Description

Technical Field

[0001] The invention belongs to the field of wastewater treatment, in particular to a papermaking wastewater treatment device for waste paper recycling. Background Art

[0002] The waste paper recycling papermaking process usually includes processes such as crushing, deslagging, screening, purification, bleaching, and papermaking. During these processes, a large amount of wastewater containing pollutants such as pulp fiber, chemicals, suspended matter, and organic matter will be generated. This wastewater needs to be treated to remove pollutants, recover useful substances, and make the wastewater meet discharge standards.

[0003] The patent with announcement number CN215627286U discloses a wastewater treatment device for waste paper recycling and papermaking, including a filter box, the inner wall of the filter box is provided with a plurality of mounting holes, and filter slides are slidably mounted in the plurality of mounting holes, a connecting pipe is fixedly mounted on the lower end of the filter box, a purification box is fixedly mounted on the end of the connecting pipe away from the filter box, a medicine storage box is fixedly mounted on the upper end of the purification box, a fixing frame is fixedly mounted on the upper end of the medicine storage box, a servo motor is fixedly mounted on the upper end of the fixing frame, and a medicine feed block is fixedly mounted on the output end of the servo motor, which facilitates filtering out pulp from the wastewater and removing the filter slide for storing pulp without affecting the continuous filtering of pulp by the device, thereby improving the utilization rate of waste paper, and at the same time, the oxidant is continuously and extensively added to the purification box for purification through the stirring tube, and the reaction of the oxidant with wastewater is accelerated by stirring, thereby improving the wastewater treatment efficiency.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] After preliminary filtration, the wastewater will enter the purification box, and then solid medicine will be added to the medicine storage box. The solid medicine will enter the purification box through the medicine inlet pipe, and then the wastewater and solid medicine will be stirred to achieve the purpose of purifying the wastewater. However, when the solid medicine is added to the wastewater, the addition direction is relatively single, and the solid medicine will be concentrated in a local part of the inner cavity of the purification box. It will take a longer stirring time to make the wastewater and the solid medicine evenly mixed, 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 increase 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 continuous treatment effects, and easily causing waste of medicine.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The papermaking wastewater treatment equipment for waste paper recycling described in the present invention utilizes a variable-diameter auxiliary dosing assembly to enable multiple drug storage shells to move regularly above a purification tank. The drug is then evenly added to various areas within the purification tank. A stirring blade then stirs the drug and wastewater, accelerating the mixing of the two, thereby improving wastewater purification efficiency. Furthermore, the timing of drug addition and the single dose can be controlled based on the amount of wastewater within the purification tank and the purification status. This avoids the situation where all solid drugs enter the purification tank at once, causing a rapid increase in drug concentration, which then decreases due to the continued addition of wastewater. This results in large fluctuations in drug concentration, making it difficult to maintain a sustained treatment effect and easily leading to drug waste. Furthermore, compared to traditional valve-controlled dosing timing, this method ensures that each dose is consistent with the volume of the drug receiving chamber, eliminating deviations in each dose due to drug flow rate issues and enabling more precise control of the dose.

[0022] 2. The papermaking wastewater treatment equipment for waste paper recycling described in the present invention utilizes a cutting assembly that cooperates with the medicine receiving chamber. During the medicine receiving process, the blade continuously moves and cuts the medicine in the medicine receiving chamber and the upper opening, thereby promoting the movement of the medicine and effectively avoiding the situation where the medicine is stuck at the opening and affects the amount of medicine received. In addition, because the rotating shell performs a circular motion, after the medicine receiving chamber receives the medicine, the medicine in the medicine receiving chamber will also move during the rotation of the rotating shell. At the same time, the blade continuously cuts the medicine, and can evenly cut the medicine that has agglomerated in the medicine receiving chamber, thus avoiding the situation where the agglomerated medicine is added to the wastewater and affects the subsequent reaction between the medicine and the wastewater.

