Abstract
The station has a housing (10) designed as a filter block, and backflushing filters (12, 14) arranged on the housing. A valve (16) i.e. double operative poppet valve, is provided in the filter block for alternately detaching one of the two backflushing filters from a feeder. Set of valves (18) i.e. poppet valves, are provided for connecting an inlet of the backflushing filters with a backflushingconnector. The valve (16) has a larger flow rate than one of the set of valves.
Description
Technical field
The present invention relates to a kind of filter station that is used for underground mining.
Background technology
Such filter station knows and is used to filter the pressure fluid of walking type hydraulic supports device basically for the people.
Summary of the invention
The objective of the invention is to, propose a kind of filter station that is used for underground mining, this filter station can be realized better backflush with lower cost.
This purpose will realize by the described feature of claim 1, and it is characterized in that filter station has the housing that is designed to filtering module, and this housing is provided with first and second reverse washing filters.In filtering module, be provided with first valve, utilize this first valve to make one in first and second reverse washing filters alternately to separate with inflow entrance, and be provided with second valve, utilize this second valve that the inlet of first reverse washing filter is connected with the backflush interface, and be provided with the 3rd valve, utilizing the 3rd valve is that the inlet of second reverse washing filter is connected with the backflush interface.Therefore, can only utilize three valves in the filtering module of compactness, to realize backflush altogether according to the present invention.
A plurality of preferred embodiment of the present invention illustrates in specification, accompanying drawing and dependent claims.
According to first preferred embodiment, first valve has than any big flow of flow in second valve and second valve, wherein, the flow of second valve and the 3rd valve be in particular first valve flow about 5% to about 20%.In this embodiment, the switching that is used for the backflush process will realize by the combination of two kinds of different valves.For filter to be cleaned and inflow entrance are separated, need have the valve of big flow, for example 2000 to 2500 liters/minute the order of magnitude.Yet, for filter is connected with refluxing, valve with less basically flow is favourable, because can open this valve very fast, and produce compression shock therefrom in filter, this compression shock is removed dirt when backflush better from filter.
According to another preferred embodiment, first valve is especially double-acting moushroom valve, and this moushroom valve for example is open from two seal receptacles by spring, and under normal circumstances is placed in the centre position.Second valve and the 3rd valve can be moushroom valves, and they for example have the flow of 200 liters/the number of minutes magnitude.
According to another preferred design, reverse washing filter is erected to be arranged on above the housing, because can make the dirt for the treatment of backflush accumulate in the outlet opening place that is used to wash better in this way.
In addition, the inflow entrance of filter station and flow export design and are arranged to plug-in type jack and casing joint like this, and promptly filter station is series connected.In this way, a plurality of filter stations can be connected in series by simple pegging graft mutually, thereby improve filter capacity.
Description of drawings
Next, only exemplarily present invention is described according to advantageous embodiments and with reference to accompanying drawing.Shown in the figure:
Fig. 1 is the perspective view of filter station;
Fig. 2 is the hydraulic diagram of the filter station of Fig. 1; And
Fig. 3 is the sectional view of the filter station of Fig. 1.
The specific embodiment
Fig. 1 shows the perspective view of the filter station that is used for underground mining, and this filter station has the housing 10 that is designed to filtering module, and first reverse washing filter 12 and second reverse washing filter 14 are set on this housing.First reverse washing filter 12 and second reverse washing filter 14 be erected to be arranged on housing above.The first traveling control valve of reference identification 16 expressions, it can be controlled electrically by plug 18.
Stacked on top of each otherly on housing wall housing 10, be provided with an inflow entrance P alignedly in the left side among Fig. 1
InWith a flow export P
