Description

Technical Field

[0001] This utility model relates to the technical field of reverse osmosis membrane maintenance equipment, and in particular to a device for disassembling the plug of a reverse osmosis membrane pressure vessel. Background Technology

[0002] A reverse osmosis membrane is an artificial semi-permeable membrane with specific characteristics, mimicking the support of a biological semi-permeable membrane. It is the core component of reverse osmosis technology. The principle of reverse osmosis is to separate water from other substances by applying pressure higher than the osmotic pressure of the solution, based on the fact that other substances cannot pass through the semi-permeable membrane. The membrane pore size of a reverse osmosis membrane is extremely small, thus effectively removing dissolved salts, colloids, microorganisms, and organic matter from water. As the reverse osmosis membrane is used over time, its performance deteriorates due to contaminant accumulation and aging. Therefore, regular cleaning and replacement of the reverse osmosis membrane pressure vessel are necessary. Disassembling the plug of the reverse osmosis membrane pressure vessel is the first step in these maintenance procedures. Its structure is as follows: Figure 1 and Figure 2 As shown. The reverse osmosis membrane pressure vessel is equipped with a plug, which has multiple threaded holes.

[0003] Currently, the removal of plugs from reverse osmosis membrane pressure vessels is generally done manually. Operators use simple tools such as wrenches and pry bars to pull the plugs off the pressure vessel by applying direct force. This method requires a significant amount of physical strength. Especially for large reverse osmosis membrane equipment, the disassembly operation is time-consuming and labor-intensive, severely impacting the efficiency of maintenance work. Summary of the Invention

[0004] To address the problem of time-consuming and labor-intensive disassembly of plugs in existing reverse osmosis membrane pressure vessels, this invention provides a device for disassembling plugs in reverse osmosis membrane pressure vessels. Utilizing the principle of a force-saving lever structure, the device is fixed in place by a fixing device. Pressing the lever causes the pull-out device to remove the plug from the reverse osmosis membrane pressure vessel, saving physical effort and improving the efficiency of maintenance operations.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A device for disassembling a plug on a reverse osmosis membrane pressure vessel includes a connecting rod, a fixing device, and a pulling mechanism. The pulling mechanism is mounted on the connecting rod and includes a fixing seat and a pressure rod. The fixing seat is fixed to the connecting rod, and the pressure rod is rotatably connected to the fixing seat. One end of the pressure rod is suspended in the air, and the other end is connected to a pulling device. The length of the suspended end of the pressure rod is greater than the length of the other end. The pulling device is connected to the plug at the end of the reverse osmosis membrane pressure vessel. The fixing device is mounted on the connecting rod. Utilizing the principle of a force-saving lever structure, the fixing device is snapped onto the side wall of the plug on the reverse osmosis membrane pressure vessel. Pressing the pressure rod causes the pulling device to pull out the plug from the reverse osmosis membrane pressure vessel, saving physical effort and improving the efficiency of maintenance operations.

[0007] Furthermore, the fixing seat has a "п"-shaped structure, with a groove in the middle of the fixing seat that mates with the connecting rod. The groove of the fixing seat is snapped into the outer wall of the middle part of the connecting rod, and the two ends of the opening of the fixing seat are connected by bolts.

[0008] Furthermore, a connecting seat is fixed to the fixed base. The connecting seat has the same structure as the fixed base, and a connecting shaft is fixed to the connecting seat. One end of the connecting shaft is fixed to the connecting seat, and the other end is provided with a clamping seat for limiting movement. The pressure rod is rotatably connected to the connecting shaft between the connecting seat and the clamping seat. The connection seat and clamping seat facilitate the rotation of the pressure rod and prevent the pressure rod from moving in the axial direction of the connecting shaft, thus affecting the performance.

[0009] Furthermore, the pull-out device includes a plug connector and a support rod. One end of the support rod is rotatably connected to the pressure rod, and the other end is fixed with a hook. The plug connector is disposed on the plug of the reverse osmosis membrane pressure vessel and hooked onto the hook. The pull-out device facilitates the removal of the plug and makes disassembly and use convenient.

[0010] Furthermore, the plug connector is a lifting eye bolt.

[0011] Furthermore, there are two fixing devices, each located at one end of the connecting rod. Each fixing device includes a limiting rod and a support base. The support base is slidably connected to the connecting rod, and at least two limiting rods are fixed on the support base. These fixing devices are snapped into place on the inner and outer sides of the plug sidewall to prevent the connecting rod and pulling mechanism from slipping during use and affecting disassembly.

[0012] Furthermore, the support base has the same structure as the fixed base. The support base has a groove in the middle that mates with the connecting rod. The two open ends of the support base are connected by bolts, and the limiting rod is threadedly connected to the support base. The support base and the connecting rod are slidably connected, facilitating adjustment of the distance between the two fixing devices to accommodate plugs of different specifications of reverse osmosis membrane pressure vessels, while also improving the stability of the fixing devices when snapped onto the side wall of the reverse osmosis membrane pressure vessel.

