Abstract
The utility model relates to an air lock door sealer, which is characterized in that the air lock door sealer is composed of a door body, a door frame, a pressed frame, a guiding frame and an automatic lifting device, wherein the door body is connected with the pressed frame through springs and screw bolts, the side face of the pressed frame is provided with a guide roller, the pressed frame is connected with the guiding frame through the side guide roller, the side face of the guiding frame is also provided with a guide roller and is connected with a guide rail through the guide roller, the guide rail is arranged on a steel structure of the sealer and the automatic lifting device is connected with the guiding frame. The utility model has the advantages that the structure is simple, a set of door lifting device not only can complete the lifting action of the door but also can complete the compressing action and the opening action of the door, the position between the door and a sealing element has no relative slide and the service life of the sealing element is long and can reach two years or more than two years.
Description
Affiliated field:
The utility model belongs to a kind of sealing door in the scale-free heating equipment, particularly a kind ofly only needs unlatching that a transmission mechanism can realize door, closes, compresses automatically and the sealing door gear of positive confinement.
Background technology:
For large-scale scale-free heating equipment,, charge into protective atmosphere in the firing equipment usually in order to prevent the oxidation of workpiece.In order to adapt to complicated product and technological requirement, firing equipment has forward and backward closed chamber or vacuum chamber, and each closed chamber or vacuum chamber need two doors.The effect of closed chamber or vacuum chamber is to make the protective atmosphere in the stove outside isolated with stove, prevents that simultaneously extraneous air from entering the interior or furnace atmosphere of stove to external leakage.Be about to because the air that air that the workpiece into of opening the door is brought into and workpiece itself contain band is replaced or extracted and drains into outdoor.The operation principle of closed chamber or vacuum chamber is as follows: the 1st step was closed closed chamber or door for vacuum chamber 2, opening encapsulation chamber or door for vacuum chamber 1; The 2nd step workpiece enters, and closes closed chamber or door for vacuum chamber 1; Displacement of the 3rd step or extraction room air are to the requirement of setting; The 4th step is to the indoor protection gas that fills; The 5th step chamber door 2 is opened, and workpiece leaves closed chamber or vacuum chamber enters in the stove.When carrying out for the 3rd step is vacuum chamber when vacuumizing, and door bears pressure outside in.When the 4th step of execution was promptly filled protection gas in vacuum chamber, door bore thrust from inside to outside.Along with the increase of fire door area, this pressure or thrust are also bigger, and therefore sealing is difficult.Traditional way is: except the lowering or hoisting gear of needs door, must increase by a cover and compress device outside closed chamber or door for vacuum chamber, adopt pneumatic, hydraulic pressure or electronic way that door for vacuum chamber is compressed.The shortcoming of this class device is: complex structure, seal life is low, is generally 6-10 month.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, only needs a transmission mechanism can realize the unlatching of door and provide a kind of, closes, and compresses the also door gear of positive confinement automatically.This fire door simple in structure, good sealing effect, long service life.
The technical solution of the utility model is: a kind of sealing door gear is characterized in that: be made up of door body, doorframe, press box, guide housing and automatic lifting device; The door body is connected with press box with bolt by spring; Guide roller is equipped with in the side of press box, and press box is connected with guide housing by the guide roller of side; The guide housing side also is equipped with guide roller and is connected with guide rail by guide roller, and guide rail is installed on the equipment steel construction, and automatic lifting device is connected with guide housing.
Above-mentioned automatic lifting device is made up of the drive sprocket that is contained in the left and right two sides of guide housing respectively, chain, limit switch and reducing motor.On the above-mentioned doorframe seal is housed.
The utility model has the advantages that: 1, simple in structure, with a cover door lowering or hoisting gear, can not only finish the lifting action of door, and can also finish door compress/throw off action.2, the door with seal between do not have relative slip, the life-span of seal is long, can reach 2 years even longer.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
The specific embodiment:
Be connected on the steel construction of chamber through precision machined closed chamber or vacuum chamber doorframe (1) pressure-tight weld, seal (3) is housed on the doorframe, door (2) is connected on the press box (6) by spring and bolt, be contained in guide roller (5) on the press box (6) and promptly finish the lateral positioning function of press box, when also playing door (2) and closing or open forward to doorframe (1) backward to the guide effect of leaving doorframe (1) lateral displacement.
The guide roller (7) that has the self-lubricating cover is positioned on the side of guide housing (4), and it can move up and down along the groove on the guide rail (8), plays the guide effect of a lifting.
Door (2), press box (6) and guide housing (4) are all driven by sprocket wheel (9), sprocket wheel (13), roller chain (10), (11) and reducing motor (12) and move up and down, and roller chain (10) and (11) are contained in guide housing (4) left side and the right side separately.
Moving up and down of door by limit switch control, and the protection hoisting mechanism is not damaged.
When opening door (2), guide housing (4) is raised, be in simultaneously that guide roller (5) slides to lowest order along chute (14) by a high position on chute (14) high position on the guide housing (4), door (2) steadily leave doorframe (1) traversing backward and seal (3) throw off certain distance after, just begin to move up, door is raised.
When door (2) when being thus lifted to correct height, limit switch sender, the fire door motor is out of service.
When door (2) when being closed, door (2), press box (6) and guide housing (4) move down, on the limited block below press box (6) arrives, door (2), press box (6) stop to move down, guide housing (4) continues to move down, make the low level of the chute (14) of guide roller (5) from the press box (6) be raised to a high position, door (2) steadily is moved to forward on the seal (3) that is pressed on doorframe (1) lining, this moment, door was fastened.
Claims (3)
1, a kind of sealing door gear is characterized in that: be made up of door body, doorframe, press box, guide housing and automatic lifting device; The door body is connected with press box with bolt by spring; Guide roller is equipped with in the side of press box, and press box is connected with guide housing by the guide roller of side; The guide housing side also is equipped with guide roller and is connected with guide rail by guide roller, and guide rail is installed on the equipment steel construction, and automatic lifting device is connected with guide housing.
2, sealing door gear according to claim 1 is characterized in that: above-mentioned automatic lifting device is made up of the drive sprocket that is contained in the left and right two sides of guide housing respectively, chain, spacing outer pass and reducing motor.