[0023] 3. The papermaking wastewater treatment equipment for waste paper recycling described in the present invention utilizes a feeding auxiliary component to adaptively adjust the squeezing plate 1 and the squeezing plate 2 according to the angle and length of the hose. When the agent moves through the hose to the drug storage shell, the squeezing plate 1 and the squeezing plate 2 move to squeeze the bottom of the hose, thereby promoting the movement of the agent in the hose by pushing the bottom of the hose, thereby avoiding the situation where the agent is stuck inside the hose when moving in the hose, thereby affecting the normal addition of the agent.

A soft pad 26 is fixedly connected to one side of the rotating shell 27, and the soft pad 26 and one side of the rotating shell 27 cooperate with each other to form a drug receiving cavity. Openings 22 are provided in the middle of the upper and lower sides of the drug storage shell 20, and the upper opening 22 is connected to the end of the hose 19.

[0039] In this embodiment, Figure 3-Figure 7 As shown, a stirring shaft 24 is rotatably provided at the bottom of the inner cavity of the purification box 5, and a plurality of stirring blades 25 are fixedly connected to the stirring shaft 24. A motor 23 is fixedly connected to the middle of the lower end surface of the purification box 5, and the output end of the motor 23 is fixedly connected to the lower end of the stirring shaft 24.

[0040] A gear ring 13 is sleeved and fixedly connected to the upper side of the medicine storage cartridge 8, and a gear 12 is rotatably provided on one side of the upper end surface of the mounting frame 7. The gear 12 and the tooth blocks of the outer ring of the gear ring 13 are engaged with each other. A motor 36 is fixedly connected to one side of the upper end of the mounting frame 7, and the output end of the motor 36 is fixedly connected to the gear 12.

[0041] A gear ring 2 15 is rotatably provided on the upper end surface of the mounting ring 14, and a gear 3 38 is fixedly connected to one end of the connecting rod 16. The gear 3 38 is rotatably provided on the mounting ring 14, and the gear 3 38 is engaged with the tooth block of the outer ring of the gear ring 2 15. A motor 4 37 is fixedly connected to one side of the outer wall of the drug storage cartridge 8, and the output end of the motor 4 37 is fixedly connected to the gear 3 38.

[0042] A motor 21 is fixedly connected to one side of the outer wall of the medicine storage shell 20, and the output end of the motor 21 is fixedly connected to the rotating shell 27.

[0043] One side of the inner cavity of the rotating shell 27 is fixedly connected to a cylinder 1 30 , and the piston end of the cylinder 1 30 is fixedly connected to a push plate 31 , and the push plate 31 is fixedly connected to one side of the cushion 26 .

[0044] Specifically, in the prior art, after the wastewater is initially filtered, it will enter the purification box 5, and then solid medicine will be added to the medicine storage box. The solid medicine will enter the purification box 5 through the medicine inlet pipe, and then the wastewater and the solid medicine will be stirred to achieve the purpose of purifying the wastewater. However, when the solid medicine is added to the wastewater, its addition direction is relatively single, and the solid medicine will be concentrated in a local part of the inner cavity of the purification box 5. It will take a longer stirring time to make the wastewater and the solid medicine evenly mixed, thereby affecting the wastewater purification efficiency. Moreover, when the solid medicine is added to the purification box 5, all the solid medicines will enter the purification box 5 through the medicine inlet pipe at one time, which will cause the medicine concentration to increase 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 continuous treatment effects, and easily causing waste of medicines.

[0045] Therefore, in order to solve the above problems, when this embodiment is in use, the water inlet pipe 3 is connected to the wastewater discharge pipe, and the wastewater 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 wastewater. Moreover, this graded filtration method can more accurately intercept pulp and impurities of different particle sizes, greatly improving the filtration accuracy and efficiency, thereby reducing the pulp residue in the wastewater, which is conducive to improving the subsequent purification effect.

