Technical Field
[0001] The utility model relates to the technical field of sewage treatment, in particular to a highly efficient and environment-friendly sewage treatment device. Background Technique
[0002] A highly efficient and environment-friendly sewage treatment device (DTRO) is a patented membrane separation device using the technology of disk tube reverse osmosis membrane, which is specially used for treating high-concentration wastewater. The working principle of the DTRO device is that the feed liquid enters the channels formed by the flow guide disks through the gap between the membrane stack and the shell in the pressure vessel, quickly passes through the filter membrane, and forms a double "S" shaped route under the guidance of the flow guide disks. Finally, the concentrated liquid flows out from the feed end. This design makes the treatment liquid form a turbulent flow on the membrane surface, effectively reducing the fouling and scaling phenomena, prolonging the service life of the membrane sheets, and facilitating cleaning and maintenance at the same time.
[0003] The existing patent CN212356649U discloses a disk tube reverse osmosis device for landfill leachate. In the utility model, a first shock absorption device is installed between the mounting frame and the base, and the first spring is used to shock absorb the mounting frame and multiple disk tubes on the mounting frame, improving the stability of the disk tubes during use.
[0004] The above technical solution solves the problem that the disk tubes cannot operate stably by setting a shock absorption structure, installing a telescopic rod between the base and the mounting frame, and the telescopic rod cooperating with the first spring to buffer the vibration between the base and the mounting frame.
[0005] However, in actual use, there are still the following deficiencies. For example, a sewage pretreatment mechanism is not installed on the disk tube body. When the disk tube body treats sewage, the sewage may contain relatively large impurities, which may cause the impurities to block inside the disk tube body, resulting in damage to the disk tube body and being not conducive to improving the treatment efficiency of the sewage treatment device.

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0035] Such as Figure 1 - Figure 4As shown in the figure, this embodiment provides a technical solution: an efficient and environmentally friendly sewage treatment device, including a bracket 1, a disc tube reverse osmosis membrane column 2, a feed water pump 3, and a high-pressure pump 5. A disc tube reverse osmosis membrane column 2 is arranged on one side of the bracket 1, and a pretreatment component 4 is arranged on the side of the bracket 1 away from the disc tube reverse osmosis membrane column 2. A discharge component 6 is arranged inside the pretreatment component 4, and a sealing component 7 is arranged at one end of the pretreatment component 4 away from the discharge component 6. Both the feed water pump 3 and the high-pressure pump 5 are arranged on the side of the bracket 1 close to the pretreatment component 4;
[0036] As Figure 1 - Figure 4 As shown in the figure, the pretreatment component 4 includes a barrel body 41 and a threaded rod 48. The barrel body 41 is arranged on the side of the bracket 1 away from the disc tube reverse osmosis membrane column 2. A push plate 42 is arranged on the inner wall of the barrel body 41. A filter screen 43 is fixedly connected to one side of the barrel body 41 close to the push plate 42. A rotating base 44 is arranged on the filter screen 43. The rotating base 44 is fixedly connected to the push plate 42. A sleeve 47 is movably inserted into the rotating base 44. An electric telescopic rod 46 is arranged at one end of the barrel body 41 close to the sleeve 47. The output end of the electric telescopic rod 46 is fixedly connected to the sleeve 47. The threaded rod 48 is movably inserted into the sleeve 47. A fixing column 49 is fixedly connected to one end of the sleeve 47 close to the threaded rod 48. The fixing column 49 is slidably connected to the threaded rod 48. The top of the threaded rod 48 is fixedly connected to a top cover 45. The top cover 45 is slidably connected to the rotating base 44. By fixedly connecting the feed water pump 3 to the top of the barrel body 41 and starting the feed water pump 3 to convey sewage into the barrel body 41, the filter screen 43 filters large-volume impurities in the sewage, and the filtered sewage enters the inside of the drainage chamber 62 through the filter screen 43. Then start the high-pressure pump 5 to convey the sewage inside the drainage chamber 62 into the inside of the disc tube reverse osmosis membrane column 2, and use the disc tube reverse osmosis membrane column 2 to treat the sewage. Then start the electric telescopic rod 46, and the electric telescopic rod 46 drives the sleeve 47 to move downward. The sleeve 47 drives the threaded rod 48 and the top cover 45 to move downward through the fixing column 49, and the top cover 45 is clamped inside the rotating base 44, so that the rotating base 44 limits the top cover 45. At this time, the sleeve 47 continues to drive the fixing column 49 to move downward, so that the fixing column 49 drives the threaded rod 48 to rotate through the thread on the threaded rod 48, and the threaded rod 48 drives the rotating base 44 and the push plate 42 to rotate through the top cover 45, and pushes the impurities filtered by the filter screen 43 into the inside of the discharge chamber 63, thus solving the problem that large-volume impurities in the sewage are blocked inside the disc tube reverse osmosis membrane column 2, which is beneficial to improving the working efficiency of the sewage treatment device.
