Detailed description of the invention
below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature are easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made and more removed clear and definite defining.
consult Fig. 1; Fig. 1 has shown in prior art for clean the schematic diagram of the sprinkling equipment of dry net in the time shutting down; this equipment comprises spray bar; spray bar comprises stainless steel body 12; be located at the water inlet pipe 11 in stainless steel body 12 1 ends; and being positioned at the water discharge outlet 13 of stainless steel body 12 the other end, stainless steel body 12, by multiple stent support, is provided with multiple spray heads for dry net is cleaned on stainless steel body 12.This kind of sprinkling equipment needs paper machine to shut down in use, can waste a large amount of time.In addition, because drying part of paper making machine temperature is high, operating environment is severe, thereby the limitation of this kind of sprinkling equipment use is larger, is difficult to efficiently, use chronically.
consult Fig. 4 to Fig. 5, this two width figure has shown the schematic diagram of dry net cleaning device of the present utility model, wherein, this device comprises the frame 1 of playing a supporting role, in frame 1, be provided with the spray equipment 2 that can move left and right along frame 1, spray equipment 2 by motor 4 by chain drive to move along left and right directions in frame 1.Spray equipment 2 comprises nozzle assembly 3, consult Fig. 2, nozzle assembly 3 comprise with the air inlet 31 being connected for delivery of compressed-air actuated compressed air piping, with the feeding opening 32 being connected for delivery of the dry net clean-preserving agent pipeline of dry net clean-preserving agent, and the atomizer 33 being connected respectively with air inlet 31 and feeding opening 32, atomizer 33 is for dry online by being sprayed on after compressed air and dry net clean-preserving agent mixed aerosol, nozzle assembly 3 also comprises the control valve 34 that is arranged on feeding opening 32 places, and control valve 34 is for controlling into dose.Enter dose and also can regulate by stroke or the flow of the membrane pump M for dry net clean-preserving agent is provided, this control valve 34 can not will close to the very little dose that enters, otherwise is easy to cause the flexible pipe explosion of chemical feed pipe.
in the present embodiment, frame 1 is made up of left and right two parts, and the spray equipment 2 being respectively arranged with in two parts of frame in 2, two parts of spray equipment that can move along left and right directions relative to frame is driven by same motor 4.Preferably, left and right two parts of frame 1 are substantially identical, and like this, each spray equipment 2 is respectively separately for cleaning the dry net of this rack section below., in a lateral direction, keep a public place clean separately 50% dry net of two spray equipments 2, wherein preferably approximately has the intersection of 10cm, to guarantee that whole dry net all can spray to dry net clean-preserving agent.Motor 4 is arranged on a side of frame 1, is driven and is made two spray equipment 2 synchronous operations by same motor, operates easylier, and the efficiency of keeping a public place clean is higher.The nozzle of nozzle assembly 3 is 70-100 mm with the distance of dry net, like this, can ensure good spraying effect, and what neither can spray is too much, causes waste, also can not have very little the effect of keeping a public place clean preferably because of spraying.In the present embodiment, frame 1 is made for stainless steel material, and is formed in one, and like this, frame 1 quality is more stable, can adapt to better operating environment.
consult Fig. 3, Fig. 3 has schematically shown the conveyance conduit of dry net clean-preserving agent.In Fig. 3, dry net clean-preserving agent is carried by two membrane pumps that are arranged on two dry net clean-preserving agent pipelines respectively, and two conveyance conduits are respectively used to be connected to the feeding opening 32 of two nozzle assemblies 3.Just can control the feed status of two dry net clean-preserving agent pipelines by controlling the duty of two membrane pump M, can realize independent conveying or two-tube conveying or all stop carrying, spray dry net clean-preserving agent or stop spraying thereby control two spray equipments.Compressed air of the present utility model can be provided by air compressor machine, and is delivered to air inlet 31 by compressed air piping.Compressed air piping used herein can be prior art conventional for delivery of compressed-air actuated pipeline, and provide compressed air with air compressor machine conventional in prior art, thereby do not provide and pipeline is described in more detail compressed-air actuated herein.
because clean-preserving agent has certain viscosity and atomizer aperture is less, if sneak into paper hair, nozzle medicine, gas joint or pipe connect the nozzle that all can cause such as anti-cannot atomization, therefore need frequent admission cover inspection sprinkling equipment ruuning situation, once find cannot atomization, dredging nozzle method is as follows:
(1) spray equipment has two covers, in the time that a nozzle moves on to transmission side (or fore side), another nozzle is just in the centre of frame, incompatible dredging nozzle can two people matches, a people is in vapour cover is walked on stage, and a people is under vapour cover, in the time that nozzle moves to fore side (or transmission side), people under signal vapour cover stops mobile, the nozzle of dredging fore side (or transmission side).
(2) while dredging nozzle in normal productive process, compressed air and confession Teat pipette all do not need to stop, only the control valve on nozzle need to be outwarded winding, allow the clean-preserving agent that is mixed with impurity flow out, generally, nozzle can be dredged, and is that nozzle is transferred and is stained with paper hair or sicker also can affect atomizing effect sometimes.
the utlity model has following advantage:
1, keep dry net clean, reduce the number of times of the dry net of stop cleaning, reduce steam mono-consumption, improve paper machine operation efficiency and output.
, dry net can increase at least 3-4 month service life, monthly substantially can reduce by 50000 yuan of left and right of dry net cost thus.
above specific embodiment of the present utility model is illustrated; but protection content of the present utility model is not only limited to above embodiment; under of the present utility model, in technical field, the common knowledge of a GPRS just can be carried out diversified change within the scope of its technology main idea.
