ZHJ-167-1.8 Series Mine-Ready Fireproof Grouting Device
The mine-used fire-prevention grouting device is designed based on extensive field experience in coal mines, tailored to the economic and operational conditions of coal mining. It is a simple, practical, and reliable colloid-based fire-suppression system. This equipment can be integrated with ground-level fire-fighting systems, allowing firefighters to add coagulants or gel-forming agents—essential fire-extinguishing materials—directly into the grouting pipelines near underground injection points. Alternatively, it can also be used independently to inject high-molecular-weight colloids directly into active fire zones underground, effectively suppressing fires.

Mining fire-protection grouting device
Product Overview
The mine-used fire-prevention grouting device is designed based on extensive fire-fighting experience gained from coal mine sites, tailored to meet the economic and operational conditions of coal mines. It’s a simple, practical, and reliable colloid-based fire-suppression system. This equipment can be integrated with ground-level fire-extinguishing systems, allowing firefighters to add coagulants or gel-forming agents directly into the grouting pipelines near the point of application underground. Alternatively, it can also be used independently to inject high-polymer colloids directly into active fire zones underground, effectively helping to extinguish fires.
Product Features and Benefits
Features:
1. The equipment ensures stable flow and pressure, with accurate and uniform proportional mixing of fire-extinguishing materials. Additionally, the gelation speed of both the gel and composite colloid can be adjusted according to different conditions, optimizing the fire-prevention and extinguishing performance.
2. The equipment features a compact design, stable performance, and reliable operation; it is easy to operate and convenient to use and maintain.
Advantages:
1. The device is equipped with 2 funnel openings, allowing simultaneous mixing and injection of two types of powdered materials for grouting.
2. The equipment is relatively compact in size.
Terms of Use:
The loess and lime powder used should be screened and filtered to ensure they are free of particles and impurities.
Product Applications
This equipment is a complementary component of the colloidal fire-suppression system. When it’s necessary to inject gel or composite colloids into mine fire zones for fire prevention and extinguishing, this device can be used underground near the grouting points to add coagulants (such as NaHCO₃ or NH₄HCO₃) or gelling agents (model: FCJ12—this material is developed by our company and is exclusively manufactured by us) directly into the grouting pipelines.
