Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to an intelligent dosing device. Background Technology

[0002] Intelligent dosing devices for wastewater treatment are advanced equipment that integrates automated control, intelligent monitoring, and precise dosing functions. They aim to optimize the addition of chemical agents in the wastewater treatment process through intelligent technology, thereby improving treatment efficiency, reducing operating costs, and minimizing manual intervention.

[0003] This intelligent dosing device primarily monitors water quality parameters in real time using sensors and controls pumps and valves via algorithm models to input chemicals from the storage tank into the wastewater pool. While this improves operational efficiency, the large overall volume of the wastewater pool makes it difficult for the intelligently input chemicals to spread throughout the entire pool in a short time. This significantly reduces the mixing efficiency between the chemicals and the wastewater. Furthermore, the slow-spreading chemicals can affect the sensing of normal water quality parameters, severely impacting the overall operational efficiency and accuracy of the intelligent dosing device. Utility Model Content

[0004] This application proposes an intelligent dosing device, which features a uniformly distributed liquid distribution pipe that covers a larger area on a plane for large-area dosing, and a vertically moving liquid distribution pipe that covers an even larger area in a three-dimensional direction. The movement of the liquid distribution pipe compresses the liquid to surge from the gaps, improving mixing efficiency. The surging liquid passes through a stirring device for diversion and mixing, further improving mixing efficiency. This invention addresses the problems of existing intelligent dosing devices, such as small dosing range, slow agent release, and low agent-sewage mixing efficiency.

[0005] To achieve the above objectives, this application adopts the following technical solution: an intelligent dosing device, comprising a hydraulic cylinder, a hydraulic rod disposed inside the hydraulic cylinder, a transmission pipe disposed at the bottom end of the hydraulic rod for providing power for reciprocating up and down motion; a diversion pipe disposed at the bottom of the transmission pipe, and evenly distributed liquid distribution pipes disposed in the axial direction of the diversion pipes, with evenly distributed injection nozzles disposed at the bottom of the liquid distribution pipes in the axial direction for covering a larger dosing area; evenly distributed mounting frames disposed between adjacent liquid distribution pipes; and an agitator disposed on the mounting frames.

[0006] Preferably, an infusion hose is provided on one side of the transmission tube, which is used to deliver the medicine without affecting the reciprocating motion of the transmission tube.

[0007] Preferably, the mounting bracket includes a central positioning ring and connecting rods on both sides of the positioning ring.

[0008] Preferably, the end of the connecting rod away from the positioning ring is connected to the side wall of the nearby liquid distribution pipe to fix the position of the positioning frame and move synchronously with the liquid distribution pipe.

[0009] Preferably, the agitation device includes a central shaft disposed within a positioning ring, and inclined blades I and II evenly distributed at the top and bottom of the central shaft, respectively.

[0010] Preferably, two symmetrical limiting rings are provided in the middle of the central shaft, and the opposite surfaces of the two limiting rings are respectively attached to the top and bottom ends of the positioning ring.

[0011] Preferably, the inclined blades I and II are inclined in opposite directions to guide the passing liquid flow in the opposite direction.

[0012] Preferably, the central shaft has a hollow hole extending through the shaft from top to bottom, which is used to form a multi-directional laminar flow for the passing liquid.

[0013] The present application provides an intelligent dosing device that, by setting up evenly distributed liquid distribution pipes, allows the spray nozzles on the liquid distribution pipes to cover a larger area, thereby enabling the dosing agent to be injected into a larger area of ​​the sewage tank from numerous spray nozzles, thus increasing the contact area between the agent and the sewage per unit time and improving the dosing efficiency.

[0014] At the same time, the hydraulic rod drives the liquid distribution pipe to move up and down, causing the position of the spray nozzle to change continuously in the height direction. This allows the agent sprayed from the nozzle to be directly sprayed into the longitudinal direction of the sewage tank over a large area, fully covering the sewage in the tank for efficient dosing.

[0015] Simultaneously, the up-and-down movement of the distribution pipes causes the evenly distributed pipes to compress the sewage below as they move downwards. This causes the compressed sewage to surge upwards through the space between adjacent distribution pipes. At this time, most of the agent sprayed from the lower nozzle will also surge upwards along with the upward-flowing sewage under the compression, allowing the surging sewage and agent to mix as they pass through the space between adjacent distribution pipes. Conversely, as the evenly distributed distribution pipes move upwards, they compress the sewage above, causing the compressed sewage to surge downwards through the space between adjacent distribution pipes. Most of the agent sprayed from the lower nozzle will be pushed downwards by the surging sewage, resulting in the surging sewage pushing the agent below for contact mixing, thus improving the mixing efficiency of the agent and sewage.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] Example 1 Please see Figures 1 to 2 A smart dosing device includes a hydraulic cylinder 1, a hydraulic rod 2 movably sleeved inside the hydraulic cylinder 1, and a transmission pipe 3 bolted to the bottom end of the hydraulic rod 2, so that the hydraulic cylinder 1 can drive the transmission pipe 3 to move up and down through the hydraulic rod 2, thereby injecting the agent into the sewage tank in a three-dimensional and large-scale manner. An infusion hose 31 is fixedly connected to one side of the transmission pipe 3, so that the agent can be injected into the transmission pipe 3 through the infusion hose 31, and the infusion hose 31 does not affect the normal movement of the transmission pipe 3 when the transmission pipe 3 is moving up and down.

