Description

Technical Field

[0001] This application belongs to the technical field of reverse osmosis membrane cleaning, and particularly relates to a reverse osmosis membrane cleaning device. Background Art

[0002] A reverse osmosis membrane is an artificial semi-permeable membrane with certain characteristics made by simulating a biological semi-permeable membrane, and is the core component of reverse osmosis technology. The principle of reverse osmosis technology is that under the action of a pressure higher than the osmotic pressure of the solution, other substances are separated from water based on the fact that they cannot pass through the semi-permeable membrane. The membrane pore diameter of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic substances, etc. in water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process, convenient operation, etc.

[0003] After reverse osmosis is used, many impurities will adhere to its surface. At this time, the impurities on its surface need to be cleaned for reuse. Existing reverse osmosis membrane cleaning devices all mix water and cleaning agents into a cleaning solution to clean it. However, the requirements for water during reverse osmosis membrane cleaning are extremely high, and impurities in the water are easily blocked in the membrane pores. In addition, there are also certain requirements for the temperature and pressure of the system environment during cleaning. Summary of the Invention

[0004] This application provides a reverse osmosis membrane cleaning device to solve the technical problem that water impurities are easily blocked in the membrane pores during reverse osmosis membrane cleaning.

[0005] The technical solution adopted in this application is as follows:

[0006] A reverse osmosis membrane cleaning device includes a base. It is characterized in that: a cleaning box is fixedly installed at the upper end of the base. Guide rails with symmetrical positions are arranged on the opposite inner walls of the cleaning box, and a driving component slidably matched with the guide rails is installed on the guide rails. The driving component is fixedly connected with a cleaning component. The cleaning component includes a spray pipe and a mounting rack arranged side by side between the driving components. A number of spray nozzles are evenly arranged on the circumferential surface of the spray pipe in a direction perpendicular to the guide rails. A number of flexible brushes are evenly arranged on the lower end surface of the mounting rack in a direction perpendicular to the guide rails. A clamping component installed at the bottom of the cleaning box is arranged below the cleaning component.

[0012] Optionally, a universal wheel locking assembly is provided at the lower end of the base, including a universal wheel, a brake block, and a spring. The brake block is connected to the universal wheel bracket through a pin shaft. One end of the spring is fixedly arranged at the lower end of the base, and the other end is connected to the brake block.

[0013] Due to the adoption of the above technical solutions, the beneficial effects obtained by this application are as follows:

[0014] 1. One end of the spray pipe is connected to the water tank, and a plurality of spray nozzles are distributed at the other end. The spray nozzles are arranged obliquely at a certain angle. At the same time, in cooperation with the driving assembly, the clamping assembly, etc., the membrane can be cleaned at multiple angles, avoiding cleaning blind spots.

[0029] A reverse osmosis membrane cleaning device includes a base 1, and is characterized in that: a cleaning box 2 is fixedly installed at the upper end of the base 1. Guide rails with symmetric positions are arranged on the opposite inner walls of the cleaning box 2, and a driving component 3 slidably matched with the guide rails is installed on the guide rails. The driving component 3 is fixedly connected to a cleaning component 4. The cleaning component 4 includes a spray pipe 41 installed in parallel between the driving components 3 and a mounting frame 42. A plurality of spray nozzles 411 are evenly arranged on the circumferential surface of the spray pipe 41 in a direction perpendicular to the guide rails. A plurality of flexible brushes 421 are evenly arranged on the lower end surface of the mounting frame 42 in a direction perpendicular to the guide rails. A clamping component 6 installed at the bottom of the cleaning box 2 is arranged below the cleaning component 4. The clamping component 6 includes a plurality of clamping rollers arranged horizontally in parallel. One end of the clamping roller is sleeved in a rotating shaft 64, and the opposite end is sleeved in a clamping frame 65. The rotating shaft 64 is connected to the driving shaft of a first motor, and the power shaft of the clamping frame 65 is connected to the driving shaft of a second motor through a lead screw.

[0030] Further, the driving component 3 includes an electric telescopic rod 31 fixedly arranged on the inner wall of the cleaning box 2, and a slider 32 fixedly connected to the electric telescopic rod 31. The side wall of the slider 32 is fixedly connected to the cleaning component 4.

