Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, in particular to a papermaking wastewater sedimentation recovery device for papermaking. Background Art

[0002] The papermaking industry generates a large amount of wastewater during the paper manufacturing process. For the treatment of wastewater, the wastewater is first introduced into the primary sedimentation tank for preliminary sedimentation, and then the effluent is introduced into the coagulation sedimentation tank and flocculants are added for coagulation and sedimentation to form a mixture of precipitated residue and sewage. Finally, the precipitated residue is separated from the sewage for subsequent recycling and treatment.

[0003] When treating sewage, the existing wastewater treatment device usually uses an extraction pump to pump the sewage into the device at one time, and then filters it through the filtering structure. However, in the case of wastewater with a high slag content, the solid particles in the wastewater will have a strong mutual interference effect in the subsequent sedimentation process. On the one hand, due to the presence of surrounding coarse particles and their complex interactions, it is difficult for fine particles to obtain normal sedimentation conditions, and they are easy to suspend in the water and difficult to follow the conventional gravity sedimentation law to settle to the bottom of the sedimentation tank. On the other hand, the high slag content significantly changes the physical properties of the water body, especially greatly increases the viscosity of the water body. The increase in viscosity causes the movement of particles in the water to face greater resistance, further hinders the precipitation process of the particles, and significantly reduces the precipitation efficiency. More importantly, this continuous extraction method is very likely to cause the impurity particles in the sewage to block the filter. Due to the large number and volume of the impurity particles, when they flow into the filter with a large amount of sewage, they are very likely to accumulate and get stuck in the pores of the filter. As time goes by, the accumulated impurities are increasing, which eventually leads to the complete blockage of the pores of the filter, the filtration channel is blocked, and the subsequent sewage cannot be filtered normally through the filter, thereby causing a sharp decline in the filtration effect. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a papermaking wastewater sedimentation recovery device for papermaking, which can solve the problem that a large amount of wastewater has poor sedimentation efficiency and the filter screen is blocked by impurity particles.

[0005] To achieve the above object, the present invention provides the following technical solution: a papermaking wastewater sedimentation recovery device for papermaking, comprising a storage box and an extraction box located on the left side of the storage box, an extraction pump mounted on the top of the storage box and an intermittent structure located below the extraction box, a filter box is arranged below the extraction box, and a vibration cleaning structure is arranged above the filter box and inside the filter box; The intermittent structure includes a splash-proof frame installed at the bottom of the extraction box and connected thereto, a servo motor installed on the right side of the splash-proof frame, and a movable baffle and a water wheel rotatably connected to the inside of the splash-proof frame, the movable baffle and the water wheel rotate with the A-axis and the B-axis as axes respectively, both ends of the B-axis are fixedly connected with the A connecting rod, the bottom of the A connecting rod is rotatably connected with the B connecting rod, a scraper is provided at the bottom of the B connecting rod away from the end of the A connecting rod, the output end of the servo motor is fixedly connected with a driving gear, the outer wall of the driving gear is meshed with an intermittent gear, and the intermittent gear is fixedly connected to one end of the A-axis on a side close to the splash-proof frame.

[0006] Preferably, two slide grooves A and B are respectively provided on the inner wall of the filter box, the inner walls of the slide grooves A and B are slidably connected with movable blocks A and B respectively, and the outer walls of the movable blocks A and B are fixedly connected with filter plates.

[0007] Preferably, the vibration cleaning structure includes a return spring fixedly installed on the inner bottom wall of the A slide groove, an A movable plate fixedly connected to the top of the A movable block, and a limit frame located outside the A movable plate and slidably connected thereto, the top of the A movable plate is rotatably connected to the B movable plate, the top of the B movable plate is rotatably connected to the C movable plate, the top of the C movable plate is rotatably connected to the A pulley, and the outer sleeve of the A pulley is provided with a belt that fits tightly to the outer wall.

[0008] Preferably, a B pulley is rotatably connected to the inner wall of the belt, a transmission column is fixedly installed on one end of the B pulley away from the storage box, and the other end of the transmission column is fixedly connected to the end of the driving gear away from the servo motor.

