Description

In the cartridge type turbomachine accelerating purifying pool of mesh device is arranged

Technical field: the utility model relates to a kind of cartridge type turbomachine accelerating purifying pool.

Background technology: mechanical accelerating purifying pool circulates settling tank mud, and makes it participate in flocculation reaction, and this guiding theory is all more brilliant than any flocculation reaction technology of present use.But the wheel rotor of all mechanical accelerating purifying pools design at present is very unreasonable.Short to the distance that the former water of dosing is walked in the pond, pool bottom sludge can not destroyed under the alumen ustum basic granules state by impeller again and stirs.Therefore body refuse suspended layer concentration is not enough, and wherein contains the alumen ustum small-particle of a lot of fragmentations.So make and collide flocculation reaction poor effect as the general mechanical accelerating purifying pool of flocculation reaction mechanism with alumen ustum tiny in the former water of dosing and suspension slime layer mud, a lot of such pond body loads can only reach 50～70% of design load, we have declared cartridge type turbomachine accelerating purifying pool for the shortcoming that overcomes this class pond type, patent No. ZL 02 21085.2, and the flocculation reaction effect of this pond type is compared with universal machine accelerating purifying pool pond type and is improved largely.This pond type also has shortcoming, i.e. the former water of dosing enters after the cylinder of cartridge type cylindrical surface impeller, and the mechanism of the mud contact-impact of it and suspension mobile slime layer is still not ideal enough, and the collision probability is not high enough.We have the cartridge type turbomachine accelerating purifying pool of mesh device in having proposed in order to improve this collision probability.

The utility model content: the purpose of this utility model provides a kind of mud contact-impact mechanism that can effectively change former water of dosing and suspension mobile slime layer, and the cartridge type turbomachine accelerating purifying pool of mesh device is arranged in the raising probability of collision.Technical scheme: the cartridge type turbomachine accelerating purifying pool that mesh device is arranged in a kind of, have cylindrical surface sleeve, blade, impeller upper cover plate, water leg, motor, cover body, the cover plate of pond body, shore pipe, impeller, it is characterized in that: be provided with mesh device in the sleeve of cylindrical surface.Beneficial effect: contrast with the universal machine accelerating purifying pool, the former water of the utility model dosing enters in the sleeve of cylindrical surface at the position, the high dense district of bottom mud near the pond body, because mud can not radially flow out, can only upwards flow, so sludge concentration height, the throwing out that adds upper bush Intranet lattice device has improved flocculating effect greatly, and the load of settling tank improves nearly 1 times; Compare with cartridge type turbomachine accelerating purifying pool, because of the effect of mesh device in the sleeve, it significantly improves the flocculation reaction effect of mud in the tiny alumina blossom particles of the former water of dosing in the sleeve of cylindrical surface and the suspension slime layer.Because the flocculation reaction of former water fine particle of dosing and suspension slime layer is most important in the sleeve of cylindrical surface, so it can make the settling tank load improve nearly 50%.

Embodiment: as shown in Figure 1, the utility model is made up of mesh device 4, blade 5, impeller upper cover plate 6, water leg 7, motor 8, cover body 9, cover plate 10 in pond body 1, shore pipe 2, impeller cylindrical surface sleeve 3, the sleeve, and wherein mesh device 4, blade 5 have mesh device cartridge type impeller in forming in impeller upper cover plate 6, impeller cylindrical surface sleeve 3, the sleeve.The lower inside of blade 5 is made and be fixed on to sleeve 3 usefulness stainless-steel sheets in impeller cylindrical surface.Cover body 9 is positioned at pond body 1 and connects with 1 support of pond body, the upper end of blade 5 connects with impeller upper cover plate 6, its underpart connects with impeller cylindrical surface sleeve 3, impeller cylindrical surface sleeve 3 is positioned at cover body 9, impeller upper cover plate 9 connects with motor 8 by axle, cover plate 10 connects with the upper end of pond body 1, and motor 8 is bearing in above the cover plate 10.Water leg is positioned at settling region III, is bearing on the pond body 1, and shore pipe 2 is positioned at the bottom of pond body 1.

