Abstract

PURPOSE:To carry out agitation, aeration, etc. in a region with a simple and inexpensive structure by causing the combined movements of waving, turning, etc. to a working pipe in the region by utilizing the reaction, etc. of an optional fluid spouted from the injection part of the working pipe obtained by connecting an appropriate number of unit elastic pipes. CONSTITUTION:An appropriate number of unit pipes 2 having optional length and consisting of an elastic material are connected to obtain a working pipe 1 provided with an appropriate injection part 3 at its leading end and which is positioned in the working region in waver W. The base part of the working pipe 1 rising vertically from almost the center of the working region is fixed by a fixing part 4 at the upper outside of the working region. The combined movements of waving, twisting, bending, turning, etc. are caused to the working pipe 1 by the reaction of an optional fluid spouted from the injection part 3, and the planar working region is stirred by the movements and mainly by the action of the injection part. The agitation, aeration, etc. in the region are carried out in this way. Consequently, the agitation, aeration, etc. in the region can be carried out with high energy efficiency by such a simple and inexpensive structure.

Description

[Detailed description of the invention] The present invention mainly relates to agitation (including prevention of consolidation) in water.
, aeration (including air backwashing), etc.

In recent years, water stagnation due to land reclamation, whether seawater or freshwater,
It is well known that water quality is significantly deteriorating due to lack of dissolved oxygen, deposition of harmful sludge, etc. Such water treatment methods can be roughly divided into treatment of domestic water, tap water, industrial water, agricultural water, etc. for use or during use, and treatment of wastewater after use. During these treatments, it is often necessary to perform a stirring action, an aeration action, or a combination of both. In addition, it is necessary to compact the generated sludge, prevent its adhesion, and remove and move the sludge.In addition, it is necessary to perform aeration-related treatments such as biological treatment, which is the mainstay of wastewater treatment (recently, pre-treatment of water (also used).

Currently, these methods require large equipment such as sludge collectors to be installed during the treatment of water, sewage, and wastewater, but such sufficient equipment is not available for small biological treatment tanks such as human waste septic tanks. There was also room to consider rational methods for air backwashing of biological fixed beds.

In view of this problem, the present invention has an extremely simple and inexpensive structure in which an appropriate number of single tubes of arbitrary length made of elastic material are connected together in order to achieve a stirring or aeration effect. An operating tube provided with an appropriate spout is positioned in the underwater action area, and the base of the actuator tube rising perpendicularly from the approximate center of the action area is fixed outside the upper area, and the tip jet orifice is fixed at a position outside the upper area. The actuating tube is given complex movements such as waviness, twisting, bending, and reversal due to the reaction force of any fluid ejected from the pipe, and this movement mainly causes the ejection port to move in a substantially sliding state in the planar action area, The present invention is intended to present a water treatment device configured to perform stirring, rice-boiling, etc. functions in the same area.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

An operating pipe ↓ (hose, tube) located in any underwater W such as water or chemical solution is a pipe that can pump a single fluid such as gas or liquid, and the material is elastically deformable such as waviness, twisting, bending, etc. A single tube 2, 2.
An appropriate number of ... are connected to form one operating pipe ↓. The operating pipe ↓ is located in the planar action area of the underwater W, and
An appropriate spout 3 for spouting fluid in the axial direction is provided at the end of the single tube 2 located at its tip. The base side of the actuating tube is curved upward at a right angle from the approximate center of the acting area, and a fixing part 4 is provided outside the upper area.
A fluid pump such as a pump or a compressor (at the fixed part 4 or at a part further away from the fixed part 4)
(not shown). A holding part 5 is provided below the fixed part 4, and the holding part 5 holds the actuating tube so that it can be freely twisted.

Actuation pipe located in the planar action area in the underwater W↓
The jet nozzle 3 at the tip mainly moves over a planar action area due to complex movements such as waviness, twisting, bending, and reversal due to the reaction force of the fluid ejected in the axial direction from the jet nozzle 3 disposed at the tip. It is configured to operate in a substantially sliding state.

As described above, the present invention connects an appropriate number of single tubes 2, 2, etc. of arbitrary length made of elastic material, and connects an operating tube ↓ with an appropriate spout 3 at its tip to the action of underwater W. located in the area,
The base of the actuating tube unit rising in a right angle direction from approximately the center of the acting area is fixed 4 outside the upper area, and the actuating tube is not undulated or twisted by the reaction force of any fluid ejected from the tip outlet 3. , bending, reversing, etc., and by this movement, the jet nozzle 3 mainly moves the planar action area in a substantially sliding state, and is configured to perform stirring, rice stirring, etc. in the same area. Since it is a device, the operating tube↓
By connecting the single tubes 2, 2, . . . , it is possible to correct the curvature caused by winding the elastic tube during the manufacturing process, and to obtain an operating tube that operates smoothly.

The movement on the working tube is due to the reaction force of the jet, etc.
Since it is an elastic tube, it bends and bends repeatedly. When the working tube ↓ is long, it becomes undulating, but the jet nozzle 3 at the tip only moves along the same trajectory within a generally fixed and limited range. Therefore, in order to move the spout 3 uniformly over a wide range, it is necessary to slide on the surface so that the action area is flat or to maintain a balanced state in the water (by installing a heavy suspension or float etc. at the connection part). The weight of the tube is set to balance the weight, and the holding portion 5 is located perpendicular to its working surface. Furthermore, in addition to the undulations and twists on the actuating tube, the bending is approximately one rotation or more (resulting in a circular shape), and in order to have the reversal effect in which the jet nozzle 3 is turned inside out, the actuating tube ↓ must be configured. The material, length, inner and outer diameter of the necessary parts of the single tube 2, 2..., and the single tube 2 located at the tip
By giving appropriate conditions to the diameter of the jet nozzle 3 and the feeding pressure, etc., we can set the elastic parts related to the compound movement of the actuating tube ↓ and the wide-area action of the tube, for example, make the single tube 2 on the tip side relatively hard. As an elastic tube,
The single tube 2 located at the curved portion can be a soft elastic tube. In addition, the pressure of the fluid to operate the operating pipe ↓ may be under economical and relatively low pressure conditions (approximately 1 to 5 kg 'cj) and the existing water pressure, regardless of whether the fluid is air or water. Therefore, even in human waste septic tanks, etc., where sufficient treatment equipment was not available in the past, water can be used in existing tap water without having to be pumped, and by periodically jetting out tap water, the effects of water at the bottom of the septic tank can be improved. It is a simple device with only an operating pipe ↓ and a spout 3, so it is very economical compared to conventional devices. In addition, it is very energy efficient as the energy emitted is minute only at the ejection point, and it has a new field in addition to air backwashing, which has a slow and slow usage that affects the entire required area. .
