Description

Technical Field

[0001] The present application relates to the technical field of raw water treatment, and in particular to a raw water treatment tank. Background Art

[0002] During the raw water treatment process, chemicals are often added to effectively regulate the water quality. First, raw water is drawn from a sedimentation tank, passed through a filter for preliminary impurity removal, and then enters a raw water treatment tank. Chemicals are then added to the treatment tank to regulate the water quality. To ensure the chemicals are evenly distributed throughout the raw water, they are thoroughly mixed using a stirring device. However, the chemical reaction and stirring process inevitably produces a large amount of foam, which quickly accumulates on the surface of the treatment tank.

[0003] Because the presence of foam can negatively impact subsequent treatment steps, it is necessary to wait until the foam volume is controlled to a certain level before proceeding to the next step of treatment. This process of waiting for the foam to subside significantly reduces the efficiency of raw water treatment, prolongs treatment time, and increases treatment costs. Utility Model Content

[0004] The purpose of this application is to provide a raw water treatment tank to solve the problem of large amounts of foam generated during the raw water treatment process.

[0005] A raw water treatment tank provided in the present application adopts the following technical solution: it includes a box body, a stirring pump, a first pipe connected to the box body and the stirring pump respectively, and a spray mechanism arranged at the top of the box body, the stirring pump is connected to the spray mechanism, the first pipe is provided with a dosing pipe for an external dosing device, the raw water in the box body is first transported to the first pipe by the stirring pump, and chemical agents are added to the raw water in the first pipe through the dosing pipe, the stirring pump transports the raw water with added chemicals in the first pipe back to the box body, and part of the raw water is transported to the spray mechanism under the action of the stirring pump, and then transported back to the box body through the spray mechanism.

[0006] By adopting the above technical solution, the first pipeline, the stirring pump and the box body constitute a raw water circulation transportation and stirring system. Chemical agents are added to the first pipeline, and the raw water is circulated, transported and stirred to make the chemicals more evenly diffused in the box body. A large amount of foam will be produced during the raw water treatment process. Part of the raw water is transported into the spray mechanism, and the foam generated is punctured by the spray mechanism.

[0007] Optionally, the box body is provided with a first interface and a second interface, there is a height difference between the first interface and the second interface, the first interface is connected to the input end of the stirring pump through the first pipe, and the second interface is connected to the output end of the stirring pump.

[0008] By adopting the above technical solution, due to the height difference between the two interfaces and the connection method with the stirring pump, when the stirring pump is operating, the raw water in the tank can be sucked into the stirring pump from the first interface at the lower position. After the stirring pump is activated, it returns to the tank through the second interface at the higher position. This forms a circular flow path, which is conducive to the thorough mixing of raw water and chemicals and their uniform distribution throughout the treatment system. The circular flow allows the raw water to continuously add chemicals through the dosing pipe and be thoroughly mixed by the stirring pump. At the same time, this flow pattern also helps to quickly disperse the treated raw water to various parts of the tank, avoiding localized excessive concentration or uneven treatment, thereby improving the effectiveness of raw water treatment.

[0009] Optionally, the box is connected to a water inlet pipe, and the water inlet pipe is provided with a filter.

[0010] By adopting the above technical solution, the setting of the water pipeline ensures that the raw water can flow into the treatment tank stably and continuously, providing water source for the subsequent treatment process. The preliminary filtration through the filter can effectively reduce the impurities entering the box and subsequent treatment equipment, reduce the risk of equipment wear and blockage, and extend the service life of the equipment.

[0011] Optionally, the box is connected to a water outlet pipe, and the water outlet pipe is connected to a transport pump.

[0012] By adopting the above technical solution, the setting of the water outlet pipe ensures that the treated water can be discharged from the treatment tank in an orderly manner for subsequent use or further processing. The transport pump can overcome factors such as pipeline resistance and height difference and smoothly transport the water to the required location.

[0013] Optionally, the box is rotatably connected to a rotating shaft, the rotating shaft is fixedly connected to an impeller, and the central axis of the second interface and the axis of the rotating shaft are skew lines.

