Description
Technical field
The present invention relates to a kind of lime slaking machine, relate in particular to the lime slaking machine that is suitable in a kind of alumina producing.
Background technology
In alumina producing, lime slaking machine is a kind of important equipment.Its objective is through lime slaking machine and be converted into milk of lime to lime and water through physical reaction.Used in the past lime slaking machine has very big defective.Milk of lime is because screen drum often contains a certain amount of impurity and solid lime particle, and do not reach qualified standard, and this just causes in technological process, increasing treatment facility, for example adds vibratory screening apparatus to carry out impurity screening and solid lime particle; Simultaneously, horizontal lime slaking machine floor space is big, has had a strong impact on the usable floor area in soil, more than all can increase cost of investment greatly.Horizontal lime slaking machine complex structure like structures such as the gear ring of the support roller of supporting device, transmission mechanism and bearings, on the one hand, has increased design difficulty, on the other hand, also can bring very big difficulty to maintenance, has influenced the production efficiency of lime slaking machine virtually again.
Summary of the invention
In order to solve the problems of the technologies described above the present invention a kind of lime slaking machine is provided, purpose be make that lime slaking machine is simple in structure, ashing efficient is high, save cost, enhance productivity, improve the quality of products.
Realize through following technical scheme for reaching above-mentioned purpose the present invention.
A kind of lime slaking machine is made up of following structure: the ashing groove, be provided with the feed-pipe and first upflow tube on the top of ashing groove, and be provided with agitating screw in the ashing groove, be provided with the clean-up port in the bottom of ashing slot shell.
The entrance end of described feed-pipe is provided with lime import and water-in.
Be provided with filter screen in the upper body of described ashing groove, the exit end of feed-pipe is located at the filter screen below.
Described filter screen is located at the below of first upflow tube.
Described agitating screw is connected with the transmission system at ashing groove top.
The bottom of described ashing slot shell is provided with return line.
The import of described return line is higher than the outlet that is located on the ashing groove.
Described first upflow tube is located between the upper body of ashing groove and treatment trough.
The top of described treatment trough is provided with venting port, and the top of treatment trough is provided with second upflow tube, and the bottom of treatment trough is provided with bypass outlet.
The bottom of described treatment trough is conical.
The bottom of described treatment trough is provided with second clean-up port.
The outlet of described second upflow tube is lower than the import that is located on the treatment trough.
Advantageous effect of the present invention: the present invention is simple in structure, ashing efficient high, save cost, enhance productivity, improve the quality of products, improved economic benefit.

Embodiment
Below in conjunction with accompanying drawing the present invention is done further explain, but protection scope of the present invention is not limit by embodiment.
As shown in Figure 1, a kind of lime slaking machine of the present invention is made up of 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 stated for the conventional equipment concrete structure is no longer tired, 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, and 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 invention: lime gets into 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 deposition and the physical reaction is to the upper reaches; After waiting to flow full ashing groove 3, milk of lime is through filtering net 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 deposition for 10 li at treatment trough, and impurity and particle lime precipitation are in treatment trough 10 bottoms, and 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 is to use with ashing groove 3 in order to clear up treatment trough 10 respectively with clean-up port 14.
