Description

Technical Field

[0001] The utility model relates to the technical field of steel wire production, in particular to a pickling device for phosphating steel wire production. Background Art

[0002] Compared with ordinary steel wire, phosphated steel wire has a phosphating layer on its surface, which has better corrosion resistance. However, before phosphating, there will be a layer of oxide on the surface of phosphated steel wire, which reduces the effective penetration and reaction of the phosphating solution on the steel wire surface and affects the corrosion resistance. Therefore, a pickling device is required to pickle the steel wire.

[0003] In the prior art, a Chinese utility model application numbered 202321077844.7 discloses a stainless steel wire pickling and phosphating treatment device. After the steel wire is pickled in the pickling tank, it will enter a treatment box for water washing. The pickling liquid remaining on the surface of the steel wire will dissolve in the clean water in the treatment box, thereby increasing the acidity of the clean water. The acidic solution is still attached to the surface of the steel wire, which affects the subsequent phosphating effect of the phosphating solution on the steel wire. In addition, before pickling, dust will adhere to the surface of the steel wire, which will weaken the pickling effect, resulting in poor pickling effect and affecting the cleanliness of the steel wire surface.

DETAILED DESCRIPTION

[0049] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, in the following description, specific details such as specific system structures and technologies are proposed for the purpose of explanation rather than limitation, so as to thoroughly understand the embodiments of the utility model. However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the utility model.

[0050] The utility model provides a pickling device for phosphating steel wire production, according to the attached manual Figure 1 To Attachment Figure 5 It can be seen that a pickling device for phosphating steel wire production mainly includes the following parts or components: a processing box 10, a support plate 20, a spray pipe 30, a neutralizer box 32, and a water removal mechanism 50. The connection relationship of each part or component is as follows:

[0051] A first partition 11 vertically arranged inside the processing box 10 divides the processing box 10 into a pickling tank 12 and a cleaning tank 13 in front and back. Two first guide rollers 14 are arranged at the bottom of the pickling tank 12, and two second guide rollers 15 are arranged on the side wall of the processing box 10 above the pickling tank 12; a support plate 20 is arranged on the side wall of the processing box 10 in front of the pickling tank 12, and a plurality of feed holes 21 are arranged thereon at intervals. A cleaning mechanism 22 arranged on the support plate 20 is used to clean the steel wire in the feed hole 21; a spray pipe 30 is horizontally arranged at the processing box 10 above the cleaning tank 13 A plurality of nozzles are arranged on the side wall of the box 10, and one end of the spray pipe 30 is connected to the bottom of the cleaning tank 13 through the water inlet pipe 31; the neutralizer box 32 is connected to the cleaning tank 13 through the first liquid inlet pipe 33, and two stirring shafts 40 are arranged at the bottom of the cleaning tank 13, and one end of each stirring shaft 40 is connected to the rotating shaft of the cleaning tank 13 and penetrates through it, and is connected to the driving mechanism 41, and rotates in opposite directions under the action of the driving mechanism 41; the water removal mechanism 50 is arranged on the side wall of the processing box 10 on the rear side of the cleaning tank 13, and is used to remove clean water on the surface of the steel wire.

[0052] After the steel wire passes through the feed hole 21, the dust on the surface of the steel wire will be cleaned under the action of the cleaning mechanism 22, and then it will be immersed in the pickling liquid in the pickling tank 12 under the guidance of the first guide roller 14 and the second guide roller 15 to pickle the surface of the steel wire. After the pickling is completed, the steel wire will be washed away by the clean water sprayed from the spray pipe 30 during the subsequent movement, and the sprayed clean water will fall into the cleaning tank 13 to reduce waste.

[0053] And the neutralizer in the neutralizer box 32 will flow into the cleaning tank 13 along the first liquid inlet pipe 33, and be neutralized by the neutralizer and the pickling liquid in the clean water. The pickling liquid is usually hydrochloric acid, and the neutralizer is sodium hydroxide. The two react to produce sodium chloride and water, so that the clean water in the cleaning tank 13 is neutral, so that the clean water in the cleaning tank 13 can be recycled and flow into the spray pipe 30 again through the water inlet pipe 31 to achieve recycling, effectively reducing the waste of water resources, and the neutral clean water sprayed from the spray pipe 30 can wash away the pickling liquid on the surface of the steel wire, replace the pickling liquid on the surface of the steel wire, and prevent the pickling liquid on the surface of the steel wire from affecting the phosphating effect of the steel wire. Finally, under the action of the water removal mechanism 50, the clean water on the surface of the steel wire is removed to prevent the steel wire from rusting.

The steel wire will pass through the inside of the cleaning cylinder 221, and when the rotating assembly drives the cleaning cylinder 221 to rotate, the bristles on the inner wall of the cleaning cylinder 221 will scrub the surface of the steel wire, thereby cleaning the dust on the surface of the steel wire and preventing the dust from affecting the pickling effect of the pickling liquid on the steel wire.

[0055] In this embodiment, according to the specification Figure 2 It can be seen that the rotating assembly includes: multiple first gears 222 are respectively arranged on multiple cleaning cylinders 221; the first rack 223 is slidably arranged in the first slide 224 on the support plate 20, and meshes with the multiple first gears 222; the output end of the first motor 225 is provided with a first rotating rod 227, and the free end of the first rotating rod 227 is provided with a first sliding rod 228, and the first sliding rod 228 is slidably connected with the first guide groove 229 provided at the end of the first rack 223.

[0056] When the first motor 225 drives the first rotating rod 227 to rotate, the first slide rod 228 can drive the first rack 223 to slide back and forth in the first slideway 224, and then the multiple first gears 222 meshing with the first rack 223 will rotate alternately forward and reverse, thereby driving the cleaning cylinder 221 to rotate alternately forward and reverse, so that the bristles in the cleaning cylinder 221 clean the steel wire, and the cleaning effect is good.

[0058] When the adjusting component drives the corresponding slide 413 to slide back and forth in the corresponding second slide 412, the connecting rod 414 can drive the two slides 413 to slide in the same direction in the corresponding two slides respectively, and the second racks on the two slides 413 will drive the two gears meshing therewith to rotate in opposite directions, thereby causing the two stirring shafts 40 to rotate in opposite directions. During the rotation of the two stirring shafts 40, the pickling solution and the neutralizer will react more quickly, thereby improving the reaction efficiency, thereby causing the clean water in the cleaning tank 13 to tend to be neutral, so that the clean water can be recycled.
