Abstract
The utility model discloses a capping device for an aerated grit chamber and a horizontal-flow sedimentation tank. The capping device comprises a fixed cover plate and flexible inflation bags on the two sides of a sand/mud absorption pipe; after the flexible inflation bags on the two sides are inflated, the edges are connected and sealed with the fixed cover plate; the flexible inflation bags expand after being filled with pressure gas; and the bags on the two sides extrude each other to realize sealing. Since the surfaces of the flexible inflation bags easily deform elastically, the movement of the mud absorption pipe between the flexible inflation bags on the two sides can be well guaranteed so as to maintain the tightness of the capping device. The device disclosed by the utility model does not influence the movement of the sand/mud absorption machine, has good sealing performance and low manufacturing cost, is convenient to construct, and minimizes the gas leakage of the tank capping space when the sand/mud absorption machine moves back and forth.
Description
Technical field
The utility model relates to the capping device of a kind of aerated grit chamber and rectangular sedimentation tank, belongs to environmental technology field.
Background technology
Mostly the aerated grit chamber and the rectangular sedimentation tank of existing sewage treatment plant are unenclosed construction, generally all do not add a cover, and cause distributing of foul gas and VOC, cause the deterioration of working environment and surrounding enviroment.Because aerated grit chamber and rectangular sedimentation tank be all supporting sand sucker and the suction dredge that moves around arranged; Sand sucker and suction dredge are provided with sand suction pipe and dredging tube and reach and extract sand setting at the bottom of the pond and heavy mud is discharged outside the pond; If in the body of pond, add a cover; Because sand suction pipe and dredging tube move around, and the monoblock type cover plate can't be installed.If adopt integral body to add a cover in sand sucker and suction dredge be enclosed in, because sand sucker is high with suction dredge action required space, so integral body adds a cover the also corresponding increase in space, causes that material cost is too high, the sealing collection gas compartment is excessive, causes the tolerance increasing of deodorizing.The integral body mode of adding a cover makes sand sucker and suction dredge be enclosed in the lid to contact with etchant gas, can cause equipment corrosion in addition, reduction equipment life and to operation of equipment, overhaul and also to have inconvenience.
Summary of the invention
The aerated grit chamber that the purpose of the utility model is to provide a kind of and does not hinder that the sand sucker suction dredge moves, good seal performance, easy construction, cost are low and the capping device of rectangular sedimentation tank.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is: the capping device of a kind of aerated grit chamber and rectangular sedimentation tank is made up of fixed cover plate and flexible air bag; Fixed cover plate is fixed on the pool wall on aerated grit chamber and the rectangular sedimentation tank; Materials such as the sheet material of fixed cover plate materials employing light weight corrosion resistant such as fiberglass plane skylight, sunlight board, force-bearing plate, corrosion resistant plate, aluminium alloy plate; The both sides, dredging tube zone of action of suction dredge are provided with flexible air bag, the sealing that links to each other with fixed cover plate of its edge, flexible air bag inflation back, and the inner gassy of flexible air bag, the air bag of the both sides, back of expanding is mutual to be pushed and seals.Because air bag is easy to assurance dredging tube smooth and easy moving between air bag that strain can be good, guarantees the seal of capping device simultaneously.
Flexible air bag has inflation inlet, adopts the blower fan continuous charge; Be provided with the inflation check valve in the inflation inlet, can prevent gas leak after being full of gas.
The advantage of the aerated grit chamber of the utility model and the capping device of rectangular sedimentation tank is not hinder the moving of sand sucker suction dredge, good seal performance, easy construction, cheap.
Description of drawings
Fig. 1 is the structural representation of capping device of aerated grit chamber and the rectangular sedimentation tank of the utility model;
1 is aerated grit chamber and rectangular sedimentation tank pond body among the figure; 2 is fixed cover plate; 3 is suction dredge; 4 is dredging tube; 5 is flexible air bag.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the aerated grit chamber of the utility model and the capping device of rectangular sedimentation tank are elaborated.
As shown in Figure 1, in aerated grit chamber and rectangular sedimentation tank body 1, do not have the dredging tube zone of moving fixed cover plate 2 is set, fixed cover plate 2 is fixed on the pool wall, materials such as the sheet material of employing light weight corrosion resistant such as fiberglass plane skylight, sunlight board, force-bearing plate; At suction dredge 3 and both sides, attached dredging tube 4 zone of action flexible air bag 5 is installed, its edge, flexible air bag 5 inflation back is connected with fixed cover plate 2 and seals.Flexible air bag 5 has inflation inlet, is provided with the inflation check valve in the inflation inlet, and flexible air bag 5 is charged into air, is in contact with one another after the both sides air bag expands and airtight.Flexible air bag adopts flexible material, and surface, inflation back can be with external force deformation, does not therefore hinder moving around of dredging tube 4 on the suction dredge 3.
The aerated grit chamber of the utility model and the capping device of rectangular sedimentation tank have and do not hinder the moving of sand sucker suction dredge, good seal performance, easy construction, advantage such as cheap.
