Air blower of tea drying equipment of internal composition of analysis
The working principle of the blower of tea drying equipment is that when the impeller rotates, due to the action of centrifugal force, the vane drives the gas to move forward outward, thus forming a series of spiral movements. The air between the impeller blades spirally accelerates and pushes the gas outside the pump body into the side slot (by suction).
When it enters the side channel, the gas is compressed and then returns to the impeller blades to accelerate the rotation again. When the air passes through the impeller and the side slot along a spiral path, each impeller blade increases the degree of compression and acceleration. As the rotation progresses, the kinetic energy of the gas increases, which further increases the pressure of the gas passing through the side channel. When the air arrives at the connection point between the side groove and the discharge flange (the side passage is narrowed at the exit), the gas is extruded from the blade and discharged from the pump body through the outlet muffler.
Tea drying equipment blower is widely used in the tea drying equipment, liquid filling machine, powder filling machine, food, packaging, filling, glass products, paper cutter, environmental protection water treatment, central dust environmental protection, automatic feeding machine, burning down YangJi, roll machine, filter machine, dust collection machine, environmental machinery, woodworking machinery, hot air machine, powder, granule machine, kitchen machinery machine, drying machine, incinerators, incubator, mechanical cooling, and other industries.
Air blower of tea drying equipment of the structural features
· The air blower is mainly composed of impeller, casing, air inlet, motor, connector, cooling blade and other components.
· The impeller is made of galvanized sheet or cold-rolled steel with multi-wing single inlet centrifugal impeller. The blade is designed according to aerodynamic principles. The impeller of the tea drying equipment blower is composed of 10 receding airfoil type blades, curved front plate and flat rear plate. Material with high strength, good durability of the steel plate manufacturing, and after strict dynamic and static balance correction, good air performance, high efficiency, smooth operation.
· The air inlet adopts the convergent streamlined vortex reduction form, with small airflow loss and high air blower efficiency.
· The air blower housing and the motor are installed and connected with metal castings. Cooling air blades are installed on the motor shaft head. High inlet and outlet water pipes are opened on the outer wall of the metal castings to cool down the metal castings and the shaft head to ensure the normal operation of the motor at high temperature.
· The motor adopts special high temperature motor, and the air blower fluid adopts temperature-resistant material, with reliable cooling structure performance. Compared with the boiler induced draft air blower, it has the advantages of simple structure, convenient maintenance and high cost performance.
Its internal mechanism is relatively tight, impeller and casing clearance is very small, so to filter debris and dust. For sundry, is generally installed in the air inlet on the fine mesh, dust, often used is a filter. According to the different use site, it often USES different filtration precision filter elements, different filter elements have different maintenance methods and service life, you need to ask clearly when ordering. In some special occasions, but also need to be special protection of tea drying equipment blower, such as in the sealed environment when using, to pay attention to ventilation heat; When the ambient temperature (intake temperature is relatively high), more attention should be paid to ventilation cooling, or choose to allow higher intake air temperature blower.z
