Description

Technical Field

[0001] The present invention relates to the technical field of new pollutant removal from river water bodies, and specifically to a device and method for accurately and quantitatively removing new pollutants from river water bodies. Background Art

[0002] There are many types of new pollutants in river water, including endocrine disruptors, pharmaceuticals and personal care products, nanomaterials, perfluorinated organic compounds, brominated flame retardants, antibiotic resistance genes, etc. Although these new pollutants exist in low concentrations in the environment, they can have a great negative impact on ecology and human health.

[0003] There are many ways to remove these new pollutants, the most common ones are the removal method using removers and physical methods. Among them, the removal method using removers is to remove pollutants by adding removers into the river, such as activated carbon adsorbents and flocculants. This method is widely used due to its advantages such as high efficiency, flexibility and controllability. At present, when in use, the corresponding removers are usually added into the river for the new pollutants in the river, and the dosage of the removers is usually manually adjusted by experience. This method has low accuracy in the dosage of the removers. If the remover is added in excess, it will lead to unnecessary waste and may even cause secondary pollution. If the remover is added too little, it will affect the removal effect of new pollutants in the river water. For this reason, we propose a device and method for precise quantitative removal of new pollutants in river water. Summary of the invention

[0043] A liquid storage tank 5 is provided on the top of the floating member 1 for containing the incoming remover or the liquid for mixing with the remover.

[0045] Wherein, the quantitative batching mechanism 6 comprises:

[0046] The removal agent placement tank 61 is used to store removal agents for treating new pollutants, such as flocculants, activated carbon adsorbents, and biological agents;

[0047] The metering cylinder 62 is connected to the liquid outlet of the removal agent placement tank 61 through a feed pipe, a solenoid valve 1 66 is provided in the feed pipe, the discharge end of the metering cylinder 62 is connected to the inner cavity of the liquid storage tank 5, and a solenoid valve 2 67 is provided in the discharge end of the metering cylinder 62; and,

[0048] The floating plate 63 is movably arranged in the quantitative cylinder 62. The floating plate 63 moves in the quantitative cylinder 62 as the liquid in the quantitative cylinder 62 enters. A plurality of through holes are formed on the floating plate 63. A limit block 64 is arranged above the floating plate 63. The limit block 64 is connected to the inner wall of the top of the quantitative cylinder 62 by adjusting the telescopic rod 65. A contact sensor 68 is arranged at the bottom of the limit block 64. The adjustable telescopic rod 65 is an electric telescopic rod. The position of the limit block 64 can be adjusted by adjusting the telescopic rod 65, so as to control the removal amount entering the liquid storage tank 5. The quantitative cylinder 62 can be made of a transparent material, and a capacity scale can be set on its surface wall for the user to adjust. Furthermore, from the attached Figure 1 It can be seen that the dosing cylinder 62 is in the liquid storage tank 5. A transparent window is provided on the outer wall of the liquid storage tank 5 at a position corresponding to the dosing cylinder 62, so that the user can observe the capacity scale on the outer wall of the dosing cylinder 62 from the outside. In order to ensure the stable movement of the floating plate 63 and the limit block 64, a vertical guide rod that passes through the floating plate 63 and the limit block 64 can also be provided in the dosing cylinder 62.

[0049] It should be noted that for different removers, users can choose to use them directly or inject liquid into the liquid storage tank 5 first according to the usage situation, so that the remover is mixed with the liquid before use;

[0050] The contact sensor 68 is electrically connected to the control electrical device 4 arranged on the floating member 1, and is used to control the control electrical device 4 to control the solenoid valve 2 67 to open and the solenoid valve 1 66 to close when it contacts the floating plate 63. In this way, quantitative dosing is achieved to avoid excessive or insufficient input of the required removal agent, thereby ensuring the quality of removal of new pollutants in the river water while avoiding waste of the removal agent.

[0051] As a preference, the bottom of the floating member 1 of this embodiment is connected to a water body detection device 3 through a connecting frame 2, and the water body detection device 3 is electrically connected to a control electrical device 4.

When in use, the wireless communication device can remotely send the water body data detected by the water body detection device 3 to the user's terminal (such as a computer device, etc.), and the user can analyze the water body data to determine the required remover, and then send a control signal to the wireless communication device through the terminal, so that the controller controls the corresponding quantitative batching mechanism 6, drainage device 8 and other electrical appliances to work to put the remover into the work;

[0053] The power supply device is, for example, a battery.

