Description

Technical Field

[0001] This utility model relates to the field of flocculation device technology, and in particular to a high-efficiency flocculation device. Background Technology

[0002] Copolymers are polymers formed by the polymerization reaction of two or more monomers. These polymers contain two or more monomer units and are usually called copolymers. In the copolymer production process, the emulsion, flocculant, and softened water in the emulsion storage tank are continuously fed into the flocculation device in the required proportion. Flocculation is achieved by hydraulic or mechanical stirring to disturb the water body, generating velocity gradients or eddies, which promotes particle collision and aggregation. The goal is to achieve flocculation between suspended particles in the water or between suspended particles and the coagulant. Existing technology publication number CN220334892U proposes a high-efficiency electrocoagulation device, including an electrolytic cell, a stirring assembly, a lifting assembly, and an electrolysis assembly. The stirring assembly is installed inside the electrolytic cell, and the lifting assembly is installed at the upper part of the outer side of the electrolytic cell. The upper end of the lifting assembly is connected to the stirring assembly, and the electrolysis assembly is installed at the upper end of the stirring assembly. However, because the stirring block is horizontally positioned, the particles generated after flocculation are easily adsorbed and accumulated on the stirring block, affecting the formation and discharge of flocs, resulting in poor mixing quality and reduced flocculation efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a high-efficiency flocculation device that improves stirring quality, increases flocculation efficiency, and prevents flocs from adhering to the inner wall.

[0004] This utility model discloses a high-efficiency flocculation device, comprising a flocculation tank, a feeding component, an agitation component, a scraping component, and a discharge component. The feeding component is connected to the top of the flocculation tank. The agitation component is installed inside the flocculation tank to mix and agitate the emulsion containing flocculant. The scraping component is installed on the agitation component to clean the inner wall of the flocculation tank. The discharge component is connected to the bottom of the flocculation tank to discharge the mixed and flocculated liquid. The emulsion containing flocculant is evenly distributed into the flocculation tank through the feeding component for initial mixing. The agitation component further agitates the water, generating velocity gradients or vortices, promoting particle collision and aggregation, and causing flocculation between suspended particles in the water or between suspended particles and the coagulant, thereby improving flocculation efficiency. At the same time, the scraping component cleans the inner wall of the flocculation tank to prevent flocculants from adhering to the inner wall, and the discharge component can discharge the flocculants, improving the mixing quality.

[0005] Preferably, the feeding assembly includes a feeding pipe, an annular pipe, and a guide plate. The output end of the feeding pipe is connected to the annular pipe, and multiple distribution pipes are evenly arranged at the bottom of the annular pipe. The output ends of the distribution pipes are respectively connected to the top of the flocculation tank and communicate with the inside of the flocculation tank. The guide plate is installed on the upper inner wall of the flocculation tank and has multiple flow holes. The emulsion with added flocculant is fed into the annular pipe through the feeding pipe and evenly distributed into the flocculation tank through the multiple distribution pipes. The guide plate can guide the emulsion added to the flocculation tank, and the flow holes can disperse and mix the emulsion with added flocculant, thus performing preliminary mixing of the emulsion.

[0006] Preferably, the agitation assembly includes a gearbox, a drive motor, a main shaft, a first spiral agitator, and a second spiral agitator. The gearbox is located above the flocculation tank, with its input end connected to the output end of the drive motor. The output end of the gearbox is connected to the main shaft, which is rotatably mounted inside the flocculation tank. The first spiral agitator is mounted on the upper part of the main shaft, and the second spiral agitator is mounted on the lower part of the main shaft. The spiral directions of the first and second spiral agitators are opposite. When the drive motor is started, it drives the main shaft to rotate via the gearbox. The main shaft drives the first and second spiral agitators to rotate, agitating the water. The first spiral agitator pushes the upper emulsion downwards, while the second spiral agitator pushes the lower emulsion upwards. This causes the emulsion to collide and aggregate in the middle of the flocculation tank, resulting in flocculation between suspended particles in the water or between suspended particles and the coagulant, thereby improving the flocculation efficiency.

[0007] Preferably, it also includes multiple stirring rods and multiple sets of stirring support rods. The multiple stirring rods are axially and evenly connected in the middle of the main shaft, and multiple stirring support rods of different lengths are installed on the stirring rods. When the main shaft rotates, it drives the stirring rods to rotate, thereby driving the stirring support rods to rotate, stirring and agitating the emulsion in the flocculation tank, further promoting the collision and aggregation of particles, so that flocculation occurs between suspended particles in the water or between suspended particles and coagulant.

