Abstract

PURPOSE:To improve the efficiency of agitation and the efficiency of using air, by spraying at least air through the top part of a flexible elastic rotary pipe so that the rotary pipe is rotated about its base side by the spraying pressure. CONSTITUTION:Compressed air from an air compressor is fed through an inflow pipe 1 and a joint 3 into a rotary pipe 2. Since the rotary pipe 2 is a flexible elastic one, it is curved downwards as shown in B under the condition that the compressed air is not let flow into it. When the compressed air is let flow into it, it sprays air a through ejecting holes 4 under a condition held horizontally as shown in A or curved upwards by the buoyancy of the air and begins to rotate with the resulting reaction force R. The agitation of filthy water can be sufficiently carried out in this apparatus without the need to consume any power for rotation, and the efficiency of dissolving the air in the filthy water can be remarkably improved by said agitation.

Description

[Detailed Description of the Invention] In recent years, water stagnation due to land reclamation, whether sea water or rough water,
The deterioration of water quality has become remarkable due to the lack of dissolved rR elements and the accumulation of harmful sludge.

Therefore, in the past, application air was ejected at a circulating position in the wastewater, and the upward flow of the rising bubbles agitated the wastewater, giving dissolved oxygen to the wastewater and treating the microorganisms, but this method did not provide sufficient agitation. Therefore, the air bathing efficiency, that is, the air usage efficiency was also poor.

In view of the above points, the present invention has been made for the purpose of providing a sewage treatment apparatus that has an extremely simple and inexpensive structure and has excellent agitation efficiency and air usage efficiency.

Below, the present invention will be explained based on the embodiment shown in FIG.
As shown in Figure 2.3, this device has a non-flexible compressed air feed θ unit installed vertically in the waste water, and a flexible elastic rotating pipe that can be rotated freely in the feed pipe 1. The base of a2 is connected, and the rotating tube 20
The base and the feed pipe are connected to the air supply nT sl even during rotation of the rotary pipe, and the pressure M air outlet 4 Bd at the tip of the rotary pipe 3 is connected to the air supply nT sl.
, the rotary tube rotational force is stopped by the reaction force R of the desired air ejection.

In addition, the base of 11J, 4-way feed pipe 1 and rotary pipe 2 is joint 3.
connected with. Further, the upper part of the feed pipe 1 is erected on the water surface, and the upper part is connected to an air compressor on land through piping. The elastic rotary tube 2 is made of, for example, a synthetic resin tube in which a coil spring 5 is embedded. The rotary tube 2+'i rotates due to the reaction force R of the air jet.The shackle joint 3 is connected to the inlet 6 of the 11 rotary tube 2, and the inner case is fixed.
A case receiver eJs fitted inside the case 7 and fixed to the feed pipe 1, an outlet 9 bored in the feed pipe l, and the case 7.
and a bearing 10 interposed between the bearing 4gs.

Did support floating body.

Next, to explain the operation, the compressed air brought into the feed pipe by the air pressure kl+N is transferred from the feed pipe l to the i+h L joint 3 into the feed pipe during rotation W2. Here, the rotation - [¥2 is a flexible elastic bone, so when compressed air is inserted, I curves and bends to the hitting knife shown in the diagram at B, but the compressed air is sent. Status +7! , it rises to the buoyancy of the air, and as shown in the figure, it blows out air a from the jet nozzle 4 in a horizontal and upwardly bent state as shown in the figure, and the reaction force R causes it to start rotating.

At this time, when this apparatus shown in FIG. 2 is installed in a sewage tank 11 having a rectangular planar shape, the tank wall corner 12 far from the inlet pipe 1 is in a straight line state in plan view close to the shape when the two rotating pipes are free. rotates to agitate the sewage in the tank wall corner 12 without leaving any residue,
It also rotates a little, and in the middle part 13 of the tank wall, it is elastically deformed by rotating @2 and hits the tank wall, and rotates in a large westward rotation state, and rotates continuously as if stirring the sewage. and spout 4
Since the air ejected from the tank rises while being uniformly dispersed throughout the area, the air efficiently enters the VC bath in the wastewater. Next, another embodiment of the present invention will be explained with reference to Fig. 4.5. 1. The bases 2C of two flexible elastic rotary tubes 2 are fixedly connected to the cylindrical fixed joint 3 of the compressed air feed pipe 1, and the rotary tubes 2 rotate around the bases 2c. It is made freely (elastically deformable) and is formed so that the rotating force of the rotary tube is stopped by the reaction force R of the compressed air jet port 4 at the tip of the rotary tube 2 and the air jet. The sewage tank 14 is a partition wall that prevents the two rotary pipes 2 from getting dirty with each other.

In this example, the reaction force R corresponding to the compressed air jetted out from the jet nozzle 4 causes the rotary tube 2#-i to rotate at its base 2C.
The sewage is repeatedly rotated (elastically deformed) between the partition walls 14 at an angle of about 180° while deforming into various meandering postures around the tank wall corner 4124 to agitate the sewage without leaving any residue. Note that this deformed meandering state is similar to the state in which a water hose meanders when the hose is released when watering.

In each of the above embodiments, an example in which only air is jetted out has been explained, but in order to increase the reaction force R at the time of jetting, that is, the rotational force of the rotating tube 2, air and water having a higher specific gravity must be combined. may be ejected at the same time; in this case, a mixture of air and water is sent into the feed pipe.

As is clear from the above explanation, in the present invention ψ, at least air is ejected from the tip of the flexible elastic rotating tube, and the ejection reaction force causes the rotating tube to rotate (elastic deformation) around its base side. Because of this structure, the sewage can be sufficiently agitated without requiring any rotational power, and this agitation can be expected to have excellent effects such as significantly improving the efficiency of air bathing in the sewage, that is, the air usage efficiency. .
