Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to sewage treatment equipment for municipal roads. Background Art

[0002] In municipal road projects, rainwater or sewage is transported through rainwater and sewage pipes. In order to ensure the smooth flow of the pipes, filtering devices are usually installed inside each rainwater and sewage well or near the water inlet to filter out impurities in the water.

[0003] During the drainage process of the auxiliary pipes of municipal roads, more impurities will gradually accumulate inside the pipes, rainwater and sewage wells or filtration devices, causing partial blockage of the drainage system. When there is a lot of rainwater and sewage in the pipes, problems such as poor drainage and urban waterlogging will occur. In order to ensure the drainage effect, it is necessary to clean the impurities in the drainage system regularly.

[0004] The existing technology mainly uses high-pressure water to flush the impurities attached to the inner wall to remove the impurities on the inner wall surface, but the flushing efficiency is low and a large amount of water will be wasted. At the same time, the impurities will still flow along the pipeline and gradually attach to the subsequent pipeline, affecting the drainage effect inside the pipeline. Therefore, a municipal road sewage treatment equipment is designed to clean the impurities attached to the inner wall of the drainage system to avoid more impurities remaining in the drainage system and affecting the drainage efficiency.

However, the present invention can be implemented in various forms, so the present invention is not limited to the embodiments described below. In addition, in order to more clearly describe the present invention, components that are not connected with the invention will be omitted from the drawings.

[0040] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0041] Embodiment 1:

[0042] This embodiment introduces a specific structure of a municipal road sewage treatment equipment. Figure 1-Figure 15As shown, it includes a box body 1, a treatment barrel 2 is installed inside the box body 1 and near the top, a sedimentation box 23 is arranged below the treatment barrel 2, a filter barrel 3 is arranged inside the treatment barrel 2, a water inlet pipe 11 is arranged on the right side wall of the box body 1 and near the center of the filter barrel 3, a submersible pump 4 is connected to the left side of the water inlet pipe 11, a crushing mechanism is arranged at the bottom of the submersible pump 4, the crushing mechanism is coaxially connected to the impeller drive shaft of the submersible pump 4, a supporting mechanism is arranged on the outside of the pump body of the submersible pump 4, the supporting mechanism includes a fixed sleeve 5, a sliding sleeve 51 and a supporting block 52, a strip-shaped sewage outlet 31 is arranged at the bottom end of the filter barrel 3, a conveying trough 32 is arranged below the sewage outlet 31, a number of evenly distributed micro-filter holes are opened on the filter barrel 3 and the conveying trough 32, a flipping frame 6 is arranged on the inner side of the filter barrel 3, a ring-shaped array distributed flipping mechanism is arranged on the flipping frame 6, and the flipping mechanism includes an arc plate 61, a Y-shaped plate 64 and a guide plate 65.

[0043] The equipment is mainly used for cleaning impurities inside drainage pipes, rainwater and sewage wells or filtering devices. When in use, the submersible pump 4 is moved to the inside of the drainage pipes, rainwater and sewage wells or filtering devices, and the fixing sleeve 5, the sliding sleeve 51 and the supporting block 52 cooperate with each other to support and fix the submersible pump 4. After that, the submersible pump 4 is operated to extract sewage, and drives the crushing mechanism to rotate synchronously, so that the crushing mechanism crushes larger impurities in the sewage and improves the mixing effect of sewage and sludge, so that the submersible pump 4 transports sewage mixed with a large amount of sludge or impurities to the inside of the filter barrel 3 for treatment, and the micro-filter holes on the filter barrel 3 and the conveying trough 32 filter the sewage, so that the sludge gradually falls into the conveying trough 32 for outward transportation, and the sewage falls into the sedimentation box 23 and is discharged after sedimentation.

[0044] When the sludge mixed with sewage falls into the filter barrel 3, the arc plate 61, the Y-shaped plate 64 and the guide plate 65 cooperate with each other to continuously turn over and guide the sludge in the filter barrel 3, thereby improving the filtering and separation effect of sewage and sludge.

