Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment and recycling dosing device for a waterworks. Background Art

[0002] Tap water is drinking water produced by professional equipment through multiple complex process flows and then delivered to various users. At present, there are generally two sources of tap water. One is to extract groundwater from drilling wells, and the other is to take surface water from reservoirs, rivers, and lakes. Tap water refers to water that meets the corresponding standards for people's living and production use that is produced after purification and disinfection by a water treatment plant. Domestic water is mainly drawn from rivers, lakes, and groundwater through the water plant's water intake pump station. Surface water, whether groundwater or surface water, needs to go through multiple processes such as sedimentation, decontamination, and disinfection after entering the water plant. The sewage treatment of the water plant is the process of cleaning and treating water containing wastewater, sewage and other pollutants. By adding heavy metal capture agents, flocculants, lime powder and other agents, harmful pollutants and microorganisms are removed from sewage to minimize the impact of sewage in the environment.

[0003] For example, the patent announcement number CN219730642U is a flocculation sedimentation tank with a movable flocculant delivery. By installing a storage box on a movable frame, when the flocculant is delivered, the movable frame is driven to move along the top of the tank body to evenly deliver the flocculant inside. During the movement, the stirring component is simultaneously driven to rotate to stir the sewage in the tank body, so that the delivered flocculant is in full contact with the sewage. This method is suitable for the flocculant delivery work in large-volume flocculation sedimentation tanks and improves the efficiency of rapid and full contact between the flocculant and the sewage.

They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0033] Furthermore, it should be understood that for the sake of ease of description, the sizes of the various components shown in the drawings are not drawn according to actual proportions. For example, the thickness or width of certain layers may be exaggerated relative to other layers.

[0034] It should be noted that like reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined or described in one drawing, it will not need to be further discussed and described in detail in the description of the subsequent drawings.

[0035] In order to solve the technical problems raised by the background technology, the present application proposes a sewage treatment and reuse dosing device for a water plant. Specifically, the sewage treatment and reuse device includes a sewage pool 1, such as Figure 1 and Figure 2 As shown, a sewage inlet pipe 101 is installed on the outer side of one end of the sewage pool 1, and a partition 102 is installed between the inner sides of the sewage pool 1. The partition 102 divides the sewage pool 1 into two impurity removal areas and a dosing chamber. A water outlet pipe 103 is installed on one side of the partition 102. The water outlet pipe 103 is located in the dosing chamber. The sewage discharge structure 2 is arranged on the inner side of the sewage pool 1 for discharging sewage. The impurity removal structure 3 is arranged in the impurity removal area for removing impurities in the sewage in the impurity removal area. The sewage discharge structure 2 includes a partition plate 201, which is arranged between the inner sides of the sewage pool 1, and a movable groove 206 is opened on the top and both sides of the partition plate 201. A sewage discharge gate 202 is movably arranged in the movable groove 206. The sewage discharge gate 202 A threaded hole is provided at the center of the sewage pool 1, and a threaded rod 204 is threadedly connected in the threaded hole. A support frame 203 is installed at the top of the sewage pool 1, and the support frame 203 is located above the isolation plate 201. A motor 205 is installed at the top of the support frame 203, and the output end of the motor 205 is connected to the top of the threaded rod 204. The partition 102 is connected at the center of the isolation plate 201, and the isolation plate 201 is a T-shaped structure. The impurity removal structure 3 includes a impurity removal frame 301, which is located in the impurity removal area. A conveyor belt 302 is movably provided in the impurity removal frame 301, and an impurity receiving box 303 is movably provided at the top of the sewage pool 1. The impurity receiving box 303 is located below the top of the impurity removal frame 301 and is used to receive impurities in the sewage.

[0036] When in use, the sewage to be treated is transported into the sewage pool 1 through the sewage inlet pipe 101, and the sewage is blocked by the sewage discharge structure 2 so that the sewage cannot directly enter the impurity removal area in the sewage pool 1. When the sewage needs to be treated, the motor 205 drives the threaded rod 204 to rotate, and the threaded rod 205 drives the sewage discharge gate 202 to rise. The rising sewage discharge gate 202 will allow the sewage to flow into the impurity removal area, and then the floating objects or sediments in the sewage in the impurity removal area are transported to the impurity receiving box 303 through the conveyor belt 302, and then the sewage removed in the impurity removal area is discharged into the dosing chamber in the sewage pool 1 through the outlet pipe 103.

