Abstract

PURPOSE:To treat efficiently sewage by the intermittent use of two water treating tanks by installing travelling trucks travelling between the water treating tanks bestriding >= two adjacent water treating tanks, and supplying the air sucked by the negative pressure generated by the stirring of the water to the trevelling trucks. CONSTITUTION:Each water tank A, B is constructed to an elliptic ring shape, and rails 1 are provided to bestride the tanks A, B. Two rails are faced each other to form one pair, and at least a pair or two pairs of rails are provided with each one travelling truck 2 capable of travelling between the tanks A, B, by itself. While the stirring by the dispersion of air is performed in the tank A, the tank B is made to serve as a settling tank. In this stage, the air-dispersing stirrer 3 is set on the tank A. After the desired treatment is finished, the function of the tank A and B is exchanged. This exchange of the function of tanks is attained by only moving the air-dispersing stirrer and intermittent utilization of the water tanks is realized.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mobile aeration agitation device that supplies air to liquids to be treated, such as sewage, wastewater, and industrial water, and agitates the liquids while making them aerobic. In a plurality of treated water tanks, an aeration agitation device equipped with a simple lifting device is mounted on a traveling trolley and moved over two or more types, so that the tanks can be used intermittently. It is.

For sewage treatment, etc., when a large number of treated water tanks are arranged adjacent to each other, conventional aeration agitation devices are either horizontal or vertical, or have their own liquid guiding device attached to the agitation device. Therefore, the aeration agitation device must be a unique device for the relevant aquarium waterway.

Therefore, since an aeration stirring device is installed in each water tank, there is a drawback that the equipment cost is high.

In view of this, the present invention provides a single aeration agitation device for each tank by providing a single aeration agitation device on an adjacent water tank or a traveling truck that runs an oil volume, so that the aeration agitation device can be raised and lowered. In addition, the intermittent use of water tanks is intended to efficiently treat sewage, etc.

The present invention will be explained below based on illustrated embodiments.

In the figure, A and B are treated water tanks (or ponds) adjacent to each other.
In the figure, there are two rows, but there may be a plurality of rows. The two-tank type will be described below. Each of the water tanks A and B is formed in an elliptical ring shape, and a rail 1 is provided to cross between the water tanks A and B. The rails 1 are provided in at least one pair or two pairs as shown in the figure, with two rails facing each other, and a traveling trolley 2 is disposed on each rail 1, and the traveling trolley 2 is moved between the water tanks A and B. A traveling device is provided to allow the robot to run on its own. This traveling platform bundle 2 is @ 111
In the figure, it is located in one water tank A, and in the second figure, it is shown running and moved to the water tank B side, and one or two aeration stirring devices 3 are vertically installed on the trolley. This aeration stirring device 3 is provided with a hollow shaft 32 that is directly connected to a motor 31, these are housed in a cover 63, and a stirring propeller 34 is attached to the tip of the shaft 32. 32 is provided with a suction hole 35 for taking in air or gas, communicating with a hollow hole in the hollow shaft, the tip of the hollow hole is opened at the tip of the propeller 34, and the cover 33 has a suction hole 35 for taking in air. An opening is formed. As a result, when the propeller 34 is rotated by the motor 31, a negative pressure is generated at the tip of the hollow shaft 32 by the stirring water flow, and air or gas is released into the water through the hollow hole in the hollow shaft.

When this aeration agitation device 3 is installed on the traveling vehicle 2, it is constructed and tilted as shown in FIG. 5. That is, a support @I14, which is the center of tilting and rotation of the entire body of the device, is provided protruding from the upper part of the device 3, and this support shaft 4 is supported by a bracket 5 for attaching the aeration agitation device, which is provided on the traveling truck. In this bracket 5, the bending position of the two 5-shaped links 6°7 is set to the pin P1. A connecting link is pivotally connected at P2, the upper ends of these two links 6.7 are arranged parallel to the plait 5, and the connecting link is engaged with a part of the operating lever 8 which is pivotally connected to the plastic foot. The lower end of the link 6.7 is parallel to the connecting link 9, and the lower end of the link 10 is pivotally connected to the link 10 at the lower part of the air agitation device.
5. The parallelogram links are all formed by the secondary links 6, 7, and 10 and the connecting links 9, which are pivoted through P6.

Then, the 51iU
Operate as in (A), immerse the stirring propeller in the liquid, drive the stirring propeller to achieve the desired stirring, and use the negative pressure generated in the liquid to suck air or gas and create bubbles in the liquid. Aeration is diffused and the desired treatment is carried out. Before moving the traveling cart to move this device to the other water tank side, when the operating lever 8 is tilted in the direction of the arrow as shown at 51 mB, the link 6 is connected to the connecting link 9 connected to this operating lever. At 7.10 degrees, the parallelogram links are deformed about each pivot axis, and the lower part of the stirring device becomes horizontal and lifts above the liquid level.

This is determined in advance by the relative relationship between the length of the link, the pivot point, etc., and if the aeration agitation device is lifted up and moved between tanks as shown in No. 51W (B), it can be moved without any problem. 5 (A) by using the operating lever again after moving.
) If the device is tilted, it can be reused.

The above-mentioned aeration stirring device 3 has been described with reference to an embodiment in which a running trolley is suspended and supported on a rail on a pond.

A running cart may be provided on rails so as to run on the pond.

Therefore, when performing aeration agitation in tank A and using pond tank B as a settling tank, install aeration agitation device 3 in tank A, and once the desired treatment is completed, tank A and tank B will be connected. The roles can be exchanged, but this only requires moving the aeration agitation device, and the tank can be used intermittently.

According to the present invention, in a multi-channel facility where aeration and aeration/agitation are performed intermittently or alternately, the number of aeration/agitation devices is halved, resulting in lower equipment costs. The aeration agitation device can be pulled up from inside, which improves the weight resistance of the device, and the trolley can be stopped on the ground or on the floor midway between the two tanks, allowing the aeration agitation device to be safely and safely placed on the ground or on the floor. It has many advantages, such as being easy to inspect and improving the utilization and work efficiency of the tank since there is no inherent aeration stirring device in the tank when aeration stirring is not required.

Claims (1)

[Claims] A traveling trolley is installed between at least two adjacent treatment water tanks so as to move between the two tanks, and at the same time as the liquid is stirred, gas is supplied to the traveling trolley by utilizing the negative pressure generated by the stirring of the liquid. This is a mobile aeration agitation device which is equipped with an aeration agitation device that can be tilted freely to suck and supply and mix gas into the liquid.