[0045] like Figure 2 and Figure 8 As shown, the water inlet pipe 11 and the filter barrel 3 are located on the same center line, and a water distributor 12 is welded and fixed at the right end of the water inlet pipe 11 and located on the inner side of the turning frame 6. The water distributor 12 is a hollow structure in the shape of a triangular prism, and the top of the water distributor 12 is a symmetrically distributed inclined structure. The inclined design has a guiding effect on sewage and sludge. During the process of turning the sludge, the turning mechanism can prevent the sludge from accumulating on the top of the water distributor 12. A plurality of water distribution frames 121 staggered front and back are provided at the bottom of the water distributor 12, so that the bottom of the water distributor 12 forms water distribution holes staggered front and back, and has a guiding effect on the water body inside the water distributor 12, so that the sewage is evenly distributed inside the filter barrel 3. A support rod 122 is welded and fixed on the right side of the water distributor 12.

[0046] like Figure 1 , Figure 4-Figure 6 As shown, a hose 41 is connected to the top of the submersible pump 4, and the other end of the hose 41 is fixedly connected to the water inlet pipe 11 through a flange. A pump seat 42 is arranged at the bottom of the submersible pump 4, and the crushing mechanism includes a stirring frame 43, and the stirring frame 43 is arranged below the pump seat 42. A connecting ring 431 is arranged on the top of the stirring frame 43, and the connecting ring 431 is rotatably connected to the outer wall of the pump seat 42, which can improve the stability of the stirring frame 43 during rotation. Blades 44 distributed in an annular array are installed on the inner side of the stirring frame 43 and near the bottom end, and cleaning brushes 45 distributed in an annular array are installed on the outer wall of the stirring frame 43. A coupling 46 is arranged above the stirring frame 43 and near the center, and the rotating shaft of the stirring frame 43 is coaxially connected with the impeller drive shaft of the submersible pump 4 through the coupling 46.

[0047] When the impeller of the submersible pump 4 rotates to transport the water, the impeller drive shaft of the submersible pump 4 can drive the stirring frame 43 to rotate at the bottom of the submersible pump 4 through the coupling 46, so that the stirring frame 43 continuously stirs the sewage, thereby improving the mixing effect of the sewage and the sludge, and facilitating the submersible pump 4 to transport the sludge mixed with sewage. At the same time, the blade 44 arranged at the bottom end of the stirring frame 43 can crush the sludge or larger impurities to prevent the blockage of the submersible pump 4 caused by the lumpy sludge or larger impurities, and the cleaning brush 45 on the outside of the stirring frame 43 can brush up the sludge on the inner wall surface of the drainage pipe, the rainwater and sewage well or the filter device, thereby improving the cleaning efficiency and facilitating sewage treatment.

[0048] A storage chamber 15 is provided inside the box body 1 and on the left side of the sedimentation box 23. A movable door 151 is installed on the left outer wall of the storage chamber 15. The movable door 151 is connected to the outer wall of the box body 1 through a hinge. When sewage treatment is not performed, the movable door 151 is opened, and the submersible pump 4, the fixed sleeve 5 and the supporting mechanism can be stored through the storage chamber 15.

[0049] The fixing sleeve 5 is arranged on the outside of the submersible pump 4 and is fixedly connected to the outer wall of the pump body of the submersible pump 4. Two groups of sliding sleeves 51 are symmetrically arranged on the fixing sleeve 5 and are slidably connected to the fixing sleeve 5. An integrally formed limiting ridge 511 is arranged on the outer wall of the fixing sleeve 5. The limiting ridge 511 limits the sliding sleeve 51 to prevent the sliding sleeve 51 from rotating. Three groups of supporting blocks 52 are arranged on the outside of the fixing sleeve 5 in a ring array. An adjusting plate 53 symmetrically distributed up and down is rotatably connected on the supporting block 52 and close to the side of the fixing sleeve 5. The other end of the adjusting plate 53 is rotatably connected to the sliding sleeve 51. A rubber pad 521 is bonded and fixed on the side of the supporting block 52 away from the fixing sleeve 5. When the upper and lower groups of sliding sleeves 51 slide along the fixing sleeve 5 at the same time, the supporting block 52 can be driven to move outward by the adjusting plate 53, so that the rubber pad 521 is in close contact with the inner wall of the drainage pipe, rainwater and sewage well or filtering device, thereby supporting and fixing the submersible pump 4, improving the stability of the submersible pump 4 and the crushing mechanism during rotation, and facilitating the treatment of sewage.

