Description

Technical Field

[0002] The leachate in the waste incineration power plant mainly comes from the moisture in the garbage itself. The landfill will have some rainwater. The food waste is mainly the wastewater from the catering enterprises, which is usually treated together with the garbage. The garbage leachate is a high-concentration organic wastewater with complex components. At present, the leachate is blocked by various types of garbage from the leachate during the filtration process, causing the leachate filtration system to be often blocked and paralyzed, resulting in frequent overflow of leachate, causing serious pollution to the site, seriously affecting normal production and the on-site environment. The main reason is due to the static grid in the leachate filter. When the leachate is filtered through the filtration system, the floating objects clog the grid, causing the filtration to be paralyzed. At the same time, after the filtration treatment, a large amount of sediment and a large amount of floating waste will be generated in the wastewater pool. If these sediments are not handled in time, the volume of the wastewater pool will be reduced, causing the wastewater pool to overflow before reaching the usage volume. At the same time, the overflow will bring out the floating objects, which not only affects the environment but also causes safety hazards in use. Utility Model Content

[0081] Similarly, the second Y-axis movable rail 240 is also provided with a second Y-axis guide rail 216 located directly below the first Y-axis guide rail 213.

[0082] In addition, a third lubricating ring 121 is embedded in the rail groove 120 of the lower fixed rail 100a, the lower slider 320a extends into the rail groove 120 and fits against the inner wall of the third lubricating ring 121, and the lower end surface of the connecting shaft 330 fits against the upper end surface of the third lubricating ring 121.

[0083] A flushing pipe 92 is provided in the leachate tank body 91, and the water outlet of the flushing pipe 92 is directed toward the dredging block 310, for flushing the dredging block 310 to prevent floating residues from accumulating on the dredging block 310; a second ultrasonic liquid level measuring instrument 93 connected to the PLC controller is also provided in the leachate tank body 91 to monitor the liquid level of the leachate in the leachate tank body 91, so as to adjust the speed of the power motor, adjust the speed of the rotating shaft 801, and discharge the leachate at the box body 80 in a timely manner to lower the liquid level of the leachate.

[0084] The operating principle of this utility model is as follows:

[0085] like Figures 1 to 4As shown, the first ultrasonic liquid level measuring instrument 2 and the driving motor 4 are arranged on the cylinder 1 and connected with the PLC controller. When the height of the accumulated material is low, the reflection time of the sound beam is long, the PLC controller does not send a start command to the driving motor 4, and the leachate is automatically discharged along the cylinder 1. When the height of the accumulated material is high, the reflection time of the sound beam is short, the first ultrasonic liquid level measuring instrument 2 sends a signal to the PLC controller, and the PLC controller sends a start command to the driving motor 4, so that the spiral propeller drives the shaftless spiral blade 3 to rotate and drives the accumulated material to move to the storage pool, timely dredging the cylinder 1. When the height of the accumulated material decreases to a suitable height, the reflection time of the sound beam is long again, the PLC controller sends a shutdown command to the driving motor 4, the spiral propeller is closed, the shaftless spiral blade 3 stops rotating, and the leachate continues to be automatically discharged along the cylinder 1.

[0086] It should be noted that the PLC controller only selects the minimum value of the two first ultrasonic liquid level measuring instruments 2, i.e. the shortest reflection time and the accumulated height, i.e. sending a signal to the PLC controller, and the PLC controller sends a start command to the driving motor 4. When the height of the accumulated material decreases, the reflection time of the two first ultrasonic liquid level measuring instruments 2 returns to a longer value, and then a signal is sent to the PLC controller, and the PLC controller sends a shutdown command to the driving motor 4. In addition, the structure of the shaftless spiral blade 3 can avoid the winding of plastic bags, cloth strips and other garbage around the shaft core.

[0087] As shown in Figure 1 , Figure 2 , Figures 5 to 17 When the leachate enters the housing 35 through the water inlet cylinder 331, the driving motor 2 is started, the transmission shaft 14 drives the four knife holders and the three auger blade sleeves 55 to rotate together, and drives the sewage to rotate together. The blades on the four knife holders cut the waste in the sewage during rotation. It should be noted that although the first blade 513, the second blade 523, the third blade 533 and the fourth blade 543 have the same direction as the rotation direction of the transmission shaft 14, the flow rate of the outer circle of the sewage away from the transmission shaft 14 will decrease, and the rotation speed of the transmission shaft 14 remains unchanged, i.e. the cutting speed of the twelve blades remains unchanged. The speed difference generated thereby can fully crush the waste, and the leachate meeting the filtration standard can be filtered and discharged. It should be noted that nine blades 333 are arranged equidistantly on the inner wall of the outer cylinder 1, which cooperate with the blades on the knife holder to further crush the waste, so as to achieve the purpose of refining the waste and avoiding blockage of the leachate discharge. In addition, since the sewage discharge pipe 24 is arranged, the purpose of quickly removing the blockage can also be achieved when the discharge is not smooth or needs to be cleaned.

