Abstract

A principal ventilator whose inner and outside tubes support mutually solves the technical problems of: torsional vibration caused by repeated fluctuating load of motor which is caused by the uneven gas-flow resistance within the flow passage. The utility model is characterized in that: the central lines of the inner and outer tubes are overlapped, 2 circles of supporting ventilation pipes are fixedly connected between the inner and the outer tubes with each circle of supporting ventilation pipe provided with 4 ventilation pipes, the extension line the 2 ventilation pipes above which cross the axial central line of the inner and outer tubes subtend the vertical central line of the inner and outer tubes at an angle of 90 degrees, the extension line of axial leads of the two ventilation pipes which are arranged symmetrically along the vertical central line of the inner and outer tubes at the lower part meet above the axial central line of the inner and outer tubes. The utility model can even the gas flow resistance within the flow passage of the ventilator, prevent torsional vibration caused by repeated fluctuating load of motor which is caused by the uneven gas-flow resistance within the flow passage, therefore, is suitable to be applied in ventilation system of mines.

Description

The main fan that inner/outer tube supports mutually
Technical field
The utility model relates to a kind of main ventilation system that is used for mine ventilation system.
Background technique
The air duct of common main fan at present, is not seen ready-made solution as yet because motor is subjected to turning round shake owing to the inhomogeneous alternate load that causes of gas-flow resistance in the runner causes.
Summary of the invention
The purpose of this utility model provides the main fan that a kind of interior inhomogeneous alternate load that causes of gas-flow resistance of runner that can solve air duct preferably because motor is subjected to causes that the inner/outer tube of turning round shake supports mutually.
The technological scheme that its technical problem that solves the utility model adopts is: the bottom of urceolus 3 is fixed with bearing, the central suit inner core 1 of urceolus 3, and the central lines of urceolus 3 and inner core 1, motor is installed in the inner core 1, binding tube 4 passes the barrel of inner core 1 and urceolus 3 respectively and connects firmly with the barrel of inner core 1 and urceolus 3 respectively, between urceolus 3 and inner core 1, cooperate and be fixedly connected with 2 circles and support ventilation ducts, every circle supports the ventilation duct 2 that ventilation duct is separately installed with 4, the shaft axis elongation line of 2 ventilation ducts 2 on top by urceolus 3 and inner core 1 longitudinal center line and be symmetrically 90 degree with respect to the vertical center line of urceolus 3 and inner core 1 and distribute, the shaft axis elongation line that is symmetrically 2 ventilation ducts 2 in bottom of distribution with respect to the vertical center line of urceolus 3 and inner core 1 crosses directly over the longitudinal center line of urceolus 3 and inner core 1.The distance of the longitudinal center line of joint and urceolus 3 or inner core 1 is less than the internal diameter of inner core 1 directly over the longitudinal center line of the shaft axis elongation line of 2 ventilation ducts 2 in bottom and urceolus 3 or inner core 1.
The beneficial effects of the utility model are: arrange 4 ventilation ducts on the single cross section, each 2 of upper and lower parts can make the interior gas-flow resistance of blower fan runner even, avoid motor to be subjected to owing to the inhomogeneous alternate load that causes of gas-flow resistance in the runner.Ventilation duct is a supporting element, is again the passage of motor radiating air-flow simultaneously.Inner core can be avoided owing to rotated by impeller and the air-flow effect causes turns round shake in lower half portion ventilation duct center line intersection point skew center of circle.It can be widely used in the ventilation system in mine.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical profile structural representation of Fig. 1.
Among the figure: 1-inner core, 2-ventilation duct, 3-urceolus, 4-binding tube.
Embodiment
Embodiment 1, the bottom of urceolus 3 of the present utility model is fixed with bearing, the central suit inner core 1 of urceolus 3, and the central lines of urceolus 3 and inner core 1, motor is installed in the inner core 1, binding tube 4 passes the barrel of inner core 1 and urceolus 3 respectively and connects firmly with the barrel of inner core 1 and urceolus 3 respectively, between urceolus 3 and inner core 1, cooperate and be fixedly connected with 2 circles and support ventilation ducts, every circle supports the ventilation duct 2 that ventilation duct is separately installed with 4, the shaft axis elongation line of 2 ventilation ducts 2 on top by urceolus 3 and inner core 1 longitudinal center line and be symmetrically 90 degree with respect to the vertical center line of urceolus 3 and inner core 1 and distribute, the shaft axis elongation line that is symmetrically 2 ventilation ducts 2 in bottom of distribution with respect to the vertical center line of urceolus 3 and inner core 1 crosses directly over the longitudinal center line of urceolus 3 and inner core 1.The ventilation duct center line passes through the center of circle in inner core upper half part on the inner core 1 by making for it, lower half portion ventilation duct center line intersection point skew center of circle, thereby can make the interior gas-flow resistance of blower fan runner even, avoid motor to be subjected to owing to the inhomogeneous alternate load that causes of gas-flow resistance in the runner.Ventilation duct 2 is a supporting element, is again the passage of motor radiating air-flow simultaneously.Inner core can be avoided owing to rotated by impeller and the air-flow effect causes turns round shake in lower half portion ventilation duct center line intersection point skew center of circle.Consult Fig. 1 and Fig. 2.
Embodiment 2, and the distance of the longitudinal center line of joint and urceolus 3 or inner core 1 is less than the internal diameter of inner core 1 directly over the shaft axis elongation line of 2 ventilation ducts 2 in bottom of the present utility model and the longitudinal center line of urceolus 3 or inner core 1.The distance of the shaft axis extending line intersection point skew urceolus 3 of 2 ventilation ducts 2 in bottom or the longitudinal center line of inner core 1 can be according to processing parameter setting.Consult Fig. 1 and Fig. 2, all the other are with embodiment 1.
