Abstract
The utility model discloses a volute type high-temperature-resistant centrifugal impeller fan which comprises a motor, a fan casing and a transmission shaft, wherein the fan casing is volute-shaped; one end of the transmission shaft is connected with the motor through a belt wheel; the transmission shaft passes through the center of one side wall of the fan casing to extend into the fan casing; an impeller is arranged at the tail end of the transmission shaft; an air outlet is formed in the tail end surface of the fan casing; an air inlet is formed in one side wall of the fan casing, unconnected with the transmission shaft; a plug body is arranged on the transmission shaft between the motor and the fan casing; an air cooling wheel is arranged on the transmission shaft between the plug body and the motor. The centrifugal impeller fan has the benefits that the structure is simple, the operation is easy and convenient, the flow volume of the fan can be increased, the heat transmitted to the motor from a furnace body is effectively reduced, the temperature can be quickly reduced, the locking phenomenon of a main shaft of the fan due to excessively high temperature is avoided, the motor temperature of the fan is reduced, the motor scrapping due to overheat is prevented, the production cost is saved, and the service life of the fan is prolonged.
Description
(1) technical field
The utility model relates to a kind of exhaust equipment, particularly relates to the high temperature resistant centrifugal impeller blower fan of a kind of scroll casing type.
(2) background technique
At present, in recent years along with the fast development of national economy, non-ferrous metals processing industry take Aluminum as representative has obtained development at full speed, along with the raising of the increase of industrial furnace quantity and the requirement to product treatment quality, the blower fan matching with it also needs to meet the different technical requirementss such as large flow.Nowadays in the process of non-ferrous metals processing, need to heat to air draft in relevant body of heater by blower fan, but present compressor flow is too low, can not make temperature in stove raise fast, thereby the efficiency of heating surface is reduced, simultaneously due to the blower fan high-temperature zone in body of heater for a long time, therefore main shaft is easy to produce locking phenomenon because of excess Temperature, heat in body of heater is also easy to be delivered on motor, motor overheating is scrapped, cause equipment loss, reduced the working life of blower fan, improved cost of production.Can strengthen on the market compressor flow, effectively reduce body of heater internal heat to motor transmission, simultaneously can fast cooling, avoid blower fan main shaft to produce locking phenomenon because of excess Temperature, reduce the motor temperature of blower fan, prevent that motor overheating from scrapping, save production cost, the blower fan increasing the service life is not also found, and awaits exploitation.
(3) model utility content
In order to overcome the deficiency of existing exhaust equipment, the utility model provides a kind of scroll casing type high temperature resistant centrifugal impeller blower fan.
The technical solution of the utility model is to realize like this.
The high temperature resistant centrifugal impeller blower fan of a kind of scroll casing type of this programme, comprises motor, Blower Housing and transmission shaft, and described Blower Housing is scroll casing shape; Described transmission shaft one end is connected by belt pulley with motor; Described transmission shaft is stretched into Blower Housing inside and is flexibly connected with Blower Housing sidewall by Blower Housing one side sidewall central position; Described transmission shaft end is provided with impeller; Described Blower Housing end surface is provided with exhaust outlet; On the side sidewall that described Blower Housing is not connected with transmission shaft, be provided with intake grill; Transmission shaft between described motor and Blower Housing is provided with cock body near Blower Housing place; On transmission shaft between described cock body and motor, be provided with air-cooled wheel.
Described motor is variable-frequency motor.
Described cock body inside is filled with heat insulation fiber cotton.
Described impeller is that three layers of centrifugal impeller are welded.
Usefulness of the present utility model is: this device structure is simple, easy to use, can strengthen compressor flow, effectively reduce body of heater internal heat to motor transmission, simultaneously can fast cooling, avoid blower fan main shaft to produce locking phenomenon because of excess Temperature, reduce the motor temperature of blower fan, prevent that motor overheating from scrapping, save production cost, extend service life of fan.
(4) accompanying drawing explanation
Fig. 1 is that master of the present utility model looks sectional view.
Fig. 2 is right elevation of the present utility model.
(5) embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is made to brief description.
The high temperature resistant centrifugal impeller blower fan of scroll casing type, comprises motor 1, Blower Housing 2 and transmission shaft 6 as shown in drawings, and described Blower Housing 2 is scroll casing shape; Described transmission shaft 6 one end are connected by belt pulley 3 with motor 1; Described transmission shaft 6 is stretched into Blower Housing 2 inside and is flexibly connected with Blower Housing 2 sidewalls by Blower Housing 2 one side sidewall central positions; Described transmission shaft 6 ends are provided with impeller 5; Described Blower Housing 2 end surface are provided with exhaust outlet 4; On the side sidewall that described Blower Housing 2 is not connected with transmission shaft 6, be provided with intake grill 8; Transmission shaft 6 between described motor 1 and Blower Housing 2 is provided with cock body 7 near Blower Housing 2 places; On transmission shaft 6 between described cock body 7 and motor 1, be provided with and air-cooledly take turns 9.
Described motor 1 is variable-frequency motor.
Described cock body 7 inside are filled with heat insulation fiber cotton.
Described impeller 5 is that three layers of centrifugal impeller are welded.
The working procedure of this example: while using this device, first fan main body 2 is arranged on the body of heater of Nonferrous Metal Forming, Blower Housing 2 is stretched into body of heater inside, by the scroll casing type design of Blower Housing 2, can strengthen to a certain extent exhaust air rate, then open motor 1, motor 1 drives the rotation of transmission shaft 6 by belt pulley 3, rotate by transmission shaft 6 impeller 5, thereby then air is sucked and discharged from exhaust outlet 4 from intake grill 8, because impeller 5 is that three layers of centrifugal impeller are welded, strengthen greatly the blast of impeller, also promoted bulk flow, promote the efficiency of heating surface, owing to being arranged on cock body 7 on transmission shaft 6 and air-cooledly taking turns 9 existence, can effectively disperse, the heat of the body of heater inside that isolated transmission shaft 6 absorbs, therefore can avoid blower fan main shaft to produce locking phenomenon because of excess Temperature, the inner heat insulation fiber cotton of filling of cock body 7 can be by the heat absorption of body of heater inside, air-cooled 9 can the leave heats on transmission shaft 6 carry out cooling to transmission shaft 6 of taking turns, reduce the heat transmitting to motor 1 in body of heater, thereby reduce the motor temperature of blower fan, prevent that motor overheating from scrapping, save production cost, extend service life of fan.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
