Description

Technical Field

[0001] The present invention belongs to the field of wastewater treatment, and specifically relates to a papermaking wastewater treatment device for waste paper recycling. Background Art

[0002] The process of waste paper recycling papermaking usually includes processes such as pulping, slag removal, screening, purification, bleaching, and papermaking. A large amount of wastewater containing pollutants such as pulp fibers, chemical agents, suspended solids, and organic substances is generated in these processes, and these wastewaters need to be treated to remove pollutants, recover useful substances, and make the wastewater meet the discharge standards.

[0003] The patent with the publication number CN215627286U discloses a wastewater treatment device for waste paper recycling papermaking, including a filtration box. A plurality of mounting holes are provided on the inner wall of the filtration box, and a filtration slide plate slides in each of the plurality of mounting holes. A connecting pipe is fixedly installed at the lower end of the filtration box, and one end of the connecting pipe away from the filtration box is fixedly installed with a purification box. A medicine storage box is fixedly installed at the upper end of the purification box, a fixing frame is fixedly installed at the upper end of the medicine storage box, a servo motor is fixedly installed at the upper end of the fixing frame, and a medicine inlet block is fixedly installed at the output end of the servo motor. It is convenient to filter out the pulp in the wastewater, and it is convenient to take out the filtration slide plate storing the pulp, and it does not affect the continuous filtration of the pulp by the device, thereby improving the utilization rate of waste paper. At the same time, the oxidant is continuously and widely added into the purification box through the stirring pipe for purification, and the reaction between the oxidant and the wastewater is accelerated by stirring, thereby improving the wastewater treatment efficiency.

[0004] However, the above technical solution still has the following deficiencies in the actual application process: After the wastewater is preliminarily filtered, it will enter the purification box. Then, solid medicine is added into the medicine storage box, and the solid medicine enters the purification box through the medicine inlet pipe, and then the wastewater and the solid medicine are stirred to achieve the purpose of purifying the wastewater. However, when the solid medicine is added to the wastewater, the adding position is relatively single, and the solid medicine will concentrate in a local part of the inner cavity of the purification box, so it takes a longer stirring time to evenly mix the wastewater and the solid medicine, thereby affecting the wastewater purification efficiency. Moreover, when the solid medicine is added to the purification box, all the solid medicine will enter the purification box through the medicine inlet pipe at one time, which will cause the medicine concentration to rise rapidly, and then gradually decrease due to the continuous inflow of wastewater, resulting in large fluctuations in the medicine concentration, making it difficult to ensure the continuous treatment effect and easily causing waste of medicine.

[0016] The beneficial effects of the present invention are as follows: 1. For the papermaking wastewater treatment equipment for waste paper recycling described in the present invention, by using the variable-diameter auxiliary medicine adding assembly, multiple medicine storage shells can move regularly above the purification tank, and the medicine can be evenly added to each area inside the purification tank. Then, the stirring blades are used to stir the medicine and the wastewater, and the medicine and the wastewater can be mixed faster, thereby improving the purification efficiency of the wastewater. In addition, the adding time and the single addition amount of the medicine can be controlled according to the amount of wastewater and the purification situation inside the purification tank, avoiding the situation that the concentration of the medicine rises rapidly when all the solid medicine enters the purification tank at one time, and then the concentration of the medicine decreases due to the continuous addition of wastewater, resulting in large fluctuations in the medicine concentration, making it difficult to ensure the continuous treatment effect and easily causing waste of the medicine. Moreover, compared with the traditional method of controlling the medicine adding time by using a valve, this method can ensure that the amount of medicine added each time is the same as the volume of the medicine receiving cavity, and there will be no deviation in the amount of medicine added each time due to the medicine flow rate problem, and the amount of medicine added can be controlled more accurately.

[0017] 2. The papermaking wastewater treatment equipment for waste paper recycling according to the present invention utilizes a medicine receiving cavity and a cooperative cutting assembly. During the medicine receiving process, the blade continuously moves and cuts the medicine in the medicine receiving cavity and at the upper opening, thereby promoting the movement of the medicine and effectively avoiding the situation where the medicine amount is affected due to the medicine getting stuck at the opening. Moreover, since the rotating shell makes a circular motion, after the medicine receiving cavity receives the medicine, during the rotation of the rotating shell, the medicine in the medicine receiving cavity also moves. At the same time, the blade continuously cuts the medicine, and the agglomerated medicine in the medicine receiving cavity can be evenly cut, avoiding the situation where the reaction effect between the subsequent medicine and the wastewater is affected due to the addition of the agglomerated medicine into the wastewater.

