Description
Technical field
The utility model relates to slurry shield machine machinery, particularly relate to a kind of type quarrying case of independently slagging tap from gravity.
Background technique
Slurry balance shield is worn because the advantages such as its unique high operating pressure, the control of face accurate pressure are widely used in
In river, constructing tunnel over strait, mud circulating system undertakes the important function of slurry balance shield dispatch dregs.Slush pump is mud
An important ring for the circulatory system provides power resources for whole system, but slush pump has the limitation by partial size, mud circulation
The maximum of slurry pump plays restriction effect to the grid before discharge pipe stock inlet by partial size in system, and too small grid channel is straight
It connects and results in stagnant row, setting quarrying case can effectively solve discharge pipe input end grate opening size and be passed through by slurry pump before slurry pump
The influence of partial size.Quarrying case can filter out diameter in plasma discharge slurries and be greater than stone of the slurry pump maximum by partial size, prevent big
Diameter stone holddown, blocking rear portion pipeline, avoid slurry pump from stopping working, alleviate the stagnant row of thick liquid discharge mouth, guarantee circulation system just
Often operation, so quarrying case is the extremely important component of circulation system.
The main application type of existing quarrying case has falling rocks case, vertical gratings formula quarrying case, HORIZONTAL PLAID grating quarrying case.
1. falling rocks case is no grill designs, the debris in slurries can sink to the bottom of box under gravity, hardly
Have the sieving capacity to stone partial size, and there are big partial size stones to enter thick liquid discharge mouth, there is biggish holddown risk；
2. the vertically arranged quarrying case of grid is using more, but the arrangement form of grid will certainly hinder the flowing of slurries,
And in order to increase quarrying amount, often cabinet is larger for such quarrying case, and flow velocity can reduce moment after slurries enter cabinet, this
Also it directly results in front of quarrying cell grid there are stagnant slag section, flow area can be gradually reduced in use, cause frequently to unpack
Stone is taken, construction efficiency is influenced；
3. the quarrying case of grizzly level arrangement using relatively fewer, since grizzly level is arranged, can theoretically be conducive to dregs
Pass through, but big partial size stone is accumulated once on grid, and the flow area and screening efficiency of grid will greatly reduce,
Even subsequent small particle dregs can not be also blocked after death by grid, grid will have pressure the abruptly increase even wind of booster
Danger.
All there are the following problems for above-mentioned existing quarrying case: 1. not having screening function, there are holddown risks；The area ②Rong Shi
With screening area in a cabinet, screening efficiency is low, and Rong Shi amount is poor；3. it is complicated to hold stone segment structure, unpacking, it is more difficult to slag tap；④
There are stagnant slag section, grid easily to be blocked before grid；5. influencing the fluency of circulation system there are blind area section after grid；6. in cabinet
Portion is easy accumulated slag.
Utility model content
The utility model proposes one kind independently slag tap from gravity type quarrying case, solve the problems, such as follows: it is unreliable 1. to sieve,
It is easy holddown；2. dregs is low by grid efficiency, stagnant slag before grid；3. dregs blocks grate opening, flow area falls sharply or blocks；
The area ④Rong Shi and screening area are in a cavity, and screening efficiency is poor, and Rong Shi amount is low；5. quarry is mixed with other mechanisms, deslagging
It is difficult；The problems such as 6. case of quarrying is easily stifled, quarrying of frequently unpacking, construction efficiency is low.
The technical solution of the utility model is achieved in that a kind of type quarrying case of independently slagging tap from gravity, including screening
Section, the screening section are divided into upper screening section and lower screening section by inclined grid, and upper screening section is connected to stock inlet, upper sieve
Segmentation is connected to storage stone case, and lower screening section is connected to plasma discharge section, and plasma discharge section is connected to grout outlet.
Inclined deflector is equipped in the plasma discharge section.
The deflector is located at the opposite side of lower screening section and plasma discharge section connector.
The grout outlet is located at the opposite side of deflector.
Inclined slag plate is equipped in the storage stone case.
The slag plate is located at the same side of upper screening section and Chu Shi case connector.
The storage stone case is equipped with the quick ash gate of activity installation.
The advantages of the utility model: 1. flase floor is tilting, has both been avoided that dregs blocks grate opening, moreover it is possible to high efficiency screening；②
Screening efficiency and Chu Shiliang are improved in independent screen area and the region Chu Shi；3. the risk for avoiding quarrying case from blocking completely；4. avoiding
Sieve not in place and holddown risk；5. it is simple to hold stone box structure, slag tap conveniently；6. reduce artificial unpacking scarfing cinder number and
Cost of labor guarantees the continuity and normal work of circulation system；7. deflector built in plasma discharge section effectively reduces stagnant slag blind area；
8. screening section changes of section is relatively small, relatively small in this section of slurry flow rate loss, improves slurries and take slag ability；9. plasma discharge
Contracting section design at mouthful, improves slurry flow rate, prevents stagnant row；10. flase floor is not easy to accumulate, it will not influence subsequent dregs screening, protect
Demonstrate,prove sieving capacity.
