Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an automatic wastewater treatment agent dosing system that prevents agent caking. Background Technology

[0002] Wastewater treatment is a crucial link in modern environmental protection and water resource recycling. Its treatment effectiveness largely depends on the precise addition and efficient mixing of treatment agents (such as flocculants, coagulants, pH adjusters, oxidants, etc.). In wastewater treatment processes, liquid, powdered, or granular chemical agents are typically added to the wastewater to remove pollutants through chemical reactions or physical adsorption.

[0003] The existing chemical dosing structure and method in sewage treatment is relatively simple. Liquid chemicals are usually transported by pipelines and can be distributed at different locations in the sewage treatment equipment as needed. However, solid or powdered treatment agents can usually only be added directly from above the sewage. Solid treatment agents are prone to sinking too quickly and directly to the bottom, while powdered treatment agents are prone to floating on the surface of the sewage and not contacting the lower water layers for a long time. In addition, the dosing of treatment agents is mostly done at a single point or a limited number of points. Once the treatment agent enters the water body, it relies entirely on water flow diffusion or subsequent mechanical stirring. This method can easily lead to localized overconcentration of the agent while the amount of agent in distant areas is insufficient, creating dead zones for dosing. It is difficult for the treatment agent to achieve uniform distribution throughout the pool in a short period of time, which not only affects the treatment effect but also wastes the agent and increases operating costs.

[0004] In addition, solid reagents are prone to caking, which can cause blockages in related structures during transportation and dosing. Furthermore, caking reagents are more likely to settle to the bottom during dosing, affecting the subsequent wastewater treatment effect.

[0005] Based on this, the present invention designs an automatic dosing system for wastewater treatment agents to prevent agent caking, in order to solve the above problems. Summary of the Invention

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1

[0023] Please refer to the accompanying drawings. This invention provides a technical solution: An automatic dosing system for wastewater treatment agents to prevent caking, such as Figure 1 As shown, it includes a water inlet filtration mechanism 100, a gas-liquid conveying mechanism 200 below the water inlet filtration mechanism 100, and a solid material conveying mechanism at the center of the gas-liquid conveying mechanism 200. like Figure 2 , Figure 5 As shown, the gas-liquid conveying mechanism 200 includes a diversion component located in the central area of ​​the inlet filtration mechanism 100, and the sewage input area is the outer annular area of ​​the inlet filtration mechanism 100. The diversion component is set as an annular shape, and multiple conveying components are connected to the bottom. like Figure 2 , Figure 9As shown, the solid material conveying mechanism includes a rotating component 300 that is vertically located at the center of the diversion component and extends out of the diversion component at both ends. The rotating component 300 has a feeding and dispersing component 400 inside. Multiple stirring and mixing components 500 are evenly arranged and rotatably connected along the circumferential direction on the bottom outer side of the rotating component 300. The stirring and mixing components 500 are provided with dispersing holes that communicate with their interiors. The inner end of the stirring and mixing components 500 extends into the rotating component 300 and is correspondingly connected to the bottom of the feeding and dispersing components 400. The inner end of the stirring and mixing components 500 is also connected to a self-drive structure. The self-drive structure is connected to the structure at the lower center of the multi-position conveying component to provide an installation position for the self-drive structure and to provide a limiting effect for the bottom end of the rotating component 300, thereby improving the positional stability of the overall structure.

[0024] This invention achieves an integrated process of sewage filtration, chemical delivery, mixing and stirring, and automatic dosing through the above structure. It integrates sewage filtration, delivery and dosing of different types of treatment agents, and mixing of sewage and chemicals into one unit. By placing the inlet filtration mechanism 100 on the outermost layer, the gas-liquid delivery mechanism 200 in the middle, and the solid material delivery mechanism in the core, a concentric three-dimensional layout is formed, which optimizes space utilization and makes each working unit closely integrated.

[0025] Wastewater first enters from the top of the system and the annular area outside the inlet filtration mechanism 100. The annular area increases the water flow area, initially filtering out large particulate impurities and completing the pretreatment of wastewater.

[0026] For different types of treatment agents, the present invention provides two different delivery and dosing paths.

[0027] For the treatment of fine powders or liquids, the liquid treatment agent is delivered to the diversion component in the gas-liquid conveying mechanism 200 through an external conveying device. The diversion component then directs the liquid into different structures of the multi-position conveying component. The multi-position conveying component is distributed in different positions in the wastewater. In the vertical direction, it is located above, in the middle, and at the bottom of the wastewater. In the horizontal direction, it is located in the center of the wastewater and in the outer annular area. This enables multi-point dosing, avoids local overconcentration or lack of agent, and can quickly establish a uniform agent concentration field.