[0037] It should be clear that in the embodiments of the present application, the sewage pool 1 can be a sewage pool 1 capable of treating any sewage, and the sewage inlet pipe 101 can transport any sewage. The sewage pool 1 is not limited to the application scenario of the water plant that requires sewage treatment, but can also be used in other fields that require sewage treatment, such as: chemical industry, textile industry, or biopharmaceutical industry.

[0038] In the embodiments of the present application, there is no limitation on the shape and structure of the sewage pool 1. For example, the sewage pool 1 may be square or circular, or may be Figure 1 and Figure 2 As shown in the rectangular shape, the sewage discharge structure 2 and the impurity removal structure 3 can also be arranged according to the shape and structure of the sewage pool 1.

[0039] It should be clear that in the embodiment of the present application, there is no limit on the number of sewage discharge gates 202. It is easy to understand that the more sewage discharge gates 202 there are, the slower the sewage enters the decontamination area. In actual use, it can be set according to the sewage treatment needs. In one embodiment of the present application, only two sewage discharge gates 202 can be set, for example, Figure 1 and Figure 2 The sewage discharge structure 2 is shown; in the embodiment of the present application, the sewage discharge gate 202 is driven by the motor 205 to rotate the threaded rod 204, and the sewage discharge gate 202 is raised so that the sewage flows into the sewage removal area. In another embodiment of the present application, as long as the sewage discharge gate 202 can be raised, for example, a slide rail and a slider, a chain and a sprocket, etc.

[0040] It should be clear that in the embodiment of the present application, there is no limit on the number of the impurity removal structures 3. It is easy to understand that the more the number of conveyor belts 302 is set, the better the floating objects and sediments in the sewage can be cleaned. In actual use, the settings can be made according to the floating objects and sediments in the sewage. In one embodiment of the present application, only one set of impurity removal frames 301 and conveyor belts 302 can be set. For example, Figure 1-Figure 3As shown; in the embodiment of the present application, the conveyor belt 302 is arranged between the inner walls of the impurity removal frame 301, and the conveyor belt 302 is driven to rotate by an external motor, and the impurity removal frame 301 is provided with an impurity discharge port near the bottom side of the top, and the impurity removal port is located just above the impurity receiving box 303, in order to facilitate the conveyance of floating objects or sediments conveyed by the conveyor belt 302 to the impurity receiving box 303. In the embodiment of the present application, it should be clear that in the embodiment of the present application, an inclined plate is installed on the surface of the conveyor belt 302, and the inclined plate is for the convenience of conveying floating objects and sediments in the sewage. It should be clear that in one embodiment of the present application, an outlet pipe 103 is installed on the isolation plate 201, one end of the outlet pipe 103 is located in the decontamination area, and the other end is in the dosing chamber, and the outlet pipes 103 on the decontamination area and the dosing chamber are both installed with electromagnetic valves, which can control the decontamination area to flow into the dosing chamber, and the electromagnetic valve of the outlet pipe 103 in the dosing chamber can prevent the sewage in the decontamination area from being poured into the dosing chamber.

[0041] As can be seen from the foregoing, it should be clear that if the sewage in the decontamination area enters the dosing area through the outlet pipe 103, it is necessary to cooperate with the mobile structure 4 and the dosing structure 5 to put the decontamination agent into the sewage in the dosing chamber to purify the sewage. In the embodiment of the present application, the mobile structure 4 includes a fixed frame 401, and the fixed frame 401 is connected to the outer walls on both sides of the sewage pool 1. A screw rod 404 and a guide rod 411 are respectively arranged between the fixed frames 401, and a slide groove 402 is opened at the bottom end of the fixed frame 401, and a slider 403 is slidably arranged in the slide groove 402. The outer walls of the screw rod 404 and the guide rod 411 are movably arranged with a moving block 405, and the moving block 405 is connected to the slider 403, and a support plate 406 is installed on the top of the moving block 405, and a support plate 406 is installed on the top of the support plate 406. A fixed plate 407, a through hole 410 is provided at the center of the fixed plate 407, a slide rail 408 is symmetrically installed on the top of the fixed plate 407, and a sliding block 409 is slidably arranged between the outer sides of the slide rail 408. In the embodiment of the present application, the movable structure 4 is driven by the motor 205 to rotate the screw rod 404. Because the movable block 405 is threadedly connected to the outer wall of the screw rod 404, the movable block 405 can drive the slider 403 to move in the slide groove 402 while moving. Because a support plate 406 is installed on the top of the movable block 405, and a fixed plate 407 is installed on the top of the support plate 406, a linear reciprocating motion can be formed. In another embodiment of the present application, it can be any linear reciprocating motion structure, such as: an electric slide rail and an electric slider, a linear optical axis, a cylinder and a telescopic rod, etc.

