Description

Technical Field

[0001] The invention relates to the technical field of desalted water, in particular to a desalted water sediment filtering device. Background Art

[0002] Water used in many industrial processes will produce saline wastewater, such as papermaking, textiles, chemicals and other industries. In order to reduce the impact on the environment, the salt and sediment in these wastewaters need to be effectively removed to meet the discharge or reuse standards. Sometimes, sediments due to water source pollution or treatment processes appear in urban water supply systems. The use of filtration devices can ensure that the final water quality meets health and safety standards. The use of filtration devices helps to reduce water pollution, protect natural water bodies and ecosystems, and prevent sediments from affecting aquatic organisms. Generally, desalted water contains a large amount of impurities that are easy to precipitate. These impurities vary in particle size, so it is necessary to filter them before carrying out the corresponding treatment process. In this process, the filtered impurities will accumulate on the filter. If they are not removed in time, the filter will be blocked, affecting the subsequent filtration effect.

[0003] Existing sewage sediment filtering devices are generally equipped with coarse and fine filter screens for graded filtration to improve the filtering effect. Dust and impurities on the filter screen are generally scraped and absorbed by a self-cleaning structure, and then the impurities are discharged through a sewage pipe. When removing impurities, a unidirectional rotating scraper is set to scrape the impurities on the filter screen. However, this method does not remove impurities thoroughly enough, and some impurities are still stuck on the filter screen and are difficult to remove, which affects the impurity removal effect; in addition, the structure of the cleaning mechanism on the filter screen is relatively simple, and it is not possible to remove the filter impurities of the coarse and fine filter screens at the same time, resulting in low cleaning efficiency.

[0032] The working principle of the present invention is as follows: the sewage is filtered and impurities are removed by a coarse filter 4 and a fine filter 5, and impurities are accumulated on the outer wall of the coarse filter 4 and the inner wall of the fine filter 5. The control of the pollution removal power mechanism 6 can drive the reciprocating rotary cleaning mechanism 7 to move up and down while rotating, and the dust on the inner wall of the fine filter 5 is removed and discharged to the outside of the filter tank 1 through the drain valve 8, and then the larger particle impurities attached to the outer wall of the coarse filter 4 can be scraped off by the lifting and circulating scraping mechanism 9 and fall into the sewage storage tank at the bottom of the filter tank 1, and then the drain pipe 10 is opened to remove the accumulated larger particle impurities to the outside of the filter tank 1.

[0033] Combined with Figure 2 , Attachment Figure 3 As shown, the dirt removal power mechanism 6 includes a protective cylinder 61 fixed on the top of the filter tank 1, a steering motor 62 is fixed on the top of the protective cylinder 61, the output shaft of the steering motor 62 is transmission-connected with a rotating shaft 63 rotatably arranged in the protective cylinder 61, the lower half of the rotating shaft 63 is provided with a thread, an internal threaded rotating seat 64 threadedly connected to the rotating shaft 63 is fixed on the protective cylinder 61, a rotating rod 65 is provided after the bottom end of the rotating shaft 63 passes through the top cover of the filter tank 1, and the rotating rod 65 is connected to the reciprocating rotating cleaning mechanism 7 and drives the reciprocating rotating cleaning mechanism 7 to rotate.

Since the rotating shaft 63 is threadedly connected with the internal thread rotating seat 64, and the internal thread rotating seat 64 is fixed on the protective tube 61, the rotating shaft 63 can move back and forth on the internal thread rotating seat 64, thereby driving the reciprocating rotary cleaning mechanism 7 to move up and down and rotate at the same time through the rotating rod 65.

