Description

Wastewater Float Separation and Transfer Device

The present invention relates to a wastewater floatation separation and transport apparatus for filtering and separating and transporting insoluble suspended solids contained in the wastewater installed in a float collecting well of a sewage treatment plant sedimentation basin.

In general, a feeder using a continuous operation microbar screen (MICRO-BAR SCREEN) was used to remove suspended solids contained in wastewater by being installed in a sump of sewage treatment plant sedimentation basin. As shown in Fig. 4, the rake 41, which is driven by being engaged with the chain 42 geared to the chain gear 43, jumps out from the back of the screen 40 to the front and scrapes off the suspended material on the screen. It was operated in a configuration to separate and transport the float in the process of rotating to the rear to go up.

However, the conventional wastewater floating matter separation and transport apparatus as described above is limited to the length of the rake 41 protruding to the upper surface of the screen, and this is insufficient in the case of a large amount of suspended solids. In addition, there was a problem that the scraping off the floating matters fall off and fall back to the waste water, the efficiency of removing the floating matters.

In addition, in order to transfer the removed suspended matter to the garbage vehicle, an expensive microbar screen must be installed from the lower part to the upper part of the float remover, and the upper part of the screen must be bent in a semicircular shape to make the device complicated and equipment costs. There were a number of problems, such as the need for a lot.

The present invention has been devised in view of the above problems, and provides a wastewater floatation separation and transport apparatus that can be efficiently removed regardless of the amount and transport height of the float by connecting the transport conveyor to the continuous operation type microbar screen. The purpose.

In addition, another object of the present invention is to provide a waste water floatation separation and transport device to reduce the installation cost by shortening the installation length of the screen.

A chain 324 'geared to the chain gears 325' and 325 &quot;, which are rotated and received by the driving force of the motor 326, is coaxially compressed with the chain gear 325 " A chain gear 324 geared to the chain gear 323 'located at the upper end of the upper body) and a chain gear 323 "located at the lower end of the frame, and a scraper 321 fastened to the chain at a predetermined interval; A chain gear 323 adapted to receive rotational force at an appropriate position between the chain gears 323 'and 323 ", an electric gear 322 coaxially condensed with the chain gear, and the screen 31 A driving unit 32 connected to one end and comprising a support plate 328 extending to an upper portion of the base 327;

An electric gear 332 which meshes with the electric gear 322 and rotates, a chain gear 333 'coaxially condensed with this electric gear, a chain gear 333 "paired with the electric gear 333, and the chain gear 333 And a rake portion 33 composed of a chain 334 geared to the 333 &quot; and a rake 331 fixed at a predetermined interval to the chain.

The screen 31 is a filter body which is installed to be inclined at approximately 60 ° in the waterway in a length proportional to the depth of the waterway so that the suspended matter contained in the waste water is caught by the bars 311. As shown in FIG. A plurality of bars 311 having a cross section are arranged to have a predetermined gap 312.

The driving unit 32 is to rotate and drive the rake 331 and the scraper 321 installed to remove the suspended matter on the screen 31, the chain gear 325 'rotated by receiving the power of the motor 326. A chain 324 'geared to a 325 &quot; and a chain gear 323' and a chain gear 323 &quot; which are rotated by the chain gear 325 " and constitute the same inclination as the screen 31. The chain 324 which is gear-coupled, the chain gear 323 located between the chain gears 323 'and 323 ", and are coaxially coaxial with this chain gear, transmit a rotational force to the rake part 33. And a support plate 328 connected to one end of the screen 31 and positioned at the bottom of the base 327 and extending up to the top thereof, and positioned at the top of the support plate and opened at the bottom thereof. It is comprised by the opening 329 which discharges a float to the garbage vehicle B. FIG.

Rake portion 33 is for scraping off the suspended matter in the gap 312 of the bar, as shown in Figure 3, with a predetermined interval on the support bar 335 so that each one can be inserted into the gap 312. It has a plurality of rakes 331 installed, the rake is engaged to the chain gear 334 geared by the chain gear (333 ') (333 ") is rotated in engagement with the electric gear 322 of the drive ( Rotation is driven by 332, and the bottom surface is supported by the scraper 321 during the driving.

That is, the rake 331 arranged horizontally by the number of the gap and the scraper 321 for supporting the rake in the same number to fit in the gap 312, respectively, and scrapes the foreign material scratched by the rake 321 is to be supported so as not to be separated to the outside to be transported to the top.

If described in detail the operation of the wastewater floating water separation and transport apparatus according to an embodiment of the present invention configured as described above.

When the waste water flows in through the inlet 10 and the motor 326 is operated at the same time, the electric gears 322 and 332 and the chain gears 325, 335 ', 323, 323' and 323 "( 333 ') and 333 "are operated and the chains 324, 324' and 334, and the scraper 321 and the rake 331 coupled thereto rotate.

That is, as shown in FIG. 3, when the rake 331 is lifted upward by the chain 334 and scrapes up the float inserted in the screen 31, the float supports the bottom of one side of the rake 331. 321 is collected in the case 327 to be collected in a separate garbage vehicle (B) or the trash box.

At this time, even if the rake 331 is raised and rotated in the circular direction by the chain 334, the scraper 321 can continue to convey the float in the state in contact with the inclined inner surface of the case 327.

Thus, the suspended matter introduced through the inlet 10 is filtered by the gap 312 of the screen and scraped by the rake 331 and then lifted upward by the scraper 321 to be discharged to the outside, and the treated wastewater is drained. It flows out through the 20.

Therefore, the present invention is less expensive to install by installing a certain length of the screen only in the bottom of the float separation eliminator, compared to the conventional device which is expensive to install the expensive screen from the bottom to the top of the float separation transporter, the conventional float While the float is limited by removing the float by supporting the short length of the rake, the present invention removes the float attached to the screen by the rake and the scraped float is supported by the scraper 321 to be transported upward. There is an advantage that can be efficiently removed even if the suspended matter is stuck on the screen (31).

In addition, there is an advantage that can be easily solved by extending the chain length and the backing plate length of the drive unit even when the distance from the sump of the waste water treatment plant settling basin to the garbage vehicle or the trash box is far.

Thus, the float separation and conveying apparatus of the present invention has a screen 31 having a length proportional to the depth of the channel, a rake 331 fitted to the screen to remove the float, and a scraper 321 supporting the rake. 331 and the driving unit 32 for rotating the scraper 321, there is an effect that can efficiently separate and transport the suspended matter contained in the waste water and reduce the installation cost of the device.
