Description

Technical Field

[0001] The invention relates to the technical field of papermaking wastewater treatment, in particular to a papermaking wastewater sedimentation recovery device and a recovery method thereof. Background Art

[0002] Papermaking wastewater mainly comes from the two process stages of pulping and papermaking. Wastewater treatment is a crucial environmental protection link in the papermaking industry. Since the papermaking process consumes a large amount of water resources and produces wastewater containing high concentrations of organic matter, suspended solids and chemical agents, effective measures must be taken to treat the wastewater to reduce pollution to the environment and achieve rational use of resources.

[0003] Current wastewater treatment devices generally use filters to quickly filter out precipitated residues in the water. However, after long-term use, impurities and pollutants are easily accumulated on the surface of the filter, resulting in a decrease in filtration efficiency and affecting the effect of wastewater treatment, making the treated water quality unable to meet discharge or reuse standards. If the filter is cleaned and maintained manually, it will not only significantly increase the workload and cost of maintenance personnel, but may also interrupt the continuity of the production process and pose certain safety risks.

[0010] Preferably, the output end of the cylinder is fixedly connected to a discharge port, and the outer wall of the discharge port is fixedly inserted into the interior of the shell, a hot air blower is fixedly installed on one side of the outer wall of the shell, and the input end of the hot air blower is fixedly connected to an air inlet.

[0013] Preferably, the outer wall of the filter tank is fixedly mounted to the outer wall of the housing, and the input end of the filter tank is fixedly connected to the output end of the drain pipe.

[0014] A recycling method for a papermaking wastewater sedimentation recovery device comprises the following steps: Step 1: Wastewater is injected into the filter tank through the water inlet. The filter screen 1 efficiently removes solid particles in the wastewater. Waste residues accumulate on the surface of the filter screen, and the wastewater after preliminary filtration quickly flows out through the drain port, which can significantly shorten the wastewater treatment time; Step 2: Start the motor 1 to drive the rotating shaft to rotate, driving the scraper, the fixed rod and the cleaning roller to perform circular motion. At the same time, the gear 1 and the gear 2 interact with each other to achieve reverse rotation. The threaded sleeve 1 and the threaded sleeve 2 cooperate to push the threaded rod up, thereby pushing the filter 1 up. When the filter 1 contacts the scraper and the cleaning roller, the electromagnet attracts the iron core to move the connecting column while the filter 1 remains stationary. The cleaning roller uses bristles or cleaning materials to remove pollutants on the surface of the filter 1, and the scraper scrapes off strong attachments to ensure thorough cleaning. Step 3: The pollutants removed during the cleaning process are sent to the inside of the shell and naturally fall to the top of the second filter. The second filter allows the water in the impurities to penetrate and flow to the bottom of the shell. The drain valve automatically starts to return the excess sewage to the treatment area through the drain pipe, effectively reducing the water content of the pollutants and laying the foundation for the subsequent drying steps; Step 4: After the hot air blower draws in heated air through the air inlet, it delivers the hot air to the inside of the shell through the air inlet pipe. At the same time, motor 2 starts, driving the spiral blades to rotate inside the cylinder, driving the pollutants to spiral up. The air holes on the outer wall of the cylinder allow the hot air to come into contact with the moist pollutants, achieving efficient drying. Finally, the dried pollutants are discharged smoothly through the discharge port, significantly reducing the weight and volume of the waste residue and reducing disposal costs. At the same time, it prevents the moist waste residue from corroding the equipment and breeding bacteria, thereby extending the service life of the equipment.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when the filter screen needs to be cleaned, it is only necessary to start the motor, and the motor drives the rotating shaft to rotate, thereby driving the scraper, the fixing rod and the cleaning roller to perform circular motion, thereby effectively removing pollutants on the surface of the filter screen. The device can regularly clean the filter screen to prevent the filter screen from being blocked, thereby ensuring that wastewater can pass through the filter screen smoothly, thereby improving the efficiency and effect of wastewater treatment. Automated cleaning also reduces the complexity and cost of manual maintenance, and the entire device only needs one power source to realize the lifting, cleaning and slag discharge of the filter screen, thereby simplifying the equipment structure, reducing the equipment failure rate, and achieving energy saving and consumption reduction, thereby reducing the cost of wastewater treatment.

