Description

The object of the lazku ^to a device for mixing a liquid and napowwetrzania especially wastewater. The device is intended for simultaneous re-injection and mixing of sewage and stimulating the movement of liquids in the biological treatment of sewage by the activated sludge method.

A device for aeration of sewage from the Polish utility model Ru 47 941 is known. This device has a bearing mounted in the housing 1 connected by a coupling to the shaft of the electric motor. At the other end of the shaft, there is a propeller in a cylindrical casing. A tube is attached to the housing and adjoins the propeller. A conical ring is attached to the end of the pipe from the side of the propeller.

The essence of mŁLszek is a device for reprocessing and mixing liquids with a pipe which is connected with the shaft at one end of the engine, while the other end of the pipe is ended with a propeller, and behind the propeller there is a clear nozzle with a pipe. Moreover, the pipe is equipped with inlet holes located at the motor shaft. The O3 device achieves the highest u parameters

working if the ratio of the propeller to its diameter of from 0.5 to 2 (p - 0.5 - 2), and ^k Relations in the outer re ^{COG d y's} dis ^foo to the diameter of the propeller O ^y and ^{n03 d} ° C, 2 ⁵ 0.7 ^{5 (} § ·> 0 ^, 2 ⁵ - ^0.75) .

Another embodiment of l O ^{on a} Relationship is a device for napowwetrzania 1 ^ m ^ la sszai liquid having a tube which at one end is connected to the motor shaft and the other end of the tube terminates in a propeller, the propeller positioned in front of the nozzle is not obstructed with the pipe. In addition, the tube is equipped with inlet holes and gauged at the motor shaft. The device achieves the highest operating pa rametry, when the propeller pitch ratio to its diameter is ¹¹⁰³ ! · About 0.5 to 2 (p> 0.5 - 2), while the ratio of the outer diameter of the nozzle to the propeller diameter is wr ⁿ⁰³ and from 0.25 to 0.75 (g = 0.25 - 0.75).

In another embodiment ^{at a} l Relationship napowwetrzania a device for mixing a liquid 1 having a tube which at one end is connected to the motor shaft and the other end of the tube attached zakoń163 24ο Jeat propeller, and the propeller and a propeller attached before the nozzles are not obstructed with the pipe.

In addition, the pipe is equipped with inlet holes located at the motor shaft. The device achieves the highest operating parameters when the propeller pitch ratio to its diameter is ⁰³ ! from 0.3 to 2 u

(g - 0.3 - 2), while the ratio of the windward diameter of the nozzle to the propeller diameter is from 0.23 to 0.75 (g - 0.25 - 0.75).

Object of the invention It is shown in the exemplary embodiments in the drawing, in which fig. 1 shows a device for winding and mixing liquids in an axial leaf section with respect to the solution given in the first example, fig. 2 - in the second example, Fig. 3 is a third example.

The first example shows the device shown in Fig. 1. The device consists of a pipe 1 connected at one end to the shaft of the motor 2 through a coupling 3. The long end of the pipe 1 ends with a propeller 4, while behind the propeller there is a nozzle 5 that is cleared with the pipe 1. Moreover, the pipe 1 It is equipped with inlet openings 6.

The second example shows the device shown in Fig. 2. The device consists of a pipe 7 connected with one end to the shaft of the motor 8 through a coupling 9. The other end of the pipe 7 ends with a propeller 1o, and a nozzle 11 is placed in front of the pipe ⁷ . The pipe 7, on the other hand, grows into the inlet holes 12.

The third example shows the device shown in Fig. 3. The device consists of a pipe 13 connected at one end to the motor shaft 14 through a coupling 15. The other end of the pipe 13 ends with a propeller 16, while behind the propeller 1, there are 3 nozzles 17 1 1θ in front of the propeller. unblocked with pipe 13. Moreover, pipe 13 is equipped with inlet openings 19.
