Description

Technical Field

[0001] The utility model relates to the technical field of air locks, in particular to an air lock that prevents air leakage. Background Art

[0002] The air lock is a device that is mainly used to discharge materials smoothly under pressure difference and prevent air leakage. It is usually used in pneumatic conveying systems to ensure the continuous discharge of materials while maintaining the air tightness of the system. The air lock has the characteristics of compact structure, good air tightness, continuous and reliable discharge, etc., and is suitable for a variety of industrial fields.

[0003] In Chinese utility model patent application No. CN202222172832.4, there is disclosed an air leakage-proof air shutoff. By arranging guide blades, elastic strips and rectangular grooves, the elastic strips of the guide blades are always against the inner wall of the outer shell when the guide blades rotate with the long rotating rod, thereby solving the problem of air leakage in the outer shell. By arranging a locking structure, the effect of direct plug-in installation and removal of the guide blades is achieved, the difficulty of installing and removing the guide blades is reduced, and the air shutoff fan is sealed, which can effectively improve the unloading efficiency.

[0004] Although the above patent realizes the function of assisting the air lock in use, the above patent has the following disadvantages when used: the impeller assembly of the above air lock for preventing air leakage is fixedly mounted on the long rotating rod when in use and cannot be removed. If one of the impeller assemblies is broken or damaged, the entire long rotating rod must be replaced, which causes waste and is inconvenient to use. Therefore, we propose an air lock for preventing air leakage. Utility Model Content

[0027] A leak-proof air lock comprises a shell 1, a feed port 4 is fixedly connected to the top of the shell 1, a discharge port 2 is fixedly connected to the bottom of the shell 1, a rotating rod 7 is rotatably connected to the inside of the shell 1, a mounting frame 10 is equidistantly fixedly connected to the outside of the rotating rod 7, an adjusting plate 11 is slidably connected to the inside of the mounting frame 10, a mounting block 14 is equidistantly fixedly connected to one side of the adjusting plate 11, the mounting block 14 is slidably connected to the mounting frame 10, an impeller blade 8 is provided on one side of the mounting frame 10, and mounting grooves 16 for use with the mounting block 14 are equidistantly opened inside the impeller blade 8, a sealing cover 3 is provided on one side of the shell 1, a positioning block 9 is symmetrically fixedly connected to the outside of the sealing cover 3, a connecting block 17 is slidably connected to the inside of the positioning block 9, an arc block 20 is fixedly connected to one side of the connecting block 17, and a feed port 4 is rotatably connected to the outside of the shell 10. A fixing block 22 is fixedly connected to one side of the discharge port 2, and a limiting groove 21 is provided inside the fixing block 22 for use with the arc block 20; when in use, the setting of the feed port 4 and the discharge port 2 facilitates feeding and discharging, and the rotation of the rotating rod 7 drives the mounting frame 10 to rotate, thereby driving the impeller blade 8 to rotate, which is convenient for the material guiding operation, and the movement of the adjusting plate 11 drives the mounting block 14 to move, so that the mounting block 14 moves into or out of the mounting groove 16, which is convenient for the rapid disassembly and assembly of the impeller blade 8, and the movement of the connecting block 17 drives the arc block 20 to move, so that the arc block 20 moves into the limiting groove 21, thereby limiting and fixing the position of the fixing block 22 to a certain extent, which is convenient for the subsequent installation and fixation of the sealing cover 3 by bolts.

[0028] Furthermore, a limiting rod 15 is symmetrically fixedly connected inside the mounting frame 10, and the adjustment plate 11 is slidably connected to the limiting rod 15. The setting of the limiting rod 15 can limit the movement of the adjustment plate 11 to prevent deviation.

[0029] Furthermore, the internal thread of the mounting frame 10 is connected with a threaded rod 13, which is rotatably connected to the adjustment plate 11. One end of the threaded rod 13 away from the adjustment plate 11 is fixedly connected with a handle, and the adjustment plate 11 is moved by the rotation of the threaded rod 13, thereby assisting the disassembly and assembly of the impeller blade 8.

[0030] Furthermore, a protective end cover 12 is threadedly connected to one side of the mounting frame 10, and the protective end cover 12 can be used to protect the handle.

[0031] Furthermore, a fixing rod 19 is fixedly connected inside the positioning block 9, and the connecting block 17 is slidably connected to the fixing rod 19. A spring 18 is provided between the connecting block 17 and the positioning block 9. The setting of the fixing rod 19 can limit the movement of the connecting block 17 to prevent deviation.

[0032] Furthermore, a first sealing ring 5 is provided on one side of the sealing cover 3, and a second sealing ring 6 is provided inside the sealing cover 3. The arrangement of the first sealing ring 5 and the second sealing ring 6 can enhance the sealing effect and prevent air leakage.

[0033] When in use, the first sealing ring 5 and the second sealing ring 6 can enhance the sealing effect and prevent air leakage. The rotation of the rotating rod 7 drives the mounting frame 10 to rotate, and then drives the impeller blade 8 to rotate, which is convenient for the material guiding operation. When the impeller blade 8 is damaged and needs to be replaced, the protective end cover 12 can be unscrewed, and the threaded rod 13 can be rotated. The rotation of the threaded rod 13 drives the adjusting plate 11 to move. The movement of the adjusting plate 11 can be limited by the setting of the limiting rod 15. The adjusting plate 11 drives the mounting block 14 to move out of the mounting groove 16, and the locking state of the impeller blade 8 is released. The impeller blade 8 can be removed and it is convenient for it to be replaced. Separate replacement is easy to operate. When installing the sealing cover 3, first make the fixing block 22 enter the interior of the positioning block 9. Since the arc block 20 is an arc, when the fixing block 22 enters the interior of the positioning block 9, it will squeeze and drive the arc block 20 to move. The arc block 20 drives the connecting block 17 to move, and the spring 18 is compressed. When the fixing block 22 enters the interior of the positioning block 9, the spring 18 drives the connecting block 17 to move and reset due to the elastic force, and then drives the arc block 20 to move into the interior of the limiting groove 21 through the connecting block 17, thereby limiting the position of the fixing block 22 to a certain extent, making it convenient to install and fix the sealing cover 3 through bolts later, and easy to use.
