Description

A kind of sand washer of washing again function that reclaims with fine sand
Technical field
The utility model relates to sand washer technical field, more specifically says a kind of sand washer of washing again function that reclaims with fine sand.
Background technology
Sand washer is that the method by gravity floatation is gone out the mud powder (being less than the particle of 75 microns) being contained in sand with water rinse, sand is fished for out and effectively deliver to after dehydration the machinery of definite position.
At present common sand washer has bucket wheel formula, carrier bar bucket type, spiral etc.If Fig. 1 and Fig. 2 are a bucket wheel formula sand washer of recording in the middle of patent 201320597916.0, mainly formed by riffler 1, dynamical system 2, bucket wheel 3, discharge outlet 4.Its general principle is that the sand after screening follows a large amount of water to pour the front portion of sand washer riffler 1, and the rear portion of riffler 1 has discharge outlet 4, sand under the drive of current in riffler 1 by front portion to rear motion, be lowered into the bottom of riffler 1 at Action of Gravity Field at this process medium sand, and the tiny mud powder being contained in sand is gone out from discharge outlet 4 rinsings under the drive of current, dynamical system 2 drives bucket wheel 3 by direction as shown slow circumvolve, the sand that sinks to riffler 1 bottom is picked up, the bottom of bucket wheel 3 is that screen cloth with holes can effectively filter out the water in the sand picking up, bucket wheel 3 after desliming and the finished sand that filters water be discharged at the outside (generally being connect away by conveyer belt) of riffler 1 afterbody.
Due to washing in husky production, the accurate servo-actuated control of sand material clay content heterogeneity and water consumption is difficult, is therefore less than below 75 microns in mud powder washing off, understands some fine sand and also from discharge outlet 4, is discharged and run off.The flow process of riffler 1 is short, discharge is large, and the fine sand amount of discharge will be many.The loss of fine sand can make the modulus of fineness chap of finished sand, and grating variation makes the particle content of discharging water body increase formation deposition and pollute simultaneously.
Utility model content
The purpose of this utility model is to solve the fine sand of discharging from sand washer discharge outlet can not reclaim the technical problem of washing again, provide a kind of structural manufacturing process simple, manufacture supporting convenience, can effectively improve the grating of finished sand, increase output, reduced widely again particle content in the sewage discharging, that has reduced environmental pollution pressure reclaims with fine sand the sand washer of washing again function.
In order to reach above object, the utility model is achieved through the following technical solutions: a kind of sand washer of washing again function that reclaims with fine sand, comprise sand washer, it is characterized in that, the delivery port connection of described sand washer is provided with a water leg, the top of described water leg is provided with the bypass channel leaving of being separated by with it, the bottom of described bypass channel is provided with the connected entrance of the described water leg of a connection, in described connected entrance, be provided with a flow divider, on the upper side wall of described bypass channel, be provided with a clear water discharge outlet, the lateral wall of described bypass channel has set up a hydrocyclone by the upper position, the bottom of described water leg is provided with a sewage pump, described sewage pump is connected with the water inlet of described hydrocyclone by conduit, the Graceful mouth of a river of described hydrocyclone passes into the top of described bypass channel by conduit, the concentrate outlet of described hydrocyclone passes into the charging aperture of described sand washer by conduit.
The utility model designs increase fine sand recovery system and forms the sand washer with fine sand recovery function on the basis of bucket wheel sand washer, can effectively reclaim the grating that is greater than the fine sand (about rate of recovery 80-90%) of 100 microns and had both improved finished sand, increase output, reduce widely again particle content in the sewage discharging, reduce the pollution pressure to environment, achieved many things at one stroke.
As preferably, described hydrocyclone comprises an eddy flow housing, in described eddy flow housing, have one and dock one on the other by cylindrical section inner chamber and conical section inner chamber the disengagement chamber forming, the water inlet of described hydrocyclone is arranged on the side of described cylindrical section inner chamber and is tangent with sidewall, the Graceful mouth of a river of described hydrocyclone is arranged at the top of described cylindrical section inner chamber, and the concentrate outlet of described hydrocyclone is arranged at the bottom of described conical section inner chamber.
The core component of hydrocyclone is conical section inner chamber, whole cyclone is made by steel plate or other high-abrasive material, need sewage to be processed under water-aspirator pressure effect, send into hydrocyclone from tangential direction (to recommend 5-12 meter per second) at a high speed, enter the sewage of hydrocyclone along wall generation High Rotation Speed.Under centrifugal action, solid particle is thrown to eddy flow wall, is subject to the frictional force of eddy flow wall, the gravity of self and the effect of current, and solid particle drops to the dope slag-drip opening place of conical lower portion and discharges thus with eddy flow.Because sewage is made High Rotation Speed along wall, in current cyclone, be formed centrally low pressure, clear liquid after treatment forms the secondary spiral stream on screw in the axle center of cyclone, and is discharged by the clear liquid delivery port of cyclone central upper portion, clear liquid delivery port should connect with atmosphere, prevents siphon.
As preferably, sand washer is bucket wheel formula sand washer, and its structure is made up of riffler, dynamical system, bucket wheel, charging aperture and discharge outlet, and wherein the bottom of bucket wheel is screen cloth with holes.
Certainly sand washer can also be selected carrier bar bucket type and spiral two kinds, but structure, the structure of modification of bucket wheel formula is more prone to.
As preferably, water leg and riffler are integral type syndeton.
Make fine sand reclaim the system of washing be again combined with sand washer more close, be better convenient to unified management.
Beneficial effect: (1) the utility model is simple in structure, sewage pump, hydrocyclone all have the product of standard for selecting, and features simple and practical process, makes supporting convenience.
(2) sand washer and fine sand reclaim that to wash system in combination convenient again, and sand washer not only can be used alone but also use capable of being combined, especially can carry out upgrading very easily to existing sand washer.
(3) sand washer and fine sand reclaim and wash system next-door neighbour layout again, and compact conformation, takes up an area little.
