Abstract
The roller shaft end heat insulating and sealing device for float glass annealing kiln includes aluminum silicate fiber felts on two sides of the annealing kiln sandwich, and at least two layers of aluminum silicate fiber tapetum between aluminum silicate fiber felts to contact the roller shaft without gap. Both the aluminum silicate fiber felt and the aluminum silicate fiber tapetum are standard products. The present invention has greatly raised sealing performance.
Description
Technical field:
The present invention relates to a kind of float glass lehr roller axle end sealing device and method.
Background technology:
Existing float glass lehr roller axle end place sealed structure all is to adopt the both sides calcium silicate board with microporous in two interior side shields of annealing furnace body, and therebetween is established alumina silicate fiber felt, and calcium silicate board with microporous and alumina silicate fiber felt and lehr roller leave certain running clearance.Because calcium silicate board with microporous and alumina silicate fiber felt hardness are big, the inevitable gap that produces between calcium silicate board with microporous and the alumina silicate fiber felt, therefore the sealing of this material and structure is poor, and the envrionment temperature of float glass lehr has been produced very adverse influence.Extensively retrieve at the problems referred to above, case is put in the solution that still finds no effect.
Summary of the invention
Purpose of the present invention is sought out a kind of replacement material and sealed structure exactly, thereby makes sealed structure produce the gap greatly to cause the relatively poor shortcoming of stopping property to solve hardness that existing sealing material exists.
To achieve these goals, the present invention has taked following technical scheme:
A kind of float glass lehr roller axle end sealing device, it comprises annealing furnace body and the roller axle of passing the kiln body, be provided with heat insulation seal device in the interlayer of kiln body, it is characterized in that described heat insulation seal device by the alumina silicate fiber felt that is arranged on annealing furnace interlayer body both sides, and form at the alumina silicate fibre blanket more than 2 layers that both sides alumina silicate fiber felt therebetween is established.Each alumina silicate fiber felt is provided with the hole of matching with roller axle, and alumina silicate fibre blanket then is gapless with the roller axle surface and contacts.Described alumina silicate fiber felt and alumina silicate fibre blanket all are known standard prods, and they are processed to thread, and its main component is SiO2+Al2O3, and the density of alumina silicate fiber felt and alumina silicate fibre blanket is respectively 190kg/m
2And 128kg/m
2, their thermal conductivity is all lower, generally uses below 900 ℃, and alumina silicate fiber felt is harder, and it is arranged at annealing furnace body both sides, and is provided with the axis hole in gap between it and the roller axle.Alumina silicate fibre blanket is softer, and it is located between the alumina silicate fiber felt in case subside, because the flexibility of alumina silicate fibre blanket, there is not running clearance between it and the roller axle, also very close to each other between the alumina silicate fibre blanket, therefore, they cooperate use can play very good sealing function.
The invention has the advantages that: adopted to press from both sides between alumina silicate fiber felt and established alumina silicate fibre blanket, replaced the alumina silicate fiber felt that folder is established between original calcium silicate board with microporous, it can tightly be attached on the axle head head, eliminated the gap between spindle nose, also eliminated simultaneously the gap between the alumina silicate fibre blanket, the harder alumina silicate fiber felt in the outside has prevented that the alumina silicate fibre blanket that inboard folder is established from subsiding, make the float glass lehr roller axle end stopping property greatly improve, satisfied the insulation requirement of temperature curve in the float glass lehr.
For the present invention is described in further detail, following accompanying drawing provides a most preferred embodiment of the present invention.
Description of drawings:
Fig. 1 is a front view of the present invention;
Embodiment:
As shown in Figure 1, the float glass lehr body is made up of the outer side shield 1 of two-layer steel, both sides are provided with a harder alumina silicate fiber felt 2 respectively in its interlayer, be folded with 4 layers of alumina silicate fibre blanket 3 between the alumina silicate fiber felt 2, each alumina silicate fiber felt 2 is provided with the hole 5 of matching with roller axle, and alumina silicate fibre blanket then is gapless with the roller axle surface and contacts.
