The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] Embodiment 1:

[0038] A fresh water treatment device that can be quickly disassembled and assembled, such as Figures 1 to 9 As shown, it includes a base 1, a filter box 7 is fixed to the top of the base 1 through a support, and an intermediate tube 25 is welded to one end of the filter box 7, and a joint 26 is fixed to one end of the intermediate tube 25, and a fixed pipe 32 is rotatably connected to one end of the joint 26, and a connecting rod 3 is welded to the circumferential outer wall of the fixed pipe 32, and a driving ring 27 is welded to the outer wall of the connecting rod 3, a guide rod 13 is slidably connected to the through hole opened in the circumferential outer wall of the driving ring 27, and a guide plate 24 is welded to one end of the guide rod 13, and a spring 14 is clamped between the outer wall of one side of the guide plate 24 and the circumferential outer wall of the driving ring 27, and a vertical plate 48 is welded to the top of the base 1, and The through hole opened on the surface of the upright plate 48 is movably connected with an elastic pipe fitting, and the elastic pipe fitting and the guide plate 24 are connected by a pull rope 6 and a guide member supporting the pull rope 6. A top plate 17 is welded on the top of the filter box 7, and a lifting plate 30 is slidably connected to the through hole opened on the surface of the top plate 17, and a sliding plate 29 is welded to the side wall of the lifting plate 30, and a filter element is slidably connected to the inner walls of the two sliding plates 29, and the filter element includes a ceramic filter element 19, a slider 21 and a conical nozzle 22, and the conical nozzle 22 is rotatably connected to the inner wall of the through hole opened on the surface of the slider 21, and a ceramic filter element 19 is threadedly fixed to one end of the conical nozzle 22;

[0039] When fresh water needs to be processed, the slider 21 is slidably connected to the inner walls of the two sliding plates 29, and the sliding plates 29 are used to position the slider 21. When the slider 21 moves to the bottom of the sliding plates 29, the conical nozzle 22 and the elastic pipe are in a facing position. When fresh water needs to be filtered, the driving ring 27 is driven to rotate, and the centrifugal force generated by the high-speed rotation of the driving ring 27 causes the spring 14 to produce elastic deformation, thereby causing the guide rod 13 to slide outward relative to the driving ring 27 for a certain distance. During this process, the pull rope 6 Pulled by the guide rod 13 and the guide plate 24, the pull rope 6 pulls the elastic tube along the upright plate 48 for a certain distance during the movement. The elastic tube can also rotate while moving horizontally along the upright plate 48. After the elastic tube moves horizontally, it is engaged with the tapered nozzle 22, so that the elastic tube and the tapered nozzle 22 are sealed. When the fresh water is introduced into the filter box 7, the ceramic filter element 19 is used to filter the impurities in the fresh water, and the filtered fresh water is discharged through the tapered nozzle 22 and the elastic tube, thereby realizing the filtering treatment of the fresh water.

[0040] Furthermore, the support member includes a vertical plate 9 and a support rod 12, the vertical plate 9 is fixed to the top outer wall of the base 1 by bolts, and the support rod 12 is welded to the outer wall of one side of the vertical plate 9, and the outer walls on both sides of the support rod 12 are fixedly connected to the inner walls on both sides of the filter box 7;

[0041] The filter box 7 can be supported and fixed by providing the vertical plate 9 and the support rod 12 , thereby ensuring the stability of the filter box 7 .

[0042] Further, a support plate 2 is welded to the outer wall of the top of the base 1, and a connecting pipe 20 is welded to the outer wall of one side of the support plate 2, and the connecting pipe 20 and the vertical plate 9 are fixedly connected, a water inlet pipe 8 is welded to the top of the connecting pipe 20, and one end of the connecting pipe 20 is rotatably connected to one end of the fixed pipe 32, a driving motor 10 is fixed to the outer wall of one side of the support plate 2 by bolts, and the output end of the driving motor 10 and the circumferential outer wall of the fixed pipe 32 are both fixed with pulleys by screws, and a synchronous belt is used for transmission between the two pulleys;

[0043] The driving motor 10 drives the fixed pipe 32 to rotate by utilizing the transmission effect of the pulley and the synchronous belt. During the synchronous rotation of the fixed pipe 32 and the driving ring 27, the elastic pipe is pulled by the centrifugal force, thereby clamping the elastic pipe and the tapered nozzle 22.

