Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an integrated urban wastewater treatment device. Background Technology

[0002] Urban sewage contains a mixture of various types of garbage and wastewater. The sewage contains suspended particulate matter, and direct discharge of such wastewater causes environmental pollution. Furthermore, drainage pipes can be blocked by garbage, affecting continuous drainage. However, integrated wastewater treatment devices cannot intercept and filter discharged wastewater. During continuous filtration, the filter screen becomes clogged with debris, affecting continuous interception and filtration. It is inconvenient to perform shaking interception and filtration, and it does not have the combination of multi-layer sedimentation filtration and multi-layer adsorption filtration to reduce particulate matter and suspended solids in wastewater.

[0005] Furthermore, the interior of the sedimentation tank is connected to the interior of the interception tank, and the bottom of the interception tank is provided with an inclined guide plate, with the left end of the guide plate being higher than the right end.

[0006] In this invention, the guide plate helps to initially intercept the falling sewage and guide it into the sedimentation tank.

[0007] Specifically, the top left end of the interception box is provided with a support plate, the middle of the support plate is provided with a receiving hopper, the end of the receiving hopper extends into the interception box, and the right end face of the interception box is welded and fixed to the left end face of the sedimentation box.

[0008] In this invention, with the help of the receiving bucket, urban sewage drawn from the outside is easily guided into the middle position of the interception component, and the support plate provides stability for the installation of the receiving bucket.

[0009] It should be noted that the partition plate evenly distributes the contents inside the sedimentation tank. A first filter screen is provided in the middle of the partition plate, and a second filter screen is provided in the middle of the right end face of the sedimentation tank. Slag discharge pipes are symmetrically provided near the bottom of the front end face of the sedimentation tank. The slag discharge pipes are connected to the interior of the compartments separated by the partition plate, and valves are provided at the ends of the slag discharge pipes.

[0010] In this invention, the partition plate divides the interior into two sedimentation chambers. The first filter screen initially intercepts and filters the sedimented wastewater, and the second filter screen intercepts and filters the secondary sedimented wastewater again. Opening the valves on the two sludge discharge pipes helps to discharge and clean the sediment in the corresponding chambers.

[0011] Furthermore, the right end face of the sedimentation tank is tightly attached to and bonded to the left end face of the filter box. The filter box is symmetrically provided with several sets of slide rails, each set having two slide rails. Each slide rail has a groove on its opposite side. An insert plate is provided between the two slide rails, and filter cotton is provided in each insert plate.

[0012] In this invention, the three sets of corresponding slide rails facilitate the corresponding insertion and cooperation of the three insert plates. Each insert plate has a slider at both ends, which is inserted and cooperates with the slide groove. The filter cotton is fixedly connected to the insert plate by screws. The mesh density of the three corresponding filter cotton gradually increases from left to right, which helps to adsorb and filter the settled sewage, reduce the impact of suspended solids on environmental pollution and pipe blockage.

[0013] Secondly, a drain pipe is provided at the bottom of the right end face of the filter box, and a butterfly valve is provided at the end of the drain pipe.

[0017] Furthermore, the convex shaft and the eccentric wheel are integrally formed structures, and the two ends of the connecting shaft are respectively welded and fixed to the corresponding convex shafts. One end of the connecting rod is rotatably connected to the convex shaft, and the other end is rotatably connected to the hinge seat. The top of the hinge seat is welded and fixed to the bottom of the tray.

[0018] In this invention, the connecting shaft enables the two convex shafts to rotate synchronously, and the connecting rod connects the convex shafts to the hinge seat, so that the rotation of the eccentric wheel drives the right end of the tray to reciprocate up and down around the left end.

[0019] In addition, the tray is welded and fixed to the connecting plate, the connecting plate is rotatably connected to the rotating shaft seat, the width of the inner wall of the tray is adapted to the width of the outer wall of the interception box, the top of the interception box is symmetrically provided with a pull handle, the outer wall of the interception box is provided with a screw hole near the top, the screw hole is provided with a fastening bolt, and the outer wall of the tray is provided with a through hole corresponding to the screw hole.

[0020] In this invention, the through slots are evenly spaced to facilitate drainage through the interceptor box. The two pull handles provide leverage points, which helps to remove the interceptor box for replacement or cleaning. The filter holes are evenly spaced to help separate internal sewage from large particles of garbage. The fastening bolts pass through the through holes and are threaded into the corresponding screw holes to achieve the combination and fixation of the interceptor box and the tray.