[0016] In the present invention, the hot air blower inhales external air, heats it, and then transports it to the inside of the shell, where it comes into contact with the moist pollutants to achieve efficient drying, which significantly reduces the weight and volume of the waste residue. This not only reduces the disposal cost of the waste residue, but also avoids the corrosion of the equipment by the moist waste residue and the growth of bacteria, thereby greatly extending the service life of the equipment.

[0017] In the present invention, wastewater is injected into the filter tank through the water inlet, and the filter screen can quickly remove solid particles in the wastewater, such as wood chips, bark and other impurities, which significantly shortens the time for wastewater treatment. The filter screen can continuously and stably remove suspended matter in the wastewater, thereby ensuring the stability of the effluent water quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Example 1: Reference Figure 1 - Figure 8 As shown, the present invention provides a papermaking wastewater sedimentation recovery device, comprising a cleaning mechanism 1, and a drying mechanism 2 is fixedly installed on the outer wall of the cleaning mechanism 1; The cleaning mechanism 1 includes a filter tank 101, a motor 102 is fixedly installed on the top of the filter tank 101, a rotating shaft 103 is fixedly installed on the output end of the motor 102, and the outer wall of the rotating shaft 103 is movably inserted into the interior of the filter tank 101, a scraper 104 is fixedly installed on the outer wall of the rotating shaft 103, a fixed rod 105 is fixedly installed on the outer wall of the rotating shaft 103, and a cleaning roller 106 is movably sleeved on the outer wall of the fixed rod 105, a gear 110 is fixedly sleeved on the outer wall of the rotating shaft 103, a bracket 111 is movably sleeved on the outer wall of the rotating shaft 103, and the outer wall of the bracket 111 is fixedly inserted into the interior of the filter tank 101, the outer wall of the gear 110 is meshedly connected with four gears 2 112, the inner walls of the four gears 2 112 are all fixedly inserted with threaded sleeves 113, the inner walls of the four threaded sleeves 113 are all threadedly connected with threaded sleeves 2 114, and the four threaded sleeves 2 114 are The inner surface wall of the four connecting columns 116 is threadedly connected with a threaded rod 115, and the tops of the four threaded rods 115 are fixedly installed with a connecting column 116. The tops of the four connecting columns 116 are provided with a mounting hole 117, and the inner surface walls of the four mounting holes 117 are fixedly inserted with an electromagnet 118. The outer surface wall of the four connecting columns 116 is provided with a group of mounting grooves 119, and a spring 120 is fixedly installed on one side of the inner wall of the four groups of mounting grooves 119. An iron core 121 is fixedly installed on one side of the outer wall of the four groups of springs 120, and the inner surface walls of the four groups of mounting grooves 119 are movably inserted with the outer surface wall of the iron core 121, and a connecting sleeve 122 is movably sleeved between the outer walls of the four groups of iron cores 121, and the outer walls of the four connecting columns 116 are movably inserted inside the connecting sleeve 122, and a filter screen 123 is fixedly installed between the tops of the four connecting sleeves 122, and the outer wall of the filter tank 101 is fixedly installed with the outer wall of the outer shell 201.

[0022] In this embodiment, when it is necessary to clean the filter screen 123, people can start the motor 102. At this time, the motor 102 can drive the shaft 103 to rotate inside the filter tank 101, and the scraper 104, the fixed rod 105 and the cleaning roller 106 located on the outer wall of the shaft 103 start to make circular motion. At the same time, the gear 110 fixedly sleeved on the outer wall of the shaft 103 starts to rotate, and drives the multiple gears 112 meshing with it to start rotating in the opposite direction. The threaded sleeve 113 inside the gear 112 is driven to rotate inside the bracket 111. At this time, the threaded sleeve 114 inside the threaded sleeve 113 is continuously extended from the inside of the threaded sleeve 113 under the action of the thread. When the threaded sleeve 114 is fully extended, it will rotate together with the threaded sleeve 113, thereby driving the threaded rod 115 with the help of the internal thread. When the filter screen 123 contacts the moving scraper 104 and the cleaning roller 106, the electromagnet 118 starts to be energized to generate magnetic force, driving the iron core 121 inside the connecting column 116 to move toward the inside of the mounting groove 119. When the iron core 121 is completely pulled out from the inside of the connecting sleeve 122, the rotating threaded rod 115 will only drive the top connecting column 116 to move, and the connecting sleeve 122 and the filter screen 123 movably sleeved on the outer wall of the connecting column 116 will be in a stationary state. When the cleaning roller 106 makes a circular motion, it will also rotate on the outer wall of the fixed rod 105, thereby removing the pollutants accumulated on the surface of the filter screen 123. The scraper 104 can further scrape off the strongly attached pollutants and send the pollutants to the inside of the shell 201 for treatment.

