Description

Technical Field

[0001] This utility model is a reverse osmosis water treatment device, belonging to the field of water treatment. Background Technology

[0002] Reverse osmosis treatment of water is crucial in detergent manufacturing. Due to its highly efficient separation characteristics, reverse osmosis technology is widely used in many fields. Its principle is to separate the solute from the solvent in a solution by using a semi-permeable membrane that allows only water to pass through, under pressure higher than the osmotic pressure of the solution.

[0003] In existing technologies, some reverse osmosis water treatment equipment requires the solution to be added into the reverse osmosis filter tank before use. The solution is then treated by reverse osmosis through the pre-filter and the permeate membrane. During this process, the cylinder drives the pusher head to move inside the reverse osmosis filter tank, which increases the pressure inside the filter tank and thus accelerates the reverse osmosis efficiency. However, it is difficult to accurately control the pressure inside the reverse osmosis filter tank by relying solely on the cylinder to push the pusher head. Furthermore, when the pressure is too high, it can easily damage the permeate membrane or components inside the equipment, seriously affecting the service life and treatment effect of the equipment. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to address the problem that some reverse osmosis water treatment equipment cannot control the pressure in the reverse osmosis filter tank by simply pushing the pusher head with a cylinder, making it difficult to accurately adjust the pressure. Furthermore, when the pressure is too high, it is easy to damage the permeation membrane or the components inside the equipment, which seriously affects the service life and treatment effect of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reverse osmosis water treatment device, comprising a first cylinder, a scale fixedly connected to the outer side of the first cylinder, a second cylinder fixedly connected to the inner wall of the first cylinder, a cylinder at the top of the second cylinder, a pressure boosting seat fixedly connected to the telescopic end of the cylinder, a plurality of openings on the surface of the pressure boosting seat, a plurality of sliding grooves inside the pressure boosting seat, a stop block slidably connected in the sliding groove, a first return spring fixedly connected to one side of the stop block, a transmission block fixedly connected to one side of the stop block above the sliding groove, a contact block slidably connected to the bottom end of the pressure boosting seat, a second return spring sleeved on the surface of the contact block, a primary filter screen disposed inside the second cylinder outside the pressure boosting seat, and a permeation membrane disposed inside the second cylinder outside the primary filter screen.

[0006] Furthermore, the top of the booster seat is provided with an air jet pipe, a plurality of nozzles are fixedly connected to the outside of the air jet pipe, a connector is fixedly connected to the top of the air jet pipe, and the surface of the connector is fixedly connected with threads.

[0007] Furthermore, a fixing ring is fitted on the surface of the jet pipe on one side of the nozzle, and a fixing bolt passes through the fixing ring. The fixing bolt is threadedly connected to the booster seat.

[0008] Furthermore, a maintenance cover is provided at the top of the first cylinder, and the maintenance cover is fixedly connected to the cylinder. Several mounting bolts are inserted inside the maintenance cover, and the mounting bolts are threadedly connected to the first cylinder. A liquid outlet pipe is fixedly connected to the bottom of the first cylinder, and a first cap is threadedly connected to the surface of the liquid outlet pipe.

[0009] Furthermore, the inspection cover and the inner wall of the second cylinder are both fixedly connected with a first positioning ring, and the inspection cover and the inner wall of the second cylinder are both fixedly connected with a second positioning ring outside the first positioning ring.

[0010] Furthermore, a liquid inlet pipe is fixedly connected to one side of the second cylinder, and a slag outlet pipe is fixedly connected to the bottom end of the second cylinder. A second cap is threaded onto the surface of the slag outlet pipe, and the diameter of the slag outlet pipe is smaller than the diameter of the liquid outlet pipe.

[0011] Furthermore, the abutment is arc-shaped, and an anti-slip pad is fixedly connected to the side of the abutment near the opening.