[0088] At the same time, as shown in Figure 1 , Figure 2 , Figures 18 to 20As shown, the electric top cylinder 66 is started to move back and forth, which also drives the first guide block 651 to move back and forth synchronously in the horizontal direction. One side of the first guide plate 651 is meshed with a transmission tooth 63. The transmission tooth 63 is meshed with two sets of driven gear sets (not shown) on one side, and is meshed with the second guide plate 652 on the other side. Each driven gear set includes seven driven gears 61 that are arranged side by side and meshed in sequence. That is, the second guide plate 652 and the two sets of driven gears 61 also reciprocate synchronously with the transmission tooth 63. The reciprocating rotation of the driven gear 61 drives The vertically mounted filter shaft 62 rotates back and forth. In order to avoid jamming, the frequency of the reciprocating rotation should be accelerated, which requires adjusting the telescopic frequency of the electric top cylinder 66. In this way, in the gap between the two adjacent filter shafts 62, the reciprocating rotation of the filter shaft 62 forms a vortex, which can form a surging flow in the gap, accelerating the rapid passage of the leachate. If large impurities that have been missed by the crushing move to the gap, it is not easy to cause jamming within a shorter stroke range. At the same time, it can quickly switch to reverse rotation to bring out larger impurities in the reverse direction, avoiding clogging of the gap between the filter shafts 62.

[0089] When cleaning is required, Figure 2 、 Figure 18 、 Figures 21 to 24 As shown, first close the cylinder 1 and the electric butterfly valve (not marked) at the position of the drain pipe 9, turn on the transmission motor 352 and the electric top cylinder 66, the tool holder group rotates unidirectionally, the filter shaft 62 rotates reciprocatingly, and then water enters from the water supply pipe 7. When the water flows through the first connecting pipe 71, it is diverted and flows along the first connecting pipe 71 into the first annular water pipe 711 arranged in the drain pipe 9, and is sprayed from the seven first nozzles 712 to clear the residue at the position of the drain pipe 9; when the water flows through the second connecting pipe 72, it is diverted to the second annular water pipe 721 arranged outside the sewage pipe 24, and is sprayed from the second nozzle 722 extended into the sewage pipe 24 to clear the residue in the sewage pipe 24, and then flows to the drain pipe 9 for discharge.

[0090] The water flows through the third connecting pipe 73 and is divided into two streams along the third connecting pipe 73 to the position of the three-way valve 731. One stream flows into the third annular water pipe 732 provided in the water outlet cylinder 332 and is sprayed out by the third nozzle 733. The water outlet of the third nozzle 733 is inclined toward the center line of the third annular water pipe 732, that is, the water outlet direction is inclined downward toward the filter shaft 62. The water sprayed by the third nozzle 733 cooperates with the reciprocating rotation of the filter shaft 62 to achieve a better cleaning purpose; the other stream of water flows to the electric contact liquid level gauge 8. The water flowing into the electric contact liquid level gauge 8 flows into the sewage pipe 24 and merges with the water flowing down from the outer casing 35. In this process, the leachate and the cleaning water accumulate in the outer casing 35 and the water outlet cylinder 332, so that the rotation of the knife holder group and the filter shaft 62 drives the water flow, and also drives the impurities in the leachate to move, so as to better crush and discharge them.

[0091] When water flows through the fourth connecting pipe 74, it flows into the fourth annular water pipe 741 along the fourth connecting pipe 74 and is sprayed out by the fourth nozzle 742 and the fifth nozzle 743 at the same time. The fourth nozzle 742 directly rinses the rotating tool holder group, and the fifth nozzle 743 directly rinses the electric butterfly valve position between the cylinder 1 and the water inlet cylinder 331.

