Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and specifically, to a fiber rotary disk filter device. Background Art

[0002] A fiber rotary disk filter device can be used for sewage treatment. The fiber rotary disk filter device can effectively remove suspended solids, colloidal substances, etc. in sewage, thereby improving the effluent quality. At the same time, a dosing device can be used to preliminarily purify the sewage, so that pollutants undergo reactions such as coagulation and precipitation, thereby enabling the fiber rotary disk filter device to better remove suspended solids, colloidal substances, etc. in sewage.

[0003] There are some drawbacks in the existing devices during use. For example, the existing fiber rotary disk filter device and dosing device are two independent entities and cannot effectively cooperate during the sewage treatment process. The fiber rotary disk filter device and dosing device bear too much burden during the separate sewage treatment process and cannot effectively treat the sewage. Moreover, the existing dosing device cannot dose quantitatively. The inability to dose quantitatively will make it difficult to accurately control the dosing amount of the reagent, resulting in large fluctuations in the treated water quality and inability to meet stable water quality standards. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fiber rotary disk filter device to solve the problems that the fiber rotary disk filter device and the dosing device cannot cooperate and the existing dosing device cannot dose quantitatively.

[0005] The utility model provides the following technical solution: A fiber rotary disk filter device includes a filter tank. Opposite outer walls of the filter tank are respectively fixedly connected with a water inlet pipe and a water outlet pipe. Three sewage discharge grooves are formed in the inner bottom wall of the filter tank. Sewage discharge pipes are respectively fixedly connected to the outer wall of one side of the filter tank corresponding to the three sewage discharge grooves. The three sewage discharge pipes are respectively communicated with the corresponding sewage discharge grooves. Support blocks are respectively fixedly connected to both sides of the inner bottom wall of the filter tank. The two support blocks are symmetrically arranged. A filter assembly is arranged on the support blocks. A cleaning assembly is arranged on the filter tank. Two mounting blocks are fixedly connected to one side of the upper end surface of the filter tank. A dosing assembly is arranged on the mounting blocks.

[0006] In the above solution, the water inlet pipe is responsible for introducing the sewage to be treated into the filter tank, and the water outlet pipe is responsible for discharging the filtered sewage. This design improves the continuity and efficiency of the filtration process. The sewage discharge grooves can collect and concentrate the waste such as impurities and sediments generated during the filtration process, avoiding the accumulation and diffusion of these wastes in the filter tank. The sewage discharge pipes enable the wastes to be conveniently discharged from the filter tank through the sewage discharge pipes.

[0007] Preferably, as the above technical solution, the filtering component includes mounting holes respectively formed in two supporting blocks. An outlet rotating pipe is rotatably sleeved inside the two mounting holes. One end of the outlet rotating pipe is closed. The open end of the outlet rotating pipe penetrates through one side of the filtering tank and is rotatably connected to the filtering tank. The open end of the outlet rotating pipe is rotatably connected to the outlet pipe. A plurality of groups of water outlet holes are arrayed on the outer side of the outlet rotating pipe. Fiber filtering rotating discs are respectively fixedly sleeved at positions corresponding to the plurality of groups of water outlet holes on the outer side of the outlet rotating pipe. Filter cloths are respectively mounted on the outer sides of both ends of the plurality of groups of fiber filtering rotating discs. The plurality of groups of fiber filtering rotating discs communicate with the outlet rotating pipe through corresponding water outlet holes.

[0008] In the above solution, under the action of gravity and pressure, the sewage penetrates through the filter cloth and enters the inside of the fiber filtering rotating disc. The porous structure and adsorbability of the filter cloth can effectively intercept impurities such as suspended solids and organic matters in the sewage. The filtered clear water enters the outlet rotating pipe through the water outlet holes. Since the outlet rotating pipe is rotating, this rotation helps to promote the uniform distribution of the sewage on the filter cloth and improve the filtering efficiency. The clear water gathers in the outlet rotating pipe and flows out from the outlet pipe through the open end of the outlet rotating pipe. Since the outlet rotating pipe and the outlet pipe are rotatably connected, the rotation of the outlet rotating pipe will not affect the normal discharge of the clear water.

