Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment equipment, and in particular relates to reverse osmosis water treatment equipment. Background Art

[0002] Reverse osmosis is a membrane separation technology that uses pressure as the driving force by virtue of the function of selective permeable (semi-permeable) membranes. When the pressure applied to the system is greater than the osmotic pressure of the influent solution, water molecules continuously penetrate the membrane, flow through the water production channel into the central tube, and then flow out at one end. Impurities in the water, such as ions, organic matter, bacteria, viruses, etc., are retained on the inlet side of the membrane and then flow out at the concentrated water outlet, thereby achieving the purpose of separation and purification.

[0003] Related technology (publication number CN220951337U) discloses a reverse osmosis water treatment equipment, which is equipped with a primary filtration structure. After water enters the water inlet pipe, the water will enter the filter element through the water diversion pipe. The particulate impurities in the water cannot pass through the filter holes of the filter element and are filtered in the filter element, thereby achieving primary filtration of the water. It can effectively prevent particulate impurities from entering the reverse osmosis tube and clogging the reverse osmosis membrane, while improving the filtration effect. The threaded seat is turned by the handle and removed, and then the filter element is pressed to disassemble the filter element. The filter element can then be replaced or cleaned to achieve the beneficial effect of convenient disassembly and cleaning of the filter element.

[0004] Existing reverse osmosis water treatment equipment usually has multiple membrane shells, and the upper and lower corresponding membrane shells are installed on the equipment frame through positioning pins. After the equipment has been used for a period of time, when the membrane shell and the reverse osmosis membrane inside the membrane shell are disassembled and maintained, it is necessary to remove the positioning pins corresponding to each membrane shell separately, and the membrane shells after maintenance still need to be positioned one by one. Such operation steps are cumbersome and prolong the maintenance period. Utility Model Content

DETAILED DESCRIPTION

[0028] The following is a combination of specific implementation cases and attached Figures 1 to 6 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0029] See Figures 1 to 6As shown, a reverse osmosis water treatment equipment includes a base 1, a frame 2 is fixedly installed on the base 1, the frame 2 provides a support position for the installation of subsequent components, and multiple groups of beams 3 are respectively provided on the left and right sides of the frame 2. In this embodiment, there are six groups of beams 3, and each three groups of beams 3 are respectively installed at the left and right ends of the frame 2. The beams 3 provide support for the installation of subsequent membrane shells. The outer wall of the beam 3 is vertically penetrated by a limit rod 4 and a screw 5. The limit rod 4 and the screw 5 pass through the outer wall of the beam 3 and will not affect the connection between the beam 3 and the frame 2. The limiting rod 4 is fixedly connected to the frame 2, and the screw rod 5 is rotatably connected to the frame 2 through a bearing. When the screw rod 5 rotates under the action of an external force, since the screw rod 5 passes through the beam 3, the rotating screw rod 5 will not affect the beam 3, thereby ensuring the normal rotation of the screw rod 5. A first moving block 6 is provided on the sliding sleeve of the limiting rod 4, and a second moving block 7 is provided on the threaded sleeve of the screw 5. A connecting arm 8 is fixedly connected between the first moving block 6 and the second moving block 7. When the screw 5 rotates, it can drive the second moving block 7 to move, and then drive the second moving block 7 to move through the connecting arm 8. The first moving block 6 moves synchronously along the limiting rod 4, and the first clamping block 9 is fixedly installed on the side wall of the first moving block 6, and the second clamping block 10 is fixedly installed on the side wall of the second moving block 7. Through the synchronous movement of the first moving block 6 and the second moving block 7, the clamping block 9 and the second clamping block 10 can be driven to move synchronously. A limiting hoop 11 is provided on each crossbeam 3, and a clamping groove 12 is respectively opened at the front and rear ends of each limiting hoop 11. The first clamping block 9 and the second clamping block 10 are respectively embedded in the corresponding inner cavity of the clamping groove 12. By moving the first clamping block 9 and the second The clamping block 10 is embedded in the corresponding inner cavity of the clamping slot 12, and can synchronously limit the two ends of the limiting hoop 11, thereby achieving the stability of the position of the limiting hoop 11. A membrane shell 13 is placed on the beam 3, and the limiting hoop 11 is sleeved on the end of the membrane shell 13 to position the membrane shell 13. By limiting the position of the limiting hoop 11, the positioning and locking of the membrane shell 13 at the beam 3 is achieved; specifically, the external threads arranged on the outer walls of the left and right screws 5 are in opposite directions, thereby ensuring that when the two screws 5 rotate in opposite directions, the second moving block 7 sleeved on the corresponding outer wall can be achieved.

