Description

Technical Field

[0001] This utility model belongs to the field of hot-dip galvanizing technology, specifically relating to hot-dip galvanizing tanks, and more particularly to hot-dip galvanizing waste residue and wastewater treatment tanks. Background Technology

[0002] Hot-dip galvanizing is an important means of corrosion protection for steel products. During its production, a large amount of acidic wastewater containing high concentrations of heavy metal ions such as zinc and iron is generated. This wastewater is usually collected in a special treatment pond and needs to be neutralized, precipitated, and treated before it can be discharged or reused.

[0003] Currently, the mainstream treatment method for hot-dip galvanizing wastewater is chemical precipitation, which involves adding alkaline agents (such as lime or liquid alkali) and flocculants to the treatment tank to cause heavy metal ions to form hydroxide precipitates, followed by purification through solid-liquid separation. However, traditional methods of adding chemicals have significant drawbacks: powdered chemicals are typically added to the tank manually or using simple single-point dosing equipment. This method easily leads to the accumulation of powder in localized areas of the tank, forming "mountain-like" clumps.

[0004] Powder accumulation can cause a series of problems: First, the slow dissolution of the reagent inside the clumps results in low reaction efficiency with wastewater, prolonging the treatment time and reducing the utilization rate of the tank; second, undissolved reagents sink to the bottom of the tank, wasting the effective ingredients and increasing operating costs; third, excessively high local pH values ​​may cause the already formed heavy metal hydroxide precipitates to redissolve (such as the redissolution of amphoteric hydroxide Zn(OH)2 under strong alkali), which in turn affects the treatment efficiency.

[0005] Therefore, how to avoid regional accumulation during drug delivery is a technical problem that urgently needs to be solved in this field.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0029] Research has revealed shortcomings in existing technologies: the mainstream treatment method for hot-dip galvanizing wastewater is chemical precipitation, which involves adding alkaline agents (such as lime or liquid alkali) and flocculants to the treatment tank to cause heavy metal ions to precipitate as hydroxides, followed by purification through solid-liquid separation. However, traditional methods of adding chemicals have significant drawbacks: they typically involve manual dumping or simple single-point dosing equipment to add powdered chemicals into the tank, which easily leads to the accumulation of powder in localized areas, forming "hill-like" clumps.

[0030] Powder accumulation can cause a series of problems: First, the slow dissolution of the reagent inside the clumps results in low reaction efficiency with wastewater, prolonging the treatment time and reducing the utilization rate of the tank; second, undissolved reagents sink to the bottom of the tank, wasting the effective ingredients and increasing operating costs; third, excessively high local pH values ​​may cause the already formed heavy metal hydroxide precipitates to redissolve (such as the redissolution of amphoteric hydroxide Zn(OH)2 under strong alkali), which in turn affects the treatment efficiency.

[0031] Therefore, how to avoid regional accumulation during drug delivery is a technical problem that urgently needs to be solved in this field.

[0032] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] like Figures 1 to 2 As shown, some embodiments provide a hot-dip galvanizing wastewater treatment tank, including: a treatment tank 1; the treatment tank 1 is the core structure of the hot-dip galvanizing wastewater treatment system, made of corrosion-resistant concrete or steel, and the inner wall may be lined with an anti-corrosion layer such as fiberglass or PP board to resist the erosion of acidic wastewater; used to store and neutralize acidic wastewater containing high concentrations of heavy metal ions such as zinc and iron from the production process.

[0036] The gantry 2 is erected above the treatment pool 1. The gantry 2 is a support structure that can move along the length of the treatment pool 1. It is made of steel sections (such as I-beams and H-beams) welded or bolted together and has sufficient rigidity and strength to support the spreading mechanism 3 and the weight of the agent it carries.

[0037] The bottom of the gantry 2 is equipped with wheels, which enable it to move smoothly along the tracks laid on both sides of the treatment tank 1 (not shown in the figure). This setup allows the spreading mechanism 3 to cover the entire liquid surface area of ​​the treatment tank 1, achieving a fundamental shift from "fixed-point addition" to "mobile uniform spreading" and overcoming the problem of excessively high local concentration caused by traditional fixed-point addition. It should be further noted that the moving speed of the gantry 2 can be adjusted by frequency conversion according to the treatment requirements.

[0038] The spreading mechanism 3 is installed on the crossbeam of the gantry frame 2 and moves with the gantry frame 2 to add chemicals into the treatment tank 1. The spreading mechanism 3 is fixed to the crossbeam of the gantry frame 2 by connecting parts (such as U-bolts or special supports) and moves longitudinally (in the length direction of the treatment tank 1) together with the gantry frame 2. It quantitatively and evenly spreads the powdered or granular chemicals (such as lime, sodium hydroxide, flocculant, etc.) stored in the feed hopper 32 onto the wastewater surface of the treatment tank 1.

[0039] The spreading mechanism 3 integrates the functions of conveying and distributing the agent, and together with the moving gantry 2, it realizes dynamic and decentralized addition in a two-dimensional plane (length and width direction). This is significantly different from the traditional manual dumping or fixed conveyor addition method, and avoids the situation of the agent accumulating into a "small mountain" in a certain area of ​​the pool from the source.