During enforcement, as Fig. 2, shown in Figure 5, mesh device can be made of vertical placement of a plurality of rectangular nodes in the sleeve, and each rectangular node medullary ray is concentric with the cylindrical surface sleeve centerline, and with the cylindrical surface socket joint.The concrete structure of grid is, is that rectangular plastic is made glazing bar 14 equidistant quadratures and connected and make mesh flake by cross section, is connected with housing 15 that stainless steel is made and makes grid.

As Fig. 1, Fig. 3, Fig. 4, shown in Figure 6, mesh device can also becoming with the concentric circular net lattice of cylindrical surface sleeve centerline by a plurality of horizontal positioned in the sleeve, a plurality of vertical round steel or angle steel connect into the grid case with circular grid, leave the gap between grid case and the cylindrical surface sleeve, support and be fixed on body bottom, pond.Concrete structure is, cross section is made glazing bar 11 equidistant quadratures connections for circular plastics and is made mesh flake, be connected with housing 12 that stainless steel is made again and make grid, the circular grid periphery of a plurality of horizontal positioned fuses with a plurality of vertical round steel or angle steel 13, and these round steel or angle steel is fixed on the bottom of pond body 1.

Between cover body 9 and the cylindrical surface sleeve 3 is the I reaction chamber, and the upper cover plate of impeller is the II reaction chamber more than 6, and upper periphery is cloth pool IV in the cover body 9, is settling region III between cover body 9 outsides and the pond body 1.The former water of dosing enters the I reaction tank by cloth pool IV.Because the rotation of impeller vane 5, impeller cylindrical surface sleeve 3, the bed mud at 1 end of pond body is stirred, form the body refuse suspended layer, and be inhaled within the cylindrical surface sleeve 3.Mud contact-impact in former water of dosing and the body refuse suspended layer carries out flocculation reaction.When wheel rotation, drive water body rotation in the sleeve 3 of cylindrical surface, but the former rotating speed is greater than the latter's rotating speed.Mesh device 4 is the rectangular node of a plurality of vertical placements medullary rays by cylindrical surface sleeve 3 in sleeve, and during the form of joining with the inwall of cylindrical surface sleeve 3, the rotary speed of mesh device 4 is greater than the flow velocity in the cylindrical surface sleeve 3, back at each glazing bar 14 of grid, produce a series of little vortex, these little vortexs merge the more small vortex of generation in flowing, under their centrifugal inertia effect, improved mud probability of collision in the particle of alumen ustum flco trickle in the former water of dosing and the suspension slime layer significantly.Mesh device 4 is the circular grids of a plurality of horizontal positioned in sleeve, its periphery fuses with a plurality of vertical round steel or angle steel, and when being fixed on the form of pond body 1 bottom, when the former water of dosing upwards flows through these grids, all produce a series of little vortex in each grid glazing bar 11 back, these little vortexs merge the more small vortex of generation in current, because their centrifugal inertia has increased the probability that mud collides in alumen ustum tiny in the former water of dosing and the suspension slime layer significantly.Such two kinds of situations since the effect of grid the tiny alumina blossom particles of former water is fully flocculated when flowing through the suspension slime layer magnifies, improve its settling velocity greatly.When the former water of dosing upwards flow to the place that does not have cylindrical surface sleeve 3, radially flow out along impeller periphery, a part enters into the II reaction chamber, and a part turns back to the bottom of pond body 1, is absorbed by the cartridge type impeller simultaneously to promote; The current that enter the II reaction tank continue to enter settling region III after the flocculation reaction and precipitate, its top clear water enters water leg 7, sedimentary mud slides into the centre of pond body 1 bottom along slope, bottom surface, pond, promoted by cylindrical surface sleeve 3, and unnecessary mud is regularly discharged by shore pipe 2.
