Description

Technical Field

[0001] This invention belongs to the field of water treatment membrane technology, and specifically relates to a water treatment membrane assembly that is easy to replace. Background Technology

[0002] Water treatment membranes generally refer to water treatment filtration membranes, which have selective osmosis separation functions. They are usually installed in pipes to filter wastewater through dialysis, osmosis, or reverse osmosis. They are also removable and replaceable. For reverse osmosis membranes, they are installed in pipes as reverse osmosis membrane cartridges for water treatment. When installing reverse osmosis membrane cartridges, the end of the cartridge that is initially inside the pipe will contact the inner wall of the pipe, generating friction. Furthermore, when removing the reverse osmosis membrane cartridge, workers need to use pliers to forcefully remove the old reverse osmosis membrane cartridge from the pipe, which requires a certain level of strength and makes it inconvenient to replace the old reverse osmosis membrane cartridge with the new one. Summary of the Invention

[0003] The purpose of this invention is to provide a water treatment membrane assembly that is easy to replace, in order to solve the problems mentioned in the background art.

[0006] Preferably, the gas evacuation module includes a fan, a positioning plate, a connecting pipe, and a hollow ring. The hollow ring is fitted onto the right side of the outer wall of the outer pipe, and the fan is located on the left side of the hollow ring. The positioning plate is symmetrically connected to both sides of the fan, and the positioning plate is fixedly connected to the outer pipe by positioning bolts. The connecting pipe is connected between the fan and the hollow ring, and the connecting pipe is connected to the inner cavity of the hollow ring. When the fan is turned on, the air in the cavity on the left side of the sealing plate is filled and extracted.

[0007] Preferably, the gas evacuation module further includes a translation rod, a receiving sleeve, and a connecting branch pipe. The translation rod, receiving sleeve, and connecting branch pipe are all circumferentially arrayed and connected to the outside of the reverse osmosis membrane cylinder. A gap is left between the translation rod, receiving sleeve, and connecting branch pipe and the reverse osmosis membrane cylinder. The receiving sleeve is fitted onto the outer wall of the right end of the translation rod. The connecting branch pipe is connected to the inner wall of the hollow ring. The end of the connecting branch pipe away from the hollow ring passes through the outer pipe and is connected to the receiving sleeve, so that air enters the primary circular hole through the connecting branch pipe, receiving sleeve, and translation rod.

[0008] The translational members are designed as hollow structures.

[0009] The right end of the storage sleeve is a sealed structure.

[0010] Preferably, the sealed outer top module includes a positioning ring, a primary circular hole, an annular connecting chamber, an air guide block, an air guide chamber, and a secondary circular hole. The positioning ring is sleeved on the left end of the outer wall of the reverse osmosis membrane cylinder. The primary circular holes are arranged in a circumferential array on the right side of the positioning ring. The annular connecting chamber is opened inside the positioning ring and is connected to the primary circular hole. The air guide block is arranged in a circumferential array on the outer wall of the positioning ring. The air guide chamber is opened inside the air guide block. The secondary circular holes are arranged in a circumferential array on the outer wall of the positioning ring and on the middle part of the side of the air guide block near the positioning ring. The air guide chamber is connected to the annular connecting chamber through the secondary circular hole to ensure smooth airflow, thereby ensuring the evacuation and filling of air on the left side of the sealing plate.

[0011] A gap is left between the air guide block and the inner wall of the outer tube to prevent the air guide block from contacting the outer tube and affecting the movement of the positioning ring;

[0012] Rollers are symmetrically connected to both sides of the air guide block, and the rollers fit against the inner wall of the outer tube, which facilitates the sliding of the positioning ring inside the outer tube;

[0013] The right end of the outer wall of the positioning ring is designed as a ring-shaped curved surface structure;

[0014] The inner wall of the positioning ring is provided with a primary equipment slot, and a primary contact switch is embedded in the primary equipment slot. The new reverse osmosis membrane tube is attached to the primary contact switch. The primary contact switch transmits data to the external terminal. The external terminal controls the fan to turn on and extracts the air between the left side of the sealing plate and the outer pipe through the gas evacuation module.