[0009] Preferably, as the above technical solution, a first transmission wheel is fixedly sleeved on the outer side of the closed end of the outlet rotating pipe. One side of the upper end surface of the filtering tank corresponding to the closed end of the outlet rotating pipe is fixedly connected with a driving motor. The output end of the driving motor is fixedly connected with a rotating shaft. A second transmission wheel is fixedly sleeved on the outer side of the rotating shaft. A belt is sleeved on the outer sides of the first transmission wheel and the second transmission wheel. The first transmission wheel and the second transmission wheel are connected by belt transmission.

[0010] In the above solution, the driving motor drives the rotating shaft to rotate. When the rotating shaft rotates, the second transmission wheel rotates accordingly. The rotation of the second transmission wheel drives the first transmission wheel to rotate through the belt. The rotation of the first transmission wheel drives the outlet rotating pipe to rotate. This rotation helps to optimize the filtering effect, make the sewage distribute more evenly on the filter cloth, and improve the filtering efficiency.

[0011] As an optimization of the above technical solution, the cleaning component includes a support frame fixedly connected to the inner wall of one side of the filtration tank. Cleaning suction blocks are respectively arranged on both sides of multiple fiber filtration rotating discs. One side of multiple cleaning suction blocks close to the support frame is fixedly connected to the support frame. One side of the upper end surfaces of multiple cleaning suction blocks close to the filter cloth is respectively fixedly connected with a scraper. The scraping surfaces of multiple scrapers are attached to the outer surface of the filter cloth. The bottom ends of multiple cleaning suction blocks are respectively fixedly connected with cleaning water pipes. One ends of multiple cleaning water pipes far away from the cleaning suction blocks are fixedly connected with a connecting water pipe. Both ends of the connecting water pipe are closed. The cleaning water pipes are communicated with the cleaning suction blocks and the connecting water pipe. The connecting water pipe is fixedly connected to the inner wall of one side of the filtration tank. A water suction pipe is arranged at the position of the outer wall of one side of the filtration tank corresponding to the connecting water pipe. One end of the water suction pipe close to the connecting water pipe penetrates through one side of the filtration tank and is fixedly connected with the filtration tank. The water suction pipe is communicated with the connecting water pipe. A water suction pump is arranged on one side of the water suction pipe. The output end of the water suction pump is communicated with the water suction pipe. The water suction pump is fixedly connected to the outer wall of one side of the filtration tank.

[0012] In the above solution, after a long time of filtration, there will be accumulated dirt or impurities on the surface of the filter cloth. The rotation of the fiber filtration rotating disc drives the rotation of the filter cloth. The relative movement between the rotation of the filter cloth and the fixed scraper can more effectively scrape off the accumulated dirt or impurities on the filter cloth. Compared with static cleaning, dynamic cleaning can cover the surface of the filter cloth more comprehensively, reduce cleaning dead corners, and improve cleaning efficiency. Thus, the scraper scrapes off the accumulated dirt or impurities on the filter cloth. The negative pressure is generated by the operation of the water suction pump. The scraped dirt and impurities are sucked into the suction channel in the cleaning suction block by the negative pressure generated by the water suction pump. The dirt and impurities enter the connecting water pipe through the cleaning water pipe and are then discharged through the water suction pipe.

