Technical Field

[0001] The present invention relates to a pulper and a pulping method thereof, in particular to a pulper for pulp production and a pulping method thereof, belonging to the technical field of pulpers. Background Art

[0002] A pulper is mainly used for pulping pulp boards, waste books, waste cartons, etc. The structure of a pulper generally includes a pulping cylinder, pulping knives, a rotating shaft, and a motor. Its working principle is: start the motor, the pulping knives start to rotate, the pulp enters the pulping cylinder from the feed port, and the pulp is pulped and discharged by the pulping knives.

[0003] However, in traditional pulpers, the crushing and stirring structures are usually set together. If the crushing is not thorough, the pulp may wind around the pulping knives after adding water, which will affect the stirring efficiency. Moreover, different papers cannot be effectively separated, resulting in a greatly reduced range of use.

[0004] Therefore, it is urgent to improve the pulper to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a pulper for pulp production and a pulping method thereof. The paper is pre-cut under the action of a crushing roller structure, re-crushed under the action of a crushing wheel structure, and the crushed paper scraps are pulped under the action of a pulp pounding mechanism. The crushing and stirring are separated, greatly improving the crushing efficiency. At the same time, after one kind of paper is crushed, it does not affect the stirring of the previous kind of pulp, greatly expanding the range of use.

[0006] To achieve the above purpose, the main technical solutions adopted by the present invention include:

[0007] A pulper for pulp production includes a pulper body. A crushing box and a stirring box are provided inside the pulper body. A crushing roller structure is arranged inside the crushing box. A lifting mechanism is slidably arranged below the crushing roller structure. A crushing wheel structure is arranged on the upper side of the lifting mechanism;

[0008] A pulp pounding mechanism is connected to the inside of the stirring box through a water adding member. The pulp pounding mechanism is fixedly arranged on the lower side of the water adding member. An isolating member is arranged between the crushing box and the stirring box. A sealing plate telescopic rod is arranged in the upper middle part of the isolating member. The sealing plate telescopic rod is used to isolate the crushing box and the stirring box;

[0009] Through the above technical solutions, the present invention can classify the papers and then sequentially add them into the interior of the crushing box. Under the action of the crushing roller structure inside the crushing box, the papers are pre-cut, and then under the action of the crushing wheel structure, the crushed papers are crushed again, and the crushed paper scraps are discharged into the interior of the stirring box. The paper scraps are slurried by adding water through the water adding member and the pulping mechanism inside the stirring box, and are thoroughly stirred under the action of the rotating pulping structure. The crushing box and the stirring box are separated to separate crushing and stirring, greatly improving the crushing efficiency. At the same time, after one type of paper is crushed, it does not affect the stirring of the previous type of pulp.

[0010] Preferably, the crushing roller structure includes a first crushing roller and a second crushing roller. One end of the first crushing roller is connected with a first driven gear, and one end of the second crushing roller is connected with a second driven gear. The second driven gear and the first driven gear are arranged on the outer side of the pulp grinder body and are meshed. Crushing teeth are fixedly arranged on the outer sides of both the first crushing roller and the second crushing roller. The crushing teeth on the first crushing roller and the crushing teeth on the second crushing roller are arranged in an interlaced manner. The papers are placed between the first crushing roller and the second crushing roller of the crushing roller structure through the feeding port, and the papers are cut and crushed by the interlaced crushing teeth.

[0011] A driving member is meshed with the first driven gear. The driving member is provided with a driving gear and a driven pulley. The driving gear is meshed with the first driven gear, and the driving gear is used to rotate the first driven gear. The driven pulley is connected with a driving motor through a belt. The driving motor is fixedly arranged on the upper side of the pulp grinder body. During the crushing process, the rotation of the driving motor drives the rotation of the driving member through the belt. The driving gear on the driving member drives the first driven gear on the first crushing roller and the second driven gear on the second crushing roller to rotate towards each other. The mutual rotation of the first driven gear and the second driven gear can cause the papers to be crushed under the action of the crushing teeth, greatly improving the crushing efficiency.

