Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment devices, and in particular to a sedimentation wastewater treatment device. Background Technology

[0002] Sedimentation wastewater treatment equipment is a device that removes suspended solids and sediments from wastewater through physical separation based on the principle of gravity sedimentation.

[0003] Existing sedimentation wastewater treatment devices typically transport wastewater to a sedimentation tank, where flocculants are added to aggregate solid impurities and allow them to settle. However, because the flocculants often fail to fully contact the wastewater after addition, some wastewater does not settle effectively, resulting in poor performance. Furthermore, after sedimentation, impurities are usually adsorbed by a sludge pump or discharged through pipes under gravity, which easily clogs the pipes, further hindering the device's effectiveness. Therefore, we propose a sedimentation wastewater treatment device. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a sedimentation-type wastewater treatment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sedimentation wastewater treatment device is designed, including a tank. An overflow hood is coaxially provided on the top of the tank. The bottom of the overflow hood is fixed to the outer side of the tank. A guide pipe is coaxially connected inside the tank. The bottom of the guide pipe is fixed to the inner wall of the tank by several support rods. Several sewage outlets are provided on the bottom side of the guide pipe. The top of the guide pipe is connected to one side of the overflow hood through a guide channel. An inlet is provided on the side of the overflow hood. The inlet is connected to the end of the guide channel. A top cover is installed on the top of the guide channel. A feed pipe is installed on one end of the top cover. Several rotating shafts are rotatably connected to both sides of the bottom of the feed pipe and the top cover. A guide plate is installed on the side of each rotating shaft.

[0006] The top cover has an installation cavity inside, and the top of each shaft extends into the installation cavity. A gear is installed on the top of each shaft. Two first connecting rods are symmetrically installed inside the installation cavity. The two first connecting rods are connected by several second connecting rods. A rack is installed on the side of each first connecting rod near the gear, and each rack meshes with the corresponding gear.

[0007] An eccentric wheel is rotatably connected inside the mounting cavity. The top of the eccentric wheel is connected to the first drive motor, and the first drive motor is fixed to the top of the top cover. A third link is rotatably connected to one side of the bottom of the eccentric wheel, and the other end of the third link is fixed to the side of one of the second links through a hinge seat.

[0008] Support legs are installed on the bottom edge of the tank. A conveying cylinder is connected between the support legs through a fixed seat. The conveying cylinder is inclined, and one end of the top of the conveying cylinder is connected to the bottom of the tank through a slag discharge pipe. A spiral extrusion rod is rotatably connected inside the conveying cylinder. One end of the spiral extrusion rod is connected to a second drive motor, which is fixed to the end of the conveying cylinder. A sewage discharge pipe is installed at the bottom of the other end of the conveying cylinder.

[0009] Preferably, the bottom of each second link is slidably connected to a guide groove formed at the bottom of the mounting cavity via a slider.

[0010] Preferably, the top edge of the tank has several overflow ports, and the bottom of the overflow ports is lower than the top of the overflow hood.

[0016] 1. The first drive motor can drive the eccentric wheel to rotate. The eccentric wheel can drive the second link to move back and forth through the third link, which in turn can drive the first link and the rack to move back and forth simultaneously.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-7 A sedimentation wastewater treatment device includes a tank 4. An overflow hood 1 is coaxially mounted on the top of the tank 4. The bottom of the overflow hood 1 is fixed to the outer side of the tank 4. A guide pipe 9 is coaxially connected inside the tank 4. The bottom of the guide pipe 9 is fixed to the inner wall of the tank 4 by several support rods. Several drain ports 26 are opened on the bottom side of the guide pipe 9. The top of the guide pipe 9 is connected to one side of the overflow hood 1 through a guide channel 8. An inlet 17 is opened on the side of the overflow hood 1 and is connected to the end of the guide channel 8. In actual use, such as... Figure 2 and Figure 7 As shown, wastewater can flow along the guide channel 8 through the inlet 17, flow into the guide pipe 9, and finally be discharged into the tank 4 through the outlet 26 for sedimentation treatment.

[0028] It should be noted that, as Figure 1 and Figure 2As shown, the top edge of the tank 4 is provided with several overflow ports 3. The bottom of the overflow port 3 is lower than the top of the overflow hood 1. A drain pipe 2 is installed on one side of the bottom of the overflow hood 1. The drain pipe 2 is lower than the bottom of the overflow port 3. In actual use, the settled water can pass through the overflow port 3 and be transported into the overflow hood 1, and finally discharged through the drain pipe 2.

[0029] It should be noted that the bottom of the overflow outlet 3 is lower than the bottom of the inlet 17, so that the overflow outlet 3 will not obstruct the sewage transported by the inlet 17.

[0030] like Figure 1 and Figure 3 As shown, a top cover 5 is installed on the top of the diversion channel 8. A feed pipe 7 is installed at one end of the top of the top cover 5. Several rotating shafts 19 are rotatably connected to both sides of the bottom of the feed pipe 7 and the top cover 5. A guide plate 10 is installed on the side of each rotating shaft 19. The flocculant can be transported into the diversion channel 8 through the feed pipe 7 and mixed with the sewage. This can adsorb and agglomerate the solid particles in the sewage, which is convenient for subsequent sedimentation.

