Description

Technical Field

[0001] The invention relates to the field of sludge treatment equipment, in particular to a high-efficiency anti-blocking sludge concentration and dewatering tank. Background Art

[0002] The sludge produced by sewage treatment has a high water content. Due to the nature of water binding to sludge particles, mechanical removal methods have certain limitations. The organic matter content and ash content in the sludge, especially the amount of flocculant added, have a significant impact on the final solid content. Generally speaking, mechanical dehydration can achieve a solid content of 20%-30%, and the resulting sludge is also called mud cake. The mud cake still has a high water content and fluid properties, making its disposal difficult and costly.

[0003] Mechanical dewatering methods include filtration and centrifugation. Filtration involves filtering wet sludge through a filter layer (porous material such as filter cloth or wire mesh), allowing water (filtrate) to permeate the filter layer while the dewatered sludge (filter cake) is retained on top. Centrifugation utilizes the differential centrifugal forces generated by the difference in specific gravity between solids and liquids in the sludge to achieve sludge-water separation. Equipment used for filtration includes vacuum filters, plate and frame filter presses, and belt filters. However, existing plate and frame filter presses are commonly used in the chemical industry, with intermittent sludge feeding and discharge, resulting in low productivity. Manually operated plate and frame filter presses are labor-intensive, requiring manual cleaning and feeding, which is time-consuming and labor-intensive. Furthermore, precise sludge loading is impossible, and cleaning efficiency varies. Consequently, the dewatering rate and quality of sludge cannot be guaranteed or consistent during actual use. Therefore, we have developed a high-efficiency, anti-clogging sludge concentration and dewatering tank. Summary of the Invention

[0020] (3) Beneficial effects

[0021] Compared with the existing technology, the present invention provides a high-efficiency anti-blocking sludge concentration and dewatering tank with the following beneficial effects:

[0022] 1. The high-efficiency anti-blocking sludge concentration and dewatering tank is fixedly connected to the outer wall of the rotating drum with four groups of sludge dewatering frames distributed in a cross shape. The bottom end of the sludge dewatering tank is provided with a rotating drive mechanism connected to the rotating drum, which is used to drive the four groups of sludge dewatering frames to do pause-type circular motion. The corresponding sludge dewatering frames in the sludge dewatering tank are rotated ninety degrees from the bottom of the discharge end of the sludge discharge pipe in sequence, and a filter press dewatering mechanism, a discharge mechanism and a cleaning mechanism are respectively provided. Through the special arrangement of the displacement gear, the center gear and the dewatering transmission gear in the filter press dewatering mechanism in the rotating drive mechanism, the four groups of sludge dewatering frames can be synchronously rotated ninety degrees during the process of one rotation of the center gear, so that the sludge dewatering frame containing the concentrated sludge is displaced to the filter press dewatering machine Below the dewatering pressure plate in the structure, during the rotation of the central gear, only the part of the central gear with the long tooth group can make the circumferential displacement gear rotate, and it stops after rotating ninety degrees. At the same time, the opposite side of the central gear corresponding to the long tooth group is a smooth surface. During the rotation of the circumferential displacement gear, the central gear will not mesh with the dewatering transmission gear in the transmission assembly, that is, the filter press dewatering mechanism will not operate. When the long tooth group on the central gear rotates and does not mesh with the circumferential displacement gear, the short tooth group and the long tooth group on the circumferential displacement gear begin to mesh and transmit with the dewatering transmission gear. That is, when the sludge dewatering frame is stopped, the central gear will drive the dewatering transmission gear to rotate, thereby driving the filter press dewatering mechanism to dewater the sludge.

[0023] Any group of sludge dewatering frames in the dewatering tank can sequentially perform concentrated sludge discharging, mechanical filter pressing dewatering, dewatered mud cake discharging and cleaning operations; four groups of sludge dewatering frames can simultaneously perform concentrated sludge discharging, mechanical filter pressing dewatering, dewatered mud cake discharging and cleaning operations; and each group of sludge dewatering frames is in a pause state when performing different operations, ensuring the rationality of the operations; at the same time, all operations are non-manually automated, saving manpower while also ensuring the synchronization and sameness of each operation step in the concentrated sludge discharging, mechanical filter pressing dewatering, dewatered mud cake discharging and cleaning operations, ensuring that the sludge dewatering efficiency and quality are greatly improved.