[0037] In order to prevent the sewage from mixing with the impurities and improve the filtration efficiency, as Figure 2As shown in the figure, the discharging assembly 6 includes a drainage chamber 62 and a discharging chamber 63. The drainage chamber 62 is opened at one end of the barrel body 41 close to the filter screen 43. The drainage chamber 62 is fixedly communicated with the disc tube reverse osmosis membrane column 2 through a high-pressure pump 5. The discharging chamber 63 is opened at one end of the barrel body 41 close to the push plate 42. A partition plate 61 is arranged between the drainage chamber 62 and the discharging chamber 63. The partition plate 61 is fixedly connected with the barrel body 41 and the electric telescopic rod 46. A storage box 64 is fixedly connected to one side of the barrel body 41 close to the discharging chamber 63. Through the cooperation of the pretreatment assembly 4 and the discharging assembly 6, the filter screen 43 filters impurities, enabling sewage to enter the inside of the partition plate 61. The partition plate 61 separates the drainage chamber 62 from the discharging chamber 63, allowing the sewage to be discharged from the inside of the drainage chamber 62. After the push plate 42 rotates to push the impurities into the inside of the discharging chamber 63, the impurities fall into the inside of the storage box 64. A slag discharge port is installed on the storage box 64, and the slag discharge port is connected to an external sewage pump, facilitating the rapid discharge of impurities.
[0038] To avoid the problem that when the push plate 42 rotates, water continuously enters the inside of the barrel body 41, causing sewage to flow into the discharging chamber 63, as Figure 2 shown, the sealing assembly 7 includes a sealing ring 71 and a sealing plate 72. The sealing ring 71 is fixedly connected to one end of the barrel body 41 close to the top cover 45. The sealing plate 72 is movably inserted on one side of the sealing ring 71. A connecting rod 73 is fixedly connected between the sealing plate 72 and the top cover 45. By starting the electric telescopic rod 46, when the electric telescopic rod 46 drives the top cover 45 to move downward, the top cover 45 drives the sealing plate 72 to move together through the connecting rod 73, causing the sealing plate 72 to be sealed inside the sealing ring 71, sealing the inside of the barrel body 41. However, when the top cover 45 moves upward, the connecting rod 73 pushes the sealing plate 72 to separate from the sealing ring 71, allowing sewage to flow into the inside of the barrel body 41. Thus, by adjusting the position of the top cover 45, the sealing state of the sealing ring 71 and the sealing plate 72 is controlled, realizing the integrated control of the sealing plate 72 and the top cover 45, accurately controlling the timing of sewage entry, avoiding unnecessary leakage and pollution, and contributing to ensuring the stability and safety of the production process.
[0039] Furthermore, as Figure 3 shown, a slider 8 is fixedly connected to one side of the filter screen 43 close to the rotating base 44. A chute 9 is opened on one side of the rotating base 44 close to the slider 8. The rotating base 44 is slidably connected to the filter screen 43 through the slider 8 and the chute 9. Through the cooperation of the slider 8 and the chute 9, it is convenient for the rotating base 44 to rotate on the filter screen 43 while also improving the stability of the rotating base 44 during rotation, which is beneficial to improving the stability of the sewage treatment device.
[0040] Furthermore, as Figure 3 - Figure 4As shown in the figure, a first limiting block 10 is fixedly connected to one side of the top cover 45 close to the rotating base 44, and a first limiting groove 11 is fixedly connected to one side of the rotating base 44 close to the first limiting block 10. The top cover 45 is clamped with the top cover 45 through the first limiting block 10 and the first limiting groove 11. By clamping the first limiting block 10 inside the first limiting groove 11, when the threaded rod 48 drives the top cover 45 to rotate, the top cover 45 pushes the rotating base 44 to rotate through the first limiting block 10 and the first limiting groove 11, so as to realize that the rotating base 44 drives the push plate 42 to rotate and push the impurities into the inside of the discharge chamber 63.
[0041] Furthermore, as Figure 4 shown in the figure, a second limiting block 12 is fixedly connected to one side of the sleeve 47 close to the rotating base 44, and a second limiting groove 13 is formed on one side of the rotating base 44 close to the second limiting block 12. The sleeve 47 is slidably connected to the rotating base 44 through the second limiting block 12 and the second limiting groove 13. By matching the second limiting block 12 with the second limiting groove 13, it is avoided that the sleeve 47 deviates when sliding inside the rotating base 44, and the situation that the fixed column 49 cannot drive the threaded rod 48 is avoided, which is beneficial to improving the stability of the sewage treatment device.
[0042] Working principle: As Figure 1 - Figure 4 shown in the figure:
[0043] When in use: First, start the water inlet pump 3 to make the water inlet pump 3 transport the external sewage to the inside of the barrel body 41. The sewage passes through the sealing ring 71 and the sealing plate 72, and the filter screen 43 filters the large-volume impurities in the sewage. The sewage flows into the inside of the drainage chamber 62. Then start the high-pressure pump 5 to transport the sewage in the drainage chamber 62 to the inside of the disc tube reverse osmosis membrane column 2, so that the disc tube reverse osmosis membrane column 2 treats the sewage. Then start the electric telescopic rod 46. The electric telescopic rod 46 drives the sleeve 47 to move downward. The sleeve 47 drives the threaded rod 48 and the top cover 45 to move downward through the fixed column 49, and clamps the top cover 45 inside the rotating base 44. At this time, the connecting rod 73 drives the sealing plate 72 to move along with the top cover 45, and the sealing plate 72 seals inside the sealing ring 71 to cut off the water flow. Then, the rotating base 44 limits the top cover 45. At this time, the sleeve 47 continues to drive the fixed column 49 to move downward, so that the fixed column 49 drives the threaded rod 48 to rotate through the thread on the threaded rod 48, and the threaded rod 48 drives the rotating base 44 and the push plate 42 to rotate through the cooperation of the top cover 45 and the first limiting block 10, and pushes the impurities filtered by the filter screen 43 into the inside of the discharge chamber 63. Then connect the storage box 64 with an external sewage pump to discharge the impurities inside the storage box 64.
[0044] The above are only the preferred embodiments of the present utility model and do not constitute other forms of limitation to the present utility model. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as they do not depart from the technical solution content of the present utility model, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
