Description
Technical field
The invention belongs to field of papermaking, and in particular to a kind of novel adding apparatus of paper machine wet end chemicals online injection
And its application method.
Background technology
In paper industry, form there are many ways to traditional inlet pipe adds chemicals online, most commonly in master
It starches around pipe plus ring pipe, circulating line has multiple entrances to be inserted directly into main slurry pipe, installation form is all that live directly trepanning is inserted
Enter pipeline welding, integral installation is time-consuming and laborious, and the chemicals that pipeline is directly injected into cannot be mixed uniformly with slurry, be directly affected
The functional effect of wet-end chemicals；Chemicals is in direct contact in the direction of pulp flow and main slurry inside pipe wall, can be caused for a long time
Inside pipe wall corrosion is starched, stock quality is directly affected.
Invention content
The purpose of the present invention is to solve the above-mentioned problems of the prior art, a kind of papermaking chemical product is provided and is noted online
Enter device and its application method.
To achieve the above object, the present invention adopts the following technical scheme that：A kind of papermaking chemical product online injection device, including in
Heart pipe, interlayer pipe and outer tube, between the centrally disposed pipe of interlayer pipe and outer tube, central tube, interlayer pipe and with outer tube it
Between connected by flange arrangement, be bolted between the flange arrangement, central tube end point is provided with central tube nozzle,
The outer tube is provided with gland close to one end of central tube nozzle, is fixed by geometrical clamp between gland and outer tube.
The end face to contact with each other between the central tube, interlayer pipe and outer tube is sealed by sealing strip.
The central tube nozzle is connected through a screw thread with central tube.
The gland front end is with the main hole for starching Guan Suokai by being welded and fixed.
The fluid injection end is both provided with hand valve and check-valves.
The application method of the papermaking chemical product online injection device, papermaking chemical product online injection device is applied in papermaking
In constant part, center tube fluid is plain boiled water in machine, and interlayer tube fluid is papermaking chemical product, and outer layer tube fluid is in machine
Plain boiled water or papermaking chemical product；Determine that same chemicals uses online injection device in same position according to the size of pipeline section product
Quantity, every 0.1 square metre of use 1, and being evenly distributed in main slurry pipe circumference, same chemicals same position at least
Use an online injection device；Papermaking chemical product enters and plain boiled water in the machine that enters from outer tube or makes for second from interlayer pipe
Paper chemicals is tentatively mixed, and mixed material is filled when entering main slurry pipeline by plain boiled water in the machine that is sprayed into from central tube
Divide and break up dilution, reaches chemicals and the well-mixed purpose of slurry.
The beneficial effects of the present invention are：Papermaking chemical product online injection device of the present invention setting with three-decker, can
To reach being sufficiently mixed for chemicals and slurry, fully to realize the functional effect of wet-end chemicals；Central tube nozzle and center
Pipe keeps replacement vulnerable part convenient and efficient using being threadedly coupled；In addition injector is whole by outer tube front end position and gland one
It is clamping fixed that end is fixed, and makes integral installation, easy removal.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and specific embodiments.
As shown in Figure 1, the present invention provides a kind of papermaking chemical product online injection device, including central tube 7, interlayer pipe 6 and outer
Layer pipe 4, between 6 centrally disposed pipe 7 of interlayer pipe and outer tube 4, central tube 7, interlayer pipe 6 and passes through method between outer tube 4
Blue structure connects, and is connected by bolt 5 between flange arrangement, 7 end point of central tube is provided with central tube nozzle 1, and outer tube 4 is leaned on
One end of nearly central tube nozzle 1 is provided with gland 2, is fixed by geometrical clamp 3 between gland 2 and outer tube 4.
The end face to contact with each other between central tube 7, interlayer pipe 6 and outer tube 4 is sealed by sealing strip, is ensured three layers internal
The leakproofness and stability of structure.
Central tube nozzle 1 is connected through a screw thread with central tube 7.1 position of central tube nozzle is in direct contact with slurry, is being used
It will produce abrasion in the process, being connected through a screw thread keeps replacement vulnerable part convenient and efficient.
2 front end of gland is with the main hole for starching Guan Suokai by being welded and fixed.So that gland 2 is fixed on main slurry pipeline, notes
Entering device can integrally be detached by unclamping geometrical clamp with main slurry pipeline, integral installation, easy removal.
Fluid injection end is both provided with hand valve 8 and check-valves 9.
When in use, papermaking chemical product online injection device is applied in papermaking starching for above-mentioned papermaking chemical product online injection device
In system, fluid is plain boiled water in machine in central tube 7, and fluid is papermaking chemical product in interlayer pipe 6, and fluid is in machine in outer tube 4
Plain boiled water or papermaking chemical product；Determine that same chemicals uses online injection device in same position according to the size of pipeline section product
Quantity, every 0.1 square metre of use 1, and being evenly distributed in main slurry pipe circumference, same chemicals same position at least
