Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, in particular to an activated carbon adsorption device for sewage treatment. Background Art

[0002] As a low-cost adsorbent with large surface area and strong adsorption capacity, activated carbon is currently widely used in the deep treatment of urban sewage, industrial wastewater and purification of polluted water sources.

[0003] The invention patent with application number CN201910392879.1 discloses a rotary filtering equipment based on activated carbon. A feed pipe is connected to the middle of the top of the hollow cylinder. A first bearing seat is embedded in the center position of the front and rear sides of the hollow cylinder. A first rotating shaft is connected between the first bearing seats on the front and rear sides. A plurality of mesh plates are evenly spaced and installed in the middle of the first rotating shaft. A groove is opened in the middle of the outer side of the mesh plate, and plate-shaped activated carbon is arranged in the groove. A first opening for removing the plate-shaped activated carbon is opened in the upper left part of the hollow cylinder. A second opening for passing debris is opened in the middle of the right side of the hollow cylinder. An arc-shaped limit rod that can block the plate-shaped activated carbon is fixed between the left side of the top and the left side of the bottom of the second opening. A discharge pipe for discharging debris is installed in the middle of the outer right side of the hollow cylinder. A discharge pipe for discharging sewage is connected to the left side of the bottom of the hollow cylinder. A driving device that can rotate the mesh plate forward is provided between the discharge pipe and the rear end of the first rotating shaft. By connecting the feed pipe and the sewage discharge pipe together, when the sewage is discharged into the hollow cylinder, the mesh plate filters the debris in the sewage. At the same time, the plate-shaped active plate can adsorb heavy metal ions in the sewage. The filtered sewage is discharged through the discharge pipe. At the same time, the forward rotation of the mesh plate can discharge the debris through the discharge pipe, avoiding the accumulation of debris affecting the discharge of sewage.

[0004] However, the above-mentioned filtering equipment adopts the method of water inlet from above and water outlet from below. When the sewage is discharged into the hollow cylinder through the feed pipe, it is easy to cause part of the sewage to splash into the discharge pipe, thereby causing part of the sewage to be discharged together with the debris, reducing the efficiency of sewage treatment.

[0011] As a further improvement, multiple groups of partition components are evenly spaced around the axis in the mesh cage, and each group of partition components includes two mesh plates, which are fixedly installed between the outer wall of the barrel and the inner wall of the mesh cage. The outer wall of the barrel, the inner wall of the mesh cage and the two mesh plates form a filling chamber, and the activated carbon filler is arranged in multiple filling chambers.

[0012] As a further improvement, one end of the barrel is a closed end, and the other end of the barrel is provided with an openable cover.

[0017] The present invention drives the barrel to rotate by a driving motor, which drives the mesh cage and scraper to rotate, and then the scraper drives the debris entering the shell to rotate.

DETAILED DESCRIPTION

[0027] like Figures 1 to 5 As shown, an activated carbon adsorption device for sewage treatment includes a base 1, a hollow cylindrical shell 2 is provided on the base 1, the axis of the shell 2 extends horizontally, a cylindrical barrel 3 is coaxially mounted on the shell 2, mounting holes are respectively provided at both ends of the shell 2, the barrel 3 is rotatably mounted in the mounting holes through bearings, a sealing ring is provided between the inner wall of the mounting hole and the barrel 3, a cylindrical mesh cage 4 is coaxially fixedly mounted on the barrel 3 located in the shell 2, the mesh cage 4 is welded to the outer wall of the barrel 3, the axial length of the mesh cage 4 is consistent with the axial length inside the shell 2, and an activated carbon filler is provided in the mesh cage 4. 5. A plurality of scrapers 6 extending along the axial direction of the shell 2 are evenly spaced around the axis on the outside of the mesh cage 4. The scrapers 6 are welded to the mesh cage 4. The side of the scraper 6 away from the mesh cage 4 and both ends of the scraper 6 are in contact with the inner wall of the shell 2. A discharge pipe 7 extending horizontally along its tangential direction is welded to one side of the top of the shell 2. A discharge port 8 connected to the discharge pipe 7 is provided on the shell 2. A drive motor 9 for driving the barrel 3 to rotate is installed on the base 1. A water inlet pipe 10 is provided at the bottom of the shell 2. A water outlet pipe 11 is also provided on the shell 2. The height of the water outlet pipe 11 is located between the water inlet pipe 10 and the discharge pipe 7.

