Abstract

The present invention discloses a vortex sand-water separator and provides the vortex sand-water separator which is simple in structure and avoids clogging of sand discharge pipes. The vortex sand-water separator includes a grit chamber. The grit chamber includes a chamber body, a driving device, a blade wheel and a sand discharge pipe. A water inlet is arranged on the upper side wall of the chamber body via a tangential direction, a water outlet is arranged at the middle of the upper sidewall, a grit hopper is arranged at the bottom of the chamber body, and an upper part of the sand discharge pipe stretches out from the chamber body and an lower part of the sand discharge pipe is located within the grit hopper. The vortex sand-water separator also includes a sand cover and a tapered hopper. The tapered hopper presents a hopper shape which is small at the top and large at the bottom and arranged at the bottom of the sand discharge tube, and a deflector rod is arranged within the conical hopper. The sand cover is arranged on the sand discharge pipe and the conical hopper is coated in the sand cover. The sand cover and the conical hopper are arranged at the lower part of the sand discharge pipe. The sand cover can filter sand grains at work to avoid large volumes of sand grains clogging the sand discharge pipe. Then the tapered hopper gathers the sand into the sand discharge pipe to discharge the sand and improves the reliability of the sand discharge.

Description

A kind of eddy flow grit water separator

Technical field

The present invention relates to sewage treatment area, particularly relate to eddy flow grit water separator.

Background technology

Eddy flow grit water separator is the equipment going out sand grains in sewage work for separation and Extraction from sewage, comprises rotational flow grit chamber. Usually being provided with one in rotational flow grit chamber of the prior art for promoting the row's sand pipe of the heavy sand bottom rotational flow grit chamber, this row's sand pipe upper end is connected with the water leg of grit water separator by pipeline, and lower end extends to bottom rotational flow grit chamber. But, at work, often there is latch up phenomenon in row's sand pipe, needs the artificial block clearing of frequent employing, had both added cost of labor, and can affect again the normal use of grit water separator, reduce the separation efficiency of sand water.

Summary of the invention

The present invention is directed to above problem, it provides a kind of structure letter is answered, the eddy flow grit water separator of the row's of avoiding sand blockage.

The technical scheme of the present invention is: comprise rotational flow grit chamber, described rotational flow grit chamber comprises pond body, drive unit, impeller and row's sand pipe, the upper portion side wall of described pond body is tangentially provided with water-in, the centre of upper portion side wall be provided with water outlet, the bottom of described pond body is sand deposition hopper, and described pond body is stretched out on the top of described row's sand pipe, bottom is positioned at sand deposition hopper;

Also comprising sand cover and taper bucket, described taper bucket is up-small and down-big bucket-shaped, and described taper bucket is located at the bottom of described row's sand pipe, is provided with driving lever in described taper bucket;

Described sand is located on described row's sand pipe, and described taper bucket is coated in described sand cover.

Also comprising blast main and rinse tracheae, described blast main is connected the bottom of described row's sand pipe, and described flushing tracheae is positioned at the lower section of described row's sand pipe.

Screening principle when the present invention rotates in the body of pond according to the solid particulate in fluid is made, when current under pressure from water-in tangentially to enter Chi Tihou, produce strong rotary motion, owing to sand is different with water-mass density, under the acting in conjunction of centrifugal force, centripetal force, buoyancy and fluid drag force, the liter waterborne making density low, is discharged by water outlet, the sand grains that density is big is gathered in sand deposition hopper, is discharged by row's sand pipe. The lower section of row's sand pipe arranges sand cover and taper bucket, and sand cover is at work, it is possible to filter sand grains, avoids sand grains blocking row's sand pipe of comparatively large vol; Then, be focused in row's sand pipe by taper bucket and arrange sand, meanwhile, the driving lever arranged in taper bucket, is convenient to dispersion sand grains, it is to increase the reliability of row's sand.

Accompanying drawing explanation

Fig. 1 is the structural representation of the present invention,

Fig. 2 is the vertical view of Fig. 1,

Fig. 3 arranges the structural representation bottom sand pipe in the present invention;

In figure, 1 is row's sand pipe, and 2 is drive unit, and 3 is impeller, and 4 is blast main, and 5 is rinse tracheae, and 6 is taper bucket, and 7 is driving lever, and 8 is sand cover, and 9 is pond body, and 10 is water-in, and 11 is water outlet.

Embodiment

The present invention is as Figure 1-3, comprise rotational flow grit chamber, described rotational flow grit chamber comprises pond body 9, drive unit 2, impeller 3 and row's sand pipe 1, the upper portion side wall of described pond body 9 is tangentially provided with water-in 10, the centre of upper portion side wall be provided with water outlet 11, the bottom of described pond body 9 is sand deposition hopper, and described pond body 9 is stretched out on the top of described row's sand pipe 1, bottom is positioned at sand deposition hopper; In work, drive unit 2(and motor) drives impeller 3 action so that there is stirring action in the body of pond;

As shown in Figure 3, also comprising sand cover 8 and taper bucket 6, described taper bucket 6 is in up-small and down-big bucket-shaped, and described taper bucket 6 is located at the bottom of described row's sand pipe 1, is provided with driving lever 7 in described taper bucket 6;

Described sand cover 8 is located on described row's sand pipe 1, and described taper bucket 6 is coated in described sand cover 8. Sand cover is convenient to filter sand grains, and taper bucket is convenient to assemble sand grains and is convenient to discharge.

Also comprising blast main 4 and rinse tracheae 5, described blast main 4 is connected the bottom of described row's sand pipe 1, and described flushing tracheae 5 is positioned at the lower section of described row's sand pipe 1; Arranging blast main and rinsing tracheae makes by aeration, avoids the phenomenon that sand grains is piled up, blocked.
