Description
Technical field
The utility model relates to slurry shield quarrying casees, particularly relate to a kind of roller screening type quarrying case.
Background technique
In recent years, the underground space and wear that tunnel over strait development in river is swift and violent, everything benefits from the superiority of slurry shield
Energy.In slurry shield, slush pump is very harsh to Particle size requirements are passed through, and to protect slurry pump, needs that quarrying is arranged before pump
Case.Before quarrying case is arranged in the slurry pump of muddy water circulation system, diameter in plasma discharge slurries can be filtered out and be greater than slurry pump maximum
By the stone of partial size, major diameter stone holddown, blocking rear portion pipeline are prevented, avoids slurry pump from stopping working, guarantees circulation system
The normal operation of system, so quarrying case is the very important component of circulation system.Quarrying case type used in shield is less, main
It will be for the falling rocks case of early stage and at present still in the vertical gratings formula quarrying case used.
1) falling rocks case: the cabinet of a constant volume, stock inlet and thick liquid discharge mouth all positions is arranged in the falling rocks case below main discharge pipe
In cabinet top, cabinet rear portion and pipeline junction are provided with grid, can limit major diameter stone into subsequent pipeline, this structure
Falling rocks case is filled up by various diameter stones, mud after form causes the circulation system short time to run, and causes circulation system subsequent
Major diameter stone collection rate is low when operation, and falling rocks case clogging occurs often, influences construction speed.
2) vertical gratings formula is quarried 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 cabinet, drives stone, dregs by grid by mud speed rate, but there are small particle stones to be hindered
Before being interposed between grid, and the quarrying case region conveying blind area of grid front is larger, causes grid front area by the stone of various diameters
Block, clay blocking even block, and influence the normal operation of muddy water circulation system.
3) HORIZONTAL PLAID grating is quarried case: using horizontally disposed, stock inlet exists the quarrying cell grid in grid top, grout outlet
There is accumulation minor diameter dregs stone slightly larger than vertical gratings formula quarrying case in grid lower part, the percent of pass of the quarrying case
Blind area, also there are multiple stones overlap joint blocking grids, grid flow area caused to reduce, have to unpack when blocking serious into
Row cleaning, influences muddy water circulation system continuous operation and normal work.
4) stirring and screening formula formula quarrying case: the quarrying case is horizontally disposed using Arc grid, and stock inlet is located at Arc grid
Top, grout outlet are located at Arc grid lower part, and Arc grid upper box body region is provided with stirring blade.The quarrying of this form
Case improve to a certain extent dregs by efficiency, reduce blind area of quarrying in case, disadvantage is exactly that quarrying amount is few, stirring blade
The risk being stuck is larger.
Above-mentioned four kinds conventional falling rocks/and all there are the following problems for quarrying case: 1. the percent of pass of dregs is low, not only has collected big straight
The stone dregs of the stone of diameter, remaining minor diameter is also detained in cabinet；2. quarrying cabinet all has blind area, collection is got off
Major diameter stone combine remaining dregs occur gradually blocking quarrying case the case where, occur plot ratio reduce, even blocking quarrying
Case influences the normal operation of quarrying function and circulation system；3. can not judge the interior quantity for collecting major diameter stone of case of quarrying, out
Existing major diameter stone excess situation, leads to the reduction of quarrying case flow area, influences the normal operation of circulation system；4. quarrying amount
Less, there are card stone risks；5. grate opening is easily blocked completely, slush pump is caused to be emptied.
