Description

Technical Field

[0001] This utility model belongs to the technical field of wastewater treatment, specifically relating to a demineralized water preparation device with zero wastewater discharge. Background Technology

[0002] Demineralized water refers to the final product obtained after removing suspended solids, colloids, and inorganic cations and anions from water using various water treatment processes. Traditional demineralized water preparation devices, after adding ion exchange agents and catalysts, can only accelerate catalysis through stirring, a relatively simple method that affects the reaction rate.

[0003] CN 222729499 U discloses a demineralized water preparation device, including a stirring tank, a mixing component disposed on the stirring tank, a dosing pipe and a water injection pipe disposed on the curved surface of the stirring tank and respectively disposed in a direction away from the top of the stirring tank, and a water outlet pipe located at the bottom of the stirring tank; the mixing component includes a housing connected to an output shaft, a support frame disposed within the housing, an adjusting motor disposed on one side of the support frame, an adjusting screw disposed at the output end of the adjusting motor, an adjusting element disposed on the adjusting screw, and three stirring blades disposed on the adjusting element; this device can change the position of the stirring blades in real time, thereby avoiding the solution in the stirring tank from rotating in a certain shape for a long time, and can also change the stirring area of ​​the stirring blades, thereby improving the stirring efficiency. However, in this demineralized water preparation device, both the displacement agent and the catalyst are directly added to the stirring tank during the stirring process. In order for the displacement agent and the catalyst to fully dissolve, the displacement agent and the catalyst need to be mixed with the wastewater for a long time; otherwise, when the displacement agent and the catalyst settle at the bottom of the stirring tank, they are prone to direct contact with the heating layer on its inner wall, resulting in overheating.

[0016] Please see Figure 1 and Figure 2This utility model provides a technical solution: a wastewater demineralized water preparation device with zero discharge, including a stirring tank 1 and a settling tank 2.

The mounting base 8 is provided with a return water inlet 14 to introduce the secondary treated water after settling in the settling tank 2 into the mixing plate 5. The secondary treated water in the settling tank 2 is then introduced into the mixing plate 5 through the return water inlet 14. The treated water is returned to the mixing tray 5 for further mixing and stirring. The mixing tray 5 is equipped with a transmission component 7 that, driven by the active stirring pipe 4, mixes the displacement agent, catalyst, and secondary treated water injected through the displacement agent injection port 11 and catalyst injection port 12. The active stirring pipe 4 circulates the mixed reagent solution into the mixing tank 1 for stirring.

The active stirring pipe 4 is driven by the motor 3, and the driven stirring component 6 is linked with the active stirring pipe 4 through the transmission component 7 to achieve reverse stirring, thereby enhancing the stirring effect. The mixing tray 5 is not only used to mix reagents and secondary treated water, but also, through the transmission component 7 and the active stirring pipe 4, drives the driven stirring component 6 to stir in the opposite direction.

[0017] Please see Figure 2 and Figure 3 The active stirring pipe 4 includes an active pipe shaft 41. The upper end of the active pipe shaft 41 is fixed to the output end of the motor 3. The lower end of the active pipe shaft 41 is rotatably connected to a first bracket 42 fixed inside the mixing tank 1. Several radially arranged first stirring blades 43 are fixed outside the active pipe shaft 41. An active gear 44 is fixed at the height of the active pipe shaft 41 at the position of the mixing plate 5. A partition 45 is fixed inside the active pipe shaft 41. A return water inlet 14 is provided on the mounting base 8. Secondary treated water in the settling tank 2 is introduced into the inner cavity of the active pipe shaft 41. Through the obstruction of the partition 45, it enters the mixing plate 5 and mixes with the displacement agent and catalyst. A guide component is fixed inside the active pipe shaft 41 below the partition 45. The guide component includes a central rod 46. A spiral plate 47 is fixed between the central rod 46 and the cavity of the active pipe shaft 41. The guide component adopts the spiral plate 47 design, which can effectively guide the flow of the mixed liquid in the active pipe shaft 41 and enhance the mixing effect.

