Abstract
The invention discloses a release assembly of a dissolved air floatation clarifier. The release assembly of the dissolved air floatation clarifier comprises a releaser shell and a release tube, wherein the releaser shell is in a cylinder shape and is internally provided with a cavity; the bottom part of the releaser shell is provided with an air inlet which is connected with the cavity; the vertical section of the cavity is in a ladder-shape, and the width of the upper part of the cavity is less than that of the lower part of the cavity; and two layers of release tubes on different horizontal planes are respectively arranged on the upper part and the lower part of the releaser shell and are respectively connected with the upper part and the lower part of the cavity. Because the release tubes are arranged on the releaser shell in two layers, the bubbles discharged from the release tube are hard to be stacked, the oversized bubbles cannot be generated and the air can be fully utilized; because the vertical section of the cavity is in a ladder-shape and the width of the upper part of the cavity is less than that of the lower part of the cavity, the cavity is narrowed gradually from the bottom to the top and the air entering from the air inlet can be buffered, besides, the air pressure of the whole cavity can be balanced and the air pressure of the air entering into each release tube can be more uniform, and then the aeration is more uniform and the aeration effect is increased.
Description
Technical field
The present invention relates to air floatation machine technical field, is a kind of dissolved gas floatator reliever assembly specifically.
Background technology
Air floatation machine is the common equipment of sewage disposal, reliever is the vitals on air floatation machine, at present, the reliever releasing tube on traditional air floatation machine is in same plane, and release room cavity is straight barrel type, when air release sprays in sewage, gas on same plane easily superposes and causes bubble excessive, is unfavorable for making full use of of air, and the cavity of straight barrel type to assign to the air pressure of each bar releasing tube uneven, and then cause aeration uneven, be difficult to the effect effectively playing aeration.
Summary of the invention
Object of the present invention be a kind of aeration is provided evenly dissolved gas floatator reliever assembly.
To achieve these goals, dissolved gas floatator reliever assembly, comprise reliever housing, releasing tube, described reliever housing is cylindrical, and be provided with cavity therein, described reliever housing bottom is provided with the inlet mouth be communicated with cavity, the vertical section of described cavity is trapezoidal, and the width on cavity top is less than the width of bottom, be respectively arranged with the two-layer releasing tube at different level up and down at described reliever housing, bilevel releasing tube is communicated with the top and the bottom of described cavity respectively.
Owing to adopting above technical scheme, releasing tube divides two-layer being arranged on reliever housing, and the bubble that releasing tube is discharged not easily superposes, and avoids producing excessive bubble, is conducive to making full use of air; The vertical section of cavity is trapezoidal, and the width on cavity top is less than the width of bottom, cavity is narrowed from lower to upper gradually, be convenient to cushion the gas entered from inlet mouth, balance the air pressure of whole cavity, make to enter the gas atmosphere of each bar releasing tube evenly, and then aeration evenly, improve the effect of aeration.
Accompanying drawing explanation
Now the present invention will be further described by reference to the accompanying drawings.
Fig. 1 is plan structure schematic diagram of the present invention.
Fig. 2 is the sectional structure schematic diagram in A-A face of the present invention.
In figure: 1, reliever housing, 2, releasing tube, 3, cavity, 4, inlet mouth.
Embodiment
As shown in Figure 1, 2, dissolved gas floatator reliever assembly, comprise reliever housing 1, releasing tube 2, reliever housing 1 is cylindrical, and is provided with cavity 3 therein, is provided with the inlet mouth 4 be communicated with cavity 3 bottom reliever housing 1, the vertical section of cavity 3 is trapezoidal, and the width on cavity 3 top is less than the width of bottom, be respectively arranged with the two-layer releasing tube 2 at different level at reliever housing about 1, bilevel releasing tube 2 is communicated with the top and the bottom of cavity 3 respectively.
Claims (1)
