Description

TECHNICAL FIELD

[0002] The leachate in the waste incineration power plant is mainly derived from the moisture of the waste, and part of the rainwater in the landfill plant, and the kitchen waste is mainly wastewater from catering enterprises, which is usually treated together with the waste. The waste leachate is a kind of high-concentration organic wastewater with complex composition. However, in the current filtration process of leachate, various types of garbage from the leachate are blocked, so that the filtration system of the leachate is often in a blocked and paralyzed state, causing frequent overflow of the leachate, causing severe pollution to the site, seriously affecting normal production and the site environment. The main reason is the static grid in the leachate filter. The floating material in the filtration process of the leachate filter blocks the grid, causing the filter to be paralyzed. At the same time, after the filtration treatment, a large amount of precipitate and a large amount of floating waste will be generated in the wastewater tank. If these precipitates are not treated in time, the volume of the wastewater tank will be reduced, causing the wastewater tank to overflow before reaching the use volume. At the same time of overflow, the floating material will also be taken out, which not only affects the environment, but also causes safety hazards. SUMMARY

[0081] Similarly, the second Y-axis moving rail 240 is further provided with a second Y-axis guide rail 216 located directly below the first Y-axis guide rail 213, and the connecting shaft 330 of the middle dredging member 300c of the plurality of dredging members 300 penetrates into the second Y-axis guide rail 216 and can be slidably matched therewith. A ring groove is arranged at the position of the connecting shaft 330 corresponding to the second left inclined guide rail 214a, the second right inclined guide rail 215a and the second Y-axis guide rail 216, and a second lubricating ring 218 is arranged in the second left inclined guide rail 214a, the second right inclined guide rail 215a and the second Y-axis guide rail 216, the upper end groove wall of the ring groove is attached to the upper end surface of the second lubricating ring 218, and the lower end groove wall of the ring groove is attached to the lower end surface of the second lubricating ring 218.

[0082] In addition, a third lubricating ring 121 is arranged in the rail groove 120 of the lower fixed rail 100a, the lower sliding block 320a extends into the rail groove 120 and is attached to the inner side wall of the third lubricating ring 121, and the lower end surface of the connecting shaft 330 is attached to the upper end surface of the third lubricating ring 121.

[0083] The flushing pipe 92 is arranged in the reservoir 91, and the water outlet of the flushing pipe 92 is directed to the position of the dredging block 310, so as to flush the dredging block 310 and prevent floating objects from being accumulated on the dredging block 310; the second ultrasonic liquid level meter 93 connected with the PLC controller is arranged in the reservoir 91, so as to monitor the liquid level of the percolate in the reservoir 91, and adjust the rotating speed of the power motor and the rotating shaft 801, so as to timely discharge the percolate at the position of the box body 80 and reduce the liquid level of the percolate.

[0084] The use principle of the present application is as follows:

[0085] As shown in Figures 1 to 4 , the first ultrasonic liquid level meter 2 connected with the PLC controller and the driving motor 4 are arranged on the barrel body 1; when the height of the accumulated objects is low, the reflection time of the sound beam is long, the PLC controller does not send the starting instruction to the driving motor 4, and the percolate is automatically discharged along the barrel body 1; when the height of the accumulated objects is high, the reflection time of the sound beam is short, the first ultrasonic liquid level meter 2 sends the signal to the PLC controller, and the PLC controller sends the starting instruction to the driving motor 4, so that the screw propeller drives the shaftless spiral blade 3 to rotate and drives the accumulated objects to be discharged and moved to the reservoir 91, so as to timely dredge the barrel body 1; when the height of the accumulated objects is reduced to the appropriate height, the reflection time of the sound beam is long again, the PLC controller sends the shutdown instruction to the driving motor 4, the screw propeller is closed, and the shaftless spiral blade 3 stops rotating, and the percolate is continuously automatically discharged along the barrel body 1.