[0023] Embodiment 2: According to Figure 1 , Figure 2 , Figure 3 , Figure 7 as well as Figure 8As shown, the drying mechanism 2 includes a shell 201, a shaft hole 202 is opened at the top of the shell 201, a motor 203 is fixedly installed on the top of the shell 201, a spiral blade 204 is fixedly installed at the output end of the motor 203, and the outer wall of the spiral blade 204 is movably inserted into the inside of the shaft hole 202, a filter 205 is fixedly inserted on the inner wall of the shell 201, a cylinder 206 is fixedly installed on the top of the inner wall of the shell 201, and the output end of the cylinder 206 is fixedly connected to a discharge port 207, and the outer wall of the discharge port 207 is fixedly connected to the outer wall of the discharge port 207. The hot air blower 208 is fixedly installed on one side of the outer wall of the shell 201, and the input end of the hot air blower 208 is fixedly connected to the air inlet 209, and the output end of the hot air blower 208 is fixedly connected to two air inlet pipes 210, and the output ends of the two air inlet pipes 210 are fixedly connected to the input end of the shell 201, and the bottom of the shell 201 is fixedly connected to a drain valve 211, and the output end of the drain valve 211 is fixedly connected to a drain pipe 212, and the input end of the filter tank 101 is fixedly connected to the output end of the drain pipe 212.

[0024] In this embodiment, after the pollutants are sent to the inside of the shell 201, they will fall to the top of the second filter screen 205 under the action of gravity, and the moisture in the impurities will pass through the second filter screen 205 and flow to the bottom of the shell 201. At this time, the drain valve 211 is activated, and the sewage can flow back to the inside of the drain pipe 212 through the drain pipe 212, which effectively reduces the water content in the pollutants and provides convenience for the subsequent drying process. Then the hot air blower 208 starts to start, and the outside air is sucked into the hot air blower 208 through the air inlet 209, and the heated air is transported to the inside of the air inlet pipe 210. The hot air is brought to the inside of the shell 201 by the air inlet pipe 210. At this time, the motor 20 3 are started synchronously, driving the spiral blade 204 to rotate inside the cylinder 206. At this time, the pollutants located at the bottom of the cylinder 206 will be driven by the spiral blade 204 and spirally rise inside the cylinder 206. Since the outer wall of the cylinder 206 is provided with a plurality of air holes, the hot air inside the shell 201 can contact the moist pollutants through the air holes, thereby drying the pollutants. The dried pollutants can be discharged through the discharge port 207, which can significantly reduce the weight and volume of the waste residue, thereby reducing the disposal cost of the waste residue, and can also effectively prevent the moist waste residue from corroding the equipment and breeding bacteria, thereby extending the service life of the equipment and reducing the pollution of the waste residue to the environment.

[0025] Embodiment 3: According to Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 6 As shown, the cleaning mechanism 1 includes a filter tank 101, the top of the filter tank 101 is fixedly connected to a water inlet 107, the bottom of the filter tank 101 is fixedly connected to a drain outlet 108, and a filter screen 123 is fixedly installed between the tops of four connecting sleeves 122.

[0026] In this embodiment, when wastewater treatment is required, people can inject wastewater into the filter tank 101 through the water inlet 107. At this time, the filter screen 123 can effectively remove solid particles in the wastewater, so that waste residues accumulate on its surface, and the filtered wastewater can quickly flow out through the drain port 108. The filter screen 123 quickly removes suspended matter in the wastewater, such as wood chips, bark, plastic fragments and pulp fibers, so that people do not need to wait for the suspended matter to settle naturally as in the sedimentation method, thereby significantly reducing the time for wastewater treatment.

