Description

Technical Field

[0001] This utility model relates to the field of rainwater treatment technology, specifically to an activated carbon rainwater treatment device with filtration function. Background Technology

[0002] Activated carbon is mainly responsible for removing dissolved organic matter, odors and some chemical pollutants from pretreated rainwater in rainwater treatment. Activated carbon is usually used in rainwater reuse systems with high requirements for effluent quality.

[0003] Although rainwater undergoes pretreatment before being treated with activated carbon, impurities or particles may still be present in the rainwater during pretreatment due to the process. Currently, rainwater treatment devices have a relatively simple structure, directly connecting the inlet pipe to the inside of the tank where it contacts the activated carbon. This structure is not suitable for filtration, and the concentrated contact points with the activated carbon may result in poor adsorption. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Summary of the Invention

[0004] The purpose of this invention is to provide an activated carbon rainwater treatment device with a filtration function to solve the problems mentioned in the background art.

The tank body has a tank cover at its top, and a first manhole is provided on the upper surface of the tank cover. The water distribution plate is conical and has a connecting sleeve at its bottom. The water distribution board has a central hole at its center, and the connecting sleeve is connected to the central hole of the water distribution board. The bottom of the tank cover has a water distribution board, and the upper surface of the water distribution board has a conical perforated plate. The upper surface of the conical perforated plate has an annular baffle. The sidewalls and annular baffles of the conical perforated plate... The baffles are densely covered with sieve holes. The water distribution plate is located inside the tank cover and directly above the conical perforated plate. The water distribution plate is located around the conical perforated plate and is densely covered with water distribution holes. A water inlet pipe is provided on one side of the upper part of the tank. The inner end of the water inlet pipe is located inside the tank and is provided with a bend. An extension section is provided at the top of the bend. The extension section passes through the central hole of the water distribution plate and is inserted into the connecting sleeve. A planar perforated plate is provided inside the tank through a support rod. The planar perforated plate is densely covered with single-headed tubular water caps. A second manhole is provided at the bottom of the tank. The second manhole is connected to a sealing plate. The sealing plate is connected to a water outlet.

[0007] Preferably, the present invention provides an activated carbon rainwater treatment device with a filtration function, wherein activated carbon is supported inside the tank and on the upper surface of the planar perforated plate.

[0008] Preferably, the activated carbon rainwater treatment device with filtration function provided by this utility model has a plurality of reinforcing limiting rods arranged inside the tank perpendicular to the direction of the water inlet pipe, and the reinforcing limiting rods respectively abut against the surface of the bend and the water inlet pipe.

[0009] Preferably, the activated carbon rainwater treatment device with filtration function provided by this utility model is provided with an vent and a lifting lug on the upper surface of the tank cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are: A water distribution plate is installed at the bottom of the tank lid, and a conical perforated plate is installed on the upper surface of the water distribution plate. A water distribution disc is installed at the center of the water distribution plate through a connecting sleeve. The connecting sleeve is connected to the extension section of the bend. When water is introduced, the water first overflows through the water distribution disc into the conical perforated plate. It is first screened through the sieve holes of the conical perforated plate, so that impurities and particles are retained in the conical perforated plate. The filtered water flows onto the water distribution plate and drips evenly onto the activated carbon through the water distribution holes. Firstly, the filtration avoids too many impurities from affecting the treatment effect of the activated carbon. Secondly, the water distribution plate can make the water fall evenly on the activated carbon, thereby improving the adsorption effect of the activated carbon. At the same time, the conical perforated plate can trap impurities and facilitate cleaning through the first manhole. Attached Figure Description

[0017] Installation method and operating principle: First, pass the inlet pipe 11 through the side wall of the tank 1 and weld it to the tank 1. Then, weld one end of the bend 12 to the inside of the inlet pipe 11, with the extension section 13 of the bend 12 facing upwards. At the same time, weld multiple reinforcing limiting rods 23 horizontally inside the tank 1 and press them onto the upper and lower ends of the bend 12 and the inlet pipe 11. Next, weld the flat perforated plate 5 with a single-headed tubular water cap 15 to the inside of the tank 1 using support rods. Then, install the sealing plate 17 with the outlet 18 at the second manhole 16 with bolts, completing the installation of the tank 1 and its internal components. Weld the connecting sleeve 7 of the water distribution plate 3 to the through hole at the center of the water distribution plate 4. A conical perforated plate 8 is also welded to the upper surface of the water distribution plate 4 and coaxial with the water distribution plate 3. An annular baffle 9 is provided at the top of the conical perforated plate. The side wall of the conical perforated plate 8 and the annular baffle 9 are densely covered with screen holes. Next, the outer extension of the water distribution plate 4 is welded to the bottom of the tank cover 2, completing the installation of the tank cover 2 and internal components. Finally, the tank cover 2 is hoisted onto the tank body 1, and the connecting sleeve 7 is connected to the extension section 13 of the bent pipe 12. The tank cover 2 is then pressed down to connect it to the upper part of the tank body 1. Finally, the tank cover 2 is welded to the tank body 1 to complete the installation. Before use, activated carbon 22 is added into the tank body 1 through the feeding port 19 and supported on the flat perforated plate 5. During use, rainwater enters from the inlet pipe 11 and overflows from the water distribution plate 3 into the conical perforated plate 8. Through the sieve holes of the conical perforated plate 8, the water flows through the sieve holes onto the water distribution plate 4. Particulate impurities remain in the conical perforated plate 8. Then, the water falls evenly onto the activated carbon 22 through the water distribution holes 10 of the water distribution plate 4. After being adsorbed by the activated carbon 22, it is discharged from the outlet 18 at the bottom of the tank body 1. When there are too many impurities in the conical perforated plate 8, it can be cleaned through the first manhole 6. This utility model has a reasonable structure. A water distribution plate 4 is provided at the bottom of the tank cover 2. A conical perforated plate 8 is provided on the upper surface of the water distribution plate 4. A water distribution disk 3 is provided at the center of the water distribution plate 4 through a connecting sleeve 7. The connecting sleeve 7 is connected to the extension section 13 of the bend 12. When water is introduced, the water first overflows into the conical perforated plate 8 through the water distribution disk 3. It is then sieved through the sieve holes of the conical perforated plate 8, so that impurities and particles are left in the conical perforated plate 8. The filtered water flows onto the water distribution plate 4 and drips evenly onto the activated carbon 22 through the water distribution holes 10. First, the filtration avoids too many impurities from affecting the treatment effect of the activated carbon 22. Second, the water distribution plate 4 allows the water to fall evenly onto the activated carbon 22, thereby improving the adsorption effect of the activated carbon 22. At the same time, the conical perforated plate 8 can trap impurities and facilitate cleaning through the first manhole 6.
