Description
Technical field
The present invention relates to a kind of aperture plate all-in-one, suitable for all kinds of intakes, belongs to mechanical technical field of water treatment equipment.
Background technology
The filtering level of domestic intake filtration system arrangement is mostly two level at present, and its first order is grid, the second level
For filter screen, the water after grid and strainer filtering enters water intake system.Grid is made up of grizzly bar, and wherein grizzly bar is by band steel
It is welded with steel is turned round, usual grizzly bar is equidistantly welded together to form certain time of filtration in the form of longitudinal, and is fixed on
In runner, the gap length between grizzly bar is set according to the requirement of the size and water consumption of removing dirt, between usual grizzly bar is net
It is to intercept suspension or floating object larger in water away from the main function for 50mm~80mm, grid, reusing dirt cleaner will
Dirt is fished for onto ground.Filter screen is typically mounted in runner, mesh be generally 3mm × 3mm, 6.43mm × 6.43mm,
10mm × 10mm etc..Filter screen generally will intercept the less dirts such as small fish in water, shrimp by slewing when in use
Rotate on ground to be removed contamination.
But when summer marine growth breaks out or in water in the more intake environment of dirt, traditional longitudinally fixed formula lattice
Grid are bigger due to grizzly bar gap, it is impossible to fish for less dirt, filtered when dirt flows to the second level by the first level grid
During net, a large amount of less dirts cause the load of filter screen excessive, especially when red tide, green tide, jellyfish, Haiti melon etc. break out,
Filter screen all timely can not clear up dirt, cause the water-head before and after filter screen increasing, finally result in equipment downtime, paralysis
Paralysis, the serious threat safe operation of equipment, a large amount of manpowers cleanings of input are additionally needed, increase the workload of on-site maintenance.
Therefore, one kind is now needed can freely to convert water flowing rate, and can solve the problem that existing equipment according to intake scene dirt situation
Load it is excessive caused by fragile problem and water treatment facilities the problem of drag for dirty scarce capacity.
