Description

Technical Field

[0001] This utility model relates to the field of electrolysis devices, and in particular to an electrolysis device for high-salt and high-organic wastewater. Background Technology

[0002] High-salt and high-organic wastewater refers to industrial wastewater that contains both high concentrations of salt and large amounts of organic pollutants. High-salt and high-organic wastewater electrolysis devices are equipment that use the principle of electrolysis to treat wastewater containing both high concentrations of salt and large amounts of organic matter. Their main function is to use the principle of electrolysis to decompose harmful organic matter in wastewater into harmless substances under the condition of electricity, while also removing salt.

[0003] However, the existing electrolysis devices for high-salt and high-organic wastewater on the market have relatively fixed structures and mostly use welded connections. This makes it inconvenient for operators to install and disassemble the stirring rods when they need to be cleaned and replaced, thus reducing work efficiency. In addition, the electrolysis tank itself continuously generates heat during the electrolysis process. Most of them use built-in cooling plates. Suspended solids, precipitates or reaction products in high-salt and high-organic wastewater can easily adhere to the surface of the coils, forming a layer of dirt, which greatly reduces heat transfer efficiency and blocks the pipes, thereby reducing the working efficiency of the electrolysis device.

[0004] Therefore, those skilled in the art have provided an electrolysis device for high-salt, high-organic wastewater to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an electrolysis device for high-salt and high-organic wastewater. By cooperating with a water tank, water pump, heat conduction pipe and water inlet pipe, the wastewater is heated by the heat generated by the electrolysis tank, thereby reducing the operating cost of the electrolysis tank. Furthermore, the use of the slot, the locking block and the rotating handle in the second groove, the second threaded rod, the rotating block, the limiting block and the fixing block facilitates the cleaning of the stirring rod by the operator.

[0006] To achieve the above objectives, this utility model provides an electrolysis device for high-salt and high-organic wastewater, comprising a base plate, a circulation component, an electrolysis tank, and a stirring component. The circulation component is located at the rear end of the upper surface of the base plate, the electrolysis tank is located at the front end of the upper surface of the base plate, and the stirring component is located in the middle of the upper surface of the base plate. The circulation component includes a water tank, and a water pump is fixedly connected to one side of the outer wall of the water tank. The lower surface of the circulation component is fixedly connected to the base plate, and a control panel is fixedly connected to the front end of one side of the outer wall of the base plate. An electrolysis cover is located at the top of the electrolysis tank, and threaded holes are provided at each of the four corners of the upper surface of the electrolysis tank. Fastening bolts are provided at each of the four corners of the upper surface of the electrolysis cover. A one-way pipe is continuously connected to the middle of the upper surface of the electrolysis cover, and a flange is fixedly connected to the upper end of the outer wall of the one-way pipe. A water pump is fixedly connected to the upper end of the other side of the outer wall of the water tank, and a heat-conducting pipe is continuously connected to the drain outlet of the water pump.

[0007] The stirring assembly includes a stirring rod. A first groove is formed at the front end of the upper surface of the base plate. A servo motor is fixedly connected to the middle of the bottom surface of the first groove. A connecting rod is fixedly connected to the output shaft of the servo motor. The upper end of the connecting rod passes through the electrolysis tank and extends into the interior of the electrolysis tank. A locking block is fixedly connected to both sides of the upper surface of the connecting rod. A slot is formed in the middle of the adjacent side of the locking block. A locking groove is formed on both sides of the lower surface of the stirring rod. The locking block is engaged with the locking groove. A second groove is formed in the middle of the stirring rod. A second threaded rod is rotatably connected to the middle of the inner wall of one side and the inner wall of the other side of the second groove. A rotating handle is fixedly connected to one side of the outer wall of the second threaded rod. A rotating block is threadedly connected to the middle of the outer wall of the second threaded rod. Limit blocks are fixedly connected to both sides of the outer wall of the other side of the rotating block.

[0008] The above technical solution establishes a preliminary connection through the snap-fit ​​connection between the card block and the card slot, ensuring that the stirring rod will not fall off during rotation.

