Example

[0022] See also Figure 1-11 , a sewage treatment equipment for environmental engineering, comprising a base 1, a supporting component 4 and a filtering component 3 are provided on the base 1, and a bracket 11 is provided on the base 1 and is in contact with the bottom surface of the supporting component 4, the filtering component 3 has a built-in pressure pump, a folding component 8 is provided at the front end of the supporting component 4, a sewage collecting component 7 is provided on the folding component 8, a sewage suction pipe 6 connected to the sewage collecting component 7 is provided on the supporting component 4, and the other end of the sewage suction pipe 6 is connected to the filtering component 3; The sewage collecting component 7 comprises a collecting component 701, a primary filtering component 702 is provided at the inlet end of the collecting component 701, a conveying component 703 is provided at a position corresponding to the primary filtering component 702 on the collecting component 701, a driving component 704 is provided in the collecting component 701 for transmission cooperation with the conveying component 703 and the primary filtering component 702, a suction pipe 5 is provided at a position corresponding to the end of the conveying component 703 on the supporting component 4, and the other end of the suction pipe 5 is connected to a vacuum box 2 located on the base 1; By setting up the conveying component 703 and the primary filter component 702, when the sewage flows to the sewage suction port 7015, the water flow will push the driving component 704 located in the rotating bin 7014, so that the driving component 704 drives the conveying component 703 and the primary filter component 702 to move, and the sewage will first pass through the primary filter component 702 before entering the collecting bucket 7011. The primary filter component 702 is used to separate the large volume of garbage floating on the water surface, and the moving primary filter component 702 is used to pour the garbage into the conveying component 703. After the conveying component 703 collects the garbage, the vacuum box 2 uses the suction pipe 5 to suck up the garbage, thereby achieving the effect of primary filtering treatment of the sewage and preventing the large volume of garbage floating on the water surface from clogging the sewage suction port 7015 and the sewage suction pipe 6.

[0023] like Figure 6 As shown, the collecting component 701 includes a collecting bucket 7011 arranged on the folding part 8, a float 7013 is arranged under the collecting bucket 7011, an inclined plate 7012 is arranged at the front end of the collecting bucket 7011 to fit with the primary filter component 702, a sewage suction port 7015 connected to the sewage suction pipe 6 is arranged at the bottom of the collecting component 701, a rotating bin 7014 for accommodating the driving component 704 is arranged near the sewage suction port 7015 in the collecting bucket 7011, and a water surface level line 7016 is arranged on the inner wall of the collecting bucket 7011; In the present invention, a sewage collecting component 7 is provided. When it is necessary to treat the sewage on the water surface, the supporting component 4 is unfolded to place the sewage collecting component 7 on the water surface. At the same time, the collecting component 701 in the sewage collecting component 7 is half immersed in water. The buoy 7013 in the collecting component 701 supports the collecting bucket 7011, so that the collecting bucket 7011 floats on the water surface, and the water surface height is consistent with the water surface level line 7016. At this time, the water flow and floating objects such as oil on the water surface will flow into the collecting bucket 7011. At the same time, the sewage suction pipe 6 connected to the filtering component 3 sucks out the sewage in the collecting bucket 7011 through the sewage suction port 7015, so that it enters the filtering component 3 for purification, thereby achieving the purpose of collecting and treating the sewage on the water surface, reducing the workload of large-scale sewage suction, and improving the efficiency of sewage treatment. In addition, by using the float 7013, the collecting bucket 7011 can always float on the water surface, and the height of the water surface can be consistent with the water surface level line 7016 inside the collecting bucket 7011. In this way, the supporting component 4 only needs to be subjected to force when unfolding and folding, which greatly shortens the working time of the supporting component 4, increases its service life, and ensures that the immersion depth of the collecting bucket 7011 remains consistent.

[0024] like Figure 4 As shown, the primary filter assembly 702 includes a driven roller shaft 7021 and an active roller shaft 7022, the driven roller shaft 7021 is connected to the inner wall of the collecting bucket 7011, and both ends of the active roller shaft 7022 are provided with support frames 7024 connected to the collecting bucket 7011, the end surface of the active roller shaft 7022 is transmission-connected to the driving assembly 704, and a primary filter screen 7023 is provided between the driven roller shaft 7021 and the active roller shaft 7022; By setting up the primary filter 7023, the primary filter 7023 can be kept taut by the support of the active roller 7022 and the driven roller 7021, and can move upward by the rotation of the active roller 7022. At the same time, a soft brush is provided on the primary filter 7023, which can grab garbage floating on the water surface and transport it upward, so that the garbage is separated from the water flow and falls into the transport component, thereby achieving preliminary filtration when collecting surface sewage to prevent garbage blockage.

