Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a hydraulic mixing device. Background Technology

[0002] Wastewater treatment is the process of removing pollutants from water bodies through physical, chemical, or biological methods to meet discharge or reuse standards. An anoxic tank is a treatment device in the wastewater treatment process, typically located between the primary sedimentation tank and the aerobic tank in the wastewater treatment system. It is used to remove organic matter and pollutants such as nitrogen and phosphorus. During operation, a stirring device is required to agitate the liquid inside the anoxic tank.

[0003] A hydraulic mixing device, disclosed in CN202224078U, includes a reducer, a short pipe, a sleeve, a base plate, and a support plate. The reducer is located at the top of the short pipe, and the lower middle part of the short pipe is located inside the sleeve. The short pipe extending into the sleeve is welded and fixed to the inner wall of the sleeve by a baffle. The bottom of the sleeve is fixedly connected to the base plate by the support plate. The sleeve wall has one or more small holes, and the base plate has bolt holes. This invention enables rapid and uniform mixing of wastewater and has the advantages of good mixing effect, simple structure, and low manufacturing cost.

[0004] The existing technology has the following shortcomings: the existing mixing device usually uses a mixer to mix the wastewater. As a result, when treating wastewater in the anoxic tank, the mixer cannot fully mix the liquid in different parts of the anoxic tank. This makes it easy for some suspended solids to settle or adhere to the inner wall of the anoxic tank, which will affect the efficiency of wastewater treatment. Utility Model Content

[0005] The purpose of this invention is to provide a hydraulic mixing device that uses two diagonally arranged nozzles to propel the wastewater in the wastewater treatment tank along the direction of the nozzle outlet, causing the water in the wastewater treatment tank to swirl and ensuring thorough and uniform mixing of the liquid. This also prevents suspended solids from settling. A fixing mechanism can be used to secure the mixing mechanism, ensuring its stability during operation, thereby addressing the aforementioned shortcomings in the technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic mixing device, including a wastewater treatment tank, and further including a fixing mechanism installed on the top and one end of the wastewater treatment tank, and a mixing mechanism disposed inside the fixing mechanism;

[0007] The stirring mechanism includes a water inlet pipe, which is located on the outer wall of one end of the wastewater treatment tank. A water pump is installed at the water inlet end of the water inlet pipe, and a water supply pipe is connected to the water outlet end of the water inlet pipe via a flange. Both water outlet ends of the water supply pipe are connected to connecting pipes via flanges, and nozzles are installed at the bottom of both connecting pipes.

[0008] Preferably, the fixing mechanism includes two fixing frames and two rotating shafts. The two fixing frames are respectively fixedly installed on both sides of the outer wall of one end of the wastewater treatment tank, and the two fixing frames are respectively movably sleeved on the outer walls of both sides of the inlet pipe.

[0009] Preferably, the top and bottom of the inner walls of the two fixing frames are threaded with fastening bolts, and the outer wall of the fastening bolt away from the fixing frame is threadedly connected to the inner wall of the wastewater treatment tank.

[0010] Preferably, the two rotating shafts are rotatably installed at one end and one side of the top of the wastewater treatment tank, respectively, and transmission gears are fixedly sleeved at the adjacent ends of the two rotating shafts, and the two transmission gears mesh with each other.

[0011] Preferably, a servo motor is fixedly installed on one side of the top end of the wastewater treatment tank, and the servo motor is connected to the adjacent rotating shaft through an output shaft drive.

[0012] Preferably, each of the two rotating shafts is fixedly fitted with a snap-fit ​​plate, and the two snap-fit ​​plates are movably connected to the outer walls of the water supply pipes in two different flow directions.

[0013] Preferably, multiple connecting bolts are threaded into the inner walls of the outer sides of the bottom of both connecting pipes, and the bottom of the connecting bolts is threaded to the inner wall of the outer side of the top of the adjacent nozzle.

