Abstract
The utility model discloses a sand swirl collector which is characterized by comprising a cylindrical shell with an inner cavity, wherein a backflow water outlet is arranged at the upper part of the shell, a water outlet is arranged at the lower part of the shell, and the caliber of the backflow water outlet is larger than the caliber of the water outlet; a water inlet connected with a water inlet pipe is also arranged at the mid-upper part of the shell, and an included angle is formed between the water inlet pipe and a plane formed between axes of the water inlet and the shell. Proved by engineering practice, the sand swirl collector is mounted at the upper part of a sand and water separator, sand pumped by a sand-conveying pump through a pipeline is washed to separate water and organic matter, most sand and organic matter can fall in a hopper of the sand and water separator, and the rest, about 95 percent of organic matter and 93 percent of pump-pressed sewage, flows back to a water inlet channel.
Description
Technical field
The utility model relates to a kind of municipal effluent, the pretreated sand grains collector of industrial sewage, particularly a kind of sand grains eddy flow collector of being used for.
Background technology
Deceleration stirrer commonly used stirs sewage when municipal effluent, industrial sewage pre-treatment, makes sewage and sand grains preliminary sedimentation in settling pit, rises to grit water separator with Sand pump then and separates sand grains in the sewage.Now present domestic pumping plant sand grains pre-processing device volume is big, and the sand grains separation rate is low.Separate in advance as foreign material (rubbish, bag, paper, sanitary towel, sand) in the not first pretreating sewage in municipal effluent, industrial sewage water technology, will influence the normal operation of subsequent technique, serious consequence is the ordinary life that influences equipment.And in the existing apparatus, also do not have simple in structurely, be used for the isolating treatment unit in advance of sand grains.
The utility model content
Goal of the invention: the purpose of this utility model is at the deficiencies in the prior art, and a kind of sand grains eddy flow collector that improves sand water sepn rate is provided.
Technical scheme: the utility model discloses a kind of sand grains eddy flow collector, it is characterized in that, comprise the cylindrical housings of being with inner chamber, housing top is provided with the recirculation water outlet, and lower housing portion is provided with water outlet, and described recirculation water outlet bore is greater than water outlet aperture; The housing middle and upper part also is provided with the water-in that is connected with water inlet pipe, is an angle between the plane that water inlet pipe and described water-in and housing shaft line form.Described angle is the right angle.
In the utility model, preferably, described angle is the right angle.Can increase the swirl velocity of water inlet thus to greatest extent, thereby improve sand water sepn efficient.
In the utility model, preferably, also be provided with the cylindrical inner housing of a hollow in the outlet of the recirculation water of housing closely, the inner housing bottom extends to below the water-in plane.
In the utility model, further improve, housing top outer rim and inner housing middle part outer rim connect by flange, can influence sand grains eddy flow collector works better in case pollutent stops up the back so that unload and clean housing thus.
Beneficial effect: the utility model proves through engineering practice, the sand grains collector is installed in the top that sand moisture is disembarked, by pipeline with the sand grains in the sediment transport pump suction wash grain, water separates with organic, most of sand grains and organism will drop down onto in the hopper that sand moisture disembarks, and remaining about 95% organism and about 93% pump pressure sewage backflow are to irrigation channel.Particularly, possess following three place's advantages: 1, adopt sand grains collector sand water sepn rate height.2, material-saving---grit water separator can significantly reduce volume, the shock-resistant peak load water yield.3, use the whole sand water separation equipment floor space in back few.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation.
Fig. 1 is the utility model sand grains eddy flow collector sectional view.
Fig. 2 is the utility model vertical view.
Embodiment
As shown in Figure 1, the utility model discloses a kind of sand grains eddy flow collector, comprise the cylindrical housings 1 of being with inner chamber, housing 1 top is provided with recirculation water outlet 2, and lower housing portion is provided with water outlet 3, and described recirculation water exports 2 bores greater than water outlet 3 bores; Housing 1 middle and upper part also is provided with the water-in 5 that is connected with water inlet pipe 4, is an angle between the plane that the axis of water inlet pipe 4 and described water-in 5 and housing 1 forms.As shown in Figure 2, described angle is the right angle.Also be provided with the cylindrical inner housing 6 of a hollow in the recirculation water outlet 2 of housing 1 closely, inner housing 6 bottoms extend to below water-in 5 planes.Housing 1 top outer rim and inner housing 6 middle part outer rims connect by flange 7.
The utility model principle of work is as follows: sand grains eddy flow collector is installed in the top that sand moisture is disembarked; after by pipeline the sand grains mixed solution in the sediment transport pump suction being entered sand grains eddy flow collector and washes grain is sand; water separates with organic; by the tangential direction sand grains eddy flow collector of intaking; the sand water mixed liquid is portion's centrifugal motion within it; most of sand grains density difference different according to the sand grains mixed solution; sand grains drops down onto in the hopper that sand moisture disembarks; because the upper water-out return line in this device is bigger than the lower discharging tube footpath; most sand grains flows to grit water separator by sand grains eddy flow collector lower discharging tube footpath gravity in the sand grains mixed solution, and remaining about 95% organism and about 93% pump pressure sewage backflow are to irrigation channel.The sand grains collector all adopts the 3Cr13 corrosion-resistant, that wear resisting property is high to make.
Municipal effluent and industrial sewage preprocessing process can alleviate back road work of treatment amount after installing by this, reduce the sewage disposal device volume, improve sewage treating efficiency.
The utility model provides a kind of thinking and method of sand grains eddy flow collector; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