[0013] As an optimization of the above technical solution, the chemical dosing component includes a chemical dosing tank fixedly connected to the tops of two mounting blocks. A chemical dosing chamber is opened at the top of the chemical dosing tank. A chemical dosing hole is opened at the bottom of the chemical dosing tank. The chemical dosing hole is communicated with the chemical dosing chamber. A moving block is slidably connected between the two mounting blocks. A communication hole is opened on the moving block. A chemical dosing pipe is fixedly connected to the position of the bottom end of the moving block corresponding to the communication hole. The chemical dosing pipe is communicated with the chemical dosing hole through the communication hole. A chemical dosing cover is arranged at the bottom end of the chemical dosing pipe. The lower end surface of the chemical dosing cover abuts against the upper end surface of the filtration tank. A hinge is fixedly connected to one side of the chemical dosing pipe and the chemical dosing cover. The chemical dosing pipe and the chemical dosing cover are hinged through the hinge. A connecting block is fixedly connected to the lower end surface of the moving block. A cylinder is arranged on one side of the connecting block far away from the chemical dosing pipe. The cylinder is fixedly connected to the upper end surface of the filtration tank. The output end of the cylinder is fixedly connected to one outer wall of the connecting block.

[0014] In the above solution, when the moving block is in the non-dosing position, the dosing pipe is connected to the dosing hole through the communication hole and quantitatively receives the medicine in the dosing tank. Since the dosing cover abuts against the upper end face of the filtration tank, the dosing cover is in the closed state. When it is necessary to dose the filtration tank, the cylinder drives the connecting block to move the moving block. The movement of the moving block drives the dosing pipe to move. When the dosing pipe moves to the dosing position, the dosing cover no longer abuts against the upper end face of the filtration tank. The weight of the medicine causes the dosing cover to open, allowing the medicine to enter the filtration tank. After dosing, the cylinder drives the connecting block to move the moving block. The movement of the moving block drives the dosing pipe to move to the non-dosing position. During the movement, the dosing cover abuts against the upper end face of the filtration tank again. This abutting action causes the dosing cover to close automatically, thus preventing the outflow of the medicine during the non-dosing period.

[0015] As a preference of the above technical solution, limiting sliders are respectively and fixedly connected to the outer walls of the opposite sides of the moving block. Limiting chutes adapted to the sizes of the limiting sliders are respectively and horizontally formed in the inner walls of the opposite sides of the two mounting blocks at positions corresponding to the limiting sliders. The moving block is slidably connected to the mounting block through the limiting sliders.

[0016] In the above solution, the cooperation between the limiting sliders and the limiting chutes ensures the stability of the moving block during the sliding process. This design prevents the moving block from shifting or shaking during the movement, ensuring the accuracy and reliability of the entire structure during the movement.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] In the present utility model, by directly installing the dosing assembly above the filtration tank, the connection between the dosing and filtration links is realized, improving the collaborative working efficiency of the entire treatment system. The design of the dosing pipe ensures that the amount of each dose is constant, avoiding the errors that may occur during manual dosing and improving the stability and reliability of water quality treatment. Through the precise drive of the cylinder, it is ensured that the dosing pipe can accurately move to the designated dosing position and non-dosing position. This mechanized control method reduces the errors of manual operation and realizes the precise control of the dosing process. Description of the Drawings

Specific implementation mode

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Embodiment 1

[0029] As Figure 1 And Figure 2As shown in the figure, the utility model provides a technical solution: a fiber rotary filter device, which includes a filter tank 10. Two opposite outer side walls of the filter tank 10 are respectively fixedly connected with a water inlet pipe 11 and a water outlet pipe 12. Three sewage discharge grooves 13 are formed on the inner bottom wall of the filter tank 10. Sewage discharge pipes 14 are respectively fixedly connected to the positions of the outer side wall of the filter tank 10 corresponding to the three sewage discharge grooves 13. The three sewage discharge pipes 14 are respectively communicated with the corresponding sewage discharge grooves 13. Two support blocks 15 are respectively fixedly connected to both sides of the inner bottom wall of the filter tank 10. The two support blocks 15 are symmetrically arranged. A filter assembly is arranged on the support blocks 15. A cleaning assembly is arranged on the filter tank 10. Two mounting blocks 16 are fixedly connected to one side of the upper end face of the filter tank 10. A chemical adding assembly is arranged on the mounting blocks 16. In the specific use process, the water inlet pipe 11 is responsible for introducing the sewage to be treated into the filter tank 10, and the water outlet pipe 12 is responsible for discharging the sewage after filtration treatment. This design improves the continuity and efficiency of the filtration process. The sewage discharge grooves 13 can collect and concentrate the waste such as impurities and sediments generated during the filtration process, avoiding the accumulation and diffusion of these wastes in the filter tank 10. The sewage discharge pipes 14 enable the wastes to be conveniently discharged from the filter tank 10 through the sewage discharge pipes 14.

