Description
Technical field
A kind of shield quarrying case is the utility model is related to, more particularly to a kind of slurry shield stirring and screening quarrying case.
Background technology
Slurry balance shield is worn because the advantages such as its unique high workload pressure, the control of face accurate pressure are widely used in
In river, constructing tunnel over strait, muddy water circulation system undertakes the important function of slurry balance shield dispatch dregs, wherein quarrying case cloth
Put before the P2.1 slurry pumps of muddy water circulation system, diameter in plasma discharge slurries can be filtered out and pass through particle diameter more than slurry pump maximum
Stone, prevent major diameter stone holddown, block rear portion pipeline, avoid slurry pump from being stopped, ensure the normal of circulation system
Operation, therefore case of quarrying is the extremely important part of circulation system.Tradition quarrying case is divided into three types：
1）Falling rocks case：The falling rocks case sets the casing of a constant volume, stock inlet and thick liquid discharge mouth all positions below main discharge pipe
In casing top, casing rear portion is provided with grid with pipeline junction, can limit major diameter stone and enter follow-up pipeline, this structure
Falling rocks case is filled up by various diameter stones, mud after form causes the operation of circulation system short time, causes circulation system follow-up
Major diameter stone collection rate is low during operation, and falling rocks case clogging occurs often, influences construction speed.
2）Vertical gratings formula quarrying case：The quarrying case is arranged on plasma discharge pipeline, stock inlet and grout outlet in tank ends,
Grid is arranged vertically in the middle part of casing, drives stone, dregs small particle stone by grid to be present and hindered by mud speed rate
Before being interposed between grid, and the quarrying case region conveying blind area of grid front portion is larger, causes grid front area by the stone of various diameters
Block, clay, which block, even to be blocked, and influences the normal operation of muddy water circulation system.
3）HORIZONTAL PLAID grating quarrying case：Using horizontally disposed, stock inlet exists the quarrying cell grid in grid top, grout outlet
Grid bottom, the percent of pass of the quarrying case are appointed so slightly larger than vertical gratings formula quarrying case and accumulation minor diameter dregs stone be present
Blind area, also there is multiple stones overlap joint and block grids, cause grid flow area to reduce, have to unpack when blocking serious into
Row cleaning, influence muddy water circulation system continuously operation and normal work.
The utility model patent that existing authorized announcement date is 2012.07.04, Authorization Notice No. is CN202300416U discloses
A kind of quarrying case in shield machine:The casing being connected including both ends with mud pipe, casing is interior to be provided with rotary shaft, and rotary shaft is provided with
