Description

Technical Field

[0002] The sewage treatment in residential areas is an important part of urban environmental protection. A reasonable sewage treatment plan can not only protect the environment but also improve the living quality of residents.

[0003] Currently, the sewage of single or multiple buildings in residential areas is collected through pipe networks. Generally, a sewage well is set at the confluence of the pipe networks. It collects large particulate matters and some suspended matters in the sewage through sedimentation, which can prevent the pipe networks from being blocked and play a certain buffering role to prevent the subsequent treatment equipment from being impacted when the water flow is too large.

[0004] However, at the same time, there are also some problems with the sewage well: the sediment and silt collected in the sewage well generally need to be regularly cleaned by a sewage suction truck. In this cleaning method, sometimes, due to excessive pollutants in the sewage per unit time, the sewage suction truck cannot clean in time, resulting in excessive accumulation of sediment in the sewage well, reduction of the space in the sewage well, and then affecting the flow of sewage in the pipe network, ultimately leading to sewage overflow or pollutant blockage of the pipeline, affecting the drainage system of the entire residential area; at the same time, the inner wall of the sewage well is also prone to attaching pollutants, which will lead to a reduction in its capacity after long-term accumulation, and then increase the probability of the above situation occurring.

[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the invention can be implemented in many different ways defined and covered by the claims.

[0030] Refer to Figure 1 and Figure 2 , a sewage integrated continuous automatic treatment device, including a collection bin 1. A water inlet pipe 11 is fixedly connected and communicated with the upper position of the side wall of the collection bin 1. A support rod 2 is fixedly connected to the center of the bottom inside the collection bin 1. The upper end of the support rod 2 is connected with a water level control unit 3, and the side wall of the support rod 2 is connected with a shredding unit 4.

[0031] Refer to Figures 4 - 6 , the shredding unit 4 includes an I-shaped mounting seat 41. The I-shaped mounting seat 41 is composed of a mounting cylinder rotatably sleeved on the support rod 2 and annular connecting plates symmetrically fixed on both ends of the mounting cylinder up and down. The mounting cylinder can slide relatively up and down along the support rod 2. The upper end surface of the upper annular connecting plate is connected with a driving unit 5. Two annular frames 42 are symmetrically rotatably connected to the upper and lower sides of the side wall of the mounting cylinder. The annular frames 42 can slide up and down along the mounting cylinder. The two annular frames 42 are fixedly connected by a plurality of round rods 43 arranged evenly in the circumferential direction. A return spring 44 is arranged between the annular frame 42 and the annular connecting plate. The two ends of the return spring 44 are respectively in sliding contact with the annular frame 42 and the I-shaped mounting seat 41.

[0032] Refer to Figure 2 , Figure 5 andFigure 6 A plurality of mounting rings 45 are slidably sleeved on the side wall of the mounting cylinder up and down evenly, and the mounting rings 45 can rotate relative to the mounting cylinder. A plurality of grinding sheets 46 corresponding to the round rods 43 are fixedly connected to the side wall of the mounting rings 45 along the circumferential direction evenly. The end of the grinding sheet 46 far from the support rod 2 is fixedly connected to the round rod 43. A plurality of crushing blades 47 are fixedly connected to the upper and lower parts of the side wall of the mounting cylinder between two adjacent mounting rings 45. The plurality of crushing blades 47 are arranged evenly along the circumferential direction. A scraping unit 6 for cleaning the inner wall of the collection bin 1 is connected to the two annular frames 42 together. A sewage discharge unit 7 is connected to the lower end of the I-shaped mounting seat 41. A sewage collection bin 8 is fixedly connected to the bottom end of the collection bin 1. A sewage discharge pipe 81 is fixedly communicated with the side wall of the sewage collection bin 8 at a position close to the lower part. The sewage discharge pipe 81 is communicated with the pipe for discharging sewage in the existing pipe network.

