Abstract
The invention provides a thermal circulation fan, belonging to the manufacture technical field of a fan. The thermal circulation fan is mainly composed of an impeller (4), a motor (10) with an oil injection pipe (9), a sealing plate (5) which is provided with a thermal insulation cone (8) and arranged between the impeller (4) and the motor (10), an internal fan drum (3) and an external fan drum (1) which are respectively arranged at the front end and the periphery of the impeller (4), a rear guide vane (2) which is arranged between the external fan drum (1) and the internal fan drum (3),a front guide vane (7) which is arranged between the external fan drum (1) and the thermal insulation cone (8), a cooling fan (6) which is arranged between the front of the motor (10) and a sealing plate (5), etc. The whole structure of the thermal circulation fan has reasonable design, and the heat is effectively insulated between the fan thermal airflow and the motor through the thermal insulation cone; the thermal circulation fan can be provided with the cooling fan on a motor shaft and can be provided with the oil injection pipe on a front bearing and a rear bearing, thus ensuring the normal run of the motor. Furthermore, the fan impeller and the vane is made of casting aluminium alloy material which can meet the application requirement of the thermal circulation fan.
Description
Technical field
The present invention relates to a kind of thermal circulation fan, belong to the manufacturing technology field of blower fan.
Background technique
Thermal circulation fan is the important matching parts of paper industry pulpboard hot air dryer, and the thermal cycle that also can be used for other air temperatures and be 150 ℃-180 ℃ is ventilated.Existing thermal circulation fan is mainly by outer air duct, and formations such as stator, impeller, motor because structure and technical performance are poor, can't satisfy the needs of coordinative composition of equipments.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in designly, compact structure can effectively be carried hot air, reliably and with long-term the thermal circulation fan of Zheng Changyunzhuaning.
The present invention is a thermal circulation fan, comprises the axial-flow blower that is made of impeller and motor, it is characterized in that being provided with between impeller and the motor sealing plate with heat insulation cone, and motor is fixed in the heat insulation cone; Air duct and outer air duct were provided with rear guide vane between outer air duct and the interior air duct in the front end of impeller and periphery were respectively equipped with, and were provided with preceding stator between outer air duct and the heat insulation cone.
Also can be provided with cooling fan between the front end of described motor and the sealing plate.
Also can be provided with oil filler pipe on the described motor, can the front and back bearings on motor refuel.
The material of described impeller and cooling fan upper blade can be pack alloy.
The present invention is reasonable in design, and compact structure is effectively heat insulation by heat insulation cone between blower fan hot air flow and motor; Also can on motor reel, carry cooling fan and front and back bearings band oil filler pipe, guarantee the normal operation of motor.Draught fan impeller and blade adopt cast aluminium alloy material then more can satisfy the usage requirement of thermal circulation fan.
Description of drawings
Accompanying drawing has provided overall structure schematic representation of the present invention.
Embodiment
The present invention is mainly by the motor 10 of impeller 4 with band oil filler pipe 9, place between impeller 4 and the motor 10 sealing plate 5 with heat insulation cone 8, place impeller 4 front ends and peripheral interior air duct 3 and outer air duct 1 respectively, place the rear guide vane 2 between outer air duct 1 and the interior air duct 3, place the preceding stator 7 between outer air duct 1 and the heat insulation cone 8, place the formations such as cooling fan 6 between motor 10 front ends and the sealing plate 5.Heat insulation cone 8 is installed in the intake grill of axial-flow blower, and motor 10 places in heat insulation cone 8 normal temperature one side, hot-flow flue and motor 10 heat insulation coming.The material of impeller 4 and cooling fan 6 upper blades is a pack alloy.The intake grill of outer air duct 1 is similar slip ring shape, the enlarging shape that exhaust outlet closes up for the band rear portion.
During use, the present invention is installed on paper industry pulpboard hot air dryer or other need on the equipment of heated air circulation, and installs vent passages on request.Connect power supply, motor 10 runnings, impeller 4 running air-supplies, the hot air that comes out from heater 11, enter the preceding stator 7 of air inlet, through motor 10 drives impeller 4 hot air is drained in the heater 11 again, thereby forms the hot air circulate of arrow 12 indication airflow directions as shown in drawings.Motor 10 is isolated by heat insulation cone 8 and hot air, on the axle of unique motor that contact with hot air 10 cooling fan 6 is installed, and is used for cool motors 10 fore bearings to conduct the heat of coming with dispersing from sealing plate 5.
