Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a liquid fire-retardant oil conveying device. Background Technology

[0002] Currently, phosphorus-based liquid flame retardants are widely used in the engineering plastics industry. Phosphorus-based liquid flame retardants can effectively inhibit combustion through multiple mechanisms of action, and produce fewer toxic and harmful gases during combustion, posing less harm to the environment and human health, thus aligning with the current trend of green and environmentally friendly development.

[0003] Traditionally, liquid fire-retardant oil is transported using a single preheating tank per production line. In multi-production-line scenarios, multiple preheating tanks are required, occupying significant space. Furthermore, the use of multiple preheating tanks increases equipment investment and maintenance costs, leads to higher energy consumption, and hinders improvements in production efficiency and the achievement of energy conservation and emission reduction goals.

[0004] Currently, there is a lack of a centralized liquid fire-retardant fuel delivery system that can be shared by multiple production lines. Utility Model Content

The bottom outlet of the stirring and heating tank is connected to the inlet of the gear pump through the second pipe. The outlet of the gear pump is connected to at least three branch pipes, and each branch pipe is equipped with a valve and a liquid metering scale.

[0010] This invention uses a single preheating tank to centrally feed materials to multiple branch pipelines.

[0011] More preferably, the heated sidewall includes an inner heating layer, a heat insulation layer, and an outer cover arranged sequentially from the inside to the outside;

[0012] The inner heating layer includes parallel heating bands arranged longitudinally.

[0013] The inner heating layer also includes three arc-shaped heat sinks, which are staggered with the heating band.

[0014] More preferably, at least two rollers are installed at the bottom of the heated sidewall.
