Abstract
The utility model discloses a mixed acid washtrough, including cell body, capping, the both sides of cell body set up the wringing roller, and the bottom of cell body sets up many places bellying, the inside a plurality of submergence rollers, the high difference of submergence roller of still setting up of cell body, belted steel is by wringing roller drive along submergence roller motion, the utility model discloses the cell body is made for PPR acid -proof alkali material, adds the mixed solution of nitric acid, hydrofluoric acid and water, comes to rinse belted steel surface oxidation iron sheet through mixing the acidizing fluid concentration control in the control flume to reach the good cleaning performance in belted steel surface.
Description
Technical field
The utility model relates to chemical field, is a kind of pickling tank specifically.
Background technology
On the surface of stainless cold-rolled steel strip, because oxidation annealing process can generate oxide skin, therefore, need to remove the impurity such as belt steel surface iron scale; In production practice, the washing trough of general employing pickling hydrochloric acid solves this technical problem, common pickling tank structure is a flat cell body, steel band by one end to an other end motion, and in the process, pickling salt (sodium sulfate) solution injected in groove, battery lead plate and band steel form electrochemical circuit, thus remove the impurity such as belt steel surface iron scale.The shortcoming of this structure is: on the one hand because this pickling tank length is comparatively large, need very large space; On the other hand, cell body limited length, steel band is shorter through the time of cell body, and often effect is bad.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide the better pickling tank of a kind of pickling effect, and it is less relatively to take up room, and concrete technical scheme is:
A kind of mixing acid washing trough, comprise cell body, groove lid, the both sides of cell body arrange squeezing roller, and the bottom of cell body arranges many places lug boss, and cell body inside also arranges multiple submergence roller, and submergence roller height is different; Band steel is driven by squeezing roller and moves along submergence roller.
Described lug boss is irregular triangular pyramid type.
Described cell body is divided into two portions along steel band direction of motion, and two-part intersection arranges adjusting-flow board.
Described cell body base plate arranges turbulent blade.
The utility model has the advantages that:
Because submergence roller height is different, therefore, add the stroke of steel band in pickle solution; Be provided with many places lug boss bottom cell body, and add turbulent blade, make pickling salts solution form local and rotate, even advantageously in pickling salts solution, avoids the uneven of concentration, to carry out electrochemical reaction better; And two portions of cell body are arranged, be ensure by vigorous reaction become milder reaction afterwards gradually, improve the surface quality of steel band.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Illustrate the utility model below in conjunction with accompanying drawing, as shown in Figure 1, the utility model comprises cell body 2, groove lid 8, the both sides of cell body 2 arrange squeezing roller 1, the bottom of cell body 2 arranges many places lug boss 3, and cell body 2 inside also arranges multiple submergence roller 6, and submergence roller 6 is highly different; Band steel 7 is driven by squeezing roller 1 and moves along submergence roller 6.
Described lug boss 3 is irregular triangular pyramid type.
Described cell body 2 is divided into two portions along steel band 7 direction of motion, and two-part intersection arranges adjusting-flow board 9.
Described cell body 2 base plate arranges turbulent blade 5.
The effect of major parts of the present utility model is as follows:
Squeezing roller 1: support belt steel 7 transmission, seal cell body and extract the effect of belt steel surface liquid.
Submergence roller 6: make band steel be immersed in groove in liquid.
Lug boss 3 and turbulent blade 5: make pickling salts solution form rotary motion in cell body, be convenient to the even of concentration, improve reaction efficiency.
The utility model cell body is that PPR acid-proof base material is made, and adds the mixing solutions of nitric acid, hydrofluoric acid and water, is cleaned by mix acid liquor concentration adjustment in control flume to belt steel surface iron scale, thus reach the good cleaning performance of belt steel surface.
