Steam smashing auxiliary feeding device on steam smashing machine

The invention provides a steam smashing auxiliary feeding device on a steam smashing machine. The steam smashing auxiliary feeding device comprises a pipe base and a metering pump, wherein the outlet pipe section of a liquid output pipe of the metering pump is inserted and connected to the pipe base, the pipe base is fixed on the pipe wall of a feeding inclined pipe in front of a feeding nozzle of the steam smashing machine, and the pipe base is provided with a channel penetrating the pipe wall of the feeding inclined pipe. A steam smashing auxiliary feeding point is arranged on the pipe wall of the feeding inclined pipe in front of the feeding nozzle of the steam smashing machine, the steam smashing auxiliary is sucked into a smashing region of the steam smashing machine by negative pressure formed by feeding steam, and the steam smashing auxiliary is fully mixed in a material grinding process. As the steam smashing auxiliary feeding point is in a micro negative pressure state, the outlet pipe section of the liquid output pipe of the metering pump can be connected to the pipe base by adopting an inserting manner; and during production monitoring and determination of addition amount of the steam smashing auxiliary, only the liquid output pipe of the metering pump is required to be pulled out, so that the determination of addition amount and production monitoring can be facilitated, terminal monitoring is realized, the addition amount is timely and effectively regulated, and the feeding effect of the steam smashing auxiliary is improved.
