Description

Technical Field

[0002] Wastewater treatment refers to the process of treating wastewater using physical, chemical and biological methods to purify it, reduce pollution, and even recycle and reuse wastewater to make full use of water resources. Wastewater filtration facilities are facilities for removing suspended matter in wastewater and can be used for pretreatment or final treatment of wastewater. Wastewater passes through porous filter media or facilities, and suspended matter larger than the pore size is retained, so that the wastewater is purified to a certain extent. Filter media or facilities include grids, screens, sand, filter cloths, microporous tubes, etc., which are mainly used to retain finer suspended matter such as fibers in wastewater. The retained matter can be recovered by washing with water.

[0003] In the process of treating wastewater, the filter element will accumulate a lot of impurities over time, which not only reduces the filtering efficiency of the wastewater, but also affects the circulation and production of clean water. At this time, the filter needs to be cleaned, but because it is a filtration for treating wastewater, and there are many impurities in the wastewater, the filter element needs to be replaced more frequently. If the filter is manually taken out for cleaning and then put back, it is time-consuming and laborious, and requires multiple frequent maintenance, which increases the maintenance cost and brings certain adverse effects to people's use process.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, a mobile component is provided. When the mobile component is moved to the right side to the connection between the clean water pipe and the tubular shell under water pressure, the clean water pipe is blocked, so that the waste water flows out through the sewage pipe, and the unfiltered impurities flow out through the sewage pipe along with the water flow, thereby realizing self-cleaning.

[0021] 4. In the present invention, the clamping block is clamped on the outer surface of the clamping groove, thereby separating the filter element from the movable assembly. The loading cylinder controls the loading rack to push out the filter element on the left side of the fixed frame, so that the filter element enters the interior of the filter assembly through the connecting groove, and the first magnet ring and the second magnet ring are magnetically attracted to complete the installation of the movable assembly and the new filter element, realizing automatic replacement of the filter element, reducing the maintenance of the operator, saving manpower and time, and thus reducing maintenance costs.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Embodiment 1, as Figure 1 - Figure 5 As shown, a wastewater filtering device with automatic filter element replacement includes a filter assembly 1, a core storage assembly 2 is fixedly connected inside the filter assembly 1, a replacement assembly 4 is fixedly connected to the left side of the filter assembly 1, and a placement assembly 3 is detachably installed on the upper end of the core storage assembly 2;

[0036] like Figure 2 - Figure 5As shown, the filter assembly 1 includes a tubular shell 11, a water inlet pipe 12 is fixedly connected to the left side of the lower end of the tubular shell 11, an auxiliary water pipe 13 is fixedly connected to the right side of the water inlet pipe 12, a switch valve 118 is arranged inside the auxiliary water pipe 13, one end of the auxiliary water pipe 13 is fixedly connected to the right side of the lower end of the tubular shell 11, a sewage pipe 15 is fixedly connected to the right side of the upper end of the tubular shell 11, and a clean water pipe 16 is fixedly connected to the right side of the upper end of the tubular shell 11. The clean water pipe 16 is located on the right side of the sewage pipe 15. On the side, the connection between the auxiliary water pipe 13 and the tubular shell 11 is located between the sewage pipe 15 and the clean water pipe 16, the right end of the tubular shell 11 is fixedly connected with a pushing cylinder 14, the right end of the inner wall of the tubular shell 11 is fixedly connected with an embedded block 116, one end of the pushing cylinder 14 is fixedly connected with a third magnet block 117, the outer surface of the embedded block 116 is movably sleeved with a pushing spring 115, the interior of the tubular shell 11 is movably sleeved with a moving component 5, and the interior of the tubular shell 11 is movably sleeved with a filter element 6.

[0037] By using the embedded block 116 , when the moving assembly 5 moves to the right, the embedded groove 53 will be sleeved on one side of the embedded block 116 , so that the waste water cannot flow into the clean water pipe 16 through the inside of the flow groove 54 , thereby preventing the waste water from flowing out of the clean water pipe 16 .

[0038] like Fig. 9 As shown, the moving component 5 includes a connecting inner tube 51, which is movably sleeved inside the tubular shell 11, and a piston ring 52 is fixedly sleeved on the outer surface of the connecting inner tube 51. A connecting frame 55 is fixedly connected to the left end of the connecting inner tube 51, and a first magnet ring 56 is fixedly connected to the left side of the connecting frame 55. An embedded groove 53 is provided on the right side of the connecting inner tube 51, and a flow groove 54 is provided inside the connecting inner tube 51. The embedded groove 53 is movably sleeved on one end of the embedded block 116, and the flow groove 54 is movably sleeved on the outer surface of the third magnet block 117, and the third magnet block 117 is magnetically connected to the first magnet ring 56.

