Description
(1) technical field: the utility model relates to a kind of bubble elimination device, specifically is a kind of alkali lye bubble elimination device that is used on the zinc-plated unit cleaning equipment.
(2) prior art: zinc-plated unit need clean surface of steel plate residual oil stain and dust in the process to the coil of strip surface galvanizing of uncoiling, and its cleaning process comprises that mainly alkali rinse bath, electrolytic cleaning, water scrubs and water rinse etc.After steel plate enters cleaning equipment, at first enter the alkali rinse bath, and to scrub recycle pump by alkali be 75 ℃ with temperature, pressure is that the alkali lye of 2.5bar is sprayed onto the upper and lower surface of steel plate by nozzle, alkali lye is back in the alkali groove more then.Alkali lye is main cleaning medium in cleaning process, and alkali lye is easy to generate a large amount of foams and alkali steam, particularly foam can major part concentrates on alkali and scrubs in the circulation groove, if not eliminating, foam can not seriously influence the alkali lye circulation, foam is excessive especially can breakdown operation on-the-spot three changes hygienic condition, and influence normally patrolling and examining and adding alkali work of workman, and the operating personnel has only frequent water to clean, not only strengthen workman's workload, simultaneously safety in production is also caused very big hidden danger.
Present usually conduct method is to add defoamer in alkali lye, because zinc-plated unit is a continuous production equipment, and the alkali lye foam also is constantly to produce continuously, adding defoamer also needs to add at any time, the mode of this a large amount of adding defoamers not only increases the cost of product, also needs the personal management simultaneously, even like this, the excessive phenomenon of alkali foam also takes place often, causes the alkali lye waste.Also have a kind of water, gas to mix in addition and produce the type defoaming device (ZL200720185239.6) that water smoke sprays into alkali lye, but this device in use can spray into a large amount of cold water to alkali lye, the temperature of alkali lye and the liquid level of alkali groove there is bigger influence, cause the consumption of steam to increase greatly, improved production cost, defoaming effect is general.Can not satisfy needs of production under the environment such as higher or alkali lye is dirtier at the alkali pump rotating speed.
By a large amount of experiments contrast, to the foam inhibition effect of alkali lye best be high pressure water washing, secondly be that the pressurized air annular purges.But high pressure water washing is to alkali liquid temperature and property
Bigger change can be arranged, therefore inadvisable.The simple pressurized air annular purging mode that adopts is in normal life cycle of alkali lye (20～30 days), can reach requirement (foam does not overflow the notch cofferdam) fully under most situations, but use a couple of days in later stage in the cycle, the alkali lye spy is dirty fully, foam is abundant especially, the simple pressurized air annular purging that adopts just can not reach requirement fully, has a spot of foam and overflows the notch cofferdam, and therefore the mode that must adopt combination to be provided with can reach requirement.
(3) summary of the invention: the purpose of this utility model just provides a kind of alkali lye composition, liquid level and alkali liquid temperature of not changing, adopt physical method to eliminate the alkali lye foam, non-maintaining, be used for alkali lye bubble elimination device on the zinc-plated unit cleaning equipment cheaply.
The technical solution of the utility model is: upper-lower position is equipped with water and two ring nozzles of pressurized air respectively in alkali groove notch cofferdam, and wherein water spouting nozzle is contained in the compressed-air atomizer top, and two nozzles all are fixed on the tunable arrangement that can move up and down and rotate; The entrance end of described water spouting nozzle and compressed-air atomizer is connected with water pipe and compressed air line with flexible pipe respectively; Ball valve and magnetic valve are housed respectively on described water pipe and compressed air line; Magnetic valve on the compressed air line directly links to each other with lead with the Long-distance Control case, is connected with the time relay between magnetic valve on the water pipe and the Long-distance Control case.
Described tunable arrangement comprises the vertical tube of fixing two ring nozzles, and vertical tube is equipped with one section sleeve pipe outward, is equipped with respectively on the sleeve pipe to adjust bolt and fixing catch.
The utility model alkali groove notch in addition the pressurized air annular purge the water spray ring nozzle of relief relay time control, the alkali lye foam is carried out mandatory destruction, the time ratio that the time of general water spray and pressurized air annular purge is 0.5:9.5, therefore can under the situation that does not change alkali lye composition and temperature, reduce the alkali lye foam in a large number, effectively improve peripheral operating environment, and can overcome the expense of employing chemical process (as defoamer) generation and the disadvantageous effect that the alkali lye composition changes.This apparatus structure is simple, operation and maintenance cost are low.
The principle of work of this device is exactly that pressurized air sprays to the alkali lye foam at a high speed by ring nozzle, utilizes pressurized air surging force and temperature head directly to destroy the tension force of foam surface, eliminates the foamy purpose thereby reach; Use a couple of days in later stage simultaneously in view of each cycle, the alkali lye spy is dirty fully, and foam is abundant especially, adopts the pressurized air annular to purge merely and just can not reach requirement fully, has a spot of foam and overflows the notch cofferdam, is aided with the water spray this moment,
Can eliminate foam fully and reach requirement.
This device is through on probation at Baosteel Huangshi coating plate company limited galvanization production line degreasing line water jacket, the supplementary electrical device realization is long-range intermittently to be controlled with the time, alkali lye alkali point 20,70 ℃ of alkali liquid temperatures, grease-removing agent: the efficient grease-removing agent of Ji Rui JR, alkali pump rotating speed: 2500～2900 rev/mins, result on trial shows, reach fully and not only can effectively eliminate foam but also do not change alkali lye composition and temperature, non-maintaining, purpose cheaply possesses the prospect of promoting in this enterprise and enterprise of the same type.
