Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a flocculant stirring device for sewage treatment. Background Art

[0002] Flocculants are mainly applied to the fields of water supply and sewage treatment. Flocculants can be generally divided into two categories: inorganic flocculants and organic flocculants according to their chemical compositions. Among them, inorganic flocculants include inorganic coagulants and inorganic polymer flocculants; organic flocculants include synthetic organic polymer flocculants, natural organic polymer flocculants and microbial flocculants.

[0003] When the existing flocculant for sewage treatment is poured into the sewage to flocculate impurities in the sewage, the flocculant is usually directly poured into the sewage. However, when the flocculant is directly poured, the flocculant will start to diffuse above the sewage, but the diffusion speed of the flocculant is slow, resulting in a low content of flocculant at the lower end of the sewage, affecting the overall flocculation effect on the sewage. In actual use, a stirring plate is often used to stir the sewage to improve the diffusion speed of the flocculant. However, the centrifugal force generated during stirring may cause the flocculation product to adhere to the side wall of the barrel, resulting in the retention of the flocculation product in the barrel and being inconvenient to clean. Summary of the Utility Model

In actual use, a stirring plate is often used to stir the sewage to improve the diffusion speed of the flocculant. However, the centrifugal force generated during stirring may cause the flocculation product to adhere to the side wall of the barrel, resulting in the retention of the flocculation product in the barrel and being inconvenient to clean.

[0010] As a preferred embodiment, a scraper is fixedly connected to the side end of the L-shaped connecting frame, and the scraper abuts against the inner wall of the stirring barrel to prevent flocculation products from remaining on the inner wall of the stirring barrel.

[0011] As a preferred embodiment, the flocculant input pipe is fixedly connected to a flange at one end away from the control box, and the lower end of the stirring barrel is fixedly connected to a water tap, so that the flocculant pipeline can be easily connected via the flange.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all 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 efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5The utility model provides a technical solution: a flocculant stirring device for sewage treatment, comprising a stirring barrel 1, a control box 2 is fixedly connected to the top of the stirring barrel 1, a flocculant input pipe 3 is fixedly connected to the top of the control box 2, a stirring shaft 7 is rotatably connected in the stirring barrel 1, the top of the stirring shaft 7 penetrates to the flocculant input pipe 3, a cavity 20 is opened in the stirring shaft 7, a plurality of through holes 11 connected to the cavity 20 are opened on the outer wall of the stirring shaft 7, a rotating rod 13 is rotatably connected in the through hole 11, and a stopper 10 is rotatably connected on the rotating rod 13. By storing flocculant in the stirring shaft 7 and arranging a plurality of through holes 11 distributed in layers to cooperate with the stopper 10, when the stirring shaft 7 rotates, the plurality of stoppers 10 can be simultaneously prevented from blocking the through holes 11 by centrifugal force, so that the flocculant in the cavity 20 can be evenly dispersed in the sewage through the through holes 11, thereby improving the uniformity of the flocculant in the sewage and making the flocculant content in each part of the sewage evenly distributed.

[0025] like Figures 1-5 As shown, a magnet sheet 12 is fixedly connected in the through hole 11, and the block 10 is made of ferromagnetic material. When there is no need to add flocculant, the block 10 is tightly attached to the magnet sheet 12 through the action of the magnet sheet 12 to achieve the blocking function of the through hole 11 and prevent the flocculant in the cavity 20 from leaking.

[0026] like Figures 1-5 As shown, a plurality of first stirring blades 18 are fixedly connected to the outer circumference of the stirring shaft 7, a sleeve 14 is rotatably connected to the top of the stirring barrel 1, the sleeve 14 is sleeved on the outer circumference of the stirring shaft 7, four L-shaped connecting frames 8 are fixedly connected to the outer circumference of the sleeve 14, and a plurality of second stirring blades 19 are fixedly connected to the side wall of the vertical end of the L-shaped connecting frame 8. By arranging the first stirring blades 18 and the second stirring blades 19, it is convenient to drive the sewage in the stirring barrel 1 to generate vortexes, thereby improving the flocculation reaction efficiency of the flocculant in the sewage.