[0012] Preferably, the lifting mechanism includes a telescopic rod and a lifting table fixedly arranged at the output end of the telescopic rod. The crushing wheel structure includes a crushing motor, a crushing wheel and a chip discharging wheel. A motor chamber is formed inside the lifting table. The crushing motor is fixedly arranged inside the motor chamber. The output end of the crushing motor is connected with an output shaft. The output shaft penetrates through the lifting table. Both the crushing wheel and the chip discharging wheel are fixedly arranged on the output shaft, and the chip discharging wheel is fixedly arranged below the crushing wheel. The lifting table is used to vertically push the crushing wheel structure.

[0013] Through the above technical solutions, before crushing, the lifting table on the lifting mechanism slides to the bottom of the crushing box. Therefore, the crushed paper scraps can be crushed again by the crushing wheel structure on the lifting mechanism. The two chip discharging wheels can crush the paper on one side, improving the uniformity of crushing. Through the vertical cutting of the crushing roller structure and the horizontal cutting of the chip discharging wheels, the adhesion of paper scraps to the mixer can be prevented.

[0014] Preferably, the upper end of the water adding member is fixedly arranged on the upper side surface inside the mixing box. A water pump is connected inside the water adding member through a water pipe. The water pump is fixedly arranged on one side of the driving motor. A plurality of water spray heads are arranged on the lower side surface of the water adding member. The water spray heads are communicated with the water pump. The paper scraps inside the mixing box are watered through the water adding member connected to the water pump. Water is sprayed into the interior of the pulp through the water spray heads on the lower side surface of the water adding member.

[0015] Preferably, the pulp pounding mechanism is fixedly arranged in the middle of the lower end surface of the water adding member through a double-output shaft connecting member. The pulp pounding mechanism includes a double-output shaft motor and a heavy hammer. Output ends at both ends of the double-output shaft motor are connected with special-shaped cams. One end of the special-shaped cam away from the double-output shaft motor is rotationally connected with the heavy hammer through a connecting rod. The upper end of the heavy hammer is fixedly provided with a heavy hammer connecting member. The heavy hammer connecting member is rotationally connected with the connecting rod through a rivet. Heavy hammer convex points are fixedly arranged on the outer side surface of the heavy hammer;

[0016] Through the above technical solutions, the double-output shaft motor connected through the double-output shaft connecting member drives the rotation of the special-shaped cam when powered on. During the rotation of the special-shaped cam, the heavy hammer below the connecting rod is driven to stir and pound the pulp. Compared with the traditional stirring structure, the efficiency of pounding and stirring the pulp is greatly improved, and the uniformity of the pulp can also be fully improved.

[0017] Preferably, a rotating pulp crushing structure is fixedly arranged below the pulp pounding mechanism. The rotating pulp crushing structure includes a pulp crushing motor and a rotating plate. The pulp crushing motor is fixedly arranged at the bottom of the inner side surface of the mixing box. The output end of the pulp crushing motor is fixedly connected with the rotating plate. A plurality of pulp crushing plate convex points are fixedly arranged on the upper side surface of the rotating plate. Under the action of the pulp crushing motor of the pulp crushing structure, the rotating plate rotates, greatly improving the efficiency of pulp crushing in cooperation with the heavy hammer. At the same time, the cooperation between the heavy hammer convex points on the heavy hammer and the pulp crushing plate convex points on the upper side surface of the rotating plate makes the crushing effect more obvious.

[0018] Preferably, a sealing plate groove is formed inside the separator. The sealing plate telescopic rod is fixedly arranged inside the sealing plate groove. The output end of the sealing plate telescopic rod is connected with a sealing plate. The sealing plate is vertically slidably arranged inside the sealing plate groove. A waterproof layer is fixedly arranged on the outer side surface of the sealing plate. After the crushing wheel structure on the lifting mechanism crushes the paper again, the sealing plate telescopic rod on the separator seals the crushing box and the stirring box. Therefore, the stirring of the pulp is not affected during the crushing process.