[0031] like Figure 3 , Figure 4 and Figure 5 As shown, the top cover 5 has an internal mounting cavity 24. The top of each rotating shaft 19 extends into the mounting cavity 24, and a gear 20 is mounted on the top of each rotating shaft 19. Two first connecting rods 18 are symmetrically mounted inside the mounting cavity 24. The two first connecting rods 18 are connected by several second connecting rods 21. A rack 23 is mounted on the side of each first connecting rod 18 near the gear 20, and each rack 23 meshes with the corresponding gear 20. An eccentric wheel 25 is rotatably connected inside the mounting cavity 24. The top of the eccentric wheel 25 is connected to a first drive motor 6, and the first drive motor 6 is fixed to the top cover 5. At the top, a third link 22 is rotatably connected to one side of the bottom of the eccentric wheel 25. The other end of the third link 22 is fixed to the side of one of the second links 21 through a hinge seat. In actual use, the first drive motor 6 drives the eccentric wheel 25 to rotate. Under the action of the third link 22, the eccentric wheel 25 drives the second link 21 to move back and forth. In turn, the first link 18 drives the rack 23 to move back and forth. The rack 23 will drive the guide plate 10 to swing back and forth under the action of the gear 20. This can disturb the sewage flowing in the guide channel 8, so that the sewage can be fully mixed with the flocculant and improve the sedimentation effect.

[0032] like Figure 2 and Figure 6As shown, support legs 11 are installed on the bottom edge of the tank body 4. A conveying cylinder 14 is connected between the support legs 11 through a fixed seat 16. The conveying cylinder 14 is inclined, and one end of the top of the conveying cylinder 14 is connected to the bottom of the tank body 4 through a slag discharge pipe 12. A spiral extrusion rod 27 is rotatably connected inside the conveying cylinder 14. One end of the spiral extrusion rod 27 is connected to a second drive motor 13, which is fixed to the end of the conveying cylinder 14. A drain pipe 15 is installed at the bottom of the other end of the conveying cylinder 14. In actual use, the dirt that settles at the bottom of the tank body 4 will be transported to the conveying cylinder 14 along the slag discharge pipe 12. At this time, the second drive motor 13 works, driving the spiral extrusion rod 27 to work, which can transport the impurities that fall into the conveying cylinder 14 to the drain pipe 15 and finally discharge them through the drain pipe 15.

[0033] It should be noted that, as Figure 6 As shown, the pitch of the spiral extruder 27 decreases sequentially. When the spiral extruder 27 conveys impurities, it will squeeze the impurities and squeeze out the water in the impurities. In this way, the impurities discharged from the drain pipe 15 will remain dry, which is convenient for subsequent processing.

[0034] A discharge pipe 28 is installed at the bottom of the tank 4 away from the sewage pipe 15. A filter screen 29 is installed at the end of the discharge pipe 28 near the conveying cylinder 14. The discharge pipe 28 is controlled by a valve to open and close. After the sewage treatment is completed, the staff can open the valve and the water in the tank 4 can be discharged through the discharge pipe 28. The filter screen 29 can filter the impurities that are transported to the conveying cylinder 14 by the slag discharge pipe 12, preventing the impurities from being discharged through the discharge pipe 28.

[0035] Specifically, in use, the worker delivers wastewater through the guide channel 8 into the guide pipe 9. While the wastewater is being delivered, the worker also delivers flocculant through the feed pipe 7 into the guide channel 8. Then, the worker controls the first drive motor 6, which drives the eccentric wheel 25 to rotate. The eccentric wheel 25, via the third connecting rod 22, drives the second connecting rod 21 to reciprocate. The second connecting rod 21, via the first connecting rod 18, drives the gear 20 to oscillate reciprocally. Simultaneously, the gear 20, via the rotating shaft 19, drives the guide plate 10 to oscillate reciprocally. This allows the guide plate 10 to agitate the wastewater flowing within the guide channel 8, ensuring sufficient contact between the wastewater and the flocculant, thus improving the efficiency of the product. Afterwards, the sewage flows into the guide pipe 9 and is discharged into the tank 4 from the drain outlet 26. The sewage settles in the tank 4. After settling, the clean water at the top flows into the overflow hood 1 through the overflow outlet 3 and is discharged through the drain pipe 2. The settled impurities are transported into the conveying cylinder 14 through the slag discharge pipe 12. Then, the second drive motor 13 is controlled to work. The second drive motor 13 drives the spiral extrusion rod 27 to rotate, transporting the impurities falling into the conveying cylinder 14. During the transport process, the spiral extrusion rod 27 can squeeze the impurities, so that the water in the impurities is squeezed out. After drying, the impurities are discharged through the drain pipe 15, completing the impurity discharge without clogging and improving the use effect.

[0036] Furthermore, such as Figure 5 As shown, the bottom of each second link 21 is slidably connected to the guide groove opened at the bottom of the mounting cavity 24 by a slider. The cooperation between the slider and the guide groove can limit the second link 21, so that the second link 21 and the rack 23 remain stable.

[0037] Furthermore, such as Figure 5 As shown, there is a gap between the two ends of the first connecting rod 18 and the end of the mounting cavity 24, so that the first connecting rod 18 will not collide with the inner wall of the mounting cavity 24 during the reciprocating movement following the rotation of the eccentric wheel 25, thus improving the performance.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
