Technical Field

[0001] The utility model relates to the technical field of pickling devices, and specifically relates to a spring wire pickling device with adjustable acidity and alkalinity. Background Technique

[0002] At present, during the heat treatment process of steel wires, due to contact with oxygen at high temperatures, a layer of scale will form on their surfaces. Before the next plating (coating) process, this layer of scale must be removed, otherwise a firm plating (coating) layer cannot be obtained. The main method of removing scale is to let the steel wire pass through a hydrochloric acid or sulfuric acid tank, so that the scale on the surface of the steel wire reacts chemically with the acid solution to achieve the purpose of removing the scale.

[0003] According to a high-performance spring wire pickling and phosphating device with self-adjustable acidity and alkalinity disclosed in the Chinese utility model publication No. CN215757615U, which includes a phosphating tank, and further includes: an input pipe, the input pipe is arranged above the phosphating tank, the top of the phosphating tank is fixedly connected with a first support rod, the top of the first support rod is fixedly connected with the outer surface of the input pipe, a first drainage pipe is communicated with the outer surface of the input pipe near one end thereof, and a second drainage pipe is communicated with the outer surface of the input pipe near the first drainage pipe; a second support rod, the second support rod is fixedly connected to the top of the phosphating tank, the top of the second support rod is fixedly connected with a connecting pipe, and an adjusting device, the adjusting device is arranged at the end of the connecting pipe, the adjusting device includes a first gear, the end of the first gear is rotatably connected with the end of the connecting pipe, and a through hole is opened at the top of the first gear, which is convenient for adjusting the acidity and alkalinity of the phosphating tank.

Therefore, the uniformity after mixing of the acid-base solution is reduced, which is not convenient for enhancing the pickling effect of the spring wire. Content of the Utility Model

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The discharging mechanism 27 includes: a second motor 271, symmetrically arranged on the top of the cylinder body 22; a lead screw 272, fixedly connected to the output shaft of the second motor 271; a threaded block 273, threadedly connected to the lead screw 272; a connecting rod 274, fixedly connected to the back end of the threaded block 273, and the other end of the connecting rod 274 extends into the cylinder body 22; a piston disc 275, fixedly connected to one end of the connecting rod 274 located inside the cylinder body 22 and slidably connected to the inner side wall of the cylinder body 22; a first solenoid valve 276, arranged at the outlet of the liquid storage barrel 26; a second solenoid valve 277, arranged inside the cylinder body 22, and the first solenoid valve 276, the second motor 271 and the second solenoid valve 277 are all electrically connected to the controller 14. A liquid level sensor 6 is arranged on the first solenoid valve 276.

[0048] During use, the staff pour acidic and alkaline solutions into the two liquid storage barrels 26 respectively, pour pickling solution into the reaction tank 11, place the spring steel wire inside the reaction tank 11 for reaction, and the pH detector 13 detects the pH value in the reaction tank 11 in real time. When the pH value is abnormal, the pH detector 13 transmits the value to the controller 14, and the controller 14 controls the adjustment component 2 to adjust the pH value accordingly: the controller 14 controls the discharging mechanism 27 to discharge a certain amount of acidic or alkaline solution into the liquid collecting cylinder 21: the piston disk 275 of the discharging mechanism 27 stays in the area closest to the liquid collecting cylinder 21 inside the cylinder body 22 in the initial state, the second electromagnetic valve 277 is in a closed state, the controller 14 starts the second motor 271 and opens the first electromagnetic valve 276, the threaded block 273 threadedly connected to the lead screw 272 moves away from the liquid collecting cylinder 21, the threaded block 273 drives the connecting rod 274 to make the piston disk 275 away from the liquid collecting cylinder 21, a negative pressure state is formed inside the cylinder body 22, and the solution stored in the liquid storage barrel 26 is sucked into the cylinder body 22 by negative pressure. The controller 14 controls the running time of the second motor 271. After the second motor 271 is turned off, a certain amount of solution is pumped into the cylinder body 22. At this time, the controller 14 closes the first electromagnetic valve 276, opens the second electromagnetic valve 277, and drives the second motor 271 to reverse, so that the piston disk 275 pushes all the solution pumped into the cylinder body 22 into the liquid collecting cylinder 21. At this time, the controller 14 turns on the power supply of the first motor 251, the first motor 251 drives the second gear 25 to rotate, and the first gear 24 meshing with the second gear 25 drives the spray head 23 to rotate. When the spray head 23 rotates, the solution is affected by centrifugal force and gravity and splashes out through the through holes at the bottom and side of the spray head 23, increasing the spraying area and facilitating the full reaction of the added solution with the pickling solution inside the reaction tank 11. The liquid level sensor 6 monitors the solution stored in the liquid storage barrel 26, and reminds the staff to add it when the solution is less, so as to avoid affecting the next pH adjustment process.

[0049] Embodiment 2

[0050] On the basis of Embodiment 1, auxiliary functions are added.

[0051] Refer to Figures 1-5 As shown in the figure, an electric push rod 3 is arranged at the top of the liquid collecting cylinder 21. The output shaft of the electric push rod 3 penetrates and extends into the liquid collecting cylinder 21. A push plate 31 is fixedly connected to the output shaft of the electric push rod 3. The push plate 31 is slidably connected to the inner wall of the liquid collecting cylinder 21. A slider 5 is fixedly connected to the bottom of the threaded block 273. A chute 51 is opened at the top of the cylinder body 22. The slider 5 is slidably connected to the chute 51. A baffle 4 is fixedly connected to the outer side wall of the spray head 23. The baffle 4 is located below the first gear 24.

[0052] When the motor 1 controls the spray head 23 to rotate for spraying, the electric push rod 3 is started. The electric push rod 3 controls the push plate 31 to move downward. The push plate 31 scrapes the residual acidic or alkaline solution on the inner wall of the liquid collecting cylinder 21 downward and discharges it in time through the rotating spray head 23 below, avoiding the solution remaining on the inner wall of the liquid collecting cylinder 21 and affecting the accuracy of the next pH adjustment. When the threaded block 273 moves, the slider 5 slides in the chute 51. The slider 5 and the chute 51 increase the stability of the threaded block 273 during movement, thus facilitating the suction of the piston disc 275. When the spray head 23 rotates, the baffle 4 shields the bottom of the first gear 24 to prevent the splashing solution from contacting the first gear 24, which affects the service life of the first gear 24 and the accuracy of the pH adjustment.

[0053] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
