[0030] The following is a further detailed description of the present application in conjunction with specific drawings. In the description of this embodiment, unless otherwise specified, the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the present application must have a specific orientation, be constructed and operated in a specific orientation, so it should not be construed as a limitation to the present application.
[0031] As Figures 1-3 shown, a pressure chamber barrel with a novel door ring structure provided by the present utility model mainly includes a chamber barrel body 100, a chamber barrel door ring 103, and a chamber barrel door 105. Specifically, as Figure 7 shown, the chamber barrel body 100 is provided with a first cavity 102. In this embodiment, the chamber barrel body 100 is a cylindrical structure with a thin wall. An opening 1021 is provided on one side of the chamber barrel body 100, and a mounting base 101 is provided on the side of the opening 1021 of the chamber barrel body 100 for the detachable installation of the chamber barrel door ring 103; the chamber barrel door ring 103 is an integral structure, and the chamber barrel door ring 103 is detachably arranged on the mounting base 101. A first convex clamping structure is provided between the mounting base 101 and the chamber barrel door ring 103, and the chamber barrel door ring 103 is rotatably arranged on the mounting base 101 through the first convex clamping structure. A first relief groove 1031 is provided on the outer side of the chamber barrel door ring 103 (i.e., the side away from the chamber barrel body 100); the chamber barrel door 105 is movably arranged on the side of the opening 1021 of the chamber barrel body 100, and the chamber barrel door 105 can seal the opening 1021 of the chamber barrel body 100. A second clamping boss 1051 is provided on the edge of the chamber barrel door 105. As Figure 5As shown, the size and number of the second clamping bosses 1051 are adapted to those of the first relief grooves 1031. In this embodiment, both are multiple. The second clamping bosses 1051 can be disengaged from the barrel body 100 through the second relief grooves 1035. Specifically, when the second clamping bosses 1051 correspond to the first relief grooves 1031 in position, the barrel door 105 can perform reciprocating linear movement along the axis where the barrel body 100 is located, realizing the disengagement of the barrel door 105 from the barrel body 100 or the sealing of the opening 1021 of the barrel body 100 by the barrel door 105.
[0032] In this application, by configuring the barrel door ring 103 into an integral structure and arranging a first convex clamping structure between the barrel door ring 103 and the mounting base 101, the barrel door ring 103 is rotatably arranged on the mounting base 101 through the first convex clamping structure. At the same time, the integral structure of the barrel door ring 103 prevents the barrel door ring 103 from deforming under stress, so that the barrel door ring 103 does not get stuck when rotating around the mounting base 101, further reducing the equipment failure rate.
[0033] In one embodiment, as Figure 4 and Figure 6 shown, the first convex clamping structure includes a first clamping boss arranged on the barrel door ring 103 and a first clamping groove 1011 arranged on the mounting base 101. The first clamping boss is adapted in size to the first clamping groove 1011. The first clamping boss is clamped in the first clamping groove 1011 and they are concentrically arranged. By rotating the first clamping boss in the first clamping groove 1011, the barrel door ring 103 is driven to rotate relative to the mounting base 101. In this embodiment, since the first clamping boss needs to rotate, the first clamping boss is a circular ring-shaped protrusion structure, that is, a regular cylindrical ring-shaped structure, and the first clamping groove is a matching cylindrical ring-shaped groove structure.
[0034] Optionally, as another variant implementation manner of this embodiment, the first clamping boss can also be arranged on the mounting base 101, and the first clamping groove 1011 is correspondingly arranged on the barrel door ring 103, which can also realize the rotatable arrangement of the barrel door ring 103 around the mounting base 101.
[0035] In one embodiment, with reference to Figure 3 、 Figure 4 and Figure 6, in order to facilitate the assembly of the drum door ring 103 on the mounting base 101 and facilitate the repair and replacement of the drum door ring 103, a plurality of second relief grooves 1035 are formed in the first clamping boss. The plurality of second relief grooves 1035 evenly divide the first clamping boss into a plurality of first clamping units 1034. A plurality of third relief grooves 1013 are provided on the side wall of the first clamping groove 1011. The plurality of third relief grooves 1013 divide the side wall of the first clamping groove 1011 into a plurality of evenly distributed first abutting units 1012. The first abutting units 1012 are arranged on the side close to the drum door 105. The size of the second relief groove 1035 is adapted to the size of the first abutting unit 1012, and the size of the third relief groove 1013 is adapted to the size of the first clamping unit 1034. When the first clamping unit 1034 corresponds to the third relief groove 1013 or the first abutting unit 1012 corresponds to the second relief groove 1035, the drum door ring 103 can be translated out of the first clamping groove 1011 along the axial direction of the drum body 100 for disassembly, or the drum door ring 103 can be assembled with the mounting base 101.
[0036] In one embodiment, in order to facilitate the installation and disassembly between the drum door ring 103 and the mounting base 101, the second arc length where the second relief groove 1035 is located is greater than the first arc length where the first abutting unit 1012 is located. When the second relief groove 1035 of the drum door ring 103 passes through the first abutting unit 1012 on the mounting base 101, a preset gap is provided between the first clamping unit 1035 and the first abutting unit 1012. By leaving the preset gap, the requirement for the relative position accuracy of the first clamping unit 1035 of the drum door ring 103 relative to the third relief groove 1013 of the mounting base 101 is reduced, making the installation and disassembly of the drum door ring 103 more convenient.
