Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis membrane end plate disassembly technology, and in particular to a reverse osmosis membrane end plate remover. Background Technology

[0002] Because scale and other fouling substances often exist in membrane-based water treatment systems, the end plates of the reverse osmosis membrane system cannot be effectively removed on-site. Moreover, the end plates are often difficult to remove smoothly due to limited working space, scale, and aging of the rubber rings. Removal is time-consuming and laborious, and forceful removal can damage the end plates. Therefore, an end plate removal tool is needed to disassemble the end plates.

[0003] The existing reverse osmosis membrane endplate remover mainly includes an external threaded nut, a threaded rod, a baffle, a threaded seat, and a handle. The baffle slides on the threaded rod, the threaded seat is threadedly connected to the threaded rod, the external threaded nut is fixed on the threaded rod, and the endplate is fixed to the reverse osmosis membrane housing by several bolts. When the endplate needs to be removed, the threaded rod and the external threaded nut are manually rotated, so that the external threaded nut is threadedly connected to the endplate plug thread. The baffle is located between the reverse osmosis membrane housing and the handle. The handle drives the threaded seat to rotate, so that the threaded seat contacts the baffle. At this time, the threaded seat cannot move forward, so the threaded seat applies a rotational force to the threaded rod and the external threaded nut. Since the external threaded nut is limited by the endplate and cannot rotate, the external threaded nut converts the rotational force into a pulling force on the endplate, thereby pulling the endplate out of the reverse osmosis membrane housing.

[0004] However, in implementing the relevant technology, the existing reverse osmosis membrane endplate remover has the following problems: The existing device directly rotates the threaded rod and the threaded seat, so that the threaded seat is connected to the threaded endplate plug. This requires a large force to overcome the friction and resistance between the threads, making the device relatively labor-intensive to use. In addition, the handle length of the existing device is not convenient to adjust. When the handle is short, more force is required to obtain the same torque, which increases the labor intensity of the user. When the handle is long, the handle is inconvenient to use in a confined space, thus reducing the ease of use of the device. In view of this, a reverse osmosis membrane endplate remover is provided to overcome the above defects. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a reverse osmosis membrane endplate remover.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a reverse osmosis membrane endplate remover, comprising a reverse osmosis membrane housing, an endplate body fixed inside the reverse osmosis membrane housing by several bolts, a plug thread opening inside the endplate body, an external threaded nut threaded inside the plug thread opening, a threaded rod fixed on one side of the external threaded nut, a baffle on the side of the threaded rod, a threaded seat threadedly connected to the side of the threaded rod, a connector inside the threaded seat, an adjusting rod fixed on one side of the connector, a connecting groove inside the adjusting rod, a connecting rod inside the connecting groove, a handle fixed on one end of the connecting rod, an anti-slip pad on the side of the handle, a fixing bolt inside the adjusting rod, a mounting base fixed on one end of the threaded rod, a mounting head inside the mounting base, a fixing plate fixed on one side of the mounting head, two rotating rods fixed on the side of the fixing plate, and soft pads on the sides of both rotating rods.

[0007] As a further description of the above technical solution: the baffle has a movable hole inside, and the inside of the movable hole fits against the side of the threaded rod, so that the baffle can prevent the threaded seat from moving excessively.

[0008] As a further description of the above technical solution: the threaded seat has a connecting hole inside, and the inside of the connecting hole is threadedly connected to the side of the connector, so that the threaded seat can easily apply rotational force to the threaded rod.

[0009] As a further description of the above technical solution: the mounting base has a mounting hole inside, and the inside of the mounting hole is threadedly connected to the side of the mounting head, so that the mounting base can be easily connected to the mounting head.

[0010] As a further description of the above technical solution: the anti-slip pad has a positioning groove inside, and the inside of the positioning groove is fixedly connected to the side of the handle, so that the handle can easily drive the threaded seat to rotate.

