Specific embodiment
Below by specific embodiment, technical scheme of the present invention will be described in further detail.
Embodiment 1
As shown in Figure 1, a kind of grading plant for realizing hindered bed separator overflow desliming, including classification boundary 8 and bracket, it is described
It is classified boundary 8 and is used to cut on overflow layer separation, for fixing the classification boundary 8, the classification boundary 8 is located at the bracket
The top on overflow layer overflow boundary 9 forms vertical gap with the overflow layer overflow boundary 9, and the classification boundary 8 is cut described
In overflow layer.
When concrete application, the staving upper edge self-assembling formation overflow layer overflow boundary 9 of hindered bed separator (TBS) 10,
The reason is that the bucket wall of staving constitutes leading for bleed-off fluid because bleed-off fluid flows up under the promotion of upward disturbance fluid
To structure, after reaching bucket wall upper end boundary, bleed-off fluid loses support, starts outside overflow, therefore, the overflow layer overflow side
The definition on boundary 9 comes therefrom.
In the actual process, bleed-off fluid directs out spilling from overflow layer overflow boundary under the promotion of disturbance fluid
Still for minority, most of fluid can also move upwards a distance, like the water surface of boiling, be based on this principle, will point
Grade boundary 8 is arranged in beyond certain specific location above overflow boundary, depending on the particle size which is classified as required,
Overflow portion beyond classification boundary 8 is from the outside overflow in top on classification boundary, without departing from the overflow portion on classification boundary from perpendicular
To the outside overflow in gap.
In this embodiment, since classification boundary 8 need to accurately separate first-class fluid, excessive vertical sky cannot be occupied
Between, therefore the thickness on the classification boundary must be sufficiently thin, and thin-slab structure can be used and be inserted into bleed-off fluid, to guarantee that fluid can
Outflow, thin plate should be horizontal thin plate or outer low and inner high thin plate.
In order to preferably guarantee grading effect, and do not influence the normal work of hindered bed separator, classification boundary without departing from
The inner edge of cylinder inboard wall, effect is best when the two is vertically consistent.
Bracket is mainly used to fixed classification boundary, and therefore, without limitation, can be will be classified boundary to the concrete form of bracket
The bracket being fixed on hindered bed separator is also possible to other kinds of bracket.
Embodiment 2
As shown in Fig. 2, the present embodiment the difference from embodiment 1 is that: the classification boundary 8 is located at overflow layer overflow boundary 9
Outside equal-height position forms horizontal clearance with the overflow layer overflow boundary 9.
The principle of the program is that bleed-off fluid moves upwards one from overflow layer overflow boundary under the promotion of disturbance fluid
After section distance, since surrounding loses support, overflow around is understood, but in the process, the bleed-off fluid positioned at upper layer is overflowed
Radius it is bigger, the radius overflowed positioned at the bleed-off fluid of lower layer is relatively smaller, and using this principle, the design of classification boundary 8 is existed
The outside of overflow layer overflow boundary isometry position, and horizontal clearance is reserved, the small bleed-off fluid of partial size is covered from classification boundary,
It is split from top, the big bleed-off fluid of partial size flows away from horizontal clearance, realizes classification.
The size in gap can control the size of Cut size.
In this embodiment, it is classified due to classification boundary 8 without being inserted into bleed-off fluid, bleed-off fluid is being split place
It is to move from top to bottom, the level board or inclined plate of no thickness requirement can be used, bleed-off fluid is shut off, need to only controls the side of plank
Boundary position.
It is of course also possible to be inserted into bleed-off fluid from bottom to top using vertical thin plate, realizes and be classified, under this mode,
With the matched structure type of existing hindered bed separator, tubular structure can be ring-shaped.
Embodiment 3
In order to more easily shunt by the small size particle after classification, deflector can be connect in classification border outer.
Embodiment 4
Since the volume of hindered bed separator is larger, a complete classification boundary is not easy to manufacture, the classification boundary and described
Bracket is classified boundary by several height and submounts are surrounded and constituted, and after surrounding installation, constitutes complete classification boundary, real
Now it is classified.
Specifically, as shown in Figure 3 and Figure 4, the submounts are two risers 3, and the lower end of two risers 3 opens up card slot 4, institute
Stating sub- classification boundary is level board 1, and 1 both ends of level board are separately connected two risers 3, the inner end profile of the level board 1
It is consistent with the chamfered shape on overflow boundary 9, is arc-shaped edges 5.
Card slot 4 is for being mounted on edge on the bucket wall of hindered bed separator 10, and there are two types of forms for the position of card slot 4, and difference can
To allow the inner edge of level board to be located at outside (such as Fig. 4) at the top (such as Fig. 3) or isometry position on edge on staving, and then realize real
Apply two kinds of hierarchical forms in example 1 and embodiment 2.
Using this card slot type structure, it is easy for installation and removal, it is easier to operate.
Embodiment 5
The present embodiment is from the difference of embodiment 4: in order to adapt to different classification demands, level board 1 passes through vertical adjustment
Structure is mounted on two risers 3, specifically, can design rows of mounting hole on two risers 3, level board is by being mounted on
The adjusting of height is realized at the mounting hole of different height；Alternatively, as shown in figure 5, design vertical installation long hole 6 on riser 3,
The installation site that level board 1 is adjusted by adjusting bolt 7, realizes the adjusting of height.
Using this structure, the size of Cut size, so that it may which the height by adjusting level board 1 apart from cylinder is realized.
Finally it should be noted that: the above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, it should be understood by those ordinary skilled in the art that: still
It can modify to a specific embodiment of the invention or some technical features can be equivalently replaced；Without departing from this hair
The spirit of bright technical solution should all cover within the scope of the technical scheme claimed by the invention.
