Abstract
A high-temperature-resisting negative pressure fan comprises a motor, a fan shell and a main shaft; one end of the main shaft is fixedly connected with the motor, and the main shaft stretches into the fan shell and is movably connected with the side wall of the fan shell; an impeller is arranged at the tail end of the main shaft, and an air outlet is formed in the bottom end of the outer wall of the fan shell; a plug body is arranged on the inner wall of the fan shell, and the plug body is filled with heat insulation cotton; and a water cooling jacket is arranged on the outer wall of the plug body. The high-temperature-resisting negative pressure fan has the beneficial effects that the negative pressure fan is simple in equipment structure, easy and convenient to use, and capable of effectively discharging waste gas in an aluminum roll annealing industrial furnace, and the product quality is improved; the temperature of the fan can be effectively reduced; the fan can work in the high-temperature area for a long time, and the main shaft cannot be clamped due to too high temperature; meanwhile, the phenomenon that due to high-temperature overheating, the motor of the fan is damaged is avoided, and therefore the service life of the fan is prolonged; and equipment maintenance cost is reduced.
Description
(1) technical field
The present invention relates to a kind of exhaust equipment, particularly relate to a kind of high temperature resistant negative-pressure air fan.
(2) background technique
At present, in recent years along with the fast development of national economy, be that the non-ferrous metals processing industry of representative achieves development at full speed with Aluminum, the process equipment industry of non-ferrous metal has also had larger development thereupon, meanwhile, also more and more higher to the requirement of process equipment.Nowadays in the using process of aluminium volume annealing industrial furnace, ROLLING OIL evaporation when furnace temperature reaches about 300 DEG C in aluminium volume incorporates in furnace gas, in order to discharge ROLLING OIL flue gas in stove, improve the quality of products, spy adds negative pressure smoke exhaust fan on body of heater, and traditional blower fan is when working in high temperature environments, due to Long contact time high-temperature zone, be easy to make electric machine main shaft because of overheated and locking, the motor of blower fan is also easy to damage because of hyperthermia and superheating, shorten the working life of blower fan, too increase the expense of maintenance of equipment simultaneously.Effectively can discharge the waste gas in aluminium volume annealing industrial furnace on the market, improve the quality of products, and can effectively reduce blower fan temperature, make blower fan can not make the too high locking of main shaft Yin Wendu in high-temperature zone work for a long time, avoid the motor of blower fan to damage because of hyperthermia and superheating simultaneously, thus prolongation service life of fan, the blower fan reducing device maintenance expense is not also found, and awaits exploitation.
(3) summary of the invention
In order to overcome the deficiency of existing exhaust equipment, the invention provides a kind of high temperature resistant negative-pressure air fan.
Technological scheme of the present invention realizes like this.
The high temperature resistant negative-pressure air fan of one of this programme, comprises motor, Blower Housing and main shaft, and described main shaft one end is fixedly connected with motor; Described main shaft stretches into Blower Housing and is flexibly connected with Blower Housing sidewall; Described main shaft end is provided with impeller; Described Blower Housing outer wall bottom is provided with exhaust outlet; Described Blower Housing inwall is provided with cock body, and this cock body inside is filled with heat insulation foam; Described cock body outer wall is provided with water jacket.
Stuffed heat insulated cellucotton in described cock body.
Described impeller is centrifugal impeller.
Described motor is direct connection major axis heat resisting motor.
Usefulness of the present invention is: this device structure is simple, easy to use, effectively can discharge the waste gas in aluminium volume annealing industrial furnace, improve the quality of products, and can effectively reduce blower fan temperature, make blower fan can not make the too high locking of main shaft Yin Wendu in high-temperature zone work for a long time, avoid the motor of blower fan to damage because of hyperthermia and superheating simultaneously, thus extend service life of fan, reduce device maintenance expense.
(4) accompanying drawing explanation
Fig. 1 is front sectional view of the present invention.
(5) embodiment
Below in conjunction with accompanying drawing, brief description is made to the specific embodiment of the present invention.
One as shown in drawings is high temperature resistant negative-pressure air fan, comprise motor 1, Blower Housing 2 and main shaft 3, described main shaft 3 one end is fixedly connected with motor 1; Described main shaft 3 stretches into Blower Housing 2 and is flexibly connected with Blower Housing 2 sidewall; Described main shaft 3 end is provided with impeller 5; Described Blower Housing 2 outer wall bottom is provided with exhaust outlet 4; Described Blower Housing 2 inwall is provided with cock body 6, and this cock body 6 inside is filled with heat insulation foam; Described cock body 6 outer wall is provided with water jacket 7.
Stuffed heat insulated cellucotton in described cock body 6.
Described impeller 5 is centrifugal impeller.
Described motor 1 is direct connection major axis heat resisting motor.
The working procedure of this example: when using this device, first Blower Housing 2 is arranged on aluminium volume annealing industrial furnace roof portion outer wall, then motor 1 is opened, motor 1 rotates the impeller 5 driving main shaft 3 and be arranged on main shaft 3 end and rotates simultaneously, the flue gas of furnace interior can be extracted out and discharge furnace interior from exhaust outlet 4, thus improve the quality of products, impeller 5 selects centrifugal impeller, in order to can flue gas be discharged, this centrifugal impeller is the design of high blast, direct connection major axis heat resisting motor selected by motor 1 simultaneously, simultaneously due to Blower Housing 2 being provided with cock body 6, the heat contained in the flue gas that the heat insulation fiber cotton that this cock body 6 inside is filled can effectively avoid furnace interior and impeller 5 to extract out is delivered in motor 1, motor 1 is avoided to damage because of hyperthermia and superheating, simultaneously due to cock body 6 outer wall being provided with water jacket 7, effectively can reduce the temperature of Blower Housing 2 inside, thus protection main shaft 3 can not because of the too high locking of temperature in high-temperature zone work for a long time, thus prolongation service life of fan, reduce device maintenance expense.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
