Description

Technical Field

[0001] The utility model belongs to the technical field of metal electroplating, and in particular relates to a filtering device for producing electroplating liquid medicine. Background Art

[0002] The plating industry is an important processing industry in my country. Currently, it is mainly zinc plating, chromium plating, nickel plating and copper plating, and is concentrated in industrial fields such as machinery manufacturing, light industry, electronics, aerospace, and instrumentation. Electroplating processing usually places the object to be plated in an electrolytic cell containing the corresponding chemical electrolyte, and forms an electroplating layer on the surface of the object to be plated by applying electricity. During the electroplating process, electroplating liquid must be added to the electrolytic cell for different electroplating products. The quality of the electroplating liquid also directly affects the electroplating effect.

[0003] The electroplating process has certain requirements on the purity of the solution in the electroplating tank. If the purity of the solution is not high, the electroplating quality will be poor. In addition, the solution produces reaction residues, which must be filtered and removed, otherwise it will have an adverse effect on the electrochemical reaction in the electroplating tank. The electroplating solution usually needs to be filtered multiple times before it can be used. At present, the electroplating solution is usually put into a filter or filtering equipment for filtration.

[0004] A Chinese patent with application number CN202021662769.7 discloses a filtering device for the production of electroplating solutions, comprising a workbench, a feeding device, a filtering device, a rotating device and a cleaning device. The feeding device is installed inside the workbench, and one end of the feeding device is connected to the filtering device. The filtering device, the rotating device and the cleaning device are arranged on the workbench in sequence along the length direction of the workbench. The rotating device comprises a first motor, a reinforcement plate, a rotating shaft, a mounting plate, an electric push rod, a connecting bracket, a second motor, a transmission shaft, two sliders and two clamping plates. The reinforcement plate is fixed on the inner bottom wall of the workbench, and the first motor is vertically mounted on the inner bottom wall of the workbench through the reinforcement plate, and the output end of the first motor is fixedly connected to the bottom end of the rotating shaft, and the rotating shaft is vertically mounted on the workbench.

[0005] With further research by the applicant, it was found that when the filtration device of this technical solution filters the electroplating solution, the residue easily clogs the filtration structure, and the lack of a scraping structure on the filtration structure makes it difficult to quickly scrape off the residue on the filtration structure, affecting the filtration effect, which needs further improvement.

[0033] like Figure 1 - Figure 5As shown, the utility model is a filtering device for electroplating solution production, comprising a housing 1, a filtering component 2, a cleaning component 3 and a driving component 4;

[0034] The housing 1 has a liquid inlet 10 and a liquid outlet 11, a support leg 15 is connected to the bottom of the housing 1, and a hydraulic instrument for monitoring the water inside the filter device is connected to the housing 1;

[0035] The cleaning component 3 is placed in the filter component 2, and the cleaning component 3 has bristles 34 that contact the inner wall of the filter component 2;

[0036] The driving component 4 is connected to the housing 1, and the filtering component 2 is connected to the power output end of the driving component 4;

[0037] After the cleaning component 3 is acted upon by the driving component 4 , impurities attached to the inner wall of the filter component 2 are brushed away by the bristles 34 .

[0038] The electroplating solution is pumped into the housing 1 through the liquid inlet 10 and is removed by the filter component 2. The impurities are intercepted on the inner wall of the filter component 2, and the filtered clean water or solution flows out from the liquid outlet 11. When the impurities on the inner wall of the filter component 2 accumulate more and more, the pressure difference at the liquid inlet or outlet 11 reaches a preset value or the cleaning time is reached, the cleaning component 3 starts to operate and starts to clean the filter component 2.

[0039] The cleaning component 3 is driven to rotate by the driving component 4 to prevent the filter component 2 from being blocked by impurities, thereby improving the filtering efficiency and extending the service life of the filter component 2.

[0040] Specifically, Figure 4 , Figure 5 As shown, the cleaning assembly 3 includes a rotating shaft 30 coaxially arranged with the filtering assembly 2 and connected to the driving assembly 4 , and a rotating side plate 31 arranged on the side of the rotating shaft 30 , and bristles 34 are arranged on the rotating side plate 31 .

[0041] The cleaning component 3 also includes a connecting part 32 for connecting the rotating shaft 30 and the rotating side plate 31. The connecting part 32 can be divided into a connecting outer rod and a connecting inner rod, which are coaxially sleeved together. In order to enhance the cleaning efficiency of the cleaning component 3 on the inner wall of the filter component 2, an elastic member 33, such as a spring, is provided on the outer periphery of the connecting outer rod. When the cleaning component 3 is driven and rotated by the driving component 4, the connecting outer rod and the connecting inner rod slide relative to each other with different rotation speeds, so that the connecting part 32 is extended or shortened, and the degree of close contact between the bristles 34 and the inner wall of the filter component 2 is changed. With such a setting, when the internal cleaning work has not been started for a long time or the impurity content of the water is large, the output power of the driving component 4 can be increased for adjustment.

[0042] Among them, the rotating side plates 31 are set to at least two components, and each group of rotating side plates 31 extends along the length direction of the filter component 2. When two rotating side plates 31 are set, they are symmetrical to increase the cleaning effect. The multiple rotating side plates 31 can also be set into a closed ring shape and bristles 34 can be arranged, which can further increase the contact area between the bristles 34 and the entire filter component 2 and improve the cleaning effect.

[0043] In addition, if Figure 4 As shown, the filter assembly 2 has a mounting frame 20, the bottom of the rotating shaft 30 is connected to the mounting frame 20, and a groove is provided outside the center of the mounting frame 20 for the end of the rotating shaft 30 to extend into, and the cleaning assembly 3 can be installed and positioned through the groove.

[0044] A pull handle 21 is also connected to the upper end of the filter assembly 2. The pull handle 21 can be symmetrically arranged in two groups. When the filter assembly 2 needs to be replaced, the cleaning assembly 3 can be taken out from the filter assembly 2 by applying force through the pull handle 21.

[0045] The top of the housing 1 is provided with a flange 12 , the inner side of the flange 12 is provided with a sealing ring, and the driving assembly 4 is mounted on the upper end of the flange 12 , and the driving assembly 4 is composed of a motor and a reduction mechanism.

[0046] In addition, a drain port 13 is provided at the bottom of the housing 1. When the device is used for a period of time or when targeted cleaning work is performed, the impurities brushed off flow out from the drain port 13. A valve is provided at the drain port 13.

[0047] An electrical control box 14 is provided on the side of the housing 1, and the electrical control box 14 has the function of controlling the rotation speed and forward or reverse rotation of the driving component 4, wherein the hydraulic instrument is electrically connected to the electrical control box 14, and when the pressure difference at the liquid inlet or outlet 11 reaches a preset value, the cleaning component 3 starts to operate and starts to clean the filter component 2.
