Abstract

The utility model relates to a pneumatic sludge lifting apparatus, which comprises an air distribution tank, an air supply pipe, a liquid lifting pipe, a reducer pipe, and supporting feet. The liquid lifting pipe penetrates through the air distribution tank and is connected with the reducer pipe on the lower part; a liquid lifting pipe segment in the air distribution tank is provided with an air hole at the side opposite to the air supply pipe. The height of sludge lifted by the utility model is comparatively high, the lifting requirement of the sludge in sewage disposal works can be met, and additional energy consumption is not needed.

Description

Aerodynamic force mud lifter

The utility model relates to a kind of mud lift technique, and being meant a kind of especially is the mud lifter of power with the air, and the mud that is used for sewage treatment project promotes and backflow.

Existing aerodynamic force mud lifter is to feed a thinner air-supply duct in the thicker riser pipe that is located in the sewer catch basin from the bottom, utilize the inside and outside density of liquid difference of riser pipe and mud is promoted, the utilization ratio of its air is low, and the height of lifting is little, is restricted in the practical application.

The purpose of this utility model provides a kind of aerodynamic force mud lifter with big lift height, after air feeds the gas distribution tank, enter riser pipe by many pores of offering on the riser pipe, the contact area of air and mud is increased, the utilization ratio of air improves, and the height of lifting strengthens.

The purpose of this utility model is realized by following technical scheme, this lifter is made of gas distribution tank, air-supply duct, riser pipe, adapter bonnet and leg, wherein, the air-supply duct caliber carefully and with the gas distribution tank communicates, the riser pipe caliber is thick also vertically through the gas distribution tank, the lower end of riser pipe with become through managing corresponding connection, riser pipe Duan Yu in a gas distribution tank side of air-supply duct dorsad has several pores, adapter bonnet is bell mouth shape, Open Side Down, and be equiped with leg in opening part.

The principle of work of the utility model aerodynamic force mud lifter is: air passes through air-supply duct under the effect of certain pressure, enter the gas distribution tank, enter in the riser pipe than small bubbles by the generation of the pore on the riser pipe, bubble rises and forms negative pressure on pipe top on the one hand in riser pipe, on the other hand since in the pipe mud adhered to bubble and make and produced density difference inside and outside the pipe, thereby in riser pipe, produced bigger unlifting pressure, mud is got a promotion.

Compared with prior art, the obvious advantage that the utlity model has is:

1, increased the mud lift height: air can enter riser pipe by many apertures, the bigger air utilization ratio that improved; Aperture is located on the riser pipe wall, and air is distributed to aperture by the gas distribution tank of riser pipe overcoat, makes no any obstacle in the riser pipe, and mud is mobile smooth and easy in pipe; The hydraucone structure is adopted in the riser pipe lower end, helps sucking mud, and therefore the bigger mud lift height that increased can satisfy the requirement that mud promotes in the large, medium and small type sewage treatment project.

2, stable performance: because this lifter does not have rotatable parts, gas distributing system simple, thereby sturdy and durable, reliable operation.

3, running cost is low: because its working process has only been utilized the residue air pressure of blower fan, and no additional source of energy consumption, thereby reduced running cost.

In conjunction with the accompanying drawings and embodiments the utility model is described in further detail:

Fig. 1 is an outside drawing of the present utility model.

Fig. 2 is a longitudinal sectional drawing of the present utility model.

Fig. 3 is a transverse cross-sectional view of the present utility model.

Number in the figure is described as follows:

1, gas distribution tank 2, air-supply duct 3, riser pipe

4, adapter bonnet 5, leg 6, pore

The described aerodynamic force mud of present embodiment lifter, by gas distribution tank 1, air-supply duct 2, riser pipe 3, adapter bonnet 4 and leg 5 constitute, wherein, gas distribution tank 1 is cylindrical, air-supply duct 2 calibers are thinner, be located at the top of gas distribution tank 1 and communicate with it, thick also the setting vertically of riser pipe 3 calibers passed gas distribution tank 1, the lower end of riser pipe 3 with become through managing 4 corresponding connections, riser pipe Duan Yu in a gas distribution tank side of air-supply duct dorsad has many pores 6, adapter bonnet 4 is bell mouth shape, and Open Side Down, and is equiped with the leg 5 of three pin in opening part.

Air with certain pressure feeds air-supply duct 2, enter cylindrical gas distribution tank 1, produce than small bubbles by the pore on the riser pipe 3, bubble enters in the riser pipe, bubble rises and forms negative pressure on pipe top on the one hand in riser pipe, on the other hand since in the pipe mud adhered to bubble and make and produced density difference inside and outside the pipe, thereby in riser pipe, produced bigger unlifting pressure, mud is got a promotion, change helps inhaling mud downwards through managing 4 hydraucone, and the leg of installing on it is used to bear airlift weight and provides certain space for mud flows into.