[0054] Please see attached Figure 3 -Attached Figure 5

[0055] Preferably, the spraying treatment mechanism 7 of this embodiment includes:

[0056] The rotating shaft 71 is rotatably inserted at one end of the top of the floating member 1. A bearing is provided at the connection between the rotating shaft 71 and the floating member 1. The bottom of the rotating shaft 71 extends below the floating member 1 and is connected to the spraying pipe 72. The spraying pipe 72 is perpendicular to the rotating shaft 71. The liquid inlet end of the spraying pipe 72 is connected to the spraying pipeline.

[0057] The impeller member 73 includes a shaft and an impeller sleeved on the outer wall of the shaft. The impeller member 73 is rotatably arranged at one end of the floating member 1. The axis of the shaft of the impeller member 73 is parallel to the width direction of the floating member 1. When the floating member 1 moves, it is driven to rotate by the river water. One end of the shaft of the impeller member 73 extends to a protective shell fixed to the side wall of the floating member 1. The outer wall portion of the shaft located in the protective shell is sleeved with a toothless gear 74. The toothless gear 74 is meshed with a rack 75. The rack 75 horizontally penetrates the protective shell, and one end of the rack 75 is connected to the side wall of the protective shell through an elastic member, such as a spring; and,

[0058] The second rack 76 is horizontally arranged above the floating member 1 and meshes with a driven gear fixedly sleeved on the outer wall of the rotating shaft 71. The second rack 76 is connected to the first rack 75 through a bracket, and the bracket is L-shaped.

[0059] When the floating member 1 moves, the impeller member 73 rotates, and its shaft drives the toothless gear 74. The toothless gear 74 drives the rack 2 76 to move synchronously through the rack 1 75 and the bracket. The rack 2 76 drives the driven gear to drive the rotating shaft 71. When the toothless gear 74 is separated from the rack 1 75, the rack 1 75 is reset under the action of the elastic member. In this way, the rotating shaft 71 drives the spraying pipe 72, so that one end of the spraying pipe 72 swings back and forth, thereby increasing the spraying range. The spraying pipe 72 plays a role in stirring the river water, so that the sprayed removal agent is evenly mixed with the water of the river, thereby improving the removal quality of new pollution in the river water.

[0060] Preferably, the spraying treatment mechanism 7 of this embodiment further includes:

[0061] A spray head is connected to the liquid outlet end of the spray pipe 72, and the diameter of the spray head is larger than the diameter of the spray pipe 72;

[0062] There are two groups of sealing plates 77, which are symmetrically inserted into the outer wall of the liquid outlet end of the spray head. One end of the sealing plate 77 located in the spray head is connected to the inner wall of the spray head through an elastic member. The height of the sealing plate 77 is less than the inner cavity radius of the spray head, so that when the two groups of sealing plates 77 are in the initial position, there is still a certain distance between them, so that the remover can be sprayed normally. The two groups of sealing plates 77 are connected to the opposite sides with a pull rope 78. The other end of the pull rope 78 bypasses the guide member provided on the outer wall of the liquid outlet end of the spray head and then moves through the outer wall of the spray head and is connected to the movable frame 79. The guide member, for example, includes a bracket connected to the outer wall of the liquid outlet end of the spray head and a roller provided at the end of the bracket away from the outer wall of the liquid outlet end of the spray head, so that the pull rope 78 pulls the two groups of sealing plates 77 away from each other. The movable frame 79 is movably provided in the spray head; and,

[0063] The second pull rope 710 has one end connected to the movable frame 79, and the other end passes through the outer wall of the top of the spray pipe 72 and the top of the rotating shaft 71 in sequence and is connected to the movable cylinder 711. The movable cylinder 711 is slidably sleeved on the top of the outer wall of the rotating shaft 71. The movable cylinder 711 can use the slider on its inner wall to cooperate with the vertical slide groove opened on the top of the outer wall of the rotating shaft 71, so that the movable cylinder 711 can move up and down relative to the rotating shaft 71 and the two can rotate synchronously. The outer wall of the movable cylinder 711 is provided with a movable frame through a bearing rotation sleeve. One end of the movable frame is slidably connected to the guide frame 713. The guide frame 713 is arranged on the floating member 1. The movable frame is connected to a driving part through the pull rope three 712. The driving part is used to drive the pull rope three 712 to drive the movable frame to move. The movable frame is connected to the floating member 1 through an elastic member to drive the movable frame to reset.

