Technical Field

[0001] This utility model relates to the field of brewing technology, specifically to a self-cleaning reverse osmosis membrane structure for brewing Trichosanthes kirilowii wine. Background Technology

[0002] The water used for brewing Trichosanthes kirilowii wine typically contains various suspended particles, colloidal substances, and microorganisms such as bacteria and fungi. These impurities may trigger unnecessary fermentation or spoilage reactions during the brewing process. Therefore, reverse osmosis membranes are generally used to filter the water, blocking impurities and microorganisms from passing through, thus providing a sterile or low-bacterial high-quality water source for brewing Trichosanthes kirilowii wine and reducing the adverse effects of microorganisms on the brewing process and the quality of the wine.

[0003] However, over time, a lot of impurities and contaminants will adhere to the surface of the reverse osmosis membrane. If these deposits are not cleaned in time, they will seriously affect the filtration performance of the reverse osmosis membrane, thereby affecting the subsequent brewing effect of Trichosanthes kirilowii wine. Therefore, frequent maintenance and replacement are required. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a self-cleaning structure for the reverse osmosis membrane surface used in the brewing of Trichosanthes kirilowii wine, so as to solve the problem of excessive maintenance and replacement frequency of reverse osmosis membrane mentioned in the background art.

[0006] Preferably, the top surface of the circular membrane is provided with a guide groove from the middle to the edge, one end of the guide groove is connected to the entry end of the memory, and the depth of the guide groove gradually increases from the middle to the edge of the circular membrane.

[0007] Preferably, the top surface of the circular membrane has multiple annular grooves that diffuse outward from the center, and the annular grooves are connected to the guide groove.

[0008] Preferably, the memory includes a guide tube communicating with the reverse osmosis membrane module, a collection cylinder communicating with the bottom of the guide tube, a return pipe communicating between the bottom of the collection cylinder and the cylindrical shell, and the end of the return pipe connected to the cylindrical shell is located below the reverse osmosis membrane module.

[0009] Preferably, the inside of the collection tube is equipped with an intercepting membrane assembly, and control valves are installed on both the guide tube and the return tube.

[0010] Preferably, the cleaning brush includes a docking bracket mounted on a rotating shaft, a first cleaning brush inserted into the docking bracket, and a second cleaning brush integrally formed at the bottom of the first cleaning brush.

[0011] Preferably, the height of the first cleaning brush is adapted to the height of the annular membrane, and the bottom shape of the second cleaning brush is adapted to the top surface shape of the circular membrane.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1.

[0016] 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.

[0017] A self-cleaning reverse osmosis membrane structure for brewing Trichosanthes kirilowii wine, such as Figures 1-3 As shown, the device includes a cylindrical outer shell 1, inside which a reverse osmosis membrane module 2 is coaxially mounted. The reverse osmosis membrane module 2 is connected to the cylindrical outer shell 1 by a thread, making it detachable and easy to replace. The reverse osmosis membrane module 2 consists of an annular membrane 201 and a circular membrane 202. The water used for brewing the Trichosanthes kirilowii wine enters through the feed pipe at the top of the cylindrical outer shell 1 and then flows directly downwards into the space of the reverse osmosis membrane module 2. The reverse osmosis membrane module 2 removes most ions, solutes, microorganisms, and high molecular weight pigments, thereby significantly reducing ash content, conductivity, nitrates, pesticide residues, bacteria, etc. In addition, the cylindrical shape composed of annular membrane 201 and circular membrane 202 can provide a large membrane area within a limited space.

