Description

Technical Field

[0001] This invention relates to the field of waste liquid recycling technology, specifically to a device for recycling cellulose from textile waste liquid. Background Technology

[0002] Textile production generates a large amount of wastewater, which contains a certain amount of cellulose fibers, cellulose degradation products, and unreacted cellulose raw materials, as well as dyes, auxiliaries, acids, alkalis, and fine impurities. Therefore, in order to ensure that textile wastewater meets discharge standards and to recover cellulose from the wastewater, flocculation filtration is first used in industry to recover cellulose and perform preliminary water treatment.

[0003] For example, Chinese invention patent CN113200589B discloses a layered cellulose acetate wastewater flocculation device and its flocculation method, which achieves the effect of quickly producing flocculants from flocculant powder, preventing flocculant powder from scattering, and also preventing flocculant powder from adhering to and depositing inside the stirring container. The cellulose acetate wastewater is subjected to secondary stirring and tertiary settling, so that the suspended particles in the cellulose acetate wastewater are fully flocculated, and the discharged cellulose acetate wastewater meets the discharge standards without discharging the flocculants along with it.

[0004] Based on the aforementioned patents and existing technologies, current cellulose recovery devices for textile wastewater still have the following shortcomings: Existing cellulose recovery devices treat textile wastewater by adding flocculants, but the addition of flocculants is achieved through external electrical components, which increases costs and makes it impossible to precisely control the ratio of wastewater to flocculant, thus reducing the effectiveness of subsequent recovery. In some wastewater treatment fields, although automatic flocculant addition is achieved through hydraulic drive when adding wastewater, the control precision is low, and the ratio of flocculant added automatically cannot be adjusted according to the amount of cellulose impurities in the wastewater. This makes it unsuitable for different types of textile wastewater, and its practicality needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to address the problems mentioned above, such as the higher cost of adding flocculants through external electrical components, the inability to precisely control the ratio of waste liquid to flocculant, which reduces the effectiveness of subsequent recovery, and the low control precision of existing automatic flocculant addition devices, which cannot adjust the automatic addition ratio of flocculants according to the amount of cellulose impurities in the waste liquid, thus requiring improved practicality. This invention provides a cellulose recovery device for textile waste liquid.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution: A cellulose recovery device from textile waste liquid includes a support frame, a mixing tank, a waste liquid conveying pipe, and a flocculant conveying pipe. The mixing tank is fixedly installed at the center of the top of the support frame. The waste liquid conveying pipe is connected to the top of the mixing tank. A nozzle is fixedly installed at the center of the top of the mixing tank. A gear pump is installed above the mixing tank. The gear pump is connected to the flocculant conveying pipe and the nozzle via hoses. A hydraulic drive assembly is installed inside the mixing tank in the waste liquid conveying pipe. The hydraulic drive assembly is used to achieve rotational drive through the flow of waste liquid in the waste liquid conveying pipe. A transmission assembly is installed between the hydraulic drive assembly and the gear pump. The transmission assembly is used to drive the gear pump to operate through the hydraulic drive assembly.

[0007] Furthermore, the connection between the flocculant delivery pipe and the gear pump adopts a bending design.

[0008] Furthermore, a liquid outlet pipe is fixedly installed at the center of the upper part of the mixing tank by a fixing rod. The port of the liquid outlet pipe is aligned with the port of the waste liquid conveying pipe located inside the mixing tank. The hydraulic drive assembly is installed between the port of the liquid outlet pipe and the port of the waste liquid conveying pipe. The hydraulic drive assembly includes two connecting sleeves, which are respectively fixedly fitted onto the ports of the liquid outlet pipe and the waste liquid conveying pipe. The rotating ring is limited and rotated between the connecting sleeves by bearings. The drive impeller is fixedly installed on the inner side of the rotating ring, and the fixed pulley is fixedly installed at the center of the outer side of the rotating ring.

[0009] Furthermore, the side of the liquid outlet pipe away from the hydraulic drive component is circular, and the bottom is uniformly provided with liquid outlets. The nozzle is located above the center of the gap in the circular liquid outlet pipe.