[0013] The beneficial effects of this utility model through the above technical solution are:

[0014] This invention utilizes the principle of lever-saving, employing a fixing device that is snapped onto the inner and outer sides of the plug sidewall of the reverse osmosis membrane pressure vessel. Pressing the lever causes the pull-out device to remove the plug, saving manual labor while ensuring the efficiency of maintenance operations. The fixing device also ensures the pulling mechanism is secured during operation, preventing it from slipping and affecting its performance. Attached Figure Description

[0022] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0023] like Figures 3-6As shown, a disassembly device for a reverse osmosis membrane pressure vessel plug includes a connecting rod 5, a fixing device, and a pulling mechanism 4. The pulling mechanism 4 is mounted on the connecting rod 5 and includes a fixing seat 7 and a pressure rod 11. The fixing seat 7 has a "п"-shaped structure, with a groove in the middle that mates with the connecting rod 5. The groove of the fixing seat 7 is engaged with the outer wall of the middle part of the connecting rod 5, and the two ends of the open end of the fixing seat 7 are connected by bolts. After the bolts are tightened, the fixing seat 7 is fixedly installed on the connecting rod 5.

[0024] The pressure rod 11 is rotatably connected to the fixed base 7. Specifically, a connecting seat 9 is fixed on the fixed base 7. The connecting seat 9 has the same structure as the fixed base 7 and is connected to the fixed base 7 by bolts. A connecting shaft 10 is fixed on the connecting seat 9. A groove is opened in the middle of the connecting seat 9 to mate with the connecting shaft 10. One end of the connecting shaft 10 is fixed to the connecting seat 9, and a clamping seat 14 for limiting movement is provided on the other end. This prevents the pressure rod 11 from moving in the axial direction of the connecting shaft 10, which would affect the performance. The pressure rod 11 is located on the connecting shaft 10 between the connecting seat 9 and the clamping seat 14, and the pressure rod 11 is rotatably connected to the connecting shaft 10. One end of the pressure rod 11 is suspended, and the other end is connected to a pull-out device. The length of the suspended end of the pressure rod 11 is greater than the length of the other end. The pull-out device is connected to the plug 2 at the end of the reverse osmosis membrane pressure vessel 1.

[0025] The pull-out device includes a support rod 12 and a plug connector. One end of the support rod 12 is rotatably connected to the pressure rod 11, and the other end of the support rod 12 is fixed with a hook 13. The plug connector is a lifting eye bolt 3, and the hook 13 on the support rod 12 hooks onto the lifting eye of the lifting eye bolt 3. When in use, the lifting eye bolt 3 is fixed in one of the threaded holes of the plug 2.

[0026] Two fixing devices are provided, one at each end of the connecting rod 5. Each fixing device includes a limiting rod 8 and a support base 6. The support base 6 is slidably connected to the connecting rod 5, facilitating quick adjustment of the distance between the two fixing devices so that the limiting rod 8 can be tangentially engaged and fixed to the side wall of the reverse osmosis membrane pressure vessel 1 of different specifications. Specifically, the support base 6 has the same structure as the fixing base 7. The support base 6 has a groove in the middle that mates with the connecting rod 5. The groove of the support base 6 engages with the outer wall of the connecting rod 5, and the two open ends of the support base 6 are connected by bolts. Two limiting rods 8 are provided, one at each end of the support base 6, and the limiting rods 8 are threadedly connected to the support base 6. When in use, the limiting rods 8 of the two support seats 6 are clamped on the inner and outer sides of the side wall of the reverse osmosis membrane pressure vessel 1. When the pressure rod 11 is pressed down, the connecting rod 5 is squeezed upward by force, so that the limiting rod 8 and the support seat 6 are clamped on the side wall of the reverse osmosis membrane pressure vessel, preventing the connecting rod 5 and the pulling mechanism 4 from slipping down as a whole, affecting disassembly, and improving the safety of use during disassembly.

[0027] When in use, thread the lifting eye bolt 3 into one of the threaded holes of the plug 2 of the reverse osmosis membrane pressure vessel 1, adjust the distance between the two support seats 6, and respectively lock the two limiting rods 8 of the two support seats 6 onto the inner and outer sides of the side wall of the reverse osmosis membrane pressure vessel 1. Figure 5 and Figure 6 As shown, when the pressure rod 11 is pressed down, the connecting rod 5 is squeezed upwards, thereby causing the limiting rod 8 and the support seat 6 to clamp onto the side wall of the reverse osmosis membrane pressure vessel, and the entire device moves and slides down. Rotate the orientation of the lifting ring of the lifting ring bolt 3, and at the same time adjust the position of the support rod 12 so that the hook 13 can hook onto the lifting ring of the lifting ring bolt 3. Through the principle of the force-saving lever structure, pressing the suspended end of the pressure rod 11 causes the other end of the pressure rod 11 to rotate and drive the support rod 12 to move. The support rod 12 drives the hook 13 to move, and the hook 13 drives the lifting ring bolt 3 and the plug 2 fixed to the lifting ring bolt 3 to pull the plug 2 out of the reverse osmosis membrane pressure vessel 1 under the action of force.
