DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Example 1

[0034] Reference Figure 1-2 A multi-stage channel filter element water purification device is designed, including a primary filter chamber 101, a secondary filter chamber 102 and a tertiary filter chamber 103. The primary filter chamber 101, the secondary filter chamber 102 and the tertiary filter chamber 103 are connected in series. A filter screen 1 is provided in the primary filter chamber 101, a filter cotton 104 is provided in the secondary filter chamber 102, and activated carbon particles 105 are provided in the tertiary filter chamber 103.

[0035] During water treatment, water flows into the primary filter chamber 101, filters out large particles of impurities through the filter screen 1, and then enters the secondary filter chamber 102. After the flocs in the water are filtered out by the filter cotton 104, the water flows into the tertiary filter chamber 103. The activated carbon particles 105 adsorb the odor and pigment in the water and then output it.

[0036] like Figure 5-13 A water inlet chamber 2 is fixedly connected to the filter screen 1, a reciprocating screw 8 and a spline shaft 9 are rotatably mounted on the water inlet chamber 2, a partition 6 is fixedly connected in the water inlet chamber 2, a short shaft 3 is rotatably mounted on the partition 6, an impeller 4 is fixedly connected to one end of the short shaft 3, and a large gear 5 is fixedly connected to the other end, two small gears 7 are rotatably mounted in the water inlet chamber 2, the small gears 7 are matched with the large gear 5, one of the small gears 7 is fixedly connected to the reciprocating screw 8, and the other small gear 7 is fixedly connected to the spline shaft 9, and a water inlet hole 201 is opened in the water inlet chamber 2 to accommodate water flow into the water inlet chamber 2.

[0037] When the filter 1 filters large particles of impurities, water flows into the water inlet chamber 2 through the water inlet hole 201 and tangentially impacts the impeller 4. The impeller 4 rotates under the impact of the water flow. The rotation of the impeller 4 drives the short shaft 3 to rotate. The rotation of the short shaft 3 drives the large gear 5 to rotate. The rotation of the large gear 5 drives the two small gears 7 to rotate. During the rotation of the small gear 7, the reciprocating screw 8 and the spline shaft 9 are driven to rotate.

[0038] like Figure 9-13As shown, a circular ring 10 is slidably engaged with the outside of the filter 1, and the ring 10 is threadedly engaged with the reciprocating screw 8. A first gear 11 is slidably engaged with the spline shaft 9, and the first gear 11 is rotatably mounted on the ring 10. A ring gear 12 is rotatably mounted on the ring 10, and a plurality of second gears 13 are rotatably mounted on the ring 10, and the second gears 13 cooperate with the ring gear 12. A plurality of pipe fittings 14 are fixedly connected to the ring 10, and a feeding screw 15 is rotatably mounted in the pipe fitting 14. The feeding screw 15 is coaxially fixed to the second gear 13, and a nozzle 16 is provided on the pipe fitting 14.

[0039] The reciprocating screw 8 drives the ring 10 to perform linear reciprocating motion along the axial direction of the filter screen 1 during the rotation process.

[0040] The spline shaft 9 rotates to drive the first gear 11 to rotate, the first gear 11 rotates to drive the ring gear 12 to rotate, the ring gear 12 rotates to drive the second gear 13 to rotate, and the second gear 13 rotates to drive the feeding screw 15 to rotate.

[0041] During the water treatment process, the amount of water in the primary filter chamber 101 is sufficient. When the feeding screw 15 rotates, the water in the primary filter chamber 101 will be drawn into the pipe 14 and sprayed out from the nozzle 16. Since the direction of the water flow sprayed from the nozzle 16 is perpendicular to the axis of the filter 1, the water flow sprayed from the nozzle 16 will impact the mesh of the filter 1 from the outside, thereby cleaning the impurities and particulate matter accumulated and blocked in the mesh of the filter 1 to the inside of the filter 1, so as to prevent the filter 1 from being blocked and further prevent the mesh area from being reduced.