[0014] Preferably, the two nozzles are arranged diagonally, and the water outlets of the two nozzles are arranged in parallel.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. Clean water can be delivered to the water supply pipe through the inlet pipe equipped with a water pump, and then the clean water can be delivered to the nozzles through the connecting pipe. The two nozzles set diagonally can spray water along the inner walls of both ends of the wastewater treatment tank, so that the high-pressure water flow can push the liquid inside the wastewater treatment tank into a swirling state, thereby fully agitating the liquid inside the wastewater treatment tank, so that the liquid inside the tank can be fully mixed evenly, while preventing the sedimentation of suspended solids in the tank, thus ensuring the wastewater treatment effect of the anoxic tank;

[0017] 2. The servo motor drives one of the rotating shafts, which in turn causes the other rotating shaft to rotate under the transmission of two gears. This allows the two clamping plates to clamp and fix the water pipe, and the two fixing brackets to fix the water inlet pipe, thus ensuring the stability of the stirring mechanism during operation.

[0028] This utility model provides, for example Figure 1 The hydraulic mixing device shown includes a wastewater treatment tank 1, a fixing mechanism 2 installed on the top and one end of the outer wall of the wastewater treatment tank 1, and a mixing mechanism 3 disposed inside the fixing mechanism 2. The wastewater treatment tank 1 is an anoxic tank in sewage treatment and can treat sewage.

[0029] To facilitate the mixing of wastewater, such as Figure 1-2 and Figure 5 As shown, the stirring mechanism 3 includes a water inlet pipe 301, which is installed on the outer wall of one end of the wastewater treatment tank 1. A water pump 302 is installed at the water inlet end of the water inlet pipe 301, and a water delivery pipe 303 is connected to the water outlet end of the water inlet pipe 301 by a flange. Both water outlet ends of the water delivery pipe 303 are connected to connecting pipes 304 by flanges. Both connecting pipes 304 are equipped with nozzles 305 at their bottoms. The water pump 302 can transport clean water through the water inlet pipe 301 to the water delivery pipe 303, and then the clean water can be transported to the nozzles 305 through the two connecting pipes 304. The two diagonally arranged nozzles 305 can generate thrust on the clean water inside the wastewater treatment tank 1, making it swirling, so that the liquid in the tank can be fully mixed and uniform, while avoiding the sedimentation of suspended solids.

[0030] To ensure that the inlet pipe 301 is stably fixed to the outer wall of one end of the wastewater treatment tank 1, such as Figure 1-4 As shown, the fixing mechanism 2 includes two fixing frames 201 and two rotating shafts 203. The two fixing frames 201 are respectively fixedly installed on both sides of the outer wall of one end of the wastewater treatment tank 1. The two fixing frames 201 are respectively movably sleeved on the outer walls of both sides of the inlet pipe 301. The top and bottom of the inner walls of the two fixing frames 201 are threaded with fastening bolts 202. The outer wall of the end of the fastening bolt 202 away from the fixing frame 201 is threadedly connected to the inner wall of the wastewater treatment tank 1. By the fastening bolt 202 penetrating the inner wall of the fixing frame 201 and threadedly connecting to the inner wall of the wastewater treatment tank 1, the two fixing frames 201 can install and fix the inlet pipe 301, thereby enabling the inlet pipe 301 to be stably installed on the outer wall of one end of the wastewater treatment tank 1.