[0044] Further, the elastic pipe comprises a rotating plate 5, a movable plate 39 and a water outlet pipe 41, the water outlet pipe 41 is movably connected to the inner wall of the through hole opened on the surface of the upright plate 48, and the movable plate 39 is rotatably connected to the inner wall of the through hole opened on one side of the filter box 7, and the water outlet pipe 41 is movably connected to the inner wall of the through hole opened on the surface of the movable plate 39, the rotating plate 5 and the circumferential outer wall of the water outlet pipe 41 are fixedly connected, and the rotating plate 5 and the end of the pull rope 6 away from the guide plate 24 are fixedly connected, the outer wall of the water outlet pipe 41 is sleeved with a spring 23, and the two ends of the spring 23 are respectively clamped between the outer wall of one side of the rotating plate 5 and the outer wall of one side of the movable plate 39;

[0045] When the pull rope 6 is pulled by the guide rod 13 and the guide plate 24 under the action of centrifugal force, the rotating plate 5 drives the water outlet pipe 41 to move along the upright plate 48. When the water outlet pipe 41 moves laterally, it docks with the conical mouth 22. The end of the conical mouth 22 is a conical structure, so that the water outlet pipe 41 is stuck into the outer wall of the conical mouth 22 after moving. A rubber gasket is provided at the contact position between the water outlet pipe 41 and the conical mouth 22. The rubber gasket is used to ensure the sealing effect between the two while increasing the friction between the two.

[0046] Further, a rectangular plate 42 is welded to the outer wall of the top of the lifting plate 30, and a T-shaped rod 43 is slidably connected to the inner wall of the through hole opened on the surface of the rectangular plate 42, and a latching tooth 46 is fixed to one end of the T-shaped rod 43, and a spring 44 is sleeved on the outer wall of the circumference of the T-shaped rod 43, and the two ends of the spring 44 are respectively clamped on the inner wall of one side of the T-shaped rod 43 and the outer wall of one side of the rectangular plate 42, and a one-way tooth plate 45 used in conjunction with the latching tooth 46 is welded to the outer wall of the top of the top plate 17;

[0047] An L-shaped plate 34 is welded to the outer wall of one side of the filter box 7, and a hollow cylinder 36 is fixed to the inner wall at the bottom of the L-shaped plate 34 by screws, and a sliding rod 38 is slidably connected to the through hole opened at the top of the hollow cylinder 36, and a spring 37 is clamped between the bottom of the sliding rod 38 and the inner wall at the bottom of the hollow cylinder 36, and a blocking plate 28 is welded to the outer wall at the top of the sliding rod 38, and the top of the blocking plate 28 and the bottom of the lifting plate 30 are fixedly connected by bolts;

[0048] When it is necessary to limit the position of the filter element, after sliding the slider 21 and the two sliding plates 29 together, the lifting plate 30 is moved downward along the top of the top plate 17. During this process, the latch 46 slides along the surface of the one-way tooth plate 45. Since the latch 46 can only slide in one direction along the one-way tooth plate 45, the one-way tooth plate 45 can limit the latch 46. During the downward movement, the lifting plate 30 presses the sealing plate 28, so that the spring three 37 is in a compressed state. The one-way tooth plate 45 is used to limit the latch 46, so as to prevent the lifting plate 30 from being bounced up under the elastic force of the spring three 37, thereby ensuring the stability of the lifting plate 30, and then ensuring the stability between the filter element and the elastic tube after alignment.

[0049] Furthermore, a connecting hole 31 is provided at the bottom of the filter box 7, and a collecting box 33 is welded to the filter box 7, and a hose 35 is fixed to the bottom of the collecting box 33 by bolts, a strip hole 47 is provided on the surface of the blocking plate 28, and a valve 40 is connected to the outer wall of one side of the filter box 7 by threads;

[0050] When the fresh water needs to be filtered and the inside of the filter box 7 needs to be cleaned, the filter element is removed from the sliding plate 29 and the T-bar 43 is pulled along the rectangular plate 42. After the latching teeth 46 and the one-way tooth plate 45 are disengaged from each other, the lifting plate 30 is moved up and reset under the action of the rebound force of the spring three 37. During this process, the side wall of the lifting plate 30 blocks one end of the water outlet pipe 41 to prevent the waste liquid from being discharged through the water outlet pipe 41 during subsequent flushing. In the process of synchronous upward movement of the blocking plate 28, the strip hole 47 gradually moves to the connection between the filter box 7 and the collection box 33, so that the filter box 7 and the collection box 33 are connected. By connecting the valve 40 and the flushing pipe, the flushing liquid is introduced into the filter box 7 through the valve 40 to flush the inside of the filter box 7, thereby flushing the impurities attached to the inside of the filter box 7. After being flushed, the impurities are introduced into the collection box 33 through the strip hole 47 and finally discharged through the hose 35.

[0051] More preferably, a card plate 51 is welded to the inner wall of the top of the lifting plate 30, one end of the top plate 17 is connected to the cover plate 4 through a hinge, and a plug hole 11 matching the outer diameter of the card plate 51 is opened on the surface of the cover plate 4;

[0052] When the filter element is installed, the cover plate 4 is closed along the top plate 17, and the lifting plate 30 drives the card plate 51 to move downward and insert into the socket 11 during the downward movement. The card plate 51 and the socket 11 can be used to limit the position between the cover plate 4 and the top plate 17, thereby ensuring that the cover plate 4 does not shake relative to the top plate 17 during the filtering process of fresh water, thereby ensuring the stability between the two.

