Abstract
The invention discloses an anti-loose device for hearth and heat preservation used for a carbon fiber high temperature furnace, comprising a hearth, a heat preservation layer and a hearth casing which are arranged on the outside of the hearth successively. The compact degrees of the hearth casing and the heat preservation layer are adjusted by tightening devices which are circumferentially disposed on the hearth casing. The heat preservation layer is circumferentially added to the hearth of the high temperature furnace, and mounting holes are opened on the hearth casing of the high temperature furnace. The hearth having regulating function and heat preservation tightening devices are installed by the mounting holes. By adjusting the tightening devices, the compact degrees between the hearth casing and the heat preservation layer can be controlled to enable the backlashes to maintain between the heat preservation layer and the hearth casing. Therefore, the hearth casing and the heat preservation layer can be always maintained compactly, to maintain the air impermeability of the hearth and the heat preservation effect.
Description
Technical field
The present invention relates to a kind of carbon fiber high temperature furnace, relate in particular to the locking device of high temperature furnace used burner hearth of a kind of carbon fiber and insulation.
Background technology
The splicing construction that present high temperature furnace all adopts the graphite burner hearth to add heat-insulation layer carries out internal insulation; But under long-term high temperature action, graphite and insulation material can progressively be cavitated, along with the growth of service time; The structure of its burner hearth and insulation can be loose; The heat insulation effect of the air-tightness of burner hearth and heat-insulation layer will reduce like this, even burner hearth is caved in, and greatly reduces the service life of burner hearth.
Summary of the invention
The objective of the invention is to solve the problem of burner hearth air-tightness and heat insulation effect variation in the prior art, the locking device of high temperature furnace used burner hearth of a kind of carbon fiber and insulation is provided.
Technical scheme of the present invention is: the locking device of high temperature furnace used burner hearth of a kind of carbon fiber and insulation; Comprise burner hearth and be set in turn in burner hearth outside heat-insulation layer, stove outer covering; The compactness extent of said burner hearth and heat-insulation layer, the burner hearth that circumferentially is provided with through the stove outer covering tight device that bears down on one is regulated.
Leave the gap between said heat-insulation layer and the said stove outer covering.
Said burner hearth hold down gag is a helicitic texture, and said helicitic texture passes the circumferential installing hole that is provided with of stove outer covering and withstands said heat-insulation layer.
Said helicitic texture is symmetricly set in the wall of stove outer covering.
Said heat-insulation layer is a several layers.
Said burner hearth is the graphite burner hearth.
The locking device of high temperature furnace used burner hearth of a kind of carbon fiber of the present invention and insulation; Circumferentially add heat-insulation layer at the high temperature furnace burner hearth, and on the stove outer covering of high temperature furnace mounting holes, burner hearth and the insulation holding device with regulatory function is installed through installing hole; Can control the tightness between burner hearth and the heat-insulation layer through regulating this holding device; The gap is stayed between heat-insulation layer and the stove outer covering, thereby made burner hearth and heat-insulation layer remain densification, to keep burner hearth air-tightness and heat insulation effect.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Understand for technological means, technical characterictic, goal of the invention and the technique effect that the present invention is realized is easy to understand,, further set forth the present invention below in conjunction with concrete diagram.
As shown in Figure 1; Locking device for high temperature furnace used burner hearth of a kind of carbon fiber of the present invention and insulation; The stove outer covering 2 that comprises graphite burner hearth 1 and be arranged at burner hearth 1 outside; Be close in the periphery of burner hearth 1 and be provided with heat-insulation layer 3, burner hearths and tight device 4 of insulation roof pressure and said burner hearth 1 adjustable position that heat-insulation layer 3 circumferentially is provided with through stove outer covering 2 make heat-insulation layer 3 and closely subsides mutually of burner hearth 1 through regulating burner hearth hold down gag 4.
Heat-insulation layer 3 is a several layers in the present invention, can eject certain clearance 5 between heat-insulation layer 3 and the stove outer covering 2; Burner hearth hold down gag 4 adopts several helicitic textures, stove outer covering 2 circumferentially be provided with the installing hole that is used to install helicitic texture, through installing hole helicitic texture is installed and is realized regulatory function.
The locking device of high temperature furnace used burner hearth of a kind of carbon fiber of the present invention and insulation; Circumferentially add heat-insulation layer 3 at high temperature furnace burner hearth 1; And on the stove outer covering 2 of high temperature furnace mounting holes; Through installing hole the burner hearth hold down gag 4 with regulatory function is installed, can be controlled the tightness between burner hearth 1 and the heat-insulation layer 3, the gap is stayed between heat-insulation layer 3 and the stove outer covering 2 through regulating this burner hearth hold down gag 4; Thereby make burner hearth 1 and heat-insulation layer 3 remain densification, to keep the air-tightness and the heat insulation effect of burner hearth 1.
Being merely preferred embodiment of the present invention in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of claim of the present invention change and modification, all should belong to technological category of the present invention.
