Tail heat utilized hot-air type penetration countercurrent fluidized drying machine

TLDR: In this article, a tail heat utilized hot-air type penetration countercurrent fluidized drying machine is used to improve the drying efficiency of a large-scale draught fan. But, the problem that the fan is continuously automatically locked and is not easy to disassemble under the action of load in threaded assembling can be effectively solved.

Abstract: The invention discloses a tail heat utilized hot-air type penetration countercurrent fluidized drying machine A draught fan is connected to the upper part of a drying tower; the draught fan is tangentially connected with a cyclone dust removal tail heat efficient recoverer which is formed by a tube type heat exchanger and a cyclone dust collector which are overlapped, and is evacuated; the shell pass air inlet end of the tube type heat exchanger is communicated with the atmosphere; the air outlet of the tube type heat exchanger is connected to the lower part of the drying tower through an air blower and a steam fin heater; blades of the draught fan impeller are arranged in a radiation manner that impeller shafts are in radial and central symmetry; dust can be collected by virtue of centrifugal force in time, and thus security accidents can be avoided By adopting the tail heat utilized hot-air type penetration countercurrent fluidized drying machine, the drying efficiency is improved, the purposes of energy conservation and emission reduction are achieved, more importantly, the assembling and disassembling technique of the draught fan is greatly improved, pressure caused by components such as a screw nut to the shoulder end surface of a screw shaft can be easily eliminated when the draught fan is assembled and disassembled, the problem that the draught fan is continuously automatically locked and is not easy to disassemble under the action of load in threaded assembling can be effectively solved, and the tail heat utilized hot-air type penetration countercurrent fluidized drying machine is particularly applicable to convenient and rapid disassembling after a large-size draught fan is in threaded locking and is particularly remarkable in effect