[0014] By adopting this technical solution, the impeller stirs the raw water in the tank, promoting mixing between the raw water and the chemical and improving the treatment effect. Furthermore, as a power input, it converts the impact force of the raw water at the second interface into rotational force for the shaft. The central axis of the second interface and the axis of the shaft are skewed, allowing the water flowing from the second interface to impact the impeller. This impact force is converted into rotational power for the impeller, thus enabling the shaft to rotate without the need for an additional power source.

[0015] Optionally, the box body is fixedly connected to an annular rack, which is arranged along the inner wall of the box body. The rotating shaft is rotatably connected to a first roller and a second roller. The end of the first roller is fixedly connected to a first tooth that meshes with the annular gear. The first roller and the second roller are connected through a gear. The first roller and the second roller rotate in opposite directions, and the surface of the first roller abuts against the surface of the second roller.

[0016] By adopting the above technical solution, the arrangement of the annular rack enables the first roller to move in a circular motion along the inner wall of the box under the drive of the rotating shaft. The first roller meshes with the annular rack through the first tooth at the end. When the rotating shaft rotates, the first roller begins to rotate under the action of the annular rack. Due to the meshing relationship with the annular rack, the rotation direction of the first roller is related to the rotation direction of the rotating shaft, and stable power can be obtained. The first roller and the second roller are connected by gears, so that the rotation of the first roller can be transmitted to the second roller. Due to the characteristics of the gear connection, the rotation directions of the first roller and the second roller are opposite. The first roller and the second roller are set on the surface of the raw water. On the one hand, the first roller and the second roller rotate around the rotating shaft to clear the foam on the surface. On the other hand, the opposite rotation directions of the first roller and the second roller can break the foam.

[0017] Optionally, the spraying mechanism includes a turntable and several nozzles installed on the turntable. The turntable is fixedly connected to the rotating shaft, and the rotating shaft passes through the center of the turntable. The rotating shaft is provided with a first channel connected to the inside of the turntable, and the first channel is provided with a second pipe connected to the stirring pump.

[0018] By adopting the above technical solution, the turntable rotates along with the rotating shaft, so that the spraying range of a single nozzle becomes larger, thereby increasing the defoaming efficiency.

[0019] Optionally, a connecting channel is provided at the top of the box body, the second pipe is connected to the connecting channel, the connecting channel is connected to the first channel, the box body is provided with a support frame, the support frame is rotatably connected to the rotating shaft, and the first channel and the connecting channel are movably sealed.

[0020] By adopting the above technical solution, the first channel realizes movable docking with the second pipeline, and the support frame supports the rotating shaft.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. Multi-faceted foam removal: On the one hand, the spray mechanism punctures the generated foam; on the other hand, the rotating shaft in the box drives the impeller to stir the raw water. The water flow from the second interface impacts the impeller, driving the rotating shaft without an additional power source. At the same time, the first and second rollers on the rotating shaft not only skim off the surface foam but also break it up. These measures work together to effectively eliminate foam, provide better conditions for subsequent treatment steps, and further enhance the raw water treatment effect.

[0023] 2. The raw water circulation, transportation and stirring system composed of the first pipeline, stirring pump and box body enables the chemical agents to be more evenly diffused in the box body, ensuring that the chemical agents are fully mixed with the raw water and improving the effect of water quality regulation.

[0028] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0029] The embodiment of the present application discloses a raw water treatment tank.

[0030] Example 1, with reference to Figure 1 and Figure 2A raw water treatment tank includes a box body 1, a stirring pump 2, a first pipe 3 respectively connected to the box body 1 and the stirring pump 2, and a spray mechanism 4 arranged at the top of the box body 1. The box body 1 is provided with two interfaces of different heights, namely a first interface 31 and a second interface 32. The first interface 31 is connected to the input end of the stirring pump 2 through the first pipe 3, and the second interface 32 is connected to the output end of the stirring pump 2. In this embodiment. The second interface 32 is located at the bottom end of the box body 1, so that the raw water in the box body 1 flows from the bottom end of the box body 1 into the stirring pump 2 through the first pipe 3, and then flows back to the upper layer of the raw water from the output end of the stirring pump 2 through the first pipe 3, so that the raw water in the box body 1 circulates. The first pipe 3 is provided with a dosing pipe 5 of an external dosing device, and the treated chemical agent is added to the circulating flow of the raw water, so that it can be better diffused into the raw water. The stirring pump 2 is connected to the spray mechanism 4. When the substances in the raw water react with the chemical agent, a large amount of foam will be generated, which will gather on the surface of the raw water. Part of the raw water will be transported to the spray mechanism 4, and the foam covering the surface will be punctured by spraying.

