Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, for caustic soda, the concentrated alkali lye distribution device of sheet alkali, comprise: feed-pipe 1, feed-pipe 1 stretches into downwards in distribution box 2, described distribution box 2 is positioned at airtight charging casing 3, the both sides of distribution box 2 offer respectively the overflow port 4 of same size, on the overflow port 4 of every side, be provided with alkali lye is guided to the diversion trench 19 in this side Material collecting box for harvesting.The effect of diversion trench 19 is to prevent that alkali lye is along the outer wall trickling of distribution box 2.Bottom in the charging casing 3 of distribution box 2 belows is provided with two open tops, and the Material collecting box for harvesting mutually cutting off, be respectively the first Material collecting box for harvesting 5 and the second Material collecting box for harvesting 6, the bottom of two Material collecting box for harvesting is respectively arranged with the discharge port 7 for discharging, a minor axis expansion bearing is passed through respectively in charging casing 3 in the both sides of distribution box 2, a wherein minor axis of distribution box 2 is fixedly connected with cross bar 8, the protruding charging casing 3 of cross bar 8, when distribution box 2 is positioned at vertical state, alkali lye in distribution box 2 can evenly overflow respectively from the overflow port 4 of both sides, and evenly flow into respectively in first Material collecting box for harvesting 5 and the second Material collecting box for harvesting 6 of distribution box 2 belows, cross bar 8 can drive distribution box 2 rotation, and the top of distribution box 2 is tilted to the Material collecting box for harvesting of its below respectively, and when a Material collecting box for harvesting tilts wherein at distribution box 2 tops, the alkali lye in distribution box 2 can flow out in this Material collecting box for harvesting from the overflow port 4 of a corresponding side, on cross bar 8 outside charging casing 3, be connected with and drive rotating driving device that cross bar 8 rotates and for the locking gear of fixed transverse rod.In the present embodiment, described rotating driving device and the structure of locking gear are: in the outer end of cross bar 8, be fixedly connected with montant 9, on montant 9, be provided with handle 10, on handle 10, be provided with lock(ing) bolt 11, be positioned on the bracing frame 12 of cross bar 8 outer ends and be provided with back up pad 13, in back up pad 13, be provided with a left side, in, right three bolts hole 14, 15, 16 and left, right two blocks 17, 18, two in left and right blocks 17 of montant 9, while swinging between 18, can drive the top of distribution box 2 to the first Material collecting box for harvesting 5 and second Material collecting box for harvesting 6 of its below, to tilt respectively, thereby the alkali lye in distribution box 2 is flowed out in corresponding Material collecting box for harvesting from the overflow port 4 of a corresponding side.In the time of on block 17 on the left of montant 9 is resisted against, lock(ing) bolt 11 on handle 10 can be locked in the bolt hole 14 in left side, now distribution box 2 is locked in the state that its top tilts to the second Material collecting box for harvesting 6, and the alkali lye in distribution box 2 can flow out in the second Material collecting box for harvesting 6 from the overflow port 4 of a corresponding side; When montant 9 is resisted against on the block 18 on right side, lock(ing) bolt 11 on handle 10 can be locked in the bolt hole 16 on right side, now distribution box 2 is locked in the state that its top tilts to the first Material collecting box for harvesting 5, and the alkali lye in distribution box 2 can flow out in the first Material collecting box for harvesting 5 from the overflow port 4 of this side; When the bolt hole 15 of the lock(ing) bolt 11 on handle 10 in the middle of being locked at is interior, distribution box 2 is locked in vertical state, and now the alkali lye in distribution box 2 can evenly flow out from the overflow port of both sides.
Principle of work of the present utility model is as follows: when needs are during simultaneously to the first Material collecting box for harvesting 5 and the second Material collecting box for harvesting 6 interior charging, in bolt hole 15 in the middle of only the lock(ing) bolt on handle 10 11 need being locked at, now distribution box 2 is locked in vertical state, alkali lye in feed-pipe 1 enters distribution box 2 can overflow respectively uniformly from the overflow port 4 of both sides simultaneously like this, and evenly flow into respectively in first Material collecting box for harvesting 5 and the second Material collecting box for harvesting 6 of distribution box 2 belows, can guarantee like this to flow into the first Material collecting box for harvesting 5 identical with the amount of the second Material collecting box for harvesting 6 interior alkali lye, thereby effectively guaranteed that alkali lye can divide equally to the first Material collecting box for harvesting 5 and the second Material collecting box for harvesting 6.When only need to be in a Material collecting box for harvesting during charging, the present embodiment be take and described to the interior charging of the first Material collecting box for harvesting 5 as example.Handle 10 turns right, thereby being swung, montant 9 make cross bar 8 drive distribution box 2 to rotate to the right, thereby the top of distribution box 2 is tilted to the first Material collecting box for harvesting 5, when montant 9 is resisted against on the block 18 on right side, lock(ing) bolt on handle 10 11 is locked in the bolt hole 16 on right side, now distribution box 2 is locked in the state that its top tilts to the first Material collecting box for harvesting 5, and now the alkali lye in distribution box 2 can be from the overflow port 4 in left side in diversion trench 19 flows into the first Material collecting box for harvesting 5.To the principle of work of the second Material collecting box for harvesting 6 interior chargings, with similar to the principle of work of the first Material collecting box for harvesting 5 interior chargings, do not repeat them here.Above-mentioned distribution device simple and practical, can not only all assign to alkali lye in two Material collecting box for harvesting, can also be as required charging in a Material collecting box for harvesting wherein, and operation and control all is very conveniently worked also very reliable under worst hot case.