[0019] Preferably, a discharge port is formed on one side surface of the stirring box. A discharge door body is rotatably arranged inside the discharge port through a rivet. The upper end of the discharge door body is fixedly connected with the stirring box through a door body bolt. By opening the door body bolt on the discharge door body to open the discharge door body, on the one hand, it is convenient to improve the discharge efficiency, and on the other hand, it improves the sealing performance of the stirring box. An inlet is formed on the upper end surface of the crushing box. The inlet is communicated with the crushing box.

[0020] A viewing window groove is formed on the stirring box. A viewing window is fixedly arranged inside the viewing window groove. The situation inside the stirring box can be observed at any time through the viewing window on the viewing window groove, improving the convenience of use.

[0021] A pulping method for a pulper used in pulp production includes the following steps:

[0022] Step 1: First, place various papers inside the crushing roller structure through the inlet on the pulper body, and pre-crush the papers.

[0023] Step 2: The paper is further crushed under the action of the crushing wheel structure. Specifically before crushing, it includes:

[0024] a. First, slide the sealing plate inside the separator downward through the sealing plate telescopic rod to isolate the crushing box and the stirring box.

[0025] b. Before complete crushing, the lifting platform on the lifting mechanism slides to the bottom of the crushing box, and the shredded paper is further crushed by the crushing wheel on the crushing wheel structure.

[0026] c. After crushing, lift the lifting platform upward, then open the sealing plate, and the crushed paper scraps are thrown into the inside of the stirring box by the chip removal wheel on the crushing wheel structure.

[0027] Step 3: Add water to the inside of the stirring box through the water adding member, and stir the pulp through the beating mechanism and the rotary pulping structure.

[0028] Step 4: After stirring, take out the pulp through the discharge door body.

[0029] The present invention has at least the following beneficial effects:

[0030] 1. The paper is pre-cut under the action of the crushing roller structure and then re-crushed under the action of the crushing wheel structure. The crushed paper scraps are pulped under the action of the pulping mechanism. The crushing and stirring are separated, greatly improving the crushing efficiency. At the same time, after one type of paper is crushed, it does not affect the stirring of the previous pulp, greatly expanding the scope of use.

[0043] The following will detail the implementation manners of the present application in conjunction with the drawings and embodiments, so as to fully understand the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects and implement accordingly.

[0044] As Figures 1-9 shown, the pulper for pulp production provided in this embodiment includes a pulper body 1. A crushing box 101 and a stirring box 102 are arranged inside the pulper body 1. A crushing roller structure 2 is arranged inside the crushing box 101. A lifting mechanism 6 is slidably arranged below the crushing roller structure 2. A crushing wheel structure 3 is arranged on the upper side surface of the lifting mechanism 6. A pulp pounding mechanism 4 is connected to the inside of the stirring box 102 through a water adding part 7. The pulp pounding mechanism 4 is fixedly arranged on the lower side surface of the water adding part 7. A separator 104 is arranged between the crushing box 101 and the stirring box 102. A sealing plate telescopic rod 9 is arranged in the upper middle part of the separator 104. The sealing plate telescopic rod 9 is used to isolate the crushing box 101 and the stirring box 102;

[0045] The present invention can classify the papers and then sequentially add them into the interior of the crushing box 101. Under the action of the crushing roller structure 2 inside the crushing box 101, the papers are pre-cut, and then under the action of the crushing wheel structure 3, the crushed papers are crushed again, and the crushed paper scraps are discharged into the interior of the stirring box 102. The paper scraps are slurried by adding water through the water adding member 7 inside the stirring box 102 and are slurried by the pulping mechanism 4, and are thoroughly stirred under the action of the rotating pulping structure 5. The crushing box 101 is separated from the stirring box 102 to separate crushing and stirring, greatly improving the crushing efficiency. At the same time, after one type of paper is crushed, it does not affect the stirring of the previous type of pulp.

