Description

Technical Field

[0001] This invention relates to the field of sludge dewatering and solidification technology, and more specifically, to a municipal environmental sludge dewatering and solidification device and method. Background Technology

[0002] Silt refers to fine-grained soil containing organic matter that is deposited in still or slow-flowing water environments. It is generally found in river channels. Excessive silt accumulation in river channels can lead to shallower riverbeds and reduced water storage, thereby deteriorating water quality and damaging the aquatic environment. Therefore, when there is excessive silt accumulation in the riverbed, it is necessary to use silt dewatering and solidification devices to treat it.

[0003] In existing methods, solidification powder needs to be added to the sludge after dewatering. However, the feed inlet of the solidification powder is usually quite large, and the powder is easily spilled into the air during feeding, resulting in waste. In addition, the existing methods for dewatering sludge involve filtering it through a screen, but the sludge has poor fluidity during filtration, which affects the dewatering effect. Therefore, we propose a sludge dewatering and solidification device. Summary of the Invention

[0014] According to another aspect of the present invention, a method for dewatering and solidifying municipal environmental sludge is provided.

[0015] Includes the following steps:

[0016] The sludge is fed into the sludge feed hopper and enters the lower semi-circular trough;

[0017] The drive unit operates, and the drive unit drives the sludge drive wheel to rotate under the drive of the auxiliary power unit. The sludge drive wheel will drive the incoming sludge to roll and roll it onto the discharge platform. The sludge then slides onto the side fault push column along the inclined surface of the discharge platform.

[0018] The drive unit drives multiple fault-push columns to slide up and down together. When the fault-push columns push upward, the tilt angle of the top surface is parallel to the top surface of the adjacent fixed ladder plate on the side, which causes the fault-push columns to push the falling sludge upward. Under the upward push, the sewage contained in the sludge flows down through the water outlet channel and enters the inclined filter plate below for further filtration.

[0019] The overflowing wastewater undergoes multiple filtrations through the first activated carbon filter plate below.

[0020] The filtered wastewater is then discharged from the wastewater outlet.

[0021] The filtered sludge is pushed forward segment by segment by the fault pusher column. After multiple pushes, the wastewater contained in it is filtered out, and the remaining sludge is pushed to the first discharge inlet and enters the first disc, and is then conveyed downward through the upper through hole in the middle.

[0022] Once the drive motor starts running, it drives the central gear, which in turn drives the side gear to rotate. The side gear then drives the threaded lifting rod, causing the threaded lifting rod to move up and down.

[0023] The threaded lifting rod drives the second disc to move up and down reciprocally. The distance between the second disc and the first disc will change continuously. By changing the distance, the sludge that descends along the trajectory is compressed and stretched, thus achieving a better sludge extraction effect.

[0024] The sludge inside the left cavity is compressed by the compression motion generated by the compression component and finally discharged from the sludge outlet.

[0025] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0026] 1. This device features a sludge pushing unit located below the sludge feeding channel. During operation, the sludge pushing unit carries the incoming sludge and its contained wastewater, causing them to roll and tumble. This rolling and tumbling process conveys the sludge to one side, preventing it from clogging and accumulating at the feeding channel. Then, the sludge pushing unit on one side pushes the sludge and wastewater upwards in a step-by-step, discontinuous manner. During this process, the wastewater is drained out, while the water flows downwards through the outlet channel. The remaining sludge is then pushed step-by-step into the left cavity by the discontinuous pushing column. There, it is compressed by the compression components in the left cavity, effectively achieving the dewatering effect of the sludge.

[0027] 2. When the inlet ring of the curing powder is large, it can be adjusted by the control mechanism below to adjust the contact surface at the opening. When the diameter of the inlet ring changes during the curing powder entry process, the entering curing powder is rolled into the lower part by the limit wheel of the spiral, so that it is not easy to overflow into the air.

