Description

Technical Field

[0001] The utility model belongs to the technical field of sewage aeration treatment, and relates to an aeration energy-saving system, in particular to an aeration energy-saving device for sewage treatment. Background Art

[0002] In the sewage treatment process, it is often necessary to use an aerator to aerate and oxygenate the water body or to use a flow pusher to create a water flow in the water pool and form a water circulation. In the prior art, an aerator and a flow pusher are often installed in the sewage treatment pool at the same time so that it has both the functions of aeration and flow pushing to meet the needs of use. In the sewage treatment process, the bubbles formed by the air injected by the aerator in the water are relatively large, the gas-liquid contact area is small, the solubility of air in the sewage is low, and the biological reaction efficiency in the water is low. If it is necessary to ensure the dissolved oxygen content in the sewage, it is necessary to increase the air supply, that is, the aeration volume, which mainly increases the air supply pressure of the air compressor and increases the aeration cost. In addition, the flow pusher of the prior art can only create water flow in the water and has a single function. Combining the flow pusher with the aerator cannot significantly increase the solubility of air in the water.

[0003] Based on this, it is necessary to provide an aeration system that can achieve push flow, increase the solubility of compressed air in sewage, and save electricity. Utility Model Content

[0004] The utility model aims to provide an energy-saving aeration device for sewage treatment, so as to solve the technical problems existing in the prior art of single function of aerators and flow pushers, low solubility of air in sewage and high aeration cost.

[0005] In order to achieve the above purpose, the specific technical solutions of the present utility model are as follows:

[0006] A sewage treatment aeration energy-saving device includes an aeration mechanism, a flow-pushing mechanism, a bubble cutting mechanism, and a control mechanism electrically connected thereto. The aeration mechanism includes a guide tube, an air inlet connection port provided at the head end of the guide tube and connected to an air pipe of an air supply mechanism, and a guide plate. The guide plates are multiple and evenly distributed on the inner wall of the guide tube.

[0007] The flow-pushing mechanism is arranged outside the aeration mechanism and includes a driving part and a transmission part. The transmission part is sleeved on the outer wall of the guide tube and drives the guide tube to rotate. The driving part is arranged on the stabilizing seat and is in transmission connection with the transmission part.

[0008] The bubble cutting mechanism is arranged at the end of the guide tube, and the cutting channel of the bubble cutting mechanism is communicated with the interior of the guide tube.

[0009] The aeration mechanism also includes a conical cylinder A, the small end of which is arranged at the head end of the guide cylinder through a bearing, the large end of which is closed and evenly provided with multiple water inlet holes connected to the interior of the guide cylinder, the side wall of the conical cylinder is a double-layer side wall structure, and the double-layer side walls are hollow to form a hollow interlayer, the air inlet connection port is arranged on the outer wall of the conical cylinder and connected to the hollow interlayer, the hollow interlayer is an air inlet channel, and a plurality of air holes are evenly distributed on the inner wall of the conical cylinder, and the air inlet channel of the conical cylinder is connected to the interior of the guide cylinder through the air holes.

[0010] The guide plates are fan-shaped or spiral-shaped and are evenly arranged on the inner wall of the guide cylinder.

[0011] The bubble cutting mechanism includes a conical tube B and a paddle. The small end of the conical tube B is fixed to the end of the guide tube, and the large end opening points to the outside. The paddle is fixed on the inner wall of the conical tube B.

[0012] The driving part of the flow-pushing mechanism includes a submersible motor, and the transmission part of the flow-pushing mechanism includes a driving gear and a driven gear. The driven gear is sleeved on the outer wall of the guide tube and is key-connected to the outer wall of the guide tube. The guide tube and the conical tube B have the freedom to rotate relative to the conical tube A under the drive of the submersible motor, the driving gear and the driven gear.

[0013] The outer covers of the driving gear and the driven gear are provided with protective covers.

[0014] It also includes a lifting mechanism, which includes a lifting connecting seat, a lifting rail and a lifting rope. The lifting rail is vertically arranged along the side wall of the sewage treatment tank, and the upper end is fixed to the edge of the sewage treatment tank. One end of the lifting connecting seat is hinged to the driving part of the flow-pushing mechanism, and the other end fits the lifting rail into its internal space and cooperates with the lifting rail through a guide wheel. The lower end of the lifting rope is fixed to the lifting connecting seat, and the upper end is connected to a manual or electric winch.