[0046] Pre-crushing: As Figure 4 and Figure 5 shown, the crushing roller structure 2 includes a first crushing roller 201 and a second crushing roller 202. One end of the first crushing roller 201 is connected with a first driven gear 203, and one end of the second crushing roller 202 is connected with a second driven gear 204. The second driven gear 204 and the first driven gear 203 are arranged on the outer side surface of the pulping machine body 1 and are meshed and connected. Crushing teeth 205 are fixedly arranged on the outer side surfaces of both the first crushing roller 201 and the second crushing roller 202. The crushing teeth 205 on the first crushing roller 201 and the crushing teeth 205 on the second crushing roller 202 are arranged in an interlaced manner. The upper end surface of the crushing box 101 is provided with a feeding port 103, and the feeding port 103 is communicated with the crushing box 101. The papers are placed between the first crushing roller 201 and the second crushing roller 202 of the crushing roller structure 2 through the feeding port 103, and the papers are cut and crushed by the interlaced crushing teeth 205;

[0047] A driving member 8 is meshed and connected to the first driven gear 203. The driving member 8 is provided with a driving gear 801 and a driven pulley 802. The driving gear 801 is meshed and connected to the first driven gear 203, and the driving gear 801 is used for rotating the first driven gear 203. The driven pulley 802 is connected with a driving motor 10 through a belt, and the driving motor 10 is fixedly arranged on the upper side surface of the pulping machine body 1;

[0048] During the crushing process, the rotation of the driving motor 10 drives the rotation of the driving member 8 through the belt. The driving gear 801 on the driving member 8 drives the first driven gear 203 on the first crushing roller 201 and the second driven gear 204 on the second crushing roller 202 to rotate towards each other. The mutual rotation of the first driven gear 203 and the second driven gear 204 can cause the papers to be crushed under the action of the crushing teeth 205, greatly improving the crushing efficiency.

[0049] Re-crushing, as Figure 3As shown, the lifting mechanism 6 includes a telescopic rod 602 and a lifting platform 601 fixedly arranged at the output end of the telescopic rod 602. The crushing wheel structure 3 includes a crushing motor 301, a crushing wheel 302, and a chip discharging wheel 303. An electric motor chamber 603 is formed inside the lifting platform 601. The crushing motor 301 is fixedly arranged inside the electric motor chamber 603. The output end of the crushing motor 301 is connected with an output shaft 304. The output shaft 304 penetrates through the lifting platform 601. Both the crushing wheel 302 and the chip discharging wheel 303 are fixedly arranged on the output shaft 304, and the chip discharging wheel 303 is fixedly arranged below the crushing wheel 302. The lifting platform 601 is used for vertically pushing the crushing wheel structure 3;

[0050] Before crushing, the lifting platform 601 on the lifting mechanism 6 slides to the bottom of the crushing box 101. Therefore, the crushed paper scraps can be crushed again by the crushing wheel structure 3 on the lifting mechanism 6. The two chip discharging wheels 303 can crush the paper on one side, improving the uniformity of crushing. Through the vertical cutting of the crushing roller structure 2 and the horizontal cutting of the chip discharging wheels 303, it is possible to prevent the paper scraps from sticking to the mixer;

[0051] At the same time, as Figure 8 shown, a sealing plate groove 107 is formed inside the separator 104. The sealing plate telescopic rod 9 is fixedly arranged inside the sealing plate groove 107. The output end of the sealing plate telescopic rod 9 is connected with a sealing plate 901. The sealing plate 901 is vertically slidably arranged inside the sealing plate groove 107. A waterproof layer 902 is fixedly arranged on the outer side surface of the sealing plate 901. After the crushing wheel structure 3 on the lifting mechanism 6 crushes the paper again, the sealing plate telescopic rod 9 on the separator 104 seals the crushing box 101 and the mixing box 102. Therefore, the stirring of the pulp is not affected during the crushing process;

[0052] After the crushing is completed, the lifting platform 601 on the lifting mechanism 6 pushes the crushed paper scraps to the lower end of the sealing plate telescopic rod 9 through the telescopic rod 602, and then the sealing plate telescopic rod 9 is opened. The crushed paper scraps are thrown into the interior of the mixing box 102 by the chip discharging wheel 303 below the crushing wheel 302. The structure is simple, greatly improving the processing efficiency.

