Problems solved by technology

[0004] First, it is necessary to heat the delivery channel (screw conveyor) of the powder (titanium powder, zirconium powder or single base powder or other elemental or alloy flammable powder), and then heat the powder in the delivery channel to the ignition temperature, which consumes a lot of energy In particular, high ineffective energy consumption results in a waste of resources;
[0005] Second, the transportation of powder includes two screw conveyors, which need to be matched with two (sets) of drive or transmission mechanisms, resulting in a large working unit with a complex structure, which increases the equipment cost and reduces the reliability of the equipment; at the same time It also makes it difficult for the device to realize the parallel integration of multiple working units, and one device cannot realize the eruption of multiple light colors, and the color is monotonous

Embodiment 1

[0019] Embodiment 1: see attached figure 1 , reflecting a specific structure of the present invention, the powder combustion eruption device for imitating luminescent firework effects includes a casing 101, a power supply 107, a wireless control module 112, etc., and also includes a lower hopper 104 for loading powder through a filling port 118, the lower The hopper 104 is provided with a tubular feeding port 105, and the inner cavity of the tubular feeding port 105 is provided with a screw feeding rod 103, and the screw feeding rod 103 is connected with a speed regulating motor 119 as a rotation driving mechanism. The feeding rate of the screw conveying rod 103 can be controlled by controlling the speed and working time of the speed-regulating motor, so as to realize uniform metering and feeding. The screw feeding rod 103 is provided with three sets of agitating elements 117 whose radial dimensions gradually decrease on the rod body outside the tubular feeding opening 105 . ...

Embodiment 2

[0024] Embodiment 2: see attached figure 2 , 3 , including a multifunctional wiring device 18 , a wireless control module 19 and a power supply 20 installed in the housing 21 . In order to realize the eruption of multiple light colors, three lower hoppers 11 arranged side by side are included in this example, and each lower hopper 11 is loaded with powders of different flame colors through the filling port 9 . A screw feeding rod driven by a motor 10 and an agitator 12 are installed in the lower hopper 11 , and the motor 10 is provided with a cooling port 8 facing outside the casing 21 .

[0025] The bottom of each lower hopper 11 is correspondingly provided with a powder-gas mixing chamber 17 and its insulation layer 5, and the A ends of each powder-gas mixing chamber 17 are respectively connected to the four-way tap 13 of the intake pipe 22 through the electromagnetic valve 15, and the intake pipe 22 is provided with Insulation layer 14, special feeding fan 16 is connecte...

Abstract

The invention discloses a powder combustion and eruption device simulating the effect of cold light fireworks. The powder combustion and eruption device comprises a blanking hopper loading powder, andthe lower part of the blanking port of the blanking hopper is connected with a powder and gas mixing chamber. The A end of the powder and gas mixing chamber communicates with an air inlet pipe through an electromagnetic valve, the B end of the powder and gas mixing chamber communicates with an eruption pipe and is also provided with an electronic ignition mechanism. The air inlet pipe is connected with a fan and is provided with an air heating mechanism, and the fan also communicates with the eruption pipe. The device heats the powder by a mode of mixing high-pressure high-temperature air andpowder and conveys the powder at the same time. The device has the advantages of energy saving, high efficiency, reliable work, simple and light equipment and low cost. Meanwhile, one device can integrate and realize the eruption of multi-color fireworks, and the means of expression is enriched.

Description

technical field [0001] The invention relates to a powder combustion eruption device, which constitutes an eruption effect imitating luminescent fireworks. Background technique [0002] Chinese patent documents CN 105241316 A, CN 105258576 A, CN 105371707 A, CN 105854317A, CN 107121022 A etc. disclose a cold pyrotechnic eruption device. It is intended to replace the traditional gunpowder-launched luminescent pyrotechnics, and no longer needs gunpowder to eliminate potential safety hazards. [0003] But, existing equipment still has following disadvantages: [0004] First, it is necessary to heat the delivery channel (screw conveyor) of the powder (titanium powder, zirconium powder or single base powder or other elemental or alloy flammable powder), and then heat the powder in the delivery channel to the ignition temperature, which consumes a lot of energy In particular, high ineffective energy consumption results in a waste of resources; [0005] Second, the transportation...
