Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to an electrolytic cell with a liquid level display for treating landfill leachate wastewater. Background Technology

[0002] Landfill leachate is a high-concentration organic wastewater produced during the dumping and landfilling of waste due to biochemical degradation and the infiltration of rainwater and groundwater. Its effluent still contains recalcitrant organic matter, ammonia nitrogen, and other pollutants. If discharged directly without effective treatment, it will cause serious pollution to soil, water bodies, and the ecological environment.

[0003] In landfill leachate effluent treatment, electrolysis is commonly used. This involves pumping the effluent into an electrolytic cell for electrolysis, followed by the discharge of the electrolyzed water. Existing electrolytic cells typically include a level gauge to monitor the level of the effluent. However, since these level gauges are often electronically controlled, they may fail to display the effluent level in case of malfunction, leading to excessive effluent extraction, reduced electrolysis efficiency, and potential safety hazards. Therefore, we propose an electrolytic cell with a level display for landfill leachate effluent treatment. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an electrolytic cell with a liquid level display for the treatment of landfill leachate tailwater, so as to solve the technical problem that the liquid level gauge used in the current electrolytic cell cannot be timely in knowing the tailwater liquid level height when it malfunctions, which poses a safety hazard during the electrolysis process.

[0005] To solve the above technical problems, the present invention provides the following technical solution: an electrolytic cell with liquid level display for treating landfill leachate tailwater, comprising a treatment tank with a cover plate, wherein a buoy assembly is movably installed on the wall of the cover plate of the treatment tank, and the lower end of the buoy assembly is located inside the treatment tank, and a liquid level display plate movably connected to the buoy assembly is installed on the top of the cover plate of the treatment tank.

[0006] The buoy assembly includes a hollow floating disc, and an indicator tube is fixedly provided on the top of the floating disc, passing through the wall of the treatment tank cover plate, and an indicator element is fixedly provided at the upper end of the indicator tube;

[0007] The liquid level display panel includes a vertical plate fixed to the top of the treatment tank cover. A mounting groove is provided on the side of the vertical plate away from the indicator. A scale that cooperates with the indicator is fixedly installed inside the mounting groove. A movable groove that is movably connected to the indicator is provided on the wall of the vertical plate.

[0008] This invention places the bottom of the buoy assembly inside the treatment tank. When tailwater is added to the treatment tank, the rise in water level lifts the bottom of the buoy assembly, causing the indicator on top of the buoy assembly to move upward. In this way, the indicator and the liquid level display panel can intuitively show the height of the tailwater level. This structure can also help to understand the tailwater level when the electronic level gauge malfunctions, reducing the problem of excessive tailwater addition affecting the electrolysis effect and improving the safety of the electrolysis operation.

[0009] Preferably, a support ring is fixedly installed on the top of the treatment pool outside the buoy assembly, and a number of rotatable balls are arranged in a ring on the inner wall of the support ring. A number of limiting grooves that engage with the balls are provided on the outer wall of the buoy assembly.

[0010] Preferably, the indicator includes a cap threaded to the top of the indicator tube, the top of the cap is fixedly provided with a cap, the side of the fixing block is integrally constructed with an extension plate passing through the movable groove, and the side end of the extension plate is fixedly installed with an indicator strip near the scale.

[0011] Preferably, an indicator piece is integrally formed on the side of the indicator strip near the scale, and the side end of the indicator piece is attached to the scale strip on the surface of the scale.

[0012] Preferably, the outer edge of the support ring is fixed with a connecting plate that fits against the top of the treatment tank cover, and the connecting plate and the cover are threadedly connected by screws.

[0013] Preferably, the outer wall of the top of the indicator tube has a plurality of limiting blocks arranged in a ring, and the bottom of the plurality of limiting blocks is attached to the top of the support ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model places the bottom of the buoy assembly inside the treatment tank. When adding tailwater to the treatment tank, the rise in water level will lift the bottom of the buoy assembly, causing the indicator on the top of the buoy assembly to move upward. In this way, with the cooperation of the indicator and the liquid level display panel, the height of the tailwater liquid level can be intuitively understood. This structure can also help to understand the tailwater liquid level when the electronic liquid level sensor malfunctions, reduce the problem of excessive tailwater addition affecting the electrolysis effect, and improve the safety of electrolysis operation.

[0016] 2. This utility model also features a ball bearing on the inner wall of the support ring that can cooperate with the limiting groove on the outer wall of the float plate. This reduces the contact area of ​​the indicator tube moving up and down, and the rolling ball bearing reduces the resistance of the indicator tube moving up and down, thereby reducing the resistance of the float assembly moving up and down. This reduces the probability that the float assembly will be obstructed when moving the indicator upward, and further improves the accuracy of the indicator indicating the position of the scale on the inner side of the liquid level display plate.