[0012] The beneficial effects of this utility model are as follows: During the process of treating the solution, the cylinder can be activated to drive the pressure booster seat to move down in the second cylinder, thereby increasing the pressure in the second cylinder and thus speeding up the processing efficiency. The scale makes it easy to control the pressure in the second cylinder. When the pressure in the second cylinder is too high, the contact block, the second return spring, the slide, the transmission block and the first return spring will drive the stop block to extend out of the opening and press against the inner wall of the primary filter screen to prevent the pressure booster seat from moving down further, thereby avoiding damage to the equipment due to excessive pressure in the second cylinder.

[0013] As the booster moves, it also moves the jet pipe, which, together with the connector and nozzle, can clean the primary filter, thus preventing the primary filter from being clogged by larger impurities.

[0014] Rotating the mounting bolts to detach it from the first cylinder and then pulling the inspection cover away from the first cylinder allows for the disassembly of the primary filter or permeation membrane, thus ensuring the equipment's treatment effect. The first and second positioning rings, in conjunction with these rings, can limit the position of the primary filter and permeation membrane within the second cylinder. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1 to 6This utility model provides a technical solution: a reverse osmosis water treatment device, including a first cylinder 1, a scale 101 fixedly connected to the outside of the first cylinder 1, a second cylinder 2 fixedly connected to the inner wall of the first cylinder 1, a cylinder 3 provided at the top of the second cylinder 2, a pressure boosting seat 4 fixedly connected to the telescopic end of the cylinder 3, a plurality of openings 401 on the surface of the pressure boosting seat 4, a plurality of sliding grooves 402 provided inside the pressure boosting seat 4, a stop block 403 slidably connected inside the sliding groove 402, a first return spring 404 fixedly connected to one side of the stop block 403, a transmission block 405 fixedly connected to one side of the stop block 403 above the sliding groove 402, a contact block 406 slidably connected to the bottom of the pressure boosting seat 4, a second return spring 407 sleeved on the surface of the contact block 406, a primary filter screen 5 provided inside the second cylinder 2 outside the pressure boosting seat 4, and a permeation membrane 6 provided inside the second cylinder 2 outside the primary filter screen 5.

[0025] During the solution processing, the cylinder 3 can be activated to move the pressure booster 4 downwards within the second cylinder 2, thereby increasing the pressure in the second cylinder 2 and accelerating the processing efficiency. The scale 101 facilitates the control of the pressure in the second cylinder 2. When the pressure in the second cylinder 2 is too high, the contact block 406, the second return spring 407, the slide 402, the transmission block 405, and the first return spring 404 will drive the stop block 403 to extend out of the opening 401 and press against the inner wall of the primary filter screen 5 to prevent the pressure booster 4 from moving further downwards, thus avoiding damage to the equipment due to excessive pressure in the second cylinder 2.

[0026] Preferably, the abutment 403 is arc-shaped, and an anti-slip pad 408 is fixedly connected to the side of the abutment 403 near the opening 401.

[0027] The arc shape of the abutment 403 allows it to fit more closely to the inner wall of the primary filter 5. In conjunction with the anti-slip pad 408, it can not only increase the friction between the abutment 403 and the primary filter 5 to improve the limiting effect on the booster seat 4, but also prevent the abutment 403 from damaging the primary filter 5.

[0028] Please see Figure 5 and Figure 6 The present invention provides a technical solution: a jet pipe 7 is provided at the top of the pressurizing seat 4, a plurality of nozzles 701 are fixedly connected to the outside of the jet pipe 7, a connector 702 is fixedly connected to the top of the jet pipe 7, and a thread is fixedly connected to the surface of the connector 702.

[0029] As the booster seat 4 moves, it will also drive the jet pipe 7 to move. Together with the connector 702 and the nozzle 701, it can clean the primary filter screen 5, thereby preventing the primary filter screen 5 from being blocked by larger impurities.

[0030] Preferably, a fixing ring 703 is fitted on the surface of the jet pipe 7 on one side of the nozzle 701, and a fixing bolt 704 is inserted inside the fixing ring 703. The fixing bolt 704 and the booster seat 4 are connected by threads.

