Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically a new type of phosphorus removal flotation machine. Background Technology

[0002] In recent years, environmental protection has become a global focus, especially in wastewater treatment. Removing phosphorus from wastewater is a crucial task in this field. Currently, many small towns use a "rotary drum screen + conditioning tank + screw press + dissolved air flotation unit + two-stage A / O + MBR" process for waste treatment at their garbage transfer stations. However, with the rapid increase in the amount of garbage, the processing capacity of these transfer stations has risen sharply. This has led to a continuous increase in the load on the two-stage A / O system, making it difficult to control the sludge properties in the two-stage A / O system. Consequently, the total phosphorus content in the effluent from the transfer station often fails to meet standards.

[0003] In existing technologies, traditional air flotation machines have a short mixing time during phosphorus removal, which usually cannot guarantee sufficient contact between the reagent and the wastewater. The reagent and the feed are not mixed sufficiently, resulting in poor reaction effect, affecting phosphorus removal efficiency and reducing the phosphorus removal effect.

[0004] Therefore, this utility model provides a novel phosphorus removal flotation machine. Utility Model Content

[0005] To address the shortcomings of existing technologies and solve the problem that traditional air flotation machines have short mixing times during phosphorus removal, which often fail to ensure sufficient contact between the reagent and the wastewater, and insufficient mixing between the reagent and the feed, resulting in poor reaction effects, reduced phosphorus removal efficiency, and decreased phosphorus removal effectiveness.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A novel phosphorus removal flotation machine of this utility model includes a flotation machine body. A mixing mechanism is provided on the flotation machine body. The mixing mechanism includes: a mixing component, comprising a support plate fixedly connected between opposite side walls of the flotation machine body; a rotating rod rotatably connected to the support plate through a pair of first rotating holes; a set of stirring blades fixedly connected to the rotating rod; a sliding rod slidably connected to the support plate through sliding holes; an elliptical block slidably connected to the sliding rod; and a power component provided on the support plate for driving the pair of rotating rods to rotate and the sliding rod to slide; and a drug delivery component, provided on the side wall of the flotation machine body for delivering the drug.

[0007] Preferably, the power assembly includes a motor fixed to the top of the support plate via an L-shaped rod, the output end of the motor being driven by a rotating rod, and a pair of sprockets fixed to each of the rotating rods, the pair of sprockets being connected by a chain drive.

[0008] Preferably, a rectangular block is fixed to the top of the sliding rod, the rectangular block is connected to the support plate by a spring, a circular block is fixed to the rotating rod, the circular block has a wave groove, and a circular rod is fixed to the side wall of the rectangular block, with one end of the circular rod located in the wave groove.

[0009] Preferably, the drug delivery assembly includes a drug tank fixed to the side wall of the air flotation machine body by a pair of L-shaped frames. The drug tank is connected to the air flotation machine body through a connecting pipe. A partition is fixed to the inner circular wall of the drug tank, and a first rectangular groove is provided on the partition.

[0010] Preferably, a linkage rod is rotatably connected to one side of the medicine barrel through a second rotating hole, and one end of the linkage rod extends into the medicine barrel. A rotating plate is fixedly connected to the end of the rotating rod located inside the medicine barrel. A second rectangular groove is provided on the rotating plate. A scraper is fixedly connected to the rotating rod through a set of fixing rods.

[0011] Preferably, a first helical gear is fixedly connected to one end of the linkage rod, and a second helical gear is fixedly connected to the top of the rotating rod, with the first helical gear and the second helical gear meshing together.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The novel phosphorus removal flotation machine of this utility model, through a set power component, can drive a pair of rotating rods to rotate, thereby stirring through the stirring blades, improving stirring efficiency, and simultaneously driving the sliding rod to vibrate up and down, which can vibrate the sewage through the elliptical block. Stirring can promote the full mixing of flocculant and phosphorus in sewage, forming larger flocs. At the same time, vibration can further break the agglomeration of flocs, making them more evenly distributed in the water, improving the flocculation effect. This solves the problem in the prior art where the stirring time is too short, the mixing of the agent and the feed is not sufficient, resulting in poor reaction effect, affecting the phosphorus removal efficiency, and reducing the phosphorus removal effect.

