Abstract

The utility model discloses an air separation type cement powder scrap iron removing device. The air separation type cement powder scrap iron removing device comprises a separation warehouse (4) and an air blowing device, wherein the separation warehouse (4) is provided with a feed pipe (2) and a discharge pipe (6), a breathable layer plate (8) is arranged on the bottom surface of the separation warehouse (4), and the air blowing device is arranged by corresponding to the breathable layer plate (8). According to the air separation type cement powder scrap iron removing device, the specific gravity difference of broken scrap iron and cement powder is utilized, and the breathable layer plate (8) plays a role of a scrap iron supporting plate. Wind passes into the separation warehouse (4) through an air hole of the breathable layer plate (8), and the cement powder is blown up to be discharged from the discharge pipe (6). The scrap iron is left on the breathable layer plate (8), and separation of the cement powder and the scrap iron is achieved. The air separation type cement powder scrap iron removing device is simple in structure, easy to achieve and convenient to operate.

Description

A kind of winnowing type cement flour scrap iron removing device
Technical field
The utility model belongs to the separation equipment technical field, be specifically related to a kind of simple in structure, easy and simple to handle, can high-efficient cleaning except the winnowing type cement flour scrap iron removing device of iron filings in cement flour.
Background technology
In cement production process, cement grinding usually is divided into open-circuit grinding and closes the stream grinding.So-called open-circuit grinding refers to coordinate material to enter from an end of cement ball mill, by after the cement mill grinding from the other end out, go out to grind cement and directly be delivered to warehouse for finished product; Closing the stream grinding refers to coordinate material to enter from an end of cement ball mill, by after the ball mill grinding from the other end out, be delivered to powder concentrator by conveying equipment again and carry out sorting, the coarse granule material returns to cement ball mill and continues grinding, and qualified material both finished cement enters the finished cement storehouse.In the process of grinding, steel ball or forging are housed in cement ball mill, can wearing and tearing in process of lapping diminish or local fragmentation becomes bushel iron bits and sneaks in material.Closing the stream grinding system will be through the powder concentrator sorting, and the bushel iron bits can be sorted out and turn back in mill, and can not contain the bushel iron bits in finished cement, has guaranteed cement quality; But the open-circuit grinding system, these bushel iron bits can not be removed, and are mixed in finished cement, are having a strong impact on the quality of cement, particularly in the cement packing process, can threaten the safe handling of packing machine.In prior art, the method for scrap iron removing is again cement first to be entered packing machine again after bolting, but the de-ferrous effect of vibratory sieve is bad, also affects the stable operation of packing machine.For this reason, develop and a kind ofly can high-efficient cleaning produce except the stream grinding system device that contains iron filings in cement, be very important.
The utility model content
It is a kind of simple in structure, easy and simple to handle that the purpose of this utility model is to provide, can high-efficient cleaning except the winnowing type cement flour scrap iron removing device of iron filings in cement flour.
The purpose of this utility model is achieved in that and comprises separation bin and blowing device, and separation bin arranges feed pipe and discharge nozzle, and described separation bin bottom surface is ventilative laminate, the corresponding ventilative laminate setting of blowing device.
The utility model utilizes the difference in specific gravity of bushel iron bits and cement flour, adopts the selection by winnowing mode, and ventilative laminate 8 plays the double action of selection by winnowing station and iron filings bearing plate; Wind enters separation bin, and finished ground cement is blown afloat, and discharges from discharge nozzle, and iron filings are stayed on ventilative laminate, realize separating of cement flour and iron filings.The utility model is simple in structure, is easy to realize, and is easy to operate.
Description of drawings
Fig. 1 is that integrality of the present utility model is partly cutd open schematic diagram;
In figure: 1-control valve, 2-feed pipe, 3-manhole, 4-separation bin, 5-clean-out door, 6-discharge nozzle, 7-striker plate, the 8-laminate of breathing freely, 9-aeration tank, 10-airduct, 11-centrifugal blower.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but never in any form the utility model is limited, any conversion or replacement based on the utility model training centre is done all belong to protection domain of the present utility model.
As shown in Figure 1, winnowing type cement flour scrap iron removing device described in the utility model comprises separation bin 4 and blowing device, and separation bin 4 arranges feed pipe 2 and discharge nozzle 6, and described separation bin 4 bottom surfaces are ventilative laminate 8, and the corresponding ventilative laminate 8 of blowing device arranges.
As preferred embodiment:
Described blowing device comprises aeration tank 9, airduct 10, centrifugal blower 11, and the corresponding ventilative laminate 8 of aeration tank 9 arranges.This blowing device is bellows-type structure, and ventilative laminate 8 becomes a side of aeration tank 9, and ventilative laminate 8 also is equivalent to the air outlet of aeration tank 9; Ventilative laminate 8 plays the effect that disperses blowing direction, separates highly beneficial with iron filings for cement flour.
The corresponding feed pipe 2 of described separation bin 4 arranges striker plate 7.Striker plate 7 is transported to ventilative laminate 8 tops as guide plate with cement flour, enters fast separation station, can prevent that also cement flour from piling up below feed pipe 2.
Described separation bin 4 arranges clean-out door 5.Described separation bin 4 arranges manhole 3.Clean-out door 5, manhole 3 be normally off normally, and sealing device is set.
The Air permenbility of described ventilative laminate 8 is 200cm 2/ min ~ 320 cm 2/ min.
Described feed pipe 2 arranges control valve 1.
Described control valve 1 is the flap valve of opening downwards.
Described centrifugal blower 11 is the adjustable speed blower fan, with adaptation condition.
The utility model operation principle:
The utility model utilizes the difference in specific gravity of bushel iron bits and cement flour, adopts the selection by winnowing mode, and ventilative laminate 8 plays the double action of selection by winnowing station and iron filings bearing plate; Wind enters separation bin 4, and finished ground cement is blown afloat, and discharges from discharge nozzle 2, and iron filings are stayed on ventilative laminate 8, realize separating of cement flour and iron filings.
The utility model course of work:
Before removing the iron filings operation, manhole 3 and clean-out door 5 are closed; Feed pipe 2 is connected with the mill tail discharge nozzle of cement ball mill, and flap valve is the valve of opening downwards, can prevent the reverse feed pipe 2 that enters of wind; Open flap valve, cement flour enters separation bin 4, and striker plate 7 directs into ventilative laminate 8 tops with it; The centrifugal blower 11 that starts of synchronizeing with flap valve is sent into separation bin 4 with wind through ventilative laminate 8, and lighter cement flour is discharged through discharge nozzle by the wind sorting, and the heavier Impurity depositions such as iron filings realize that on the surface of ventilative laminate 8 cement flour and the efficient of iron filings separate.
Characteristics of the present utility model:
1, the ingenious weight difference that utilizes material and impurity of the utility model, realize quick sorting with wind;
2, the utility model is simple in structure, is easy to realize, and is easy to operate.
