Description

Technical Field

[0001] The present invention relates to the technical field of water supply and drainage filtration, and specifically relates to a water supply and drainage filtration device that prevents blockage. Background Art

[0002] Water supply and drainage generally refers to the urban water supply system and drainage system (municipal water supply and drainage and building water supply and drainage), simply referred to as water supply and drainage. With the rapid development of society, there is more and more urban sewage. In order to prevent the sewer from being blocked when discharging sewage, people generally equip the sewer with corresponding filtration devices.

[0003] When traditional filtration devices are in use, a fixed filter screen structure is mostly adopted, which makes the filter screen easily covered by sundries quickly, forming a dense blockage layer. If not cleaned in time, it will affect the drainage efficiency, shorten the service life of the filter screen structure, and the maintenance cost and downtime caused by blockage will also be prolonged. Currently, the solutions for preventing blockage of the filter screen mainly include manual regular cleaning and high-pressure water jet cleaning. Manual cleaning has low efficiency and potential safety hazards; the high-pressure water jet cleaning technology impacts the surface of the filter screen through high-pressure water flow. Although it can effectively peel off the attachments and play a certain role in preventing blockage, there are problems such as high energy consumption, strict requirements for water pressure stability, and difficulty in eliminating cleaning blind spots. Moreover, frequent high-pressure impacts are likely to damage the filter screen structure, instead increasing the blockage risk. Summary of the Invention

[0011] Preferably, a pulley group B forming a transmission structure is sleeved on the outer surfaces of the spiral member and the support shaft A. The side of the impurity guiding member away from the impurity discharge port is inclined downward.

[0012] Preferably, a limiting ring B forming a sliding structure with the gear ring B is arranged inside the water supply and drainage pipeline below the filter screen. A rotating shaft connected to the gear disk B is rotatably connected to the mounting plate inside the water supply and drainage pipeline through a bearing. A worm wheel is arranged at the end of the rotating shaft away from the gear disk B. A worm meshed with the front end of the gear disk B is rotatably connected to the water supply and drainage pipeline and the mounting plate through bearings.

[0013] Preferably, a support shaft B is rotatably connected to the mounting block on one side of the water supply and drainage pipeline through a bearing.

[0017] Preferably, a knocking frame is connected between the two supporting members, and the knocking frame includes a swing frame connected to the supporting members and a rubber ball connected to the swing frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention realizes efficient and energy-saving self-cleaning of the filter screen through the synergistic effect of the anti-blocking mechanism, the rotating mechanism and the knocking mechanism, so as to improve the anti-blocking effect of the water supply and drainage filter device; the driving motor in the anti-blocking mechanism drives the support shaft A to drive the roller brush to revolve, and at the same time, the toothed disc A and the gear ring A are engaged to make the roller brush rotate in the opposite direction, thereby forming a dynamic shear force, and efficiently peeling off the debris on the surface of the filter screen; the inclined push plate and the roller brush guide the debris into the guide piece through the centrifugal force, and the spiral piece is combined to discharge it in a directional manner, thereby preventing secondary blockage; the support shaft A in the rotating mechanism is driven by the support shaft A to drive the roller brush to revolve, and the roller brush is driven by the support shaft A ... The support shaft B is linked to the pulley group, driving the worm gear mechanism to make the filter rotate in the opposite direction at a uniform speed. The relative speed of the roller brush and the filter is doubled, further enhancing the stripping effect. At the same time, the centrifugal force throws the loose impurities to the edge of the filter, reducing the risk of clogging in the central area. In addition, the spiral water pipe makes the sewage evenly distributed and filtered, and the support shaft A drives the cam plate to drive the knocking frame to reciprocate, and the torsion spring energy storage release generates high-frequency micro-vibration, which effectively prevents debris from adhering to the wall of the water pipe, improves the water diversion efficiency, and realizes multiple functions through a single drive motor. The energy consumption is greatly reduced compared to high-pressure flushing.

[0019] 1. In the water supply and drainage filtering device, when the driving motor is working, the output end of the driving motor drives the rotating frame and the roller brush to revolve around the filter screen through the support shaft A. Since the toothed disc A is meshed and connected with the gear ring A, the roller brush rotates in the opposite direction to the rotation direction of the support shaft A. The two-way movement forms a dynamic shear force, which can effectively peel off the debris attached to the surface of the filter screen, thereby playing a role in automatic cleaning and anti-clogging of the filter screen. Since the inclined push plate is slidably connected to the water supply and drainage pipeline through the limit sleeve and the limit ring A, the roller brush is rotatably connected to the inclined push plate through the connecting rod and the bearing, so that the inclined push plate revolves around the support shaft A as the axis, so that the debris can be introduced into the debris guide member through the centrifugal force generated by the revolution of the roller brush and the inclined push plate, so that the debris can be discharged through the cooperation of the spiral member and the cylinder, thereby preventing secondary blockage.

