Description

Pcb board recursive filter

Technical field：

This utility model is related to pcb board and manufactures auxiliary equipment field, specifically refers to use in a kind of pcb board fabrication processing Carry out the recursive filter of impurity screening.

Background technology：

Pcb board (Printed Circuit Board), Chinese is printed wiring board, also known as printed circuit board (PCB), is electricity One of vitals of son industry, plays a part for each electronic devices and components to realize electric interconnection.Pcb board is in manufacturing process Surface can be sticked the impurity such as copper ashes, if being carried out not in time filtering, the hole position of the copper coin of PCB can be caused to be blocked up by copper ashes Plug, the quality of impact product.Existing way is that pcb board is transported to liquid cylinder, and liquid cylinder is directly connected to tap water, Ran Hou Pass through directly flushing with tap water pcb board in the case of there is no filter, but in the middle of tap water, contain multiple float and mushroom thing The impurity such as matter, directly rinsing pcb board, the impurity such as float and mushroom material can be attached on pcb board, can cause pcb board on the contrary Secondary pollution.

Utility model content：

For the drawbacks described above of prior art, this utility model carries out targeted design, provides one kind to be arranged on liquid cylinder On pcb board recursive filter, by tap water being carried out with efficiently accurate contaminant filter it is ensured that two will not be caused to pcb board Secondary pollution.

The technical solution adopted in the utility model is：A kind of pcb board recursive filter, including being connected on running water pipe Water inlet pipe and the return pipe being connected on liquid cylinder.Also include many filter tubes being connected between water inlet pipe and return pipe, often Three filter cylinders are arranged with root filter tube, described filter cylinder is by top cover, and the housing being connected with top cover thread seal is formed, Also be placed with inner core in the inside of housing, three filter cylinders from water inlet pipe to the direction of return pipe set gradually for single filter cylinder, Cascade filtration cylinder, three-stage filtration cylinder.

The measure taken further is：Described top cover offers water inlet and outlet respectively in the left and right sides, wherein The outer end of water inlet is docked with the water inlet end of filter tube, and the inner of water inlet is docked with inner core, the outer end of outlet and filter tube Water side docking, the inner of outlet is docked with housing.

Specifically, described single filter cylinder is placed with separation net in the middle of inner core.

Specifically, described cascade filtration cylinder is placed with cotton core set in the middle of inner core.

Specifically, described three-stage filtration cylinder is placed with activated carbon in the middle of inner core.

Described water inlet pipe is also equipped with pump table at middle part.

This utility model, by such design, is had the advantage that：Structure is simple, reasonable in design, with impurity Tap water flowed into by water inlet pipe, the filter of the multistage filtering cylinder on inherent filtration pipe is net, formed totally pure tap water again by Return pipe flows out, and succinctly facilitates very much.Filter cylinder is demountable structure, periodically can take apart clearly inner core during use Wash, save the cost again buying filter cylinder, enormously simplify the operational maintenance operation of filter cylinder.

In order to more fully understand and implement, describe this utility model below in conjunction with the accompanying drawings in detail.

Brief description：

Fig. 1 is overall structure diagram of the present utility model；

Fig. 2 is cartridge structure schematic diagram of the present utility model.

In figure, 1, water inlet pipe, 2, return pipe, 3, filter tube, 4, filter cylinder, 41, top cover, 411, water inlet, 412, outlet, 42nd, housing, 43, inner core, 5, pump table.

Specific embodiment：

In conjunction with shown in Fig. 1, Fig. 2, structure of the present utility model includes the water inlet pipe 1 being connected on running water pipe and is connected to Return pipe 2 on liquid cylinder, also includes many filter tubes 3 being connected between water inlet pipe 1 and return pipe 2, on every filter tube 3 It is arranged with three filter cylinders 4, described filter cylinder 4 is by top cover 41, and the housing 42 being connected with top cover 41 thread seal is formed, The inside of housing 42 is also placed with inner core 43, and three filter cylinders are set gradually as single filter from water inlet pipe 1 to the direction of return pipe 2 Cylinder, cascade filtration cylinder, three-stage filtration cylinder.

Described top cover 41 offers water inlet 411 and outlet 412 respectively in the left and right sides, wherein water inlet 411 Outer end is docked with the water inlet end of filter tube 3, and the inner of water inlet 411 is docked with inner core 43, the outer end of outlet 412 and filter tube 3 water side docking, the inner of outlet 412 is docked with housing 42.

Described single filter cylinder is placed with separation net in the middle of inner core, and separation net, as the device of preliminary purification, plays Intercept the effect of the impurity such as larger particles in tap water,

Described cascade filtration cylinder is placed with cotton core set in the middle of inner core, and cotton core set, as the device of double purification, plays Intercept the effect of the impurity such as general granule in tap water.

Described three-stage filtration cylinder is placed with activated carbon in the middle of inner core, and activated carbon, as the device of careful purification, plays Intercept the effect of the impurity such as fine particle in tap water.

Described water inlet pipe 1 is also equipped with pump table 5 at middle part, and pump table 5 is as the machinery conveying liquid or making liquid be pressurized Computing device, plays a part the water yield of the tap water flowing through to be detected and records, facilitates checking of staff.

Tap water flows into water inlet pipe 1 through pump table 5, then proceeds to filter tube 3 respectively, and tap water sequentially passes through on chimney filter 3 Level cartridge filter, cascade filtration cylinder, three-stage filtration cylinder contaminant filter from coarse to fine is it is ensured that finally flowing on return pipe 2 is not Impure tap water, prevents impurity from sticking or is blocked on pcb board, and then affects the processing of postorder pcb board.And daily It is only necessary to unclamp the housing 42 of each filter cylinder 4 in the screw thread of top cover 41 during maintenance, you can housing 42 is torn open from filter cylinder 4 Unload down, the convenient inner core 43 that takes out is carried out, and need not disassemble whole piece filter tube 3, enormously simplify daily guarantor Support operation.