[0021] See Figures 1 to 2 A diversion pipe 4 is fixedly connected to the bottom of the transmission pipe 3. A distribution pipe 5 is fixedly connected to both sides symmetrically in the axial direction of the diversion pipe 4, so that the agent in the transmission pipe 3 can be diverted to the distribution pipe 5 through the diversion pipe 4, thereby expanding the area where the agent is dispersed. A uniformly distributed spray nozzle 51 is fixedly connected to the bottom of the distribution pipe 5 in the axial direction, so that the numerous spray nozzles 51 can inject the agent into a larger area of ​​the sewage tank, thereby increasing the contact area between the agent and the sewage per unit time and improving the dosing efficiency.

[0022] The transmission pipe 3 drives the liquid distribution pipe 5 to move up and down reciprocally, so that the position of the spray nozzle 51 changes continuously in the height direction. This allows the agent sprayed from the spray nozzle 51 to be sprayed directly onto the longitudinal direction of the sewage tank over a large area, fully covering the sewage in the sewage tank for efficient dosing.

[0023] Simultaneously, the up-and-down movement of the distribution pipes 5 causes the evenly distributed distribution pipes 5 to squeeze the sewage below when moving downwards, causing the squeezed sewage to surge upwards from the space between adjacent distribution pipes 5. At this time, most of the agent sprayed from the lower nozzle 51 will also surge upwards with the upward-flowing sewage under the pressure, so that the surging sewage and agent mix as they pass through the space between adjacent distribution pipes 5. When the evenly distributed distribution pipes 5 move upwards, they can squeeze the sewage above, causing the squeezed sewage to surge downwards from the space between adjacent distribution pipes 5. Most of the agent sprayed from the lower nozzle 51 will be pushed downwards by the surging sewage, causing the surging sewage to push the agent below for contact mixing, thereby improving the mixing efficiency of the agent and sewage.

[0024] Example 2 Please see Figure 1 , Figure 3 Based on Example 1, evenly distributed mounting brackets are fixedly connected between adjacent liquid distribution pipes 5.

[0025] See Figure 1 , Figures 3 to 4 The mounting frame includes a central positioning ring 6 and connecting rods 61 fixed on both sides of the positioning ring 6. The end of the connecting rod 61 away from the positioning ring 6 is fixedly connected to the side wall of the liquid distribution pipe 5. The position of the positioning ring 6 is restricted by the connecting rod 61, so that the liquid distribution pipe 5 can drive the mounting frame to move synchronously when it moves up and down.

[0026] The mounting frame is equipped with an agitator.

[0027] read Figure 1 , Figures 3 to 5 The agitation device includes a central shaft 7 movably sleeved inside a positioning ring 6. Two symmetrical limiting rings 71 are fixedly sleeved in the middle of the central shaft 7. The opposing surfaces of the two limiting rings 71 are respectively attached to the top and bottom ends of the positioning ring 6. This allows the central shaft 7 to rotate within the positioning ring 6, while also preventing axial displacement of the central shaft 7 through contact with the positioning ring 6 via the two limiting rings 71. At the same time, when the positioning ring 6 moves up and down reciprocating with the liquid distribution pipe 5, it can also drive the central shaft 7 to move in the same direction.

[0028] read Figure 1 , Figures 3 to 5 The top of the central shaft 7 is fixedly fitted with evenly distributed inclined blades I8, and the bottom of the central shaft 7 is fixedly fitted with evenly distributed inclined blades II81.

[0029] read Figure 1 , Figures 3 to 5 The inclined blades I8 and II81 are inclined in opposite directions, so that when the sewage and the agent surge upward or downward between the distribution pipe 5, the liquid flow can impact the inclined blades I8 or II81, thereby driving the entire agitator to rotate. When the agitator rotates, it agitates the surging liquid flow, further improving the mixing efficiency of sewage and agent.

[0030] It should be noted that the liquid flow passing through a single agitator is mainly bidirectional spiral surging under the guidance of the inclined blades I8 and II81 in different directions. Taking the upward surge of the liquid flow as an example, the upward surge of the liquid flow will impact the inclined blade II81 below. Since the inclined blade II81 is mainly inclined downward, the liquid flow passing through it will push the inclined blade II81, causing the central shaft 7 to rotate. This causes the liquid flow passing through the inclined blade II81 to turn to one side. The inclined blade I8 above has a different inclination direction, causing the blades passing through the inclined blade I8 to turn to the other side. This multidirectional change of the liquid flow improves the mixing efficiency.

[0031] At the same time, the liquid flow passing between adjacent agitators will also undergo a turning motion due to the influence of the turning liquid flow on both sides.

[0032] Example 3 Please see Figure 5 Based on Embodiment 2, the central shaft 7 has a hollow hole 9 that runs vertically through the shaft, so that some of the upward or downward liquid flow will directly pass through the hollow hole 9 and is less likely to be guided by the inclined blades I 8 and II 81. This part of the liquid flow that directly passes through will come into contact with the liquid flow after turning at the center again, thereby forming laminar flow from the inside out, further enhancing the mixing effect.
