Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a sewage filtering device. Background Art

[0002] Wastewater often contains various impurities, such as branches, plastic bags, cloth, sand and gravel, etc. If these impurities are not filtered, they will enter the subsequent treatment equipment (such as pumps, sedimentation tanks, activated sludge reactors, etc.), which may easily cause blockage, wear or damage to these equipment.

[0003] When existing sewage treatment plants perform coarse filtration on sewage, sewage treatment screen machines are usually used to filter coarse impurities. However, when the sewage treatment screen machine filters flexible floating objects (such as plastic bags, cloth strips) and particulate impurities in sewage, these impurities are easily entangled and stuck on the screen of the sewage treatment screen machine, thereby blocking the screen in the area. Therefore, the sewage treatment screen machine needs to be cleaned and maintained more frequently. In addition, the existing sewage treatment screen machine cannot effectively process large-volume sand, gravel, silt and other sediments. Therefore, it is necessary to leave more space at the bottom of the sewage treatment screen machine so that large-volume sand, gravel, silt and other sediments in the sewage are enclosed and retained in the space. After the sewage filtration is completed, the sediment in the space is salvaged. This method is time-consuming and labor-intensive, thus affecting the filtration efficiency of the sewage.

[0008] In addition, the sewage filtration device proposed in the present application may also have the following additional technical features:

[0009] In one embodiment of the present application, the mounting member includes a rotating cylinder, a limiting rod and a fixed block, wherein the rotating cylinder is rotatably set on the reciprocating screw rod; one end of the limiting rod is connected to the rotating cylinder, and the other end of the limiting rod is slidably connected to the second tube body; the fixed block is set on the rotating cylinder.

[0010] In one embodiment of the present application, the plug-in mechanism includes a ring, a torsion spring, a support plate and a plurality of elastic plug-in parts, wherein the ring is rotatably set on the mounting part; one end of the torsion spring is connected to the ring, and the other end of the torsion spring is connected to the mounting part; the support plate is set on the ring; the plurality of elastic plug-in parts are respectively set on the support plate, and the plurality of elastic plug-in parts are respectively plugged into the corresponding filter holes.

In addition, the rotation setting of the plug-in mechanism on the mounting part puts the plug-in mechanism and the filter plate in a plug-in state, and when the filter plate rotates, the plug-in mechanism can rotate with the filter plate, thereby ensuring the plug-in and dredging effect of the plug-in mechanism on the filter holes, and can clean the filter holes during operation, so that the device does not require frequent cleaning and maintenance.

[0017] By arranging the box at the bottom of the first tube and connecting it to the second discharge hole, the discharge, deposition, and cleaning of sediment are facilitated. The rotation of the filter plate drives the first lever, which in turn drives the discharge assembly to slide along the bottom of the box, discharging sediment from the bottom of the box. This allows the cleaning and filtration of sediments such as sand, gravel, and silt during operation, thereby improving sewage filtration efficiency.

DETAILED DESCRIPTION

[0031] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0032] The sewage filtering device according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0033] like Figures 1-10 As shown, the sewage filtering device of the embodiment of the present application may include a first tube body 1, a second tube body 3, a filter plate 2, a motor 4, a reciprocating screw 5, a pore-clearing component 6 and a cleaning component 7.

[0034] The first tube body 1 is connected to the second tube body 3 .

[0035] It should be noted that the first tube body 1 and the second tube body 3 described in this embodiment are respectively laid on the ground, and the first tube body and the second tube body 3 are set with top openings to facilitate the flow of impurities. In addition, a water outlet 30 is provided at the bottom of the second tube body 3 to facilitate the sewage after filtering out impurities to flow out of the second tube body 3 to other treatment equipment for treatment.

[0036] The first tube body 1 is provided with a first discharge port 10 and a second discharge port 11 , which are respectively located at the water outlets where the first tube body 1 and the second tube body 3 are connected.

[0037] It should be noted that the water outlet described in this embodiment refers to the end where sewage enters the first tube body 1 as the water inlet, and the end where sewage flows out of the first tube body 1 as the water outlet.