[0028] In the process of conveying liquid and powdered treatment agents, different external conveying devices can be switched. For liquids, pumps can be used, while for powders, pneumatic conveying can be used. The gas-liquid conveying mechanism 200 can also be used as an aeration structure to convey gas and aerate the wastewater.

[0029] For solid particles or other types of treatment agents with large volume, such as caking treatment agents, they are added through a solid material conveying mechanism. The solid material conveying mechanism is equipped with a feeding dispersion component 400, which rotates with the rotating component 300. The component is initially dispersed before the agent enters the conveying channel to prevent the agent from caking due to accumulation before entering the mixing component 500. When the solid treatment agent moves to the bottom of the feeding dispersion component 400, it moves into multiple mixing components 500 under the action of rotation and is confined inside the mixing components 500. It comes into contact with the sewage through the dispersion holes, and the agent gradually dissolves and seeps out from the dispersion holes instead of being discharged directly in large quantities and settling to the bottom. This prevents the solid agent from accumulating at the bottom of the tank and forming a stubborn crust, and prolongs the contact time between the agent and the water, thus improving the dissolution efficiency.

[0030] Regardless of the dosing method, while the agent is being added to the wastewater, the mixing component 500 revolves around the rotating component 300 in a circular direction, and also rotates on its own axis through a self-rotating drive structure. This generates a composite flow field of axial, radial, and circumferential flow in the water body, which greatly enhances the degree of turbulence, allowing the agent to be fully mixed with the wastewater and improving the treatment effect.

[0031] The gas-liquid conveying mechanism 200 and the solid material conveying mechanism of the present invention have clear division of labor, and their combination can be compatible with substances of different forms. By simply switching external conveying devices such as pumps, fans, and pneumatic conveying systems, it is possible to switch between multiple working modes such as the addition of liquid, powder, and solid three-state treatment agents and aeration, thereby improving the versatility of the equipment.

[0032] The self-driving structure of this invention not only provides power to the stirring assembly but also connects to the lower center of the multi-position conveying assembly, providing limitation and support for the bottom end of the rotating assembly 300. This design avoids the swaying and eccentricity that may occur during the rotation of the long shaft, improving the mechanical stability and durability of the system during long-term operation.

[0033] In summary, this invention saves space through a compact concentric circle layout, ensures full dissolution of the agent through planetary stirring and porous flow restriction, and achieves efficient mixing through multi-point drug distribution, ultimately forming a multifunctional and highly stable wastewater treatment core unit that integrates filtration, conveying, mixing, and aeration.

[0034] Example 2

[0035] The structure of this embodiment is basically the same as that of Embodiment 1, except that, as Figure 2 As shown, the diversion assembly includes a central ring seat 201 fixed at the center of the inlet water filtration mechanism 100, such as... Figure 3 , Figure 7 As shown, the lower part of the central ring seat 201 is provided with an annular flow divider cavity 206, such as... Figure 8 As shown, the top of the annular diversion cavity 206 is connected to a vertical conveying inlet pipe 209, and the bottom is provided with multiple vertical diversion holes 207 along the circumferential direction. Multiple conveying components are connected to the diversion cavity and the diversion holes 207 respectively.

[0036] When conveying liquid treatment agents or gases, the external conveying device is connected to the conveying inlet pipe 209 to feed materials into the annular diversion chamber 206, and feeds materials into different structures in the multi-position conveying assembly through the annular diversion chamber 206 and the diversion hole 207, thus completing the feeding and diversion operations. The above-mentioned assembly uses the annular diversion chamber 206 and the diversion hole 207 to realize multiple outputs, and uses a single conveying inlet pipe 209 to simplify the external connection, thereby realizing the function of one-point input and multi-point three-dimensional addition.

[0037] like Figure 5 As shown, the multi-position conveying assembly includes multiple horizontal first conveying pipes 202 uniformly connected to the lower outer side of the central ring seat 201 along the circumferential direction. Multiple curved second conveying pipes 203 are uniformly arranged below the first conveying pipes 202 along the circumferential direction. The first conveying pipes 202 and the second conveying pipes 203 are evenly and spaced apart in the circumferential direction, so that their positions are staggered and located at different angle positions, so as to distribute more evenly in the sewage treatment equipment and inside the sewage. The bottom inner ends of the multiple second conveying pipes 203 are connected to a connecting plate 204 with an internal cavity. A vertical third conveying pipe 205 is fixed at the top center of the connecting plate 204. The inner end of the first conveying pipe 202 is connected to the annular diversion cavity 206, the top end of the second conveying pipe 203 is connected to the diversion hole 207, and the bottom ends of the second conveying pipe 203 and the third conveying pipe 205 are both connected to the inner cavity of the connecting plate 204. Multiple nozzles are evenly provided on the bottom of the first conveying pipe 202, the inner side of the middle section of the second conveying pipe 203, the top of the lower section, and the outer wall of the third conveying pipe 205.

