Abstract

The invention discloses a cyclone desander including a cylindrical drum (1), a conical drum (2) and a bracket (8), wherein the side wall of the cylindrical drum (1) is provided with a water inlet (3), the top of the cylindrical drum (1) is provided with an overflow water outlet (4), the bottom of the conical drum (2) is provided with a sewage discharge port (5), a sewage storage tank (6) is fixedly arranged on the conical drum (2), the sewage storage tank (6) and the sewage discharge port (5) are communicated, and the sewage storage tank (6) is in fixed connection with a stop valve (7). The beneficial effects of the cyclone desander are that: the stop valve is turned on only when large particle impurities gather in the sewage storage tank (6) and need to be intensively discharged, the number of times of sand discharge can be reduced, labor intensity can be reduced, water loss can be avoided, economic losses can be reduced; in addition, the spiral structural inner wall design enables the suspension in the water to gather more easily, and at the same time also enables water to spirally flow downward, so that wear is minimized, and slag removal efficiency is improved.

Description

A kind of desander

Technical field

The present invention relates to a kind of equipment for separating liquid from solid, particularly a kind of hydrocyclone.

Background technology

China river at present, river, lake, in sea and underground water, the content of silt is very high, domestic water to industrial water and resident produces serious influence, hydrocyclone is a kind of solid-liquid separating equipment of making according to centrifugal sedimentation and density contrast mechanics principle, when current with certain pressure and flow velocity from the import of hydrocyclone enters its inside, water body produces strong rotation because being subject to the impact of hydrocyclone structure, because the density of water and sand is different, at buoyancy, centripetal force and fluid are dragged under the acting in conjunction of power, the clear water that density is little rises and is flowed out by top overfall, the sand that density is large is deposited to bottom and is discharged by sewage draining exit along desander inwall.

In desanding process, under the effect of high speed centrifugation power, very large to the inwall working lining impact of desander, inner wall abrasion is more serious, thereby causes shorten service life, changes frequently, and impact is production normally, increases production cost.In addition, in some cases, in water, sand content is very high, because desander volume is limited, if sediment outflow not in time, the gravel settling down along inwall can be taken out of by the water of forward spin flow, reduce the performance of hydrocyclone, therefore most hydrocyclone is directly opened sewage draining exit and is carried out sediment outflow, can cause so a large amount of water bodys to run off, waste resource, increases cost.

Summary of the invention

The object of the invention is to overcome the shortcoming of prior art, provide a kind of simple in structure, economical and practical, wearability is good, the hydrocyclone of long service life.

Object of the present invention is achieved through the following technical solutions: a kind of hydrocyclone, it comprises pillar buoy, conically shaped and support, the sidewall of described pillar buoy is provided with water inlet, the top of described pillar buoy is provided with and overflows the mouth of a river, the bottom of described conically shaped is provided with sewage draining exit, on described conically shaped, be installed with sewage groove, described sewage groove is communicated with sewage draining exit, and described sewage groove bottom is fixedly connected with stop valve.

Described pillar buoy and conically shaped are ceramic cylinder.

Described pillar buoy and conically shaped inwall are helical structure.

The present invention has the following advantages: when the large granular impurity in water is pooled to, in sewage groove, to need to concentrate discharge be just to open stop valve, can reduce sediment outflow number of times, reduce labour intensity, avoid water body to run off, reduce economic loss, in addition, the inwall design of helical structure, can make suspension in water more easily assemble, and also can make water flow in the shape of a spiral simultaneously downwards, make wearing and tearing be down to minimum, improve slagging-off efficiency.

Brief description of the drawings

Fig. 1 is structural representation of the present invention

In figure, 1-pillar buoy, 2-conically shaped, 3-water inlet, 4-overflows the mouth of a river, 5-sewage draining exit, 6-sewage groove, 7-stop valve, 8-support.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:

As shown in Figure 1, a kind of hydrocyclone, it comprises pillar buoy 1, conically shaped 2 and support 8, the sidewall of described pillar buoy 1 is provided with water inlet 3, the top of described pillar buoy 1 is provided with and overflows the mouth of a river 4, and the bottom of described conically shaped 2 is provided with sewage draining exit 5, on described conically shaped 2, is installed with sewage groove 6, described sewage groove 6 is communicated with sewage draining exit 5, and described sewage groove 6 bottoms are fixedly connected with stop valve 7.Described pillar buoy 1 and conically shaped 2 are ceramic cylinder.Described pillar buoy 1 and conically shaped 2 inwalls are helical structure.

When work, stop valve 7 is in closed condition, the water being flowed into by water inlet 3 can produce strong rotation, because the density of water and sand is different, to drag at buoyancy, centripetal force and fluid under the acting in conjunction of power, the clear water that density is little can rise and be flowed out by overflow outlet 4, the gravel that density is large can be deposited in sewage groove 6 via sewage draining exit 5 along conically shaped 2 inwalls, when the height of gravel rises to while needing sediment outflow gradually, open stop valve 7, the gravel in sewage groove 6 is discharged smoothly under the effect of hydraulic pressure.
