Description

Technical Field

[0001] This utility model relates to the field of cyanobacteria treatment technology, specifically to a cyanobacteria treatment device. Background Technology

[0002] Numerous studies have shown that the key to solving eutrophication lies in effectively controlling the concentration of phosphorus nutrients in water bodies. With increasingly stringent standards for phosphorus-containing wastewater discharge in my country, governments and businesses are forced to prioritize its treatment.

[0003] Existing methods for treating cyanobacteria mainly involve adding polyaluminum chloride (PAC) to the water as a water purification agent. During the hydrolysis process, physical and chemical processes such as coagulation, adsorption, and precipitation occur. For some industrial wastewater that is difficult to treat, PAC is used as the base and other agents are added to formulate composite PAC.

[0004] However, this treatment method produces 80% unidentified byproducts that pollute water bodies. Furthermore, the cost of using polyaluminum chloride (PAC) as a water purification agent is high, and long-term use will also incur significant labor costs. Utility Model Content

[0005] The purpose of this invention is to provide a blue-green algae treatment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a blue-green algae treatment device, comprising a support frame and a treatment box installed on the top left side of the support frame, wherein a water inlet pipe is fixedly installed on the top right side of the treatment box, and a treatment device is provided inside the support frame, the treatment device comprising an electrolysis mechanism and a compaction mechanism.

[0007] The electrolysis mechanism includes a motor, a rotating shaft, a periodically programmable inverter, a DC power supply box, conductive connecting posts, a mounting frame, and aluminum electrode plates. The motor is fixedly mounted on the top right side of the support frame. The rotating shaft is connected to the output shaft of the motor.

[0009] Preferably, the periodically programmed inverter reverses the polarity of each aluminum electrode plate at regular intervals, and the aluminum electrode plates are symmetrically distributed at equal intervals on the outer surface of the DC power supply box.

[0010] Preferably, the bearing housing is fixedly installed on the top left and right sides of the load-bearing frame, and a ball bearing is installed inside the bearing housing. The rotating shaft passes through the inner ring of the ball bearing and is rotatably connected to it. The ball bearings at both ends make the rotating shaft rotate more smoothly.

[0011] Preferably, a compaction box is fixedly installed at the bottom of the load-bearing frame. The compaction mechanism includes a hydraulic cylinder, a pressure rod, a pressure plate, a collection box, a telescopic spring, and a push plate. The hydraulic cylinder is fixedly installed at the bottom right side of the load-bearing frame. The pressure rod is fixedly connected to the output end of the hydraulic cylinder.

[0013] Preferably, the telescopic spring is a lightweight spring, and the outer surface of the push plate is slidably connected to the inner wall of the compaction box. When the telescopic spring is compressed to its maximum compression, it will rebound under the action of its own restoring force.

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

[0015] 1. This cyanobacteria treatment device utilizes aluminum oxide and other active substances generated during the electrolysis process of aluminum electrode plates to destroy the cell structure of cyanobacteria, thereby achieving the effect of removing cyanobacteria. During the electrolysis process, the aluminum anode is oxidized, releasing aluminum ions. These aluminum ions react with hydroxide ions in the water to form aluminum hydroxide precipitate, which adsorbs and removes cyanobacteria from the water. Compared with the traditional use of PAC to treat cyanobacteria, this device uses electrochemistry for cyanobacteria treatment, reducing treatment costs and avoiding the generation of unknown byproducts, thus preventing water pollution.

[0016] 2. In this cyanobacteria treatment device, after the cyanobacteria on the aluminum electrode plate are washed off by a water gun, the cyanobacteria fall into the compaction box. By activating the hydraulic cylinder, the output end of the hydraulic cylinder pushes the pressure rod, which pushes the pressure rod to slide on the inner wall of the compaction box, thereby pushing the cyanobacteria that have fallen into the compaction box into the collection box for compaction, thus completing the collection of cyanobacteria.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 This utility model provides a technical solution:

[0026] A blue-green algae treatment device includes a support frame 1 and a treatment box 3 installed on the top left side of the support frame 1. A water inlet pipe 4 is fixedly installed on the top right side of the treatment box 3. The device is characterized in that the support frame 1 is equipped with a treatment device, which includes an electrolysis mechanism and a compaction mechanism.

[0027] The electrolysis mechanism includes a motor 5, a rotating shaft 501, a periodically programmable inverter 503, a DC power supply box 504, a conductive connecting post 505, a mounting frame 506, and an aluminum electrode plate 507. The motor 5 is fixedly installed on the top right side of the support frame 1. The rotating shaft 501 is connected to the output shaft of the motor 5. The periodically programmable inverter 503 is fixedly installed on the right side of the outer surface of the rotating shaft 501. The DC power supply box 504 is fixedly installed in the middle of the outer surface of the rotating shaft 501. The mounting frame 506 is fixedly connected to the outer surface of the DC power supply box 504. The conductive connecting post 505 is fixedly installed on the outer surface of the DC power supply box 504. The aluminum electrode plate 507 is installed inside the mounting frame 506.

