Description

Axial flow fan dryer Technical Field The utility model relates to the technical field of axial flow fans, in particular to an axial flow fan dryer. Background The axial flow fan has very wide application, namely, the air flow in the same direction with the axis of the fan blade, such as an electric fan, and the fan of the air conditioner external unit is an axial flow running fan. This is called "axial flow" because the gas flows parallel to the fan axis. Axial fans are commonly used in applications where flow requirements are high and pressure requirements are low. The axial flow fan fixes the position and moves the air. The axial flow fan mainly comprises an impeller and a shell, has a simple structure but has very high data requirements, when the impeller rotates, gas axially enters the impeller from an air inlet, is pushed by blades on the impeller to raise the energy of the gas, and then flows into a guide vane. The guide vane changes deflection airflow into axial flow, simultaneously guides gas into a diffuser pipe, further converts gas kinetic energy into pressure energy, and finally guides the gas into a working pipeline. The small axial fan has low power consumption, fast heat dissipation, energy conservation, environmental protection and the like. Because the volume is small, the application is wider, and the large axial flow fan has the characteristics of simple structure, stability, reliability, large air quantity, wide function selection range and the like, the axial flow fan needs to process the air duct during manufacturing. At present, the existing axial flow fan generally comprises a motor, an impeller and an air duct, and the working principle of the existing axial flow fan is that the motor is started, and the impeller is driven to rotate at a high speed through the motor, so that wind power is generated. In the scheme, the wall thickness of the traditional air duct is generally thinner, and the axial flow fan can generate repeated vibration during working, so that the air duct is easy to fatigue, and the service life of the air duct is lower. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide an axial flow fan air duct, which can improve the strength of the air duct by arranging a first reinforcing rib and a second reinforcing rib, solves the problem that the air duct is easy to fatigue due to repeated vibration in the prior art, and prolongs the service life of the air duct. The scheme for solving the technical problems is as follows: The utility model provides an axial fan dryer, includes the dryer that straight section of thick bamboo set up, and the both ends shaping of dryer has the turned-up edge, is fixed with first strengthening rib on the lateral wall of dryer, and the middle part of dryer is fixed with the second strengthening rib, and dryer internal fixation has the mounting bracket, and the upper end of mounting bracket is equipped with drive assembly, and drive assembly is located the middle part of dryer. Through being equipped with first strengthening rib to improved the bulk strength of dryer, drive assembly is at the during operation, and the vibration degree that the middle part of dryer received is most violent, through being equipped with the second strengthening rib, thereby improved the intensity at dryer middle part, thereby can effectually prevent the dryer because the problem of tired of repetitive vibration causes. Through being equipped with first strengthening rib and second strengthening rib to can improve the intensity of dryer, solved in the prior art wind section of thick bamboo and easily because the tired problem of vibration cause of repeatability, thereby improved the life of dryer. The utility model is further provided that the first reinforcing rib comprises three transverse ribs fixed on the outer side wall of the air duct, one transverse rib is positioned in the middle of the air duct, the other two transverse ribs are symmetrically arranged at two ends of the air duct, and the second reinforcing rib is positioned between the two symmetrically arranged transverse ribs. Through above-mentioned technical scheme, through being equipped with three horizontal muscle to can improve the bulk strength of dryer. The utility model is further provided that the second reinforcing ribs comprise a plurality of X-shaped ribs fixed on the outer side wall of the air duct, the middle part of each X-shaped rib is positioned in the middle part of the air duct, and the upper end and the lower end of each X-shaped rib are respectively and fixedly connected with the two transverse ribs. Through above-mentioned technical scheme, through being equipped with many "X" type muscle to the dryer intensity between two horizontal muscle that the symmetry set up has been improved, thereby can effectually prevent the dryer because the tired problem of vibration cause of repeatability, thereby improved the life of dryer.
