Abstract
The utility model relates to a safety overflow device of condensation water recycle machinery. The safety overflow device comprises a barrel body, the upper end of the barrel body is communicated with the top portion of a condensation water tank, the lower end of the barrel body is provided with a drain pipe, a floating ball is arranged on the right upper portion of a drain pipe port in the barrel body, and the floating ball can float up and down and block the drain pipe port when the floating ball drops down. The safety overflow device has the advantages that the safety overflow device is wholly mechanical, electrical elements are absent, and the service life is long; the structure is simple, and the maintenance is not required; the device can be serialized and standardized according to various operating modes; the condensation water tank is closed to prevent flash steams from escaping outwards; a stopping of process units caused by the fact that overflowing is prevented due to an emergency shutdown can be avoided; vacuum generation is eliminated, water pump cavitation is prevented, and investments for replacing water pumps each year are reduced; and the condensation water is convenient to recycle in a closed mode, and energy-saving technology popularization in a wide range is facilitated.
Description
Technical field
The utility model relates to a kind of water of condensation and reclaims the machine security overflow mechanism.
Background technique
Produce and life in, steam is as a kind of purposes energy very widely, discharge latent heat and part sensible heat after, be converted into liquid condensed water in high temperature, often regard waste water originally and drained, cause the waste of the energy and water resources.Enterprise begins to pay attention to energy efficiency at present, adopts Condensate recovery device that the condensed water in high temperature that produces is recycled, and under some operating mode, callable condensing water temperature is higher; Surpass 100 ℃, reclaim, can cause the effusion of flash steam, cause the waste of heat energy as adopting open type; There was enterprise to adopt enclosed to reclaim in recent years, can effectively solves the flash steam problem that leaks, but airtight, do not have the flow-off of external atmosphere for the water pot that guarantees to condense; When the condensate pump disorderly closedown, the water pot that condenses is full of very soon, and the accident free overflow mechanism causes hydrophobic can't the discharging; Influence the operation of front end with the vapour tooling, the serious parking that also can cause whole system is lost bigger.Solve this type of way at present; There is part producer to be employed in the overflow mouth of pipe and is provided with mortor operated valve or pneumatic valve; And level chain, to prescribe a time limit above last when liquid level, mortor operated valve or pneumatic valve are opened overflow mechanism automatically; But in fact since this type of automatic valve for a long time need not, tend to can't open and close at crucial moment.And the needs as requiring because of system's operation, Condensate recovery device is shut down several hours sometimes, in the meantime; Condensing water temperature reduces in jar, and flash steam liquefaction can produce negative pressure in jar; When Condensate recovery device comes into operation again, can cause pump entrance pressure to reduce, the water of condensation vaporization; Cause pump cavitation, this also is insurmountable by the mode that adds self-acting valve.
Summary of the invention
Be technical deficiency more than solving, the utility model provides a kind of both can guarantee that water of condensation was airtight, and water of condensation that simultaneously again can safety overflow when accidental shutdown reclaims the machine security overflow mechanism.
The utility model is realized through following measure:
A kind of water of condensation of the utility model reclaims the machine security overflow mechanism; Comprise cylindrical shell; Said cylindrical shell upper end is communicated with the water of condensation tank top, and the cylindrical shell lower end is provided with waste pipe, is provided with the ball float that can fluctuate and when falling, block the waste pipe mouth of pipe directly over the waste pipe mouth of pipe in the cylindrical shell.
The above-mentioned waste pipe mouth of pipe is provided with smooth arc groove, and the radian of said groove is consistent with the radian on ball float surface.
Above-mentioned waste pipe nozzle diameter is less than 3/4 of floating ball diameter.
Above-mentioned ball float is the stainless steel hollow spheres.
Above-mentioned cylindrical shell upper and lower is welded with upper ring plate and lower ring plate respectively.
The beneficial effect of the utility model is: pure machinery, and no electric elements, the life-span is long; Simple in structure, non-maintaining; Can be according to various operating mode seriations and standardization; The assurance water pot that condenses is airtight, prevents that flash steam from leaking; Avoid the accidental shutdown can't overflow, caused tooling to stop; Stop the vacuum generation, prevented pump cavitation, reduced the annual more investment of water-change pump; Enclosed reclaims to make water of condensation reclaim more easily, more advantageously promotes power-saving technology on a large scale.
Description of drawings
Fig. 1: the structural representation that is the installment state of the utility model.
Fig. 2: the cross-sectional view that is the utility model.
Among the figure: 1 water pot that condenses, 2 water of condensation imports, the outlet of 3 water of condensation, 4 machine security overflow mechanisms, 5 level meters, 41 intake pipes, 42 upper ring plates, 43 lower ring plates, 44 cylindrical shells, 45 ball floats, 46 waste pipes.
Embodiment
Like Fig. 1, shown in 2; A kind of water of condensation of the utility model reclaims the machine security overflow mechanism, and machine security overflow mechanism 4 comprises cylindrical shell 44, and cylindrical shell 44 upper ends are communicated with water pot 1 top of condensing; Cylindrical shell 44 lower ends are provided with waste pipe 46, and waste pipe 46 is as the overflow pipe of the water pot 1 that condenses.Be provided with the ball float 45 that can fluctuate and when falling, block waste pipe 46 mouths of pipe directly over waste pipe 46 mouths of pipe in the cylindrical shell 44.Water pot 1 top of condensing is water of condensation import 2, and the bottom is water of condensation outlet 3.
Concrete, waste pipe 46 mouths of pipe are provided with smooth arc groove, and the radian on the radian of groove and ball float 45 surfaces matches.Waste pipe 46 nozzle diameters are less than 3/4 of ball float 45 diameters.Ball float 45 is the stainless steel hollow spheres.Cylindrical shell 44 upper and lowers are welded with upper ring plate 42 and lower ring plate 43 respectively.
Working principle of the present invention is: when condensed water in high temperature gets into when condensing water pot 1 from water of condensation import 2, because the dilatation flash distillation, flash steam gets into cylindrical shell 44 through pipeline; Ball float 45 drops on waste pipe 46 mouths of pipe; Lower surface and atmosphere, upper surface contacts with steam, because the pressure of gravity and flash steam; Make ball float 45 block waste pipe 46, secondary vapour can't overflow thus.When the condensate pump disorderly closedown, the front end water of condensation constantly gets into the water pot 1 that condenses, and liquid level raises gradually in jar; When reaching intake pipe when suitable for reading, water of condensation flows in the cylindrical shell 44, because floating function; Ball float 45 is held up by water, and water of condensation flows out from the slit between ball float 45 and the waste pipe 46, descends up to liquid level; Ball float 45 is owing to action of gravity, again with waste pipe 46 sealings.When producing negative pressure in the jar, when atmosphere was conducted oneself with dignity greater than ball float 45 with jar buoyancy of internal pressure differences generation, ball float 45 was separated from waste pipe 46, and few part air gets into, and has destroyed the vacuum generation.
The foregoing description is said to be in order to specify this patent; Though describe through specific term in the literary composition; But can not limit the protection domain of this patent with this; The personage who is familiar with this technical field can change or revise it after the spirit of understanding this patent and principle and reach equivalent purpose, and this equivalence change and modification all should be covered by the claim scope and define in the category.
