Abstract
The utility model provides a paper grade (stock) high pressure spraying system, includes spray piping (2), uniformly spaced be provided with a plurality of nozzles (4), its characterized in that are gone up in spray piping (2): the intercommunication is gone up in spray piping (2) has vacuum pipe (6), install first control valve (8) on vacuum pipe (6), the side -mounting of intaking of spray piping (2) has at least one deck filter screen (10), the play water side -mounting of spray piping (2) has second control valve (12). The utility model discloses have more high efficiency, and safer and more environmental protection.
Description
Technical field
The utility model relates to a kind of paper grade (stock) high-pressure spraying system.
Background technology
In high-speed paper machine running, forming web and woollen blanket play a part very important in dehydration.Slurry is at shaping web forming and slough a large amount of moisture.But forming web and woollen blanket are in use, can be blocked, make dirty by fiber fines, filler, resin etc. gradually; In addition, the sediment that some chemical reactions generate and the product of bacterial activity also can be made dirty forming web and woollen blanket, and dirty forming web and woollen blanket dewatering efficiency can reduce greatly, thus cause drying section steam consumption quantity greatly to increase, cause paper defects simultaneously, be lowered into paper quality.
For ensureing that forming web and woollen blanket keep clean, general paper mill selects high-pressure spray device to clean, successful, but, in recent years due to environmental protection pressure, most of paper mill adopts Recirculating white water to clean, although economize energy, containing a large amount of fiber fines and filler molecule in plain boiled water, high-pressure spraying system is caused easily to block, high pressure nozzle is loose to be spent or directly blocks, and causes forming web and the dehydration of woollen blanket portion to be deteriorated, greatly affects paper machine and normally produce.
At present for above-mentioned phenomenon, artificial mode can only be adopted to carry out nozzle and pipe-dredging, must stop spray system while dredging, impact is produced.Dredging nozzle carries out in paper machine operation process, can cause accident, damage employee.Therefore, research and develop the artificial dredging of a kind of new method replacement and there is very large meaning.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of more high efficiency, paper grade (stock) high-pressure spraying system that is safer and more environmental protection.
For solving the problems of the technologies described above, the utility model provides a kind of paper grade (stock) high-pressure spraying system, comprise spray piping, evenly spacedly on described spray piping be provided with multiple nozzle, described spray piping is communicated with vacuum pipe, described vacuum pipe is provided with the first control, the influent side of described spray piping is provided with at least one deck screen pack, and the water outlet side of described spray piping is provided with the second control valve.
Described first control valve is ball valve.
Described second control valve is ball valve.
The internal diameter of described vacuum pipe is less than the internal diameter of described spray piping.
The internal diameter of described vacuum pipe is 1/2nd of the internal diameter of described spray piping.
Described nozzle is rotary two-hole nozzle.
Compared with prior art, the beneficial effects of the utility model are: because the utility model is when spray nozzle clogging, by closing the second control valve, open the first control valve to vacuumize, tamper is extracted out by the mode utilizing negative pressure of vacuum to aspirate from suction nozzle, without the need to manually participating in so can not damage employee, and efficiency is high, environmental protection again, therefore the utility model has more high efficiency, and safer and more environmental protection.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
In figure: spray piping 2, nozzle 4, vacuum pipe 6, the first control valve 8, screen pack 10, the second control valve 12.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment and accompanying drawing, the utility model is described in further details.At this, exemplary embodiment of the present utility model and illustrating for explaining the utility model, but not as to restriction of the present utility model.
Shown in Figure 1, a kind of paper grade (stock) high-pressure spraying system, comprise spray piping 2, evenly spacedly on this spray piping 2 be provided with multiple nozzle 4, at the influent side of spray piping 2, one or more layers screen pack 10 is installed simultaneously, a ball valve is installed as the second control valve 12 at the water outlet side of spray piping 2, special feature of the present utility model is, spray piping 2 is communicated with vacuum pipe 6, this vacuum pipe 6 is provided with a ball valve as the first control valve 8, during use, the screen pack 10 being positioned at influent side can first filtration fraction impurity, reduce the possibility that nozzle 4 is blocked, but when nozzle 4 blocks, close the second control valve 12, open the first control valve 8 to start to vacuumize, the mode utilizing negative pressure of vacuum to aspirate is discharged after being extracted out from suction nozzle 4 by tamper from vacuum pipe 6, this kind of mode is without the need to manually participating in so can not damage employee, and efficiency is high, environmental protection again.
For bringing better suction effect, make the internal diameter of vacuum pipe 6 be less than the internal diameter of spray piping 2, the internal diameter of preferred vacuum pipe 6 is 1/2nd of the internal diameter of spray piping 2.Nozzle 4 adopts rotary two-hole nozzle simultaneously, and the water column of this kind of nozzle injection is smooth, so penetration power is stronger, water smoke is less, effective, and the life-span is very long, thus can promote the utility model result of use in actual applications.
Claims (6)
