Automatic Powder Spray Explosion Suppression Device for Gas Pipelines
A gas pipeline automatic powder suppression and explosion-proof device is required for installation on gas pipelines where gas extraction and utilization are necessary. This device effectively addresses flames generated within the gas pipeline, providing protection against backfire, backflow, and explosions.

It operates with both electric and compressed-air drive options, offering high power output and robust mixing capabilities—resulting in fast stirring speeds and exceptional efficiency. This equipment can thoroughly blend one or more grouting (filling) materials, such as cement and fly ash, with water to create a uniformly mixed slurry, which is then ready for delivery to various mud pumps and grouting pumps for injection or filling tasks. When continuous, uninterrupted operation is required, it’s recommended to use two mixers: one dedicated to delivering the slurry, while the other handles the continuous feeding and mixing process.

The mine gel pump is a specially designed piece of equipment for mining operations. It’s a gel injection device capable of delivering high-water-content gels that are fire-retardant, heat-resistant, and formulated with precise proportions. Primarily used to convey high-temperature and high-water-content materials (water + gel material + accelerators), this pump automatically mixes water, gel material, and accelerators in specific ratios and delivers the mixture to the desired injection locations. Depending on the varying proportions of the ingredients, this liquid high-water gel mixture can solidify into a gel within 30 to 400 seconds. While in liquid form, it thoroughly penetrates the coal seam; during gelation, it absorbs heat; and once solidified, it encapsulates the coal mass and forms a stable buildup. As a result, this technology fully leverages its effectiveness in firefighting, enabling rapid and efficient control and extinguishing of fires.

Three-phase Foam Generation Device KSP900 for Coal Mines
The three-phase foam generation device for coal mines consists of a foaming system and a foaming agent injection pump. It leverages the mine’s existing grouting system—whether on the surface or underground—to inject the foaming agent, thereby reducing the surface tension of water and altering the physicochemical properties of fly ash and yellow mud surfaces. This process effectively achieves rapid fire prevention and extinguishing. The device ensures complete coverage of floating coal, both at low and high elevations, eliminating the common issue of uneven coverage during grouting that often leads to "grout leakage" and "channeling." By isolating oxygen from coming into contact with the coal, it halts the oxidation process and stops the exothermic reactions responsible for heat buildup.