[0031] Further, the cleaning assembly 4 includes a spray pipe 41 installed side by side on the side wall of the slider 32 and a mounting bracket 42. One end of the spray pipe 41 is connected to the water tank 7 through a pipeline, and a plurality of spray nozzles 411 are evenly arranged at the opposite end. A plurality of flexible brushes 421 are installed at one end of the mounting bracket 42 facing the support frame 5.

[0032] Further, the flexible brush 421 is made of wear-resistant flexible material, and the length and density of the bristles can be adjusted. The spray nozzles 411 are arranged obliquely on the spray pipe 41 at a certain angle.

[0033] By adopting the above technical solutions, the base 1 is made of high-strength material, providing stable support for the entire device. It can withstand the vibration and external forces generated during the cleaning process of the device, ensuring the stability of the device. The cleaning tank 2 is fixedly installed above the base 1, and the box body is made of corrosion-resistant material to prevent the chemical components in the cleaning liquid from corroding the device. The cleaning tank 2 is a cuboid structure, and its interior is divided into multiple functional areas, which are respectively used to install the drive assembly 3, the cleaning assembly 4, and the assembly for supporting and clamping the reverse osmosis membrane. Guide rails are symmetrically arranged on the inner walls of the short ends of the cleaning tank 2, and the guide rails are slidably matched with the drive assembly 3, enabling the cleaning assembly 4 to move in the box body along the guide rails, thereby achieving a comprehensive cleaning of the reverse osmosis membrane.

[0034] The drive assembly 3 includes an electric telescopic rod 31 and a slider 32. One end of the electric telescopic rod 31 is fixedly installed on the inner wall of the cleaning tank 2, and the other end is fixedly connected to the slider 32. By controlling the telescopic movement of the electric telescopic rod 31, the slider 32 can slide back and forth on the guide rail. The side wall of the slider 32 is fixedly connected to the cleaning assembly 4, and the cleaning assembly 4 includes a spray pipe 41, spray nozzles 411, and flexible brushes 421. The spray pipes 41 are evenly distributed on both sides of the slider 32. One end of the spray pipe 41 is connected to the water tank 7 through a pipeline, and a plurality of spray nozzles 411 are installed at the other end, which are used to evenly spray the cleaning liquid on the surface of the reverse osmosis membrane.

[0035] The spray nozzles 411 are designed to be arranged obliquely at a certain angle, aiming to ensure that the cleaning liquid can be sprayed onto the surface of the membrane at different angles, avoiding cleaning blind spots in a single direction. The number and distribution of the spray nozzles 411 are optimized so that the cleaning liquid can cover every part of the reverse osmosis membrane, ensuring thorough cleaning. The spraying angle of the spray nozzles 411 can be adjusted according to the size and shape of different reverse osmosis membranes to meet different cleaning requirements.

[0036] The flexible brush 421 is installed below the spray pipe 41 and is made of wear-resistant flexible material. The length and density of the bristles can be adjusted according to the actual situation to adapt to the cleaning of different types of reverse osmosis membranes. The function of the flexible brush 421 is to cooperate with the spray pipe 41 to physically wipe the membrane surface, removing some stubborn dirt or deposits to ensure a more significant cleaning effect. Through the movement of the electric telescopic rod 31, the flexible brush 421 can cover the entire membrane surface for cleaning.

[0037] In addition, several support frames 5 are provided at the bottom of the cleaning tank 2. These support frames 5 are sleeved outside the clamping assembly 6 through bearings and are used to support the stability of the reverse osmosis membrane during the cleaning process. The installation position and quantity of the support frames 5 are optimized according to the internal space of the cleaning tank to ensure that, without affecting the movement of the cleaning components, the reverse osmosis membrane is supported to the greatest extent and prevented from shifting during the cleaning process.

[0038] Furthermore, the clamping assembly 6 includes a central wheel 61, a planet carrier 62, several planet wheels 63, and a rotating shaft 64 that meshes internally with the planet wheels 63. It also includes a clamping frame 65 connected to the screw nut. One end of the planet carrier 62 is connected to the output shaft of the motor, and the other end opposite thereto is fixedly connected to the planet wheels 63.

[0039] By adopting the above technical solution, the clamping assembly 6 firmly fixes the reverse osmosis membrane inside the cleaning tank 2 through the coordinated action of the central wheel 61 and the rotating shaft 64, and at the same time, the rotation of the membrane can be realized, thereby further improving the cleaning efficiency.

