Description

Technical Field

[0001] The utility model relates to the technical field of air locks, in particular to an air lock with an airtightness compensation function. Background Art

[0002] Airflow drying is widely used in tobacco shred production lines, and inlet and outlet airlocks are crucial components of this process. Traditional airlocks consist of a housing, rotor, and drive unit. Specifically, the housing is a special-shaped enclosure with open top and bottom flanges. A rotor with radial blades is rotatably connected to the inner walls of the housing, and the rotor input shaft is connected to the drive unit outside the housing. During installation, the top flange of the housing is first connected to the feed pipe, followed by the bottom flange of the housing to complete the basic assembly of the traditional airlock.

[0003] Although traditional inlet and outlet air locks can assist in completing the airflow drying process involved in tobacco shredding, the following defects still exist during use: there is an assembly gap in the traditional air lock during assembly. When in use, the inside of the traditional air lock will be filled with high-temperature gas. Since the thermal expansion coefficients of the various components that make up the traditional air lock are somewhat different, the fitting parts of the components in the air lock will wear out. For example, there will be varying degrees of wear at the rotating ends of the rotor and the shell. This wear will cause a gap to appear at the rotating contact point of the rotor and the shell, indirectly causing part of the gas inside the air lock to leak from the gap at the rotating contact point of the rotor and the shell when the air lock is operating. The gas and material in the air lock are not matched, and the gas-to-material ratio (gas-to-material ratio) does not match the process requirements.

[0004] Therefore, it is necessary to design and improve the existing air lock structure to solve the problem that after long-term use, the existing air lock structure will cause gaps to appear at the rotating contact points between the rotor in the air lock and the two ends of the air lock shell due to wear, resulting in part of the gas inside the air lock leaking from the gaps at the rotating contact points between the rotor and the shell when the air lock is operating, resulting in a mismatch between the gas-to-material (gas to material ratio) ratio and the process requirements.

DETAILED DESCRIPTION

[0040] like Figure 1-16In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] Example

[0042] Traditional air locks have an assembly gap during assembly. When in use, the inside of the traditional air lock will be filled with high-temperature gas. Since the thermal expansion coefficients of the various components that make up the traditional air lock are different, wear will occur at the fitting points of the components in the air lock. For example, wear will occur at the rotating points of the rotor and the shell. This wear will cause a gap to appear at the rotating contact point of the rotor and the shell, indirectly causing part of the gas inside the air lock to leak from the gap at the rotating contact point of the rotor and the shell when the air lock is operating. The gas and material in the air lock are not matched, and the gas-to-material ratio (gas-to-material ratio) does not match the process requirements.

[0043] Therefore, the present application proposes an air lock with an airtightness compensation function to solve the problem that after long-term use, the existing air lock structure will cause a gap to appear at the rotating contact point between the rotor in the air lock and the two ends of the air lock shell due to wear, resulting in part of the gas inside the air lock leaking from the gap at the rotating contact point between the rotor and the shell when the air lock is operating, and the gas-to-material (gas to material ratio) ratio does not match the process requirements.

[0044] For details, please refer to Figure 1 and Figure 2 , an air lock with airtightness compensation function, comprising a special-shaped shell 1, a rotating assembly 6 and a tensioning adjustment member 8; wherein the special-shaped shell 1 has a feed port 3, a rotating assembly accommodating space 4 and a discharge port 5, and the feed port 3, the rotating assembly accommodating space 4 and the discharge port 5 are interconnected from top to bottom; the two side walls of the special-shaped shell 1 are rotatably connected with part of the rotating assembly 6, and the part of the rotating assembly 6 is located in the rotating assembly accommodating space 4, and the two ends of the rotating assembly 6 are rotatably connected to the flange seats 7 detachably connected to the two outer side walls of the special-shaped shell 1; the inner wall of the flange seat 7 is connected to the fixed end of the tensioning adjustment member 8, and the active end of the tensioning adjustment member 8 movably conflicts with the seal 9 used to seal the rotating contact between the rotating assembly 6 and the side wall 1 of the special-shaped shell, and the seal 9 is movably connected to the two outer side walls of the special-shaped shell 1.

