[0002] In chemical production processes, the removal of oil and impurities from liquid ammonia is a crucial step in ensuring product quality and production safety. Currently, liquid ammonia oil and impurity removal devices often use sintered metal felt filter elements to filter liquid ammonia and remove impurities. Sintered metal felt filter elements have advantages such as high filtration accuracy and high strength, and are widely used in the field of liquid ammonia impurity removal.

[0003] However, existing liquid ammonia oil and impurity removal devices have significant drawbacks in actual use. After prolonged use, the filtration efficiency of the metal sintered felt filter element decreases due to impurity blockage, requiring regular replacement. However, the existing devices have complex installation structures and cumbersome disassembly processes for the metal sintered felt filter element, often requiring multiple tools and consuming a lot of time. Furthermore, the operation process can easily lead to filter element damage or seal failure, which not only increases maintenance costs but also affects production efficiency. In addition, the complex disassembly and assembly process also places a heavy workload on operators and poses certain safety hazards. Therefore, improvements are needed. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 7 As shown, this utility model provides an integrated device for oil and impurity removal and gasification of liquid ammonia, comprising:

[0030] Liquid inlet pipe 1, with a metal sintered felt filter element 2 at the bottom end of liquid inlet pipe 1;

[0031] A connecting mechanism is provided on the outer surface of the inlet pipe 1;

[0032] The connecting mechanism includes a threaded sleeve 3, the inside of which is fixedly sleeved with the outer surface of the inlet pipe 1. A rotating sleeve 4 is threadedly sleeved on the outer surface of the threaded sleeve 3. A first turning ring 5 is fixedly sleeved on the outer surface of the rotating sleeve 4. A moving ring 6 is movably sleeved on the outer surface of the rotating sleeve 4. A threaded block 7 is fixedly installed on the outer surface of the moving ring 6. A rotating ring 8 is threadedly sleeved on the outer surface of the threaded block 7. A second turning ring 9 is fixedly sleeved on the outer surface of the rotating ring 8. A rotating block 10 is movably sleeved inside the rotating ring 8. An arc-shaped block 30 and a first hinge block 11 are fixedly installed on the outer surface of the rotating block 10. A second hinge block 12 is hinged on the first hinge block 11. The outer surface of the second hinge block 12 is fixedly connected to the outer surface of the moving ring 6.

[0033] Due to the design of the first turning ring 5, when the operator turns the first turning ring 5, it will drive the rotating sleeve 4 to rotate. Since the inside of the rotating sleeve 4 is threadedly connected to the outer surface of the threaded sleeve 3, when the rotating sleeve 4 rotates along the outer surface of the threaded sleeve 3, it will simultaneously move downwards. Since the inside of the moving ring 6 is movably connected to the outer surface of the rotating sleeve 4, the moving ring 6 will move downwards under the drive of the rotating sleeve 4. At this time, the moving ring 6 will simultaneously drive the threaded block 7 and the second hinge block 12 to move downwards. At this time, the threaded block 7 will drive the rotating ring 8 and the second turning ring 9 to move downwards. At the same time, the second hinge block 12 will drive the rotating block 10 to move downwards through the first hinge block 11. During this process, the metal sintered felt filter element 2 will move downwards under the drive of the rotating block 10, causing the metal sintered felt filter element 2 to move downwards. The top of the felt filter element 2 is separated from the bottom of the inlet pipe 1. When the rotating sleeve 4 moves to the bottom of the outer surface of the threaded sleeve 3, the operator turns the second turning ring 9. The rotating ring 8 will rotate under the drive of the second turning ring 9. Since the inside of the rotating ring 8 is threadedly connected to the outer surface of the threaded block 7, the rotating ring 8 will move upward along the outer surface of the threaded block 7 while rotating. Then, the inside of the rotating ring 8 will release its contact with the rotating block 10 during the upward movement. At this time, the rotating block 10 will be able to rotate around the hinge point of the first hinge block 11 and the second hinge block 12 as the axis. When the four rotating blocks 10 rotate and unfold, the four rotating blocks 10 will release the fixing effect on the metal sintered felt filter element 2, so that the operator can remove the metal sintered felt filter element 2.

