Description

Technical Field

[0001] The invention relates to the technical field of water purification, and in particular to a multi-filter water purifier. Background Art

[0002] A water purifier is a device used to remove impurities and harmful substances from water. It aims to provide safer, pollution-free water and protect subsequent water-using appliances. Water purifiers usually purify water through multiple physical filtrations, chemical reactions or biological treatments. In order to be suitable for a variety of working environments such as homes, commercial places and industrial environments, the number of filter elements is usually increased and the type of filter elements is changed. Especially for industrial wastewater, the role of water purifiers is particularly important.

[0003] The filter element in the existing water purifier is usually stationary on the outer shell, and the filter element will continuously filter impurities in the water during the water purification process. Long-term use of the filter element will cause impurities to accumulate on it. Due to the high cost of the filter element, the filter element is usually processed by cleaning. When too many impurities accumulate on the filter element, if the filter element is not cleaned in time, the filter element will be blocked by impurities, thereby affecting the normal water purification work.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0045] like Figure 1-Figure 4As shown in the figure, it is an embodiment of the present invention, which proposes a multi-filter water purifier to solve the problem that the filter element in the existing water purifier is relatively fixed, resulting in impurities adhering to it being unable to automatically detach, affecting the normal operation of the water purification, including: a shell 1, the shell 1 is fixedly connected and connected with a pipe 2, a water outlet pipe 3 and an intermediate pipe 4, and the intermediate pipe 4 is connected with the pipe 2; a first ring 5 and a rotating shaft 601, both of which are rotatably connected to the shell 1; a first rotating plate 602, which is slidably and rotatably connected to the rotating shaft 601, and a first fixed ring 5 and a first rotating plate 602 are fixedly connected between the first ring 5 and the first rotating plate 602. A filter element 7, a second filter element 8 is fixedly connected in the shell body 1, the second filter element 8 is rotatably connected to the rotating shaft 601, and the second filter element 8 is located in the first filter element 7; an isolating member 9, rotatably connected in the shell body 1, the isolating member 9 is fixedly connected to the first filter element 7; a power mechanism, arranged between the shell body 1 and the pipe fitting 2, for causing the first rotating plate 602 and the rotating shaft 601 to move relative to each other, thereby causing the first filter element 7 to deform; a spacing mechanism, arranged between the first ring 5 and the first rotating plate 602, for causing the first ring 5 and the first rotating plate 602 to move at intervals.

[0046] In the above scheme, a mark is provided on the shell 1 to indicate the direction of water flow, which is convenient for correct installation. The pipe fitting 2 and the water outlet pipe 3 are respectively located at the lower side and the upper side of the shell 1. The pipe fitting 2 and the water outlet pipe 3 are both installed with joints to facilitate connection with the external waterway. The first filter element 7 is a membrane filter element, which is used to filter out fine suspended matter and heavy metal ions. The second filter element 8 is a post-filter element, which is made of activated carbon and is used to further filter some fine substances to ensure that the outlet water quality meets the standard. The first filter element 7 "wraps" the second filter element 8. The outer side of the isolation member 9 is a hard material, and the inner side is a "membrane" material, which is used to isolate the upper and lower sides thereof. When using this device, the pipe fitting 2 and the water outlet pipe 3 are first connected to the external waterway through the joints on each of them, and then the water in the external waterway enters from the pipe fitting 2. The water enters the middle pipe 4, and then enters the shell 1. The water passes through the first filter element 7 and the second filter element 8 and then enters the water outlet pipe 3. During the process, the water moves from bottom to top in the shell 1, and finally the water (clean water) enters the external waterway again. During the process, the power mechanism is used to rotate and move upward the first rotating plate 602, so that the first filter element 7 is deformed, thereby applying external force to the impurities accumulated on the bending area of ​​the first filter element 7, and promoting the impurities to fall off, so as to realize the self-cleaning of the first filter element 7, avoid the first filter element 7 during the long-term operation, the accumulated impurities cause blockage, thereby affecting the normal progress of the water purification work, and at the same time reduce the work intensity of the staff, and then the spacing mechanism is used to reset the first filter element 7. With the continuous work, the first filter element 7 is repeatedly deformed and reset.