[0009] Preferably, it also includes an impurity collection box installed on the left side of the filter box, a connected sewage trough is opened between the filter box and the impurity collection box, a hydraulic rod is installed on the inner top wall of the impurity collection box, and a baffle is installed on the bottom of the hydraulic rod, and the baffle is used to block the sewage trough to reduce the flow of sewage into the impurity collection box.

[0010] Preferably, the input end and output end of the extraction pump are respectively connected to an extraction pipe and a discharge pipe, and the other ends of the extraction pipe and the discharge pipe extend to the interior of the storage box and the extraction box respectively. When the extraction pump is started, the wastewater inside the storage box can be extracted into the extraction box through the extraction pipe.

[0011] Preferably, when the servo motor rotates, it can drive the driving gear to rotate, and the driving gear can drive the intermittent gear to rotate. At this time, the intermittent gear drives the A-axis rod and the movable baffle to flip, so that the wastewater inside the extraction box falls under the action of gravity and drives the water wheel to rotate through the impact force generated when falling.

[0012] Preferably, when the water wheel rotates, it can drive the A connecting rod to make a circular motion. At this time, the A connecting rod can drive the B connecting rod and the scraper to make an arc motion. The scraper follows the B connecting rod to make an arc motion and can push the impurities above the filter plate to one end of the filter plate close to the sewage trough.

[0013] Preferably, the filter plate is obliquely distributed at an angle of twenty-five degrees and one end of the filter plate away from the return spring is located below the drain trough, and the top of the return spring is fixedly connected to the bottom of the A movable block.

[0014] Compared with the prior art, the present invention has the following beneficial effects: Under the synergistic effect of the extraction box, the filter box and the intermittent structure, when the servo motor is started, the active gear is driven to rotate, and the active gear is tightly meshed with the intermittent gear, prompting the intermittent gear to start rotating. As the intermittent gear rotates, the A-axis rod connected thereto rotates synchronously, thereby driving the movable baffle to flip. During this process, the papermaking wastewater originally retained in the extraction box falls into the splash-proof frame, and as the intermittent gear continues to rotate, the movable baffle is reset after rotating 360 degrees. This intermittent feeding method can greatly reduce the slag content of the wastewater entering the sedimentation box by intermittently feeding the wastewater into the filter box before sedimentation. When the slag content is reduced, the mutual interference between solid particles in the wastewater is significantly reduced during the sedimentation process, thereby accelerating the sedimentation efficiency. This not only shortens the time period of wastewater treatment, but also greatly improves the stability and reliability of the entire treatment process.

[0015] In the process of the wastewater passing through the anti-splash frame from the extraction box and finally falling into the filter box, the impact force generated by the gravity acceleration when the wastewater falls will drive the water wheel to rotate. During the rotation of the water wheel, the wastewater continuously impacts the filter plate for filtration. At the same time, the rotation of the water wheel drives the B-axis rod to rotate, and the rotation of the B-axis rod further drives the two A-connecting rods to rotate. At this time, the A-connecting rod plays a transmission role, driving the B-connecting rod to perform arc-shaped reciprocating motion. During this movement, the scraper pushes the impurities on the top of the filter plate to one end of the filter plate close to the sewage trough, thereby realizing automatic cleaning of impurities generated during the filtration process and avoiding the accumulation of impurities on the filter plate, thereby ensuring the filtration efficiency and service life of the filter plate. At the same time, by utilizing the impact force of the falling wastewater to drive the water wheel and the subsequent cleaning mechanism, the energy consumption and operating cost of the entire wastewater treatment system are reduced.

