Description

Technical Field

[0001] This utility model relates to the field of wool wastewater treatment technology, and in particular to a wool washing wastewater recycling and treatment device. Background Technology

[0002] The wool washing process generates a large amount of wastewater containing pollutants such as suspended solids, grease, and detergents. Direct discharge of this wastewater not only wastes water resources but also causes serious environmental pollution. Therefore, it is crucial to develop efficient wastewater recycling and treatment devices for wool washing. The air flotation machine, as a key device for solid-liquid separation, generates microbubbles by introducing air into the wastewater. This causes suspended solids to adhere to the bubbles and float to the surface, thus achieving separation and purification. It plays an indispensable role in the wool washing wastewater treatment process, and its performance directly affects the effectiveness of wastewater recycling and treatment.

[0003] Currently, common air flotation machines mainly consist of a dissolved air system, a reaction zone, and a separation zone. The dissolved air system dissolves air in water under pressure to form saturated dissolved air water, which generates tiny bubbles when the pressure is reduced. In the reaction zone, wastewater and flocculant are thoroughly mixed, causing suspended particles to form larger flocs. Subsequently, in the separation zone, the flocs, attached to the bubbles, float to the water surface to form scum. The scum is removed by a scum scraper, achieving solid-liquid separation. This traditional air flotation machine, based on the basic principle of air flotation, can perform preliminary treatment of pollutants in wool washing wastewater, meeting the needs of wastewater treatment to a certain extent.

[0004] However, existing air flotation machines suffer from the problem of floating matter easily accumulating and adhering to the inner wall during actual operation. As the air flotation machine continues to operate, a large amount of scum accumulates on the inner wall, which not only easily breeds bacteria and produces odors, but also affects the smoothness of water flow and the uniform distribution of bubbles. Once the water flow is turbulent and the bubble distribution is uneven, the contact and adhesion efficiency between suspended particles and bubbles will decrease, resulting in a poorer air flotation separation effect. This makes it difficult for the water quality of wool washing wastewater to meet the ideal standards, affecting the operating efficiency and treatment effect of the entire wool washing wastewater recycling and treatment device, and increasing the burden and cost of subsequent treatment stages. Therefore, a wool washing wastewater recycling and treatment device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a wool washing wastewater recycling and treatment device, which aims to improve the problems of difficult manual cleaning and affected air flotation effect in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The scraping assembly includes a scraper, the outer wall of which is disposed on the inner wall of the air flotation machine. A motor is fixedly connected to the outer wall of the support, and a transmission belt is fixedly connected to the output end of the motor.

[0015] As a further description of the above technical solution:

[0016] The other end of the sliding column is fixedly connected to a limiting disk, which is disposed inside the fixed housing.

[0017] As a further description of the above technical solution:

[0018] The fixed outer shell has a limiting groove inside, and the outer wall of the limiting disk is slidably connected inside the limiting groove.

[0019] As a further description of the above technical solution:

[0020] A spring is fitted on the outer wall of the sliding column. One end of the spring is fixedly connected to the outer wall of the limiting disc, and the other end of the spring is fixedly connected to the inner wall of the limiting groove.

[0021] This utility model has the following beneficial effects:

[0022] 1.

[0023] 2. In this utility model, when the air flotation machine is operating normally and venting exhaust, the sealing plug moves to compress the spring. When the equipment stops or the internal pressure changes, the spring rebounds and drives the sealing plug to close. This effectively prevents external air from flowing back and avoids impurities and moisture from entering the air flotation machine and interfering with the processing. It solves the problems of unstable internal gas environment and susceptibility of the equipment to external factors, and improves the stability of equipment operation and the reliability of processing effect.

[0031] 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.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a wool washing wastewater recycling and treatment device, including a support 1, which is welded from multiple high-strength Q235B hot-dip galvanized steel pipes. It has good rust prevention and corrosion resistance, and can adapt to the humid and highly corrosive working environment during the wool washing wastewater treatment process. It stably supports the entire device. An air flotation machine 2 is fixedly connected to the top of the support 1. The air flotation machine 2 is the core equipment for wastewater treatment. It is used to separate suspended solids, grease and other pollutants in wool washing wastewater from water through the air flotation principle to achieve preliminary purification and ensure the smooth progress of subsequent treatment processes. The air flotation machine 2 is equipped with a scraping component. A ladder 5 is fixedly connected to the side wall of the support 1. An air pump 8 is fixedly connected to the bottom of the support 1. One end of the air pump 8 is fixedly connected to an air pipe 7. The air pipe 7 is made of pressure-resistant and corrosion-resistant PVC material, which can withstand the high-pressure gas output by the air pump 8 and is not easily corroded by chemicals in the wastewater, ensuring the safety and stability of gas transportation. The other end of the air pipe 7 is located at the bottom of the air flotation machine 2. A limiting component is installed inside the air pipe 7.

[0033] The scraping component includes a scraper 10, which has an arc-shaped structure. Its outer wall is tightly attached to the inner wall of the air flotation machine 2. It is used to scrape off floating objects such as wool fibers and grease clumps that are stuck to the inner wall of the air flotation machine 2. This avoids the water flow state inside the air flotation machine 2 and the reduction of air flotation efficiency due to the long-term adhesion of these floating objects. At the same time, it reduces the corrosion of the inner wall of the equipment and extends the service life of the air flotation machine 2. The scraper 10 is made of polytetrafluoroethylene, which has excellent corrosion resistance and non-stick properties. Even when faced with complex chemicals in wool washing wastewater, it can work stably for a long time and does not easily adhere to impurities. The outer wall of the scraper 10 is set on the inner wall of the air flotation machine 2. The motor 6 is fixedly connected to the outer wall of the bracket 1. The output end of the motor 6 is fixedly connected to the transmission belt 3. The transmission belt 3 is made of high-strength rubber with an embedded Kevlar fiber reinforcement layer, which has good wear resistance and tensile strength and can stably transmit the power of the motor 6. The bracket 1 is fixedly connected to the inside of the fixed column 4. The other side of the transmission belt 3 is rotatably connected to the outer wall of the fixed column 4. The outer wall of the transmission belt 3 is fixedly connected to the connecting ring 9. The bottom of the connecting ring 9 is fixedly connected to the top of the scraper 10.

