Abstract

The invention relates to a method for tightly filling thermal-insulation cotton blanket into an annealing kiln. The method comprises the following steps: according to the shape of an annealing kiln, cutting a cotton blanket into a shape suitable for filling; laminating a plurality of layers of cut thermal-insulation cotton blankets together to satisfy the filling requirement; placing a press rod on the plurality of layers of thermal-insulation cotton blankets; binding laminated thermal-insulation cotton blankets by a set of binding belts according to the cross section; placing the bound thermal-insulation cotton blankets into the filling space of the interlayer of the annealing kiln; unbinding all binding belts to make the thermal-insulation cotton blankets fully rebound so as to fill the filling space fully. The method has the advantages that after the thermal-insulation cotton blankets are bound, the cotton blankets can be placed into the filling space of the interlayer of an annealing kiln without rebounding, thus the filling density is higher, after the binding belts are removed, the space can be fulfilled by the rebounded thermal-insulation cotton blankets, the filling becomes more uniform, no special equipment is required, and the filling cost is low.

Description

A kind of annealing furnace dense packing effect insulation cotton blanket method

Technical field

The present invention relates to annealing furnace heat preservation technology field, particularly a kind of annealing furnace dense packing effect insulation cotton blanket method.

Background technology

In flat glass production process, need through operations such as proportioning raw materials, fusing, shaping, annealing, cuttings, finally can output sheet glass.Wherein in annealing operation, need anneal by set curve to plate glass belt with annealing furnace, in annealing process, some position needs insulation, some position needs cooling, at the insulation position of annealing furnace, found by long research, heat insulation effect can affect annealing effect, annealing effect then can affect glass quality, present stage adopts filling insulation cotton blanket in interlayer to make kiln body to be incubated, fill out the larger heat insulation effect of insulation cotton blanket density in interlayer better, therefore, more dense packing effect insulation cotton blanket can affect the inner quality of sheet glass.

On plate glass annealing furnace, the insulation cotton blanket used is the flocculent substance of aluminum silicate fiber material, light weight, high resilience, rug shape, in interlayer, need filling multilayer.When manufacturing annealing furnace, be by manual compression at present, fill insulation cotton blanket, its filling difficulty is large, and tamped density is also difficult to ensure.

At Chinese patent: patent name is the cotton preformer device of a kind of simple and easy moisturizing, the patent No. is in ZL201410345903.3, the one insulation cotton blanket compact machine provided, to realize the target of filling insulation cotton blanket in the interlayer of annealing furnace, this patent adopts in frame, arranges upper and lower roll body structure, gap between upper and lower roll body can regulate, thus after cotton blanket compacting will be incubated, then insert packing space.There is following shortcoming in this patent: one, after being compacted, and before putting into packing space, insulation cotton blanket meeting resilience, can reduce tamped density; Two, successively compacting, put into packing space, the insulation cotton blanket resilience of previously having put into can be larger, can reduce tamped density further; Three, need special machinery, filling cost can be increased.

Summary of the invention

The object of the invention is to be incubated cotton blanket resilience to solve in present stage annealing furnace and to reduce tamped density, need special filling machinery, increase shortcomings such as filling cost, and a kind of annealing furnace dense packing effect insulation cotton blanket method proposed.

To achieve these goals, present invention employs following technical scheme:

A kind of annealing furnace dense packing effect insulation cotton blanket method, is characterized in that comprising the following steps:

Step one, shape according to annealing furnace interlayer, be cut into insulation cotton blanket the shape needing to fill;

Step 2, cut out the multi-layer heat preserving cotton blanket after shaping and be stacked together described, with satisfied filling requirement;

Step 3, on the described multi-layer heat preserving cotton blanket stacked, be provided with depression bar;

Step 4, on the insulation cotton blanket stacked, bundle one group of strapping tape by cross section;

Step 5, the insulation cotton blanket bundled is put into the packing space of described annealing furnace interlayer;

Step 6, untie all strapping tape on insulation cotton blanket, make the abundant resilience of described insulation cotton blanket, with the packing space of full described annealing furnace interlayer.

On the basis of technique scheme, following further technical scheme can be had:

Lining bar is placed, to facilitate tying up of insulation cotton blanket below the described multi-layer heat preserving cotton blanket stacked.

When bundling insulation cotton blanket, the position of mobile described depression bar and lining bar, to facilitate the binding of described strapping tape.

The invention has the advantages that: after method provided by the present invention is tied up insulation cotton blanket, can without the packing space putting into filling annealing furnace interlayer of resilience, tamped density can be made higher, after removal strapping tape, fill packing space by insulation cotton blanket material natural resiliency, can make that insulation cotton blanket is filled evenly, present method fill be incubated cotton blanket time, do not need special purpose device, filling cost is low.

Embodiment

For making the present invention clearly understand, describe in detail this device below in conjunction with accompanying drawing, specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.

As shown in Figure 1, a kind of annealing furnace dense packing effect insulation cotton blanket method provided by the invention, is characterized in that comprising the following steps:

Step one, shape according to annealing furnace interlayer, be cut into insulation cotton blanket 1 shape needing to fill.

Step 2, thickness according to annealing furnace interlayer, cut out the insulation cotton blanket 1 after shaping and the expectation number of plies be stacked together described, with satisfied filling requirement.

Step 3, described in place lining bar 2 below the insulation cotton blanket 1 that stacks, to facilitate tying up of insulation cotton blanket 1, described lining bar uses common rod-like structure.

Step 4, on the described multi-layer heat preserving cotton blanket 1 stacked, be provided with depression bar 3, depression bar 3 and described lining bar 2 are arranged in same perpendicular, and described depression bar 3 presses down with compacting insulation cotton blanket 1, and improve tamped density, depression bar 3 used uses common lever.

Step 5, on the insulation cotton blanket 1 stacked, bundle one group of strapping tape 4 by cross section, with strapping tape 4, insulation cotton blanket 1 is tied up by cross section, to prevent before filling, the insulation cotton blanket resilience of institute's compacting, when bundling strapping tape 4, described strapping tape 4 through the downside of insulation cotton blanket 1, to fix the two ends of strapping tape 4 near lining bar 2 by tying up knot 5 at the upper side of insulation cotton blanket 1, described in tie up knot 5 for prior art.After strapping tape 4 ligation is good, mobile described depression bar 3 and the position of lining bar 2 on insulation cotton blanket 1, to facilitate the binding of next strapping tape 4, until the insulation cotton blanket 1 of whole folded side is tied up completely by cross section, insulation cotton blanket 1 volume after tying up is little, conveniently put into annealing furnace Sandwich filling space, and strapping tape 4 used is rope class formation.

Step 6, the insulation cotton blanket 1 bundled is put into the packing space of described annealing furnace interlayer.

Step 7, untie and extract the strapping tape 4 of binding insulation cotton blanket 1 out one by one, make the fully resilience of described insulation cotton blanket 1, with the packing space of full described annealing furnace interlayer, the insulation cotton blanket 1 after resilience makes the even of annealing furnace Sandwich filling, high insulating effect.