[0047] like Figure 3-Figure 7As shown, the power mechanism includes: a rotating shaft 1001, which is rotatably connected to the pipe 2, the rotating shaft 1001 is fixedly connected with a first turbine 1002 and a worm 1003, the rotating shaft 601 is fixedly connected with a second turbine 1004 and a worm wheel 1005, the second turbine 1004 is located on the side of the rotating shaft 601 close to the water outlet pipe 3, and the worm wheel 1005 is meshed with the worm 1003; a first telescopic rod 1006, which is installed on the worm wheel 1005, the first rotating plate 602 limits the first telescopic rod 1006, and there is a certain relative sliding margin between the two, the first rotating plate 602 is fixedly connected with a circumferentially distributed first limiting member 1007, the first The telescopic rod 1006 and the adjacent first limiting member 1007 limit each other, the shell 1 is provided with a limiting groove 1008, the first rotating plate 602 is provided with a limiting protrusion, the limiting groove 1008 is used to limit the limiting protrusion of the first rotating plate 602, the limiting groove 1008 is composed of a first groove 10081, a second groove 10082 and a third groove 10083 connected end to end, the first groove 10081 is a horizontal groove, the second groove 10082 is a vertical groove, the third groove 10083 is a spatial arc groove, and the limiting grooves 1008 are distributed throughout the shell 1, so as to change the local area of ​​the first filter element 7 at the connection between the shell 1 and the intermediate tube 4.

[0048] In the above scheme, the first turbine 1002 and the worm 1003 are respectively located at the left and middle of the rotating shaft 1001, and the first turbine 1002 is located at the left side of the connection between the pipe 2 and the intermediate pipe 4 (such as Figure 4 The first limiting member 1007 is provided with an inclined surface (the cross section is a "right-angled trapezoid"), and the inclined surface on the first limiting member 1007 squeezes the inclined surface on the telescopic end of the first telescopic rod 1006. The first limiting member 1007 is made of elastic material, and there are two limiting protrusions on the first rotating plate 602 distributed in the circumferential direction. There are two first grooves 10081, two second grooves 10082 and two third grooves 10083 on the limiting groove 1008, and the two adjacent grooves are connected (together forming a "ring-shaped" closed groove), which is used to balance the force on the first rotating plate 602.

[0049] After the water enters the pipe 2, the flowing water impacts the first turbine 1002, and then the first turbine 1002 starts to rotate clockwise (such as Figure 4 Taking the left view as an example), the first turbine 1002 drives the rotating shaft 1001 to rotate clockwise, the rotating shaft 1001 drives the worm 1003 to rotate clockwise, and the worm 1003 drives the worm wheel 1005 to rotate counterclockwise (such as Figure 4The worm gear 1005 drives the rotating shaft 601 and the first telescopic rod 1006 to rotate counterclockwise together. When the first telescopic rod 1006 rotates counterclockwise until the vertical surface corresponding to the vertical waist on the telescopic end contacts the adjacent first limiting member 1007, the first telescopic rod 1006 drives the first rotating plate 602 to rotate counterclockwise together through the first limiting member 1007. At that time, the limiting protrusion on the first rotating plate 602 slides in the first groove 10081 (the initial state is now described as the limiting protrusion on the first rotating plate 602 is located in the first groove 10081). During the process, the first rotating plate 602 drives the first filter element 7 to rotate counterclockwise together through the spacing mechanism, thereby changing the area of ​​the first filter element 7 facing the connection between the shell 1 and the intermediate tube 4, thereby reducing the local area of ​​the first filter element 7 from being subjected to water (untreated water) impact for a long time, so that impurities in the water gather in the local area of ​​the first filter element 7, thereby affecting the normal water purification work.

[0050] During the counterclockwise rotation of the first rotating plate 602, when the limiting protrusion on the first rotating plate 602 enters the third groove 10083, the third groove 10083 limits the limiting protrusion on the first rotating plate 602, and the first rotating plate 602 begins to move upward under the limiting action of the third groove 10083 (the first rotating plate 602 stretches the first telescopic rod 1006), and the first rotating plate 602 drives the first filter element 7 to undergo axial deformation (wrinkles appear), thereby causing impurities adhering to the first filter element 7 to fall off, thereby improving the water purification efficiency of the first filter element 7 and reducing the work intensity of the staff. When the limiting protrusion on the first rotating plate 602 rotates counterclockwise to enter the adjacent second groove 10082, the first rotating plate 602 moves downward along the second groove 10082 under the action of the spacing mechanism, and finally the limiting protrusion on the first rotating plate 602 enters the adjacent first groove 10081.

