Description

Technical Field

[0001] The present application relates to the technical field of plating solution recovery, and in particular to a low-temperature evaporation plating solution recovery device. Background Art

[0002] During the production process of steel strips, plating solutions are used. After the existing plating solutions are used, they are usually processed by manufacturers with treatment qualifications. However, this method does not treat the plating solutions and directly hands them over to qualified manufacturers for treatment, resulting in a large consumption of water resources. Summary of the Invention

[0003] In view of the deficiencies in the prior art, one of the objectives of the present application is to provide a low-temperature evaporation plating solution recovery device, which has the advantage of being able to reduce water resource consumption.

[0004] The above objective of the present application is achieved through the following technical solutions:

[0005] A low-temperature evaporation plating solution recovery device includes a control system, a stirring mechanism, a low-temperature condenser, a concentrated water bucket, and a fresh water bucket. After the plating solution is stirred by the stirring mechanism, it enters the low-temperature condenser through a pipeline. The concentrated water is discharged into the concentrated water bucket through a pipeline, and the condensed water is discharged into the fresh water bucket through a pipeline. The stirring mechanism includes a stirring bucket and a stirring component, and the stirring component is used to stir the plating solution in the stirring bucket. The control system includes a collection module, a judgment module, and a dosing module. The collection module is used to collect the liquid state in the stirring bucket, and the judgment module is used to judge whether there are bubbles in the liquid state collected by the collection module. If there are bubbles, the dosing module doses an antifoaming agent into the stirring bucket.

[0006] By adopting the above technical solutions, when treating the plating solution, through the operations of first stirring and adding an antifoaming agent, the probability of generating bubbles in the low-temperature condenser can be reduced. At the same time, through the setting of the low-temperature condenser, the water in the plating solution can be separated, thus saving water resources.

[0007] In a preferred example of the present application, it can be further configured as follows: a drain port is provided in the stirring bucket, the drain port is arranged at the bottom of the stirring bucket, a temporary storage bucket is provided below the stirring bucket, the drain port is connected to the temporary storage bucket through a pipeline, and a filtering component is provided at the drain port.

[0008] By adopting the above technical solutions, the setting of the filtering component and the drain port makes it convenient to discharge the plating solution.

[0009] In a preferred example of the present application, it can be further configured as follows: after dosing the antifoaming agent, the collection module collects the liquid state in the stirring bucket again, and the judgment module makes a judgment on it. If there are no bubbles, the temporary storage bucket is connected to the stirring bucket under the stirring state.

[0010] By adopting the above technical solution, in the stirring state, the temporary storage barrel and the stirring barrel are connected, which can reduce the probability of impurities entering the temporary storage barrel.

[0011] In a preferred example of the present application, it can be further configured that: before the stirring barrel and the temporary storage barrel are connected, the stirring component rotates clockwise and counterclockwise at intervals, and when the stirring barrel and the temporary storage barrel are connected, the rotation direction of the stirring component remains unchanged.

[0012] By adopting the above technical solution, the stirring component rotates clockwise and counterclockwise at intervals, making it easier for the plating solution to generate foam. When the temporary storage barrel and the stirring barrel are connected, the rotation direction of the stirring component remains unchanged, so that the impurities in the plating solution are not easily introduced into the temporary storage barrel under the action of centrifugal force.

[0013] In a preferred example of the present application, it can be further configured that: a receiving groove is provided at the bottom of the stirring barrel, and the receiving groove is close to the barrel wall of the stirring barrel.

[0014] By adopting the above technical solution, the existence of the receiving groove enables the collection of impurities that move to the barrel wall under the action of centrifugal force.

[0015] In a preferred example of the present application, it can be further configured that: the control system includes a metering module, the metering module is used to count the liquid increase rate v in the temporary storage barrel, the judgment module obtains the speed v and makes a judgment. If the speed v is less than the standard value, a cleaning prompt is given.

[0016] By adopting the above technical solution, when the speed v is less than the standard value, it indicates that the filtering component is blocked and needs to be cleaned.

[0017] In a preferred example of the present application, it can be further configured that: the receiving groove is connected to the outside through a pipeline. After the cleaning prompt is given, the acquisition module collects the liquid level in the stirring barrel and sends it to the judgment module. The judgment module judges the liquid level. When the preset value is reached, the connection between the stirring barrel and the temporary storage barrel is cancelled, and the pipeline connecting the receiving groove and the outside is opened to discharge the impurities.

[0018] By adopting the above technical solution, when the filtering component is blocked, after the liquid level in the stirring barrel drops to the preset liquid level, the connection between the stirring barrel and the temporary storage barrel is cancelled, and the pipeline connecting the receiving groove and the outside is opened to discharge the impurities, so that the discharge effect of the impurities is better.

[0019] In a preferred example of the present application, it can be further configured that: after cleaning, the stirring duration of the stirring component before the stirring barrel and the temporary storage barrel are connected is extended.

[0020] By adopting the above technical solution, that is, after cleaning, when the plating solution of the next batch enters the stirring barrel, by extending the stirring time, the impurities attached to the filtering component can be removed.