[0024] 2. The high-efficiency anti-blocking sludge concentration and dewatering tank has an inclined bottom of the sludge dewatering frame, and the lowest side of the inner wall of the bottom of the sludge dewatering frame is close to the rotating drum; when the concentrated sludge is fed into the sludge dewatering frame, the sludge will gather on the higher side of the sludge dewatering frame. The inclined bottom can make the sludge flow to the lower side to avoid sludge aggregation, and can make the sludge relatively flat in the sludge dewatering frame, which is convenient for subsequent filtration and dehydration of the sludge in the sludge dewatering frame through the dewatering pressure plate.

[0025] 3. The high-efficiency anti-blocking sludge thickening and dewatering tank cooperates with the sealing assembly on the sludge discharge end through the switch trigger components set on the four rotating sludge dewatering frames; the four rotating sludge dewatering frames can cooperate with the sludge discharge end automatically to complete automatic unloading and stop unloading operations, and the four groups of sludge dewatering frames have the same rotation trajectory, so that the operation process of each group of sludge dewatering frames between the discharge end and the sealing assembly is the same, thereby ensuring that the discharge amount of concentrated sludge in the four groups of sludge dewatering frames is the same, and subsequently cooperate with the filter press disengagement mechanism with the same operation to make the mud cake dehydration rate in each group of sludge dewatering frames the same.

[0026] 4. In the high-efficiency anti-clogging sludge thickening and dewatering tank, when the four groups of sludge dewatering frames are rotating, when the switch trigger mechanism on the sludge dewatering frame opens the sealing assembly at the discharge end to discharge the concentrated sludge, the arc-shaped sealing plate will squeeze the reset spring to deform, so that the pressure sensor detects the deformation of the reset spring, thereby transmitting an electrical signal to the water pump, driving the water pump to transmit the water in the water tank to the cleaning nozzle through the water pipe, and the cleaning nozzle is used to clean the sludge dewatering frame after the mud cake is discharged, completing the self-cleaning effect. While achieving the sludge discharge, the next group of sludge dewatering frames to be held in the concentrated sludge are cleaned to ensure that the bottom filter holes of the sludge dewatering frame will not be blocked, thereby ensuring the effect of mechanical filtration and dehydration of the sludge, and improving the anti-clogging performance of the dewatering tank.

[0027] 5. The high-efficiency anti-clogging sludge concentration and dewatering tank is constructed by locating the sewage polymerization tank below the two groups of sludge dewatering frames in an inclined shape, and the end of the sewage polymerization tank close to the filter press dewatering mechanism is the lowest end of the inclination. A sewage pipe is fixedly connected to the corresponding lowest end of the inclination of the sewage polymerization tank. An arc groove through hole is fixed in the middle of the sewage polymerization tank for passing through the vertical shaft connecting the rotating drum and the circumferential displacement gear. The interior of the sewage polymerization tank is connected. When the sludge mechanical filter press dewatering and cleaning operations are performed in the two opposing sludge dewatering frames, the sewage filtered out from the bottom of the sludge dewatering frames is collected in the inclined sewage polymerization tank and discharged through the sewage pipe connected to the lowest end of the sewage polymerization tank. The special design of the sewage polymerization tank facilitates the simultaneous discharge of sewage from the sludge filter press dewatering and the cleaning of the sewage.

[0028] 6. This high-efficiency anti-clogging sludge concentration and dewatering tank has no sludge contacting the holes on the dewatering tank during the dewatering process, and the sludge dewatering frame can be automatically cleaned, which greatly improves the anti-clogging performance of the dewatering tank.

[0029] 7. This high-efficiency anti-blocking sludge thickening and dewatering tank ensures that the sludge will not spill out of the sludge dewatering frame when the concentrated sludge is discharged, by making the width of the sludge dewatering frame greater than the width of the discharge end. At the same time, the arc-shaped chute at the bottom of the concentrated sludge discharge end will gather concentrated sludge during discharge, and the arc-shaped sealing plate that rebounds quickly at the end of discharge can push out the sludge gathered in the arc-shaped chute, and the pushed-out sludge can automatically fall into the sludge dewatering frame, preventing the sludge from dripping and spreading on the inner wall of the dewatering tank.

