Description
Technical field:
The present invention relates to a kind of filter mechanisms of the large-scale pipeline filter device for water delivery supervisor's net.
Background technology:
It is totally-enclosed to be responsible for online large-scale pipeline although in water delivery, but is easy to allow one in being laid with pipeline and maintenance process
The building wastes such as a little brick, waddys enter inside pipe network, in the process of construction of pumping plant, can also be inevitably generated
Rubbish enters supervisor's net, and the flow velocity direction of supervisor's net clear water during long-term use changes or slack-off also will produce one
A little sediments, these objects to the shock of tube body, be easy to cause damage under the action of flow to pipeline and valve.It is existing
Piping filter is y-type filter, and bore is small, can not be suitable for the big water delivery of bore and be responsible for net, shell uses square shell, nothing
Method by hydraulic pressure it is evenly dispersed fall, clear up rubbish impurity when directly from the lower part of filter will store impurity device take out, for
Large-scale water delivery supervisor's net filtration gets off the larger rubbish impurity of weight, and the device for taking out storage rubbish is extremely difficult, clears up rubbish
It is taken time and effort very much when impurity, influences working efficiency.
To solve the above problems, patent No. 201620299108.X proposes a kind of large-scale pipeline filter, and it is simple in structure, it can
Quick separating water and rubbish, good filtration effect reduce the damage to pipeline and valve, but the patent has the disadvantage that:1、
In the case where flow velocity is larger, water quickly passes through from filter screen, poor filtration effect;2, the rubbish of large volume will be filtered net in water
Barrier is fallen on bottom plate, but the meeting of the impurity of water small particles is flowed out across filter screen from outlet portion, and filter effect is influenced,
Some meetings are left in the filter hole of filter screen, for a long time, it is easy to be blocked to filter screen, be cleared up the periodicity of filter screen
It is short, it is time-consuming and laborious;3, filter screen is an integral structure with external support component, is unfavorable for dismantling, and cleaning is inconvenient.Therefore, such as
Fruit provides a kind of filter mechanism for being convenient to clean, extending cleaning cycle, the large-scale pipeline filter device for improving filter effect, is bound to
The market demand can be responded.
