Description

A sludge treatment device for ecological and environmental protection Technical Field

[0001] This invention relates to the technical field of environmental protection equipment, specifically a sludge treatment device for ecological and environmental protection. Background Technology

[0002] Sludge refers to primary sedimentation sludge, excess activated sludge, humic sludge, digested sludge, and chemical sludge generated during wastewater treatment, excluding scum and grit from grit chambers. Sludge contains plant nutrients such as nitrogen, phosphorus, and potassium, as well as organic matter and water, and also contains a large amount of toxic and harmful substances.

[0003] Currently, the main method for treating sludge in wastewater treatment plants is landfilling, which takes two main forms: one is paying a landfill to dispose of the sludge; the other is digging pits for landfilling, which is costly and wasteful of land resources. Sludge itself contains a large amount of usable resources, and landfilling is a huge waste of these resources.

[0004] Currently, the usual method for treating sludge is to dry it. However, when the sludge contains a lot of moisture, the drying efficiency is low, and it takes a lot of time and consumes a lot of electricity. Summary of the Invention

[0013] As a further embodiment of the present invention: the intermittent engagement mechanism includes an incomplete gear rotatably mounted on the frame and a rack plate fixedly mounted on the side of the filter plate. The incomplete gear engages with the rack plate, and the rotation shaft of the incomplete gear is connected to a horizontal shaft rotatably mounted on the frame via a bevel gear set. The horizontal shaft is connected to the unidirectional transmission mechanism and the centrifugal drive mechanism respectively.

[0014] The frame is also fixedly installed with a crossbar, which is slidably connected to the filter plate. A third columnar spring is sleeved on the outer periphery of the crossbar, and the two ends of the third columnar spring are respectively connected to the frame and the filter plate.

A first plane and a second plane are formed in the grooves. The central axis of the lead screw is on the first plane, and the second plane intersects the central axis of the lead screw.

[0017] As a further embodiment of the present invention: the elastic telescopic structure includes a transmission tube rotatably mounted on the base, a transmission shaft slidably fitted with the transmission tube, and a first cylindrical spring disposed inside the transmission tube. The transmission tube is connected to the horizontal shaft via a first transmission belt. The second cylinder is fixed to the transmission shaft. One end of the first cylindrical spring is connected to the inner wall of the transmission tube, and the other end is connected to the end of the transmission shaft away from the second cylinder. A strip-shaped protrusion is formed on the outer wall of the transmission shaft, and a strip-shaped groove adapted to the strip-shaped protrusion is provided on the transmission tube.

[0018] As a further embodiment of the present invention: the centrifugal drive mechanism includes an elastic sliding component mounted on the horizontal axis and a follower structure mounted on the base, the follower structure being connected to the elastic sliding component and also connected to a plurality of the columns.

The first process is to spread the sludge flat and, in conjunction with the reciprocating motion of the filter plate, accelerate the removal of water from the sludge. The second process is to move the sludge by multiple columns to further promote the loss of water, which facilitates the subsequent drying process. Therefore, through the cooperation between various mechanisms and components, the sludge is efficiently dehydrated before drying, which can effectively improve the efficiency of the subsequent drying process. Moreover, the device has a high degree of automation and can reduce the burden on workers. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0035] Please refer to Figures 1-8. In this embodiment of the invention, a sludge treatment device for ecological and environmental protection includes a base 1 and two frames 2 fixedly installed on the base 1 and arranged opposite to each other, and further includes:

[0036] The filter plate 5 is movably disposed between the two frames 2 and is connected to an intermittent engagement mechanism installed on one of the frames 2. The intermittent engagement mechanism can drive the filter plate 5 to reciprocate along the width direction of the base 1.

[0037] A transverse plate 3 is movably mounted on the base 1 and located above the filter plate 5, and is connected to a threaded drive mechanism mounted on the base 1. The threaded drive mechanism is connected to the intermittent engagement mechanism through a one-way transmission mechanism.

[0038] Multiple columns 4 are movably provided on one side of the transverse plate 3, and the multiple columns 4 are connected to a centrifugal drive mechanism. The centrifugal drive mechanism is connected to the intermittent engagement mechanism and can drive the multiple columns 4 to rise and fall on the transverse plate 3.

[0039] It should also be noted that a water collection tank is provided on the base 1, which is located below the filter plate 5 and is used to collect the water filtered out by the filter plate 5.

[0040] During operation, the sludge to be treated is placed on the filter plate 5 (near the transverse plate 3). The threaded drive mechanism operates in the forward direction, driving the transverse plate 3 to move to one side. At this time, the one-way transmission mechanism is triggered, driving the intermittent engagement mechanism to move. The intermittent engagement mechanism then drives the filter plate 5 to reciprocate along the width direction of the base 1. In addition, the centrifugal drive mechanism is triggered, causing multiple columns 4 to rise and be extracted from the filter plate 5. Thus, under the simultaneous action of the movement of the transverse plate 3 and the reciprocating motion of the filter plate 5, the sludge in the filter plate 5 is spread out, accelerating the filtration of water from the sludge.