[0015] The beneficial effects of the utility model are as follows: the utility model provides an aeration energy-saving device for sewage treatment, and by arranging the aeration mechanism in the middle of the flow-pushing mechanism, the two are cleverly combined into a whole, so that the device has the dual functions of flow-pushing and aeration. After the flow-pushing mechanism forms a water flow, the water flow is driven to flow into the aeration mechanism and mixed with the air in the aeration mechanism, and the air is quickly output along the guide tube, thereby increasing the aeration speed and promoting the preliminary fusion of air and water flow.

[0016] By setting a bubble cutting mechanism at the end of the aeration mechanism, the bubble cutting mechanism is used to stir and cut the gas-water mixture at high speed, which can effectively cut the air output by the aeration mechanism into small bubbles, greatly increasing the gas-liquid contact area, thereby effectively dissolving the oxygen in the air in the sewage, promoting biological reactions in the water, and promoting uniform mixing and oxygenation of the water body.

[0017] The technical solution provided by the utility model realizes the organic combination of aeration and plug flow, which can effectively increase the solubility of oxygen in the air in sewage, so that the sewage can have a higher dissolved oxygen content with a lower aeration volume, thereby saving aeration volume and aeration costs, and is suitable for promotion and application in the field of sewage treatment.

[0024] In order to better understand the purpose, structure and function of the present invention, the present invention is described in further detail below with reference to the accompanying drawings.

[0025] like Figure 1 、 Figure 2As shown, the utility model provides an aeration energy-saving device for sewage treatment, which includes an aeration mechanism, a flow pushing mechanism, a bubble cutting mechanism, and a control mechanism electrically connected thereto. The aeration mechanism includes a guide tube 1, an air inlet connection port 3 provided at the head end of the guide tube 1, connected to an air delivery pipe 2 of an air supply mechanism, and a guide plate 4. The number of the guide plates 4 is multiple, such as Figure 2 、 Figure 4 As shown, they are evenly distributed on the inner wall of the guide tube 1;

[0026] The flow-pushing mechanism is arranged outside the aeration mechanism and includes a driving part and a transmission part. The transmission part is sleeved on the outer wall of the guide tube 1 to drive the guide tube 1 to rotate. The driving part is arranged on the stabilizing seat 23 and is in transmission connection with the transmission part.

[0027] By sheathing the transmission part on the outer wall of the guide tube 1 and using the driving part to drive the transmission part, a water flow is formed around the guide tube 1. The continuous operation of the flow-pushing mechanism drives the water flow into the guide tube 1, thereby preliminarily mixing and stirring with the compressed air delivered into the guide tube 1 from the air inlet connection port 3 by the air delivery pipe 2, so that the oxygen in the air is preliminarily dissolved in the water. Driven by the water flow, the compressed air can be quickly output along the guide tube 1 to aerate the water body.

[0028] In addition, a bubble cutting mechanism is arranged at the end of the guide tube 1, and the cutting channel of the bubble cutting mechanism is connected to the interior of the guide tube 1, and the water flow containing a large number of air bubbles is cut by high-speed rotation, and the air bubbles are cut into small bubbles, which can greatly increase the gas-liquid contact area, thereby dissolving the oxygen in the air more quickly and fully into the sewage, promoting biological reactions in the sewage, and promoting uniform mixing and oxygenation of the water body.

