Description
Technical field
The utility model relates to a kind of long mesh paper making machine wet end spray equipments, belong to pulp technology for making paper, are particularly suitable for fourdrinier wire
Cleaning is sprayed between paper machine couch roll and drive net roll.
Background technique
The spray equipment that conventional fourdrinier wet end generally uses is a transverse tube, including main jet spray pipe, main water inlet
Pipe and spray water nozzle, spray waterpipe are cylindrical tube, and one end intakes, other end closing, are provided with spray water nozzle on pipeline,
Shower water is sent into spray tube from paper machine transmission side when work, carries out wet end and continuously sprays, effect is to forming net or wite roll
Spray water cleans forming net and wite roll.
For long mesh paper making machine, paper stock is cut at couch roll by water needle after wet end is dehydrated and to form paper web, the paper web being stripped
It shifts to press section, left trimming is adhered to long net surface and remains in operation, and the trimming of this part adherency needs clear in time
Wash clean, first is that will lead to wite roll product slurry, twining slurry, causes forming net deformation of cylindrical, shortens forming net once not washing clean clearly
Service life, while because forming net wire side deforms, cause paper surface streak, product quality decline occur；Second is that cleaning is not done
Only it will lead to the blocking of forming net mesh, wire side mucilage causes paper web hole, breach, brocken spectrum occur, and product quality declines, very
To disconnected paper is caused, production efficiency declines.Conventional method is in couch roll and to drive a piece big yield spray waterpipe of setting between net roll, punching
The trimming of wire side adherency and the paper pulp of middle part wire side remnants are washed, since the trimming adhered on forming net is thick and solid, paper pulp amount is big,
During paper machine runs at high speed, it even if spraying water super large using single transverse tube, but often still can not effectively remove, cause one
Series of problems.
Summary of the invention
The purpose of this utility model is in view of the above problems, providing one kind not only can achieve high-efficiency washing, but also can save
The long mesh paper making machine wet end efficient spray device of water resource and water delivery energy consumption.
To achieve the above object, the utility model provides the following technical solutions: a kind of long mesh paper making machine wet end spray equipment, packet
Main water inlet tube, main jet spray pipe are included, it is characterized in that: fore side time spray waterpipe and transmission is respectively set at main jet spray pipe rear
Side time spray waterpipe, fore side and fore side time spray waterpipe of main jet spray pipe pass through respectively water inlet pipe one and water inlet pipe two with
Transmission side and transmission side time spray waterpipe of main water inlet tube connection, main jet spray pipe also pass through water inlet pipe three and water inlet pipe four respectively
It is connected to main water inlet tube.
Shower water is respectively arranged on the main jet spray pipe, fore side time spray waterpipe and transmission side time spray waterpipe
Mouth, spray water nozzle opening shape can be " one " word seam type, be also possible to other shapes, preferably sector open.
A kind of long mesh paper making machine wet end spray equipment, fore side time spray waterpipe and transmission side time spray waterpipe
Length can arrive one third, preferably a quarter for 1/6th of forming net width.
A kind of long mesh paper making machine wet end spray equipment can be used for the phase that fourdrinier machine wet end needs to be rinsed
Position is answered, is especially suitable for being mounted on paper web after forming net removing, flushing of the position to forming net between couch roll and drive net roll.
The technical solution of the utility model is taken, is had the advantages that.
1. installing utility model device between couch roll and drive net roll, wire side can be carried out by main jet shower pipe first
It is whole to rinse, then flushing is further supplemented by fore side and transmission side time spray tube, it can effectively remove the online adherency of forming
Residual trimming, reduce and drive net roll and wite roll product slurry, mucilage, twine slurry, avoid forming net oxygen blast cyanidation, extension forming net use
Service life, while preventing paper streak.
2. whole picture cleaning is more uniform, forming net cleaning effect can be effectively improved, mesh blocking, wire side mucilage is prevented, makes
At paper defects such as paper hole, breaches, broken end is reduced, improves paper machine operation efficiency.
3. the utility model, which overcomes conventional method shower water and flows into from one end, to be caused compared with the single spray tube of tradition
Paper machine whole picture spray hydraulic pressure is uneven, water is different, the drawback of cleaning effect unevenness, and the water of main jet shower pipe is entered in the technical program
It is respectively fed to from two sides, entire main jet shower pipe water spray is more uniform, and cleaning effect is more preferable.
4. compare the single transverse tube spray equipment of tradition, the utility model is the case where reaching forming net same cleaning effect
Under can save 10% or more water spray, while significantly reducing water delivery energy consumption.
Above-mentioned technical proposal is described further with reference to the accompanying drawings and examples.