[0092] As the amount of inflowing water increases, the electric contact liquid level gauge 8 displays the water level in the shell 35. If large particles of waste enter the electric contact liquid level gauge 8, the liquid level gauge drain valve 81 can be opened to drain them. Similarly, when blockage occurs in the shell 35, the switch valve 131 on the diversion pipe 130 can also be opened to drain them. In addition, the air in the shell 35 and the outlet pipe 23 is discharged through the second hose 15 and the first hose 12 at the same time, and the air pressure will not affect the water level in the shell 35 and the outlet pipe 23. When the electric contact liquid level gauge 8 displays that the water level reaches a high level, the water supply pipe 7 is closed, and the tool holder group and the filter shaft 62 continue to rotate to crush the residual waste in the water. After rotating and flushing for a while, the electric butterfly valve connected to the cylinder 1, the drain pipe 9 and the drain pipe 211 is opened to discharge the cleaned water.

[0093] If cleaning is needed again, when the electric contact liquid level gauge 8 shows a low water level, close the cylinder 1, the drain pipe 9 and the electric butterfly valve connected to the sewage pipe 24 again, open the water supply pipe 7 to inject water, and repeat the above corresponding steps. Repeat this operation until the cleaning meets the standards. Combined with the first ultrasonic liquid level measuring instrument 2 previously set on the cylinder 1 to monitor the liquid level of the sewage, the circulation status of the leachate can be grasped in real time, so that the device can filter and self-clean simultaneously. The structure is simple and compact, and it is convenient and flexible to use.

[0094] It should be noted that this embodiment is not unique. The connection between the water supply pipe 7 and the four connecting pipes can be equipped with valves according to the needs of use to control the cleaning water supply position, save water and improve cleaning efficiency; in addition, the electric butterfly valve used in this embodiment and the valves in other positions can be equipped with electronic control components and connected to the PLC controller to improve operational efficiency. The content of the above-mentioned prior art will not be repeated here.

[0095] Then, if Figures 25 to 29As shown, after the leachate flows into the leachate tank body 91, the entrained matter in the leachate will settle to the mud outlet trough 911 and fall into the cover body 30 through the opening of the shield. When the sediment reaches a certain volume, the second drive motor 42 is started to drive the connecting disc 33 and the second sleeve 32 to rotate synchronously, that is, the cover body 30 is also driven to rotate synchronously, and the precipitated entrained matter is poured out from the opening position of the cover body. At the same time, it is also necessary to start the first drive motor 41, and the first spiral blade 431 and the second spiral blade 431 push the sediment to move As for the discharge outlet at the lower end of the mud outlet trough 911, since the discharge outlet of the mud outlet trough 911 is in the middle position, the spiral directions of the two spiral blades are set in opposite directions. When rotating, the two spiral blades can gather the precipitated entrained materials to the center, so as to quickly discharge the precipitate and restore the liquid storage volume of the leachate tank body 91, and prevent the leachate from overflowing before reaching the liquid storage volume of the leachate tank body 91. On the one hand, it can protect the environment, and on the other hand, it can ensure the normal operation of the leachate tank body 91 and avoid safety hazards in use.

[0096] It should be noted that if Figure 26 and Figure 27 As shown, the first sealing ring 610, the second sealing ring 620 and the boss 403 can prevent the leakage of leachate from the gap at the installation position, and can play a good sealing role; the lubricating ring 70 is fitted and connected with the connecting cone section 701, which can play a lubricating role during the rotation process, reduce the rotational wear of the first sleeve 31 and the second sleeve 32, extend the service life, and reduce the maintenance cost.

[0097] Finally, if Figure 25 and Figure 26 As shown, the power motor drives the rotating shaft 801 to rotate, and a cavity is formed between two adjacent partitions. As the rotating shaft 801 rotates, the entrained materials discharged from the mud discharge trough 11 are discharged in batches and in an orderly manner through the six partitions 802. While ensuring the slag discharge efficiency, it also facilitates the orderly collection of the discharge materials at the discharge port position of the box body 80.

[0098] like Figure 1 、 Figure 25 、 Figures 30 to 40 As shown, when the leachate level rises to the discharge port 101 of the liquid storage tank, the leachate and the floating objects move toward the discharge port 101 together. Since the floating objects are accumulated, in order to prevent the accumulation from affecting the discharge of the leachate and causing the leachate in the liquid storage tank to overflow from the upper end opening of the liquid storage tank, it is necessary to disperse the floating objects.

[0099] Specifically, if Figure 30 、 Figure 31 、 Figures 37 to 39As shown, the driving motor 232 is started on the PLC controller to drive the support block 233 to move along the axial direction of the guide rod 235, and the first Y-axis moving rail 220 and the second Y-axis moving rail 240 connected thereto are also synchronously moved, wherein, since six first left inclined guide rails 211a and six first right inclined guide rails 212a are arranged on the first Y-axis moving rail 220, six angles α1 are formed between the six first left inclined guide rails 211a and the X-axis of the first Y-axis moving rail 220, and the values of the adjacent two angles α1 are arranged in an arithmetic progression from left to right.

