One end connects, the external acid mist tower of the other end of air draft pipe.
In such scheme, the number of row's bubble mouth is more than 2, and these row's bubble mouths are located at the same level of demoulding Chi Cebi
On height.
In such scheme, row's bubble mouth is equal with the liquid level in demoulding pond, i.e., the liquid level in demoulding pond is located at the upper of row's bubble mouth
Between end face and lower surface.
In such scheme, row steeps and be located at the 1/3 of mouth under the liquid level in demoulding pond, and row steeps and exceed at the 2/3 of mouth demoulding
On liquid level in pond.
In such scheme, the bubble elimination device body still further comprises water level controller, and the water level controller sets
Put in demoulding pond, for controlling the liquid level in demoulding pond.
In such scheme, trap is N shape pipes.
In such scheme, the bottom of trap is provided with drain valve.
Compared with prior art, this utility model feature specific as follows：
1st, be prevented from the stifled product of foam in demoulding pond so that the alkali liquor in demoulding pond can Efficient Cycle so that
Alkali liquor can preferably react with photoresist, the unnet problem of effectively solving demoulding, improve product quality；
2nd, foam is gathered in trap by pipeline, and is discharged by trap or reclaimed, and effectively solving foam is excessive
Problem, be conducive to the improvement of working environment；
3rd, by the alkali liquor in recovery trap so that alkali liquor can be reused, production cost is reduced；
4th, with simple structure and it is practical the characteristics of.
Description of the drawings
Fig. 1 is a kind of unnet bubble elimination device of LCD demouldings.
Label in figure：1st, demoulding pond；2nd, row's bubble mouth；3rd, bubble pipeline is taken out；4th, trap；5th, air draft pipe；6th, drain valve.
Specific embodiment
The unnet bubble elimination device of a kind of LCD demouldings, as shown in figure 1, the bubble elimination device body is by arranging bubble mouth 2, take out
Bubble pipeline 3, trap 4, air draft pipe 5 and water level controller composition.
Row's bubble mouth 2 is opened on the side wall in existing demoulding pond 1.The speed that the number of row's bubble mouth 2 is produced according to foam with it is many
It is few to determine.When foam produces fast speed and/or many quantity, the number for being arranged on row's bubble mouth 2 in demoulding pond 1 is more；Conversely, row
The number of bubble mouth 2 should be reduced accordingly.In this utility model preferred embodiment, the number for being arranged on row's bubble mouth 2 in demoulding pond 1 is
More than 2.In order to produce unified row's bubble effect, all row's bubble mouths 2 should be located at the same level height of the side wall of demoulding pond 1
On.By the height for controlling the liquid level in demoulding pond 1, it is ensured that row's bubble mouth 2 is equal with the liquid level in demoulding pond 1, i.e., in demoulding pond 1
Liquid level be located at row bubble mouth 2 upper surface and lower surface between.The upper surface of the too high even above row bubble mouth 2 of water level, wind flows through
It is little, it is impossible to extract foam；The lower surface of the too low even below row bubble mouth 2 of water level, extracts less than the foam on the water surface.In this practicality
In new preferred embodiment, row steeps and be located at the 1/3 of mouth 2 under the liquid level in demoulding pond 1, and row steeps and exceed at the 2/3 of mouth 2 demoulding
On liquid level in pond 1, that is, guarantee that liquid level is maintained at the position of row's bubble mouth 21/3.Liquid level in demoulding pond 1 can be by artificial
Control mode, it is also possible to realize automatically controlling for liquid level by arranging water level controller in demoulding pond 1.
The one end for taking out bubble pipeline 3 connects with row's bubble mouth 2, and the other end for taking out bubble pipeline 3 is connected with one end of trap 4.Deposit
The other end of water curved 4 is connected with one end of air draft pipe 5, the external acid mist tower of the other end of air draft pipe 5.Trap 4 is arranged on
Take out between bubble pipeline 3 and air draft pipe 5, its effect is aggregation foam, and foam is condensed wherein.Trap 4 is from existing
There is the conventional structure of sanitary apparatus, it can be U-tube, N shapes pipe or S-shaped pipe.In this utility model preferred embodiment, water
Curved 4 is N shape pipes.In order to ensure that condensing in the alkali liquor in trap 4 can be discharged, and in the bottom of trap 4 row is provided with
Water valve 6.Acid mist tower be the original equipment of factory, for eliminating etching work procedure in discharge acid gas.
A kind of unnet the removal of foam method of LCD demouldings that above-mentioned bubble elimination device is realized is：Acid mist tower is strong when working
Big distinguished and admirable foam on liquid level and float on the demoulding dirt of liquid level and take away, foam has rupture in uphill process, together
When 50 degree of high temperature the alkaline gas that go out of spent liquor evaporation be extracted rise during can partial coagulation into liquid.This this foam
The alkali liquor and alkali steam condensation liquid that rupture wash rice goes out understands reflow process in trap 4, and the alkali liquor discharged by drain valve 6 was passed through
Can also use again after filter.Thus, foam is mended removing, the use of defoamer in production process is reduced, reduce expense and pollution.
