Description

Technical Field

[0001] The utility model relates to the technical field of membrane cleaning equipment, in particular to a novel corrugated array membrane cleaning equipment. Background Art

[0002] In the technical field of water resource treatment and reuse, the application of membrane technology is becoming more and more extensive, especially the membrane bioreactor (MBR) technology, which combines the two major technologies of biological treatment and membrane separation, and significantly improves the water treatment efficiency. With the advancement of technology, the types of membranes are becoming more and more abundant, from flat membranes, tubular membranes to curtain membranes and other forms, and each membrane structure has its specific application scenario. In recent years, curtain membranes, as an innovative membrane structure, have been widely used in MBR technology. However, with this comes an urgent need for curtain membrane cleaning technology.

[0003] Traditional MBR membrane cleaning methods mainly include physical cleaning and chemical cleaning. Physical cleaning mainly relies on mechanical force to remove pollutants from the membrane surface, but this method is more effective for membranes with less pollution, but has limited effect on heavily polluted membranes. Chemical cleaning is to add specific chemical agents to the cleaning solution to decompose or dissolve pollutants through chemical reactions, but this method may not only introduce new sources of pollution and cause secondary pollution problems, but also has a cumbersome operation process and low efficiency. Ultrasonic cleaning, as a type of physical cleaning, has a certain application basis in other membrane separation technologies, but due to the particularity of the curtain MBR membrane structure, related research and practice are still relatively small, and it is often difficult to achieve the ideal cleaning effect using ultrasonic cleaning alone.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides a novel corrugated array membrane cleaning device, comprising: a PLC controller, which is used to accurately control the operation of various components of the device; an ultrasonic generator and a transducer, which are used to generate high-frequency ultrasonic signals and convert them into mechanical vibrations to act on a diaphragm; a voltage-stabilized power supply, which provides stable power support for the device; an electromagnetic valve and a time-controlled switch, which control the flow of a cleaning liquid and the operating time of the device; a cleaning tank, which is used to place the diaphragm to be cleaned; wherein the cleaning tank comprises a tank body, ultrasonic tubes are arranged on both sides of the tank body, the ultrasonic tubes are connected to the ultrasonic generator, and a plurality of ultrasonic tube nozzles are arranged on the radial end faces of the ultrasonic tubes; ladders are arranged on both sides of the tank body, anti-skid platforms are arranged at the tops of both sides of the tank body, and guardrails are arranged on both sides of the anti-skid platform.

[0007] Furthermore, both side walls of the trough body and the bottom of the trough body are provided with reinforcing ribs.

[0008] Furthermore, a ladder guard cage is provided on one side of the ladder.

[0009] Furthermore, the reinforcing rib is made of a metal square tube.

[0010] Furthermore, a liquid outlet is provided on the side wall of the tank body.

[0011] Beneficial effects of the utility model: The equipment is designed to extend the service life of the membrane and improve its performance through efficient cleaning, simplified operation and meeting the actual needs of remote areas. The PLC controller accurately controls the coordinated work of various components to ensure the stability and automation of the cleaning process, thereby greatly reducing the complexity and uncertainty of manual operation and improving the consistency of cleaning efficiency and effect. The ultrasonic generator and transducer work together to produce high-frequency vibrations that can effectively break the adhesion of pollutants to the membrane and achieve deep cleaning of the membrane. Compared with traditional chemical cleaning, this method is more environmentally friendly and harmless to the membrane material. It is equipped with a voltage-stabilized power supply to provide continuous and stable power support for the entire set of equipment to avoid equipment failure or performance degradation caused by voltage fluctuations.

[0031] In the context of increasingly scarce water resources, the application of membrane technology in water treatment has become increasingly important. However, membrane contamination has seriously affected the service life and performance of the membrane. Especially in remote areas such as rural areas, due to the lack of cleaning equipment and technicians, membrane cleaning has become an urgent problem to be solved. To solve this problem, the utility model proposes a new type of corrugated array membrane cleaning device, which aims to extend the service life and improve the performance of the membrane through efficient cleaning, simplified operation and meeting the actual needs of remote areas.

