Abstract
The utility model discloses a kind of cloth weir board of the water inlet for deep-bed filter or dark bed Denitrification filter system, namely profile of tooth one-level influent weir and arc secondary influent weir are installed on concrete influent weir.Deep-bed filter and dark bed denitrification filter pool are generally thin-and-long structure, both sides, filter tank inlet flume length is maximum reaches more than 30 meters, the long water of water distribution is very long, coagulation earth bank or one pole weir plate, be difficult to realize water distribution uniformity, when flooding velocity is less, uniformity of water distribution is poorer, requires very high to the levelness of coagulation earth bank and one pole weir plate and setting accuracy.Two-stage cloth weir board, by passing through arc weir plate secondary water distribution again after profile of tooth weir plate one time water, realizes water distribution even, reduces the requirement of weir plate setting accuracy simultaneously.
Description
Technical field
The utility model is mainly used in sewage disposal deep-bed filter and dark bed denitrification filter pool, is specially both sides, filter tank inlet flume coagulation earth bank and installs profile of tooth weir plate and arc weir plate, strengthens the homogeneity of filter tank water inlet water distribution.
Background technology
Conventional filter tank inlet flume arranges concrete influent weir, and adjustment coagulation earth bank surface elevation level, pending water enters inlet flume, climbs over concrete influent weir water distribution.Concrete water distribution weir requirement for horizontality is higher, and cloth mill weir length can not be long, and the change of flooding velocity all will affect the homogeneity of filter tank water inlet water distribution.
Deep-bed filter or dark bed denitrification filter pool pool-type structure are generally thin-and-long, filter tank long-width ratio is greater than 5 usually, filter tank length is the longest reaches more than 30 meters, sewage climbs over both sides, filter tank by top, filter tank and enters filter tank process along the influent weir that filter tank length direction is arranged, cloth mill weir length is the longest is also greater than 30 meters, and the structure design of cloth mill weir and setting accuracy directly affect the homogeneity of water inlet water distribution.The one-level arc water inlet weir plate that deep-bed filter and dark bed denitrification filter pool cloth mill weir have concrete cloth mill weir and install on concrete influent weir, influent weir upper limb level, can realize water distribution uniformity under particular flow rate.Concrete influent weir and one-level arc weir plate exist certain not enough, and as requirement for horizontality is high, setting accuracy requires high, the defects such as flooding velocity changes greatly, uniformity of water distribution reduction.
Summary of the invention
Deep-bed filter or dark bed denitrification filter pool pool-type structure are thin-and-long, concrete inlet flume is arranged in both sides, filter tank along filter tank length direction, inlet flume and concrete water inlet cloth mill weir length are slightly less than filter tank length, being inside concrete cloth mill weir inside inlet flume, is outside concrete cloth mill weir outside inlet flume.
Profile of tooth cloth weir board is installed inside concrete cloth mill weir, realizes filter tank and to intake a time water.Profile of tooth water inlet weir plate " V " shape water inlet gap, is applicable to the requirement of different flow water inlet water distribution.
Cover above concrete cloth mill weir and install arc water inlet weir plate, cambered surface height is less, intakes to be distributed again rapidly by arc weir plate by profile of tooth one-level cloth mill weir, realizes water inlet two time water.
The utility model has following beneficial effect:
1. profile of tooth one-level cloth weir board is suitable for different flow water inlet water distribution uniformity.
2. reduce concrete influent weir requirement for horizontality.
3. profile of tooth cloth weir board and arc cloth weir board setting accuracy require to reduce.

Embodiment
Inside concrete influent weir 5, profile of tooth cloth weir board 4 is installed in inlet flume 2 in deep-bed filter or deeply bed denitrification filter pool 1, profile of tooth cloth weir board 4, to intake water zero position height higher than concrete influent weir 5 top and arc weir plate 3 bottom profile of tooth cloth weir board 4 " V " shape cloth water space, notched plate 7 needs circular hole 8 hollow out, prevent air water back washing drainage procedure, suspended substance is piled up outside dentation weir plate 4.Profile of tooth cloth weir board 4 is fixed on inside concrete influent weir 5 by stainless steel expansion bolt.
Arc weir plate 3 arc vertex mounting height is a little more than bottom profile of tooth cloth weir board 4 " V " shape gap, arc weir plate 3 covers concrete influent weir 5 top, intake initial line and one-level profile of tooth cloth mill weir 4 of arc weir plate 3 is abutted against, regulate curved weir plate level, arc weir plate is fixed at concrete influent weir 5 top and outside by stainless steel setscrew, lower concrete bed course 6, and levelling.
Profile of tooth weir plate 4 and arc weir plate 3 two-stage weir plate and installation accessories material adopt 304 or 316 stainless steels, and profile of tooth weir plate 4 stainless steel setscrew open holes is set to waist shaped hole 9, can up-down adjustment weir plate mounting height; Arc weir plate lateral expansion screw open holes 10 is set to waist shaped hole, can up-down adjustment weir plate mounting height, and top mounting holes is circular hole 11, and two-stage weir plate installation length is equal with concrete influent weir length.
