Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically, to a heavy-duty inclined plate sedimentation tank for sewage treatment. Background Technique

[0002] A sedimentation tank is a water purification device that uses the gravity sedimentation effect to separate suspended solids or flocs in water. The sedimentation tank is generally a structure for separating muddy water before or after biochemical treatment, and is mostly used to separate sludge with finer particles. The tank shape of the traditional inclined plate sedimentation tank is a cubic shape, and the inclined plate uses a PP honeycomb inclined plate filler with a thickness of 0.6 mm and a length of 1 m. This inclined plate filler is welded layer by layer into blocks of a certain size, and then placed into the sedimentation tank one by one. After that, sewage is introduced to precipitate the internal impurities.

[0003] In the actual use process of the existing inclined plate sedimentation tank for sewage treatment, due to the relatively thin thickness of the inclined plate itself and the low mechanical strength of the filler, there is a risk of being crushed by sludge when treating sewage with a high content and large specific gravity of suspended solids. Moreover, the length of the inclined plate is only 1 m, and the depth of the sedimentation tank is not fully utilized. Therefore, there is an urgent need to improve the technology of the structure of the inclined plate sedimentation tank for sewage treatment to improve this device. Content of the Utility Model

[0006] 2. Technical Solutions

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A heavy-duty inclined plate sedimentation tank for sewage treatment includes a sedimentation tank. An installation frame is fixedly connected inside the sedimentation tank. An inclined plate module is detachably installed above the installation frame. The inclined plate module is provided with two columns in total. An inlet is opened at the left end of the sedimentation tank, and an outlet is opened at the right end of the sedimentation tank. A water distribution plate is fixedly connected to the inner bottom wall of the sedimentation tank.

[0009] Furthermore, both the installation frame and the inclined plate module are inclined in the sedimentation tank, and the inclination angles between the installation frame, the inclined plate module and the inner bottom wall of the sedimentation tank are all 60°.

[0010] Further, the length of the inclined plate module is 1.5 m to 2 m, and the thickness of the inclined plate module is 6 mm.

[0011] Further, a rectangular steel profile frame is provided outside the inclined plate module, and a plurality of horizontally and vertically arranged steel bars are welded at the inner wall of the steel profile frame.

[0014] 3. Beneficial effects

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

By making the thickness of the inclined plate module installed in the sedimentation tank reach 6 mm, a plurality of steel bars pass through the inside of the inclined plate module at a fixed interval and are firmly connected. Several inclined plates are grouped together, and the outside is reinforced with steel profiles to form a module, enhancing the hardness of the inclined plate module, so that the resistance of the inclined plate module in the sedimentation tank to sludge pressure is significantly enhanced, facilitating use.

[0017] (2) In the present utility model, by arranging an inverted V-shaped water distribution plate between two rows of inclined plate modules, after the sewage is put into the sedimentation tank through the water inlet, the water flow is divided by the water distribution plate, so that the water flow distribution inside the sedimentation tank is uniform. The sewage can pass through the inclined plate module, settle by gravity, and the inclined plate module blocks the suspended matter in the sewage, and then flows out through the water outlet, so that there is no turbulent flow and no dead zone in the sedimentation tank, and the hydraulic load is higher.

By making the thickness of the inclined plate module 3 installed in the sedimentation tank 1 reach 6mm, multiple steel bars 302 pass through the fixed spacing inside the inclined plate module 3 and are firmly connected. Several inclined plates are grouped together, and the outside is reinforced with steel profiles to form a module, enhancing the hardness of the inclined plate module 3, significantly enhancing the anti-sludge pressure of the inclined plate module 3 in the sedimentation tank 1, and facilitating use.
