Description

Technical Field

[0001] This utility model belongs to the technical field of wastewater recycling devices, and in particular relates to a recycling device for wastewater from parchment production. Background Technology

[0002] The wastewater recycling system for parchment production is a specialized equipment system for treating wastewater containing pollutants generated during parchment production and realizing the recycling and reuse of water resources. Its core function is to remove impurities such as fiber residue, organic matter, and suspended solids from the wastewater through processes such as filtration, sedimentation, oxidation, and membrane separation, thereby reducing the concentration of pollutants in the wastewater and enabling the treated water to meet the standards for reuse in production or discharge. This not only reduces water consumption but also reduces the environmental impact of wastewater discharge.

[0003] However, during the use of existing devices, after the initial filtration of wastewater, the separated solid impurities tend to adhere to the surface of the filter components or scatter inside the equipment, making it difficult for them to automatically collect in the designated area, thus requiring manual assistance for cleaning. Utility Model Content

[0004] The purpose of this utility model is to provide a wastewater recycling device for parchment production. By setting up a filtration section, it solves the problem that after the initial filtration of wastewater, the separated solid impurities are easily attached to the surface of the filtration components or scattered inside the equipment, making it difficult for them to automatically collect in the designated area, thus requiring manual assistance for cleaning.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a wastewater recycling device for parchment production, comprising a base plate and further comprising: a filter section disposed on top of the base plate; a configuration section disposed on top of the base plate; the filter section comprising a filter assembly mounted on top of the base plate; and a drive assembly mounted on the filter assembly; the filter assembly comprising a filter box fixedly connected to the top of the base plate, the filter box having a waste outlet on its front side, a filter plate hinged inside the filter box, rotating blocks rotatably connected to both sides of the filter plate, and a fixed connection on the front side of the filter box. A fixed plate is provided, on which two sliding rods are slidably connected. The bottom ends of the two sliding rods are fixedly connected to two rotating blocks, and the top ends of the two sliding rods are fixedly connected to a top plate. Springs are wound around the outer walls of the two sliding rods. One end of each spring is fixedly connected to the fixed plate, and the other end of each spring is fixedly connected to the top plate. A collection component is provided on the filter box. The end of the filter plate near the waste inlet extends outside the waste inlet and is slidably connected to the waste inlet. The collection component includes a collection box slidably connected to the front of the filter box. The collection boxes are adapted to the waste inlet and the filter plate.

[0006] Furthermore, the configuration unit includes a processing component mounted on top of the base plate; and a recycling component mounted on top of the base plate.

[0007] Furthermore, the drive assembly includes two U-shaped plates fixedly connected to the top of the fixed plate, with a rotating shaft rotatably connected to the two U-shaped plates. A cam is fixedly connected to the outer wall of the rotating shaft, and a drive component is provided on the rotating shaft. The outer wall of the cam contacts the top plate. The drive component includes a motor fixedly connected to the corresponding U-shaped plate. The output shaft of the motor is fixedly connected to the rotating shaft through a coupling, and the motor is located on the right U-shaped plate.

[0008] Furthermore, the processing assembly includes an air flotation machine fixedly connected to the top of the base plate, a liquid pump is provided on the right side of the filter box, a delivery pipe is fixedly connected to the right end of the liquid pump, and the end of the delivery pipe is fixedly connected to the air flotation machine.

[0009] Furthermore, the recovery assembly includes a bioreactor fixedly connected to the top of the base plate, a second liquid pump is provided on the right side of the air flotation machine, a second conveying pipe is fixedly connected to the right end of the second liquid pump, the end of the second conveying pipe is fixedly connected to the bioreactor, a reagent tube is fixedly connected to the top of the bioreactor, a discharge pipe is fixedly connected to the bottom of the bioreactor, a valve is provided on the discharge pipe, an ultrafiltration device is provided at the bottom end of the discharge pipe, and the reagent tube communicates with the bioreactor.

