The present invention is to supply air to the aeration tank of the water treatment apparatus used to treat sewage and waste water,

More specifically, the injection hole is installed to make a uniform aeration on the whole surface, and after forming the entire product into a finished product, fixing it to the floor, and then connecting the main pipe, the piping device of the aeration tank using a synthetic resin to easily complete the construction and It relates to a manufacturing method.

In general, the wastewater, sewage and sewage discharged from the home are directly discharged into the stream to prevent the contamination of the stream, so that the wastewater and sewage flow into the treatment plant to purify the wastewater and sewage, and then discharge it into the stream. Rivers have been prevented from being polluted.

The wastewater and sewage treatment system is divided into sedimentation tank and aeration tank, and the wastewater flows into the sedimentation tank, and then sediment of foreign substances and the rest flows into the aeration tank, and oxygen is supplied from the aeration tank and supplied from the aeration tank. It is transformed into an aeration tank under aerobic conditions in which dissolved oxygen is present to help activate microorganisms and lower BOD.

By the way, the apparatus for supplying air to the conventional aeration tank is provided through a plurality of diffusers formed on one end of the air supply pipe installed on the lower side of the inner aeration tank, as registered in Korea Utility Model Registration No. 276280 (registered May 9, 2002). To supply air.

In addition, as in Korea Utility Model Registration No. 331005 (registered on Oct. 13, 2003), a combination of submersible pump and ejector was able to supply a large amount of air into the water.

In addition, Korean Utility Model Registration No. 333858 (registered Nov. 11, 2003) oxidizes and aerobic bacteria through the operation of blowing air into the water in the aeration tank of the wastewater treatment plant using the activated sludge method to bring water and air into sufficient contact. By promoting the digestive action by the microorganism was to remove carbon dioxide, hydrogen sulfide, methane gas and the like by the digestion.

In addition, Korean Patent Registration No. 461491 (registered on Dec. 2, 2004) is provided by an acid engine that supplies oxygen to raise dissolved oxygen in an aeration tank when cultivating microorganisms that treat various organic substances contained in sewage or wastewater. When partially broken, only broken lines were lifted for repair.

As such, it can be seen that the conventional water treatment apparatus has an object to improve the amount of supply of air through most of the diffuser.

However, most of the existing aeration tank pipe line is installed as a pipe, so it keeps in contact with air and water all the time, so that the pipe itself is easily corroded and should be replaced every 3 to 5 years. In order to use SUS piping, the cost of piping is high, and the cost of labor is very high as a connection method through welding during construction, so the facility investment is excessively applied and there is a defect that is not free from corrosion.

The present invention has been devised to solve such a conventional defect, it is possible to use semi-permanent by installing a synthetic resin pipe with no corrosion in a pipe line, and protrudes from the main pipe at a distance away from the bottom of the aeration tank By varying the length of the branch pipe to enable uniform aeration over the entire surface to improve the purification efficiency.

The present invention is to be able to perform the work simply by molding the finished product in the required space without construction in the field so that the construction is completed by simply connecting in the field.

The present invention is to be freely adjusted according to the size of the aeration tank by adjusting the number of installation of the branch pipe in accordance with the length of the main pipe to be made easily.

The present invention is to install the closing cap that can be easily assembled and detached to both sides of the main pipe to clean the inside of the main pipe.

The outer side of the saddle branch pipe 12 is a screw is formed therein or the screw shaft to protrude so as to be connected to the branch pipe (13, 13 ') screw type.

The branch pipes 13 and 13 'are connected so that the lengths protruding to both sides are different from each other, and a threaded portion 16 is formed at a tip thereof so that the injection hole 15 is connected downwardly through the elbow 14, or the threaded portion ( 16 is to be directly connected to the injection hole (15 ').

The protruding position of the branch pipes 13 and 13 'is to be W-shaped, and the threaded portion 21 is formed on the outer side of the main pipes 11 and 11' so that the inside penetrates, and the finishing cap to the outside. (20, 20 ') are connected.

The main pipes 11 and 11 'forming the main pipe member 10 can freely adjust the number of branch pipes 13 protruding by freely adjusting the length and the number of holes, and the main pipes 11 and 11'. ) Is determined in advance by the length and the number of connections of the branch pipe 13 is molded and then connected to form a one-piece by fusion through the butt joint 31.

The main tube member 10 is installed in the aeration tank 60 and is installed at a position protruding to the ground through the pipe fixing device 50 without being installed at the bottom.

Pipe fixing device 50 is installed on both sides is the main pipe (11, 11 ') is raised, connect the supporting leg 52 to the lower side of the fixing frame 51 to be located at a constant height from the ground, the main When the pipes 11 and 11 'are raised, they are respectively wrapped in the U bolts 53 on both sides, and then fixed to the nuts 55 by penetrating the fixture 54.

The present invention made of this configuration is completed by fixing the connecting flange 32 to the T-shaped main connecting pipe 30, and determines the length of the main pipe member 10 and the number of branch pipes 13 to be connected to both sides. do.

When the number of branch pipes 13 is determined, the main pipes 11 and 11 'are cut to a fixed length and placed on a jig pre-installed on the drill machine to fix the main pipes 11 and 11'.

The main pipes 11 and 11 'fixed to the jig drill holes by a determined number, and then rotate the main pipes 11 and 11' by 90 ° to drill holes at positions symmetric to the drilled holes.

When the hole is punctured, the portion where the saddle branch pipe 12 meets is heated by heating the hot plate, and both sides of the heated hot plate are melted to form the periphery of the perforated hole and the saddle branch pipe 12 and then heated. The saddle branch pipe 12 is fusion-fixed to the main pipes 11 and 11 'by removing and removing the melted portion by pressing and cooling.

When the saddle branch pipe 12 is fixed to the main pipes 11 and 11 ', fusion is completed by supplying the molten resin around the saddle branch pipe 12 in the same manner as the method of caulking the molten resin.

When the connection of the saddle branch pipe 12 to the main pipe (11, 11 ') is completed, the branch pipe (13, 13') is connected to the outside of the saddle branch pipe (12).

The branch pipes 13 and 13 'connected to each other are long and short on one side, and branch pipes 13 and 13' positioned at both sides are connected in different lengths, resulting in branch pipes ( 13) is integrally connected as shown in FIGS. 1 and 2 and 4 so as to maintain the W shape.

In the case of connecting the protruding lengths of the branch pipes 13 and 13 'differently, since the positions of the injection holes 15 are different from each other in the shape of W in a plan view, air can be uniformly supplied to the entire surface of the aeration tank 60. will be.

The saddle branch pipe 12 to which the branch pipe 13 is connected has a screw formed with an inner diameter of the outer side or a screw formed in a state that protrudes to the outside, and the branch pipe 13, 13 ′ according to the shape of the screw. By varying the shape of the screw formed in the can be connected in various ways.

When the connection of the branch pipes 13 and 13 'is completed, the elbow 14 is connected to the outside, but the threaded portion 16 protrudes or is formed in the inner diameter so that the shape of the elbow 14 can be changed. ) Can be connected to the injection hole 15 for injecting air to the lower side, or as shown in Figure 6 can be directly connected to the branch pipe (13, 13 ') without the use of the elbow (14). .
