Description

Device for avoiding carbonization of surface of wringing roller and pickling post-treatment device

Technical Field

The utility model relates to the technical field of metal pickling, in particular to a device for avoiding carbonization of the surface of a wringing roller and a pickling post-treatment device.

Background

The strip steel after normal acid washing needs to be washed by rinsing water to wash the acid liquor remained on the surface of the strip steel, and a wringing roller is arranged in the rinsing tank to separate the wringing effect, so that the rinsing water in each level of rinsing tank contains Cl ^- The steps are reduced, and the influence on the subsequent process is reduced. In order to avoid the rust defect of the strip steel caused by the water contained on the surface of the strip steel which is discharged out of the rinsing tank, a dryer device is arranged at the outlet of the rinsing tank, and the surface of the strip steel is dried. In order to effectively dry the surface of the strip steel and eliminate water marks on the surface of the strip steel, the temperature of the dryer is controlled to be more than 110 ℃.

However, because the defect of scratch is avoided in the shaking process of the strip steel, the dryer is not effectively separated from the rinsing tank and the wringing roller at the rearmost end of the rinsing tank, so that hot air of the dryer is directly blown to the wringing roller at the rearmost end of the tail of the rinsing tank (closest to the dryer) besides acting on the surface of the strip steel. Because the surface of the wringing roller is made of rubber, the roller surface is baked at high temperature of the dryer, so that the temperature of the roller surface of the wringing roller is high, and the rubber on the roller surface is carbonized. In the production process, carbonized foreign matters adhere to the surface of the strip steel, so that the defect of pressing the foreign matters can be generated, and the quality of the product is affected. In this case, if a strip steel with high surface demand is to be produced, the wringing roller needs to be replaced, which affects the production operation.

Fig. 1 is a schematic structural view of an apparatus 100 for preventing carbonization of a surface of a wringing roller 200 according to an embodiment of the present utility model, wherein the surface of the wringing roller 200 is rubber and is located in a hot air range of a dryer, and as shown in fig. 1, the apparatus 100 includes: a mounting portion 10, the mounting portion 10 having an elongated structure; a plurality of nozzles 20 provided on the mounting portion 10, the plurality of nozzles 20 being arranged at intervals along the extending direction of the mounting portion 10 and being used to spray compressed air or water mist toward the wringer roller 200.

According to the technical scheme, compressed air or water mist can be sprayed towards the wringing roller 200 to cool the surface of the wringing roller 200, so that rubber on the surface of the wringing roller 200 is prevented from being carbonized under the action of high temperature, the quality of strip steel is prevented from being influenced by carbide, and the wringing roller does not need to be replaced frequently. In the embodiment of the present utility model, the installation part 10 has a long structure, and the plurality of nozzles 20 are arranged at intervals along the extending direction of the installation part 10, so that the extending direction of the installation part 10 is identical to the length direction of the wringer roller 200 when in use, which is beneficial to spraying compressed air or water mist along the length direction of the wringer roller 200 completely so as to sufficiently cool the surface of the wringer roller 200.

In some embodiments of the present utility model, the nozzles 20 may spray water in mist form and the nozzles 20 may spray water toward the wringing roller 200, and the number of the nozzles may be adjusted according to the spray angle and the width of the strip steel, but it is required that the entire length direction of the wringing roller 200 is completely covered by the water mist. The plurality of nozzles 20 may be uniformly disposed, and the distances between adjacent two of the nozzles 20 are the same. Reasonable water mist spraying quantity can be set so as to reduce or avoid water mist from being directly sprayed on the strip steel.

In some embodiments, a plurality of nozzles 20 are used to spray the water mist, and the mount 10 is located at the inlet side of the wringer roller 200. In operation, the strip enters between a pair of wringer rollers 200 from the inlet side and exits the wringer rollers 200 from the outlet side. By providing the mounting portion 10 at the inlet side of the wringer roller 200, it is possible to reduce or prevent water mist from leaving the wringer roller 200 with the strip steel, affecting the subsequent drying effect. The nozzle 20 sprays water mist from the inlet side of the wringing roller 200, even if part of the water mist is sprayed on the strip steel, little water mist leaves the wringing roller 200 along with the strip steel and enters the dryer after the wringing action of the wringing roller 200, and the effect of drying the surface of the strip steel is hardly affected.

In some embodiments, the water mist sprayed from the nozzle 20 has a particle size of 1 to 3 μm. The particle size range can ensure that the water mist is uniformly and rapidly dispersed on the surface of the wringing roller to cool.

In some embodiments, a difference between a distance L1 between two nozzles 20 located at the outermost side in the extending direction of the mounting portion 10 and a length L2 of the wringer roller 200 is less than a predetermined value. That is, the distance L1 between the two nozzles 20 at the outermost side and the length L2 of the wringing roller 200 may be the same or relatively close, so that the two nozzles 20 at the outermost side may respectively perform air-jet or water-jet mist cooling on two ends of the wringing roller 200, and the plurality of nozzles 20 in the middle may perform air-jet or water-jet mist cooling on the middle portion of the wringing roller 200, thereby enabling the compressed air or water-jet to cover the surface of the wringing roller 200 along the length direction of the wringing roller 200, realizing a comprehensive and uniform cooling effect, and avoiding carbonization due to insufficient local cooling.

In some embodiments, the number of mounting portions 10 is two, both mounting portions 10 are provided with a plurality of nozzles 20 (for example, 6 nozzles 20 may be provided on each mounting portion 10) and both mounting portions 10 are disposed side by side. The wringing roller 200 is usually in the form of a pair of rollers, and includes two wringing rollers arranged side by side up and down, and the two wringing rollers can be respectively sprayed with air or water mist to cool by using the nozzles 20 on the two mounting portions 10.

In some embodiments, the radial dimension of the mounting portion 10 is 4-7 cm, for example 5cm. The appropriate size may be selected according to the actual situation.

The utility model also provides an acid washing post-treatment device, which comprises: a rinse tank; a dryer installed at an outlet of the rinsing tank; the squeezing roller 200 is arranged at the tail part of the rinsing tank and positioned in the hot air range of the dryer, and the surface of the squeezing roller 200 is rubber; and the apparatus 100 for preventing carbonization of a wringer roller surface according to any of the above embodiments, wherein the extension direction of the mounting portion 10 is the same as the length direction of the wringer roller 200.

In some embodiments, the mounting portion 10 is mounted to the rinse tank, such as by brackets.
