Description
Technical field
The utility model belongs to field of papermaking, and in particular to a kind of novel addition of paper machine wet end chemicals online injection
Device.
Background technique
In paper industry, there are many ways to traditional inlet pipe adds chemicals online form, 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 aperture 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 directly contacts in the direction of pulp flow with main slurry inside pipe wall, will cause for a long time
Inside pipe wall corrosion is starched, stock quality is directly affected.
Utility model content
Purpose of the utility model is to solve the above-mentioned problems of the prior art, a kind of papermaking chemical product is provided and is existed
Line injector.
To achieve the above objectives, the present invention adopts the following technical solutions: a kind of papermaking chemical product online injection device, packet
Central tube, interlayer pipe and outer tube are included, between the centrally disposed pipe of interlayer pipe and outer tube, central tube, interlayer pipe and and outer layer
It is connected, is bolted between the flange arrangement, central tube end point is provided with central tube by flange arrangement between pipe
Spray head, the outer tube are provided with fixing head close to one end of central tube spray head, pass through fixing clamp between fixing head and outer tube
It is fixed.
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 spray head is connected through a screw thread with central tube.
The fixing head front end and the hole of main slurry Guan Suokai, which pass through, to be welded and fixed.
The fluid injection end is provided with hand valve and check-valves.
The utility model has the beneficial effects that: there is the papermaking chemical product of three-decker to infuse online for the utility model setting
Enter device, can achieve being sufficiently mixed for chemicals and slurry, sufficiently to realize the functional effect of wet-end chemicals；Central tube spray head
With central tube using being threadedly coupled, keep replacement vulnerable part convenient and efficient；In addition injector is whole by outer tube front end position and solid
It is clamping fixed that fixed first end is fixed, and makes integral installation, easy removal.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, the utility model provides a kind of papermaking chemical product online injection device, including central tube 7, interlayer pipe 6
With outer tube 4, between the centrally disposed pipe 7 of interlayer pipe 6 and outer tube 4, central tube 7, interlayer pipe 6 and between outer tube 4 lead to
Flange arrangement connection is crossed, is connected between flange arrangement by bolt 5,7 end point of central tube is provided with central tube spray head 1, outer layer
Pipe 4 is provided with fixing head 2 close to one end of central tube spray head 1, fixed by fixing clamp 3 between fixing head 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 guaranteed three layers internal
The leakproofness and stability of structure.
Central tube spray head 1 is connected through a screw thread with central tube 7.1 position of central tube spray head is directly contacted with slurry, is being used
Abrasion can be generated in the process, and being connected through a screw thread keeps replacement vulnerable part convenient and efficient.
2 front end of fixing head and the hole of main slurry Guan Suokai, which pass through, to be welded and fixed.It is fixed on fixing head 2 on main slurry pipeline, infuses
Entering device can integrally be separated by unclamping fixing clamp with main slurry pipeline, integral installation, easy removal.
Fluid injection end is provided with hand valve 8 and check-valves 9.
When in use, papermaking chemical product online injection device is answered for papermaking chemical product online injection device provided by the utility model
In papermaking constant part, fluid is plain boiled water in machine in central tube 7, and fluid is papermaking chemical product, outer tube 4 in interlayer pipe 6
Interior fluid is plain boiled water or papermaking chemical product in machine；Determine that same chemicals makes in same position according to the size of pipeline section product
With the quantity of online injector, every 0.1 square metre uses 1, and is evenly distributed in main slurry pipe circumference, and same chemicals exists
Same position at least uses an online injection device；Papermaking chemical product enters from interlayer pipe 6 and the machine words spoken by an actor from offstage that enters from outer tube 4
Water or second of papermaking chemical product are tentatively mixed, and mixed material is sprayed when entering main slurry pipeline from central tube
Plain boiled water sufficiently breaks up dilution in the machine entered, reaches chemicals and the well-mixed purpose of slurry.
The above is preferred embodiments of the present invention, it is noted that for those skilled in the art,
The present utility model is not limited to the above embodiments, under the premise of not departing from the utility model general idea, can also make
Several changes and improvements, these also should be considered as the protection scope of the utility model.
