Description
Technical field
The utility model relates to kiln technical field, in particular, and particularly a kind of furnace door lifting device of reverberatory furnace.
Background technology
Anode copper melting be the composition brass that gives up be that raw material obtains anode copper through pyro-refining, useless composition brass includes that red copper, brass, bronze, copper-nickel alloy etc. are various take copper as basic alloy.The process of melting generally comprises fusing, oxidation and reduction three phases, and all processes carries out in reverberatory furnace.The object of refining is to remove copper alloying component in addition, such as: Zn, Pb, Sn, Mn etc., and then obtain the anode copper that copper content is greater than 98.8%, and the basic principle of removing above impurity is based on copper, the affinity of oxygen to be less than the elements such as lead, zinc, nickel, arsenic, tin, antimony.Adopting copper in composition brass pyro-refining process is a large amount of existence, and impurity element is micro-, and therefore, copper is first oxidized to Cu
2o, then Cu
2o passes to impurity element by oxygen, makes impurity element oxidation (impurity element also has partial direct oxidation), the oxide emersion bath surface that metal impurities are oxidized out, or volatilization enters flue gas, or with the solvent slag making adding, thereby separated with copper melts.Because the melting of reverberatory furnace is to carry out in the environment of sealing, and the fire door of existing reverberatory furnace generally adopts and manually closes and open, and the problem existing is like this: labor strength greatly, poor stability, efficiency be low.Meanwhile, Ye You producer adopts motor and rope to carry out automatic lifting, but because fire door is to carry out frequently opening and closing, easily causes reduce the fatigue life of rope, needs regularly rope to be changed, and easily causes potential safety hazard.
Utility model content
The purpose of this utility model is, for the technical problem that has poor stability in prior art, to provide a kind of furnace door lifting device.
In order to solve problem set forth above, the technical solution adopted in the utility model is: a kind of furnace door lifting device, comprise doorframe and fire door, the both sides of described doorframe are provided with guide rail, and the both sides of described fire door are provided with the roller coordinating with guide rail, the top of described doorframe is provided with motor, the worm screw being connected with motor, with the turbine of worm engaging, and one end and the eccentric expansion link being connected of turbine, the other end of this expansion link is connected with a slide block, and described slide block is installed on the inner side of fire door.
According to a preferred embodiment of the present utility model: the inner side of described fire door is provided with chute, and described slide block is installed in chute.
According to a preferred embodiment of the present utility model: described worm screw is installed on the top of doorframe by a bearing block.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts turbine and worm to realize the lifting to fire door, abandon the automatic lifting method of existing employing rope, extended the service life of furnace door lifting device, reduced potential safety hazard.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Consult shown in Fig. 1-Fig. 3, the utility model provides a kind of furnace door lifting device, comprise doorframe 10 and fire door 40, wherein: in the both sides of doorframe 10, be provided with guide rail 20, and in the both sides of fire door 40, be provided with the roller 30 coordinating with guide rail 20, the top of doorframe 10 is provided with motor 50, the worm screw 60 being connected with motor 50, turbine 70 with worm screw 60 engagements, and one end and the eccentric expansion link 80 being connected of turbine 70, the other end of this expansion link 80 is connected with a slide block 90, and described slide block 90 is installed on the inner side of fire door 40.
In use, by starter motor 50, drive worm screw 60 and turbine 70 to rotate, and because expansion link 80 is connected with turbine 70 is eccentric, when turbine 70 rotates, expansion link 80 and slide block 90 promote (unlatching) and (closing) fire door 40 that declines back and forth, have reached door opened and requirement that close.
Specifically in use, diameter of the length of expansion link 80, turbine 70 etc. can be carried out different selections according to the size of fire door 40.
And in order further to improve the opening and closing effect to fire door 40, the inner side of fire door 40 is provided with chute 100, described slide block 90 is installed in chute 100, and closely cooperates with chute 100.
Described worm screw 60 is installed on the top of doorframe 10 by a bearing block.
And for convenience of controlling and the energy-conservation energy, motor 50 also can be connected with frequency converter.
The quantity of the roller 30 in the utility model can be set according to the size of fire door 40.
The utility model has the advantage of: 1, adopt turbine and worm to realize the lifting to fire door, abandoned the automatic lifting method of existing employing rope, extended the service life of furnace door lifting device, reduced potential safety hazard; 2, employing is provided with roller 30, in the both sides of doorframe 10, is provided with guide rail 20 in the both sides of fire door 40, can make fire door 40 more convenient and stable in promoting (unlatching) and (closing) process of decline; 3, simple in structure, easy to operate, cost is low.
Above-described embodiment is preferably embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