[0040] The feeding mechanism 3 includes: a spiral feeding cylinder 33, which has several discharge ports 34 facing the treatment pool 1; the spiral feeding cylinder 33 is a closed cylindrical structure, and is equipped with a spiral feeding paddle (commonly known as an auger) driven by the driving component 31; the cylinder body is made of wear-resistant and corrosion-resistant steel or polymer material.

[0041] The spiral feed cylinder 33 is used to receive the agent from the feed hopper 32 and push the agent from the feed end to the other end stably and continuously through the rotation of the propeller, so as to realize the horizontal conveying of the material. The key is that multiple discharge ports 34 are opened at certain intervals along the bottom or side of the spiral feed cylinder 33 towards the liquid surface of the treatment tank 1.

[0042] The dimensions and spacing of these discharge ports 34 are precisely calculated to divide the continuous material flow into multiple smaller, discrete discharge points. This design transforms single-point centralized dosing into multi-point linear distribution dosing, initially widening the range of agent landing points in the width direction of the pool. Compared with existing technologies that may have only one discharge port or directly dosing through a hose, the design of multiple discharge ports 34 is the first important measure to achieve uniform distribution.

[0043] The discharge extension pipe 35 is set on the edge of the discharge port 34 and extends towards the treatment tank 1. The discharge extension pipe 35 is a key channel connecting each discharge port 34 to the wastewater surface. Its first end is fixedly installed on the edge of the discharge port 34, and its tail end extends downward, close to but usually not in contact with the liquid surface, to prevent wastewater backflow or scaling and blockage.

[0044] Each discharge port 34 is equipped with a corresponding discharge extension pipe 35. Its main functions are threefold: first, to guide the powdered agent to fall along a predetermined path, reducing interference from lateral airflow (such as wind), preventing dust from flying, and improving the working environment; second, to bring the drop point of the agent closer to the liquid surface, and even adjust its immersion depth below the liquid surface as needed, promoting rapid contact between the agent and the wastewater; and third, to cooperate with multiple discharge ports 34 to form a series of parallel and evenly spaced dosing lines in the pool when the gantry 2 moves, thereby forming a uniform dosing network in the length and width directions of the pool, greatly increasing the contact area between the agent and the wastewater.

[0045] The discharge extension pipe 35 includes a corrugated pipe 351 and a bell pipe 352 located at the tail end of the corrugated pipe 351; the head end of the corrugated pipe 351 is connected to the discharge port 34; the corrugated pipe 351 is a flexible tubular element with a corrugated wall, which gives it a certain degree of flexibility and length adjustment capability; this makes installation more convenient and can compensate for possible positional errors between the gantry 2, the spiral feed cylinder 33 and the liquid surface; more importantly, the operator can manually adjust the degree of bending or extension length of the corrugated pipe 351 according to the change of liquid level, so as to always maintain the optimal distance between the discharge pipe outlet and the liquid surface.

[0046] The horn tube 352 is connected to the tail end of the corrugated tube 351. Its opening diameter gradually increases from the connection end to the outlet end, forming a horn shape. This structure helps to reduce the adhesion and accumulation of powder materials at the tube opening, reducing the risk of blockage. At the same time, the horn opening can disperse the falling powder, allowing it to enter the wastewater in a more dispersed state, avoiding the formation of concentrated material columns, and further promoting the rapid dispersion and dissolution of the agent.

[0047] At least one miniature vibration motor 353 is provided on the outer wall of the horn tube 352; the miniature vibration motor 353 is an active unblocking device to prevent powder from adhering, bridging or blocking at the tube opening, especially at the horn opening; it is usually fixed to the outer wall of the horn tube 352 by a mounting plate.

[0048] When the vibrating motor 353 is working, it generates high-frequency, low-amplitude mechanical vibrations, which are transmitted to the horn tube 352 and the end of the corrugated tube 351 connected to it. This vibration can effectively break the adsorption force between the powder particles and the tube wall, as well as the electrostatic force between the particles, making the material loose and allowing it to fall smoothly from the tube opening and disperse. This device is particularly important for hygroscopic or poorly fluid agents, as it can significantly improve the reliability and continuity of feeding and avoid interruptions or uneven distribution caused by tube blockage.

[0049] A drive unit 31 is provided at one end of the spiral feed cylinder 33, which is connected to the spiral feed paddle inside the spiral feed cylinder 33. The drive unit 31 is usually an electric motor with a reducer (such as a cycloidal pinwheel reducer motor or a gear reducer motor), which is connected to the shaft end of the spiral feed paddle through a coupling to provide it with rotational power. The rotational speed of the drive unit 31 (i.e., the rotational speed of the spiral feed paddle) can be precisely controlled by a frequency converter. By controlling the rotational speed of the spiral, the dosage of the chemical pushed out of the feed hopper 32 per unit time can be precisely controlled, thereby achieving accurate metering and adjustment of the dosage. This is the key to achieving automated dosing. Operators can adjust the dosage in real time according to the water quality and flow rate of the wastewater to ensure stable treatment effect and save chemical consumption.

