Description

Technical Field

[0001] This utility model relates to the field of wastewater detection technology, and in particular to a device for detecting copper ion content in wastewater. Background Technology

[0002] With the rapid development of industry, the discharge of industrial wastewater has shown a sharp increase. Among the many types of industrial wastewater, copper-containing wastewater has attracted much attention due to its significant harm to the environment and human health. Copper ions have a multifaceted destructive effect on the environmental ecosystem. From the perspective of human health, long-term exposure to environments containing copper ions poses many risks. Therefore, accurately detecting the content of copper ions in wastewater is of vital importance for pollution control and ecological environmental protection.

[0003] When detecting copper ions in wastewater, a reagent that can react with copper ions to produce a colorimetric reaction needs to be added to the wastewater. In the current technology, the reagent is usually added manually by the staff. However, it is not possible to accurately control the amount of reagent during the addition process. When there is too much or too little reagent, it will affect the accuracy of the subsequent copper ion content detection. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: when workers manually add reagents to wastewater, it is impossible to accurately control the amount of reagents during the addition process. When there is too much or too little reagent, it will affect the accuracy of subsequent copper ion content detection. Therefore, this invention proposes a device for detecting copper ion content in wastewater.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for detecting copper ion content in wastewater includes a treatment tank, on which an inlet pipe and an outlet pipe are installed, and inside the treatment tank is a mixing component for mixing and stirring.

[0007] A feed pipe is vertically fixedly installed at the upper end of the processing tank. A valve is installed on the feed pipe. The lower end of the feed pipe extends into the processing tank. A cylindrical tube is fixedly installed at the upper end of the feed pipe. The upper end of the feed pipe is connected to the inside of the cylindrical tube.

[0008] The upper end of the treatment tank has a movable hole, and a movable rod is vertically slidably inserted into the movable hole. The lower end of the movable rod extends into the treatment tank and a float is fixedly installed thereon. An indicator block is fixedly installed at the upper end of the movable rod. An inspection window is provided on the side of the cylindrical tube, and one end of the indicator block points to the inspection window.

[0009] Preferably, a push plate is vertically and slidably installed inside the cylindrical tube, a threaded rod is vertically and rotatably installed on the upper surface of the push plate, a bracket is threaded onto the threaded rod, the bracket is fixedly installed on the upper end of the cylindrical tube, an adjusting block is fixedly installed on the upper end of the threaded rod, a feed hole is opened on the surface of the push plate, and a sealing component for blocking the feed hole is provided on the bracket.

[0010] Preferably, the bracket has an installation hole, and the sealing assembly includes a vertical rod that is slidably inserted into the installation hole, a sealing plug that is fixedly installed at the lower end of the vertical rod, and a pull rod that is fixedly installed at the upper end of the vertical rod. The sealing plug is inserted into the feed hole for sealing.

[0011] Preferably, the mixing assembly includes a rotating shaft vertically rotatably mounted on the processing tank, a drive motor fixedly mounted on the upper end of the processing tank, and a plurality of mixing plates fixedly mounted on the rotating shaft, wherein the plurality of mixing plates are located inside the processing tank.

[0012] Preferably, a helical blade is fixedly mounted on the rotating shaft, and the helical blade is located directly below the plurality of mixing plates.

[0013] Preferably, a sealing ring is fixedly installed on the lower surface of the push plate, and the sealing ring is in sealing sliding contact with the inner wall of the cylindrical tube.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. When wastewater enters the treatment tank, the float, under the action of buoyancy, moves the moving rod and indicator block vertically upward. The operator can add reagent into the cylindrical cylinder according to the position indicated by the indicator block, so that the reagent surface is flush with the lower surface of the indicator block. At this time, the reagent in the cylindrical cylinder reacts with the wastewater in the treatment tank. The position indicated by the indicator block will change according to the amount of wastewater in the treatment tank. Thus, the operator can accurately add the amount of reagent into the cylindrical cylinder according to the position of the indicator block, which can effectively avoid too much or too little reagent and ensure the accuracy of subsequent copper ion content detection.

[0016] 2. The reagent to be added to the wastewater is located between the pusher plate and the cylindrical tube. When adding the reagent, the pusher plate moves vertically downward to push the reagent into the treatment tank, which can prevent the reagent from remaining on the inner wall of the cylindrical tube and affecting the actual amount of reagent added.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5 A device for detecting copper ion content in wastewater includes a treatment tank 1, an inlet pipe and an outlet pipe installed on the treatment tank 1, and a mixing component for mixing and stirring installed inside the treatment tank 1. Wastewater enters the treatment tank 1 through the inlet pipe, reagents are added to the treatment tank 1, the wastewater and reagents are fully reacted by the mixing component, and finally discharged for detection through the outlet pipe.

[0025] A feed pipe 2 is vertically fixedly installed on the upper end of the processing tank 1. A valve is installed on the feed pipe 2. The lower end of the feed pipe 2 extends into the processing tank 1. A cylindrical tube 3 is fixedly installed on the upper end of the feed pipe 2. The upper end of the feed pipe 2 is connected to the inside of the cylindrical tube 3. A movable hole is opened on the upper end of the processing tank 1. A movable rod 4 is vertically slidably inserted into the movable hole. The lower end of the movable rod 4 extends into the processing tank 1 and a float ball 5 is fixedly installed thereon. An indicator block 6 is fixedly installed on the upper end of the movable rod 4. An inspection window 7 is provided on the side of the cylindrical tube 3. One end of the indicator block 6 points to the inspection window 7.

