At present, a sedimentation tank of a middle and small sewage treatment plant generally adopts a central transmission mud scraping mode, adopts a radial sedimentation tank with central water inlet and peripheral water outlet, and after the water inlet passes through a water inlet pipe to a steady flow cylinder, the water slowly flows along the radial direction towards the periphery of the tank, suspended matters settle in the flowing process and enter a sludge hopper along the gradient of the bottom of the tank, and clarified water overflows from the periphery of the tank to a water outlet channel. The water inlet pipe entering the steady flow cylinder matched with the central transmission mud scraper generally has two modes: firstly, under the condition of elevation permission, a water inlet pipe directly enters water from the top of the center of the steady flow cylinder, an elbow is arranged downwards on the water inlet pipe for water distribution, and the uniform water inlet in the center cannot be realized due to the blocking of a transmission shaft of a center transmission mud scraper; secondly, for the middle-size and small-size sewage treatment plant because of the convenience of high limit and construction, the inlet tube is direct to follow stationary flow section of thick bamboo side water intaking, inserts the stationary flow section of thick bamboo with the inlet tube back, upwards sets up the elbow, and water flows upwards and then downwards passes through stationary flow section of thick bamboo and distributes water to the sedimentation tank after flowing upwards, however this kind of mode because the in-process of water downflow, the inlet tube in the stationary flow section of thick bamboo can lead to water downflow uneven to lead to stationary flow section of thick bamboo play water inhomogeneous, influence the sedimentation effect, the sedimentation tank "runs out" phenomenon can appear in long-time operation.

In particular, no impact of water inflow exists at the position far away from the water inlet, mud is accumulated easily for a long time, the distribution uniformity of water inflow in the annular channel 6 can be influenced by accumulation to a certain height, in order to avoid the occurrence of the phenomenon, three mud discharging holes are uniformly distributed on one side of the sealing plate far away from the water inlet pipe, the aperture of each mud discharging hole is 0.02cm, and thus the mud is discharged through the mud discharging holes, and the mud accumulated in the annular channel far away from the water inlet pipe is avoided.
In particular, in order to facilitate processing, the steady flow cylinder, the water distribution cylinder and the sealing plate are formed by welding stainless steel plates or carbon steel corrosion-resistant steel plates.
Compared with the prior art, the steady flow cylinder device provided by the utility model has the following beneficial effects:
1. and (3) water distribution is uniform: the water inlet pipe is communicated with the steady flow cylinder, water enters an annular channel between the steady flow cylinder and the water distribution cylinder through the water inlet pipe, and turns upwards through a triangular weir at the top of the internal water distribution cylinder to realize uniform water distribution;
2. the size is adjustable: the steady flow cylinder, the water distribution cylinder and the like can be adjusted and determined according to the actual project scale, and the applicability is high;
3. the cost is low: the structure is simple, the stainless steel plate or the carbon steel corrosion-resistant steel plate is made of the materials, the processing and the installation are convenient, and the production cost is reduced.
4. The feasibility of practical application is high: at present, radial flow sedimentation tanks with central water inlet and peripheral water outlet are mostly adopted as sedimentation tanks of small and medium sewage treatment plants, and central transmission mud scrapers are mostly adopted as mud scrapers.
