Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a sludge removal machine for sedimentation tanks used in wastewater treatment. Background Technology

[0002] Wastewater refers to water discharged from domestic and industrial processes that has been polluted to a certain extent and has lost its original function. As people pay more and more attention to the environment, the treatment of wastewater has gradually become particularly important. Generally, before treating wastewater, coagulants are added to the wastewater and then it is injected into a sedimentation tank. After a period of time, sludge will be produced and settled. Then, it is scraped off by a sludge scraper and pumped out by a sludge pump.

[0003] In existing technologies, sludge pumps are mostly used to discharge sludge. However, since sewage tanks are large, the location of the sludge pumps needs to be changed frequently. Therefore, using sludge pumps is not suitable for discharging sludge from large sewage tanks. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art. In the prior art, most of the sludge pumps are used to discharge sludge. Since the sewage tank is large, the position of the sludge pump needs to be changed frequently. Therefore, the operation of sludge pumps is not suitable for sludge discharge in large sewage tanks. Therefore, a sludge discharge machine for sedimentation tanks in sewage treatment is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sludge removal machine for sedimentation tanks in sewage treatment includes a hull, a vertical plate, and a mounting frame. The vertical plate is slidably connected to one side of the hull, and the mounting frame is fixedly connected to the vertical plate.

[0007] The mounting frame is equipped with a conveying component, which includes a transmission belt, a reciprocating screw, a moving rod, and a transport cavity. Fixed plates are fixedly connected to both ends of the mounting frame. A rotating roller is rotatably connected to one end of each fixed plate away from the mounting frame. The transmission belt is sleeved between the two rotating rollers. The reciprocating screw is rotatably connected to the upper fixed plate, and one end of the reciprocating screw is fixedly connected to the rotating roller. One end of the moving rod is slidably connected to the upper fixed plate and is threadedly connected to the reciprocating screw. A spring is fixedly connected to the end of the moving rod away from the fixed plate, and the spring has an impact ball. Multiple transport cavities are equidistantly arrayed on the outer surface of the transmission belt.

[0008] Preferably, the conveying component further includes a collecting shovel, and inclined plates are fixedly connected to both sides of the mounting frame, with the collecting shovel fixedly connected between the two inclined plates.

[0009] Preferably, the vertical plate has a sliding groove, and an inclined sliding plate is fixedly connected in the sliding groove. One end of the sliding plate is rotatably connected to a swing plate via a rotating shaft, and a torsion spring is provided between the rotating shaft and the sliding plate.

[0010] Preferably, a hydraulic rod is fixedly connected between the upper end of the vertical plate and the upper surface of the hull.

[0011] Preferably, the end of the lower slide plate away from the swing plate is fixedly connected to a guide plate arranged in a figure-eight shape, and the end of the lower slide plate near the guide plate is located on the upper side of the hull.

[0012] Preferably, the collecting shovel is arranged in a right-angled trapezoid and is located on one side of the transport cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When the transport chamber rotates with the drive belt, it can transport the sludge upwards. When the transport chamber containing sludge moves, the upper part of the fixed plate is tilted onto the swing plate and slides into the hull through the lower slide plate, thus achieving the effect of collecting sludge. At the same time, as the hull moves continuously, it can transport the sludge in a large area of ​​the sewage tank to the outside, thus achieving the effect of quickly cleaning the sludge in the sewage tank.

[0015] As the moving rod moves closer to the transport chamber, it pushes the impact ball to strike the side wall of the overturning transport chamber. The impact causes the transport chamber to vibrate, which helps the silt to detach from the inner wall of the transport chamber. As a result, the silt in the transport chamber can be completely poured onto the swing plate until it slides into the hull for collection. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0023] Reference Figures 1-4 A sedimentation tank sludge removal machine for sewage treatment includes a hull 1, a vertical plate 8 and a mounting frame 2. The vertical plate 8 is slidably connected to one side of the hull 1, and the mounting frame 2 is fixedly connected to the vertical plate 8. A hydraulic rod 9 is fixedly connected between the upper end of the vertical plate 8 and the upper surface of the hull 1.