[0030] Main references Figure 6 As shown, the positions of the first clamping block 9 and the second clamping block 10 correspond to the clamping slot 12 up and down, thereby ensuring that the first clamping block 9 and the second clamping block 10 moving downward can be accurately embedded in the inner cavity of the clamping slot 12, thereby realizing the positioning of the limiting hoop 11, and the shape of the clamping slot 12 is rectangular. Through the rectangular clamping slot 12, the first clamping block 9 and the second clamping block 10 can be embedded in the corresponding clamping slot 12, and the clamping slot 12 can limit the three side walls of the first clamping block 9 and the second clamping block 10, ensuring that the first clamping block 9 and the second clamping block 10 will not move in the clamping slot 12 after being limited, so as to ensure that the position of the limiting hoop 11 after positioning is sufficiently stable.

[0031] Main references Figures 4 to 6 As shown, the two screws 5 are rotated synchronously by the power unit; the power unit includes first bevel gears 14 respectively installed at the bottom ends of the two screws 5, and also includes a plurality of positioning seats 15 fixedly installed on the inner wall of the frame 2, and a rotating rod 16 is rotatably provided on the positioning seat 15 through a bearing. The positioning seat 15 can provide support for the rotation of the rotating rod 16, and the left and right ends of the rotating rod 16 are respectively installed with second bevel gears 17, and the two second bevel gears 17 are respectively meshed with the two first bevel gears 14. The rotating rotating rod 16 drives the two second bevel gears 17 to rotate in opposite directions, thereby prompting the two first bevel gears 14 to rotate in opposite directions, so as to realize the opposite rotation of the two screws 5. Since the external threads arranged on the outer walls of the left and right screws 5 are in opposite directions, the two screws rotating in opposite directions are rotated in opposite directions. Each screw 5 can drive the second moving block 7 on its respective outer wall to move upward or downward synchronously, ensuring the unidirectional movement of the two second moving blocks 7; the power unit also includes a fourth bevel gear 21 installed in the middle of the rotating rod 16, and a motor 18 is installed on the rear side wall of the frame body 2. The output end of the motor 18 is connected to a driving shaft 19, and a third bevel gear 20 is installed at the end of the driving shaft 19, and the third bevel gear 20 is meshed with the fourth bevel gear 21. By turning on the motor 18, the driving shaft 19 and the third bevel gear 20 are driven to rotate, so as to prompt the fourth bevel gear 21 to drive the rotating rod 16 and the two second bevel gears 17 to rotate synchronously, and the two second bevel gears 17 drive the two corresponding meshing connected first bevel gears 14 to rotate synchronously in opposite directions; for specific details, mainly refer to Figure 5 As shown, the two second bevel gears 17 are arranged in opposition to each other, thereby ensuring that the rotating rod 16 can drive the two second bevel gears 17 to rotate synchronously, thereby driving the two first bevel gears 14 to rotate in opposite directions.

[0032] Main references Figure 1 and Figure 2 As shown, the base 1 is provided with a filter component 22, a precision filter 23, a high-pressure pump 24, and a sterile water tank 25. The filter component 22, the precision filter 23, the high-pressure pump 24, the membrane shell 13 and the sterile water tank 25 are connected in sequence. The filter component 22, the precision filter 23, the high-pressure pump 24 and the sterile water tank 25 are respectively existing equipment. The raw water enters the filter component 22 through the booster pump for multi-stage filtration treatment. The filter component 22 is provided with a salt box commonly used in the market for storing sodium chloride solution, which provides the required sodium chloride solution to support the normal operation of the equipment. The water treated by the filter component 22 enters the right end of the membrane shell 13 through the precision filter 23 and the high-pressure pump 24, and under the action of the membrane shell 13, the clean water is output to the sterile water tank 25 through the left end of the membrane shell 13; in addition, the membrane shell 13 is an existing equipment, and its inner cavity is provided with a reverse osmosis membrane. The water is reverse osmosis filtered through the action of the reverse osmosis membrane, which will not be described in detail here.