[0030] As an implementation manner in this embodiment, as Figure 3 and Figure 4 shown, the filter assembly includes mounting holes 20 respectively formed on the two support blocks 15. A water outlet rotating pipe 21 is rotatably sleeved inside the two mounting holes 20. One end of the water outlet rotating pipe 21 is closed. The open end of the water outlet rotating pipe 21 penetrates through one side of the filter tank 10 and is rotatably connected to the filter tank 10. The open end of the water outlet rotating pipe 21 is rotatably connected to the water outlet pipe 12. A plurality of groups of water outlet holes 22 are arrayed on the outer side of the water outlet rotating pipe 21. Fiber filter rotating discs 23 are respectively fixedly sleeved at the positions of the outer side of the water outlet rotating pipe 21 corresponding to the plurality of groups of water outlet holes 22. Filter cloths 24 are respectively installed on the outer sides of both ends of the plurality of groups of fiber filter rotating discs 23. The plurality of groups of fiber filter rotating discs 23 are communicated with the water outlet rotating pipe 21 through the corresponding water outlet holes 22. In the specific use process, under the action of gravity and pressure, the sewage penetrates through the filter cloth 24 and enters the inside of the fiber filter rotating disc 23. The porous structure and adsorbability of the filter cloth 24 can effectively intercept impurities such as suspended solids and organic matters in the sewage. The filtered clear water enters the water outlet rotating pipe 21 through the water outlet holes 22. Since the water outlet rotating pipe 21 is rotating, this rotation helps to promote the uniform distribution of the sewage on the filter cloth 24 and improve the filtration efficiency. The clear water converges in the water outlet rotating pipe 21 and flows out from the water outlet pipe 12 through the open end of the water outlet rotating pipe 21. Since the water outlet rotating pipe 21 and the water outlet pipe 12 are rotatably connected, the rotation of the water outlet rotating pipe 21 will not affect the normal discharge of the clear water.

[0031] As an implementation manner in this embodiment, as Figure 4As shown in the figure, a first transmission wheel 30 is fixedly sleeved on the outer side of the closed end of the water outlet rotating pipe 21. On one side of the upper end surface of the filter tank 10 corresponding to the closed end of the water outlet rotating pipe 21, a driving motor 31 is fixedly connected. The output end of the driving motor 31 is fixedly connected with a rotating shaft 32. A second transmission wheel 33 is fixedly sleeved on the outer side of the rotating shaft 32. A belt 34 is sleeved on the outer sides of the first transmission wheel 30 and the second transmission wheel 33. The first transmission wheel 30 and the second transmission wheel 33 are connected by belt drive through the belt 34. In the specific use process, the rotating shaft 32 is driven to rotate by the driving motor 31. When the rotating shaft 32 rotates, the second transmission wheel 33 rotates accordingly. The rotation of the second transmission wheel 33 drives the first transmission wheel 30 to rotate through the belt 34. The rotation of the first transmission wheel 30 drives the water outlet rotating pipe 21 to rotate. This rotation helps to optimize the filtration effect, make the sewage distribute more evenly on the filter cloth 24, and improve the filtration efficiency.