[0045] In actual use, when gaps of different widths appear at the rotating contact between the rotating component 6 and the special-shaped shell 1 due to wear, the tensioning adjustment members 8 on the two outer walls of the special-shaped shell 1 can be adjusted according to the pressure of the gas leakage at the gaps of different widths worn at the rotating contact between the rotating component 6 and the special-shaped shell 1, so that the tensioning adjustment members 8 apply different pressures to the seals 9 on the two outer walls of the special-shaped shell 1 for sealing the rotating contact between the rotating component 6 and the special-shaped shell 1. In this way, the seals 9 on the two outer walls of the special-shaped shell 1 will respectively block the gas leakage from the gaps worn at the rotating contact between the rotating component 6 and the special-shaped shell 1, thereby completing the sealing compensation for the gaps of different widths worn at the rotating contact between the rotating component 6 and the special-shaped shell 1. The overall airtightness of the air lock is further improved, and the gas-to-material (gas to material ratio) ratio can also match the process requirements.

[0046] See also Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 8 The tensioning adjustment member 8 for sealing the gap caused by wear at the rotating contact between the rotating component 6 and the special-shaped shell 1 includes a support 10, a screw 11, a spring 12, a first limiting bolt 13, a pressure block 14 and a movable pressure piece 15; wherein the support 10 is used to be connected to the inner wall of the flange seat 7 connected to the outer side wall of the special-shaped shell 1; the screw 11 is respectively connected to the support 10 and the sleeve 35 on the pressure block 14; the spring 12 is used to apply pressure to the pressure block 14 connected to the other end of the spring 12 under the interference of the nut threadedly connected to the screw 11; the pressure block 14 is used to apply the pressure it receives to the movable pressure piece 15, so that the movable pressure piece 15 moves axially; the movable pressure piece 15 is used to apply the pressure it receives to the seal 9 for sealing the rotating contact between the rotating component 6 and the special-shaped shell 1, so that the seal 9 can seal the gap caused by wear at the rotating contact between the rotating component 6 and the special-shaped shell 1.

[0047] Specifically, the outer wall of the top of the support 10 is detachably connected to the inner wall of the connecting flange seat 7 by screws, the bottom of the support 10 is connected to one end of the screw 11, and the rod section at the other end of the screw 11 is slidably connected to the sleeve 35 connected to the top of the pressing block 14. A spring 12 is sleeved on the outside of the screw 11 and the sleeve 35. One end of the spring 12 is in conflict with the nut threadedly connected to the screw 11, and the other end of the spring 12 is connected to the pressing block 14. The pressing block 14 is movably connected to the movable pressing piece 15 through the first limiting bolt 13, and the movable pressing piece 15 is movably in conflict with the seal 9 used to seal the rotating contact between the rotating component 6 and the side wall of the special-shaped shell 1.

[0048] In actual use, when the tensioning adjustment member 8 seals the gap between the rotating assembly 6 and the special-shaped shell 1 at the rotational contact point between the sealing member 9 and the rotating assembly 6, the nut threadedly connected to the screw 11 can be screwed to cause the nut to press against one end of the spring 12 which is sleeved on the screw 11 and the sleeve 35. After the spring 12 is pressed against, the spring 12 connected to the pressing block 14 drives the movable pressing member 15 to move or press toward the sealing member 9 used to seal the rotational contact point between the rotating assembly 6 and the special-shaped shell 1 through the pressing block 14. In this way, the squeezed sealing member 9 seals the gap between the rotating assembly 6 and the special-shaped shell 1 at the rotational contact point due to wear.

[0049] It should be noted that, in order to make the nut more stably resist the spring 12, the outer ring diameter of the spring 12 is smaller than the diameter of the nut.

[0050] It should be noted that in order to allow the spring 12 to move more smoothly along the surface of the screw 11 and the sleeve 35 when in contact with the nut threadedly connected to the screw 11, the inner ring diameter of the spring 12 is larger than the outermost ring diameter of the screw 11 and the sleeve 35.

