Description

Technical Field

[0001] The utility model relates to the technical field of dosing devices, in particular to a coagulant cyclone dosing device. Background Art

[0002] Coagulants used for sewage treatment are divided into two types: solid and liquid, depending on the source and physical form of the agent. Solid coagulants need to be added to the inside of the coagulation reaction tank using a dosing device for use. For example, the patent with publication number CN214327226U discloses a solid coagulant cyclone dosing device, including a box body, a water inlet pipe is fixedly connected to one side of the outer wall of the box body, a conical cylinder is fixedly connected to the bottom of the box body, a top cover is detachably connected to the top of the box body, a motor is installed on the top of the top cover, and the power output end of the motor is connected to a transmission shaft extending to the inside of the conical cylinder, and the outer wall of the transmission shaft is fixedly connected There are stirring blades, and one end of the guide plate of the stirring blade is tilted downward. The sewage entering the box body flows down along the guide plate and is mixed with the solid reagent in the process of flowing down. Under the action of the guide plate, the sewage and the reagent can be mixed in a vortex. At the same time, the restriction of the guide plate is used to prevent the sewage from flowing directly down along the inner wall of the box, thereby ensuring the quality of the vortex mixing. The high-speed rotating stirring blades are used to fully stir the sewage to be discharged. However, the size of the box itself will limit the retention time of the sewage. Even if the sewage is highly stirred, the short existence time will affect the mixing of the sewage and the coagulant, and the use of a motor to drive the stirring will also cause a waste of resources.

[0003] To this end, the utility model provides a coagulant cyclone dosing device. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 5 The utility model provides a technical solution: a coagulant cyclone dosing device, comprising a box body 1, a rotating shaft 3 is rotatably provided in the box body 1, a water inlet pipe 2 is installed on one side of the box body 1, a plurality of baffles 9 and a plurality of stirring rods 10 are installed on the circumference of the rotating shaft 3, a dosing box 4 is installed on the upper side of the box body 1, a feeding structure is installed in the dosing box 4, and the feeding structure corresponds to the rotating shaft 3, a plurality of extended mixing drums 13 are installed on the lower side of the box body 1, and a first cyclone 14 and a second cyclone 15 are installed in the extended mixing drum 13.

[0023] In this embodiment, the box body 1 is fixedly connected to the water inlet pipe 2, the water inlet pipe 2 is communicated with the box body 1, the water inlet pipe 2 is tangent to the inner wall of the box body 1, the baffle 9 and the stirring rod 10 are both fixedly connected to the rotating shaft 3, the baffle 9 corresponds to the water inlet pipe 2, and the stirring rod 10 is located on the lower side of the water inlet pipe 2.

[0024] Specifically, when sewage is introduced, the sewage pushes the baffle 9, so that the baffle 9 drives the rotating shaft 3 to rotate, thereby driving the stirring rod 10 to rotate, so that the stirring rod 10 stirs the sewage.

[0025] The top of the box body 1 is fixedly connected to the dosing box 4. A feed port is provided on the top of the dosing box 4. A plug 8 is installed in the feed port. A through port 16 is provided at the bottom of the dosing box 4. The through port 16 is communicated with the box body 1. The through port 16 corresponds to the rotating shaft 3. The feeding structure includes a spiral conveying shaft 7. The spiral conveying shaft 7 rotates and fits in the dosing box 4. The rotating shaft 3 passes through the through port 16 and is fixedly connected to the spiral conveying shaft 7.

[0026] Specifically, when mixing is performed, the coagulant is poured into the dosing box 4 through the feed port, and then as the rotating shaft 3 rotates, the rotating shaft 3 can drive the spiral conveying shaft 7 to rotate synchronously, thereby sending the coagulant into the box body 1 through the spiral conveying shaft 7, and the coagulant can be mixed with the sewage.

[0027] A first flange 11 is fixed to the lower side of the box body 1, and second flanges 12 are fixed to both ends of the extended mixing cylinder 13. The first flange 11 corresponds to the second flange 12. The first cyclone 14 and the second cyclone 15 are respectively fixed to the two ends of the extended mixing cylinder 13, and the first cyclone 14 and the second cyclone 15 are in opposite directions.

[0028] Specifically, when the mixing time needs to be extended, the extended mixing drum 13 can be fixed to the box body 1 through the first flange 11 and the second flange 12. Multiple extended mixing drums 13 can be connected. Then, the sewage mixed with the coagulant can enter the extended mixing drum 13, and form a vortex after passing through the first cyclone 14 and the second cyclone 15, thereby extending the mixing time of the sewage and the coagulant and ensuring the flocculation effect.

[0029] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
