Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment, and more specifically, particularly relates to an energy-saving sewage treatment device. Background Art

[0002] Sewage treatment refers to making sewage meet the water quality requirements for discharging into a certain water body or for reuse. In sewage treatment, a grille is mainly used to remove larger suspended solids and floating objects in sewage, such as branches, plastic garbage, paper, etc. It is composed of a group of parallel metal grille bars. When sewage flows through the grille, larger objects are intercepted in front of the grille bars.

[0003] Chinese Patent Publication No.: CN210595307U, a sewage treatment grille with adjustable clear spacing of grille bars. A plurality of longitudinal grille bars are detachably installed in the longitudinal installation grooves, and a plurality of transverse adjustment grille bars are movably installed in the sliding grooves. At both sides of the top of the grille frame, there are spare fixing frames for storing longitudinal grille bars; this utility model can adjust the clear spacing of grille bars according to needs and has a wide range of applications.

[0004] The existing sewage treatment grilles have the following disadvantages: 1. When the existing sewage grilles are adjusted, most of them need to be adjusted one by one, resulting in low efficiency of grille adjustment, consuming a lot of manpower, and because they are adjusted manually, it is difficult for the adjusted grilles to maintain the consistency of the spacing, and their adaptability is poor; 2. When the existing grilles are actually used, they cannot adjust the angle of the grille according to the actual situation of sewage treatment, resulting in certain limitations in grille treatment. For example, when dealing with intercepted objects later, the intercepted objects accumulate on the grille, which may cause the intercepted objects to be unable to be effectively flushed and collected.

[0005] In view of this, research and improvement are carried out on the existing structure and deficiencies, and an energy-saving sewage treatment device is provided in order to achieve a more practical value. Summary of the Invention

[0008] Preferably, adjusting columns are fixedly installed at the upper ends of each of the intercepting grilles, and each adjusting column is slidably installed through the inner side wall of the transverse chute and slidably installed through the inner side wall of each adjusting inclined chute respectively.

[0009] Preferably, cylindrical connectors are fixedly installed at the upper ends of each of the adjusting columns, worm gears are fixedly installed at the circumferential ends of each of the cylindrical connectors, and each of the worm gears is meshed with each of the driving gears respectively.

[0010] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by providing intercepting grilles with adjustable spacing, the user can adjust the spacing between the intercepting grilles according to the sewage flow rate and the amount of suspended matter. When encountering sewage containing a large amount of large debris, the spacing between the intercepting grilles can be increased to avoid the intercepting grilles being blocked too quickly and ensure that the sewage can pass through smoothly. When the debris in the sewage is small, the spacing between the intercepting grilles can be reduced to improve the interception effect on fine suspended matter. For changes in water volume, when the sewage flow rate is large, appropriately increasing the spacing between the intercepting grilles can reduce the water flow resistance and prevent sewage overflow; when the flow rate is small, reducing the spacing between the intercepting grilles can better filter the sewage, so as to adapt to the sewage interception and treatment in different situations.

[0011] In the present invention, by providing the cooperation of the adjusting plate, the adjusting inclined chute and the adjusting column, when adjusting the intercepting grilles, it is not necessary to adjust them one by one. By rotating the handle on one side forward or reversely, the adjusting plate can be driven to move, so as to realize the synchronous adjustment of the distances between multiple intercepting grilles at the same time, and the adjustment of the spacing of all intercepting grilles can be completed in a short time, improving the working efficiency of the adjustment, and ensuring the consistency of the spacing between the intercepting grilles. If the spacing between the intercepting grilles is inconsistent, it will affect the interception effect on suspended matter.

[0012] In the present invention, by providing intercepting grilles with adjustable angles, when the angles of the intercepting grilles can be adjusted according to the sewage conditions, during the later treatment and flushing of the suspended matter intercepted by the intercepting grilles, the suspended matter in the sewage can slide down more under the dual action of gravity and water flow for collection and treatment, preventing the situation that debris accumulates on the surface of the intercepting grilles and is not easy to handle. The intercepting grilles with adjustable angles are more convenient for the subsequent cleaning and treatment of the intercepted debris, and avoid the situation of blockage in the later treatment.

