Problems solved by technology

In the actual assembly of shafts and holes with transmission threads, in order to achieve large load-bearing functions, the size of the threaded shafts and matching nut-like components are relatively large, and it is often easy and convenient to screw in during assembly, and It can realize the automatic and continuous locking of the bearing capacity during use, so it is very reliable, but when it is disassembled, the assembly is often very tight, and disassembly is very difficult. It is particularly important to realize simple and easy disassembly under this condition

Abstract

The invention discloses a hot air type penetration reverse flow fluidization drying machine with tail heat utilization and inertial dust collecting functions. The upper portion of a drying tower is connected with an induced draft fan. The induced draft fan is connected with an efficient cyclone dedusting tail heat recovery device in a tangential manner through an inertial dust collecting device and then performs evacuation, wherein the efficient cyclone dedusting tail heat recovery device is formed by overlaying a tube bank type heat exchanger and a cyclone dust collector. The air inlet end of a shell pass of the tube bank type heat exchanger is communicated with atmosphere, and the air outlet end is connected with the lower portion of the drying tower through an air blower and a steam fin heater; and blades of an impeller of the induced draft fan are arranged to be in a radiation shape and are in radial and central symmetry with respect to an impeller shaft, the dust can be cleared up in time through centrifugal force, and safety accidents are avoided. By the adoption of the hot air type penetration reverse flow fluidization drying machine, the drying efficiency is improved, and energy saving and emission reduction are achieved; and more importantly, the disassembly and assembly technology of the induced draft fan is improved greatly, so that pressure applied to the shaft shoulder end face of a screw by components similar to a nut component can be eliminated simply when the induced draft fan is disassembled, and the problem that the induced draft fan is locked continuously and automatically and cannot be disassembled easily under the load action due to threaded assembly is solved effectively; and the hot air type penetration reverse flow fluidization drying machine is especially suitable for convenient and fast disassembly of a large-scale fan which is locked in a threaded manner, and the effect is particularly obvious.

Description

technical field [0001] The invention relates to a drying machine, which specifically refers to a penetrating countercurrent fluidization drying machine which utilizes inertial dust-collecting hot air at the end of the fan without dust accumulation and is easy to disassemble and overhaul. Background technique [0002] Due to its mature technology, strong adaptability, low operating cost and strong reliability, the hot air dryer is still one of the main preferred equipment for drying materials. , and the effective recovery of tail heat is of special significance for improving drying efficiency and realizing energy saving and emission reduction. [0003] The induced draft fan is the key equipment of the hot air dryer. The induced draft fan is generally a centrifugal fan. The continuous, stable and reliable operation of the induced draft fan is very important for the dryer. Since most of the occasions where the dryer is used contain a certain amount of dust, the induced draft fa...
