Description

Wastewater purification apparatus using centrifugal blower {An Apparatus for Cleaning Wastewater}

The present invention is to purify the waste water, in particular, the air pump for supplying air to the inside of the purifier can increase the efficiency of blowing the air while significantly reducing the noise as well as using a centrifugal blower that occupies less installation area The present invention relates to a wastewater purification device.

1 and 2, the conventional wastewater purification apparatus is connected to an air pump 1 for sucking and supplying external air and an air pipe 1a from the air pump 1; Consists of a purification tank (2) for aeration and purification of the waste water by the air supplied from the air pump (1) through the air pipe (1a),

The air pump unit 1 is a drive pulley 3 driven by a drive motor 3a, a blower pulley 5 connected to the V-belt 4 and interlocked with the drive pulley 3, and Roots blower (7) having an air intake (6) interlocked by the blower pulley (5) and suctions the outside air, and the air compressed in connection with the roots blower (7) to the purification tank (2) The main is composed of a discharge port 8.

Therefore, in the above-described conventional method, when the driving pulley 3 is driven by the driving motor 3a, the blower pulley 5 connected to the V-belt 4 is driven, and the blower pulley 5 is the roots blower 7. It rotates at high speed. By the high-speed rotation of the roots blower 7, air is repeatedly sucked, compressed and discharged to pressurize the air to the purification tank unit 2 through the discharge port 8.

By the way, as shown in FIG.

First, as the Roots blower 7 rotates at a high speed while the two rotors 7a rotated in opposite directions are rubbing, great noise is generated, and the two rotors 7a are also rubbed on the inner surface of the casing 7b. There is a problem that the noise is more weighted (80-90dB or more) because it is rotated,

Second, the bulky and heavy unit weight not only occupies a lot of installation area, but also has a problem that it is difficult to handle because of its heavy weight.

Third, the two rotors 7a rotated in opposite directions to each other are rubbed, and the two rotors 7a are also frictionally rotated with the inner surface of the casing 7b.

Fourth, there are many other wear and consumables (bearings, timing gears, etc.), and grease and oil management are many.

Fifth, there is a problem in safety management when replacing the worn parts such as the V-belt (4), the timing gear.

Accordingly, it is an object of the present invention to provide a wastewater purification apparatus using a centrifugal blower that significantly reduces intrinsic noise generated during operation of the air pump unit.

It is another object of the present invention to provide a wastewater purification apparatus using a centrifugal blower which can easily handle handling by lightly reducing the unit weight while significantly reducing the overall volume of the air pump unit.

Still another object of the present invention is to provide a wastewater purification apparatus using a centrifugal blower, which makes it easy to follow-up management by hardly generating heat during operation of the air pump unit.

Still another object of the present invention is to provide a wastewater purification apparatus using a centrifugal blower that is easy to manage grease and oil while reducing wear and consumables (bearings) of the air pump unit.

Still another object of the present invention is to provide a wastewater purification apparatus using a centrifugal blower, which can obtain a feeding effect without using parts having high abrasion, such as a V-belt or a timing gear.

Waste water purification apparatus using a centrifugal blower of the present invention for achieving the above object, the air pump unit for sucking and supplying external air, and connected to the air pipe from the air pump unit and the air pump through the air pipe A purifying tank portion for aerated and purifying waste water by air supplied from a portion, wherein the air pump portion has a cylindrical casing having an air inlet and an air outlet, filled with a certain amount of water in the casing, and A centrifugal rotor connected to an eccentric eccentric rod and rotated, a partition plate installed in the center of the centrifugal rotor and installed between the air intake port and the air discharge port, and a pressure plate installed in the center of the centrifugal rotor and opposite to the partition plate. It is configured as a basic technical idea of the present invention.

Hereinafter, the present invention will be described in more detail with reference to exemplary embodiments shown in the accompanying drawings.

3 to 5, the embodiment of the present invention, the air pump unit 10 for sucking and supplying external air, and the air pump 10 is connected to the air pipe 10a and the The air pump unit 10 is composed of a purification tank 20 for aeration and purification of the waste water by the air supplied from the air pump unit 10 through the air pipe 10a. A centrifugal rotor 12 which is connected to a cylindrical casing 11 having a predetermined amount of water seals and having an air inlet 11a and an air outlet 11b and an eccentric shaft rod 12a eccentric in the casing 11. And a partition plate 13 installed in the center of the centrifugal rotor 12 and installed between the air suction port 11a and the air discharge port 11b, and installed in the center of the centrifugal rotor 12. The pressure plate 14 installed on the opposite side of the From that point to implement the basic technical concept of the present invention.

Referring to the operation of the present invention configured as described above, as shown in Fig. 5, when the drive motor 12b is connected to the power supply in a state where about half of the water in the casing 11 is filled, the eccentric shaft 12a is provided. The combined centrifugal rotor 12 is rotated. As the centrifugal rotor 12 rotates at a high speed, centrifugal force is generated, and as shown in FIG. 6, the water in the casing 11 forms a water film 15 between the inner wall of the casing and the wing plate of the centrifugal rotor. .

At this time, the air in the center portion of the water film 15 is separated from the right portion p and the left portion q of the partition plate 13. When the air of the right part p sucked through the suction port 11a is transferred toward the pressure plate 14 by the rotation of the centrifugal rotor 12, the air is compressed and exits toward the discharge port 11b formed in the left part q. The operation is performed repeatedly.

The present invention is different from the conventional one in which the air is pumped to the aeration tank of the purification tank by using a Roots blower. The centrifugal blower is used to form a water film using centrifugal force and pressurizes the air to the purification tank unit 20 by the water film. Is applied.

On the other hand, as shown in Figure 3, one side is connected to the casing 11 and the other side is connected to the water tank 30 to add a water seal pipe 16 for supplying a certain amount of water at all times inside the casing (11) It is preferable to connect as a matter of course. Since a small amount of water is contained in the air discharged from the casing 11, it is necessary to continuously supply the water to maintain a constant amount of water in the casing 11 at all times.

At this time, the method of receiving the water can be supplied to the water tank 30, as well as directly connected to the water pipe can be supplied, and can also be used to connect the purified water in the purification tank unit 20.

As described above, the air pump unit 10 of the present invention uses noise centrifugal blower by using a centrifugal force, unlike the conventional one, which has a lot of problems such as noise and equipment by using a root blower, thereby significantly reducing noise (25 dB or less). Can reduce the installation volume and reduce the installation area while drastically reducing the overall volume and unit weight.Almost no heat resistance occurs during operation. It is easy to manage.