[0041] Subsequently, the threaded drive mechanism reverses its operation, driving the transverse plate 3 to move downwards to the other side to reset. During this process, the one-way transmission mechanism does not move, the reciprocating motion of the filter plate 5 terminates, and multiple columns 4 are inserted into the sludge. The transverse plate 3 drives multiple columns 4 to move along the length of the filter plate 5, which can effectively move the sludge in the filter plate 5 and further promote the removal of water from the sludge.

[0042] After the moisture removal process is completed, the staff can then dry the sludge inside the filter plate 5.

[0043] In summary, this device divides sludge treatment into two processes. The first process involves spreading the sludge evenly and coordinating with the reciprocating motion of the filter plate 5 to accelerate the removal of moisture from the sludge. The second process involves multiple columns 4 to move the sludge to further promote moisture loss, facilitating subsequent drying. Therefore, through the cooperation between various mechanisms and components, the device achieves efficient dewatering of sludge before drying, effectively improving the efficiency of subsequent drying processes. It also boasts a high degree of automation, reducing the workload of operators.

[0044] Please refer again to Figures 1, 2 and 5. The threaded drive mechanism includes a lead screw 7 rotatably mounted on the base 1, a threaded sleeve 9 sleeved on the lead screw 7 and threadedly connected to the lead screw 7, and a drive motor 6 mounted on the base 1.

[0045] One end of the lead screw 7 is connected to the output end of the drive motor 6, and the other end is connected to the one-way transmission mechanism. The transverse plate 3 is fixed to the threaded sleeve 9. The transverse plate 3 is also fixedly connected to the guide sleeve 10. The guide sleeve 10 is slidably connected to the guide rod 8 fixedly installed on the base 1.

[0046] Furthermore, since the transverse plate 3 needs to complete one horizontal reciprocating motion during the operation of the device, the drive motor 6 should be a servo motor with bidirectional drive capability at the output end. This application does not specify the specific model, and it can be selected according to actual needs.

[0047] During operation, the drive motor 6 first drives the lead screw 7 to rotate in the forward direction. The guide rod 8 and the guide sleeve 10 act as guides, so that the threaded sleeve 9 engages with the lead screw 7. Then, the threaded sleeve 9 can drive the transverse plate 3 to move along the length of the filter plate 5. In conjunction with the reciprocating motion of the filter plate 5, the sludge in the filter plate 5 can be spread out, increasing the rate of water filtration.

[0048] Please refer to Figure 6 again. The intermittent engagement mechanism includes an incomplete gear 12 rotatably mounted on the frame 2 and a rack plate 11 fixedly mounted on the side of the filter plate 5. The incomplete gear 12 engages with the rack plate 11, and the rotation shaft of the incomplete gear 12 is connected to a horizontal shaft 13 rotatably mounted on the frame 2 through a bevel gear set 14. The horizontal shaft 13 is connected to the unidirectional transmission mechanism and the centrifugal drive mechanism respectively.

[0049] A crossbar 34 is fixedly installed on the frame 2. The crossbar 34 is slidably connected to the filter plate 5. A third columnar spring 35 is sleeved on the outer periphery of the crossbar 34. The two ends of the third columnar spring 35 are respectively connected to the frame 2 and the filter plate 5.

[0050] In detail, the bevel gear set 14 includes a first bevel gear fixedly installed on one end of the horizontal shaft 13 near the filter plate 5 and a second bevel gear fixedly installed on the rotating shaft of the incomplete gear 12, and the second bevel gear meshes with the first bevel gear.

[0051] When the drive motor 6 drives the lead screw 7 to rotate in the forward direction, the one-way transmission mechanism is triggered, which drives the horizontal shaft 13 to rotate. Then, the horizontal shaft 13 drives the incomplete gear 12 to rotate through the bevel gear set 14. When the toothed part of the incomplete gear 12 meshes with the rack plate 11, it will drive the rack plate 11 to slide the filter plate 5 on the frame 2. Correspondingly, the third columnar spring 35 is compressed. After the toothed part of the incomplete gear 12 disengages from the rack plate 11, the third columnar spring 35 rebounds, causing the filter plate 5 to slide back to its original position. This cycle repeats, thus achieving the effect of the filter plate 5 reciprocating along the width direction of the base 1, which has a shaking effect on the sludge.

[0052] Please refer again to Figures 3, 4 and 7. The one-way transmission mechanism includes a first cylinder 15 fixedly installed on the end of the lead screw 7 away from the drive motor 6 and a second cylinder 18 movably installed on the base 1. The second cylinder 18 is connected to an elastic telescopic structure, which is connected to the horizontal shaft 13.

