Abstract
The present invention discloses a full circulation air flow powder sieving machine which relates to separation technique. The aim of the present invention is to design a full circulation air flow powder sieving machine which is an air flow powder sieving machine with sufficient powder material atomization, long service life of sieve and high sieving efficiency. The present invention has the technical scheme that the novel full circulation air flow powder sieving machine comprises an airflow sieve and a cyclone separator; a discharge pipe of a gas check valve is communicated with a feed air pipe of which both ends are respectively connected with an air inlet at the upper part of the airflow sieve and a discharge pipe of a feeding blower; both ends of a suction air pipe are respectively connected with a fine powder outlet of the airflow sieve and an air inlet of the cyclone separator; an air outlet of the cyclone separator is communicated with an air inlet of the feeding blower; gas check valves are respectively arranged on a discharge port of the cyclone separator and a coarse powder outlet at the bottom of the airflow sieve. A diffusion chamber is arranged on the feeding air pipe between the gas check valves and the airflow sieve; a gas check valve is arranged on a discharge port at the bottom of the diffusion chamber. The present invention is used for sieving the powder material.
Description
Technical field:
The present invention relates to a kind of isolation technics, particularly a kind of airflow shifting machine.
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.
Summary of the invention:
The objective of the invention is to design a kind of full circulation air flow powder sieving machine, the atomizing of its powder is abundant, and another object of the present invention is the long full circulation air flow powder sieving machine of a kind of screen life-span of design; A further object of the present invention is the high air flow powder sieving machine of a kind of screening efficiency of design.Technical scheme of the present invention is, a kind of full circulation air flow powder sieving machine, comprise air-flow sieve and cyclone separator, it is characterized in that: the discharge nozzle of gas check valve is connected with the feeding airduct, the two ends of this feeding airduct are connected with the air inlet on air-flow sieve top and the discharge pipe of feeding fan respectively, the two ends of suction airduct are connected with the air inlet of cyclone separator with the fine powder outlet of air-flow sieve respectively, the air outlet of cyclone separator and the air inlet of feeding fan are connected, in the meal outlet of the discharging opening of cyclone separator and air-flow sieve bottom, respectively be provided with gas check valve, be provided with a diffuser casing on the feeding airduct between gas check valve and the air-flow sieve, the discharging opening of diffuser casing bottom is provided with gas check valve.Be provided with the sorting cone in diffuser casing, this sorting cone is fixed on two poles that are connected mutually with clip, and upward the air outlet with feed pipe is relative, and bolt is through in the otic placode hole at clip two ends.The present invention is owing to place the discharging opening of drawing-in device the discharge pipe of blower fan, on the airduct between blower fan and the sieving machine, be provided with anemostat and sorting awl, thereby the present invention has powder compared with the prior art and atomizes, the remarkable advantage that screening efficiency height and screen life-span are long.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
In conjunction with above-mentioned accompanying drawing the present invention is elaborated, the discharging opening of gas check valve 2 is communicated with feeding airduct 6 between feeding fan 1 air outlet and the sieving machine charging aperture 9, drawing the two ends of expecting airduct 5 is communicated with the air inlet of outlet 11 of sieving machine fine powder and cyclone separator 4 respectively, the meal outlet of this cyclone separator is provided with gas check valve 3, the last air outlet of cyclone separator is communicated with the air inlet of feeding fan 1, exports 13 places at the sieving machine meal and is provided with gas check valve 12.This employing blower fan feed mechanism, it is very abundant that its powder of sending into sieving machine mixes with gas, thereby its screening efficiency is greatly improved.On feeding airduct 6, establish a diffuser casing 7, the powder caking that has produced when being mingled with hard objects such as metal, cement or roasting in the powder can sedimentation in diffuser casing drops on discharges through gas check valve in the diffuser casing bottom discharge cone, thereby has avoided above-mentioned thing piece to break up screen cloth 10 in sieving machine.Also a sorting cone 8 can be set in this diffuser casing, on two poles that this sorting cone is fixed on clip is connected mutually, bolt is through in the hole of clip otic placode, the sorting cone is relative with feeding airduct mouth, the sorting cone has two effects, the one, the thing piece in the powder can be deposited to the bottom of diffuser casing, the powder caking can also be smashed into powder simultaneously, enter the sieving machine screening, further improve screening efficiency, second effect is by the tapering size of adjusting sorting cone and the distance between cone and the airduct mouth, powder sorting settling greater than sieve screen apertures can be discharged from gas check valve at the bottom of diffuser casing, thereby the screening efficiency of air flow powder sieving machine of the present invention is got a greater increase.
