Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, but protection domain of the present utility model is not limit by embodiment.
As shown in Figure 1, the utility model lime slaking machine, constitute by following structure: ashing groove 3, be provided with the feed-pipe 15 and first upflow tube 7 on the top of ashing groove 3, be provided with agitating screw 5 in the ashing groove 3, be provided with clean-up port 14 in ashing groove 3 lower part of frame, the entrance end of feed-pipe 15 is provided with lime import 1 and water-in 2, be provided with filter screen 6 in the upper body of ashing groove 3, the exit end of feed-pipe 15 is located at filter screen 6 belows, and filter screen 6 is located at the below of first upflow tube 7; Agitating screw 5 is connected with the transmission system 4 at ashing groove 3 tops, and transmission system 4 is not repeated for the conventional equipment concrete structure, and ashing groove 3 lower part of frame are provided with return line 8, and the import of return line 8 is higher than the outlet that is located on the ashing groove 3; First upflow tube 7 is located between the upper body of ashing groove 3 and treatment trough 10; The top of treatment trough 10 is provided with venting port 9, the top of treatment trough 10 is provided with second upflow tube 11, the outlet of second upflow tube 11 is lower than the import that is located on the treatment trough 10, the bottom of treatment trough 10 is provided with bypass outlet 12, the bottom of treatment trough 10 is conical, and the bottom of treatment trough 10 is provided with second clean-up port 13; Bypass outlet 12 is communicated with return line 8.
The exit end of feed-pipe 15 is located at filter screen 6 belows, can reduce the generation of vaporific lime as far as possible, avoids vaporific lime to enter atmosphere from venting port 9.
Principle of work of the present utility model: lime enters and mixes the back from the water that water-in 2 is come in from lime import 1 and flows into ashing groove 3, under the stirring of agitating screw 5 to dirty, and the milk of lime behind process precipitation and the physical reaction is to the upper reaches, after waiting to flow full ashing groove 3, milk of lime is through filter screen 6, and filter screen 6 can end in 3 li of ashing grooves to impurity and oarse-grained lime.After treating that milk of lime overflows first upflow tube 7, milk of lime just flows to treatment trough 10 from first upflow tube 7, milk of lime continues precipitation for 10 li at treatment trough, impurity and particle lime precipitation are in treatment trough 10 bottoms, the milk of lime that reaches production requirement at last just flows out from second upflow tube 11, and flow into ashing grooves 3 from return line 8 again after still containing small amount of impurities and particle milk of lime and just flowing out from bypass outlet 12, repeat above process again.Second clean-up port 13 and clean-up port 14 are in order to clear up treatment trough 10 and 3 uses of ashing groove respectively.