[0031] Rotate the fixing bolt 704 to disengage it from the booster seat 4, and then pull the fixing ring 703 to move it away from the jet pipe 7 to disassemble the jet pipe 7, thereby facilitating the maintenance of the jet pipe 7.

[0032] Please see Figures 1 to 4 The present invention provides a technical solution: a maintenance cover 102 is provided at the top of the first cylinder 1, the maintenance cover 102 is fixedly connected to the cylinder 3, a plurality of mounting bolts 103 are provided inside the maintenance cover 102, the mounting bolts 103 are threadedly connected to the first cylinder 1, a liquid outlet pipe 104 is fixedly connected to the bottom of the first cylinder 1, a first cap 105 is threadedly connected to the surface of the liquid outlet pipe 104, a liquid inlet pipe 201 is fixedly connected to one side of the second cylinder 2, a slag outlet pipe 202 is fixedly connected to the bottom of the second cylinder 2, a second cap 203 is threadedly connected to the surface of the slag outlet pipe 202, and the diameter of the slag outlet pipe 202 is smaller than the diameter of the liquid outlet pipe 104.

[0033] Rotating the mounting bolt 103 to detach it from the first cylinder 1, and then pulling the inspection cover 102 away from the first cylinder 1, allows for the disassembly of the primary filter 5 or the permeation membrane 6, thus ensuring the treatment effect of the equipment.

[0034] Preferably, the inspection cover 102 and the inner wall of the second cylinder 2 are both fixedly connected with a first positioning ring 8, and the inspection cover 102 and the inner wall of the second cylinder 2 are both fixedly connected with a second positioning ring 9 outside the first positioning ring 8.

[0035] The positions of the primary filter 5 and the permeation membrane 6 in the second cylinder 2 can be defined by the first positioning ring 8 and the second positioning ring 9.

[0036] Specific implementation method: The solution to be treated is added into the second cylinder 2 through the inlet pipe 201. The primary filter screen 5 can intercept larger impurities in the water. With the help of the permeation membrane 6, the solution can be further filtered. Finally, the first cap 105 is rotated to detach it from the outlet pipe 104, so that the treated solution flows out from the outlet pipe 104. The second cap 203 is rotated to detach it from the sludge outlet pipe 202, so that the concentrated solution or filter residue flows out from the sludge outlet pipe 202. The outside of the sludge outlet pipe 202 is connected to several inclined branch pipes to ensure that the concentrated solution or filter residue located at the primary filter screen 5 and the permeation membrane 6 can enter the sludge outlet pipe 202 along the branch pipes.

[0037] During the solution processing, cylinder 3 can be activated. Cylinder 3 will drive the pressure booster 4 to move down inside the second cylinder 2, thereby increasing the pressure in the second cylinder 2 and accelerating the processing efficiency. By using the scale 101 fixed on one side of the first cylinder 1 to observe the movement distance of the pressure booster 4, it is easy to control the pressure in the second cylinder 2. During this process, the contact block 406 will move inside the pressure booster 4 due to the pressure in the second cylinder 2 and squeeze the second return spring 407. Then, through the transmission block 405, the abutment block 403 will slide along the slide groove 402 opened on the inner wall of the pressure booster 4 and squeeze the first return spring 404. When the pressure in the second cylinder 2 is too high, the abutment block 403 will extend out of the opening 401 opened on the surface of the pressure booster 4 and press against the inner wall of the primary filter screen 5 to prevent the pressure booster 4 from moving down further, thereby avoiding damage to the equipment due to excessive pressure in the second cylinder 2.

[0038] As the booster seat 4 moves, it will also move the jet pipe 7 installed on its top. The jet pipe 7 is connected to an external air pump through the connector 702 fixed on its top. The air pump will spray into the jet pipe 7 and be sprayed onto the primary filter 5 through the nozzle 701, which can clean the primary filter 5 and thus prevent the primary filter 5 from being blocked by large impurities.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