[0018] 3. The papermaking wastewater treatment equipment for waste paper recycling according to the present invention utilizes a feeding auxiliary assembly, which can adaptively adjust the pressing plate one and the pressing plate two according to the angle and length of the hose. During the process of the medicine moving through the hose to the medicine storage shell, the pressing plate one and the pressing plate two move to press the bottom of the hose, and thus the movement of the medicine in the hose can be promoted by pushing the bottom of the hose, thereby avoiding the situation where the medicine is stuck inside the hose during its movement, which in turn affects the normal addition of the medicine.

Openings 22 are arranged in the middle of the upper and lower sides of the medicine storage shell 20, and the upper opening 22 is communicated with the end of the hose 19.

[0024] In this embodiment, as Figures 3 - 7 shown, a stirring shaft 24 is rotatably arranged at the bottom of the inner cavity of the purification tank 5. A plurality of stirring blades 25 are fixedly connected to the stirring shaft 24. The middle part of the lower end face of the purification tank 5 is fixedly connected with a second motor 23. The output end of the second motor 23 is fixedly connected to the lower end of the stirring shaft 24.

[0025] A first gear ring 13 is sleeved and fixedly connected to the upper side of the medicine storage cylinder 8. A first gear 12 is rotatably arranged on one side of the upper end face of the mounting frame 7. The first gear 12 meshes with the tooth blocks on the outer ring of the first gear ring 13. A third motor 36 is fixedly connected to one side of the upper end of the mounting frame 7. The output end of the third motor 36 is fixedly connected to the first gear 12.

[0026] A second gear ring 15 is rotatably arranged on the upper end face of the mounting ring 14. One end of a first connecting rod 16 is fixedly connected with a third gear 38. The third gear 38 is rotatably arranged on the mounting ring 14. The third gear 38 meshes with the tooth blocks on the outer ring of the second gear ring 15.

[0028] A first cylinder 30 is fixedly connected to one side of the inner cavity of the rotating shell 27. The piston end of the first cylinder 30 is fixedly connected with a push plate 31. The push plate 31 is fixedly connected to one side of the soft pad 26.

[0029] Specifically, in the prior art, after the wastewater is preliminarily filtered, it will enter the purification tank 5. Then, solid medicine is added to the medicine storage tank. The solid medicine enters the purification tank 5 through the medicine inlet pipe, and then the wastewater and the solid medicine are stirred to achieve the purpose of purifying the wastewater. However, when the solid medicine is added to the wastewater, the adding position is relatively single, and the solid medicine will be concentrated in a local part of the inner cavity of the purification tank 5. Then, a longer stirring time is required to evenly mix the wastewater and the solid medicine, thus affecting the wastewater purification efficiency. Moreover, when the solid medicine is added to the purification tank 5, all the solid medicine will enter the purification tank 5 through the medicine inlet pipe at one time, which will cause the medicine concentration to rise rapidly and then gradually decrease due to the continuous inflow of wastewater, resulting in a large fluctuation in the medicine concentration, making it difficult to ensure the continuous treatment effect and easy to cause waste of the medicine.

[0030] Therefore, to solve the above problems, when this embodiment is in use, the water inlet pipe 3 is communicated with the wastewater discharge pipe. The wastewater enters the filter tank 2 through the water inlet pipe 3. The coarse filter plate 9, the fine filter plate 11, and the medium filter plate 10 filter the pulp particles and tiny impurities in the wastewater. Moreover, this hierarchical filtering method can more accurately intercept the pulp and impurities with different particle sizes, greatly improving the filtering accuracy and efficiency, thereby reducing the pulp residue in the wastewater and being beneficial to improving the subsequent purification effect.

