Description

Technical Field

[0001] This utility model specifically relates to the field of membrane cleaning technology, and more specifically to a membrane cleaning machine for reverse osmosis membrane production. Background Technology

[0002] Reverse osmosis membranes are semi-permeable membranes used to separate and purify liquid mixtures. During the production process, various impurities may adhere to the membrane surface, such as unreacted monomers, additives, solvent residues, and dust from the air. These impurities can affect membrane performance, such as clogging membrane pores, reducing water flux, or affecting the membrane's retention of solutes. Residual impurities may also become a breeding ground for microorganisms. The growth and reproduction of microorganisms can cause biofouling of the membrane, thereby reducing its performance and lifespan. Therefore, reverse osmosis membranes need to be cleaned after production. Generally, deionized water or pretreated high-quality fresh water is used to rinse the membrane elements.

[0003] However, in practice, it has been noted that reverse osmosis membranes are generally formed by precipitating polymers in the membrane-forming solution through phase inversion. Therefore, liquid rinsing alone cannot fully clean the impurities on the surface of the reverse osmosis membrane. If rinsing alone is used, the reverse osmosis membrane will need to be rinsed for a long time, which will also affect the cleaning efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a membrane cleaning machine for reverse osmosis membrane production. Utilizing a rotatable cleaning sleeve, the reverse osmosis membrane can be rinsed from multiple angles, increasing the cleaning effect. Furthermore, the brushes located on the outer side of the rotating sleeve further enhance the cleaning effect on the reverse osmosis membrane, thereby improving the cleaning efficiency. This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A membrane cleaning machine for reverse osmosis membrane production includes a cleaning hood, in which fixed support tubes are symmetrically fixedly connected, and a rotating spray sleeve is movably connected to the outside of each of the fixed support tubes.

[0007] The rotating spray sleeve includes a single-opening sleeve with spray nozzles arranged in a ring array on the single-opening sleeve. Cleaning brushes are also fixedly connected to the outside of the single-opening sleeve in a ring array, and the spray nozzles and cleaning brushes are distributed alternately.

[0008] As a further technical solution of this utility model, the fixed support tube includes a hollow temporary storage tube, one end of which is fixedly connected to the cleaning hood, and the end of the hollow temporary storage tube connected to the cleaning hood is integrally provided with an extension connector, which extends through the cleaning hood to the side.

[0009] As a further technical solution of this utility model, the bottom of the hollow temporary storage tube is provided with a strip-shaped water outlet, and a single-opening sleeve is sleeved on the outside of the hollow temporary storage tube, and a sealing gasket is provided between the single-opening sleeve and the hollow temporary storage tube.

[0010] As a further technical solution of this utility model, the end of the single-opening sleeve is integrally provided with a mating toothed ring, and a drive gear is provided above the mating toothed ring;

[0011] A servo motor corresponding to the drive gear is fixedly connected to the side of the cleaning hood, and the end of the servo motor passes through the cleaning hood and is interference-fitted with the drive gear.

[0012] As a further technical solution of this utility model, the side of the cleaning cover is also provided with a water storage tank and a water supply pump, wherein one end of the water supply pump is connected to the water supply pump through a pipe, and the other end is fixedly connected to the extension connector through a pipe.

[0013] As a further technical solution of this utility model, the side of the water storage tank is also provided with an air compressor, and the air outlet of the water storage tank is connected to the water supply pump and the extension connector through a pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, a servo motor drives a single-opening sleeve to rotate outside a fixed support tube by meshing a drive gear and a gear ring. The spray nozzles arranged in a ring array on the outside of the single-opening sleeve, along with the cleaning brushes arranged in an alternating pattern, perform multiple cleanings on the reverse osmosis membrane. This method utilizes the impact force of the liquid and the friction force of the cleaning brushes to thoroughly clean the reverse osmosis membrane, thereby improving the cleaning effect.

[0016] This invention uses a hollow storage tube to fix the rotating spray sleeve, and the strip outlet at the bottom of the hollow storage tube ensures that the cleaning liquid is always sprayed downwards. The rotating single-opening sleeve and the strip outlet work together to change the spray direction of the cleaning liquid through the spray nozzle, thereby performing multi-angle cleaning and improving the cleaning effect.

Detailed Implementation

[0027] 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.

[0028] Please see Figure 1-8 This utility model provides a membrane cleaning machine for reverse osmosis membrane production, including a cleaning hood 1, in which fixed support tubes 6 are symmetrically fixedly connected, and a rotating spray sleeve 9 is movably connected to the outside of each of the fixed support tubes 6.

[0029] The rotating spray sleeve 9 includes a single-opening sleeve 91, on which spray nozzles 93 are arranged in a ring array. Cleaning brushes 94 are also fixedly connected in a ring array on the outer side of the single-opening sleeve 91. The spray nozzles 93 and cleaning brushes 94 are distributed alternately.

