Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an energy-saving agitator for wastewater treatment. Background Technology

[0002] Energy-saving mixers for wastewater treatment are important equipment in the wastewater treatment process. They are designed to reduce energy consumption while achieving efficient mixing through optimized design and technology application, thereby improving the overall efficiency and economy of wastewater treatment.

[0003] Existing patents, such as Chinese Patent Publication No. CN216125500U, disclose a wastewater treatment mixer, including a mixing tank. The mixing tank contains a mixing device, which includes a rotating rod rotatably connected to the upper wall of the mixing tank. A disc is fixedly connected to the outer surface of the rotating rod, and a mixing rod is fixedly connected to the lower surface of the disc. The mixing rod agitates the wastewater inside the mixing tank. During wastewater treatment, wastewater is poured into the mixing tank through a water pipe. The motor is then started, causing the shaft to rotate, which in turn drives a first gear. A second gear then drives the rotating rod. Simultaneously, the mixing rod below the disc agitates the wastewater, accelerating the treatment process. At the same time, a scrubbing plate connected to the fixed rod continuously scrubs the inner wall of the mixing tank, preventing dirt from accumulating on the tank wall during wastewater treatment and facilitating cleaning.

[0004] Although the aforementioned patented technology uses a scrubbing plate connected to a fixed rod to continuously scrub the inner wall of the mixing tank, preventing dirt from sticking to the tank wall during wastewater treatment and facilitating cleaning, the aforementioned agitator is prone to issues such as sediment not being stirred to the top and floating matter not being stirred to the bottom during wastewater mixing, which can easily affect the uniformity of mixing. Therefore, an energy-saving agitator for wastewater treatment is needed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the above-mentioned patented technology that the wastewater treatment energy-saving agitator cannot stir the sediment to the top and the floating matter cannot be stirred to the bottom during the stirring process, and to propose an energy-saving agitator for wastewater treatment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an energy-saving agitator for sewage treatment, comprising an agitator tank, an inner cylinder of which is provided, a top cover installed on the top of which is fixedly connected to a fixed plate embedded in and fixedly connected to the center of the top cover, a rotating rod rotatably connected through and bearing the center of the fixed plate, a conveying blade sleeved and fixedly connected to the surface of the rotating rod and located inside the cylinder, a rotating fan blade sleeved and fixedly connected to the surface of the rotating rod and located above the conveying blade, and an agitating fan blade sleeved and fixedly connected to the surface of the rotating rod and located below the agitator tank.

[0007] Preferably, the bottom of the mixing tank is fixedly connected with support legs at equal intervals near the edge, and each support leg is fixedly connected with a trapezoidal block at its bottom.

[0008] Preferably, the top of the cylinder is fixedly connected with connecting rods at equal intervals, and the top of the connecting rods is fixedly connected to the bottom of the fixed plate.

[0009] Preferably, the conveying blades are adapted to the conveying direction of the rotating fan blades, and the stirring fan blades are in the opposite direction to the blades of the rotating fan blades.

[0010] Preferably, a drive motor is fixedly connected to the top of the fixed disk, and the output end of the drive motor is fixedly connected to the top of the rotating rod.

[0011] Preferably, the outer arc edge of the stirring blade is in contact with the inner arc wall of the bottom of the stirring tank.

[0012] Preferably, a limiting ring is fixedly connected to the bottom of the top cover, and the limiting ring is adapted to the inner wall of the mixing tank.

[0013] Preferably, a feed arc pipe is fixedly connected to the surface and near the top of the mixing tank, and a discharge cylinder is fixedly connected to the bottom and near the center of the mixing tank. A magnetic valve is fixedly installed on the surface of the discharge cylinder, and a fixing rod is fixedly connected between the discharge cylinder and the support leg.

[0014] Preferably, the top of the feeding arc tube is fixed and connected to a feeding funnel, and a feeding cover is fixedly installed on the top of the feeding funnel.

