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 artificially pass into air by suitable equipment in biochemical aeration tank, to reach the purpose of expection.Aeration not only makes in the pond liquid-to-air contact oxygenation, and because agitated liquid, has accelerated that oxygen shifts in liquid in the air, thereby finishes the purpose of oxygenation; In addition, aeration prevents that in addition pond inner suspension body from sinking, and strengthen the purpose that organism and microorganism contact with dissolved oxygen in the pond, thereby in the assurance pond there is being under the condition of sufficient dissolved oxygen microorganism, to organic oxygenolysis in the sewage.The quality of aerating apparatus not only affects the sewage Biochemical Treatment, and directly has influence on a processing occupation of land, investment and working cost.The aerating apparatus form that is used at present wastewater treatment is single, aeration at the bottom of the pond commonly, and aeration efficient is general, and floor space is large, cleaning mud difficulty.

Summary of the invention

In view of the defective that prior art exists, the purpose of patent of the present invention provides a kind of cone waste disposal plant of liftable overflow, adopts circular pattern to ventilate in water, and it is more even to ventilate, and ventilation can be regulated with valve; Tuyere is difficult for stopping up; Mud can be discharged by plate, and is easy to clean; Vertical reactor, floor space is little, with the lifting overflow device, not only can overflow floating matter but also can guarantee 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 comprise overflow device in the tank; The tank body top arranges water inlet pipe, and the bottom is water port; Article four, loop vent pipe uniform ring is around in the cone outside, and annular section arranges pore, links to each other with blower fan away from tank body one end; The ventilation mouths annular array is embedded in the cone surface, is communicated with inside and outside the tank body, and the outlet air end direction of ventilation mouths is inside and angle of inclination is upwards arranged, and air intake links to each other with hose connector; The pore of loop vent pipe is connected on the air intake by hose connector.Electronic plate is installed on the described mud discharging mouth.On the described loop vent pipe, be provided with the manually-operated gate that to regulate aperture near blower fan one end.Described loop vent pipe annular section is opened a pore every 20 ~ 30cm.Described overflow device comprises motor, sleeve pipe, the upflow tube of controlling lifting; Being risen and descended by the driven by motor upflow tube near the tank body bottom in the lower end of sleeve pipe, according to the silt depth of floater and tank body bottom, adjusts the height of upflow tube.

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