The mud system falls in the advection sand setting that removes slag
Technical field
The present invention relates to environmental protection equipment, be specifically related to the advection sand setting that removes slag and fall the mud system.
Background technology
The general employing steel wire rope type grid sewage-removing machine of existing sanitary sewage purifies, can remove a large amount of larger particles and the suspended substance that is difficult to precipitate, has plenty of the material that belongs to bio-refractory, have plenty of that belong to can biochemical degradation but become the macromolecular mass structure, can't to mud with and desilting administer.
Summary of the invention
The purpose of this invention is to provide the advection sand setting that removes slag and fall the mud system, mud falls in the sand setting that can remove slag.
Advection remove slag sand setting fall the mud system comprise bypass channel, be located at movable bifurcation gate in the middle of the bypass channel, be located at the bypass channel inboard water leg, be located at the water leg upper end the advection grid, be located at the advection grid be provided with clearing apparatus, be located at advection grid inboard the spiral discharging groove, be located at screw shaft in the spiral discharging groove, be located at the settling bath on water leg right side.
Described clearing apparatus comprises two belt pulleys of being located at advection grid top, be sheathed on belt on two belt pulleys, be distributed in the hairbrush on the belt outside surface, described belt pulley is by electric motor driving, and described hairbrush can clean the larger particles and the suspended substance that is difficult to precipitate on the advection grid surface.
Described settling bath is made as first settling bath successively, second settling bath, the 3rd settling bath.
Owing to be provided with said structure, the suspended substance that this system not only can handle larger particles and be difficult to precipitate, also can to mud with and desilting administer, and be convenient to cleaning.
Description of drawings
Fig. 1 falls the structural representation of mud system for the advection of the present invention sand setting that removes slag.
Fig. 2 is the side-view of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, advection remove slag sand setting fall the mud system comprise bypass channel 1, be located at movable bifurcation gate 2 in the middle of the bypass channel 1, be located at bypass channel 1 inboard water leg 3, be located at water leg 3 upper ends advection grid 4, be located at advection grid 4 be provided with clearing apparatus 5, be located at advection grid 4 inboards spiral discharging groove 6, be located at screw shaft 61 in the spiral discharging groove 6, be located at the settling bath on water leg 3 right sides.Owing to be provided with movable bifurcation gate 2; can under non-stop-machine situation, carry out cleaning maintenance to system; described clearing apparatus comprises two belt pulleys 51 of being located at advection grid top, be sheathed on belt 52 on two belt pulleys 51, be distributed in the hairbrush 53 on belt 52 outside surfaces; described belt pulley 51 is by electric motor driving, the suspended substance that described hairbrush 53 can clean advection grid 4 lip-deep larger particles and be difficult to precipitate.Described settling bath 7 is made as first settling bath, 71, the second settling baths 72, the 3rd settling bath 73 successively.During work, sewage flows on the advection grid by bypass channel, the larger particles that contains in the sewage and the suspended substance that is difficult to precipitate are filtered on the advection grid, sent in the spiral discharging groove by clearing apparatus, silt then enters water leg with sewage, and sewage enters settling bath again and carries out fractionation precipitation to remove silt.