[0034] The outer surface of the liquid inlet pipe 1 is fixedly fitted with a top cover 14, the top of the top cover 14 is fixedly fitted with a gas delivery pipe 15, the bottom of the top cover 14 is fitted with a vaporization tank 16, the top of the vaporization tank 16 is abutted by a sealing ring, and the sealing ring is fixedly fitted with the bottom of the top cover 14.

[0035] Due to the design of the vaporization tank 16, the filtered liquid ammonia can enter the interior of the vaporization tank 16 for vaporization. Due to the design of the gas delivery pipe 15, the vaporized ammonia gas can be discharged from the interior of the vaporization tank 16 through the gas delivery pipe 15. Due to the sealing ring between the vaporization tank 16 and the top cover 14, the sealing between the vaporization tank 16 and the top cover 14 can be enhanced.

[0036] The top of the top cover 14 is fixedly mounted with a conductive ring 17, and the bottom of the conductive ring 17 is fixedly mounted with a heating wire 18.

[0037] When the operator powers on the conductive ring 17, the heating wire 18 will heat the liquid ammonia inside the vaporization tank 16, thereby causing the liquid ammonia to boil and vaporize.

[0038] Among them, a fixing block 19 is fixedly installed at the top of the liquid inlet pipe 1, a screw 20 is interlocked inside the fixing block 19, and a screwing block 21 is fixedly installed at the top of the screw 20.

[0039] Because the screw 20 is internally and movably connected to the fixed block 19, when the operator turns the turning block 21, the screw 20 will rotate along the inside of the fixed block 19.

[0040] Among them, the outer surface of the screw 20 is threaded with a moving plate 22, and the inside of the moving plate 22 is movably sleeved with a vertical rod 23, the bottom end of the vertical rod 23 being fixedly connected to the top end of the top cover 14.

[0041] Since the moving plate 22 is threadedly connected to the outer surface of the screw 20, when the screw 20 rotates, it will drive the moving plate 22 to move up and down along the outer surface of the vertical rod 23.

[0042] Among them, a round rod 24 is movably sleeved inside the end of the moving plate 22 away from the screw 20, and a pull rod 25 is fixedly installed on the outer surface of the round rod 24.

[0043] Because the round rod 24 and the screw rod 20 are movably connected, the pull rod 25 can rotate around the round rod 24 as the axis.

[0044] The outer surface of the pull rod 25 abuts against the buckle 26, and the outer surface of the buckle 26 is fixedly connected to the outer surface of the gasification barrel 16.

[0045] When the lever 25 is fastened to the buckle 26, it will fix the connection between the top cover 14 and the gasification tank 16.

[0046] The top cover 14 has a fixed plate 27 fixedly installed on its outer surface, a base frame 28 fixedly installed at the bottom end of the fixed plate 27, and a reinforcing rod 29 fixedly installed on the base frame 28.

[0047] The design of the fixing plate 27 and the base frame 28 provides good support for the whole device, allowing it to be placed stably on the ground. The design of the reinforcing rod 29 enhances the structural strength of the base frame 28.

[0048] Among them, a gasket 13 is fixedly sleeved at the bottom end of the liquid inlet pipe 1, and the gasket 13 abuts against the top end of the metal sintered felt filter element 2.

[0049] Due to the design of the gasket 13, the sealing between the inlet pipe 1 and the metal sintered felt filter element 2 will be enhanced.

[0050] Working principle and usage process of this utility model:

[0051] When the operator needs to remove impurities and vaporize liquid ammonia, the operator guides the liquid ammonia through the inlet pipe 1 into the interior of the sintered metal felt filter element 2. Due to the design of the sintered metal felt filter element 2, it can remove impurities from the liquid ammonia. The filtered liquid ammonia then flows into the vaporization tank 16. At this time, the operator energizes the conductive ring 17, and the heating wire 18 heats the liquid ammonia so that it boils and vaporizes into ammonia gas. Then, this ammonia gas will move out of the interior of the vaporization tank 16 through the gas delivery pipe 15.

