Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, and particularly relates to an overhaul device for a sewage treatment system. Background Technique

[0002] With the gradual strengthening of people's awareness of environmental protection, sewage treatment has gradually become an essential process in industrial production. Whether it is an enterprise with a large amount of production wastewater or an enterprise with a small amount of production wastewater, if reliable and effective sewage treatment is not carried out, it will cause extremely serious pollution to the environment. In the prior art, a very comprehensive sewage treatment system has been formed, including three major parts: a pretreatment system, a biochemical treatment system, and a mud-water filtration system. Among them, the biochemical treatment system is mainly composed of treatment systems such as anaerobic, anoxic, and aerobic, and is usually made into an anaerobic tank, an anoxic tank, an aerobic tank, and a sedimentation tank, etc. Among them, in the aerobic tank, since a large amount of oxygen needs to be introduced, in the existing large aerobic tanks, generally an intake steel pipe spans the tank body, and a number of intake pipes are connected to the intake steel pipe. The bottom of the intake pipe is connected to an intake soft rubber pipe, and a number of intake holes are provided on the side wall of the intake soft rubber pipe to supply air to the aerobic tank. However, since the intake holes are prone to blockage, it is necessary for the staff to disassemble and replace the intake soft rubber pipe. Since the aerobic tank is relatively large, the existing disassembly and replacement method is generally to install a walking platform near the intake steel pipe, and people lie on the walking platform to disassemble the intake soft rubber pipe; but since the position of the intake soft rubber pipe is relatively low, lying on the stomach to disassemble is relatively dangerous, and at the same time, after working for a long time, the staff is prone to lack of oxygen and fall into the aerobic tank. Content of the Utility Model

[0003] The purpose of the utility model is to design an overhaul device for a sewage treatment system to solve the problems raised in the background technique. To achieve the above purpose, the utility model provides the following technical solutions: including not less than two intake steel pipes installed on the aerobic tank and a walking platform, and further including two moving frames, moving rods adjustably installed at both ends of the moving frames, and a support frame lapped on the two moving rods. The bottom of the moving frame is provided with two rows of first rollers arranged obliquely and tangent to the surface of the intake steel pipe. The symmetry plane of the two rows of first rollers is a vertical plane and the symmetry plane coincides with the axis of the intake steel pipe. The support plate of the support frame is located below the walking platform.

[0004] Further, the support frame includes four lapping rods lapped on the moving rods and the support plate fixedly connected to the bottom of the lapping rods.

[0005] Further, a protective rod is provided between the lapping rods.

[0006] Further, a cross rod is fixedly connected to the bottom of the support plate, and the cross rod is fixedly connected to the lapping rod.

[0007] Furthermore, the moving frame includes a moving column adjustably connected to the moving rod and a connecting column connecting the two moving columns. A bevel platform is fixedly connected to the bottom of the moving column, and the first roller is fixedly connected to the bevel platform.

[0008] Furthermore, a plurality of second rollers tangent to the intake steel pipe are fixedly connected to the bottom of the connecting column.

[0009] Furthermore, an adjustment notch is provided on the moving rod. The moving column is slidably connected to the moving rod. The top of the moving column is threadedly connected to an adjustment bolt. The end of the adjustment bolt passes through the adjustment notch, and the end of the adjustment bolt passing through the adjustment notch is threadedly connected to a clamping block, and the clamping block is located inside the moving rod.

[0010] Furthermore, the clamping block is a square block, and the clamping block is slidably connected to the inside of the moving rod.

[0011] Furthermore, a stud threadedly connected to the adjustment bolt is provided on the clamping block.

[0012] Furthermore, the adjustment bolt is a wing bolt.

[0021] Embodiment: Please refer to Figures 1 - 3 , a maintenance device for a sewage treatment system, including no less than two intake steel pipes 3 and a walking platform 2 installed on the aerobic tank 1, further including two moving frames 4, moving rods 5 adjustably installed at both ends of the moving frames 4, and a support frame 6 lapped on the two moving rods 5. The bottom of the moving frame 4 is provided with two rows of first rollers 14 arranged obliquely and tangent to the surface of the intake steel pipe 3. The symmetry plane of the two rows of first rollers 14 is a vertical plane and coincides with the axis of the intake steel pipe 3. The support plate 15 of the support frame 6 is located below the walking platform 2. When it is necessary to disassemble and replace the intake soft rubber pipe, one operator squats on the support frame 6, and other operators stand on the walking platform 2 to push the moving rod 5 (it can also be pushed by the person squatting on the support frame 6). This method enables the operator to be closer to the intake soft rubber pipe, and the operator does not need to lie prone to disassemble and replace the intake soft rubber pipe, preventing the situation that the operator falls into the aerobic tank 1 due to lack of oxygen during prone operation.

A bevel is fixedly connected to the bottom of the moving column 16, and a first roller 14 is fixedly connected to the bevel. And a plurality of second rollers 10 tangent to the intake steel pipe 3 are fixedly connected to the bottom of the connecting column 11, thereby improving the support strength of the moving column 16 and the service life of the first roller 14; an adjustment notch 12 is provided on the moving rod 5, and the moving column 16 is slidably connected to the moving rod 5. The top of the moving column 16 is threadedly connected with an adjustment bolt 13, and the end of the adjustment bolt 13 penetrates through the adjustment notch 12. The end of the adjustment bolt 13 penetrating through the adjustment notch 12 is threadedly connected with a clamping block 7, and the clamping block 7 is located inside the moving rod 5, so as to adapt to two intake steel pipes 3 with different spacings and improve the flexibility of the device; and the clamping block 7 is a square block, and the clamping block 7 is slidably connected to the inside of the moving rod 5. The adjustment bolt 13 is a butterfly bolt, and a stud 17 threadedly connected with the adjustment bolt 13 is provided on the clamping block 7; while being convenient for adjustment, the connection strength of the threaded connection is improved.

[0023] Working principle

[0024] When the intake soft rubber tube needs to be disassembled and replaced, first adjust the distance between the two moving frames 4 according to the distance between the two intake steel pipes 3, and then engage the first roller 14 and the second roller 10 in the adjusted moving frame 4 in the intake steel pipe 3; then overlap the overlapping rod 9 on the moving rod 5, and then the operator squats on the support frame 6 and pushes the moving rod 5 while disassembling the intake soft rubber tube, so as to realize the disassembly and replacement of the intake soft rubber tube in the intake steel pipe 3; during the use of this utility model, the operator does not need to lie on his stomach to disassemble and replace the intake soft rubber tube, preventing the situation that the operator falls into the aerobic tank 1 due to lack of oxygen during lying-on-stomach operation.