[0010] Furthermore, the transmission assembly includes a mounting shell, which is fixedly installed on the side wall at the top of the mixing tank. The assembly block is slidably connected to the inside of the mounting shell with upper and lower limits. The drive shaft is rotatably connected to the bottom of the assembly block through a bearing. The combined pulley is connected to the outside of the drive shaft and is located inside the assembly block. The belt drive is connected between the fixed pulley and the combined pulley. The fixed cover is located between the assembly block and the gear pump, and its two ends are fixedly installed to the assembly block and the gear pump respectively. The drive shaft is connected to the gear pump through a coupling inside the fixed cover.

[0011] Furthermore, the transmission assembly also includes partitions, which are fixedly installed on the periphery of the drive shaft. There are two partitions, which are symmetrically distributed on both sides of the combined pulley. There are two springs, which are respectively fixedly connected between the two partitions and the side wall of the combined pulley. The springs are wrapped around the outside of the drive shaft. The threaded rod is rotatably connected to the center of the top of the assembly block, and the threaded rod passes through the mounting shell upward and is threadedly connected to the mounting shell.

[0012] Furthermore, the combined pulley is composed of two half-pulleys with opposite conical surfaces that are staggered and inserted together, and both half-pulleys are slidably connected to the outside of the drive shaft.

[0013] Furthermore, a rotating shaft is rotatably connected to the center of the mixing tank, an upper spiral blade is fixedly installed on the outer periphery of the top of the rotating shaft, a lower scraper blade is fixedly installed on the outer periphery of the bottom of the rotating shaft, and a motor is fixedly installed at the center of the bottom of the mixing tank, the motor being drivenly connected to the rotating shaft.

[0014] Furthermore, the bottom of the mixing tank is a downwardly concave semi-circular ring, and the scraper blades are designed to be inclined and attached to the inner wall of the bottom of the mixing tank.

[0015] Furthermore, a drain head is fixedly installed at the bottom of the mixing tank. The drain head is connected to the inside of the mixing tank and is used to transport the mixed waste liquid and flocculant to the sedimentation tank through a pipeline.

[0016] The beneficial effects of this invention are as follows: 1. This invention, through the design of hydraulic drive components and transmission components, combined with the use of a gear pump to pump flocculant, achieves automatic addition of flocculant without external electrical components, utilizing hydraulic drive during waste liquid addition. This saves energy, reduces operating costs, and features a simple and effective transmission system. It ensures the synchronous addition of waste liquid and flocculant in a certain proportion, improving the subsequent recovery effect. Furthermore, it can adjust the automatic addition ratio of flocculant according to the amount of cellulose impurities in the waste liquid to suit different textile waste liquids, thus enhancing practicality.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] A preferred embodiment of the present invention for cellulose recovery from textile waste liquid will be described in detail below: Example 1: As Figures 1-5 As shown, a cellulose recovery device from textile waste liquid includes a support frame 1, a mixing tank 2, a waste liquid conveying pipe 3, and a flocculant conveying pipe 4. The mixing tank 2 is fixedly installed at the center of the top of the support frame 1. The waste liquid conveying pipe 3 is connected to the top of the mixing tank 2. A nozzle 5 is fixedly installed at the center of the top of the mixing tank 2. A gear pump 6 is installed above the mixing tank 2. The gear pump 6 is connected to the flocculant conveying pipe 4 and the nozzle 5 through flexible hoses. This allows the waste liquid to enter the interior of the mixing tank 2 through the waste liquid conveying pipe 3. Simultaneously, when the gear pump 6 is running, it pumps the flocculant through the flocculant conveying pipe 4 to the nozzle 5, and then sprays it into the interior of the mixing tank 2 through the nozzle 5, thereby mixing the waste liquid and the flocculant. The design of the flexible hoses between the gear pump 6 and the flocculant conveying pipe 4 and the nozzle 5 allows the gear pump 6 to move up and down while pumping the flocculant.

