This invention discloses a low-temperature carbon dioxide high-expansion foam dust suppression system and method for ore pass unloading. The dust suppression system includes a first high-expansion foam generator and a second high-expansion foam generator at the ore pass unloading port and ore bin, respectively. A foaming dust suppressant is mixed with inert carbon dioxide gas and a sulfide ore inhibitor to create foam with both dust suppression and ore spontaneous combustion inhibition properties. Because the foam contains an ore inhibitor, the spontaneous combustion tendency of ore dust upon contact with the foam is effectively reduced. Simultaneously, after the foam bursts, the low-temperature carbon dioxide gas within it lowers the ambient temperature and oxygen concentration within the ore pass, creating a low-temperature, low-oxygen environment and reducing the risk of ore spontaneous combustion and agglomeration within the ore pass. Furthermore, the low-temperature carbon dioxide generates natural convection, inducing airflow within the ore pass and accelerating foam diffusion. Therefore, this invention's low-temperature carbon dioxide high-expansion foam dust suppression system achieves synergistic prevention and control of dust and ore spontaneous combustion within the ore pass.

This utility model relates to a fire-resistant storage device for oily waste bleaching clay, comprising a storage tank connected to the discharge pipe of at least one filter, a spraying assembly for spraying atomized water onto the oily waste bleaching clay inside the storage tank, an inflation assembly for filling the storage tank with inert gas, a detection assembly for detecting the storage environment inside the storage tank, and a controller for controlling the spraying of atomized water and the filling of inert gas. This utility model uses the detection assembly to detect the temperature, smoke, and oxygen content inside the storage tank containing the oily waste bleaching clay. Based on the detection results, nitrogen is injected into the storage tank using the inflation assembly to reduce the oxygen content. The spraying assembly sprays atomized water onto the oily waste bleaching clay inside the storage tank. These two methods work together to reduce water consumption and also reduce the risk of spontaneous combustion of the oily waste bleaching clay, thus improving storage safety.

The utility model discloses a kind of transfer devices for spitting pearl type firework production, including transfer trolley and storage box, the storage box is fixed on transfer trolley, the upper side of the storage box is open, the support plate is slidably arranged in the inside of the storage box, and the side surface of support plate is in contact with the inside of storage box, the bottom of the storage box inner chamber is provided with the elastic support component for positioning support plate. The transfer device for spitting pearl type firework production, not only can buffer spitting pearl type firework to prevent it from stress dispersion during transfer process, but also can be used for the heat dissipation of spitting pearl type firework, avoid long time continuous jolt to cause firework pearl friction heat to occur spontaneous combustion, improve the security during transfer, while the transfer device can be used for the adjustment of firework taking and placing height, avoid the collision between fireworks due to the placement position is deeper during placement process to affect the firework pearl ignition effect, and convenient to take out firework from the transfer device.
