Abstract
The invention discloses a high-temperature resistant fan for a furnace. The fan comprises a fan shell, a variable frequency motor and an impeller cover, wherein the bottom surface of the fan shell is fixedly connected with the top surface of the impeller cover; a main shaft base is arranged in the fan shell; a main shaft is arranged on the main shaft base; the top of the main shaft penetrates through the top surface of the fan shell, and is movably connected with the variable frequency motor through a belt wheel; a cooling fan is arranged on the variable frequency motor; the bottom of the main shaft penetrates through the bottom surface of the fan shell, and extends into the impeller cover; an impeller is arranged at the bottom end of the main shaft; a plug body encircling the main shaft base and the main shaft is arranged in the fan shell; and a water cooling sleeve is arranged on the outer wall of the plug body. The high-temperature resistant fan for the furnace has the following beneficial effects: the equipment is simple in structure and convenient for use, and can effectively increase the ventilation quantity, shorten the heating time and enable the fan to be operated in a high-temperature environment for a long time for quickly cooling, so that the service life of the fan is prolonged, the maintenance consumption is reduced, and the production efficiency is improved.
Description
(1) technical field
The present invention relates to a kind of exhaust equipment, particularly relate to a kind of stove resisting blower.
(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, especially oven, annealing furnace, soaking pit, the fast development especially of the heat treatment installations such as aging furnace, in the heat treatment installations such as existing industrial furnace, blower fan is all installed, along with the increase of industrial furnace treating capacity, in particular for formula roasting oven work at the bottom of carbon element car, current relatively more conventional axial fan flow and pressure do not reach usage requirement, need of production can not be met, the effect shortened heating time and enhance productivity can not be played, in addition, blower fan runs for a long time in high temperature environments, can shorten its working life, the number of times increasing maintenance and replacing and expense.On the market can stronger ventilation amount, shorten heating time, make blower fan be in hot environment for a long time simultaneously under fast cooling when running, thus prolongation service life of fan, reduce maintenance to consume, the blower fan of enhancing productivity also is not 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 stove resisting blower.
Technological scheme of the present invention realizes like this.
A kind of stove resisting blower of this programme, comprises Blower Housing, variable-frequency motor and impeller outer cover, and described Blower Housing bottom surface is fixedly connected with impeller outer cover end face; Described Blower Housing inside is provided with main shaft base; Described main shaft base is provided with main shaft, and this spindle top is passed Blower Housing end face and is flexibly connected by belt pulley with variable-frequency motor; Described variable-frequency motor is provided with cooling blower; Stretch into impeller outer cover through Blower Housing bottom surface bottom described main shaft inner, described main shaft bottom is provided with impeller; Described Blower Housing inside is provided with cock body around main shaft base and main shaft, and this cock body inside is filled with heat insulation foam; Described cock body end face is fixedly connected with Blower Housing end face; Described cock body outer wall is provided with water jacket, is provided with water inlet bottom this water jacket, and described water jacket top is provided with water outlet.
Aluminosilicate fiber cotton is filled in described cock body inside.
Described impeller adopts silicon carbide alloys material.
Usefulness of the present invention is: this device structure is simple, easy to use, effectively can strengthen blower ventilation amount, shorten heating time, carry out fast cooling when running under blower fan can being made to be in hot environment for a long time simultaneously, thus prolongation service life of fan, reduce maintenance to consume, enhance productivity.
(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.
A kind of stove resisting blower as shown in drawings, comprises Blower Housing 1, variable-frequency motor 2 and impeller outer cover 7, and described Blower Housing 1 bottom surface is fixedly connected with impeller outer cover 7 end face; Described Blower Housing 1 inside is provided with main shaft base 4; Described main shaft base 4 is provided with main shaft 5, and this main shaft 5 top is passed Blower Housing 1 end face and is flexibly connected by belt pulley 8 with variable-frequency motor 2; Described variable-frequency motor 2 is provided with cooling blower 9; Stretch into impeller outer cover 7 through Blower Housing 1 bottom surface bottom described main shaft 5 inner, described main shaft 5 bottom is provided with impeller 3; Described Blower Housing 1 inside is provided with cock body 6 around main shaft base 4 and main shaft 5, and this cock body 6 inside is filled with heat insulation foam; Described cock body 6 end face is fixedly connected with Blower Housing 1 end face; Described cock body 6 outer wall is provided with water jacket 10, is provided with water inlet 11 bottom this water jacket 10, and described water jacket 10 top is provided with water outlet 12.
Aluminosilicate fiber cotton is filled in described cock body 6 inside.
Described impeller 3 adopts silicon carbide alloys material.
The working procedure of this example: when using this device, first this device is arranged in formula roasting oven at the bottom of carbon element car, open variable-frequency motor 2, variable-frequency motor 2 drives main shaft 5 to rotate by belt pulley 8, thus make impeller 3 start to rotate, blower fan is started working air-supply, open cooling blower 9 pairs of variable-frequency motors 2 to lower the temperature, reduce variable-frequency motor 2 rate of fault, extend variable-frequency motor 2 working life, then cooling liquid is passed into from water inlet 11, cooling liquid enters water jacket 10, water jacket 10 and cock body 6 acting in conjunction are lowered the temperature to main shaft 5, thus prevent main shaft 5 overheated, aluminosilicate fiber cotton is filled in cock body 6 inside, thus higher cooling and effect of heat insulation are provided, impeller 3 adopts silicon carbide alloys material, higher intensity and heat resistance can be possessed, can effectively strengthen blower ventilation amount, shorten heating time, enhance productivity.
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.