[0051] It should be noted that the sleeve 35 is a hollow cylindrical structure with one end open, and the light rod section at one end of the screw 11 that is slidingly connected to the sleeve 35 is also sleeved with a slip ring. The slip ring on the light rod is slidably adapted to the inner wall of the sleeve cavity, and the slip ring is limitedly fitted with a limit ring on the inner wall of the cavity near the open end of the sleeve, that is, the inner ring diameter of the limit ring is smaller than the inner ring diameter of the slip ring, wherein the light rod and the limit ring are slidably fitted.

[0052] See also Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The movable pressure piece 15 for squeezing the seal 9 is a pressure ring formed by a plurality of pressure blocks 16 clamped together, wherein each pressure block 16 is respectively provided with a first threaded hole, and the first threaded hole is threadedly connected to the first limiting bolt 13 passing through the first through hole 17 on the pressing block 14, and the limiting nut on the first limiting bolt 13 is limitedly matched with the pressing block 14.

[0053] In actual use, after the spring 12 is squeezed and resisted by the nut, the spring 12 connected to the pressing block 14 drives the movable pressing piece 15 to squeeze the seal 9 through the pressing block 14. The pressing block 14 connected to the spring 12 will move along the first limiting bolt 13 toward the pressing block 16 on the side of the pressing block 14, and the movable pressing piece 15 that is squeezed or resisted will indirectly squeeze the seal 9.

[0054] It should be noted that the diameter of the first through hole 17 is larger than the diameter of the outer ring of the first limiting bolt 13 , so that the first limiting bolt 13 can pass through the first through hole 17 on the pressing block 14 .

[0055] It should be noted that, in order to prevent the movable pressure piece 15 from being severely pulled at different parts of the movable pressure piece 15 when it is subjected to different pre-tightening forces of the pressing block 14, the movable pressure piece 15 is a pressure ring formed by a plurality of pressure blocks 16 that are mutually clamped. In this way, when the movable pressure piece 15 is subjected to different pre-tightening forces of the pressing block 14, since the movable pressure piece 15 is formed by a plurality of pressure blocks 16 that are mutually clamped, the pulling applied to each pressure block 16 becomes smaller.

[0056] See also Figure 5 、 Figure 7 and Figure 8 The sealing member 9 for sealing the rotating contact between the rotating assembly 6 and the special-shaped shell 1 includes a sealing gasket ring block 18 and a fixed ring block 19; wherein, the sealing gasket ring block 18 is used to seal the gap at the rotating contact between the rotating assembly 6 and the special-shaped shell 1; the fixed ring block 19 is used to movably connect the sealing gasket ring block 18 with the inner platform ring 21 on the flange 20.

[0057] Specifically, the annular sealing gasket ring block 18 is in movably contact with the movable pressure piece 15, and the annular fixed ring block 19 is movably connected to the inner ring 21 on the flange 20 connected to the two side walls of the special-shaped shell 1 through the second limiting bolt 36 and the sealing gasket ring block 18. The sealing gasket ring block 18 is located at the rotational contact point between the rotating assembly 6 and the side wall of the special-shaped shell 1.

[0058] In actual use, when the squeezed sealing gasket ring block 18 contacts and seals the rotating contact point between the rotating component 6 and the special-shaped shell 1, the squeezed sealing gasket ring block 18 will move along the second limiting bolt 36 toward the rotating contact point between the rotating component 6 and the special-shaped shell 1 and contact to seal the gap between the rotating component 6 and the special-shaped shell 1.

[0059] It should be noted that the nut in the second limiting bolt 36 and the fixing ring block 19 both limit the sealing ring block 18 .

[0060] It should be noted that in order to achieve the aforementioned movable connection between the fixing ring block 19 and the inner collar 21 on the flange 20 connected to the two side walls of the special-shaped housing 1 through the second limiting bolt 36 and the sealing gasket ring block 18, a second through hole 22 is respectively provided on the sealing gasket ring block 18 and the fixing ring block 19. The limiting nut in the second limiting bolt 36 is limitedly engaged with the fixing ring block 19. The second limiting bolt 36 passes through the second through hole 22 provided in the fixing ring block 19 and the sealing gasket ring block 18 and is threadedly connected to the second threaded hole provided in the inner collar 21 of the flange 20 connected to the two side walls of the special-shaped housing 1. The diameter of the second through hole 22 provided in the sealing gasket ring block 18 and the fixing ring block 19 is larger than the outer diameter of the bolt in the second limiting bolt 36.