[0031] The filtered wastewater enters the purification tank 5 through the connecting pipe 4. Then, the medicament is added into the medicine storage cylinder 8. The medicament reaches the upper opening 22 of the medicine storage shell 20 through each hose 19. At this time, the medicine receiving cavity formed by the cooperation of the soft pad 26 and the rotating shell 27 is not aligned with the upper opening 22. Therefore, the medicament will only fall on the outer wall of the rotating shell 27. Then, the motor one 21 drives the rotating shell 27 to rotate until the medicine receiving cavity is aligned with the upper opening 22, and then the medicament will fall into the medicine receiving cavity. Then, the rotating shell 27 continues to rotate. The medicament in the medicine receiving cavity will move along with the rotating shell 27, while the medicament not in the medicine receiving cavity still stays at the upper opening 22. Since the edge of the medicine receiving cavity fits with the inner wall of the medicine storage shell 20 when the rotating shell 27 rotates, the medicine receiving cavity is closed and the medicament will not flow out of the medicine receiving cavity. When the medicine receiving cavity moves to the lower opening, the medicament falls into the purification tank 5. At the same time, the motor three 36 drives the gear one 12 to rotate, so that the gear ring one 13 and the medicine storage cylinder 8 rotate simultaneously, and then multiple medicine storage shells 20 simultaneously perform circular motions. Moreover, the motor four 37 drives the gear three 38 and the connecting rod one 16 on one side to rotate, so that the gear ring two 15 rotates on the mounting ring 14. Under the transmission of the gear three 38 and the gear ring two 15, multiple connecting rods one 16 and connecting rods two 17 rotate simultaneously to adjust the distance between the medicine storage shell 20 and the medicine storage cylinder 8, and the hose 19 is stretched. Through the above operations, the medicine storage shell 20 regularly moves above the purification tank 5, and the medicament will be evenly added to each area inside the purification tank 5. At this time, the motor two 23 drives the stirring shaft 24 to rotate, and the stirring blades 25 are used to stir the medicament and the wastewater, so that the medicament and the wastewater will be mixed faster, thereby improving the purification efficiency of the wastewater; Moreover, since the soft pad 26 is elastic, the soft pad 26 can be stretched by driving the push plate 31 to move through the cylinder one 30, thereby adjusting the volume of the medicine receiving cavity. At the same time, by controlling the rotation speed of the rotating shell 27, the timing and the single addition amount of the medicament can be controlled according to the amount and purification situation of the wastewater inside the purification tank 5, avoiding the situation that the concentration of the medicament rapidly increases when all the solid medicament enters the purification tank 5 at one time, and then the concentration of the medicament decreases due to the continuous addition of the wastewater, resulting in a large fluctuation in the concentration of the medicament, making it difficult to ensure the continuous treatment effect and easily causing waste of the medicament; When the wastewater is treated in the purification tank 5, the valve on the water outlet pipe 6 can be opened to discharge the treated wastewater.

[0032] In this embodiment, as Figure 7 、 Figure 8 、 Figure 10 shown, a cutting assembly in cooperative connection with the medicine receiving cavity is further arranged inside the rotating shell 27; The medicine receiving cavity cooperative cutting assembly includes connecting plates 29 slidably connected to both sides of the rotating shell 27. One side of the connecting plate 29 is fixedly connected with a blade 28, and the blade 28 is located inside the medicine receiving cavity.

[0033] One end of the connecting plate 29 is fixedly connected with a guide post 48. On both sides of the inner cavity of the rotating shell 27, a chute rod 35 is rotatably arranged. The guide post 48 is inserted into the chute of the chute rod 35 and is slidably connected thereto. One side of the lower end of the chute rod 35 is fixedly connected with a second gear 34. The second gear 34 is rotatably arranged in the inner cavity of the rotating shell 27. One side of the inner cavity of the rotating shell 27 is fixedly connected with a sliding post 46. The sliding post 46 is slidably connected with a rack bar 33. The tooth blocks on both sides of the rack bar 33 are meshed with the second gear 34. An eccentric block 32 is rotatably arranged on one side of the inner cavity of the rotating shell 27. The eccentric block 32 is in contact with one side of the rack bar 33. One side of the inner cavity of the rotating shell 27 is fixedly connected with a seventh motor 45. The output end of the seventh motor 45 is fixedly connected with the eccentric block 32. A spring 47 is sleeved on one side of the sliding post 46. One end of the spring 47 is fixedly connected with one side of the inner cavity of the rotating shell 27, and the other end is fixedly connected with one side of the rack bar 33.