[0010] This utility model has the following beneficial effects: 1. By setting up a filtration section, wastewater can be discharged into the filter box during pretreatment. After being filtered by the internal filter plate, the wastewater is collected at the bottom of the box. During the filtration process, the motor is started. The motor drives the cam to rotate through the shaft. When the cam's protrusion contacts the top plate, the top plate is guided by two sliding rods. In conjunction with the rotating block on the filter plate, the filter plate moves downward. At the same time, the spring on the outer wall of the sliding rod is compressed to accumulate elastic potential energy. When the cam protrusion rotates away from the top plate, the top plate, under the guidance of the sliding rod and the spring's restoring thrust, drives the filter plate to move upward. Through the continuous compression and release of the top plate by the cam, the filter plate vibrates up and down in the waste port, causing the solid impurities trapped on the surface to fall into the waste port and finally be collected in the collection box, realizing the automatic separation and collection of solid impurities without the need for manual cleaning. 2. By setting up the configuration unit, when the pretreated wastewater requires further treatment, liquid pump one can be started to send the wastewater in the filter box into the air flotation machine through the conveying pipe one to separate suspended oil and fine fibers to reduce the load on subsequent treatment. Then, liquid pump two is started to send the treated liquid into the bioreactor through the conveying pipe two. PAC, PAM and other agents are added through the reagent pipe to remove colloids and organic matter in the water. Then, the bioreactor is started to decompose the dissolved organic pollutants COD and BOD in the wastewater. Finally, the wastewater is treated by the ultrafiltration device to obtain qualified reclaimed water. In addition, the fibers collected in the initial filtration stage can be reused for papermaking raw materials, and the salts concentrated by the ultrafiltration device can be further processed and recycled. This achieves both efficient and deep purification of wastewater and the goal of resource recycling and reuse.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 As shown, this utility model is a wastewater recycling device for parchment production, including a base plate 1, and further including: a filter section 2, which is disposed on the top of the base plate 1; and a configuration section 3, which is disposed on the top of the base plate 1.

[0017] The filter section 2 includes a filter assembly 21, which is mounted on the top of the base plate 1; and a drive assembly 22, which is mounted on the filter assembly 21. The filter assembly 21 includes a filter box 211 fixedly connected to the top of the base plate 1. A waste port 212 is provided on the front of the filter box 211. A filter plate 213 is hinged inside the filter box 211. Rotating blocks 214 are rotatably connected to both sides of the filter plate 213. A fixing plate 215 is fixedly connected to the front of the filter box 211. Two sliding rods 216 are slidably connected to the fixing plate 215. The bottom ends of the two sliding rods 216 are fixedly connected to the two rotating blocks 214. A top plate 217 is fixedly connected to the top ends of the two sliding rods 216. Springs 218 are wound around the outer walls of the two sliding rods 216. One end of each of the two springs 218 is fixedly connected to the fixed plate 215, and the other end of each of the two springs 218 is fixedly connected to the top plate 217. A collection component is provided on the filter box 211. One end of the filter plate 213 near the waste port 212 extends to the outside of the waste port 212 and is slidably connected to the waste port 212. The drive assembly 22 includes two U-shaped plates 221 fixedly connected to the top of the fixed plate 215. A rotating shaft 223 is rotatably connected to the two U-shaped plates 221. A cam 224 is fixedly connected to the outer wall of the rotating shaft 223. A drive component is provided on the rotating shaft 223. The outer wall of the cam 224 contacts the top plate 217. The collection component includes a collection box 219 slidably connected to the front of the filter box 211. The collection boxes 219 are all connected to the waste port 212. Adapted to the filter plate 213, the driving component includes a motor 222 fixedly connected to the corresponding U-shaped plate 221. The output shaft of the motor 222 is fixedly connected to the rotating shaft 223 via a coupling. The motor 222 is located on the U-shaped plate 221 on the right side. By setting the filter section 2, when pre-treating wastewater, it can be discharged into the filter box 211. After being filtered by the filter plate 213 inside the box, the wastewater is collected at the bottom of the filter box 211. During the filtration process, the motor 222 can also be started. The motor 222 will drive the cam 224 to rotate via the rotating shaft 223. With the special shape of the cam 224, when the protruding part rotates to contact the top plate 217, the top plate 217 will be guided by two sliding rods 216 and cooperate with two on the filter plate 213. Rotating the rotating block 214 causes the filter plate 213 to move downwards. As the top plate 217 moves downwards, it also compresses the springs 218 on the outer walls of the two sliding rods 216, allowing them to accumulate elastic potential energy for subsequent reset. When the protrusion on the cam 224 rotates away from the top plate 217, the top plate 217, guided by the sliding rods 216 and driven by the reset thrust of the springs 218, causes the filter plate 213, which is rotatably connected to it, to move upwards. Through the continuous compression and release of the top plate 217 by the cam 224, the filter plate 213 can vibrate up and down in the waste port 212, causing the solid impurities trapped on the surface to fall into the waste port 212 and finally be collected in the collection box 219. This setting can realize the automatic separation and collection of solid impurities without the need for manual cleaning.

