Accompanying drawing explanation
Below with reference to figure, the utility model is described in further detail.The accompanying drawing forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the sectional view of the utility model preferred embodiment; And
Fig. 2 is the schematic diagram of the utility model preferred embodiment.
Embodiment
Refer to Fig. 1 and Fig. 2, preferred embodiment of the present utility model provides one closely low lift water plug, comprises water output magazine 1, object groove 4, overflow downcomer 2, U-tube road 6 and compressed air line 9.
Wherein, one end of overflow downcomer 2 is provided with flow-off 3, and this flow-off 3 is communicated with water output magazine 1; 6 liang, this U-tube road end is communicated with overflow downcomer 2 and object groove 4 respectively; This compressed air line 9 one end is connected on this U-tube road 6, utilize pressurized air will be evacuated in object groove 4 from water output magazine 1 overflow to the water in overflow downcomer 2, water output magazine 1 upgrades water in groove by constantly adding fresh water, ensures the turbidity test of the water in groove; The water constantly added into makes the water level in this groove raise, and higher than flow-off 3, the water on liquid level surface is flowed into overflow downcomer 2 from flow-off 3
Again, be connected bottom described overflow downcomer 2 with U-tube road 6, described U-tube road 6 is in opening up U-shaped, U-tube road 6 is first arranged downwards, then U-tube road 6 is arranged on the limit of object groove 4, then changes direction stringing vertically upward, whole pipeline formed one large, opening up U-shaped.
Described be communicated with to connect apart from 15 to 20cm place bottom U-tube road 6 with compressed air line 9 establish, the selection of U-tube road 6 caliber size to be drawn water flow and determining according to design, makes average current velocity in U-tube road 6 lower than 3dm/s; When other conditions are constant, U-tube road 6 bore is larger, and average current velocity is less, is more conducive to raising and draws water efficiency.
Be provided with the intercommunicating pore 7 that diameter is 1mm between this compressed air line 9 and U-tube road 6, the air pressure of described compressed air line 9 is 0.01 to 0.02MPa, and described compressed air line 9 is provided with the valve 8 regulating and enter the pressurized air tolerance on U-tube road 6.
Moreover described flow-off 3 is 10cm with the height difference of object groove 4, wherein, arranges an air discharge mouth 12 when described U-tube road 6 extends to the ullage of object groove 4.U-tube road 6 extends upwardly to and is bent downwardly than after high about the 15 ~ 20cm of the cell body liquid level of object groove 4, is then connected to downwards in object groove 4, flows into downwards voluntarily in object groove 4 after allowing the water in the U-tube road 6 upwards arranged be promoted to pipeline peak.
The one that this preferred embodiment provides is low lift water plug closely, and its specific implementation process is as follows:
After water overflow enters overflow downcomer 2, cause the other of U-tube road 6 by U-tube road 6, liquid level is identical with flow-off 3 liquid level; Now blast air from U-tube road 6 close to bottom (water outlet side), bubble in U-tube road 6 rises and produces slight thrust upwards to the water above bubble, it is the most violent to the stirring of the water in U-tube road 6 when bubble breaks after also rising to liquid level to water the generation vigorous stirring, particularly bubble in U-tube road 6 simultaneously; Water is up pushed away by bubble, exceeds original liquid level; Bubble vigorous stirring causes spray of water simultaneously, splashes or will be flow to downwards in object groove 4 along pipeline by the water that bubble raises.
With reference to figure 2, impact is drawn water the factor of speed and efficiency: the factor such as height difference c, compressed-air actuated tolerance of bore d, the lifting height a on U-tube road 6, the intercommunicating pore 7 of compressed air line 9 and flow-off 3.The bore d on U-tube road 6 increases, and is conducive to raising and draws water speed and to draw water efficiency; Lifting height a reduces, and is conducive to the lifting of the speed of drawing water and the increase of efficiency of drawing water; The intercommunicating pore 7 of compressed air line 9 increases with the height difference c bottom U-tube road 6, is conducive to draw water speed and raising of lifting and draws water efficiency, while also can increase the lift of water plug; Compressed-air actuated tolerance increases, and the lift of speed of drawing water and water plug increases, but efficiency of drawing water can decline.
The water flow in overflow downcomer 2 can be extracted in object groove 4 by this water extraction way, if overflow downcomer 2 does not have water overflow to come in, so the water level of U-tube road 6 feed-water end will reduce, and the value of lifting height a is increased, and the value of the height difference b of compressed air communication hole and flow-off liquid level diminishes simultaneously; B value diminishes and will change the maximum pumping lift of this water plug, makes it to diminish; When a value is more than or equal to the lift of water plug, water plug will no longer draw water in object groove 4.
Under different condition parameter, the result of drawing water of this water plug is as follows:
When d, tolerance, c, b fix, the speed of drawing water of different lifting height a value correspondence is as shown in table 1-1:
Table 1-1
When d, tolerance, c, a fix, the speed of drawing water of different b value correspondence is as shown in table 1-2:
Table 1-2
When d, a, b, c fix, what different tolerance was corresponding draws water speed as shown in table 1-3:
Table 1-3
For the demand of drawing water of short distance low lift, use this water plug to draw water, only need the pressurized air arranged pipeline and low pressure is provided, just can complete the object of drawing water; By this water plug being applied to the transference of some sparge waters in paint line and recycling, transfer and the recycling of water can be completed under the condition of low construction input cost and low operating cost, reach water saving and save the object of the energy.
As can be seen from the above description, the utility model the above embodiments achieve following technique effect:
The utility model provides a kind of water plug of closely low lift, be applicable to the transfer recycling of sparge water between paint line different slots and the liquid orientation transfer of short distance low lift, performance safety is reliable, implementation cost is cheap, operating cost is low, there will not be vaccuum phenomenon, be easy to control.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model; For a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