[0016] The present invention adopts the design of the vibration structure. When the driving gear rotates, the B pulley is driven to rotate through the transmission column. During the rotation process, the B pulley can drive the belt to run, thereby causing the A pulley to rotate. At this time, the A pulley drives the C movable plate to rotate. The rotation of the C movable plate further causes the B movable plate to rotate, and the B movable plate can drive the A movable plate to reciprocate up and down inside the limit frame. In this process, the A movable plate can drive the A movable block to move up and down, thereby causing the filter plate to move up and down. In this up and down movement process, the reset spring plays an important synergistic role, thereby simulating the effect of vibration. This vibration makes it easier for impurities on the surface of the filter screen to move to the oblique part of the filter plate under the action of the vibration force. With the use of the scraper, the cleaning effect of the filter screen is further increased. During the movement process, the scraper can effectively push the impurities on the top of the filter plate to one end of the filter plate close to the sewage trough, and the oblique setting of the filter plate ensures that the impurity particles can slide smoothly to the sewage trough under the action of gravity, thereby greatly reducing the problem of poor filtering effect caused by clogging of the filter plate.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 14 As shown, the present invention provides a papermaking wastewater sedimentation recovery device for papermaking, comprising a storage box 1 and an extraction box 2 located on the left side of the storage box 1, an extraction pump 3 assembled on the top of the storage box 1 and an intermittent structure 4 located below the extraction box 2, a filter box 5 is arranged below the extraction box 2, and a vibration cleaning structure 6 is arranged above the filter box 5 and inside the filter box 5; The intermittent structure 4 includes a splash-proof frame 41 assembled at the bottom of the extraction box 2 and connected thereto, a servo motor 42 assembled on the right side of the splash-proof frame 41, and a movable baffle 43 and a water wheel 44 rotatably connected to the inside of the splash-proof frame 41. The movable baffle 43 and the water wheel 44 rotate around the A-axis 45 and the B-axis 46 respectively. Both ends of the B-axis 46 are fixedly connected to the A-connecting rod 47. The bottom of the A-connecting rod 47 is rotatably connected to the B-connecting rod 48. A scraper 49 is provided at the bottom of the B-connecting rod 48 away from one end of the A-connecting rod 47. The output end of the servo motor 42 is fixedly connected to a driving gear 421. An intermittent gear 422 is meshedly connected to the outer wall of the driving gear 421. The intermittent gear 422 is fixedly connected to one end of the A-axis 45 on one side close to the splash-proof frame 41.

[0021] The above scheme is adopted: under the synergistic effect of the extraction box 2, the filter box 5 and the intermittent structure 4, significant advantages are brought to the treatment of papermaking wastewater. When the servo motor 42 is started, the driving gear 421 is driven to rotate rapidly. Because the driving gear 421 is tightly meshed with the intermittent gear 422, under this tight connection, the intermittent gear 422 begins to rotate stably. As the intermittent gear 422 rotates, the A-axis rod 45 connected thereto also rotates synchronously. The A-axis rod 45 converts the rotational motion of the intermittent gear 422 into a flipping motion of the movable baffle 43. In this process, the papermaking wastewater originally retained in the extraction box 2 falls into the splash-proof frame 41, and the setting of the splash-proof frame 41 can effectively prevent the wastewater from splashing during the falling process, ensuring that the wastewater can accurately flow into the filter box 5 for The next step is processing, and with the continuous rotation of the intermittent gear 422, the movable baffle 43 is accurately reset after rotating 360 degrees. By intermittently feeding the wastewater into the filter box 5 before sedimentation, each intermittent feeding can allow a certain amount of wastewater to be fully filtered through the filter box 5, which greatly reduces the slag content of the wastewater entering the filter box 5. When the slag content is reduced, the wastewater undergoes significant changes in the sedimentation process, and the mutual interference between the solid particles is significantly reduced. Each particle can be more freely precipitated according to the law of gravity sedimentation, which not only speeds up the sedimentation efficiency, so that the wastewater can achieve a better sedimentation effect in a shorter time, but also greatly improves the stability and reliability of the entire treatment process, shortens the time cycle of wastewater treatment, and is crucial to improving production efficiency.