[0011] As a further description of the above technical solution: both of the soft pads have a fixing groove inside, and the inside of the two fixing grooves is fixedly connected to the side of the two rotating rods respectively. The soft pads can improve the anti-slip ability of the rotating rods and prevent the rotating rods from injuring the user's hands.

[0012] As a further description of the above technical solution: the side of the fixing bolt is connected to the internal thread of the adjusting rod, and the connecting rod has several limiting holes inside. The side of the fixing bolt fits into the inside of the corresponding limiting hole, and the fixing bolt facilitates fixing the adjusting rod and the connecting rod together.

[0013] This utility model has the following beneficial effects:

[0014] This utility model designs a reverse osmosis membrane endplate removal device. Through a design that coordinates, rotating one end of two rotating rods simultaneously drives the threaded rod and the external threaded nut to rotate, causing the external threaded nut to connect with the threaded endplate plug of the endplate body. Because the rotating rod is relatively long, the lever arm for rotating the threaded rod is longer, making it more labor-saving than directly rotating the threaded rod. After the external threaded nut is connected to the endplate body, rotating the fixing bolt disengages it from the connecting rod. Moving the connecting rod to the right increases the total length between the adjusting rod, connecting rod, and handle. Moving the connecting rod to the left shortens the total length between the adjusting rod, connecting rod, and handle. Reversing the fixing bolt allows it to enter the corresponding limiting hole inside the connecting rod, thereby... The total length between the adjusting rod, connecting rod, and handle is fixed. Rotating the handle causes the threaded seat to rotate, bringing it into contact with the baffle. The threaded seat cannot move forward, thus applying a rotational force to the threaded rod and the external threaded nut. Since the external threaded nut is limited by the end plate body and cannot rotate, it converts the rotational force into a pulling force on the end plate body, pulling the end plate body out of the reverse osmosis membrane housing. This reduces the manual effort required to rotate the external threaded nut. Furthermore, the total length between the connecting rod, adjusting rod, and handle can be adjusted to increase the lever arm when rotating the threaded seat without affecting the normal rotation of the handle, making it easier to rotate the handle and improving the ease of use of the device.

[0021] Reference Figures 1-4The reverse osmosis membrane endplate removal device provided by this utility model includes a reverse osmosis membrane housing 1. An endplate body 2 is fixed inside the reverse osmosis membrane housing 1 by several bolts. A plug thread is opened inside the endplate body 2, and an external threaded nut 3 is threaded into the plug thread. A threaded rod 4 is fixed to one side of the external threaded nut 3, facilitating the rotation of the external threaded nut 3. A baffle 5 is provided on the side of the threaded rod 4, and a threaded seat 6 is threaded into the side of the threaded rod 4. A connector 7 is provided inside the threaded seat 6, and an adjusting rod 8 is fixed to one side of the connector 7. The adjusting rod 8 facilitates the limiting of the connecting rod 9. The adjusting rod 8 has an internal opening... A connecting groove is provided, and a connecting rod 9 is provided inside the connecting groove. A handle 10 is fixedly provided at one end of the connecting rod 9. An anti-slip pad 11 is provided on the side of the handle 10. The anti-slip pad 11 improves the anti-slip ability of the handle 10 and prevents the handle 10 from injuring the user's hand. A fixing bolt 12 is provided inside the adjusting rod 8. A mounting seat 13 is fixedly provided at one end of the threaded rod 4. A mounting head 14 is provided inside the mounting seat 13. A fixing plate 15 is fixedly provided on one side of the mounting head 14. The fixing plate 15 facilitates the fixing of the rotating rod 16. Two rotating rods 16 are fixedly provided on the side of the fixing plate 15. Both rotating rods 16 are provided with soft pads 17 on their sides.

[0022] As a further implementation of the above technical solution: the baffle 5 has a movable hole inside, and the inside of the movable hole fits against the side of the threaded rod 4, so that the baffle 5 can prevent the threaded seat 6 from moving excessively.