[0042] Example 2

[0043] like Figure 3-9 As shown, a shell 18 is fixedly connected to the bottom of the filter screen 1, a sedimentation chamber 24 is fixedly connected to the shell 18, a first spring 26 is fixedly connected to the sedimentation chamber 24, an upper cover 25 is fixedly connected to the first spring 26, and the upper cover 25 is conical.

[0044] The elastic force of the first spring 26 is greater than the gravity of the upper cover 25. The upper cover 25 is in a normally open state under the elastic force of the first spring 26.

[0045] After the water treatment is completed, the water in the primary filter chamber 101 stops inputting and outputting. At this time, under the action of gravity, the impurity particles cleaned out from the mesh inside the filter 1 are precipitated, and some impurity particles fall directly into the sedimentation chamber 24, and some impurity particles fall on the upper cover 25. Since the upper cover 25 is a cone with a small top and a large bottom, the impurity particles falling on the upper cover 25 will fall into the sedimentation chamber 24 along the upper cover 25 under the action of gravity, so as to complete the collection of the impurity particles inside the filter 1.

[0046] Example 3

[0047] Since the upper cover 25 is in a normally open state, during the water treatment process, the water flow inside the filter 1 may bring the foreign particles in the sedimentation chamber 24 out of the sedimentation chamber 24. Therefore, to solve this problem, this embodiment is optimized based on the above-mentioned embodiment 2.

[0048] like Figure 13-16 As shown, a slide bar 27 is slidably mounted in the sedimentation chamber 24, one end of the slide bar 27 is fixedly connected to the upper cover 25, and the other end is fixedly connected to a magnetic member 28, a bearing seat 22 is fixedly connected in the outer shell 18, a rotating shaft 21 is rotatably mounted on the bearing seat 22, a driven gear 20 is fixedly connected to the rotating shaft 21, an extension shaft 17 is coaxially fixedly connected to the reciprocating screw 8, an end gear 19 is fixedly connected to the extension shaft 17, and the end gear 19 cooperates with the driven gear 20, a turntable 23 is fixedly connected to the rotating shaft 21, a permanent magnet 29 is slidably mounted on the turntable 23, a second spring 30 is fixedly connected to the turntable 23, the second spring 30 is connected to the permanent magnet 29, and a repulsive magnetic force is generated between the permanent magnet 29 and the magnetic member 28.

[0049] Based on the description in the above-mentioned embodiment 1, it can be known that the reciprocating screw 8 is always in a rotating state during the water treatment process. Therefore, the extension shaft 17 fixed to the reciprocating screw 8 will also rotate accordingly. The rotation of the extension shaft 17 will drive the end gear 19 to rotate. The rotation of the end gear 19 drives the driven gear 20 to rotate. The rotation of the driven gear 20 drives the rotating shaft 21 to rotate. The rotation of the rotating shaft 21 will drive the turntable 23 to rotate.

[0050] In a stationary state, the second spring 30 and the permanent magnet 29 are in a balanced state, and during the rotation of the turntable 23, the permanent magnet 29 will also rotate accordingly. During the rotation of the permanent magnet 29, it is acted upon by the centrifugal force and performs centrifugal motion. Under the action of the centrifuge, the permanent magnet 29 moves away from the axis of the turntable 23 and approaches the magnetic member 28.

[0051] Since the permanent magnet 29 and the magnetic member 28 generate a repulsive magnetic force, when the distance between the permanent magnet 29 and the magnetic member 28 decreases, the repulsive force between the two increases, and the magnetic member 28 moves downward under the action of the repulsive force.

[0052] The downward movement of the magnetic member 28 will drive the upper cover 25 to move downward through the slide rod 27, and the upper cover 25 will compress the first spring 26 and close the sedimentation chamber 24, thereby preventing the water flow from carrying out the impurity particles in the sedimentation chamber 24 during the water treatment process.

