Abstract

The invention belongs to the technical field of sewage treatment, and discloses a conical sewage treatment device with an elevation overflowing function. The lower part of a tank body is a circular cone, and the circular cone is welded with an upper-part cylinder. The tank body is made of stainless steel. An overflowing device is arranged in the tank. A water inlet pipe is arranged at the top of the tank body, and a water discharging port is provided at the bottom of the tank. Four annular ventilating pipes uniformly surrounds on the outer side of the circular cone. Air holes are provided on the annular parts. Ends away from the tank body are connected with a blower. Ventilating nozzles are annularly arranged and are embedded on the surface of the circular cone. With the ventilating nozzles, the inner part of the tank body communicates with the outside. Air outlet ends of the ventilating holes are oriented inwards, and have upward inclination angles. Air inlet ends are connected with soft connection pipes. Air holes of the annular ventilating pipes are connected to the air inlet ends through the soft pipes. Annular ventilation is adopted as a ventilation manner, such that ventilation efficiency is improved, and air nozzles are prevented from being blocked. Hand valves are provided on the annular ventilating pipes, such that a ventilation opening degree can be adjusted. With the device, problems such as large land occupation and low aeration efficiency of existing aeration devices are solved. With an elevation overflowing device, floating objects can be removed by overflowing, and sludge discharging can be reduced.

Description

A kind of waste water aeration apparatus of liftable overflow

Technical field

The present invention relates to a kind of cone waste disposal plant of liftable overflow, it belongs to technical field of sewage.

Background technology

Aeration refers to and artificially in biochemical aeration tank, passes into air by suitable equipment, to reach the object of expection.Aeration not only makes liquid-to-air contact oxygenation in pond, and due to agitated liquid, accelerates oxygen in air and shift in liquid, thus complete the object of oxygenation; In addition, aeration prevents pond inner suspension body from sinking in addition, strengthens the object that in pond, organism contacts with dissolved oxygen with microorganism, thus ensures that in pond, microorganism is under the condition having sufficient dissolved oxygen, to oxygenolysis organic in sewage.The quality of aerating apparatus, not only affects biochemical wastewater treatment effect, and directly has influence on Treatment stations occupation of land, investment and working cost.Single for the aerating apparatus form of wastewater treatment at present, commonly aeration at the bottom of pond, aeration efficiency is general, and floor space is large, cleaning mud difficulty.

Summary of the invention

In view of the defect that prior art exists, the object of patent of the present invention is to provide a kind of cone waste disposal plant of liftable overflow, adopts circular pattern to ventilate in water, and ventilate more even, ventilation can regulate with valve; Tuyere not easily blocks; Mud can be discharged by plate, easy to clean; Vertical reactor, floor space is little, with lifting overflow device, not only can overflow floating matter but also can ensure that water outlet can not be mingled with tank body bottom mud.

For achieving the above object, the technology used in the present invention solution is a kind of cone waste disposal plant of liftable overflow, by tank body, water inlet pipe, loop vent pipe, hose connector, ventilation mouths, manually-operated gate, water port and mud discharging mouth form, tank body lower part is cone, be welded to connect with upper cylinder, material is stainless steel; Also overflow device is comprised in tank; Tank body top arranges water inlet pipe, and bottom is water port; Article four, loop vent pipe uniform ring is around in outside cone, and annular section arranges pore, is connected with blower fan away from tank body one end; Ventilation mouths annular array is embedded in conical surface, is communicated with inside and outside tank body, and inwardly and have angle of inclination upwards, air intake is connected with hose connector in the outlet air end direction of ventilation mouths; The pore of loop vent pipe is connected on air intake by hose connector.Described mud discharging mouth installs electronic plate.On described loop vent pipe, be provided with the manually-operated gate of adjustable aperture near blower fan one end.Described loop vent tube annulus divides opens a pore every 20 ~ 30cm.Described overflow device comprises the motor, sleeve pipe, the upflow tube that control lifting; , near tank body bottom, risen by driven by motor upflow tube and declined in the lower end of sleeve pipe, according to the silt depth of floater and tank body bottom, and the height of adjustment upflow tube.

After adopting such scheme, compared with prior art having following beneficial effect is that cone annular aerating apparatus entirety is in vertical reactor, save and take up an area, below adopts cone tank form, is equipped with plate-insertion type valve, when being conducive to clearing up, mud is discharged and is collected, draft type adopts loop vent, strengthens drafting efficiency, and tuyere is not easy blocking, loop vent pipe is equipped with hand valve, can regulate ventilation aperture.Solve the problems such as existing aerating apparatus floor space is large, aeration efficiency is low.Be equipped with lifting overflow device, overflow can fall floating matter and reduce mud to discharge.