[0008] Preferably, the scraping assembly includes multiple sets of support rods, multiple cylindrical rods, multiple support rods, multiple sliding plates, multiple springs, multiple scrapers, and multiple sets of reinforcing rods. Multiple sets of support rods and stirring rods are alternately installed on the outer wall of the main shaft in the middle. A cylindrical rod is fixedly installed in the middle of the support rod, and the cylindrical rod is slidably installed on the support rod inside. A sliding plate is installed at one end of the support rod inside the cylindrical rod, and the sliding plate is slidably installed inside the cylindrical rod. A spring is installed inside the cylindrical rod, and one end of the spring is connected to the sliding plate. A scraper is installed at the end of the support rod away from the cylindrical rod, and reinforcing rods are connected to the upper and lower ends of the scraper. The other end of the reinforcing rod is connected to the upper and lower sides of the support rod. When the main shaft rotates, the support rods and cylindrical rods drive the support rods to rotate, which in turn drives the scrapers to rotate, scraping and cleaning the inner wall of the flocculation tank to prevent flocculants from adhering to the inner wall. The springs push the sliding plates and support rods to slide inside the cylindrical rods, ensuring close contact between the scrapers and the inner wall of the flocculation tank. Simultaneously, the support rods and cylindrical rods can cooperate with the stirring rods and stirring support rods to agitate and disturb the emulsion in the middle.

[0009] Preferably, the discharge assembly includes a connecting pipe, a discharge cylinder, an output shaft, spiral discharge blades, a discharge motor, and a discharge pipe. The connecting pipe is connected to the bottom of the flocculation tank and is equipped with a valve. The output end of the connecting pipe is connected to the discharge cylinder. The output shaft is rotatably mounted in the middle of the discharge cylinder. The input end of the output shaft passes through the left side wall of the discharge cylinder and is connected to the output end of the discharge motor. The discharge motor is mounted on the left side wall of the discharge cylinder. Spiral discharge blades are installed on the outer wall of the output shaft. The discharge pipe is connected to the lower part of the right side wall of the discharge cylinder and is equipped with a discharge valve. After the emulsion is mixed, the valve and the discharge valve are opened, and the material is input into the discharge cylinder through the connecting pipe. The discharge motor is started to drive the output shaft to rotate. The output shaft drives the spiral discharge blades to rotate and discharge the flocs, thereby improving the discharge efficiency.

[0010] Preferably, the assembly also includes a dispersing plate, a support platform, and a support turntable. The dispersing plate is fixedly installed on the upper outer wall of the main shaft and located below the guide plate. The support platform is fixedly installed on the top of the flocculation tank. The gearbox is fixedly connected to the top of the support platform. A support rotating cavity is opened in the middle of the support platform. The support turntable is rotatably installed in the support rotating cavity. The main shaft rotates through the middle of the support platform, and the middle of the support turntable is fixedly connected to the outer wall of the main shaft. When the main shaft rotates, it drives the support turntable to rotate in the support rotating cavity, providing support and guidance for the main shaft and ensuring stability. When the main shaft rotates, it drives the dispersing plate to rotate, dispersing the added emulsion and ensuring the mixing effect of the emulsion.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the emulsion with added flocculant is evenly distributed into the flocculation tank through the feeding component to initially mix the emulsion. The stirring component further agitates the water body, generating a velocity gradient or vortex, which promotes the collision and aggregation of particles, causing flocculation between suspended particles in the water or between suspended particles and coagulant, thereby improving the flocculation efficiency. At the same time, the scraping component cleans the inner wall of the flocculation tank to prevent flocculants from adhering to the inner wall, and the discharge component can discharge the flocculants, thus improving the mixing quality.