[0042] It should be clear that the dosing structure 5 in the embodiment of the present application can dose the sewage in the dosing chamber. When in use, the required medicine is first put into the feed hopper 503. Two feed hoppers 503 are set on the dosing bucket 501 in the embodiment of the present application. It should be clear that the number of feed hoppers 503 is not specifically displayed, and there can be multiple. In actual use, the number of feed hoppers 503 can be set according to needs. It is easy to understand that if the number of feed hoppers 503 is more, the medicine can be put in according to different needs of sewage treatment. In one embodiment of the present application, only two feed hoppers 503 can be set. For example, Figure 6 The feed hopper 503 shown in the figure can be configured with a plurality of feed hoppers 503 so that chemicals can be fed into the feed hoppers according to the sewage treatment requirements.

[0043] In the embodiment of the present application, the feed hopper 503 is restricted by the baffle plate 507 and the discharge plate 508. The discharge plate 508 is located in the medicine barrel 501. The baffle plate 507 and the discharge plate 508 are rotated by the bidirectional screw 509 to release the medicine into the medicine barrel 501. It should be understood that the baffle plate 507 and the discharge plate 508 rotate in opposite directions. For example, when the baffle plate 507 is open, the discharge plate 508 is in a closed state. Conversely, the discharge plate 508 is open and the baffle plate 507 is closed. In order to better quantitatively release the medicine into the medicine barrel 501, in the embodiment of the present application, the medicine is any medicine that can treat sewage and belongs to the prior art, which will not be described one by one in this application.

[0044] It should be clear that in the embodiment of the present application, when the medicine enters the medicine barrel 501 through the feed hopper 503, a rotating rod 510 is arranged at the center of the inner wall of the top cover 502, and a retaining ring 512 and a fixing ring 511 are fixedly connected to the outer wall of the rotating rod 510, and a thread is arranged on the outer wall of the rotating rod 510, and the thread is located below the retaining ring 512, and the retaining ring 512 is located at the center of the length of the rotating rod 510, and a threaded ring is threadedly connected to the thread of the rotating rod 510, and the threaded ring and the fixing ring 511 are fixedly connected to the outer wall of the rotating rod 510. 11 The outer wall is installed with a hinge seat 513, and a connecting rod is hinged between the inner walls of the hinge seat 513, and a mounting rod is hinged at the other end of the connecting rod. A fixing block 514 is fixedly connected between the mounting rods, and an electric telescopic rod 515 is installed on the outer wall of the fixing block 514, and a cleaning plate 516 is installed at the telescopic end of the electric telescopic rod 515, and the cleaning plate 516 is adapted to the inner wall of the medicine barrel 501. A medicine feeding tube 517 is arranged at the bottom end of the medicine barrel 501, and the medicine feeding tube 517 is located in the through hole 410.

[0045] When using, Figure 6-Figure 8As shown, the motor 205 drives the rotating rod 510 to rotate. Since a thread is provided from the center to the bottom of the rotating rod 510, and a thread ring is threadedly connected to the thread, a hinge seat 513 is installed on the thread ring and the fixed ring 511. By rotating the rotating rod 510, the thread ring can be moved up and down, so that the connecting rod hinged on the hinge seat 513 can be moved up and down, so that the cleaning plate 516 connected by the mounting rod can be folded and opened. In another embodiment of the present application, the hinged state of the hinge seat 513 and the connecting rod is not limited, and the hinge seat 513 and the connecting rod can also be The connection is made through a fixed pin, and it is only necessary to keep the connecting rod able to move up and down on the hinge seat 513 with the rotating rod 510 as the axis. It should also be clear that when the cleaning plate 516 is rotated by the rotating rod 510, the water and the medicine in the medicine barrel 501 can also be fully blended, and then the mixed medicine is discharged into the sewage in the medicine chamber through the medicine tube 517, and other substances in the sewage are cleaned. In the embodiment of the present application, an electromagnetic valve is also installed on the medicine tube 517. In the embodiment of the present application, the electromagnetic valve is a prior art and will not be described one by one in this application.

[0046] It should be clear that in the embodiment of the present application, the motor 205 is connected to the power supply of the peripheral device, and the entire device is connected to the control system of the peripheral device. The control system is a sewage treatment central control system. In the embodiment of the present application, the sewage treatment central control system belongs to the prior art and will not be described one by one in this application.

[0047] 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 limited by the attached embodiments and their equivalents.