[0028] Two conductive connecting posts 505 are provided, which are respectively used as positive and negative terminals and electrically connected to the aluminum electrode plate 507. The conductive connecting posts 505 are also electrically connected to the DC power supply box 504, and the periodic programmable inverter 503 is electrically connected to the DC power supply box 504.

[0029] The periodically programmed inverter 503 reverses the polarity of each aluminum electrode plate 507 at regular intervals. That is, the aluminum electrode plate 507 that was originally used as the anode is used as the cathode, and vice versa. The periodically programmed inverter 3 is set to anode-cathode reversal period of 100s, 500s, 800s, or 1000s. The current density of the DC power supply box 504 is 5.00~15.00A / m. 2 The effect of treating algae concentration can be adjusted by adjusting the current density. Aluminum electrode plates 507 are symmetrically distributed at equal intervals on the outer surface of DC power supply box 504.

[0030] The aluminum electrode plate 507 utilizes aluminum oxide and other active substances generated during electrolysis to destroy the cell structure of cyanobacteria, thereby achieving the effect of removing cyanobacteria. During the electrolysis process, the aluminum anode of the aluminum electrode plate 507 is oxidized, releasing aluminum ions. These aluminum ions react with hydroxide ions in the water to form aluminum hydroxide precipitate, thereby adsorbing and removing cyanobacteria from the water. The strong oxidants such as active oxygen and hydroxyl radicals generated during the electrolysis process can also effectively kill cyanobacteria cells.

[0031] The bearing housing 502 is fixedly installed on the top left and right sides of the load-bearing frame 1. The bearing housing 502 is equipped with ball bearings. The rotating shaft 501 passes through the inner ring of the ball bearing and is rotatably connected to it. The ball bearings at both ends make the rotating shaft 501 rotate more smoothly.

[0032] A compaction box 6 is fixedly installed at the bottom of the load-bearing frame 1. The compaction mechanism includes a hydraulic cylinder 601, a pressure rod 602, a pressure plate 603, a collection box 604, a telescopic spring 605, and a push plate 606. The hydraulic cylinder 601 is fixedly installed at the bottom right side of the load-bearing frame 1. The pressure rod 602 is fixedly connected to the output end of the hydraulic cylinder 601. The pressure plate 603 is fixedly connected to the end of the pressure rod 602 away from the hydraulic cylinder 601. The collection box 604 is fixedly installed on the left side of the compaction box 6. The telescopic spring 605 is fixedly connected to the inside right side of the collection box 604. The push plate 606 is fixedly connected to the end of the telescopic spring 605 away from the collection box 604.

[0033] The compaction box 6 is trapezoidal, wider at the top and narrower at the bottom. The outer surface of the pressure plate 603 is slidably connected to the inner wall of the compaction box 6. The top of the pressure plate 603 is located 20cm below the lowest point of the aluminum electrode plate 507. The telescopic spring 605 is a lightweight spring. The outer surface of the push plate 606 is slidably connected to the inner wall of the compaction box 6. After the cyanobacteria are pushed into the collection box 604 and compacted, the cyanobacteria will come into contact with the push plate 606, causing the push plate 606 to be squeezed and further compress the telescopic spring 605. When the telescopic spring 605 is compressed to its maximum compression, it will rebound under its own restoring force, thereby preventing the push plate 606 from being over-compressed and facilitating the removal of the compacted cyanobacteria.

[0034] After the cyanobacteria are electrolyzed, a water gun is used to wash the cyanobacteria off the aluminum electrode plate 507. The cyanobacteria fall into the compaction box 6. By activating the hydraulic cylinder 601, the output end of the hydraulic cylinder 601 pushes the pressure rod 602. The pressure rod 602 pushes the pressure rod 603 to slide on the inner wall of the compaction box 6, thereby pushing the cyanobacteria that fell into the compaction box 604 into the collection box 604 for compaction, thus completing the collection of cyanobacteria.

[0035] Working principle: When treating sewage, sewage is first introduced into treatment tank 3 through inlet pipe 4. Then, motor 5 is started. The output shaft of motor 5 drives rotating shaft 501 to rotate. Rotating shaft 501 drives DC power supply box 504, mounting frame 506 and aluminum electrode plate 507 to rotate. After the DC power supply box 504 powers the conductive connecting post 505, it acts as the cathode and anode respectively and is connected to aluminum electrode plate 507. The aluminum oxide and other active substances produced by aluminum electrode plate 507 during electrolysis destroy the cell structure of cyanobacteria, thereby achieving the effect of removing cyanobacteria. With the periodic rotation of the six aluminum electrode plates 507, the treatment effect on cyanobacteria is further improved.