[0018] Following the above, after prolonged use, the reverse osmosis membrane module 2 will accumulate a significant amount of impurities and contaminants inside. Over time, these deposits will severely impact the membrane's filtration performance, affecting the lifespan of the reverse osmosis membrane module 2 and subsequent filtration efficiency. To address this issue, such as... Figures 1-3 As shown, a drive motor 3 is installed on the top of the cylindrical outer shell 1. A rotating shaft 301, passing through the center of the reverse osmosis membrane module 2, is installed at the output end of the drive motor 3. A cleaning brush 302 for cleaning the inner wall of the annular membrane 201 and the top surface of the circular membrane 202 is installed on the surface of the rotating shaft 301. The cleaning brush 302 includes a docking bracket 3021 mounted on the rotating shaft 301. A first cleaning brush strip 3022 is inserted into the docking bracket 3021. A second cleaning brush strip 3023 is integrally formed at the bottom of the first cleaning brush strip 3022. The height of the first cleaning brush strip 3022 is adapted to the height of the annular membrane 201. A memory 303 is connected at the junction of the annular membrane 201 and the circular membrane 202. By operating the drive motor 3, the rotating shaft 301 is driven to rotate at a set speed, which drives the cleaning brush 302 to rotate synchronously. This causes the first cleaning brush 3022 to rotate and brush along the inner wall of the annular membrane 201, and the adhering substances brushed off will fall onto the circular membrane 202. In addition, the rotation of the second cleaning brush 3023 can cause the adhering substances on the circular membrane 202 to roll, preventing them from clogging the membrane pores. Furthermore, as the second cleaning brush 3023 rotates, it can guide some impurities to roll into the storage 303, thereby achieving the transfer of impurities.

[0019] To improve the effect of guiding impurities from the top surface of the circular membrane 202 into the memory 303 when the cleaning brush 2 3023 rotates, such as Figure 2 and Figure 3 As shown, a guide groove 2021 is provided on the top surface of the circular membrane 202 from the center to the edge. One end of the guide groove 2021 is connected to the inlet end of the memory 303, and the depth of the guide groove 2021 gradually increases from the center to the edge of the circular membrane 202. As the cleaning brush 3023 rotates once, most of the impurities pushed by it will eventually fall into the guide groove 2021, and then naturally roll down along the inclined bottom wall of the guide groove 2021 into the memory 303, thereby improving the effect of impurity transfer.

[0020] Additionally, the top surface of the circular membrane 202 has multiple annular grooves 2022 that radiate outward from the center, and these annular grooves 2022 are connected to the guide groove 2021. The bottom shape of the cleaning brush strip 3023 is adapted to the top surface shape of the circular membrane 202. The annular grooves 2022 give the top surface of the circular membrane 202 an uneven surface, thereby increasing the overall surface area.

[0021] It is worth mentioning that by controlling the rotating shaft 301 to rotate the cleaning brush 302 through the drive motor 3, it can not only brush the deposits on the inner wall of the cylindrical reverse osmosis membrane module 2, but also guide the brushed and rolled deposits into the storage 303 through the top shape of the circular membrane body 202 and the cleaning brush 3023, thereby achieving the purpose of transferring the deposits on the reverse osmosis membrane module 2 and thus improving its service life.

[0022] like Figure 3 As shown, the storage device 303 includes a guide tube 3031 connected to the reverse osmosis membrane module 2. A collection cylinder 3032 is connected to the bottom of the guide tube 3031. A return pipe 3033 connects the bottom of the collection cylinder 3032 and the cylindrical outer shell 1, with the end of the return pipe 3033 connected to the cylindrical outer shell 1 located below the reverse osmosis membrane module 2. An interceptor membrane module 3034 is installed inside the collection cylinder 3032. Control valves 3035 are installed on both the guide tube 3031 and the return pipe 3033. Impurities rolling down from the guide groove 2021 enter the collection cylinder 3032 through the guide tube 3031, are intercepted by the interceptor membrane module 3034, and accumulate on the interceptor membrane module 3034. Liquid, however, passes normally through the interceptor membrane module 3034 and then flows back to the cylindrical outer shell 1 along the return pipe 3033. In addition, the collection cylinder 3032 is detachably connected to the guide tube 3031 and the return tube 3033. When it is necessary to clean the collection cylinder 3032, the channel between the guide tube 3031 and the return tube 3033 is disconnected by closing the upper and lower control valves 3035. Then, the collection cylinder 3032 can be disassembled and the interceptor membrane module 3034 can be replaced.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