[0028] 3. When the compression component is in compression motion, it will drive the incoming sludge to be compressed, which improves sludge treatment, facilitates the secondary use of sludge, and has a good environmental protection effect. It avoids the secondary waste caused by directly discharging sludge into the environment with sewage, and avoids the burden on the environment. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] According to embodiments of the present invention, a device and method for dewatering and solidifying municipal environmental sludge are provided, such as... Figures 1 to 5 As shown, where,

[0040] This invention provides a municipal environmental sludge dewatering and solidification device, including a treatment box 1. A protruding portion 2 is located on the upper right side of the treatment box 1, and a sludge feed funnel 3 is located at the top of the protruding portion 2. A solidification powder inlet 4 is located on the top of the treatment box 1 near the sludge feed funnel 3. A sludge pushing part is located inside the treatment box 1 at the protruding portion, and an auxiliary power unit is connected to the sludge pushing part. The auxiliary power unit is located outside the treatment box 1. A longitudinal partition 5 is provided inside the treatment box 1, dividing the interior of the treatment box 1 into a left cavity and a right cavity. A solidification powder inlet 4 is located on one side of the bottom of the right cavity. The system includes a wastewater outlet 6, an inclined filter plate 7 at the lower part of the right cavity, a sludge cross-section refining section at the top of the inclined filter plate 7, and a first discharge inclined port 8 on the left side of the sludge cross-section refining section above the partition 5. The sludge cross-section refining section includes several fixed ladder plates 9, each with a cross-section push column 10 on its right side. The number of fixed ladder plates 9 matches the number of cross-section push columns 10, and both sides of the fixed ladder plates 9 are fixed to the inner wall of the treatment tank 1. The fixed ladder plates 9 and the cross-section push columns 10 are in close contact, and both the cross-section push columns 10 and the fixed ladder plates 9 form a... A stepped design is used, where several stepped push columns 10 move upwards or downwards simultaneously when pushed. When they move upwards simultaneously, their top surfaces are on the same horizontal plane as the top surface of the fixed step plate 9 on the adjacent side. A water outlet channel 11 is provided on the top right side of the stepped push column 10, and a filter screen 12 is provided on the top of the water outlet channel 11. A support plate 13 is provided at the bottom of the stepped push column 10, and a drive unit is provided at the bottom of the support plate 13, which is connected to an auxiliary power unit. Below the solidified powder inlet 4, on the top wall inside the processing box 1, there is a metering mechanism, which includes several... The spiral limiting wheel 14 is equipped with a connecting component, which is driven by the cylinder 15 and the air rod 16. A compression component is provided at the top of the left cavity. The lower part of the partition 5 is located at the left end of the inclined filter plate 7 and has a second discharge outlet 17. A sludge outlet 18 is provided on one side of the bottom of the left cavity. An inspection door is provided on the treatment box 1 to facilitate the inspection and replacement of the internal structure of the treatment box 1. Multiple support legs can be provided on the bottom of the treatment box 1, and universal wheels can be provided on the support legs. The universal wheels are equipped with locks to facilitate the movement of the device.

[0041] The partition 5 has an adsorption plate 19 on its left side, which is made of elastic material. When the second disc 65 moves up and down, the space between the second disc 65 and the first disc 68 is compressed, causing the sludge inside to be squeezed outwards and impact the adsorption plate 19 on the side. The adsorption plate 19 deforms under pressure, changing the internal contact surface and increasing the compressibility between the sludge particles. This prevents the sludge from being discharged due to excessive internal water content, thus increasing the reuse rate. In addition, the adsorption plate 19 can adsorb pollutants contained in the sludge. The lower part of the adsorption plate 19, located at the second discharge inclined port 17, has a discharge port 20. 20 is connected to the second discharge inclined port 17. The top of the adsorption plate 19 is provided with an inclined surface that slopes downwards and to the left of the cavity. The bottom of the sludge feed funnel 3 is located inside the protruding part 2 and is provided with a feed channel 21. The feed channel 21 is located above the sludge pushing part and is provided above the sludge drive wheel 26. The feed channel 21 is a straight channel. When the sludge enters the lower semi-circular groove 22 from the feed channel 21, the feeding time and path are increased. In this way, the sludge will play a certain buffering role during the falling process and will not be directly subjected to the force on the lower semi-circular groove 22, thus avoiding the phenomenon of sludge overflow. The lower semi-circular groove 22 is provided below the sludge pushing part. A material discharge platform 23 is provided on the left side of the 2. A partition 24 is provided at the bottom of the material discharge platform 23. The partition 24 and the inner wall of the treatment box 1 form a compartment. The drive unit is located in the compartment. A first activated carbon filter plate 25 is provided below the inclined filter plate 7. The sludge pushing unit includes a sludge driving wheel 26. A shaft is inserted through the middle of the sludge driving wheel 26. The shaft passes through the protruding part 2. Several pushing grooves 27 are provided on the side of the sludge driving wheel 26. One end of the shaft is connected to the auxiliary power unit. The auxiliary power unit includes a pulley 28 located on the outer end of the shaft. A set of outer support plates 29 is provided on one side of the right side of the protruding part 2. A rotating shaft 30 is transversely inserted between the outer support plates 29. The two sides of the rotating shaft 30 are located on the outer support plates 29. On the left side of plate 1 29, pulley 31 and pulley 32 are respectively provided. Pulley 31 is connected to pulley 4 28 through belt 2 33. On the right side of the processing box 1, near the center, there is an outer support plate 2 34. On the left side of the outer support plate 2 34, there is a pulley 2 35.

