Integrated noise suppression apparatus for a pneumatic vacuum elevator

A pneumatic vacuum elevator (20) comprising:

• one or more vertically stacked elevator cylinders (50) configured to enable one or more users to move between a plurality of floors of a multi-storied building;
• an integrated noise suppression apparatus (10) integrated on top of the one or more elevator cylinders (50), wherein the integrated noise suppression apparatus (10) comprises:
• an equipment compartment (30) mounted on top of a cylinder of one or more vertically stacked elevator cylinders (50), wherein the equipment compartment comprises:
• a first partition unit (60) vertically surrounding one or more electric motors (70) housed inside the equipment compartment (30), wherein the one or more electric motors (70) are configured to suck air from one or more vertically stacked elevator cylinders (50) and release the air into atmosphere surrounding the equipment compartment (30) to operate the pneumatic vacuum elevator (20) in upward direction;
• a bottom plate (80) comprising a channel (85) positioned outside the first partition unit (60), wherein a pneumatic flow control unit (90) placed on top of the bottom plate (80), wherein the pneumatic flow control unit (90) is configured to allow air from the atmosphere into the corresponding one or more elevator cylinders (50) to operate the pneumatic vacuum elevator (20) in downward direction;
• a second partition unit (100) mechanically coupled to the first partition unit (60), wherein the second partition unit (100) comprises an opening (110) in a pre-defined shape, wherein the second partition unit (100) is configured to circulate air between the equipment compartment (30) and the atmosphere upon being sucked or released by the one or more electric motors (70) or the pneumatic flow control unit (90) respectively;
• a silencer unit (120) placed below the one or more electric motors (70) and the pneumatic flow control unit (90) and configured to absorb noise developed during operation of the pneumatic vacuum elevator (20) upon air being circulated sequentially from the first layer (130) to the fifth layer (170), wherein the silencer unit (120) comprises:
• a first layer (130) placed upon the bottom plate (80) and above a tubular cylinder (40), wherein the first layer (130) comprises a first set of partition strips arranged in a pre-defined fashion, wherein each of the first set of partition strips comprises a corresponding plurality of square cut-outs arranged in a first pre-defined fashion, wherein the first set of partition strips is configured to initiate the circulation of air;
• a second layer (140) placed above the first layer (130), wherein the second layer (140) comprises a second set of partition strips arranged in a pre-defined fashion, wherein each of the second set of partition strips comprises a corresponding plurality of square cut-outs arranged in a second pre-defined fashion;
• a third layer (150) placed above the second layer, wherein the third layer (150) comprises a third set of partition strips arranged in a third pre-defined fashion, wherein each of the third set of partition strips comprises a corresponding plurality of square cut-outs arranged in a third pre-defined fashion;
• a fourth layer (160) placed above the third layer (150), wherein the fourth layer (160) comprises a fourth set of partition strips arranged in a fourth pre-defined fashion, wherein each of the fourth set of partition strips comprises a corresponding plurality of square cut-outs arranged in a fourth pre-defined fashion;
• a fifth layer (170) placed above the fourth layer, wherein the fifth layer (170) comprises a fifth set of partition strips (180), wherein each of the fifth set of partition strips (180) comprises a corresponding plurality of circular cut-outs arranged in a fifth pre-defined fashion, wherein the plurality of circular cut-outs are structured to position the corresponding one or more electric motors (70), wherein a plurality of layers (190) is arranged one above the other to enable the air to pass between the atmosphere and the tubular cylinder (40) via the plurality of layers (190), and
• wherein an arrangement of the first set of partition strips, the second set of partition strips and the third set of partition strips forms a pre-defined structure configured to absorb noise developed during operation of the pneumatic vacuum elevator (20) upon air being circulated sequentially from the first layer (130) to the fifth layer (170).
