A flocculation device for enhanced flocculation wastewater treatment

Abstract

This utility model discloses a flocculation device for enhanced flocculation wastewater treatment, including a treatment tank, a top cover, an outlet valve, and an injection valve. The treatment tank contains an additive component for uniformly adding flocculant into the wastewater. Inside the treatment tank, located next to the injection valve, is a primary screening component for filtering larger impurities. Two sets of stirring components are located on the sides of the treatment tank to fully mix the wastewater and flocculant. As the rotating column rotates, the uppermost stirring blades initially mix and disperse the wastewater and flocculant, while the middle stirring turbine blades generate strong vortices to enhance the mixing effect. The lowermost anchor blades fully stir the wastewater at the bottom of the treatment tank, preventing particulate impurities from accumulating and failing to mix fully with the flocculant. Simultaneously, two sets of inclined dosing pipes ensure that the flocculant is evenly dispersed within the wastewater, thereby improving the mixing effect between the flocculant and wastewater and ultimately enhancing the wastewater treatment efficiency.

Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a flocculation device for enhanced flocculation wastewater treatment. Background Technology

[0002] Flocculation refers to the phenomenon or operation of causing suspended particles in water or liquid to aggregate and become larger, or to form flocs, thereby accelerating particle sedimentation and achieving solid-liquid separation. In the field of wastewater treatment, flocculation is a key step, as it can cause tiny particles and colloids in wastewater to aggregate into larger flocs, facilitating subsequent sedimentation, filtration, and other operations. However, traditional flocculation devices have many shortcomings in practical applications, such as poor mixing effect between flocculant and wastewater. They are usually just simple stirring, which makes it difficult to disperse the flocculant quickly and evenly in the wastewater, resulting in insufficient flocculation reaction and affecting the treatment effect.

[0003] In the prior art, the patent announcement number CN206735881U discloses a flocculation device for papermaking wastewater treatment, including a flocculation tank. The flocculation tank includes a filter frame and a flocculant mixing mechanism disposed inside the filter frame. The filter frame is connected to an inlet pipe, and the flocculant mixing mechanism is connected to a flocculant addition pipe. The flocculant mixing mechanism is provided with a plurality of small holes, and the flocculant mixing mechanism is connected to a rotary motor disposed at the top of the flocculation tank.

[0004] The aforementioned patent has the drawback of poor mixing between the flocculant and the wastewater, failing to stir the granular impurities settled at the bottom. Consequently, the granules cannot be fully mixed with the flocculant, making it difficult for the flocculant to disperse quickly and evenly in the wastewater. This results in insufficient flocculation reaction and affects the treatment effect. Therefore, we need to propose a flocculation device for enhanced flocculation wastewater treatment.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all 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] This utility model provides: a flocculation device for enhanced flocculation wastewater treatment, such as... Figure 1-4As shown, it includes a treatment tank 1, a top cover 2, an outlet valve 7, and an injection valve 17. Wastewater enters the treatment tank 1 through the injection valve 17, is treated by the treatment tank 1, and is then discharged through the outlet valve 7. The water injection and discharge are controlled by the outlet valve 7 and the injection valve 17. The top cover 2 is bolted to the upper surface of the treatment tank 1. When it is necessary to clean the internal structure of the treatment tank 1, the top cover 2 can be opened.

[0026] Preferably, the treatment tank 1 has two sets of stirring components on its side for fully mixing the wastewater and flocculant. Each stirring component includes a rotating column 8, stirring blades 9, stirring turbine blades 16, anchor blades 20, and a drive module for rotating the rotating column 8. Two sets of each of the rotating column 8, stirring blades 9, stirring turbine blades 16, and anchor blades 20 are provided, and each is sleeved onto the corresponding outer arc surface of the rotating column 8. A sludge collection hopper 21 is sealed to the lower surface of the treatment tank 1, and several sets of [unspecified components] are fixedly installed inside the treatment tank 1 and above the sludge collection hopper 21. The capture plate 19 and the stirring turbine blade 16 are located between the stirring blade 9 and the anchor blade 20, with the anchor blade 20 located at the bottom of the rotating column 8. The lower surface of the anchor blade 20 is in contact with the upper surface of the capture plate 19. The surface of the capture plate 19 has been specially treated to have hydrophilicity and a certain degree of adsorption, which can effectively capture and aggregate flocs. The two sets of rotating columns 8 are driven to rotate by the drive module. The uppermost stirring blade 9 plays a role in initially mixing and dispersing the sewage and flocculant. The middle layer of stirring turbine blade 16 generates a strong vortex to enhance the mixing effect. The bottommost anchor blade 20 fully stirs the sewage at the bottom of the treatment tank 1.