[0032] like Figures 1 to 6 As shown, the corrugated array membrane cleaning equipment described in the utility model is mainly composed of a PLC controller, an ultrasonic generator and transducer, a voltage-stabilized power supply, an electromagnetic valve and a time-controlled switch, a cleaning tank, and a cleaning gun head, forming a set of sophisticated and efficient cleaning systems. The PLC controller is used to accurately control the operation of each component of the equipment; the ultrasonic generator and transducer are used to generate high-frequency ultrasonic signals and convert them into mechanical vibrations to act on the diaphragm; the voltage-stabilized power supply provides stable power support for the equipment; the electromagnetic valve and the time-controlled switch control the flow of the cleaning liquid and the running time of the equipment; the cleaning tank is used to place the diaphragm to be cleaned; wherein, the cleaning tank includes a tank body 1, and ultrasonic tubes 2 are provided on both sides of the tank body 1, and the ultrasonic tubes 2 are connected to the ultrasonic generator, and a plurality of ultrasonic tube nozzles 3 are provided on the radial end face of the ultrasonic tube 2; ladders 4 are provided on both sides of the tank body 1, and a ladder cage 9 is provided on one side of the ladder 4. Anti-skid platforms 5 are provided at the top of both sides of the tank body 1, and guardrails 7 are provided on both sides of the anti-skid platform 5. Reinforcing ribs 8 are provided on both sides of the tank wall of the tank body 1 and the bottom of the tank body. The reinforcing rib 8 is made of a metal square tube. A liquid outlet 10 is provided on the side wall of the tank body 1. Figure 1 As shown, the ladder 4 on one side of the trough body, the ladder cage 9 and the anti-slip platform 5 on the top are not shown in the figure. The voltage-stabilized power supply 13 is arranged on the side of the trough body 1, and the ultrasonic generator 11 is connected to the voltage-stabilized power supply 13; the solenoid valve 14 is arranged at the top end of the ultrasonic tube 2, and the transducer 12 is connected to the solenoid valve 14.

[0033] In this embodiment, the PLC controller, as the "brain" of the whole set of equipment, accurately controls the coordinated work of various components to ensure the stability and automation of the cleaning process, thereby greatly reducing the complexity and uncertainty of manual operation and improving the cleaning efficiency and consistency of the effect. The ultrasonic cleaning technology of the equipment is one of its core highlights. The high-frequency vibration generated by the joint work of the ultrasonic generator and the transducer can effectively break the adhesion of pollutants to the membrane and achieve deep cleaning of the membrane. Compared with traditional chemical cleaning, this method is more environmentally friendly and harmless to the membrane material.

[0034] In order to ensure the stable operation of the equipment in areas with unstable electricity, this embodiment is specially equipped with a voltage-stabilized power supply to provide continuous and stable power support for the entire equipment to avoid equipment failure or performance degradation caused by voltage fluctuations. The introduction of solenoid valves and time-controlled switches enables the flow of cleaning liquid and cleaning time to be precisely controlled, which not only improves the cleaning efficiency, but also ensures the stability and reliability of the cleaning quality.

[0035] The cleaning tank is made of high-quality materials that are corrosion-resistant and high-temperature-resistant, ensuring protection of the diaphragm during the cleaning process. At the same time, its design also fully considers the convenience of use and portability.

[0036] like Figure 6 In the embodiment shown, a plurality of cleaning gun heads are specially provided on the ultrasonic tube 2, and these cleaning gun heads are ultrasonic tube nozzles 3. The spraying directions of the two ultrasonic tube nozzles 3 are at an angle of 90°, which can ensure that each diaphragm can be cleaned evenly and effectively. At the same time, the ultrasonic template has a moderate amplitude, which can ensure the cleaning effect without causing damage to the diaphragm.

[0037] like Figure 4 As shown, the corrugated array membrane cleaning device of the utility model is composed of key components such as a PLC controller, an ultrasonic generator and transducer, a voltage-stabilized power supply, a solenoid valve and a time-controlled switch, and a cleaning tank. These components perform their respective functions and cooperate with each other to jointly complete the efficient process of membrane cleaning.

