Abstract
Description
A wax melting device Technical Field
[0001] This utility model relates to the field of composite wax production equipment, specifically to a wax melting device. Background Technology
[0002] Currently, composite wax, as a raw material for emulsion explosives, requires liquefying large blocks of solid wax raw material, mixing it with other substances, reacting it, and then solidifying it into small granules for packaging, storage, and transportation. Currently, melting is mostly done in wax melting pools, which proceed slowly from the outside in, resulting in low efficiency. A pool of wax raw material requires a considerable amount of time to completely melt. After melting, the outlet of the wax melting pool needs to be opened to remove the molten wax raw material, leading to poor production continuity and making it unsuitable for the continuous production needs of engineering projects.

The heat-conducting medium flows into the medium flow cavity at one end of the heat-conducting stirring shaft, passes through the heat-conducting spiral blade, and then flows out from the medium flow cavity at the other end of the heat-conducting stirring shaft.
[0009] Multiple sets of crushing teeth are provided on the inner wall of the crushing shell.
[0010] A transverse crushing rod is provided on the spiral blades of the crushing spiral blade.

The heat-conducting stirring shaft 1 located inside the crushing shell 2 is provided with crushing spiral blades 6, and the heat-conducting stirring shaft 1 located inside the wax melting shell 3 is provided with heat-conducting spiral blades 7. The heat-conducting stirring shaft 1 is driven to rotate by a motor.
[0027] The heat-conducting stirring shaft 1 is mounted on the wax melting machine frame via bearings and bearing housings.
[0028] The heat-conducting stirring shaft 1 has media flow chambers 8 at both ends, and rotary joints 9 connected to the media flow chambers 8 are provided at both ends of the heat-conducting stirring shaft 1.
[0029] The heat-conducting spiral blade 7 is a hollow spiral blade. The heat-conducting spiral blade 7 is connected to the medium flow cavity 8. The heat-conducting medium flows into the medium flow cavity 8 at one end of the heat-conducting stirring shaft 1, passes through the heat-conducting spiral blade 7, and then flows out from the medium flow cavity 8 at the other end of the heat-conducting stirring shaft 1.
[0030] Multiple sets of crushing teeth 12 are provided on the inner wall of the crushing shell 2.
[0031] A transverse crushing rod 10 is provided on the spiral blade of the crushing spiral blade 6.