[0024] The mounting frame 2 is equipped with a conveying component, which includes a transmission belt 3, a reciprocating screw 13, a moving rod 12, and a conveying cavity 6. Fixed plates 11 are fixedly connected to both ends of the mounting frame 2. A rotating roller 10 is rotatably connected to the end of each fixed plate 11 away from the mounting frame 2. The fixed plates 11 support the rotating roller 10 and the transmission belt 3. The transmission belt 3 is sleeved between the two rotating rollers 10. The reciprocating screw 13 is rotatably connected to the upper fixed plate 11, and one end of the reciprocating screw 13 is fixedly connected to the rotating roller 10. One end of the moving rod 12 is slidably connected to the upper fixed plate 11. The reciprocating screw 13 is threadedly connected to the moving rod 12. A spring 15 is fixedly connected to the end of the moving rod 12 away from the fixed plate 11. An impact ball is provided on the spring 15. The impact ball is fixed to the end of the spring 15 away from the moving rod 12. When the impact ball hits the rotating transport cavity 6, the transport cavity 6 can vibrate. Multiple transport cavities 6 are arranged in an equidistant array on the outer surface of the transmission belt 3. The conveying component also includes a collecting shovel 5. The collecting shovel 5 is arranged in a right-angled trapezoid and is located on one side of the transport cavity 6. Inclined plates 4 are fixedly connected to both sides of the mounting frame 2. The collecting shovel 5 is fixedly connected between the two inclined plates 4. Both ends of the collecting shovel 5 are provided with openings.

[0025] A groove is provided on the vertical plate 8, and a downward sliding plate 7 is fixedly connected in the groove. A guide plate 14 with a figure-eight shape is fixedly connected to the end of the downward sliding plate 7 away from the swing plate 16. The end of the downward sliding plate 7 near the guide plate 14 is located on the upper side of the hull 1. The guide plate 14 can divert the silt on the downward sliding plate 7 to both sides to prevent the silt from accumulating in the hull 1. One end of the downward sliding plate 7 is rotatably connected to the swing plate 16 through the pivot 17. A torsion spring is provided between the pivot 17 and the downward sliding plate 7. The weight of the silt in a transport cavity 6 is less than the elastic force of the torsion spring. Therefore, when the silt is poured onto the swing plate 16, the swing plate 16 will not deviate and will remain in a straight line with the downward sliding plate 7.

[0026] In this invention, during use, the hull 1 is in a sewage tank. The hydraulic rod 9 retracts, causing the vertical plate 8 to move downwards until the bottom wall of the collecting shovel 5 is on the bottom wall of the sewage tank. This drives the hull 1 to move, which in turn moves the collecting shovel 5. At this time, sludge enters the collecting shovel 5. As the amount of sludge increases, it flows from the end near the transmission belt 3 into the transport chamber 6. Since one end of the lower rotating roller 10 is connected to an external servo motor, the external servo motor drives the rotating roller 10 and the transmission belt 3 to rotate. When the transport chamber 6 rotates with the transmission belt 3, it can transport the sludge upwards. When the transport chamber 6 containing sludge moves, the upper end of the fixed plate 11 is at this time... The conveying chamber 6 can be rotated 180 degrees, and the sludge in the conveying chamber 6 will fall onto the swing plate 16 and slide into the hull 1 through the lower slide plate 7, thus achieving the effect of sludge collection. As the transmission belt 3 continues to rotate, the rotated conveying chamber 6 moves down and squeezes the swing plate 16 to rotate with the connection point with the lower slide plate 7 as the fulcrum, and drives the torsion spring to twist. When the conveying chamber 6 passes the swing plate 16, the swing plate 16 returns to its original position under the rotation of the torsion spring, so that the sludge in the next conveying chamber 6 can slide onto the lower slide plate 7. Therefore, as the hull 1 moves continuously, the sludge in a large area of ​​the sewage tank can be transported to the outside, achieving the effect of rapid cleaning of the sludge in the sewage tank.

[0027] When the upper roller 10 rotates continuously, it drives the reciprocating screw 13 to rotate. The continuous rotation of the reciprocating screw 13 drives the moving rod 12 to move horizontally back and forth. Since the spring and the impact ball are fixedly hung on the upper end of the moving rod 12, when the moving rod 12 moves closer to the transport cavity 6, the moving rod 12 can push the impact ball to hit the side wall of the rotating transport cavity 6. The transport cavity 6 will vibrate after being hit, which is conducive to the sludge separating from the inner wall of the transport cavity 6. Thus, the sludge in the transport cavity 6 can be completely poured onto the swing plate 16 until it slides into the hull 1 for collection.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
