[0002] Steel mill wastewater treatment flocculants, also known as steel mill wastewater treatment flocculants, are agents specifically designed to treat steel mill wastewater treatment solutions generated during steel production. Their primary function is to destabilize solute, colloid, or suspended particles in aqueous solutions through their specific chemical properties, producing floccules or flocculent precipitates, thereby facilitating subsequent filtration and separation processes.

[0003] During the flocculant production process, the selected raw materials need to be added to the mixer in a certain proportion according to the production formula. At the same time, an appropriate amount of water is added and stirred thoroughly to ensure that the raw materials are evenly mixed.

[0004] However, during the mixing process, since the agitator (such as paddle, anchor, or frame type) is usually fixed to the rotating shaft, a certain gap exists between the agitator and the mixing tank to ensure smooth rotation of the rotating shaft in the mixing tank. As a result, there are some areas in the mixing tank that the agitator cannot reach, namely, the mixing dead spots. The raw materials in these mixing dead spots may not be fully mixed with other raw materials, which in turn affects the production quality of the flocculant. Utility Model Content

[0005] The purpose of the utility model is to provide a production device for a flocculant for a steel dust and sludge washing solution, so as to solve the technical problem in the prior art that there are some places in the stirring tank that cannot be stirred by the agitator, namely, stirring dead corners, and the raw materials in the stirring dead corners may not be fully mixed with other raw materials, thereby affecting the production quality of the flocculant.

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 6 As shown, a production device for a flocculant for a steel dust and sludge washing solution includes a support frame 1, a stirring tank 2, a rotating drum 3, a rotating shaft 4, a first stirring rod 5 and a second stirring rod 6. A plurality of feed ports 7 are evenly opened on the top of the stirring tank 2. A variety of different types of raw materials enter the stirring tank 2 at the same time through the plurality of feed ports 7 evenly opened on the top of the stirring tank 2, ensuring that the raw materials can be evenly distributed in the initial stage, reducing the problem of uneven mixing caused by different raw material addition orders or positions, thereby reducing the difficulty of subsequent mixing.

[0027] The bottom of the mixing tank 2 is fixedly connected to the top of the support frame 1. The rotating drum 3 and the rotating shaft 4 are both connected to the mixing tank 2 in a rotationally coordinated manner, and the rotating shaft 4 is located inside the rotating drum 3. There are multiple first stirring rods 5 and second stirring rods 6, and the first stirring rods 5 are arranged in a matrix on the inside of the rotating drum 3. The second stirring rods 6 are arranged longitudinally on the outside of the rotating shaft 4. The mixing tank 2 is provided with a driving mechanism 8 for driving the rotating drum 3 and the rotating shaft 4 to rotate. Specifically, the rotating drum 3 rotates around the center of the mixing tank 2, and the first stirring rods 5 arranged in a matrix inside the rotating drum 3 are responsible for large-scale stirring and preliminary mixing of the raw materials. The rotating shaft 4 located inside the rotating drum 3 and the second stirring rods 6 arranged longitudinally on the outside further refine the stirring effect.

[0028] A discharge port 9 is provided at the bottom of the stirring tank 2 , and the fully mixed flocculant raw materials are discharged through the discharge port 9 at the bottom of the stirring tank 2 and enter the subsequent processing steps.

[0029] Through the different arrangements and motion trajectories of the first stirring rod 5 and the second stirring rod 6, a more complex stirring flow field is formed, the stirring effect is enhanced, and it is conducive to more complete chemical reactions and physical mixing between the raw materials. At the same time, the stirring dead angle is effectively reduced, so that the raw materials can reach a uniform mixing state more quickly in the stirring tank 2, thereby improving the production efficiency and quality of the flocculant. Through the multiple feed ports 7 evenly opened on the top of the stirring tank 2, a variety of different types of raw materials can enter the stirring tank 2 at the same time, ensuring that the raw materials can be evenly distributed in the initial stage, reducing the problem of uneven mixing caused by different order or position of raw material addition, thereby reducing the difficulty of subsequent mixing.

[0030] refer to Figure 4 and Figure 5 As shown, in some specific embodiments, in order to realize the driving mechanism 8 driving the drum 3 and the rotating shaft 4 to rotate in the mixing tank 2, the driving mechanism 8 includes a driving wheel 10, a driven wheel 11, a synchronous belt 12, a transmission shaft 13, a first gear 14 and a rotary motor 16. The transmission shaft 13 is rotatably arranged in the mixing tank 2, the driving wheel 10 is coaxially fixedly connected to the rotating shaft 4, the driven wheel 11 and the first gear 14 are both coaxially fixedly connected to the transmission shaft 13, the drum 3 is provided with an annular tooth groove 15 meshing with the first gear 14, and the synchronous belt 12 is cooperatively arranged between the driving wheel 10 and the driven wheel 11. This enables the rotating shaft 4 to rotate, not only allowing the second stirring rod 6 on its outer side to penetrate into the raw material for stirring, but also driving the movement of the drum 3 and the first stirring rod 5 through its rotation, forming a more complex flow field, thereby enhancing the coverage of every corner in the mixing tank 2. The rotary motor 16 is fixedly arranged at the top of the mixing tank 2, and the output end of the rotary motor 16 is coaxially fixedly connected to the rotating shaft 4.

