More than the component devices and the operational process thereof of the system of preparation slurry provided by the present invention described in detail, below respectively to the integral part of the system of preparation slurry of the present invention: the structure and the setting thereof of riffler and knot screen describe in detail.
Extremely shown in Figure 4 as Fig. 2, described riffler 106 comprises cell body 71, inlet 72 and exports 73, the slurries of the small particle size raw material that described sorting equipment 102 is discharged or itself and water formation enter in the described cell body 71 by the inlet 72 of described riffler 106, described cell body 71 comprises sidewall 74 and bottom 75, described outlet 73 is arranged on the described sidewall 74, and described bottom 75 has at least one bossing 76 and/or at least one sunk part 77.
In riffler 106, the slurries 80 that are mixed with the small particle size raw material are in flow process, because the density of tiny foreign material (as the grains of sand) precipitates more greatly and at first with respect to the density of raw material and water, on the bottom 75 of riffler 106, form sedimentary tiny foreign material 82, and the density of raw material flows than gently being suspended in the water and with water.By making the slurries that carry feed particles flow out and make feed particles separate, thereby realize the removing of tiny foreign material (as sand) with the grains of sand from exporting 73.
In riffler 106, inlet 72 can be arranged on the position that can make slurries 80 flow into cell body 71 arbitrarily, described inlet 72 can be the opening (as shown in Figure 3) that is positioned on cell body 71 sidewalls, also can be the pipeline that is placed on cell body 71 sidewalls or gos deep into cell body inside.In order sedimentary tiny foreign material 82 not to be caused interference, further improve the desilting effect, preferred described inlet 72 is arranged on the middle and upper part or the top of cell body 71, further the top of preferred described inlet 72 and the distance between the bottom 75 (" and the distance between the bottom 75 " described in the present invention all refer to and bottom 75 bottom between vertical range) be the 80-100% of the vertical height of cell body 71 these sidewalls (being provided with the sidewall of inlet 72).Further preferably, for the ease of flowing of slurries 80, also in order effectively to improve the desilting effect of the groove that removes sand, described inlet 72 is separately positioned on two relative sidewalls 74 with outlet 73, particularly when the cross section (cross section as shown in Figures 2 and 3) of described riffler be rectangle or when trapezoidal, further preferred described inlet 72 is separately positioned on distance two relative sidewalls 74 far away with outlet 73, like this, big or small identical at other condition such as riffler, can obtain long desilting disengaging time under the identical situation of slurries 80 flow velocitys, thereby effectively improve the effect of removing sand.The size of described inlet 72 and outlet 73 can be determined according to actual needs.
Described outlet 73 can be arranged on and can make slurries 80 flow out the position of cell body 71 arbitrarily, and preferably as mentioned above, described outlet 73 is arranged on the sidewall relative with the 72 place sidewalls that enter the mouth.Stay in the cell body 71 in order effectively to make sedimentary tiny foreign material 82, further improve the desilting effect, preferred described outlet 73 is arranged on the middle and upper part or the top of cell body 71, further preferred described outlet 73 bottom and the distance between the bottom 75 be the 50-95% of the vertical height of cell body 71 these sidewalls (being provided with the sidewall of outlet 73).Further under the preferable case, the distance between the top of described outlet 73 and the bottom 75 less than described inlet 72 bottom and the distance between the bottom 75, export 73 like this and form the form that is similar to overflow weir.
Preferably, outlet 73 can comprise baffle plate, and regulates the position and the size of outlet 73 by baffle plate.Particularly, by hide the bottom of outlet 73 with baffle plate, can regulate outlet 73 bottom and the distance between the bottom 75, the size that can also regulate outlet 73.Obviously, also can on the sidewall 74 at outlet 73 places, form the opening that extends through the bottom of sidewall 74 from the top of sidewall 74 downwards, use the part that a plurality of baffle plates cover this opening can form outlet 73, by regulating the position of a plurality of baffle plates, can free adjustment export 73 position and size.
Distance between outlet 73 and the bottom 75 can be regulated, and on the one hand, when the sidewall at outlet 73 places was piled up, the position of heightening outlet 73 can prevent that the grains of sand from overflowing in that the grains of sand are more; On the other hand, when precipitation also takes place greatly because of autologous density in the cassava particle, flow velocity difference according to slurries 80, when the cassava particle flow to the sidewall at outlet 73 places with water, the height difference of cassava particle in cell body 71, because riffler 106 can only allow to export the above water of the height at 73 places and the cassava particle flows out, by reduce to export 73 and bottom 75 between distance, can allow cassava particle as much as possible to flow out with water.
