Mechanical stirring and clarifying tank with novel oblique pipe support frames

Abstract

The invention provides a mechanical stirring and clarifying tank with novel oblique pipe support frames. The mechanical stirring and clarifying tank comprises a clarifying tank, oblique pipes fully arranged in the clarifying tank and oblique pipe support frames used for supporting the oblique pipes, wherein each oblique pipe support frame comprises a support frame, a main cross beam, a secondary cross beam, an edge sealing beam and grid cover plates; the support frames are triangular frames used for supporting the oblique pipes in the vertical direction; each support frame comprises a horizontal beam, a diagonal bracing, a vertical web member and a diagonal web member; a plurality of support frames are uniformly distributed at the periphery of the clarifying tank and are arranged along a radial direction; the main cross beams, the secondary cross beams and the edge sealing beams are connected between adjacent support frames along the periphery of the clarifying tank at the bottoms of the oblique pipes; large cover plates with uniformly-distributed grids are paved among two adjacent horizontal beams, the main cross beams and the wall of the clarifying tank; small cover plates with uniformly-distributed grids are paved among two adjacent horizontal beams, the main cross beams and the edge sealing beams; the edge of each cover plate is enclosed by a cover plate frame. The supportframes can meet the restricted condition that the support frames are only fixed on single side of the stirring and clarifying tank and also can simultaneously stably support the oblique pipes and ensure smooth flowing of the water flow and the precipitates; the materials are saved, and the safety is ensured.

Description

technical field [0001] The invention relates to an inclined tube support in water treatment equipment, in particular to a mechanically stirred clarifier with a novel inclined tube support. Background technique [0002] The mechanical stirring clarifier is to install inclined pipes in the clarifier pool to further improve the sedimentation effect and improve the effluent water quality. The inclined pipe needs to cover the entire clarification area, and the rising water flows through the inclined pipe for sedimentation, and the sediment gradually accumulates in the inclined pipe to a certain amount and then slides down. The inclined pipe needs to bear the impact of water flow and the gravity of sediment during the water purification process, so the inclined pipe needs to be supported. [0003] Such as figure 1 As shown, the traditional way of supporting inclined pipes in the mechanically stirred clarifier pool is to set up cast-in-situ concrete diagonal braces and prefabrica...

Problems solved by technology

This will increase the workload of civil construction, waste the volume of the tank, reduce the residence time of the clarifier and reduce the treatment efficiency

[0006] 2) Due to the poor stability of the support structure, it is only used in pools with a diameter of less than 22m. In order to ensure that the weight of the inclined pipe needs to be supported, a large number of supports is required, resulting in increased investment and affecting the flow state in the pool

[0008] 1) The traditional inclined tube support method supported at both ends cannot be used in the new mechanically stirred clarifier

[0009] 2) The existing new mechanically stirred clarifier inclined tube bracket based on the traditional support method has poor structural stability, and is only used in pools with a diameter of less than 22m. In order to ensure that the weight of the inclined tube can be supported, a large number of brackets are required, resulting in Investment increases and affects the flow state in the pool

[0010] 3) Due to the vertical support of the inclined pipe support of the new mechanically stirred clarifier tank, the operating diameter of the mud scraper at the bottom is affected. In order to avoid the problem of mud accumulation, it is necessary to pour the inner side of the tank body into a slope

This will increase the workload of civil construction, waste the volume of the tank, reduce the residence time of the clarifier and reduce the treatment efficiency
