Tail heat utilizes inertial dust removal sieve hole flap dryer

Abstract

The invention discloses a tail heat utilization inertial dust collection screen hole plate turnover type drying machine. A drying machine box body is provided with a screen hole plate turnover type conveying part from top to bottom and is provided with a middle partition plate and a lower partition plate, and the drying machine box body is divided into an upper drying area, a middle drying area and a lower drying area through the middle partition plate and the lower partition plate; the upper drying area is connected with an induced draft fan through an inertial dust collection device and an air heat exchanger to be subject to venting, the air outlet end is connected with an air blower air inlet, and an air blower air outlet is connected with a steam fin heater in the middle drying area; blades of an induced draft fan impeller are arranged to be in a radiation shape in impeller shaft radial and central symmetry, centrifugal force can be used for cleaning up dust in time, and safety accidents are avoided; and according to the drying machine, the drying efficiency is improved, energy saving and emission reduction are achieved, more importantly, the dismounting and mounting technology of the induced draft fan is greatly changed, and therefore during dismounting, the pressure of similar nut components on the end face of a screw shaft shoulder can be simply eliminated; and the problem that according to the induced draft fan thread assembly, automatic locking is continuously carried out under the load effect, and dismounting is not likely to be achieved is effectively solved, and the drying machine is particularly suitable for portable dismounting of a large-scale fan obtained after thread locking, and the effect is particularly obvious.

Description

technical field [0001] The invention relates to a drying machine, specifically referring to a flap type drying machine with tail heat utilizing inertial dust removal screen hole which does not accumulate dust in the fan and is easy to disassemble and overhaul. Background technique [0002] Due to its mature technology, strong adaptability, low operating cost and high reliability, hot air dryer has become one of the first choice equipment for material drying. The sieve flap dryer is a kind of hot air dryer, which has the characteristics of simple structure and strong processing capacity, and the quality of the dried product is particularly uniform and reliable because the material is turned over layer by layer during operation. During the drying process, the sieve flap dryer needs to continuously discharge hot and humid tail gas to promote the drying process. Since the exhaust gas is rich in a large amount of tail heat, it is necessary to perform tail heat utilization operati...

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
