SEWAGE DETECTION AND DISCHARGE SYSTEM LU504941

TECHNICAL FIELD

[0001] The present invention relates to the technical field of landfill leachate treatment, and particularly relates to a sewage detection and discharge system,

BACKGROUND ART

[0002] Landfill leachate is a kind of high-concentration organic wastewater with complex components, and the leachate also contains a lot of impurities and wastes, such that after filtration, a large number of sediments and a large number of floating wastes will be produced in a wastewater tank. These sediments, if not treated in time, will reduce the volume of the wastewater tank, resulting in overflow when the usable volume of the wastewater tank is not reached. The overflow will bring out floating wastes together, which not only influences the environment, but also causes potential safety hazards in use. The liquid level of the leachate is usually measured by directly placing, by means of a connecting wire, a measuring head of a liquid level indicator into the liquid to be measured, or by directly using an ultrasonic liquid level indicator outside the liquid level. However, the connecting wire may bend or swing to a certain extent, resulting in an inaccurate measurement result. The direct measurement by the ultrasonic liquid level indicator from above the liquid level may be influenced by many floating dirt covering the surface of a leachate tank, because the floating dirt has a certain thickness, and the thickness of these floating dirt may also be included in the level of the leachate when the ultrasonic liquid level indicator measures the liquid level, resulting in data deviating from the exact value. In this way, the staff cannot learn about the real liquid level of the leachate, Le., the liquid level of the leachate in the leachate tank cannot be controlled within an appropriate range, which may lead to overflow of the dirt.

SUMMARY OF THE INVENTION

[0003] In view of the defects mentioned above of the prior art, a technical problem to be solved by the present invention is to provide a sewage detection and discharge system, which can not only discharge precipitated entrainment in a timely manner and maintain the liquid storage volume, but also discharge floating objects and relieve blockage in a timely manner, and at the same time, facilitates liquid level measurement of leachate.

[0004] In order to solve the technical problems described above, the present invention adopts a technical solution described as below: a sewage detection and discharge system is provided, and

C52P15LU-LTLUP230715 2 01.08.2023 the sewage detection and discharge system comprises a leachate tank body communicated with J504941 a leachate drainage pipe, a slagging mechanism arranged at a sludge discharge trough at the bottom of the leachate tank body, a dredging mechanism arranged at an outlet in the middle of the leachate tank body, a sewage tank communicated with a water outlet end of the dredging mechanism and a detection device arranged in the sewage tank; the slagging mechanism comprises a shield cover arranged in a length direction of the sludge discharge trough and configured to bear leachate and entrainment thereof, and an agitating device arranged in the shield cover in a length direction of the shield cover, two ends of the shield cover being rotatably arranged in the sludge discharge trough by means of a first support and a second support respectively, the shield cover having an opening distributed in the length direction of the shield cover, the agitating device being configured to agitate and dredge the entrainment in the leachate, the entrainment passing through the agitating device and being discharged along a lower end of the sludge discharge trough when the shield cover rotates; the dredging mechanism comprises an X-axis fixed rail set arranged at the outlet of the leachate tank body, a dredging module slidably arranged on the X-axis fixed rail set and being capable of opening and closing in a length direction of the X-axis fixed rail set, and a Y-axis movable rail set arranged above the X-axis fixed rail set, an oblique guide rail set being arranged on the Y-axis movable rail set corresponding to the dredging module, an upper end of the dredging module being rotatably arranged in the oblique guide rail set to be able to open and close in the length direction of the X-axis fixed rail set under an oblique reciprocating force of the oblique guide rail set; and the detection device comprises a telescopic measuring mechanism erected above the sewage tank, a first ultrasonic meter coaxially arranged at an upper end of the telescopic measuring mechanism, and a lifting mechanism for driving the telescopic measuring mechanism to expand and contract in a vertical direction.

[0005] By adopting the structure described above, the entrainment in the leachate may settle into the sludge discharge trough and fall into the shield cover through the opening of the shield cover after the leachate flows into the leachate tank body. When the sediment reaches a certain volume, the shield cover is rotated and the agitating device is started at the same time. The agitating device pushes the sediment to move to an outlet at the lower end of the sludge discharge trough while the precipitated entrainment is poured out from the opening of the shield cover, so as to quickly discharge the sediment and prevent excessive residue of the sediment. In addition, the liquid storage volume of the leachate tank body can be restored to prevent the leachate from overflowing before the liquid storage volume of the leachate tank body is reached, which, on the one hand, protects the environment, and on the other hand, ensures normal

