Abstract
The utility model discloses an atmosphere protection furnace gate apparatus including a door plate arranged at the doorway of a cabin body, a guide rail mechanism is arranged between the door plate and the cabin body to guide the door plate to move up and down, the door plate is driven by a driving mechanism arranged at the upper part of the cabin body, and the door plate and the driving mechanism are connected through a parallel four-bar linkage. Because the connection part of the cylinder or the hydraulic cylinder of the door plate adopts the parallel four-bar linkage, the door plate is free of obvious shaking and collision, and is impossible to generate sparks to cause explosion while moving up and down.
Description
Technical field
The utility model relates to kiln, relates in particular to the kiln gate.
Background technology
The valve system of kiln is moved up and down by cylinder or hydraulic cylinder drive door-plate in the prior art, and door was opened when door-plate moved upward, and saggar passes through; Door was closed when door-plate moved downward, thereby cut off the gas flow of door-plate both sides (kiln is inside and outside).Yet there is following defective in this structure:
When 1, door-plate moved up and down, door-plate rolling momentum was big, bumps easily, produces spark, and this situation is breakneck in the hydrogen shield stove, very easily sets off an explosion.
When 2, door-plate moved up and down, the sealing strip on warehouse and the door-plate produces friction, and was very big to the infringement of sealing strip, is prone to cause defectives such as poor sealing.
The utility model content
The utility model technical problem to be solved just provides a kind of atmosphere protection tweel device, the door-plate motion stabilization, and security is higher.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: atmosphere protection tweel device; Comprise the door-plate of being located at the warehouse doorway; It is characterized in that: be provided with guide rail mechanism guiding door-plate between said door-plate and warehouse and move up and down, door-plate is by the drive mechanism of being located at warehouse top, adopts parallel four-bar linkage to connect between said door-plate and driving mechanism.
As preferably, said guide rail mechanism comprises the guide rail of being located at the left and right sides, warehouse doorway, and said door-plate left and right sides upper and lower side is respectively equipped with a roller, and roller cooperates with guide rail.
As preferably, said roller is resin or rubber structure.
As preferably, said driving mechanism is cylinder or hydraulic cylinder.
As preferably, said door-plate top is provided with a lance, and top, said warehouse doorway is provided with the one stroke switch, and lance is used to trigger travel switch, and travel switch control driving mechanism opens and closes.
Parallel four-bar linkage is adopted in the connection place of the utility model cylinder or hydraulic cylinder and door-plate, and in the both sides of door-plate mounting guide rail, simultaneously the roller on the door-plate adopt high temperature resistant, resistance to wear, corrosion resistant resin or elastomeric material.Its beneficial effect is:
When 1, door-plate moves up and down, do not have and obviously rock, can not bump, more can not produce spark and set off an explosion.
When 2, door-plate moved up and down, sealing strip on warehouse and the door-plate kept certain distance, can friction sealed.
3, the roller of door-plate adopts resin or elastomeric material, and frictional heating is low during rolling, and no-spark produces.
4, door-plate cuts out the back good seal performance, has effectively prevented the convection current of door-plate both sides gases.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described:
Fig. 1 is the utility model structural representation;
Fig. 2 be among Fig. 1 A-A to sketch map.
The specific embodiment
Specify the utility model atmosphere protection tweel device in conjunction with Fig. 1 and Fig. 2; Comprise the door-plate 4 of being located at warehouse 1 doorway; Being provided with guide rail mechanism guiding door-plate between said door-plate and warehouse moves up and down; Door-plate is driven by the driving mechanism of being located at warehouse top 11, adopts parallel four-bar linkage 5 to connect between said door-plate and driving mechanism.Said guide rail mechanism comprises the guide rail 6 of being located at the left and right sides, warehouse doorway, and said door-plate left and right sides upper and lower side is respectively equipped with a roller 7, and roller cooperates with guide rail.Roller is located on the roller shaft 8.Said roller is resin or rubber structure.Said driving mechanism is cylinder or hydraulic cylinder.Said door-plate top is provided with a lance 9, and top, said warehouse doorway is provided with one stroke switch 10, and lance is used to trigger travel switch, and travel switch control driving mechanism opens and closes.Said warehouse doorway is provided with sealing strip 3.
The warehouse top is located in displacement chamber 2, and the displacement chamber is another space corresponding with warehouse, is a sealed space that takes up door and switching mechanism thereof.Effect be each indoor gas is replaced as when opening and closing door with storehouse (stove) in gas identical.To guarantee that the interior atmosphere in storehouse (stove) does not change because of opening and closing door.
Door-plate left and right sides upper and lower side respectively is provided with a hinge and forms parallel four-bar linkage, cylinder or hydraulic cylinder knee-action.
