Description

Technical Field

[0001] This utility model relates to water treatment technology, specifically a high-efficiency coagulation mixer. Background Technology

[0002] Coagulation refers to the process of aggregating colloidal particles and tiny suspended solids in water by adding chemical agents, and it is a unit operation in water treatment. When coagulants are added to wastewater, they need to be stirred and dispersed by a mixer to ensure that the coagulants come into full contact with the impurities in the wastewater.

[0003] However, most mixers on the market currently have the following defects: the mixer generally only has a mixing zone. After mixing by the mixing blades, it needs to be left to stand to allow the air bubbles to be expelled and the coagulated impurities to settle by gravity. Only after the water and impurities are separated can it be discharged or further treated. Therefore, it cannot continuously carry out coagulation work and needs to be shut down periodically, which greatly affects the efficiency of water treatment. Utility Model Content

[0004] To address the shortcomings of the existing technology, this invention provides a high-efficiency coagulation mixer with an added settling chamber for allowing the mixed liquid to settle, thus facilitating the upward release of air bubbles and the sequential settling of large and small particles of impurities after coagulation. This eliminates the need for timed shutdowns and allows for continuous coagulation and mixing, significantly improving water treatment efficiency.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: a high-efficiency coagulation mixer, comprising a mixing chamber and a settling chamber, wherein the settling chamber is located on one side of the mixing chamber, the top of the settling chamber is connected to the top of the mixing chamber, the top of the settling chamber is connected to an inlet pipe and a dosing pipe, the bottom of the settling chamber is connected to an exhaust pipe, the settling chamber is provided with a mixing unit, the bottom of the mixing chamber is provided with an aeration plate, the bottom of the settling chamber is connected to a waste discharge pipe, and the top of the settling chamber is connected to a drain pipe.

[0007] Preferably, the overflow chamber is provided with a diversion plate, the diversion plate is inclined, and the end of the diversion plate facing the mixing chamber is higher than the end away from the mixing chamber.

[0008] Preferably, a drainage pipe is connected below the overflow chamber, and the drainage pipe extends into the bottom of the settling chamber.

[0009] Preferably, the stirring unit includes a motor and a stirring shaft. The motor is fixed above the stirring chamber and drives the stirring shaft to rotate. The stirring shaft extends into the stirring chamber. The stirring shaft has sleeves evenly distributed from top to bottom, and stirring blades are provided on the outer periphery of the sleeves.

[0010] Preferably, the stirring blades are provided with several through holes.

[0011] Preferably, the aeration plate has a communicating cavity, and aeration holes are evenly distributed on the top of the aeration plate, and the aeration holes communicate with the communicating cavity.

[0012] Preferably, the bottom of the aeration plate is provided with a plurality of downward spray holes, which are connected to the connecting cavity.

[0023] Example 1:

[0024] like Figure 1 As shown, a high-efficiency coagulation mixer includes a mixing chamber 1 and a settling chamber 2. The settling chamber 2 is located on one side of the mixing chamber 1. The top of the settling chamber 2 is connected to the top of the mixing chamber 1. The top of the settling chamber 2 is connected to an inlet pipe 3 and a dosing pipe 4. The bottom of the settling chamber 2 is connected to an exhaust pipe 5. The settling chamber 2 is equipped with a mixing unit. The bottom of the mixing chamber 1 is equipped with an aeration plate 8. The bottom of the settling chamber 2 is connected to a waste discharge pipe 15. The top of the settling chamber 2 is connected to a drain pipe 14.

[0025] The inlet pipe 3 is used to introduce the wastewater to be treated; the dosing pipe 4 is used to add coagulant at regular intervals and in measured quantities; the drain pipe 5 is used to drain the residual liquid in the mixing chamber 1 and discharge the wastewater from cleaning and maintenance when the coagulation and mixing work is completed or during regular maintenance; the drain pipe 14 is used to discharge the treated water from the top of the settling chamber 2; and the waste discharge pipe 15 is used to discharge the settled impurities and residual wastewater in the settling chamber 2.

[0026] The high-efficiency coagulation mixer in this embodiment is equipped with a settling chamber 2 to allow the mixed liquid to settle, so that the air bubbles rise and are discharged, and the large particles and small particles after coagulation settle in sequence. It can continuously carry out coagulation and mixing without frequent shutdowns, which greatly improves the efficiency of water treatment.

[0027] The settling chamber 2 is equipped with an overflow chamber 11 at its top. The top of the overflow chamber 11 is connected to the top of the stirring chamber 1, and the bottom of the overflow chamber 11 is connected to the settling chamber 2. A guide plate 12 is installed inside the overflow chamber 11. The guide plate 12 is inclined, with one end of the guide plate 12 facing the stirring chamber 1 higher than the end away from the stirring chamber 1. A guide pipe 13 is connected below the overflow chamber 11 and extends into the bottom of the settling chamber 2. The guide plate 12 is used to smoothly guide the liquid flow into the overflow chamber 11, and the guide pipe 13 is used to guide the liquid in the overflow chamber 11 into the bottom of the settling chamber 2. This arrangement, in conjunction with the overflow chamber 11, prevents the overflow liquid in the stirring chamber 1 from falling rapidly and affecting the normal settling operation of the settling chamber 2.

[0028] The stirring unit includes a motor 6 and a stirring shaft. The motor 6 is fixed above the stirring chamber 1 and drives the stirring shaft to rotate. The stirring shaft extends into the stirring chamber 1, and sleeves are evenly distributed from top to bottom on the stirring shaft. Stirring blades 7 are provided on the outer periphery of the sleeves. The stirring blades 7 are provided with several through holes. The through holes allow convection of liquid on both sides of the stirring blades 7, thereby improving the stirring and dispersion effect.

[0029] The aeration plate 8 has a communicating cavity inside, and aeration holes 9 are evenly distributed on the top of the aeration plate 8, which communicate with the communicating cavity; the bottom of the aeration plate 8 has several downward spray holes 10, which communicate with the communicating cavity. The downward spray holes 10 allow bubbles to spray downwards, causing impurities deposited at the bottom of the mixing chamber 1 to rise upwards.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