[0022] like Figures 1 to 14 As shown, two A slide grooves 51 and B slide grooves 52 are respectively opened on the inner wall of the filter box 5, and the inner walls of the A slide groove 51 and the B slide groove 52 are respectively slidably connected with the A movable block 53 and the B movable block 54, and the outer walls of the A movable block 53 and the B movable block 54 are fixedly connected with the filter plate 55, and the vibration cleaning structure 6 includes a reset spring 61 fixedly installed on the inner bottom wall of the A slide groove 51 and an A movable plate 62 fixedly connected to the top of the A movable block 53, and a limit frame 63 located outside the A movable plate 62 and slidably connected thereto, the top of the A movable plate 62 is rotatably connected to the B movable plate 64, the top of the B movable plate 64 is rotatably connected to the C movable plate 641, and the top of the C movable plate 641 is rotatably connected to the A pulley 65, and the outer part of the A pulley 65 is provided with a belt 66 that fits tightly with the outer wall.

[0023] The above scheme is adopted: when the wastewater falls, the impact force generated by the acceleration of gravity can drive the water wheel 44 to rotate. During the rotation of the water wheel 44, the wastewater continuously impacts the filter plate 55 for filtration. The filter plate 55, as a key filtering component, can effectively intercept the impurity particles in the wastewater. At the same time, the rotation of the water wheel 44 drives the B shaft rod 46 to rotate, and the rotation of the B shaft rod 46 further drives the two A connecting rods 47 to rotate. At this time, the A connecting rod 47 fully plays the transmission role to transmit power to the B connecting rod 48, so that it performs arc-shaped reciprocating motion. During this movement, the scraper 49 plays a key role. The scraper 49 pushes the impurities on the top of the filter plate 55 to the end of the filter plate 55 close to the sewage tank 71 as the B connecting rod 48 moves. This automatic cleaning function is of great significance. It avoids the accumulation of impurities on the filter plate 55, ensures that the filter plate 55 always maintains good filtering performance, realizes the automatic cleaning of impurities generated during the filtration process, and ensures the filtering efficiency and service life of the filter plate 55.

[0024] like Figures 1 to 14 As shown, the inner wall of the belt 66 is also rotatably connected to a B pulley 67, and a transmission column 68 is fixedly installed at one end of the B pulley 67 away from the storage box 1, and the other end of the transmission column 68 is fixedly connected to the end of the driving gear 421 away from the servo motor 42. It also includes an impurity collection box 7 assembled on the left side of the filter box 5, and a connected sewage trough 71 is opened between the filter box 5 and the impurity collection box 7. A hydraulic rod 72 is installed on the inner top wall of the impurity collection box 7, and a baffle plate 73 is installed at the bottom of the hydraulic rod 72. The baffle plate 73 is used to block the sewage trough 71 to reduce the flow of sewage into the impurity collection box 7.

[0025] The above scheme is adopted: when the driving gear 421 rotates, its power drives the B pulley 67 to rotate through the transmission column 68. During the rotation process of the B pulley 67, it can drive the belt 66 to operate. The belt 66 is like a power transmission belt, which transmits the rotational power of the B pulley 67 to the A pulley 65, thereby causing the A pulley 65 to rotate. At this time, the A pulley 65 acts as a new power source to drive the C movable plate 641 to rotate. The rotation of the C movable plate 641 further causes the B movable plate 64 to rotate, and the B movable plate 64 can drive the A movable plate 62 to reciprocate up and down inside the limit frame 63. In this process, the A movable plate 62 can drive the A movable block 53 to move up and down, thereby causing the filter plate 55 to move up and down. In the process of the filter plate 55 moving up and down, the return spring 61 plays an important synergistic role. The elastic characteristics of the return spring 61 make the filter plate 55 have a certain elastic buffer when it moves up and down, which can simulate a more natural vibration effect. This vibration makes it easier for impurities on the surface of the filter screen to move to the filter plate 5 under the action of the vibration force. 5, the impurities overcome their own viscosity and friction under the impetus of the vibration force, and move more smoothly in a specific direction. With the use of the scraper 49, the cleaning effect of the filter screen is further increased. During the movement, the scraper 49 always maintains an efficient working state, and can effectively push the impurities on the top of the filter plate 55 to the end of the filter plate 55 close to the sewage trough 71, and the oblique setting of the filter plate 55 is one of the key factors in this cleaning process. The oblique filter plate 55 ensures that the impurity particles can slide smoothly to the sewage trough 71 under the action of gravity, realizing the automatic cleaning and centralized discharge of impurities, greatly reducing the problem of poor filtering effect caused by clogging of the filter plate 55. Clogging of the filter plate 55 is a common problem in the wastewater treatment process. Once the filter plate 55 is clogged, it will not only reduce the filtering efficiency, but also increase the equipment maintenance cost and processing time. The synergistic effect of the vibration structure, the scraper 49 and the oblique filter plate 55 effectively solves this problem, so that the wastewater treatment system can operate continuously and stably, and the stability and reliability of the filtering effect are guaranteed.