C52P15LU-LTLUP230715 3 01.08.2023 operation of the leachate tank body to avoid potential safety hazards in use. The dredging U504941 module is opened and closed in the length direction of the X-axis fixed rail set under the oblique reciprocating force of the oblique guide rail set when the leachate 1s accumulated at the outlet of the leachate tank body, so as to pinch and cut the discharged leachate and its floating objects back and forth, and dynamically prevent blockage caused by accumulation of the floating objects while the floating objects are discharged. The sewage tank is provided with the first ultrasonic meter, the telescopic measuring cylinder capable of extending downwards and contracting upwards in the vertical direction and a filter cover for filtering the dirt, so that a real liquid level of the leachate can be measured without being influenced by the floating dirt.

Meanwhile, the lifting mechanism used in cooperation with the telescopic measuring cylinder is provided such that the device has a more reasonable overall structure and is convenient to operate.

[0006] The present invention has the following beneficial effects: the shield cover and the agitating device are provided to periodically and orderly discharge sediments, so that the slagging efficiency can be improved; the dredging module capable of opening and closing back and forth is provided to dynamically prevent blockage caused by accumulation of the floating objects while discharging the floating objects; and the Lifting mechanism is provided to drive the telescopic measuring cylinder, so that the efficiency of liquid level measurement can be improved and the use is convenient.

[0070] The principle of the present invention is described as below.

[0071] As shown in FIG. 1 to FIG. 6, the entrainment in the leachate may settle into the sludge discharge trough 11 and fall into the cover body 30 through the opening of the shield cover after the leachate flows into the leachate tank body |. When the sediment reaches a certain volume, the second driving motor 42 is started to drive a connecting panel 33 and the second sleeve 32 to rotate synchronously, Le., to drive the cover body 30 to rotate synchronously, to pour out the precipitated entrainment from the opening of the cover body. At the same time, the first driving motor 41 also needs to be started. The first spiral blade 431 and the second spiral blade 431 push the sediment to move to the outlet at the lower end of the sludge discharge trough 11. Since the outlet of the sludge discharge trough 11 is in the middle position and the spiral directions of the two spiral blades are opposite to each other, when rotating, the two spiral blades can achieve the purpose of gathering the entrainment of the sediment in the middle, so as to quickly discharge the sediment, restore the liquid storage volume of the leachate tank body 1 and prevent the leachate from overflowing before the liquid storage volume of the leachate tank body 1 is reached, which, on the one hand, protects the environment, and on the other hand, ensures normal operation of the leachate tank body 1 to avoid potential safety hazards in use.

[0072] Finally, as shown in FIG. 1 and FIG. 4, the provided power motor drives the rotating shaft 81 to rotate. An accommodating cavity is formed between two adjacent partitions. As the rotating shaft 81 rotates, the entrainment discharged from the sludge discharge trough 11 is orderly discharged in batches, which facilitates orderly collection of the discharged materials at the discharge port of the box body 8 while ensuring the slagging efficiency.

[0073] The power motor, the first driving motor 41 and the second driving motor 42 are connected with a PLC for better automatic and intelligent operation management, which can greatly reduce the work intensity. Since the PLC involves only use control but not program

C52P15LU-LTLUP230715 16 01.08.2023 setting, and the PLC is a common apparatus, its specific connection or settings will not bg 504941 repeated herein,

[0074] As shown in FIG 1, FIG. 2 and FIG. 7 to FIG. 17, when the liquid level of the leachate rises to the outlet of the leachate tank body, the leachate moves to the outlet together with the floating objects. Because of accumulation of the floating objects, in order to prevent the accumulation from influencing discharge of the leachate, which causes the leachate in the leachate tank to overflow from the opening at the upper end of the leachate tank, it is necessary to agitate the floating objects.

[0075] Specifically, as shown in FIG. 7, FIG. 8, and FIG. 14 to FIG. 16, the driving motor 232 is started on the PLC to drive a support block 233 to move in the axial direction of the guide rod 235, and the first Y-axis movable rail 220 and second Y-axis movable rail 240 that are connected to each other also move synchronously. The first Y-axis movable rail 220 is provided with six first left oblique guide rails 21la and six first right oblique guide rails 212a. Six included angles ul are formed between the six first left oblique guide rails 21 la and the X axis of the first Y-axis movable ral 220, and the values of two adjacent included angles al sequentially increase by equal difference from left to right. Six included angles B1 are formed between the six first right oblique guide rails 212a and the X axis of the first Y-axis movable rail 220, and the values of two adjacent included angles Bi sequentially increase by equal difference from right to left.