[0052] When the operator needs to replace the metal sintered felt filter element 2, the operator first turns the four turning blocks 21 one by one. At this time, the turning blocks 21 will drive the screw 20 to rotate along the inside of the fixed block 19. Since the outer surface of the screw 20 is connected to the internal thread of the moving plate 22, when the screw 20 rotates, it will drive the moving plate 22 to move downward along the outer surface of the vertical rod 23. At this time, the moving plate 22 will drive the pull rod 25 to move downward through the round rod 24. When the bottom end of the pull rod 25 is released from contact with the buckle 26 during the downward movement, the operator will then turn the pull rod 25 to rotate around the round rod 24. When the pull rod 25 rotates to the top of the buckle 26, the pull rod 25 will no longer be able to block the movement of the gasification tank 16 through the buckle 26, allowing the operator to remove the gasification tank 16 from the bottom of the top cover 14 for subsequent replacement of the metal sintered felt filter element 2.

[0053] Next, the operator turns the first turning ring 5. This causes the rotating sleeve 4 to rotate along the outer surface of the threaded sleeve 3. Since the inside of the rotating sleeve 4 is threadedly connected to the outer surface of the threaded sleeve 3, as the rotating sleeve 4 rotates, it moves downwards along the outer surface of the threaded sleeve 3. At this time, the rotating sleeve 4, through the moving ring 6, causes the threaded block 7 and the second hinge block 12 to move downwards. The threaded block 7 then causes the rotating ring 8 and the second turning ring 9 to move downwards. Simultaneously, the second hinge block 12, through the first hinge block 11, causes the rotating block 10 to move downwards. The entire metal sintered felt filter element 2 moves downwards under the influence of the rotating block 10. When the rotating sleeve 4 reaches the bottom of the outer surface of the threaded sleeve 3, the operator turns the second turning ring 5... When ring 9 is turned, the second turning ring 9 will drive the rotating ring 8 to rotate. Since the inside of the rotating ring 8 is threadedly connected to the outer surface of the threaded block 7, when the rotating ring 8 rotates, it will move upward along the outer surface of the threaded block 7. Then, the inside of the rotating ring 8 will release its contact with the four rotating blocks 10 during the upward movement. At this time, the rotating ring 8 will no longer be able to block the rotating blocks 10. At this time, the operator will turn the four rotating blocks 10 so that the four rotating blocks 10 rotate around the hinge point of the four first hinge blocks 11 and the four second hinge blocks 12 as the axis. Then, the four rotating blocks 10 will become unfolded during the rotation, thereby releasing the fixing effect on the metal sintered felt filter element 2, so that the operator can remove the metal sintered felt filter element 2.

[0054] After the operator has cleaned the metal sintered felt filter element 2, the operator moves the four rotating blocks 10 again to unfold them. The operator then places the top of the metal sintered felt filter element 2 between the four rotating blocks 10. Next, the operator moves the four rotating blocks 10 in the opposite direction to close them. At this point, the four rotating blocks 10 will provide some fixation for the metal sintered felt filter element 2. After the four rotating blocks 10 are closed, the operator twists the second twisting ring 9 in the opposite direction, causing the rotating ring 8 to move downwards. The inside of the rotating ring 8 will then fit over the outer surface of the four rotating blocks 10 during this movement, thus locking the four rotating blocks 10 in place. The four rotating blocks 10 maintain the fixed effect on the sintered metal felt filter element 2. Then, the operator turns the first turning ring 5 in the opposite direction, causing the rotating sleeve 4 to move upward as a whole. During this process, the four rotating blocks 10 will drive the sintered metal felt filter element 2 to move upward. Subsequently, the top of the sintered metal felt filter element 2 will contact the bottom of the liquid inlet pipe 1 during the upward movement. If the four rotating blocks 10 continue to move upward, they will apply a pulling force to the sintered metal felt filter element 2, thereby making the connection between the sintered metal felt filter element 2 and the liquid inlet pipe 1 tighter, thus completing the assembly of the sintered metal felt filter element 2 and realizing the function of convenient assembly and disassembly of the sintered metal felt filter element 2.
