Description

Technical Field

[0001] The utility model belongs to the technical field of reverse osmosis membrane maintenance in water treatment, and particularly relates to a reverse osmosis membrane demounting device. Background Technique

[0002] The reverse osmosis device mainly removes more than 99% of anions, cations, organic matters, heat sources, bacteria, etc. in water. Reverse osmosis (RO) consists of an RO membrane module, a high-pressure pump, an RO cleaning device, etc.

[0003] Reverse osmosis is a membrane separation technology membrane element that relies on the function of a selectively permeable (semi-permeable) membrane and uses pressure as the driving force. It is made of a reverse osmosis membrane guide cloth, a central tube, etc. Multiple RO elements are installed in a stainless steel pressure-resistant shell to form an RO module. Reverse osmosis is the key to the desalination system. Mature process design, reasonable operation, control, and management directly determine the normal and stable water output of the system, and are related to the service life of the reverse osmosis membrane. The water output after reverse osmosis treatment removes most of the inorganic salts and almost all organic matters and microorganisms (bacteria, heat sources, etc.), thus ensuring the high quality of the product water of this system.

[0004] After the reverse osmosis has been operating for a period of time, the performance of the reverse osmosis membrane will gradually decline. For example, when the flow rate decays and the pressure difference rises to a certain extent and cannot be restored to its original state through conventional flushing, chemical cleaning needs to be considered. If it is in the case of off-line cleaning, the reverse osmosis membrane in the reverse osmosis membrane shell needs to be removed and replaced. During the removal process, a large amount of manpower and material resources are required, and the operating skills of the construction personnel are required to be high.

[0005] Therefore, it is necessary to develop and design a reverse osmosis membrane demounting device with a simple structure, reasonable design, simple operation, low cost, safe operation, reduced labor intensity, labor saving, and cost saving. Content of the Utility Model

[0015] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0016] Please refer to Figure 1 and Figure 2 , a reverse osmosis membrane removal device, including a bottom plate 1, which serves as the basic structure of the membrane removal device, provides a stable support platform, and ensures the stability and load-bearing capacity of the entire device during operation. One side of the bottom plate is fixedly provided with a membrane housing fixing vertical plate 2, which is vertically fixed on the bottom plate and is used to support and fix the reverse osmosis membrane housing, ensuring the stable position of the membrane housing during the membrane removal process without moving or tilting. The reverse osmosis membrane housing 7 is fixed on the fixing vertical plate through a membrane housing fixing component 3, firmly fixing the reverse osmosis membrane housing on the membrane housing fixing vertical plate, preventing the membrane housing from falling off or being damaged during the membrane removal process, and ensuring the smooth progress of the membrane removal operation. Above the bottom plate, there is a membrane pushing rod 4, which serves as the main execution component of the membrane removal operation, directly acts on the reverse osmosis membrane housing, and realizes the removal of the membrane through its movement, with a direct and effective membrane removal effect. The membrane pushing rod is connected to a membrane pushing rod transfer device 5, and the membrane pushing rod transfer device drives the membrane pushing rod to perform a linear motion along the central line direction of the reverse osmosis membrane housing. The membrane pushing rod provides power and control, ensuring that the membrane pushing rod can perform precise and stable movement along the central line direction of the reverse osmosis membrane housing, thereby realizing efficient and accurate membrane removal operation. At the same time, the device can also adjust the movement speed and force of the membrane pushing rod according to actual needs to adapt to different membrane removal requirements.

[0017] Preferably, the membrane housing fixing component 3 includes a fixing ring 3-1 with an open-loop structure, which is tightly sleeved on the small-diameter part of the reverse osmosis membrane housing, providing a firm support and fixing effect, ensuring that the membrane housing does not move or shake axially during the membrane removal process; a guiding ring 3-2 with an open-loop structure, which is sleeved on the large-diameter part at the end of the reverse osmosis membrane housing. In addition to providing additional support and fixing effects, it also plays a guiding role, ensuring that the membrane housing can move stably along a predetermined path during the membrane removal process; a locking screw 3-3 is inserted between the fixing ring and the guiding ring, and the locking screw is fixed on the fixing vertical plate 2. The locking screw tightly connects the fixing ring and the guiding ring together, thereby firmly fixing the entire reverse osmosis membrane housing on the membrane housing fixing vertical plate, preventing any movement or detachment during the membrane removal process.

[0018] Preferably, the ejector rod transfer device 5 includes a driving motor 5-1 that provides a power source to drive the ejector rod to move along a set path to achieve the film removal operation. Its stability and reliability ensure the smooth progress of the film removal process. The output end of the driving motor is equipped with a driving sprocket 5-2, which is connected to the output end of the driving motor to convert the rotational motion of the motor into linear motion and directly drive the ejector rod to perform the film removal operation. Its design ensures the accuracy and efficiency of the motion; there are pressing sprockets 5-3 on both sides of the driving sprocket. An ejector rod is provided between the driving sprocket and the pressing sprockets; it is located on both sides of the driving sprocket and jointly clamps the ejector rod with the driving sprocket to ensure the stability and accuracy of the ejector rod during movement. At the same time, it also provides a certain clamping force to prevent the ejector rod from shifting or shaking during movement. The pressing sprocket is rotatably installed on the flipping frame 5-4, and the flipping frame 5-4 is hingedly installed on the hinge seat 5-5. This installation method allows the flipping frame to rotate or flip within a certain range, thereby adjusting the position of the pressing sprocket to keep it in the same straight line as the driving sprocket and coincide with the midline of the reverse osmosis membrane housing; as the support structure of the pressing sprocket, it allows the pressing sprocket and the driving sprocket to move in the same straight line and coincide with the midline of the reverse osmosis membrane housing. This ensures the accuracy and stability of the ejector rod during movement. The flipping frame is installed on the bottom plate 1 through the locking member 6 to firmly install the flipping frame on the bottom plate to ensure that the positions of the flipping frame and the pressing sprocket do not change during the film removal process, thereby ensuring the accuracy and stability of the film removal operation; the above-mentioned driving sprocket and pressing sprocket are in the same straight line and coincide with the midline of the reverse osmosis membrane housing.

[0019] Preferably, the locking assembly includes a U-shaped locking block 6-1 provided on the flipping frame on the side away from the driving sprocket. The design of the U-shaped locking block is used to firmly lock the flipping frame on the bottom plate after the flipping frame is adjusted to the appropriate position to prevent it from moving or shaking during the film removal process. This ensures the stability and accuracy of the film removal operation. A locking screw 6-2 is hinged on the bottom plate corresponding to the U-shaped locking block. The locking screw is used in cooperation with the U-shaped locking block. By rotating the locking screw, it can be inserted into the U-shaped locking block to firmly lock the flipping frame on the bottom plate. This design provides a reliable locking force to ensure the stability of the flipping frame during the film removal process. A wing nut 6-3 is installed on the locking screw. The design of the wing nut facilitates the operator to use tools or manually rotate to lock or loosen the locking screw. This improves the operation convenience and efficiency of the film removal device.