[0050] A mounting base 54 is welded and fixed to the bottom of the fixed sleeve 5, and the bottom of the mounting base 54 is fixedly connected to the top of the pump seat 42. A rotatable bidirectional screw 55 is provided on the fixed sleeve 5 near the right edge, and the threaded sections of the bidirectional screw 55 are respectively threadedly connected to the upper and lower driving sleeves 51. A motor 56 is installed inside the mounting base 54 and below the bidirectional screw 55. The output shaft of the motor 56 is coaxially driven with the bidirectional screw 55. A protective sleeve 57 is installed on the fixed sleeve 5 near the outer edge. The protective sleeve 57 plays a protective role at the edge of the fixed sleeve 5 to reduce the wear of the bidirectional screw 55.

[0051] When the motor 56 runs and drives the bidirectional screw 55 to rotate, the two ends of the bidirectional screw 55 move relative to the upper and lower sets of sliding sleeves 51 respectively, so that the two sets of sliding sleeves 51 slide along the fixed sleeve 5 at the same time, and drive the adjustment plate 53 to rotate, so that the upper and lower adjustment plates 53 cooperate with each other, drive the support block 52 to extend outward, and make the rubber pad 521 in close contact with the inner wall of the drainage pipe, rainwater and sewage well or filtering device, thereby achieving a good fixing effect.

[0052] like Figure 7 , Figure 9-12As shown, an integrally formed collecting hopper 21 is provided at the bottom center of the processing barrel 2, a sedimentation pipe 22 is provided at the bottom of the collecting hopper 21 and located on the inner side of the sedimentation box 23, the sedimentation pipe 22 extends to the bottom end of the sedimentation box 23, a diffusion cover 221 is installed at the bottom of the sedimentation pipe 22, two groups of parallelly distributed first partitions 24 are installed on the inner wall of the sedimentation box 23 and located above the diffusion cover 221, a second partition 25 is provided between the upper and lower groups of first partitions 24, the second partition 25 is welded and fixed to the outer wall of the sedimentation pipe 22, a water outlet pipe 231 is provided on the front side of the sedimentation box 23 and near the top, a sewage pipe 232 is provided on the front side of the sedimentation box 23 and near the bottom, and a control valve is installed on the sewage pipe 232.

[0053] During the treatment process, the sewage filtered by the micro-filter holes on the filter barrel 3 and the conveying trough 32 falls into the collecting bucket 21, and flows to the bottom of the sedimentation box 23 through the sedimentation pipe 22. The diffusion cover 221, the first partition 24 and the second partition 25 cooperate with each other to block and guide the sewage, so that the sewage flows slowly upward, and the suspended matter remaining in the sewage is precipitated at the bottom of the sedimentation box 23. At the same time, the diffusion cover 221, the first partition 24 and the second partition 25 all adopt a slope structure, which can enhance the guiding effect on sewage and sludge, and facilitate the sedimentation of sludge at the bottom of the sedimentation box 23. Afterwards, the treated sewage can be returned to the drainage pipe and the rainwater and sewage well through the outlet pipe 231, and the control valve on the sewage pipe 232 can be opened to discharge the sediment inside the sedimentation box 23.

[0054] The arc plate 61 is arranged in a circular array on the flip frame 6, and the outer surface of the arc plate 61 is in contact with the inner surface of the filter barrel 3. The arc plate 61 is a crescent-shaped arc structure, which can quickly scrape up the sludge on the inner surface of the filter barrel 3 to improve the driving effect on the sludge. A strip opening 62 is arranged between adjacent arc plates 61. When the strip opening 62 is aligned with the sewage outlet 31, the sludge on the arc plate 61 can fall into the conveying trough 32. A filter plate 63 is arranged on the arc plate 61 and near the center. The filter plate 63 can cooperate with the filter barrel 3 to enhance the filtering and separation effect of sewage. The Y-shaped plate 64 is arranged on the center line of the arc plate 61 and is welded and fixed to the inner wall of the arc plate 61. A plurality of guide plates 65 are staggered on both sides of the arc plate 61 and are welded and fixed to the inner wall of the arc plate 61.

[0055] When the arc plate 61 rotates along the inner surface of the filter barrel 3, the Y-shaped plate 64 and the guide plate 65 cooperate with each other to facilitate the sludge to be turned over and block the sludge, thereby enhancing the filtering effect of the filter plate 63 on the sludge. In addition, when the arc plate 61 rotates to just above the sewage outlet 31, the Y-shaped plate 64 guides the sludge to prevent the sludge from falling vertically into the sewage outlet 31, thereby fully filtering part of the sludge and enhancing the separation effect of sludge and sewage.

