The screw conveyor is 10 meters long and the conveying capacity is within 1000kg. The rated power of the basic screw conveyor motor is 1.5KW. The motor is driven by variable frequency speed reducer, and the transmission ratio is 1:20 ~ 1:80. The operating speed of this kind of screw conveyor with output power is about 3M ~ 15m, which is more applicable in the fields of food, drying and cleaning. The rated power of the screw conveyor motor is not fixed and consistent. It is related to the conveying speed and conveying capacity. Therefore, the hardware configuration of the output power is also an important main parameter. Increasing the rated power of the screw conveyor motor is a consumption in terms of cost. If it is reduced, the service life will be reduced or the motor will be very easy to burn.
The screw conveyor has such main parameters. According to the estimation, the conveying capacity per unit time of the screw conveyor can be obtained, and the output power can be calculated. The problem of whether the screw conveyor can reach the production capacity can be clarified according to the output power size. If the output power of the screw conveyor is inappropriate, the output power standard value can be changed according to the method of changing the total width and speed.
In the conveying work, the application of screw conveyor is indispensable. The model and specification of mesh belt equipped with screw conveyor depends on what level of conveying it is applied to. The screw conveyor for drying treatment uses eyelet single rotary mesh belt and adopts the structure of threaded rod transmission chain. The cleaning screw conveyor is equipped with double rotating herringbone or prismatic mesh belt. The former is used for heavy net and the latter is used for light weight. The screw conveyor of vacuum heat treatment furnace is equipped with non transmission chain mesh belt, and the barrel pushing structure is selected. Naturally, due to the different working natural environment, the mesh belt model and specification of the screw conveyor is not a certain one, which should be properly equipped according to the specific conveying conditions.
In the initial formulation, the conveying capacity of screw conveyor is also an important conveying main parameter. Only when the conventional working efficiency is achieved, can it be regarded as a normal machine and equipment. The conveying capacity of screw conveyor can not be generalized. The spacing of screw conveyor is different, and the relative density and conveying speed of raw materials are different, so the conveying capacity is also different. The normal operating speed of the screw conveyor is 0-20M (variable frequency and freely adjustable), and the thickness of the bearing raw materials is 100mm. According to this main parameter, it is then multiplied by the relative density of the transported raw materials to obtain the conveying capacity of the screw conveyor in unit time. Knowing the conveying capacity per unit time and comparing it with its ideal production capacity, we can make it clear whether the screw conveyor is feasible.
