Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a cyclone flotation type water treatment separation tower. Background Technology

[0002] With water scarcity and increasingly severe water pollution problems, greywater reuse has become a key path for water conservation and pollution reduction. Greywater treatment requires the removal of impurities such as suspended solids, grease, and colloids. Cyclone separation uses centrifugal force to accelerate particle sedimentation, while air flotation technology uses microbubble adhesion to improve the separation effect of light pollutants. The cyclone air flotation process, which combines the two, has gradually become a research hotspot in greywater treatment due to its high efficiency and synergistic potential.

[0003] When existing cyclone flotation separation towers are in operation, scum and sediment tend to accumulate inside the tower. In particular, after grease and suspended solids are mixed, conventional sludge discharge structures (such as scrapers) are prone to clogging, increasing operation and maintenance costs. The separation boundary between oil discharge and water discharge is blurred, resulting in incomplete grease recovery and water waste. At the same time, the flow fields of cyclone and flotation tend to interfere with each other. For example, the centrifugal force of cyclone can disrupt the uniform distribution of air flotation bubbles, and the upward flow of air flotation weakens the centrifugal effect of cyclone, reducing the overall separation efficiency. Utility Model Content

[0004] This utility model mainly provides a cyclone air flotation type water treatment separation tower that facilitates the removal of impurities and oil.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cyclone flotation type water treatment separation tower, comprising: a tower body, an arc tube fixed and connected to the bottom and near the center of the tower body, a fixing block fixedly connected to the outer arc wall of the arc tube, a rotating rod provided at the center of the arc tube, the bottom of the rotating rod penetrating the arc tube and the fixing block and rotatably connected to its bearing, a cyclone fan blade plate fixedly connected to the surface of the rotating rod near the top, a vertical cylinder provided inside the tower body near the top center, a vortex plate fixedly fitted on the surface of the vertical cylinder, the other end of the vortex plate fixedly connected to the inner wall of the tower body, and an oil discharge pipe fixed and connected to the bottom of the vertical cylinder, one end of the oil discharge pipe penetrating the tower body and fixedly connected to it.

[0006] Preferably, the bottom of the tower body is fixedly connected with support legs at equal intervals near the edge. This arrangement enables the support legs to support the bottom of the tower body.

[0007] Preferably, a cross plate is sleeved and fixedly connected to the surface of the rotating rod and below the swirl fan blade plate. All four ends of the cross plate are fixedly connected to the inner wall of the tower. Through the above arrangement, the cross plate can be used to fix the top of the rotating rod.

[0008] Preferably, a ring plate is fixedly connected to the top of the cross plate and at the edge of the swirl fan blade plate. With the above arrangement, the ring plate can constrain the swirl boundary and prevent the water flow from short-circuiting.

[0009] Preferably, a drive motor is fixedly installed at the bottom of the fixing block, and the output end of the drive motor is fixedly connected to the bottom of the rotating rod. With the above arrangement, the drive motor can drive the rotating rod to rotate.

[0010] Preferably, a water inlet pipe is fixed and connected to the surface of the tower body near the top, and a drain pipe is fixed and connected to the surface of the tower body at one end of the vortex plate. With the above arrangement, the effects of water inlet and drainage can be achieved.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, through the flow field design of swirl fan blade plate + vortex plate, heavy particles are separated by swirling flow, while light pollutants are adsorbed by air flotation. This can achieve the dual purification effect of centrifugation and air flotation, thereby improving the removal rate of suspended solids and oil and ensuring that the effluent meets the standards.

