Junction be located between the first strainer 22 and the second strainer 23 in the height direction.
At runtime, sewage enters the first groove body 3 from water inlet 4 to equipment for separating liquid from solid with drain control unit, with
Being discharged into for sewage, the liquid level in the first groove body 3 be gradually increasing, sewage successively passes through the mistake of the second strainer 23 and the first strainer 22
Filter, finally when liquid rises to water outlet 5, the sewage by removal of impurities processing is flowed out from water outlet 5；In the process, due to miscellaneous
The density of matter pollutant is generally large, can preferential deposition in 3 bottom of the first groove body, only partial impurities can under flow action,
Siltation is in 23 bottom surface of the first strainer 22 and the second strainer upwards.Sewage meeting when the first strainer 22 is blocked, in the first groove body 3
It is discharged by drainage tube 7 in the upper groove body of second groove body 6, when the water level in upper groove body rises to the upper port into water channel 8, with
Drainage tube 7 continue to direct water into upper groove body, sewage can enter lower groove by entering water channel 8, and floating body 11 is made by buoyancy
With, as buoyancy increases, floating body 11 slightly floats, and jacks up plug 9, and then the sewage in upper groove body flows rapidly into lower groove,
Floating body 11 floats rapidly, by vertical bar 12 and pull ring 13 the first strut 14 of lifting and the second strut 25 upwards, and then by baffle
16 lift rapidly, when baffle 16 is put to 20 phase apical grafting of block, no longer move up；Sewage in first groove body 3 quickly on to
Under flow through, rinse out the foreign-matter contamination of the first filter screen and the second filtering sieve bottom siltation, be then discharged into the from outlet 17
In three groove bodies 1, and flowed out from sewage draining exit 2；When drainage tube 7 is no longer discharged into sewage into the second groove body 6, the dirt in the second groove body 6
Water can all be discharged into third groove body 1 by drainpipe 21, and be discharged from sewage draining exit 2, and at the same time, floating body 11 is fallen, 9 weight of plug
New to block water inlet, baffle 16 falls, and closes outlet 17, and then the device for removing dirty impurities in water continues from water inlet
4 water inlets, are discharged after removal of impurities is handled from water outlet 5.
Embodiment 2
As influent load amount increases, lifting pulling force needed for baffle also be will increase, when the top pulling machine structure is limited by space
When, it is necessary to lever assembly is further changed.
A kind of drain control unit keeps the second groove body 6 in embodiment 1, drainage tube 7, enters aquaporin as shown in Fig. 6 ~ 9
8, plug 9, partition 10, floating body 11, vertical bar 12, baffle 16, outlet 17, the first support 18, first support 15, drainpipe
21, second support 24, the second support 26 are constant, only change the combination of lever assembly in top pulling machine structure.The lever assembly is set
Set specific as follows: the link assembly includes intermediate plate 28, and pull ring 13 is fixed in the middle part of 28 top surface of intermediate plate, and intermediate plate 28 is logical
It crosses pull ring 13 to connect with the bottom of vertical bar 12, the front and rear ends of intermediate plate 28 are hinged with connecting plate 29, and former and later two
Connecting plate 29 is symmetrical set about vertical bar 12, and bottom and 16 phase of baffle of connecting plate 29 are abutted against, the bottom of rear side connecting plate 29
Portion is hinged with the first strut 14, and first strut 14 is located at the first support 18 to the front end that upper left side extends to the first strut 14
Top, and the first strut 14 and the top of first support 15 are hinged, and the bottom of front side connecting plate 29 is hinged with the second strut 25,
Second strut 25 is located at the top of the second support 26, and the second strut 25 to the rear end that upper right side extends to the second strut 25
