Abstract

The utility model relates to a cylindrical mechanical accelerated clarifier with a grid device inside, which can effectively improve the collision mechanism between the raw water with medicine and the sludge in the flowing suspension sludge blanket so as to increase the collision probability. The utility model has the technical scheme that the utility model is provided with a clarifier body, a sludge discharge pipeline, a cylindrical surface sleeve, blades, an upper cover plate for impellers, a water collecting tank, a motor, a hood and a cover plate. The utility model is characterized in that a grid device is arranged in the cylindrical surface sleeve which is fixed with the bottom of the clarifier body. Compared with the cylindrical impeller mechanical accelerated clarifier, because of the gird device in the sleeve, the utility model greatly enhances the flocculation reaction effect between the thin alum particles in the raw water with medicine and the sludge in the flowing suspension sludge blanket in the cylindrical surface sleeve. Because the flocculation reaction between the thin alum particles in the raw water with medicine and the flowing suspension sludge blanket in the cylindrical surface sleeve is the most important, the utility model can enhance the load of a settling pond by about 50%.

Description

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

Technical field: the utility model relates to a kind of novel mechanical accelerating purifying pool.

Background technology: mechanical accelerating purifying pool circulates sedimentation basin 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.The distance that causes the former water of dosing to be walked in the pond is short, and pool bottom sludge can not destroyed under the alumen ustum basic granules state by impeller again and stirs.Therefore body refuse superposed layer concentration is not enough, and wherein contains the alumen ustum granule 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 face of cylinder impeller, and it is still not ideal enough with the mud contact-impact mechanism of the mobile slime layer that suspends, and the collision probability is not high enough.We have the cartridge type mechanical 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 the former water of dosing and the slime layer that suspend to flow, improve the collision probability in the cartridge type mechanical accelerating purifying pool of mesh device is arranged.Technical scheme: the cartridge type mechanical accelerating purifying pool that mesh device is arranged in a kind of, have pond body, discharge pipeline, face of cylinder sleeve, blade, impeller upper cover plate, water leg, motor, cover body, cover plate, it is characterized in that: face of cylinder sleeve and pond body bottom are fixing, and its inside is provided with mesh device.Beneficial effect: contrast with the universal machine accelerating purifying pool, the former water of the utility model dosing enters in the sleeve of the face of cylinder 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 flocculation that adds upper bush Intranet lattice device has improved flocculating effect greatly, and the load of sedimentation basin 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 the face of cylinder 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 the face of cylinder, so it can make the sedimentation basin load improve nearly 50%.And because the face of cylinder of the present utility model sleeve and pond body bottom are fixing, processing installs more convenient.

Description of drawings:

Fig. 1 is the overall cutaway view of the utility model;

Fig. 2 has the cutaway view of mesh device sleeve in being;

Fig. 3 is the cutaway view of mesh device.

The specific embodiment: as shown in Figure 1, the utility model is made up of pond body 1, discharge pipeline 2, face of cylinder sleeve 3, channel-section steel 4, blade 5, impeller upper cover plate 6, water leg 7, motor 8, cover body 9, cover plate 10.Sleeve 3 usefulness corrosion resistant plates in the face of cylinder are made and are fixed on the bottom of pond body 1 with channel-section steel 4, and its inside is provided with mesh device.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, and face of cylinder sleeve 3 is positioned at cover body 9, and impeller upper cover plate 6 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 zone III, is bearing on the pond body 1, and discharge pipeline 2 is positioned at the bottom of pond body 1.

As Fig. 1, Fig. 2, shown in Figure 3, mesh device becoming in the sleeve of the face of cylinder by a plurality of horizontal positioned with the concentric circular net lattice of face of cylinder sleeve centerline, the structure of circular grid is, by cross section is that the equidistant quadratures of plastic strip 11 of triangle or rectangle connect and make mesh flake, mesh flake is connected with stainless steel housing 12 makes grid, the circular grid periphery of a plurality of horizontal positioned is linked to be the grid case 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.Leave the gap between grid case and the face of cylinder sleeve.

Between cover body 9 and the face of cylinder sleeve 3 is the I reative cell, and the upper cover plate of impeller is the II reative cell more than 6, and upper periphery is cloth pool IV in the cover body 9, is settling zone 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 blade 5 stirs pond body 1 bed mud, form the body refuse superposed layer, and be inhaled within the face of cylinder sleeve 3.When the former water of dosing upwards flows through the circular grid of these horizontal positioned, 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.Magnify, improve its sinking speed greatly because the effect of grid is fully flocculated the tiny alumina blossom particles of former water when flowing through the suspension slime layer.When the former water of dosing upwards flow to the place that does not have face of cylinder sleeve 3, radially flow out along impeller periphery, a part enters into the II reative cell, 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 zone III after the flocculation reaction and precipitate, its top clear water enters water leg 7, the mud of precipitation slides into the centre of pond body 1 bottom along slope, bottom surface, pond, promoted by face of cylinder sleeve 3, and unnecessary mud is regularly discharged by discharge pipeline 2.
