Abstract
The utility model relates to a screw conveyer belonging to a material conveying device. The screw conveyer comprises a motor and a screw machine, wherein the motor is connected with the screw machine, the screw machine comprises a cylindrical casing, a feed port and a discharge port are arranged on the casing, a shaft is arranged in the casing, and a helical blade is installed on the shaft. The screw conveyer is characterized in that the shaft on which the helical blade is installed is a variable-diameter shaft, and the diameter of a shaft at the position of the feed port is greater than the diameter of a shaft at the position of the discharge port. Materials conveyed by the utility model are pushed out of the discharge port by the helical blade in a loose state, the friction force is very small, the utility model can work normally at low frequency, and the phenomenon of lathe blocking can not occur. The utility model has very obvious effect after being tested in Taihua group company for two months and can supply the materials normally and quantitatively at low frequency below 5Hz, equipment runs normally, and the problem of material supply, which constrains the gasification running of pulverized coal seriously, is thoroughly solved.
Description
Technical field:
The utility model belongs to device for transporting objects, is specifically related to a kind of conveyor screw.
Background technology:
At present, the conveyor screw that chemical enterprise uses is adjustable quantitative screw feeder, 10 times of fed distance are to screw diameter length, transport efficiency is very low, variable-frequency governor is when 10HZ is following, and vexed car phenomenon will take place adjustable quantitative screw machine, if expanded motor power, after the running short time vexed car phenomenon can take place also, causing can't ordinary production.
Summary of the invention:
The utility model aims to provide a kind of conveyor screw that vexed car phenomenon can not take place under the low frequency.
The realization the technical solution of the utility model is: comprise electrical motor, screw machine, electrical motor connecting bolt machine, screw machine comprises cylindrical shell, housing is provided with inlet point and discharging opening, be provided with axle in the housing, on the axle helicallobe be installed, it is characterized in that the axle that helicallobe is installed is multidiameter shaft, the diameter of the axle at inlet point place is greater than the diameter of discharging opening place axle, and the height of the helicallobe that the axle at inlet point place is upward installed is gone up the height of the helicallobe of installing less than the axle at discharging opening place.
The material that the utility model is carried is loosely released discharging opening like state by helicallobe with a kind of, and friction is very little, can be under low frequency normal operation, vexed car phenomenon can not take place.To have tested two months effects very obvious changing very much group company for the utility model, the normal dosing of low frequency that can be below 5HZ, and equipment operation is normal, has thoroughly solved the feed problem of serious restriction coal gasification operation.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1, frequency modulation motor, 2, the screw machine housing, 3, axle, 4, helicallobe, 5, inlet point, 6, discharging opening, 7, axle, 8, helicallobe.
The specific embodiment:
Embodiment: shown in Figure 1, present embodiment comprises frequency modulation motor 1, screw machine, frequency modulation motor 1 is by coupler connecting bolt machine, screw machine comprises cylindrical shell 2, and housing 2 is provided with inlet point 5 and discharging opening 6, is provided with axle 3 in the housing 2, axle 3 is a multidiameter shaft, on the axle 3 helicallobe 4 and helicallobe 8 are installed, the diameter of the part axle 7 at inlet point place is greater than the diameter of the axle at discharging opening place, and the depth of blade of the blade height ratio helicallobe 8 of helicallobe 4 is low.