[0029] Specifically, such as Figure 2 、 Figure 3 、 Figure 5 As shown, the aeration mechanism in this embodiment also includes a conical cylinder A5, the small end of which is arranged at the head end of the guide cylinder 1 through a bearing, and has the freedom to rotate relative to the guide cylinder 1 so as to remain stationary during the rotation of the guide cylinder 1. The large end of the conical cylinder A5 is closed and evenly provided with a plurality of water inlet holes 6 connected to the interior of the guide cylinder 1 for introducing the water flow generated by the flow-pushing mechanism. The side wall 20 of the conical cylinder A5 is a double-layer side wall structure, and the double-layer side walls are hollow to form a hollow interlayer. The air inlet connection port 3 is arranged on the outer wall 51 of the conical cylinder and is connected to the hollow interlayer. The hollow interlayer is an air inlet channel 7, and a plurality of air holes 8 are evenly distributed on the inner wall 52 of the conical cylinder. Figure 2As shown, it is used to disperse the compressed air into multiple small air flows to diffuse into the sewage, increase the gas-liquid contact area, and promote the dissolution of oxygen. The air inlet channel 7 of the conical cylinder is connected with the interior of the guide cylinder 1 through the air hole 8. After the flow-pushing mechanism works to generate water flow around the guide cylinder 1, the water flow enters the guide cylinder 1 through the water inlet hole 6, and flows to the cheongsam cutting mechanism after contacting multiple small air flows.

[0030] Further, such as Figure 2 、 Figure 4 As shown, the guide plates 4 are fan-shaped or spiral-shaped and are evenly arranged on the inner wall of the guide tube 1. In this embodiment, fan-shaped is preferred. The arrangement of the guide plates 4 can initially cut the airflow input by the guide tube 1 during its rotation, thereby initially increasing the gas-liquid contact area.

[0031] In addition, if Figure 1 、 Figure 2 As shown, the bubble cutting mechanism includes a conical barrel B9 and a paddle 10. The small end of the conical barrel B9 is fixed to the end of the guide barrel 1, and the large end is open and points outward. The paddle 10 is fixed to the inner wall of the conical barrel B9. When the guide barrel 1 rotates, it drives the conical barrel B9 to rotate. Driven by the conical barrel B9, the paddle 10 rotates at high speed without a shaft, performing a high-speed secondary cutting of the gas-liquid mixture conveyed along the guide barrel 1.

[0032] Furthermore, the drive unit of the flow-propelling mechanism includes a submersible motor 11, and the transmission unit of the flow-propelling mechanism includes a driving gear 13 and a driven gear 14. The driven gear 14 is mounted on the outer wall of the guide tube 1 and keyed to the outer wall of the guide tube 1. The guide tube 1 and the conical tube B9 are free to rotate relative to the conical tube A5 under the drive of the submersible motor 11, the driving gear 13, and the driven gear 14. At the same time, to protect the transmission unit, the driving gear 13 and the driven gear 14 in this embodiment are externally covered with a protective cover 15, which is mounted on the guide tube 1 via a bearing.

[0033] Furthermore, in order to be able to remove it from the sewage when the system needs maintenance, e.g. Figure 1As shown, in this embodiment, it also includes a lifting mechanism, which includes a lifting connecting seat 16, a lifting rail 17 and a lifting rope 18. The lifting rail 17 is vertically arranged along the side wall 20 of the sewage treatment tank, and the upper end is fixed to the edge 21 of the sewage treatment tank to provide guidance for the lifting of the equipment. One end of the lifting connecting seat 16 is hinged to the submersible motor 11, and the other end is fitted with the lifting rail 17 in its internal space and then cooperates with the lifting rail 17 through a guide wheel 22. In order to improve the stability of the submersible motor 11 and other mechanisms during the lifting process, in this embodiment, the lifting connecting seat 16 is further provided with another secondary hinge point with the submersible motor 11 between the hinge point with the drive part and the guide wheel 22; the lower end of the lifting rope 18 is fixed to the lifting connecting seat 16, and the upper end is connected to a manual or electric winch, which provides lifting power for the equipment through the manual or electric winch. In addition, in order to improve the stability of the submersible motor 11 when placed on the bottom 19 of the sewage treatment tank, in this embodiment, the submersible motor 11 is fixed on a stabilizing seat 23 and placed on the bottom 19 of the tank through the stabilizing seat 23 .

[0034] In addition, in order to control the conical cylinder A5 to remain stationary when the guide cylinder 1 rotates to avoid entanglement of the air pipe, the air inlet connection port 3 and the lifting connection seat 16 can also be fixedly connected using a connecting piece. The staff can connect them by themselves according to the specific situation. No specific restrictions are made in this embodiment.
