Description
Technical field
The utility model relates to Muffle furnace firing equipment technical field, belongs to the muffle furnace stove gate device that a kind of crucible type Muffle furnace uses especially.
Background technology
Muffle furnace is applied comparatively wide in the test of coal-quality test, coal analysis, when " volatile matter " of coal measures, specifies: Muffle furnace is heated to about 920 DEG C in advance in " GB/T 212-2008 " 5.3.2.Open fire door, rapidly the tripod being placed with crucible is sent into flat-temperature zone, close upper furnace door immediately and timing, accurately heat 7min.After crucible and tripod are put into, require that furnace temperature returns in 3min (900 ± 10) DEG C, after this remain on (900 ± 10) DEG C, otherwise this time test calcellation.As can be seen from regulation, this detection method is very high to the requirement of rising again.Muffle furnace open door after heat loss be exceedingly fast, operating personnel be generally difficult to arrive this requirement.
Summary of the invention
Namely the purpose of this utility model is to provide a kind of muffle furnace stove gate device, convenient to reach switch, reduces the object of Muffle furnace heat loss.
Muffle furnace stove gate device provided by the utility model, have and be opened in door body frame on Muffle furnace door and convenient door, it is characterized in that, door body frame is provided with the chute guide rail that also can run through body frame vertical with door body frame, convenient door is arranged on chute guide rail, and with door body frame close fit, be provided with tripod inside convenient door.
The utility model provides muffle furnace stove gate device, and convenient door can at chute slide on rails, can open and close fast, and convenient door and tripod link together, and while convenient door is opened, crucible also moves to outside Muffle furnace with tripod.Convenient door open area is relatively little, and the air-flow of drive is also less; Tripod moves to outside Muffle furnace with convenient door, decreases enabling, gets the time of crucible.Therefore, the utility model has the good effect scattered and disappeared of heat in the convenient and a large amount of minimizing Muffle furnace of switch.
Accompanying drawing explanation
Accompanying drawing part discloses the utility model specific embodiment, wherein,
Fig. 1, the utility model structural representation;
Fig. 2, the utility model inside structure schematic diagram;
Fig. 3, the utility model opening structural representation.
Detailed description of the invention
As shown in the figure, muffle furnace stove gate device provided by the utility model is arranged on Muffle furnace 2, has a body frame 1 and convenient door 2.Described convenient door is in block, and there is heat-insulation layer inner side, outside jug.Door body frame is provided with four chute guide rails 4 that also can run through body frame vertical with door body frame, convenient door is arranged on chute guide rail, be provided with tripod 5 inside convenient door, convenient door can at chute slide on rails, and while convenient door skids off, crucible also moves to outside Muffle furnace with tripod; When convenient door slips into, crucible also enters in Muffle furnace with tripod, door body frame is implemented shutoff airtight simultaneously.Because convenient door open area is relatively little, the air-flow of drive is also less, at utmost can reduce scattering and disappearing of furnace heat.
