Abstract
The utility model discloses a defoaming device is used for aeration tank defoaming, is by motor, shaft coupling, main shaft, frame, bearing frame, upper bearing, lower bearing, upper bearing lid, lower bearing lid, axle sleeve, seal box gland, sealing member, baffle, impeller, defoaming case, inhale the foam cover and constitute, when the motor drives the high-speed rotation of impeller, forms certain negative pressure, and aeration tank foam on the surface is inhaled in the defoaming incasement, eliminates the foam. The utility model adopts a mechanical mode to eliminate foam, and has the characteristics of water conservation, reliable foam eliminating effect, convenient use and no secondary pollution.
Description
The utility model relates to a kind of defoamer of eliminating the aeration tank surfactant foam in sewage disposal process that is applicable to, belongs to the environmental protection equipment field.
Eliminate the aeration tank surfactant foam at present, generally adopt the water spray or add chemical defoamer.Water spray froth breaking need be installed the bath pipe network, consume big water gaging.Then cost is higher to add the chemical defoamer froth breaking, and it is complicated that dosage calculates control, when dosage is big, also can cause secondary pollution.
The purpose of this utility model is the problem at above-mentioned existence, the defoamer that propose a kind of water saving, the foam that disappears is reliable for effect, easy to use, does not have secondary pollution.
The purpose of this utility model is to realize like this, defoamer of the present utility model is by motor, shaft coupling, main shaft, frame, bearing block, upper bearing (metal), lower bearing, upper ball cover, lower ball cover, axle sleeve, seal box, the seal box gland, seal, baffle plate, impeller, defoaming box, inhaling the foam cover constitutes, be connected with shaft coupling between motor and the main shaft, motor is fixedly connected on the top of frame, bearing block is fixed on the support of frame, two ends up and down at bearing block have upper bearing (metal) respectively, upper ball cover, lower bearing and lower ball cover, between upper ball cover and lower ball cover and the bearing block is to fixedly connected, axle sleeve is enclosed within the outside of main shaft, between upper bearing (metal) and the lower bearing, the bottom of frame is connected with defoaming box, be separated with baffle plate between frame and the defoaming box, there is seal box the centre of baffle plate, seal in the seal box is fixed with the seal box gland, suction foam cover is installed in the bottom of defoaming box, and impeller is installed in the lower end of main shaft.Above-mentioned frame can be tapered, and two layers of support are arranged together in frame; Above-mentioned defoaming box can be a spiral shell shape housing.
Defoamer of the present utility model rotates at a high speed with the motor impeller, inhaling foam cover annex formation certain negative pressure, under atmospheric effect, the lip-deep foam in aeration tank is inhaled in the defoaming box, the double action that blade is sheared and centrifugal force pushes by impeller, the foam fragmentation becomes drop, returns the aeration tank through leakage fluid dram.The utility model is owing to adopt mechanical system to eliminate foam, the characteristics that therefore, have water saving, the foam that disappears is reliable for effect, easy to use, do not have secondary pollution.