[0021] A hydraulic drive assembly 7 is installed inside the mixing tank 2 within the waste liquid delivery pipe 3. The hydraulic drive assembly 7 is used to achieve rotational drive through the flow of waste liquid in the waste liquid delivery pipe 3. A transmission assembly 8 is installed between the hydraulic drive assembly 7 and the gear pump 6. The transmission assembly 8 drives the gear pump 6 through the hydraulic drive assembly 7. This ensures that as the waste liquid enters the mixing tank 2 through the waste liquid delivery pipe 3, it drives the rotation of the hydraulic drive assembly 7, which in turn drives the gear pump 6 through the transmission assembly 8. This allows the gear pump 6 to pump flocculant into the mixing tank 2. Thus, flocculant is automatically added through hydraulic drive during waste liquid addition. The faster the waste liquid flows during addition, the faster the flow rate of the gear pump 6 to pump the flocculant, thereby achieving a certain ratio of waste liquid to flocculant addition.

[0022] Furthermore, such as Figure 3 As shown, the connection between the flocculant delivery pipe 4 and the gear pump 6 adopts a bent design. This bent design of the flocculant delivery pipe 4 buffers the flocculant and increases the friction between the flocculant and the inner wall of the pipe 4. This prevents the flocculant from flowing and creating voids inside the pipe 4 when the gear pump 6 stops running, ensuring stable pumping of the flocculant and improving the accuracy of flocculant dosage.

[0023] like Figures 5-7As shown, a rotating shaft 10 is rotatably connected to the center of the mixing tank 2. An upper spiral blade 11 is fixedly installed on the outer periphery of the top of the rotating shaft 10, and a lower scraper blade 12 is fixedly installed on the outer periphery of the bottom of the rotating shaft 10. A motor 13 is fixedly installed at the center of the bottom of the mixing tank 2, and the motor 13 is connected to the rotating shaft 10 for transmission. The motor 13 drives the rotating shaft 10 to rotate, which in turn drives the upper spiral blade 11 and the lower scraper blade 12 to rotate inside the mixing tank 2, thereby achieving the mixing of waste liquid and flocculant inside the mixing tank 2.

[0024] like Figure 7 As shown, the bottom of the mixing tank 2 is a downward-concave semi-circular ring. The bottom scraper blade 12 is designed with an incline and adheres to the inner wall of the bottom of the mixing tank 2. During mixing, the incline design of the bottom scraper blade 12 prevents cellulose impurities in the waste liquid from settling and adhering to the wall, while pushing the cellulose impurities upward, allowing them to better mix and react with the flocculant. When discharging downward, the reverse rotation of the bottom scraper blade 12 pushes the generated flocs downward, facilitating their discharge and preventing them from adhering to the inner wall of the bottom of the mixing tank 2.

[0025] like Figure 4 As shown, a drain head 14 is fixedly installed at the bottom of the mixing tank 2. The drain head 14 is connected to the inside of the mixing tank 2 and is used to transport the mixed waste liquid and flocculant to the sedimentation tank through a pipeline. The sedimentation tank can be fixedly installed below the mixing tank 2 by a support frame 1. The mixed waste liquid and flocculant are transported downward to the inside of the sedimentation tank through the drain head 14, where they are better flocculated into clumps. This avoids the rapid rotation of the upper spiral blade 11 and the lower scraper blade 12 in the mixing tank 2, which would break up the flocculated clumps, thus facilitating flocculation.

[0026] Working principle: During use, the waste liquid is transported to the inside of the mixing tank 2 through the waste liquid delivery pipe 3. Through the cooperation of the hydraulic drive component 7 and the transmission component 8, the waste liquid is transported to the inside of the mixing tank 2 through the waste liquid delivery pipe 3, which drives the gear pump 6 to pump the flocculant into the inside of the mixing tank 2, thereby realizing the synchronous addition of waste liquid and flocculant in a certain proportion.

[0027] After the waste liquid and flocculant are added into the mixing tank 2, the rotating shaft 10 is driven by the motor 13 to rotate, which in turn drives the upper spiral blade 11 and the lower scraper blade 12 to rotate, so as to mix and stir the waste liquid and flocculant inside the mixing tank 2, which is beneficial to the reaction between the flocculant and the cellulose impurities in the waste liquid.