The rotating shaft 3 40 passes through the processing box 1 and is connected to the drive unit.

[0042] Additionally, the drive unit includes a second motor 41, with a support base 42 at its bottom. The bottom of the support base 42 is fixed to the inclined filter plate 7. An output shaft is connected to the output end of the second motor 41, and a pulley 43 is provided at the end of the output shaft away from the second motor 41. It also includes a third fixing plate 44, the top of which is fixed to one side of the bottom of the support plate 13. A set of mounting plates 45 is provided at the bottom of the third fixing plate 44, with a connecting member between the mounting plates 45. A drive plate 47 is mounted on the connecting member, and the other end of the drive plate 47... An eccentric wheel 48 is provided, and the inner end of a shaft 3 40 is connected to the middle of the side of the eccentric wheel 48. A pulley 6 49 is fitted on the side of the shaft 3 40 near the eccentric wheel 48. The pulley 6 49 is connected to the pulley 5 43 via a belt 3 50. The connecting components include several sets of limiting blocks 51. A clamping block 52 is provided between any set of limiting blocks 51. The inner clamping groove of the clamping block 52 is movably connected to the spiral limiting wheel 14. A drive disc 53 is provided at the outer end of the clamping block 52. A column 54 is provided on the top of the drive disc 53. The top of drive 4 is fixed to the top of the processing box 1. Each of the two adjacent drive discs 53 has a drive rod 1 55 and a drive rod 2 56 on one side of its bottom. The drive rod 1 55 and the drive rod 2 56 form a V-shaped structure. The V-shaped connection end is connected to the side end of the corresponding drive disc 53. The spiral limiting wheel 14 is movably connected to the clamping block 52. When the spiral limiting wheel 14 is subjected to external force, it will rotate. When rotating, the spiral structure on the surface will roll the solidified powder entering from above downwards, causing the solidified powder inlet 4 to be limited below. The conveying force will be greater than that above. In this way, the phenomenon of solidified powder overflow caused by the size of the ring opening will be effectively avoided, protecting the environment and reducing secondary pollution. Another drive disc 53 has a drive rod 3 57 on one side of its bottom. The drive rod 3 57 is connected to the adjacent drive rod 1 55 and the other two drive rods 2 56 by connecting rods 70. The end of the air rod 16 away from the cylinder 15 is connected to the end of the adjacent drive rod 1 55.