[0039] Through the magnetic attraction between the third magnet block 117 and the first magnet ring 56, the movement of the third magnet block 117 is controlled by pushing the cylinder 14, and through the magnetic attraction between the third magnet block 117 and the first magnet ring 56, the moving component 5 slides inside the tubular shell 11 as the third magnet block 117 moves.

[0040] By utilizing the effect of the piston ring 52, when the movable component 5 drives the piston ring 52 to move to the left, and the piston ring 52 moves to the connection between the sewage pipe 15 and the tubular shell 11, the sewage pipe 15 is blocked, so that the waste water is filtered by the movable component 5 and then flows out from the clean water pipe 16. When the movable component 5 moves to the right side to the connection between the clean water pipe 16 and the tubular shell 11, the clean water pipe 16 is blocked, so that the waste water flows out through the sewage pipe 15, and the unfiltered impurities flow out through the sewage pipe 15 with the water flow, realizing self-cleaning. By moving the movable component 5, the flow direction of the waste water is realized. On the one hand, the waste water can be filtered, and on the other hand, self-cleaning can be realized, thereby reducing the replacement of the filter element 6 and extending the time for later maintenance.

[0041] Embodiment 2, as Figure 1 - Figure 8 As shown, a wastewater filtering device with automatic filter element replacement, the core storage assembly 2 includes a fixed block 21, the upper end of the fixed block 21 is fixedly connected to a storage box 22, the right side of the storage box 22 is fixedly connected to a convex ring 27, the left side of the top of the storage box 22 is fixedly connected to a loading cylinder 23, the bottom of the loading cylinder 23 is fixedly connected to a loading rack 24, a cavity is opened inside the storage box 22, the loading rack 24 is embedded and installed at the upper end of the internal cavity of the storage box 22, a push switch 26 is arranged on the left side of the inner wall of the cavity, an indicator light 28 is fixedly connected to the top of the storage box 22, the indicator light 28 is electrically connected to the push switch 26, a connecting groove 25 is opened at the bottom of the left side of the storage box 22, and the loading rack 24 is located at the top of the connecting groove 25.

[0042] Through the action of the push switch 26, when the placement component 3 is installed inside the core storage component 2, the filter element 6 inside the fixed frame 36 will be squeezed to one side of the push switch 26, so that the push switch 26 is always in a pressed state. At this time, the indicator light 28 will go out. When the filter element 6 inside the fixed frame 36 is used up, the side of the push switch 26 is not squeezed. At this time, the push switch 26 makes the indicator light 28 light up, thereby reminding the operator to replace the new filter element 6 in time. Through the reminder of the indicator light 28, the operator can quickly understand the current usage of the filter element 6 inside the wastewater filter device, so as to maintain the wastewater filter device in time.

[0043] The fixing block 21 is fixedly sleeved on the outer surface of the left side of the tubular shell 11 , and the cavity inside the storage box 22 is connected with the tubular shell 11 through the connecting groove 25 .

[0044] like Figure 7As shown, the placement component 3 includes a fixed cover 31, the right side of the fixed cover 31 is fixedly connected to a support tube 32, the support tube 32 has an internal movable sleeve with an extrusion column 33, the support tube 32 has an internal movable sleeve with an extrusion spring 34, the extrusion spring 34 is located between the extrusion column 33 and the inner wall of the support tube 32, and both ends of the left side of the fixed cover 31 are fixedly connected to a fixed frame 36, and the fixed frame 36 is made of elastic material.

[0045] The fixing cover 31 is movably sleeved on the outer surface of the convex ring 27 , a rubber sealing ring 37 is embedded in the fixing cover 31 , a locking bolt 35 is threadedly installed on the outer side of the fixing cover 31 , and the fixing cover 31 is detachably mounted on the outer surface of the convex ring 27 through the locking bolt 35 .

[0046] When the plurality of filter elements 6 are clamped in the interior of the fixed frame 36 by utilizing the function of the fixed frame 36, the extrusion column 33 squeezes the plurality of filter elements 6 in the interior of the fixed frame 36 through the reaction force of the extrusion spring 34, thereby realizing the storage of the plurality of filter elements 6. When the fixed frame 36 is embedded in the cavity inside the storage box 22, the filter element 6 inside the fixed frame 36 is always in the state of pressing the press switch 26. When the loading cylinder 23 controls the loading rack 24 to push out the filter element 6 on the left side of the fixed frame 36, the filter element 6 enters the interior of the filter assembly 1 through the connecting groove 25. The extrusion spring 34 on the right side pushes the other filter elements 6 to move to the left through the extrusion column 33 through the reaction force, so that the filter element 6 inside the fixed frame 36 is timely added to the top of the connecting groove 25, so that the loading rack 24 can load the filter element 6.