[0034] Specifically, in the above embodiment, although the medicine receiving cavity can be used to receive the medicine, however, since the medicine is solid, the phenomenon of medicine caking may occur. This will not only cause the medicine to get stuck at the opening 22 during medicine receiving in the medicine receiving cavity, affecting the amount of medicine received, but also affect the subsequent reaction effect between the medicine and the wastewater. Therefore, to solve the above problems, during the use of this embodiment, when the medicine receiving cavity is receiving medicine, the seventh motor 45 drives the eccentric block 32 to continuously rotate. The eccentric block 32 continuously presses the rack bar 33, causing the rack bar 33 to slide on the sliding post 46 and reset under the action of the spring 47. Then the rack bar 33 moves up and down reciprocally, causing the second gears 34 and the chute rods 35 on both sides to also rotate reciprocally. Then, through the cooperation of the chute rod 35 and the guide post 48, the connecting plate 29 slides reciprocally inside the rotating shell 27, and the blade 28 will continuously move and cut the medicine in the medicine receiving cavity and at the upper opening 22, thereby promoting the movement of the medicine and effectively avoiding the situation that the amount of medicine received is affected due to the medicine getting stuck at the opening 22. And, since the rotating shell 27 makes a circular motion, after the medicine receiving cavity receives the medicine, during the rotation of the rotating shell 27, the medicine in the medicine receiving cavity will also move. At the same time, the blade 28 continuously cuts the caked medicine, avoiding the situation that the subsequent reaction effect between the medicine and the wastewater is affected due to the caked medicine being added to the wastewater.

[0035] In this embodiment, as Figure 5 and Figure 9 shown, multiple groups of blanking auxiliary components are also arranged at the bottom of the medicine storage cylinder 8; The blanking auxiliary assembly includes a second cylinder 39 rotatably arranged at the bottom of the medicine storage cylinder 8. A first extrusion plate 41 is fixedly connected to the piston end of the second cylinder 39. A second extrusion plate 42 is inserted and slidably connected to the inner side of the first extrusion plate 41.

[0036] A plurality of fifth motors 40 are fixedly connected to the lower end surface of the medicine storage cylinder 8. The output end of the fifth motor 40 is fixedly connected to one side of the second cylinder 39. A threaded rod 44 is threadedly connected to one side of the second extrusion plate 42. One end of the threaded rod 44 is rotatably arranged on the first extrusion plate 41. A sixth motor 43 is fixedly connected to one side of the first extrusion plate 41. The output end of the sixth motor 43 is fixedly connected to one end of the threaded rod 44.

[0037] Specifically, in the above embodiment, although the medicine adding orientation can be controlled by adjusting the distance between the medicine storage shell 20 and the medicine storage cylinder 8, however, this will cause the angle of the hose 19 to change. Moreover, the farther the distance between the medicine storage shell 20 and the medicine storage cylinder 8 is, the closer the hose 19 will be to the horizontal. When the medicine moves in the hose 19, it is easy to get stuck inside the hose 19, thus affecting the normal addition of the medicine. Therefore, to solve the above problems, when in use in this embodiment, whenever the length of the hose 19 is adjusted, the fifth motor 40 and the sixth motor 43 are started. The fifth motor 40 drives the second cylinder 39 to rotate, and the angles of the first extrusion plate 41 and the second extrusion plate 42 can be adjusted to make the first extrusion plate 41 and the second extrusion plate 42 parallel to the hose 19. The sixth motor 43 drives the threaded rod 44 to rotate, and the second extrusion plate 42 can slide inside the first extrusion plate 41 to adjust the total length of the first extrusion plate 41 and the second extrusion plate 42 to be equal to the length of the hose 19. When the medicine moves through the hose 19 to the medicine storage shell 20, the second cylinder 39 drives the first extrusion plate 41 and the second extrusion plate 42 to move, and the bottom of the hose 19 is extruded, so as to promote the movement of the medicine in the hose 19 by pushing the bottom of the hose 19, thereby avoiding the situation that the medicine gets stuck inside the hose 19 when moving in the hose 19, which in turn affects the normal addition of the medicine.