[0035] Combined with Figure 3 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 and attached Fig.16 As shown, the reciprocating rotary cleaning mechanism 7 includes a limit rod 71 installed and fixed on the top cover of the filter tank 1, a limit block 7101 is provided at the bottom end of the limit rod 71, a slide groove 722 slidably connected to the limit rod 71 is provided on the protection box 72, a snap ring 651 is provided at the bottom of the rotating rod 65, and a snap groove 721 slidably connected to the snap ring 651 is provided on the protection box 72. After the rotating rod 65 passes through the protection box 72, a transmission gear 73 is sleeved and fixed. A mounting plate 74 is fixed in the protection box 72. The left and right sides of the mounting plate 74 are rotatably provided with a shift rod 75. The mounting plate 74 is provided with a steering control gear set 76 that meshes with the transmission gear 73 and can drive the shift rods 75 on both sides to rotate in the opposite direction. The steering control gear set 76 includes a matching gear 761 sleeved and fixed on the top of the shift rod 75 on one side and meshed with the transmission gear 73. The lower side of the matching gear 761 is sleeved and fixed A gear 1 762 is fixed on the lever 75, and a gear 2 763 is sleeved and fixed on the lever 75 on the other side. A pair of control gears 764 rotatably arranged on the top surface of the mounting plate 74 is provided between the gear 1 762 and the gear 2 763, and the gear 1 762, the two control gears 764, and the gear 2 763 are meshed with each other in sequence. After the lever 75 passes through the mounting plate 74, a rocker shaft 77 and a fan-shaped piece 78 are arranged in sequence from top to bottom. The rocker shaft 77 and the fan-shaped piece 78 are staggered and vertically distributed with each other. A rotating rod 2 79 is rotatably provided on the bottom surface of the mounting plate 74. A rotating key 710 is sleeved and fixed on the rotating rod 2 79. The rotating key 710 is respectively provided with a straight groove 711 and a fan-shaped groove 712 which are slidably connected with the rocker shaft 77 and the fan-shaped piece 78. A cleaning wheel 713 is fixed to the bottom end of the rotating rod 2 79, and the outer side of the cleaning wheel 713 is slidably connected to the inner wall of the fine filter 5. The straight grooves 711 are provided with two and are symmetrically distributed on the rotating key 710, a sliding block is provided on the rocker shaft 77 and is slidably connected to the straight groove 711, the fan-shaped grooves 712 are mirror-distributed on the left and right sides of the straight groove 711, and the cleaning wheel 713 is composed of four scrapers evenly distributed in a circle, and the outer side of the scraper is slidably connected to the inner wall of the fine filter 5.

[0036] The working principle of the reciprocating rotary cleaning mechanism 7 for scraping off impurities on the inner wall of the fine filter 5 is as follows: when the rotating rod 1 65 rotates, it drives the transmission gear 73 to rotate, and the transmission gear 73 drives the mating gear 761 meshing therewith to rotate. Since the mating gear 761 is sleeved and fixed on the lever 75, and the lower side of the mating gear 761 is provided with a gear 1 762 sleeved and fixed on the lever 75, the gear 1 762 rotates accordingly, and drives the gear 2 763 to rotate in the opposite direction through the two control gears 764, so that the gears on both sides can be controlled. The lever 75 of the lever 75 rotates in the opposite direction; the rocker shaft 77 and the fan-shaped piece 78 on the lever 75 cooperate with the straight groove 711 and the fan-shaped groove 712 on the rotating key 710 in sequence, and the rotating key 710 rotates back and forth 90 degrees, thereby driving the rotating rod 2 79 to do the same movement, and finally driving the cleaning wheel 713 to rotate back and forth 90 degrees. Since the cleaning wheel 713 is evenly distributed on the circumference of four scrapers, each scraper rotates 90 degrees, and the four scrapers can fully cover and scrape away the impurities on the inner wall of the fine filter 5 at 360 degrees. In addition, the rotating rod 1 65 moves up and down to drive the cleaning wheel 713 to move up and down in the fine filter 5, thereby scraping all the impurities on the inner wall of the fine filter 5, without dead angles, and with high efficiency.

[0037] Combined with Fig. 9 , Attachment Fig.10 , Fig.11 , Attachment Fig.12 and attached Fig.13 As shown, the lifting and lowering circulation scraping mechanism 9 includes a mounting ring 91 installed and fixed on the inner wall of the bottom of the filter tank 1, four fixing plates 92 evenly distributed around its circumference are fixed on the mounting ring 91, a bevel gear plate 93 is rotatably provided on the top surface, and a rotating shaft 94 is rotatably provided on the fixing plates 92. A motor 95 is installed and fixed on the outer wall of the bottom of the filter tank 1, and the output shaft of the motor 95 passes through the filter tank 1 and is fixedly connected to one of the rotating shafts 94. A bevel gear 96 which is sleeved and fixed on the rotating shaft 94 and meshed with the bevel gear plate 93 is provided on the inner side of the fixing plate 92, a crank rod 1 97 is fixed on the other end of the rotating shaft 94, and the other end of the crank rod 1 97 is rotatably connected to the crank rod 2 98, a scraping ring 99 is slidably connected to the outer wall of the coarse filter screen 4, and the outer wall of the scraping ring 99 is provided with a connecting block 910 rotatably connected to the other end of the crank rod 2 98.