[0086] It should be noted that the PLC controller only selects the minimum value of the reflection time of the two first ultrasonic liquid level meters 2, that is, the reflection time is the shortest and reaches the accumulated height, so as to send the signal to the PLC controller, and the PLC controller sends the starting instruction to the driving motor 4; when the height of the accumulated objects is reduced, the reflection time of the two first ultrasonic liquid level meters 2 is restored to the longer value, so as to send the signal to the PLC controller, and the PLC controller sends the shutdown instruction 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 on the shaft core.

[0087] As shown in Figure 1 , Figure 2 , Figures 5 to 17As shown, after the leachate enters the shell 35 through the water inlet cylinder 331, the transmission 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 in 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 rotating direction of the rotating shaft 14, the outer circle of the sewage away from the rotating shaft 14 will reduce the flow rate, and the rotating speed of the rotating shaft 14 will not change, that is, the cutting speed of the twelve blades will not change. The speed difference generated thereby can fully crush the waste, and the leachate meeting the filtering standard can flow out after filtering. It should be noted that nine blades 333 are equally and spirally arranged 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 avoid blockage of leachate discharge.

[0088] At the same time, as shown in Figure 1 、 Figure 2 、 Figures 18 to 20 The electric top cylinder 66 is started to move reciprocally, and the first guide block 651 is also moved reciprocally in the horizontal direction synchronously. One side of the first guide plate 651 is engaged and connected with the transmission gear 63, and the transmission gear 63 is engaged and connected with two groups of driven gear sets (not marked) on one side, and is engaged and connected with the second guide plate 652 on the other side. Each driven gear set includes seven driven gears 61 arranged side by side and engaged in sequence, that is, the second guide plate 652 and the two groups of driven gears 61 also move reciprocally with the transmission gear 63. The reciprocating rotation of the driven gear 61 drives the vertically installed filter shaft 62 to reciprocate. In order to avoid jamming, the reciprocating frequency should be increased, which requires adjusting the extension frequency of the electric top cylinder 66. In this way, the reciprocating rotation of the filter shaft 62 forms a spiral flow in the gap between the adjacent two filter shafts 62, which can form a surging flow in the gap and accelerate the leachate to pass through quickly. If large impurities that are missed in the crushing process move to the gap, it is not easy to cause jamming in a short stroke range, and at the same time, it can quickly switch to reverse rotation to take out the larger impurities in the opposite direction, avoiding the blockage of the gap between the filter shafts 62.

[0089] When cleaning is needed, as shown in Figure 2 、 Figure 18 、 Figures 21 to 24As shown, first close the electric butterfly valve (not shown) at the position of the cylinder 1 and the drain pipe 9, open the transmission motor 352 and the electric top cylinder 66, the tool holder group rotates in one direction, the filter shaft 62 rotates back and forth, then water is supplied from the water supply pipe 7, when the water flows through the first connecting pipe 71, it is divided, flows into the first annular water pipe 711 arranged in the drain pipe 9 along the first connecting pipe 71, and is sprayed from the seven first spray heads 712, to clean the residues at the position of the drain pipe 9; when the water flows through the second connecting pipe 72, it is divided into the second annular water pipe 721 arranged outside the drain pipe 24, and is sprayed from the second spray head 722 extending into the drain pipe 24, to clean the residues in the drain pipe 24 and flow to the drain pipe 9 for discharge.

[0090] In sequence, when the water flows through the third connecting pipe 73, it is divided, and then flows into the third annular water pipe 732 arranged in the water outlet cylinder 332 along the third connecting pipe 73, and is sprayed from the third spray head 733, the water outlets of the third spray head 733 are all arranged obliquely towards the center line of the third annular water pipe 732, that is, the water outlet direction is obliquely downward towards the filter shaft 62, the water sprayed from the third spray head 733 cooperates with the reciprocating rotation of the filter shaft 62, to achieve better cleaning purpose; the other water flows to the electric contact liquid level meter 8, the water flowing into the electric contact liquid level meter 8 flows into the drain pipe 24 and combines with the water flowing down from the shell 30, in this process, the leachate and the cleaning water accumulate in the shell 35 and the water outlet cylinder 332, so that the rotation of the tool holder group and the filter shaft 62 drives the water flow and the impurities in the leachate to move, to better stir and discharge.

