A plurality of wire guides 3 are also provided inside the washing tub 2.
The number of the cleaning tanks 2 is 1 or 2, the length and the width of the cleaning tanks are determined according to factors such as the number, the distance, the steel wire feeding speed and the dirt condition on the surface of the steel wire, and generally, the length of the cleaning tanks is 3-20 m, and the width of the cleaning tanks is 0.15-1 m.
The number of the immersed ultrasonic vibrating plates 4 is not less than three, the rated ultrasonic power of each vibrating plate is in the range of 1kW to 3kW, the working frequency is in the range of 18kHz to 50kHz, and the frequency is in the range of 20kHz to 30kHz under most conditions. The length, width and number of the vibrating plates are determined according to the above conditions, and generally, the length of each vibrating plate is 0.6-2 m, and the width is 0.1-0.9 m. The working state of each vibrating plate can be controlled independently.
Wherein, the cleaning liquid is stored in the liquid storage tank 6 and the auxiliary liquid storage tank 7. In general, QingThe volume of the washing liquid storage tank 6 is 3-20 m3The volume of the auxiliary liquid storage tank is less than 10m3.

As the cleaning process progresses, the cleaning effectiveness of the cleaning solution gradually decreases and eventually becomes ineffective, polluting the environment and losing a large amount of active ingredients if discharged. Therefore, the invention designs a system and a method for recovering the ineffective cleaning liquid, the ineffective cleaning liquid can be repeatedly used after being treated, and waste liquid is not discharged to the outside.
As shown in figure 3, the recovery system of the ineffective cleaning liquid of the invention is mainly composed of a dosing tank 11, a dosing pump 12, a recovery processing tank 13, a filtering pressure pump 16, a filtering machine 17 and the like which are connected in sequence.

The recovery processing method of the ineffective cleaning liquid is an oxidation precipitation separation method. The treating agent is an oxidant, and the agent and Fe in the ineffective cleaning liquid2+Ion generation reaction: generated byFe3+And PO in spent cleaning solution4 3-Reaction: thereby removing Fe in the liquid2+Ions, large amount of H remaining in the original spent cleaning solution3PO4And other effective components are retained. The treated liquid is sent back to the liquid storage tank 6 or the auxiliary liquid storage tank 7 through the booster pump 16, the filter 17 and the pipeline 18, and the effective components are complemented through assay adjustment, so that the original ineffective cleaning liquid can be recovered to use again. Precipitated FePO4Making into cake with filter. Due to FePO4The water-soluble organic acid water soluble paint is extremely difficult to dissolve in water under natural conditions, and cannot cause re-pollution to the environment, so that the damage to the environment caused by equipment use can be reduced to the minimum.
The cleaning liquid used in the invention is a water-soluble acid cleaning liquid which is specially developed and can be recycled by an oxidation precipitation method, the main component of the cleaning liquid is industrial phosphoric acid, and the content of the industrial phosphoric acid is controlled between 10 percent and 30 percent (weight ratio) according to the surface condition of a cleaned steel wire. In addition, the cleaning solution can also be used together with a JXA-2 additive developed by people. The main functions of the additive are as follows: (1) corrosion inhibition, (2) reducing the surface tension of the cleaning solution, improving the permeability of the cleaning solution, and (3) shielding harmful ions and stabilizing the cleaning effect. The addition amount of the JXA-2 additive is 0.2-0.5% (weight ratio), and the balance is water. The corrosion inhibition rate of the prepared cleaning liquid to carbon steel is more than 90%, and the temperature is between 40 and 70 ℃ during normal use. The cleaning solution is used at the temperature below 70 ℃, has extremely low corrosion rate to steel and iron metal, and the corrosion rate is lower than 5g/m2H, at such low corrosion rates, it is believed that the cleaning solution only acts on the oxide layer and other dirt on the wire surface during the cleaning process, but not on the wire surfaceCorroding the metal substrate. The mechanism of removing the oxide layer by the cleaning liquid is as follows: ， ， the other dirt is removed mainly by utilizing the dispersion and emulsification performance of the cleaning solution.
Phosphoric acid in the cleaning solution is extremely difficult to evaporate into the air within the cleaning temperature range, and reaction capable of generating gas is extremely rare in the cleaning process, so that harmful gas such as acid mist and the like evaporated into the ambient air is extremely little, and practice proves that the cleaning solution does not cause harm to ambient equipment and personnel, and is the cleaning solution for clean production.
Because the acidity of the phosphoric acid is weak, the cleaning solution is only used for cleaning the surface of the steel wire, a long time is needed, generally 10-20 minutes is needed, and the cleaning efficiency cannot meet the production requirement. Therefore, the method for transmitting the high-power ultrasonic waves into the cleaningliquid is adopted, the cleaning speed is greatly improved, the high-temperature and high-pressure impact caused by the cavitation effect generated on the surface of the steel wire when the ultrasonic waves are transmitted in the cleaning liquid greatly promotes the peeling, dispersing and emulsifying processes of dirt on the surface of the steel wire, meanwhile, the reaction process of acid liquid and oxide is greatly accelerated, the cleaning time is reduced to be less than 1.5 minutes, the cleaning process can be completed only 3-5 seconds for certain types of steel wires, and the requirement for quickly cleaning the surface of the steel wire is met.
Fe dissolved in the cleaning liquid along with the cleaning process2+The ions will increase gradually when Fe2+When the ion concentration reaches a certain degree, the cleaning effect of the cleaning liquid can be obviously reduced and the cleaning requirement of the steel wire can not be met, and at the moment, the cleaning liquid needs to be recycled. Fe in per liter of cleaning liquid in normal use2+The content is less than 45g, the pH value of the cleaning solution is controlled to be 0.5-1.5, and Fe in each liter of cleaning solution after recovery treatment2+And Fe3+Should be present in an amount of no more than 5 grams.