[0037] In one embodiment, an annular boss is provided on the drum door ring 103. A plurality of first relief grooves 1031 are formed on the annular boss and evenly divide the annular boss into a plurality of first limiting bosses 1032. When the first clamping boss is located in the first clamping groove 1011, as Figure 8 shown, a preset spacing is provided between the plurality of first limiting bosses 1032 and the plurality of first abutting units 1012, thereby forming a second clamping groove 1036. The second clamping boss 1051 can be clamped in the second clamping groove 1036 to achieve the sealing of the opening 1021 of the drum body 100.
[0038] In one embodiment, in order to separately implement the disassembly and installation of the cavity barrel door ring 103 and the opening and closing of the cavity barrel door 105, the first relief groove 1031 and the third relief groove 1013 are staggeredly distributed. In this embodiment, specifically, both the first relief groove 1031 and the third relief groove 1013 are arc-shaped structures, and the centers of the circles corresponding to the first relief groove 1031 and the third relief groove 1013 are both located on the central axis of the first clamping convex structure, that is, the projections on the plane where the cavity barrel door ring 103 rotates are at the same point. The midpoint positions of the arc-shaped first relief groove 1031 and the midpoint position of the arc-shaped second relief groove 1035 are not collinear with the connecting lines of their respective corresponding centers on the plane where the cavity barrel door ring 103 is located and form a certain angle, so that the first relief groove 1031 and the third relief groove 1035 are staggeredly distributed. When the first clamping unit 1034 corresponds to the position of the third relief groove 1013, the second clamping boss 1051 abuts against the first limiting boss 1032, so that the cavity barrel door ring 103 can be removed. When the position of the first relief groove 1031 corresponds to the position of the second clamping boss 1051, the first clamping unit 1034 and the first abutting unit 1012 abut against each other, so that only the disassembly or installation of the cavity barrel door 105 can be performed.
[0039] In one embodiment, it further includes a driving assembly for rotating the cavity barrel door ring 103. The driving assembly includes a driving member and a rotating member. The driving member is arranged on the mounting base 101. One end of the rotating member is connected to the output end of the driving member, and the other end of the rotating member is connected to the cavity barrel door ring 103. Specifically, in this embodiment, as a preferred embodiment, the driving member is the first motor 104. The rotating member includes a first driving gear 1041 arranged at the output end of the first motor 104 and a first arc-shaped rack 1033 arranged on the outer periphery of the cavity barrel door ring 103. The first driving gear 1041 meshes with the first arc-shaped rack 1033, and the first arc-shaped rack 1033 is coaxially arranged with the cavity barrel door ring 103. By the forward and reverse rotation of the first motor 104, the disassembly and installation of the cavity barrel door ring 103 and the cyclic opening and closing of the cavity barrel door 105 are realized. In this embodiment, when the first motor 104 rotates and drives the cavity barrel door ring 103 to rotate by 18 degrees, at this time, the second clamping boss 1051 corresponds to the position of the first relief groove 1031, and the cavity barrel door 105 can be opened and separated from the cavity barrel 100. When the first motor 104 continues to rotate and drives the cavity barrel door ring 103 to further rotate, when it continues to rotate by 25 degrees, at this time, the first clamping unit 1034 corresponds to the position of the third relief groove 1035, and the cavity barrel door ring 103 can be disassembled.
[0040] Further, in order to ensure the relatively precise relative position between the barrel door ring 103 and the mounting base 101, a position detection sensor is also included, which is arranged on the barrel door ring 103. When it detects that the barrel door ring 103 rotates through a first preset angle, i.e., the aforementioned 17° angle, the position of the first relief groove 1031 corresponds to that of the second clamping boss 1051. At this time, the first motor 104 stops rotating, and the barrel door 105 can be opened or closed. When the barrel door ring 103 rotates to a second preset angle, i.e., the aforementioned 25-degree angle, the first motor 104 stops rotating at this time. Compared with the first time, it increases by 7 degrees, and the position of the third relief groove 1013 corresponds to that of the first clamping unit 1034, and the barrel door ring 103 can be disassembled.
[0041] Optionally, the first driving gear 1041 can also be set as a straight rack meshing with the first arc rack 1033. By the reciprocating linear movement of the straight rack, the reciprocating rotation of the barrel door ring 103 is realized, so as to adjust the position of the first clamping unit 1034 on the barrel door ring 103 relative to the third relief groove 1013 and the position of the second clamping boss 1051 relative to the first relief groove 1031.
[0042] In one embodiment, a telescopic assembly is further included, which is arranged on one side of the opening 1021 of the barrel body 100. The free end of the telescopic assembly is connected to the barrel door 105. By the telescopic movement of the free end of the telescopic assembly along the axis where the barrel body 100 is located, the sealing of the barrel door 105 to the opening 1021 or the separation from the opening 1021 is realized. In this embodiment, the telescopic assembly can be a push rod cylinder, or a structure combining a motor and a screw rod slider with a limit guide rail.
[0043] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made. These improvements and refinements should also be regarded as the protection scope of the present invention.
