DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-3 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0025] Embodiment 1

[0026] Reference Figure 1-3A water treatment device based on a double-layer flow guide cover includes a pool body 1, a flow guide tube 3, two supporting baffles 5, a primary flow guide cover 6 and a secondary flow guide cover 7.

[0027] Specifically, the guide tube 3 is an L-shaped structure, and a water inlet 2 is provided at the lower end of the side wall of the pool body 1, and a water outlet 12 is provided at the upper end of the side wall of the pool body 1; one end of the guide tube 3 is connected to the water inlet 2, and the other end is vertically arranged inside the pool body 1 with the opening facing upward; in this embodiment, the other end of the guide tube 3 is vertically arranged in the center of the pool body 1. The guide tube 3 provides directional guidance for the water flow, so that the water flow can enter the pool body 1 in a more orderly manner, reducing the turbulence and energy loss of the water flow.

[0028] At the same time, one end of the two support baffles 5 is fixedly connected to the inner wall of the pool body 1, and the other end is fixedly connected to the outer wall of the vertical guide tube 3, and finally they are symmetrically arranged on both sides of the vertical guide tube 3 in a horizontal state, and the two support baffles 5 are at the same height inside the pool body 1. The two support baffles 5 are provided to provide space and support for installing the primary guide cover 6 and the secondary guide cover 7.

[0029] Reference Figure 2-3 The primary air guide cover 6 and the secondary air guide cover 7 are both cylindrical structures without a bottom surface and hollow inside. At the same time, in this embodiment, the side walls of the primary air guide cover 6 and the secondary air guide cover 7 are divided into three equal parts from top to bottom, and are respectively divided into an upper part, a middle part and a lower part; and the division standard can be adaptively adjusted.

[0030] Reference Figure 2 The first type of guide holes and the second type of guide holes are provided on the first-level guide cover 6. Specifically, the first type of guide holes includes a plurality of first guide holes 601, which are evenly distributed in the middle of the side wall of the first-level guide cover 6; the second type of guide holes includes a plurality of second guide holes 602, which are evenly distributed on the upper bottom surface of the first-level guide cover 6 and the upper part of the side wall.

[0031] At the same time, the ratio of the hole spacing to the aperture of the first guide hole 601 is in the range of 1:1 to 2:1, the ratio of the total area of ​​the first guide hole 601 to the inlet area of ​​the first-level guide cover 6 is in the range of 2:1 to 3:1, and the diameter of the first guide hole 601 is in the range of 10 to 20 mm. The ratio of the hole spacing to the aperture of the second guide hole 602 is in the range of 2:1 to 3:1, the ratio of the total area of ​​the second guide hole 602 to the inlet area of ​​the first-level guide cover 6 is in the range of 1:1 to 2:1, and the diameter of the second guide hole 602 is in the range of 30 to 40 mm. Therefore, the diameter of the second guide hole 602 on the first-level guide cover 6 is larger than the diameter of the first guide hole 601, so that the water flow can have different paths and increase the activity path of the water flow, thereby extending the reaction time between impurities and the agent in the water flow, which is conducive to the full reaction between the agent and the impurities.

[0032] Reference Figure 3 The second-level air guide cover 7 is provided with third-type air guide holes and fourth-type air guide holes. Specifically, the third-type air guide holes include a plurality of third air guide holes 701, which are evenly distributed in the middle of the side wall of the second-level air guide cover 7; the fourth-type air guide holes include a plurality of fourth air guide holes 702, which are evenly distributed in the lower part of the side wall of the second-level air guide cover 7.

[0033] Meanwhile, the ratio of the hole spacing to the aperture of the third guide hole 701 is in the range of 1:1-2:1, the ratio of the total area of ​​the third guide hole 701 to the inlet area of ​​the secondary guide cover 7 is in the range of 2:1-3:1, and the diameter of the third guide hole 701 is in the range of 15-25 mm. The ratio of the hole spacing to the aperture of the fourth guide hole 702 is in the range of 2:1-3:1, the ratio of the total area of ​​the fourth guide hole 702 to the inlet area of ​​the secondary guide cover 7 is in the range of 1:1-2:1, and the diameter of the fourth guide hole 702 is in the range of 30-50 mm. The diameter of the fourth guide hole 702 on the secondary guide cover 7 is larger than the diameter of the third guide hole 701, and the first guide hole 601 and the second guide hole 602 on the primary guide cover 6 are coordinated to further change the flow path of the water between the primary guide cover 6 and the secondary guide cover 7, and increase the complexity of the water flow path, thereby further improving the contact opportunity and time between the agent and impurities, so that the agent can fully remove impurities in the water and improve the efficiency of the water treatment process.

[0034] The hole spacing mentioned above refers to the distance between the centers of the two circular holes; and the inlet area refers to the area formed by the bottom edge of the air deflector. Specifically, in this embodiment, the air deflector is a cylindrical structure without a bottom surface and is hollow inside, and the inlet area of ​​the air deflector refers to the circular area formed by the bottom edge.