[0033] It is worth noting that in this application, the motor 18 adopts a self-locking motor commonly used on the market whose output end can be locked. When the motor stops working, the output end can self-lock and will not rotate under external force. The motor 18 is a forward and reverse motor commonly used on the market, and its output end can rotate forward or reverse according to usage requirements. The above-mentioned existing components will not be described in detail here.

[0034] The working principle of a reverse osmosis water treatment device in this embodiment is as follows:

[0035] After the equipment has been used for a period of time, when all the membrane shells 13 are disassembled for maintenance, the motor 18 is turned on to drive the drive shaft 19 and the third bevel gear 20 to rotate, so as to prompt the fourth bevel gear 21 to drive the rotating rod 16 and the two second bevel gears 17 to rotate synchronously. The two second bevel gears 17 drive the two corresponding meshing connected first bevel gears 14 to rotate synchronously in opposite directions. Since the external threads on the two screw rods 5 are in opposite directions, the two first bevel gears 14 rotating in opposite directions respectively drive the two screw rods 5 to rotate, prompting the second movable rods 16 and the second movable rods 17 respectively threaded on the two screw rods 5 to rotate synchronously. The block 7 moves upward. Since the left and right groups of second moving blocks 7 are connected to the corresponding first moving blocks 6 through the connecting arms 8, the second moving block 7 that moves upward drives the corresponding first moving block 6 to move upward synchronously through the connecting arms 8. As the first moving block 6 and the second moving block 7 move upward, the first clamping block 9 and the second clamping block 10 are separated from the inner cavity of the clamping slot 12 at the corresponding positions. At this time, the limiting hoop 11 loses the limiting effect of the first clamping block 9 and the second clamping block 10, and the limiting hoop 11 can be disassembled, and the membrane shell 13 that has lost the limiting effect of the limiting hoop 11 can be disassembled and maintained.

[0036] When reinstalling the membrane shell 13 after maintenance, refer to the above steps, and rotate the output end of the motor 18 in the opposite direction to drive the two screws 5 to rotate in the opposite direction, thereby prompting the first moving block 6 and the second moving block 7 at the corresponding positions to move downward synchronously, prompting the first clamping block 9 and the second clamping block 10 to move downward synchronously to the inner cavity of the clamping slot 12 embedded in the corresponding position, so as to realize the positioning of the limiting hoop 11 at the beam 3, that is, the positioning and locking of the membrane shell 13 by the limiting hoop 11;

[0037] The filter assembly 22, the precision filter 23, the high-pressure pump 24 and the sterile water tank 25 are respectively existing equipment. The raw water enters the filter assembly 22 through the booster pump for multi-stage filtration treatment. The filter assembly 22 is provided with a salt tank commonly used in the market for storing sodium chloride solution to provide the required sodium chloride solution to support the normal operation of the equipment. The water treated by the filter assembly 22 enters the right end of the membrane shell 13 through the precision filter 23 and the high-pressure pump 24. Under the action of the membrane shell 13, the purified water is output through the left end of the membrane shell 13 to the sterile water tank 25;

[0038] Compared with the traditional method of individually positioning each membrane shell, the utility model is more convenient, and can simultaneously realize the synchronous positioning and locking of the limiting hoops 11 at the left and right ends of multiple membrane shells 13, saving positioning steps, shortening the time for disassembly and assembly of the limiting hoops 11, and thus shortening the overall maintenance time of the equipment. It is more practical, and can realize the synchronous positioning of the two ends of the membrane shell 13 at one time, and adopts one driving force to drive the two screws 5 to rotate synchronously, thereby increasing the synchronization of the equipment and saving more driving force.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