[0038] After the feed is fed into the diversion component, the conveyed material enters the first conveying pipe 202 and the second conveying pipe 203 through the annular diversion cavity 206 and the diversion hole 207. Part of the material in the second conveying pipe 203 enters the third conveying pipe 205 through the connecting plate 204. The staggered distribution of the first conveying pipe 202, the second conveying pipe 203 and the third conveying pipe 205 in the horizontal and vertical directions, combined with the multi-point setting of the nozzles, achieves uniform coverage of the treatment agent in the sewage tank from top to bottom and from the center to the periphery. This avoids the problems of dead corners in the dosing and local overconcentration of the agent, and ensures rapid and uniform mixing of sewage and treatment agent, thereby significantly improving the stability and reliability of the treatment effect.

[0039] Example 3

[0040] The structure of this embodiment is basically the same as that of embodiment two, except that, as Figure 1 , 2 As shown, the inlet filtration mechanism 100 includes a main ring plate 101 and a water-blocking ring plate 102 with an inclined sidewall fixed to the top of the main ring plate 101. An annular filter plate 103 is fixed to the upper inner side of the main ring plate 101. The central ring seat 201 of the diversion assembly is fixed to the center of the filter plate 103. Figure 6 As shown, an arc-shaped plate 104 is fixed along the radial direction at the position below each first conveying pipe 202 between the main ring plate 101 and the central ring seat 201. A fan-shaped guide plate 105 is provided above the two adjacent arc plates 104. The arc plates 104 and the guide plates 105 are evenly and spaced along the circumference. The inner and outer sides of the guide plates 105 are fixedly connected to the central ring seat 201 and the main ring plate 101, respectively, and the top surfaces are symmetrically inclined on both sides.

[0041] When wastewater is input, it is filtered by an annular filter plate 103 to intercept solid impurities. Then, with the cooperation of multiple guide plates 105, the wastewater falls into multiple arc-shaped plates 104. The nozzle of the first delivery pipe 202 sprays the treatment agent precisely into the arc-shaped plate 104. This allows the wastewater temporarily remaining on the arc-shaped plate 104 to undergo intense spraying and mixing with the agent in the limited space of the arc-shaped plate 104 before entering the main treatment area, thus achieving pretreatment. At the same time, the spraying force of the agent can also wash away any impurities or viscous liquids that may be deposited on the arc plate 104, which not only prevents solid particles from adhering and caking on the arc plate 104, but also ensures that the sewage can flow smoothly into the next treatment stage, thus realizing the dual functions of material conveying and plate self-cleaning.

[0042] Example 4

[0043] The structure of this embodiment is basically the same as that of Embodiment 1, except that, as Figure 8 , 9 As shown, the rotating assembly 300 includes a fixed cylinder 302 installed at the center of the diversion assembly. Connecting ears are symmetrically fixed on both sides of the top of the fixed cylinder 302. The top of the central ring seat 201 is provided with two mounting grooves. The fixed cylinder 302 is located inside the central ring seat 201, and the connecting ears are located in the mounting grooves and are fixedly connected to it by bolts. A vertical rotating cylinder 301 is rotatably connected to the inner side of the fixed cylinder 302. A transmission gear ring 303 is fixed on the upper part of the outer side wall of the rotating cylinder 301. A drive gear 304 is meshed on one side of the transmission gear ring 303. The drive gear 304 is connected to a motor. The motor is fixed on the top of the central ring seat 201 of the diversion assembly and is offset from the position of the conveying inlet pipe 209. Multiple horizontal first support cylinders 305 are uniformly fixed on the lower part of the outer side wall of the rotating cylinder 301 along the circumferential direction, and are correspondingly connected to the stirring and mixing assembly 500 through the first support cylinders 305. A vertical second support cylinder 306 is fixed at the center of the bottom end of the rotating cylinder 301, and is correspondingly connected to the self-rotating drive structure through the second support cylinder 306.

[0044] When it is necessary to move the feeding and dispersing assembly 400 and the mixing and stirring assembly 500, the rotating cylinder 301 is driven by the motor and the drive gear 304 and the transmission gear ring 303 to rotate the structure on it in the circumferential direction so as to carry out the corresponding feeding and mixing and stirring processes.