[0030] By adopting the above technical solution, the servo motor 7 drives the single-opening sleeve 91 to rotate outside the fixed support tube 6 through the meshing between the drive gear 8 and the mating gear ring 92. The spray nozzles 93 arranged in a ring array on the outside of the single-opening sleeve 91 and the cleaning brushes 94 arranged in an alternating pattern perform multiple cleaning of the reverse osmosis membrane. The reverse osmosis membrane can be thoroughly cleaned by utilizing the impact force of the liquid and the friction force of the cleaning brushes 94, thereby improving the cleaning effect of the reverse osmosis membrane.

[0031] Furthermore, the fixed support tube 6 includes a hollow temporary storage tube 61, one end of which is fixedly connected to the cleaning cover 1. The end of the hollow temporary storage tube 61 connected to the cleaning cover 1 is integrally provided with an extension connector 62, and the extension connector 62 extends through the cleaning cover 1 to the side.

[0032] More specifically, the bottom of the hollow temporary storage tube 61 is provided with a strip-shaped water outlet 63, and a single-opening sleeve 91 is sleeved on the outside of the hollow temporary storage tube 61, and a sealing gasket is provided between the single-opening sleeve 91 and the hollow temporary storage tube 61.

[0033] Furthermore, the end of the single-opening sleeve 91 is integrally provided with a mating gear ring 92, and a drive gear 8 is provided above the mating gear ring 92;

[0034] A servo motor 7 corresponding to the drive gear 8 is fixedly connected to the side of the cleaning cover 1, and the end of the servo motor 7 passes through the cleaning cover 1 and is interference-fitted with the drive gear 8.

[0035] By adopting the above technical solution, the rotating spray sleeve 9 is fixedly connected by the hollow temporary storage tube 61. Moreover, the strip-shaped water outlet 63 set at the bottom of the hollow temporary storage tube 61 can ensure that the cleaning liquid is always sprayed downwards. Furthermore, the rotating single-opening sleeve 91 and the strip-shaped water outlet 63 cooperate with each other, and the spray direction of the cleaning liquid is changed through the spray nozzle 93, thereby performing multi-angle cleaning and improving the cleaning effect.

[0036] Furthermore, the side of the cleaning hood 1 is also provided with a water storage tank 4 and a water supply pump 5, wherein one end of the water supply pump 5 is connected to the water supply pump 5 via a pipe, and the other end is fixedly connected to the extension connector 62 via a pipe.

[0037] Furthermore, an air compressor 3 is also provided on the side of the water storage tank 4, and the air outlet of the water storage tank 4 is connected to the water supply pump 5 and the extension connector 62 through a pipe.

[0038] More specifically, the air compressor 3 sends compressed gas into the hollow storage tube 61 through a pipeline, and at the same time, the water pump 5 sends the cleaning liquid inside the water tank 4 into the hollow storage tube 61.

[0039] More specifically, when the spray nozzle 93 on either side of the single-opening sleeve 91 is connected to the strip outlet 63, the airflow will spray the cleaning liquid through the strip outlet 63 and the spray nozzle 93 to clean the reverse osmosis membrane below the spray nozzle 93. At the same time, as the single-opening sleeve 91 rotates, the orientation of the spray nozzle 93 also changes, thereby cleaning the reverse osmosis membrane at a clear angle.

[0040] Furthermore, the rotating single-opening sleeve 91 will also cause the cleaning brush 94 to come into contact with the reverse osmosis membrane, improving the cleaning effect on the reverse osmosis membrane.

[0041] More specifically, the cleaning hood 1 is equipped with a transmission structure to move the reverse osmosis membrane, and the bottom of the transmission structure is provided with a liquid collection tank to collect the cleaning liquid. The collected cleaning liquid returns to the water storage tank 4 through a pipe fixedly connected to the bottom of the liquid collection tank.

[0042] Furthermore, an electrical control box 2 is fixedly connected to the side of the cleaning hood 1, and the electrical control box 2 is electrically connected to the air compressor 3, the water supply pump 5 and the servo motor 7 through wires.

[0043] The working principle of this utility model is as follows: In use, the transmission structure in the cleaning hood 1 first drives the reverse osmosis membrane to pass through the inside of the cleaning hood 1. At this time, the air compressor 3 and the water supply pump 5 respectively send compressed air and cleaning liquid into the hollow storage tube 61. The servo motor 7 drives the single-opening sleeve 91 to rotate on the outside of the hollow storage tube 61 through the transmission connection between the drive gear 8 and the mating gear ring 92. When the spray nozzle 93 on any side of the single-opening sleeve 91 is connected to the strip outlet 63, the airflow will spray the cleaning liquid through the strip outlet 63 and the spray nozzle 93 to clean the reverse osmosis membrane below the spray nozzle 93. At the same time, the cleaning brush 94 on the single-opening sleeve 91 follows the rotation of the single-opening sleeve 91 and comes into contact with the reverse osmosis membrane to clean it, thereby improving the cleaning effect of the reverse osmosis membrane. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.