Among the present invention, in order to prevent that the influence of flowing water flow above it of sedimentary tiny foreign material 82 from moving of streamwise being taken place down, thereby accumulate on the sidewall at outlet 73 places, perhaps overflow from exporting 73 when overheap, the bottom 75 of the cell body 71 of riffler 106 has at least one bossing 76 and/or at least one sunk part 77.Preferably, bottom 75 has a plurality of bossings 76 and/or a plurality of sunk part 77, and these a plurality of bossings 76 and/or a plurality of sunk part 77 are promptly arranged along the flow direction of slurries 80 along from the 72 direction arrangements to outlet 73 that enter the mouth.
Sedimentary tiny foreign material 82 are deposited on the bottom of cell body 71; when sedimentary tiny foreign material 82 are subjected to the influence of current of its top and streamwise when moving, the grains of sand can move in the sunk part 77 or be stopped by bossing 76 and can not continue streamwise and move.Even the grains of sand are deposited on the top of bossing 76 at the beginning, this part grains of sand also can move with the current of its top, is deposited on sunk part 77 then bottom.Therefore, sedimentary tiny foreign material 82 can not move to the sidewall at outlet 73 places basically, thereby prevent that the grains of sand are stacked into outlet 73 and overflow from exporting 73.
In order to prevent that further sedimentary tiny foreign material 82 are subjected to the mobile influence of the current of top, on cross section shown in Figure 2, be longitudinal cross-section (being parallel to from entering the mouth 72 to outlet 73 direction and perpendicular to the cross section of horizontal plane), bossing 76 and sunk part 77 form trapezoidal.Certainly, bossing 76 and sunk part 77 can also form the shape that tiny foreign material 82 streamwises that can help barrier deposition arbitrarily move, for example waviness, trilateral etc.Preferably, bossing 76 and sunk part 77 form the inclined-plane that has horizontal by 30-60 °, thereby help stopping that grains of sand streamwise moves.
Certainly, the bottom 75 of riffler 70 also can have a sunk part 77 (as shown in Figure 3), perhaps has a bossing 76.When bottom 75 has a bossing 76 or a sunk part 77, can suitably increase the size of bossing 76 and sunk part 77.As shown in Figure 3, the amount of the grains of sand that can hold in the sunk part 77 is equivalent to the summation of the amount of the grains of sand that each sunk part 77 can hold among Fig. 2.
In order to hold the grains of sand effectively and to prevent that the grains of sand from moving freely, preferably, bossing 76 and/or sunk part 77 streamwises are arranged on the postmedian of bottom 75.When described bottom 75 has a plurality of bossings 76 and/or sunk part 77, and these a plurality of bossings 76 and/or sunk part 77 streamwises are arranged the postmedian that is arranged on bottom 75.Wherein, the area percentage of the shared bottom 75 of bossing 76 and sunk part 77 is 40-60%.Distance between the top of described bossing 76 and the bottom 75 be not more than outlet 73 bottom and the distance between the bottom 75, further the height relief of preferred bottom 75 (the top of bottom 75 and bottom between vertical range) with the ratio of the height of the sidewall at outlet 73 places be 1: 5-1: 3.Described bossing 76 can be integrally formed with cell body bottom 75, also can be for being fixed on the baffle plate of bottom 75.Described sunk part 77 can be integrally formed with cell body bottom 75, also can be the groove between a plurality of bossings 76.
When feed particles (as the cassava particle) swam on the water surface fully, this feed particles can obtain collecting basically by flowing out outlet 73, but also can some feed particles be subjected to the obstruction of the grains of sand and be deposited to sedimentary tiny foreign material 82 with the grains of sand.In addition, because the density of feed particles is bigger, feed particles also can be sunk in water.In this case, if flow velocity is not enough, when water flow to the sidewall at outlet 73 places, some feed particles may also be deposited to the below, position of outlet 73, can not flow out from exporting 73, and and then deposit to the top layer of sedimentary tiny foreign material 82, thereby cause waste.
For addressing this problem, preferably, riffler 106 comprises can jet-stream wind and/or the jet apparatus of current.This jet apparatus be arranged on sedimentary tiny foreign material 82 the top and can be towards the top layer jet-stream wind and/or the current of sedimentary tiny foreign material 82, thereby the small particle size feed particles that drives the top layer of sedimentary tiny foreign material 82 is suspended in the water again, and flows out outlet 73 with the water of sedimentary tiny foreign material 82 tops.In this process; jet apparatus can spray the air-flow and/or the current of suitable intensity; make feed particles in the top layer of sedimentary tiny foreign material 82 float to position away from sedimentary tiny foreign material 82; though this may make some grains of sand in the sedimentary tiny foreign material 82 also floating; but the grains of sand can sink rapidly because density is big, therefore can not taken away by current basically.