[0031] refer to Figure 1 The box body 1 is connected with an inlet pipe 6 and an outlet pipe 7. The inlet pipe 6 is installed with a filter 61. The outlet pipe 7 is connected to a transport pump 71. The inlet pipe 6 is connected to the sedimentation tank. The upper layer of raw water in the sedimentation tank is transported to the box body 1 through the inlet pipe 6. During the transportation process, it needs to pass through the filter 61 to filter and remove fine particles in the raw water. After the raw water in the box body 1 is treated, it is transported to the next process through the outlet pipe 7 and the transport pump 71.

[0032] Example 2: This example differs from Example 1 in that a mechanical defoaming device is added, and the spray mechanism 4 is rotatable. Specifically, it includes a rotating shaft 11 rotatably connected to the housing 1, and an impeller 12 fixedly connected to the rotating shaft 11. The impeller 12 is arranged at the bottom of the housing 1. When the circulating raw water flows out from the second interface 32, the water flow has a relatively strong impact, and the raw water will impact the impeller 12, thereby driving the impeller 12 to rotate. The impeller 12 has two functions. On the one hand, it stirs the raw water in the housing 1 to make the medicine mixing more uniform; on the other hand, it converts the water flow impact of the second interface 32 into the rotation of the rotating shaft 11. The rotating shaft 11 is fixedly connected to a mounting block, and the mounting block is rotatably connected to the first roller 81 and the second roller 82. A roller 81 and a second roller 82 are suspended horizontally on the mounting block. The housing 1 is fixedly connected to a ring gear 8 that is distributed along the inner wall of the housing. The end of the first roller 81 is fixedly connected to a first tooth 83 that meshes with the ring gear 8. The first roller 81 and the second roller 82 are connected by a gear transmission. The surface of the first roller 81 abuts the surface of the second roller 82. In this way, the first roller 81 and the second roller 82 can rotate within the housing 1 under the action of the first tooth 83 and the ring gear 8. The first roller 81 can rotate radially under the action of the first tooth 83 and the ring gear 8, and the first roller 81 and the second roller 82 rotate in opposite directions through the gear transmission. The first roller 81 and the second roller 82 are used to break the foam on the surface of the raw water; the circumferential rotation of the first roller 81 and the second roller 82 can scrape and gather the surface foam to one side, and the radial rotation of the first roller 81 and the second roller 82 can break the foam.

[0033] refer to Figure 2 and Figure 3 The spray mechanism 4 includes a turntable 41 and a plurality of nozzles 42 mounted on the turntable 41. The turntable 41 is fixedly connected to the rotating shaft 11, which extends through the center of the turntable 41. The rotating shaft 11 is provided with a first channel 111 connected to the interior of the turntable 41. The first channel 111 is provided with a second pipe 14 connected to the stirring pump 2. A connecting channel 13 is provided at the top of the housing 1. The second pipe 14 is connected to the connecting channel 13, and the connecting channel 13 is connected to the first channel 111. The housing 1 is provided with a support frame 43, which is rotatably connected to the rotating shaft 11. The first channel 111 and the connecting channel 13 are movably sealed. The stirring pump 2 transports liquid to the connecting channel 13 at the top of the housing 1 through the second pipe 14. The liquid in the connecting channel 13 then enters the interior of the turntable 41 through the first channel 111. Due to the movable seal between the first channel 111 and the connecting channel 13, it can ensure smooth liquid transportation and prevent liquid leakage. As the rotating shaft 11 rotates, the rotating disk 41 is driven to rotate, and the nozzles 42 installed on the rotating disk 41 spray the liquid evenly.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