[0027] The working principle of the whole mechanism is as follows: in the wastewater treatment process, firstly, the wastewater is injected into the inner space of the filter tank 101 through the special water inlet 107, and the filter screen 123 can effectively remove the solid particles in the wastewater. These waste residues will accumulate on the surface of the filter screen 123, and the wastewater after preliminary filtration can quickly flow out through the drain port 108, thereby greatly shortening the wastewater treatment time. When it is necessary to clean and maintain the filter screen 123, the operation becomes simple and efficient. Just start the motor 102, it will drive the shaft 103 to start rotating in the filter tank 101. As the shaft 103 rotates, the scraper 104, the fixing rod 105 and the cleaning roller 106 installed on its outer wall also perform circular motion. At the same time, the gear 110 fixedly mounted on the outer wall of the rotating shaft 103 also starts to rotate, and realizes reverse rotation through the interaction with multiple gears 112 meshing with it. The gears 112 are equipped with threaded sleeves 113 inside. When they rotate inside the bracket 111, the internal threaded sleeves 114 gradually extend out of the threaded sleeves 113 under the action of the threads. When the threaded sleeves 114 are fully extended, they will rotate together with the threaded sleeves 113, and then push the threaded rod 115 to extend upward through the internal threads. In this process, the upward movement of the threaded rod 115 continuously pushes the filter screen 123 on the top. When the filter screen 123 contacts the moving scraper 104 and the cleaning roller 106, The electromagnet 118 is energized to generate magnetic force, which attracts the iron core 121 inside the connecting column 116 to move into the installation groove 119. When the iron core 121 is completely pulled out of the connecting sleeve 122, the rotating threaded rod 115 will only drive the top connecting column 116 to move, while the connecting sleeve 122 and the filter screen 123 that are movably sleeved on the outer wall of the connecting column 116 will remain stationary. At this time, the cleaning roller 106 will rotate freely on the outer wall of the fixed rod 105 while making a circular motion, and use the bristles or cleaning materials on its surface to effectively remove the pollutants accumulated on the surface of the filter screen 123. The scraper 104 is responsible for further scraping off those strongly attached pollutants to ensure the thoroughness of the cleaning. These removed pollutants are then sent to the outer shell 201. The impurities are further processed inside, and they will naturally fall to the top of the second filter screen 205 under the action of gravity. The design of the second filter screen 205 allows the moisture in the impurities to penetrate and flow to the bottom of the shell 201. At this time, the drain valve 211 will automatically start to return the excess sewage to the corresponding treatment area through the drain pipe 212. This process effectively reduces the water content in the pollutants and lays a good foundation for the subsequent drying steps. Then, the hot air blower 208 starts to operate. It inhales the outside air through the air inlet 209, and after heating it inside, it transports the hot air to the inside of the shell 201 through the air inlet pipe 210. At the same time, the motor 203 starts synchronously to drive the spiral blade 204 to rotate inside the cylinder 206.The waste residue at the bottom of the cylinder 206 is driven by the spiral blades 204 and spirally rises along the inner wall of the cylinder 206. A plurality of air holes are cleverly opened on the outer wall of the cylinder 206, so that the hot air inside the shell 201 can smoothly pass through these air holes to contact the moist pollutants, thereby achieving an efficient drying effect. Finally, the pollutants that have been dried are smoothly discharged through the discharge port 207. This step not only significantly reduces the weight and volume of the waste residue, thereby reducing the disposal cost of the waste residue, but more importantly, it effectively avoids the corrosion of the equipment by the moist waste residue and the breeding of bacteria, greatly extending the service life of the equipment.