[0056] A driving frame 66 is welded and fixed to the right side of the turning frame 6, and the driving frame 66 is rotatably connected to the right side wall of the box body 1 through a rotating shaft. A second motor 661 coaxially transmitted with the driving frame 66 is installed on the right side wall of the box body 1. When the second motor 661 is running, it can drive the turning frame 6 to rotate, so that the turning frame 6 drives the arc plate 61 to rotate. Through the cooperation of the arc plate 61, the Y-shaped plate 64 and the guide plate 65, the sludge can be continuously turned over on the inner side of the filter barrel 3, thereby increasing the effective filtration time of the sludge and enhancing the sewage treatment effect.

[0057] A support sleeve 662 is provided on the left side of the driving frame 66 and on the outside of the support rod 122 . The support sleeve 662 is rotatably connected to the end of the support rod 122 , and can support the other side of the water distributor 12 to improve the stability of the water distributor 12 .

[0058] Bearing rings 67 are installed on both sides of the flip frame 6. The bearing rings 67 are fixedly connected to the inner wall of the box body 1. The bearing rings 67 can reduce the friction force when the flip frame 6 rotates, thereby improving the stability of the flip frame 6.

[0059] A spiral conveying blade 33 is provided inside the conveying trough 32, and the rotating shaft of the spiral conveying blade 33 is rotatably connected to the left side wall of the box body 1. A first motor 34 that drives the spiral conveying blade 33 to rotate is installed on the left side wall of the box body 1. A compression chamber 13 is welded and fixed on the right side of the box body 1, and an obliquely distributed discharge rack 14 is provided inside the compression chamber 13 and near the bottom. When the sludge falls into the conveying trough 32, the first motor 34 is turned on to drive the spiral conveying blade 33 to rotate, so that the sludge can be continuously conveyed to the right, so that the sludge is conveyed to the inside of the compression chamber 13 and discharged outward through the discharge rack 14.

[0060] Working principle: This equipment is mainly used for cleaning impurities inside drainage pipes, rainwater and sewage wells or filtering devices. When in use, the submersible pump 4 is moved to the inside of the drainage pipes, rainwater and sewage wells or filtering devices, and then the motor 56 is operated to drive the bidirectional screw 55 to rotate, and drive the two sets of sliding sleeves 51 to slide along the fixed sleeve 5 at the same time, so that the adjustment plate 53 drives the support block 52 to extend outward, thereby fixing the submersible pump 4;

[0061] Furthermore, the submersible pump 4 is operated to transport sewage. During the transport process, the impeller drive shaft of the submersible pump 4 drives the stirring frame 43 to rotate through the coupling 46, so that the stirring frame 43 continuously stirs the sewage. At the same time, the stirring frame 43 drives the blade 44 and the cleaning brush 45 to rotate, so that the blade 44 breaks up the block sludge or larger impurities, and the cleaning brush 45 repeatedly brushes up the sludge, thereby improving the mixing effect of sewage and sludge, and facilitating sewage treatment;

[0062] Furthermore, the turbid sewage flows into the water distributor 12 through the water inlet pipe 11, and evenly falls into the inner side of the filter barrel 3 through the water distribution frame 121, and the filter barrel 3, the filter plate 63 and the conveying trough 32 cooperate with each other to filter and separate the sewage and the sludge. At the same time, the second motor 661 drives the turning frame 6 to rotate, and the arc plate 61, the Y-shaped plate 64 and the guide plate 65 cooperate with each other to continuously turn and guide the sludge, so as to fully filter the sludge and enhance the separation effect of the sludge and sewage.

[0063] Finally, the separated sewage flows to the interior of the sedimentation box 23 through the collecting hopper 21 and the sedimentation pipe 22. After being blocked and guided by the diffusion cover 221, the first baffle 24 and the second baffle 25, the residual suspended matter settles in the sedimentation box 23, and the sewage flows back to the drainage pipe and the rainwater and sewage well through the outlet pipe 231. When the strip opening 62 is aligned with the sewage outlet 31, the sludge falls into the conveying trough 32, so that the first motor 34 drives the spiral conveying blade 33 to rotate continuously, so that the sludge can be conveyed to the interior of the compression chamber 13 and discharged to the outside through the discharge rack 14.

[0064] Embodiment 2:

[0065] This embodiment is an improvement based on the first embodiment:

[0066] like Figure 2 , Figure 12-Figure 15 As shown, in order to facilitate the transportation of the separated sludge and further separate the water in the sludge, a compression barrel 7 is arranged on the right side of the conveying trough 32, and a compression mechanism is arranged inside the compression barrel 7 near the right end, and the compression mechanism includes a squeeze disc 8 and a control seat 81.

