Described sludge pump 6 power are between 150-200 watt.
Device operation of the present utility model may further comprise the steps:
(1) utilize sludge pump 6 as power, outlet conduit divides two-way at delivery port, and one the tunnel is transported to grinding milk in the level pressure tube 3, and another road directly tangentially is back in the bucket along the bucket wall of lapping liquid bucket 5 in the position near the bucket end, form whirlpool, realized stirring certainly lapping liquid;
(2) adjust the pressure at the mouth of a river by the inclination angle that changes level pressure tube 3, thereby control the flow velocity of grinding milk;
(3) slurries in the level pressure tube 3 flow to the abrasive disk working region by outlet conduit 9, reclaim and flow to filter 7 by pipeline, flow back to lapping liquid bucket 5 after the filtration;
(4) repeat above-mentioned (1)-(3), in input channel, inject clear water after grinding work is finished to clean.
In described step (2), the position of level pressure tube 3 can be regulated between 0～80 °.
In described step (3), level pressure tube 3 top reflux line diameters are at least 15mm.
As preferred a kind of scheme: in described step (3), the same step of water inlet pipeline (1) of level pressure tube 3 all connects at a certain angle, and lapping liquid is tangentially poured in the level pressure tube, realizes from stirring.
Further, in described step (2), open refluxing opening, guaranteeing the constant voltage of whole system, thereby guarantee the lapping liquid flow speed stability on the top of the input channel of level pressure tube 3.
Further again, in described step (2), level pressure tube 3 is adjusted its inclination angle by unclamping locking nut 4, and identifies by 1 pair of inclination angle of the dial on the positioning tube support 2, can be used for demarcating the flow velocity of certain liq.The inclination angle refers to the angle of level pressure tube 3 and vertical direction, and its adjustable range is 0 °-80 °.
In the pipeline of described system, place filter 7, with the interception larger particles, prevent that bulky grain from flowing back to lapping liquid bucket 5, causes damage to workpiece.
The utility model uses sludge pump 6 as solution feed pump, utilizes the inclination angle of level pressure tube 3 to change the flow velocity of controlling grinding milk, designs the certainly stirring of particular interface with the realization grinding milk, and reflux line is set to realize the constant voltage of whole system.Sludge pump 6 adopts motor-driven, can the pumping solids content reach 56% mixed serum.
The utility model uses sludge pump pumping grinding milk can effectively improve pumped mass, reduces the wearing and tearing to pump; Design can be regulated the level pressure tube with control lapping liquid flow velocity, thereby realizes the valveless design; The design particular interface can be realized the stirring certainly of grinding milk.