[0023] like Figures 1 to 5 As shown, this utility model relates to an electrolytic cell with a liquid level display for treating landfill leachate tailwater. It includes a treatment tank 1 with a cover plate. A float assembly 2 is movably installed on the wall of the cover plate of the treatment tank 1, with the lower end of the float assembly 2 located inside the treatment tank 1. A liquid level display plate 5, movably connected to the float assembly 2, is installed on the top of the cover plate of the treatment tank 1. The lower end of the float assembly 2, located inside the treatment tank 1, is moved synchronously by the rise of the tailwater, allowing the top end of the float assembly 2 to move to the corresponding height position on the side of the liquid level display plate 5, thus achieving the effect of liquid level display.

[0024] The buoy assembly 2 includes a hollow float 201. An indicator tube 202, passing through the wall of the treatment tank 1 cover, is fixedly installed on the top of the float 201. An indicator element 3 is fixedly installed at the upper end of the indicator tube 202. The liquid level display panel 5 includes a vertical plate 501 fixed to the top of the treatment tank 1 cover. A mounting groove 502 is provided on the side of the vertical plate 501 away from the indicator element 3. A scale 503, which mates with the indicator element 3, is fixedly installed inside the mounting groove 502. A movable groove 504, vertically connected to the indicator element 3, is provided on the wall of the vertical plate 501. The interaction between the indicator element 3 and the liquid level display panel 5 allows for a direct visual understanding of the indicated scale position, improving the convenience of liquid level observation. The movable groove 504 provides space for the indicator element 3 to move up and down.

[0025] In an embodiment of this utility model, a support ring 4 is fixedly installed on the top of the treatment pool 1 outside the buoy assembly 2. Several rotatable balls 401 are arranged in a ring on the inner wall of the support ring 4. Several limiting grooves 203 that engage with the balls 401 are provided on the outer wall of the buoy assembly 2. The engagement of the rotatable balls 401 on the inner side of the support ring 4 with the limiting grooves 203 can reduce frictional resistance when the indicator tube 202 moves up and down, thereby enhancing the smoothness of displacement and reducing the probability that frictional resistance will affect the inaccurate indication position of the side end of the indicator 3.

[0026] In an embodiment of this utility model, the indicator 3 includes a tube cap 301 threadedly connected to the top end of the indicator tube 202. A fixing block 302 is fixedly provided on the top of the tube cap 301. An extension plate 303 passing through the movable groove 504 is integrally constructed on the side of the fixing block 302. An indicator strip 304 close to the scale 503 is fixedly installed on the side end of the extension plate 303. The threaded connection between the tube cap 301 and the indicator tube 202 facilitates the fixed installation position. The extension plate 303 on the side of the fixing block 302 can pass through the movable groove 504 without affecting the up and down movement.

[0027] In an embodiment of this utility model, an indicator piece 305 is integrally formed on the side of the indicator strip 304 near the scale 503, and the side end of the indicator piece 305 is attached to the scale strip on the surface of the scale 503; the indicator piece 305 can more accurately point to the scale strip at the corresponding position, making it easier to observe the tailwater level.

[0028] In an embodiment of this utility model, a connecting plate 402 is fixedly provided on the outer side of the support ring 4 to fit against the top of the cover plate of the treatment tank 1, and a screw 403 is threadedly connected between the connecting plate 402 and the cover plate; the cooperation between the connecting plate 402 and the screw 403 facilitates fixing the installation position of the support ring 4 and makes installation and operation convenient.

[0029] In an embodiment of this utility model, a plurality of limiting blocks 204 are arranged in a ring on the outer wall of the top of the indicator tube 202, and the bottom of the plurality of limiting blocks 204 is attached to the top of the support ring 4; the design of the limiting blocks 204 can limit the installation position of the buoy assembly 2, so that a certain gap is reserved between the bottom of the floating plate 201 and the bottom inner wall of the treatment pool 1.

[0030] Working Principle: This embodiment provides an electrolytic cell with a liquid level display for treating landfill leachate tailwater. In use, by placing the floating plate 201 inside the treatment tank 1, the floating plate 201 floats upwards as tailwater is added to the treatment tank 1, causing the indicator 3 at the top of the indicator tube 202 to move upwards along the side of the liquid level display plate 5. This movement of the indicator 3 indicates different positions on the scale 503, allowing for real-time monitoring of the tailwater level rise. This can replace the liquid level monitoring function when the electronic level gauge malfunctions. The mounting hole 101 on the treatment tank 1 cover has a diameter larger than that of the indicator tube 202. Combined with the ball bearing 401 on the inner wall of the support ring 4 and the limiting groove 203 on the outer wall of the floating plate 201, the floating plate 201 is positioned vertically. This structure reduces the resistance to the vertical movement of the indicator tube 202, improving the smoothness of displacement and further enhancing the accuracy of the liquid level indication.

[0031] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
