Abstract
The utility model relates to a pulp dewatering machine with a conic roller having arc surface. The utility model is suitable for extracting the thick black liquor, concentrating pulp, preparing feed applying wet method, etc. in paper making industry. The utility model comprises a driving part (1), a feeding part (3), and an extruding roller of a discharging part; the extruding roller is composed of two arc-surface conic rollers which are relative and the shaft lines of the two conic rollers can form the definite angle; a plurality of dewatering hole is distributed on the arc-surface conic rollers. The dewatering machine has the advantages of high work efficiency, high work reliability, high dewatering rate, and remarkable energy and water saving effect.
Description
The utility model relates to a kind of cambered surface awl roller slurries dewaterer, the concentrated black liquid that is applicable to paper-making industry extracts, slurry concentrates, wet feed preparation etc., also can be used for sludge dewatering and starch, medicine, chemical industry, food in the environment-friendly engineering, brewage, in the industry such as chemical fibre squeeze the juice, wash, dewater concentrated etc.
Existing dehydration equipment, different according to the physical property of using industry and slurries, on principle, can be divided into centrifugal dehydration, precipitation dehydration and extrusion dehydration etc.The plant equipment of extrusion dehydration mainly contains piston extrusion machine, pair roller type extruder, spiral extruder etc.Piston extrusion machine is owing to be non-continuous operation, and therefore, the slurries disposal ability is low.The pair roller type extruder is unfavorable for charging because the pan feeding angle of nip is big, thereby the disposal ability of unit interval is reduced.Spiral extruder is owing to be to be advanced by screw rod rotation, and the sliding material (as straw pulp liquid) of commute skids easily in extrusion process, stops up, simultaneously since material group around, rubbing can the follow-up slurry pool quality of influence.These equipment all exist efficient low to some extent, and dehydration rate is low, and energy consumption is big, poor reliability, shortcomings such as narrow application range.
The purpose of this utility model provides a kind of new cambered surface awl roller slurries dewaterer, and this dewaterer treating capacity is big, the efficient height.
The purpose of utility model realizes by following mode:
Cambered surface awl roller slurries dewaterer comprises running part, feeding part, discharging part and compression roller, and compression roller is made up of two cambered surface awl rollers relative, that axis is angled, is distributed with dewatering hole on the cambered surface awl roller.
Slurries enter in two working chambers of boring between the rollers by the top of feeding part from compression roller, under the cambered surface awl roller strap of rotation synchronously is moving, carry out extrusion dehydration, and moisture content is discharged by the dewatering hole on the awl roller, and the solids after concentrating is from following discharge.
Because two awl roll axis are angled, form the extruding working chamber of descending gradual change between the two awl rollers, the feeding mouth sectional area is big, and the discharging opening sectional area is little, helps improving the inlet amount and the operating efficiency of dewaterer like this.
Cambered surface awl roller slurries dewaterer provided by the utility model has following advantage:
1, continuous operation, high efficiency;
2, because the feeding angle of nip is little, help charging, the functional reliability height;
3, owing to the working chamber and the extruding workspace that are gradual change are big, the dehydration rate height reduces the dewatering cycle number of times, and the energy-saving and water-saving effect is remarkable;
4, the material loss rate is low;
5, be suitable for the concentration of slurry wide ranges.
Below in conjunction with accompanying drawing, the utility model is described in detail.
Accompanying drawing 1 is the structural representation of boring roller slurries dewaterer according to first kind of cambered surface that the utility model provides; Accompanying drawing 2 is structural representations of the 2nd kind of dewaterer; Accompanying drawing 3 is structural representations of the 3rd kind of dewaterer.
As shown in the figure, cambered surface awl roller slurries dewaterer comprises running part (1), feeding part (3), and discharging part and compression roller, compression roller is made up of two cambered surface awl rollers relative, that axis is angled (4), is distributed with dewatering hole on the cambered surface awl roller.
Shown in accompanying drawing 1,2, two awl rollers connect by one or two candan universal joint shaft coupling (2), and the clutch end of running part is connected with one of them awl roller.Another awl roller rotates synchronously with previous awl roller under the drive of shaft coupling.As shown in Figure 1, the connection between the two awl rollers is to adopt a gimbal coupling (2), and 4 strong points are arranged this moment.As shown in Figure 2, the connection between the two awl rollers is to adopt two cross joint shaft couplings (2), and 3 strong points are arranged this moment.
As shown in Figure 3, two awl rollers are arranged on the line shaft of running part by two ball splines (6) respectively, and the outer hand hay cutter of two awl rollers is respectively arranged with ball pivot adjusting angle mechanism (7), and the pinch roller roof pressure of ball pivot adjusting angle mechanism is on the lateral surface of two awl rollers.Adjusting angle mechanism is used to adjust the angle between the two awl rollers, thereby makes cambered surface awl roller slurries dewaterer have adjustable compression ratio.
Claims (3)
