Description

Technical Field

[0001] The utility model belongs to the technical field of metal electroplating, and in particular relates to a filter for producing chemical electroplating solution. Background Art

[0002] The electroplating liquid filter is a machine specially used for electroplating liquid filtration. It is mainly used to remove impurities, sediments and other pollutants in the electroplating liquid to improve the quality of electroplating and extend the life of the electroplating liquid. In electroplating processing (such as metal electroplating), the electroplating liquid itself is an important process material. The impurities and pollutants in it will have a great impact on the quality of electroplating. Therefore, it is necessary to use an electroplating liquid filter to filter the electroplating liquid to ensure the stability and effect of the electroplating process.

[0003] The Chinese patent application number CN202321155761.5 discloses a plating liquid filter, including a base, a support plate fixedly mounted on the inner side of the base, a pressure pump fixedly mounted on the top of the support plate, an output pipe fixedly mounted on the output end of the pressure pump, and a pump fixedly connected to one end of the output pipe. When filtering the plating liquid, the contaminated plating liquid is input into the pump through the first liquid inlet pipe, and then a part of it is poured into the interior of the second filter cartridge, and then the plating liquid flows into the third liquid inlet pipe through the first valve at the bottom of the second filter cartridge.

[0004] As the applicant conducted further research, it was found that this technical solution would bring in gas during the removal or installation of the filter element. In order to prevent the gas from entering the subsequent plating tank and affecting the electroplating quality of the metal, it was necessary to manually knock the filter cartridge repeatedly. This exhaust treatment method, on the one hand, would cause certain damage to the filter due to knocking. On the other hand, this method had low exhaust efficiency, incomplete exhaust, and weak reliability. Utility Model Content

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A filter for chemical plating solution production, comprising:

[0007] Filter cartridges;

[0008] A base, the bottom of which is connected with a liquid inlet valve;

[0009] The top cover has an exhaust passage and a liquid discharge pipe extending into the filter cartridge on the inner top surface;

[0010] The filter element is arranged in the filter cartridge and is used for removing impurities from the electroplating solution. The end of the drain pipe is connected to the filter element.

[0011] Furthermore, it also includes a mounting frame, and a plurality of supporting legs are connected to the outer periphery of the filter cartridge, and the supporting legs are connected to the upper end of the mounting frame.

[0012] Furthermore, the mounting frame is fixedly connected with a high-pressure pump body, and the high-pressure pump body is connected to the liquid inlet valve through a high-pressure pipe.

[0013] Furthermore, an exhaust valve is provided on the side of the filter cartridge, and the exhaust channel is connected to the exhaust valve.

[0014] Furthermore, the high-pressure pipe is connected to a pressure gauge.

[0015] Furthermore, a liquid temperature gauge is provided on the filter cartridge.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] An exhaust channel is added to the top cover so that the residual air in the filter can be discharged to the outside through the exhaust channel. Due to the action of the high-pressure pump body, the pressure of the plating liquid in the filter cartridge is greater than the external atmospheric pressure, so the plating liquid will flow through the exhaust channel and the air will be discharged. After the air is discharged, the plating liquid filtering work can be carried out by closing the exhaust valve, which provides a guarantee for the subsequent normal electroplating operation and electroplating quality.

For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0025] like Figure 1 - Figure 3 As shown, a filter for chemical plating solution production of the utility model comprises a filter cartridge 1, a base 2, a top cover 3 and a filter element 4;

[0026] The filter cartridge 1 is a conventional model in the industry, such as a polypropylene wire-wound filter element 4. It is detachably placed in the filter cartridge 1;

[0028] The inner top surface of the top cover 3 is provided with an exhaust passage 30 and a liquid discharge pipe 31 extending into the filter cartridge 1;

[0029] The filter element 4 is used for removing impurities from the electroplating solution, and the end of the drain pipe 31 is connected to the filter element 4 .

[0030] In addition, a mounting frame 5 is provided, and a plurality of supporting legs 10 are connected to the outer periphery of the filter cartridge 1 , and the supporting legs 10 are connected to the upper end of the mounting frame 5 .

[0031] Specifically, the mounting frame 5 is fixedly connected with a high-pressure pump body 6, which is connected to the liquid inlet valve 20 through a high-pressure pipe 7. An exhaust valve 11 is provided on the side of the filter cartridge 1, and an exhaust channel 30 is connected to the exhaust valve 11. Due to the action of the high-pressure pump body 6, the air pressure borne by the electroplating liquid in the filter cartridge 1 is greater than the external atmospheric pressure, so the electroplating liquid will flow through the exhaust channel 30, and the air will be discharged. After the air is discharged, the electroplating liquid filtering work can be carried out by closing the exhaust valve 11, which provides guarantee for the subsequent normal electroplating operation and electroplating quality.

[0032] The additional exhaust method of the filter does not require manual repeated knocking of the outer wall of the filter cartridge 1, which can avoid damage to the filter cartridge 1, and its exhaust reliability is enhanced and the exhaust is more thorough.

[0033] In addition, a pressure gauge 70 is connected to the high-pressure pipe 7, and a liquid temperature gauge 12 is provided on the filter cartridge 1. By observing the pressure gauge 70 and the liquid temperature gauge 12, the state of the electroplating liquid in the filter, such as temperature and pressure, can be understood. In case of insufficient pressure, the pointer in the pressure gauge 70 can give a prompt to the operator, making it convenient for the operator to adjust the pressure of the high-pressure pump body 6.
