Abstract

An integrated parallel-type filter with convenient maintenance is characterized in that two improved basket filters are connected in parallel directly, and are connected with a bent pipe through two three-way valves or a plurality of two-way valves; a filtering screen cylinder and an end cover are circumferentially sealed by a seal ring; the improved filter has the advantages of reasonable and compact structure, high integration level, easy industrial manufacturing, good filterability, easy seal, convenient disassembly and clean and multiple schemes for choice, can be directly applied to the industrial pipelines in fields of chemical industry, pharmacy, food, water supply and sewage treatment, and is used for effectively filtering solid impurities.

Description

Integrated parallel filter

Affiliated technical field

The utility model relates to a kind of integrated parallel filter, and it belongs to the art of filters of pipe-line equipment.Be applicable to that the on-line filtration solid impurity is used in the fluid line in fields such as chemical industry, pharmacy, food, water supply, waste water control.

Background technology

At present, known general chemical industry, food, pharmacy, supply water, the filter of online use in the field fluid lines such as waste water control, mainly contain Y type and basket filter, they are connected in the service pipe by flange or hydraulic quick coupler usually, purpose is constantly to filter solid impurity, but because these filters do not have initiatively to drain the function of impurity, so be easy to take place to stop up or escape of impurities, thereby the essential cleaning filter that stops production, and this class standard filter is not to be used for quick detach, quick change, clean for existing field boundary and also bring a lot of inconvenience, and the screen tube of this class filter and end cap seal are relatively poor, are easy to take place impurity and refrigerant leakage.Can check CN200520019129.3 etc.

Therefore one of preceding border that solves this class problem is: directly adopt two integrated parallel connections and be convenient to the filter dismantling and clean, and improve the sealing means of screen tube and end cap, and strengthening sealing property, this will be very with practical value.

Summary of the invention

After overcoming existing plugged filter, need the cleaning that stops production, and strainability is poor, be not easy to the problem changing and dismantle, the novel employing of this usefulness is parallel, integrated, the design of the filter of quick detach, redesign screen tube and end cap seal reach cleanings, replacing does not stop production strainability (filter area, impurity parking space size, sealing property), dismounting, clean convenient all improve more and convenient.

The technical scheme that its technical problem that solves the utility model adopts is: adopt two improved basket filters directly in parallel, and be connected with bend pipe by two triple valves or a plurality of two-port valve, only allow one of them filter work during work, another filter is in the cleaning stand-by state, when taking place to stop up, two triple valves of turn or a plurality of two-port valve, allow another filter work, blocked filter cleans or dismantles, do not influence ordinary production, filtering net cylinder is installed be designed to the sealing of circumferential sealing circle, and the end face seal of lid is designed to the sealing of circumferential sealing circle, thereby seal more reliable, and sealing load is little, and reduces end cap screw number, or is that open washer adds the revolution screw with the end cap screw designs, to increase quick detach, the end cap back is provided with spring in order to compress filtering net cylinder.

The beneficial effects of the utility model are, rational in infrastructure, compact, strainability is good, are easy to sealing, dismounting, clean convenient, lower than the basket filter cost in parallel of producing existing field boundary assembling, more optimized structure, performance is better.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1, Fig. 2, Fig. 6, Fig. 7 are integrated parallel filter of the present utility model and the vertical embodiment schematic diagram of pipe flow path direction.

Fig. 3, Fig. 5 are integrated parallel filter of the present utility model and the parallel embodiment schematic diagram of pipe flow path direction.

Fig. 4 is integrated parallel filter of the present utility model and the embodiment schematic diagram of managing the flow path direction oblique.

Fig. 6 is the parallel integrated filter embodiment schematic diagram that more compact band is incubated outside plate.

Fig. 7 is the compactest square filter, and filtering net cylinder is circular integrated parallel filter embodiment schematic diagram.

Fig. 1, Fig. 2, Fig. 3, Fig. 4 are same level mouth turnover, and Fig. 6 normally import is higher than the outlet use.

What show among the figure is the front view and the left view of same apparatus structure.Show non-same ratio among the figure, filter size dwindles, and pipeline size has suitably been amplified.

Among the figure, 1. import triple valve or two-port valve, 2. shunt filter, 3. outlet triple valve or two-port valve, 4. sealing ring.5. impurity outlet valve.

The specific embodiment

In Fig. 1, fluid enters import triple valve (1) in the direction of arrows, switches to the left side or the right shunt filter (2) through triple valve (1), more after filtering, flow to outlet triple valve (3) and flows out.When filter stops up, import and outlet triple valve are all switched to another shunt filter, turn impurity outlet valve (5) is emitted impurity, and then plugged sereen just can clean or change, thereby does not influence production.Sealing ring (4) is used for end cover and filtering net cylinder, and they all seal on the circumference of cylindrical shell, and sealing load is little, good seal performance; Compress end cap and add the opening washer sets by the revolution screw, end cap is used the spring compression cartridge filter down.Whole parallel integrated filter is symmetrical structure.

In Fig. 2, outlet valve is two two-port valves, and structure is compact.

Fig. 3, Fig. 4, among Fig. 5, shunt filter is two independently improved basket filters, they can split out separately.

In Fig. 5, used four two-port valves, when advantage is the switch filtering device, can not cause working fluid moment cutout.It is also very convenient to split out cleaning simultaneously.

In Fig. 6, two risers can constitute outer heating jacket, and the outer semicanal that can also add some horizontal strokes is certainly used for heating, insulation.Its structure is more compact.

In Fig. 7, filter profile is square, and self-filtering net tube is circular, cover plate is a square-outside and round-inside, mainly is to be convenient to sealing and to be convenient to make, and integrated level is the highest, make the easyliest, it is also very more convenient to add outer insulation, only needs with semicanal dispersedly, get final product along being welded on the filter outside.

All among the embodiment, all do not consider the insulation problem of filter, if insulation, suggestion disperses directly to be welded on the filter urceolus with semicanal, and tube connector and valve all can with twining the heating of copper pipe or interior pipe outward.In order to be incubated, the outside can add the polyester layer.In all schemes, Fig. 6, the scheme optimum of Fig. 7, integrated level is the highest, and cost of manufacture is minimum.

Claims

1. integrated parallel filter, comprise two improved basket filters, filtering net cylinder and baskets, it is characterized in that: described two basket filters are directly in parallel, and be connected with bend pipe by two triple valves or a plurality of two-port valve, filtering net cylinder is the sealing of circumferential sealing circle, the end face seal of lid is the sealing of circumferential sealing circle, and perhaps the end cap screw is that open washer adds the revolution screw, and the end cap back is provided with spring.
