The infrared preheating device of glass fibre filter paper
Technical field
The utility model belongs to glass fibre filter paper preheating field, is specifically related to the infrared preheating device of a kind of glass fibre filter paper.
Background technology
Glass fibre air filter paper uses very extensive, along with socioeconomic fast development, the requirement of the toilets such as medicine, bioscience, integrated circuit, aseptic operating room is more and more higher, to the intensity of air filter paper and processability, require also more and more higher, and at present can only be by add modification strengthening agent in glass fibre air filter paper the inside, because reinforcing agent needs certain solidification temperature, if enhanced productivity to improve baking temperature, easily produce sticky net, sticky cylinder phenomenon, thereby production efficiency is restricted.Therefore, before oven dry, should improve the temperature of glass fibre air filter paper, accelerate the self-crosslinking of reinforcing agent, so both solve sticky cylinder, sticky net problem, also improve production efficiency.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of infrared preheating apparatus for glass fibre air filter paper, for improve the temperature of glass fibre air filter paper before oven dry, accelerates the self-crosslinking of reinforcing agent.
The purpose of this utility model is achieved through the following technical solutions:
The infrared preheating device of a kind of glass fibre filter paper, comprise heating cabinet and circulating fan, in described heating cabinet, be provided with filter paper carrying roller, the upper and lower end of described filter paper carrying roller is also provided with heating tube and wind distributing hole plate, air inlet pipeline and air return pipeline are set between described circulating fan and heating cabinet, described circulating fan is delivered to wind distributing hole plate by air inlet pipeline by wind, wind heats from blowing to filter paper between heating tube by wind distributing hole plate, and described air return pipeline is also provided with return air suction inlet in heating cabinet.
Further, described heating tube is for adopting the quartz heating-pipe of Electric heating.
Further, the air return method of described air return pipeline is side return air.
Further, described heating cabinet is also provided with dehumidifying pipelines.
Further, described return air suction inlet place is also provided with screen pack.
Further, the inwall of described heating cabinet is also provided with heat-insulation layer.
The beneficial effects of the utility model are: the utility model is by carrying out prebake conditions preheating to glass fibre air filter paper, can make the moisture of glass fibre filter paper reduce 20-30%, accelerate the self-crosslinking of reinforcing agent, thereby enhance productivity, solve the sticky cylinder of reinforcing agent, sticky net problem when drying; In addition, infrared vibration heating from inside to outside, is beneficial to the maintenance of the fluffy tissue of glass, thereby does not affect filter efficiency and keep higher air permeability.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating below, or can from practice of the present utility model, be instructed.Target of the present utility model and other advantages can be realized and be obtained by description below.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is the utility model structural representation.
The specific embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment is only for the utility model is described, rather than in order to limit protection domain of the present utility model.
As shown in the figure, the infrared preheating device of a kind of glass fibre filter paper, comprise heating cabinet 9 and circulating fan 1, in described heating cabinet, be provided with filter paper carrying roller 5, the upper and lower end of described filter paper carrying roller is also provided with heating tube 4 and wind distributing hole plate 3, air inlet pipeline 2 and air return pipeline 7 are set between described circulating fan and heating cabinet, described circulating fan is delivered to wind distributing hole plate by air inlet pipeline by wind, wind heats from blowing to filter paper between heating tube by wind distributing hole plate, and described air return pipeline is also provided with return air suction inlet 6 in heating cabinet.
In the present embodiment, the l Water Paper page for preparing the glass fibre air filter paper 10 that contains reinforcing agent is delivered to carrying roller 5 guipure above, its guipure speed and l Water Paper page shaping speed synchronous transport, circulating fan is delivered to wind distributing hole plate by intake stack by wind, wind heats by blowing to product between the quartz ampoule of heating by wind distributing hole plate, thereby quartz ampoule produces stronger thermo-effect of infrared radiation by thermal radiation product is carried out to high-frequency heating from inside to outside therebetween, moisture becomes water vapour by this process from inside to outside and is discharged by the dehumidifying pipelines at the top of baking oven, in this process, the self-crosslinking speed of reinforcing agent is accelerated rapidly therebetween, then waste heat is recovered to circulating fan circulating-heating again by the backwind tube of circulating fan from the both sides of baking oven.Then preheating and drying to the page of water content 40% being delivered to hot air drier is dried, owing to evaporating most of moisture, the crosslinked 65-70% of reinforcing agent left and right, after baking oven only need a small amount of heat energy to get final product dry products, and reinforcing agent strengthens effect and also greatly promotes.
In the present embodiment, described heating tube is for adopting the quartz heating-pipe of Electric heating, and described quartz heating-pipe can produce the effect of infrared heating, and wherein quartz ampoule is totally 36, heating power 108KW.
In the present embodiment, the air return method of described air return pipeline is side return air; In the present embodiment, air-supply adopts the mode of air-supply up and down, and return air adopts the mode of side return air, and recirculating air flow smoothness is smooth and heating effect is good.
In the present embodiment, described heating cabinet is also provided with dehumidifying pipelines 8, and described dehumidifying pipelines 8 can be by useless wet and dust discharge.
In the present embodiment, described return air suction inlet place is also provided with screen pack, and described screen pack is stainless steel 40 order screen packs.
In the present embodiment, the inwall of described heating cabinet is also provided with heat-insulation layer; The thickness of described heat-insulation layer is 150mm.
Filtering material prepared by the present embodiment and traditional drying comparison, testing result is as shown in the table:
