Description
Technical field
The utility model relates to the backwash filter technical field, relates to a kind of back-flushing filtering device more specifically.
Background technology
Since the reform and opening-up, China's industry has obtained great development, and simultaneously, industrial expansion has driven constantly bringing forth new ideas of China's field of mechanical technique and developed.For example, the mechanization in large-scale colliery, automation have become the inexorable trend of era development, and hydraulic system plays a part very important in large-scale coal mine machinery.
Hydraulic medium need have higher degree of purity in hydraulic system, can guarantee that hydraulic system can operate as normal.In the prior art, adopt backwash filter to carry out the purification of hydraulic medium usually.
Be applied to the backwash filter in the hydraulic system; Be that a kind of filter screen that utilizes is directly tackled the impurity in the hydraulic medium; Remove hydraulic medium suspension, particle, reduce turbidity, purify water; Generations such as minimizing system dirt, bacterium algae, corrosion are with the precision equipment of scavenging solution piezodielectric and other equipment operate as normal of protection system.
Backwash filter is provided with filter net device, and hydraulic medium is flowed through behind the filter net device, and the impurity that is mingled with in it is tackled by filter screen.Filter screen will inevitably adhere to more impurity on it after long-time the use, and then the fluency when influencing hydraulic medium and flowing through filter screen.The backwash filter net is provided with counter-flushing pipeline, and it can will be discharged by sewage draining exit through adverse current attached to the impurity of screen surface under the situation of not dismantling filter screen.
Yet, backwash filter of the prior art, the impurity that invests on the filter screen is more firm, only can't the impurity on the filter screen be rinsed well through back flushing.Must use along with long-time, the impurity on the filter core can be cumulative, and screen pack still can stop up.As everyone knows, the filter screen dismounting in the backwash filter is difficulty, the especially hydraulic system of coal mine machinery relatively, often is in the mine work of inclement condition, for the plant maintenance personnel, changes backwash filter net difficulty more.
Clean halfway problem in order to overcome back-flushing filtering device, have a kind of back-flushing filtering device in the prior art.Please refer to Fig. 1, Fig. 1 is a back-flushing filtering device sectional structure sketch map in the prior art.
