Description

Technical Field

[0001] This utility model relates to the field of cleaning flow control technology, and in particular to a flow regulation device for the reverse osmosis membrane cleaning process. Background Technology

[0002] With increasingly stringent water quality requirements for industrial production and domestic use, reverse osmosis membrane technology, due to its high separation efficiency, has been widely applied in water treatment, seawater desalination, and food and beverage processing. During long-term operation, reverse osmosis membranes are susceptible to contaminant adhesion, leading to decreased membrane flux and reduced desalination rate. Therefore, regular cleaning and maintenance are necessary to restore their performance. During cleaning, the flow rate control of the cleaning solution has a crucial impact on the cleaning effect and membrane lifespan. An appropriate flow rate ensures effective removal of contaminants while preventing irreversible damage to the membrane due to excessive flow. Therefore, developing a highly efficient and precise flow rate regulation device for reverse osmosis membrane cleaning has become an important direction for improving the efficiency of reverse osmosis membranes and reducing operating costs.

[0003] Shortcomings of existing technology:

[0004] 1) Most existing reverse osmosis membrane cleaning equipment uses fixed flow rate or manual valve adjustment to control the cleaning fluid flow rate. Fixed flow rate mode cannot be flexibly adjusted according to the fouling degree and material characteristics of different membrane elements, which can easily lead to insufficient or excessive cleaning; manual valve adjustment has the problems of low adjustment accuracy and cumbersome operation, which makes it difficult to meet the needs of modern fine cleaning operations, resulting in low cleaning efficiency and potentially affecting the service life of reverse osmosis membranes due to improper flow control.

[0005] 2) In most traditional cleaning equipment, the reverse osmosis membrane is fixed in its structural design, and the cleaning solution can only wash the membrane surface from a single direction or a limited angle. This results in uneven cleaning of the membrane surface, creating cleaning blind spots, and making it difficult to completely remove contaminants. At the same time, the equipment's sealing performance and structural stability are poor, making it prone to cleaning solution leakage during the cleaning process. This not only pollutes the environment but also wastes resources. Shaking or displacement of the equipment during operation can also affect the accuracy of flow regulation, increase the risk of equipment failure, and reduce the reliability and continuity of cleaning operations. Utility Model Content

[0006] The purpose of this invention is to solve the problems of inaccurate flow regulation of cleaning fluid, uneven cleaning, and poor equipment sealing and stability in the existing technology, and to propose a flow regulation device for the reverse osmosis membrane cleaning process.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a flow regulating device for reverse osmosis membrane cleaning process, comprising a mounting frame, a motor fixedly connected to the top of the mounting frame, and a rotating mechanism provided at the output end of the motor; the rotating mechanism includes a gear, a gear ring meshing with the outer wall of the gear, a rotating ring rotatably connected to the outer surface of the gear ring, a set of placement cylinders fixedly inserted inside the gear ring, an installation insert ring fixedly connected to the outer wall of the set of placement cylinders, and a housing sealed and rotatably fitted on opposite sides of the rotating ring and the installation insert ring.

[0008] Preferably, the outer surface of the housing is threaded with a connecting sleeve, and a sealing door is fixedly installed on the outer surface of the connecting sleeve.

[0009] Preferably, the outer wall of the rotating ring is fixedly connected to a connecting pipe, and one end of the connecting pipe is fixedly connected to an adjusting mechanism.

[0010] Preferably, the adjustment mechanism includes an installation tube, the outer wall of which is fixedly connected to a flow guide chamber, and the outer wall of the flow guide chamber is fixedly connected to a connecting member.

[0011] Preferably, the outer wall of the connecting member is fixedly connected to a flow-limiting tube, and a sliding sealing plug is slidably disposed inside the flow-limiting tube.

[0012] Preferably, the outer surface of the sliding sealing plug is fixedly connected to the output end of the filter hole, and the opposite sides of the connecting member and the flow limiting tube are provided with electric telescopic rods.

[0013] Preferably, a flow guide plug is fixedly connected to the inner wall of the flow guide chamber, and an external flange pipe is fixedly connected to the bottom of the flow limiting pipe.

[0014] Preferably, a first connecting bracket is mounted on the outer surface of the mounting bracket, a second connecting bracket is fixedly mounted on the top of the first connecting bracket, and a third connecting bracket is fixedly mounted on the inner top of the mounting bracket.

[0015] Preferably, the outer wall of the connecting pipe is fixedly connected to the top of the second connecting bracket, and the top of the third connecting bracket is rotatably connected to the outer wall of the outer shell.

