Description

The sedimental overflow mechanism of a kind of energy Automatic clearance reservoir

Technical field

The utility model relates to the sedimental overflow mechanism of a kind of energy Automatic clearance reservoir, belongs to plumbing equipment technical field.

Background technology

Industrial circle recirculating cooling water system is generally made up of reservoir, the water pump being arranged in reservoir, cooling tower or heat exchanger and the bleed off pipe that is fixed on reservoir inside; Reservoir is for ensureing normal water storage function, generally be provided with overflow liquid level, normal level and low liquid level three with reference to liquid level, as shown in Figure 1, overflow liquid level is the highest liquid level of reservoir, when reservoir water level is higher than overflow liquid level, by bleed off pipe, unnecessary water is discharged reservoir, to ensure the normal retaining of reservoir; Normal level is below overflow liquid level, more than low liquid level, and the height of normal level embodies the adjustment water reservation of reservoir; Low liquid level is the lowest limit liquid level of reservoir, when lower than low liquid level, water pump is easily caused not go up water, or cause the deposits such as columns base mud entered water system by water pump suction and cause device damage, it is general when liquid level is down near low liquid level, need termination of pumping or carry out water replenishment, maintaining reservoir liquid level more than low liquid level.

Existing reservoir defect is: bleed off pipe water inlet is generally positioned at top or the top of reservoir, usually be all undertaken by reservoir top to reservoir moisturizing, top water quality is better, when overflow occurs, the high-quality water on top enters sewer by bleed off pipe, and the silt and other sediment being arranged in columns base is still present in reservoir, cause the waste of high-quality water resource; Meanwhile, reservoir is in recycling for a long time, and basic sediment frequently must carry out emptying cleaning, and emptying cleaning needs shutdown operation, has a strong impact on normal rhythm of production, meanwhile, adds cleaning labour cost.

Utility model content

Technical problem to be solved in the utility model is to provide the sedimental overflow mechanism of a kind of energy Automatic clearance reservoir, by the improvement to bleed off pipe, deposit while utilizing siphon principle to realize reservoir overflow in suction outer row partial storage pond, prevent deposition to harden solidification, extend reservoir cleaning cycle, stable water supply water quality.

The sedimental overflow mechanism of a kind of energy Automatic clearance reservoir, comprise the bleed off pipe being fixed on reservoir inside, its improvements are: described bleed off pipe comprises water absorbing section, draining section and linkage section, linkage section is positioned at the overflow liquid level place of reservoir, two ends connect water absorbing section and draining section respectively, overfall is opened on linkage section, and water absorbing section is connected with horn-like water absorber away from the end of linkage section, and its horn mouth plane is near columns base; The outlet of draining section is lower than reservoir bottom surface; As 350mm≤water absorbing section diameter ﹤ 1000mm, overflow diameter is 20mm, and as water absorbing section diameter >=1000mm, overflow diameter is 0.02 times of water absorbing section diameter.

The above-mentioned sedimental overflow mechanism of one energy Automatic clearance reservoir, the horn mouth plane of described horn-like water absorber is parallel with reservoir bottom surface, and horn mouth plane is 300mm ~ 700mm to the vertical distance of reservoir bottom surface; Described draining section is exported to the vertical distance >=0.8m of reservoir bottom surface.

The above-mentioned sedimental overflow mechanism of one energy Automatic clearance reservoir, the most narrow diameter of junction closing in section of described horn-like water absorber and bleed off pipe water absorbing section is 0.6 ~ 0.8 times of water absorbing section diameter; Horn-like water absorber horn mouth diameter is 2 ~ 3 times of water absorbing section diameter; Draining section diameter is 1.2 ~ 1.5 times of water absorbing section diameter.

The course of work of the present utility model is: reservoir flooding velocity is less than reservoir moisturizing speed usually, when exceeding overflow liquid level to moisturizing in reservoir, overfall starts outer draining, now maintenance moisturizing, because the design of the utility model overflow diameter can ensure that overflow flow velocity is much smaller than moisturizing speed, when the water surface exceedes overfall height, realize the sealing of water liquid to overfall, when being full of water in overflow mechanism, the draining section of bleed off pipe, link and water absorbing section form syphon, due to the pressure differential that the absolute altitude at device two ends is formed, the silt and other sediment suction being positioned at columns base is realized to discharge reservoir, the horn-like water absorber adopting reducing to be connected with water absorbing section can improve the flow velocity of reducing junction, the vertical distance of horn-like water absorber horn mouth plane and reservoir bottom surface is that 300mm ~ 700mm can avoid occurring that silt " puies forward " phenomenon motionless, the outlet of draining section and the difference in height >=0.8m of horn-like water absorber ensure sedimentally to arrange outward smoothly, and draining section diameter is that 1.2 ~ 1.5 times of water absorbing section diameter can accelerate sedimental outer row, realize the quick decline of reservoir liquid level while siphon principle arranges basic sediment outside, when liquid level drops to overflow liquid level, overfall spills, and air enters bleed off pipe inside, and siphon drainage destroys, and draining stops.

The beneficial effects of the utility model are:

The utility model utilizes siphon principle to realize arranging the sedimental overflow of columns base outward, effectively prevent deposition to harden solidification, the waste of reservoir top high-quality water resource has been stopped while ensureing reservoir normal level, the sedimental emptying cleaning cycle of effective prolongation columns base, save labour cost, ensure that production direct motion; The utility model structure is simple, widely applicable, the cheap easily construction of transformation, and sludge discharge effects of drawing water is remarkable, effectively can control the content of sedimentation in reservoir during overflow, realizes stablizing of reservoir long-period stable operation and water supply quality excellent.
