Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis membrane housing technology, and in particular to a quick-release end cap for reverse osmosis membrane housing. Background Technology

[0002] The end caps of the reverse osmosis membrane housing are one of the most crucial components of a reverse osmosis system. They are primarily used to seal both ends of the reverse osmosis membrane, ensuring the membrane's sealing and stability during operation. The design and materials of the end caps directly affect the system's performance and lifespan; therefore, several factors must be considered when selecting and using them. First, the end caps are typically made of corrosion-resistant, high-pressure-resistant engineering plastics or composite materials to withstand the high-concentration brine and high-pressure environment of the reverse osmosis process. Second, the structural design of the end caps should match the specifications of the membrane housing to achieve a good sealing effect. Furthermore, the internal flow channel design of the end caps must be reasonable to improve the uniformity and kinetic stability of the water flow, thereby enhancing the overall separation performance. The end caps of the reverse osmosis membrane housing are not only a component of the physical structure but also play a vital role in maintaining the efficiency and safety of the reverse osmosis equipment.

[0003] In most cases, the end caps of existing reverse osmosis membrane housings are connected to the membrane housing by multiple baffles. Because these baffles are independently installed, disassembly and reassembly take a considerable amount of time. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-release end cap for reverse osmosis membrane housings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-release end cap for a reverse osmosis membrane housing includes an outlet component. An end cap is fitted onto the top of the outlet component. A receiving groove is formed on the surface of the end cap. Multiple baffles are slidably connected inside the receiving groove, and the baffles are evenly arranged in a ring. Two first sliding grooves are symmetrically formed inside the receiving groove on the side near the baffles. Each of the two first sliding grooves has a reset mechanism for resetting the baffles. A second sliding groove is formed on the top of the end cap on the side near the baffles. Squeezing plates are slidably connected inside the multiple second sliding grooves, and the multiple squeezing plates cooperate with the baffles. The top of the multiple squeezing plates is fixedly connected to the same pressure plate. The bottom of the multiple squeezing plates has an adjustment mechanism for adjusting the squeezing plates. A nut is provided on the surface of the outlet component near the pressure plate, and the nut cooperates with the outlet component. The bottom of the nut has a constraint mechanism for restraining the nut. The squeezing plates ensure that the baffles can move simultaneously.

[0007] As a further embodiment of this utility model, the reset mechanism includes a support column, which is fixedly connected inside the first slide groove, and a baffle is sleeved on the surface of the support column. A first spring is sleeved on the surface of the support column, with one end of the first spring fixedly connected to one side inside the first slide groove and the other end of the first spring fixedly connected to one side of the baffle. By setting the first spring, the baffle can be reset.

[0008] As a further embodiment of this utility model, the adjustment mechanism includes two limiting posts, both of which are slidably connected to the bottom of the extrusion plate and fixedly connected to the inner surface of the storage groove. A second spring is sleeved on the surface of each of the two limiting posts, the top ends of the two second springs are fixedly connected to the bottom of the extrusion plate, and the bottom ends of the two second springs are fixedly connected to the inner surface of the storage groove. The extrusion plate can be adjusted by the setting of the second springs.