[0021] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model guides the wastewater initially intercepted by the interception component into the sedimentation tank by setting a guide plate. The partition plate divides the inside of the sedimentation tank into two sedimentation chambers, with multiple layers of sedimentation. With the cooperation of the first and second filter screens, the sedimented wastewater is filtered and enters the filter box. With the cooperation of three insert plates with filter cotton, multi-layer adsorption filtration is achieved. The motor provides power, and the rotation of the eccentric wheel drives the tray to continuously shake up and down around the rotating shaft seat, shaking and intercepting the wastewater mixture in the interception box, reducing the impact of clogging of the filter holes on continuous interception.

[0022] 2. This utility model, by setting a support plate with a receiving hopper, guides external urban sewage into the interception box from the top. The interception box is fixed to the tray with fastening bolts, increasing the stability of the assembly. The fastening bolts can be removed, and the interception box can be easily taken out for replacement or cleaning with the help of a pull handle.

The filter holes 410 are evenly spaced to help separate internal sewage from large particles of garbage. The fastening bolts 413 pass through the through holes 402 and are threadedly connected to the corresponding screw holes 412 to realize the combination and fixation of the interception box 41 and the tray 40.

[0038] It is worth adding that the drive assembly 5 includes a motor 50 and two eccentric wheels 51 coaxially connected to the output shaft of the motor 50. The eccentric wheels 51 are rotatably connected to the interception box 1 through a rotating shaft. A convex shaft 510 is provided near the edge on the opposite side of the eccentric wheels 51. A connecting shaft 511 is provided between the two convex shafts 510. A connecting rod 52 is sleeved on each of the convex shafts 510.

[0039] Furthermore, the motor 50 is fixedly connected to the interception box 1 by screws, and the output shaft of the motor 50 is fixedly connected to the shaft of one of the eccentric wheels 51 through a coupling. The eccentric wheels 51 are all rotatably connected to the interception box 1 through shafts.

[0040] In this utility model, the motor 50 is electrically connected to an external power source through a wire, and the control switch on the outer wall of the motor 50 controls the rotation of the output shaft of the motor 50. The tray 40 in the interception assembly 4 rotates to provide power. With the cooperation of the eccentric wheel 51, the tray 40 moves up and down around the eccentric wheel 51 to perform shaking interception and water filtration.

[0041] Furthermore, the cam shaft 510 and the eccentric wheel 51 are integrally formed structures.

One end of the connecting rod 52 is rotatably connected to the cam shaft 510, and the other end is rotatably connected to the hinge seat 403. The top of the hinge seat 403 is welded and fixed to the bottom of the tray 40.

[0042] In this utility model, the connecting shaft 511 enables the two convex shafts 510 to rotate synchronously, and the connecting rod 52 connects the convex shafts 510 and the hinge seat 403, so that the rotation of the eccentric wheel 51 drives the right end of the tray 40 to reciprocate up and down around the left end.

[0043] In this embodiment of the integrated urban sewage treatment device, when in use, the sedimentation tank 2 with partition plate 20 and the interception tank 1 with guide plate 10 are first combined and fixed.

Urban sewage first enters the interception box 41 above the interception box 1 from the receiving hopper 120. The control switch on the outer wall of the motor 50 is turned on, and the output shaft rotates, driving the two eccentric wheels 51 to rotate synchronously. With the cooperation of the connecting rod 52, the tray 40 continuously shakes up and down around the rotating shaft seat 11. The sewage is shaken and filtered in the interception box 41, initially intercepting large particles and large pieces of garbage. Then, under the action of gravity, the sewage enters the sedimentation box 2 from the guide plate 10. The left compartment of the partition plate 20 undergoes initial sedimentation. Then, with the cooperation of the first filter screen 200, the sedimented sewage enters the right compartment of the partition plate 20 for secondary sedimentation. With the cooperation of the second filter screen 21, it enters the filter box 3. The three insert plates 32 with filter cotton 320 sequentially adsorb and filter the sewage after multiple layers of sedimentation, adsorbing suspended solids and small particles. Finally, it is discharged from the drain pipe 31. When the interceptor box 41 needs to be cleaned or replaced, the fastening bolt 413 is removed, and with the help of the pull handle 411, the interceptor box 41 can be taken out for cleaning. The multiple insert plates 32 can be easily taken out for cleaning, which helps to continuously filter. The sediment in the sedimentation tank 2 is discharged from the corresponding slag discharge pipe 22, which is convenient for the next sedimentation.