[0051] like Figure 3-Figure 8 As shown, the spacing mechanism includes: a first elastic element 1101, fixed between the first ring 5 and the first rotating plate 602, the first elastic element 1101 partially penetrates the isolation member 9; a second ring 1102, rotatably connected to the first rotating plate 602, the second ring 1102 is fixed with a moving rod 1103, the moving rod 1103 is slidably connected with a first extrusion rod 1104, the first extrusion rod 1104 is slidably connected to the first ring 5, and a second elastic element 1105 is fixed between the first extrusion rod 1104 and the moving rod 1103.

[0052] In the above scheme, the first elastic element 1101 is a spring, which has the ability of compression and torsion energy storage. A ball is arranged on the first extrusion rod 1104 to reduce the friction between it and the first ring 5. The second elastic element 1105 is a spring, which is used to apply pressure to the first extrusion rod 1104. There is friction between the first ring 5 and the shell 1. During the sliding of the first rotating plate 602 in the third groove 10083 (the first rotating plate 602 moves upward, and the first elastic element 1101 undergoes axial and circumferential deformation), the first rotating plate 602 drives the moving rod 1103 to move upward together through the second ring 1102. The moving rod 1103 compresses the second elastic element 1105. The second elastic element 1105 applies the generated elastic force to the first extrusion rod 1104, so that the first extrusion rod 1104 squeezes the first ring 5 and increases the friction between the first ring 5 and the pipe 2, thereby overcoming the first During the rotation of the rotating plate 602, the torque generated by the twisting of the first elastic element 1101 causes the first filter element 7 to deform axially and circumferentially. As the first rotating plate 602 continues to rotate counterclockwise, when the limiting protrusion on the first rotating plate 602 enters the second groove 10082, the first rotating plate 602 begins to move downward along the second groove 10082 under the action of the elastic force of the second elastic element 1105. During the process, the moving rod 1103 gradually loses the squeezing of the second elastic element 1105, that is, the squeezing force of the first squeezing rod 1104 on the first ring 5 is reduced. When the friction force between the first ring 5 and the pipe 2 is less than the torque generated by the twisting of the first elastic element 1101, the first ring 5 begins to rotate counterclockwise under the action of the torque of the first elastic element 1101 (gradually moves in the rotation direction of the first rotating plate 602 until the two return to their initial relative state again), thereby completing the deformation and resetting of the first filter element 7.

[0053] like Figure 4-Figure 7 and Fig. 9 As shown, it also includes: a second rotating plate 1201, which is rotatably connected to the rotating shaft 601, the second rotating plate 1201 is equipped with a second telescopic rod 1202, the worm wheel 1005 is provided with a through groove, the second telescopic rod 1202 is located in the through groove of the worm wheel 1005, the first rotating plate 602 is fixedly connected with second limiting members 1203 distributed circumferentially, the second telescopic rod 1202 and the adjacent second limiting members 1203 are mutually limited, and a third elastic element 1204 is fixedly connected between the rotating shaft 601 and the second rotating plate 1201; a locking assembly is arranged on a side of the shell 1 close to the second rotating plate 1201, and is used to change the relative motion state of the second rotating plate 1201 and the shell 1.

[0054] In the above scheme, the cross section of the telescopic end of the second telescopic rod 1202 is a "right-angled trapezoid", the first rotating plate 602 limits the telescopic end of the second telescopic rod 1202, the second limiting member 1203 is provided with an inclined surface (the cross section is a "right-angled trapezoid"), the first limiting member 1007 and the second limiting member 1203 are both made of elastic materials, and the inclined surface on the second limiting member 1203 (first limiting member 1007) squeezes the inclined surface on the telescopic end of the second telescopic rod 1202 (first telescopic rod 1006), so that the second limiting member 1203 (first limiting member 1007) can pass through the adjacent second telescopic rod 12 02 (first telescopic rod 1006), the third elastic element 1204 is a coil spring, which is used to apply torque to the second rotating plate 1201. During the counterclockwise rotation of the rotating shaft 601 (first rotating plate 602), since the second rotating plate 1201 is kept stationary by the locking assembly, the third elastic element 1204 is deformed, and the first rotating plate 602 drives the second limiting member 1203 to rotate counterclockwise together. When the inclined surface on the second limiting member 1203 contacts the inclined surface on the second telescopic rod 1202, the second limiting member 1203 is compressed and deformed until it passes through the second telescopic rod 1202.