[0016] Preferably, the output end of the motor is fixedly connected to the outer surface of the gear, and the outer wall of the housing is fixedly connected to a sewage discharge pipe.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] 1. In this utility model, the accuracy and efficiency of the cleaning operation are greatly improved by the flow adjustment mechanism and the rotating cleaning structure. The electric telescopic rod drives the sliding sealing plug to slide flexibly in the flow limiting tube, which can quickly and accurately adjust the flow rate of the cleaning solution according to the actual cleaning needs of the reverse osmosis membrane. Compared with the fixed flow rate or coarse adjustment method of traditional equipment, it can adapt to the cleaning scenarios of reverse osmosis membranes with different levels of pollution and different materials. At the same time, the motor drives the gear and gear ring transmission to make the placement cylinder for placing the reverse osmosis membrane rotate continuously, breaking the limitation of the membrane being fixed in the traditional cleaning equipment. This allows the cleaning solution to rinse the membrane surface in all directions without dead angles, significantly enhancing the cleaning effect, reducing the problem of secondary pollution caused by incomplete local cleaning, and effectively improving the cleaning efficiency.

[0019] 2. In this utility model, the sealing structure and support design provide a guarantee for the stable operation and convenient maintenance of the device.

The first connecting bracket, the second connecting bracket, and the third connecting bracket cooperate with each other to enhance the stability of the overall structure of the device, prevent shaking or displacement during operation, and ensure the accuracy and reliability of flow regulation. In addition, the setting of the sewage discharge connecting pipe facilitates the rapid discharge of sewage after cleaning, which is convenient for cleaning and maintenance of the device and ensures that the equipment can operate continuously and efficiently.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1: Please refer to the attached document. Figure 1 -Appendix Figure 6 As shown, this utility model provides a flow regulation device for the reverse osmosis membrane cleaning process, including a mounting frame 1. A motor 2 is fixedly connected to the top of the mounting frame 1, and a rotating mechanism 3 is provided at the output end of the motor 2. The rotating mechanism 3 includes a gear 301, a gear ring 302 meshing with the outer wall of the gear 301, a rotating ring 303 rotatably connected to the outer surface of the gear ring 302, a set of placement cylinders 305 fixedly inserted inside the gear ring 302, an installation insert ring 306 fixedly connected to the outer wall of the set of placement cylinders 305, a housing 307 sealingly and rotatably fitted on the opposite sides of the rotating ring 303 and the installation insert ring 306, a connecting sleeve 4 threaded on the outer surface of the housing 307, and a sealing door 5 fixedly installed on the outer surface of the connecting sleeve 4.

[0030] The overall effect of embodiment 1 is as follows: after the motor 2 starts, it drives the gear 301 to rotate. Through the meshing transmission between the gear 301 and the gear ring 302, the gear ring 302 drives the placement cylinder 305 to rotate. The placement cylinder 305 is used to place the reverse osmosis membrane. This rotation allows the reverse osmosis membrane to be fully flushed by the cleaning solution during the cleaning process, improving the cleaning effect. The outer shell 307, the rotating ring 303, and the mounting ring 306 are sealed and rotated together. With the threaded connection between the sealing door 5 and the connecting sleeve 4, a closed space is formed, which effectively prevents the cleaning solution from leaking and ensures that the cleaning work is carried out safely and stably. At the same time, the sealing door 5 is easy to open and close, making it convenient for staff to place and remove the reverse osmosis membrane in the placement cylinder 305.

[0031] Example 2: Please refer to the attached document. Figure 1 -Appendix Figure 6 As shown, the outer wall of the rotating ring 303 is fixedly connected to a connecting pipe 6, and one end of the connecting pipe 6 is fixedly connected to an adjusting mechanism 7. The adjusting mechanism 7 includes an installation pipe 701, the outer wall of the installation pipe 701 is fixedly connected to a flow guide chamber 702, the outer wall of the flow guide chamber 702 is fixedly connected to a connecting member 703, the outer wall of the connecting member 703 is fixedly connected to a flow limiting pipe 704, a sliding sealing plug 705 is slidably arranged inside the flow limiting pipe 704, and the outer surface of the sliding sealing plug 705 is fixedly connected to the output end of a filter hole 706. Electric telescopic rods 707 are opened on opposite sides of the connecting member 703 and the flow limiting pipe 704. A flow guide plug 708 is fixedly connected to the inner wall of the flow guide chamber 702, and an external flange pipe 709 is fixedly connected to the bottom of the flow limiting pipe 704.

