Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of new energy aluminum foil clean workshops, and specifically designs a smoke barrier vertical wall for new energy aluminum foil clean workshops. Background Art
[0002] In the non-ferrous processing field, the new energy electronic aluminum foil precision cutting section and packaging area are usually clean workshops, with a general net height of less than 9m, mostly around 6m, and multiple smoke-proof partitions, and there is often a need to set up mechanical smoke exhaust. According to the relevant requirements of the current national standard "Technical Marking of Building Smoke and Exhaust Systems" (GB51251-2017), in areas with a clear space of less than 9m, smoke barriers need to be set up between multiple smoke-proof partitions. Since the smoke exhaust volume of a single smoke exhaust port is related to the height of the smoke barrier wall, the higher the wall, the greater the smoke exhaust volume of a single smoke exhaust port. When the total smoke exhaust volume of each smoke-proof partition is constant, the fewer the number of smoke exhaust ports, the more conducive to the arrangement of smoke exhaust ports and the reduction of investment. Under normal circumstances, in order to take into account the clear space occupied by the smoke barrier wall and the number of smoke exhaust ports, a fixed smoke barrier wall with a height of 1m is usually set. But this will bring another problem: the net height of the clean area is increased by 1m. Since the air supply volume of the clean air conditioning system in the clean area is related to the volume of the clean area, and the ventilation frequency is generally above 15 times / h, the clean area clearance is increased simply by adding a smoke barrier wall, and then the air supply volume of the clean air conditioning system is increased, resulting in an increase in the corresponding clean air conditioning energy consumption. Therefore, it is necessary to improve the above problem. Utility Model Content

[0004] In order to achieve the purpose of the utility model, the utility model adopts the following technical scheme: a new energy aluminum foil clean room smoke barrier wall, including a smoke barrier wall and an electronic lock, the smoke barrier wall is hingedly connected to the lower part of the clean room ceiling, and the electronic lock is fixedly arranged on the lower part of the clean room ceiling; when there is no fire, the smoke barrier wall is locked by the electronic lock, and the smoke barrier wall is parallel to the clean room ceiling, thereby reducing the clearance occupied by the smoke barrier wall, and reducing the design total clearance height of the clean room, thereby effectively reducing the design total clearance height of the clean room while meeting the clean room design standards, and reducing the power consumption of the clean air conditioning system; when a fire occurs, the electronic lock receives a signal from the fire control unit to release the lock of the smoke barrier wall, and the smoke barrier wall rotates and falls around the hinge axis by gravity, and is vertical to the clean room ceiling, playing the role of the smoke barrier wall and preventing smoke from spreading along the clean room ceiling.

[0006] Furthermore, a smoke barrier wall hinge seat is fixedly provided on the outer end surface of one side of the smoke barrier wall frame; a ceiling hinge seat is fixedly provided on the lower part of the clean room ceiling; the smoke barrier wall hinge seat and the ceiling hinge seat are hingedly connected through a hinge shaft.
[0007] Furthermore, an elastic glass pressure strip is provided between the glass and the frame retaining edge and the glass fixing frame to prevent the glass from being broken due to uneven force exerted by the frame retaining edge and the glass fixing frame on the glass.
[0008] Furthermore, sealing skirts are fixedly arranged on both side edges of the smoke barrier wall adjacent to the smoke barrier wall hinged seat. The sealing skirts are fixedly clamped between the smoke barrier wall frame and the glass fixed frame. Skirt sealing magnetic strips are arranged on both side surfaces of the sealing skirt near the outer end.
[0009] Furthermore, the smoke barrier walls and electronic locks are arranged in several columns, and each column of the smoke barrier walls and electronic locks is provided with several sets; the sealing skirts of adjacent smoke barrier walls overlap with each other, and are connected to each other through the magnetic force between the skirt sealing magnetic strips of the sealing skirts, so that the smoke barrier walls in the same column form an integral structure, thereby better exerting the function of the smoke barrier walls.

When the electromagnetic coil of the electronic lock is energized, the electromagnetic coil generates magnetic force, attracting the lock tongue to overcome the force of the return spring and move toward the inside of the electronic lock housing, thereby releasing the lock of the electronic lock on the smoke barrier wall. The smoke barrier wall rotates and falls around the hinge axis under the action of its own gravity, and finally is vertical to the clean room ceiling, playing the role of the smoke barrier wall.
[0011] Furthermore, the smoke barrier wall frame, glass fixing frame, smoke barrier wall hinge seat, ceiling hinge seat and hinge shaft are all made of stainless steel to prevent the above-mentioned structural parts from rusting and causing foreign objects to fall off, thereby polluting the environment of the clean workshop; the sealing skirt is made of flexible fireproof PVC sheet, and when the electromagnet releases the lock on the smoke barrier wall and releases a row of smoke barrier walls to rotate and fall, the flexible fireproof PVC sheet reduces the mutual collision of adjacent smoke barrier walls, thereby preventing the glass from breaking due to the mutual collision of the smoke barrier walls.
[0012] Furthermore, a proximity switch is fixedly provided on the electronic lock, and the proximity switch is used to detect whether the smoke barrier wall is in a parallel state with the clean room ceiling under normal conditions.
[0013] Furthermore, the electronic lock and the proximity switch are electrically connected to the clean room fire control unit; when a fire occurs, the clean room fire control unit controls the operation of the electronic lock; under normal conditions, the clean room fire control unit collects the proximity switch signal to detect whether the smoke barrier wall is in a parallel state with the clean room ceiling.
[0014] Due to the adoption of the technical scheme as described above, the utility model has the following beneficial effects: the utility model discloses a new energy aluminum foil clean room smoke barrier wall, which is hingedly arranged at the lower part of the clean room ceiling, and an electronic lock is fixedly arranged at the lower part of the clean room ceiling corresponding to the smoke barrier wall; under normal circumstances, the smoke barrier wall is locked by the electronic lock, so that the smoke barrier wall and the clean room ceiling are parallel, the clearance occupied by the smoke barrier wall is reduced, and the design total clearance height of the clean room is reduced; when a fire occurs, the electronic lock receives a signal from the fire control unit to release the lock of the smoke barrier wall, and the smoke barrier wall rotates and falls around the hinge axis by gravity, and is vertical to the clean room ceiling, playing the role of the smoke barrier wall to prevent smoke from spreading along the clean room ceiling; the new energy aluminum foil clean room smoke barrier wall effectively reduces the design total net height of the clean room on the premise of meeting the clean room design standards, and at the same time reduces the power of the clean air-conditioning system, thereby reducing the clean room investment and operating energy consumption of the new energy aluminum foil manufacturer.
