Problems solved by technology

[0005] It can be seen from this that once metal ions are precipitated in the main tank, it will be necessary to stop production and replace with a new liquid medicine, and the time for changing the liquid medicine is too long, all of which have resulted in an increase in production costs.

The filtering device comprises a main groove, a liquid inlet pipe, a filter, a liquid outlet pipe, wherein the main groove is used for containing solution, the liquid inlet pipe is provided with a first inlet and a first outlet, the first inlet is arranged below the liquid level of the solution in the main groove, the first outlet is connected to the filter, the filter is used for filtering the solution, the liquid outlet pipe is provided with a second inlet and at least one second outlet, the second inlet is connected to the filter, the at least one second outlet is positioned in the main slot and faces to the bottom of the main slot obliquely or vertically, at least the first inlet in the first inlet, the first outlet, the second inlet and the second outlet is connected with a conduit, the surface of the conduit is provided with a plurality of through holes, and the plurality of through holes face to at least two different directions. The filtering device and the filtering method can be used for filtering.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to a filtration device and a filtration method. Background technique [0002] In modern manufacturing, it is often necessary to use chemicals and process workpieces by means of chemical reactions. For example, in the field of circuit board manufacturing, it is necessary to use chemical agents for electroless copper plating, metal plating and other processes. In these processes, in order to ensure that the chemical agents used have good and stable chemical activity, it is generally necessary to use a filter device to circulate and filter the chemical agents. [0003] The existing filtering device is described below with the nickel-palladium-gold process that needs to be used when making thin special circuit boards. Such as figure 1 As shown, in the filter device of nickel-palladium-gold process, there is a main tank 1 providing a chemical reaction place, and an auxiliary tank 2...
