Description

Technical Field

[0001] This utility model belongs to the field of algae coagulation treatment technology, and specifically relates to an algae coagulation device. Background Technology

[0002] Currently, eutrophication is becoming increasingly severe in most rivers, with cyanobacteria blooms occurring in these water bodies. These cyanobacteria consume large amounts of oxygen, severely impacting aquatic life and ecosystems, and also affecting people's lives and livelihoods. To address this, specialized equipment is typically used to separate the water from the cyanobacteria. This separation process is complex, requiring the use of coagulation devices to rapidly mix the algae-laden water with coagulants.

[0003] The existing Chinese patent with publication number CN219751966U discloses an air flotation algae removal device for water environment treatment, including: a mounting box with two sets of placement plates fixedly installed on the outside; a mixing mechanism including a rotating rod, a stirring rod, and a second motor; a baffle fixedly installed on the inside of the mounting box; a rotating rod rotatably installed between the baffle and the mounting box; multiple sets of stirring rods fixedly installed on the outer wall of the rotating rod; a second motor fixedly installed on the outside of the baffle; an installation hole opened on the outside of the baffle; the rotating rod extending to the outside of the baffle through the installation hole; and the output shaft of the second motor fixedly installed on the rotating rod through a coupling. By controlling the start of the second motor, the rotating rod can be driven to rotate, causing the stirring rod to rotate and mix the coagulant, accelerating the coagulation of algae and facilitating its collection.

[0004] Regarding the aforementioned technologies, the inventors have discovered at least the following problems: the mixing mechanism uses a single stirring method, resulting in poor mixing effect and reduced coagulation efficiency of algae. Utility Model Content

[0005] The purpose of this invention is to provide an algae coagulation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an algae coagulation device, comprising a coagulation tank and a stirring mechanism, wherein the stirring mechanism comprises a support ring rotatably mounted on the outer wall of the coagulation tank and a driving component for driving the support ring to rotate, a U-shaped frame is fixedly connected to the top of the support ring, two symmetrically distributed stirring rods are rotatably mounted on the bottom of the U-shaped frame, a plurality of stirring blades are fixedly connected to the surface of the stirring rods, a first gear is fixedly connected to the upper end of the stirring rods, a support column is fixedly connected inside the coagulation tank, and a second gear meshing with the first gear is fixedly connected to the upper end of the support column.

[0007] In a preferred embodiment, the driving component includes a motor fixedly mounted on the outer wall of the concrete tank, a third gear fixedly connected to the output end of the motor, and a gear ring meshing with the third gear fixedly sleeved on the support ring.

[0008] In a preferred embodiment, an annular groove is provided on the inner circumference of the support ring, and a guide ring with an annular groove sliding fit is provided on the outer wall of the concrete bucket.

[0009] In a preferred embodiment, a bushing is embedded in the middle of the U-shaped frame, and the upper end of the support column extends movably through the bushing.

[0010] In a preferred embodiment, an annular jet pipe is fixedly installed at the bottom of the outer wall of the coagulation tank, and a plurality of jet nozzles extending into the coagulation tank are fixedly connected to the inner circumference of the annular jet pipe.

[0011] In a preferred embodiment, a discharge pipe is fixedly connected to the bottom of the coagulation tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This algae coagulation device, through the setting of the stirring mechanism, can activate the drive component to drive the support to rotate around the coagulation tank during stirring and mixing. This causes the support ring to drive the U-shaped frame to rotate at the top of the coagulation tank. The U-shaped frame drives two stirring rods to rotate inside the coagulation tank. The stirring rods stir the mixture inside the coagulation tank. When the stirring rods rotate, they drive the first gear to rotate around the second gear. Since the second gear does not rotate, the first gear will rotate on its own axis when it rotates around the second gear. The rotation of the first gear drives the stirring rod to rotate on its own axis, so that the stirring rod drives the stirring blades to finely stir the mixture. This increases the stirring methods, improves the stirring and mixing effect, and thus improves the coagulation efficiency of algae.

