On the basis of summarizing advanced domestic and foreign experience, the sewage treatment process has been continuously improved, which has promoted the great development of sewage treatment equipment.

[0003] Sedimentation tanks are used to precipitate sewage, and the precipitated dirt will adhere to the bottom of the sedimentation tank. Nowadays, when cleaning the sediment at the bottom of the tank, the sludge is generally extracted through a suction pipe. However, the sewage is easily stirred during extraction, and the sludge is re-mixed into the sewage. Therefore, a sedimentation tank sludge extraction device is proposed. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a sedimentation tank sludge extraction device, which solves the problem that sewage is easily stirred during extraction and the sludge is re-mixed into the sewage.

[0012] Beneficial Effects

[0013] The utility model provides a sedimentation tank sludge extraction device, which has the following beneficial effects:

[0014] The sludge extraction equipment of the sedimentation tank is provided with a soft rubber cylinder, a thin rod, a plug and a push spring. When the thin rod is not in contact with the bottom of the tank, the plug seals the circular hole under the push of the push spring. When the soft rubber cylinder rotates downward and contacts the bottom of the tank, the thin rod pushes the plug away due to the push of the bottom of the tank, so that the circular hole is connected with the inside of the cavity belt. Then the suction tube can extract the sludge in the soft rubber cylinder below through the soft suction tube, the cavity belt and the circular hole.

[0015] The sedimentation tank sludge extraction equipment is provided with a hard rod. When the soft rubber cylinder rotates under the track, the hard rod contacts the tank bottom to prevent the track from flattening the soft rubber cylinder. The maximum compression amount of the soft rubber cylinder is limited to ensure that the sludge in the soft rubber cylinder can be stably extracted from the circular hole.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a sedimentation tank sludge extraction device, such as Figure 1-4 As shown, it includes a control panel 1, which is connected to a hydraulic structure and can adjust the height of the control panel 1. A crawler track 2 is arranged below the control panel 1. Four vertical plates 6 are fixedly connected to the bottom surface of the control panel 1. Rollers 3 are rotatably inserted at the lower ends of the four vertical plates 6. The two rollers 3 on the left and the two rollers 3 on the right are rotatably inserted at the inner ring sides of the left and right ends of the crawler track 2 respectively. A cavity belt 4 is fixedly connected to the inner ring surface of the crawler track 2. The outer ring surface of the cavity belt 4 is a cavity-shaped structure. The two vertical plates 6 at the front are fixedly connected by a horizontal plate 5. A suction pipe 7 is arranged in front of the control panel 1. The horizontal plate 5 is fixedly sleeved on the lower end of the suction pipe 7. The upper end of the suction pipe 7 is connected to the extraction equipment, and the extraction force is provided by the suction pipe 7.

[0023] A rotating cylinder 8 is provided on the inner ring side of the cavity belt 4, and the rotating cylinder 8 is rotatably sleeved on the rear end of the suction pipe 7. Soft suction tubes 9 are fixedly penetrated on the left and right sides of the rotating cylinder 8, and the other ends of the soft suction tubes 9 are fixedly penetrated through the inner ring side of the cavity belt 4. When the cavity belt 4 rotates, the rotating cylinder 8 is driven to rotate through the soft suction tube 9. A soft rubber cylinder 10 is fixedly connected to the outer ring surface of the crawler 2. There are multiple soft rubber cylinders 10, and the multiple soft rubber cylinders 10 are equidistantly distributed on the outer ring side of the crawler 2. When the soft rubber cylinder 10 contacts the bottom of the pool, the soft rubber cylinder 10 is deformed to ensure that it can form a closed space with the bottom of the pool, so as to ensure that the sewage outside the soft rubber cylinder 10 will not be stirred when the sludge is extracted.

[0024] A circular hole 11 is opened on the outer ring side of the track 2 and located inside the soft rubber tube 10. Four hard rods 18 are fixedly connected to the outer ring surface of the track 2 and located inside the soft rubber tube 10. The four hard rods 18 are in contact with the inner ring side of the soft rubber tube 10. The hard rods 18 limit the maximum deformation of the soft rubber tube 10. A thin rod 12 is arranged inside the circular hole 11. A plug 14 is fixedly connected to one end of the thin rod 12 close to the cavity belt 4. The diameter of one end of the plug 14 located in the circular hole 11 is equal to the diameter of the circular hole 11. The diameter of one end of the plug 14 located in the cavity belt 4 is larger than the diameter of the circular hole 11. The diameter of the thin rod 12 is smaller than the diameter of the circular hole 11. The plug 14 can block the circular hole 11, and the thin rod 12 will not block the circular hole 11.

[0025] The other end of the plug 14 is fixedly connected with a push spring 13, and the other end of the push spring 13 is fixedly connected to the inner wall of the cavity of the cavity belt 4, so that the push spring 13 pushes the plug 14 to block the circular hole 11. The end of the thin rod 12 located outside the track 2 is rotatably inlaid with a ball 17, and the thin rod 12 is coaxially arranged with the soft rubber tube 10 and the plug 14. When the ball 17 contacts the bottom of the pool, the ball 17 reduces the friction between the thin rod 12 and the bottom of the pool by rolling. The cavity belt 4 is located between four rollers 3, and a plurality of leakage grooves 16 are opened at one end of the soft suction tube 9 located inside the cavity belt 4. A waterproof motor 15 is fixedly connected to the front of the vertical plate 6 located on the left front, and the front end of the roller 3 located on the left front is fixedly connected to the output end of the waterproof motor 15. The two rollers 3 located on the left side of the rotating drum 8 and the two rollers 3 located on the right side of the rotating drum 8 are coaxially arranged respectively, and the rollers 3 located on both sides of the rotating drum 8 are symmetrically distributed about the axis of the rotating drum 8, and the waterproof motor 15 can drive the rollers 3 to rotate.

[0026] Working principle: the height of the control panel 1 is adjusted by the hydraulic structure, so that the soft rubber tube 10 under the crawler 2 contacts the bottom of the pool, and the suction tube 7 extracts from the cavity of the cavity belt 4 through the rotating tube 8 and the soft suction tube 9, and then the waterproof motor 15 is started to drive the left front roller 3 to rotate, and the crawler 2 is driven by the rotation of the roller 3. When the thin rod 12 is not in contact with the bottom of the pool, the plug 14 is pushed by the push spring 13 to block the round hole 11 to prevent the crawler 2 from being moved. The soft rubber cylinder 10 above the belt 2 extracts sewage. When the soft rubber cylinder 10 rotates to the bottom and contacts the bottom of the pool, the thin rod 12 pushes the plug 14 away from the circular hole 11 due to the push of the bottom of the pool, so that the circular hole 11 is connected with the inside of the cavity belt 4. Then the suction tube 7 can extract the sludge in the soft rubber cylinder 10 below through the soft suction tube 9, the cavity belt 4 and the circular hole 11. The soft rubber cylinder 10 blocks the extraction force of the circular hole 11 to prevent the sludge outside the soft rubber cylinder 10 from being extracted and stirred.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
