Description

Technical Field

[0001] The utility model relates to the technical field of wastewater disinfection, in particular to an industrial wastewater treatment and disinfection device. Background Art

[0002] Industrial wastewater refers to wastewater and waste liquid discharged during the production process, which contains industrial production materials, intermediates, by-products and pollutants generated in the production process that are lost with the water. It is an important cause of environmental pollution, especially water pollution. The generated wastewater needs to be disinfected. Commonly used disinfection methods include ultraviolet disinfection, chlorine dioxide disinfection, sodium hypochlorite disinfection, ozone disinfection and other methods.

[0003] When using ozone for disinfection, it is generally static disinfection. Ozone enters from the bottom of the disinfection tank and is discharged from the top. The retention time of ozone in the water body is short, and a large amount of oxygen is required to complete the disinfection operation. For this reason, we propose an industrial wastewater treatment disinfection device. Summary of the invention

[0007] Preferably, the opening is an oblique opening, allowing the water passing through the opening to flow from top to bottom, thereby forming a larger turbulence.

[0008] Preferably, a scraper is fixed on the outside of the fixing frame to scrape off the debris attached to the inner wall of the sterilizing tank.

[0009] Preferably, the outer side of the stirring frame is slidably fitted with the inner side of the disinfection tank, so that water can only pass through the opening.

[0010] Preferably, the outer side of the connection between the two openings is arc-shaped, which reduces the resistance encountered by water when entering the opening.

[0011] Preferably, the stirring frame and the fixed frame are spaced apart and distributed outside the main shaft, so that the water body is stirred more evenly.

[0012] Compared with the traditional technology, the beneficial effects of the utility model are:

[0013] 1. By setting a rotatable main shaft and stirring frame in the disinfection tank, the water can flow from top to bottom through the opening.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0021] See also Figure 1-Figure 4 The figure shows an industrial wastewater treatment and disinfection device, which relates to the field of wastewater disinfection technology, including a disinfection tank 1, an air inlet pipe 2, a liquid inlet pipe 3 and a liquid outlet pipe 4 are fixedly connected to the outer side of the bottom of the disinfection tank 1, an air outlet pipe 5 is fixedly connected to the outer side of the top of the disinfection tank 1, an ozone generator 6 is fixed to the outer end of the air inlet pipe 2, a main shaft 7 is rotatably provided in the disinfection tank 1, a motor 8 is fixed to the outer side of the top of the disinfection tank 1, the output end of the motor 8 is fixed to the main shaft 7, a stirring frame 9 is evenly fixed to the outside of the main shaft 7, through holes 10 are evenly provided in the stirring frame 9, and an auxiliary component 11 for increasing the turbulence of the water body is provided on the outside of the main shaft 7.

[0022] Some implementation methods of the present application are described in detail below with reference to the accompanying drawings:

[0023] See also Figure 1-Figure 4 By arranging a rotatable stirring frame 9 in the disinfection tank 1, the water body is allowed to flow through the opening 10, and at the same time, the turbulence effect of the water body is improved through the auxiliary component 11, and the oxygen bubbles entering the disinfection tank 1 are dispersed, thereby increasing the contact area and contact time between oxygen and water body, and reducing the amount of oxygen required for disinfection.

[0024] Among them, the auxiliary component 11 includes a rotating shaft 12, a plurality of fixing frames 13 are evenly fixed on the outside of the main shaft 7, an inner cavity 14 is fixed in the main shaft 7, a fixed shaft 15 is fixed in the disinfection tank 1, the fixed shaft 15 passes through the inside of the main shaft 7, and a plurality of first bevel gears 16 are evenly fixed on the fixed shaft 15. A plurality of rotating shafts 12 are evenly arranged in the fixing frame 13, and the rotating shaft 12 is rotatably connected to the fixing frame 13. One end of the rotating shaft 12 close to the main shaft 7 passes through the outside of the main shaft 7, and one end of the rotating shaft 12 located in the inner cavity 14 is fixed with a second bevel gear 17, and the second bevel gear 17 is meshingly connected with the first bevel gear 16. A stirring blade 18 is evenly fixed on the outside of the rotating shaft 12 to increase the turbulence of the water body.

[0025] At the same time, the outer side of the stirring frame 9 is slidably fitted with the inner side of the disinfection tank 1, so that water can only pass through the opening 10. The outer side of the connection between the two openings 10 is arc-shaped, which reduces the resistance encountered by the water when entering the opening 10.

[0026] The ozone generator 6 pumps oxygen into the disinfection tank 1, and the operation of the motor 8 drives the main shaft 7 to rotate, thereby driving the stirring frame 9 and the fixed frame 13 to rotate together. The water body and oxygen bubbles first flow out through the opening 10 and reach the fixed frame 13. As the main shaft 7 rotates, the second bevel gear 17 rolls on the first bevel gear 16, thereby driving the rotating shaft 12 and the stirring blade 18 to rotate, stirring the water body and oxygen discharged to the fixed frame 13, breaking up the oxygen bubbles in the water body, increasing the contact area and contact time between oxygen and water, and reducing the amount of oxygen required for disinfection.

[0027] It is worth noting that the stirring frame 9 and the fixing frame 13 are spaced apart and distributed outside the main shaft 7, so that the water body is stirred more evenly.

[0028] In addition, the opening 10 is an oblique opening, so that the water passing through the opening 10 flows from top to bottom, thereby forming a larger turbulence.

[0029] See also Figure 2 In this embodiment, a scraper 19 is fixed to the outside of the fixing frame 13 to scrape off the debris attached to the inner wall of the sterilizing tank 1.