[0033] During specific operation, the water inlet pipe 11 is communicated with the pipe network for collecting sewage. Sewage enters the collection bin 1 from the water inlet pipe 11. When the driving unit 5 operates, on the one hand, the I-shaped mounting seat 41 together with the crushing blades 47 thereon rotates, and cooperates with the grinding sheets 46 to cut the larger solid particles in the sewage. On the other hand, the operation of the driving unit 5 also drives the annular frame 42 to rotate in the reverse direction, so as to clean the pollutants attached to the inner wall of the collection bin 1 through the scraping unit 6 on the annular frame 42. When the driving unit 5 operates, it will also drive the I-shaped mounting seat 41 and the annular frame 42 to slide down along the support rod 2 synchronously to increase the cleaning range of the scraping unit 6. When it descends to the lowest end, the driving unit 5 will also make the annular frame 42 slide down relative to the mounting cylinder, so that the crushing blades 47 are in brief contact with the grinding sheets 46, and then the crushing blades 47 are ground to ensure their sharpness.

[0034] When the I-shaped mounting seat 41 moves to the lowest position under the action of the driving unit 5, it will also drive the sewage discharge unit 7 to operate, so that the shredded pollutants and a part of the sewage enter the sewage collection bin 8, and finally are discharged into the pipe network through the pipe connected to the sewage discharge pipe 81.

[0035] Refer to Figure 1 and Figure 2 As shown in, the water level control unit 3 includes a connecting seat 31. The connecting seat 31 is a cylindrical cavity structure with openings at both the upper and lower ends. A through groove is opened on the side wall of the connecting seat 31. The lower end of the connecting seat 31 is fixedly connected to the top end of the support rod 2. A straight rod 32 is fixedly connected to the upper end of the connecting seat 31. The top end of the straight rod 32 is fixedly connected to the collection bin 1. An L-shaped pipe 33 is fixedly communicated with the through groove of the connecting seat 31. A drainage bin 34 is fixedly connected to the outside of the L-shaped pipe 33, and the lower end of the L-shaped pipe 33 is located inside the drainage bin 34. A water outlet pipe 35 is fixedly communicated with the side wall of the drainage bin 34. The height of the water outlet pipe 35 is higher than the height of the lower pipe orifice of the vertical section of the L-shaped pipe 33.

[0036] During specific operation, a certain amount of water is always stored in the drainage bin 34, and the liquid level of the water is higher than the lower pipe orifice of the vertical section of the L-shaped pipe 33 and lower than the water outlet pipe 35. The water above the water outlet pipe 35 is discharged outward through the water outlet pipe 35. When the water inflow volume in the collection bin 1 per unit time is large and the height of the water surface exceeds the height of the connecting seat 31, the sewage above the connecting seat 31 in the collection bin 1 automatically enters the drainage bin 34 along the L-shaped pipe 33, and then enters the external collection device through the water outlet pipe 35.

[0037] Refer to Figure 3 and Figure 6 , the driving unit 5 includes a support plate 51, and the support plate 51 is slidably sleeved on the support rod 2. The upper end surface of the support plate 51 is fixedly connected with a cylinder 52, the fixed section of the cylinder 52 is fixedly connected with the top of the collection bin 1, the upper end surface of the support plate 51 is also fixedly connected with a waterproof motor 53, and the driving shaft of the waterproof motor 53 penetrates through the support plate 51 and its lower end is connected with a rotating assembly 54.

[0038] Refer to Figure 3 and Figure 6 , the rotating assembly 54 includes a first connecting pipe 541, the first connecting pipe 541 is slidably sleeved on the support rod 2, the upper end of the first connecting pipe 541 is fixedly connected with the lower end surface of the support plate 51, the lower end of the first connecting pipe 541 is rotatably sleeved with a central gear 542, the outer side of the central gear 542 is meshed with an interlocking gear 543, the interlocking gear 543 is fixedly connected with the driving shaft of the waterproof motor 53, the outer side of the interlocking gear 543 is meshed with an internal gear ring 544, the internal gear ring 544 is connected with a limiting module 545, and the limiting module 545 is fixedly connected with the upper annular frame 42.