[0020] 2. When the support shaft A rotates, since the support shaft B is linked with the support shaft A through the pulley group A, the support shaft B and the bevel gear set rotate together with the support shaft A, and at the same time the worm rotates. Since the worm gear is meshed with the worm, the worm gear, the rotating shaft and the gear disk B rotate together. Since the gear disk B is meshed with the gear ring B, and the gear ring B is slidably connected with the water supply and drainage pipeline through the limit ring B, the gear ring B and the filter screen make a uniform rotation in the direction opposite to the rotation direction of the support shaft A. Through this reverse movement, the relative speed of the contact area between the brush and the filter screen is increased, further strengthening the effect of debris stripping. At the same time, the loose debris is thrown away from the center area of the filter screen by centrifugal force, thereby reducing the risk of blockage in the central area.

[0021] 3. For this water supply and drainage filtering device, the spiral water guide pipe can make the sewage drain more evenly from the top of the filter screen, ensuring the filtering effect of the filter screen on the sewage. At the same time, it can play a role in preventing the filter screen from being blocked to a certain extent. When the support shaft A rotates, the cam plate rotates together. Since the push frame is slidably connected with the support frame, and the knocking frame is elastically connected with the support block through a torsion spring, during the process of the end of the cam plate far from the support shaft A contacting and separating from the push frame, the knocking frame can make a reciprocating deflection around the support member through the cooperation of the push frame and the torsion spring. Thus, the knocking frame can reciprocally knock the water guide pipe and make it generate micro-vibrations, thereby preventing debris from adhering to the surface of the water guide pipe and affecting the water guiding effect, and reducing the manual cleaning frequency. At the same time, the micro-vibrations generate a certain impact on the sewage, so that the flocs or lumps in the sewage can be broken up, avoiding local siltation, and improving the flow uniformity of the sewage in the water guide pipe, thereby optimizing the working efficiency of subsequent treatment.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figure 1 , Figure 3 and Figure 4 , the present invention provides a technical solution: a water supply and drainage filtering device for preventing blockage, including a water supply and drainage pipeline 1, a water inlet 6 and a water outlet 7 are respectively arranged at the front end and one side of the water supply and drainage pipeline 1, and the horizontal line of the water inlet 6 is higher than that of the water outlet 7, and a filter screen 10 is movably connected to the middle part inside the water supply and drainage pipeline 1;

[0035] Refer to Figure 1 , Figure 3 and Figure 4It can be seen that the water inlet 6 and the water outlet 7 of the water supply and drainage pipeline 1 are respectively connected to the required pipelines. During the process of sewage being discharged into the water supply and drainage pipeline 1 through the water inlet 6, the sundries in the sewage are filtered by the filter screen 10, and the filtered sewage is discharged through the water outlet 7.

[0036] Refer to Figures 1-6 and Figure 10 It can be seen that an anti-blocking mechanism 2 in contact with the filter screen 10 is arranged through the inside of the water supply and drainage pipeline 1. The anti-blocking mechanism 2 includes a support shaft A202 connected to the water supply and drainage pipeline 1 through a bearing and a support frame 207 welded to the water supply and drainage pipeline 1. A driving motor 201 connected to the support shaft A202 through a coupling is installed at the top end of the water supply and drainage pipeline 1. One end of the support shaft A202 close to the support frame 207 is connected to a rotating frame 203. A brush roller 206 is connected to the side of the rotating frame 203 away from the support frame 207 through a bearing. A gear disk A205 is connected to the side of the brush roller 206 close to the support frame 207. A gear ring A204 connected to the support frame 207 is meshed and connected to the top end of the gear disk A205. A connecting rod 208 is connected to the side of the brush roller 206 away from the gear disk A205 through a bearing, and the bottom end of the connecting rod 208 is connected to an inclined push plate 209. A limiting ring A211 is arranged in the groove inside the water supply and drainage pipeline 1. A limiting sleeve 210 which forms a sliding structure with the limiting ring A211 is arranged on the side of the inclined push plate 209 away from the connecting rod 208. An annular groove is opened at the bottom end of the support frame 207. The rotating frame 203 includes a diagonal bracing plate and a support rod which forms a sliding structure with the annular groove;

[0037] Refer to Figures 1-6 and Figure 10 It can be seen that when the driving motor 201 works, the output end of the driving motor 201 drives the rotating frame 203 and the brush roller 206 to revolve around the filter screen 10 through the support shaft A202. Since the gear disk A205 is meshed and connected to the gear ring A204, the brush roller 206 generates a rotation in the direction opposite to the rotation direction of the support shaft A202. This two-way movement forms a dynamic shear force, so that the sundries attached to the surface of the filter screen 10 can be effectively peeled off, thus playing an automatic cleaning and anti-blocking role for the filter screen 10. Since the inclined push plate 209 is slidably connected to the water supply and drainage pipeline 1 through the limiting sleeve 210 and the limiting ring A211, and the brush roller 206 is rotationally connected to the inclined push plate 209 through the connecting rod 208 and the bearing, the inclined push plate 209 makes a revolution with the support shaft A202 as the axis, so that the sundries can be guided into the sundry guiding member 504 through the centrifugal force generated by the revolution of the brush roller 206 and the inclined push plate 209, so as to discharge the sundries through the cooperation of the spiral member 502 and the cylinder 503, thus preventing secondary blockage.