[0009] Furthermore, the lower ends of the fastening bolts all penetrate the electrolytic cap and are threadedly connected to the threaded holes;

[0010] The above technical solution uses bolts to fix the electrolysis cover to the electrolysis box instead of welding, making it easier to clean, inspect or replace the inside of the electrolysis box.

[0011] Furthermore, two electrode plates are connected through the two sides of the upper surface of the electrolysis cover, and wires are fixedly connected to the middle of the upper surface of the two electrode plates. Diaphragms are fixedly connected to both sides of the inner wall of the electrolysis tank.

[0012] The above technical solution, through the combined use of wires, two electrode plates and a diaphragm, with the two electrode plates serving as the anode and cathode respectively, forms a complete electrolysis circuit. This circuit can efficiently decompose organic matter and inorganic salts in wastewater and prevent organic matter from entering the cathode area through the diaphragm, thereby preventing cross-contamination of reaction products.

[0013] Furthermore, a No. 2 water outlet valve is connected through the middle of the lower end of the outer wall on one side of the electrolysis tank, and a No. 4 flange is fixedly connected to one side of the outer wall of the No. 2 water outlet valve. A No. 2 water inlet valve is connected through the middle of the lower end of the outer wall on the other side of the electrolysis tank, and a No. 5 flange is fixedly connected to the other side of the outer wall of the No. 2 water inlet valve.

[0014] Through the above technical solution, the coordinated use of No. 2 outlet valve, No. 4 flange, No. 2 inlet valve and No. 5 flange enables the directional inflow of wastewater and the outflow of treated wastewater, while the flanges ensure the sealing, stability and maintainability of the connection.

[0015] Furthermore, a No. 1 outlet valve is connected through the middle of the outer wall of the rear end of the water tank, and a No. 2 flange is fixedly connected to the rear end of the outer wall of the No. 1 outlet valve. A No. 1 inlet valve is connected through the middle of the upper surface of the water tank, and a No. 3 flange is fixedly connected to the upper end of the outer wall of the No. 1 inlet valve.

[0016] Through the above technical solution, the coordinated use of No. 1 outlet valve, No. 2 flange, No. 1 inlet valve and No. 3 flange enables the directional inflow of water into the water tank and the outflow of treated water, while the flanges ensure the sealing, stability and maintainability of the connection.

[0017] Furthermore, the water pump has an inlet pipe that is connected to the water tank.

[0018] By using the above technical solution, the water inlet pipe is connected to the water tank, ensuring that the water pump always has enough water to pump, thus preventing the water pump from running dry or being damaged due to lack of water.

[0019] Furthermore, the heat-conducting pipe is wound around the outside of the electrolysis tank, and the rear end of the heat-conducting pipe is connected through the water tank.

[0020] With the above technical solution, the heat pipe is wound around the outside of the electrolysis tank and the rear end of the heat pipe is connected to the water tank. This allows the heat pipe to directly absorb the heat emitted from the outer wall of the electrolysis tank. At the same time, when the high-temperature fluid flows back to the water tank, the water tank plays a heat storage role, thereby improving the efficiency of the electrolysis device.

[0021] Furthermore, on the other side of each limiting block, a fixing block is fixedly connected through the second groove and the stirring rod to the outside of the stirring rod, and the fixing block is snapped into the groove hole.

[0022] The above technical solution, by connecting the fixing block and the slot, forms a stable connection structure, while also facilitating the installation and disassembly of the stirring rod by the operator.

[0023] This utility model has the following beneficial effects:

[0024] 1. The present invention proposes an electrolysis device for high-salt and high-organic wastewater. By using a water tank, a water pump, a heat pipe, and an inlet pipe in combination, a closed-loop heat dissipation circulation water circuit is formed. The heat pipe is used to quickly conduct and absorb the heat generated inside the electrolysis device, forming a continuous and effective heat removal process. This allows the electrolysis device to operate stably within a suitable temperature range, avoiding the reduction in heat transfer efficiency caused by the build-up cooling plate adsorbing precipitates in the wastewater. This improves the working efficiency of the electrolysis device.