[0039] Refer to Figure 4 and Figure 6 , the limiting module 545 includes a limiting ring plate 5451, and the upper end surface and the lower end surface of the internal gear ring 544 are both fixedly connected with the limiting ring plate 5451. The two limiting ring plates 5451 make the interlocking gear 543 and the internal gear ring 544 always located in the same plane. The limiting ring plate 5451 is slidably connected with the interlocking gear 543. The lower end surface of the lower limiting ring plate 5451 is fixedly connected with a plurality of spring rods 5452 along the circumferential direction evenly. The fixed section of the spring rod 5452 is fixedly connected with the upper end surface of the upper annular frame 42.

[0040] During specific operation, the waterproof motor 53 operates to drive the linkage gear 543 to rotate. On one hand, it drives the central gear 542 to rotate, thereby driving the I-shaped mounting seat 41 and the crushing blade 47 to rotate synchronously through the central gear 542. On the other hand, it drives the internal gear ring 544 to rotate synchronously in the opposite direction, thereby driving the annular frame 42 to rotate synchronously through the limiting ring plate 5451 and the spring rod 5452. The synchronous reverse rotation of the I-shaped mounting seat 41 and the annular frame 42 can drive the crushing blade 47 and the grinding sheet 46 to rotate synchronously in the opposite direction, thereby increasing the relative rotational speed between the two, and further ensuring the crushing effect. When the annular frame 42 rotates, it will also drive the scraping unit 6 to rotate synchronously to clean the inner wall of the collection bin 1.

[0041] Refer to Figure 3 and Figure 8 As shown in FIGS. and, the scraping unit 6 includes a mounting plate 61. A plurality of mounting plates 61 are fixedly connected circumferentially to the end faces of the two annular frames 42 that are away from each other. Two connecting rods 62 are symmetrically and fixedly connected to the end face of the mounting plate 61 that is away from the support rod 2. A T-shaped scraping plate 63 is slidably connected to a plurality of connecting rods 62 on the corresponding mounting plate 61. A ball is rollingly embedded at the bottom of the T-shaped scraping plate 63 to prevent the bottom end of the T-shaped scraping plate 63 from rubbing against the inner wall of the collection bin 1 when it moves to the lower end. A pressing component 64 is commonly connected to the T-shaped scraping plate 63 and the mounting plate 61.

[0042] Refer to Figure 8 As shown in FIGS., the pressing component 64 includes a pressing spring 641. The pressing spring 641 is sleeved on the connecting rod 62, and the pressing spring 641 is located between the mounting plate 61 and the T-shaped scraping plate 63. A limiting plate 642 is fixedly connected to the end of the connecting rod 62 that is away from the support rod 2.

[0043] During specific operation, the rotation of the annular frame 42 drives the mounting plate 61 to rotate, thereby driving the T-shaped scraping plate 63 to rotate synchronously through the connecting rod 62. At the same time, the pressing spring 641 is always in a compressed state, so that the T-shaped scraping plate 63 always abuts against the inner wall of the collection bin 1. When the T-shaped scraping plate 63 rotates relative to the collection bin 1 along with the annular frame 42, it can effectively clean the inner wall of the collection bin 1.

[0044] Refer to Figure 4 As shown in FIGS., the sewage discharge unit 7 includes a second connecting pipe 71. The second connecting pipe 71 is fixedly connected to the lower end of the I-shaped mounting seat 41. The lower end of the second connecting pipe 71 is rotatably connected to a connecting frame 72. A plurality of telescopic rods 73 are evenly and fixedly connected to the lower end of the connecting frame 72. The lower ends of the telescopic rods 73 are all connected to a blocking component 74.

