Description
Technical field
The utility model relates to the device in a kind of hot-rolled steel sheet or steel band acid cleaning process, particularly relates to circulating water recovery device in a kind of strip pickling process.
Background technology
The method of the oxide skin on acid solution removal steel surface and corrosion thing is utilized to be called pickling.General aqueous solution product being immersed sulfuric acid etc., to remove the films such as the oxide compound of metallic surface, is pre-treatment or the intermediate treatment of the techniques such as plating, enamel, rolling.Band steel after overpickling, enter washing bath and wash, existing installation be by washing after waste water directly drain, the waste water of draining is acid, so not only contaminate environment, and waste water resource, therefore need a kind of equipment utilized by waste water reclamation, solve the problem of environmental pollution.
Summary of the invention
The utility model needs the problem solved to be to provide circulating water recovery device in a kind of strip pickling process, and device structure advantages of simple, effectively make use of resource, reaches the object of environmental protection.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: circulating water recovery device in a kind of strip pickling process, comprise pickling tank, pinch roll, washing bath, squeezing roller, strainer, acid liquor storage tank, first power-driven pump, material-compound tank, second power-driven pump and pipe connecting, described acid liquor storage tank, first power-driven pump, material-compound tank is connected by pipe connecting successively with the second power-driven pump, the exit end of described second power-driven pump is connected with pickling tank by pipe connecting, the exit end of described washing bath is connected with the entrance end of strainer by pipe connecting, the exit end of described strainer is connected with the entrance end of material-compound tank by pipe connecting, the entrance end place of described washing bath is provided with pinch roll, washing bath exit end place is provided with squeezing roller.
Further, gac is provided with in described strainer.
Further, described material-compound tank is erosion resistance material.
Further, the gap of described pinch roll and squeezing roller is adjustable.
Further, described first power-driven pump and the second power-driven pump are erosion resistance materials.
The advantage that the utility model has and positively effect are: this device structure advantages of simple, efficiently utilizes the waste water after washing, economize on resources, and reaches the object of protection of the environment.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure:
1-is with steel, 2-pickling tank, 3-pinch roll, 4-washing bath, 5-squeezing roller, 6-strainer, 7-acid liquor storage tank, 8-first power-driven pump, 9-material-compound tank, 10-second power-driven pump, 11-pipe connecting.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, the utility model provides circulating water recovery device in a kind of strip pickling process, comprise pickling tank 2, pinch roll 3, washing bath 4, squeezing roller 5, strainer 6, acid liquor storage tank 7, first power-driven pump 8, material-compound tank 9, second power-driven pump 10 and pipe connecting 11, described acid liquor storage tank 7, first power-driven pump 8, material-compound tank 9 is connected by pipe connecting 11 successively with the second power-driven pump 10, the exit end of described second power-driven pump 10 is connected with pickling tank 2 by pipe connecting 11, the exit end of described washing bath 4 is connected with the entrance end of strainer 6 by pipe connecting 11, the exit end of described strainer 6 is connected with the entrance end of material-compound tank 9 by pipe connecting 11, the entrance end place of described washing bath 4 is provided with pinch roll 3, the exit end place of washing bath 4 is provided with squeezing roller 5.
Be provided with gac in described strainer 6, waste water is first carried out contaminant filter.
Described material-compound tank 9 is erosion resistance materials.
The gap of described pinch roll 3 and squeezing roller 5 can regulate according to the thickness of band steel.
Further, described first power-driven pump 8 and the second power-driven pump 10 are erosion resistance materials.
The working process of this example: band steel 1 enters in pickling tank 2, steel is with to enter washing bath 4 after pickling, first washing bath 4 is entered by pinch roll 3 before band steel enters washing bath 4, then through squeezing roller 5, the moisture on band steel 1 is extracted, waste water in washing bath 4 enters in strainer 6 through the exit end of washing bath 4 and filters, then enter in material-compound tank 9, waste water through filtering is acid, but concentration does not reach the standard of pickle solution, therefore the acid solution extracted from acid liquor storage tank 7 in a certain amount of acid solution and material-compound tank proportioning can be carried out, reach the concentration of pickle solution, the pickle solution configured can be entered in pickling tank 2 by the second power-driven pump 10.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
