Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a water treatment multi-media filter. Background Art

[0002] According to the patent document with the announcement number CN221206944U, the backwashing operation is realized by adjusting the motor to drive the box body to be inverted and allowing water to flow into the box body through the outlet valve. When the water flow fills the inside of the box body, the drain valve is opened to discharge the sewage, and then the primary filter particles, intermediate filter particles and high-level filter particles in the box body are backwashed and cleaned. After the box body is turned over, the vibration generated by the driving motor is transmitted to the inside of the box body, thereby vibrating the primary filter particles, intermediate filter particles and high-level filter particles, so that the dirt therein is separated.

[0003] In the above patent documents, most of the multi-media filters are fixedly connected to them through hard pipes. Therefore, if the above-mentioned inverted cleaning method is adopted, the pipes connected thereto need to be disassembled, which is relatively cumbersome. Moreover, after inversion, the placement box is only immersed in water. At the same time, even if the dirt is cleaned out of the filter particles by the force generated by the vibration, the dirt needs to leak out from the perforations of the upper cover. At the same time, for the dirt mixed in the middle position of the filter particles, the dirt is still in the middle position of the filter particles by relying on the inversion method. During this process, some dirt may remain in the placement box, so the dirt cannot be completely cleaned. Utility Model Content

[0033] In this embodiment, the filter mechanism 1 includes a filter cartridge 11, a cover plate 15 is fixed on the top of the filter cartridge 11, and multiple sewage pipes 12 are installed on the side of the filter cartridge 11. A sliding plate frame 13 is provided on the sewage pipe 12 for controlling the outflow of sewage. The sliding plate frame 13 is provided with multiple openings corresponding to the sewage pipes 12. A first hydraulic cylinder 14 is installed on the upper end of the sliding plate frame 13 to drive it to move up and down. A plurality of sewage pipes 12 are provided near the outer side of the filter cartridge 11 with a slot for the sliding plate frame 13 to slide up and down. The filter cartridge 11 is located on the upper side of the sewage pipe 12. A water inlet pipe 17 is installed, and a water outlet valve 16 for controlling the outflow of filtered water is installed at the bottom of the filter cartridge 11. Water is supplied to the filter cartridge 11 through the water inlet pipe 17, and the water is filtered through the various filter media inside the filter cartridge 11. The filtered water is then sent out through the bottom of the water outlet valve 16. At the same time, when the filter media inside the filter cartridge 11 is cleaned, the sliding plate frame 13 is pushed along the slot by the telescopic part of the first hydraulic cylinder 14, so that the opening on the sliding plate frame 13 corresponds to the sewage pipe 12, thereby facilitating the discharge of sewage and dirt after cleaning.

[0034] In this embodiment: the lifting mechanism 4 includes a first partition 42, a ring frame is fixed on the top of the first partition 42, and a second hydraulic cylinder 41 is provided on the ring frame for driving it to move up and down. Two vertically distributed second partitions 43 are provided on the lower side of the first partition 42, and a third partition 44 is provided on the lower side of the two second partitions 43. The bottoms of the first partition 42 and the two second partitions 43 are fixed with a limiting frame 46, and the tops of the two second partitions 43 and the third partition 44 are fixed with an L-shaped seat 45 for sliding on the limiting frame 46. A plurality of sealing sleeves 33 are respectively rotatably connected to the center positions of the first partition 42, the two second partitions 43 and the third partition 44. The second hydraulic cylinder 4 The fixing portion is fixed to the top of the cover plate 15, and a bracket is fixed to the top of the cover plate 15. The telescopic portion of the second hydraulic cylinder 41 is shortened to drive the first partition 42 upward through the annular frame, and the limiting frame 46 at the bottom of the first partition 42 is driven to move upward synchronously. Then, the upper end of the L-shaped seat 45 on the second partition 43 slides on the limiting frame 46 of the first partition 42. When the upper end of the L-shaped seat 45 on the second partition 43 is buckled on the lower end of the limiting frame 46 at the bottom of the first partition 42, the two second partitions 43 begin to move away from each other. Similarly, the second partition 43 and the third partition 44 at its lower end can be pulled away from it, thereby increasing the distance between adjacent filter media during cleaning.