[0050] A feed hopper 32 is provided at one end of the spiral feed cylinder 33. The feed hopper 32 is a funnel-shaped container for storing the agent to be added, and is located above the feed end of the spiral feed cylinder 33. The feed hopper 32 is designed to meet the continuous addition requirements for a certain period of time and reduce the feeding frequency. The outlet of the feed hopper 32 is connected to the inlet of the spiral feed cylinder 33. The agent automatically flows into the spiral feed cylinder 33 under the action of gravity and is conveyed forward by the rotating spiral feed paddle.

[0051] It should be further noted that the hopper is equipped with a screen (not shown in the figure) to prevent large, clump-like materials from entering the feeding system and causing blockages; the design of the feed hopper 32 ensures a continuous and stable supply of materials to the screw feeder system.

[0052] Some embodiments provide a hot-dip galvanizing wastewater treatment tank, including: a material spreading mechanism 3; the material spreading mechanism 3 includes: a spiral feeding cylinder 33, which has a plurality of discharge ports 34 facing the treatment tank 1; a discharge extension pipe 35, which is disposed on the edge of the discharge ports 34 and extends towards the treatment tank 1; the discharge extension pipe 35 includes a corrugated pipe 351 and a horn pipe 352 disposed at the tail end of the corrugated pipe 351; the head end of the corrugated pipe 351 is connected to the discharge ports 34; at least one miniature vibration motor 353 is disposed on the outer wall of the horn pipe 352.

[0053] One end of the spiral feed cylinder 33 is provided with a drive unit 31, which is connected to the spiral feed paddle inside the spiral feed cylinder 33; one end of the spiral feed cylinder 33 is provided with a feed hopper 32; the spreading mechanism 3 is adapted to move along the length direction of the treatment tank 1.

[0054] Overall workflow: After the hot-dip galvanizing wastewater is introduced into the treatment tank 1, the system starts to work. First, powdered agents (such as lime) are added to the feed hopper 32. The drive unit 31 is started, which drives the spiral feeder in the spiral feed cylinder 33 to rotate, and pushes the agent from the feed hopper 32 to the other end of the cylinder stably. During this process, the agent is evenly distributed to each discharge port 34. At the same time, the drive device of the gantry 2 is started, which drives the entire spreading mechanism 3 to move slowly along the length of the treatment tank 1.

[0055] After the agent flows out from each discharge port 34, it enters the corresponding discharge extension pipe 35; the micro vibration motor 353 works continuously to prevent the powder from clogging the opening of the horn pipe 352; after being guided and diffused by the corrugated pipe 351 and the horn pipe 352, the agent falls into the wastewater of the treatment tank 1 in a dispersed state; because the gantry 2 is moving and has multiple discharge points, the agent is evenly spread in different positions on the entire surface of the tank, rather than being concentrated in a certain point.

[0056] This dynamic, distributed dosing method ensures that the reagent comes into contact with a large volume of water as soon as it enters the wastewater, dissolves rapidly, and undergoes a neutralization reaction, avoiding local supersaturation or a sharp increase in pH. Heavy metal ions can quickly and uniformly generate hydroxide precipitates, improving reaction efficiency, shortening treatment time, and increasing the utilization rate of treatment tank 1. At the same time, the reagent is fully utilized, waste is reduced, operating costs are lowered, and the risk of redissolution of amphoteric hydroxides (such as Zn(OH)2) due to local strong alkali is avoided.

[0057] Overall beneficial effects: 1. By setting up a movable gantry 2 and a spreading mechanism 3 installed on it, the spreading point can move and cover the entire liquid surface of the treatment tank 1 in a two-dimensional plane, which fundamentally changes the fixed-point addition mode. 2. By setting multiple discharge ports 34 on the spiral feed cylinder 33, the ability to linearly distribute the dosing at multiple points in the width direction of the pool is obtained, and the agent is initially dispersed. 3. By setting up a discharge extension pipe 35 connecting each discharge port 34, the agent can be accurately guided to a position close to the liquid surface for addition, reducing dust and drop point deviation; 4. By setting up a feeding extension pipe 35 including a corrugated pipe 351 and a horn pipe 352, the adjustability of the pipe opening length and angle and the feeding diffusion effect are obtained, which further promotes the dispersion of the agent. 5. The miniature vibration motor 353 installed on the horn tube 352 improves the smoothness and reliability of material feeding and effectively prevents powder clogging. 6. By setting up a screw feeding mechanism controlled by drive component 31, continuous, precise and adjustable control of the dosage of the agent is realized, laying the foundation for automated operation.

[0058] In summary, through the synergistic effect of the above features, the uniformity of reagent distribution, dissolution rate and reaction efficiency in wastewater are significantly improved, reagent waste and operating costs are reduced, precipitation and redissolution problems caused by excessively high local pH are avoided, and the treatment effect and stability of hot-dip galvanizing wastewater are enhanced.
