Description
Technical field
The utility model belongs to hydraulic pressure of the colliery system, and in particular to a kind of fully-mechanized mining working hydraulic system filter.
Background technology
Emulsion is the hydraulic medium that China's coal-mine hydraulic support mainly uses, and the pollution of emulsion or cleanliness factor do not reach
Mark, pumping station system abrasion can be not only increased, greatly shorten the service life of pumping plant, can also cause blocking, the damage of support valve group,
Increase fault rate, the safe valve protection of hydraulic system opens insensitive, hydraulic packing parts damages etc..According to statistics, in hydraulic system
It is as caused by polluting hydraulic medium to have 70% in failure.
In the fully-mechanized mining working emulsification pump course of work, tiny iron is formd because liquid outlet valve element constantly hits tube wall
Bits, these impurity can enter in working surface hydraulic support along with high-pressure rubber pipe internal emulsification liquid, influence the normal use of support, and
And sometimes because of blocking and caused by high pressure pipe explosion, influence normally to produce.The automatic high pressure recoil that work on hand face has been installed
Though cleaning device can be filtered compared with small particle impurity, easily block, filter effect is not ideal enough, and reliability is not high.
Then, there is research staff to consider from source, the material of valve element and pipeline is improved, reduce or even keep away to reach
Exempt from effect caused by tiny iron filings, such as abrasion-proof corrosion-proof erosion resisting coating is applied to valve element and inner-walls of duct, although effect is more satisfactory,
It is not economical and practical enough but cost is too high.
The content of the invention
The purpose of this utility model is to solve existing automatic high pressure back purge system filter effect not ideal enough, reliability
The problem of not high, and provide a kind of fully-mechanized mining working hydraulic system filter.
In order to complete above-mentioned purpose, the technical solution of the utility model is：
Fully-mechanized mining working hydraulic system filter, including by pipeline be connected respectively with emulsification pump and hydraulic support from
Dynamic high-pressure backwash filter, it is characterized in that：Also include manual recoil cleaning device, the manual recoil cleaning device is by cylinder
Formula filter, tee pipe fitting and two stop valve compositions, one end and the automatic high pressure backwash filter of the cartridge filter
It is connected, the other end is connected with one of opening of tee pipe fitting horizontal direction, another opening of tee pipe fitting horizontal direction
A stop valve is connected, the stop valve is connected with emulsification pump, and the opening of tee pipe fitting vertical direction connects another stop valve.
Further, multigroup manual backwashing dress is additionally provided between the automatic high pressure backwash filter and emulsification pump
Put.
Further, multigroup manual recoil cleaning device is in series or in parallel in automatic high pressure backwash filter and breast
Between change pump.
Compared with prior art, the utility model has the advantage of：
1st, cartridge filter is set between automatic high pressure backwash filter and emulsification pump, can be recoiled in automatic high pressure
One of coarse filtration is first carried out before washing filter to emulsion, improves automatic high pressure backwash filter and is blocked by big particle diameter impurity
Situation.
2nd, tee pipe fitting is connected in the arrival end of cartridge filter, cut-off is set in two other opening of tee pipe fitting
Valve, it can close the stop valve of vertical direction by opening horizontal direction stop valve, be easy to working surface hydraulic support, emulsification
Pump and rinsed away in time with the impurity in emulsion box.
3rd, multigroup back-flushing filtering device is added between guarantor's automatic high pressure backwash filter and emulsification pump, one can be entered
Step enhancing filter effect, ensures hydraulic system highly pressurised liquid purity, reduces the loss of working face hydraulic test, eliminate because of breast
Change equipment fault caused by impurity in liquid, effect is preferable, and reliability is high.