[0038] In the embodiment of the present application, the first discharge port 10 is used to discharge floating impurities (such as plastic bags, cloth strips, etc.) in sewage.

[0039] In the embodiment of the present application, the second discharge port 11 is used to clean and discharge sediment in sewage.

[0040] It should be noted that, in this embodiment, impurity collection boxes are provided at the first discharge port 10 and the second discharge port 11, so as to facilitate the collection of impurities in the sewage.

[0041] It should be noted that the first discharge port 10 described in this embodiment is designed to be concave downward at the top of the first tube body 1, so as to facilitate the discharge of floating objects, and the second discharge port 11 is opened at the bottom of the first tube body 1, so as to facilitate the deposition and discharge of sediments.

[0042] The filter plate 2 is arranged at the water outlet of the first tube body 1. A plurality of filter holes 20 are opened on the filter plate 2. A blanking plate 22 is arranged on one side of the filter plate 2. The blanking plate 22 is located on one side of the first blanking port 10. A first shift rod 21 is arranged on the other side of the filter plate 2.

[0043] It should be noted that the discharge plates 22 described in this embodiment are provided with multiple ones, thereby improving the discharge efficiency of floating impurities, and leakage holes 220 are opened on the discharge plates 22 to facilitate the discharge of impurities and prevent the discharge plates 22 from pushing impurities and a large amount of sewage out at the same time.

[0044] It can be understood that by rotating the filter plate 2 and setting it on the first tube body 1, flexible impurities such as cloth strips and plastic bags can be prevented from being entangled in the device, and the rotating filter plate 2 can rotate the filter holes 20 in different areas to the sewage inflow point of the first tube body 1, thereby preventing the filter holes 20 from being blocked due to long-term use, and can avoid the situation where impurities such as cloth strips are pressed tightly against the filter plate 2 under the impact of water flow, thereby blocking the filter holes 20. Impurities such as cloth strips that are pressed tightly against the filter plate 2 gradually move toward the top of the filter plate 2 under the rotation of the filter plate 2, and slide and fall into the first tube body 1 or onto the discharge plate 22 under the action of gravity, and are pushed by the discharge plate 22 to be discharged from the first discharge port 10, thereby improving the filtration efficiency of sewage.

[0045] It can be understood that by setting up multiple filter holes 20 on the filter plate 2, impurities in the sewage can be blocked and filtered, and the filter plate 2 is rotatably sealed and connected to the water outlet of the first tube body 1, thereby preventing impurities in the sewage from leaking from the gap between the filter plate 2 and the first tube body 1, thereby ensuring the filtration quality of sewage impurities.

[0046] It can be understood that through the setting of the blanking plate 22, when the filter plate 2 rotates, one end of the blanking plate 22 rotates into the first tube body 1, and pushes the floating impurities blocked at the filter plate 2, and pushes the floating impurities to the first blanking port 10 for blanking.

[0047] The motor 4 is arranged on the second tube body 3 , and the output shaft of the motor 4 is connected to the reciprocating screw 5 . One end of the reciprocating screw 5 is rotatably connected to the second tube body 3 , and the other end of the reciprocating screw 5 is connected to the filter plate 2 .

[0048] It can be understood that the motor 4 drives the reciprocating screw 5 to rotate, which can drive the pore-clearing component 6 to rotate on the reciprocating screw 5, thereby facilitating the pore-clearing component 6 to clear the filter holes 20. In addition, the rotation of the reciprocating screw 5 can drive the filter plate 2 to rotate, so that different filter areas on the filter plate 2 rotate to filter impurities in the sewage, preventing impurities such as cloth from sticking to the filter holes 20 under the impact of the water flow, resulting in large-scale blockage of the filter holes 20, thereby ensuring the filtration efficiency of the sewage.

[0049] The pore-clearing component 6 may include a mounting member 60 and a plug-in mechanism 61 .

[0050] The mounting member 60 is sleeved on the reciprocating screw rod 5 , the mounting member 60 is slidably connected to the second tube body 3 , and the plug-in mechanism 61 is rotatably provided on the mounting member 60 and slidably plugged into the filter hole 20 .