[0028] During use, sewage is injected into the housing 2 through the water inlet pipe 10. After the sewage level rises, it passes upward through the mesh cage 4 and is discharged from the outlet pipe 11. During this process, the activated carbon filler 5 inside the mesh cage 4 adsorbs harmful substances in the sewage. The side walls of the mesh cage 4 are provided with mesh, which prevents larger debris in the sewage from passing through the mesh, causing the debris to be trapped between two adjacent scrapers 6. The drive motor 9 drives the barrel 3 to rotate, which in turn drives the mesh cage 4 and scrapers 6. The scrapers 6 then drive the debris that has entered the housing 2. When the scrapers 6 drive the debris to the discharge port 8, the debris is thrown into the discharge pipe 7 under the action of centrifugal force, thus preventing large amounts of debris from accumulating in the housing 2 and clogging the pipe.

[0029] Since the water injection method of water inlet at the bottom and water outlet at the top is adopted, it can prevent sewage from splashing around when injected into the shell 2, and the height of the discharge pipe 7 is higher than the height of the outlet pipe 11, thereby preventing sewage from being discharged from the discharge pipe 7 along with debris.

[0030] In order to reduce the resistance to the rotation of the barrel 3, a plurality of water-permeable holes are evenly distributed on the scraper 6.

[0031] In order to prevent debris from being thrown out to the outside of the discharge pipe 7, a closing plate is fixedly installed at the end of the discharge pipe away from the shell 2 by bolts. In order to facilitate the cleaning of debris in the discharge pipe 7, a discharge port 12 is provided at the bottom of the discharge pipe 7, and a collection trough 13 connected to the bottom of the discharge port 12 is installed at the bottom of the discharge pipe 7 by bolts.

[0032] Since the debris thrown into the discharge pipe 7 will carry a small amount of water, in order to further prevent sewage from being discharged from the discharge pipe 7 along with the debris, a return hole 14 is provided on the shell 2 to connect the discharge pipe 7 and the inner cavity of the shell 2. The height of the return hole 14 is lower than the height of the bottom of the discharge port 8.

[0033] like Figure 3 and Figure 4 As shown, both ends of the barrel 3 extend to the outside of the shell 2, a motor bracket 15 is fixedly installed on the base 1 by bolts, and a drive motor 9 is installed on the top of the motor bracket 15 by bolts. A driving gear 16 is fixedly installed on the rotating shaft of the drive motor 9, and a passive gear 17 meshing with the driving gear 16 is fixedly installed at one end of the barrel 3. When the drive motor 9 is working, it drives the driving gear 16 to rotate, and then the driving gear 16 drives the passive gear 17 and the barrel 3 to rotate.

[0034] like Figure 2As shown, in order to evenly distribute the activated carbon filler 5 within the mesh cage 4 and intensify the reaction between the activated carbon filler 5 and the sewage, multiple groups of partitioning components are evenly spaced around the axis of the mesh cage 4. Each group of partitioning components includes two mesh plates 18, which are welded between the outer wall of the barrel 3 and the inner wall of the mesh cage 4. The outer wall of the barrel 3, the inner wall of the mesh cage 4, and the two mesh plates 18 enclose a packing chamber 19, in which the activated carbon filler 5 is disposed. As the mesh cage 4 rotates, it drives the activated carbon filler 5 within the packing chamber 19 to rotate with it, thereby preventing the activated carbon filler from clumping. At the same time, the activated carbon filler 5 and the mesh cage 4 stir the sewage to a certain extent, thereby improving the activated carbon filler 5's efficiency in absorbing harmful substances in the sewage.

[0035] like Figure 3 As shown, to facilitate the filling and replacement of the activated carbon filler 5, one end of the barrel 3 is closed, and the other end of the barrel 3 is provided with an openable cover 20. One end of the cover 20 is hinged to the barrel 3 via a hinge 21. A handwheel 22 is hinged on the side of the barrel 3 opposite the hinge 21 for tightening the cover 20. After loosening the handwheel 22, the cover 20 can be rotated about the hinge 21 to open. A through opening 23 communicating with the filling chamber 19 is provided on the side wall of the barrel 3. A retaining plate 24 is rotatably mounted within the barrel 3 for closing the multiple through openings 23. The retaining plate 24 is arc-shaped and has an opening 25 on one side. The angle of the opening 25 is smaller than the angle between two adjacent through openings 23.