[0015] The left end of the translation rod is connected to the positioning ring, and the hollow structure of the translation rod is connected to the annular connecting chamber;

[0016] A limiting plate is connected to the left circumferential array on the inner wall of the positioning ring. The limiting plate fits into the reverse osmosis membrane cartridge, restricting the reverse osmosis membrane cartridge and preventing the left end of the reverse osmosis membrane cartridge from protruding from the positioning ring, thereby ensuring the installation effect of the reverse osmosis membrane cartridge.

[0017] Preferably, the sealing outer top module also includes a circular hole, a transverse sleeve, a sealing plate and a through circular hole. The circular hole and the transverse sleeve are both located in the middle of the left side of the gas guide block. The circular hole is opened on the gas guide block, and the interior of the transverse sleeve is connected to the gas guide chamber through the circular hole. The sealing plate is connected to the left end of the transverse sleeve. The through circular holes are arranged in a circumferential array inside the sealing plate and are connected to the interior of the transverse sleeve, so that gas can enter the left side of the sealing plate.

[0018] The outer wall of the sealing plate fits snugly against the inner wall of the outer tube, and the sealing plate slides between the sealing plate and the outer tube to ensure the sealing between the left side of the sealing plate and the outer tube.

[0019] Preferably, the sealed outer top module also includes a transfer pipe, a three-stage solenoid valve, a first-stage connecting ring and a second-stage connecting ring. The transfer pipe is connected to the middle of the sealing plate, and the left end of the transfer pipe passes through the sealing plate. The three-stage solenoid valve is located on the transfer pipe. The first-stage connecting ring is sleeved on the outer wall of the left end of the transfer pipe. The second-stage connecting ring is connected to the middle of the right side of the sealing plate to ensure that the clean water in the outlet pipe can be discharged.

[0020] The right end of the water purification pipe passes through the outer pipe and is located inside the primary connecting ring to ensure the connection between the transfer fitting and the water purification pipe.

[0021] The sealing plate has a circular array of gap rods on its left side, which creates a gap between the left side of the sealing plate and the outer tube to ensure the introduction of gas.

[0022] The left end of the water outlet pipe is located inside the secondary connecting ring, and the water outlet pipe is connected to the transfer fitting and the clean water pipe respectively, so that the clean water discharged from the water outlet pipe can pass through the transfer fitting and the clean water pipe in sequence.

[0023] Preferably, the plugging module includes a plugging end cap, an inlet pipe, and a rubber ring gasket. The plugging end cap is located at the right end of the outer pipe, the inlet pipe is connected to the middle of the right end of the plugging end cap, and the rubber ring gasket is located on the left side of the plugging end cap. The rubber ring gasket is located in the inner cavity of the outer pipe, the outer wall of the rubber ring gasket is in contact with the inner wall of the outer pipe, and the left side of the rubber ring gasket is in contact with the reverse osmosis membrane cartridge, ensuring the sealing of the right end of the reverse osmosis membrane cartridge and the right end of the outer pipe, and allowing the sewage entering the outer pipe from the inlet pipe to enter the reverse osmosis membrane.

[0024] A secondary equipment slot is located on the upper left side of the plugging end cap. A secondary contact switch is embedded in the secondary equipment slot. The rubber ring gasket in the plugging module and the plugging end cap are separated from the outer tube. The secondary contact switch is also separated from the outer tube. The secondary contact switch transmits data to the external terminal. The external terminal controls the fan to start and simultaneously controls the primary, secondary, and tertiary solenoid valves to close. After installing the new reverse osmosis membrane cartridge, the rubber ring gasket and the plugging end cap are connected to the right end of the outer tube until the secondary contact switch contacts the outer tube. The secondary contact switch transmits data to the external terminal. The external terminal receives the data and controls the primary, secondary, and tertiary solenoid valves to open, enabling the new reverse osmosis membrane cartridge to treat the water.

