Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an electrochemical ammonia nitrogen digester. Background Technology

[0002] Electrochemical ammonia nitrogen digestion machines remove ammonia nitrogen using electrochemical methods. During this process, electrode reactions generate substances with strong oxidizing properties, such as hydroxyl radicals. These substances react chemically with ammonia nitrogen, converting it into nitrogen gas or other harmless substances, thus achieving the purpose of ammonia nitrogen digestion.

[0003] Chinese Patent Publication No. CN210012638U discloses an electrochemical ammonia nitrogen digestion device that achieves gradient changes in treatment concentration by varying electrode materials to ensure treatment effectiveness. The device includes a first reaction unit, a second reaction unit, a third reaction unit, a fourth reaction unit, and a fifth reaction unit. The inlet is located at the bottom of the first reaction unit. The first reaction unit is connected to the second reaction unit via an overflow plate. The second reaction unit is connected to the third reaction unit via a bottom opening. The third reaction unit is connected to the fourth reaction unit via an overflow plate. The fourth reaction unit is connected to the fifth reaction unit via a bottom opening. A cathode is located within the first reaction unit, and an anode is located within the second reaction unit. This electrochemical ammonia nitrogen digestion device promotes the decomposition of ammonia nitrogen and total nitrogen in the raw water through the cooperation between inert electrodes and the anode, and by effectively controlling the flow of raw water. The unique structural design of each electrode plate significantly improves the reaction rate and effect with the raw water, while greatly reducing energy consumption.

[0004] However, this device has the following drawbacks in use: Since wastewater typically contains various impurities, organic matter, microorganisms, etc., these substances adhere to the surface of the electrode plates after prolonged contact with the wastewater, forming scale. The accumulation of scale increases the resistance of the electrode plates and reduces their conductivity, thus affecting the efficiency and effectiveness of wastewater treatment. Furthermore, the device requires disassembling the electrode plates one by one, making rapid disassembly and cleaning impossible and impacting efficiency. To address these shortcomings, we propose an electrochemical ammonia nitrogen digester. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Please see Figure 1-4 This utility model provides a technical solution: an electrochemical ammonia nitrogen digester, comprising: a wastewater electrochemical treatment structure, an electrode plate mounting structure, and a fixing structure.

[0029] The wastewater electrochemical treatment structure includes an electrolytic cell 10 and wastewater treatment electrode plates 11 disposed on the inner wall of the electrolytic cell 10. The wastewater treatment electrode plates 11 are composed of an anode plate and a cathode plate. After the wastewater treatment electrode plates 11 are energized, an oxidation reaction occurs at the electrolyte interface. Anode: 2Cl - →Cl2↑+2e - Cathode: 2H₂O + 2e⁻ - →H₂↑+2OH - The generated Cl2 and OH - The formation of strong oxidizing hypochlorous acid (HClO) decomposes ammonia nitrogen (NH3-N) into N2, thereby enabling wastewater treatment.

[0030] The electrode mounting structure includes a telescopic support frame and a clamping assembly disposed on the upper surface of the telescopic support frame. The telescopic support frame includes electric telescopic rods 20 disposed on both sides of the electrolytic cell 10 and mounting plates 21 fixedly installed on the telescopic ends of the two electric telescopic rods 20. A base 22 is fixedly installed on the lower surface of the electric telescopic rods 20, and the base 22 is designed to enhance the support stability.

[0031] The clamping assembly includes a mounting bracket 30 fixedly mounted on the upper surface of the mounting plate 21, a threaded post 31 rotatably connected to the inner wall of the mounting bracket 30, multiple movable clamping plates 32 with equidistant helical drive on the surface of the threaded post 31, multiple fixed clamping plates 33 equidistantly fixedly mounted on the lower surface of the mounting plate 21, and multiple track grooves 34 equidistantly opened on the surface of the mounting plate 21 for the movable clamping plates 32 to pass through. A pin 40 is fixedly mounted on the side of the movable clamping plate 32 near the fixed clamping plate 33. The surfaces of the fixed clamping plate 33 and the wastewater treatment electrode plate 11 are provided with insertion holes 41 for the pin 40 to be inserted. The right end of the threaded post 31 extends to the outside of the mounting bracket 30 and is provided with a handle 50. Rotating the handle 50 can drive the threaded post 31 to rotate. By using the helical drive between the threaded post 31 and the movable clamping plate 32, the movable clamping plate 32 can be driven to slide left and right along the inner wall of the track groove 34.