[0030] 8. This high-efficiency anti-clogging sludge concentration and dewatering tank uses a specially designed vertical moving frame and dewatering transmission gear between the dehydration power reciprocating component and the central gear in the filter press dewatering mechanism, so that the filter press dewatering operation can only be carried out when the sludge dewatering frame stops. The sludge dewatering frame rotation drive source and the filter press dewatering drive source are the same drive source, saving the investment in the drive source. At the same time, dehydration is carried out through pure mechanical transmission. Compared with the existing method of calculating the time and filter press process through precise intelligent instruments, the investment cost of large machines and intelligent machines is saved, and the synchronization of the four groups of sludge dewatering frames when performing different operations is very high.

At the same time, the arc-shaped chute 16 at the bottom of the concentrated sludge discharge end will gather concentrated sludge during discharge, and the arc-shaped sealing plate 17 that rebounds quickly at the end of discharge can push out the sludge gathered in the arc-shaped chute 16, and the pushed-out sludge can automatically fall into the sludge dewatering frame 8 to prevent the sludge from dripping and spreading on the inner wall of the dewatering tank.

[0053] The contact surfaces between the second abutment plate 24 and the arc-shaped abutment plate rod 23 are both inclined surfaces. The outer side surface of the second abutment plate 24 is an arc-shaped surface that can contact the end of the side plate 18. The discharge end surface of the sludge discharge pipe 2, the arc-shaped sealing plate 17, the arc-shaped guide rod 19 and the arc-shaped abutment plate rod 23 are all arc-shaped to fit the sludge dewatering frame 8 to make a circular motion trajectory. The length from the end surface of the side plate 18 to the inner wall of the sludge dewatering tank 1 is greater than the length from the end surface of the first abutment plate 21 to the inner wall of the sludge dewatering tank 1;

[0054] When the sludge dewatering frame 8 located below the discharge end is displaced, the push rod contact 25 at one end of the arc-shaped push plate rod 23 above it will come into contact with the push plate 1 21 on the arc-shaped sealing plate 17, and due to the arc-shaped surface of the push rod contact 25, the push rod contact 25 will slide past the end surface of the push plate 1 21 and squeeze the arc-shaped push plate rod 23 to flip. When the push rod contact 25 slides to the push plate 1 21, the arc-shaped push plate rod 23 returns to its original shape through the torsion spring at the hinge. During the continued displacement of the sludge dewatering frame 8, the push plate 2 24 on the arc-shaped push plate rod 23 will come into contact with the push plate 1 21 again, and drive the arc-shaped sealing plate 17 along the arc-shaped slide groove 16 and the arc-shaped guide rail rod 1 by abutting the push plate 1 21. 9 performs arc displacement, and the concentrated sludge in the concentrated sludge storage tank 3 will be discharged into the sludge dewatering frame 8 through the sludge discharge pipe 2. At the same time, the reset spring 20 will be squeezed during the displacement of the arc-shaped sealing plate 17. When the rod contact 25 at one end of the arc-shaped plate-retaining rod 23 will contact the end face of the side plate 18, since the width of the rod contact 25 is wider than that of the plate 2 24, the arc-shaped plate-retaining rod 23 will be flipped again, and the plate 2 24 and the plate 1 21 will be separated from each other along the inclined surface. At this time, the deformed reset spring 20 can quickly rebound to quickly reset the arc-shaped sealing plate 17, thereby closing the discharge end of the sludge discharge pipe 2 and stopping the discharge of the concentrated sludge.