[0038] The working principle of the lifting and lowering cycle scraping mechanism 9 to scrape off the impurities attached to the outer wall of the coarse filter 4 is as follows: the driving motor 95 works, and the output shaft of the motor 95 drives the second rotating shaft 94 to rotate, thereby driving the bevel gear 96 sleeved and fixed on the second rotating shaft 94 to rotate, and since the mounting ring 91 is provided with a bevel gear plate 93 meshing with the bevel gear 96, the bevel gear plate 93 rotates on the mounting ring 91, thereby driving the other bevel gears 96 meshing with the bevel gear plate 93 to rotate, thereby realizing that all the second rotating shafts 94 arranged on the fixed plate 92 are rotated. The two shafts 94 can rotate synchronously in the same direction. The rotation of the rotating shaft 94 will also drive the crank rod 1 97 to rotate, thereby rotating the crank rod 2 98 rotatably connected to the crank rod 1 97. Since the outer wall of the scraper ring 99 is provided with a connecting block 910 rotatably connected to the other end of the crank rod 2 98, the rotation of the rotating shaft 94 will drive the scraper ring 99 to circulate up and down along the outer wall of the coarse filter screen 4, scraping off the impurities attached to the outer wall of the coarse filter screen 4, and then accumulating them in the sewage storage tank at the bottom of the filter tank 1. The sewage discharge pipe 10 can be opened to discharge the impurities outside the filter tank 1.

[0039] Combined with Fig.14 , Attachment Fig.15 As shown, the drain valve 8 includes a flushing pipe 81 arranged between the top cover of the filter tank 1 and the fine filter 5, a connecting rod 82 is rotatably provided in the flushing pipe 81, and a baffle 83 is provided on the connecting rod 82 and is slidably connected to the inner wall of the flushing pipe 81. A supporting seat 84 is provided after the top of the connecting rod 82 passes through the flushing pipe 81, and a stepping motor 85 is fixedly installed on the supporting seat 84, and the output shaft of the stepping motor 85 is fixedly connected to the connecting rod 82.

[0040] The working principle of discharging impurities in the fine filter 5 out of the filter tank 1 by controlling the drain valve 8 is as follows: when the impurities on the inner wall of the fine filter 5 accumulate to a certain extent, the pressure in the fine filter 5 is greater than the pressure in the tank. At this time, when the impurities scraped off the fine filter 5 need to be discharged, the stepper motor 85 is driven to work, and the output shaft of the stepper motor 85 drives the connecting rod 82 to rotate, thereby driving the baffle 83 to rotate, so that the channel in the flushing pipe 81 is opened and connected. At this time, since the pressure in the fine filter 5 is greater than the pressure in the tank, the impurities removed from the fine filter 5 will be quickly discharged from the flushing pipe 81 until the pressure in the fine filter 5 reaches equilibrium with the outside world, and the sewage discharge process stops and the sewage discharge is completed.

[0041] In the specific implementation of the present invention, when it is necessary to filter and remove the easily precipitated matter in the desalted water, the desalted water is transported to the filter tank 1 through the water inlet pipe 2, and then filtered by the coarse filter 4 and then transported upward to the fine filter 5, and then filtered by the fine filter 5 and then transported to the filter tank 1, and then discharged through the water outlet pipe 3. The discharged water is the filtered water. At this time, a large amount of impurities remain on the outer wall of the coarse filter 4 and the inner wall of the fine filter 5, which need to be removed. The steering motor 62 is driven to work, driving the rotating rod 65 to rotate while moving up and down, driving the dust cleaning wheel 713 to rotate back and forth 90 degrees and move up and down, and remove the impurities on the inner wall of the fine filter 5. At the same time, the stepping motor 85 is driven to work, so that the inside of the sewage flushing pipe 81 is kept unobstructed. At this time, since the pressure in the fine filter 5 is greater than the pressure in the filter tank 1, the impurities removed in the fine filter 5 will be quickly discharged from the sewage flushing pipe 81 until the pressure in the fine filter 5 reaches equilibrium with the outside world, and the sewage discharge process automatically stops and the sewage discharge is completed. When it is necessary to remove larger particles of impurities attached to the outer wall of the coarse filter 4, the drive motor 95 works to drive the scraper ring 99 to move up and down along the outer wall of the coarse filter 4, scraping off the impurities attached to the outer wall of the coarse filter 4, and then accumulating them in the sewage storage tank at the bottom of the filter tank 1. The sewage pipe 10 is opened to discharge the impurities outside the filter tank 1.

[0042] It is worth mentioning that the steering motor 62, the stepper motor 85, and the motor 95 in the present invention are all existing devices well known to those skilled in the art, and their circuit connection methods and use control methods are all existing technologies.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and do not deviate from the purpose of the invention, they can creatively design a structure and embodiment similar to the technical solution, which should fall within the protection scope of the present invention.
