Description
Technical field
The utility model relates to the reverse turbulent flow flushing arrangement of a kind of hot-rolled steel sheet or steel band pickler, particularly a kind of acid cleaning process, is applicable to structural carbon steel hot rolled strip pickling lines.
Background technology
The raw material of carbon steel cold rolled sheet is hot rolled strip, there is the iron scale that a layer thickness is 6 ~ 15 μm in carbon steel hot rolled strip surface, this layer of iron scale generates under the high temperature after hot continuous rolling, iron scale is the oxide compound of iron, form primarily of FeO, Fe2O3, Fe3O4, the iron scale on strip surface must be cleaned up before cold rolling, guarantee is produced and quality product smoothly.
What present strip pickling production line was conventional is roller technique, and acid tank respectively has a stone roll in end, has forward and backward cover, above forward and backward cover, respectively install exhaust equipment above stone roll; Acid tank section principal piece, between the cover of front and back, employing is added a cover, and U-shaped tank is inserted on lid limit, escapes with water seal acid-mist; As band steel passage, import and export are open, or hang the many soft curtains of moulding of formula and stop, are to rely on the negative pressure formed into and out of the pressure difference of holding the flow of vacuum fan exhausting at this region and air, processed further on acid mist suction absorption tower, acid mist is not leaked.This kind of device structure size is large, and the acid solution amount that pickling tank needs is large, and during heating, energy consumption is high, and pickling speed is slow, wayward, weak effect, the poor product quality of production.
Summary of the invention
The utility model needs the problem solved to be to provide the reverse turbulent flow flushing arrangement of acid cleaning process, device structure advantages of simple, save energy consumption, the good product quality of process.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the reverse turbulent flow flushing arrangement of acid cleaning process, comprise pinch roll, pickling tank, squeezing roller, acid solution inlet pipe, interchanger, power-driven pump, pipe connecting, strainer, hold-up vessel and acid solution outlet pipe, described hold-up vessel, strainer, power-driven pump is connected by pipe connecting successively with interchanger, the exit end of described interchanger is connected with one end of pickling tank by acid solution inlet pipe, the other end of described pickling tank is connected with the inlet end of described hold-up vessel by acid solution outlet pipe, in described pickling tank, acid solution outlet pipe place is provided with pinch roll, in described pickling tank, acid solution inlet pipes is provided with squeezing roller.
Further, described power-driven pump has acid resistance.
Further, described hold-up vessel is erosion resistance material.
Further, the gap of described pinch roll and squeezing roller is adjustable.
The advantage that the utility model has and positively effect are: this device structure advantages of simple, and cleaning speed is improved, and production efficiency is high, the good product quality of process, and pickle solution recoverable, reduces energy-output ratio.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure:
1-is with steel, 2-pinch roll, 3-pickling tank, 4-squeezing roller, 5-acid solution inlet pipe, 6-interchanger, 7-power-driven pump, 8-pipe connecting, 9-strainer, 10-hold-up vessel, 11-acid solution outlet pipe.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, the utility model provides the reverse turbulent flow flushing arrangement of acid cleaning process, comprise pinch roll 2, pickling tank 3, squeezing roller 4, acid solution inlet pipe 5, interchanger 6, power-driven pump 7, pipe connecting 8, strainer 9, hold-up vessel 10 and acid solution outlet pipe 11, described hold-up vessel 10, strainer 9, power-driven pump 7 is connected by pipe connecting 8 successively with interchanger 6, described power-driven pump 7 has acid resistance, described hold-up vessel 10 is erosion resistance materials, the exit end of described interchanger 6 is connected with one end of pickling tank 3 by acid solution inlet pipe 5, the other end of described pickling tank 3 is connected with the inlet end of described hold-up vessel 10 by acid solution outlet pipe 5, in described pickling tank 3, acid solution outlet pipe 11 place is provided with pinch roll 2, in described pickling tank 3, acid solution inlet pipe 5 place is provided with squeezing roller 4, the gap of described pinch roll 2 and squeezing roller 4 is adjustable.
The working process of this example: band steel 1 one end enters in pickling tank 3 by pinch roll 2, then pickling tank 3 is gone out by squeezing roller 4, acid solution is stored in storage tank 10, power-driven pump 7 extracts the acid solution in storage tank 10, acid solution is first filtered by strainer 9, then power-driven pump 7 is entered, liquid is squeezed in interchanger 6 by power-driven pump 7, after being disposed in interchanger 6, pickling tank 3 is entered by acid solution inlet pipe 5, the flow direction of acid solution is contrary with the traffic direction of band steel 1, acid solution at the flows by action of fluid impingement force to acid solution outlet pipe 11, then flow in storage tank 10, wait recycles.
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.