[0035] The cam 33 is provided with a plurality of grooves for connecting with the inner part of the rotating rod 31, and the cam 33 is provided with a plurality of stirring racks 32 and a sealing sleeve 33 on the outer side of the rotating rod 31. The sealing sleeve 33 is located at the lower side of the stirring rack 32. The center positions of the stirring rack 32 and the sealing sleeve 33 are provided with sliding holes for facilitating sliding up and down on the rotating rod 31. The rotating rod 31 is used to drive the plurality of stirring racks 32 and the sealing sleeve 33 on the outer side to rotate. The first partition plate 42, the two second partition plates 43 and the third partition plate 44 are moved away from each other so that the plurality of stirring racks 32 are located at the bottom of the two second partition plates 43 and the third partition plate 44. The cleaning water is flushed into the filter medium through the grooves on the rotating rod 31, and the filter medium is stirred and cleaned by the stirring rack 32, and the cleaned sewage and dirt are sent out from the sewage pipe 12.

[0036] In this embodiment: the rotating mechanism 5 includes a worm 52, and a worm wheel 53 is provided on one side of the worm 52 for fixing to the upper end of the rotating rod 31. A driving motor 51 is fixedly provided at the input end of the worm 52, and the rotating part of the driving motor 51 is used to drive the worm 52 to rotate, and the rotation of the worm 52 drives the worm wheel 53 and the rotating rod 31 to rotate.

[0037] In this embodiment: the water supply mechanism 2 includes a T-tube 21, a rotating connecting seat 24 is installed at one end of the T-tube 21, the rotating connecting seat 24 is installed at the upper end of the rotating rod 31, and the lower end of the T-tube 21 is connected to the water inlet pipe 17. A water inlet solenoid valve 22 for controlling water inlet during filtration is provided between the water inlet pipe 17 and the T-tube 21, and a cleaning solenoid valve 23 for controlling water inlet during cleaning is provided between the rotating rod 31 and the T-tube 21. The water inlet solenoid valve 22 is used to control the T-tube 21 to introduce water into the water inlet pipe 17, and the cleaning solenoid valve 23 is used to control the water introduction into the inside of the rotating rod 31.

[0038] Working principle: When filtering water, the cleaning solenoid valve 23 is closed and the water inlet solenoid valve 22 is opened. Then, water enters the water inlet pipe 17 through the T-tube 21, and then the water is introduced into the filter cartridge 11 by the water inlet pipe 17. The water is then filtered through the filter medium between the first partition 42, the two second partitions 43 and the third partition 44. The filtered water is then discharged through the bottom of the filter cartridge 11, and the entire water filtration process is completed.

[0039] When the filter needs to be cleaned, the water outlet valve 16 and the water inlet solenoid valve 22 are closed, and the cleaning solenoid valve 23 is opened. At the same time, the telescopic part of the first hydraulic cylinder 14 pushes the sliding plate frame 13 to move upward along the groove of the sewage pipe 12, and then the opening on the sliding plate frame 13 is made to correspond to the sewage pipe 12, and then the sewage pipe 12 is in an open state; at the same time, the telescopic part of the second hydraulic cylinder 41 drives the first partition 42 and the limiting frame 46 at its bottom to move upward synchronously through the annular frame, and then the upper end of the L-shaped seat 45 on the second partition 43 slides on the limiting frame 46 of the first partition 42. At this time, the first partition 42 and the second partition 43 begin to move away from each other. When the upper end of the L-shaped seat 45 on the second partition 43 is buckled on the lower end of the limiting frame 46 at the bottom of the first partition 42, the two second partitions 43 begin to move away from each other in the same way as described above. When the L-shaped seats 45 and the limiting frames 46 on the two second partitions 43 are interlocked with each other, the second partitions 43 and the third partitions 44 begin to move away from each other, and then the distance between adjacent filter media is expanded during cleaning; during the entire process of the first partition 42, the two second partitions 43 and the third partition 44 moving away from each other, the multiple stirring racks 32 and the sealing sleeve 33 move upward with them, and at this time, the rotating part of the driving motor 51 drives the worm gear 53 and the rotating rod 31 to rotate through the worm 52, and the rotation of the rotating rod 31 drives the multiple stirring racks 32 to rotate in the filter medium, and then stirs the dirt in the filter medium to separate the two. At the same time, the T-tube 21 sprays water to the filter medium through the strip groove of the rotating rod 31, and then flushes the dirt in the filter medium, and the flushed water is discharged through the sewage pipe 12 of the filter cartridge 11;

[0040] In addition, during the entire cleaning process, the height to which the filter medium splashes during flushing is lower than the corresponding height of the sewage pipe 12, thereby preventing the filter medium from flowing out of the sewage pipe 12 during the cleaning process.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