[0018] Configuration unit 3 includes a processing component 31, which is mounted on top of base plate 1; and a recovery component 32, which is also mounted on top of base plate 1. The processing component 31 includes an air flotation machine 311 fixedly connected to the top of base plate 1. A liquid pump 312 is located on the right side of filter box 211, and a delivery pipe 313 is fixedly connected to the right end of the liquid pump 312. The end of the delivery pipe 313 is fixedly connected to the air flotation machine 311. The recovery component 32 includes a... A liquid pump 322 is installed on the right side of the bioreactor 321 and the flotation machine 311. A delivery pipe 323 is fixedly connected to the right end of the liquid pump 322. The end of the delivery pipe 323 is fixedly connected to the bioreactor 321. A reagent pipe 324 is fixedly connected to the top of the bioreactor 321. A feed pipe 325 is fixedly connected to the bottom of the bioreactor 321. A valve 326 is installed on the feed pipe 325. An ultrafiltration device 327 is installed at the bottom end of the feed pipe 325. 24 is connected to the bioreactor 321. By setting up configuration unit 3, when the pretreated wastewater needs to be further treated, liquid pump 312 can be started to transport the pretreated wastewater in filter box 211 to air flotation machine 311 through conveying pipe 313. The air flotation machine 311 separates suspended oil and fine fibers, reducing the load of subsequent treatment. The treated liquid is then pumped by liquid pump 322 and sent into bioreactor 321 through conveying pipe 323. After the liquid enters bioreactor 321, PAC, PAM and other agents can be added through reagent pipe 324 to remove colloids and organic matter in the water. Then, bioreactor 321 is started to decompose dissolved organic pollutants COD and BOD in the wastewater. Finally, the ultrafiltration device 327 is used to obtain qualified reclaimed water. In addition, the fibers collected in the initial filtration stage can be reused for papermaking raw materials, and the salts concentrated by ultrafiltration device 327 can be further processed and recycled. This setup can achieve both efficient deep purification of wastewater and the goal of resource recycling and reuse.

[0019] Dissolved air flotation unit 311: Parchment paper wastewater has a complex composition and high content of suspended solids and organic matter. For recycling and treatment, the QL-QFG series dissolved air flotation unit (such as the QL-QFG-5 and QL-QFG-50 models with a processing capacity of 1-100m³ / h) can be selected. It releases microbubbles by pressurizing dissolved air, adsorbing pollutants such as fibers and oils in the wastewater to form air flotation bodies that float to the surface and separate. It can effectively reduce COD and BOD values, reduce the load on subsequent treatment, and the equipment has a small footprint, is easy to operate and maintain, and is suitable for the wastewater recycling needs of parchment paper production of different scales.

