Specific embodiment
The present invention is further illustrated below by the mode of embodiment, but does not therefore limit the present invention to the reality
It applies among a range.
It is as shown in Figure 1 the structural schematic diagram of mud sand filter 100 of the present invention.The mud sand filter 100 include shell 1,
Discharge pipe 2, filter mantle 4 and slurry pump 5, shell 1 is interior to form inner space 11, and the bottom 12 of shell 1 is equipped with sand discharge outlet 13, shell
The top 14 of body 1 is equipped with mud inlet 15, and mud inlet 15, sand discharge outlet 13 are connected with inner space 11;The two of discharge pipe 2
End is respectively entrance 21 and outlet 22, and the entrance 21 of discharge pipe 2 protrudes into inner space 11;Filter mantle 4 is made of filter screen, mistake
Filter bowl 4 surrounds the entrance 21 of discharge pipe 2;Slurry pump 5 is connected with discharge pipe 2, and slurry pump 5 is used for the mud in discharge pipe 2
Slurry is discharged from the outlet of discharge pipe 2 22.
The mud sand filter 100 is put into mud-filled mud pit, the mud upper positioned at mud pit is from mud
Import 15 enters in the inner space 11 of shell 1, and mud is discharged after the filtering of filter mantle 4 from the outlet of discharge pipe 2 22, and filters
The biggish silt of the particle to get off is discharged from sand discharge outlet 13.
Since mud precipitates in mud pit, the impurity of the mud upper positioned at mud pit is less, and mud inlet 15 is set
It is placed in the top 14 of shell 1, makes the mud less into the mud impurity of the inner space 11 of shell 1.In this way, filtered
The impurity of mud is less, better effect.In order to reach optimal filter effect, the inside that filter mantle 4 is vertically arranged at shell 1 is empty
Between 11 centre.
As shown in Figure 1, mud sand filter 100 further includes two stirring blades 6 and driving portion 7, stirring blade 6 is located at shell
In 1 inner space 11, driving portion 7 is connected with stirring blade 6, and driving portion 7 drives stirring blade 6 empty in the inside of shell 1
Between stir in 11.Stirring blade 6 stirs the mud in the inner space 11 of shell 1, so that mud generates centrifugal force, makes mud
In the biggish silt of particle be thrown on the inner wall in inner space 11 by centrifugal force.The biggish silt of particle is along the inner wall surface
It slides, after 13 discharge of sand discharge outlet, sinks in mud pit.And clean mud converges to centre, passes through row into filter mantle 4
Pipe 2 is starched to flow out.
Wherein, driving portion 7 is driving motor 71, and stirring blade 6 is fixed in the rotation axis 72 of driving motor 71.Driving electricity
The rotation axis 72 of machine 71 rotates, so that stirring blade 6 be driven to stir the mud in the inner space 11 of shell 1.
For the mud slurry uniform stirring in the inner space 11 by shell 1, stirring blade 6 is around the inner space of shell 1 11
Central axis rotation.
The quantity of stirring blade 6 can be one, but in order to reach preferable effect, the quantity of stirring blade 6 is at least
It is two, and multiple stirring blades 6 are symmetric.In this way, optimal separation effect can be reached with uniform stirring mud
Fruit.
As shown in Figure 1, the diameter of the inner peripheral surface of the bottom 12 of shell 1 gradually reduces from top to bottom, the lower end surface of bottom 12
For sand discharge outlet 13.In this way, the either silt that filters down of filter mantle 4, is still stirred blade 6 and is thrown in inner space 11
Inner wall on silt, can successfully from sand discharge outlet 13 discharge.
As shown in Figure 1, mud sand filter includes inlet pipe 8, inlet pipe 8 is connected with the mud inlet 15 of shell 1.Into slurry
Pipe 8 enters mud in the inner space 11 of shell 1 and plays guiding role.
As shown in Figure 1, mud sand filter includes support frame 3, support frame 3 is fixed on the lower section of shell 1.Support frame 3 plays
The effect of supporing shell 1 and associated components, mud sand filter are placed in the bottom of mud pit by support frame 3.
As shown in Figure 1, discharge pipe 2 includes interconnected stereoplasm tube 23 and soft pipe 24, stereoplasm tube 23 is far from soft pipe
24 one end is the entrance 21 of discharge pipe 2, and the one end of soft pipe 24 far from stereoplasm tube 23 is the outlet 22 of discharge pipe 2.Stereoplasm tube
23 are made of hard material, and soft pipe 24 is made of soft material.One section close to filter mantle 4 uses stereoplasm tube 23, stereoplasm tube
23 diameter remains unchanged, it is ensured that the circulation after filtering slurry.And one section rearward uses soft pipe 24, soft pipe 24 can
Arbitrarily to change shape, it is suitable for the demand of different construction sites, different mud pits.
As shown in Fig. 2, being included the following steps using the construction method of above-mentioned mud sand filter 100:
1) the first mud pit 200 and the second mud pit 300 are set, are stored with unfiltered mud in the first mud pit 200;
2) mud sand filter 100 is placed in the first mud pit 200, the mud inlet 15 of shell 1 is located at the first mud
The liquid level face of the mud in pond 200 is hereinafter, the outlet 22 of discharge pipe 2 stretches in the second mud pit 300;
3) start slurry pump 5, by the mud in the first mud pit 200 again from the outlet of discharge pipe 2 after the filtering of filter mantle 4
22 discharges, the biggish silt of the particle filtered down are discharged from sand discharge outlet 13;While filter mantle 4 filters, stirring blade 6
By the mud agitation in the inner space 11 of shell 1, the biggish silt of the particle in mud is made to be thrown to inner space by centrifugal force
It on 11 inner wall, then slides along inner wall, from 13 discharge of sand discharge outlet.