[0100] Similarly, six second left inclined guide rails 214a and six second right inclined guide rails 215a are arranged on the second Y-axis moving rail 240, six angles α2 are formed between the six second left inclined guide rails 214a and the X-axis of the first Y-axis moving rail 220, and the values of the adjacent two angles α2 are arranged in an arithmetic progression from left to right, and six angles β2 are formed between the six second right inclined guide rails 215a and the X-axis of the first Y-axis moving rail 220, and the values of the adjacent two angles β2 are arranged in an arithmetic progression from right to left; at the same time, the first Y-axis guide rail 213 coaxial with the symmetry axis L1 is arranged on the first Y-axis moving rail 220, and the second Y-axis guide rail 216 located directly below the first Y-axis guide rail 213 is arranged on the second Y-axis moving rail 240.

[0101] As shown in Figure 30 , Figure 34 , Figure 35 , Figure 36 , Figure 39 and Figure 40 , the connecting shaft 330 is arranged between the guide rails at the corresponding positions of the first Y-axis moving rail 220 and the second Y-axis moving rail 240, and when the Y-axis moving rail moves linearly along the Y-axis direction, the F Y+ or F Y- force acting on the connecting shaft 330 in the F X+ or F X-The component force in the direction of the Y axis pushes the connecting shaft 330 to move linearly along the X axis, and enables the two side walls of the second side wing 322 to be stuck in the wide groove 312a of the first side wing 312 of the adjacent dredging block 310, forming a clamping action; at the same time, since the angle values ​​of the adjacent α1 and α2 and the angle values ​​of β1 and β2 are all set in equal intervals, the situation where each connecting shaft 330 is blocked due to the difference in moving distance is avoided, and the guide rails at corresponding positions are symmetrically arranged, ensuring the integrity and stability of the movement. As the drive motor 232 drives the two connected Y-axis moving rails to perform linear reciprocating motion along the Y axis, the first side wing 312 and the second side wing 322 set opposite to each other on the two adjacent connecting shafts 330 also perform reciprocating motion. The reciprocating clamping action generated by this can easily disperse the floating objects and prevent them from accumulating.

[0102] Among them, such as Figures 30 to 33 As shown, during the movement of the Y-axis guide rail, since the first Y-axis guide rail 213 is embedded with a first lubricating ring 217, the lower end surface of the cover plate 34 is in contact with the upper end surface of the first lubricating ring 217, and the second left inclined guide rail 214a, the second right inclined guide rail 215a and the second Y-axis guide rail 216 are embedded with a second lubricating ring 218, the upper end groove wall of the annular groove on the connecting shaft 330 is in contact with the upper end surface of the second lubricating ring 218, and the lower end groove wall of the annular groove is in contact with the upper end surface of the second lubricating ring 218. It fits with the lower end surface of the second lubricating ring 218; a third lubricating ring 121 is embedded in the rail groove 120 of the lower fixed rail 100a, and the lower end surface of the connecting shaft 330 fits with 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 fits with the inner wall of the fourth lubricating ring 219, so as to ensure the stability of the connecting shaft 330 in the X-direction movement, while reducing movement wear and extending the service life.

[0103] It should be noted that the inner wall of the fourth lubrication ring 219 and the inner wall of the third lubrication ring 121 are both conical structures. Correspondingly, the outer walls of the upper slider 320b and the lower slider 320a are also adapted to be conical structures. Under the action of gravity, the conical surface fits more stably and the connecting shaft 330 is not prone to movement.

[0104] During use, water is released at the flushing pipe 92 to spray the dredging block 310 to prevent floating objects from remaining. When the liquid level drops back to a position below the plane of the platform 12, the drive motor 232 is turned off. At the same time, if the liquid level of the leachate continues to rise, the second ultrasonic liquid level measuring instrument 93 will send a signal to the connected PLC controller when it detects that the liquid level is too high, and the PLC controller will send a signal to the alarm device to quickly and timely issue an early warning to prevent the leachate from overflowing.

[0105] Among them, the first ultrasonic liquid level measuring instrument 2, the second ultrasonic liquid level measuring instrument 93, the power motor, the drive motor 232, the first drive motor 41 and the second drive motor 42 are all connected to the PLC controller to perform automated and intelligent operation management, which greatly reduces the workload. Since the PLC controller only involves use and operation and does not involve program settings, and the PLC controller is a commonly used device, its specific connection and setting will not be repeated here in the present invention.