[0013] 2. In this utility model, the drive motor drives the rotating rod to rotate, and the fan blades disturb the water flow to form a stable swirling field, which enhances centrifugal separation. The vortex plate guides the water flow after swirling into the vertical cylinder in an orderly manner, avoiding turbulent flow field. The vertical cylinder provides an independent space for oil discharge, which can achieve the effect of collecting oil by utilizing the density difference between oil and water. This can reduce the interference with swirling and air flotation, thereby improving the synergistic efficiency. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a cyclone flotation type water treatment separation tower, comprising: a tower body 1, an arc tube 3 fixed and connected to the bottom and near the center of the tower body 1, a fixing block 4 fixedly connected to the outer arc wall of the arc tube 3, a rotating rod 5 provided at the center of the arc tube 3, the bottom of the rotating rod 5 passing through the arc tube 3 and the fixing block 4 and rotatably connected to its bearing, a cyclone fan blade 9 fixedly connected to the surface of the rotating rod 5 near the top, a vertical cylinder 11 provided inside the tower body 1 near the top center, a vortex plate 10 fixedly fitted on the surface of the vertical cylinder 11, the other end of the vortex plate 10 fixedly connected to the inner wall of the tower body 1, and an oil drain pipe 14 fixedly connected to the bottom of the vertical cylinder 11, one end of the oil drain pipe 14 passing through the tower body 1 and fixedly connected to it. Through the above arrangement, the rotating rod 5 can be rotated, and the cyclone fan blade 9 can be rotatably connected to its bearing. The fan blade 9 rotates with the rotating rod 5, disturbing the water in the tower body 1 to form a high-speed vortex. After the water enters the tower body 1, the heavy particles are enriched towards the tower wall under the action of centrifugal force, slide down the wall to the bottom of the tower, and are discharged through the arc pipe 3. During the flow of the water (combined with the pressure and flow rate of the inlet pipe 13), the water body naturally dissolves air or through the implicit dissolved air system (such as the dissolved air tank connected to the equipment, which is not detailed in the manual but is a conventional adaptation), releasing 10-100μm microbubbles in the vortex field, adhering to light pollutants such as grease and colloids. The vortex plate 10 guides the water flow after vortex into the vertical cylinder 11. Utilizing the low-speed flow field in the vertical cylinder 11, the pollutants after air flotation float to the top of the vertical cylinder 11. The grease is further separated due to the density difference and collected through the oil drain pipe 14, while the purified water is discharged through the drain pipe 12.

[0022] like Figure 1 As shown, support legs 2 are fixedly connected at equal intervals to the bottom of the tower body 1 and near the edge. Through the above arrangement, the support legs 2 can support the bottom of the tower body 1.

[0023] like Figure 2 As shown, a cross plate 7 is fitted and fixedly connected to the surface of the rotating rod 5 and below the swirl fan blade plate 9. All four ends of the cross plate 7 are fixedly connected to the inner wall of the tower body 1. Through the above arrangement, the cross plate 7 can be used to fix the top of the rotating rod 5.

[0024] like Figure 3 As shown, a ring plate 8 is fixedly connected to the top of the cross plate 7 and at the edge of the swirl fan blade plate 9. Through the above arrangement, the ring plate 8 can constrain the swirl boundary and prevent the water flow from short-circuiting.

[0025] like Figure 4 As shown, a drive motor 6 is fixedly installed at the bottom of the fixed block 4, and the output end of the drive motor 6 is fixedly connected to the bottom of the rotating rod 5. With the above arrangement, the drive motor 6 can drive the rotating rod 5 to rotate.

[0026] like Figure 1 As shown, a water inlet pipe 13 is fixed and connected to the surface of the tower body 1 near the top, and a drain pipe 12 is fixed and connected to the surface of the tower body 1 at one end of the vortex plate 10. Through the above arrangement, the effects of water inlet and drainage can be achieved.

[0027] The operating method and working principle of this device are as follows: When the drive motor 6 starts, it drives the rotating rod 5 to rotate. The swirl fan blades 9 move with the rotating rod 5, disturbing the water in the tower body 1 to form a high-speed swirling flow. After the water enters the tower body 1, the heavy particles are concentrated towards the tower wall under the action of centrifugal force, slide down the wall to the bottom of the tower, and are discharged through the arc pipe 3. During the flow of the water (combined with the pressure and flow rate of the inlet pipe 13), the water body naturally dissolves gas or through an implicit dissolved gas system (such as an external dissolved gas tank, which is not detailed in the manual but is a common adaptation). In the swirling flow field, 10-100μm microbubbles are released to adhere to light pollutants such as grease and colloids. The vortex plate 10 guides the swirling water flow into the vertical cylinder 11. Utilizing the low-speed flow field within the vertical cylinder 11, the pollutants after air flotation float to the top of the vertical cylinder 11. Grease is further separated due to density differences and collected through the oil drain pipe 14, while the purified water is discharged through the drain pipe 12. The cross plate 7 fixes the rotating rod 5, ensuring the rotational stability of the swirling fan blade 9. The ring plate 8 constrains the swirling boundary to prevent short-circuiting of the water flow. The spiral structure of the vortex plate 10 ensures an orderly connection between the swirling flow and the upward flow within the vertical cylinder 11, avoiding flow field conflicts and ensuring continuous operation of swirling sedimentation, air flotation separation, and water discharge.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