[0025] Preferably, the plugging module further includes an auxiliary block and a ball head. The auxiliary block and the ball head are arranged in a circumferential array on the outer wall of the reverse osmosis membrane cylinder. The auxiliary block is connected to the inner wall of the outer tube. The ball head is located in the middle of the side of the auxiliary block near the reverse osmosis membrane cylinder and fits against the reverse osmosis membrane cylinder. The ball head supports the right end of the reverse osmosis membrane cylinder without affecting its movement.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: When the reverse osmosis membrane cartridge inside the outer tube needs to be replaced, the rubber ring gasket and the sealing end cap in the sealing module are separated from the outer tube, the secondary contact switch is separated from the outer tube, the secondary contact switch transmits data to the external terminal, the external terminal controls the fan to start, thereby guiding air into the chamber on the left side of the sealing plate through the gas guiding module, the gas pushes out the sealing plate and the old reverse osmosis membrane cartridge, the old reverse osmosis membrane cartridge is removed, the reverse osmosis membrane cartridge is separated from the primary contact switch, and when the new reverse osmosis membrane cartridge is installed in the outer tube, the left end of the new reverse osmosis membrane cartridge... The new reverse osmosis membrane cartridge is positioned within the positioning ring, and the outlet pipe is engaged within the secondary connecting ring. This raises the left end of the new reverse osmosis membrane cartridge, preventing friction between the left end of the new reverse osmosis membrane cartridge and the outer pipe. At this point, the new reverse osmosis membrane cartridge is in contact with the primary contact switch, which transmits data to the external terminal. The external terminal controls the fan to turn on, and through the gas evacuation module, the air between the left side of the sealing plate and the outer pipe is extracted, causing the sealing plate to move to the left. With just a slight push, the new reverse osmosis membrane cartridge, along with the sealing plate and positioning ring, can be inserted into the outer pipe, facilitating the installation of the new reverse osmosis membrane cartridge and improving the convenience of replacing it.

The annular connecting chamber 43, the secondary circular hole 46, the circular hole 411, the transverse sleeve 412, and the through circular hole 414 enter the chamber on the left side of the sealing plate 413. Gas pushes out the sealing plate 413, the positioning ring 41, and the old reverse osmosis membrane cartridge 2. The old reverse osmosis membrane cartridge 2 is removed, and the reverse osmosis membrane cartridge 2 is separated from the primary contact switch 49. When the new reverse osmosis membrane cartridge 2 is installed in the outer tube 1, the left end of the new reverse osmosis membrane cartridge 2 is in the positioning ring 41, and the outlet pipe 22 is engaged in the secondary connecting ring 418, thereby supporting the left end of the new reverse osmosis membrane cartridge 2. To prevent friction from occurring when the left end of the new reverse osmosis membrane cartridge 2 contacts the outer tube 1, the new reverse osmosis membrane cartridge 2 is in contact with the primary contact switch 49. The primary contact switch 49 transmits data to the external terminal, which controls the fan 31 to start. Through the gas evacuation module 3, the air between the left side of the sealing plate 413 and the outer tube 1 is extracted, causing the sealing plate 413 to move to the left. With a slight push, the new reverse osmosis membrane cartridge 2, along with the sealing plate 413 and the positioning ring 41, is inserted into the outer tube 1, facilitating the installation of the new reverse osmosis membrane cartridge 2. The high-efficiency reverse osmosis membrane cartridge 2 is convenient to replace. After the new reverse osmosis membrane cartridge 2 is installed, the rubber ring gasket 53 and the sealing end cap 51 are connected to the right end of the outer tube 1 until the secondary contact switch 55 contacts the outer tube 1. The secondary contact switch 55 transmits data to the external terminal. The external terminal receives the data and controls the opening of the primary solenoid valve 7, the secondary solenoid valve 9 and the tertiary solenoid valve 416, so that the new reverse osmosis membrane cartridge 2 can treat water. At this time, the wastewater pipe 6 is between the sealing plate 413 and the positioning ring 41, so that the wastewater discharged from the new reverse osmosis membrane cartridge 2 can be discharged.