[0027] Furthermore, the drive module includes a motor 4, a drive gear 13, a toothed belt 14, and a driven gear 15. The motor 4 is mounted on the upper surface of the top cover 2 via a support frame. The drive gear 13 and the driven gear 15 are rotatably mounted on the upper surface of the top cover 2. The output end of the motor 4 is fixedly connected to the drive gear 13 via a connecting column, and the toothed belt 14 is meshed with the outer arc surface of the drive gear 13 and the driven gear 15. By starting the motor 4, the drive gear 13 is driven to rotate. The drive gear 13 drives the driven gear 15 to rotate via the toothed belt 14, thereby driving the driven gear 15 to rotate. In turn, the drive gear 13 and the driven gear 15 drive the two sets of rotating columns 8 to rotate, thereby fully mixing the sewage and flocculant inside the treatment tank 1. The motor 4 can be a YE3 series model, and the motor can be controlled by a programmable logic controller such as the Siemens S7-1200 series.

[0028] Furthermore, the treatment tank 1 is equipped with an additive assembly for uniformly adding flocculant into the wastewater. This assembly includes an additive tank 3, connecting pipes 6, and dosing pipes 12. The additive tank 3 is mounted on the upper surface of the top cover 2 via another support frame. Two sets of connecting pipes 6 and dosing pipes 12 are provided, symmetrically arranged on both sides of the additive tank 3. Each set of dosing pipes 12 is sealed to its corresponding connecting pipe 6. Both sets of dosing pipes 12 are located inside the treatment tank 1, inclined within the tank. Each set of dosing pipes 12 has several dosing holes on its outer arc surface. Neither set of dosing pipes 12 contacts the stirring blades 9, the stirring turbine blades 16, or the anchor blades 20, thus ensuring stability during rotation. The additive tank 3 stores flocculant and a pump body, injecting flocculant into the treatment tank 1 through the connecting pipes 6 and dosing pipes 12. The two sets of dosing pipes 12 are arranged as follows: Figure 3 The inclined setting ensures that the two sets of liquid injection pipes 12 can inject flocculant into multiple locations inside the treatment tank 1.

[0029] It is worth noting that a primary screening assembly for filtering larger impurities is provided inside the treatment tank 1 and on the side of the water injection valve 17. The primary screening assembly includes a connecting cover 5, a primary screening box 11, and an inclined plate 18. The primary screening box 11 is slidably disposed inside the treatment tank 1, the connecting cover 5 is sealed to the surface of the primary screening box 11, and the inclined plate 18 is fixedly disposed inside the primary screening box 11 and contacts the inner wall of the treatment tank 1. The outer arc surface of the primary screening box 11 has several sets of primary screening holes. The primary screening box 11 is set to perform preliminary filtration of the sewage injected by the water injection valve 17, filtering larger impurities into the primary screening box 11. When there are too many impurities inside the primary screening box 11, the connecting cover 5 is pulled to remove the primary screening box 11 from the treatment tank 1. The inclined plate 18 is in contact with the treatment tank 1 to prevent impurities from leaking back into the treatment tank 1 when the primary screening box 11 is removed, thereby preventing excessive impurities inside the treatment tank 1 from getting tangled on the outside of the stirring structure and affecting the sewage treatment effect.

[0030] Specifically, the primary screening box 11 is symmetrically provided with snap-fit ​​blocks 23 on both sides, and the processing box 1 has a snap-fit ​​groove 10 corresponding to the snap-fit ​​blocks 23 on the inner side. The connecting cover 5 is provided with a sealing strip 22 on the side, and the top cover 2 has a sealing groove corresponding to the sealing strip 22 on the inner side. The snap-fit ​​blocks 23 are convex blocks and are snapped into the snap-fit ​​groove 10 to ensure the stability of the primary screening box 11 during the pulling process. When the primary screening box 11 is inserted back into the processing box 1, the sealing strip 22 will be snapped into the sealing groove to prevent sewage from seeping out through the connecting cover 5.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