[0023] As a further implementation of the above technical solution: the threaded seat 6 has a connecting hole inside, and the inside of the connecting hole is threadedly connected to the side of the connector 7, so that the threaded seat 6 can easily apply rotational force to the threaded rod 4.

[0024] As a further implementation of the above technical solution: the mounting base 13 has a mounting hole inside, and the inside of the mounting hole is threadedly connected to the side of the mounting head 14, so that the mounting base 13 can be easily connected to the mounting head 14.

[0025] As a further implementation of the above technical solution: the anti-slip pad 11 has a positioning groove inside, and the inside of the positioning groove is fixedly connected to the side of the handle 10, so that the handle 10 can easily drive the threaded seat 6 to rotate.

[0026] As a further implementation of the above technical solution: both soft pads 17 have fixing grooves inside, and the inside of the two fixing grooves are fixedly connected to the sides of the two rotating rods 16 respectively. The soft pads 17 can improve the anti-slip ability of the rotating rods 16 and prevent the rotating rods 16 from pressing on the user's hands.

[0027] As a further implementation of the above technical solution: the side of the fixing bolt 12 is connected to the internal thread of the adjusting rod 8, and the connecting rod 9 has several limiting holes. The side of the fixing bolt 12 fits into the corresponding limiting hole, so that the fixing bolt 12 can fix the adjusting rod 8 and the connecting rod 9 together.

[0028] Working principle:

[0029] When using this invention, if it is necessary to remove the end plate body 2 from the reverse osmosis membrane housing 1, remove several bolts on the end plate body 2 and thread the mounting head 14 and mounting base 13 together. At this time, simultaneously rotate one end of the two rotating rods 16, thereby driving the threaded rod 4 to rotate, which in turn drives the external threaded nut 3 to rotate, so that the external threaded nut 3 is threadedly connected to the plug thread of the end plate body 2. Because the rotating rod 16 is relatively long, the lever arm when rotating the threaded rod 4 is relatively long, which is more labor-saving than directly rotating the threaded rod 4, thereby reducing the consumption of the device during use. With manual force, after the external threaded nut 3 is connected to the end plate body 2, the fixing bolt 12 is rotated, causing the fixing bolt 12 to move upward, thereby disengaging the fixing bolt 12 from the connecting rod 9. At this time, the connecting rod 9 loses its limit and moves to the right, thereby increasing the total length between the adjusting rod 8, the connecting rod 9, and the handle 10, thus increasing the lever arm when rotating the threaded seat 6, making it easier to rotate the threaded seat 6. Moving the connecting rod 9 to the left, thereby shortening the total length between the adjusting rod 8, the connecting rod 9, and the handle 10, preventing the adjusting rod 8, the connecting rod 9 from interfering with the handle 10. If the total length between the handles 10 is too long, it will affect the normal rotation of the handles 10. After the total length between the adjusting rod 8, the connecting rod 9 and the handle 10 is adjusted, reverse the fixing bolt 12 so that the fixing bolt 12 enters the corresponding limiting hole in the connecting rod 9, thereby fixing the total length between the adjusting rod 8, the connecting rod 9 and the handle 10. At this time, rotate the handle 10, thereby driving the threaded seat 6 to rotate, so that the threaded seat 6 moves towards the baffle 5, so that the threaded seat 6 contacts the baffle 5. At this time, the threaded seat 6 cannot move forward, so that the threaded seat 6 applies force to the threaded rod 4 and the external threaded nut 3. By applying rotational force, the external threaded nut 3 is restricted by the end plate body 2 and cannot rotate. This causes the external threaded nut 3 to convert the rotational force into a pulling force on the end plate body 2, thereby pulling the end plate body 2 out of the reverse osmosis membrane shell 1. This makes the device easier to reduce the manpower required to rotate the external threaded nut 3. At the same time, the total length between the connecting rod 9, the adjusting rod 8 and the handle 10 can be adjusted to ensure that the lever arm when rotating the threaded seat 6 can be increased without affecting the normal rotation of the handle 10. This makes it easier to rotate the handle 10 and improves the ease of use of the device.
