Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis membrane cleaning technology, and in particular to a feeding mechanism and its reverse osmosis membrane cleaning device. Background Technology

[0002] Reverse osmosis membranes are typically artificial semi-permeable membranes that achieve high-precision separation through pressure. Their core function is to intercept more than 99% of dissolved salts, organic matter, and microorganisms in water. Reverse osmosis membranes usually require cleaning, which necessitates the use of reverse osmosis cleaning equipment.

[0003] Existing reverse osmosis membrane cleaning devices typically include a cleaning tank and a feeding mechanism. The cleaning tank uses a cleaning pump and a cleaning agent to flush the reverse osmosis membrane, and the cleaning agent is added into the cleaning tank through the feeding mechanism.

[0004] The feeding mechanism typically includes a feeding box, a feeding pipe, and a valve body. The feeding box is installed on top of the cleaning tank, and the cleaning agent inside the feeding box is added to the cleaning tank through the feeding pipe to mix with the cleaning water. The valve body controls the feeding operation of the feeding pipe. However, the feeding box is usually fixed in a designated position in the cleaning tank, which means that the cleaning agent can only be added to one position inside the cleaning tank. This results in a fixed feeding position, affecting the mixing time of the cleaning agent and the cleaning water. Therefore, it is necessary for the feeding mechanism to move the feeding box to add the cleaning agent. Utility Model Content

[0039] 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.

[0040] This utility model provides, for example Figures 1-4 The above describes a feeding mechanism.

[0041] Implementation 1: Includes a feeding box 1, a feed pipe 2, a feed pipe 3, and an auxiliary mechanism 4. The feeding box 1 is used to hold the cleaning agent. The feed pipe 2 is used to add the cleaning agent into the feeding box 1. The feed pipe 3 is used to add the cleaning agent from its interior into the cleaning tank for the feeding operation. The feed pipe 3 is equipped with an electric valve to control the feeding. The top of the cleaning tank is equipped with an elongated groove to allow the feed pipe 3 to slide inside. The feed pipe 2 is fixedly inserted and connected to the top of the feeding box 1, and the feed pipe 3 is fixedly inserted and connected to the bottom of the feeding box 1. The auxiliary mechanism 4 is located outside the feeding box 1 and is used to move and adjust the feeding position of the feeding box 1.

[0042] Furthermore, the auxiliary mechanism 4 includes an auxiliary seat 41, a sliding plate 42, and a drive assembly. The auxiliary seat 41 is conveniently connected to the sliding plate 42 to support the horizontal sliding of the feeding box 1. The sliding plate 42 is conveniently used to support the feeding box 1 and guide the sliding of the feeding box 1. The auxiliary seat 41 is located on the side of the feeding box 1, and the sliding plate 42 is fixedly connected to the side of the feeding box 1. The sliding plate 42 is slidably inserted into the inner cavity of the auxiliary seat 41. The drive assembly is located on the top of the feeding box 1.

[0043] Furthermore, the auxiliary mechanism 4 also includes a connecting plate 44, a square plate 45, a fixing member, and a mounting bracket 412. The connecting plate 44 facilitates the connection of adjacent auxiliary seats 41, the square plate 45 facilitates the support of the fixing cylinder 46, and the mounting bracket 412 is L-shaped. The mounting bracket 412 facilitates the support of the auxiliary seats 41, so that the auxiliary seats 41 are installed on the top of the cleaning tank. The connecting plate 44 is fixedly connected between adjacent auxiliary seats 41, the square plate 45 is fixedly connected to the top of the connecting plate 44, the fixing member is located on the auxiliary seat 41, and the mounting bracket 412 is fixedly connected to the bottom of the auxiliary seat 41.

[0044] Specifically, the drive assembly includes a support base 43, a fixed cylinder 46, a movable block 47, and an adjusting screw 48. The support base 43 facilitates the sliding of the movable block 47 within it. The fixed cylinder 46 supports the servo motor 49 and also supports the rotation of the adjusting screw 48. The movable block 47 facilitates the horizontal movement of the feeding box 1, thereby changing the feeding position of the feeding box 1 and allowing the cleaning agent to be fed laterally inside, reducing the mixing time between the cleaning agent and the cleaning water. The adjusting screw 48... 8 facilitates the horizontal movement of the movable block 47, which in turn facilitates the horizontal movement of the feeding box 1. The support base 43 is located at the top of the feeding box 1. The fixed cylinder 46 is fixedly connected to the side of the square plate 45. The movable block 47 is fixedly connected to the top of the feeding box 1. The movable block 47 is slidably inserted into the inner cavity of the support base 43. The adjusting screw 48 is located inside the support base 43. The outer wall of the adjusting screw 48 is threadedly inserted into the movable block 47. The outer wall of the adjusting screw 48 is rotatably inserted into the sides of both the square plate 45 and the fixed cylinder 46.

[0045] More specifically, the drive assembly also includes a servo motor 49, which is electrically connected to an external power supply via an external switch. The servo motor 49 drives the adjusting screw 48 to rotate in both directions, so that the feeding box 1 can move back and forth horizontally. The servo motor 49 is fixedly connected inside the fixed cylinder 46, and the output end of the servo motor 49 is connected to the adjusting screw 48 for transmission.

[0046] The principle of reverse osmosis membrane cleaning is to specifically remove contaminants from the membrane surface through the synergistic effect of physical flushing and chemical treatment, thereby restoring its performance. The reverse osmosis membrane cleaning process involves using a cleaning pump to apply a prepared chemical agent (such as an acidic solution to dissolve inorganic salt scale and an alkaline solution to decompose organic matter and biofilm) heated to a suitable temperature (25-40℃) and then flushing the reverse osmosis membrane surface at a high flow rate in a segmented circulation manner. The contaminants are removed by the permeation, complexation, and oxidation reactions of the agent. At the same time, the reaction depth is enhanced by static soaking. Finally, the residual agent and stripped material are replaced by low-pressure pure water rinsing, ultimately restoring the membrane flux and desalination rate, and extending the membrane's service life. The reverse osmosis membrane cleaning device is consistent with existing technology, so it will not be described in detail here.

[0047] Another objective of this invention is to provide a reverse osmosis membrane cleaning device, which includes the aforementioned feeding mechanism.

[0048] Example 2: Based on Example 1, the fastener includes a first frame 410 and a second frame 411. Both the first frame 410 and the second frame 411 are L-shaped. The first frame 410 and the second frame 411 are conducive to supporting the support base 43, which can increase the stability of the support base 43. The first frame 410 is fixedly connected between the support base 43 and one of the auxiliary seats 41, and the second frame 411 is fixedly connected between the support base 43 and the other auxiliary seat 41.
