And sequentially pass through sealing ring, heater pedestal, plasma boiler for tube cell output terminal nozzle.
It is described for tube cell include seal assembly, for powder outer tube, for powder inner tube, two-tube connection cover, wherein for powder outer tube, for powder
Inner tube is loaded on for powder outer tube sleeve for powder inner tube outside to be co-axially mounted, for powder inner tube tail end with passing through for powder outer tube both ends side wall
Two-tube connection cover is weldingly connected and seals to be formed for powder wall, and seal assembly is installed to supplying powder outer tube and confession for powder outer tube head end
Powder inner tube input terminal is sealed.
The seal assembly is the column sealed material of hollow structure, and both ends side wall sets water inlet, water outlet to be used for respectively
Cooling water circulates.
The heater pedestal is stainless steel material.
The sealing ring material is polytetrafluoroethylene (PTFE), and thickness is not less than 10mm.
It is described to be installed for powder outer tube tail end with plasma boiler for small―gap suture cooperation.
The outer tube thickness of confession powder is 0.5mm~2mm.
It is described to be not more than 1mm for powder space layer.
Preferably, the cooling water pressure is not less than 1Mpa.
The advantages of the present invention over the prior art are that：
(1) a kind of induction plasma heating nodularization provided by the invention realizes outer tube, wall, inner tube for component powder
The effective cooperation and connection of three layers of thin-walled tubular structure, shellring nested structure is effectively formed circulating cooling aquaporin, to supplying tube cell
It is fully cooled, high temperature plasma flame inside can be deep into for tube cell by, which ensureing, carries out for a long time continuously for powder without quilt
Scaling loss.
(2) present invention uses the cyclic annular insulated enclosure circle of polytetrafluoroethylene material, and clamp nut squeezes it can be right
Fastening effect is played, therefore easy to adjust for elongation under tube cell for tube cell, convenient for meeting different target powder to the stroke that is heated
Requirement；While sealing function can be played, atmosphere is pure in guarantee heater；Material can play the role of insulation, protect
Insulation between testimony tube cell and pedestal, clamp nut and induction plasma body heater prevents from leading with plasma flame generation
Electric pathway.It can be seen that the design can play multiple action and it is simple in structure, adjust and replace convenient and efficient.