[0051] It can be understood that, through the setting of the mounting member 60, the motor 4 rotates to drive the reciprocating screw 5 to rotate, and drives the mounting member 60 to move back and forth on the reciprocating screw 5, thereby controlling the reciprocating movement of the plug-in mechanism 61, so that the plug-in mechanism 61 slides and plugs the filter cylinder on the filter plate 2, thereby casting out the impurities in the filter hole 20 and dredging the filter hole 20. In addition, the rotation setting of the plug-in mechanism 61 on the mounting member 60 makes the plug-in mechanism 61 and the filter plate 2 in a plug-in state, and when the filter plate 2 rotates, the plug-in mechanism 61 can rotate with the filter plate 2, thereby ensuring the plug-in and dredging effect of the plug-in mechanism 61 on the filter hole 20.

[0052] The cleaning assembly 7 may include a box body 70 and a blanking assembly 71 .

[0053] Among them, the box body 70 is arranged at the bottom of the first tube body 1 and is connected to the second discharge port 11. The discharge component 71 is slidably arranged on the inner bottom side of the box body 70 and is slidably and sealedly connected to the discharge port 700 opened on the box body 70. The first shift rod 21 is rotatably abutted with the discharge component 71 and drives the discharge component 71 to discharge the sediment in the box body 70.

[0054] In the embodiment of the present application, the discharge assembly 71 is used to slide and discharge the sediment in the box body 70, and the discharge can be performed while the sediment in the sewage is continuously deposited, without affecting the filtration efficiency of the sewage.

[0055] It can be understood that by arranging the box body 70 at the bottom of the first tube body 1 and communicating with the second discharge port 11, the discharge, deposition and cleaning of the sediment are facilitated.

[0056] It is understandable that the rotation of the filter plate 2 drives the first lever 21 to rotate, and the rotation of the first lever 21 drives the blanking assembly 71 to slide on the bottom side of the box body 70 and slide and discharge the sediment on the bottom side of the box body 70.

[0057] Specifically, during the actual operation, sewage flows from the first pipe body 1 into the second pipe body 3, and the relevant staff starts the motor 4. The motor 4 drives the reciprocating screw 5 to rotate, and drives the filter plate 2 to rotate on the first pipe body 1. The filter holes 20 on the filter plate 2 filter impurities in the sewage and block the impurities on the first pipe body 1. The rotation of the filter plate 2 drives the discharge plate 22 to rotate, and the discharge plate 22 pushes the floating impurities to the first discharge port 10 for discharge. In addition, deposited impurities such as sand, gravel and silt fall to the bottom of the box 70. During the rotation of the filter plate 2, the first lever 21 drives the discharge assembly 71 to slide in the box 70, thereby cleaning and discharging the sediment at the bottom of the box 70.

[0058] The motor 4 drives the reciprocating screw 5 to rotate, and the reciprocating screw 5 rotates, driving the mounting frame to move back and forth on the reciprocating screw 5 and the second tube body 3, and driving the plug-in mechanism 61 to move back and forth, and reciprocatingly plugging the rotating filter hole 20 on the filter plate 2, thereby casting out impurities in the filter hole 20, and eliminating the need for frequent maintenance and cleaning of the device.

[0059] In one embodiment of the present application, Figure 1 and Figure 5 As shown, the mounting member 60 may include a rotating cylinder 600 , a limiting rod 601 and a fixing block 602 .

[0060] Among them, the rotating cylinder 600 is rotatably set on the reciprocating screw rod 5, one end of the limiting rod 601 is connected to the rotating cylinder 600, the other end of the limiting rod 601 is slidably connected to the second tube body 3, and the fixing block 602 is set on the rotating cylinder 600.

[0061] It is understandable that, by setting the limiting rod 601 , the rotating cylinder 600 can be limited to prevent the rotating cylinder 600 from rotating along with the reciprocating screw 5 , thereby ensuring the linear reciprocating movement effect of the rotating cylinder 600 .

