[0002] A vertical flow sedimentation tank for factory sewage discharge is a device used to treat industrial wastewater, mainly for removing suspended solids, sediments and some organic matters in the wastewater. In industrial production, wastewater treatment is an important link, because discharging untreated wastewater directly into the environment will cause serious pollution to water bodies, soil and the ecological environment. Therefore, factories need to adopt effective wastewater treatment technologies to reduce pollutant emissions and protect the environment. After the existing vertical flow sedimentation tank sinks and filters large particle impurities in the sewage, there are still a small amount of suspended impurities floating in the overflow weir following the refluxing supernatant. Since the overflow weir is usually fixedly connected to the inner wall of the cylinder body, and the top of the overflow weir is multiple cones, it is more troublesome for users to clean the suspended impurities inside it, and it is easy to cause scratches.

The water inlet pipe 2 is fixedly installed on the front side of the surface of the cylinder body 1. One end of the water inlet pipe 2 close to the cylinder body 1 is communicated with one end of the connecting pipe 3 far from the overflow weir 7. The other end of the connecting pipe 3 is located inside the flow stabilizing pipe 8. The water outlet pipe 4 is fixedly installed on the top of the right side of the surface of the cylinder body 1. The sewage collecting funnel 5 is located at the bottom of the flow stabilizing pipe 8. The sewage discharge pipe 6 is fixedly installed at the bottom of the cylinder body 1. The sewage discharge pipe 6 is communicated with the sewage collecting funnel 5. The surface of the overflow weir 7 is movably connected with the top of the inner wall surface of the cylinder body 1. The surface of the flow stabilizing pipe 8 is fixedly connected with the inner wall of the overflow weir 7. The inner wall of the cylinder body 1 is fixedly connected with a support ring 9. The top of the support ring 9 is attached to the bottom of the overflow weir 7. A connecting mechanism 10 is arranged at the bottom of the overflow weir 7. An insertion assembly 11 is arranged at the top of the support ring 9.

[0020] Reference Figure 3 As shown in Figure 3 , the connecting mechanism 10 includes a knob 101, a threaded rod 102 and an L-shaped rod 103. The top of the knob 101 is in contact with the bottom of the overflow weir 7. The surface of the threaded rod 102 is threadedly connected to the inner wall of the knob 101. One end of the threaded rod 102 away from the sewage collection funnel 5 is fixedly connected to one end of the L-shaped rod 103 close to the sewage collection funnel 5. The other end of the L-shaped rod 103 penetrates through the overflow weir 7 and extends to the top of the overflow weir 7. The L-shaped rod 103 is movably connected to the overflow weir 7.

[0021] As a technical optimization scheme of the present utility model, by setting the connecting mechanism 10, pulling the L-shaped rod 103 can drive the threaded rod 102 and the knob 101 to move upward. The upward movement of the knob 101 can drive the overflow weir 7 to move upward, so as to facilitate the user to move the overflow weir 7 conveniently. By rotating the knob 101 to separate it from the threaded rod 102, it is convenient for the user to separate the L-shaped rod 103 and the overflow weir 7.

[0022] Reference Figure 3 As shown in Figure 3 , the plug-in assembly 11 includes an annular groove 111. The bottom of the overflow weir 7 is fixedly connected with a plug ring 112. The surface of the plug ring 112 is movably connected to the inner wall of the annular groove 111.

[0023] As a technical optimization scheme of the present utility model, by setting the plug-in assembly 11, the annular groove 111 can limit the plug ring 112 in the front, back, left and right directions. The front, back, left and right limit of the plug ring 112 can limit the overflow weir 7 in the front, back, left and right directions, thereby improving the stability of the overflow weir 7 on the top of the support ring 9.

[0024] Reference Figure 3 As shown in Figure 3 , one end of the L-shaped rod 103 away from the threaded rod 102 is fixedly connected with a plug-in member 12. The inner wall of the plug-in member 12 is movably connected to the surface of the top of the cylinder body 1. The top of the plug-in member 12 is fixedly connected with a pull rod 13.

[0025] As a technical optimization scheme of the present utility model, by setting the plug-in member 12 and the pull rod 13, the cylinder body 1 can limit the plug-in member 12 movably. The movable limit of the plug-in member 12 can play a role in supporting the L-shaped rod 103. By pulling the pull rod 13, the plug-in member 12 and the L-shaped rod 103 can be driven to move upward.

[0026] Reference Figure 1 As shown in Figure 1 , the bottom of the surface of the cylinder body 1 is fixedly connected with a fixing ring 14. The bottom of the fixing ring 14 is fixedly connected with a support frame 15.

[0027] As a technical optimization scheme of the present utility model, by setting the fixing ring 14 and the support frame 15, the fixing ring 14 can fix and limit the support frame 15. At the same time, the support frame 15 and the fixing ring 14 can play a role in stably supporting the cylinder body 1.

[0028] Reference Figure 2 On the surface of the connecting pipe 3, an umbrella-shaped plate 16 is fixedly connected. The umbrella-shaped plate 16 is located directly below the flow-stabilizing pipe 8. At the bottom of the inner wall surface of the cylinder body 1, a support plate 17 is fixedly connected. The inner wall of the support plate 17 is fixedly connected to the surface of the sewage-collecting funnel 5.

[0029] As a technical optimization scheme of the present utility model, by setting the umbrella-shaped plate 16 and the support plate 17, the umbrella-shaped plate 16 can play a role in evenly dispersing the sinking impurity particles in the sewage, thereby improving the precipitation efficiency of the impurity particles. The support plate 17 can play a role in fixing and limiting the sewage-collecting funnel 5.

[0030] The working principle and usage process of the present utility model: When in use, first connect the water inlet pipe 2 with the sewage discharge outlet inside the factory. At this time, the sewage will enter the inside of the flow-stabilizing pipe 8 through the water inlet pipe 2 and the connecting pipe 3. Most of the impurity particles in the sewage will evenly sink into the inside of the sewage-collecting funnel 5 through the umbrella-shaped plate 16. A small amount of suspended impurities will float in the overflow weir 7 along with the supernatant liquid. At this time, the supernatant liquid can flow out through the water outlet pipe 4, which is convenient for the user to recycle and use. And due to the blocking effect of the overflow weir 7, the suspended impurities can adhere to the inner wall surface of the overflow weir 7. After all the sewage is discharged, the user can discharge the impurities deposited in the sewage-collecting funnel 5 by turning the valve on the sewage discharge pipe 6. When the user needs to clean the inner wall of the overflow weir 7, first pull the pull rod 13 to drive the plug-in part 12, the L-shaped rod 103, the threaded rod 102 and the knob 101 to move upward in sequence. The upward movement of the knob 101 can drive the overflow weir 7 to move upward. After the overflow weir 7 is separated from the inside of the cylinder body 1, the user can turn the knob 101 to separate it from the threaded rod 102, which is convenient for the user to separate the L-shaped rod 103 from the overflow weir 7, thereby facilitating the user to clean the overflow weir 7.

[0031] In summary: For this factory sewage vertical flow sedimentation tank, by setting the support ring 9, the support ring 9 can support the overflow weir 7. The user can clean the inner wall of the overflow weir 7 by pulling the overflow weir 7 away from the support ring 9, which solves the problem that in the existing vertical flow sedimentation tank, after the large particle impurities in the sewage are filtered by sinking, there are still a small amount of suspended impurities floating in the overflow weir along with the refluxed supernatant liquid. And since the overflow weir is usually fixedly connected to the inner wall of the cylinder body, and the top of the overflow weir is multiple cones, it is more troublesome for the user to clean the suspended impurities inside it, and it is easy to cause scratches.