[0053] The first cylinder 15 has a plurality of transmission teeth equidistantly arranged along the circumference at one end facing the second cylinder 18, and the second cylinder 18 has a plurality of grooves equidistantly arranged along the circumference at one end facing the first cylinder 15, which are adapted to the transmission teeth. A first plane 1801 and a second plane 1802 are formed in the grooves. The central axis of the lead screw 7 is on the first plane 1801, and the second plane 1802 intersects with the central axis of the lead screw 7.

[0054] The elastic telescopic structure includes a transmission tube 16 rotatably mounted on the base 1, a transmission shaft 17 slidably fitted with the transmission tube 16, and a first columnar spring 19 disposed inside the transmission tube 16. The transmission tube 16 is connected to the horizontal shaft 13 via a first transmission belt 20. The second cylinder 18 is fixed to the transmission shaft 17. One end of the first columnar spring 19 is connected to the inner wall of the transmission tube 16, and the other end is connected to the end of the transmission shaft 17 away from the second cylinder 18. A strip-shaped protrusion 1701 is formed on the outer wall of the transmission shaft 17, and a strip-shaped groove 1601 adapted to the strip-shaped protrusion 1701 is provided on the transmission tube 16.

[0055] Specifically, when the drive motor 6 drives the lead screw 7 to rotate in the forward direction, the first cylinder 15 rotates in the forward direction along with the lead screw 7. At this time, the transmission teeth on the first cylinder 15 act on the first plane 1801, thereby causing the second cylinder 18 and the transmission shaft 17 to rotate. The transmission shaft 17 drives the transmission tube 16 to rotate through the strip protrusion 1701 and the strip groove 1601. The transmission tube 16 drives the horizontal shaft 13 to rotate through the first transmission belt 20, causing the filter plate 5 to reciprocate and triggering the centrifugal drive mechanism, causing the multiple columns 4 to rise.

[0056] Conversely, when the drive motor 6 drives the lead screw 7 to rotate in the opposite direction, the transmission teeth on the first cylinder 15 act on the second plane 1802. This causes the second cylinder 18 to give way, that is, the second cylinder 18 drives the transmission shaft 17 to perform telescopic movement within the transmission tube 16. The second cylinder 18 does not rotate, the reciprocating motion of the filter plate 5 terminates, and the multiple columns 4 are in the sludge, which plays a role in moving the sludge.

[0057] Please refer again to Figures 1, 4, 5 and 8. The centrifugal drive mechanism includes an elastic sliding component mounted on the horizontal shaft 13 and a follower structure mounted on the base 1. The follower structure is connected to the elastic sliding component and also connected to a plurality of the columns 4.

[0058] The elastic sliding assembly includes two fixed rods 21 fixedly mounted on the horizontal shaft 13, a sliding plate 22 slidably disposed on the two fixed rods 21, and two second cylindrical springs 24 respectively sleeved on the outer periphery of the two fixed rods 21. One end of the second cylindrical spring 24 is connected to the sliding plate 22, and the other end is connected to a boss 23 fixed to the end of the fixed rod 21 away from the horizontal shaft 13. A sleeve 26 is also slidably fitted on the horizontal shaft 13. The sleeve 26 is connected to the follower structure and is also connected to the sliding plate 22 through a first connecting rod 25. The two ends of the first connecting rod 25 are slidably connected to the sliding plate 22 and the sleeve 26 respectively.

[0059] The follower structure includes a guide plate 28 fixedly installed on the base 1, a connecting plate 27 slidably disposed on the guide plate 28 and rotatably connected to the sleeve 26, and a second connecting rod 29 rotatably connected to the connecting plate 27.

[0060] Two lifting plates 30 are slidably mounted on the base 1. A horizontal plate 31 is fixedly connected between the two lifting plates 30. A slider 32 is slidably mounted on the horizontal plate 31. The slider 32 is fixed to multiple columns 4 through a vertical plate 33. The vertical plate 33 is slidably connected to the horizontal moving plate 3. The end of the second connecting rod 29 away from the connecting plate 27 is rotatably connected to one of the lifting plates 30.

[0061] When the horizontal shaft 13 rotates, under the action of centrifugal force, the sliding plate 22 will slide away from the horizontal shaft 13 on the two fixed rods 21, so that the second columnar spring 24 is compressed. Correspondingly, the sliding plate 22 drives the sleeve 26 to slide on the horizontal shaft 13 toward the fixed rod 21 through the first connecting rod 25. Then, the sleeve 26 drives the connecting plate 27 to slide on the guide plate 28, so that the connecting plate 27 drives the horizontal plate 31 to rise through the second connecting rod 29 and the lifting plate 30, so that the multiple columns 4 are pulled out from the filter plate 5.

[0062] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
