Description
Technical field
The utility model relates to a kind of downflow weir of thickener, relates to a kind of downflow weir of central transmission concentrator or rather.
Background technology
The inspection target of thickener mainly contains 2 points, and one is overflow water quality, and two is underflow density and treating capacity.Downflow weir is the important component part of concentration basin, not only controls the height of the water surface in thickener, and has a direct impact the water quality of uniform flow, overflow water in thickener.The downflow weir of large-scale thickener is all reinforced concrete structure usually, and the downflow weir circumference discrepancy in elevation differs greatly.When the circumference height of downflow weir is uneven, overflow water circumferentially a certain angle can overflow pond body, other angles then do not have overflow water to flow out, there is the angle water velocity of overflow water very fast, some material has little time precipitation and just flows out pond body, overflow water solid content is increased, and underflow density reduces production capacity and does not reach designing requirement.In the body of pond, material to be processed is become because water (flow) direction is guided by original circumferentially uniform settlement and concentrates on a certain circumferential angle sedimentation simultaneously, and after a large amount of materials to be processed concentrates on a certain angle at the bottom of pond, the pond substrate bed of material can be extremely uneven.In the scope not having an overflow water, pond initial bed thickness is much smaller than normal operating conditions thickness of feed layer; There is initial bed thickness in pond in the angular range of overflow water then much thick than normal operating conditions thickness of feed layer.Pond substrate material arrangement unequal loading is cyclically-varying, thus makes mud scraper unbalance stress constantly carry rake to fall rake, duty extremely unstable.
Summary of the invention
The purpose of this utility model is to overcome the overflow sloping plate unit that the deficiencies in the prior art provide a kind of central transmission concentrator, solve the problem that the existing large-scale concentration basin downflow weir circumference discrepancy in elevation differs greatly, make that material to be processed uniform settlement at the bottom of pond, equipment working state are stable, overflow water solids content reduces, underflow density and designed capacity ensured.
The utility model is for achieving the above object, and the technological means adopted is: comprise concrete basin, delivery port, characterized by further comprising ore deposit circle, organizes overflow launder, channel-section steel more, organizes sloping plate unit more, swash plate support; Described concrete basin is reserved with multiple delivery port at installation many groups overflow launder place; Described hold together ore deposit circle fix with swash plate support welding, top higher than overflow launder, bottom lower than swash plate; Many groups overflow launder is uniformly distributed along holding together ore deposit circle, one end of each overflow launder with hold together ore deposit enclose be connected, the other end reserves the mouth of a river with concrete basin and is connected; Often organize sloping plate unit comprise several swash plates, radially arrange be inserted on swash plate support; Described overflow launder channel-section steel is connected with pond body pre-embedded steel slab I, and top, overflow launder two sides has serrate slot; Described swash plate support is weldment, welds on pond body pre-embedded steel slab II.
As shown from the above technical solution, the utility model overflow launder extended length, spillway discharge increase; Overflow, underflow density obviously improve, and improve thickening efficiency; Production capacity improves; Drive motors current stabilization, puies forward rake frequency and reduces.
Accompanying drawing explanation
Fig. 1 is partial front elevation view of the present utility model.
Fig. 2 is overall top view of the present utility model.
In figure, 1. hold together ore deposit circle, 2. overflow launder, 3. swash plate, 4. channel-section steel, 5. pre-embedded steel slab I, 6. delivery port, 7. concrete basin, 8. swash plate support, 9. pre-embedded steel slab II.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, 2, the utility model comprises holding together ore deposit circle 1, overflow launder 2, organizes sloping plate unit, channel-section steel 4, pre-embedded steel slab I 5, delivery port 6, concrete basin 7, swash plate support 8, pre-embedded steel slab II 9 etc. more.Described hold together ore deposit circle 1 be welded and fixed with swash plate support 8, hold together ore deposit and enclose 1 top higher than overflow launder 2, bottom lower than swash plate 3.Many groups overflow launder is uniformly distributed along holding together ore deposit circle 1, one end of each overflow launder 2 with hold together ore deposit and enclose the delivery port 6 that 1 is connected, the other end is reserved with concrete basin 7 and connect, the centre, top of overflow launder 2 and two sides channel-section steel 4 are connected with pond body pre-embedded steel slab I 5, and top, overflow launder 2 two sides has serrate slot.Concrete basin 7 is reserved with multiple delivery port 6 at installation many groups overflow launder 2 place.Often organize sloping plate unit to comprise several swash plates 3, arrange in radiation and be inserted on swash plate support 8.Swash plate support 8 is weldment, welds on pond body pre-embedded steel slab II 9.
The operation principle of existing apparatus: raw ore slurry distributes out from the distribution device of thickener, slowly sink according to sedimentation theory, in this infall process, heavy particle sinks down into rapidly at the bottom of pond, little particle is suspended in body centre, pond and the impact of the new ore pulp constantly incorporated moves, directly overflow downflow weir and discharge pond body, overflow water concentration is higher does not reach designing requirement.
Operation principle of the present utility model:
The utility model have employed ore deposit circle 1, overflow launder 2 structure, hold together ore deposit and enclose 1 top higher than overflow launder 2, the granule be suspended in the middle of pond body can be blocked does not allow it directly enter overflow launder 2, but slowly sinks down into ore deposit and enclose 1 time edge, changes the direction of motion and floats and enter Duo Zu sloping plate unit district.Do not have the impact of heavy material in sloping plate unit district, subsidence velocity is accelerated to be separated with clear water rapidly to fall on swash plate, automatically disengages swash plate and fall at the bottom of pond after reaching certain thickness.Isolated clear water enters overflow tank body from the profile of tooth mouth of many group overflow launders, flows into water leg discharge by the delivery port that pond body is reserved.Be that unified processing be arranged on same level in owing to organizing overflow launder more, ensure that same liquid level, the overflow launder making clear water can flow into the radiation of many groups equably to arrange, decreases the turbidity of overflow water, ensure that the water quality of overflow water.
Organize overflow launder owing to have employed, overall overflow length is far longer than original downflow weir 3 ~ 4 times more, and many groups sloping plate unit of increase expands desilting area thus improves treating capacity, improves underflow density.Many groups overflow launder is along pond body circumference uniform fluid flow, and there is not material by current guiding function, material can evenly sink at the bottom of pond, and the pond substrate bed of material is even, harrow frame stable working state, decreases and puies forward rake frequency, and drive motors current stabilization extends the thickener life-span.
The above; be only detailed description of the invention of the present utility model, be not limited thereto, be anyly familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.