[0009] As a further embodiment of this utility model, the constraint mechanism includes a T-shaped ring, which is fixedly connected to the top of the pressure plate and is arranged in a ring shape. A ratchet is sleeved on the surface of the T-shaped ring, and the surface of the ratchet is fixedly connected to the bottom of the nut. A pawl is fitted on the surface of the ratchet, and the pawl is rotatably connected to the top of the pressure plate. Two third springs are fixedly connected to the surface of the pawl away from the ratchet, and the other ends of the two third springs are fixedly connected to the top of the pressure plate. By setting up the ratchet, the nut can be constrained.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model adopts a technical solution of pressing the baffle with an extrusion plate, which ensures that the baffles can move simultaneously. This effectively solves the problem that multiple baffles are independently set, which leads to a lot of time required for disassembly. A pressure plate is installed at the bottom of the nut, and an extrusion plate is installed at the bottom of the pressure plate. Multiple baffles are installed inside the end cover, and the multiple baffles cooperate with the extrusion plate. A first spring is installed on the top of the baffle. When the extrusion plate stops pressing the baffle, the first spring will drive the baffle to reset, thereby releasing the constraint of the baffle on the end cover. After the constraint is released, the end cover can be removed. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1 - Figure 5 A quick-release end cap for a reverse osmosis membrane housing includes an outlet component 1, with an end cap 2 fitted onto the top of the outlet component 1. The end cap 2 has a receiving groove 201 on its surface, and multiple baffles 204 are slidably connected inside the receiving groove 201, arranged in a ring. Two first sliding grooves 202 are symmetrically formed inside the receiving groove 201 on the side near the baffles 204, each containing a reset mechanism for resetting the baffles 204. A second sliding groove 207 is formed on the top of the end cap 2 on the side near the baffles 204, and the second sliding grooves 207 are slidably connected inside the second sliding grooves. The device is dynamically connected to a squeezing plate 301, and multiple squeezing plates 301 cooperate with baffles 204. The top of multiple squeezing plates 301 is fixedly connected to the same pressure plate 3. Through the setting of the pressure plate 3, multiple baffles 204 can move simultaneously. The bottom of multiple squeezing plates 301 is provided with an adjustment mechanism for adjusting the squeezing plates 301. The surface of the water outlet 1 near the pressure plate 3 is provided with a nut 4, and the nut 4 cooperates with the water outlet 1. The bottom of the nut 4 is provided with a constraint mechanism for constraining the nut 4. Through the setting of the squeezing plates 301, it can be ensured that the baffles 204 can move simultaneously.

[0020] Preferably, the reset mechanism includes a support column 205, which is fixedly connected inside the first slide groove 202, and a baffle 204 is sleeved on the surface of the support column 205. A first spring 206 is sleeved on the surface of the support column 205. One end of the first spring 206 is fixedly connected to one side inside the first slide groove 202, and the other end of the first spring 206 is fixedly connected to one side of the baffle 204. By setting the first spring 206, the baffle 204 can be reset.

[0021] Preferably, the adjustment mechanism includes two limiting posts 302, both of which are slidably connected to the bottom of the extrusion plate 301 and fixedly connected to the inner surface of the storage groove 201. A second spring 303 is sleeved on the surface of each of the two limiting posts 302. The top ends of the two second springs 303 are fixedly connected to the bottom of the extrusion plate 301, and the bottom ends of the two second springs 303 are fixedly connected to the inner surface of the storage groove 201. The extrusion plate 301 can be adjusted by the setting of the second springs 303.

[0022] Preferably, the constraint mechanism includes a T-shaped ring 305, which is fixedly connected to the top of the pressure plate 3 and is arranged in a ring shape. A ratchet 401 is sleeved on the surface of the T-shaped ring 305, and the surface of the ratchet 401 is fixedly connected to the bottom of the nut 4. A pawl 402 is fitted on the surface of the ratchet 401 and is rotatably connected to the top of the pressure plate 3. Two third springs 403 are fixedly connected to the surface of the pawl 402 away from the ratchet 401. The pawl 402 can be constrained by the third springs 403. The other ends of the two third springs 403 are fixedly connected to the top of the pressure plate 3. The nut 4 can be constrained by the ratchet 401.

[0023] Working principle: When the end cap 2 needs to be disassembled, the pawl 402 is rotated first to release its constraint on the ratchet 401. A nut 4 is installed on the top of the ratchet 401, and the nut 4 cooperates with the water outlet component 1. Therefore, when the pawl 402 is no longer constraining the ratchet 401, the nut 4 can be rotated to release its connection with the water outlet component 1. A pressure plate 3 is installed at the bottom of the nut 4, and a squeezing plate 301 is installed at the bottom of the pressure plate 3. Therefore, when the nut 4 moves upward, the pressure plate 3 will drive the squeezing plate 301 to move upward synchronously. Multiple [other components] are installed inside the end cap 2. There are multiple baffles 204, and all of them cooperate with the extrusion plate 301. Because the side of the extrusion plate 301 near the baffle 204 is inclined, when the nut 4 is connected to the water outlet 1, the extrusion plate 301 will extrude the baffle 204, so that it can connect with the membrane shell. A first spring 206 is installed on the top of the baffle 204. When the extrusion plate 301 stops extruding the baffle 204, the first spring 206 will drive the baffle 204 to reset, thereby releasing the constraint of the baffle 204 on the end cap 2. After the constraint is released, the end cap 2 can be removed.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
