Abstract
The utility model relates to a deep-layer cyclone feed device, wherein a distributing barrel is fixed on a deflector through a bracing frame, wherein the deflector is in a circular ring shaped, the lower portion of a screen plate in the distributing barrel is provided with a chocked flow plate, and the chocked flow plate is fixed on the inner wall of the distributing barrel in an inclined circular ring shaped whose inner ring is downwards, and a plurality of choked flow refracting plates which are evenly arranged in a radiating shape is vertically fixed on the deflector. The deep-layer cyclone feed device slowly rotates around a central column under being driven by power, when materials gets into from the upper portion of the distributing barrel, buffer flow which firstly passes through the screen plate flows on the chocked flow plate, feed liquid slowly drops on the deflector after damping by the chocked flow plate, and the feed liquid is evenly casted in a concentration tank by the choked flow refracting plates, thereby lowering the inflowing intensity of feed liquid, prolonging the detention time of feed liquid, reaching the purpose of feeding in deep layer and settling in advection, and leading the settling effect of material and the working efficiency of the thickener to be greatly improved. The deep-layer cyclone feed device is particularly suitable for the central transmission whose center is provided with an upright post or the feed of a peripheral transmission thickener.
Description
Technical field
The utility model relates to a kind of feeding device of thickener, the deep layer eddy flow feeding device of holdup time that especially can prolong material particles to greatest extent in concentration basin.
Background technology
At present, generally do not establish any device in the cloth charging basket of known thickener, what have also only installs one additional and filters sieve plate.Its enter material way is almost without any directly feeding in the pond with mixing of materials water with blocking, because the pan feeding flow velocity is bigger, not only material is not free fully to be precipitated, even if what precipitated is material bed, because being subjected to constantly washing away also of follow-up feed liquid is destroyed, both influenced the effect of settling of material particles, and the water concentration that overflows is bigger, has also caused the waste of material.
Summary of the invention
The purpose of this utility model is to overcome existing in prior technology feed liquid holdup time weak point in concentration basin, the shortcoming and defect of solid content effect of settling difference provides a kind of deep layer eddy flow feeding device, and this device can slow down flowing of feed liquid, stablize the material settled layer, improve the feed liquid thickening efficiency.
For achieving the above object, the technical solution adopted in the utility model is: the cloth charging basket is fixed on the deflector by bracing frame, and deflector is circular; In the cloth charging basket sieve plate below be provided with spoiler, spoiler is on the inwall that downward-sloping circular of inner ring be fixed on the cloth charging basket; Circumference vertical fixing along deflector has a plurality of radial equally distributed choked flow deflecting plates that are, and the plane of each choked flow deflecting plate all bends to cambered surface in the same way.Feed liquid enters from the cloth bung, through falling on the deflector after sieve plate filtration, the spoiler buffering, again after the shunting of choked flow deflecting plate, the comparatively slow concentration basin that flows into weakly, reduced material and flowed into intensity, prolonged the feed liquid holdup time, thereby reached the purpose of deep layer pan feeding, advection sedimentation.
The beneficial effects of the utility model are: can make mobile the slowing down of feed liquid that falls from eminence, avoid the impact failure of fluid to the beds of precipitation, prolong the solid holdup time of shape particle in concentration basin to large extent, improve underflow density, reduce the solid content of overflow water.

The specific embodiment
In Fig. 1, cloth charging basket (1) connects bracing frame (3) and is fixed on the deflector (5); Sieve plate (7) is fixed on the top in the cloth charging basket (1); Spoiler (2) directly is fixed on the middle part of cloth charging basket, and is funnel-form at the downward-sloping certain angle of vertical direction; A plurality of choked flow deflecting plates (4) are radial even distribution, be vertically fixed on the deflector (5), and its shape bend to certain radian in the horizontal direction.Whole feeding device is under power drive, around slowly rotation of newel (6), when material when the top of cloth charging basket (1) enters, at first the buffering through sieve plate (7) flows on the spoiler (2), under the damping of spoiler, feed liquid is gentle to be dropped on the deflector (5) slowly, under the centrifugal action of cloth charging basket rotation, feed liquid is evenly got rid of in the concentration basin by choked flow deflecting plate (4), thereby makes the effect of settling of material and the operating efficiency of thickener obtain bigger raising.There are the center transmission of column or the pan feeding of peripheral traction thickener in the utility model particularly suitable center.
Claims (4)
1, a kind of deep layer eddy flow feeding device comprises cloth charging basket (1) and sieve plate (7); It is characterized in that: cloth charging basket (1) is fixed on the deflector (5) by bracing frame (3); The below of sieve plate in the cloth charging basket (7) is provided with spoiler (2), and spoiler (2) is fixed on the inwall of cloth charging basket (1); Deflector (5) is gone up vertical fixing a plurality of choked flow deflecting plates (4).
2, deep layer eddy flow feeding device according to claim 1 is characterized in that: spoiler (2) is downward-sloping circular of inner ring, shape such as funnel.
