Description

Technical Field

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

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figures 1-4 As shown, this utility model discloses a coal-containing wastewater sludge treatment device, including a walking component 1, a lifting component 2, and a gripping component 3. The walking component 1 is slidably connected to a track 4, and the walking component 1 can move along the length of the track 4. As one embodiment, the track 4 can be in the shape of an I-beam and is installed at a predetermined position, such as above a sedimentation tank, so that the sludge treatment device can move above the sedimentation tank. Since the installation method of the track 4 is a relatively conventional technology and not the inventive point of this application, it will not be described in detail.

[0030] The walking assembly 1 includes a support frame 11, a power motor 12, a first walking mechanism 13, and a second walking mechanism 14. The support frame 11 is a frame structure consisting of a base plate and two side plates. The base plate of the support frame 11 is positioned below the track 4, with an installation space between the base plate and the track 4. The two side plates of the support frame 11 symmetrically cover both sides of the track 4. The power motor 12 is located within the support frame 11 (i.e., the power motor 12 is located within the installation space). The power motor 12 provides power to the first walking mechanism 13 and the second walking mechanism 14. Specifically, the power motor 12 is drive-connected to the first walking mechanism 13, and the first walking mechanism 13 is drive-connected to the second walking mechanism 14. The first walking mechanism 13 and the second walking mechanism 14 are symmetrically arranged on both sides of the track 4, and both the first walking mechanism 13 and the second walking mechanism 14 are slidably connected to the track 4.

[0031] As one embodiment of the first traveling mechanism 13, the first traveling mechanism 13 includes a first gear 131, a second gear 132, a first roller 133, a first pulley 134, a second pulley 135, a belt 136, a third gear 137, a fourth gear 138, and a second roller 139. The first gear 131 is a power gear, providing power for the rotation of the first roller 133 and the second roller 139.

[0032] The first gear 131 provides power to the first roller 133 in the following manner: the first gear 131 and the output shaft of the power motor 12 are coaxially and fixedly connected; the first gear 131 and the second gear 132 mesh; the second gear 132 and the first roller 133 are coaxially and fixedly connected; and the first roller 133 is set on the track 4 and slidably connected to the track 4.

[0033] The first gear 131 provides power to the second roller 139 in the following manner: the first pulley 134 and the first gear 131 are coaxially and fixedly connected; the first pulley 134 and the second pulley 135 are connected by a belt 136; the second pulley 135 and the third gear 137 are coaxially and fixedly connected; the third gear 137 and the fourth gear 138 mesh; the fourth gear 138 and the second roller 139 are coaxially and fixedly connected; and the second roller 139 is mounted on the track 4 and is slidably connected to the track 4.

[0034] Preferably, all the gears are located on the outside of the support frame 11 and are of the same type and size; all the pulleys are located on the outside of the support frame 11 and are of the same type and size; all the rollers are located on the inside of the support frame 11 and are of the same type and size. All the shafts are rotatably connected to the support frame 11 via bearings.

[0035] The second traveling mechanism 14 has the same structure as the first traveling mechanism 13, and will not be described again. The second traveling mechanism 14 and the first traveling mechanism 13 are connected by a drive shaft 5. Specifically, the drive shaft 5 passes through the support frame 11, and both ends of the drive shaft 5 extend from both sides of the support frame 11. The drive shaft 5 and the support frame 11 are rotatably connected. One end of the drive shaft 5 is coaxially and fixedly connected to the second pulley 135 and the third gear 137 of the first traveling mechanism 13, and the other end of the drive shaft 5 is coaxially and fixedly connected to the second pulley 135 and the third gear 137 of the second traveling mechanism 14.

[0036] The lifting assembly 2 can be an electric hoist. The lifting assembly 2 is fixedly installed at the bottom of the support frame 11 and can drive the grabbing assembly 3 to move up and down. The grabbing assembly 3 is suspended below the lifting assembly 2 and is used to grab sludge in the sedimentation tank. Specifically, the grabbing assembly 3 is a grab bucket, and the top of the grab bucket is connected to the chain of the electric hoist.

[0037] In operation, the power motor 12 starts, driving the first roller 133 and the second roller 139 to rotate, causing the traveling component 1 to move along the length of the track 4 until the gripping component 3 moves above the sedimentation tank. The lifting component 2 is then activated, lowering the gripping component 3 until it enters the sedimentation tank. The gripping component 3 is then activated to grab the sludge from the sedimentation tank. The lifting component 2 is then activated again to lift the gripping component 3. The traveling component 1 is then activated again, moving the gripping component 3 to the sludge storage area. The gripping component 3 is then activated again to unload the sludge, completing one sludge cleaning cycle.

[0038] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
