Abstract
The utility model relates to an equal high-speed high-efficiency dreg remover which belongs to a pulp dreg removing device in papermaking. The structure of the equal high-speed high-efficiency dreg remover is that the upper end of a dreg remover is provided with a flow guiding device, and the lower end is provided with a dreg discharge nozzle, wherein, a straight cylindrical section flow guiding chamber is arranged inside the flow guiding device; the upper end of the straight cylindrical section flow guiding chamber is connected with a pulp discharge port, and the lower end of the straight cylindrical section flow guiding chamber is connected with the dreg discharge nozzle; one side of the flow guiding chamber is connected with a pulp feeding port. The equal high-speed high-efficiency dreg remover forms an inverted cone shape, and a pulp feeding pipe is a circle changing equal height rectangular pipe. The equal high-speed high-efficiency dreg remover has the advantages of simple structure, convenient operation, thorough impurity removing, high productive efficiency, low cost, constant speed of running and less loss of favorable pulp; eddy current in pulp is eliminated, and the dreg discharge nozzle is easy to replace, so that the utility model can be widely used for removing impurities in paper pulp.
Description
The efficient scummer of the utility model constant speed belongs to the paper pulp deslagging device in the papermaking.
Scummer in the prior art, its defective is a complex structure, volume is big, inner wall coarse, resistance is big, and the power power consumption is high, and slagging-off not exclusively produces eddy current, and magma runs off serious, and production efficiency is low, and the cost height is difficult for applying.
The purpose of the efficient scummer of the utility model constant speed is to overcome above-mentioned shortcoming and design the efficient scummer of a kind of constant speed, and it is to adopt circle to become contour rectangle pulp-inlet pipe, straight cylinder section guiding device is set on the stock inlet, make slurry stream near wall, make circular motion rapidly, eliminate eddy current.The scummer segmentation increases tapering, and the pressure that fills vacancies in order of precedence reduces centrifugal force, promotes that the impurity in the magma regains centrifugation.Reach purification slagging-off purpose, magma does not run off, the production efficiency height, and slagging-off scope concentration is 0.5-1.5%, is widely used in the paper pulp slagging-off industry.
The efficient scummer of the utility model constant speed takes following technical scheme to realize, it is that the scummer upper end is provided with straight cylinder section diversion chamber and pulp-inlet pipe and grout outlet, pulp-inlet pipe and grout outlet are connected in air deflector, the diversion chamber upper end connects grout outlet, the lower end connects deslagging chews, and scummer is inverted cone, and pulp-inlet pipe becomes contour rectangular tube for circle, pulp-inlet pipe and grout outlet and deslagging are set on the air deflector chew, be provided with diversion chamber in the air deflector.Paper pulp stream is close to wall in the pulp-inlet pipe, makes circular motion rapidly in an orderly manner, eliminates the eddy current after slagging-off enters the mouth.The segmentation of scummer awl circle increases tapering, and the pressure that fills vacancies in order of precedence falls the centrifugal force that is caused and reduces, and makes the impurity in the paper pulp regain bigger centrifugation, reaches the purpose of pulp purifiation slagging-off.
The effect of the efficient slag device of the utility model constant speed is simple in structure, and is in light weight, easily installs, easy to operate, the removal of impurity is thorough, the production efficiency height, and cost is low, the constant speed operation, good slurry does not run off, and eliminates and advances to starch backwash, and it is long that the life-span is chewed in slagging-off, easily change, the impurity scope in the paper pulp of being widely used in is in 0.5-1.5% slagging-off.
The efficient scummer of the utility model constant speed will describe in further detail in conjunction with the accompanying drawings.
Accompanying drawing is the structural representation of the efficient scummer of the utility model constant speed.
1-diversion chamber, 2-pulp-inlet pipe, 3-air deflector, 4-grout outlet, 5-scummer, 6-deslagging is chewed
With reference to accompanying drawing, the efficient scummer of the utility model constant speed, it is by scummer 5 upper ends air deflector 3 and lower end to be set deslagging is set chews 6, straight cylinder section diversion chamber 1 upper end connection grout outlet 4 is connected deslagging with the lower end and chews 6, and diversion chamber's 1 one sides connect pulp-inlet pipe 2, and scummer 5 is inverted cone, pulp-inlet pipe 2 becomes contour rectangular tube for circle, make paper pulp stream near wall, make circular motion rapidly in an orderly manner, eliminate the eddy current after paper pulp enters scummer 5.Scummer 5 cone segmentations increase tapering, increase progressively the reduction of ftercompction power successively and cause centrifugal force to reduce, and impel the impurity in the paper pulp to regain bigger centrifugation.Scummer 5 paper feeds slurry impurity concentration scope is at 0.5-1.5%, and paper pulp does not run off, and pulp purifiation impurity is thorough.
The efficient scummer embodiment of the utility model constant speed, it is to be provided with air deflector 3 and lower end by scummer 5 upper ends deslagging is set chews 6, be provided with diversion chamber 1 in the air deflector 3, straight cylinder section diversion chamber 1 upper end connection grout outlet 4 is connected deslagging with the lower end and chews 6, diversion chamber's 1 one sides connect pulp-inlet pipe 2, scummer 5 is inverted cone, and pulp-inlet pipe 2 becomes contour rectangular tube for circle, and the inverted cone segmentation increases tapering.Paper pulp enters scummer 5 backs and eliminates eddy current, reaching increases to advance to starch pressure, reduce the Yang Cheng of pump, under centrifugal action, impurity is moved down the outer eddy flow of formation zone along the wall direction, chewing 6 by deslagging discharges, clean good slurry light specific gravity enters from bottom to top and is formed centrally low pressure internal layer eddy flow zone in the scummer 5, upwards enters grout outlet 4 along center convolution.Scummer 5 inverted cone segmentations increase tapering, make the heavy seeds in the paper pulp obtain slagging-off more completely under centrifugal action.Scummer 5 impurity concentration scope in former paper pulp is to regulate in 0.5-1.5% to use, and purifies paper pulp rate height, and paper pulp does not run off.