[0053] When the pulp is stirred, as Figure 1 shown, the upper end of the water adding member 7 is fixedly arranged on the upper side surface inside the mixing box 102. The interior of the water adding member 7 is connected with a water pump 11 through a water pipe. The water pump 11 is fixedly arranged on one side of the driving motor 10. A plurality of spray heads 701 are arranged on the lower side surface of the water adding member 7. The spray heads 701 are communicated with the water pump 11. Water is added to the paper scraps inside the mixing box 102 through the water adding member 7 connected with the water pump 11. The water is sprayed into the interior of the pulp through the spray heads 701 on the lower side surface of the water adding member 7.

[0054] When pulping, asFigure 6 and Figure 7 As shown in Figure 7 , the pulp pounding mechanism 4 is fixedly arranged in the middle of the lower end surface of the water adding member 7 through a double-output shaft connecting member 405. The pulp pounding mechanism 4 includes a double-output shaft motor 401 and a heavy hammer 403. Output ends at both ends of the double-output shaft motor 401 are connected with special-shaped cams 402. One end of the special-shaped cam 402 far away from the double-output shaft motor 401 is rotationally connected with the heavy hammer 403 through a connecting rod 404;

[0055] A heavy hammer connecting member 406 is fixedly arranged at the upper end of the heavy hammer 403. The heavy hammer connecting member 406 is rotationally connected with the connecting rod 404 through a rivet. Heavy hammer bumps 407 are fixedly arranged on the outer side surface of the heavy hammer 403.

[0056] When the double-output shaft motor 401 connected through the double-output shaft connecting member 405 is electrified, it drives the rotation of the special-shaped cam 402. During the rotation of the special-shaped cam 402, the heavy hammer 403 below the connecting rod 404 is driven to stir and pound the pulp. Compared with the traditional stirring structure, the efficiency of pounding and stirring the pulp is greatly improved, and the uniformity of the pulp can also be fully improved;

[0057] At the same time, as Figure 1 shown, a rotary pulp shredding structure 5 is fixedly arranged below the pulp pounding mechanism 4. The rotary pulp shredding structure 5 includes a pulp shredding motor 501 and a rotary plate 502;

[0058] The pulp shredding motor 501 is fixedly arranged at the bottom of the inner side surface of the stirring tank 102. The output end of the pulp shredding motor 501 is fixedly connected with the rotary plate 502. A plurality of pulp shredding plate bumps 503 are fixedly arranged on the upper side surface of the rotary plate 502;

[0059] Under the action of the pulp shredding motor 501 of the pulp shredding structure 5, the rotary plate 502 rotates, which greatly improves the efficiency of pulp shredding in cooperation with the heavy hammer 403. At the same time, the pulverizing effect is more obvious in cooperation with the heavy hammer bumps 407 on the heavy hammer 403 and the pulp shredding plate bumps 503 on the upper side surface of the rotary plate 502.

[0060] When discharging the pulp, as Figure 1 shown, a discharge port 105 is formed on one side surface of the stirring tank 102. A discharge door body 12 is rotationally arranged inside the discharge port 105 through a rivet. The upper end of the discharge door body 12 is fixedly connected with the stirring tank 102 through a door body bolt 13. By opening the door body bolt 13 on the discharge door body 12, the discharge door body 12 is opened. On the one hand, it is convenient to improve the discharge efficiency, and on the other hand, it improves the sealing performance of the stirring tank 102;

[0061] At the same time, a visual window groove 106 is formed on the stirring tank 102. A visual window 14 is fixedly arranged inside the visual window groove 106. The situation inside the stirring tank 102 can be observed at any time through the visual window 14 on the visual window groove 106, which improves the convenience of use.
