Description
Technical field
The utility model technology belongs to slurrying field, is specifically related to a kind of system that pulping system provides low dense slagging-off that can be.
Background technology
Paper industry high speed development, paper making raw material shortage problem is more and more obvious, various waste paper and inferior timber are also used to slurrying, in raw material, there is the more grains of sand, coal ash and other granular impurity, if not in time the slag in paper pulp is processed, can affect paper quality, and pipeline and equipment are caused to damage.
In traditional low dense slag removing system, one section is removed the gred and removes the gred and be arranged in Stall into stock pump into stock pump and three sections into dense slagging-off of stock pump, two sections low, scalping is starched with one section of two sections of next good slurries insertion and is removed the gred and send into one section low dense scummer after stock pump inlet tube, one section is come tailings and three sections to come good slurry to insert two sections to remove the gred send into two sections low dense scummers after stock pump inlet tube, and two sections are come tailings to insert three sections to remove the gred send into three sections low dense scummers after stock pump inlet tube.
Traditional low dense slag removing system shortcoming is clearly: one section is removed the gred and removes the gred and be arranged in Stall into stock pump into stock pump and three sections into dense slagging-off of stock pump, two sections low, has increased pump lift, thereby has increased investment cost and operating cost; Scalping is starched and from second floor, is entered one section of Stall and remove the gred into stock pump, one or two sections of tailings enter respectively two sections low dense slagging-off from second floor and remove the gred and sending to second floor into stock pump into stock pump and three sections, increased duct length on the one hand, also increased on the other hand the wearing and tearing of pipeline, increased maintenance cost and repair difficulty.
Utility model content
The utility model patent technical problem to be solved is the weak point existing for above-mentioned prior art, provides a kind of new slurrying low dense slag removing system.
The purpose of this utility model is achieved through the following technical solutions.
The low dense slag removing system of slurrying, one section low dense slagging-off white water chest and two sections low dense slagging-off white water chests are arranged in second floor, and reserve embedded part on low dense slagging-off white water chest, welding one section low dense scummer of channel steel support and two sections low dense scummers; Scalping is starched and two sections low dense scummers come good slurry to remove the gred and send into two sections low dense scummers after stock pump inlet tube with one section of 45° angle insertion; Two sections are removed the gred and stretch into one section low dense slagging-off white water chest into stock pump inlet tube, and add 90 ° of elbows at inlet tube, 250～350 mm at the bottom of elbow distance from bottom pond, one section low dense scummer tailings from pond with 45 ° of insertion inlet tubes; Three sections are removed the gred and stretch into two sections low dense slagging-off white water chests into stock pump inlet tube, and add 90 ° of elbows at inlet tube, 250～300mm at the bottom of elbow distance from bottom pond, two sections low dense scummer tailings from pond with 45 ° of insertion inlet tubes; One section low dense scummer tail slurry and three sections low dense scummers come good slurry to remove the gred and send into two sections low dense scummers after stock pump inlet tube with two sections of 45° angle insertions; Two sections low dense scummer tail slurries remove the gred and send into three sections low dense scummers after stock pump inlet tubes with three sections of 45° angle insertions; The moisturizing of one section low dense slagging-off white water chest and two sections of low dense slagging-off white water chests is by supplementing white water pump from Stall suction.Water inlet direction is that pump inlet relative direction pumps into, and water inlet angle is for to enter in pond from top, pond with 30～60 ° of oblique cuttings.
The design of optimizing can be: one section low dense slagging-off white water chest and two sections low dense slagging-off white water chest height are 1～3m, and length can suitably be done greatly according to place, guarantees the static suction time 1～3min of plain boiled water in pond, at the bottom of pond, to pump inlet direction, walks 1～3 °, slope.
Can be: supplementing water and the pond liquid level of one section low dense slagging-off white water chest and two sections of low dense slagging-off white water chests are chain that it is highly that the liquid level gauge mode of boxing out is that pre-buried Dn65～100 are with the pipe of anti-hydrofoil ring higher than 300～500mm at the bottom of pond that liquid level gauge is boxed out further.
The utility model is by preferred arrangement, makes one section to remove the gred and remove the gred and remove the gred and into slurry pump lift, reduce the height of a floor into stock pump and three sections into slurry, two sections, and single pipe reduces the length of a floor.The 650 BDT/D OCC Pulping Lines of take are example, suppose that story height is 7m, described in the utility model patent, stock pump power of motor 250kW is entered in one section of scalping, two sections are removed the gred into stock pump power of motor 90kW, and three sections are removed the gred into stock pump power of motor 45kW, and traditional low dense slag removing system power of motor is respectively 350kW, 125kW, 60kW, saves the about 150kW of installation, year using electricity wisely 733333kWh.In addition, one section and two sections of tailings are directly inserted into stock pump entrance after out, have reduced pipe wear.The water inlet direction of one section low dense slagging-off white water chest and two sections of low dense slagging-off white water chests and pump inlet relative direction, water inlet angle, for to enter in pond with 45 ° of oblique cuttings at the bottom of pond, is conducive to slurry and screenings to pour into stock pump Way in.Remove the gred and add 90 ° of elbows into stock pump inlet tube front portion, be conducive to suction pond prime cement and the screenings of maximum.