[0038] Before using this equipment, users need to do some preparation. First, users need to remove the corrugated array membrane to be cleaned from the water treatment system. During the disassembly process, users need to carefully check the degree of contamination of the diaphragm to provide a reference for the subsequent selection of appropriate cleaning fluid and setting of cleaning parameters. This step is crucial because different degrees of contamination may require different cleaning strategies and times. At the same time, users also need to check whether the various components of the equipment are intact, such as the PLC controller, ultrasonic generator and transducer, stabilized power supply, etc., to ensure that the equipment is in good working condition.

[0039] Next, the user places the diaphragm in the cleaning tank and adds an appropriate amount of cleaning solution. The choice of cleaning solution is crucial because it directly affects the cleaning effect and the safety of the diaphragm. The user needs to determine the type and concentration of the cleaning solution based on the material of the diaphragm, the nature of the contaminants, and the cleaning requirements. The appropriate cleaning solution can effectively dissolve or disperse the contaminants, thereby improving the cleaning effect.

[0040] After confirming that all preparations are correct, the user can start the PLC controller of the equipment and enter the parameter setting interface. The PLC controller, as the "brain" of the equipment, is responsible for accurately controlling the operation of each component. The user can set the appropriate cleaning time and ultrasonic power and other key parameters according to the degree of contamination of the diaphragm, the properties of the cleaning fluid and actual needs. The setting of these parameters will directly affect the cleaning effect and efficiency.

[0041] When the equipment is started, the ultrasonic generator starts working and generates high-frequency ultrasonic signals. These signals are then transmitted to the ultrasonic transducer and converted into powerful mechanical vibrations. These vibrations act directly on the cleaning liquid in the cleaning tank and the surface of the diaphragm, effectively destroying the adhesion between the contaminants and the surface of the diaphragm through physical effects, thereby achieving deep cleaning. Compared with traditional chemical cleaning methods, ultrasonic cleaning does not require the use of chemical agents, is more environmentally friendly and does not damage the membrane material.

[0042] In the cleaning process, the solenoid valve plays a key role. It will open or close accurately according to the instructions of the PLC controller to control the flow of the cleaning liquid. This function allows the cleaning liquid to circulate, discharge and replace in the cleaning tank, ensuring the continuity and effectiveness of the cleaning process. At the same time, the time switch is responsible for accurately controlling the operation and stop of the equipment according to the time set by the user. This function allows the cleaning process to be completed within the predetermined time, avoiding the problem of affecting the cleaning effect due to too long or too short time.

[0043] As an important part of the equipment, the cleaning tank is also of great importance in terms of its material and design. The cleaning tank of the utility model is made of high-quality materials that are corrosion-resistant and high-temperature-resistant, and can accommodate an appropriate amount of cleaning liquid and ensure that the diaphragm will not be damaged or contaminated during the cleaning process. At the same time, its design also fully considers ease of use and portability, making it convenient for users to carry and install in actual operations.

[0044] Through the synergistic effect of the above-mentioned components, the corrugated array membrane cleaning device of the utility model realizes deep cleaning of the membrane. The user only needs to perform simple operation settings, and the device can automatically complete the entire cleaning process. This feature greatly improves work efficiency and cleaning effect, making membrane cleaning easier and more convenient.

[0045] When using this equipment, users need to strictly follow the operation manual and regularly maintain and service the equipment to ensure its long-term stable operation. In addition, users also need to pay attention to the safe use of the equipment to avoid accidents during use.

[0046] The utility model of the corrugated array membrane cleaning device has brought great convenience and benefits to water treatment applications in rural and other remote areas with its high efficiency, convenience and environmental protection. At the same time, its innovative design and efficient technical means have also solved many problems existing in traditional membrane cleaning methods.

[0047] In summary, this corrugated array membrane cleaning device is not only small in size, light in weight, easy to carry and transport, but also easy to operate. The one-button start and intuitive LCD display design greatly reduce the operating threshold. At the same time, its efficient and environmentally friendly cleaning method is also in line with the current trend of sustainable development. Through the above comprehensive design and optimization, the corrugated array membrane cleaning device of the utility model not only solves the problem of membrane cleaning in remote areas, but also makes positive contributions to water resource protection and sustainable development with its high efficiency, portability, ease of use and environmental protection.

[0048] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution disclosed in the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work should be included in the scope of protection of the utility model.