[0038] Refer to Figure 1 、 Figure 4 and Figure 7It can be seen that discharge ports 8 are provided at both the front and rear ends of the water supply and drainage pipe 1, and a discharge mechanism 5 is arranged on the outer surface of the water supply and drainage pipe 1. The discharge mechanism 5 includes a debris guide member 504 communicating with the discharge port 8. The side of the debris guide member 504 away from the discharge port 8 is inclined downward. A cylinder 503 connected to the water supply and drainage pipe 1 is connected between the two debris guide members 504. A spiral member 502 is connected to the inside of the cylinder 503 through a bearing. A pulley group B501 constituting a transmission structure is sleeved on the outer surfaces of the spiral member 502 and the support shaft A202. A filter plate 9 is arranged in the through groove of the water supply and drainage pipe 1 near the bottom end of the spiral member 502;

[0039] Refer to Figure 1 、 Figure 4 and Figure 7 It can be seen that since the spiral member 502 and the support shaft A202 are linked by the pulley group B501, the spiral member 502 rotates together with the support shaft A202. Thus, the sundries introduced by the debris guide member 504 can be conveyed upward and discharged through the cooperation of the spiral member 502 and the cylinder 503. Furthermore, secondary blockage can be prevented, and manual operation is not required, greatly reducing the labor intensity of workers.

[0040] Refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 8 It can be seen that a rotating mechanism 3 is arranged at the bottom end of the filter screen 10. The rotating mechanism 3 includes a gear ring B308 movably connected to the water supply and drainage pipe 1 and welded to the filter screen 10. A gear disk B307 is meshed and connected to the inside of the gear ring B308. A limiting ring B309 constituting a sliding structure with the gear ring B308 is arranged below the filter screen 10 on the inner side of the water supply and drainage pipe 1. A rotating shaft 306 connected to the gear disk B307 is rotatably connected to the mounting plate on the inner side of the water supply and drainage pipe 1 through a bearing. A worm gear 305 is arranged at one end of the rotating shaft 306 away from the gear disk B307. A worm 304 rotatably connected to both the water supply and drainage pipe 1 and the mounting plate through bearings is meshed and connected to the front end of the gear disk B307. A support shaft B302 is rotatably connected to the inside of the mounting block on one side of the water supply and drainage pipe 1 through a bearing. A bevel gear set 303 is connected between the support shaft B302 and the worm 304. A pulley group A301 constituting a transmission structure is connected between the support shaft B302 and the support shaft A202;

[0041] Refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 8It can be known that when the support shaft A202 rotates, since the support shaft B302 and the support shaft A202 are linked by the pulley group A301, the support shaft B302 and the bevel gear set 303 rotate together with the support shaft A202, and at the same time, the worm 304 rotates. Since the worm gear 305 is meshed with the worm 304, the worm gear 305, the rotating shaft 306 and the gear disk B307 rotate together. Since the gear disk B307 is meshed with the gear ring B308, and the gear ring B308 is slidably connected with the water supply and drainage pipe 1 through the limit ring B309, the gear ring B308 and the filter screen 10 make a uniform rotation in the direction opposite to the rotation direction of the support shaft A202. Through this reverse movement, the relative speed of the contact area between the rotary brush 206 and the filter screen 10 is increased, further strengthening the effect of debris peeling. At the same time, the loose debris is thrown away from the edge of the filter screen 10 by centrifugal force, thereby reducing the risk of accumulation and blockage in the central area.

[0042] Refer to Figure 1 and Figure 9 It can be known that a water guide pipe 11 communicated with the water inlet 6 is arranged in the installation frame inside the water supply and drainage pipe 1. The water guide pipe 11 includes a spiral pipe with an opening at the bottom end and a rubber pipe connected to the water supply and drainage pipe 1 and communicated with the water inlet 6. The installation frame includes a frame body connected to the water supply and drainage pipe 1 and a rubber pad in contact with the water guide pipe 11.