[0055] When water from the external water channel no longer flows into the pipe 2, the locking assembly loses the locking of the second rotating plate 1201. Subsequently, the second rotating plate 1201 starts to rotate counterclockwise under the action of the torsional force of the third elastic element 1204. The second rotating plate 1201 drives the second telescopic rod 1202 to rotate counterclockwise together. When the second telescopic rod 1202 contacts the second limiting member 1203 (the right-angled side of the second telescopic rod 1202 contacts the right-angled side of the second limiting member 1203, the tilting member 1207 on the first limiting member 1007 is in the process The inclined surface contacts the inclined surface on the telescopic end of the first telescopic rod 1006, and the first limit piece 1007 is squeezed and deformed, thereby passing through the first telescopic rod 1006). The second telescopic rod 1202 drives the first rotating plate 602 to rotate counterclockwise through the second limit piece 1203, so that the first filter element 7 continues to deform repeatedly and reduces the amount of impurities accumulated on the first filter element 7 due to the first filter element 7 being in the water for a long time when external water does not enter the pipe 2 (that is, the present invention is in a non-working state).

[0056] like Figure 4 , Figure 6 , Fig. 9 and Fig.10As shown, the locking assembly includes: a second extrusion rod 1301, which is slidably connected to one side of the shell 1 close to the second rotating plate 1201, and the second extrusion rod 1301 limits the second rotating plate 1201; a sliding shell 1302, which is slidably connected to one end of the rotating shaft 1001 close to the second extrusion rod 1301, the sliding shell 1302 is splined with the pipe 2, the sliding shell 1302 is fixed to the second extrusion rod 1301, the sliding shell 1302 is filled with a transmission medium, the rotating shaft 1001 is fixed with a third turbine 1303, the third turbine 1303 is located in the sliding shell 1302, and a fourth elastic element 1304 is fixed between the sliding shell 1302 and the pipe 2.

[0057] In the above scheme, the transmission medium in the sliding shell 1302 is hydraulic oil, and the fourth elastic element 1304 is a spring, which is used to reset the sliding shell 1302. During the counterclockwise rotation of the rotating shaft 1001, the rotating shaft 1001 drives the third turbine 1303 to rotate counterclockwise together, and the third turbine 1303 squeezes the hydraulic oil in the sliding shell 1302 to the right. Then the sliding shell 1302 starts to slide to the right along the pipe 2, and the fourth elastic element 1304 is compressed. The sliding shell 1302 drives the second extrusion rod 1301 to move to the right together, and the second extrusion rod 1301 gradually moves with the second rotating shaft 1001. The right part of the plate 1201 is in contact with the sliding shell 1302, and the friction force between the two overcomes the torque applied to the second rotating plate 1201 by the third elastic element 1204 (that is, it realizes constant energy storage for subsequent work). When the rotating shaft 1001 stops rotating counterclockwise, the sliding shell 1302 begins to reset under the action of the elastic force of the fourth elastic element 1304, and the sliding shell 1302 drives the second extrusion rod 1301 to reset together. The second extrusion rod 1301 gradually loses the extrusion on the second rotating plate 1201, and then the second rotating plate 1201 begins to rotate under the action of the torque of the third elastic element 1204.

[0058] like Figure 6 and Fig. 9 As shown, it also includes: a rotating ring 1401, which is fixedly connected to the second rotating plate 1201, the shell 1 is provided with a channel 1402, the channel 1402 is filled with a damping medium, and the rotating ring 1401 slides in the channel 1402; a baffle 1403, which is a plurality of circumferentially spaced distributions, and is used to squeeze the damping medium in the channel 1402, so as to reduce the rotation speed of the second rotating plate 1201 when the third elastic element 1204 acts on it, and is all fixedly connected to the rotating ring 1401. The baffle 1403 is located in the channel 1402, and also includes: an annular member 1404, which is a plurality of circumferentially spaced distributions, and is all fixedly connected to the channel 1402. The baffle 1403 and the annular member 1404 are always not in contact, and are used to make the damping medium in the channel 1402 tend to be stable.

[0059] In the above scheme, the damping medium in the channel 1402 is hydraulic oil. During the counterclockwise rotation of the second rotating plate 1201, the second rotating plate 1201 drives the rotating ring 1401 to rotate counterclockwise together. The rotating ring 1401 drives the baffle 1403 to start moving in the channel 1402. During the process, the baffle 1403 is hindered by the hydraulic oil in the channel 1402, so that the counterclockwise rotation speed of the second rotating plate 1201 is relatively slowed down, thereby extending the rotation time of the second rotating plate 1201, and then extending the time that the first filter element 7 is in a deformed state, thereby improving the effect of shedding impurities thereon.