[0046] The filtered wastewater enters the purification box 5 through the connecting pipe 4, and then the medicine is added to the medicine storage cylinder 8. The medicine reaches the upper end opening 22 of the medicine storage shell 20 through each hose 19. At this time, the medicine receiving cavity formed by the soft pad 26 and the rotating shell 27 is not aligned with the upper end opening 22, so the medicine will only fall on the outer wall of the rotating shell 27. Then, the motor 21 is used to drive the rotating shell 27 to rotate until the medicine receiving cavity is aligned with the upper end opening 22, and the medicine will fall into the medicine receiving cavity. Then the rotating shell 27 continues to rotate, and the medicine in the medicine receiving cavity will move with the rotating shell 27, while the medicine not in the medicine receiving cavity still stays at the upper end opening 22. Because 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 medicine will not flow out of the medicine receiving cavity. When the medicine receiving cavity moves to the lower end opening, the medicine falls into the clean water. In the purification box 5, at the same time, the motor 36 drives the gear 12 to rotate, so that the ring gear 13 and the drug storage cartridge 8 rotate at the same time, and the multiple drug storage shells 20 make circular motions at the same time, and the motor 4 37 drives the gear 3 38 and the connecting rod 16 on one side to rotate, so that the ring gear 2 15 rotates on the mounting ring 14. Under the transmission of the gear 3 38 and the ring gear 2 15, the multiple connecting rods 16 and 17 rotate at the same time to adjust the distance between the drug storage shell 20 and the drug storage cartridge 8, and the hose 19 is stretched. Through the above operation, the drug storage shell 20 can be regularly moved above the purification box 5, and the drug will be evenly added to various areas inside the purification box 5. At this time, the stirring shaft 24 is driven to rotate by the motor 2 23, and the stirring blade 25 is used to stir the drug and wastewater, so that the drug and wastewater are mixed faster, thereby improving the purification efficiency of the wastewater.

[0047] Furthermore, since the cushion 26 is elastic, the push plate 31 can be moved by the cylinder 30 to stretch the cushion 26, thereby adjusting the volume of the medicine receiving chamber. At the same time, the rotation speed of the rotating shell 27 can be controlled to control the timing of adding the medicine and the single addition amount according to the amount of wastewater inside the purification box 5 and the purification status. This avoids the situation where all the solid medicine enters the purification box 5 at once, causing the medicine concentration to rise rapidly, and then the medicine concentration will decrease due to the continuous addition of wastewater, resulting in large fluctuations in the medicine concentration, making it difficult to ensure a continuous treatment effect, and easily causing medicine waste.

[0048] When the wastewater is completely treated in the purification tank 5, the valve on the outlet pipe 6 can be opened to discharge the treated wastewater.

[0049] In this embodiment, Figure 7 、 Figure 8 、 Figure 10 As shown, the rotating shell 27 is also provided with a medicine receiving cavity and a cooperative cutting assembly;

[0050] The medicine receiving chamber cooperative cutting assembly includes a connecting plate 29 slidably connected to both sides of the rotating shell 27, and a blade 28 is fixedly connected to one side of the connecting plate 29. The blade 28 is located inside the medicine receiving chamber.

[0051] The gears 33 are connected to the gears 34 on one side and the gears 35 are connected to the gears 35 on the other side.

[0052] Specifically, in the above embodiment, although the medicine receiving chamber can be used to receive the medicine, since the medicine is solid, the medicine may agglomerate. This will not only cause the medicine to be stuck at the opening 22 when the medicine receiving chamber receives the medicine, affecting the amount of medicine received, but also affect the subsequent reaction effect between the medicine and the wastewater.

[0053] Therefore, in order to solve the above problems, when the present embodiment is in use, during the medicine receiving process, the motor 7 45 drives the eccentric block 32 to rotate continuously, and the eccentric block 32 continuously squeezes the rack rod 33, so that the rack rod 33 slides on the sliding column 46, and the rack rod 33 is reset under the action of the spring 47, and the rack rod 33 reciprocates up and down, so that the gear 2 34 and the slide rod 35 on both sides also rotate reciprocatingly, and the slide rod 35 can cooperate with the guide column 48 to make the connecting plate 29 slide reciprocatingly on the inner side of the rotating shell 27, so that the blade 28 will not The rotating shell 27 continuously moves and cuts the medicine in the medicine receiving chamber and the upper opening 22, thereby promoting the movement of the medicine and effectively avoiding the situation where the medicine is stuck in the opening 22 and affects the amount of medicine received. In addition, since the rotating shell 27 performs a circular motion, after the medicine receiving chamber receives the medicine, the medicine in the medicine receiving chamber will also move during the rotation of the rotating shell 27. At the same time, the blade 28 continuously cuts the medicine, which can evenly cut the agglomerated medicine in the medicine receiving chamber and avoid the situation where the agglomerated medicine is added to the wastewater and affects the subsequent reaction effect of the medicine and the wastewater.