[0053] Furthermore, the guide member includes a sleeve 49 and a collar 50, the sleeve 49 is fixed to the outer wall of one side of the rotating plate 5 by screws, and the collar 50 and the sleeve 49 are slidably connected, a connecting plate 15 is welded to the outer wall of one side of the driving ring 27, and the connecting plate 15 and the collar 50 are fixedly connected, and a pulley 16 for guiding the pull rope 6 is rotatably connected to the bottom of the connecting plate 15;

[0054] The pulley 16 can be provided to guide the pull rope 6 during its movement, and the sleeve 49 and the ring 50 can be used to connect the rotating plate 5 and the connecting plate 15, thereby ensuring that the rotating plate 5 can rotate synchronously when the driving ring 27 rotates.

[0055] When the present embodiment is in use, the cover plate 4 is first opened along the top plate 17, and then the conical nozzle 22 is slid along the sliding plate 29 to the bottom of the lifting plate 30. Then, after the cover plate 4 is closed, the lifting plate 30 is moved down along the top plate 17. During the downward movement of the lifting plate 30, the latching teeth 46 slide unidirectionally along the one-way tooth plate 45. During this process, the blocking plate 28 compresses the spring 37 during the synchronous downward movement, and the strip hole 47 gradually moves to the bottom of the filter box 7. Then, the driving motor 10 is used to drive the driving ring 27 to rotate. During the rotation of the driving ring 27 The spring 14 is deformed under the action of centrifugal force, and the guide plate 24 causes the pull rope 6 to pull the rotating plate 5 during the movement. After being pulled, the rotating plate 5 drives the water outlet pipe 41 to move horizontally and insert into the outer wall of the conical nozzle 22, thereby realizing the clamping fixation between the water outlet pipe 41 and the conical nozzle 22. Then, the water inlet pipe 8 is used to introduce the fresh water to be filtered into the filter box 7, and the ceramic filter element 19 is used to filter the impurities in the fresh water. The filtered fresh water passes through the ceramic filter element 19 and enters the water outlet pipe 41, thereby realizing the filtration of the fresh water.

[0056] Embodiment 2:

[0057] A fresh water treatment device that can be quickly disassembled and assembled, such as Figure 4 As shown, in order to facilitate preliminary cleaning of the ceramic filter element 19, this embodiment makes the following supplements on the basis of embodiment 1: the inner walls on both sides of the filter box 7 are fixed with scrapers 18 by screws, and the surface of the scraper 18 is fixed with bristles by embedding;

[0058] When the water outlet pipe 41 and the conical nozzle 22 are clamped together, since a rubber gasket is provided between the water outlet pipe 41 and the conical nozzle 22, the water outlet pipe 41 can drive the ceramic filter element 19 and the conical nozzle 22 to rotate along the slider 21 by utilizing the friction between the rubber gasket and the conical nozzle 22 during rotation. During the rotation of the ceramic filter element 19, the bristles on the scraper 18 can scrape off the impurities filtered and trapped by the circumferential outer wall of the ceramic filter element 19, thereby preventing the accumulation of impurities on the ceramic filter element 19 and affecting the normal filtration of fresh water, thereby extending the period for replacing the ceramic filter element 19.

[0059] Embodiment 3:

[0060] A fresh water treatment device that can be quickly disassembled and assembled, such as Fig.10 As shown, in order to improve the cleaning effect of impurities, this embodiment makes the following improvements on the basis of embodiment 1: the sliding plate 29 is replaced by a fixed seat 53, and the fixed seat 53 is fixedly connected to the inner walls of both sides of the filter box 7, and the outer diameter of the slider 21 is adapted to the inner diameter of the fixed seat 53, and a recoil nozzle 52 is welded at one end of the conical nozzle 22, and a cleaning hole is opened on the circumferential outer wall of the recoil nozzle 52;

[0061] By fixing the fixing seat 53 and the filter box 7, when it is necessary to flush the impurities in the filter box 7, when the lifting plate 30 slides along the top plate 17, the position of the slider 21 remains unchanged. When the strip hole 47 moves to the connection between the filter box 7 and the collection box 33, the ceramic filter element 19 is removed from the conical nozzle 22 through the thread. When the filter box 7 is backwashed through the outlet pipe 41, the outlet pipe 41 is driven by the driving motor 10 to rotate, so that when the outlet pipe 41 drives the conical nozzle 22 and the backwashing nozzle 52 to rotate synchronously, water passes through The cleaning hole on the recoil nozzle 52 sprays water. Since the cleaning hole on the recoil nozzle 52 sprays water during the rotation process, the sprayed water can rinse various areas of the inner wall of the filter box 7, thereby avoiding the existence of cleaning dead corners and improving the cleaning effect. The cleaned waste liquid is introduced into the bottom of the collection box 33 through the strip hole 47, and finally discharged through the hose 35. In this way, when the ceramic filter element 19 and the conical nozzle 22 are fixed, the fresh water is filtered. When the ceramic filter element 19 is removed from the conical nozzle 22, the recoil nozzle 52 is used to backwash the water to rinse and clean the inner wall of the filter box 7.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