[0091] When the 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 from the fourth spray head 742 and the fifth spray head 743 at the same time, the fourth spray head 742 directly washes the rotating tool holder group, and the fifth spray head 743 directly washes the position of the electric butterfly valve between the cylinder 1 and the water inlet cylinder 331.

[0092] With the increase of the inflow water, the electric contact liquid level meter 8 displays the water level in the shell 35, if large particle waste enters the electric contact liquid level meter 8, the liquid level meter drain valve 81 can be opened for removal, similarly, when the shell 30 is blocked, the switch valve 131 on the flow guide pipe 130 can be opened for removal treatment, in addition, the air in the shell 35 and the water outlet pipe 23 is discharged through the second hose 15 and the first hose 12 at the same time, so that the water level in the shell 35 and the water outlet pipe 23 is not affected by air pressure, when the electric contact liquid level meter 8 displays the water level to the high position, the water supply pipe 7 is closed, the tool holder group and the filter shaft 62 continue to rotate to stir the residual waste in the water, after a period of rotation and washing, the electric butterfly valves at the positions of the cylinder 1, the drain pipe 9 and the drain pipe 24 are opened, to discharge the cleaned water.

[0093] If further cleaning is needed, when the electric contact liquid level meter 8 shows low water level, close the electric butterfly valve connected to the cylinder 1, the drain pipe 9 position and the blowdown pipe 24 again, and open the water supply pipe 7 to fill water, and repeat the above corresponding steps, and so on until the cleaning is up to standard. The first ultrasonic liquid level meter 2 set on the cylinder 1 monitors the liquid level of the wastewater, and the flow state of the leachate is mastered in real time, so that the filtering and self-cleaning of the device are carried out synchronously, and the structure is simple and compact, and convenient and flexible to use.

[0094] It should be noted that the present embodiment is not unique, and the connection between the water supply pipe 7 and the four connecting pipes can be equipped with a valve according to the needs of use, so as to control the cleaning water supply position, save water and improve the cleaning efficiency; in addition, the electric butterfly valve and other valves in the present embodiment can be equipped with an electric control component and connected with a PLC controller for use, so as to improve the operation efficiency, and the contents of the above prior art will not be repeated.

[0095] Next, as shown in Figures 25 to 29 , after the leachate flows into the liquid storage tank 91, the entrained matter in the leachate will be deposited into the mud outlet chute 911 and fall into the cover body 30 through the opening of the baffle, and when the deposited entrained matter 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 also rotates synchronously, and at the same time, the first drive motor 41 is started, and the first spiral blade 431 and the second spiral blade 431 push the deposited matter to the discharge outlet at the lower end of the mud outlet chute 911. Since the discharge outlet of the mud outlet chute 911 is at the middle position, the spiral directions of the two spiral blades are set in opposite directions, and when rotating, the two spiral blades can realize the purpose of gathering the deposited entrained matter in the middle, so as to quickly discharge the deposited matter and restore the liquid storage volume of the liquid storage tank 91, prevent the leachate from overflowing before reaching the liquid storage volume of the liquid storage tank 91, on the one hand, protect the environment, and on the other hand, ensure the normal operation of the liquid storage tank 91 and avoid safety hazards in use.

[0096] It should be noted that, as shown in Figure 26 and Figure 27 , the first sealing ring 610, the second sealing ring 620 and the boss 403 can prevent the leachate from seeping out from the gap at the installation position, and can play a good sealing effect; the lubricating ring 70 is connected with the connecting cone segment 701, which can play a lubricating role during rotation, reduce the rotating wear of the first sleeve 31 and the second sleeve 32, prolong the service life, and reduce the maintenance cost.