[0018] Furthermore, the active tube shaft 41 has a first guide hole 411 communicating with the mounting base 8, the active tube shaft 41 has a second guide hole 412 communicating with the inner cavity of the mixing tray 5 above the partition plate 45, the active tube shaft 41 has a third guide hole 413 communicating with the inner cavity of the mixing tray 5 below the partition plate 45, and the active tube shaft 41 has several evenly distributed fourth guide holes 414 below the mixing tray 5. The mixed liquid can be guided by the spiral plate 47 of the guide component and spirally descend along the active tube shaft 41, and enter the mixing tank through the fourth guide holes 414 at different heights.

A second bracket 62 is fixed to the lower end of the fixed rod 61. The second bracket 62 is rotatably connected to the active tube shaft 41. A scraper 63 that is attached to the inner wall of the mixing tank 1 is fixed to one side of the fixed rod 61. Several second stirring blades 64 that are radially arranged relative to the active tube shaft 41 are fixed to the other side of the fixed rod 61. The first stirring blades 43 and the second stirring blades 64 are arranged alternately up and down.

[0020] Please see Figure 2 and Figure 5 The transmission component 7 includes a driven tube shaft 71, which is rotatably connected to the mixing tank 1. Several third stirring blades 72 are radially fixed on the outer side of the lower end of the driven tube shaft 71. A driven gear 73 is fixed in the middle of the driven tube shaft 71. A toothed ring 51 is fixed on the inner wall of the mixing disc 5. The driven gear 73 meshes with the driving gear 44 and the toothed ring 51 respectively. Through the meshing of the driven gear 73 with the driving gear 44 and the toothed ring 51 in the transmission component 7, the driven stirring component 6 is rotated in the opposite direction, thereby enhancing the stirring effect. The upper end of the driven tube shaft 71 extends to the outside of the mixing tank 1 and is rotatably connected to a rotary joint 74, which is fixed on the mixing tank 1.

[0021] The working principle and usage process of this utility model: The raw water to be treated enters the mixing tank 1 through the raw water inlet 13 and is heated under stirring. After treatment, the secondary water is fed into the settling tank 2 through the bottom outlet and settling. Part of the secondary treated water in the settling tank 2 that still has temperature flows back to the inner cavity of the mounting base 8 through the return water inlet 14, enters the inner cavity of the active tube shaft 41 through the first guide hole 411, and then enters the mixing plate 5 through the second guide hole 412 under the obstruction of the partition plate 45. The displacement agent and the catalyst are respectively added into the mixing plate 5 through the displacement agent injection port 11 and the catalyst injection port 12. During the process of the motor 3 driving the active stirring tube 4 to stir in the stirring tank 1, the active gear 44 outside the active tube shaft 41 meshes with the driven gear 73, driving the driven tube shaft 71 to rotate. Then, the third stirring blade 72 outside the driven tube shaft 71 premixes the displacement agent and catalyst in the mixing plate 5 and the secondary treatment water with temperature. After mixing, the mixed liquid enters the cavity between the central rod 46 and the active tube shaft 41 through the third guide hole 413, and spirals down along the guide of the spiral plate 47. During the descent, it is passed into the stirring tank 1 through the fourth guide hole 414 at different height positions. During the pre-mixing process of the medicine and secondary treated water in the mixing disc 5 by the transmission component 7, the mixing disc 5 is driven to rotate by the meshing of the driven gear 73 and the gear ring 51, which in turn drives the scrapers 63 on both sides to rotate circumferentially around the active tube shaft 41. The scraper 63 on one side of the fixed rod 61 scrapes the inner wall of the mixing tank 1, and the second stirring blade 64 on the other side of the fixed rod 61 rotates in the opposite direction to the first stirring blade 43 to achieve stirring and mixing of the liquid inside the mixing tank 1.
