Description

A kind of high-efficiency swirl-type desander
Technical field
The utility model belongs to desanding technical field, is specifically related to a kind of high-efficiency swirl-type desander.
Background technology
At present, conventional industry, agriculture and civilian spiral-flow type desanding device is generally installed on well exit, its operating principle is the principle according to centrifugal sedimentation and density contrast, when current under pressure from desanding water inlet with tangential access arrangement after, produce strong rotary motion, because sand is different with water density, the centrifugal force be subject to, centripetal force, the size such as buoyancy and fluid drag is also different, by centrifugal sedimentation effect, a low-pressure area is produced in the middle of cone, form a gas column, cause vacuum, play swabbing action, make low density liter waterborne, discharged by delivery port, 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, desander 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, disposal ability 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 delivery port, cause desanding unclean, affect desanding effect.Current solution installs well strainer again in desander rear end, secondary filter is carried out to water, but equipment and maintenance cost will be increased like this, and well strainer 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 high-efficiency swirl-type desander, and it possesses compact conformation, desanding efficiency is high, cost of production is low feature.
For achieving the above object, technical solution adopted in the utility model is as follows:
A kind of high-efficiency swirl-type desander, it comprises rotational flow separation tank and sand storage tank, described rotational flow separation tank is divided into upper prop tank and lower cone tank, the lower outlet of described lower cone tank is connected with sand storage tank, the tank skin of described upper prop tank offers tangential inlet pipe, the axle center of described tank deck is to being provided with overflow outlet, the bottom of described overflow outlet is connected with well strainer, described well strainer comprises the connector be connected with described overflow outlet and the spinning body be connected with described connector, 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, reinforcing rib 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 radial direction mutually interior extension is connected with the axle collar, described connector inwall is provided with bracing frame, axis of rotation is provided with bottom support frame as described above, the described axle collar is loaded on described axis of rotation by bearing holder (housing, cover), the free end of described axis of rotation is provided with retaining part.
Further improve as the utility model, described connector upper inside wall is provided with connection internal thread, and the bottom outer wall of described overflow outlet is provided with and the described connection external screw thread being connected internal thread and matching.
Further improve as the utility model, support frame as described above is made up of with the support bar for being connected described fixed axis and connector inwall fixed axis, and described support bar is two or more.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is owing to being provided with well strainer, when water is flowed out by overflow 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 desander inside generation, helical wing plate drives spinning body to rotate along axis of rotation, 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, possesses compact conformation, desanding efficiency is high, cost of production is low feature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of well strainer of the present utility model;
Fig. 3 is the top view of well strainer of the present utility model;
In the drawings: 1 knockout drum, 2 sand storage tanks, 3 upper prop tanks, 4 times cone tanks, 5 tangential inlet pipes, 6 overflow outlets, 10 well strainers, 11 connectors, carrier ring, 14 filter sand nets, 15 times carrier rings, 16 reinforcing ribs, 17 helical wing plate, 18 flabellums, 19 axle collars, 20 bracing frames, 21 axis of rotation, 22 retaining parts, 23 fixed axis, 24 support bars on 12 spinning bodies, 13.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed further describing is carried out to the utility model.
As Fig. 1, shown in 2 and 3, a kind of high-efficiency swirl-type desander, it comprises rotational flow separation tank 1 and sand storage tank 2, described rotational flow separation tank 1 is divided into upper prop tank 3 and lower cone tank 4, the lower outlet of described lower cone tank 4 is connected with sand storage tank 2, the tank skin of described upper prop tank 3 offers tangential inlet pipe 5, the axle center of described tank deck is to being provided with overflow outlet 6, the bottom of described overflow outlet 6 is connected with well strainer 10, described well strainer 10 comprises the connector 11 be connected with described overflow outlet 6 and the spinning body 12 be connected with described connector 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, reinforcing rib 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 radial direction mutually interior extension is connected with the axle collar 19, described connector 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 fixed axis 23 and connector 11 inwall fixed axis 23, described support bar 24 is four.Be provided with axis of rotation 21 bottom the fixed axis 23 of support frame as described above 20, the described axle collar 19 is loaded on described axis of rotation 21 by bearing holder (housing, cover), and the free end of described axis of rotation 21 is provided with retaining part 22.Described connector 11 upper inside wall is provided with the connecting thread be connected with desander delivery port.
