An outlet pipe 32 is provided in the boiling pond 3；The outlet pipe 32 is through one first suction pump 33 and a triple valve 34 connections；The first outlet of the triple valve 34 is connected to drainpipe 35；The second outlet of the triple valve 34 is connected to black liquor Scratch pool 36；The leakage fluid dram 361 of the black liquor scratch pool 36 and a black liquor storage pool（It is not shown）Connection；The black liquor scratch pool Liquid spill-way 37 be connected to alkali liquor preparing pond 38；The alkali liquor preparing pond 38 is provided with the second suction pump 39, and described second takes out The water outlet of water pump 39 is connect with by feed liquor supervisor 40 with the boiling pond 3；Preferably, may be used also in the alkali liquor preparing pond 38 Stirring motor 41 is arranged, in favor of being stirred when allotment.First suction pump 33, triple valve 34, black liquor scratch pool 36, black liquor Storage pool, alkali liquor preparing pond 38, the second suction pump 39 are all set in below the road surface.
After the boiling frame equipped with broken bamboo is located in boiling pond, 40 are responsible for by cooking liquor by feed liquor（Cooking liquor includes alkali Liquid or black liquor, the basicity in black liquor is high, and impurity is few can then to be recycled, and black liquor neutral and alkali degree is low, and impurity height then cannot be again It uses）It pours into boiling pond, boiling pond carries out boiling to the bamboo in boiling frame.Cooking liquor completely impregnates bamboo in this way Boiling is not in that cooking liquor sprays non-uniform situation, and the broken bamboo chip that such boiling comes out is integrally of good quality, i.e., is all white Color is not in black, improves the broken bamboo quality for making paper pulp.
It is noted that the present invention is provided with black liquor scratch pool and alkali liquor preparing pond；By opening the first suction pump, together Black liquor is pumped into black liquor scratch pool by the first suction pump by Shi Kaiqi triple valve, then passes through screw drive for the boiling frame It raises up, staff can be according to the concentration and basicity of black liquor, to determine whether the black liquor given off is carried out weight It is new to utilize, it is not available, then black liquor is discharged by leakage fluid dram, it is available then black liquor is passed through into black liquor scratch pool and is flowed into Alkali liquor preparing pond recycles after allotment, greatly reduces the generation of black liquor.
In the present invention, the motor 63 is fixed on wall, or is fixed on 6 lower section of support frame as described above.Such motor 63 preferably can drive screw rod to be rotated；The boiling pond 3 is rectangular.
In addition, in the present invention, a hand winch 25 is provided at left and right sides of the top of the boiling frame 2, it is described Hand winch 25 is connect by traction rope 44 with the openable and closable discharging cover board 22, which can drive discharging cover board 22 carry out lifting operation up and down, and the openable and closable discharging cover board 22 is locked together on boiling frame 2 by mechanical lock 8, the machinery Lock 8 includes the limit assembly 81 of multiple groups, and the limit assembly 81 includes limit buckle 811 and limited post 812；The limit buckle 811 It is fixed on the side wall of the boiling frame 2, one end of the limited post 812 is hingedly set to the openable and closable discharging cover board 22 Side wall, the position of the limit buckle 811 is corresponding with the limited post 812；The other end of limited post 812 is laterally vertically arranged After having a cross bar 813, the limited post 812 to be buckled in the limit buckle 811, sealed fixation is carried out by the cross bar 813.? It can also be carried out using other modes in practical application sealed.
The alkali liquor preparing pond 38 includes inner wall 381 and outer wall 382, forms one between the inner wall 381 and outer wall 382 Hollow cavity 383 is provided with an air inlet pipe 384 on the upside of the outer wall 382 in the alkali liquor preparing pond 38, the alkali liquor preparing pond 38 An escape pipe 385 is provided on the downside of outer wall 382, the air inlet pipe 384 can enter in hot gas to hollow cavity 383, so that hot gas Black liquor in alkali liquor preparing pond 38 is preheated.Boiling pond, energy are entered after can directly preheating using black liquor again in this way Improve boiling efficiency.
In short, the present invention is provided with black liquor scratch pool and alkali liquor preparing pond；By opening the first suction pump, while opening three Black liquor is pumped into black liquor scratch pool by the first suction pump by port valve, is then raised up the boiling frame by screw drive, Staff can be according to the concentration and basicity of black liquor, to determine whether the black liquor given off is re-used, no It is available, then black liquor is discharged by leakage fluid dram, it is available then black liquor is flowed into alkali liquor preparing by black liquor scratch pool Pond recycles after allotment, greatly reduces the generation of black liquor.
The foregoing is merely presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with Modification, is all covered by the present invention.