[0025] like Figure 4 As shown, the conveying assembly 703 includes a conveying trough 7031 disposed on the collecting hopper 7011 and vertically aligned with the top of the primary filter assembly 702, the end surface of the conveying trough 7031 is aligned with the suction pipe 5, and an auger 7032 is disposed in the conveying trough 7031 for transmission cooperation with the driving assembly 704; By setting up the auger 7032, the auger 7032 can rotate under the drive of the driving component 704, and use the rotation to push the garbage in the conveying trough 7031 to the center, so that the garbage moves to a position close to the suction pipe 5, and then uses the negative pressure in the vacuum box 2 and the suction pipe 5 to suck the garbage into the vacuum box 2, thereby achieving the purpose of collecting the garbage. In addition, the vacuum box 2 is used to ensure suction while preventing the garbage from contacting the suction fan, thereby effectively ensuring the long-term stable operation of the equipment.

[0026] like Fig.10 As shown, the driving assembly 704 includes an impeller 7041 that rotates in the rotating bin 7014, a chain wheel set 7042 connected between the impeller 7041 and the auger 7032, and a gear set 7043 that is disposed between the auger 7032 and the active roller shaft 7022; By setting the impeller 7041, when the sewage flows into the collecting bucket 7011, the impeller 7041 will be pushed to rotate counterclockwise, and the chain wheel group 7042 will correspondingly drive the auger 7032 to rotate, so that the auger 7032 pushes the garbage to the center, and the auger 7032 will use the gear group 7043 to drive the active roller 7022 to rotate clockwise when rotating, thereby making the primary filter screen 7023 move upward, so as to transport the garbage to the conveying trough 7031.

[0027] like Figure 3 As shown, the support component 4 includes a rotating seat 401 arranged on the base 1, a main support arm 403 and a first hydraulic cylinder 402 are hinged on the rotating seat 401, the top end of the first hydraulic cylinder 402 is hinged to the main support arm 403, a secondary support arm 405 is hinged to the top end of the main support arm 403, a second hydraulic cylinder 404 is arranged between the secondary support arm 405 and the main support arm 403, a connecting frame 406 is arranged at the front end of the secondary support arm 405, and a supporting shaft 407 connected to the folding component 8 is arranged in the connecting frame 406; By setting the first hydraulic cylinder 402 and the second hydraulic cylinder 404, the first hydraulic cylinder 402 can adjust the angle between the main support arm 403 and the rotating seat 401, and the second hydraulic cylinder 404 can adjust the angle between the auxiliary support arm 405 and the main support arm 403. The two cooperate with each other to achieve the effect of folding and unfolding. In this way, the sewage collecting component 7 can be placed on the water surface when working, and the sewage collecting component 7 can be moved out of the water surface when not working, so as to avoid the problem of the sewage collecting component 7 being easily corroded due to long-term immersion in water. Example

[0028] refer to Figure 7The specific folding component 8 includes a third hydraulic cylinder 801 disposed in the secondary support arm 405, and a rotating frame 803 that rotates with the support shaft 407. A connecting rod 802 connected to the third cylinder is disposed between the rotating frames 803, and a notch corresponding to the movement path of the rotating frame 803 is opened in the connecting rod 802. A fixed frame 804 is disposed on the side of the rotating frame 803, and the fixed frame 804 is connected under the collecting bucket 7011. By setting the connecting rod 802 and the rotating frame 803, when folding work is required, the third hydraulic cylinder 801 pushes the connecting rod 802, and the connecting rod 802 drives the rotating frame 803 to move downward, and the rotating frame 803 rotates around the support shaft 407 to fold the fixed frame 804 toward the auxiliary support arm 405, so that the sewage collecting component 7 on the fixed frame 804 is folded on the side of the auxiliary support component 4, thereby achieving the purpose of folding and storing the sewage collecting component 7, further reducing the space occupied by it, and facilitating the transportation and placement of the equipment, and a slot corresponding to the movement path of the rotating frame 803 is opened in the connecting rod 802, so that the linear movement of the connecting rod 802 can be matched with the rotational movement of the rotating frame 803.

