Abstract
The utility model relates to the field of fans, in particular to a low-temperature fan inlet flow adjusting device. The low-temperature fan inlet flow adjusting device comprises an outer cylinder, an inner cylinder, guide vanes, a thermal insulation layer and drive motors. The inner cylinder is fixedly mounted in the outer cylinder through plates. The outer cylinder is coaxial with the inner cylinder. An incoming flow direction end of the inner cylinder is of a streamline shape. The guide vanes are circumferentially evenly distributed between the outer cylinder and the inner cylinder. The guide vanes are symmetrical wing-shaped guide vanes along the radial section of the outer cylinder. The thermal insulation layer covers on the outer wall of the outer cylinder. The drive motors are disposed in the inner cylinder and matched with the guide vanes in a one-to-one correspondence manner. An output shaft of each drive motor penetrates through the inner cylinder to be connected with the bottom of the corresponding vane. A certain gap is reserved between the top of each guide vane and the outer cylinder. The low-temperature fan inlet flow adjusting device has the advantages that openness of the guide vanes is changed uniformly to adjust flow, the top of each guide vane is not communicated with the outer cylinder to achieve complete top airtightness of the guide vanes, working medium leakage of the guide vane tops is zero, a cold bridge which causes damage of the thermal insulation layer forms less easily, and service life of the thermal insulation layer is prolonged.
Description
Technical field
The utility model relates to the ventilator field, relates in particular to a kind of ventilator inlet flow adjustment device.
Background technique
Ventilator can be carried gas and improve gas pressure, is widely used in the mining of national economy, metallurgy, chemical industry, refrigeration, power and the industry such as metallurgical.When work system needs gas flow to reduce, generally change the gas flow that enters work system by regulating the outlet valve opening.Such rate of discharge controlling device reduces rate of discharge because increasing resistance to flow output, increase operating cost, the inlet flow rate controlling device changes flow by the gas flow that change enters in the ventilator, operating cost is low than the rate of discharge controlling device, thereby the inlet flow rate controlling device is used widely in the working site.
Existing inlet flow rate controlling device, its motor adjustment mechanism is often for being enclosed within diameter on the urceolus greater than lead ring or the tooth bar of urceolus external diameter, and the power unit that drives lead ring or tooth bar is again at the space outerpace of lead ring tooth bar, the stator top rotatingshaft of this class formation all outside drum outer wall expose, when working medium is cryogenic gas, easily form cold bridge at this position, the heat exchange between working medium and external environment is become frequently, thereby cause that thermal-protective coating damages.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of low temperature blower inlet flow regulator, and the wicket gate stem of this flow regulator does not pass urceolus, and stator top working medium amount of leakage is zero, is difficult for forming cold bridge and causes that thermal-protective coating damages.
The utility model is achieved in that a kind of low temperature blower inlet flow regulator, comprise urceolus, inner core, stator, thermal-protective coating and drive motor, described inner core is fixedly mounted in the urceolus by sheet material, urceolus is coaxial with inner core, the flow path direction end profile of coming of inner core is streamline, described stator circumferentially is distributed between urceolus and the inner core, stator along outer cylinder diameter to the cross section be the symmetrical airfoil stator, described thermal-protective coating covers the outer wall of urceolus, described drive motor is arranged in the inner core, drive motor is corresponding supporting one by one with stator, and the output shaft of drive motor passes inner core and links to each other with the stator bottom, leaves certain interval between the top of stator and the urceolus.
Described all drive motor all are connected with a synchronizing signal, the unified stator angle of regulating.
The utility model low temperature blower inlet flow regulator drives the stator rotation by the individual motor axle, and all drive motor are by the unified stator of regulating of a synchronizing signal, thus unified guide vane opening, the adjust flux of changing; Drive motor places inner core inner in this flow regulator in addition, makes more compact structure, has reduced the space hold volume of whole inlet flow rate controlling device; The stator top does not connect urceolus, has solved the problem of stator top seal fully, and stator top working medium amount of leakage is zero, and the insulation pack coating is wrapped in outer drum outer wall, without protruding structure, is difficult for forming cold bridge and causes that thermal-protective coating damages, and has improved working life.
