Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater, specifically to a sludge treatment device for industrial wastewater. Background Technology

[0002] Industrial wastewater refers to wastewater generated during industrial production processes. This wastewater may contain various harmful substances, and if it is discharged directly without proper treatment, it will cause serious environmental pollution. During the treatment of industrial wastewater, sludge will be produced. This sludge needs to be treated through specific technologies and methods to avoid further environmental pollution.

[0003] When cleaning sludge from industrial wastewater, the conventional method is to use mechanical equipment such as dredgers or sludge pumps. However, dredgers are not practical for industrial wastewater sludge removal and are not suitable for small sedimentation tanks. When using sludge pumps to extract sludge, the extraction position of the pipeline needs to be constantly moved to extract sludge from various locations in the sedimentation tank, but moving the pipeline is also quite troublesome. Therefore, a sludge treatment device for industrial wastewater is proposed to solve the above problems. Utility Model Content

However, dredgers are impractical for industrial wastewater sludge removal and are not suitable for small sedimentation tanks. Sludge pumps require constant repositioning of the pipeline to extract sludge from various locations in the sedimentation tank, which is also cumbersome.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the embodiments, by Figure 1-5The present invention discloses a sludge treatment device for industrial wastewater. The device includes a sedimentation tank 1, a moving device 2 on the outside of the sedimentation tank 1, a sliding rod 3 fixedly connected to the rear side of the sedimentation tank 1, a sliding sleeve 4 slidably connected to the outside of the sliding rod 3, a first hydraulic push rod 5 fixedly connected to the outside of both the moving device 2 and the sliding sleeve 4, the outside of both first hydraulic push rods 5 being fixedly connected to a mounting frame 6, a push frame 7 fixedly connected to the outside of the mounting frame 6, a rake device 8 and a push device 9 inside the sedimentation tank 1, a sludge pump 10 on the right side of the sedimentation tank 1, and an absorption nozzle 11 fixedly connected to the sludge pump 10 via a pipe inside the sedimentation tank 1.

[0029] The mobile device 2 includes a first motor 21 fixedly connected to the outside of the sedimentation tank 1. A threaded rod 22 rotatably connected to the inside of the sedimentation tank 1 is fixedly connected to the outside of the output shaft of the first motor 21. A transmission block 23 fixedly connected to the first hydraulic push rod 5 is connected to the outside of the threaded rod 22 via a threaded transmission.

[0030] In this embodiment, during actual use, the start of the first motor 21 will drive the threaded rod 22 to rotate, thereby causing the transmission block 23 to move outside the threaded rod 22 under the action of the thread, which in turn drives the first hydraulic push rod 5 to move.

[0031] The mounting bracket 6 is U-shaped and fits against the inner wall of the sedimentation tank 1, while the pusher 7 is L-shaped and tilted downwards on its right side.

[0032] In this embodiment, during actual use, the pusher 7 outside the mounting frame 6 can push the sludge. The inclined pusher 7 can fit more closely to the bottom surface of the sedimentation tank 1, making it easier to scoop up the settled sludge. The L-shaped pusher 7 can also push the sludge to prevent it from falling off.

[0033] The rake device 8 includes a second motor 81 fixedly connected to the outside of the sedimentation tank 1, a rotating rod 82 fixedly connected to the outside of the output shaft of the second motor 81 and rotatably connected to the inside of the sedimentation tank 1, and a plurality of rake rods 83 fixedly connected to the outside of the rotating rod 82.

[0034] In this embodiment, during actual use, the second motor 81 is a geared motor. The start of the second motor 81 can drive the rotating rod 82 to rotate, which in turn drives multiple rake rods 83 to rotate. The rotating rake rods 83 are flat and can pull the sludge to the right to bring the sludge closer to the suction nozzle. The rotation direction of the rake rods 83 is relatively slow to prevent the sludge from spreading, which facilitates the extraction of the suction nozzle 11 and also prevents the pipe from becoming blocked.

[0035] The pushing device 9 includes a fixed frame 91 fixedly connected to the left side of the sedimentation tank 1. Two second hydraulic push rods 92 are fixedly connected inside the fixed frame 91. The outer sides of the two second hydraulic push rods 92 are fixedly connected to the push plate 93.

[0036] In this embodiment, during actual use, when the second hydraulic push rod 92 is activated, the push plate 93 can move outward and push the sludge at the bottom of the sedimentation tank. When the push frame 7 pushes the sludge to the right, there is a blind spot behind it. The push plate 93 makes it convenient to clean the sludge on the left side.

[0037] The sedimentation tank 1 has a clearance groove on its inner left wall, the second hydraulic push rod 92 passes through and extends into the interior of the sedimentation tank 1, and the push plate 93 is located in the clearance groove.

[0038] In this embodiment, during actual use, the clearance groove allows the push plate 93 to be placed inside, preventing it from colliding with the push frame 7 when it moves. A sealing gasket should be provided between the second hydraulic push rod 92 and the sedimentation tank 1 to prevent wastewater from seeping out.

[0039] Working principle:

[0040] The sedimentation tank 1 is a storage device for treating and settling wastewater. After the wastewater is discharged into the sedimentation tank, some of the clean water will enter the next process through the upper pipe, while some of the sludge will settle to a certain extent. At this time, the first hydraulic push rod 5 can be activated to raise the push frame 7, and at the same time, the second hydraulic push rod 92 can be activated to push the push plate 93 to the right on the bottom left side of the sedimentation tank 1, so that no sludge accumulates under the push frame 7. Then, the push plate 93 is retracted and the push frame 7 is lowered. The first motor 21 is activated to move the mounting frame 6 along the direction of the threaded rod 22 and the sliding rod 3, and drive the push frame 7 to push the sludge to the right. At the same time, the activation of the second motor 81 will cause multiple rake rods 83 to pull the sludge, so that the sludge is close to the suction nozzle 11, so that the sludge pump 10 can extract the sludge.