[0038] Working principle: Connect the water inlet pipe 3 with the waste water discharge pipe. The waste water enters the filter box 2 through the water inlet pipe 3. The coarse filter plate 9, the fine filter plate 11, and the medium filter plate 10 filter the pulp particles and tiny impurities in the waste water. Moreover, this hierarchical filtering method can intercept pulp and impurities with different particle sizes more precisely, greatly improving the filtering accuracy and efficiency, thereby reducing the pulp residue in the waste water and being beneficial to improving the subsequent purification effect. The filtered waste water enters the purification box 5 through the connecting pipe 4. Then, add the medicament into the medicine storage cylinder 8. The medicament reaches the upper opening 22 of the medicine storage shell 20 through each hose 19. At this time, the medicine receiving cavity formed by the cooperation of the soft pad 26 and the rotating shell 27 is not aligned with the upper opening 22. Therefore, the medicament will only fall on the outer wall of the rotating shell 27. Then, use the first motor 21 to drive the rotating shell 27 to rotate until the medicine receiving cavity is aligned with the upper opening 22, and then the medicament will fall into the medicine receiving cavity. Next, the rotating shell 27 continues to rotate. The medicament in the medicine receiving cavity will move along with the rotating shell 27, while the medicament not in the medicine receiving cavity still stays at the upper opening 22. Since the edge of the medicine receiving cavity is in contact with the inner wall of the medicine storage shell 20 when the rotating shell 27 rotates, the medicine receiving cavity is closed and the medicament will not flow out of the medicine receiving cavity. When the medicine receiving cavity moves to the lower opening, the medicament falls into the purification box 5. At the same time, drive the first gear 12 to rotate through the third motor 36, so that the first gear ring 13 and the medicine storage cylinder 8 rotate simultaneously, and then multiple medicine storage shells 20 move in a circular motion at the same time. Moreover, drive the third gear 38 and the first connecting rod 16 on one side to rotate through the fourth motor 37, and then the second gear ring 15 rotates on the mounting ring 14. Under the transmission of the third gear 38 and the second gear ring 15, multiple first connecting rods 16 and second connecting rods 17 rotate simultaneously to adjust the distance between the medicine storage shell 20 and the medicine storage cylinder 8, and the hose 19 is stretched. Through the above operations, the medicine storage shell 20 can move regularly above the purification box 5, and the medicament will be evenly added to each area inside the purification box 5. At this time, drive the stirring shaft 24 to rotate through the second motor 23, and use the stirring blades 25 to stir the medicament and the waste water, so that the medicament and the waste water will be mixed faster, thereby improving the purification efficiency of the waste water. Moreover, since the soft pad 26 is elastic, the soft pad 26 can be stretched by driving the push plate 31 to move through the first cylinder 30, thereby adjusting the volume of the medicine receiving cavity. At the same time, by controlling the rotation speed of the rotating shell 27, the timing and the single addition amount of the medicament can be controlled according to the amount of waste water and the purification situation inside the purification box 5, avoiding the situation that the concentration of the medicament rises rapidly when all the solid medicament enters the purification box 5 at one time, and then the concentration of the medicament will decrease due to the continuous addition of the waste water, resulting in large fluctuations in the medicament concentration, being difficult to ensure the continuous treatment effect, and being prone to waste of the medicament. When the waste water is processed in the purification box 5, the valve on the water outlet pipe 6 can be opened to discharge the processed waste water.During the medicine receiving process in the medicine receiving cavity, the motor seven 45 drives the eccentric block 32 to continuously rotate. The eccentric block 32 continuously presses the rack bar 33, causing the rack bar 33 to slide on the sliding column 46 and reset under the action of the spring 47. Then the rack bar 33 moves up and down reciprocally, causing the two-sided gear two 34 and the chute bar 35 to also rotate reciprocally. Then, through the cooperation of the chute bar 35 and the guide post 48, the connecting plate 29 slides reciprocally inside the rotating shell 27, and the blade 28 will continuously move and cut the medicine in the medicine receiving cavity and at the upper opening 22, thereby promoting the movement of the medicine and effectively avoiding the situation that the medicine gets stuck at the opening 22, affecting the amount of medicine received. Moreover, since the rotating shell 27 makes a circular motion, when the medicine receiving cavity receives the medicine and the rotating shell 27 rotates, the medicine in the medicine receiving cavity will also move. At the same time, the blade 28 continuously cuts the medicine, so that the agglomerated medicine in the medicine receiving cavity can be evenly cut, avoiding the situation that the agglomerated medicine is added to the wastewater, affecting the subsequent reaction effect of the medicine and the wastewater. Whenever the length of the hose 19 is adjusted, the motor five 40 and the motor six 43 are started. The motor five 40 drives the cylinder two 39 to rotate, and the angles of the pressing plate one 41 and the pressing plate two 42 can be adjusted to make the pressing plate one 41 and the pressing plate two 42 parallel to the hose 19. The motor six 43 drives the threaded rod 44 to rotate, and the pressing plate two 42 can slide inside the pressing plate one 41 to adjust the total length of the pressing plate one 41 and the pressing plate two 42 to be equal to the length of the hose 19. During the process of the medicine moving through the hose 19 to the medicine storage shell 20, the cylinder two 39 drives the pressing plate one 41 and the pressing plate two 42 to move, squeezing the bottom of the hose 19, and thus the movement of the medicine in the hose 19 can be promoted by pushing the bottom of the hose 19, thereby avoiding the situation that the medicine gets stuck inside the hose 19 when moving in the hose 19, further affecting the normal addition of the medicine.
