Background
The utility model belongs to all centralized vertical heat treatment furnaces, the treatment time is up to 6 hours, the constant temperature is required to be within +/-5 ℃ in the period, the temperature of a large-scale treatment furnace is quickly volatilized, the temperature is required to be immediately increased when being reduced, otherwise, the quality of a treated product is unstable, and the unstable reason is that the temperature is quickly reduced and the sealing property of a furnace door is poor. Generally, the bottom of the vertical furnace is provided with a water tank, the upper part of the vertical furnace is provided with a heat treatment furnace, the middle separation furnace cover is only closed by pushing a movable door through a side pushing cylinder due to the topographic relation, and the bottom of the vertical furnace is provided with a guide rail inward pressing structure. When the heat treatment temperature is high, the pressure is increased, the airtight effect is quite poor as the pressure pushes the airtight door out, the energy is wasted, and the product quality is unstable. Aiming at the problems, the sealing structure scheme is designed.

The utility model improves the problems, namely the technical problem to be solved by the utility model is that the pressure of the existing Chinese vertical heat treatment furnace wastes energy for the airtight door top.
The specific embodiment of the utility model is as follows: reinforced self-sealing furnace cover comprises a support located between a furnace mouth of a heat treatment furnace and a cooling water tank, a track is transversely fixed on the support, a lower air-sealing cover is arranged on the track in a sliding fit mode, the upper portion of the lower air-sealing cover is hinged to an upper air-sealing cover through a connecting rod, and a stop block capable of blocking the upper air-sealing cover to move is fixed on the side of the furnace mouth of the heat treatment furnace.
Furthermore, the connecting rod sets up in the slant, and the connecting rod both ends are connected with last airtight lid and lower airtight lid are articulated respectively, the connecting rod is closer to the dog with the hinged end of last airtight lid than the connecting rod with the hinged end of lower airtight lid.
Furthermore, the lower part of the lower airtight cover is hinged with a guide wheel which can be in sliding fit with the guide rail.
Furthermore, a refractory fiber block is fixed on the top of the upper airtight block.
Further, the connecting rods are arranged in parallel.
Furthermore, the side part of the lower airtight cover is fixedly connected with the telescopic end of a driving device, and the driving device is an air cylinder or a hydraulic cylinder.
Compared with the prior art, the utility model has the following beneficial effects: the utility model realizes the adjustment of the pressing force by utilizing the rotatable structure of the upper airtight cover and the lower airtight cover, improves the sealing performance of the furnace door and reduces the energy consumption.

In the figure: 10-heat treatment furnace, 20-cooling water tank, 30-bracket, 40-rail, 110-lower airtight cover, 120-upper airtight cover, 130-connecting rod, 50-stop, 40-rail, 410-guide wheel, 60-refractory fiber block and 70-hydraulic cylinder.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, the reinforced self-sealing furnace cover comprises a support 30 located between a furnace mouth of a heat treatment furnace 10 and a cooling water pool 20, a rail 40 is transversely fixed on the support, a lower sealing cover 110 is slidably matched on the rail 40, the upper part of the lower sealing cover is hinged to an upper sealing cover 120 through a connecting rod 130, and a stop block 50 capable of blocking the upper sealing cover to move is fixed on the side of the furnace mouth of the heat treatment furnace.
In this embodiment, in the initial state, the connecting rod 130 is disposed obliquely, and the hinged end of the connecting rod 130 and the upper airtight cover 120 is closer to the stopper 50 than the hinged end of the connecting rod and the lower airtight cover.
In this embodiment, the stop block 50 is located beside the furnace mouth and is higher than the top airtight cover 120.
In this embodiment, the lower portion of the lower airtight cover is hinged to a guide wheel 410 capable of slidably engaging with the guide rail, so as to facilitate the movement of the lower airtight cover and the upper airtight cover 120 on the rail 40.
In this embodiment, the connecting rods 130 are arranged in parallel.
In one embodiment of the utility model, a refractory fiber block 60 is fixed on top of the upper airtight block.
In this embodiment, the driving device is a hydraulic cylinder 70, and the telescopic end of the driving device is fixedly connected with the side portion of the lower airtight cover.
When the furnace door sealing device works, the driving device acts to push the lower airtight cover 110 towards the direction of the stop block 50, the lower airtight cover 110 is pushed to move forwards, the lower airtight cover 110 is hinged with the two sides of the upper airtight cover 120 through a pair of connecting rods, the lower airtight cover 110 and the upper airtight cover 120 move synchronously, the upper airtight cover 120 contacts with the stop block 50 in the moving process and stops moving, the position is the position of the furnace opening of the heat treatment furnace and can seal the furnace opening, after the upper airtight cover 120 stops moving, the lower airtight cover 110 moves continuously, at the moment, the connecting rods swing from the oblique position to jack the upper airtight cover 120 upwards, and the upper airtight cover 120 and the refractory fiber block 60 tightly press the furnace door. Thus, the pressing force directions are different, so that the high-temperature pressure cannot push the oven door away.
The improvement can be adapted to different large heat treatment furnaces, the heat treatment furnaces cannot leak due to the pressure of hot air, the temperature is not well controlled, and the product quality is more stable.
If the utility model discloses or relates to parts or structures which are fixedly connected to each other, the fixedly connected parts can be understood as follows, unless otherwise stated: a detachable fixed connection (for example using bolts or screws) is also understood as: non-detachable fixed connections (e.g. riveting, welding), but of course, fixed connections to each other may also be replaced by one-piece structures (e.g. manufactured integrally using a casting process) (unless it is obviously impossible to use an integral forming process).
In addition, terms used in any technical solutions disclosed in the present invention to indicate positional relationships or shapes include approximate, similar or approximate states or shapes unless otherwise stated.
Any part provided by the utility model can be assembled by a plurality of independent components or can be manufactured by an integral forming process.
Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present invention and not to limit the same; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the utility model or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the utility model as defined by the appended claims.