[0043] Refer to Figure 1 and Figure 9 It can be known that through the spiral water guide pipe 11, the sewage can be discharged more evenly from the top of the filter screen 10, ensuring the filtering effect of the filter screen 10 on the sewage. At the same time, it can play a role in preventing the filter screen 10 from being blocked to a certain extent. Through the rubber pad and the rubber pipe, the micro-vibration of the water guide pipe 11 will not affect the operation of the water supply and drainage filtering device.

[0044] Refer to Figure 1 and Figure 10 It can be known that a knocking mechanism 4 is arranged at one end of the support frame 207. The knocking mechanism 4 includes a cam plate 401 connected to the support shaft A202 and a push frame 402 forming a sliding structure with the support frame 207. Support blocks 403 are symmetrically arranged at the top end of the support frame 207. Support members 405 are rotatably connected inside the support blocks 403. A torsion spring 406 is connected between the support member 405 and the support block 403. A knocking frame 404 is connected between the two support members 405. The knocking frame 404 includes a swing frame connected to the support member 405 and a rubber ball connected to the swing frame.

[0045] Refer to Figure 1 and Figure 10It can be seen that when the support shaft A202 rotates, the cam plate 401 rotates together. Since the push frame 402 is slidably connected to the support frame 207, and the knocking frame 404 and the support block 403 are elastically connected by a torsion spring 406, during the process of the end of the cam plate 401 away from the support shaft A202 contacting and separating from the push frame 402, the knocking frame 404 can make reciprocating deflection with the support member 405 as the axis through the cooperation of the push frame 402 and the torsion spring 406. Thus, the knocking frame 404 can reciprocally knock the water guide pipe 11 to generate micro-vibrations, thereby preventing sundries from adhering to the surface of the water guide pipe 11 and affecting the water conduction effect, reducing the manual cleaning frequency. At the same time, the micro-vibrations generate a certain impact on the sewage, so that the flocs or lumps in the sewage can be dispersed, avoiding local siltation, improving the flow uniformity of the sewage in the water guide pipe 11, and thus optimizing the working efficiency of subsequent treatment.

[0046] Working principle: When using the anti-blocking water supply and drainage filtering device, connect the water inlet 6 and the water outlet 7 of the water supply and drainage pipe 1 to the required pipes respectively. During the process of sewage being discharged into the water supply and drainage pipe 1 through the water inlet 6, the sewage can be discharged more evenly from the top of the filter screen 10 through the spiral water guide pipe 11, so as to ensure the filtering effect when filtering sundries in the sewage through the filter screen 10. The filtered sewage is discharged through the water outlet 7;

[0047] During the process of filtering sewage through the filter screen 10, the filter screen 10 is prone to being blocked. Therefore, it is necessary to start the drive motor 201, so that the output end of the drive motor 201 drives the rotating frame 203 and the rotary brush 206 to revolve around the filter screen 10 through the support shaft A202. Through the meshing action of the gear disk A205 and the gear ring A204, the rotary brush 206 generates a self-rotation in the direction opposite to the rotation direction of the support shaft A202. Through this bidirectional movement, a dynamic shear force is formed, so that the sundries attached to the surface of the filter screen 10 can be effectively peeled off. Through the sliding action of the inclined push plate 209 and the water supply and drainage pipeline 1 and the rotating action of the rotary brush 206 and the inclined push plate 209, the inclined push plate 209 makes a revolution around the support shaft A202 as the axis, so that the sundries can be introduced into the impurity guide member 504 through the centrifugal force generated by the revolution of the rotary brush 206 and the inclined push plate 209 through the impurity discharge port 8. At the same time, through the linkage action of the support shaft B302 and the support shaft A202, the support shaft B302 and the bevel gear set 303 rotate together with the support shaft A202, and at the same time the worm 304 rotates. Through the meshing action of the worm gear 305 and the worm 304, the worm gear 305, the rotating shaft 306 and the gear disk B307 rotate together. Through the meshing action of the gear disk B307 and the gear ring B308 and the sliding action of the gear ring B308 and the water supply and drainage pipeline 1, the gear ring B308 and the filter screen 10 make a uniform rotation in the direction opposite to the rotation direction of the support shaft A202, so as to improve the relative speed of the contact area between the rotary brush 206 and the filter screen 10 through this reverse movement, further strengthening the sundry peeling effect, and throwing the loose sundries away from the edge of the filter screen 10 through the centrifugal force;

[0048] During this process, through the linkage action of the spiral member 502 and the support shaft A202, the spiral member 502 rotates together with the support shaft A202, so that the sundries introduced by the impurity guide member 504 can be discharged through the cooperation of the spiral member 502 and the cylinder body 503. Furthermore, secondary blockage can be prevented, and manual operation is not required, greatly reducing the labor intensity of workers. At the same time, the sewage mixed with sundries in the impurity guide member 504 and the cylinder body 503 enters the water supply and drainage pipeline 1 again after being filtered by the filter plate 9;
