Description
Technical field
The utility model is related to underground mine use water filtration art, specially a kind of automatic backwash water filter is fitted
Backwash for the filtering and filter device of using water under mine.
Background technology
Since there are more impurity for underground water, it be easy to cause all kinds of facilities（Such as nozzle, pipeline）Blocking, reduce
The service life of facility, and the impurity in mine water is not disposable, therefore need to improve asking for downhole water supply pipeline removal of impurities
Topic.
Invention content
The utility model provides a kind of automatic backwash water filter to solve the problems, such as that underground is cleaned with water.
The utility model is achieved by the following technical solution：A kind of automatic backwash water filter, including carbon
The front end of steel cylinder, the carbon steel cylinder is water inlet, and rear end is water outlet；The water inlet is equipped with discharge pressure table, institute
It states water outlet and is equipped with discharge pressure table；Cartridge filter is installed, the cartridge filter centre position, which is equipped with, to be turned in the carbon steel cylinder
To valve, connecting spring one end, the spring other end are fixed on the inner wall or carbon of cartridge filter on front side of the spool of the switching valve
On steel cylinder inner wall；Blow-off pipe is connected on the rear end face of the cartridge filter, blow-off pipe is pierced by carbon steel cylinder installation blowdown valve；Institute
The water inlet for stating blow-off pipe is equipped with valve ball, and the valve ball is fixedly connected with traction steel wire, and described traction steel wire one end is fixedly connected
It is fixed on blowdown tube wall in spool rear side, the other end of switching valve.
The utility model main body shell is carbon steel cylinder, and front end is the water inlet for the water for needing to filter, and rear end is after filtering
Water water outlet, the main filtration device in shell is cartridge filter, since the centre position in cartridge filter is provided with and spring
Connected switching valve, therefore cartridge filter is divided into ante-chamber and back cavity by switching valve, backwash is to the anti-of cartridge filter back cavity
It rinses, the valve ball at end-of-the-pipe after cartridge filter is for blocking nozzle, the integral structure structure of valve ball and traction steel wire
At pulling mechanism, switching valve automatic conversion under the active force of water, spring and pulling mechanism opens and closes state, has distinguished
At the process of filtering and blowdown；The discharge pressure table that the discharge pressure table and water outlet of water inlet go out, before observing blowdown
Whether hydraulic pressure afterwards normal, when the reading of two pressure gauges is inconsistent, illustrates that cartridge filter has blocking, need open blowdown valve into
Row blowdown.Specific operation process is：When blowdown valve is opened, increase suddenly with the pressure difference at blowdown valve port in carbon steel cylinder, it is high
Pressure water promotes to the right valve ball, and into blow-off pipe, while valve ball hauls the elastic force that traction steel wire overcomes spring, makes switching valve
For 0 ° of closed state（As shown in Figure 2）, flow forms a cycle around switching valve, by the ante-chamber filter hole stream of cartridge filter
Go out, part flow is flowed into, by blow-off pipe under carbon steel cylinder and the effect of blow-off pipe inside and outside differential pressure by the filter hole of cartridge filter back cavity
Outflow realizes the backwash to cartridge filter back cavity, so that pollutant water is flowed to blowdown valve from blow-off pipe and be discharged；When blowdown valve closes
It closes, blow-off pipe inside and outside differential pressure is zero, and filter restores to normal filtration state, and high pressure water flow no longer acts on valve ball, then valve ball
Pulling force is lost to the spool of switching valve, spring returns to normal, and reopens spool, meanwhile, valve ball is pulled extremely by traction steel wire
At the water inlet pipe mouth of blow-off pipe, it is closed blow-off pipe, the spool of switching valve is in 90 ° of opening states of Fig. 1, and water is filtered through cartridge filter
Afterwards, it is flowed out from water outlet.
Preferably, water inlet is equipped with 10 mesh filter screens；Water outlet is equipped with 140 mesh filter screens, water can be made to exist in this way
Into coarse filtration is carried out when filter, some big impurity are blocked in outside filter, the thin filter screen of water outlet can be with
Fine filtering is carried out, two filter screens, which can remove, to be cleaned.
It is further preferred that above-mentioned two filter screen is made of stainless steel material.
Preferably, the cartridge filter uses stainless steel, and the sieve pore on cartridge filter is 120 mesh.
Preferably, the valve ball uses stainless steel, can be welded to connect in this way with traction steel wire.
The utility model has the advantages that compared with prior art：The device efficiently solves underground feed pipe
The difficult problem of road removal of impurities, while can carry out full-automatic back washing online, need not stop work i.e. capable of washing, the device switching valve by
Spring is controlled, and in blowdown and filter operation, may be implemented auto-steering, reasonable design, ensure that safety in production and by
When produce, ensured the normal use of dustproof facilities.