[0032] As an implementation manner in this embodiment, as Figure 5 and Figure 6 shown in the figure, the cleaning component includes a support frame 40 fixedly connected to the inner wall of one side of the filter tank 10. Cleaning suction blocks 41 are respectively arranged on both sides of multiple fiber filter turntables 23. One side of the multiple cleaning suction blocks 41 close to the support frame 40 is fixedly connected to the support frame 40. On one side of the upper end surfaces of the multiple cleaning suction blocks 41 close to the filter cloth 24, scraping plates 46 are respectively fixedly connected. The scraping surfaces of the multiple scraping plates 46 are attached to the outer surface of the filter cloth 24. At the bottom ends of the multiple cleaning suction blocks 41, cleaning water pipes 42 are respectively fixedly connected. One ends of the multiple cleaning water pipes 42 far away from the cleaning suction blocks 41 are fixedly connected to a connecting water pipe 43. Both ends of the connecting water pipe 43 are closed. The cleaning water pipes 42 are communicated with the cleaning suction blocks 41 and the connecting water pipe 43. The connecting water pipe 43 is fixedly connected to the inner wall of one side of the filter tank 10. A water suction pipe 44 is arranged at the position of the outer wall of one side of the filter tank 10 corresponding to the connecting water pipe 43. One end of the water suction pipe 44 close to the connecting water pipe 43 penetrates through one side of the filter tank 10 and is fixedly connected to the filter tank 10. The water suction pipe 44 is communicated with the connecting water pipe 43. A water suction pump 45 is arranged on one side of the water suction pipe 44. The output end of the water suction pump 45 is communicated with the water suction pipe 44. The water suction pump 45 is fixedly connected to the outer wall of one side of the filter tank 10. In the specific use process, after a long time of filtration, dirt or impurities will accumulate on the surface of the filter cloth 24. The rotation of the fiber filter turntable 23 drives the filter cloth 24 to rotate. The rotation of the filter cloth 24 generates relative movement with the fixed scraping plates 46. This dynamic cleaning method can more effectively scrape off the dirt or impurities accumulated on the filter cloth 24. Compared with static cleaning, dynamic cleaning can more comprehensively cover the surface of the filter cloth 24, reduce the cleaning dead angle, and improve the cleaning efficiency. Thus, the scraping plates 46 scrape off the dirt or impurities accumulated on the filter cloth 24. Through the operation of the water suction pump 45 to generate negative pressure, the scraped dirt and impurities are sucked into the suction channel in the cleaning suction block 41 by the negative pressure generated by the water suction pump 45. The dirt and impurities enter the connecting water pipe 43 through the cleaning water pipes 42 and are discharged through the water suction pipe 44.

[0033] As an implementation mode in this embodiment, as Figure 7 shown, the medicine adding component includes a medicine adding tank 50 fixedly connected to the tops of two mounting blocks 16. A medicine adding cavity 51 is provided at the top of the medicine adding tank 50, and a medicine adding hole 52 is provided at the bottom of the medicine adding tank 50. The medicine adding hole 52 is communicated with the medicine adding cavity 51. A moving block 53 is slidably connected between the two mounting blocks 16. A communicating hole 54 is provided on the moving block 53. A medicine adding pipe 55 is fixedly connected to the bottom of the moving block 53 corresponding to the position of the communicating hole 54. The medicine adding pipe 55 is communicated with the medicine adding hole 52 through the communicating hole 54. A medicine adding cover 56 is provided at the bottom of the medicine adding pipe 55. The lower end surface of the medicine adding cover 56 abuts against the upper end surface of the filter tank 10. A hinge 57 is fixedly connected to one side of the medicine adding pipe 55 and the medicine adding cover 56. The medicine adding pipe 55 and the medicine adding cover 56 are hinged through the hinge 57. A connecting block 58 is fixedly connected to the lower end surface of the moving block 53. A cylinder 59 is provided on one side of the connecting block 58 away from the medicine adding pipe 55. The cylinder 59 is fixedly connected to the upper end surface of the filter tank 10. The output end of the cylinder 59 is fixedly connected to the outer wall of one side of the connecting block 58. In the specific use process, when the moving block 53 is in the non-medicine adding position, the medicine adding pipe 55 receives the medicine in the medicine adding tank 50 quantitatively through the communicating hole 54 of the communicating hole 54. Since the medicine adding cover 56 abuts against the upper end surface of the filter tank 10, the medicine adding cover 56 is in the closed state. When the filter tank 10 needs to be added with medicine, the cylinder 59 drives the connecting block 58 to move the moving block 53. The movement of the moving block 53 drives the medicine adding pipe 55 to move. When the medicine adding pipe 55 moves to the medicine adding position, the medicine adding cover 56 no longer abuts against the upper end surface of the filter tank 10. The weight of the medicine causes the medicine adding cover 56 to open, so that the medicine enters the filter tank 10. After the medicine adding is completed, the cylinder 59 drives the connecting block 58 to move the moving block 53. The movement of the moving block 53 drives the medicine adding pipe 55 to move to the non-medicine adding position. During the movement, the medicine adding cover 56 abuts against the upper end surface of the filter tank 10 again. This abutting effect causes the medicine adding cover 56 to close automatically, thus preventing the outflow of the medicine during the non-medicine adding period.

