Abstract
A novel thickener distribution barrel resolves problems that suspension is hard to deposit, overflow concentration is high and underflow thickening effect is poor. The thickener distribution barrel is characterized in that a choking deflector (2) is connected below a common thickener distribution barrel (1), the choking deflector (2) which is conical matches with the bottom of the thickener distribution barrel (1) and forms an angle ranging from 10 degrees to 50 degrees downwards horizontally to be provided with a plurality of curved partition boards (3), and insert depth of the choking deflector (2) is distant from the liquid level of an overflow tank (4) by 1.0-2.5m. The novel thickener distribution barrel is adaptable to suspension thickening purification application in the fields of the mining industry, environmental protection, coal and the like and has the advantages of obviously improving thickener overflow and underflow concentrations, reducing flocculant usage and increasing processing effect of thickeners.
Description
Affiliated technical field:
The utility model belongs to the thickening-purification technology equipment manufacturing technology field of inner suspension liquid, is specifically related to a kind of novel thickener cloth charging basket, and the thickening-purification technology that is adapted to field inner suspension liquid such as mining industry, environmental protection, coal is used
Background technology: existing thickener exists the cloth charging basket shorter, more shallow in the insertion water, after suspension entered thickener, solid particle and thickener distance from bottom were far away, will some particle in the process of sedimentation downwards by the current band people settling section that upwards flows, destroy the clear water layer; When the thickener beds of precipitation were thicker, because the no buffer unit in cloth charging basket bottom, the beds of precipitation can directly impact because of the suspension of high speed pan feeding and be destroyed, and also can dig the suspension water of high concentration sometimes in addition.Finally cause suspension to be difficult for precipitation, the effluent concentration height, the underflow concentrated effect is poor simultaneously, and underflow density is on the low side.
Summary of the invention:
The utility model purpose is exactly for overcoming above deficiency, and a kind of the making in conjunction with relevant flow dynamic that provides learned principle and actual conditions, by the improvement to distributing mode, reaches the novel thickener cloth charging basket that reduces the thickener effluent concentration and improve underflow density.
The utility model is to realize like this, described novel thickener cloth charging basket is to connect a choked flow deflecting plate (2) down at common thickener cloth charging basket (1), the taper shape that is set to that it is characterized in that choked flow deflecting plate (2), and be complementary with the bottom of thickener cloth charging basket (1), choked flow deflecting plate (2) level becomes 10-50 ° angle downwards, the form with rotating flow slowly flows into concentration basin simultaneously, and cloth charging basket and choked flow deflecting plate insertion depth are to select between the 1.0-2.5m of overflow liquid pool (4) liquid level.The two blocks of conical steel plates that the choked flow deflecting plate is emptied by the centre or the dividing plate (3) of several band radians are formed, look like the impeller that keeps flat, the epicone plate hole is feed end greatly, and following cone-plate hole is little tightly to be cooperated with the mixed earth pillar of thickener center reinforcing bar, so that suspension is not missed from the bottom.Speed slows down under the refraction of choked flow deflecting plate cone-plate after suspension enters the cloth charging basket with certain speed, and the curved channel that forms from dividing plate becomes direction of rotation slowly to flow out then.
Novel thickener cloth charging basket of the present utility model is compared with common cloth charging basket, three advantages are arranged, the one, cloth charging basket bottom is near at the bottom of concentration basin, when suspension is flowed out by cloth charging basket bottom, shortened the distance of solid particles sediment at the bottom of the pond, increase the particle come-up and entered the resistance of overflow, thereby helped solid particles sediment at the bottom of making most of particle enter the pond, improved effect of settling; The 2nd, suspension becomes rotating flow to flow out from cloth charging basket choked flow deflecting plate, has increased the stroke that solid particle flows in the thickener centre, thereby has prolonged the sedimentation time, improves effect of settling; The 3rd, the angle that choked flow deflecting plate level is downward-sloping 10-50 ° had both guaranteed that the deposit seed layer was not destroyed, had prolonged the distance of solid particle to the thickener overfall again.
Novel thickener cloth charging basket of the present utility model has thickener overflow, underflow density and has all obtained tangible improvement, and effluent concentration generally is no more than 5g/l, and underflow density is improved, and more common thickener improves 20-30%.But also can reduce the use amount of flocculant, and on average reduce about 40%, improved the advantage of thickener disposal ability.

Accompanying drawing 1 is novel thickener cloth barrel knot composition
Accompanying drawing 2 is novel thickener cloth charging basket choked flow deflecting plate plane structure chart
Accompanying drawing 3 is novel thickener cloth charging basket choked flow deflecting plate sectional structure chart
Among the figure: 1. thickener cloth charging basket, 2. choked flow deflecting plate, the 3. dividing plate of band radian, 4. overflow liquid pool
The specific embodiment:
Below in conjunction with accompanying drawing embodiment, the utility model is further described, novel thickener cloth charging basket as shown in Figure 1 is to connect a conical choked flow deflecting plate (2) down at common thickener cloth charging basket (1); Accompanying drawing 2 is the dividing plate (3) of a plurality of band radians in novel thickener cloth charging basket choked flow deflecting plate plane, accompanying drawing 3 is the taper shape that is set to of novel thickener cloth charging basket choked flow deflecting plate (2), and with the coupling of the bottom of thickener cloth charging basket (1), choked flow deflecting plate level becomes 10-50 ° angle downwards, the form with rotating flow slowly flows into concentration basin simultaneously, and cloth charging basket and choked flow deflecting plate insertion depth are to select between the 1.0-2.5m of overflow liquid pool (4) liquid level.The two blocks of conical steel plates that the choked flow deflecting plate is emptied by the centre or the dividing plate (3) of several band radians are formed.
