Utility model content

In view of the deficienciess of the prior art, there is each aerator the utility model lies in that providing a kind of aeration tank Agitating plate only controlled by rotary electric machine, reduce the function of aeration tank manufacturing cost.

To achieve the above object, the utility model provides following technical solution: a kind of aeration tank, including pond body, described Multiple aerators and driving mechanism are equipped in pond body, the driving mechanism includes the bracket for being fixed on pond body upper end, the branch Frame epipleural fan be fixed with rotary electric machine, shaft is fixed on the rotary electric machine, be fixed in the shaft multiple positions with The one-to-one horizontal bevel gear of aerator, the aerator include the support shaft with the rotation connection of pond body left and right sidewall, The support shaft is fixed with the vertical bevel gear engaged with horizontal bevel gear, the circumferential side wall of the shaft close to one end of shaft On be fixed with multiple agitating plates.

By using above-mentioned technical proposal, when the sewage of pond body adds complete, the aerator part of the top is located at dirt Water inner part is located in air, drives each horizontal bevel gear in shaft to rotate by rotary electric machine, then drives horizontal cone Gear rotation is realizing the aeration to sewage, and pool bottom is in so that the agitating shaft in each support shaft be driven to rotate The sewage in portion, which can constantly rise, to be aerated, so that dirty water and air is more fully mixed, while a rotary electric machine is used only The agitating plate rotation being just able to drive in each aerator, reduces the manufacturing cost of aeration tank.

The utility model is further arranged to: the pond body inner wall is equipped with sliding slot, is removably connected in the sliding slot Slide plate, the support shaft and slide plate are rotatablely connected, and the agitating plate is detachably connected with support shaft.

By using above-mentioned technical proposal, agitating plate is chronically in sewage, is easily contaminated and is damaged, when needing to tie up When protecting agitating plate, slide plate is separated with sliding slot and slide plate is thought to the horizontal bevel gear when Slideslip far from shaft and is bored vertically After gear separation, then the aerator on slide plate and slide plate is taken out upwards, then separate agitating plate with support shaft, to agitating plate It is separately maintained.

The utility model is further arranged to: the structure of the sliding slot and slide plate being detachably connected are as follows: the slide plate Upper end is fixed with movable plate, and the movable plate is fixedly connected by bolt with pond body upper side wall；The agitating plate and support shaft can The structure of dismantling connection are as follows: the agitating plate includes the mounting plate being bolted with support shaft and fixes on a mounting board Rotating plate.

By using above-mentioned technical proposal, when needing to safeguard agitating plate, first by the disassembling bolts on movable plate, then Xiang Yuan Side moving slide board from shaft, takes out slide plate then up, then by the disassembling bolts on mounting plate, so that agitating plate It separates with support shaft, agitating plate is separately maintained convenient for people.

The utility model is further arranged to: the slide plate is fixed with multiple lifting plates far from the side of shaft.

By using above-mentioned technical proposal, people when slide plate is taken out from sliding slot upwards, can by lifting plate come to Upper pulling slide plate, so that slide plate taking-up is more convenient.

The utility model is further arranged to: the upper surface of the lifting plate offers kerve.

By using above-mentioned technical proposal, people can hold lift block by kerve to move cunning when pulling lifting plate Plate, so that people are more convenient come moving slide board by lifting plate.

The utility model is further arranged to: the slide plate is equipped with multiple crushing blocks, the extruding far from the side of shaft Block is driven by being fixed on the extruding cylinder on the outside of pond body.

First slide plate is put into sliding slot when installing slide plate by using above-mentioned technical proposal, then by squeezing cylinder The side for driving crushing block to close shaft is mobile, so that slide plate is connected to side of the sliding slot close to shaft under the action of crushing block On wall, then movable plate is fixed by bolt and pond body upper side wall.Make slide plate be not easy to shake under the action of crushing block, makes Vertical bevel gear in each shaft can stablize and engage with horizontal bevel gear, improve the stability of transmission, while slide plate energy Enough so that sewage is not easy to flow into slot again by squeezing the gap outflow between cylinder piston rod and pond body.

The utility model is further arranged to: the slide plate and being set close to pond body inner wall side there are two sealing strip.

By using above-mentioned technical proposal, when slide plate, which is squeezed block, to be squeezed, slide plate is close by sealing strip and sliding slot The side wall of shaft abuts, and the leakproofness of slide plate is further increased, so that sewage is not easily accessible in sliding slot.

The utility model is further arranged to: the pool bottom is fixed with support column, and the upper end of the support column is cone Shape, the lower end of the shaft are equipped with the link slot of taper, and the support column insertion link slot is interior and abuts with the upper end of link slot.

By using above-mentioned technical proposal, support column can be supported on the lower end of shaft and not influence shaft rotation, So that shaft is not easy to shake when rotating, enable horizontal bevel gear and vertical bevel gear stable engagement, improves the stabilization of transmission Property.

In conclusion the utility model has the following beneficial effects:

It drives each horizontal bevel gear to rotate simultaneously by a rotary electric machine, vertical bevel gear is then driven to rotate, And then the agitating plate in each support shaft is driven to rotate, realize the aeration to sewage, and reduce the manufacturing cost of aeration tank.