[0015] Preferably, a controller is fixedly mounted on the surface of the mixing tank, and a control panel is mounted on the surface of the controller.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] In this invention, the rotating rod can drive the rotating fan blades to rotate, which can create a downward vortex on the surface of the sewage, allowing floating objects to enter the inside of the cylinder. At the same time, the rotating rod will also drive the conveying blades to rotate, transporting the floating objects and the sewage above to the bottom of the mixing tank. The sewage below will be squeezed to the top, which can achieve the effect of circulating and stirring the sewage from top to bottom, thereby improving the uniformity of vertical mixing of sewage.

[0018] In this invention, a drive motor can drive a rotating rod to rotate, which in turn drives the stirring blades to rotate, thus stirring the sewage being transported downwards. This further stirs the sewage and also allows it to be transported upwards, thereby improving the uniformity of the stirring. Attached Figure Description

Detailed Implementation

[0025] 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.

[0026] 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.

[0027] Example 1, as Figure 1-5 As shown, this utility model provides an energy-saving agitator for sewage treatment, including an agitator tank 1. The agitator tank 1 has a cylindrical cylinder 4 inside. A top cover 10 is installed on the top of the agitator tank 1. A fixed plate 9 is embedded and fixedly connected to the center of the top cover 10. A rotating rod 6 is rotatably connected to the center of the fixed plate 9 through and bearing a bearing. A conveying blade 7 is sleeved and fixedly connected to the surface of the rotating rod 6 inside the cylindrical cylinder 4. A rotating fan blade 8 is sleeved and fixedly connected to the surface of the rotating rod 6 above the conveying blade 7. A stirring fan blade 13 is sleeved and fixedly connected to the surface of the rotating rod 6 below the agitator tank 1.

[0028] The overall effect of Embodiment 1 is that, with a cylinder 4 inside the mixing tank 1, a top cover 10 installed on the top of the mixing tank 1, a fixed plate 9 embedded and fixedly connected to the center of the top cover 10, a rotating rod 6 passing through and rotatably connected to the center of the fixed plate 9, a conveying blade 7 sleeved and fixedly connected to the surface of the rotating rod 6 inside the cylinder 4, a rotating fan blade 8 sleeved and fixedly connected to the surface of the rotating rod 6 above the conveying blade 7, and a stirring fan blade 13 sleeved and fixedly connected to the surface of the rotating rod 6 below the mixing tank 1, the rotating rod 6 can rotate to drive the rotation of the cylinder 1. The rotation of the fan blade 8 creates a downward vortex on the surface of the sewage, allowing floating objects to enter the cylinder 4. At the same time, the rotating rod 6 also drives the conveying blade 7 to rotate. When the conveying blade 7 inside the cylinder 4 rotates, it generates an axial force on the surrounding fluid, pushing the sewage above to flow downwards along the inside of the cylinder 4, which can increase the vertical water exchange. The sewage below will be squeezed to the top, which helps to improve the problem of uneven mixing of the upper and lower water bodies. Furthermore, the rotation of the rotating rod 6 can drive the stirring fan blade 13 to rotate, which can stir the sewage conveyed to the bottom, thereby improving the uniformity of sewage mixing.

A limiting ring 11 is fixedly connected and adapted to the inner wall of the mixing tank 1; a feed arc pipe 17 is fixedly connected to the surface of the mixing tank 1 near the top and is connected to it; a discharge cylinder 14 is fixedly connected to the bottom of the mixing tank 1 near the center and is fixedly installed on the surface of the discharge cylinder 14; a solenoid valve 15 is fixedly installed on the surface of the discharge cylinder 14 and a fixing rod 16 is fixedly connected between the discharge cylinder 14 and the support leg 2; a feed funnel 18 is fixedly connected to the top of the feed arc pipe 17 and is fixedly installed on the top of the feed funnel 18; a controller 19 is fixedly installed on the surface of the mixing tank 1 and a control panel 20 is installed on the surface of the controller 19.

