Description

Technical Field

[0001] The utility model relates to the technical field of cold storage doors, and more specifically to an explosion-proof electric translation cold storage door with sound insulation and noise reduction. Background Art

[0002] Cold storage door refers to the door installed in cold storage equipment, frozen warehouses and other freezing environment equipment for insulation and sealing. The cold storage door adopts high-strength aluminum alloy profile door frame, which has high strength, no deformation, beautiful appearance and durability.

[0003] Existing cold storage doors all have the ability to soundproof and reduce noise, but when storing items in some cold storages, some items may produce flammable gases or flammable substances under certain conditions, such as ammonia, ethanol, etc. If these gases or substances are not handled in time and accumulate to a certain extent, accidents such as fires and explosions may occur, posing a great threat to people and property.

[0004] Although the existing cold storage door has high strength, its explosion-proof ability is low and it cannot release the high-pressure gas generated in the cold storage in time. As a result, when the air pressure in the internal space of the cold storage increases without knowing it, an explosive airflow is likely to be generated when the cold storage door is opened, causing harm to the people entering and damage to the surrounding property and facilities. Therefore, an explosion-proof electric sliding cold storage door with sound insulation and noise reduction is proposed. Utility Model Content

[0007] The door body comprises an inner supporting layer and two outer layers, outer layers are installed on both sides of the inner supporting layer, the inner supporting layer and the two outer layers are connected to form two cavities, and the cavities are filled with polyurethane.

[0008] Preferably, the moving mechanism includes a motor, a screw and a slider, the motor output end is connected to the screw, two sliders are sleeved on the screw, both sides of each slider are slidably connected to the corresponding guide rail, and connecting parts are installed at the bottom ends of the two sliders.

[0013] Technical effects and advantages of the utility model:

[0014] 1. By installing an air pressure sensor and a pressure relief valve on the door body, compared with the prior art, the air pressure sensor can sense changes in the air pressure inside the cold storage. When the air pressure continues to increase and exceeds the set threshold, the pressure relief valve releases the pressure, thereby avoiding continuous increase in the air pressure in the cold storage, reducing the possibility of internal explosion, and improving the safety of cold storage storage;

[0015] 2. By filling the door body with polyurethane formed by the inner support layer and the outer layer, when the door body is subjected to shock waves, the hardened polyurethane of the protective plate is squeezed and the hardened polyurethane absorbs the shock wave energy. The first support plate guides the second support plate, so that the protective plate can be guided at multiple points so that the shock wave energy is evenly covered on the protective plate, thereby reducing the impact energy per unit area, thereby reducing the possibility of deformation and improving the explosion-proof effect.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] As attached Figure 1-6 The explosion-proof electric sliding cold storage door with sound insulation and noise reduction shown in the figure includes a fixed frame 1, a moving mechanism 2 is installed in the fixed frame 1, guide rails 3 are installed on both sides of the fixed frame 1, the moving mechanism 2 is slidably matched with the two guide rails 3, and two connecting parts 4 are connected to the bottom end of the moving mechanism 2, and the bottom ends of the two connecting parts 4 are connected to the door body 5, and an air pressure sensor 6 and a pressure relief valve 7 are installed on the door body 5, and the pressure relief valve 7 is arranged on the top of the air pressure sensor 6; the door body 5 includes an inner support layer 51 and two outer layers 52, and the outer layers 52 are installed on both sides of the inner support layer 51, and the inner support layer 51 and the two outer layers 52 are connected to form two cavities, and the cavities are filled with polyurethane.

[0025] During specific implementation, the door body 5 is moved by the moving mechanism 2 to realize the opening and closing of the cold storage. When the cold storage is closed, the air pressure sensor 6 can sense the change of the air pressure inside the cold storage. When the air pressure continues to increase and exceeds the set threshold, the pressure relief valve 7 releases the pressure, thereby avoiding the continuous increase of the air pressure in the cold storage and reducing the possibility of internal explosion. At the same time, when an explosion occurs inside the cold storage, the polyurethane filled between the inner support layer 51 and the outer layer 52 enables the door body 5 to have the ability of noise reduction and heat insulation. At the same time, when the generated shock wave rushes into the outer layer 52, the hardened polyurethane can absorb the shock wave energy, thereby improving the impact resistance of the door body 5 and thus improving the explosion-proof effect.

[0026] As attached Figure 4As shown, the moving mechanism 2 includes a motor 201, a screw rod 202 and a slider 203. The output end of the motor 201 is connected to the screw rod 202. Two sliders 203 are sleeved on the screw rod 202. Both sides of each slider 203 are slidably connected to the corresponding guide rail 3. Connectors 4 are installed at the bottom ends of the two sliders 203.

[0027] When the moving mechanism 2 is working, the motor 201 drives the screw rod 202 to rotate, so that the two sliders 203 move in the same direction along the guide rail 3, so that the door body 5 connected to the bottom end connecting piece 4 moves along. By changing the moving direction of the door body 5, the cold storage can be opened and closed.

[0028] As attached Figure 5 As shown, the inner support layer 51 includes an inner frame 5101, a partition 5102, and a first support plate 5103. A partition 5102 is arranged in the middle of the inner frame 5101, and empty grooves are arranged on both sides of the partition 5102. A plurality of first support plates 5103 are evenly welded in the empty grooves, and each of the first support plates 5103 is in an isosceles trapezoidal structure. An injection port is arranged at the bottom end of one side of the empty groove, and an overflow port is arranged at the top end of the other side of the empty groove. The injection port and the overflow port are both provided with sealing covers.

[0029] As attached Figure 3 and Figure 6 As shown, the outer layer 52 includes a protective plate 5201, a connecting frame 5202 and a second support plate 5203, a connecting frame 5202 connected to the inner frame 5101 is welded on one side of the protective plate 5201, and a plurality of second support plates 5203 are welded on the protective plate 5201 on the inner side of the connecting frame 5202, the second support plates 5203 have the same structure as the first support plates 5103, and each second support plate 5203 is inserted in the gap between two first support plates 5103.

[0030] After the door body 5 is formed by installing the outer layer 52 on both sides of the inner support layer 51, polyurethane is injected into each injection port so that the polyurethane fills the internal cavity and overflows from the overflow port after filling. The injection port and the overflow port are sealed by a sealing cover to harden the polyurethane in the cavity, so that the door body 5 forms an integral structure. When the door body 5 is subjected to a shock wave, the hardened polyurethane of the protective plate 5201 is squeezed and the hardened polyurethane absorbs the shock wave energy. The first support plate 5103 guides the second support plate 5203, so that the protective plate 5201 can be guided at multiple points so that the shock wave energy is evenly covered on the protective plate 5201, thereby reducing the impact energy per unit area, thereby reducing the possibility of deformation and improving the explosion-proof effect.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
