6. The multiple reinforced multiple flow guide mixing barrel structure for the hot mixer according to claim 5, wherein: a plurality of air inlet quick connectors are fixedly arranged at the top end of the shell, air inlets of the air inlet quick connectors are connected with an air source with pressure, and air outlets of the air inlet quick connectors extend into an inner cavity of the shell through corresponding top through holes in the top surface of the shell; when the valve core is in a state of opening the side discharging port, the air outlet of each air inlet quick connector is respectively used for blowing the surface of the valve core, the surface of the extending rod of the air cylinder, the surface of each guide rod and the inner cavity wall of the shell.
7. The multiple reinforced multiple diversion mixing barrel structure for a hot mixer according to claim 4, 5 or 6, wherein: the top surface of the shell is provided with an access hole communicated with the inner cavity of the shell, a sealing gasket is arranged at the access hole, the left end of the cover plate is hinged to the top surface of the shell at the left end of the access hole, and the cover plate rotates around the hinge point of the cover plate and the top surface of the shell to cover the access hole and is sealed and covered at the access hole through the sealing gasket and a fastener.
8. The multiple reinforced multiple flow guide mixing barrel structure for a hot mixer according to claim 7, wherein: the left side surface of the shell is also provided with a baffle plate, the top end of the baffle plate is higher than the top end of the shell, and when the cover plate rotates around a hinge point of the cover plate and the top end of the shell to abut against the baffle plate, the cover plate is supported by the baffle plate, so that the cover plate is maintained at the position.
9. The multiple reinforced multiple diversion mixing barrel structure for a hot mixer according to claim 4, 5 or 6, wherein: at least one inner cavity wall on the left inner cavity wall of the shell is outwards punched to form a first horizontal long-strip-shaped bulge which protrudes outwards, and at least one inner cavity wall on the right inner cavity wall of the shell is outwards punched to form a second horizontal long-strip-shaped bulge which protrudes outwards.
10. The multiple reinforced multiple diversion mixing barrel structure for a hot mixer according to claim 4, 5 or 6, wherein: the taper alpha 1 of the conical surface of the valve core is 10-15 degrees; the included angle alpha 2 between the axis of the discharging pipe and the horizontal plane is 45-60 degrees.
