Description

Technical Field

[0001] The utility model belongs to the technical field of smoke equipment, and in particular relates to a dry ice releasing device. Background Art

[0002] Dry ice changes from solid to gas directly under atmospheric pressure without passing through liquid. This phenomenon is called sublimation. Spraying dry ice on the stage of a movie or TV show will rapidly sublimate and absorb heat to become a gas, condensing the surrounding water vapor into a smoky state. This is how people often use dry ice to create a smoky effect. In addition, since the specific gravity of carbon dioxide is 1.5 times that of air, it will flow down to the stage to form a low-lying smoky state. Therefore, dry ice is used on the stage in this way. If you use a large professional dry ice machine to put dry ice on it and spray it on the stage, it will feel like a spray. This is how the scene of a stage performance covered by smoky clouds is created.

[0003] Most of the dry ice smoke machines in the prior art achieve the effect of generating smoke by setting a dry ice drain basket, which is raised and lowered and immersed in hot water. However, this method has a disadvantage, that is, when the dry ice smoke machine needs to work for a long time, the amount of dry ice in the dry ice drain basket is limited. When the dry ice is added to the dry ice drain basket (the dry ice drain basket needs to rise and separate from the water), the smoke generation will be interrupted, affecting the continuous spraying of the dry ice smoke machine, which is not conducive to the continuous scene of the stage being shrouded in smoke.

[0004] Based on the deficiencies in the prior art, the utility model discloses a dry ice releasing device, which provides a dry ice crushing box and a feeding assembly for conveying dry ice into a hot water barrel at the lower end of the dry ice crushing box, so that the dry ice crushing box and the hot water barrel are independent of each other, so that dry ice can be conveniently replenished into the dry ice crushing box at any time, thereby ensuring the continuous spraying of the dry ice smoke machine.

By arranging a dry ice crushing box and arranging a feeding assembly for conveying dry ice into the hot water bucket at the lower end of the dry ice crushing box, the dry ice crushing box and the hot water bucket are independent of each other, so that dry ice can be conveniently added to the dry ice crushing box at any time, thereby ensuring the continuous spraying of the dry ice smoke machine.

[0030] A smoke outlet 8 is provided at the upper end of a side surface of the box body 1 away from the dry ice supply chamber 3 , and the smoke outlet 8 is connected to the upper end of the smoke generating chamber 4 . An exhaust fan 9 is also provided at the upper end of the smoke generating chamber 4 at the smoke outlet 8 .

[0031] Universal wheels are respectively arranged at the corners of the lower end surface of the box body 1 .

[0032] The inner wall of the dry ice supply chamber 3 is provided with a heat-insulating layer, which is convenient for storing dry ice.

[0035] The crushing box 51 is in a hollow cylindrical shape.

[0036] The crushing assembly includes a rotating shaft 54, which is coaxially arranged inside the crushing box 51. The upper end of the rotating shaft 54 ​​is connected to the upper end surface of the crushing box 51 through a bearing. The upper end surface of the crushing box 51 is also provided with a crushing motor 55 for rotating the rotating shaft, and a crushing knife group 56 is provided on the rotating shaft.

[0038] A plurality of crushing blade groups 56 are provided, and the plurality of crushing blade groups 56 are evenly arranged at equal intervals along the axis direction of the rotating shaft 54 ​​.

[0039] The operation of the crushing motor 55 can drive the rotation of the rotating shaft 54, thereby driving the crushing knife group 56 to rotate to crush the dry ice inside the crushing box. The crushed dry ice is transported from the discharge port 53 to the inside of the hot water barrel through the operation of the feeding auger. When the dry ice contacts the hot water in the hot water barrel, a large amount of smoke will be generated, and the smoke will be ejected from the smoke outlet 8 through the operation of the exhaust fan.