Multiple distribution pipes are evenly arranged at the bottom of the annular pipe 3, and the output ends of the distribution pipes are respectively connected to the top of the flocculation tank 1 and communicate with the inside of the flocculation tank 1. The guide plate 5 is installed on the upper inner wall of the flocculation tank 1, and multiple flow holes are opened on the guide plate 5. A gearbox 6 is located above the flocculation tank 1. The input end of the gearbox 6 is connected to the output end of the drive motor 7, and the output end of the gearbox 6 is connected to a main shaft 8. The main shaft 8 is rotatably installed inside the flocculation tank 1. A first spiral stirring blade 9 is installed on the upper part of the main shaft 8, and a second spiral stirring blade 10 is installed on the lower part of the main shaft 8. The spiral stirring blade 9 and the second spiral stirring blade 10 have opposite spiral directions. Multiple stirring rods 11 are axially and evenly connected in the middle of the main shaft 8. Multiple stirring support rods 12 of different lengths are installed on the stirring rods 11. Multiple sets of support rods 15 are alternately installed on the outer wall of the middle part of the main shaft 8 with the stirring rods 11. A cylindrical rod 16 is fixedly installed in the middle of the support rod 15. The cylindrical rod 16 is slidably installed on the support rod 17 inside. A sliding plate 18 is installed at one end of the support rod 17 inside the cylindrical rod 16. The sliding plate 18 is slidably installed inside the cylindrical rod 16.

The other end of the reinforcing rod 21 is connected to the upper and lower sides of the support rod 17.

[0021] The emulsion with added flocculant is fed into the annular pipe 3 through the feed pipe 2, and then evenly distributed into the flocculation tank 1 through multiple distribution pipes. The guide plate 5 guides the emulsion added to the flocculation tank 1, and the emulsion with added flocculant is dispersed and mixed through the flow holes. After initial mixing, the drive motor 7 is started, which drives the main shaft 8 to rotate through the gearbox 6. The main shaft 8 drives the first spiral stirring blade 9 and the second spiral stirring blade 10 to rotate and agitate the water. The first spiral stirring blade 9 pushes the upper part of the emulsion downward, while the second spiral stirring blade 10 pushes the lower part of the emulsion upward. This causes the emulsion to collide and agglomerate in the middle of the flocculation tank 1, resulting in flocculation between suspended particles in the water or between suspended particles and the coagulant, thereby improving the flocculation efficiency. When the main shaft 8 rotates, it drives the stirring rod 11 to rotate, which in turn drives the stirring support rod 12 to rotate, stirring and agitating the emulsion in the flocculation tank 1, further promoting the collision and aggregation of particles, causing flocculation between suspended particles in the water or between suspended particles and coagulant. When the main shaft 8 rotates, it drives the support rod 17 to rotate through the support rod 15 and the cylinder rod 16. The support rod 17 drives the scraper 20 to rotate, scraping and cleaning the inner wall of the flocculation tank 1 to prevent flocculants from adhering to the inner wall. The spring 19 pushes the sliding plate 18 and the support rod 17 to slide inside the cylinder rod 16, ensuring close contact between the scraper 20 and the inner wall of the flocculation tank 1. At the same time, the support rod 15 and the cylinder rod 16 can cooperate with the stirring rod 11 and the stirring support rod 12 to stir and agitate the emulsion in the middle.

[0024] After the emulsion is mixed, the valve and discharge valve are opened, and the material is input into the discharge cylinder 23 through the connecting pipe 22. The discharge motor 26 is started to drive the output shaft 24 to rotate. The output shaft 24 drives the spiral discharge blades 25 to rotate and discharge the flocculent material, which improves the discharge efficiency. When the main shaft 8 rotates, it drives the support turntable 14 to rotate in the support cavity to support and guide the main shaft 8 and ensure stability. When the main shaft 8 rotates, it drives the dispersing plate 4 to rotate, which disperses the added emulsion and ensures the mixing effect of the emulsion.

[0025] like Figures 1 to 5 As shown, this utility model discloses a high-efficiency flocculation device. During operation, an emulsion containing flocculant is fed into an annular pipe 3 via a feed pipe 2, and then evenly distributed into a flocculation tank 1 through multiple distribution pipes.

The drive motor 7, via a gearbox 6, drives the main shaft 8 to rotate. The main shaft 8 drives the first spiral stirring blade 9 and the second spiral stirring blade 10 to rotate, agitating the water. The first spiral stirring blade 9 pushes the upper emulsion downwards, while the second spiral stirring blade 10 pushes the lower emulsion upwards, causing the emulsion to collide and aggregate in the middle of the flocculation tank 1, resulting in flocculation between suspended particles in the water or between suspended particles and the coagulant. The rotation of the main shaft 8 drives the dispersion plate 4 to rotate, further dispersing the added emulsion. The stirring rod 11 rotates, thereby driving the stirring support rod 12 to rotate, stirring and agitating the emulsion in the flocculation tank 1, further promoting the collision and aggregation of particles. When the main shaft 8 rotates, it drives the support rod 17 to rotate through the support rod 15 and the cylinder rod 16.
