Abstract
A drying roll cooling device for a cleaning stage of galvanized steel strips belongs to the technical field of cold-rolled sheet galvanizing equipment and is used for protecting drying rolls and improving cleaning effects of products. The technical scheme includes that the drying roll cooling device consists of a group of desalted water spray beams, the desalted water spray beams are hollow long pipes mounted on upper and lower surfaces of a steel strip in front of the drying rolls, the axis of each spray beam is perpendicular to the advancing direction of the steel strip, the spray beam is provided with a plurality of spray nozzles which form included angles ranging from 30 degrees to 60 degrees with the surfaces of the steel strip, and one end of each spray beam is closed while the other end is communicated with a desalted water container via a pipeline. Desalted water sprayed from the spray nozzle can prevent high-temperature rising water contacting with the drying rolls completely and indirectly reduce working temperature of the drying rolls, so that the temperature of the rising water can be increased and cleaning effect can be improved obviously. Further, ageing speed of rubber surfaces can be reduced along with reduction of surface temperature of the drying rolls, thereby prolonging service life of the drying rolls, prolonging maintenance cycle of the cleaning stage to sixty days from seven days, and reducing replacement cost greatly.
Description
Technical field
The utility model relates to a kind of squeezing roller refrigerative device to Galvanized Steel Strip cleaning section rinse tank, belongs to cold rolled sheet galvanizing equipment technical field.
Background technology
In the production technique of zinc-plated cold rolled sheet, cleaning is unusual the key link, and the quality of Galvanized Steel Strip is played crucial effects.The general employing of cold rolled sheet factory galvanizing line cleaning section is horizontal, and chemistry and physics clean the mode that combines.Rinse tank is as last procedure of cleaning section, and the effect of playing is vital.Have alkali lye to scrub groove in rinse tank, be arranged in order two rows squeezing roller, support roll and brush roll in the groove, steel band passes from the two rows roller.
Main defective through the product after the cleaning section is that stain is pressed at present, and the production board face has been covered with the point-like stain, and size shape and density have nothing in common with each other, and all are judged to be unacceptable product.Through technology and device analysis, it is to cause in rinse tank that stain is pressed into defective, but the origin cause of formation is divided into two kinds again: (one) rinse water temperature low (＜60 ℃), and the gathering of rinse water inner suspension greasy filth is grown up, after the squeezing roller extruding, there is a small amount of greasy filth to residue on the steel plate, causes black spot defect; (2) heighten rinse water temperature (＞80 ℃), high water temperature reduces rinse water inner suspension greasy filth particle diameter greatly, but high-temperature water quickens the aging of squeezing roller glue face, makes squeezing roller softening, make that small volume suspension oil mud is expressed on the steel band by the aged squeezing roller in the rinse water, cause black spot defect.
Because the not wired outer circulation case of rinse tank, the online self-circulation of rinse water, this suspension greasy filth president's phase in the rinse water of just causing exists, water temperature, aging three aspects of suspension greasy filth and squeezing roller glue face influence each other, and along with the increase of steel transportation amount, the balance of three aspects will be broken, stain occurs and be pressed into defective, and be irreversible.Production line is forced to overhaul, and changes rinse water and replacing squeezing roller in the rinse tank.Cleaning section becomes the bottleneck of cycled recondition, has seriously restricted the continuity of producing.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of mode by the protection squeezing roller and makes that heightening the rinse water temperature becomes possibility; and then the stain that causes of the greasy filth particle that reduces to suspend, to improve the Galvanized Steel Strip cleaning section squeezing roller refrigerating unit of product cleaning performance.
The technical scheme that solves the problems of the technologies described above is:
A kind of Galvanized Steel Strip cleaning section squeezing roller refrigerating unit, it is made up of one group of de-salted water spray beam, the spray beam is the long tube of hollow, be installed in the steel band upper and lower surface of squeezing roller front, the axis of spray beam is vertical with the steel band working direction, on the spray beam a plurality of nozzles is arranged, and nozzle becomes 30--60 ° of angle with steel strip surface, the sealing of spray beam one end, the other end is connected by pipeline with the de-salted water container.
Above-mentioned Galvanized Steel Strip cleaning section squeezing roller refrigerating unit has pressure pump and flow control valve in the connecting pipeline of described de-salted water container and spray beam.
Adopt the Galvanized Steel Strip cleaning section squeezing roller refrigerating unit of this structure, on the one hand, the de-salted water of the nozzle ejection on the spray beam can be blocked high-temperature rinsing water fully and contact with squeezing roller, reduced the working temperature of squeezing roller indirectly, because high-temperature rinsing water lowers greatly to the influence of squeezing roller, therefore can improve the rinse water temperature, it is controlled between 80-90 ℃, cleaning performance significantly improves; On the other hand, some room temperature de-salted water directly contacts with squeezing roller, reduces its surface temperature, and glue face aging speed is reduced, and in the work-ing life of having improved squeezing roller, the cleaning section turnaround was increased to 60 days by seven days, and replacement cost reduces greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an installation site of the present utility model synoptic diagram.
Mark is as follows among the figure: spray beam 1, nozzle 2, flange 3, steel band 4, squeezing roller 5.
Embodiment
Show among the figure, the utility model is one group of spray beam 1 that is installed in the preceding steel band upper and lower surface of squeezing roller, spray beam 1 is the long tube of hollow, the axis of spray beam 1 is vertical with the steel band working direction, the one end sealing of the long tube of spray beam 1, the other end has flange 3 to be connected with hydraulic pipe-line, and hydraulic pipe-line connects the de-salted water container.
Show on the long tube of spray beam 1 a plurality of nozzles 2 are arranged among the figure, nozzle 2 becomes 30--60 degree angle with steel band 4 surfaces, and the nozzle 2 that the embodiment among the figure shows is 3.The de-salted water of nozzle 2 ejections can be blocked contacting of high-temperature rinsing water and squeezing roller 5 fully, has realized the cooling protection to squeezing roller 5, therefore can improve the temperature of high-temperature rinsing water, makes cleaning performance significantly improve.
In order to guarantee the water spray effect of nozzle 2, in the connecting pipeline of de-salted water container and spray beam 1, pressure pump and flow control valve are arranged.Will guarantee that in the water spray process hydraulic pressure reaches 6 kilograms, flow can manually be regulated by regulated valve.
The room temperature de-salted water of squeezing roller refrigerating unit ejection of the present utility model has played cooling effect to squeezing roller, greatly reduces the squeezing roller high temperature ageing, has improved the work-ing life of extracting effect and having prolonged squeezing roller.Simultaneously the rinse tank water temperature can improve 10 ℃, reaches in water temperature under 90 ℃ the situation steel band is carried out rinsing, and wash effect significantly increases.
