Abstract

The utility model discloses a cyclone desander. The cyclone desander comprises a cylindrical drum, and a conical drum which is fixedly connected with the lower end of the cylindrical drum, wherein a water inlet is arranged at the side of the cylindrical drum, an overflowing water outlet is arranged at the top of the cylindrical drum, the lower end of the conical drum is fixedly connected with a sand storage and discharge device which is communicated with an inner cavity and used for storing and discharging sand. Since the sand storage and discharge device are arranged, the sand discharge times can be reduced, the labor intensity can be lowered, the loss of a water body can be avoided and further the economic loss is reduced. The cyclone desander has the characteristics of being simple in structure and economic and practical. As a desander, the cyclone desander is arranged at a water outlet pipe of a water pump of an underground water taking device.

Description

Hydrocyclone

Technical field

The utility model relates to a kind of equipment for separating liquid from solid, relates in particular to a kind of hydrocyclone that uses in underground water fetching device.

Background technology

At present in China river, river, lake, sea and underground water, the content of silt is very high, industrial water and resident's domestic water is produced have a strong impact on.Hydrocyclone is a kind of solid-liquid separating equipment of making according to centrifugal sedimentation and density contrast mechanics principle.After tangentially entering its inside with certain pressure and flow velocity from the import of hydrocyclone when current, water body produces strong rotation because of the impact that is subjected to the hydrocyclone structure, because the density of water and sand is different, drag at buoyancy, centripetal force and fluid under the acting in conjunction of power, the clear water that density is little rises and is flowed out by the top overfall, the sand that density is large is deposited to the bottom and is discharged by sediment ejection opening along the desander inwall, thereby reaches the purpose of desanding.

In some cases, in water, sand content is very high, because the desander volume is limited, if untimely sediment outflow can be taken out of by the water of forward spin flow along the gravel that inwall settles down, reduce the performance of hydrocyclone, therefore the most hydrocyclone is directly opened sediment ejection opening and is carried out sediment outflow, can cause so a large amount of water bodys to run off, the water yield that slatterns every year is surprising, causes very large economic loss.

The utility model content

For solving the above deficiency that exists in prior art, the utility model provides a kind of hydrocyclone, by setting up the storage sand removing device to reduce the sediment outflow number of times, avoids water body to run off, and then reduces economic loss, has simple in structure, economical and practical characteristics.

For achieving the above object, the technical scheme that adopts of the utility model is as follows:

A kind of hydrocyclone, comprise pillar buoy, be fixed on the conically shaped of pillar buoy lower end, the sidewall of described pillar buoy is communicated with water inlet, and the top is provided with and overflows the mouth of a river, and the lower end of described conically shaped is fixedly connected with the storage sand removing device that is used for Storage and draining gravel that is communicated with its inner chamber.

As to restriction of the present utility model, described storage sand removing device comprises the first valve lock, sand storage bin, the second valve lock that is connected to mutually up and down successively one.

As further restriction, connected firmly by bolt respectively between described the first valve lock and sand storage bin, sand storage bin and second valve lock.

The utility model also has a kind of restriction, and the bottom of described conically shaped outer wall has transparent window.

Owing to having adopted technique scheme, the utility model compared with prior art, obtained technological progress is:

When the utility model normally used, the first valve lock of storage sand removing device was in normally open, and the second valve lock is in normally off, and clear water can be flowed out by the mouth of a river that overflows at pillar buoy top, and gravel can be deposited in sand storage bin; When the height of gravel rises gradually, when reaching the transparent window position, close the first valve lock, open the second valve lock, so that sand storage bin is carried out sediment outflow.After sediment outflow is complete, close the second valve lock, open the first valve lock, desander can normally use.The utility model is set up transparent window, and the convenient height of observing the inner gravel of desander can effectively be held the sediment outflow time, and the storage sand removing device of setting up can reduce the sediment outflow number of times, reduces labour intensity, avoids water body to run off, and then reduces economic loss.

The utility model is suitable as desander, is installed on the pumping line place of underground water fetching device.

Description of drawings

Below in conjunction with drawings and the specific embodiments, the utility model is done further to describe in detail.

Fig. 1 is the overall structure schematic diagram of the utility model embodiment.

In figure: 1, overflow the mouth of a river; 2, water inlet; 3, pillar buoy; 4, the first valve lock; 5, sand storage bin; 6, second valve lock; 7, transparent window; 8, conically shaped.

The specific embodiment

Embodiment

A kind of hydrocyclone, structure comprise pillar buoy 3, conically shaped 8 as shown in Figure 1.

The sidepiece of pillar buoy 3 is provided with water inlet 2, is communicated with pillar buoy 3 inner chambers, and the top is provided with and overflows the mouth of a river 1, is communicated with pillar buoy 3 inner chambers.

Conically shaped 8 is fixed on pillar buoy 3 lower ends, and its top internal diameter is identical with the internal diameter of pillar buoy 3, and center line both overlaps.The bottom of conically shaped 8 outer walls is provided with transparent window 7, and the bottom is fixedly connected with the storage sand removing device that is used for Storage and draining gravel that is communicated with its internal cavities.

The storage sand removing device comprises the first valve lock 4, sand storage bin 5, second valve lock 6.The first valve lock 4 is fixed on the lower end of conically shaped 8, and sand storage bin 5 is fixed on the lower end of the first valve lock 4, and second valve lock 6 is fixed on the lower end of sand storage bin 5.Connect firmly by bolt between the first valve lock 4 and sand storage bin 5, sand storage bin 5 and second valve lock 6.

When the utility model normally uses, the first valve lock 4 is in normally open, second valve lock 6 is in normally off, the water that is flowed into by water inlet 2 can produce strong rotation, because the density of water and sand is different, drag at buoyancy, centripetal force and fluid under the acting in conjunction of power, the clear water that density is little can rise and flow out by overflowing the mouth of a river 1, the gravel that density is large can be deposited in sand storage bin 5 along conically shaped 8 walls, when the height of gravel rises gradually, when reaching the position at transparent window 7 places, close the first valve lock 4, open second valve lock 6, so that sand storage bin 5 is carried out sediment outflow.Transparent window 7 can conveniently be observed the height of the inner gravel of this hydrocyclone, effectively holds the sediment outflow time, and the storage sand removing device can reduce the sediment outflow number of times, reduces labour intensity, avoids water body to run off, and then reduces economic loss.