[0045] like Figure 10 As shown, the feeding and dispersing assembly 400 includes a vertical feeding cylinder 402 fixedly installed at the center of the rotating cylinder 301. A feeding hopper 401 is fixed to the top of the feeding cylinder 402, and multiple sets of impact blocks 403 are uniformly fixed along the vertical direction on the upper inner section. Each set includes multiple inclined impact blocks 403 evenly arranged along the circumference. A distributing circular seat 404 is fixed to the bottom of the feeding cylinder 402. Figure 4 As shown, the bottom surface of the inner cavity of the material distribution round seat 404 is uniformly provided with multiple inclined surfaces along the circumference, and the height gradually decreases from the center to the side. The bottom end of the material distribution round seat 404 is fixed with a material distribution pipe 405 corresponding to the lowest position of each inclined surface, and the outer section of the material distribution pipe 405 is set horizontally and connected to the stirring and mixing component 500.

[0046] When conveying solid particles and other agents, they enter through the feed hopper 401. During rotation, larger clumps of the agent fall into the impact block 403 under the action of gravity and rotation. The impact disperses the clumps, preventing large pieces of agent from directly clogging the downstream pipeline. The agent then falls into the distribution round seat 404, and from there enters the mixing and stirring components 500 at various locations through the distribution pipe 405 for further processing.

[0047] Among them, such as Figure 10 As shown, the top surface of the impact block 403 is inclined inward and downward, and the overall structure is set downward along the spiral direction with 0.6 to 0.8 spiral turns. The top surface is evenly distributed with pointed protrusions. During the rotation of the feeding dispersion component 400, the larger part of the falling solid material impacts the surface of the impact block 403 under the dual action of gravity and rotation, thus dispersing it and reducing the caking of the agent. The agent also contacts the pointed protrusions on the impact block 403, improving the dispersion effect.

[0048] like Figure 11As shown, the mixing and stirring assembly 500 includes a dispersing cylinder 501 rotatably connected to the first support cylinder 305. Multiple stirring plates 502 are uniformly fixed along the circumferential direction on the outer side of the dispersing cylinder 501, and dispersing holes are evenly distributed on the circumferential sidewall of the dispersing cylinder 501 at positions corresponding to adjacent stirring plates 502. The inner end of the dispersing cylinder 501 passes through the first support cylinder 305, extends into the rotating cylinder 301, and is connected to the self-driving structure.

[0049] The agent, after passing through the feeding and dispersing component 400, enters the dispersing cylinder 501 through the distributing pipe 405 under the action of rotation and centrifugation. The dispersing cylinder 501 revolves in the circumferential direction with the rotating cylinder 301, and at the same time, it achieves its own high-speed rotation through the self-transmission drive structure, so that the stirring plate 502 fixed on the outside of the dispersing cylinder 501 is stirred in the sewage. The agent is confined inside the dispersion cylinder 501, preventing solid agents from being directly discharged and settling to the bottom of the tank to form a hardened layer. The agent gradually dissolves and diffuses outward through the dispersion holes, fully mixing with the sewage and improving the sewage treatment effect.

[0050] The mixing and stirring assembly 500 of the present invention can also be used as a conventional stirring structure to mix wastewater and liquid agents or other substances without inputting solid agents.

[0051] like Figure 4 As shown, the self-rotating drive structure includes a first bevel gear 208 located at the bottom of the inner cavity of the rotating cylinder 301 and rotatably connected to the second support cylinder 306. The center of the first bevel gear 208 is fixedly connected to the multi-position conveying assembly. That is, the top end of the third conveying pipe 205 passes through the second support cylinder 306 and is fixedly connected to the first bevel gear 208. The inner ends of the multiple dispersing cylinders 501 are fixed with second bevel gears 503, and the multiple second bevel gears 503 mesh with the first bevel gear 208.

[0052] When the rotating cylinder 301 drives multiple dispersing cylinders 501 to rotate in the circumferential direction, multiple second bevel gears 503 rotate relative to the first bevel gear 208 in the circumferential direction, thereby driving the second bevel gears 503 to rotate the dispersing cylinders 501 through the first bevel gear 208, thus realizing the movement of the stirring plate 502.

[0053] Example 5

[0054] The structure of this embodiment is basically the same as that of embodiment four, except that, as Figure 12As shown, a connecting frame 504 that tilts downwards and outwards is fixed on the outer wall of the rotating cylinder 301 at the position corresponding to each stirring and mixing component 500. A horizontal limiting shaft 505 is fixed inside the outer end of the connecting frame 504. The center of the outer end of the dispersing cylinder 501 is rotatably connected to the limiting shaft 505. The connecting frame 504 and the limiting shaft 505 provide limiting support for the outer end of the dispersing cylinder 501, avoiding problems such as suspension of the outer end of the dispersing cylinder 501 and instability caused by rotation.