Particularly, as shown in Figure 2, jet apparatus comprises at least one spray tube 78.Each spray tube 78 comprises body and a plurality of hole P that are positioned on the body separately, and air-flow and/or current spray by hole P.Obviously, can use various pumps or suction unit to make hole P jet-stream wind and/or current.
Each spray tube 78 can be set to across two of riffler 70 relative sidewalls, for example, can laterally be arrangeding in parallel along riffler 70, perhaps a kind of embodiment as shown in Figure 2 is like that along the parallel longitudinal setting of riffler 70, also can be along being predetermined angle and be arrangeding in parallel with horizontal and vertical.Certainly, spray tube 78 also can be arranged in a crossed manner.On each spray tube 78 a plurality of hole P can be set, according to the layout of spray tube 78, preferably have 10 holes on every meter the body, the diameter in hole can be 3-6mm.
Because the desanding operating continuity, the thickness of sedimentary tiny foreign material 82 may be different in the sand trap 70, are arranged on the top of sedimentary tiny foreign material 82 all the time for making spray tube 78, and preferably, the distance between the body of spray tube 78 and the bottom 75 can be regulated.For example, can spray tube 78 across two sidewalls at least one on slideway is set, at least one end of spray tube 78 can be arranged in this slideway and along this slideway and slide, thereby can be along the vertical height direction adjusting spray tube 78 of described two sidewalls and the distance between the bottom 75.
Preferably, hole P is set to alignment recess part 77 and/or bossing 76 and inlet 72 and/or exports the groove that forms between the sidewall at 73 places.Just, when bottom 75 has sunk part 77 (comprise and depression that bottom 75 is integrally formed and two bossings 76 between the groove that forms), hole P alignment recess part 77; When the bottom only has a bossing 76, hole P alignment bumps part 76 and inlet 72 and/or export groove between 73.
The hole P of spray tube 78 preferably is set to spray towards the top layer of sedimentary tiny foreign material 82, and therefore, hole P preferably is set to 75 injections towards the bottom.More preferably, hole P is set to spray downwards along being angle A with the flow direction of slurries 80 or horizontal plane, the axis that is hole P sprays downwards horizontal by angle A, angle A is preferably 30-60 °, thereby sedimentary tiny foreign material 82 in a big way in drive the cassava particle, avoid making the grains of sand also floating simultaneously.As Fig. 2 and shown in Figure 4, spray tube 78 is provided with along horizontal (filled arrows is depicted as flow direction among Fig. 4, and flow direction is vertical) of riffler 106, and hole P is set to favour downward 45 ° of horizontal direction (shown in Fig. 4 hollow core arrow) and sprays.
Spray tube 78 is arranged on outlet helps the injected air-flow of cassava particle near 73 and/or current blow and taken away by current rapidly, but be arranged near the air-flow of spray tube 78 injections the outlet 73 or the speed of current and will be controlled at proper range, avoid the grains of sand are also blown and take away, for example 1m/s.In addition, can also spray tube 78 be set in the position away from outlet 73, in this case, spray tube 78 can provide than the air-flow of hard intensity and/or current, for example 3m/s.
In embodiments of the present invention, in order to realize the successive operation of removing sand, can adopt the whole bag of tricks that slurries 80 or water are flowed, for example can use pump or other suction unit or utilize the potential energy of slurries 80 to make slurries 80, and make water carry the cassava particle then from exporting 73 outflows from 72 inflows that enter the mouth.Preferably, can control the velocity of flow of slurries 80 by pump.Especially relatively large to density cassava particle can prevent further that by accelerating flow velocity the cassava particle from precipitating.
Because therefore the relative open to the outside world in top of riffler 106 is convenient to monitoring, obtains the height of best flow velocity and outlet 73 with adjusting.
Obviously, described riffler also can be realized the enclosed operation of removing sand.But hands-off operation only limits to isolate the cassava particle that can swim in fully in the water.In closed when operation of removing sand, can make slurries 80 in riffler 106, leave standstill preset time so that the grains of sand are deposited to bottom 75 fully, make the Tapioca Starch that swims in the water derive riffler 106 then with current, similarly, in closed when operation of removing sand, also can in riffler 106, jet apparatus be set, thereby avoid the cassava particle to be subjected to the obstruction of the grains of sand and deposit to sedimentary tiny foreign material 82, cause waste.
Below with reference to Fig. 5 to Figure 14, the setting of knot screen is described in detail.