[0055] The dehydration power reciprocating assembly 14 includes a vertical moving frame 26, a turntable 27, a U-shaped tooth groove 28 and a pressing frame rod 29. A through vertical groove 11 is provided on the sludge dewatering tank 1 at a position corresponding to the sludge discharge pipe 2 at a ninety-degree distance from the discharge end thereof. A gantry 12 is embedded in the vertical groove 11. The inner walls of the side surfaces of the gantry 12 close to each other are provided with T-shaped sliding slots 31. Both sides of the vertical moving frame 26 are provided with integrated T-shaped connecting strips 32 adapted to the arc-shaped plate rod 23. The vertical moving frame 26 is connected to the gantry 12 for sliding up and down through the T-shaped connecting strips 32. Two sets of bent connecting rods 30 are fixedly installed on the top of the vertical moving frame 26, and the vertical moving frame 2 6 is fixedly connected to the dewatering pressure plate 13 located above the sludge dewatering frame 8 through a bent connecting rod 30. A horizontal base plate is fixedly installed on the side of the gantry 12 facing away from the rotating drum 7, and a turntable 27 located inside the gantry 12 is rotatably installed at the center of the horizontal base plate, and the outer wall of the end surface of the turntable 27 is in contact with the vertical moving frame 26. Mutually symmetrical U-shaped tooth grooves 28 are provided on both sides of the vertical moving frame 26 corresponding to the area where the turntable 27 is in contact. The convex end surface and the concave end surface of the U-shaped tooth groove 28 are both semicircular surfaces. Six pressure frame rods 29 that can be engaged with the U-shaped tooth groove 28 are fixedly installed along the side of the turntable 27, and the six pressure frame rods 29 are arranged in an arc shape.

[0056] The transmission assembly includes a dehydration transmission gear 33, a rotating shaft 34, a belt 36 and a belt pulley 37. A corresponding stand 35 is provided on the inner wall of the bottom of the sludge dehydration tank 1. A horizontal rotating shaft 34 is rotatably installed on the stand 35. The dehydration transmission gear 33 is fixedly installed on one end of the rotating shaft 34 close to the center gear 5, and the bottom of the dehydration transmission gear 33 is vertically meshed with the long tooth group 10 and the short tooth group 9 on the center gear 5, and the number of teeth in a circle on the dehydration transmission gear 33 is the same as the number of teeth on the center gear 5. The end of the rotating shaft 34 away from the dehydration transmission gear 33 extends to the outside of the gantry 12 and is fixedly connected to the belt pulley 37, and a belt pulley 37 fixedly connected to the turntable 27 is also fixedly installed on the outer wall of the horizontal base plate away from the turntable 27. The upper and lower sets of belt pulleys 37 are sleeved in the middle. A belt 36 is connected. During one rotation of the central gear 5, the four groups of sludge dewatering frames 8 can be synchronously rotated ninety degrees, so that the sludge dewatering frame 8 containing concentrated sludge is displaced to the bottom of the dewatering pressure plate 13 in the filter press dewatering mechanism. During the rotation of the central gear 5, only the part of the central gear 5 with the long tooth group 10 can rotate the circumferential displacement gear 4, and it stops after rotating ninety degrees. At the same time, the opposite side of the central gear 5 corresponding to the long tooth group 10 is a smooth surface. During the rotation of the circumferential displacement gear 4, the central gear 5 will not mesh with the dewatering transmission gear 33 in the transmission assembly, that is, the filter press dewatering mechanism will not operate. When the long tooth group 10 on the central gear 5 rotates and does not mesh with the circumferential displacement gear 4, the short tooth group 9 on the circumferential displacement gear 4 The long tooth group 10 begins to mesh with the dehydration transmission gear 33 for transmission, that is, when the sludge dehydration frame 8 stops, the central gear 5 will drive the dehydration transmission gear 33 to rotate. At this time, the dehydration transmission gear 33 will drive the belt pulley 37 to rotate through the rotating shaft 34, and drive the belt pulley 37 on the back of the gantry 12 to rotate through the belt 36, thereby causing the turntable 27 to rotate. Since the number of gear teeth on the dehydration transmission gear 33 is the same as the number of gear teeth on the central gear 5, when the central gear 5 rotates to the process of the long tooth group 10 and the circumferential displacement gear 4 being meshed again, the turntable 27 can be caused to rotate one circle. During the rotation of the turntable 27, the multiple groups of U-shaped tooth grooves 28 thereon will make a downward arc displacement and then an upward arc displacement, that is, multiple groups of U-shaped tooth grooves 28 will first press down the U-shaped tooth groove 28 on one side of the vertical moving frame 26 in sequence, and then lift up the U-shaped tooth groove 28 on the other side of the vertical moving frame 26, so that the vertical moving frame 26 will first drive the dewatering pressure plate 13 to press down on the sludge dewatering frame 8 containing concentrated sludge through the bent connecting rod 30, and then automatically move up and reset. During the upward process, the dewatering pressure plate 13 will cooperate with the bottom of the sludge dewatering frame 8 to complete the mechanical filtration and dehydration operation of the sludge, and the concentrated sludge is dehydrated into a mud cake. Although the dewatering tank adopts the traditional mechanical filtration and dehydration, the specially designed vertical moving frame 26 and dehydration transmission gear 33 between the dehydration power reciprocating assembly 14 and the central gear 5 in the filtration and dehydration mechanism of the dewatering tank can make the filtration and dehydration operation only operate when the sludge dewatering frame 8 stops.The sludge dewatering frame 8 uses the same drive source for rotation and filter pressing, saving investment in drive sources. Dewatering is performed through pure mechanical transmission, saving investment in large and intelligent machines compared to the existing method of calculating time and filter pressing processes using precise intelligent instruments. Furthermore, the synchronization of the four groups of sludge dewatering frames 8 during different operations is very high.