[0047] like Figure 8 As shown, there are multiple filter elements 6, and the multiple filter elements 6 include a filter element ring 61. The outer surface of the filter element ring 61 is provided with a snap-in groove 62. A filter element 64 is fixedly connected to the left side of the inside of the filter element ring 61. A second magnet block 63 is fixedly sleeved inside the filter element 64. A second magnet ring 65 is fixedly connected to the inner wall of the filter element ring 61. The filter element ring 61 is movably sleeved on the outer surface of the first magnet ring 56. The second magnet ring 65 is magnetically connected to the first magnet ring 56. One side of the second magnet block 63 is magnetically connected to the first magnet block 111. The snap-in block 110 is snap-fitted and installed inside the snap-in groove 62.

[0048] By utilizing a plurality of filter elements 6, the filter element 6 can be automatically replaced through a wastewater filtering device, and by storing the filter elements 6, the number of times the operator replaces the filter element 6 can be reduced, thereby reducing manpower maintenance of the wastewater treatment device, extending the maintenance time, saving manpower and time, and reducing subsequent maintenance costs.

[0049] Through the inclined surface on the right side of the clamping block 110, when the movable component 5 pushes the filter element 6 to move to the left, the filter element 6 moves to the right side of the clamping block 110, pushing the clamping block 110 to move toward the inside of the side block 18, and through the action of the clamping spring 19, the clamping block 110 is clamped on the outer surface of the clamping groove 62, thereby separating the filter element 6 from the movable component 5. During this process, when the movable component 5 pushes another filter element 6 to move to the side of the clamping block 110, the other filter element 6 can push the filter element 6 clamped by the clamping block 110 to move to the left, and the other filter element 6 will be clamped inside the clamping block 110, thereby causing multiple filter elements 6 to accumulate inside the left side of the tubular shell 11.

[0050] Embodiment three, as Figure 1 - Fig.10 As shown, a wastewater filtering device for automatically replacing filter elements, the replacement component 4 includes a replacement box 41 fixedly installed on the left side of the tubular shell 11, a replacement frame 42 is embedded in the top of the replacement box 41, a waste core cover 43 is fixedly connected to the top of the replacement frame 42, a sealing ring is embedded in the bottom of the waste core cover 43, and the waste core cover 43 is fixedly installed on the top of the replacement box 41 by bolts, a replacement groove 44 is opened on the right side of the replacement frame 42, and a movable hole 45 is opened inside the replacement groove 44, the filter element 6 is movably sleeved inside the replacement groove 44, and the movable hole 45 is movably sleeved on the outer surface of the first magnet block 111.

[0051] The left side of the tubular shell 11 is fixedly connected to a replacement cylinder 17 , and one side of the replacement cylinder 17 is fixedly connected to a first magnet block 111 .

[0052] Among them, the four sides of the tubular shell 11 close to one end of the replacement cylinder 17 are fixedly connected with the side block 18, the internal movable sleeve of the side block 18 is connected with the clamping block 110, one side of the clamping block 110 is fixedly connected with the clamping spring 19, the other end of the clamping spring 19 is fixedly connected to the inner wall of the side block 18, and the side of the clamping block 110 away from the replacement cylinder 17 is an inclined surface.

[0053] Through the action of the replacement cylinder 17 and the first magnet block 111, when the first magnet block 111 passes through the inside of the movable hole 45 to the side of the filter element 64, the replacement cylinder 17 contracts through the magnetic attraction of the first magnet block 111 and the second magnet block 63, and the first magnet block 111 drives the filter element 6 to move to the inside of the replacement groove 44, and through the action of the movable hole 45, the first magnet block 111 and the second magnet block 63 are separated, so that the filter element 6 stays in the inside of the replacement groove 44, and the replacement frame 42 is taken out through the waste core cover 43, and the filter element 6 inside the replacement groove 44 is taken out to realize the recovery of the waste filter element 6.

[0054] It should be noted that the present invention is a wastewater filter device with automatic filter element replacement. When in use, wastewater enters the interior of the tubular shell 11 through the water inlet pipe 12, and the wastewater is filtered through the filter element 64, and passes through the flow groove 54 inside the connecting inner tube 51, and flows out from the clean water pipe 16 through the embedded groove 53 to filter the wastewater. At this time, the connecting inner tube 51 is located in the middle of the tubular shell 11, and the piston ring 52 is located on one side of the sewage pipe 15 and the auxiliary water pipe 13. The auxiliary water pipe 13 and the sewage pipe 15 cannot circulate. As time accumulates, the impurities in the filter element 64 increase and block the filter element 64. At this time, the wastewater cannot flow out through the filter element 64, and the water pressure will push the filter element 64 to move to the right inside the tubular shell 11, pushing the spring 115 to be squeezed and compressed;

