Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology and relates to a structure for removing metal flocculent matter. Background Technology

[0002] In the treatment of heavy metal wastewater, metal flocs are generated through chemical precipitation, co-precipitation, or flocculation. Specifically, chemical agents (such as sodium hydroxide, lime, etc.) are added to the wastewater to convert heavy metal ions in the water into insoluble metal hydroxides or carbonate precipitates; or iron salts or other metal salts are added as co-precipitants to promote the precipitation of heavy metal ions with these substances, forming larger flocs; or flocculants are used to enhance the aggregation between fine particles, causing them to form even larger flocs. The formation of metal flocs helps to separate heavy metal ions from wastewater, reducing the heavy metal content in the wastewater.

[0003] Magnetic roller processing utilizes the attraction of a magnetic field to magnetic materials to achieve efficient solid-liquid separation. If the metal flocculent material adsorbed on the surface of the magnetic roller is not scraped off in time during use, the adsorption capacity of the magnetic roller will be reduced, thus reducing the separation effect. The metal flocculent material that is not effectively separated will be discharged with the water flow, requiring secondary processing, which increases the workload and resource consumption of subsequent processing steps. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a metal flocculent removal structure that can promptly scrape away metal flocculents adsorbed on the surface of the magnetic roller during use, ensuring the magnetic roller's adsorption capacity and improving the separation effect.

[0006] The container is equipped with a stirring mechanism installed on the side wall via a drive mechanism. The stirring mechanism is located inside the container and includes a transmission rod with multiple blades arranged circumferentially for stirring. The stirring mechanism is connected to a support rod via a reducer, and a magnetic roller is sleeved on the support rod. A scraper is provided between the magnetic roller and the collection box.

[0007] Furthermore, the drive mechanism includes a motor, and fixing plates are disposed on both sides of the motor, the fixing plates being fixedly connected to the side walls of the housing;

[0008] The output shaft of the motor is connected to the side wall of the housing through a sealed bearing, and the output shaft of the motor extends into the housing and is fixedly connected to the transmission rod coaxially.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] A structure for removing metal flocculent material, such as Figure 1-2 As shown, the device includes a housing 1, with multiple support legs 11 symmetrically arranged at the bottom of the housing 1. A water supply pipe 12 and a liquid distribution pipe 13, connected to the interior of the housing 1, are respectively provided on the top side wall of the housing 1. A water outlet pipe 14 and a sewage discharge pipe 15, connected to the interior of the housing 1, are respectively provided at the bottom of the housing 1. A collection box 2 is fixedly installed on the side wall of the housing 1. A discharge pipe 21 is connected to the bottom of the collection box 2, and the end of the discharge pipe 21 furthest from the collection box 2 is connected to the sewage discharge pipe 15. Heavy metal wastewater to be treated is transported into the housing 1 through the water supply pipe 12, and reagents (coagulant, coagulant aid, and magnetic powder) are added into the housing 1 through the liquid distribution pipe 13. After thorough mixing and reaction, metal flocculents are formed.

[0027] Furthermore, the addition of magnetic powder will form high-density composite magnetic flocs, which can greatly enhance the flocculation effect. At the same time, the magnetic powder and pollutants will agglomerate into large flocs, and the specific gravity will increase significantly, which will also facilitate the sedimentation of destabilized colloids, thereby achieving the purpose of enhancing the removal effect and accelerating sedimentation. The settled flocs can be centrifuged to separate the magnetic powder, and then recycled and reused in the system to reduce the treatment cost.

[0028] like Figure 3As shown, the mixing mechanism is installed in the box 1 through the driving mechanism 3 set on the side wall. The driving mechanism 3 includes a motor 31. Fixing plates 32 are arranged on both sides of the motor 31 and are fixedly connected to the side wall of the box 1. The output shaft of the motor 31 is connected to the side wall of the box 1 through the sealed bearing 33. The output shaft of the motor 31 extends into the box 1 and is fixedly connected to the transmission rod 4 coaxially.

[0029] like Figure 4 As shown, the stirring mechanism is located inside the housing 1. The stirring mechanism includes a transmission rod 4, with multiple blades 41 arranged circumferentially for stirring. The stirring mechanism is connected to a support rod 61 via a reducer 5. Two brackets 51 are fixedly connected to the side wall of the reducer 5, and the two brackets 51 are symmetrically arranged. The ends of the two brackets 51 away from the reducer 5 are respectively fixedly connected to the inner wall of the housing 1. The input end of the reducer 5 is connected to the end of the transmission rod 4, and the output end of the reducer 5 is connected to the end of the support rod 61. The end of the support rod 61 away from the reducer 5 is rotatably connected to the inner wall of the housing 1. It should be noted that after the motor 31 is started, the output shaft of the motor 31 will drive the transmission rod 4 to rotate synchronously. The multiple blades 41 arranged circumferentially on the transmission rod 4 rotate, thereby promoting the flow of liquid inside the housing 1, so that the sewage and flocculant are fully mixed, which facilitates the formation of metallic flocs. Furthermore, under the drive of the reducer 5, the magnetic roller 6 rotates at a low speed, so that the magnetic powder carrying the flocculents is adsorbed onto the magnetic roller 6 for collection.

[0030] like Figure 3-5 As shown, a magnetic roller 6 is sleeved on the support rod 61, and a scraper 7 is provided between the magnetic roller 6 and the collection box 2. The box body 1 is connected to the inside of the collection box 2 through a circulation groove 16 opened on the side wall, and the size of the circulation groove 16 corresponds to the position of the scraper 7. One end of the scraper 7 is in contact with the outer surface of the magnetic roller 6, and the other end of the scraper 7 extends into the collection box 2 through the circulation groove 16; Figure 2 As shown, the scraper 7 is fixedly connected to the bottom inner wall of the circulation tank 16, that is, it is fixedly installed relative to the box body 1. The magnetic roller 6 rotates in one direction, so that the composite magnetic flocs attached to the surface of the magnetic roller 6 are scraped off by the scraper 7 and fall onto the upper surface of the scraper 7 to clean the surface of the magnetic roller 6, so that the magnetic roller 6 can better adsorb metal flocs and improve the removal effect of impurities in sewage.

[0031] The blades 41 rotate, thus agitating the water flow inside the tank 1, accelerating the mixing of wastewater and flocculant, and speeding up the formation of flocs. The scraper 7 is tilted, guiding the scraped flocs to fall under gravity, improving the collection effect. The end of the scraper 7 away from the magnetic roller 6 is tilted downwards and extends into the collection tank 2 through the circulation trough 16, ensuring that the flocs fall into the collection tank 2. As the flocs accumulate in the collection tank 2, the wastewater inside the collection tank 2 can be squeezed out again from the circulation trough 16. In addition, by opening the valves on the drain pipe 15 and the discharge pipe 21 respectively, the flocculated material in the tank 1 can be discharged, facilitating the subsequent unified treatment of the composite flocculated material.

[0032] The various embodiments in this specification are described in a related manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