[0031] Specifically, when the rotating motor 16 receives a start signal, its output end begins to rotate. Since the output end of the rotating motor 16 is coaxially fixedly connected to the rotating shaft 4, the rotating shaft 4 also begins to rotate. As the rotating shaft 4 rotates, it also drives the driving pulley 10, which is coaxially fixedly connected to it, to rotate. The driving pulley 10 is connected to the driven pulley 11 by a timing belt 12. When the driving pulley 10 rotates, the friction of the timing belt 12 causes the driven pulley 11 to also rotate. Since the driven pulley 11 is coaxially fixedly connected to the transmission shaft 13, the rotation of the driven pulley 11 drives the rotation of the transmission shaft 13. At the same time, a first gear 14 is coaxially fixed to the transmission shaft 13, so that the first gear 14 rotates with the transmission shaft 13. The rotating drum 3 is provided with an annular tooth groove 15 that meshes with the first gear 14. When the first gear 14 rotates, the meshing action with the annular tooth groove 15 drives the rotating drum 3 to rotate about the center of the mixing tank 2. As the shaft 4 rotates, the second stirring rod 6 on its outer side penetrates deep into the raw materials to stir them. Simultaneously, the rotation of the drum 3 drives the movement of the first stirring rod 5 on its inner side, creating a dual stirring effect. This dual stirring not only enhances the stirring force but also creates a more complex stirring flow field, facilitating thorough mixing of the raw materials and uniform chemical reactions.

[0032] refer to Figure 6 and Figure 2 As shown, in some specific embodiments, in order to ensure the smooth progress of the production process and the sealing of the equipment, a sealing end cover 17 is provided at the port of the feed port 7. After the raw materials are put in, the sealing end cover 17 can close the feed port 7 in time to prevent the splashing of the raw materials or the entry of external impurities during the stirring process. The sealing end cover 17 and the feed port 7 are usually connected by threaded connection, snap connection or flange connection to ensure the tightness and sealing of the connection. When it is necessary to add raw materials, the sealing end cover 17 can be easily opened and the raw materials can be put into the mixing tank 2; after the feeding is completed, the sealing end cover 17 can be quickly closed to restore the sealing state of the equipment. A discharge pipe 18 is provided at the port of the discharge port 9. The discharge pipe 18 is used to smoothly discharge the flocculant raw materials that are evenly mixed in the mixing tank 2 and enter the subsequent processing steps.

[0033] refer to Figure 2 and Figure 3 As shown, in some specific embodiments, in order to realize the rotation of the rotating drum 3 and the rotating shaft 4 in the mixing tank 2, an annular rotating groove 19 is provided at the bottom of the mixing tank 2, and the bottom of the rotating drum 3 is rotatably connected to the annular rotating groove 19. A rotating hole is provided at the top of the mixing tank 2, and the top of the rotating shaft 4 is rotatably connected to the rotating hole.

[0034] During installation, the bottom of the drum 3 is placed in the annular groove 19 at the bottom of the mixing tank 2 to ensure its stability during rotation. Similarly, the top of the shaft 4 passes through the rotating hole at the top of the mixing tank 2 and is connected to the rotating motor 16.

[0035] refer to Figure 2 As shown, in some specific embodiments, to improve discharge efficiency, the bottom of the mixing tank 2 is funnel-shaped. This funnel-shaped structure helps the raw materials gradually converge to the center of the bottom of the mixing tank 2 during the mixing process, allowing the raw materials to flow out more smoothly during discharge. This reduces the amount of raw materials remaining at the bottom of the mixing tank 2 during discharge, improves discharge efficiency, and reduces cleanup workload.

[0036] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be described in conjunction with specific application scenarios:

[0037] In actual use, first prepare a variety of raw materials corresponding to the various components in the flocculant formulation. Open the sealed end caps 17 of the multiple feed ports 7 uniformly distributed across the top of the mixing tank 2, and simultaneously add the various raw materials through these ports. Because the feed ports 7 are evenly distributed, the raw materials are evenly distributed within the mixing tank 2 from the initial stage, minimizing uneven mixing caused by the order or location of raw material addition. After the materials are added, quickly close the sealed end caps 17 of all feed ports 7 to ensure a tight seal during the mixing process.

[0038] Start the rotary motor 16, and the output end of the rotary motor 16 begins to rotate, and drives the rotating shaft 4 fixedly connected to it coaxially to rotate together. When the rotating shaft 4 rotates, the second stirring rod 6 arranged longitudinally on its outer side penetrates into the interior of the raw material to stir, achieving a preliminary mixing effect. At the same time, the rotating shaft 4 also drives the driven wheel 11 and the transmission shaft 13 to rotate through the synchronous belt 12 transmission mechanism. The first gear 14 on the transmission shaft 13 engages with the annular tooth groove 15 on the inner side of the rotating drum 3, driving the rotating drum 3 to rotate around the center of the mixing tank 2. The rotation of the rotating drum 3 further drives the first stirring rod 5 arranged in a matrix on its inner side to stir, forming a double stirring effect with the rotating shaft 4 and the second stirring rod 6. This double stirring not only enhances the stirring force, but also makes the stirring flow field more complex, which is conducive to the full mixing of the raw materials and the uniform progress of the chemical reaction.

[0039] During the stirring process, chemical reactions or physical mixing occur between the raw materials, forming the desired flocculant. The complex flow field within the stirring tank 2 facilitates the rapid progress of these reactions and the uniform distribution of the products. The different arrangements and motion paths of the first and second stirring rods 5, 6 ensure that the raw materials are fully stirred and mixed in every corner of the stirring tank 2, effectively reducing blind spots.

[0040] When the stirring time reaches a predetermined value or the raw materials are evenly mixed, the motor 16 is stopped. The discharge port 9 at the bottom of the mixing tank 2 is opened, and the evenly mixed flocculant raw materials flow rapidly out through the funnel-shaped structure at the bottom of the mixing tank 2 and enter the subsequent processing steps. The funnel-shaped structure helps reduce the amount of raw materials remaining at the bottom of the mixing tank 2 during discharge, thereby improving discharge efficiency.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
