Abstract
The utility model discloses a kind of graphite reactor top improvement mechanism, comprise upper cover plate and upper cover, described upper cover plate is located at the top of described upper cover, described upper cover plate is fixedly connected with by screw rod with upper cover, described screw rod is through described upper cover plate and upper cover, described screw tip is provided with stay-bolt, is provided with stop up the head bottom described screw rod.Described upper cover and stop up the head are graphite material, are fixedly connected with between upper cover plate and upper cover by screw rod, are regulated fixing by stay-bolt.The utility model by fixing by screw rod between upper cover plate and upper cover, thus graphite seal head is fixed by the active force of pull bar and upper cover plate, increase the intensity of graphite seal head, namely upper cover plate is for the intensity of the reinforcement of graphite seal head, reduce the thickness of graphite seal head, relatively ensure that dipping thickness.
Description
Technical field
The utility model relates to a kind of graphite reactor structure, is specifically related to a kind of top structure-improved of large-scale graphite reactor.
Background technology
Graphite reactor large-scale is at present under high vacuum state, because upper cover diameter is excessive, and upper cover needs arrange the dozens of interfaces such as manhole, charging hole, observation panel, gas outlet, mouth for subsequent use, and mechanical seal, stirring motor are installed, now the calculated thickness of end socket needs to be far longer than 200mm, and at dipping process, dipping thickness limit value is only 30mm, even if increase thickness, be also buried hidden danger in a device.
Utility model content
Utility model object: the purpose of this utility model is to solve deficiency of the prior art, provides a kind of and increases the intensity of graphite seal head, reduces the thickness of graphite seal head, relatively ensure that the graphite reactor top improvement mechanism of dipping thickness.
Technical scheme: a kind of graphite reactor top improvement mechanism described in the utility model, comprise upper cover plate and upper cover, described upper cover plate is located at the top of described upper cover, described upper cover plate is fixedly connected with by screw rod with upper cover, described screw rod is through described upper cover plate and upper cover, described screw tip is provided with stay-bolt, is provided with stop up the head bottom described screw rod.
As optimization, described upper cover is graphite seal head, and the diameter of described upper cover is greater than 2 meters.
As optimization, described screw rod is carbon steel screw rod.
As optimization, the bottom of described screw rod is T-shape structure, and T-shape body structure surface is enclosed with stop up the head.
As optimization, described stop up the head is graphite plug.
As optimization, the thickness of described upper cover plate is 70-90mm, and the thickness of described upper cover is less than 200mm.
Beneficial effect: the utility model by fixing by screw rod between upper cover plate and upper cover, thus graphite seal head is fixed by the active force of pull bar and upper cover plate, increase the intensity of graphite seal head, namely upper cover plate is for the intensity of the reinforcement of graphite seal head, reduce the thickness of graphite seal head, relatively ensure that dipping thickness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of graphite reactor top improvement mechanism as shown in Figure 1, comprise upper cover plate 1 and upper cover 2, described upper cover plate 1 is located at the top of described upper cover 2, described upper cover plate 1 is fixedly connected with by screw rod 3 with upper cover 2, described screw rod 3 is through described upper cover plate 1 and upper cover 2, described screw rod 3 top is provided with stay-bolt 4, is provided with stop up the head 5 bottom described screw rod 3.
As the further optimization of technique scheme, described upper cover 2 is graphite seal head, and the diameter of described upper cover 2 is greater than 2 meters.Described screw rod 3 is carbon steel screw rod, and the bottom of described screw rod 3 is T-shape structure, and T-shape body structure surface is enclosed with stop up the head 5, and described stop up the head 5 is graphite plug.The thickness of described upper cover plate 1 is 70-90mm, and the thickness of described upper cover 2 is less than 200mm, although therefore upper cover plate has strengthening action to upper cover, its weight is also forming very large pressure to upper cover virtually.With pull bar, the first dipping thickness that can ensure upper cover, second can play a pull-up active force to upper cover, alleviate the pressure that upper cover gravity brings, and equipment is in vacuum process, the gravity effect of end socket self.
The utility model by fixing by screw rod between upper cover plate and upper cover, thus graphite seal head is fixed by the active force of pull bar and upper cover plate, increase the intensity of graphite seal head, namely upper cover plate is for the intensity of the reinforcement of graphite seal head, reduce the thickness of graphite seal head, relatively ensure that dipping thickness.