[0076] Similarly, the second Y-axis movable rail 240 is correspondingly provided with six second left oblique guide rails 214a and six second right oblique guide rails 215a. Six included angles a2 are formed between the six second left oblique guide rails 214a and the X axis of the first Y-axis movable rail 220, and the values of two adjacent included angles a2 sequentially increase by equal difference from left to right. Six included angles B2 are formed between the six second right oblique guide rails 215a and the X axis of the first Y-axis movable rail 220, and the values of two adjacent included angles B2 sequentially increase by equal difference from right to left Meanwhile, the first Y-axis movable rail 220 is further provided with a first Y-axis guide rail 213 in coaxial with the symmetry axis Li, and the second Y-axis movable rail 240 is further provided with a second Y-axis guide rail 216 located right below the first Y-axis guide rail 213.

[0077] As shown in FIG. 7, FIG 11, FIG. 12, FIG. 13, FIG. 16 and FIG. 17, a connecting shaft 330 is arranged between guide rails at corresponding positions on the first Y-axis movable rail 220 and the second Y-axis movable rail 240 in a threading manner. When the Y-axis movable rail moves linearly in the Y-axis direction, a force in an Fy- or Fy. direction, acting on the

C52P15LU-LTLUP230715 17 01.08.2023 connecting shaft 330, will generate a component force in an Fx+ or Fx. direction. The component 504941 force pushes the connecting shaft 330 to move linearly in the X-axis direction, and enables the two side walls of the second side wing 322 to be snapped into the wide groove 312a of the first side wing 312 of the adjacent dredging block 310 to form a pinching and cutting action.

Meanwhile, since the values of the adjacent included angles al and «2 and the values of the included angles BI and B2 are of equal difference, each connecting shaft 330 is prevented from being blocked due to the difference of the moving distance. In addition, the guide rails at the corresponding positions are symmetrically arranged, which ensures the integrity and the stability of movement. As the driving motor 232 drives the two connected Y-axis movable rails to linearly reciprocate in the Y-axis direction, the first side wing 312 and the second side wing 322, which are arranged opposite to each other, on two adjacent connecting shafts 330, also move back and forth. The reciprocating pinching and cutting action generated thereby can conveniently achieve the function of agitating the floating objects to prevent the floating objects from accumulation.

[0078] As shown in FIG. 7 to FIG, 10, during movement of the Y-axis guide rail, since the first lubricating ring 217 is embedded into the first Y-axis guide rail 213, the lower end surface of the cover plate 34 is attached to the upper end surface of the first lubricating ring 217. The second lubricating ring 218 is embedded into the second left oblique guide rail 214a, the second right oblique guide rail 215a and the second Y-axis guide rail 216, the groove wall at the upper end of the ring groove on the connecting shaft 330 is attached to the upper end surface of the second lubricating ring 218, and the groove wall at the lower end of the ring groove is attached to the lower end surface of the second lubricating ring. The third lubricating ring 121 is embedded into the rail groove 120 of the lower fixed rail 100a, and the lower end surface of the connecting shaft 330 is attached to the upper end surface of the third lubricating ring 121. The upper slider 320b extends into the fourth lubricating ring 219, and the outer wall of the upper slider 320b is attached to the inner side wall of the fourth lubricating ring 219. In this way, the stability of movement of the connecting shaft 330 in the X direction can be improved. Meanwhile, the movement wear can be reduced and the service life can be prolonged.

[0079] I should be noted that the inner side wall of the fourth lubricating ring 219 and the inner side wall of the third lubricating ring 121 are both of conical structures, and correspondingly, the outer side walls of the upper slider 320b and the lower slider 320a are also adaptively of conical structures. Under the action of gravity, the conical-surface fitting is more stable, and the connecting shaft 330 is not prone to displacement.

C52P15LU-LTLUP230715 18 01.08.2023

[0080] During use, water 15 drawn off in the position of the flushing pipe 10 to spray and wash 504941 the position of the dredging block 310 so as to prevent the floating objects from remaining. The driving motor 232 is turned off when the liquid level falls below the plane where the platform 12 is located. Meanwhile, if the liquid level of leachate keeps rising, the second ultrasonic meter 102 may send a signal to the connected PLC upon detecting that the liquid level is too high, and the PLC may send a signal to an alarm device, 50 as to give an early warning quickly in a timely manner to prevent the leachate from overflowing.