[0057] The cleaning mechanism includes a cleaning nozzle 40, a water pipe 41, a water pump 42 and a water tank 43. A water tank 43 is installed on the outer wall of the side of the sludge dewatering tank 1. The water pump 42 is fixed on the water tank 43, and the output end of the water pump 42 is fixedly connected to the water pipe 41 extending into the interior of the sludge dewatering tank 1. The water pipe 41 is located in the internal port of the sludge dewatering tank 1 and is fixedly connected to two groups of cleaning nozzles 40. The two groups of cleaning nozzles 40 are located above the sludge dewatering frame 8 on the opposite side of the filter press dewatering mechanism. The deformable return spring 20 in the sealing assembly is electrically connected to the electrical contact of the pressure sensor, and the pressure sensor is electrically connected to the switch of the water pump 42; during the rotation of the four groups of sludge dewatering frames 8 In the process, when the switch trigger mechanism on the sludge dewatering frame 8 opens the sealing assembly at the discharge end to discharge the concentrated sludge, the arc-shaped sealing plate 17 will squeeze the reset spring 20 to deform, so that the pressure sensor detects the deformation of the reset spring 20, thereby transmitting an electrical signal to the water pump 42, driving the water pump 42 to transmit the water in the water tank 43 to the cleaning nozzle 40 through the water pipe 41, and the sludge dewatering frame 8 after the mud cake is discharged is cleaned by the cleaning nozzle 40. While achieving the sludge discharge, the next group of sludge dewatering frames 8 to be held in the concentrated sludge are cleaned to ensure that the bottom filter holes of the sludge dewatering frame 8 will not be blocked, thereby ensuring the effect of mechanical filtration and dehydration of the sludge.

[0058] The sewage polymerization tank 15 is located below the two groups of sludge dewatering frames 8 and is inclined, and the end of the sewage polymerization tank 15 close to the filter press dewatering mechanism is the lowest end of the inclination. The sewage polymerization tank 15 is fixedly connected to the corresponding lowest end of the inclination with a sewage pipe 38. An arc groove through hole 39 is fixed in the middle of the sewage polymerization tank 15 for passing through the vertical shaft connected between the rotating drum 7 and the circumferential displacement gear 4. The interior of the sewage polymerization tank 15 is connected; in the above rotation process of completing sludge dewatering by taking a certain group of sludge dewatering frames 8 as an example, the other three groups of sludge dewatering frames 8 are simultaneously performing concentrated sludge discharge, mechanical filter press dewatering, dewatered mud cake discharge and cleaning operations, and when the sludge mechanical filter press dewatering and the sludge dewatering frame 8 are performed in the two opposing groups of sludge dewatering frames 8, the sewage filtered out from the bottom of the sludge dewatering frame 8 is collected in the inclined sewage polymerization tank 15 and discharged through the sewage pipe 38 connected to the lowest end of the sewage polymerization tank 15.
