Embodiment Construction

[0020] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments.

[0021] Such as figure 1 As shown, a novel rotating tangential flow high-efficiency vertical flow sedimentation tank provided by this patent has a cylindrical tank body 1 at the top and a conical sludge bucket 2 at the bottom. The tank body 1 is provided with a water inlet pipe 4 and a central guide. Flow tube 5, reflection cone 6, outlet tank and outlet pipe, and sludge treatment system.

[0022] The mud-water mixture enters the central guide tube 5 from the water inlet pipe 4, and the water outlet from the bottom of the central guide tube 5 contacts the reflective cone 6 and disperses evenly around. Mud bucket 2, so as to realize the separation of mud and water.

[0023] The sludge treatment system includes a sludge discharge pipe 82, a sludge return pipe 83...

Abstract

The invention discloses a novel rotary tangential flow efficient vertical flow sedimentation tank which comprises a cylindrical tank body positioned at the upper part and a conical sludge hopper positioned at the lower part, wherein a water inlet pipe, a central guide cylinder, a reflecting cone and a water collecting tank are arranged in the tank body; the efficient vertical flow sedimentation tank further comprises a sludge treatment system; the sludge treatment system comprises a sludge discharge pipe, a sludge return pipe, a flushing hose and a sludge pump; the sludge pump is arranged at an outlet of the conical sludge hopper; the sludge pump is used for introducing a sludge-water mixture sucked from the conical sludge hopper into the sludge discharge pipe, the sludge return pipe and/or the flushing hose; the sludge hopper is provided with a flushing pipe orifice for connecting the flushing hose; a flow guide groove is formed in the inner wall of the sludge hopper, the flow guide groove spirally ascends to the joint of the tank body and the sludge hopper from the bottom of the sludge hopper, the flushing pipe orifice is formed in the position of the flow guide groove, and the outflow direction of the flushing pipe orifice is the tangential direction of the flow guide groove.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to a novel rotating tangential flow high-efficiency vertical flow sedimentation tank. Background technique [0002] At present, the sedimentation tank is a device used in the field of water treatment to remove impurities in water and realize the separation of mud and water. Among them, the vertical flow sedimentation tank has the advantages of less land occupation, simple installation, and convenient management. It is widely used in sewage treatment plants and some small and pilot experiments. The vertical flow sedimentation tank is equipped with a sludge return pump as a sludge pump. Realize sludge discharge and sludge return. However, some small vertical flow sedimentation tanks only rely on gravity to disperse and deposit the sedimented sludge in the conical sludge hopper, and it is often difficult for the sludge to slide down to the bottom of the sludge hopper by stat...