[0062] In one embodiment of the present application, Figure 1 and Figure 5 As shown, the plug-in mechanism 61 may include a collar 610 , a torsion spring 611 , a support plate 612 and a plurality of elastic plug-in members 613 .

[0063] Among them, the ring 610 is rotatably set on the mounting member 60, one end of the torsion spring 611 is connected to the ring 610, the other end of the torsion spring 611 is connected to the mounting member 60, the support plate 612 is set on the ring 610, and multiple elastic plug-ins 613 are respectively set on the support plate 612, and the multiple elastic plug-ins 613 are respectively connected to the corresponding filter holes 20.

[0064] It can be understood that, by the rotation setting of the ring 610 on the mounting member 60, the elastic connector 613 and the filter plate 2 are in a plug-in state, and when the filter plate 2 rotates, the elastic connector 613 drives the ring 610 to rotate on the mounting member 60, so that it can rotate with the filter plate 2, thereby ensuring the plug-in and dredging effect of the elastic connector 613 on the filter hole 20.

[0065] It can be understood that, by setting the torsion spring 611, the support plate 612 and the elastic connector 613 can be limited to prevent the elastic abutment from abutting against the non-filter hole 20 on the filter plate 2 and continuing to rotate with the filter plate 2 when the filter plate 2 rotates. Moreover, by setting the torsion spring 611, when the elastic connector 613 and the filter plate 2 are in the plugged-in state, it can still rotate with the filter plate 2, thereby ensuring the plug-in and dredging effect of the elastic connector 613 on the filter hole 20.

[0066] In one embodiment of the present application, Figure 1 、 Figure 5 and Figure 8 As shown, the elastic connector 613 may include a fixing tube 6130 , a telescopic rod 6131 and a plug spring 6132 .

[0067] Among them, the fixed cylinder 6130 is set on the support plate 612, one end of the telescopic rod 6131 is slidably set in the support plate 612, the other end of the telescopic rod 6131 is slidably plugged into the filter hole 20, the plug-in spring 6132 is located in the fixed cylinder 6130, and one end of the plug-in spring 6132 is connected to the fixed cylinder 6130, and the other end of the plug-in spring 6132 is connected to the telescopic rod 6131.

[0068] It should be noted that the fixed cylinder 6130 described in this embodiment is arranged in the support plate 612 and on the side of the support plate 612 away from the filter plate 2, and the telescopic rod 6131 is arranged on the side of the support plate 612 close to the filter plate 2. When the telescopic rod 6131 abuts against the support plate 612, because the fixed cylinder 6130 is arranged on the side of the support plate 612 away from the filter plate 2, the gap between the support plate 612 and the filter plate 2 is greatly shortened, and the protruding length of the telescopic rod 6131 in the filter hole 20 is increased, ensuring that the telescopic rod 6131 is plugged into and unblocked the filter hole 20.

[0069] In one embodiment of the present application, Figure 2 、 Figure 9 and Figure 10 As shown, the blanking assembly 71 may include a baffle plate 710 , a guide plate 711 , a blanking block 712 and a return spring 713 .

[0070] The baffle plate 710 is arranged inside the box body 70, and the baffle plate 710 is located on one side of the discharge port 700. The guide plate 711 is arranged inside the box body 70 and on one side of the baffle plate 710. The blanking block 712 is slidably arranged on the bottom side of the interior of the box body 70 and is respectively slidably and sealedly connected to the baffle plate 710 and the guide plate 711. A blanking through hole 7120 is opened on the blanking block 712, and the blanking through hole 7120 is slidably connected to the interior of the box body 70, and the blanking through hole 7120 is connected to the interior of the box body 70. The hole 7120 can slide to the outside of the box body 70, and a second lever 7121 is provided on the blanking block 712. The second lever 7121 extends to the outside of the box body 70 through the sliding control hole 701 opened in the box body 70, and the first lever 21 and the second lever 7121 are rotated and abutted. The blanking block 712 slides to seal the discharge port 700 and the sliding control hole 701 respectively, and one end of the return spring 713 is connected to the second lever 7121, and the other end of the return spring 713 is connected to the box body 70.