[0043] In addition, the compression component includes a motor 59, which is mounted on the top side of the processing box 1. The output end of the motor 59 is connected to a connecting shaft 60, which passes through the processing box 1. A central gear 61 is located at the bottom of the connecting shaft 60, and a fixed plate 62 is mounted on the connecting shaft 60. The top of the fixed plate 62 is fixed to the inner top wall of the processing box 1. Several sleeves 63 are located around the top periphery of the fixed plate 62, passing through the processing box 1. A threaded lifting rod 64 is inserted inside each sleeve 63. The bottom of the lifting rod 64 is provided with a second disc 65, the middle of the second disc 65 is provided with a lower through hole 66, and the top side of the lower through hole 66 is provided with an upper protruding ring 67 on the top periphery of the second disc 65; the threaded lifting rod 64 is provided with a first disc 68, the middle of the first disc 68 is provided with an upper through hole 69, the top side of the upper through hole 69 is provided with a lower protruding ring 46 on the top periphery of the first disc 68, and the upper part of the threaded lifting rod 64 is provided with a side gear 58 that meshes with the middle gear 61 on the bottom side of the fixed disc 62.

[0044] On the other hand, a method for dewatering and solidifying municipal environmental sludge includes the following steps:

[0045] S101: The sludge is fed into the sludge feed hopper 3 and enters the lower semi-circular trough 22;

[0046] S103: By driving the drive unit to run, the drive unit drives the sludge drive wheel 26 to rotate under the drive of the auxiliary power unit. The sludge drive wheel 26 will drive the incoming sludge to roll, and carry the sludge to roll onto the discharge platform 23. As the discharge platform 23 slopes, it slides into the side fault push column 10.

[0047] S105: The drive unit drives multiple sliding push columns 10 to slide up and down together. When the sliding push column 10 is pushed up, the tilt angle of the top surface is parallel to the top surface of the adjacent fixed ladder plate 9 on the side, which causes the sliding push column 10 to push the falling sludge upward. Under the upward push, the sewage contained in the sludge flows down through the water outlet channel 11 and enters the inclined filter plate 7 below for further filtration.

[0048] S107: The overflowing sewage undergoes multiple filtrations through the first activated carbon filter plate 25 below;

[0049] S109: The wastewater after multiple filtrations is discharged from wastewater outlet 6;

[0050] S1011: The filtered sludge is pushed forward segment by segment by the fault pusher column 10. After multiple pushes, the wastewater contained in it is filtered out, and the remaining sludge is pushed to the first discharge inclined port 8 and enters the first disc 68, and is conveyed downward through the upper through hole 69 in the middle.

[0051] S1013: Drive motor 59 to run, motor 59 drives the middle gear 61, which in turn drives the side gear 58 to rotate. The side gear 58 will drive the threaded lifting rod 64, causing the threaded lifting rod 64 to move up and down.

[0052] S1015: The threaded lifting rod 64 drives the second disc 65 to move up and down reciprocally. The distance between the second disc 65 and the first disc 68 will change continuously. By changing the distance, the sludge that descends along the trajectory is compressed and stretched, thus achieving a better sludge extraction effect.

[0053] S1017: The sludge inside the left cavity is compressed by the compression motion generated by the compression component and finally discharged from the sludge outlet 18.

[0054] To facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process will be described in detail below.

[0055] In practical applications, sludge is fed into the sludge feed hopper 3. The sludge falls from the feed channel 21 and enters the sludge drive wheel 26 below. When the motor 2 41 is driven, the motor 2 drives the pulley 5 43 to rotate. The pulley 5 43 drives the pulley 6 49 to rotate via the belt 3 50. The pulley 6 49 drives the rotating shaft 3 40 inserted in the middle to rotate. The rotating shaft 3 40 drives the bevel gear 2 39 at the end. After the bevel gear 2 39 rotates, it drives the bevel gear 1 38 meshing on the side to rotate. The bevel gear 1 38 drives the side connecting... The second rotating shaft 37 drives the upper-mounted pulley 35, which in turn drives the first pulley 32 via the first belt 36. The first pulley 32 drives the centrally inserted rotating shaft 30 to rotate, which in turn drives the third pulley 31 to rotate. The third pulley 31 drives the fourth pulley 28 via the second belt 33. The rotation of the fourth pulley 28 drives the connected sludge drive wheel 26, which in turn carries the falling sludge along with it. The sludge inside is carried to one side by the rolling and tumbling motion. As the sludge rolls, it enters the side fault pusher 10. When the rotating shaft 3 40 rotates, it drives the eccentric rotating wheel 48 at the other end to rotate. The eccentric rotating wheel 48 then drives the side-eccentrically connected drive plate 47, which pushes the fault pusher 10 up and down. As the fault pusher 10 moves up and down, the sludge falling above it is continuously pushed up. Since the top surface of each fault pusher 10 is inclined to the same side, the sludge on it will fall onto the next adjacent fixed ladder plate 9 as the slope of the slope increases. As the sludge slides upwards, the wastewater it contains flows down from the outlet channel 11, passes through the filter screen 12 at the top, and falls onto the inclined filter plate 7 below. Some of the wastewater containing impurities or larger particles is intercepted by the inclined filter plate 7 and slides to the left along the slope of the inclined filter plate 7, entering the left cavity through the second discharge inclined port 17. The filtered liquid is then filtered again and passes through the first activated carbon filter plate 25 below for multiple filtrations. Finally, the filtered liquid is discharged from the wastewater outlet 6.