[0034] Specifically, in the wastewater recycling and treatment process of wool washing, the air flotation machine 2, as a key treatment device, undertakes the important task of separating suspended particles in the wastewater. However, during wastewater treatment, floating particles in the wastewater, such as residual wool fibers and grease deposits, easily adhere to the inner wall of the air flotation machine 2. These attached particles not only affect the normal flow of water inside the air flotation machine 2 and reduce treatment efficiency, but also cause corrosion to the inner wall of the air flotation machine 2 over a long period of time, shortening the service life of the equipment. At this time, the motor 6 installed on the top of the air flotation machine 2 can be started. After the motor 6 is connected to the power supply, it starts to run. With its strong power, it drives the transmission belt 3 to rotate. The transmission belt 3 is tightly connected to the connecting ring 9. As the transmission belt 3 rotates, it drives the connecting ring 9 to move, thereby driving the bottom scraper 10 to slide along the inner wall inside the air flotation machine 2. Wherever the bottom scraper 10 goes, it scrapes off all the particles adhering to the inner wall, removes the hidden danger in time, effectively avoids the inner wall from being corroded by particles, and greatly improves the overall strength and operational stability of the air flotation machine 2.

[0035] Reference Figure 1 , Figure 4 and Figure 5 The limiting components include a sealing plug 12 and an air inlet 11 inside the trachea 7. The air inlet 11 is a circular through-hole structure with its inner wall finely polished to reduce gas flow resistance and ensure air intake efficiency. The outer wall of the sealing plug 12 is slidably connected to the inside of the air inlet 11. A ring array of connecting blocks 14 is fixedly connected inside the trachea 7. The other end of the connecting blocks 14 is fixedly connected to a fixed housing 13. The other end of the sealing plug 12 is fixedly connected to a sliding column 15. The sliding column 15 is a cylindrical structure made of hard aluminum alloy, which is lightweight and high-strength. Its outer wall is smooth and wear-resistant. It is slidably connected inside the fixed housing 13 to transmit the movement of the sealing plug 12 and drive the limiting disc. 17 slides within the fixed housing 13. The outer wall of the sliding column 15 is slidably connected to the inside of the fixed housing 13. The other end of the sliding column 15 is fixedly connected to a limiting disc 17. The limiting disc 17 is a circular plate structure with a diameter slightly smaller than the inner diameter of the fixed housing 13. It is set inside the fixed housing 13 to limit the sliding stroke of the sliding column 15 and to provide a support point for the spring 16. The limiting disc 17 is set inside the fixed housing 13. A limiting groove 18 is opened inside the fixed housing 13. The outer wall of the limiting disc 17 is slidably connected to the inside of the limiting groove 18. The outer wall of the sliding column 15 is fitted with a spring 16. One end of the spring 16 is fixedly connected to the outer wall of the limiting disc 17, and the other end of the spring 16 is fixedly connected to the inner wall of the limiting groove 18.

[0036] Specifically, during the operation of the air flotation machine 2, when the air flotation machine 2 is inlet, the airflow with a certain pressure enters the inlet 11. The strong airflow thrust drives the sealing plug 12 to slide inside the inlet 11. The sealing plug 12 is connected to the sliding column 15. As the sealing plug 12 slides, the sliding column 15 also moves, thereby driving the limiting disc 17 fixed at one end of the sliding column 15 to slide inside the limiting groove 18. During this process, the sliding of the limiting disc 17 will compress the internal spring 16, causing the spring, which was originally closed, to move back to its original position. When the air intake channel is opened, the airflow can pass through smoothly, providing the gas required for the operation of the air flotation machine 2. When the air intake ends, the internal air pressure of the air flotation machine 2 gradually stabilizes, and the spring 16, which has lost the thrust of the airflow, begins to rebound. Its elastic restoring force drives the limiting disc 17 to return to its original position along the limiting groove 18. Then, the sliding column 15 pulls the sealing plug 12 back into the air intake port 11 to seal it, effectively preventing gas backflow, ensuring the stability of the internal gas environment of the air flotation machine 2, and preventing external impurities, moisture, etc. from entering and interfering with the processing process.

[0037] Working principle: When wastewater is treated by the flotation machine 2, the floating particles tend to stick to the inner wall of the flotation machine 2. At this time, the motor 6 can be started, and the motor 6 drives the transmission belt 3 to rotate. Then, the transmission belt 3 drives the connecting ring 9 to move, which drives the bottom scraper 10 to slide inside the flotation machine 2 to scrape off the particles stuck to the inner wall, avoid corrosion inside, and improve the overall strength.

[0038] In addition, during air intake, the airflow moves the sealing plug 12 to slide inside the air intake 11. Then, the sealing plug 12 moves the sliding column 15, causing the limiting disc 17 at one end to slide inside the limiting groove 18, compressing the internal spring 16, so that the airflow can pass through. Then, when the air intake ends, the spring 16 rebounds and causes the limiting disc 17 to return to its original position, pulling the sealing plug 12 back into the air intake 11 to seal it and prevent backflow.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