[0014] This algae coagulation device, through the setting of annular jet pipe and jet nozzle, allows the air pump to be activated to blow air into the annular jet pipe during coagulation, and air to be blown into the coagulation tank through the jet nozzle of the annular jet pipe. The air bubbles are used to float the algae, thereby improving the algae removal efficiency. Attached Figure Description

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-3 This utility model provides an algae coagulation device, including a coagulation tank 1 and a stirring mechanism 2. The stirring mechanism 2 includes a support ring 21 rotatably mounted on the outer wall of the coagulation tank 1 and a driving component 22 for driving the support ring 21 to rotate. A U-shaped frame 23 is fixedly connected to the top of the support ring 21, and two symmetrically distributed stirring rods 24 are rotatably mounted on the bottom of the U-shaped frame 23. Several stirring blades 25 are fixedly connected to the surface of the stirring rods 24, and a first gear 26 is fixedly connected to the upper end of the stirring rods 24. A support column 27 is fixedly connected inside the coagulation tank 1, and a second gear 28 that meshes with the first gear 26 is fixedly connected to the upper end of the support column 27. Through the setting of the stirring mechanism 2, the device can be activated during mixing. The driving component 22 drives the support ring 21 to rotate around the coagulation tank 1, causing the support ring 21 to drive the U-shaped frame 23 to rotate at the top of the coagulation tank 1. The U-shaped frame 23 drives the two stirring rods 24 to rotate inside the coagulation tank 1. The stirring rods 24 stir the mixture inside the coagulation tank 1. When the stirring rods 24 rotate, they drive the first gear 26 to rotate around the second gear 28. Since the second gear 28 does not rotate, the first gear 26 will rotate on its own axis when it rotates around the second gear 28. The rotation of the first gear 26 drives the stirring rods 24 to rotate on their own axis, causing the stirring rods 24 to drive the stirring blades 25 to finely stir the mixture. This increases the stirring methods, improves the mixing effect, and thus improves the coagulation efficiency of algae.

[0022] Specifically, the driving component 22 includes a motor 221 fixedly installed on the outer wall of the concrete tank 1. The output end of the motor 221 is fixedly connected to a third gear 222. A gear ring 223 that meshes with the third gear 222 is fixedly sleeved on the support ring 21. By setting the driving component 22, the motor 221 can be started to drive the third gear 222 to rotate, which in turn drives the gear ring 223 to rotate, which in turn drives the support ring 21 to rotate.

[0023] The inner circumference of the support ring 21 is provided with an annular groove 29, and the outer wall of the concrete bucket 1 is provided with a guide ring 210 that slides with the annular groove 29. Through the cooperation of the annular groove 29 and the guide ring 210, the support ring 21 can be guided, thereby improving the stability of the support ring 21.

[0024] Among them, a bushing 211 is embedded in the middle of the U-shaped frame 23, and the upper end of the support column 27 is movably inserted through the bushing 211. The bushing 211 can reduce the mutual friction between the U-shaped frame 23 and the support column 27.

[0025] Furthermore, an annular jet pipe 11 is fixedly installed at the bottom of the outer wall of the coagulation tank 1. The annular jet pipe 11 is connected to the outlet of the air pump. Several jet nozzles extending into the coagulation tank 1 are fixedly connected to the inner circumference of the annular jet pipe 11. Through the arrangement of the annular jet pipe 11 and the jet nozzles, during coagulation, the air pump can be activated to blow air into the annular jet pipe 11, and air can be blown into the coagulation tank 1 through the jet nozzles of the annular jet pipe 11. The algae are flotated by the air bubbles, thereby improving the algae removal efficiency.

[0026] Furthermore, a discharge pipe 12 is fixedly connected to the bottom of the coagulation tank 1, through which the coagulated mixture can be discharged.

[0027] The working principle and usage process of this utility model are as follows: Algal wastewater and coagulant are added into the coagulation tank 1. The motor 221 is started to drive the third gear 222 to rotate, which in turn drives the gear ring 223 to rotate. The gear ring 223 then drives the support ring 21 to rotate, which in turn drives the U-shaped frame 23 to rotate at the top of the coagulation tank 1. The U-shaped frame 23 drives the two stirring rods 24 to rotate inside the coagulation tank 1. The stirring rods 24 stir the mixture inside the coagulation tank 1. When the stirring rods 24 rotate, they drive the first gear 26 to rotate around the second gear 28. Since the second gear 28 does not rotate, the first gear 26 will rotate on its own axis when it rotates around the second gear 28. The rotation of the first gear 26 drives the stirring rods 24 to rotate on their own axis, which in turn drives the stirring blades 25 to finely stir the mixture. This increases the stirring methods, improves the mixing effect, and thus improves the coagulation efficiency of the algae.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