[0028] The present invention also provides a recovery method of a papermaking wastewater sedimentation recovery device, comprising the following steps: Step 1: wastewater is injected into the filter tank 101 through the water inlet 107, and the filter screen 123 efficiently removes solid particles in the wastewater, and waste residues accumulate on the surface of the filter screen, and the wastewater after preliminary filtration quickly flows out through the drain port 108, which can significantly shorten the wastewater treatment time; Step 2: Start the motor 102 to drive the rotating shaft 103 to rotate, driving the scraper 104, the fixing rod 105 and the cleaning roller 106 to perform circular motion. At the same time, the gear 110 and the gear 2 112 interact with each other to realize reverse rotation. The threaded sleeve 113 and the threaded sleeve 2 114 cooperate to push the threaded rod 115 up, thereby pushing the filter 123 up. When the filter 123 contacts the scraper 104 and the cleaning roller 106, the electromagnet 118 attracts the iron core 121 to move the connecting column 116 while the filter 123 remains stationary. The cleaning roller 106 uses bristles or cleaning materials to remove pollutants on the surface of the filter 123, and the scraper 104 scrapes off strong attachments to ensure thorough cleaning. Step 3: The pollutants removed during the cleaning process are sent to the inside of the housing 201 and naturally fall to the top of the second filter 205. The second filter 205 allows the water in the impurities to penetrate and flow to the bottom of the housing 201. The drain valve 211 is automatically activated to return the excess sewage to the treatment area through the drain pipe 212, effectively reducing the water content of the pollutants and laying the foundation for the subsequent drying step; Step 4: After the hot air blower 208 draws in heated air through the air inlet 209, it delivers the hot air to the inside of the shell 201 through the air inlet pipe 210. At the same time, the motor 203 is started to drive the spiral blade 204 to rotate inside the cylinder 206, driving the pollutants to spiral upward. The air holes on the outer wall of the cylinder 206 allow the hot air to contact the moist pollutants to achieve efficient drying. Finally, the dried pollutants are smoothly discharged through the discharge port 207, which significantly reduces the weight and volume of the waste residue and reduces the disposal cost. At the same time, it avoids the corrosion of the equipment by the moist waste residue and the growth of bacteria, thereby extending the service life of the equipment.

10. A method for recovering papermaking wastewater sedimentation recovery device, using the papermaking wastewater sedimentation recovery device according to claim 9, comprising the following steps: S1: wastewater is injected into the filter tank (101) through the water inlet (107), and the filter screen 1 (123) efficiently removes solid particles in the wastewater. Waste residues accumulate on the surface of the filter screen, and the wastewater after preliminary filtration quickly flows out through the drain port (108), which can significantly shorten the wastewater treatment time; S2: starting the motor 1 (102) to drive the rotating shaft (103) to rotate, driving the scraper (104), the fixing rod (105) and the cleaning roller (106) to perform circular motion. At the same time, the gear 1 (110) and the gear 2 (112) interact with each other to achieve reverse rotation. The threaded sleeve 1 (113) and the threaded sleeve 2 (114) cooperate to push the threaded rod (115) upward, thereby pushing the filter screen 1 (123) upward. When the filter screen 1 (123) contacts the scraper (104) and the cleaning roller (106), the electromagnet (118) attracts the iron core (121), causing the connecting column (116) to move while the filter screen 1 (123) remains stationary. The cleaning roller (106) uses bristles or cleaning materials to remove pollutants on the surface of the filter screen 1 (123). The scraper (104) scrapes off strong attachments to ensure thorough cleaning. S3: The pollutants removed during the cleaning process are sent to the inside of the housing (201) and naturally fall to the top of the second filter screen (205). The second filter screen (205) allows the water in the impurities to penetrate and flow to the bottom of the housing (201). The drain valve (211) is automatically activated to return the excess sewage to the treatment area through the drain pipe (212), effectively reducing the water content of the pollutants and laying the foundation for the subsequent drying step; S4: After the hot air blower (208) draws in heated air through the air inlet (209), the hot air is transported to the inside of the housing (201) through the air inlet pipe (210). At the same time, the motor 2 (203) is started to drive the spiral blade (204) to rotate inside the cylinder (206), driving the pollutants to spiral upward. The air holes on the outer wall of the cylinder (206) allow the hot air to contact the moist pollutants, thereby achieving efficient drying. Finally, the dried pollutants are smoothly discharged through the discharge port (207), significantly reducing the weight and volume of the waste residue and reducing the disposal cost. At the same time, the moist waste residue is prevented from corroding the equipment and breeding bacteria, thereby extending the service life of the equipment.
