Abstract

The utility model relates to a sand trap which comprises a tank body, wherein both ends of the tank body are respectively provided with a water inlet pipe and a water outlet pipe; at least 5 partitions are uniformly distributed in the tank body in the longitudinal direction; the included angle alpha between a middle bottom plate in the tank body and the vertical direction is 60-85 degrees; the lowest end of the middle bottom plate is provided with a sand accumulation region; and the highest end of the middle bottom plate is provided with a water outlet region. The inclined bottom plate and the partitions arranged in the tank body reduce the flow rate of wastewater; after the sand-containing wastewater is obstructed by the partitions, sand grains sink under the action of gravity, thereby forming the layer-by-layer buffer and continuous sand settling process; and the settled sand grains and impurities automatically slide to the sand accumulation region to accumulate through the inclined floor. The utility model has the advantages of simple structure, low cost and favorable sand removal effect.

Description

A kind of sand-settling device

Technical field

The utility model relates to a kind of water treatment facilities, relates in particular to a kind of sand-settling device.

Background technology

When handling the more waste water of water system mixture, need be removed the size particles impurity in the waste water in advance, to alleviate subsequent treatment pressure, place the particle hardness of matter to the damage of equipment.Conventional processes is with gravitational settling and be filtered into the master, gravitational settling often adopts the mode of Da Chi standing sedimentation, treatment effeciency is lower, and directly the filter type cost is higher, need in time cleaning filter screen or replacing filter bag, cost is higher, and filters problems such as obstruction takes place when height contained assorted wastewater treatment easily.

The utility model content

At the problems referred to above, the purpose of this utility model provides a kind of simple structure, with low cost, sand-settling device that desanding effect is good.

The utility model technical scheme of taking of dealing with problems is:

A kind of sand-settling device, comprise the pond body, these body two ends, pond are respectively arranged with water inlet pipe and outlet pipe, in the body of pond, vertically be evenly equipped with at least 5 dividing plates, the central floor panel of pond body and vertical direction angle α are 60 ° ~ 85 °, the least significant end of central floor panel is provided with poly-sand district, and the most significant end of central floor panel is provided with exhalant region.

The beneficial effects of the utility model are: by pond body inclined floor and dividing plate setting, the waste water flow velocity slows down, contain sand waste water dividing plate and stop that the back sand grains sinks under the gravity effect, thereby form buffering layer by layer, the sand setting process of continuous sedimentation successively, the sand grains after the sedimentation and impurity slide to poly-sand district automatically by ramped floor assembles, and has simple in structure, advantage with low cost, that desanding effect is good.

Description of drawings

Fig. 1 is front view of the present utility model;

Fig. 2 is vertical view of the present utility model.

Among the figure: water inlet pipe 1, pond body 2, outlet pipe 3, dividing plate 4, poly-sand district 21, exhalant region 22, central floor panel 23.

The specific embodiment

Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.

Embodiment:

As shown in Figure 1 and Figure 2, a kind of sand-settling device, comprise pond body 2, these pond body 2 two ends are respectively arranged with water inlet pipe 1 and outlet pipe 3, in pond body 2, vertically be evenly equipped with at least 5 dividing plates 4, central floor panel 23 and the vertical direction angle α of pond body 2 are 60 ° ~ 85 °, and the least significant end of central floor panel 23 is provided with poly-sand district 21, and the most significant end of central floor panel 23 is provided with exhalant region 22.

Operation principle of the present utility model is: sewage enters pond body 2 by water inlet pipe 1, pond body 2 and dividing plate 4 stop and the effect that cushions under current become very slow, fine particle impurity in the sewage and sand grains sink under the effect of gravity gradually, through dividing plate 4 time, sewage passes from beneath, the granule foreign of water is blocked by baffle plate 4 and slowly sinks at the bottom of the pond on the central floor panel 23, and only surplus a spot of sand grains passes at interval at the bottom of the pond that is lower than dividing plate 4.So repeatedly, after sewage passes through from least 5 dividing plates 4 belows, form buffering, successively the sand setting process of continuous sedimentation layer by layer.Sand grains impurity layer at the bottom of the pond has played the effect of a simple filtration to sewage, makes sand grains be removed substantially.Because central floor panel 23 has certain inclination angle, sink to sand grains at the bottom of the pond along the inclination direction slip to poly-sand district 21, regularly by the labor cleaning.Enter exhalant region 22 by the sewage behind the dividing plate 4, discharged by outlet pipe 3.

Claims

1. sand-settling device, comprise pond body (2), these pond body (2) two ends are respectively arranged with water inlet pipe (1) and outlet pipe (3), it is characterized in that: in pond body (2), vertically be evenly equipped with at least 5 dividing plates (4), the central floor panel (23) of pond body (2) is 60 ° ~ 85 ° with vertical direction angle α, the least significant end of central floor panel (23) is provided with poly-sand district (21), and the most significant end of central floor panel (23) is provided with exhalant region (22).