[0067] The compression barrel 7 is arranged on the right side of the conveying trough 32 and is welded and fixed to the right inner wall of the compression chamber 13. A connecting sleeve 71 connected to the conveying trough 32 is provided on the left side of the compression barrel 7. A discharge port 72 is provided at the bottom of the compression barrel 7 near the right end. A limiting block 73 is welded and fixed on the top inner wall of the compression barrel 7 near the left end. A spiral extrusion leaf 74 is provided on the left side of the limiting block 73. The spiral extrusion leaf 74 and the spiral conveying leaf 33 are coaxially driven, and the blade spacing of the spiral extrusion leaf 74 is smaller than that of the spiral conveying leaf 33.

[0068] When the first motor 34 drives the spiral conveying blade 33 to rotate, it can drive the spiral extrusion blade 74 to rotate synchronously, so that the spiral extrusion blade 74 can continuously convey the sludge inside the compression barrel 7 to the right, and cooperate with the compression mechanism to compress the sludge, so as to prevent the sludge from being loose and occupying more space, facilitate the transportation of the sludge, and further squeeze out the sewage in the sludge. In order to facilitate the collection and treatment of the squeezed sewage, a conduit can be set at the bottom of the compression barrel 7 to communicate with the collection bucket 21.

[0069] The extrusion disk 8 is slidably arranged on the inner side of the compression barrel 7 and fits with the inner surface of the compression barrel 7. The control seat 81 is arranged on the right side of the extrusion disk 8. The limiting sleeve 811 is welded and fixed on the left side of the control seat 81 and close to the center. The inner side of the limiting sleeve 811 is slidably connected to the limiting column 82. The left side of the limiting column 82 is welded and fixed to the extrusion disk 8. The limiting sleeve 811 and the limiting column 82 cooperate with each other to limit the extrusion disk 8, thereby improving the stability of the extrusion disk 8.

[0070] The outer side of the limiting sleeve 811 is provided with springs 83 distributed in a circular array, and the two ends of the spring 83 are respectively welded and fixed to the extrusion disk 8 and the control seat 81. Positioning sleeves 831 are provided on the outer side of the spring 83 and near the two ends. The spring 83 can make the extrusion disk 8 and the control seat 81 have a certain amount of rebound, and the spring 83 can improve the extrusion effect of the extrusion disk 8 on the sludge. A hydraulic cylinder 84 is installed on the right side wall of the compression chamber 13. The piston rod of the hydraulic cylinder 84 is fixedly connected to the center of the control seat 81, and the position of the extrusion disk 8 and the control seat 81 can be conveniently regulated by the hydraulic cylinder 84.

[0071] Working principle: First, keep the spring 83 in a static state. Under the elastic action of the spring 83, the limit column 82 slides to the leftmost side of the limit sleeve 811, so that the maximum distance between the extrusion plate 8 and the control seat 81 is maintained. Then, the hydraulic cylinder 84 is operated to drive the control seat 81 to move to the left, and the extrusion plate 8 is driven to move to the left, so that the edge of the extrusion plate 8 contacts the limit block 73. Then, the spiral extrusion blade 74 is operated to drive the sludge inside the compression barrel 7 to move to the right. Since the spiral conveying blade 33 continuously conveys the sludge in the conveying trough 32 to the right, the sludge in the compression barrel 7 gradually increases. Under the cooperation of the spiral extrusion blade 74 and the extrusion plate 8, the sludge can be gradually squeezed and compressed into blocks.

[0072] Furthermore, the hydraulic cylinder 84 is operated to drive the control seat 81 to move slowly to the right, so that the control seat 81 drives the extrusion plate 8 to move to the right. When the extrusion plate 8 moves to the right side of the discharge port 72, part of the sludge can be discharged through the discharge port 72 driven by the spiral extrusion blades 74. Afterwards, the hydraulic cylinder 84 is operated to drive the control seat 81 to move to the left. During the movement to the left, the spring 83 is gradually compressed. Under the action of the hydraulic cylinder 84 and the spring 83, the extrusion plate 8 can squeeze the sludge remaining in the compression barrel 7. By continuously controlling the extrusion plate 8 to move left and right by the hydraulic cylinder 84, the sludge in the compression barrel 7 can be repeatedly squeezed and discharged outward.

[0073] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