[0020] Bioreactor 321: Parchment wastewater is rich in recalcitrant organic matter and lignin. For recycling and treatment, Biobed® Advanced EGSB / UASB anaerobic reactors (such as 150-9000m³ models) or Biyuan MBR membrane bioreactors (such as modular models suitable for small and medium scales) can be selected. The former efficiently degrades COD through granular sludge and converts it into recyclable biogas, while the latter relies on the synergistic effect of membrane separation and biodegradation, achieving a COD removal rate of over 90% and a BOD removal rate of over 95%. Both have the advantages of compact structure, small footprint, and low operating cost, and can be adapted to different treatment scales. The treated effluent can meet the requirements for reuse or discharge standards, which helps the resource recycling of parchment production.

[0021] Ultrafiltration Unit 327: Parchment wastewater contains fine fibers, colloids, and some dissolved organic matter. For recycling and treatment, the UF-8040 series ultrafiltration unit (such as UF-8040-LP, UF-8040-HR, etc. with a single membrane module processing capacity of 1-5 m³ / h) can be selected. It uses an ultrafiltration membrane with a pore size of 0.01-0.1 μm to intercept suspended particles and large molecular impurities in the wastewater, while retaining small molecular beneficial components. After treatment, the water quality is clear and the turbidity is greatly reduced, and it can be directly reused in the production cleaning process.

[0022] It should be noted that the control of motor 222, air flotation machine 311, liquid pump one 312, bioreactor 321, liquid pump two 322 and ultrafiltration device 327 in this application can all be achieved by using the program set in the control panel and inputting relevant parameters as needed for automated control. The setting of this control method can be realized by existing technology, such as PLC.

[0023] One specific application of this embodiment is as follows: When pretreating wastewater, it can be discharged into the filter box 211. After being filtered by the filter plate 213 inside the box, the wastewater is collected at the bottom of the filter box 211. During the filtration process, the motor 222 can also be started. The motor 222 will drive the cam 224 to rotate through the rotating shaft 223. With the special shape of the cam 224, when the protruding part rotates to contact the top plate 217, the top plate 217 will be guided by the two sliding rods 216 and cooperate with the two rotating blocks 214 on the filter plate 213, thereby driving... The filter plate 213 moves downward, and as the top plate 217 moves downward, it also compresses the springs 218 on the outer walls of the two slide rods 216, allowing them to accumulate elastic potential energy for subsequent reset. When the protrusion on the cam 224 rotates away from the top plate 217, the top plate 217, guided by the slide rods 216 and driven by the reset thrust of the springs 218, moves the filter plate 213, which is rotatably connected to it, upward. Through the continuous compression and release of the top plate 217 by the cam 224, the filter plate 213 can vibrate up and down within the waste inlet 212, causing the solid residue trapped on the surface to be removed. Solid impurities are shaken off to waste inlet 212 and finally collected in collection box 219. This setup enables automatic separation and collection of solid impurities without manual cleaning. When the pretreated wastewater requires further treatment, liquid pump 312 can be started to transport the pretreated wastewater in filter box 211 to flotation machine 311 via conveying pipe 313. The flotation machine 311 separates suspended oils and fine fibers, reducing the load on subsequent treatment. The treated liquid is then pumped by liquid pump 322 and sent to bioreactor 321 via conveying pipe 323. After the wastewater enters the bioreactor 321, PAC, PAM and other reagents can be added through the reagent tube 324 to remove colloids and organic matter from the water. Then, the bioreactor 321 is started to decompose dissolved organic pollutants COD and BOD in the wastewater. Finally, the wastewater is treated by the ultrafiltration device 327 to obtain qualified reclaimed water. In addition, the fibers collected in the initial filtration stage can be reused as papermaking raw materials, and the salts concentrated by the ultrafiltration device 327 can be further processed and recycled. This setup can achieve both efficient and deep purification of wastewater and the goal of resource recycling and reuse.