[0061] It should be noted that the sealing gasket ring block 18 is a well-known consumable part, and is generally replaced regularly.

[0062] See also Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14 The rotating assembly 6 that is in rotational contact with the special-shaped shell 1 includes a wear-resistant ring block 23, a rotating turntable 24, a connecting shaft 25, a rotating blade 26 and a rotating shaft 27; wherein, the wear-resistant ring block 23 is outer-engaged on the rotating turntable 24 (the wear-resistant ring block 23 and the rotating turntable 24 are connected as one body) to reduce the wear of the rotating turntable 24; the connecting shaft 25 is used as a base for connecting the rotating blade 26; the rotating turntable 24 is used as a base for connecting the connecting shaft 25 and the rotating shaft 27; the rotating shaft 27 is used to be connected to an external drive source to drive the rotating blade 26 to rotate.

[0063] Specifically, the wear-resistant ring blocks 23 are rotatably connected to the inner walls of the inner platform rings 21 in the flanges 20 installed at the open ends of the two side walls of the special-shaped shell 1. The sealing gasket ring block 18 is located on one side of the rotational contact between the wear-resistant ring block 23 and the inner wall of the inner platform ring 21 and movably interferes with it. The wear-resistant ring blocks 23 are respectively outermostly mounted on two rotating turntables 24. The outer side walls of the two rotating turntables 24 are respectively provided with rotating shafts 27 rotatably connected to the flange seat 7. A connecting shaft 25 with rotating blades 26 is connected between the inner side walls of the two rotating turntables 24. The connecting shaft 25 and the rotating blades 26 are both located in the rotating component accommodating space 4 of the special-shaped shell 1.

[0064] In actual use, when the rotating assembly 6 rotates on the special-shaped shell 1, the wear of the rotating turntable 24 is further reduced because the wear-resistant ring block 23 in the rotating assembly 6 is located at the rotating contact point between the rotating turntable 24 and the flange 20 at the open ends of the two side walls of the special-shaped shell 1.

[0065] It should be noted that in order to provide the rotating assembly 6 with the power required for rotation, an air lock with airtightness compensation function also includes a motor 30, and the driving bevel gear on the output shaft of the motor 30 is engaged with the driven bevel gear on the rotating shaft 27 connected to the flange seat 7 for rotation.

[0066] It should be noted that, in order to provide support for the motor 30, an air lock with an airtightness compensation function also includes a connecting bracket 31, which includes a first connecting arm 32, a connecting plate 33 and a second connecting arm 34. One end of the first connecting arm 32 is connected to the outer wall of the special-shaped shell 1, and the other end of the first connecting arm 32 is connected to one end of the second connecting arm 34 through the connecting plate 33, and the other end of the second connecting arm 34 is connected to the outer wall of the motor 30.

[0067] See also Figure 15 、 Figure 16and Figure 10 In order to facilitate the connection between the flange seat 7 and the side wall of the special-shaped shell 1, the flange 20 installed at the open end of the two side walls of the special-shaped shell 1 also has an outer ring 28. The outer ring 28 is connected to the inner ring 21 as a whole. The outer ring 28 is detachably connected to the wing edge of the flange seat 7 through a bolt assembly.

[0068] In actual use, when the flange seat 7 is assembled with the special-shaped shell 1, the flange seat 7 can be connected to the outer ring 28 of the flange 20 at the open end of the two side walls of the special-shaped shell 1 through a bolt assembly to install the flange seat 7 on the two side walls of the special-shaped shell 1.

[0069] When the flange seat 7 is disassembled from the special-shaped shell 1 , the bolt assembly can be detached from the flange seat 7 and the flanges 20 on both side walls of the special-shaped shell 1 to remove the flange seat 7 from the two side walls of the special-shaped shell 1 .

[0070] It should be noted that the inner ring 21 and the outer ring 28 of the flange 20 at the open ends of the two side walls of the special-shaped shell 1 are connected as a whole to form a flange base. The space enclosed by the inner ring 21 is the inner cavity of the flange 20, and the inner cavity is the cavity in which the wear-resistant ring block 23 on the rotating turntable 24 rotates and contacts.