[0054] In this embodiment, Figure 5 and Figure 9 As shown, multiple groups of auxiliary components for feeding are also provided at the bottom of the drug storage cylinder 8;

[0055] The material discharging auxiliary component includes a cylinder 2 39 rotatably arranged at the bottom of the medicine storage barrel 8, the piston end of the cylinder 2 39 is fixedly connected to an extrusion plate 1 41, and the inner side of the extrusion plate 1 41 is plugged and slidably connected to an extrusion plate 2 42.

[0056] The lower end surface of the drug storage cartridge 8 is fixedly connected to a plurality of motors five 40, the output end of the motor five 40 is fixedly connected to one side of the cylinder two 39, a threaded rod 44 is threadedly connected to one side of the extrusion plate two 42, one end of the threaded rod 44 is rotatably set on the extrusion plate one 41, and a motor six 43 is fixedly connected to one side of the extrusion plate one 41, and the output end of the motor six 43 is fixedly connected to one end of the threaded rod 44.

[0057] Specifically, in the above embodiment, although the dosing direction can be controlled by adjusting the distance between the drug storage shell 20 and the drug storage barrel 8, this will cause the angle of the hose 19 to change. Moreover, the farther the distance between the drug storage shell 20 and the drug storage barrel 8 is, the closer the hose 19 will be to horizontal. As a result, the drug is likely to get stuck inside the hose 19 when moving in the hose 19, thereby affecting the normal addition of the drug.

[0058] Therefore, in order to solve the above problems, when the present embodiment is in use, whenever the length of the hose 19 is adjusted, the motor five 40 and the motor six 43 are started, and the motor five 40 drives the cylinder two 39 to rotate, and the angle of the extrusion plate one 41 and the extrusion plate two 42 can be adjusted so that the extrusion plate one 41 and the extrusion plate two 42 are parallel to the hose 19. The motor six 43 drives the threaded rod 44 to rotate, and the extrusion plate two 42 can slide inside the extrusion plate one 41, and the total length of the extrusion plate one 41 and the extrusion plate two 42 is adjusted so that the total length is equal to the length of the hose 19. In the process of the medicine moving from the hose 19 to the medicine storage shell 20, the cylinder two 39 drives the extrusion plate one 41 and the extrusion plate two 42 to move, and squeeze the bottom of the hose 19, 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 where the medicine is stuck inside the hose 19 when moving in the hose 19, thereby affecting the normal addition of the medicine.