[0071] It can be understood that, through the setting of the baffle plate 710, when the discharge block 712 slides the sediment in the discharge hole 7120 to the discharge port 700 and discharges the material, it can prevent the sewage in the box body 70 from flowing out through the discharge hole 7120 and the discharge port 700. In addition, the upper end of the baffle plate 710 is set at an angle, so as to facilitate the sediment in the box body 70 to fall directly from the baffle plate 710 into the discharge hole 7120.

[0072] It can be understood that, through the setting of the guide plate 711, the sediment deposited in the box body 70 can be controlled to slide directly from the guide plate 711 to the discharge hole 7120, and through the setting of the guide plate 711, when the discharge block 712 slides the sediment in the discharge hole 7120 to the discharge port 700 and discharges the sediment, one end of the discharge block 712 continues to slide and seal with the guide plate 711, thereby preventing one end of the discharge block 712 from sliding out of the discharge port 700 and forming a gap between the other end and the box body 70, causing the sediment to fall into this area, making it impossible for the discharge block 712 to be reset or unable to discharge the sediment.

[0073] In one embodiment of the present application, Figure 1 and Figure 2 As shown, a material-moving member 12 is provided on the first tube body 1 , and the material-moving member 12 may include a mounting block 120 and a material-moving rod 121 .

[0074] The mounting block 120 is disposed on the first tube body 1 , one end of the material-moving rod 121 is disposed on the mounting block 120 , and the other end of the material-moving rod 121 is rotatably abutted against the filter plate 2 .

[0075] It should be noted that one end of the blanking plate 22 described in this embodiment is arranged at the center of the filter plate 2, and a gap is left between the other end of the blanking plate 22 and the filter plate 2, and the material rod 121 can clean the impurities on the filter plate 2 through the gap, thereby ensuring the filtration efficiency of the sewage.

[0076] Specifically, in the actual operation process, sewage flows from the first pipe body 1 into the second pipe body 3, and the relevant staff starts the motor 4, which drives the reciprocating screw 5 to rotate, and drives the filter plate 2 to rotate on the first pipe body 1. The filter holes 20 on the filter plate 2 filter impurities in the sewage and block the impurities on the first pipe body 1. The rotation of the filter plate 2 drives the discharge plate 22 to rotate, and the discharge plate 22 pushes the floating impurities to the first discharge port 10 for discharge. In addition, the deposited impurities such as sand, gravel and silt fall into the discharge through hole 7120 of the discharge block 712, and the first shift rod 21 performs a circular motion on the filter plate 2. The first When the lever 21 gradually rotates to the bottom of the filter plate 2, it gradually abuts against the second lever 7121 and toggles the second lever 7121. The second lever 7121 drives the discharge block 712 to slide at the bottom of the box body 70 and pushes the impurities deposited in the discharge through hole 7120 to the discharge port. The first lever 21 is continued to be driven by the filter plate 2 and gradually moves toward the top of the filter plate 2, so that the first lever 21 gradually disengages from the second lever 7121. The discharge block 712 returns to its initial position under the pull of the return spring 713, and the above operation is repeated, so that the sediment in the box body 70 is continuously discharged during the continuous filtration of sewage.

[0077] The motor 4 drives the reciprocating screw 5 to rotate, and the reciprocating screw 5 rotates, driving the mounting frame to move back and forth on the reciprocating screw 5 and the second tube body 3, and driving the fixed cylinder 6130 and the support plate 612 to move back and forth, and making the support plate 612 slide back and forth to one side of the filter plate 2, driving the elastic connector 613 to reciprocately connect the filter hole 20 on the filter plate 2, thereby casting out the impurities in the filter hole 20, and eliminating the need for frequent maintenance and cleaning of the device.

[0078] In summary, the sewage filtration device of the embodiment of the present application can automatically clean the filter holes during operation, thereby solving the problem of frequent cleaning and maintenance of the sewage treatment screen machine. In addition, during operation, sediments such as sand, gravel, and silt can be cleaned, thereby reducing the labor intensity of relevant personnel and improving the filtration efficiency of sewage.