[0028] After the flocculant and waste liquid are mixed, the mixture is then transported to the interior of the settling tank through the drain head 14 to complete the flocculation and agglomeration. After filtration and dehydration, the cellulose is recovered and the waste liquid is initially treated.

[0029] Example 2: The principle of achieving synchronous addition of waste liquid and flocculant in a certain proportion through the cooperation of hydraulic drive component 7 and transmission component 8 is as follows: like Figures 8-13 As shown, a liquid outlet pipe 9 is fixedly installed at the center of the upper part of the mixing tank 2 by a fixing rod. The port of the liquid outlet pipe 9 is aligned with the port of the waste liquid conveying pipe 3 inside the mixing tank 2. The hydraulic drive assembly 7 is installed between the port of the liquid outlet pipe 9 and the port of the waste liquid conveying pipe 3. This allows the waste liquid conveying pipe 3 and the liquid outlet pipe 9 to be independently fixed relative to the mixing tank 2, which facilitates the installation of the hydraulic drive assembly 7 while ensuring the stability of the hydraulic drive assembly 7 installed between the waste liquid conveying pipe 3 and the liquid outlet pipe 9.

[0030] The hydraulic drive assembly 7 includes two connecting sleeves 701, which are respectively fixedly fitted onto the aligning ends of the outlet pipe 9 and the waste liquid conveying pipe 3. A rotating ring 702 is rotatably connected between the connecting sleeves 701 via bearings. A drive impeller 703 is fixedly installed inside the rotating ring 702, and a fixed pulley 704 is fixedly installed at the center of the outer side of the rotating ring 702. Therefore, when the waste liquid in the waste liquid conveying pipe 3 reaches the outlet pipe 9 and is discharged through the hydraulic drive assembly 7, the flow of the waste liquid drives the drive impeller 703 to rotate, which in turn drives the rotating ring 702 and the fixed pulley 704 fixedly installed on the outer side of the rotating ring 702 to rotate.

[0031] Furthermore, such as Figures 8-9 As shown, the side of the outlet pipe 9 away from the hydraulic drive component 7 is annular, and outlets are evenly distributed at the bottom. The nozzle 5 is located above the center of the gap in the annular outlet pipe 9. This allows the waste liquid entering the outlet pipe 9 to be discharged downwards through the outlets at the bottom into the mixing tank 2, preventing the waste liquid from impacting the side wall of the mixing tank 2. At the same time, as the waste liquid is discharged downwards into the mixing tank 2, the flocculant sprayed downwards from the nozzle 5 can be simultaneously discharged downwards into the mixing tank 2 from the center of the waste liquid, which is beneficial for the initial mixing of the flocculant and the waste liquid and reduces the difficulty of subsequent mixing.

[0032] like Figures 14-17As shown, the transmission assembly 8 includes a mounting housing 801, which is fixedly mounted on the side wall at the top of the mixing tank 2. An assembly block 802 is slidably connected to the interior of the mounting housing 801 with upper and lower limits. A drive shaft 803 is rotatably connected to the bottom of the assembly block 802 via bearings. A combined pulley 804 is connected to the outside of the drive shaft 803 and is located inside the assembly block 802. A belt 805 drives the combination pulley 804 between the fixed pulley 704 and the combined pulley 804. Therefore, when the fixed pulley 704 rotates, the belt 805 can drive the combined pulley 804 and the drive shaft 803 to rotate.

[0033] The fixed cover 806 is located between the assembly block 802 and the gear pump 6, and its two ends are fixedly installed to the assembly block 802 and the gear pump 6 respectively. The drive shaft 803 is connected to the gear pump 6 via a coupling inside the fixed cover 806. The fixed cover 806 is used to fix the gear pump 6 to the assembly block 802, while the drive shaft 803 is connected to the gear pump 6 via a coupling. When the drive shaft 803 rotates, it can drive the gear pump 6 to operate.