[0014] 2. The novel phosphorus removal flotation machine of this utility model, by rotating a pair of rotating rods, enables the second helical gear on the rotating rods to drive the first helical gear to rotate, which in turn drives the linkage rod to rotate, thereby driving the scraper and the rotating plate to rotate. The rotation of the rotating plate allows the second rectangular trough to intermittently communicate with the first rectangular trough, thereby achieving the purpose of intermittent delivery of the reagent. The precise addition of the reagent can avoid equipment blockage caused by excessive reagent and extend the service life of the equipment. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5 As shown in the embodiment of this utility model, a novel phosphorus removal flotation machine includes a flotation machine body 1. A mixing mechanism is provided on the flotation machine body 1, comprising: a mixing component including a support plate 2 fixedly connected between opposite side walls of the flotation machine body 1; a rotating rod 3 rotatably connected to the support plate 2 through a pair of first rotating holes; a set of stirring blades fixedly connected to the rotating rod 3; a sliding rod 4 slidably connected to the support plate 2 through sliding holes; an elliptical block 5 slidably connected to the sliding rod 4; and a power component on the support plate 2 for driving the pair of rotating rods 3 to rotate and the sliding rod 4 to slide; and a drug delivery component, provided on the side wall of the flotation machine body 1 for... During operation, the power unit drives a pair of rotating rods 3 to rotate, thereby agitating the wastewater through the stirring blades and improving the agitation efficiency. Simultaneously, it drives the sliding rod 4 to vibrate up and down, which in turn vibrates the wastewater through the elliptical block 5. This agitation promotes thorough mixing of the flocculant and phosphates in the wastewater, forming larger flocs. At the same time, the vibration further breaks down the agglomeration of the flocs, making them more evenly distributed in the water and improving the flocculation effect. This solves the problem in existing technologies where the agitation time is too short, the mixing of the agent and the feed is insufficient, resulting in poor reaction effect, affecting the phosphorus removal efficiency, and reducing the phosphorus removal effect.

[0024] The power assembly includes a motor 6 fixed to the top of the support plate 2 via an L-shaped rod. The output end of the motor 6 is connected to the rotating rod 3 for driving. A pair of rotating rods 3 are each fixed with a sprocket 7, which are connected by a chain 8. A rectangular block 9 is fixed to the top of the sliding rod 4, which is connected to the support plate 2 via a spring 10. A circular block 11 is fixed to the rotating rod 3, and a wave groove 12 is provided on the circular block 11. A circular rod 13 is fixed to the side wall of the rectangular block 9, with one end of the circular rod 13 located in the wave groove 12. During operation, the pair of rotating rods 3 are linked by the pair of sprockets 7 and the chain 8, and because one end of the circular rod 13 is located in the wave groove 12, they can move under the drive of the same power source, which can improve the mixing effect while reducing the operating cost.

[0025] The drug delivery assembly includes a drug tank 14 fixed to the side wall of the flotation machine body 1 via a pair of L-shaped brackets. The drug tank 14 is connected to the flotation machine body 1 via a connecting pipe. A partition 15 is fixed to the inner circular wall of the drug tank 14, and a first rectangular groove 16 is formed on the partition 15. A linkage rod 17 is rotatably connected to one side of the drug tank 14 via a second rotating hole, and one end of the linkage rod 17 extends into the drug tank 14. A rotating plate 18 is fixed to one end of a rotating rod 3 located inside the drug tank 14. A second rectangular groove 19 is formed on the rotating plate 18. A scraper 20 is fixed to the rotating rod 3 via a set of fixed rods. A first helical gear 21 is fixed to one end of the linkage rod 17. A second helical gear 22 is fixedly connected to the top of the rod 3. The first helical gear 21 is meshed with the second helical gear 22. During operation, the rotation of a pair of rotating rods 3 causes the second helical gear 22 on the rotating rod 3 to drive the first helical gear 21 to rotate, which in turn drives the linkage rod 17 to rotate. This, in turn, drives the scraper 20 and the rotating plate 18 to rotate. The rotation of the rotating plate 18 allows the second rectangular groove 19 to intermittently communicate with the first rectangular groove 16, thereby achieving the purpose of intermittent delivery of the agent. Precise addition of the agent can avoid equipment blockage caused by excessive agent and extend the service life of the equipment.

[0026] Working Principle: A power unit drives a pair of rotating rods 3 to rotate, thereby agitating the wastewater through the stirring blades and improving agitation efficiency. Simultaneously, it drives the sliding rods 4 to vibrate up and down, which in turn vibrates the wastewater through the elliptical blocks 5. This agitation promotes thorough mixing of the flocculant and phosphates in the wastewater, forming larger flocs. Furthermore, the vibration further breaks up floc aggregation, allowing for more even distribution in the water and improving flocculation. This addresses the shortcomings of existing technologies, such as short agitation time, insufficient mixing of the agent and feed, resulting in poor reaction effects and reduced phosphorus removal efficiency. A pair of sprockets 7 and a chain 8 further agitate the rotating rods 3. The system is linked together, and one end of the circular rod 13 is located inside the wave groove 12, so that they can move under the same power source. This can improve the mixing effect and reduce the operating cost. By rotating a pair of rotating rods 3, the second helical gear 22 on the rotating rod 3 drives the first helical gear 21 to rotate, which in turn drives the linkage rod 17 to rotate. This drives the scraper 20 and the rotating plate 18 to rotate. The rotation of the rotating plate 18 allows the second rectangular groove 19 to intermittently communicate with the first rectangular groove 16, thereby achieving the purpose of intermittent delivery of the agent. Precise addition of the agent can avoid equipment blockage caused by excessive agent and extend the service life of the equipment.