[0013] In the present invention, by providing a form in which a plurality of worm gears and worm wheels are matched, when adjusting the angle of each intercepting grille, it is not necessary to adjust them one by one. By rotating the pull rod, each worm gear can be driven to rotate simultaneously, so that each intercepting grille rotates and adjusts simultaneously. While ensuring convenient adjustment, the consistency of the angles of each intercepting grille after adjustment is guaranteed.

[0014] In the present invention, by providing a cooperation of a pull rod, a limiting rod and a limiting groove, after the angle of the intercepting grille is adjusted, the limiting rod on the pull rod can be inserted and fixed on the inner side wall of the limiting groove by the spring reset and rebound. After adjustment, each worm gear can be limited to avoid the situation that the intercepting grille shakes unstably under the action of water flow scouring, and its stability is good.

[0015] In the present invention, by providing a cooperation of a telescopic connecting piece and a worm gear, when each worm gear moves closer to or away from each other, each movable rod can be driven to slide in the movable tube, so that each worm gear can move along with the worm wheel, ensuring the meshing effect between each worm gear and the worm wheel. Thus, while ensuring that the fire extinguishing intercepting grille can adjust the spacing, it can also adjust the angle, making the use of the intercepting grille more flexible and having higher adaptability during use.

The two transmission shafts 6 are respectively rotatably installed on the inner side walls of the two supporting grooves 31. The upper end of the adjustment plate 7 is provided with a plurality of adjustment inclined grooves 71. Each adjustment inclined groove 71 is symmetrically distributed with the center line of the adjustment plate 7 as the axis of symmetry. The adjustment inclined grooves 71 on both sides are inclined. The user can rotate the handle 75 on one side forward or backward. The rotation of the handle 75 on one side will drive the rotating column 73 to rotate. The rotation of the rotating column 73 on one side will drive the transmission gear 74 to rotate. The rotation of the transmission gear 74 on one side will drive the transmission gear 74 on the other side to rotate simultaneously through the toothed belt 77, thereby realizing the simultaneous rotation of the rotating columns 73 on both sides. The simultaneous rotation of the rotating columns 73 on both sides will drive the lead screws 76 on both sides to rotate simultaneously. The rotation of the lead screws 76 on both sides will drive the adjustment plate 7 to slide in the horizontal direction through the two thread grooves 72. A plurality of adjustment inclined grooves 71 are provided on the adjustment plate 7. When the adjustment plate 7 moves toward the side close to the pretreatment tank 1, it will drive the adjustment column 83 to move and slide in the adjustment inclined grooves 71 and approach each other; The bearing plate 8 is located at the lower end of the adjusting plate 7. The bearing plate 8 is slidably installed on the inner side wall of the pretreatment tank 1. A transverse chute 81 is formed through the upper end of the bearing plate 8. The protective shell 9 is fixedly installed at the side ends of the two C-shaped frames 24. An operation slot 91 is formed through the side end of the protective shell 9. Rear guide plates 14 are fixedly installed at both side ends of the inner side wall of the interception tank 11. The two side ends of the guide plate 14 are both beveled surfaces. At least two slots 13 are formed through the upper end of the pretreatment tank 1. The end of the inner side wall of each slot 13 is made of metal. There are multiple processes in sewage treatment. In the previous stage of sewage collection and treatment, larger suspended solids and floating objects in the sewage, such as branches, plastic garbage, paper, etc., need to be treated before subsequent fine treatment can be carried out. When treating the suspended solids and floating objects in the sewage, generally, an interception grid 82 is set for interception treatment. The user can introduce the sewage into the pretreatment tank 1. For the existing sewage drainage to achieve energy-saving treatment, solar energy is mostly used as the driving power and is used in conjunction with a water pump. After the sewage flows through the interception tank 11, it enters the post-treatment tank 12, and its suspended solids and floating objects will be intercepted by the interception grid 82 in the interception tank 11; An installation insertion rod 22 is fixedly installed at the lower end of each installation block 2. A circular magnet 23 is fixedly installed at the lower end of each installation insertion rod 22. Each installation insertion rod 22 is respectively slidably installed on the inner side wall of the slot 13. Each circular magnet 23 is respectively adsorbed to the end of the inner side wall of the slot 13. A plurality of limiting slots 32 are arranged in an array at the side end of the supporting plate 3. The worm gears 4 on both sides and the two transmission shafts 6 are fixedly connected through a telescopic connecting member 5. The telescopic connecting member 5 is integrated with a movable rod 51 and a movable