[0059] Working principle: The water inlet pipe 3 is connected to the wastewater discharge pipe, and the wastewater 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 wastewater. Moreover, this graded filtration method can more accurately intercept pulp and impurities of different particle sizes, greatly improving the filtration accuracy and efficiency, thereby reducing the pulp residue in the wastewater, which is conducive to improving the subsequent purification effect. The filtered wastewater enters the purification box 5 through the connecting pipe 4, and then the medicine is added to the medicine storage cylinder 8. The medicine reaches the upper end opening 22 of the medicine storage shell 20 through each hose 19. At this time, the medicine receiving cavity formed by the soft pad 26 and the rotating shell 27 is not aligned with the upper end opening 22, so the medicine will only fall on the outer wall of the rotating shell 27. Then, the rotating shell 27 is driven by the motor 21 to rotate until the medicine receiving cavity is aligned with the upper end opening 22, and the medicine will fall into the medicine receiving cavity. Then the rotating shell 27 continues to rotate, and the medicine in the medicine receiving cavity will move with the rotating shell 27, while the medicine not in the medicine receiving cavity will still stay At the upper opening 22, since the edge of the medicine receiving chamber fits with the inner wall of the medicine storage shell 20 when the rotating shell 27 rotates, the medicine receiving chamber is closed and the medicine will not flow out of the medicine receiving chamber. When the medicine receiving chamber moves to the lower opening, the medicine falls into the purification box 5. At the same time, the motor 36 drives the gear 12 to rotate, so that the ring gear 13 and the medicine storage cartridge 8 rotate at the same time, and multiple medicine storage shells 20 make circular motions at the same time. In addition, the motor 4 37 drives the gear 3 38 and the connecting rod 16 on one side to rotate, and the ring gear 2 15 rotates on the mounting ring 14. Under the transmission of the gear 3 38 and the ring gear 2 15, multiple roots The connecting rod 16 and the connecting rod 2 17 rotate at the same time to adjust the distance between the medicine storage shell 20 and the medicine storage cylinder 8. The hose 19 is stretched. The above operation can make the medicine storage shell 20 move regularly above the purification box 5, and the medicine will be evenly added to various areas inside the purification box 5. At this time, the stirring shaft 24 is driven to rotate by the motor 23, and the stirring blade 25 is used to stir the medicine and wastewater. The medicine and wastewater will be mixed faster, thereby improving the purification efficiency of the wastewater. In addition, since the soft pad 26 is elastic, the soft pad 26 can be moved by the cylinder 1 30 to drive the push plate 31 to move. 6 is stretched, thereby adjusting the volume of the medicine receiving chamber. At the same time, the rotation speed of the rotating shell 27 is controlled, and the timing of adding the medicine and the single addition amount can be controlled according to the amount of wastewater inside the purification box 5 and the purification situation, thereby avoiding the situation where all solid medicines enter the purification box 5 at one time, the medicine concentration increases rapidly, and then the medicine concentration decreases due to the continuous addition of wastewater, resulting in large fluctuations in the medicine concentration, making it difficult to ensure a continuous treatment effect, and easily causing a waste of medicine; when the wastewater is treated in the purification box 5, the valve on the water outlet pipe 6 can be opened to discharge the treated wastewater.When the medicine receiving chamber is receiving medicine, the motor 7 45 drives the eccentric block 32 to rotate continuously, and the eccentric block 32 continuously squeezes the rack rod 33, so that the rack rod 33 slides on the sliding column 46, and the rack rod 33 is reset under the action of the spring 47, and the rack rod 33 reciprocates up and down, so that the gear 2 34 and the slide rod 35 on both sides also rotate reciprocatingly, and the slide rod 35 can cooperate with the guide column 48 to make the connecting plate 29 slide reciprocatingly inside the rotating shell 27, so that the blade 28 will continuously move and cut the medicine receiving chamber and the upper The medicine at the end opening 22 is promoted, thereby promoting the movement of the medicine, effectively avoiding the situation where the medicine is stuck at the opening 22 and the amount of medicine received is affected, and since the rotating shell 27 performs a circular motion, after the medicine receiving chamber receives the medicine, the medicine in the medicine receiving chamber will also move during the rotation of the rotating shell 27. At the same time, the blade 28 continues to cut the medicine, and the agglomerated medicine in the medicine receiving chamber can be evenly cut to avoid the agglomerated medicine being added to the wastewater, which affects the subsequent reaction effect of the medicine and the wastewater. Whenever the length of the hose 19 is adjusted, the motor 5 40 and the motor 6 43 are started, and the motor 5 40 drives the cylinder 2 39 to rotate, which can adjust the angles of the extrusion plate 1 41 and the extrusion plate 2 42 so that the extrusion plate 1 41 and the extrusion plate 2 42 are parallel to the hose 19. The motor 6 43 drives the threaded rod 44 to rotate, which can make the extrusion plate 2 42 slide inside the extrusion plate 1 41, and adjust the total length of the extrusion plate 1 41 and the extrusion plate 2 42 so that the total length is equal to the length of the hose 19. In the process of the medicine moving from the hose 19 to the medicine storage shell 20, the cylinder 2 39 drives the extrusion plate 1 41 and the extrusion plate 2 42 to move, squeezing the bottom of the hose 19, thereby promoting the movement of the medicine in the hose 19 by pushing the bottom of the hose 19, thereby avoiding the situation where the medicine is stuck inside the hose 19 when moving in the hose 19, thereby affecting the normal addition of the medicine.
