Description

[0001] Apparatus of removing residual water [0002]

The present invention relates to a wastewater treatment apparatus, and more particularly, to a wastewater treatment apparatus for removing residual water remaining on the floor of an indoor or outdoor workplace.

Generally, a work structure having a large size such as a ship is subjected to various operations such as painting, drying, and welding in the open air. However, since the outdoor workplace is exposed to the outside, it is greatly affected by environmental factors such as heavy rain or heavy snow, and the worksite is damaged.

For example, if a large amount of rainfall occurs due to rainy or heavy rainfall, the rainwater on the floor of the outdoor workplace may not drain properly.

Because of the wires and various gas hoses required for the work at the floor of the outdoor workshop, various problems arise if the rainwater is not properly drained to the floor of the outdoor workplace.

As mentioned above, the problems caused by residual water not draining to the floor of the workplace outdoors or indoors are as follows.

First, electric current may flow out of various wires due to the residual power, so there may be a short circuit, so that there is a problem that various safety accidents such as electric shock or workplace fire occur.

Second, since the worker can not perform work such as welding at the floor of the worksite in the outdoor or indoor by the residual water, there is a problem that the work efficiency is lowered because it is difficult for the worker to smoothly work the work structure.

Third, there is a problem that the parts to be used in the work structure are damaged, such as corrosion of the parts when the parts of the work structure are exposed to the residual water for a long time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIG. 1 is a perspective view showing a wastewater treatment apparatus according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view showing a cross section of the wastewater treatment apparatus of FIG.

1 and 2, the wastewater treatment apparatus according to the present embodiment is simple in installation, easy to carry, and capable of rapidly treating residual water on the floor of the indoor or outdoor workplace. The wastewater treatment apparatus includes a pipe unit 100, , And a compressed air injection unit (200).

The pipe unit 100 has a main pipe 110 and a branch pipe 120 protruding from the main pipe 110.

Specifically, the main pipe 110 has a pipe inlet portion 111 and a pipe outlet portion 112.

The pipe inlet portion 111 is connected to the hose 10 to introduce fluid. In the pipe outlet portion 112, the fluid introduced from the pipe inlet portion 111 flows out.

The main pipe 110 further includes a pipe connection part 113 to which the pipe inlet part 111 and the pipe outlet part 112 are connected.

As a result, the fluid flows through the main pipe 110. The fluid flows through the pipe inlet 111 and flows out of the pipe outlet 113 through the pipe connection 113 to the pipe outlet 112.

In this embodiment, the pipe connecting portion 113 is a venturi type.

Here, the venturi means a narrow passage. When the fluid flows through the pipe connecting portion 113, the pressure in the pipe connecting portion 113 is lowered by Bernoulli's theorem. Therefore, the fluid flowing into the pipe inlet 111 is sucked at a high speed.

As a result, since the pipe connection portion 113 is formed in a venturi shape, the fluid quickly flows out to the pipe outlet portion 112 through the pipe connection portion 113, The work efficiency can be increased by rapidly processing the residuals.

The branch pipe 120 protrudes from the main pipe 110. More specifically, the branch pipe 120 protrudes from one side of the pipe inlet part 111. [

The compressed air supplied from the external compressed air supply source 20 is injected from the branch pipe 120 formed in the pipe inlet portion 111 into the internal space of the pipe inlet portion 111.

The compressed air injection unit 200 is coupled to the branch pipe 120.

The compressed air injection unit 200 injects the compressed air supplied from the external compressed air supply source 20 into the space inside the pipe inlet part 111 connected to the branch pipe 120.

As a result, the pressure of the inner space of the pipe inlet part 111 is changed by the air flow of the compressed air, and the fluid is sucked into the pipe inlet part 111.

In this embodiment, since the fluid is sucked into the pipe inlet portion 111 and flows out to the pipe outlet portion 112, residual water in the outdoor or indoor work place can be treated, Accidents can be prevented, and damage to components used in the work structure exposed to residuals can be prevented.

The compressed air injection unit 200 includes an injection pipe 210, a valve unit 220, and a compressed air supply line unit 230.

The injection pipe 210 is accommodated in the branch pipe 120 and at least part of the injection pipe 210 is accommodated in the pipe inlet part 111 to inject the compressor.

One end of the injection pipe 210 is connected to the valve unit 220 in the branch pipe 120 and the other end is disposed in a central area of the inner space of the pipe inlet unit 111.

The valve unit 220 is connected to the injection pipe 210 to adjust the flow rate of the compressed air.

Here, the valve unit 220 is provided with an opening / closing control lever 221. The opening / closing control lever 221 controls opening / closing of a valve (not shown) provided in the valve unit 220.

The valve unit 220 controls the flow rate of the compressed air, and the valve must be opened or closed to adjust the flow rate of the compressed air supplied to the injection pipe 210. Therefore, it is preferable that the opening / closing control lever 221 is provided on the valve 220 to control whether the valve is opened or closed.

The compressed air supply line unit 230 has one end coupled to the valve unit 220 and the other end connected to the external compressed air supply source.

That is, the compressed air supplied from the external compressed air supply source 20 is supplied to the injection pipe 210 while the flow rate of the compressed air is controlled by the valve unit 220 through the compressed air supply line unit 230.

Herein, various types of apparatuses may be used as the external compressed air supply source 20. However, in the present embodiment, an air compressor (not shown) for compressively producing air and storing the compressed air at a high air pressure, an air compressor is preferably used.

In this embodiment, the wastewater treatment apparatus is easy to carry and is easily assembled and installed, so that the worker can smoothly carry out work such as painting, drying, and welding of the structure to be worked, and work efficiency can be increased.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