[0045] Refer to Figure 4 and Figure 7, the plugging assembly 74 includes a tapered plug 741. A plurality of sewage outlets corresponding to the telescopic rods 73 are evenly formed in the bottom of the collection bin 1 along the circumferential direction. A tapered plug 741 is arranged in cooperation with the sewage outlets. A round groove is formed through the tapered plug 741 up and down. The upper end surface of the tapered plug 741 is frustum-shaped. A reset module 742 is connected to the upper end of the tapered plug 741. A round pipe 743 is fixedly communicated with the lower end of the tapered plug 741. A cylindrical cylinder 744 is slidably sleeved on the outer wall of the round pipe 743, and the connection between the round pipe 743 and the cylindrical cylinder 744 is sealed. A plurality of air holes are evenly formed in the upper end surface of the cylindrical cylinder 744. A plurality of folding rods 745 are fixedly connected to the side wall of the cylindrical cylinder 744. The upper ends of the folding rods 745 are fixedly connected to the bottom of the collection bin 1. An annular plate 746 is fixedly sleeved on the lower end of the round pipe 743. A tapered baffle 747 for blocking sewage is fixedly sleeved on the upper end of the round pipe 743.

[0046] Refer to Figure 7 , the reset module 742 includes a piston 7421. A piston 7421 is slidably and cooperatively connected in the tapered plug 741 and the round pipe 743. The upper end of the piston 7421 is fixedly connected to the lower end of the telescopic rod 73. A waterproof outer shell 7422 is fixedly connected to the upper end of the piston 7421. The waterproof outer shell 7422 is slidably connected with the telescopic rod 73, and the connection between the two is sealed. A limit frame 7423 is slidably sleeved on the upper end of the waterproof outer shell 7422. The limit frame 7423 is fixedly connected to the inner side wall of the collection bin 1. The limit frame 7423 and the piston 7421 are connected by a connection spring 7424. Initially, the connection spring 7424 is in a compressed state so that the tapered plug 741 abuts against the bottom plate of the collection bin 1. The cavity below the piston 7421 is filled with hydraulic oil.

[0047] Refer to Figure 2 , Figure 3 and Figure 7 , specifically during operation, when the waterproof motor 53 drives the annular frame 42 and the I-shaped mounting seat 41 to rotate, the piston rod of the air cylinder 52 also extends synchronously, pushing the support plate 51 to slide downward, and then driving the I-shaped mounting seat 41 to move downward through the first connecting pipe 541. At this time, both reset springs 44 are in a compressed state. Therefore, the downward movement of the I-shaped mounting seat 41 will drive the annular frame 42 to move downward synchronously. On the one hand, it drives the T-shaped scraper 63 to move downward synchronously, increasing its cleaning range. On the other hand, it pushes the connecting frame 72 and the telescopic rod 73 to move downward synchronously through the second connecting rod 62.

[0048] In the initial stage of the downward movement of the connecting frame 72, the telescopic rod 73 is driven to contract. After moving downward a certain distance, when the telescopic rod 73 contracts to the maximum extent, the whole telescopic rod 73 moves downward, pushing the piston 7421 to slide downward along the inner circular groove of the tapered plug 741. Thus, the annular plate 746, the circular tube 743 and the tapered plug 741 are pushed upward by the hydraulic oil. Furthermore, a gap is generated between the inclined section sewage outlet of the tapered plug 741. The crushed dirt and the sewage will flow together along this gap into the sewage collection bin 8, and finally be pumped to the outside by the sewage discharge pipe 81. During this process, the connecting spring 7424 is further compressed.

[0049] During the process of the telescopic rod 73 continuing to move downward after contracting to the maximum extent, the lower end of the T-shaped scraper 63 will abut against the bottom of the collection bin 1 and thus will no longer move downward, and the annular frame 42 will also no longer move downward. At this time, the I-shaped mounting seat 41 continues to move downward a certain distance under the drive of the support plate 51 and the first connecting pipe 541. Furthermore, the annular frame 42 will move upward relative to the I-shaped mounting seat 41, driving the crushing blade 47 to contact the grinding piece 46 above it, thereby grinding it to increase its sharpness and thus ensuring the crushing effect.

[0050] After the sewage in the collection bin 1 is drained, the telescopic rod 73 moves upward to reset. At this time, the tapered plug 741 is pressed against the bottom plate of the collection bin 1 again under the action of the connecting spring 7424. The hydraulic oil in the cavity also resets to the initial height during this process, pushing the piston 7421 to move upward to reset.
