Description
Technical field
The present invention relates to a kind of backwash high pressure filtering device that is used for comprehensive mining hydraulic bracket hydraulic system under the coal mine, refer in particular to a kind of backwash high pressure filtering device.
Technical background
The hydraulic system that comprehensive mining hydraulic bracket adopts under the coal mine, be in down-hole coal ash high pollution situation, hydraulic system source emulsion tank very easily is subjected to the coal ash powder dust pollution, cause heel and toe wear or damage for each seal of hydraulic system, cause hydraulic system unit time internal fault to take place frequently, cause very big harm for the fully-mechanized mining equipment operate as normal.Existing coal production enterprise, hydraulic medium pollution control engineering technological means mainly concentrates on auxilliary establishing system miniaturization filtration and washing engineering device on each function valve member assembly of subsystem application section, and this resolution system is used section pollution control problem.Because Aided Design engineering device is limited by function valve member volume conditions, can not assist and join big traffic engineering device, the pollution problem of hydraulic pressure total system can not be solved in control, certainly will cause whole hydraulic system internal contamination substrate concentration more and more higher, cause subsystem function valve member responsibilities function and dual the increasing the weight of of hydraulic medium filtering function live load.Because the low capacity filter is faced the more and more higher hydraulic medium of pollution concentration directly, the normal mechanical function must be subjected to grievous injury, very easily causes various seal heel and toe wears or damage, influences system's operate as normal efficient.
Summary of the invention
The object of the present invention is to provide a kind of backwash high pressure filtering station, carrying out initial one-level working media from the hydraulic system source filters, improve the inherent cleannes of hydraulic work system medium emulsion from source control, for hydraulic system provides comparatively desirable cleaning medium emulsion, alleviate each element filters medium live load of subsystem, further carry the job stability of high comprehensive mining hydraulic system, reduce each class component sealing maintenance works, improve unit labor productivity, reduce system failure incidence, prolong the application life of each class component of hydraulic system.
For achieving the above object, the invention takes solution to be: a kind of backwash high pressure filtering station, the backwash module is housed on the assembly casing, the valve body of backwash module has input channel, output channel, the backwash passage, filtration chamber, left side inlet and right filtration chamber inlet, valve seat is placed in backwash passage and entrance, left filtration chamber, valve pad and steel ball, steel ball and left operating mechanism are supporting, fix left backwash switch knob on the operating mechanism of a left side, valve seat is placed in backwash passage and entrance, right filtration chamber, valve pad and steel ball, steel ball and right operating mechanism are supporting, fix right backwash switch knob on the right operating mechanism, have L shaped passage in the steel ball, filtration chamber, left side inlet connects left filtration chamber, right filtration chamber inlet connects right filtration chamber, backwash passage left end connects left filtration chamber's backwash outlet connection, backwash passage right-hand member connects right filtration chamber's backwash outlet connection, input channel connects the input port joint, output channel connects the delivery outlet joint, filtration chamber's backwash outlet connection in a left side is connected and preposition one way valve by pipeline with right filtration chamber's backwash outlet connection, the spherical stop valve of the preposition input of input port joint, the spherical stop valve of the rearmounted output of delivery outlet joint.
The duty of filtration chamber is to control each other dielectric fluid flow path direction by backwash switch knob and operating mechanism.In normal operation, liquid medium is by the filtration chamber that flows through of L passage in the steel ball in the valve body, from output channel output, for the hydraulic system applications section provides the working media liquid of cleaning through primary filter.Because during flow of high-pressure fluid process filter chamber, mechanical admixture in the liquid is with filtration resistance, growth along with service time, mechanical admixture is more and more in the filtration chamber, the pressure at two ends difference of filter element is increasing in the filtration chamber, when pressure reduction reaches certain numerical value, then needs to carry out the backwash working programme, otherwise will influence system works efficient, then cause failure accident when serious.Manually carry out the mutual backwash of filtration chamber by switch knob.Drive the operating mechanism that is controlled in the valve body by the switch switch knob.Rotate an operating mechanism input side will be closed to the inlet of next filtration chamber, meanwhile, the backwash of pent filtration chamber is activated.The medium that need purify flows through the filtration chamber in this work fully in backwash process.The medium that has been filtered of a part, through outlet side flow to open etc. in the filtration chamber subject to backwash, flow through round about and the impurity of the inside taken out of by the backwash outlet.The backwash of two filtration chambers often hockets, and that is to say on-streamly ceaselessly to clean two filtration chambers.
This flushing high pressure filtering station, carrying out initial one-level working media from the hydraulic system source filters, improve the inherent cleannes of hydraulic work system medium emulsion from source control, for hydraulic system provides comparatively desirable cleaning medium emulsion, alleviate each element filters medium live load of subsystem, further carry the job stability of high comprehensive mining hydraulic system, reduce each class component sealing maintenance works, improve unit labor productivity, reduce system failure incidence, prolong the application life of each class component of hydraulic system.