[0097] Finally, as shown in Figure 25 and Figure 26As shown, the power motor is arranged to drive the rotating shaft 801 to rotate, and a cavity is formed between two adjacent partitions. With the rotation of the rotating shaft 801, the entrained material discharged from the mud outlet 11 is discharged in batches and in order through the six partitions 802, which not only ensures the efficiency of the slag discharge, but also facilitates the orderly collection of the discharged material at the discharge port of the box body 80.

[0098] As shown in Figure 1 , Figure 25 , Figures 30 to 40 When the leachate level rises to the position of the discharge port 101 of the storage tank 91, the leachate moves to the discharge port together with the floating material. Since the floating material is accumulated, in order to avoid the accumulation affecting the discharge of the leachate and causing the leachate in the storage tank 91 to overflow from the upper opening of the storage tank 91, it is necessary to perform the operation of scattering the floating material.

[0099] Specifically, as shown in Figure 30 , Figures 31 , Figures 37 to 39 The driving motor 232 is started on the PLC controller to drive the support block 233 to move in 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 also move synchronously. 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 gradually increase from left to right in equal difference; six angles β1 are formed between the six first right inclined guide rails 212a and the X-axis of the first Y-axis moving rail 220, and the values of the adjacent two angles β1 gradually increase from right to left in equal difference.

[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 gradually increase from left to right in equal difference, 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 gradually increase from right to left in equal difference; 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 andFigure 40 As shown, connecting shafts 330 are installed between the guide rails at corresponding positions on the first Y-axis moving rail 220 and the second Y-axis moving rail 240. When the Y-axis moving rail moves linearly along the Y-axis direction, the force generated on the connecting shaft 330 is... Y+ To or F Y- A directional force will produce F X+ To or F X- The force component in the X-axis propels the connecting shaft 330 to move linearly along the X-axis, and allows the two side walls of the second side wing 322 to engage in the wide groove 312a of the first side wing 312 of the adjacent unblocking block 310, forming a clamping action. At the same time, since the included angles of adjacent α1 and α2 and β1 and β2 are set at equal intervals, the obstruction caused by the difference in the moving distance of each connecting shaft 330 is avoided. Moreover, the guide rails at the 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 move linearly back and forth 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 move back and forth. The resulting reciprocating clamping action can conveniently disperse the floating objects and prevent the floating objects 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 equipped with a first lubricating ring 217, the lower end face of the cover plate 34 is in contact with the upper end face of the first lubricating ring 217. The second left inclined guide rail 214a, the second right inclined guide rail 215a, and the second Y-axis guide rail 216 are all equipped with second lubricating rings 218. The upper end wall of the annular groove on the connecting shaft 330 is in contact with the upper end face of the second lubricating ring 218, and the lower end wall of the annular groove... The lower end face of the connecting shaft 330 is in contact with the lower end face 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 face of the connecting shaft 330 is in contact with the upper end face 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 in contact with the inner wall of the fourth lubricating ring 219. This ensures the smoothness of the connecting shaft 330 in the X direction, while reducing wear and extending its service life.

[0103] It should be noted that the inner walls of the fourth lubrication ring 219 and 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 surfaces fit more stably, and the connecting shaft 330 is less likely to move.

[0104] In use, the water spray is positioned at the position of the flushing pipe 92 and the block 310 is positioned at the position of the water spray, so as to prevent the floating residues, and the driving motor 232 is closed when the liquid surface falls below the position of the platform 12; meanwhile, when the liquid surface of the percolation liquid continuously rises and the second ultrasonic liquid level meter 93 detects that the liquid surface is too high, a signal is sent to the connected PLC controller, and the PLC controller sends a signal to the alarm device, so as to give a quick and timely early warning and prevent the percolation liquid from overflowing.

[0105] The first ultrasonic liquid level meter 2, the second ultrasonic liquid level meter 93, the power motor, the driving motor 232, the first driving motor 41 and the second driving motor 42 are all connected with the PLC controller, so that the operation management is automatic and intelligent, and the working strength is greatly reduced. Since the PLC controller only involves the use control and does not involve the program setting, and the PLC controller is a commonly used device, the specific connection and setting will not be described herein.
