Positive and negative electrode rods are fixed to the anode and cathode plates, respectively. A diaphragm filter screen separates the anode and cathode plates into interconnected anode and cathode regions. An air inlet and a liquid inlet are located at the bottom of the mesh box wall corresponding to the cathode region. This invention offers advantages such as simple structure, low cost, and ease of use. It can simultaneously generate sodium hypochlorite and hydrogen peroxide in a pulp bleaching tank containing sodium chloride solution for bleaching pulp. Furthermore, the residual bleaching liquid does not need to be discharged and can be reused, reducing environmental pollution.

[0004] However, the device lacks effective anode cleaning equipment, and the gas produced by the reaction is prone to stagnation, which may pose a safety hazard. Summary of the Invention

[0022] 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.

[0023] Example 1

[0024] Please see Figure 1-4 This utility model provides a sodium hypochlorite and hydrogen peroxide combined generator, including a housing 2, a mounting frame 1, and a scraper 7. The mounting frame 1 is fixedly connected to one outer wall of the housing 2. A rotating motor 12 is fixedly connected to the upper outer wall of the mounting frame 1. The output shaft of the rotating motor 12 is fixedly connected to the rotation center of the lead screw 13. A limit ring 8 is fixedly connected to the lower end of the lead screw 13. A second through hole is provided at the upper end of the mounting frame 1, and a second limit rod 15 is provided in the second through hole. The lower end of the second limit rod 15 is fixedly connected to a moving block 6. In use, one end of the second limit rod 15 is fixedly connected to the moving block 6, and the other end passes through the second through hole at the upper end of the mounting frame 1, which can guide the moving block 6 and ensure the stability of the moving block 6 moving along the axial direction of the lead screw 13 when the lead screw 13 rotates, avoiding the rotational deviation of the moving block 6, thereby ensuring the effective scraping of impurities on the surface of the anode plate 5.

[0025] Example 2

[0026] Please see Figure 1-4In this embodiment, the lead screw 13 is provided with a movable block 6, and the movable block 6 is provided with a first threaded hole. The lead screw 13 is connected to the movable block 6 through the first threaded hole. The movable block 6 is provided with a first through hole, and a first limiting rod 14 is provided in the first through hole. One end of the first limiting rod 14 is fixedly connected to the outer wall of one side of the scraper 7. In use, the movable block 6 forms a threaded transmission pair with the lead screw 13 through the first threaded hole. When the lead screw 13 rotates, the movable block 6 moves up and down along the axial direction of the lead screw 13 under the action of the thread. One end of the first limiting rod 14 is fixedly connected to the scraper 7, and the other end passes through the first through hole in the movable block 6, which can limit the scraper 7 and ensure that the scraper 7 can move stably when adjusting the lateral position, and avoid the scraper 7 from rotating and deviating.

[0027] A scraper 7 is provided on one side of the movable block 6. The scraper 7 has a bearing inside and is connected to one end of the threaded rod 9 through the bearing. The other end of the threaded rod 9 is fixedly connected to the handle 10. The movable block 6 has a second threaded hole. The scraper 7 is connected to the movable block 6 by inserting the threaded rod 9 into the second threaded hole. In use, the scraper 7 is connected to the threaded rod 9 through the bearing, so that when the handle 10 is turned to drive the threaded rod 9 to rotate, the scraper 7 will not rotate with the threaded rod 9, but will only move in the axial direction of the threaded rod 9. The operator can adjust the distance and contact pressure between the scraper 7 and the anode plate 5 by turning the handle 10 according to the adhesion of impurities on the surface of the anode plate 5, the shape of the anode plate 5 and the surface condition.

[0028] The chamber 2 is equipped with a diaphragm 20, which divides the chamber 2 into an anode pool 16 and a cathode pool 17. An anode plate 5 is provided on one inner wall of the anode pool 16, and a cathode plate 11 is provided on one inner wall of the cathode pool 17. The diaphragm 20 is made of a material with selective permeability, which allows specific ions to pass through, maintains the electroneutrality of the electrolyte solution, ensures the smooth progress of the electrolysis reaction, and improves the generation efficiency and purity of sodium hypochlorite and hydrogen peroxide.

[0029] Both the scraper 7 and the moving block 6 are located inside the anode pool 16 and close to the anode plate 5.

[0030] A bracket 18 is fixedly connected to one side of the upper end of the housing 2. An air pump 4 is fixedly connected to the outer wall of the upper end of the bracket 18. The air pump 4 is equipped with an air pipe 3. When in use, the air pump 4 delivers gas into the cathode cell 17 through the air pipe 3, which can stir the electrolyte, promote the exchange of reaction ions and the transfer of matter, and make the electrolysis reaction more uniform and efficient. At the same time, the airflow can accelerate the air flow speed in the cathode cell 17, and discharge the gas generated by the reaction in time, reducing the concentration of reaction gas accumulation in the cathode cell 17.

[0031] The outer wall of the air pipe 3 is provided with a pipe clamp 19, which is fixedly connected to the inner wall of the box 2. The air pipe 3 is located in the cathode pool 17. During use, the pipe clamp 19 is fixedly connected to the inner wall of the box 2 to fix the air pipe 3, ensuring that the position of the air pipe 3 in the cathode pool 17 is stable. This prevents the air pipe 3 from shifting, shaking, or even falling off due to airflow impact, vibration, etc. during the gas delivery process by the air pump 4, and ensures that the gas can be stably and accurately delivered to the cathode pool 17.

[0032] Instructions for use: During use, impurities in the electrolyte may undergo oxidation to form insoluble compounds that adhere to the surface of the anode plate 5. Operators use wrenches or other tools to rotate the handle 10, causing the threaded rod 9 to rotate, thereby adjusting the position of the scraper 7. This ensures the scraper 7 makes full contact with the impurities adhering to the surface of the anode plate 5. The rotating motor 12 drives the lead screw 13 to rotate, causing the moving block 6 to rise and fall together with the scraper 7. When it reaches the height range of the anode plate 5, it contacts the surface of the anode plate 5, generating friction to scrape away the impurities. This keeps the surface of the anode plate 5 clean, allowing the electrode reaction to proceed more fully and efficiently, thus improving the generation efficiency and yield of sodium hypochlorite and hydrogen peroxide. In the cathode cell 17, the electrolytic reaction at the cathode plate 11 requires oxygen and produces hydrogen gas after the reaction. Therefore, a gas pipe 3 is connected to the anode cell 16 to stir the electrolyte, promoting ion exchange and mass transfer, while simultaneously accelerating the airflow within the cathode cell 17 to prevent the accumulation of reaction-generated gas and potential safety risks.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
