Description
Technical field
Technical field of sewage treatment equipment is the utility model is related to, more particularly to a kind of overfall quick opening structure.
Background technology
In the sewage treatment plant of large size city, the former design of coarse rack platform upper leads directly to elevator pump using overfall and cheated.Pipe
When net water level is higher than coarse rack, water will cover coarse rack platform, and a large amount of current flow into elevator pump by overfall and cheated, formed larger
Suction.Near coarse rack grabs bucket close overfall, the common of grid is directly impacted in this suction and sewage network reclaimed water
Under effect, grab bucket is easily punched into overfall, make grab bucket can not normal work, and easily damage is grabbed bucket.If pipe network
Water level is maintained at high-order for a long time, can not intercept the slag thing to get off capture grid using grab bucket at all, cause grid to block up
Plug is serious, grid water amount rapid decrease.The sewage that substantial quantities of entrained Large Slag thing is directly entered pump hole by overfall, causes
Elevator pump damage is frequent.
In order to ensure mobile grab bucket normal work, overfall needs a kind of valve system for blocking sewage and flowing into pump hole.Lock