[0032] The overall effect of Embodiment 2 is as follows: the cleaning fluid flows into the connecting pipe 6 through the regulating mechanism 7. In the flow guide chamber 702, the flow guide plug 708 guides the cleaning fluid to be evenly dispersed into the connecting member 703. By controlling the extension and retraction of the electric telescopic rod 707, the sliding sealing plug 705 can be pushed to slide in the flow limiting pipe 704, changing the flow area of ​​the flow limiting pipe 704, thereby achieving precise adjustment of the cleaning fluid flow rate. The filter holes 706 on the outer surface of the sliding sealing plug 705 can filter the cleaning fluid to prevent impurities from entering the subsequent pipeline and affecting the cleaning effect. The external flange pipe 709 facilitates connection with external pipelines, so that the adjusted cleaning fluid can be smoothly delivered to the reverse osmosis membrane for cleaning.

[0033] Example 3: Please refer to the attached document. Figure 1 -Appendix Figure 6As shown, a first connecting bracket 11 is installed on the outer surface of the mounting frame 1, a second connecting bracket 12 is fixedly installed on the top of the first connecting bracket 11, a third connecting bracket 13 is not fixedly installed on the inner top of the mounting frame 1, the outer wall of the connecting pipe 6 is fixedly connected to the top of the second connecting bracket 12, the top of the third connecting bracket 13 is rotatably connected to the outer wall of the outer shell 307, the output end of the motor 2 is fixedly connected to the outer surface of the gear 301, and a sewage discharge connecting pipe 8 is fixedly connected to the outer wall of the outer shell 307.

[0034] The overall effect of embodiment 3 is that the first connecting bracket 11, the second connecting bracket 12, and the third connecting bracket 13 cooperate with each other to enhance the stability of the overall structure of the device, ensuring that the rotating mechanism and the adjusting mechanism will not shake or shift during operation, and ensuring the accuracy and reliability of flow regulation. The structural design of the connecting pipe 6 being fixed to the second connecting bracket 12 and the outer shell 307 being rotatably connected to the third connecting bracket 13 ensures the stable delivery of cleaning fluid without affecting the normal operation of the rotating mechanism. After the reverse osmosis membrane is cleaned, the sewage in the outer shell 307 can be discharged through the sewage discharge connecting pipe 8, which facilitates the cleaning and subsequent use of the device.

[0035] Working Principle: During reverse osmosis membrane cleaning, the membrane to be cleaned is first placed in the placement cylinder 305. The outer casing 307 is sealed by the threaded connection between the sealing door 5 and the connecting sleeve 4, ensuring the device is in a sealed state. The motor 2 is started, and its output shaft drives the gear 301 to rotate. The gear 301 meshes with the gear ring 302, causing the gear ring 302 to rotate, which in turn drives the placement cylinder 305 to rotate. Simultaneously, the external cleaning liquid source is connected to the flow-limiting pipe 704 through the external flange pipe 709. The cleaning liquid enters the regulating mechanism 7. In the flow guide chamber 702, the flow guide plug 708 guides the cleaning liquid to disperse evenly. Subsequently, the cleaning liquid flows into the flow-limiting pipe 704 through the connecting piece 703. According to the actual cleaning requirements, the electric telescopic rod 707 is extended or retracted, pushing the sliding sealing plug 705 in the flow-limiting pipe 704. The internal sliding mechanism 4 changes the flow area of ​​the flow-limiting tube 704, enabling precise adjustment of the cleaning fluid flow rate. The adjusted cleaning fluid flows into the rotating ring 303 through the connecting pipe 6, and then into the outer shell 307. Since the placement cylinder 305 is in a rotating state, the reverse osmosis membrane is fully flushed by the cleaning fluid during the rotation process, improving the uniformity and thoroughness of the cleaning. Wastewater generated during the cleaning process will accumulate in the outer shell 307. After the cleaning work is completed, the wastewater discharge connecting pipe 8 is opened to discharge the wastewater for the next cleaning operation. The first connecting bracket 11, the second connecting bracket 12, and the third connecting bracket 13 work together to provide a stable support structure for the device, ensuring that the motor 2, the rotating mechanism 3, and the adjusting mechanism 7 remain stable during operation, ensuring the accuracy of flow regulation and the reliability of the cleaning work.

[0036] The wiring diagrams of the motor 2, sealing door 5, and electric telescopic rod 706 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the motor 2, sealing door 5, and electric telescopic rod 706 will not be explained in detail.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
