Description

Technical Field

[0001] This utility model relates to the field of electroplating technology, specifically to a self-cleaning device for electroplating bath solutions. Background Technology

[0002] Electroplating is an electrochemical process that deposits a desired coating on a metal surface through electrolysis. Its main purpose is to improve appearance and corrosion resistance. The core principle is the reduction and crystallization of metal ions at the cathode. The electroplating bath is a crucial medium used in the electroplating process for depositing the metal layer.

[0003] Over time, electroplating bath solutions accumulate impurities such as dust, burrs, organic matter, and metal particles. These impurities affect the quality of the electroplated layer, leading to defects such as pitting, burrs, and roughness in the product. Most existing electroplating bath filtration equipment uses filter cartridges. After a period of use, impurities accumulate inside the filter cartridges, requiring the machine to be stopped for cleaning or replacement, thus affecting the normal filtration function of the equipment. Utility Model Content

[0004] To address the above deficiencies, this utility model provides a self-cleaning device for electroplating bath solutions to solve the problem of impurity filtration in electroplating bath solutions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A self-cleaning device for electroplating bath solution, comprising: Filter; The liquid inlet is located at the bottom of the filter. A mounting plate is installed inside the filter. The filter cartridges are a set, inserted on both sides of the fixed plate with the opening facing downwards, and are equipped with a cleaning mechanism inside; Drive unit one is installed on one side of the bottom of the filter; A rotating shaft is movably inserted at the center of the bottom of the filter, and a drive unit is used to drive the rotating shaft to rotate. The drain pipe is connected at one end to the top of the rotating shaft and at the other end to the filter; The backwash pipe is inserted into one side of the drain pipe and is connected to the drain pipe; The liquid outlet is located at the top of the filter.

[0006] Furthermore, the cleaning mechanism includes a second drive unit fixed to the top of the filter. A drive shaft is installed on the rotating end of the second drive unit, and an adjusting sleeve is movably fitted on the drive shaft. A drive gear is installed on the adjusting sleeve. A set of cleaning brushes is movably inserted inside a set of filter cartridges. A set of interlaced driven gears is installed on the upper end of each set of cleaning brushes. The second drive unit is an electric motor, and the drive shaft is a splined shaft, which facilitates the up-and-down movement of the adjusting sleeve. During backwashing of the filter cartridges, the second drive unit can drive the adjusting sleeve to rotate through the drive shaft, and drive the driven gear 15 and the corresponding cleaning brushes to rotate through the drive gear, thereby improving the backwashing effect.

[0007] Furthermore, an electric actuator is installed at the top rear end of the filter. The telescopic end of the electric actuator is connected to an adjusting claw that moves the adjusting sleeve up and down. The electric actuator uses an electric push rod. The electric actuator can adjust the position of the adjusting sleeve through the adjusting claw, thereby causing the second drive device to alternately drive a set of cleaning brushes to rotate and clean.

[0008] Furthermore, the rotating end of the drive device is connected to the rotating shaft via a synchronous belt, thus achieving synchronous transmission between the drive device and the rotating shaft.

[0009] Furthermore, an electromagnetic control valve is installed on the sewage pipe, and a differential pressure gauge is installed on the filter. The differential pressure gauge is used to detect the pressure difference between the contaminated and clean sides of the filter cartridge.

[0010] Furthermore, a set of backflushing pipes are each equipped with a rubber sealing joint at the upper end to achieve a sealing effect.

[0011] Furthermore, the bottom of the filter is mounted on a frame.

[0012] This utility model provides a self-cleaning device for electroplating bath liquid, which has the following beneficial effects: the electroplating bath liquid is drawn into the filter through the inlet, enters a set of filter cartridges through the fixed plate, and the liquid flows from the inside to the outside of the filter cartridges and flows out from the outlet, realizing the self-cleaning of the electroplating bath liquid. Impurities are trapped inside the filter cartridges. When the pressure of the filtered liquid gradually increases, when the pressure difference between the contaminated side and the clean side of the filter cartridge reaches the set value, the automatic backwashing mode is activated. The drive device drives the backwashing pipe to align with the filter cartridges and opens the electromagnetic control valve, so that a pressure difference is formed between the outside of the filter cartridge being cleaned and the sewage discharge, thereby realizing backwashing. The backwashing of a set of filter cartridges is performed alternately, so as to realize filtration without stopping the machine. Attached Figure Description

The liquid flows from the inside to the outside of the filter cartridge 4 and flows out from the outlet 9, realizing self-cleaning of the electroplating bath liquid. Impurities are trapped inside the filter cartridge 4. When the pressure of the filtered liquid gradually increases, when the pressure difference between the contaminated side and the clean side of the filter cartridge 4 reaches the set value, the automatic backwashing mode is activated. The drive device 5 drives the backwashing pipe 8 to align with the filter cartridge 4 through the rotating shaft 6 and the drain pipe 7, and opens the electromagnetic control valve to create a pressure difference between the outside of the filter cartridge 4 being cleaned and the drain. Impurities are automatically discharged through the drain pipe 7, thereby realizing backwashing. The backwashing of a set of filter cartridges 4 is performed alternately, which can realize filtration without stopping the machine.

[0018] like Figure 4 and Figure 5 As shown, the second drive device 10 uses an electric motor, and the drive shaft 11 uses a spline shaft to facilitate the up-and-down movement of the adjusting sleeve 12. When the filter cartridge 4 is backwashed, the second drive device 10 can drive the adjusting sleeve 12 to rotate through the drive shaft 11, and drive the driven gear 15 and the corresponding cleaning brush 14 to rotate through the drive gear 13, thereby improving the backwashing effect.

The telescopic end of the electric actuator 16 is connected to an adjusting claw 17 that moves the adjusting sleeve 12 up and down. The electric actuator 16 adopts an electric push rod. The electric actuator 16 can adjust the position of the adjusting sleeve 12 through the adjusting claw 17, thereby causing the drive device 2 10 to alternately drive a set of cleaning brushes 14 to rotate and clean.

[0020] In some embodiments, the rotating end of the drive device 5 is connected to the rotating shaft 6 via a synchronous belt 18 to achieve synchronous transmission between the drive device 5 and the rotating shaft 6.
