:
The present invention relates to a kind ofly solid material is diffused in the equipment that carries out sorting in the air-flow, particularly circular airflow screening machine for powder material with air-flow.
Background technology:
China Patent No. provides a kind of air-flow sieve powder technology for 912023341,012735752, all is better than the vibrosieve technology for its screening efficiency of screening of powder, unit-hour output, screening fineness etc., thereby has obtained using widely.Yet this air flow powder sieving machine exposes following problem in use for many years: at first be that the gentle powder of feeding mixes inequality, when the powder of spout for a long time, the gas of introducing from areole reduces on the contrary, the powder atomizing is insufficient, even powder one-tenth is block, and more seriously block powder breaks up screen cloth; Next is that screen cloth damages, and produces because material has caking in roasting, often has hard objects (screw, pad, cement block etc.) to sneak in the material, the above-mentioned not material piece of atomizing, screen cloth is damaged, cause stopping production, change screen cloth, the frequency of damaging the screen cloth stopping production for above-mentioned reasons is higher, ordinary circumstance is changed screen cloth can be with a class, and the longest also have only 2-3 days, and a class need change 2-3 screen cloth sometimes, not only strengthened cost, more seriously influence is produced.Application number is 200610017573.0 the disclosed technical scheme of a kind of full circulation air flow powder sieving machine; its powder atomizing is abundant, sieve powder efficient height; screen life-span is longer; but owing on air inlet pipeline, be provided with disperser; hard objects in the powder (screw, cement block) can be separated, but the cone centrifugation in this diffuser casing is bad for the separation than grain in the powder; and these grains can puncture screen cloth, and this apparatus structure complexity, volume are big.
Summary of the invention:
The technical issues that need to address of the present invention provide a kind of screening efficiency height, the long and low air flow powder sieving machine of cost simple in structure of screen life-span.Technical scheme of the present invention is, circular airflow screening machine for powder material, comprise blower fan, feeding machine, screening machine, cyclone separator, it is characterized in that: described feeding machine is located on the air inlet pipeline between blower fan and the screening machine, the top and the bottom of the air inlet pipe of screening machine top are arc, in this arc air inlet pipe, be provided with the arc coarse strainer, the left side of this coarse strainer, right two ends are connected with top board with the base plate of described arc air inlet pipe respectively, its rear and front end is connected with the front and back sidewall of arc air inlet pipe respectively, bottom in the arc air inlet pipe of arc coarse strainer left end is provided with out the impurity pipe, the middle part of one baffle plate is one side walls hinged with the mouth of pipe that goes out the impurity pipe, is provided with a weight at the external end head of this baffle plate; Be provided with outlet pipe between the gas outlet of the air inlet of described cyclone separator and screening machine bottom, the upper end of rubber slab is connected on the plate of cyclone separator storage bin discharging mouth of pipe top.Blade in the screening machine is distributed on the wind wheel core barrel of sealing.On the air inlet pipeline between blower fan and the feeding machine, be provided with loose gas cloth bag and air-flow plate successively.The present invention has the screening efficiency height compared with the prior art, screen life-span is long and the low remarkable advantage of cost simple in structure.
Description of drawings:
Fig. 1 is the structural representation of air flow powder sieving machine of the present invention, and Fig. 2 is the A-A profile of Fig. 1.
The specific embodiment:
In conjunction with above accompanying drawing the present invention is elaborated, for the cone that overcomes diffuser casing in the prior art to the not good deficiency of less grit separating effect in the powder, through testing to have adopted coarse net 14 is set in the arc air inlet pipe, when grit in the interception powder and foreign material, can be with its interception back from 11 mouthfuls of discharges of impurities removal matter pipe, improve screening efficiency, prolonged the life-span of screen cloth 7.For this reason, the present invention is provided with feeding machine 5 on the pipeline between the air inlet at the outlet of blower fan 1 and screening machine 6 tops, tolerance adjustable plate 3 is located on the pipeline between feeding machine and the blower fan, spool being connected on the outer handle 4 of pipe and the adjustable plate 3, the end of this air inlet pipeline promptly is an arc air inlet pipe 15 above screening machine, the rear and front end of coarse strainer 14 is connected with the front and back sidewall of arc air inlet pipe 15 respectively, end is connected with upper wall with the lower wall of above-mentioned curved pipe respectively about it, be provided with the wind wheel core tube 9 of sealing in the screening machine, blade 8 is distributed on the circumference of core tube, wind wheel is provided with filter screen 7 outward, is provided with storage quarrel storehouse 10 in the bottom of screening machine.Between the air inlet of the gas outlet of screening machine bottom and cyclone separator 17, be provided with outlet pipe 16, storage bin is arranged at the bottom of cyclone separator, discharge nozzle is arranged at the storage bin bottom, the top of rubber slab is connected with the plate on discharge nozzle top, during screening machine work, storage bin is a negative pressure, and rubber slab seals up the discharging mouth of pipe.Be provided with out impurity pipe 11 in the curved pipe of coarse strainer left end bottom, the middle part of baffle plate 12 has one with to go out impurity mouth of pipe wall hinged, and the overhanging end of baffle plate has a weight 13.For simplified structure, the bin outlet of feeding machine, muck removal mouth and cyclone separator is not established the device of holding one's breath, thereby is provided with the gas cloth bag 18 that looses on the air inlet pipeline 2 of fan outlet, is used for gas unnecessary in the system is released.Between the air inlet of the gas outlet at cyclone separator top and blower fan, be provided with escape pipe 19.