[0027] like Figures 1-5 As shown, a driving bevel gear 17 is rotatably connected in the control box 2, a second driven bevel gear 16 is fixedly connected to the top of the stirring shaft 7, and a first driven bevel gear 15 is fixedly connected to the top of the sleeve 14. The driving bevel gear 17 is meshed and transmission-connected with the first driven bevel gear 15 and the second driven bevel gear 16. The driving bevel gear 17 cooperates with the second driven bevel gear 16 and the first driven bevel gear 15, so that the first driven bevel gear 15 and the second driven bevel gear 16 output two different rotation directions.

[0028] like Figures 1-5As shown in the figure, a mounting base 5 is fixedly connected to the top end of the stirring barrel 1. A driving motor 6 is embedded and installed in the mounting base 5. The output end of the driving motor 6 is fixedly connected to the driving bevel gear 17. The driving motor 6 serves as the power source of the device. By setting the driving motor 6, the driving bevel gear 17 can be driven, so as to drive the first driven bevel gear 15 and the second driven bevel gear 16 to rotate, and drive the L-shaped connecting frame 8 and the stirring shaft 7 to rotate.

[0029] As Figures 1-5 shown, a scraping plate 9 is fixedly connected to the side end of the L-shaped connecting frame 8. The scraping plate 9 abuts against the inner wall of the stirring barrel 1. When the L-shaped connecting frame 8 rotates, the sediment adhering to the inner wall of the stirring barrel 1 can be scraped off, preventing the residual flocculation products in the stirring barrel 1 after the sewage is discharged from the stirring barrel 1.

[0030] As Figures 1-5 shown, a flange 4 is fixedly connected to the end of the flocculant input pipe 3 far away from the control box 2. A water outlet tap 21 is fixedly connected to the lower end of the stirring barrel 1. The flocculant input pipe 3 is flange-connected through the flange 4, which is convenient for installing the flocculant pipeline.

[0031] As Figures 1-5 shown, three legs 22 are fixedly connected to the bottom end of the stirring barrel 1. The bottom ends of the multiple legs 22 are all fixedly connected with foot supports 23. The friction between the legs 22 and the ground is increased through the foot supports 23, and the support stability of the legs 22 is improved.

[0032] Working principle: When treating sewage, the flocculant pipeline is flange-connected through the flange 4, so that the flocculant enters the storage cavity 20 inside the stirring shaft 7 through the flocculant input pipe 3. When the flocculant needs to be added, the driving motor 6 is started. The driving motor 6 drives the driving bevel gear 17 to rotate. The driving bevel gear 17 simultaneously drives the first driven bevel gear 15 and the second driven bevel gear 16 to rotate. When the first driven bevel gear 15 rotates, it drives the stirring shaft 7 to rotate. During the rotation of the stirring shaft 7, the stopper 10 rotates around the rotating rod 13 under the action of centrifugal force, so that the stopper 10 no longer blocks the through holes 11, and the flocculant in the cavity 20 is simultaneously released from the plurality of through holes 11 into each layer of the sewage, so that the flocculant is evenly distributed in the sewage, improving the flocculation effect. And the first stirring blade 18 is driven by the rotation of the stirring shaft 7 to stir the sewage. When the second driven bevel gear 16 rotates, it drives the L-shaped connecting frame 8 to rotate. When the L-shaped connecting frame 8 rotates, the coagulated matter attached to the inner wall of the stirring barrel 1 is scraped off by the scraping plate 9 to prevent the coagulated matter from adhering to the inner wall of the stirring barrel 1. When the L-shaped connecting frame 8 rotates, the second stirring blade 19 makes the sewage rotate, and the rotation direction is opposite to the rotation direction of the sewage driven by the stirring shaft 7 when rotating, so that the sewage rotates between the first stirring blade 18 and the second stirring blade 19. This relative motion will increase the velocity difference and shear force of the sewage, resulting in the formation of stronger eddies. The enhancement of the eddies can improve the mixing effect of the flocculant in the sewage and improve the flocculation efficiency.

[0033] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
