Embodiment Construction

[0025] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0026] An automatic pulping system includes a primary stirring device and a secondary stirring device (not shown in the figure); the primary stirring device and the secondary stirring device are connected through a pipeline 1 .

[0027] A first-stage mixing device, including a mixing bucket 2; the mixing bucket 2 is divided into a lower ash area 21, a convection mixing area 22, and an upper water area 23 from top to bottom in the height direction; the top of the lower ash area 21 has a lower ash port 211; The mixing zone 22 has a slurry outlet 221; the upper water zone 23 has a water inlet 231; in the mixing tank 2, there are multiple sets of stirring fins, and the rotating shafts of the multiple sets of stirring fins are coaxial. Amo...

Abstract

The invention provides a stirring device. The stirring device comprises a stirring barrel, wherein the stirring barrel is divided into an ash discharging region, a convection mixing region and a water feeding region from top to bottom in the height direction; an ash discharging opening is formed in the top of the ash discharging region; the convection mixing region is provided with a slurry outlet; the water feeding region is provided with a water inlet; the water inlet is positioned in a side wall of the lower end of the stirring barrel; a plurality of groups of stirring fins are further arranged in the stirring barrel; rotating shafts of the different groups of the stirring fins are coaxial; the uppermost group of stirring fins are forward spinning stirring fins while the rest groups of stirring fins are reverse spinning stirring fins; the forward spinning stirring fins are positioned in the ash discharging region; and the reverse spinning stirring fins are positioned in the water feeding region. Compared with the prior art, the stirring device has the advantages that the forward spinning stirring fins and the reverse spinning stirring fins are designed in the stirring barrel, the convection mixing region is formed between the forward spinning stirring fins and the reverse spinning stirring fins, in a rotating process, the forward spinning stirring fins accelerate sinking of cement ash, the reverse spinning stirring fins increase water feeding speed, therefore, deposited large particles are reduced, and the strong convection mixing region is formed nearby the slurry outlet.

Description

technical field [0001] The invention relates to the technical field of mining grouting, in particular to a stirring device and a stirring system for manufacturing cement slurry. Background technique [0002] The supporting first-stage mixing is mainly for grouting projects with small flow, low specific gravity and short grouting duration. [0003] When the proportion of the slurry reaches 1.24 (water-cement ratio 2.5:1) in the pulping process, there will be problems such as blockage of the first-level "stirring tank", flooding of ash and uneven mixing, which cannot meet the requirements of the project on the proportion of slurry ; In addition, problems such as centrifugal pump impeller blockage and poor water supply appear after long-term continuous injection of low specific gravity grout, which cannot meet the requirements of continuous high-strength grouting. Contents of the invention [0004] The object of the present invention is to solve the defects of centrifugal pu...