[0021] In a preferred example of the present application, it can be further configured as follows: when the extended stirring duration ends, the stirring barrel and the temporary storage barrel are connected for a period of time, and the speed v is judged. If it is greater than the speed v of the previous batch and less than the standard value, the connection between the stirring barrel and the temporary storage barrel is cancelled, and the stirring component rotates again in a rotational mode with clockwise rotation and counterclockwise rotation arranged at intervals. If it is not greater than the speed v of the previous batch, an inspection prompt is given.

[0022] By adopting the above technical solution, when the speed v is greater than the speed v of the previous batch and less than the standard value, it indicates that the impurities on the filtering component have been removed. Therefore, by rotating at intervals again, the impurities on the filtering component are further removed. When the speed v is not greater than the speed v of the previous batch, it indicates that the stirring does not have a cleaning effect on the filtering component (such as the impurities are firmly attached), and manual inspection is required.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] Referring to Figure 1 and Figure 2 , a low-temperature evaporation plating solution recovery device disclosed in the present application includes a control system, a stirring mechanism, a low-temperature condenser 3, a concentrated water barrel 4, and a fresh water barrel 5. The low-temperature condenser 3 is a vacuum low-temperature condenser 3. After the plating solution is stirred by the stirring mechanism, it enters the low-temperature condenser 3 through a pipeline. The concentrated water is discharged into the concentrated water barrel 4 through a pipeline, and the condensed water is discharged into the fresh water barrel 5 through a pipeline. The stirring mechanism includes a stirring barrel 1 and a stirring component. The stirring component rotates under the drive of a motor. The stirring component includes a stirring shaft and stirring blades installed on the stirring shaft. The stirring component is used to stir the plating solution in the stirring barrel 1.

[0028] Inside the stirring barrel 1, there are partition plates 11 and a drain port 13. The drain port 13 is arranged at the bottom of the stirring barrel 1 and centered. The drain port 13 penetrates through the partition plate 11, and the pipeline connected to the drain port 13 extends to the drain port 13 on the partition plate 11. Below the stirring barrel 1, there is a temporary storage barrel 2. The drain port 13 is connected to the temporary storage barrel 2 through a pipeline. A filtering component is arranged at the drain port 13. In this embodiment, the filtering component is a filter net. The partition plate 11 is connected to the barrel wall of the stirring barrel 1 and is located above the barrel bottom. There are also through holes 111 on the partition plate 11. The partition plate 11, the barrel bottom, and the through holes 111 form a receiving groove 12, and the through holes 111 are close to the barrel wall of the stirring barrel 1.

[0029] Before the stirring barrel 1 and the temporary storage barrel 2 are connected, the stirring component rotates clockwise and counterclockwise at intervals. When the stirring barrel 1 and the temporary storage barrel 2 are connected, the rotation direction of the stirring component remains unchanged (such as always rotating clockwise or counterclockwise).

[0030] The control system includes a collection module, a judgment module, a measurement module, and a dosing module. The collection module is used to collect the liquid state in the stirring barrel 1. The judgment module is used to judge whether there are foams in the liquid state collected by the collection module. If there are foams, the dosing module doses an antifoaming agent into the stirring barrel 1. The collection module can be an image collection device, such as a camera. The dosing module can be a nozzle. The measurement module can be a liquid level sensor.

[0031] After dosing the antifoaming agent, the collection module collects the liquid state in the stirring barrel 1 again, and the judgment module judges it. If there are no foams, when in the stirring state, the temporary storage barrel 2 and the stirring barrel 1 are connected. The measurement module is used to count the liquid increase speed v in the temporary storage barrel 2 (that is, the increase speed of the liquid level height). The judgment module obtains the speed v and makes a judgment. If the speed v is less than the standard value, a cleaning prompt is given.

[0032] The receiving groove 12 is connected to the outside through a pipeline. After giving the cleaning prompt, the collection module collects the liquid level in the stirring barrel 1 and sends it to the judgment module. The judgment module judges the liquid level. When it reaches the preset value, the connection between the stirring barrel 1 and the temporary storage barrel 2 is cancelled, and the pipeline connecting the receiving groove 12 and the outside is opened to discharge impurities.

[0033] After cleaning, the stirring duration of the stirring component before the stirring barrel 1 and the temporary storage barrel 2 are connected is extended. When the extended stirring duration ends, the stirring barrel 1 and the temporary storage barrel 2 are connected for a period of time, and the speed v is judged. If it is greater than the speed v of the previous batch and less than the standard value, the connection between the stirring barrel 1 and the temporary storage barrel 2 is cancelled, and the stirring component rotates in an alternating clockwise and counterclockwise rotation mode again. If it is not greater than the speed v of the previous batch, an inspection prompt is given.

[0034] That is, assume that the current batch for cleaning is batch A, and the speed v at this time is Va. The next batch is batch B. When batch B is stirring with intervals of clockwise rotation and counterclockwise rotation, the stirring duration is longer than that of this step in batch A. After the stirring is completed, the speed Vb is obtained and compared with Va, so as to obtain the cleaning effect on the filter component.

[0035] The implementation principle of this embodiment is as follows: During the treatment, a certain amount of plating solution is transported to the stirring tank 1 for treatment. After the treatment is completed, the plating solution is transported to the temporary storage tank 2, and then the plating solution in the temporary storage tank 2 is transported to the low-temperature condenser 3 for vacuum condensation, so as to obtain concentrated water and condensed water.

[0036] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