tube 53. The movable rod 51 is slidably installed on the inner side wall of the movable tube 53. An activity guide rail 54 is formed through the circumferential end of the movable tube 53. An activity guide block 52 is fixedly installed at the circumferential end of the movable rod 51. The activity guide block 52 is slidably installed on the inner side wall of the activity guide rail 54. When adjusting the distance between each interception grid 82, when each interception grid 82 moves, it will drive each columnar connecting member 84 to move through the adjusting column 83. When each columnar connecting member 84 moves, it will drive each worm gear 4 to move through the worm wheel 85. A telescopic connecting member 5 is fixedly installed between every two worm gears 4. When each worm gear 4 moves closer to or away from each other, it will drive each movable rod 51 to slide in the movable tube 53, so that each worm gear 4 can move following the worm wheel 85, ensuring the meshing effect between each worm gear 4 and the worm wheel 85; Limit discs 61 are fixedly installed at the circumferential ends of both transmission shafts 6. A pull rod 62 is also provided on one side of the transmission shaft 6. A spring 63 and a telescopic rod 64 are fixedly installed between the pull rod 62 and the transmission shaft 6. The telescopic rod 64 is located on the inner side wall of the spring 63. A limit rod 65 is fixedly installed at the side end of the pull rod 62. The limit rod 65 is slidably installed on the inner side wall of the limit groove 32. When the distance between the interception gratings 82 can be adjusted, the user can also adjust the angle of each interception grating 82 according to the interception requirements. The user can pull the pull rod 62. The pull rod 62 moves to stretch the spring 63 and the telescopic rod 64. The movement of the pull rod 62 will pull the limit rod 65. After the limit rod 65 moves away from the inner side wall of the limit groove 32, the user can rotate the pull rod 62. The rotation of the pull rod 62 drives the transmission shaft 6 to rotate. The rotation of the transmission shaft 6 drives each worm 4 to rotate through the telescopic connecting member 5. The rotation of each worm 4 drives each worm gear 85 to rotate. The rotation of each worm gear 85 drives each adjusting column 83 to rotate through the cylindrical connecting member 84. The rotation of each adjusting column 83 drives each interception grating 82 to rotate. After each interception grating 82 is rotated to a suitable angle, the user can stop rotating the pull rod 62. The user can insert the limit rod 65 on the pull rod 62 into the inner side wall of the limit groove 32 again to limit each worm 4 and complete the adjustment of the angle of the interception grating 82; Two wire grooves 72 are penetrated and provided at the side end of the adjusting plate 7. Two screw rods 76 are rotatably installed on the inner side walls of the two wire grooves 72 by threads. Rotating columns 73 are fixedly installed at both side ends of the two screw rods 76. Each rotating column 73 is respectively rotatably installed on the inner side wall of the installation circular groove 21. Handle 75 is fixedly installed at the side end of each rotating column 73. Transmission gears 74 are fixedly installed at the circumferential ends of the two rotating columns 73. The circumferential ends of the two transmission gears 74 are both meshed and sleeved with the same toothed belt 77. Adjusting columns 83 are fixedly installed at the upper ends of each intercepting grille 82. Each adjusting column 83 is slidably installed through the inner side wall of the transverse sliding groove 81. Each adjusting column 83 is respectively slidably installed through the inner side wall of each adjusting inclined groove 71. Column-shaped connectors 84 are fixedly installed at the upper ends of each adjusting column 83. Worms 85 are fixedly installed at the circumferential ends of each column-shaped connector 84. Each worm 85 is respectively meshed with each transmission gear 74. Each adjusting column 83 is restricted within the transverse sliding groove 81. Therefore, each adjusting column 83 will only slide within the transverse sliding groove 81 when moving. The sliding of each adjusting column 83 will drive each intercepting grille 82 to slide closer to each other. When the adjusting plate 7 slides towards the side of the post-treatment tank 12, the distance between each intercepting grille 82 will be away from each other at this time, so as to realize the adjustment of the distance between each intercepting grille 82. During the sewage treatment process, the water quality and water volume of the sewage will change. During the rainy season, the combined sewage of rain and sewage may contain more large floating objects such as leaves and branches; during the dry season, the suspended solids in the sewage may be relatively small and the quantity is small. When encountering sewage containing a large amount of large debris, the distance between the intercepting grilles 82 can be increased to avoid the intercepting grilles 82 being blocked too quickly and ensure that the sewage can pass through smoothly. In the case of small debris in the sewage, the distance between the intercepting grilles 82 can be reduced to improve the interception effect on fine suspended solids.