[0031] To ensure the stability of water pipe 303 during operation, such as Figure 2 and Figure 4-5 As shown, two rotating shafts 203 are rotatably installed at one end and one side of the top of the wastewater treatment tank 1, respectively. A transmission gear 204 is fixedly sleeved at the adjacent end of each rotating shaft 203, and the two transmission gears 204 mesh with each other. A servo motor 205 is fixedly installed on one side of the top of the wastewater treatment tank 1. The servo motor 205 is connected to the adjacent rotating shaft 203 via an output shaft transmission connection. A snap-fit ​​plate 206 is fixedly sleeved on the outer side of each rotating shaft 203. The two snap-fit ​​plates 206 are movably connected to the outer walls of the two flow directions of the water supply pipe 303, respectively. Through a control terminal, the servo motor 205 drives one of the adjacent rotating shafts 203 to rotate. The two meshing transmission gears 204 can then drive the other rotating shaft 203 to rotate, which in turn drives the two snap-fit ​​plates 206 to rotate. This allows the two snap-fit ​​plates 206 to snap and fix the outer walls of the two outlet ends of the water supply pipe 303, ensuring the water supply pipe 303 remains stable within the wastewater treatment tank 1.

[0032] To facilitate the installation and replacement of the 305 spray head by staff, such as Figure 2 and Figure 5 As shown, multiple connecting bolts 306 are threaded into the inner walls of the outer sides of the bottom of both connecting pipes 304. The bottom of the connecting bolts 306 is threaded to the inner wall of the outer side of the top of the adjacent nozzle 305. The two nozzles 305 are arranged diagonally, and the water outlets of the two nozzles 305 are arranged in parallel. The connecting bolts 306 penetrate the inner wall of the connecting pipes 304 and are threaded to the inner wall of the top of the adjacent nozzles 305, which allows the staff to easily install and replace the nozzles 305. At the same time, the two diagonally arranged nozzles 305 and the parallel water flow direction can stably push and stir the liquid inside the wastewater treatment tank 1.

[0033] In the wastewater treatment process, connecting bolts 306 penetrate the inner wall of connecting pipe 304 and are threadedly connected to the inner wall of nozzle 305, thus connecting nozzle 305 to connecting pipe 304. Then, the two connecting pipes 304 are respectively connected to the two outlet ends of water supply pipe 303. Water supply pipe 303 is then placed at the top inner side of wastewater treatment tank 1, positioning the two nozzles 305 at two diagonal positions within wastewater treatment tank 1. A control terminal then activates servo motor 205, causing adjacent rotating shafts 203 to rotate. Through the meshing of two transmission gears 204, another rotating shaft 203 rotates, thereby driving two... The snap-fit ​​plate 206 rotates to snap and fix the outer walls of the two outlet ends of the water supply pipe 303, so that the water supply pipe 303 remains stable inside the wastewater treatment tank 1. Then, the inlet pipe 301 is installed on one end of the outer wall of the wastewater treatment tank 1 and connected to the inlet end of the water supply pipe 303. Then, two fixing brackets 201 are installed on both sides of one end of the outer wall of the wastewater treatment tank 1, so that the two fixing brackets 201 can clamp and fix the inlet pipe 301. Then, fastening bolts 202 are used to penetrate the inner wall of the fixing brackets 201 and are threadedly connected to the inner wall of the wastewater treatment tank 1, so that the stirring mechanism 3 can be stably fixed inside and outside the wastewater treatment tank 1.

[0034] The treated wastewater is then transported to wastewater treatment tank 1 through pipelines. The water pump 302 is activated by the control terminal, which then transports clean water through the inlet pipe 301 to the outlet pipe 303. The clean water is then transported to the nozzles 305 through two connecting pipes 304. The two nozzles 305, which are diagonally arranged and have parallel water outlet directions, allow high-pressure water to be sprayed along the inner walls of both ends of the wastewater treatment tank 1. This causes the wastewater inside the wastewater treatment tank 1 to rotate and form a swirling flow, thus ensuring that the liquid inside the wastewater treatment tank 1 is fully mixed and uniform. At the same time, it can prevent the precipitation of suspended solids in the tank, thereby ensuring the wastewater treatment effect of the anoxic tank. This embodiment specifically solves the problem in the prior art that the liquid inside the anoxic tank cannot be fully mixed and that suspended solids are prone to precipitation, resulting in poor wastewater treatment effect.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