[0036] Specifically, when filling the activated carbon filler 5 into the filling chamber 19, the cover 20 is opened, the barrel 3 is rotated so that one of the filling chambers 19 is rotated to the bottom of the barrel 3, and the baffle plate 24 is rotated so that the opening 25 is aligned with the through-port 23 of the filling chamber 19, as shown in FIG. Figure 2 As shown, the activated carbon filler 5 can then be conveniently filled into the filling chamber 19 located at the bottom of the barrel 3; after multiple filling chambers 19 are filled in accordance with this method, the baffle plate 24 is rotated to rotate the opening 25 to between the two through-ports 23, so that the through-ports 23 of the multiple filling chambers 19 are all closed, thereby preventing the activated carbon filler 5 in the filling chamber 19 from spilling out when the barrel 3 is rotated.

[0037] Or when replacing the activated carbon filler 5, after opening the cover 20, rotate the barrel 3 so that one of the filling chambers 19 is rotated to the top of the barrel 3, and rotate the baffle plate 24 so that the opening 25 is aligned with the through-port 23 of this filling chamber 19. Then, the activated carbon filler 5 in the filling chamber 19 at the top of the barrel 3 can be poured into the barrel 3 through the through-port 23 and the opening 25. The staff cleans and removes the activated carbon filler 5 in the barrel 3, and then refills the activated carbon filler 5 into the filling chamber 19.

[0038] In order to facilitate the rotation and adjustment of the baffle plate 24, a connecting plate 26 is fixedly installed inside the baffle plate 24 by bolts, and an adjusting shaft 27 coaxially arranged with the barrel 3 is welded on the connecting plate 26. One end of the adjusting shaft 27 extends to the outside of the barrel 3 and is fixedly installed with a rotating wheel 28. The adjusting shaft 27 is connected to the side wall of the closed end of the barrel 3 through a sealed bearing.

[0039] In order to prevent the baffle plate 24 from rotating freely in the barrel 3, as shown in FIG. Figure 3 and Figure 5 As shown, a threaded tube 29 is welded to the runner 28, and a threaded rod 30 extending axially along the shell 2 is screwed into the threaded tube 29. A plurality of positioning grooves 31 for inserting one end of the threaded rod 30 are evenly spaced around the axis on the outside of the closed end of the barrel 3. Specifically, when filling the activated carbon filler 5 into the filling chamber 19 or replacing the activated carbon filler 5, the threaded rod 30 is rotated in a specific direction so that its end is disengaged from the positioning groove 31, thereby releasing the restriction on the rotation of the baffle plate 24; or after the activated carbon filler 5 is filled, the baffle plate 24 is rotated so that the opening 25 is rotated to between the two through ports 23, and then the threaded rod 30 is rotated in the opposite direction so that its end is inserted into the aligned positioning groove 31, thereby restricting the rotation of the baffle plate 24 in the barrel 3.

[0040] In order to conveniently pour out the activated carbon filler 5 that has fallen into the barrel 3, Figure 4 As shown, a support rod is welded to the base 1, and one end of the shell 2 is rotatably mounted on the support rod via a horizontally extending mounting shaft 32. The axis of the shell 2 is perpendicular to the axis of the mounting shaft 32. A hydraulic cylinder 33 is hinged between the shell 2 and the base 1 for adjusting the tilt angle of the shell 2. Specifically, during the sewage treatment process, the tilt angle of the shell 2 is adjusted by telescoping the hydraulic cylinder 33 to keep the shell 2 in a horizontal state, thereby improving the stability of the shell 2. Alternatively, when replacing the activated carbon filler 5, when the activated carbon filler 5 in the filling chamber 19 at the top of the barrel 3 is poured into the barrel 3, the tilt angle of the shell 2 is adjusted by telescoping the hydraulic cylinder 33 to tilt and lower the end of the barrel 3 provided with the cover plate 20, so as to facilitate pouring out the activated carbon filler 5 in the barrel 3.