[0020] Working principle: First step, there are multiple processes in sewage treatment. In the previous stage of sewage collection and treatment, larger suspended solids and floating objects in the sewage, such as branches, plastic garbage, paper, etc., need to be treated before subsequent fine treatment can be carried out. When treating the suspended solids and floating objects in the sewage, generally, intercepting grilles 82 are set for interception treatment. The user can introduce the sewage into the pre-treatment tank 1. For the existing sewage diversion to achieve energy-saving treatment, solar energy is mostly used as the driving power and used in cooperation with a water pump. After the sewage flows through the interception tank 11, it enters the post-treatment tank 12, and its suspended solids and floating objects will be intercepted by the intercepting grilles 82 in the interception tank 11; Step 2: When intercepting suspended solids and floating substances in sewage, the user can adjust the spacing between each intercepting grid 82 according to factors such as sewage flow rate, the quantity of suspended solids and floating substances. The user can rotate the handle 75 on one side in the forward or reverse direction. The rotation of the handle 75 on one side drives the rotation column 73 to rotate. The rotation of the rotation column 73 on one side drives the transmission gear 74 to rotate. The rotation of the transmission gear 74 on one side drives the transmission gear 74 on the other side to rotate simultaneously through the toothed belt 77, thereby realizing the simultaneous rotation of the rotation columns 73 on both sides. The simultaneous rotation of the rotation columns 73 on both sides drives the screw rods 76 on both sides to rotate simultaneously. The rotation of the screw rods 76 on both sides drives the adjusting plate 7 to slide in the horizontal direction through the two screw grooves 72. A plurality of adjusting inclined grooves 71 are formed on the adjusting plate 7. When the adjusting plate 7 moves towards the side close to the pretreatment tank 1, it drives the adjusting column 83 to move and slide in the adjusting inclined groove 71 and approach each other. Since each adjusting column 83 is restricted in the transverse sliding groove 81, each adjusting column 83 will only slide in the transverse sliding groove 81 when moving. The sliding of each adjusting column 83 drives each intercepting grid 82 to slide and approach each other. When the adjusting plate 7 slides towards the side of the post-treatment tank 12, the distance between each intercepting grid 82 will move away from each other, thereby realizing the adjustment of the spacing between each intercepting grid 82. During the sewage treatment process, the water quality and quantity of sewage will change. During the rainy season, the combined sewage of rain and sewage may contain more large floating substances such as leaves and branches. During the dry season, the suspended solids in the sewage may be relatively small and the quantity may be small. When encountering sewage containing a large amount of large debris, the spacing of the intercepting grid 82 can be increased to avoid the intercepting grid 82 being blocked too quickly and ensure that the sewage can pass smoothly. When the debris in the sewage is small, the spacing of the intercepting grid 82 can be reduced to improve the interception effect on fine suspended solids. For the change in water quantity, when the sewage flow rate is large, appropriately increasing the spacing of the intercepting grid 82 can reduce the water flow resistance and prevent sewage overflow. When the flow rate is small, reducing the spacing of the intercepting grid 82 can better filter the sewage; Two guide plates 14 are fixedly installed at both end parts of the inner side wall of the intercepting tank 11. The end part of the guide plate 14 is an inclined section, which can guide the sewage flow to the position of the intercepting grid 82 and can prevent the intercepting grids 82 on both sides from moving closer. When the gap between the intercepting grids 82 on both sides and the inner side wall of the intercepting tank 11 is too large, it may cause the failure of suspended solid interception; This device is equipped with an interception grid 82 with adjustable spacing. Users can adjust the spacing between the interception grids 82 according to the sewage flow rate and the amount of suspended solids. When encountering sewage containing a large amount of large debris, the spacing between the interception grids 82 can be increased to avoid rapid blockage of the interception grids 82 and ensure the smooth passage of sewage. When the debris in the sewage is small, the spacing between the interception grids 82 can be reduced to improve the interception effect on fine suspended solids. For changes in water volume, when the sewage flow rate is large, appropriately increasing the spacing between the interception grids 82 can reduce the water flow resistance and prevent sewage overflow; when the flow rate is small, reducing the spacing between the