DETAILED DESCRIPTION

[0020] The utility model is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In the description of the utility model, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the utility model. In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a connection between the two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood by specific circumstances.

[0021] like Figure 1 , Figure 2 As shown, the utility model provides a water flow deceleration and liquid medicine mixing device, comprising a cylinder A1, the top surface of the cylinder A1 is provided with a first water inlet pipe A3 and two first medicine adding pipes A4, and a plurality of first water outlets are evenly distributed around the axis of the cylinder A1 at a position close to the lower end of the cylinder A1 on the side wall of the cylinder A1;

[0022] A guide baffle is provided in the middle of the cylinder A1, and a water hole is provided in the center of the guide baffle. A deceleration and mixing base A5 is provided at the bottom of the cylinder A1. A mixing groove A5-1 facing the water hole is provided at the center of the top surface of the deceleration and mixing base A5. A second overflow annular groove A5-3 is provided at the outer edge of the bottom of the deceleration and mixing base A5, and the outer wall of the second overflow annular groove A5-3 coincides with the inner wall of the cylinder A1.

[0023] In the above structure, sewage enters the cylinder A1 from the first water inlet pipe A3, and two chemicals (polyaluminium chloride (PAC) and polyacrylamide (PAM)) enter the cylinder A1 from the two first dosing pipes A4 respectively. The three liquids collide on the guide plate and then slow down and mix, and then flow into the mixing tank A5-1 from the water outlet. The liquid hits the inner wall of the mixing tank A5-1 and slows down and mixes again. After the mixing tank A5-1 is full, the liquid flows from the edge of the mixing tank A5-1 into the second overflow annular groove A5-3, and is slowed down and mixed for the third time by hitting the inner wall of the second overflow annular groove A5-3, and then flows out from the first water outlet. The sewage and the chemical liquid are slowed down and mixed many times in the cylinder A1, and the effect of slowing down the liquid and mixing the chemical liquid is achieved, and then it flows out of the cylinder A1 and enters the clarifier.

[0024] The first water outlet is connected with a water outlet guide pipe A2, and the axis of the water outlet guide pipe A2 is perpendicular to the axis of the cylinder A1.

[0025] The guide baffle is a funnel-shaped guide baffle A6, which can guide the flow direction.

[0026] The deceleration and mixing base A5 is a frustum structure, and the side wall of the frustum structure plays the role of deceleration and drainage.

[0027] A plurality of first overflow annular grooves A5-2 are arranged from top to bottom on the side wall of the deceleration and mixing base A5. The first overflow annular grooves A5-2 can increase the number of collisions of the liquid on the side wall of the deceleration and mixing base A5, thereby further playing the role of deceleration and mixing.

[0028] The present application also relates to a high-efficiency clarifier having the above water flow deceleration and liquid medicine mixing device, such as Figures 2 to 4 As shown, the water flow deceleration and liquid medicine mixing device A is fixed in the coagulation area B15 inside the high-efficiency clarifier through the connecting bracket B4. The high-efficiency clarifier is provided with a second water inlet pipe B3 and two second dosing pipes B13. The first water inlet pipe A3 is connected to the second water inlet pipe B3, and the first dosing pipe A4 is connected to the second dosing pipe B13.

[0029] The sludge concentration zone B9, flocculation zone B6, inclined tube sedimentation zone B5 and clarification zone B11 are arranged from bottom to top in the high-efficiency clarifier. The coagulation zone B15 is arranged along the axial direction of the high-efficiency clarifier. The coagulation zone B15 spans the clarification zone B11, the inclined tube sedimentation zone B5 and the flocculation zone B6. The inclined tube sedimentation zone B5 is composed of a plurality of hexahedral through-hole inclined tubes. An outlet weir plate B2 and a water collecting tank B1 are arranged above the clarification zone B11. The water collecting tank B1 is connected to the outlet pipe B12.

[0030] An umbrella-shaped guide plate B8 is provided below the coagulation zone B15 via an umbrella-shaped guide plate bracket B7.

[0031] The workflow of an efficient clarifier:

[0032] 1. Sewage enters the water flow deceleration and liquid medicine mixer A from the second water inlet pipe B3, and the liquid medicine also enters the water flow deceleration and liquid medicine mixer A through the first dosing pipe A4. After the water flow and liquid medicine are decelerated and mixed by the water flow deceleration and liquid medicine mixer A, they are discharged into the coagulation area B15 through the outlet diversion pipe A2.

[0033] 2. When the water flows into the coagulation area B15 and hits its inner wall, the water flow will be further decelerated, and the sewage and the liquid medicine will be fully coagulated.

[0034] 3. The water in the coagulation zone B15 enters the flocculation zone B6 through the umbrella-shaped guide plate B8 below it. The suspended particles in the water in the flocculation zone B6 react with the coagulant to form tiny floccules that move with the water flow. During the movement, the small floccules collide with each other to form large floccules. The large floccules will settle down into the sludge concentration zone B9 at the bottom of the clarifier by their own weight. The small floccules will follow the water flow into the inclined tube sedimentation zone B5 above.

[0035] 4. The inclined tube sedimentation area B5 is composed of multiple hexahedral oblique tubes. The inclined tubes pave the entire inclined tube sedimentation area B5. When small flocs containing solid matter enter the inclined tube sedimentation area B5, the flocs will be adsorbed on the wall of the inclined tube. When the flocs adsorbed on the wall of the inclined tube are enough to form large flocs, the flocs will automatically fall off due to their own weight and fall into the sludge concentration area B9 below.

[0036] 5. The water passing through the inclined tube sedimentation area B5 is the dischargeable clean water. When there is enough clean water in the clarification area B11, it will overflow from the outlet weir plate B2 into the water collecting tank B1. The water in the water collecting tank B1 is discharged from the clarifier through the outlet pipe B12.

[0037] 6. The sludge in the sludge concentration area B9 needs to be discharged regularly to prevent excessive sludge from clogging the pipeline and affecting the effluent quality.

[0038] The above is a detailed description of the embodiments of the utility model, but the contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