[0030] The overall effect of embodiment 2 is as follows: Support legs 2 are fixedly connected at equal intervals to the bottom and near the edge of the mixing tank 1. Trapezoidal blocks 3 are fixedly connected to the bottom of each support leg 2, which supports the bottom of the mixing tank 1 and stabilizes the mixing tank 1. Connecting rods 5 are fixedly connected at equal intervals to the top of the cylinder 4. The top of the connecting rods 5 is fixedly connected to the bottom of the fixed plate 9, which fixes the cylinder 4. The conveying blades 7 and rotating fan blades 8 are matched in conveying direction, and the stirring fan blades 13 and rotating fan blades 8... The blades of the rotating fan blade 8 are in opposite directions, which allows the conveying blade 7 and the rotating fan blade 8 to drive the sewage downwards, while the stirring fan blade 13 can drive the sewage upwards. A drive motor 12 is fixedly connected to the top of the fixed plate 9, and the output end of the drive motor 12 is fixedly connected to the top of the rotating rod 6, allowing the drive motor 12 to drive the rotating rod 6 to rotate. The outer arc edge of the stirring fan blade 13 is in contact with the inner arc wall of the bottom of the mixing tank 1, which allows the stirring fan blade 13 to rotate and scrape away residue from the inner arc wall of the mixing tank 1 during the stirring process. A limiting ring 11 is fixedly connected to the bottom of the cover 10. The limiting ring 11 is adapted to the inner wall of the mixing tank 1 and can limit the position of the cover 10. A feed arc pipe 17 is fixedly connected to the surface of the mixing tank 1 near the top and can be used for feeding. A discharge cylinder 14 is fixedly connected to the bottom of the mixing tank 1 near the center and can be used for discharging. A solenoid valve 15 is fixedly installed on the surface of the discharge cylinder 14 and can be used to control the discharge of the discharge cylinder 14. A fixing rod 16 is fixedly connected between the discharge cylinder 14 and the support leg 2. This makes the support leg 2 more stable; the top of the feed arc pipe 17 is fixed and connected to the feed funnel 18, which facilitates feeding; the top of the feed funnel 18 is fixedly installed with the feed cover 21, which prevents sewage gas from escaping; the surface of the mixing tank 1 is fixedly installed with the controller 19, and the surface of the controller 19 is installed with the control panel 20. Pressing the button on the control panel 20 can transmit a signal to the controller 19, at which time the controller 19 can control the sewage treatment energy-saving mixer.

[0031] Working principle: By opening the feed cover 21, the wastewater to be stirred enters the feed arc pipe 17 through the feed funnel 18 and slides into the mixing tank 1. The feed cover 21 can then be closed. The drive motor 12 is then turned on via the control panel 20 and the controller 19. The drive motor 12 drives the rotating rod 6 to rotate, which in turn drives the rotating fan blade 8 to rotate. This creates a downward vortex on the surface of the wastewater, allowing floating objects to enter the cylinder 4. At the same time, the rotating rod 6 also drives the conveying blade 7 to rotate. When the conveying blade 7 rotates inside the cylinder 4, it generates an axial force on the surrounding fluid, pushing the wastewater above down the inside of the cylinder 4, while the wastewater below is squeezed to the top. This increases vertical water exchange and helps improve the problem of uneven mixing between the upper and lower water bodies. The rotation of the rotating rod 6 also drives the stirring fan blade 13 to rotate, which stirs the wastewater conveyed to the bottom, thereby improving the uniformity of wastewater stirring. After stirring is completed, the solenoid valve 15 can be opened via the control panel 20 and the controller 19 to drain water from the discharge cylinder 14.

[0032] The wiring diagrams of the conveying blade 7, rotating fan blade 8, drive motor 12, solenoid valve 15, controller 19 and control panel 20 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the conveying blade 7, rotating fan blade 8, drive motor 12, solenoid valve 15, controller 19 and control panel 20 will not be explained in detail.

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.
