Abstract

The utility model discloses a kind of graphite reactor rabbling mechanism, comprise main shaft steel pipe, described main shaft outer surface of steel tube is provided with main shaft graphite-pipe, described main shaft steel pipe is connected with some symmetrically arranged paddles, and described paddle is the circular configuration be made up of paddle central shaft, paddle steel pipe and mixing center axle head plate; Described paddle outer surface of steel tube is provided with paddle graphite-pipe; paddle graphite plug is provided with outside described mixing center axle head plate; described paddle graphite-pipe and paddle graphite plug form square paddle graphite operator guards, are also provided with main shaft graphite plug bottom described main shaft steel pipe.The utility model is by improving original paddle, consider the linear expansion coefficient of linear expansion coefficient lower than steel part of graphite, steel part and graphite-structure are improved, thus solves the problem of the easy spalling of outsourcing graphite, thus extend the service life of product.

Description

A kind of graphite reactor rabbling mechanism
Technical field
The utility model relates to a kind of rabbling mechanism, is specifically related to a kind of rabbling mechanism be applied in large-scale graphite reactor.
Background technology
Rabbling mechanism is one of graphite reactor core component.General rabbling mechanism comprises main shaft and each shaft composition, and shaft outer surface is made (structure as shown in Figure 2) by graphite outside steel pipe.But because the linear expansion coefficient of graphite is lower than the linear expansion coefficient of steel part, under the effect of temperature, easily cause the generation of the phenomenons such as outsourcing graphite spalling, thus need the continuous shaft more renewed, thus reduce the service life of shaft, also reduce operating efficiency.
Utility model content
Utility model object: the purpose of this utility model is to solve deficiency of the prior art, provides the graphite reactor rabbling mechanism of a kind of reasonable in design, long service life.
Technical scheme: a kind of graphite reactor rabbling mechanism described in the utility model, comprise main shaft steel pipe, described main shaft outer surface of steel tube is provided with main shaft graphite-pipe, described main shaft steel pipe is connected with some symmetrically arranged paddles, and described paddle is the circular configuration be made up of paddle central shaft, paddle steel pipe and mixing center axle head plate; Described paddle outer surface of steel tube is provided with paddle graphite-pipe; paddle graphite plug is provided with outside described mixing center axle head plate; described paddle graphite-pipe and paddle graphite plug form square paddle graphite operator guards, are also provided with main shaft graphite plug bottom described main shaft steel pipe.
As optimization, outside described main shaft steel pipe, be also provided with mechanical seal sleeve pipe.
As optimization, the joint of described paddle graphite-pipe and described main shaft graphite-pipe is also provided with paddle graphite stiffening ring.
As optimization, between described paddle graphite stiffening ring and described main shaft graphite-pipe, be provided with gap.
As optimization, described paddle central shaft, paddle steel pipe are fixedly connected by welding with described main shaft steel pipe respectively.
Beneficial effect: the utility model is by improving original paddle, consider the linear expansion coefficient of linear expansion coefficient lower than steel part of graphite, steel part and graphite-structure are improved, thus solves the problem of the easy spalling of outsourcing graphite, thus extend the service life of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structural representation of the prior art.
Detailed description of the invention
A kind of graphite reactor rabbling mechanism as shown in Figure 1, comprise main shaft steel pipe 2, described main shaft steel pipe 2 outer surface is provided with main shaft graphite-pipe 3, described main shaft steel pipe 2 is connected with some symmetrically arranged paddles, and described paddle is the circular configuration be made up of paddle central shaft 5, paddle steel pipe 7 and mixing center axle head plate 8; Described paddle steel pipe 7 outer surface is provided with paddle graphite-pipe 6; paddle graphite plug 9 is provided with outside described mixing center axle head plate 8; described paddle graphite-pipe 6 and paddle graphite plug 9 form square paddle graphite operator guards, are also provided with main shaft graphite plug 10 bottom described main shaft steel pipe 2.
As the further optimization of technique scheme, outside described main shaft steel pipe 2, be also provided with mechanical seal sleeve pipe 1.Described paddle graphite-pipe 6 is also provided with paddle graphite stiffening ring 4 with the joint of described main shaft graphite-pipe 3.Be provided with gap between described paddle graphite stiffening ring 4 and described main shaft graphite-pipe 3, under state of temperature, give space, graphite expansion stationary point.Described paddle central shaft 5, paddle steel pipe 7 are fixedly connected by welding with described main shaft steel pipe 2 respectively.
Stirring structure schematic diagram of the prior art as shown in Figure 2.Existing structure is very simple, directly at steel pipe paddle outer layer covers one deck graphite, but because the linear expansion coefficient of graphite is lower than the linear expansion coefficient of steel part, under the effect of temperature, easily cause the generation of the phenomenons such as outsourcing graphite spalling, thus need the continuous shaft more renewed, thus reduce the service life of shaft, also reduce operating efficiency.