[0034] Working principle: When the waste liquid in the waste liquid conveying pipe 3 passes through the hydraulic drive component 7 to the outlet pipe 9 and is discharged into the mixing tank 2, the flow of the waste liquid can drive the drive impeller 703 to rotate, which in turn drives the rotating ring 702 and the fixed belt pulley 704 fixedly installed on the outside of the rotating ring 702 to rotate.

[0035] When the fixed pulley 704 rotates, the belt 805 drives the combined pulley 804 and the drive shaft 803 to rotate. When the drive shaft 803 rotates, the gear pump 6 is driven to operate through the coupling, so that the gear pump 6 can pump the flocculant into the mixing tank 2.

[0036] The faster the waste liquid flows in the waste liquid conveying pipe 3, the faster the impeller 703 drives the rotating ring 702 and the fixed pulley 704 to rotate. Consequently, the belt 805 drives the combined pulley 804 and the drive shaft 803 to rotate faster. Under the action of the drive shaft 803, the flow rate of the flocculant pumped by the gear pump 6 into the mixing tank 2 will also increase, thereby achieving the synchronous addition of waste liquid and flocculant in a certain proportion.

[0037] Example 3: Further, such as Figures 17-19As shown, the transmission assembly 8 also includes a partition plate 807, which is fixedly installed on the periphery of the drive shaft 803. There are two partition plates 807, symmetrically distributed on both sides of the combined pulley 804. There are also two springs 808, which are fixedly connected between the two partition plates 807 and the sidewalls of the combined pulley 804, respectively, and the springs 808 wrap around the outside of the drive shaft 803. The combined pulley 804 is composed of two cone-shaped, staggered half-pulleys, both of which are slidably connected to the outside of the drive shaft 803. Therefore, while the drive shaft 803 and the combined pulley 804 can rotate synchronously, the two cone-shaped, staggered half-pulleys of the combined pulley 804 can move towards or away from each other under the pull of the springs 808 and the belt 805, thereby changing the transmission radius of the combined pulley 804 and the belt 805. (It should be noted that...) Figure 19 As shown, the drive shaft 803 is composed of three fixedly connected sections. The middle section has a groove on its outer periphery for a limited sliding connection with the combined pulley 804. The three-section splicing design of the drive shaft 803 facilitates the assembly of the combined pulley 804 and the drive shaft 803.

[0038] The threaded rod 809 is rotatably connected to the center of the top of the assembly block 802, and extends upward through the mounting shell 801, where it is threadedly connected. Therefore, by rotating the threaded rod 809, utilizing its threaded connection to the mounting shell 801 and its rotatable connection to the assembly block 802, the assembly block 802 can be moved up and down within the mounting shell 801.

[0039] Working principle: When it is necessary to adjust the ratio of waste liquid and flocculant added simultaneously according to the different cellulose impurity content in the waste liquid.

[0040] First, the assembly block 802 is moved up and down inside the mounting housing 801 by rotating the threaded rod 809. When the assembly block 802 moves upward inside the mounting housing 801, it drives the combined pulley 804 upward away from the fixed pulley 704. Then, under the pull of the belt 805, it pushes the combined pulley 804 to compress the spring 808, causing them to move apart. At this time, the transmission radius of the combined pulley 804 and the belt 805 decreases, thus increasing the rotation speed of the fixed pulley 704 and the drive shaft 803 via the belt 805. Conversely, when the assembly block 802 moves downward inside the mounting housing 801, it drives the combined pulley 804 downward towards the fixed pulley 704. This reduces the tension of the belt 805 on the combined pulley 804, causing the combined pulley 804 to move towards the center under the action of the spring 808. At this time, the transmission radius of the combined pulley 804 and the belt 805 increases, thus slowing down the rotation speed of the fixed pulley 704 and the drive shaft 803 via the belt 805.

[0041] Therefore, by rotating the threaded rod 809 to adjust the position of the assembly block 802 inside the mounting shell 801, the transmission ratio between the fixed pulley 704 and the combined pulley 804 can be adjusted, thereby adjusting the ratio of simultaneous addition of waste liquid and flocculant to suit different textile waste liquids and improve practicality.