[0034] As an implementation mode in this embodiment, as Figure 8 shown, limiting sliders 60 are respectively fixedly connected to the outer walls of the opposite sides of the moving block 53. Transverse limiting chutes 61 adapted to the sizes of the limiting sliders 60 are respectively provided on the opposite inner side walls of the two mounting blocks 16 corresponding to the positions of the limiting sliders 60. The moving block 53 is slidably connected to the mounting blocks 16 through the limiting sliders 60. In the specific use process, the cooperation between the limiting sliders 60 and the limiting chutes 61 ensures the stability of the moving block 53 during the sliding process. This design prevents the moving block 53 from shifting or shaking during the movement, and ensures the accuracy and reliability of the entire structure during the movement.

[0035] Working principle: the water inlet pipe 11 introduces the sewage to be treated into the filter tank 10, the sewage tank 13 receives the impurities and sediments generated during the filtration process, and discharges the waste through the sewage pipe 14. The sewage enters the fiber filter turntable 23 through the filter cloth 24 under the action of gravity and pressure. The filter cloth 24 intercepts impurities such as suspended matter and organic matter. The rotating shaft 32 is driven to rotate by the driving motor 31. When the rotating shaft 32 rotates, the second transmission wheel 33 rotates accordingly. The rotation of the second transmission wheel 33 drives the first transmission wheel 30 to rotate through the belt 34. The rotation of the first transmission wheel 30 drives the water outlet pipe 21 to rotate. The rotation of the water outlet pipe 21 promotes the uniform distribution of sewage on the filter cloth 24 and improves the filtration efficiency. The filtered clean water enters the water outlet pipe 21 through the water outlet hole 22 and flows out from the water outlet pipe 12. The fiber filter turntable 23 rotates continuously, and the filter cloth 24 and the fixed scraper 46 produce relative movement to scrape off the dirt and impurities on the filter cloth 24, and the water suction pump 45 generates negative pressure when it works, so that the dirt and impurities are sucked into the suction channel in the cleaning suction block 41, and the dirt and impurities enter the connecting water pipe 43 through the cleaning water pipe 42, and are discharged through the water suction pipe 44. When it is necessary to add medicine, the cylinder 59 starts to work, driving the connecting block 58 and the moving block 53 to move, so that the dosing pipe 55 moves from the non-dosing position to the dosing position. After the dosing pipe 55 reaches the dosing position, the dosing cover 56 no longer conflicts with the upper end surface of the filter tank 10. The medicine opens the dosing cover 56 under the action of its own weight and enters the filter tank 10. After the dosing is completed, the cylinder 59 works again, driving the moving block 53 and the dosing pipe 55 to move back to the non-dosing position, and the dosing cover 56 conflicts with the upper end surface of the filter tank 10 again and closes to prevent the medicine from flowing out during the non-dosing period.

[0036] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