[0040] Specifically, the central wheel 61 is installed on one side inside the cleaning tank 2 and is connected to the planet carrier 62 through the rotating shaft 64. One end of the planet carrier 62 is connected to the output shaft of the motor, and the other end is meshed with the rotating shaft 64 through several planet wheels 63. By driving the planet carrier 62 to rotate by the motor, the reverse osmosis membrane can slowly rotate around its axis. The purpose of this rotational design is to ensure that each surface of the membrane can uniformly receive the cleaning liquid sprayed by the spray pipe 41 and the wiping of the flexible brush 421, thereby achieving 360-degree dead-angle-free cleaning.

[0041] The clamping frame 65 is connected to the planet carrier 62 through the screw nut. The screw nut can adjust the tightness of the clamping frame 65, thereby adjusting the clamping according to reverse osmosis membranes of different sizes. The material of the clamping frame 65 is made of high-strength alloy, which can withstand a certain amount of external force to ensure that the membrane does not shift or loosen during the cleaning process.

[0042] In addition, the design of the clamping assembly 6 also considers the convenience of the equipment. When it is necessary to replace or maintain the reverse osmosis membrane, the operator only needs to rotate the screw to easily unlock the clamping frame 65 and remove the membrane. This design greatly improves the maintenance efficiency of the equipment and reduces the operation time.

[0043] The water tank 7 is installed on the top of the cleaning box 2, and its capacity is designed according to the cleaning requirements. The water tank 7 is connected to the cleaning component 4 inside the cleaning box 2 through a water pump. The function of the water pump is to send the water in the water tank 7 into the spray pipe 41 for cleaning. In addition, the water tank 7 is also equipped with a filter, which is connected to the water tank 7 through a water pipe and can effectively remove impurities in the water to ensure the cleanliness of the water entering the spray pipe 41. This design not only improves the cleaning effect of the equipment, but also extends the service life of the reverse osmosis membrane. The water in the water tank 7 can be replaced or a cleaning agent can be added according to the actual cleaning requirements to further enhance the cleaning ability and avoid membrane pore blockage caused by water quality problems.

[0044] Furthermore, a locking assembly for the universal wheels 8 is provided at the lower end of the base 1, including the universal wheels 8, a brake block and a spring. The brake block is connected to the bracket of the universal wheel 8 through a pin shaft. One end of the spring is fixedly arranged at the lower end of the base 1, and the other end is connected to the brake block.

[0045] To improve the mobility and applicability of the equipment, the base 1 part is improved by adding a locking assembly for the universal wheels 8. The universal wheels 8 are installed at the four corners of the base 1. Through the design of the universal wheels 8, the equipment can be easily moved in different working places and meet the requirements of various space layouts. The brake block is connected to the bracket of the universal wheel 8 through a pin shaft. When it is necessary to fix the equipment at a certain position for cleaning, the operator only needs to step on the brake block. The brake block presses the universal wheel 8 under the action of the spring to prevent it from rotating, so as to firmly lock the equipment on the ground. This locking mechanism is not only simple and easy to use, but also can ensure the stability of the equipment during the cleaning process and avoid affecting the cleaning effect due to the movement or vibration of the equipment. After the cleaning work is completed, the operator only needs to lift the brake block, and the universal wheel 8 will return to the free state, and the equipment can be moved to the required position again.

[0046] Furthermore, an observation window is also provided on the top of the cleaning box 2. The observation window is connected to the box body through a hinge, and the hinge is fixed to the box body by bolts.

[0047] By adopting the above technical solutions, in order to facilitate the operator to monitor the cleaning process in real time, the design of the observation window is added in this embodiment. A transparent observation window is provided on the top of the cleaning box 2, which is connected to the box body through a hinge, and the hinge is fixed to the cleaning box 2 by bolts. The operator can directly observe the cleaning situation of the reverse osmosis membrane through the observation window and judge whether the cleaning is thorough.

[0048] The observation window is made of corrosion-resistant materials and can withstand the high-temperature and high-pressure environment during the cleaning process while maintaining good transparency. Through the design of the observation window, the operator can understand the cleaning progress without frequently opening the box body, which greatly improves the convenience and safety of the operation.