[0056] As the fault-push column 10 pushes the sludge forward step by step in a fault-like manner, the sludge's transport path increases due to the multiple intermittent inclined planes, thus extending the sludge's solidification time. With the increased path, the sludge is pushed to the first discharge inlet 8, entering the first disc 68 in the left cavity and being conveyed downwards through the upper through-hole 69. During this process, the drive motor 59 operates, driving the central gear 61 to rotate. The rotation of the central gear 61 drives the side gear 58, which in turn drives the threaded lifting rod 64, which pulls the second disc 68. 5. The threaded lifting rod 64 moves up and down, and the upper part of the threaded lifting rod 64 reciprocates through the processing box 1 during the lifting and lowering motion. Since the first disc 68 is fixed on the left cavity wall, when the threaded lifting rod 64 moves up and down, it will pass through the first disc 68 and pull the second disc 65 to move up and down reciprocally. This causes the distance between the first disc 68 and the second disc 65 to change continuously. When the distance between them decreases, the space between them will also decrease. The sludge that shuttles through the box is squeezed by the compression motion between the first disc 68 and the second disc 65, which increases the coagulation of the sludge. This allows the compressed sludge to be discharged from the sludge outlet 18, making it convenient for secondary use.

However, it should be understood that the present invention is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.

9. A method for dewatering municipal environmental sludge, characterized in that, The municipal environmental sludge dewatering and solidification device according to claim 8 includes the following steps: The sludge is fed into the sludge feed hopper (3) and enters the lower semi-circular trough (22); By driving the drive unit to run, the drive unit drives the sludge drive wheel (26) to rotate under the drive of the auxiliary power unit. The sludge drive wheel (26) will drive the incoming sludge to roll, and the sludge will roll onto the discharge platform (23). As the discharge platform (23) slides on the slope, it slides into the side fault push column (10). The drive unit drives multiple fault push columns (10) to slide up and down together. When the fault push column (10) pushes up, the tilt angle of the top surface is parallel to the top surface of the adjacent fixed ladder plate (9), which causes the fault push column (10) to push the falling sludge upward. Under the upward push, the sewage contained in the sludge flows down through the water outlet channel (11) and enters the inclined filter plate (7) below for further filtration. The overflowing sewage undergoes multiple filtrations through the first activated carbon filter plate (25) below; The wastewater after multiple filtrations is discharged from the wastewater outlet (6); The filtered sludge is pushed forward segment by segment by the fault pusher column (10). After multiple pushes, the wastewater contained in it is filtered out, and the remaining sludge is pushed to the first discharge inclined port (8) and enters the first disc (68), and is conveyed downward through the upper through hole (69) in the middle. When the drive motor (59) runs, the motor (59) drives the middle gear (61), which in turn drives the side gear (58) to rotate. The side gear (58) then drives the threaded lifting rod (64) to achieve lifting and lowering motion. The threaded lifting rod (64) drives the second disc (65) to move up and down in a reciprocating manner. The distance between the second disc (65) and the first disc (68) will change continuously. The sludge entering the track by changing the distance between them is compressed and stretched, so as to achieve a better sludge extraction effect. The sludge inside the left cavity is compressed by the compression motion generated by the compression component and finally discharged from the sludge outlet (18).
