Description

A kind of screen filter for sand separator
Technical field
The utility model belongs to desanding technical field, is specifically related to a kind of screen filter for sand separator.
Background technology
At present, conventional industry, agriculture and civilian spiral-flow type desanding device is generally installed on well exit, its principle of work is the principle according to centrifugal settling and density difference, when current under pressure from desanding water-in with tangential access arrangement after, produce strong rotary motion, because sand is different with water-mass density, the centrifugal force be subject to, centripetal force, the size such as buoyancy and fluid drag is also different, by centrifugal settling effect, a low pressure area is produced in the middle of cone, form a gas column, cause vacuum, play suction function, make low density liter waterborne, discharged by water outlet, the sand grains that density is large is discharged by the sewage draining exit of device bottom, thus reach the object of desanding.Under certain limit and condition, sand separator intake pressure is larger, except sand coarse aggregate ratio is higher, and can multiple stage parallel connection use.Its advantage is as follows: 1. structure is simple, easy and simple to handle, safe and reliable, needs hardly to safeguard.2. compared with the desanding device such as enlarged tube, baffle-box, have volume little, processing power is large, saves the advantages such as site space.3. the sand grains in water can be removed in uninterrupted water supply process.4. avoid the phenomenon that other desanding modes exist water pollution once again, desanding efficiency is high.But its shortcoming is as follows: when hydraulic pressure is less or pressure instability when, the swirl velocity produced in equipment also can correspondingly weaken or instability, can not produce enough centrifugal force and be thrown away by sand grains, sand water is mixed and flows out from water outlet, cause desanding unclean, affect desanding effect.Current solution installs screen filter again in sand separator rear end, secondary filtration is carried out to water, but equipment and maintenance cost will be increased like this, and screen filter major part needs artificial sediment outflow, and artificial sediment outflow generally needs to cut off the water, equipment use and maintenance are had an impact.
Utility model content
The purpose of this utility model is the defect overcoming prior art, provides a kind of screen filter for sand separator, and it possesses can the function of automatic sand removal, and can reach desanding effect thoroughly.
For achieving the above object, technical solution adopted in the utility model is as follows:
A kind of screen filter for sand separator, it spinning body comprising connecting joint and be connected with described connecting joint, described spinning body comprises carrier ring and filter sand net, described filter sand net is band bottom tube-like filter sand net, the upper terminal inner lining of described filter sand net is in described upper carrier ring lower end, the lower end outside of described filter sand net is lined with lower carrier ring, stiffening web is provided with between described upper carrier ring and lower carrier ring, described filter sand net outer wall is provided with helical wing plate, described upper carrier ring inwall is evenly provided with more than three flabellums, described flabellum extends radially inwardly and is connected with the axle collar, described connecting joint inwall is provided with bracing frame, turning axle is provided with bottom support frame as described above, the described axle collar is loaded on described turning axle by bearing housing, the free end of described turning axle is provided with retaining part.
Further improve as the utility model, described connecting joint upper inside wall is provided with connecting thread.
Further improve as the utility model, support frame as described above is made up of with the support bar for being connected described stationary shaft and connecting joint inwall stationary shaft, and described support bar is two or more.
Compared with prior art, the beneficial effects of the utility model are:
After the utility model is installed on the water outlet lower end of sand separator, when water is flowed out by water outlet, filter sand net can stop because filtering the sand grains only do not produced, simultaneously under the effect of the eddy flow hydraulic pressure of sand separator inside generation, helical wing plate drives spinning body to rotate along turning axle, like this, namely ensures that strainer provided by the utility model can not have an impact to water flow rotary, under the influence of centrifugal force, the sand grains being attached to filter sand net surface is thrown away ingoing stream cyclone sediment again simultaneously.Make to keep clean to ensure to stop current because sand grains blocks at sand net surface.The utility model can ensure that sand net keeps clean, removes later stage manual maintenance from, and it possesses can the function of automatic sand removal, and can reach desanding effect thoroughly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is vertical view of the present utility model;
Fig. 3 is using state figure of the present utility model;
In the drawings: carrier ring, 14 filter sand nets, 15 times carrier rings, 16 stiffening webs, 17 helical wing plate, 18 flabellums, 19 axle collars, 20 bracing frames, 21 turning axles, 22 retaining parts, 23 stationary shaft, 24 support bars on 11 connecting joints, 12 spinning bodies, 13.
Embodiment
Below in conjunction with accompanying drawing, detailed further describing is carried out to the utility model.
As illustrated in fig. 1 and 2, a kind of screen filter for sand separator, it spinning body 12 comprising connecting joint 11 and be connected with described connecting joint 11, described spinning body 12 comprises carrier ring 13 and filter sand net 14, described filter sand net 14 is band bottom tube-like filter sand net, the upper terminal inner lining of described filter sand net 14 is in described upper carrier ring 13 lower end, the lower end outside of described filter sand net 14 is lined with lower carrier ring 15, stiffening web 16 is provided with between described upper carrier ring 13 and lower carrier ring 15, described filter sand net 14 outer wall is provided with helical wing plate 17, described upper carrier ring 13 inwall is evenly provided with six flabellums 18, described flabellum 18 extends radially inwardly and is connected with the axle collar 19, described connecting joint 11 inwall lower end is provided with bracing frame 20, support frame as described above 20 is made up of with the support bar 24 for being connected described stationary shaft 23 and connecting joint 11 inwall stationary shaft 23, described support bar 24 is four.Be provided with turning axle 21 bottom the stationary shaft 23 of support frame as described above 20, the described axle collar 19 is loaded on described turning axle 21 by bearing housing, and the free end of described turning axle 21 is provided with retaining part 22.Described connecting joint 11 upper inside wall is provided with the connecting thread be connected with sand separator water outlet.
As shown in Figure 3, in use, the utility model is connected by the connecting thread matched with the water outlet of sand separator, when after the centrifugal desanding of the water in sand separator, centrally rise and when water outlet flows out, filter sand net can stop because filtering the sand grains only do not produced, simultaneously under the effect of the eddy flow hydraulic pressure of sand separator inside generation, helical wing plate drives spinning body to rotate along turning axle, under the influence of centrifugal force, sand grains is thrown away ingoing stream cyclone sediment again, go round and begin again, to reach the object of filtration.Simultaneously because sand cannot be attached to filter gauze surface, make gauze keep clean, remove later stage manual maintenance from.
The above embodiment is only preferred embodiment of the present utility model, and is not the exhaustive of the feasible enforcement of the utility model.For persons skilled in the art, to any apparent change done by it under the prerequisite not deviating from the utility model principle and spirit, all should be contemplated as falling with within claims of the present utility model.