[0032] The movable clamping plate 32, the fixed clamping plate 33, and the pin 40 are all made of polytetrafluoroethylene or ceramic insulating material. The use of insulating material can avoid the risk of short circuit caused by the clamping components clamping the wastewater treatment electrode plate 11, thereby improving the safety level of the equipment.

[0033] After placing the wastewater treatment electrode 11 between the movable clamp 32 and the fixed clamp 33, turning the handle 50 clockwise will drive the movable clamp 32 closer to the fixed clamp 33, thereby driving the pin 40 to be inserted into the insertion hole 41 on the wastewater treatment electrode 11 and the fixed clamp 33, thus clamping and fixing the wastewater treatment electrode 11. Conversely, turning the handle 50 in the opposite direction will drive the movable clamp 32 to disengage from the fixed clamp 33.

[0034] By using the threaded column 31 to drive the moving clamp 32 to approach or move away from the fixed clamp 33, multiple wastewater treatment electrode plates 11 can be clamped and released at one time, realizing batch assembly and disassembly of the wastewater treatment electrode plates 11. At the same time, with the rise of the telescopic support frame, the wastewater treatment electrode plates 11 can be quickly removed from the electrolytic cell 10. After moving the telescopic support frame to move the wastewater treatment electrode plates 11 out of the electrolytic cell 10, the wastewater treatment electrode plates 11 can be disassembled and cleaned, greatly shortening the maintenance time.

[0035] The fixing structure is set on both sides of the electrolytic cell 10 to fix the electric telescopic rod 20. The fixing structure includes a first semi-circular ring 60 fixedly installed on both sides of the electrolytic cell 10, and a second semi-circular ring 61 tightly fixed on the surface of the first semi-circular ring 60 by bolts. The inner diameter of the first semi-circular ring 60 and the second semi-circular ring 61 are perfectly matched with the outer diameter of the electric telescopic rod 20. The first semi-circular ring 60 and the second semi-circular ring 61 are detachable. When the electric telescopic rod 20 moves to both sides of the electrolytic cell 10, the first semi-circular ring 60 and the second semi-circular ring 61, together with the bolts, can clamp and fix the electric telescopic rod 20 to both sides of the electrolytic cell 10, thereby improving the stability of the electrode plate installation structure.

[0036] Specifically, the working principle and operation method of this utility model are as follows:

[0037] Install wastewater treatment electrode 11: Rotate handle 50 to drive threaded column 31 to rotate, so that multiple movable clamping plates 32 driven by screw drive move synchronously along track groove 34, forming opposing clamping force with fixed clamping plate 33, thereby clamping multiple wastewater treatment electrode 11.

[0038] Move the two electric telescopic rods 20 to both sides of the electrolytic cell 10 respectively. At this time, the wastewater treatment electrode plate 11 is directly above the electrolytic cell 10. Then, the electric telescopic rods 20 and the electrolytic cell 10 can be fixed together using the fixing structure.

[0039] The drive electric telescopic rod 20 drives the mounting plate 21 to descend vertically, immersing the wastewater treatment electrode 11 into the electrolytic cell 10. Then, the wastewater treatment electrode 11 is energized to treat the wastewater.

[0040] Cleaning the wastewater treatment electrode plate 11: Loosen the bolts to separate the second semi-circular ring 61 from the first semi-circular ring 60. Then, start the electric telescopic rod 20 to raise the mounting plate 21 to the highest position. At this time, the wastewater treatment electrode plate 11 is removed from the electrolytic cell 10. Then, move the telescopic support frame to move the wastewater treatment electrode plate 11 out of the electrolytic cell 10. Drive the electric telescopic rod 20 to drive the mounting plate 21 to descend vertically and lower the wastewater treatment electrode plate 11. Then, rotate the handle 50 to move the moving clamp 32 away from the fixed clamp 33. At this time, the pin 40 is removed from the wastewater treatment electrode plate 11, so that the entire set of wastewater treatment electrode plates 11 can be taken out for cleaning and maintenance.

[0041] 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 based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