[0026] The ratio between treatment tank 1 and cylindrical cylinder 3 is the same as the reaction ratio between wastewater and reagent. When wastewater is added to treatment tank 1, float 5 floats on the water surface under the action of buoyancy. At this time, moving rod 4 will drive indicator block 6 to move upward. One end of indicator block 6 points to cylindrical cylinder 3. Indicator block 6 moves up and down through float 5. At this time, the staff can add reagent into cylindrical cylinder 3 through inspection window 7 so that the liquid level of reagent is level with the lower surface of indicator block 6. Since float 5 and indicator block 6 rise to the same height, the volume ratio of wastewater in treatment tank 1 to reagent in cylindrical cylinder 3 is the same as the reaction ratio between wastewater and reagent, ensuring that the reagent and wastewater react fully. The staff can accurately add the amount of reagent into cylindrical cylinder 3 according to the position of indicator block 6, which can effectively avoid too much or too little reagent and ensure the accuracy of subsequent copper ion content detection.

[0027] A push plate 8 is vertically and slidably installed inside the cylindrical tube 3. A threaded rod 9 is vertically and rotatably installed on the upper surface of the push plate 8. A bracket 10 is threaded onto the threaded rod 9. The bracket 10 is fixedly installed on the upper end of the cylindrical tube 3. An adjusting block 11 is fixedly installed on the upper end of the threaded rod 9. A feed hole is opened on the surface of the push plate 8. A sealing component for blocking the feed hole is provided on the bracket 10. An installation hole is opened on the bracket 10. The sealing component includes a vertical rod 12 that is vertically slidably inserted into the installation hole, a sealing plug 13 that is fixedly installed on the lower end of the vertical rod 12, and a pull rod 14 that is fixedly installed on the upper end of the vertical rod 12. The sealing plug 13 is sealed and inserted into the feed hole.

[0028] The push plate 8 slides vertically and sealed inside the cylindrical tube 3. By rotating the adjusting block 11, the threaded rod 9 can be rotated. Under the action of the bracket 10, the push plate 8 can be moved up and down inside the cylindrical tube 3. When adding reagent, the push plate 8 is aligned with the indicator block 6. Then, the pull rod 14 is pulled upward, which moves the vertical rod 12 vertically upward, removing the sealing plug 13 from the feed hole. At this time, the reagent is added from the top of the cylindrical tube 3. The reagent will flow into the space between the push plate 8 and the cylindrical tube 3 through the feed hole until the reagent completely fills the space between the push plate 8 and the cylindrical tube 3. Then, the sealing plug 13 is inserted into the feed hole, the valve is opened, and the threaded rod 9 is rotated to move the push plate 8 vertically downward. The push plate 8 can completely push the reagent between the push plate 8 and the cylindrical tube 3 into the treatment tank 1, which can avoid the reagent remaining on the inner wall of the cylindrical tube 3 and affecting the actual amount of reagent added.

[0029] The mixing assembly includes a rotating shaft 15 vertically rotatably mounted on the processing tank 1, a drive motor 16 fixedly mounted on the upper end of the processing tank 1, and multiple mixing plates 17 fixedly mounted on the rotating shaft 15. The multiple mixing plates 17 are all located inside the processing tank 1. A spiral blade 18 is fixedly mounted on the rotating shaft 15, and the spiral blade 18 is located directly below the multiple mixing plates 17.

[0030] The drive motor 16 rotates, causing the rotating shaft 15 to rotate, which in turn drives multiple mixing plates 17 and spiral blades 18 to rotate. The rotation of the multiple mixing plates 17 allows the reagents and wastewater to be fully mixed, while the rotation of the spiral blades 18 can lift the wastewater at the bottom upwards, further improving the mixing efficiency of the reagent-deteriorated wastewater.

[0031] A sealing ring is fixedly installed on the lower surface of the push plate 8. The sealing ring makes a sealing sliding contact with the inner wall of the cylindrical tube 3. The sealing plate ensures the sealing between the push plate 8 and the cylindrical tube 3, preventing the reagent from overflowing from the gap between the push plate 8 and the cylindrical tube 3.

[0032] In this invention, when wastewater is added to the treatment tank 1, the float 5 floats on the water surface under the action of buoyancy. At this time, the moving rod 4 will drive the indicator block 6 to move upward. One end of the indicator block 6 points to the cylindrical cylinder 3. The indicator block 6 moves up and down through the float 5. At this time, the staff can add reagent into the cylindrical cylinder 3 through the inspection window 7 so that the liquid level of the reagent is flush with the lower surface of the indicator block 6. Since the float 5 and the indicator block 6 rise to the same height, the volume ratio of wastewater in the treatment tank 1 to reagent in the cylindrical cylinder 3 is the same as the reaction ratio between wastewater and reagent, ensuring that the reagent and wastewater react fully. The staff can accurately add the amount of reagent into the cylindrical cylinder 3 according to the position of the indicator block 6, which can effectively avoid too much or too little reagent and ensure the accuracy of subsequent copper ion content detection.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