[0055] When the moving assembly 5 moves to the right side of the tubular shell 11, the embedded groove 53 is sleeved on the outer surface of one end of the embedded block 116. At this time, the pushing spring 115 is in a compressed state, and the piston ring 52 moves to one side of the clean water pipe 16 to block the clean water pipe 16. At this time, the filter element 64 is located on the right side of the sewage pipe 15, and one end of the auxiliary water pipe 13 is located on the side of the connecting frame 55. The wastewater passes through the surface of the filter element 64 and flows out through the sewage pipe 15, taking away the impurities that have not passed through the filter element 64, and the wastewater in the auxiliary water pipe 13 passes through the right side of the filter element 64 to reversely flush the filter element 64, so that the impurities inside the filter element 64 are flushed out, and the filter element 6 is backwashed. After the filter element 64 is automatically cleaned, the water pressure is reduced. At this time, the reaction force of the pushing spring 115 is used to push the moving assembly 5 and the filter element 6 to move to the left again, and the wastewater is filtered again through the filter element 6, so that the wastewater can achieve a short self-cleaning, extend the replacement time of the filter element, and improve the performance of the device;

[0056] When the clean water pipe 16 cannot flow out the clean water and the filter element 6 needs to be replaced, the switch valve 118 is closed, and the pushing cylinder 14 is started to extend the pushing cylinder 14, and the third magnet block 117 is magnetically attracted to the first magnet ring 56 through the flow groove 54, and then the moving assembly 5 is pushed to move to the left, and the first magnet ring 56 pushes the filter element ring 61 to move to the left, and the clamping block 110 is squeezed by the filter element ring 61, and the clamping block 110 shrinks to the inside of the side block 18. When the clamping groove 62 reaches the side of the side block 18, the reaction force of the clamping spring 19 makes the clamping block 110 clamped in the inside of the clamping groove 62, and then the pushing cylinder 14 shrinks, and the third magnet block 117 drives the moving assembly 5 to move to the left, and the filter element 6 is clamped by the clamping block 110. , stays on the left side of the tubular shell 11, the feeding cylinder 23 controls the feeding rack 24 to descend, so that the filter element 6 on the left side of the fixed frame 36 is lowered through the feeding rack 24, and the filter element ring 61 is pushed down to the inside of the tubular shell 11, and the pushing cylinder 14 is extended, so that the first magnet ring 56 and the second magnet ring 65 are magnetically attracted, and the installation of the moving component 5 and the new filter element 6 is completed. Finally, through the magnetic attraction of the third magnet block 117 and the first magnet ring 56, the moving component 5 is moved to the right side of the tubular shell 11 through the contraction of the third magnet block 117. Through the reaction force of the push spring 115, the third magnet block 117 is separated from the first magnet ring 56, so that the connecting inner tube 51 stays inside the tubular shell 11, and the filter element 6 is located on the right side of the water inlet pipe 12;

[0057] When the filter elements 6 inside the fixing frame 36 are all loaded, at this time, when the pressing switch 26 is not subjected to the squeezing force, the indicator light 28 will light up, and then, the fixing cover 31 is taken out by the locking bolt 35, and a plurality of new filter elements 6 are replaced, so that the plurality of filter elements 6 are embedded in the interior of the fixing frame 36, and through the action of the squeezing spring 34, the plurality of filter elements 6 are squeezed into the interior of the fixing frame 36 by the squeezing column 33, so that the plurality of filter elements 6 are fixed in the interior of the fixing frame 36, and the plurality of filter elements 6 inside the fixing frame 36 are placed in the cavity inside the storage box 22, and are squeezed to the side of the pressing switch 26 by the filter elements 6. At this time, the pressing switch 26 is subjected to pressure, and the placing component 3 is fixed to the interior of the storage core component 2 by the locking bolt 35, and the indicator light 28 is extinguished. By pressing the switch 26 and the indicator light 28, the use of the inside of the placing component 3 can be directly observed, so that it is convenient for the operator to replace the new filter element 6 in time.

[0058] When the used filter element 6 needs to be cleaned, the first magnet block 111 is moved to the side of the filter element 64 to adsorb the second magnet block 63 by extending the replacement cylinder 17, and the first magnet block 111 drives the filter element 6 to move to the replacement slot 44 inside the replacement frame 42 by contracting the replacement cylinder 17. As the replacement cylinder 17 contracts, the filter element 6 stays inside the replacement frame 42, and the used core cover 43 is removed by removing the bolts, and the used filter element 6 is removed through the replacement frame 42, thereby realizing the recovery and replacement of the used filter element 6.