[0026] like Figures 1 to 14 As shown, the input end and the output end of the extraction pump 3 are respectively connected to the extraction pipe 31 and the discharge pipe 32, and the other ends of the extraction pipe 31 and the discharge pipe 32 extend to the inside of the storage box 1 and the extraction box 2 respectively. When the extraction pump 3 is started, the wastewater inside the storage box 1 can be extracted into the extraction box 2 through the extraction pipe 31. When the servo motor 42 rotates, it can drive the driving gear 421 to rotate, and the driving gear 421 can drive the intermittent gear 422 to rotate. At this time, the intermittent gear 422 drives the A-axis rod 45 and the movable baffle 43 to flip, so that the wastewater inside the extraction box 2 falls under the action of gravity and drives the water wheel 44 to rotate through the impact force generated when falling.

[0027] The above scheme is adopted: after the wastewater is filtered through the filter plate 55, it will enter the filter box 5 for sedimentation. A hinged closed door is provided on the outside of the filter box 5 and the impurity collection box 7. When it is necessary to clean the filter box 5 and the impurity collection box 7, the filter box 5 can be cleaned of impurities and residual wastewater settled therein to ensure the cleanliness of the inside of the filter box 5 so as to better perform the filtering and sedimentation work next time. For the impurity collection box 7, after opening the closed door, the collected impurities can be centrally processed to avoid excessive accumulation of impurities affecting the normal operation of the entire wastewater treatment system. The baffle plate 73 It plays an important blocking role in the wastewater treatment process. It is used to block the wastewater from entering the impurity collection box 7 through the drain chute 71. When the movable baffle 43 rotates 360 degrees to reset, the hydraulic rod 72 is started to drive the baffle 73 to move upward. When the baffle 73 moves upward, the impurity channel that was originally blocked is opened, so that the impurities can smoothly enter the impurity collection box 7 through the drain chute 71 for collection. This design realizes the automatic collection of impurities and improves the cleaning efficiency. At the same time, the use of the hydraulic rod 72 makes the movement of the baffle 73 more stable and reliable, and can accurately control the timing of impurity collection.

[0028] like Figures 1 to 14 As shown, when the water wheel 44 rotates, it can drive the A connecting rod 47 to make a circular motion. At this time, the A connecting rod 47 can drive the B connecting rod 48 and the scraper 49 to make an arc motion. The scraper 49 follows the B connecting rod 48 to make an arc motion and can push the impurities above the filter plate 55 to the end of the filter plate 55 close to the drain trough 71. The filter plate 55 is obliquely distributed at an angle of 25 degrees and the end of the filter plate 55 away from the reset spring 61 is located below the drain trough 71. The top of the reset spring 61 is fixedly connected to the bottom of the A movable block 53.