[0053] Working principle and workflow:

[0054] During water treatment, water flows into the primary filter chamber 101, filters out large particles of impurities through the filter screen 1, and then enters the secondary filter chamber 102. After the flocs in the water are filtered out by the filter cotton 104, the water flows into the tertiary filter chamber 103. The activated carbon particles 105 adsorb the odor and pigment in the water and then output it.

[0055] The water flow input into the primary filter chamber 101 enters the water inlet chamber 2 through the water inlet hole 201 and tangentially impacts the impeller 4. The impeller 4 rotates due to the impact of the water flow. The rotation of the impeller 4 drives the short shaft 3 to rotate. The rotation of the short shaft 3 drives the large gear 5 to rotate. The rotation of the large gear 5 drives the two small gears 7 to rotate. During the rotation of the small gear 7, the reciprocating screw 8 and the spline shaft 9 are driven to rotate.

[0056] The spline shaft 9 rotates to drive the first gear 11 to rotate, the first gear 11 rotates to drive the ring gear 12 to rotate, the ring gear 12 rotates to drive the second gear 13 to rotate, and the second gear 13 rotates to drive the feeding screw 15 to rotate.

[0057] During the water treatment process, the amount of water in the primary filter chamber 101 is sufficient. When the feeding screw 15 rotates, the water in the primary filter chamber 101 will be drawn into the pipe 14 and sprayed out from the nozzle 16. Since the direction of the water flow sprayed from the nozzle 16 is perpendicular to the axis of the filter 1, the water flow sprayed from the nozzle 16 will impact the mesh of the filter 1 from the outside, thereby cleaning the impurities and particulate matter accumulated and blocked in the mesh of the filter 1 to the inside of the filter 1, so as to prevent the filter 1 from being blocked and further prevent the mesh area from being reduced.

[0058] The reciprocating screw 8 drives the ring 10 to perform linear reciprocating motion along the axial direction of the filter screen 1 during rotation, thereby driving the nozzle 16 to move back and forth along the axial direction of the filter screen 1 through the ring 10 to clean the filter screens 1 at different heights.

[0059] The reciprocating screw 8 drives the extension shaft 17 to rotate during rotation, and the rotation of the extension shaft 17 drives the end gear 19 to rotate. The rotation of the end gear 19 drives the driven gear 20 to rotate. The rotation of the driven gear 20 drives the rotating shaft 21 to rotate. The rotation of the rotating shaft 21 drives the turntable 23 to rotate.

[0060] In a stationary state, the second spring 30 and the permanent magnet 29 are in a balanced state, and during the rotation of the turntable 23, the permanent magnet 29 will also rotate accordingly. During the movement, the permanent magnet 29 is subjected to the centrifugal force and performs centrifugal motion. Under the action of centrifugal force, the permanent magnet 29 moves away from the axis of the turntable 23 and approaches the magnetic member 28.

[0061] Since the permanent magnet 29 and the magnetic member 28 generate a repulsive magnetic force, when the distance between the permanent magnet 29 and the magnetic member 28 decreases, the repulsive force between the two increases, and the magnetic member 28 moves downward under the action of the repulsive force.

[0062] The downward movement of the magnetic member 28 will drive the upper cover 25 to move downward through the slide rod 27, and the upper cover 25 will compress the first spring 26 and close the sedimentation chamber 24, thereby preventing the water flow from carrying out the impurity particles in the sedimentation chamber 24 during the water treatment process.

[0063] Compared with the prior art, the water purification device provided by the present invention applies water flow impact to the mesh of the filter 1 from the outside to the inside through the nozzle 16 when the filter 1 filters the impurity particles in the water flow, so as to clean out the impurity particles accumulated and blocked in the mesh. After the water production is completed, the impurity particles that come out are precipitated and collected under the action of gravity to prevent the impurity particles from accumulating inside the filter 1 and affecting the subsequent water treatment work.

[0064] 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.
