Abstract
The utility model discloses an automatic compacting and sealing mechanism for a furnace door, which comprises lifting rods which are arranged on both sides of a door body, rolling wheels and channel steel tracks which are used for installing the rolling wheels, wherein a connecting rod is connected to the position between the lifting rod and the roller through a rotating shaft, the connecting rod is connected with the side wall of the door body by a connecting pin, a block is arranged above the connecting pin of the side wall of the door body and a position limiting block is also arranged on the lower end of the channel steel track. When the furnace door is in the process of lifting, the furnace door can move along a direction which is perpendicular to a sealing surface, and the furnace door can automatically leave away or close the sealing surface, a sealing medium can not be rubbed and damaged, the furnace door can be compressed by maximum component force which is supplied by gravity in the process of compression and a fire hole has no need to be made into an inclined plane. The utility model has the advantages of artful design, reasonable design, simple structure, good sealing effect, etc., thereby, the utility model has favorable double energy-saving performance, and an additional energy source has no need to be consumed.
Description
Technical field
The utility model relates to a kind of industrial furnace fire door lifting and compresses sealing mechanism automatically, relates in particular to a kind of fire door four link type gravity and compresses sealing mechanism automatically.
Background technology
For industrial heat-treatment furnace, fire door compress the sealing be a very important ring, it is not only concerning the inherent temperature homogeneity energy of stove, and is directly connected to the energy-efficient performance of stove.
In the prior art, because the door body of industrial furnace is provided with refractory material, the door body is heavier, generally can only be parallel to the fire door vertical lift, so need to be provided with sealing mechanism on the fire door.And the oven door sealing of existing industrial furnace mostly is to adopt to add the sealing of mechanical compaction power or adopt inclined-plane gravity pressure tightening seal.The former adopts pneumatic (cylinder) or electronic (electric pushrod and so on) additional external force to compress oven door sealing, this kind mechanism good sealing effect, but shortcoming is mechanism's complexity, the more important thing is that it needs additional source of energy that power is provided, do not have energy-saving effect, increased the operating cost of stove; Though and inclined-plane gravity pressure tightening seal mechanism does not need external force to compress, energy-saving effect is better, because the component of its gravity is less, it is undesirable to compress effect, and fire door moves up and down because friction damages sealing medium, thereby causes the lost of the capacity of furnace.And because fire door need be made into the inclined-plane, not only bring difficulty, also cause unnecessary place, thereby influence the uniformity of temperature in the stove to furnace inner space to making.
The content of utility model
At existing industrial fire door mechanism above shortcomings, the fire door that the purpose of this utility model is to provide a kind of good sealing effect and does not need to consume external energy compresses sealing mechanism automatically.
The purpose of this utility model is achieved in that fire door compresses sealing mechanism automatically, comprises the groove steel rail of being located at a lifting arm of body both sides, roller and installation roller, is connected connecting rod by rotating shaft between lifting arm and the roller; Connecting rod is connected its sidewall with the door body by connecting pin; The connecting pin top of door body sidewall is provided with block; The lower end of groove steel rail also is provided with limited block.
Adopt the utility model, fire door can move along the direction perpendicular to sealing surface earlier in lifting process, leaves or draw close sealing surface automatically, and friction damage sealing medium not, and in compaction process, can provide maximum component to compress fire door, also not need fire door is made into the inclined-plane by gravity.
The utility model is skillfully constructed, reasonable in design, have simple in structure, good sealing effect and do not need to consume external energy, thereby have good advantages such as dual energy-efficient performance.
Description of drawings
Fig. 1 is structural representation of the present utility model (side-looking).
Fig. 2 is a vertical view of the present utility model.
The specific embodiment
As shown in Figure 2, fire door compresses the both sides that sealing mechanism is located at a body 8 automatically.
In conjunction with Fig. 1, fire door compresses the groove steel rail 3 that sealing mechanism comprises the lifting arm 1 of being located at a body 8 both sides, roller 2 and roller is installed automatically, is connected connecting rod 6 by rotating shaft 4, rotating shaft 5 between lifting arm 1 and the roller 2; Connecting rod 6 is connected its sidewall with door body 8 by connecting pin 7; Connecting pin 7 tops of door body sidewall are provided with the block 9 of protrusion; The lower end of groove steel rail 3 also is provided with limited block 10.The protrusion height of block 9 and limited block 10 is corresponding with connecting rod 6 positions.
The utility model is four connecting rods and utilizes the gravity of door body to compress automatically and seal.When fire door rose, under the effect, connecting rod 67 rotated around the shaft in the F of elevator lifting force and fire door gravity, fire door 8 is vertically pushed away sealing surface 11 back to connecting rods 6 run into block 9 back fire doors 8 and just begin rising; When fire door descends, after the roller 2 of lower end is run into limited block 10, rotate, vertically push fire door to the sealing surface compact sealing strip at fire door gravity effect lower link 6.
The utility model has overcome the shortcoming of prior art, because good sealing effect, and do not need to consume external energy, thus good dual energy-efficient performance had.This kind mechanism is specially adapted to the sealing that compresses of big-and-middle-sized fire door.
Claims (2)
1, fire door compresses sealing mechanism automatically, comprises the groove steel rail (3) of being located at a lifting arm of body both sides (1), roller (2) and roller being installed, and it is characterized in that being connected connecting rod (6) by rotating shaft (4,5) between lifting arm (1) and the roller (2); Connecting rod (6) is connected its sidewall with door body (8) by connecting pin (7); Connecting pin (7) top of door body sidewall is provided with block (9); The lower end of groove steel rail (3) also is provided with limited block (10).
