AI Technical Summary

Technical Problem

In existing vacuum slurry immersers, the photoelectric level sensor is easily affected by the viscosity of the slurry and the sensitivity decreases. The float level meter may explode due to the imbalance of internal and external pressures in a vacuum environment, so it is impossible to effectively monitor the slurry level.

Method used

A floating ball device including a hollow float ball and a hollow rod is adopted. The hollow float ball floats on the slurry surface, with the other end of the hollow rod facing upward. When the casing is closed and vacuumed, the air in the float device is drawn away to avoid explosions while maintaining a floating state to ensure sensitivity and stability of liquid level monitoring.

Benefits of technology

It effectively avoids the phenomenon of floating ball device explosion due to internal and external pressure imbalance, and maintains sensitive monitoring of the slurry surface height, ensuring the slurry quality of the wax mold in the slurry immersion machine.

Abstract

The present invention provides a vacuum pulping machine, including a base, a motor, a pulp tube, and a shell. The bottom of the pulp tube is provided with a downward vertical shaft, and a pulley is installed at the end of the vertical shaft after passing through the base downward. The pulley is connected to the motor output shaft through a belt. Under the drive of the motor, the pulp tube can rotate relative to the base. The shell covers the pulp tube from top to bottom and is sealed and fixed on the base. The shell is provided with a vacuum exhaust hole. The inside of the shell is provided with a tree assembly clamp and a tree assembly clamp lifting rod, as well as a float device that can be inserted into the pulp tube. The float device includes a hollow float and a hollow rod connected to the hollow float cavity. The hollow float always floats on the pulp surface in the pulp tube, and the opening at the other end of the hollow rod faces upward. Since the present invention adopts a float device with such a structure, it can sensitively and stably monitor and sense the height of the pulp surface in real time, thereby ensuring the pulping quality of the wax mold in the pulping machine.