interception grids 82 can better filter the sewage, so as to adapt to the sewage interception and treatment in different situations; This device is provided with a cooperation of a regulating plate 7, a regulating chute 71 and a regulating column 83. When adjusting the interception grid 82, it is not necessary to adjust each one individually. By rotating the handle 75 on one side forward or backward, the regulating plate 7 can be driven to move, thereby realizing the synchronous adjustment of the distances of multiple interception grids 82 at the same time. The adjustment of the spacing of all the interception grids 82 can be completed in a short time, improving the working efficiency of the adjustment, and ensuring the consistency of the spacing of the interception grids 82. If the spacing of the interception grids 82 is inconsistent, it will affect the interception effect on suspended solids; In the third step, when the spacing between the interception grids 82 can be adjusted, the user can also adjust the angle of each interception grid 82 according to the interception requirements. The user can pull the pull rod 62, and the pull rod 62 moves to stretch the spring 63 and the telescopic rod 64. When the pull rod 62 moves, it will pull the limit rod 65. After the limit rod 65 moves away from the inner wall of the limit groove 32, the user can rotate the pull rod 62. The rotation of the pull rod 62 drives the transmission shaft 6 to rotate. The rotation of the transmission shaft 6 drives each worm 4 to rotate through the telescopic connecting piece 5. The rotation of each worm 4 drives each worm gear 85 to rotate. The rotation of each worm gear 85 drives each regulating column 83 to rotate through the cylindrical connecting piece 84. The rotation of each regulating column 83 drives each interception grid 82 to rotate. After rotating each interception grid 82 to an appropriate angle, the user can stop rotating the pull rod 62. The user can insert the limit rod 65 on the pull rod 62 into the inner wall of the limit groove 32 again to realize the limit of each worm 4 and complete the adjustment of the angle of the interception grid 82; This device is provided with an interception grid 82 with adjustable angle. When the angle of the interception grid 82 can be adjusted according to the sewage situation, during the later treatment and flushing of the suspended solids intercepted by the interception grid 82, the suspended solids in the sewage can slide down under the dual action of gravity and water flow for collection and treatment, preventing the situation where debris accumulates on the surface of the interception grid 82 and is not easy to handle. The interception grid 82 with adjustable angle is more convenient for the subsequent cleaning and treatment of intercepted debris, avoiding the situation of blockage in later treatment; By arranging a plurality of worm gears 4 and worm wheels 85 in cooperation, when adjusting the angle of each intercepting grille 82, it is not necessary to adjust them one by one. By rotating the pull rod 62, each worm gear 4 can be driven to rotate simultaneously, so that each intercepting grille 82 rotates and adjusts simultaneously. While ensuring convenient adjustment, the consistency of the angles of each intercepting grille 82 after adjustment is guaranteed; By arranging the cooperation of the pull rod 62, the limiting rod 65 and the limiting groove 32, after the angle of the intercepting grille 82 is adjusted, the limiting rod 65 on the pull rod 62 can be driven by the spring 63 to reset and rebound and be inserted and fixed on the inner side wall of the limiting groove 32. After adjustment, each worm gear 4 can be ensured to be limited, avoiding the unstable situation that the intercepting grille 82 shakes under the force of water flow scouring, and its stability is better; Fifth step, when adjusting the distance between each intercepting grille 82, when each intercepting grille 82 moves, it will drive each cylindrical connecting piece 84 to move through the adjusting column 83. When each cylindrical connecting piece 84 moves, it will drive each worm gear 4 to move through the worm wheel 85. A telescopic connecting piece 5 is fixedly installed between every two worm gears 4. When each worm gear 4 moves closer to or away from each other, it will drive each movable rod 51 to slide in the movable tube 53, so that each worm gear 4 can move along with the worm wheel 85, ensuring the meshing effect between each worm gear 4 and the worm wheel 85; By arranging the cooperation of the telescopic connecting piece 5 and the worm gear 4, when each worm gear 4 moves closer to or away from each other, it will drive each movable rod 51 to slide in the movable tube 53, so that each worm gear 4 can move along with the worm wheel 85, ensuring the meshing effect between each worm gear 4 and the worm wheel 85. Furthermore, while ensuring that the fire extinguishing intercepting grille 82 can be adjusted in distance, it can also be adjusted in angle, making the use of the intercepting grille 82 more flexible and the adaptability during use higher.
