Description

Hot-blast stove and tunnel air-heating evaporating bellows

The utility model relates to a kind of heating and evaporation drying set composite with gas work sanction thermal medium, is mainly used in the compound of vinylon cloth and brown paper.

The packaging bag of making after dimension/paper is compound is mainly used in the packing of cement and other flour, and it is compared with general paper bag for cement, can save 3/4ths paper consumption, and intensity has increase again, and the breakage in the transportation also greatly reduces, and cost is also low.Yet, can only select water base adhesive slimy milk liquid cheaply for use because the product price of this kind packaging bag is low.The water content of the gluing emulsion of this kind reaches 92%, and the glue-spread of compound tense reaches every square metre 80 gram in addition, thereby the water evaporates amount of compound tense is big, and energy consumption is higher.

In existing thermal source generating means and dry vaporising device, if adopt boiler and drying cylinder evaporation equipment,, construction period length big because of its investment is felt difficulty; Use electric heating evaporation, then huge infeasible again because of power consumption.

Task of the present utility model provides a kind of heating evaporation dry composite device, and this device is the moisture content of evaporation drying dimension/paper compound tense effectively, and device structure is comparatively simple, cost is lower.

The utility model is made up of following technical scheme:

Thermal source generating means and dry vaporising device in this device have adopted hot-blast stove and evaporation tank respectively.Air is pressed into pipeline by air blast and sends hot-blast stove to.Hot-blast stove is vertically installed, and the latter half of stove is the combustion chamber, and top of combustion chamber is one to have the refractory ceramics notch board of aperture.The first half of stove then from bottom to top vertical array some double helix shape gas water backs, furnace roof is a throat.Other has pipeline to arrange along the stove periphery of inner wall from the bottom screw around the top to blast furnace, constitutes preheating pipe.The air that enters hot-blast stove successively becomes hot gas and exports evaporation tank to through preheating pipe, water back.Be provided with upper and lower heating clamber in the evaporation tank, have pipeline to communicate between two Room, form substantially parallel passage between the upper and lower baking deckle board of these two heating clambers, dimension/paper composites toasts drying from this passage process.Also be shaped on some apertures on the last baking deckle board, hot gas can spray from these apertures after entering heating clamber, to improve evaporation effect.In addition, this device also has some tractions, applying glue and speed and temp regulating controlling organization.

Further specify below in conjunction with embodiment shown in the drawings:

Fig. 1 is the general structure schematic diagram of this device.

Fig. 2 is a hot-blast stove internal structure schematic diagram.

Fig. 3 be among Fig. 2 the A-A position to view.

Fig. 4 is a dimension/paper compound tense course of work schematic diagram.

As Fig. 1, shown in Figure 4, this device comprises hot-blast stove, evaporation tank and some traction applying glues and speed and temp regulating mechanism.Air blast 1 starts, and orders about air and enters hot-blast stove heating through piping, becomes hot gas afterwards and enters evaporation tank from pipeline 8 and dimension/paper material is carried out drying evaporate.The internal structure of said hot-blast stove can be referring to Fig. 2.This hot-blast stove is vertically upright, and the Lower Half of stove is combustion chamber 10, and the first half is a water back.These pipelines are made spirality, and vertically are installed in the stove, and preheating pipe 5 also is installed around the stove inwall.In the present embodiment, the annexation between each pipeline is: a minimum end interface of preheating pipe joins in blower conduits and the hot-blast stove; The economizer bank road junction on stove top is by interface and several (among the figure being 6) water backs 7 that circumferentially distribute join (can be clear that among Fig. 3); A minimum end of these pipelines 7 joins with the king bolt water back 6 of stove central authorities again; One end pipeline opening of the topmost of pipeline 6 is joined with pipeline 8 again.Good for being incubated, the furnace wall has also adopted alumina silicate fibre to make heat-insulation layer 4.

For raising adds thermal effect, increase the service life, also at the foraminate refractory ceramics notch board 3 of the top of combustion chamber mounting strap, combustion flame and water back are kept apart to slow down the ablation of water back in the present embodiment.

The structure of evaporation tank can by among Fig. 1, Fig. 4 as can be known.Be provided with two heating clambers in the case, by heat-insulation layer 12,17 insulations.Keeping suitable spacing forming a baking channel between these two heating clambers, dimension/paper material from this passage through toasting drying.Baking deckle board 13 in the following heating clamber 16 and the baking deckle board 14 in the last heating clamber 15 are made by metal face to face.In addition, be shaped on some apertures on the baking deckle board 14; Communicate because of pipeline 24 is housed again between two heating clambers, the high hot-air that enters in the evaporation tank can be sprayed from said aperture at last, accelerate the rate of drying of dimension/paper material.

The course of work of the present utility model is as follows:

Dump burning in the Combustion of Hot Air Furnace chamber 10, the water back 7,5 in the oven.Air blast 1 orders about air and enters pipeline 5 from the hot-blast stove bottom, and gas moves to top along spiral pipeline shape, absorbs the heat energy of hot-blast stove inwall.Flow into inboard 6 double helix shape water backs 7 afterwards at pipeline 5 tops.Gas is operation along spirality pipe toward the lower end, continues heat exchange; Lower end at 6 double helix shape pipelines flows into center king bolt shape pipeline 6, and after further heating improved thermal capacity, hot gas transferred to the tunnel type evaporation tank by pipeline 8.Gas is introduced into heated baking deckle board 13 in the following heating clamber 16 of evaporation tank, enter heating clamber 15 heated baking deckle boards 14 by pipeline 24 again, the moisture content of evaporation dimension/paper material, go out the aperture from deckle board 14 at last, winding-up dimension/paper material, improve evaporation tank thermal capacity, and water vapour is discharged evaporation tank, accelerate evaporation drying speed.

On the other hand, driven by motor cylinder 11 batches dry dimension/paper composites; Composite roller 18 and 23 drags and compound vinylon cloth 21 and brown paper 22 again by driven by motor.In addition, also have in the diagram: adhesive cylinder 20, last glue cylinder 19.

Temperature indicator 9 and volume damper 2 are used to control the temperature of hot gas.Regulate the big I of intake and change hot blast temperature, combined temp generally is advisable between 140 degree at 130 degree.

Dimension/paper recombination velocity is made step-less adjustment by buncher, and the composite drying degree is guaranteed by above-mentioned two kinds of control systems.

Obviously, this installs than boiler and drying cylinder evaporation equipment, and is much simple in structure, and investment and cost are all much lower.
