The top surface of the furnace body is provided with an air pressure device, the bottom of the furnace body is provided with a hydraulic device, and the furnace door can be opened and closed by the push-and-pull match between the hydraulic device and the air pressure device, so that the furnace door is stable in operating and tight in sealing when furnace door is opened and closed, a furnace door operating mechanism is simplified, and the stability of the operation and the tightness of the sealing of the furnace door can be improved; and the air pressure device is matched with the hydraulic device up and down, so that the furnace door can be even in stress, the service life of the furnace door can be guaranteed, the maintenance times of the furnace door can be reduced, the enterprise production cost can be reduced, and the labor intensity of workers can be lightened.
Description
Technical field:
The utility model belongs to industrial kiln technical field, is specifically related to a kind of door opened industrial kiln fire door mechanism of kiln that makes things convenient for.
Background technology:
In existing technology, the fire door mechanism of industrial kiln adopts motor to move by chain drive fire door more or hydraulic cylinder moves by chain drive fire door, realize the open and close of fire door, these two kinds of fire door mechanisms are necessary for fire door motion guide rail are set specially, when guide rail is longer, the guide rail foundry goods needs the segmentation assembling, and often operation is unstable in motion process, walking is not smooth for fire door like this; Problem such as also can occur unbalance stress in addition, to compress sealing bad, and service life is short.
The utility model content:
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of industrial kiln fire door mechanism, it is at the body of heater end face pneumatic shuttle to be set, and at bottom of furnace body hydraulic means is set, by the push-and-pull cooperation of hydraulic means and pneumatic shuttle, realize the opening and closing of fire door, thereby make door opened and operate steadily when closing, seal tight, both simplified the fire door travelling mechanism, improved the tightness of fire door running stability and sealing again.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of industrial kiln fire door mechanism, comprise body of heater and fire door, wherein: described fire door both sides are provided with retainer ring, be coated with guide post in the retainer ring, the body of heater bottom is provided with down linking arm, and the guide post lower end is hinged with following linking arm, the body of heater end face is provided with cylinder, the guide post upper end is hinged with the piston rod of cylinder, and following linking arm is provided with hydraulic cylinder, and the piston rod and the retainer ring of hydraulic cylinder are hinged.
Further, described fire door both sides respectively are provided with two retainer rings, and retainer ring arranges that up and down the retainer ring on top and the piston rod of hydraulic cylinder are hinged.
Further, described guide post and retainer ring flexibly connect.
Further, described cylinder and body of heater end face are hinged.
Further, described hydraulic cylinder is hinged with following linking arm.
The beneficial effects of the utility model are:
1, the utility model is at the body of heater end face pneumatic shuttle to be set, at bottom of furnace body hydraulic means is set, push-and-pull by hydraulic means and pneumatic shuttle cooperates, realize the opening and closing of fire door, thereby make door opened and operate steadily when closing, seal tight, both simplify the fire door travelling mechanism, improved the tightness of fire door running stability and sealing again.
2, the utility model is simple and compact for structure, and is easy to use, the cost cost is low, and pneumatic shuttle and hydraulic means are used up and down simultaneously, make fire door stressed evenly, thereby guarantee the service life of fire door, reduce fire door maintenance maintenance number of times, reduce enterprise's production cost, reduce labor strength.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cross-sectional schematic of the utility model Fig. 1.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of industrial kiln fire door mechanism comprises body of heater 1 and fire door 2, and fire door 2 both sides are respectively arranged with two retainer rings 4, two retainer rings 4 are arranged up and down, be coated with guide post 3 in the retainer ring 4, body of heater 1 bottom surface is fixed with down linking arm 6, and guide post 3 lower ends and following linking arm 6 are hinged, be hinged with cylinder 7 on body of heater 1 end face, the piston rod of guide post 3 upper ends and cylinder 7 is hinged, is hinged with hydraulic cylinder 5 on the following linking arm 6, and the piston rod of hydraulic cylinder 5 and the retainer ring on top 4 are hinged.
When fire door 2 was closed, hydraulic cylinder 5 was in elongation state, and furnace roof cylinder 7 is in contraction state, and cylinder 7 makes fire door 2 compress body of heater 1 by guide post 3 being applied pulling force; When fire door 2 was prepared to open, cylinder 7 began elongation, and guide post 3 is tilted away from body of heater 1, and then hydraulic cylinder 5 begins to start, and pulling fire door 2 is walked downwards along guide post 3, and hydraulic cylinder 5 operations put in place, and fire door 2 is steadily opened; When once more closed fire door 2, hydraulic cylinder 5 promotes fire doors 2 earlier and moves upward hydraulic cylinder 5 and fire door 2 stop motions when motion puts in place along guide post 3, then furnace roof cylinder 7 starts, and pulling guide post 3 makes fire door 2 press close to body of heater 1 near body of heater 1, and compress, cylinder 7 stops when putting in place when compressing; This process has been finished the switching motion of fire door 2.
Be noted that, the above embodiment is to the explanation of technical solutions of the utility model and unrestricted, other modification that is equal to replacement or makes of affiliated technical field those of ordinary skill according to prior art, as long as do not exceed the thinking and the scope of technical solutions of the utility model, all should be included within the desired interest field of the utility model.