[0064] When in use, the driving unit is controlled to reel in the pull rope three 712, so that the movable frame moves upward, the movable frame drives the movable cylinder 711, the movable cylinder 711 pulls the movable frame 79 through the pull rope two 710, and the movable frame 79 pulls the two sealing plates 77 away from each other through the pull rope one 78, thereby increasing the distance between the two sealing plates 77, thereby adjusting the spraying amount;

[0065] A guide roller structure for guiding the pull rope may be provided at the spray pipe 72, the guide frame 713 and other positions, which will not be described in detail herein.

[0066] Example 1

[0067] Please see attached Figure 6

[0068] Preferably, the driving unit of this embodiment includes:

[0069] The outer shell 714 is connected to the floating member 1 and is movably sleeved on the outer side of the shaft of the impeller member 73. The outer wall of the shaft in the outer shell 714 is sleeved with an assembly roller 715. The outer wall of the assembly roller 715 is provided with a plurality of groups of elastic telescopic rods 716 in a circular array. The end of the elastic telescopic rod 716 away from the assembly roller 715 is rotatably provided with a roller. The assembly roller 715 rotates with the shaft of the impeller member 73. Under the action of centrifugal force, the elastic telescopic rod 716 is extended; and,

[0070] The movable plate 717 is movably disposed in the housing 714 and is located above the assembly roller 715. The bottom of the movable plate 717 is in sliding contact with the roller, and the movable plate 717 is connected to an end of the pull rope 712 away from the movable frame.

[0071] When the floating member 1 driven by the device that can move on the water surface reaches a preset threshold value, the elastic telescopic rod 716 moves outward under the action of centrifugal force, thereby pushing the moving plate 717 upward to a preset position, so that the moving plate 717 pulls the moving frame upward through the pull rope 3 712;

[0072] It should be noted that the centrifugal force of rotation in this state is greater than the sum of the weight of the elastic telescopic rod 716, the elastic member connected to the sealing plate 77, the elastic member connected to the movable frame, and the movable plate 717, so that the elastic telescopic rod 716 can push the movable plate 717 upward under the action of the centrifugal force without shrinking;

[0073] This method controls the moving speed of the device that can move on the water surface in the river, thereby changing the shaft rotation speed of the impeller member 73, so that the size of the liquid outlet end of the spray head can be adjusted, thereby achieving adjustment of the spraying amount.

[0074] Example 2

[0075] Preferably, the driving unit of this embodiment includes:

[0076] A speed detection device (not shown in the figure), which is a conventional device in the art and will not be described in detail here, is provided on the floating member 1 and is used to detect the shaft speed of the impeller member 73. The speed detection device is electrically connected to the control electrical member 4; and,

[0077] The winding device (not shown in the figure) includes, for example, a servo motor and a winding roller, which is arranged on the guide frame 713, and its winding rope three 712 is away from one end of the movable frame, and is used for driving the winding rope three 712 by the control electrical device 4 when the speed detection device detects that the shaft speed of the impeller member 73 reaches a preset threshold.

[0078] This method can also control the moving speed of the device that can move on the water surface in the river, thereby changing the shaft rotation speed of the impeller member 73, so as to adjust the size of the liquid outlet end of the spray head, thereby achieving adjustment of the spraying amount.

[0079] A method for accurately and quantitatively removing new pollutants from river water, using the above-mentioned removal device, comprises the following steps:

[0080] S1: When in use, the floating member 1 is connected to a device that can move on the water surface, and the floating member 1 is driven to a designated area of ​​the river by the device that can move on the water surface;

[0081] S2: By adjusting the telescopic rod 65 to control the position of the limit block 64 in the quantitative cylinder 62, the electromagnetic valve 1 66 at the corresponding remover placement tank 61 is then opened, so that the required remover enters the corresponding quantitative cylinder 62, and the floating plate 63 in the quantitative cylinder 62 moves upward with the entering remover. When the floating plate 63 contacts the contact sensor 68, the contact sensor 68 sends a signal to the control electrical device 4, and the control electrical device 4 controls the electromagnetic valve 2 67 to open and the electromagnetic valve 1 66 to close, so that the required remover enters the liquid storage tank 5 in a quantitative manner;

[0082] S3: After step S2, the drainage device 8 is turned on, and the floating member 1 is driven to move by the device moving on the water surface. When the floating member 1 moves, the remover is sprayed into the water through the spraying treatment mechanism 7 to treat new pollutants in the river water.

[0083] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