[0029] The above scheme is adopted: the storage tank 1 is used as the initial storage place for wastewater, carrying a large amount of wastewater to be treated. When wastewater treatment is required, the wastewater is pumped from the storage tank 1 to the extraction tank 2 through the extraction pump 3. The extraction pump 3 transports the wastewater to the extraction tank 2 with a strong power to ensure that the wastewater can smoothly enter the next treatment link. Subsequently, the passage of the wastewater from the extraction tank 2 to the filter tank 5 is opened through the rotation of the movable baffle 43, and the wastewater will fall into the filter tank 5 through the splash-proof frame 41. The design of the splash-proof frame 41 can not only prevent the wastewater from splashing during the falling process, avoiding pollution of the surrounding environment and damage to the equipment, but also guide the wastewater to the filter tank 5. Water accurately flows into the filter box 5, ensuring that the wastewater can be processed according to the predetermined process, and the movable baffle 43 will reset after rotating 360 degrees after completing a discharge. This reset action is crucial. It prevents the wastewater from continuing to fall into the filter box 5, thereby achieving the effect of intermittent discharge. Intermittent discharge has many advantages. On the one hand, it can avoid a large amount of wastewater from pouring into the filter box 5 at one time, preventing the filter box 5 from being affected by excessive load and affecting the filtering effect. On the other hand, intermittent discharge allows the wastewater to have enough time in the filter box 5 for filtering and sedimentation and other treatment processes, thereby improving the quality and efficiency of the treatment.

[0030] Working principle of the present invention: First, papermaking wastewater is stored in the storage box 1. When the extraction pump 3 is started, the extraction pump 3 extracts the wastewater inside the storage box 1 into the extraction box 2 through the extraction pipe 31 to prepare for subsequent treatment. Then the servo motor 42 is started to drive the driving gear 421 to rotate. The driving gear 421 is tightly meshed with the intermittent gear 422, so that the intermittent gear 422 starts to rotate. The intermittent gear 422 drives the A-axis rod 45 to rotate, thereby turning the movable baffle 43. At this time, the papermaking wastewater in the extraction box 2 falls into the splash-proof frame 41. The splash-proof frame 41 effectively prevents the wastewater from splashing out, ensuring that the wastewater accurately flows into the filter box 5. The baffle plate 43 is reset after rotating 360 degrees, preventing the wastewater from continuing to fall, and realizing intermittent feeding. This intermittent feeding method allows a certain amount of wastewater to be fully filtered through the filter box 5 before sedimentation, thereby reducing the amount of slag in the wastewater entering the filter box 5. During the falling process of the wastewater, the impact force generated by the acceleration of gravity drives the water wheel 44 to rotate. When the water wheel 44 rotates, the wastewater continuously impacts the filter plate 55 for filtration. The filter plate 55 intercepts the impurity particles in the wastewater, allowing relatively clear water to pass through. At the same time, the water wheel 44 drives the B shaft 46 to rotate, and the B shaft 46 drives the A connecting rod 47 to rotate. The A connecting rod 47 plays a transmission role, driving the B The connecting rod 48 makes an arc-shaped reciprocating motion. During this process, the scraper 49 pushes the impurities on the top of the filter plate 55 to one end of the filter plate 55 close to the sewage tank 71, so as to automatically clean the impurities. When the driving gear 421 rotates, its power drives the B pulley 67 to rotate through the transmission column 68, and the B pulley 67 drives the belt 66 to operate, thereby rotating the A pulley 65, and the A pulley 65 drives the C movable plate 641 to rotate, so that the B movable plate 64 rotates, and then drives the A movable plate 62 to reciprocate up and down in the limit frame 63, and the A movable plate 62 drives the A movable block 53 to move up and down, so that the filter plate 55 also moves up and down, and the filter plate 55 moves up and down accordingly. The positioning spring 61 plays a synergistic role in this process, simulating the vibration effect. This vibration makes it easier for impurities on the surface of the filter plate 55 to move to the oblique part of the filter plate 55, and cooperates with the scraper 49 to further increase the cleaning effect. The obliquely arranged filter plate 55 ensures that the impurities slide smoothly to the drain chute 71 under the action of gravity. The wastewater enters the filter box 5 for sedimentation after being filtered by the filter plate 55. When it is necessary to clean the filter box 5 and the impurity collection box 7, the hinged closed door can be opened to centrally process the collected impurities. After stopping the discharge of water, the hydraulic rod 72 is started to drive the baffle plate 73 to move upward, and the impurities enter the impurity collection box 7 through the drain chute 71 for collection.