[0029] like Figure 8 As shown, a pin 805 is rotatably provided in the fixed frame 804, the other end of the pin 805 is connected to the rotating frame 803, and a coil spring 806 connected to the fixed frame 804 is sleeved on the outer side of the pin 805; By setting the pin shaft 805 and the coil spring 806, the pin shaft 805 can be used to connect the fixed frame 804 with the rotating frame 803, and the fixed frame 804 can rotate around the pin shaft 805. When the sewage collecting component 7 is placed on the water surface, the buoy 7013 inside it will make the sewage collecting component 7 parallel to the water surface. Relying on the characteristic of the buoy 7013 floating in the water, the fixed frame 804 can automatically adjust its own level. The coil spring 806 mounted on the pin shaft 805 can use its own elasticity to reset the fixed frame 804 after the buoy 7013 leaves the water surface, so that the fixed frame 804 and the sewage collecting component 7 will not shake at will in the folded and stored state.

[0030] like Figure 1 , 11 As shown, a stretching component 9 is provided under the support component 4, and a cable 10 connected to the sewage suction pipe 6 is provided in the stretching component 9. The stretching component 9 includes a first pulley 901 and a second pulley 902 provided under the support component 4 and cooperating with the cable 10. A sliding rod 903 is provided under the support component 4 near the second pulley 902, and a counterweight block 904 is slidably sleeved on the sliding rod 903, and the counterweight block 904 is connected to the cable 10; By setting the counterweight block 904 and the cable 10, when the sewage collecting component 7 is unfolded, the sewage suction pipe 6 connected thereto will be straightened, and the sewage suction pipe 6 will drive the counterweight block 904 to move upward through the cable 10 when straightened. The straightened sewage suction pipe 6 can avoid the problem of sagging and storing sewage. When the sewage collecting component 7 is folded, the sewage suction pipe 6 connected thereto will be in a relaxed state. At this time, the counterweight block 904 moves downward along the slide bar 903 under the action of gravity, and pulls the sewage suction pipe 6 through the cable 10, so that the sewage suction pipe 6 is pulled to the side of the secondary support arm 405, preventing the sewage suction pipe 6 from sagging and affecting the storage work.

[0031] like Figure 2 As shown, the filter component 3 includes a multi-stage sedimentation tank 301 connected to the sewage suction pipe 6, a biofilm filter tank 302 connected to the multi-stage sedimentation tank 301, and a disinfection treatment tank 303 connected to the biofilm filter tank 302; After the sewage is pumped into the filter element 3, the coarse particles, surface oil and suspended matter in the sewage are first separated by the multi-stage sedimentation tank 301, and then the impurities in the sewage are further removed by the biofilm filter box 302. Finally, the filtered water is disinfected by the disinfection treatment box 303 so that the water quality can meet the discharge standards.

[0032] like Figure 1 , 3 As shown, the front end of the connecting frame 406 is provided with a flow divider 12, and the two sides of the flow divider 12 are in contact with the collecting bucket 7011; By setting up a diverter hood 12, which is located between the collecting buckets 7011 on both sides and has its bottom submerged in water, the diverter hood 12 can be used to disperse the water flow to both sides, so that the surface water flows into the sewage collecting components 7 on both sides, preventing the surface sewage from flowing out from the gap of the supporting component 4, thereby ensuring the comprehensiveness of the sewage treatment.

[0033] Working principle: When working, the first hydraulic cylinder 402 first unfolds the main support arm 403, and then the second hydraulic cylinder 404 unfolds the auxiliary support arm 405, and then the rotating seat 401 rotates it 180 degrees, and then the third hydraulic cylinder 801 pushes the rotating frame 803 through the connecting rod 802, so that the rotating frame 803 is unfolded through the fixed frame 804 at the bottom of the pin shaft 805, and the fixed frame 804 is used to unfold the sewage collection component 7, and then the supporting component 4 is used to place the sewage collection component 7 on the water surface, and then the second hydraulic cylinder releases pressure; The collecting bucket 7011 is suspended on the water surface by the float 7013, and the water surface is aligned with the horizontal line inside the collecting bucket 7011. Then the sewage passes through the primary filter screen 7023 and enters the collecting bucket 7011, and is sucked into the filter component 3 through the sewage suction port 7015 and the sewage suction pipe 6 for treatment. While the sewage flows, the impeller 7041 is pushed, so that the impeller 7041 drives the auger 7032 and the active roller 7022 to rotate through the chain wheel group 7042 and the gear group 7043. The active roller 7022 drives the primary filter screen 7023 to move upward, and the large volume of garbage floating on the water surface is sent to the conveying trough 7031. At the same time, the auger 7032 pushes the garbage to the center, and finally the suction pipe 5 and the vacuum box 2 collect the garbage.

[0034] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
