In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of the ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the utility model.

[0034] The utility model provides a kind of sedimentation zone partition wall of sewage treatment sedimentation tank, the vertical partition 8 of the sedimentation zone partition wall is set to splicing type, when vertical partition 8 is deformed, the local vertical partition 8 can be disassembled and maintained, without being disassembled as a whole, to reduce the cost of maintenance.

[0035] In the embodiment, the structure of sewage sedimentation tank is as shown in Figure 1 As shown in Figure 1 Only part of sewage sedimentation tank is shown, mainly showing the part related to the utility model. The sedimentation tank of the utility model includes sewage sedimentation tank main body 1, water inlet pipe 2, water outlet pipe 3, sedimentation cavity 4, temporary storage cavity 5, water outlet 6, partition bottom plate 7, baffle 20. As shown in Figure 1 The inside of sewage sedimentation tank main body 1 is provided with sedimentation cavity 4 and temporary storage cavity 5, and sedimentation cavity 4 and temporary storage cavity 5 are separated by baffle 20, wherein one side of sedimentation cavity 4 is provided with water inlet pipe 2, one side of temporary storage cavity 5 is provided with water outlet pipe 3, side wall of baffle 20 is provided with water outlet 6, one side of water outlet 6 close to sedimentation cavity 4 is provided with partition bottom plate 7, one side of partition bottom plate 7 is provided with splicing type vertical partition 8. As shown in Figure 1As shown, the partition wall is spliced by a plurality of vertical partitions 8, while the partition wall in the prior art is a whole, thus in the long-term use process, the partition wall is prone to deformation due to the extrusion of water, thus affecting the filtering effect of the sewage, but the existing integral design needs to disassemble the whole partition wall during maintenance, which is high in cost, while the spliced partition wall only needs to replace the local damage during maintenance, thus saving the cost.

[0036] In the embodiment, as shown in Figures 2-6 The vertical partition 8 is uniformly arranged on the side wall of the partition bottom plate 7, one side of the vertical partition 8 is provided with a horizontal rod 9, and the two ends of the horizontal rod 9 are fixedly connected with the inner wall of the sediment cavity 4, wherein the horizontal rod 9 can not only be used as a connecting piece to install the vertical partition 8 on the side wall of the partition bottom plate 7, but also can be used as a reinforcing piece to provide a fulcrum for the vertical partition 8, so that the extrusion of water is dispersed at the connection between the partition bottom plate 7 and the vertical partition 8 and the connection between the vertical partition 8 and the horizontal rod 9, thereby increasing the service life of the vertical partition 8.

[0037] The side wall of the horizontal rod 9 is attached to the vertical partition 8, and the side wall of the horizontal rod 9 and the side wall of the partition bottom plate 7 are in the same vertical plane, such a design can ensure that the vertical partition 8 is vertically installed on the side wall of the partition bottom plate 7 and the horizontal rod 9, if the side wall of the horizontal rod 9 and the side wall of the partition bottom plate 7 are not in the same vertical plane, the installation position of the vertical partition 8 is inclined, when the vertical partition 8 is inclined to one side of the sediment cavity 4, the contact surface between the partition bottom plate 7 and the vertical partition 8 is inclined, which is much more difficult to install than the vertical setting, when the vertical partition 8 is inclined to one side of the baffle 20, the force of water changes, which increases the force of water on the vertical partition 8, thereby reducing the service life of the vertical partition 8, therefore, compared with the inclined setting, the vertical design can not only ensure convenient installation, but also increase the service life of the vertical partition 8 to a certain extent.

[0038] In the embodiment, as shown in Figure 2 and Figure 5 Two adjacent vertical partitions 8 are connected by a vertical rod 10, and the vertical rod 10 is fixedly installed on one side of the horizontal rod 9, wherein the bottom end of the vertical rod 10 is flush with the bottom end of the partition bottom plate 7. Such a design can block the gap between the two adjacent vertical partitions 8, so as to prevent the sewage from entering the temporary storage cavity 5, thereby avoiding the substandard water quality, in addition, the vertical rod 10 can play a guiding role during the installation of the vertical partition 8, and the installation position can be quickly found.

[0039] Further, in the embodiment, the vertical partition plate 8 is provided with a notch 18 at both ends of the side close to the horizontal rod 9. The notch 18 is parallel to one side of the partition plate bottom plate 7 and is attached to the side wall of the vertical rod 10. The vertical rod 10 can block the gap between the vertical partition plates 8, so as to avoid the sewage flowing out of the gap between the vertical partition plates 8 and affecting the water quality. The gap between the two ends of the vertical rod 10 and the side of the notch 18 perpendicular to the partition plate bottom plate 7 has a gap, and the distance of the gap is less than one fourth of the length of the side of the notch 18 parallel to the partition plate bottom plate 7. In this way, the design can avoid the error of the vertical partition plate 8 during production, which causes the vertical partition plate 8 to be unable to be embedded between the vertical rods 10 or the side wall surface of the vertical partition plate 8 is not smooth enough and is easy to be stuck, thereby causing the problem of difficult installation.

[0040] The side wall of the vertical rod 10 is provided with a guide block 16. The cross section of the guide block 16 is trapezoidal, which can play a guiding role during installation, so that the vertical partition plate 8 can be embedded between the two vertical rods 10 along the guide block 16.

[0041] In the embodiment, one side of the vertical partition plate 8 is provided with two upper and lower installation grooves 11. The installation grooves 11 are provided with a limiting block 17 at the groove opening. The inside of one installation groove 11 is provided with a first end head 12. One end of the first end head 12 is fixedly installed with a threaded rod 13. The threaded rod 13 penetrates through the horizontal rod 9 and extends to one side of the horizontal rod 9. The outer wall of the threaded rod 13 is threadedly connected with a nut 14. The nut 14 is arranged on one side of the horizontal rod 9. The inside of the other installation groove 11 is provided with a second end head 15. One end of the second end head 15 is fixedly installed on one side of the partition plate bottom plate 7. The lower part of the limiting block 17 is inclined, which facilitates the smooth entry of the first end head 12 and the second end head 15 between the limiting blocks 17. In addition, the limiting block 17 has two parts. The distance between the two parts of one limiting block 17 is less than the diameter of the first end head 12. The distance between the two parts of the other limiting block 17 is less than the diameter of the second end head 15. In this way, when the first end head 12 and the second end head 15 are arranged between the limiting blocks 17, the limiting blocks 17 can block the first end head 12, so that the first end head 12 and the second end head 15 cannot be separated from the limiting blocks 17. When the vertical partition plate 8 is maintained and installed, only the first end head 12 and the second end head 15 need to be arranged in the installation groove 11. Then, the vertical partition plate 8 is pressed downward until the first end head 12 is embedded between the limiting blocks 17. Finally, the nut 14 is rotated to install the vertical partition plate 8 and fix it on the side wall of the partition plate bottom plate 7 and the horizontal rod 9. Compared with directly connecting with screws, the design can reduce the operation of punching holes on the horizontal rod 9 and the vertical partition plate 8, and make the installation more convenient.

[0042] Further, in the embodiment, the inner wall top end of the mounting groove 11 provided with the second end head 15 is lower than the top end of the partition bottom plate 7, so that after installation, sewage cannot flow out from the gap between the partition bottom plate 7 and the mounting groove 11, and the water quality in the partition bottom plate 7 is not substandard.

[0043] The above are only preferred embodiments of the present application, and do not limit the patent range of the present application, and any equivalent structural transformation made under the utility model concept of the present application, or direct / indirect application in other related technical fields is included in the patent protection range of the present application.