[0035] At the same time, in this embodiment, the diameter of the first-level flow guide cover 6 should be no less than 600 mm, and the height should be no less than 600 mm; at the same time, the diameter ratio of the first-level flow guide cover 6 to the diameter of the second-level flow guide cover 7 is 1:2~2:3, and the height ratio is 1:2~2:3, thereby ensuring that there is enough space for the reaction between impurities and reagents in the water flow, so that the treated water can meet the water quality standards.

[0036] During installation, the bottom ends of the primary air deflector 6 and the secondary air deflector 7 are fixedly connected to the two supporting baffles 5 by bolts, thereby ensuring the stability of the primary air deflector 6 and the secondary air deflector 7; and the primary air deflector 6 is located inside the secondary air deflector 7.

[0037] Reference Figure 1 A water treatment device based on a double-layer flow guide cover also includes a motor 9, a stirring rod 10, an impeller 11 and a dosing pipe 4.

[0038] Specifically, a through hole 8 is opened at the relative position of the upper bottom surface of the first-level air guide cover 6 and the upper bottom surface of the second-level air guide cover 7, and the stirring rod 10 passes through the through hole 8 on the upper bottom surface of the first-level air guide cover 6 and the upper bottom surface of the second-level air guide cover 7, and is vertically arranged inside the pool body 1; at the same time, the upper end of the stirring rod 10 is fixedly connected to the motor 9, and the bottom end of the stirring rod 10 is fixedly connected to the impeller 11.

[0039] During use, the motor 9 can drive the stirring rod 10 to rotate, thereby driving the impeller 11 to rotate; at the same time, in order to ensure that the impeller 11 can produce sufficient stirring on the water flow, the impeller 11 adopts a blade propulsion structure, and the number of stirring blades on the impeller 11 is 3; and the number of stirring blades can be adaptively adjusted.

[0040] In this embodiment, the impeller 11 is aligned with the first guide hole 601 at the bottom in the middle of the side wall of the first-stage guide cover 6; it can be understood that the impeller 11 is aligned with the dividing line between the middle and bottom of the side wall of the first-stage guide cover 6; at the same time, the impeller 11 is aligned with the opening of the guide tube 3; and the dosing pipe 4 is based on the guide holes on the first-stage guide cover 6 and the second-stage guide cover 7, and the outlet end of the dosing pipe 4 is set between the impeller 11 and the outlet of the guide tube 3.

[0041] Through the above arrangement, when the water flows into the pool body 1 through the outlet of the guide tube 3, it first contacts the medicine output by the dosing pipe 4 and is transported to the impeller 11 by the inertia of the water flow; and the stirring of the water flow by the impeller 11 and the inertia of the water flow during the transportation process cause the water flow to flow in a complex manner inside and outside the primary guide cover 6 and the secondary guide cover 7, so as to achieve a full reaction.

[0042] In order to ensure that impurities in the water flow can further react fully with the reagent, in this embodiment, the outlet end of the dosing pipe 4 is 8 to 10 cm away from the bottom end of the stirring blade on the impeller 11; at the same time, the angle between the plane where the stirring blade is located and the horizontal plane is in the range of 15° to 25°, and the diameter of the stirring blade on the impeller 11 is in the range of 400 to 500 mm.

[0043] Steps to use the device:

[0044] The water flows into the guide tube 3 from the water inlet 2, and flows to the output end of the dosing tube 4 under the guidance of the guide tube 3, so as to realize the initial contact and reaction between the impurities in the water flow and the reagents; then the water flow, based on its own inertia and the stirring of the stirring blades on the impeller 11, first passes through the guide holes in the upper, middle and upper bottom surface of the side wall of the primary guide cover 6 and enters the secondary guide cover 7, and then flows into the pool body 1 from the guide holes in the middle and lower part of the side wall of the secondary guide cover 7, and finally flows out through the water outlet 12.

[0045] During the operation of the above-mentioned device, the high-speed rotation of the stirring blades generates strong turbulence in the water flow, thereby increasing the turbulent kinetic energy. The increase in turbulent kinetic energy helps the water flow to contact the agent, so that the impurities in the water flow and the agent can react more fully. At the same time, the presence of the primary guide cover 6 and the secondary guide cover 7 further affects the distribution of turbulent kinetic energy, and the guide holes at different positions and different apertures on the primary guide cover 6 and the secondary guide cover 7 cause different flow velocity changes when the water flows through the primary guide cover 6 and the secondary guide cover 7, thereby causing changes in turbulent kinetic energy. Specifically, near the guide hole, the flow velocity of the water flow increases, and the turbulent kinetic energy also increases accordingly, which improves the reaction efficiency process between impurities and agents in the water flow; at the same time, the shape and position of the guide cover will also affect the flow path of the water flow, thereby affecting the distribution of turbulent kinetic energy.

[0046] Finally, when the device is in use, it can be placed on the top of the pool body 1 through the cover plate 13, and at the same time, a hole of the same size as the motor 9 is opened on the cover plate 13, and the connection between the motor 9 and the cover plate 13 is achieved by bolts, so as to fix the motor 9.

[0047] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
